the mold and disk are clean and free of all metal, so the mold will
align with the trimming knives and mold knife. Then bring the four
front screws to a light bearing. Next tighten the three cap screws in
the disk, the center one first. Then tighten the four front screws
tight.
DISTRIBUTOR
DISTRIBUTOR BAR
The distributor bar is suspended between the distributor screws, and
is fastened to the distributor beam by two machine screws, and held
rigid by dowel pins.
There are seven combination rails along the bar. These combination
rails are cut away in various places, and certain of the rails or
combinations terminate directly above each channel in the magazine
entrance. The V-shaped end of the matrices have combinations or
distributing teeth which engage these rails. The bar is adjusted to
proper height and position so that the matrices, leaving the top
rails of the distributor box, do not bind on the aligning plate at
the back of the bar above the rails. These adjusting screws are in
the top of the distributor beam and rest on the yoke. On the later
machines the side-wise adjustment is made by an adjusting screw
fastened to the beam and banking against the right side of the yoke.
Each matrix has a combination corresponding to the combination
cut on the bar. The matrix is conveyed along the bar by the
distributor screws. As soon as the matrix reaches the end of the rail
corresponding to the combination on the matrix, it drops into the
channel, which guides it into the magazine.
CHANNEL ENTRANCE
The channel entrance is connected to the rear end of the magazine
on the magazine frame by two hinge screws. The entrance is held in
position by a spring at the right side and fastened to the magazine
frame.
The channel entrance consists of a number of flexible partitions,
which are assembled in the channel entrance partition plate, and act
as a guide for the matrices as they fall from the distributor bar
into the magazine.
Each partition rests against the side of a tooth in the automatic
stopping bar. If matrices become clogged in the entrance guides, they
pile up until they come in contact with the distributor screws. This
forces the partitions against the teeth of the automatic stopping bar
which causes the distributor driving mechanism to stop.
At the bottom of the channel entrance, on each side, and banking
against the magazine frame, are two adjusting screws which are used
to adjust the position of the channel entrance. The adjustment is
made to give the matrix free movement in transferring from the
channel entrance to the magazine under the channel entrance matrix
guard.
The upper end of the partitions sometimes get bent to one side and
thin matrices will fall into the wrong channel, causing the channel
to clog. The lower end of the partitions should set so they will
guide the matrices into the magazine. If they are sprung to either
side they will hold the matrices and keep them from entering the
magazine, causing the matrices to clog in the channel.
As the matrices are carried along the distributor bar by the screws,
there should be 1/16 of an inch between the bottom of a matrix
suspended on the distributor bar and the top of the channel entrance
partitions. Adjust, on models 1, 2, and 3, by the two screws in the
magazine frame which rest against the magazine supporting rods. Care
must be used in turning these screws, as they move the magazine also.
On Model 5 or later machines, this adjustment is set at the factory,
so it is rarely necessary to change it.
DISTRIBUTOR SCREWS
The conveyor screws are assembled on the distributor beam. Two of
these screws are in front of the distributor bar and one in the back.
As soon as the matrix leaves the distributor box it is conveyed along
the bar.
On the right-hand end of the screws are the driving gears which are
pinned to the screw shaft. These gears are properly timed at the
factory so as to carry the matrix in a vertical position without
bending.
There is a small pin projecting between two of the teeth of one gear
which must mesh with a tooth of its companion gear which is partly
cut away. This prevents the gears turning when they are improperly
timed.
This timing is readily accomplished by forming a small triangle with
the pins in the end of the gears and the openings in the gears, or
by placing the points of the upper and lower screws on the right end
in the same relative position before connecting the gears with the
distributor clutch shaft and gear.
Do not raise the back distributor screw while there are matrices on
the bar, as it is difficult to get their lugs in the right threads
again.
In closing the back screw see that the pin in the gear matches with
the short tooth in the front gear.
The old distributor screws were pitched four threads to the inch. The
new distributor screws have a much wider pitch, two threads to the
inch, consequently the matrices are moved along the bar twice as fast
to their respective channels. They are called “two-pitch screws.”
