of a frame, indicated in whole at 10, located about midway the length of
the expansion coils shown in Fig. 1, and it may be supported by securing
it to the uprights C, C¹, or in any other suitable manner.
Said frame comprises two horizontally disposed longitudinal framing
members, 10ª, 10^{b}, which are connected at each end by cross-bars (not
shown).
Mounted on the supports 10ª, 10^{b}, are four uprights, 12ª, 12^{b},
13ª, 13^{b}. The uprights 12ª 12^{b} are connected at their upper ends
by a longitudinal framing member 14ª, and the uprights 13ª 13^{b} are
connected by longitudinal framing member 14^{b}, said framing members
14ª 14^{b} being also in turn connected at their ends by transverse bars
(not shown), said members constituting an open frame for the working
parts of the apparatus.
Mounted respectively upon the longitudinal framing members 10ª 10^{b},
approximately midway thereof, are two standards, 16ª 16^{b}, which are
rigidly secured together by a cross-bar 17, said standards and cross-bar
constituting a rigid support for the gearing now to be described.
Rotatably mounted upon the standards 16ª, 16^{b} is a driving shaft 18,
one end of which is journaled in the standard 16ª, and the other end in
a bearing-bolt 19 passing through the standard 16^{b}, which, being
threaded, is capable of fine adjustment.
Mounted upon and keyed to the shaft 18 is a wheel 19, the spokes 20 of
which support a rim 21, within which are set a series of pockets 22, the
inner surfaces of which are so shaped as to permit their receiving
successively, at the bottom of the wheel, a series of balls 23 and
holding the same during a travel of 180 degrees, or one-half revolution
of the wheel, when they are discharged as hereinafter described. This
wheel I will term an energy-storing wheel, since it acts through the
force taken from the expansion coils to raise the balls, the lowering of
which is to drive the wheel now to be described.
Loosely mounted on the shaft 18 is a wheel 24, smaller in diameter than
the wheel 19, the spokes 25 of which, secured to the hub 26, support a
rim 27, within which are set a series of pockets 28, which are adapted
to receive successively, at the top of the wheel, the balls 23, and
discharge the same when they have been lowered through 180 degrees or,
in other words, at the bottom of the wheel. The inner wall of the
pockets 28 is formed, for the most part, with a pronounced rounded
groove (indicated at 28ª), as shown above the ball in Fig. 18, which
groove lies under the ball when the pocket is in its uppermost position,
as shown in Fig. 17, said groove becoming less pronounced at one edge
towards the opposite portion of the pocket, at which point it has an
approximately level surface at one side, as shown in Fig. 18, and
indicated at 28^{b}; the subject of this arrangement being that the ball
may be readily discharged in this position, and securely held within the
pocket when the ball and pocket are in other positions. The wheel
24--which I will designate as the power-transmission wheel--is supported
upon ball bearings indicated at 28^{c}, 28^{d}, which are held in
position by collars 28^{e}, 28^{f}, both keyed to shaft 18.
Mounted upon a collar 29, which is keyed to the driving shaft 18, is a
ratchet wheel 30, engaging the teeth of which are two pawls 31, 32,
secured to one arm of a double-arm pawl-carrier 33, the other arm of
which is connected by a rod 34 to a lever 35, one end of which lever is
pivotally connected to a standard 36, secured to the frame, and the
other end of which is provided with a weight 36ª.
Near the inner end of the lever 35 connection is made by means of the
connecting rods 37 and 38, link 39 and rods 40, 41, with two levers
indicated at L, L, which are adapted to take power from the expansion
coils heretofore described, through the coil shafts J, J, to which
shafts are also connected the coil levers I, I, the ends of the latter
being connected to the strips G, G^{x} of the expansion coil by the
wires H, H¹, as already set forth and clearly illustrated in Figs. 2, 3,
5, 6 and 7.
As illustrated in Fig. 13, upon contraction of the
[Illustration:
_Fig. 8._
_Fig. 9._
_Fig. 10._
_Fig. 11._
BANGERTER’S PERPETUAL TIME CLOCK]
expansion coils, the wires H, H¹ will be pulled in the direction
indicated by the arrows, the ends of the long arms of the levers L,
L--through the movement of the shafts J, J--will rise, thereby, through
the rods 40, 41, link 39 and rods 38, 37, raising the lever 35, and
through the rod 34 actuating the pawl carrier 33, and through the pawls
31, 32, imparting rotary motion to the ratchet wheel 30, and, through
it, to the shaft 18 and the power-storing wheel 19, said pawl carrier
being returned to its normal position by the weight 36ª. Motion of said
wheel and shaft in the reverse direction is prevented by means of a
ratchet wheel 42, keyed to the collar 29, engaging the teeth of which
wheel is a detent 43, carried by a plate 44, secured to the supports 45,
affixed to the standard 16ª.
The hub member 26 of the power transmission wheel 24 is provided with a
sprocket wheel 46, which is adapted to engage and drive a sprocket chain
47, and thereby drive the great wheel of a clock mechanism or gearing of
any other machine adapted to the purpose.
Having shown the mechanism for driving the energy-storing wheel 19,
which, as already stated, is keyed to the shaft 18, I will now describe
the mechanism for driving the power transmission wheel 24, which runs
loose on the shaft 18.
It will be seen from an inspection of Fig. 16 that the wheel 19 is of
greater diameter than the wheel 24.
Suitably mounted between said wheels, on cross-bars 48, 49, I provide a
series of ball-storage runways designated in whole at 50 (see Fig. 14),
and, as shown in Fig. 16, these runways are laterally inclined
downwardly from the wheel 19 to the wheel 24.
Similar ball runways designated in whole at 51 are provided at the lower
portion of said wheels and between the same (Fig. 20), being mounted
upon cross-bars 52, 53, but the last named runways are laterally
inclined in the reverse direction to that of the runways 50.
The ball-storage runways 50 comprise inclined floor members 54, 54ª,
54^{b}, each having longitudinally a slight downward inclination in the
direction of the arrows. These runways also comprise longitudinally
extending walls 55, 56, 57, 58, one end of the wall 55 being curved to
meet one end of the wall 57, leaving a passageway 59 between it and one
end of the wall 56. One end of the wall 58 is similarly curved to meet
one end of the wall 56, leaving a passageway 60 between it and one end
of the wall 57. Thus are provided parallel runways 61, 62 and 63, with
passageways from one to the other, whereby a ball deposited in runway 61
will move continuously from that end of the series of runways to the
other end. The runway 61 is provided with an end wall 61ª, and adjacent
thereto the longitudinal wall 55 is provided with an opening 61^{b} to
permit the passage therethrough successively of balls from the
energy-storing wheel 19 to the runway 61.
Projecting through the standard 16^{b} is a threaded bolt 63ª, the end
of the shank of which is beveled, as clearly shown in Figs. 14 and 16,
the function of which is to eject from the uppermost pocket 22 of the
wheel 19, as the same revolves, the balls 23, and thrust them
successively into the runway 61.
At the lower end of the runway 63 is provided a laterally movable
receptacle 64, which has a receiving capacity of one ball only. Said
receptacle comprises a base 65 and perpendicular stop 66. The base 65 is
connected to the floor member 54^{b} of the runway 63 by a horizontally
disposed hinge 67, and to it is also affixed a plate 68, carrying a
downwardly extending lever arm 69, which is formed at its lower
extremity with an outwardly curving portion 70, which is adapted to
engage with the spokes 25 of the wheel