The two-pitch screws keep the matrices widely separated on the bar,
permitting a freer distribution of large matrices.
DISTRIBUTOR SCREW GUARD
The distributor screw guard is suspended between the front conveyor
screws and fits over the lower screw. This guard is for the purpose
of deflecting the matrix away from the lower screw as it drops from
the combination bar.
On models 1, 2, 3, 4, 5, 18, and 19, this guard is fastened by two
nuts to the two machine screws projecting through the front side of
the combination bar.
On models 8, 14, and 14-s-k this guard is loose, working on a fulcrum
rod, and operated by the distributor screw guard lever and the
right-hand locating bar. The lever is fastened to the right-hand
magazine frame guide by a fulcrum screw. Whenever the locating levers
are shifted for the purpose of raising or lowering the magazine
frames, a screw on the right-hand locating lever moves against the
guard lever and forces the guard upward. If there are any matrices
on the combination bar when attempting to change the position of
the magazines, this guard will strike them, and prevent the guard
from making the full upward stroke. Retarding the bar prevents the
locating levers and blocks from moving far enough to clear the bar
stops, thus not permitting the magazine frame to be moved.
If the magazine frames were changed with matrices on the bar, these
matrices would drop in the magazine that was in operating position,
causing wrong fonts in the magazine.
DISTRIBUTOR CLUTCH
The distributor screws are driven by a friction plate, keyed to
the distributor clutch shaft, and held against the face of the
distributor driving pulley by a spring inside of the distributor
clutch flange. This allows the clutch to slip when anything binds the
distributor screws.
The clutch shaft, operated by the friction plate, drives the
distributor screws by means of small gears which are timed so that
the matrices will hang perpendicular from the distributor bar.
To remove the distributor clutch, loosen the small screw on the
distributor clutch lever, and remove the clutch rod, spring, and
lever. Remove the hexagon head machine screw that holds the clutch
bracket to the distributor beam. Insert a screw driver between the
bracket and the beam at the upper end and pry the bracket away from
the beam. Lift the bracket off over the end of the shaft. Remove the
screw in the washer on the end of the clutch shaft. Take out the
spring which is behind the washer. The friction plate and pulley can
then be removed over the end of the shaft.
The friction plate should be kept free from oil at all times. There
is an oil hole in the flange of the pulley which should not be
overlooked when oiling. This hole should be kept stopped with a
counter sunk screw to prevent the oil working out on the drive belt.
DISTRIBUTOR STOPPING MECHANISM
The stopping bar is on the magazine channel entrance, and is operated
by the partitions and a spring hooked on the stopping bar and the
frame of the channel entrance.
The right side of the small teeth on the stopping bar should touch
each partition (which is flexible). When a matrix fails to enter
the magazine, the channel becomes clogged. This causes the matrices
to bind on the distributor screws which moves the partition to the
right, throwing the stopping bar from the clutch plate. This allows
the clutch lever screw to catch the clutch flange collar, force the
friction plate away from the driving pulley, and stop the distributor.
The clutch plate is held by two screws to the distributor clutch
lever.
The stopping bar should rest 1/32 of an inch on the clutch plate.
Adjust by loosening the screws which hold the plate. The holes in the
plate are elongated, to permit the plate being moved sidewise.
When adjusting be sure that the partitions are straight and touching
the teeth of the stopping bar on the right side. If not, when
straightening, they would cause the stopping bar to rest on the
clutch plate more than it should. This would prevent the clutch
lever and screw going into action instantly, which would cause thin
matrices to bend if caught.
THE SPIRAL AUTOMATIC
The new style distributor screw driving mechanism is termed the
spiral automatic.
The spiral automatic does away with the channel entrance stopping
bar and flexible entrance partitions. The channel entrances of
the new style are equipped with fixed partitions which can not
become bent, damaged or twisted out of adjustment by the action of
the distributing mechanism. Some of the features are: The channel
entrance partitions are thinner, allowing large matrices to pass
freely through the channels. The partitions are more rigid, although
thinner, because they are fixed and supported their entire length.
The entrance once set, does not have to be readjusted for different
sizes of matrices.
The partitions have guides at their lower end, which are arranged to
direct the various matrices into their respective channels by having
contact with the lugs instead of the body of the matrix, giving the
minimum amount of friction.
Two rotary wedges are pinned to the right end of the two front
distributor screw shafts. These wedges are placed so the thin edge
of one wedge is opposite the thick edge of the other. These wedges
rotate with the screws.
The small timing gear on the lower front distributor screw is loose
on the shaft. A connection between the screw and the gear is made by
two parallel pins, one on the gear and the other on the wedge. These
pins are held together by a spiral spring. The tension of the spring
should be so the slightest drag on the lower screw would allow the
pins to separate.
When anything binds or retards the revolution of the lower screw,
the two parallel pins separate, which changes the relation of the
wedges, causing them to lock. This locking of the wedges stops the
distributor screws and releases the tension of the clutch flange on
the distributor washer clutch flange permitting the driving pulley to
run free.
Assembled on the distributor clutch pulley washer clutch flange are
two distributor clutch stops. These are called left-hand stops.
Fastened to the distributor clutch flange are two distributor clutch
stops. These are called right-hand stops.
When the distributor is operating, the right-hand stops are held on
the left-hand stops by two spiral springs. One end of each spring
is fastened to an adjustable spring collar that slips over the
distributor clutch flange; the other ends are fastened to the pulley
washer clutch flange. These stops force the pulley washer flange
against the driving pulley, operating the distributor.
The tension of these spiral springs should be just tight enough to
hold the stops together. When the spiral locks, the tension of the
spring should permit the right stops to leave the left, releasing the
pressure on the driving pulley.
The tension of these springs can be adjusted by releasing the
clamping screw in the spring collar and turning the collar.
Remember that anything binding the lower screw will prevent the
distributor from operating.
A matrix not lifting properly, a dry distributor shaft bearing, or
the front rails of the distributor box bearing against the lower
screw will cause the screw to drag and stop.
If the spiral spring that holds the two pins together is too strong,
matrix ears or lugs will be bent. The spring, when at its proper
tension, should not bind the ears or lugs of the matrices when they
drag the lower screw.
When having trouble with the spiral automatic, do not change the
spring tension unless you are sure that it is necessary to do so.
The tension of the two springs, which hold the stops on the clutch
flange and washer flange, should be just strong enough to keep the
stops together. Too much spring tension will have a tendency to bend
matrices or prevent the proper working of the spiral.
To remove the distributor clutch flange and washer clutch flange on
a machine with the spiral automatic: Loosen the small screw on the
distributor clutch lever, and remove the clutch rod and lever. Remove
the two headless screws in the knurled lever flange on the end of the
clutch flange shaft. Remove the hexagon head machine screw that holds
the clutch bracket to the distributor beam. Insert a screwdriver
between the bracket and the beam at the upper end and pry the
bracket away from the beam. Lift the bracket off over the end of the
shaft. Remove the flat headed screw in the washer on the end of the
clutch flange shaft. Take out the spring which is behind the washer.
Take off the clutch flange shaft, stops and springs, assembled.
Unscrew the clutch pulley washer flange stop screw. The clutch pulley
washer flange can now be removed.
DISTRIBUTOR BOX
After the line has been transferred from the first elevator jaws to
the second elevator bar it is carried by the second elevator lever
to the distributor box. The distributor box contains the upper and
lower rails, tilting rails, matrix lift, font distinguisher, box bar
and point assembled, safety spring, lift cam lever, lift lever, lift
hinge pin, lift lever spring, lift spring, lift cam roll, and matrix
lift adjusting screw.
When the matrices are transferred from the second elevator bar to the
box bar they are supported at their lower end, by the tilting rails.
These rails release the strain on the matrix combination, and also
prevent matrices falling from the bar if there is any space between
the two bars.
To assure a good alignment of the two bars, the box bar pin hole at
the left is elongated, allowing play to the bar, which permits the
teeth of the second elevator bar to align easily with the box bar.
Matrices, coming into the box, hang to the rails on the box bar by
their teeth until they reach the vertical face of the box rails.
There are two upper and two lower rails held to the box plates (front
and back) by dowel pins and screws, so that the matrix will align
perfectly with all four rails and the bar point at the right end of
the box.
The rails must align the matrix to clear the distributor screws and
the aligning plate on the combination bar without binding. The matrix
must also pass between the vertical face of the rails and the bar
point. If these rails become worn, they will permit more than one
thin matrix to pass the bar point, or will not lift the matrix so
it will clear the screws properly, because of the unevenness of the
vertical face of the rails. This will bend the ears of the matrix
and stop the distributor.
The only remedy for worn rails is to apply new ones. Four new rails
must be applied, as the vertical faces of all the four rails wear,
and this is the only method of obtaining the proper alignment again.
A safety spring is pinned in a grooved part of the upper front rail
at the right end to prevent matrices turning and getting caught by
the lift when the shifter is suddenly withdrawn. It is only the
matrix ready to be lifted that need be held by the spring.
As the matrices are lifted by the matrix lift they must pass between
the vertical face on the rails and the bar point. All matrices
are the same thickness where they pass this point. There is just
sufficient space between the rails and the bar point for but one
thin matrix to pass when lifted by the matrix lift. If the bar point
becomes worn or broken it will permit more than one thin matrix to be
lifted to the distributor screws, resulting in the clogging of the
channel entrance or bending the matrix.
When the bar point becomes worn a new one should be applied. A new
bar point can be applied by removing the bar, and, with a small nail
set, driving out the two pins that hold the bar point. Put the new
point in its proper position, place the bar in the box, and test with
a thin matrix by raising the lift. The matrix should pass the point
without binding. When the point is set properly, remove the bar from
the box and drill two holes for the pins. Sometimes the bar point can
be drawn out a little by peening it with a small machinist hammer.
However, extreme care must be used, so the bar rails will not be
damaged by the hammer. Just a few light taps of the hammer should be
sufficient.
The font distinguisher is placed in the lower right end of the
box, between the two lower rails. All the matrices must pass this
distinguisher. When properly adjusted, it will stop all matrices of
a different font size to the one being used, or one of the same font
turned backwards. To change font distinguisher, turn the stud one
complete turn for each size. Turn the stud to the left for a smaller
size and to the right for a larger size.
On the multiple magazine machines the font distinguisher is
automatically changed when changing the position of the magazines.
Matrices must never be driven over the point of the distinguisher
when they stop in the box, but should be pushed to the second
elevator bar and the wrong font or the turned matrix removed. Driving
a matrix over the font distinguisher not only damages the matrix,
but it also often breaks the font distinguisher and causes serious
damage to the box by throwing the various parts out of their proper
alignment. When this happens it is almost impossible to get the box
back into proper shape.
The matrix lift mechanism is composed of the matrix lift lever,
the matrix lift cam lever, matrix lift spring, matrix lift cushion
spring, matrix lift hinge pin, matrix lift cam roll, and the matrix
lift.
This matrix lift is at the right end of the box and is held to
the lift lever by a fulcrum screw and forced against the font
distinguisher block by a small coil spring. The lift should set so
the back of the shoulder aligns with the vertical face of the rails.
If by any accident it is forced out of alignment to the left, the
lift cannot engage the bottom of the matrices and lift them over the
vertical face of the rails.
The shoulder and seat of the lift should be kept free from gum or
dirt so the matrices will not slip off while being raised. When the
shoulder and seat of the lift wear so that it will lift two thin
matrices or lift them crooked, the lift must be replaced by a new one.
The cam lever and lift lever are connected by a cushion spring which
absorbs the movement of the cam lever, if the lever hangs up. There
is an adjusting screw in the matrix lift lever which permits the lift
lever to be raised or lowered.
The matrix lift must raise the lugs of the matrices clear of the
vertical face of the box rails. If it does not do this, thin
matrices, when being moved by the distributor screws, would be forced
against the screws and become damaged. To adjust the lift, turn the
distributor screws by hand until the cam roller is at the low part
of the cam, place a thin matrix in the distributor box against the
vertical face of the rails, then adjust screw until the shoulder of
the lift is not more than 1/64 of an inch under the bottom of the
matrix. The lift then should raise the matrix 1/32 of an inch above
the top rails in the distributor box when the cam roller is at the
highest part of the cam. After adjusting the lift, be sure that the
adjusting screw locknut is tight.
The buffer of the distributor shifter should come in the box almost
to the distributor lift, but should never come in far enough to
engage the lift. The distance the shifter can travel into the box
is regulated by a stop screw which sets in the shifter slideway.
However, this screw sometimes gets broken off, comes out, or is worn
off. This would allow the shifter buffer to engage the lift and cause
undue wear.
LOWER DISTRIBUTOR BOX
For Models 2 and 4
On the upper distributor of a Model 2 or 4 the matrices are raised
over the rails by the matrix lift, the same as on any other model.
The upper portion of the inclined rails, however, are cut away. There
is a bridge on the upper distributor box on which the matrices for
the upper magazine ride until they catch on the distributor bar.
The matrices for the lower magazines have a slot in the bottom so
that they will not ride on the bridge. They fall from the upper box,
through a chute, into the lower box, where they are separated and
delivered to the lower distributor rail.
Care should be taken to see that the box escapements (or matrix lift)
work freely at all times. If dirt is allowed to accumulate, the
escapements will not work freely; the matrices will be prevented from
separating and cause them to clog in the box.
To adjust the escapement pawls (or matrix lift) in a lower box, turn
the screws until the matrix lift lever cam roll rides in the lower
part of the cam. Adjust with the adjusting screw until the point of
the male pawl clears the bottom of the slot in the matrix about 1/64
of an inch. See that the male pawl does not become bent; this point
should admit a thin matrix only between both pawls. The female pawl
must have a retaining hold on the matrix of at least 1/32 of an inch
when the male pawl is adjusted to clear the bottom of the slot.
DISTRIBUTOR BOX MATRIX LIFT CAM
This cam is fastened to the distributor back screw by means of a
taper pin. There is no adjustment of the cam. It should not be
detached unless badly worn, and then it should be replaced by a new
one.
To apply a new cam: Drive out taper pin and slip cam off the shaft,
placing a new one on the shaft in such a position that the holes
in the cam will match with the hole in the shaft. Use an 8 x 32
headless screw to hold the cam in position. Put a thick matrix with
a full size lug in the box in the regular way. See that the lift is
adjusted to raise the matrix 1/32 of an inch above the upper rails.
Then turn the distributor screws by hand, and when the matrix starts
to raise and enter the screws, the side of the matrix opposite the
distributor shifter should clear the threads on the distributor
screws 1/32 of an inch. If the matrix does not clear the threads 1/32
of an inch, loosen the small screw in the cam, turn the cam so that
when the matrix lift starts to raise the matrix it will clear the
threads properly. Fasten the cam securely with the screw, and then
run through a few lines to make sure that the cam is set right. Then
drill a hole in the shaft and fasten with a pin.
Before applying a new matrix lift cam, make sure that the upper and
lower rails in the box are not worn; if worn, renew the rails before
applying the new cam. It is seldom necessary to replace a lift cam,
due to the small amount of wear the cam undergoes.
DISTRIBUTOR TROUBLES
Considerable annoyance and lost time is caused by distributor
troubles. Some of the most frequent troubles may be traced to the
following:
The lifting of two thin matrices to the distributor is caused by
having too much space between the end of the bar point and the
vertical face of the rails, due to worn rails or bar point, or both.
Bent matrices are caused by the rails being worn, worn bar point,
matrix lift out of adjustment, worn lift cam, safety spring broken
or not functioning, conveyer screws out of time.
Matrices may drop in the wrong channel of the magazine if the
flexible guides become bent. If the lugs of the matrices are thicker
than those regularly running in that channel, the matrices will clog
in the entrance and stop the distributor.
The back conveyer screw, being set too far from the front screws,
will cause the matrices to fall in the wrong channel or twist as
they leave the distributor box rails. Adjust the screw with the two
adjusting screws at each end of the conveyer screw bearing.
A floor that is uneven or shaky will cause the matrices to drop in
the wrong channel.
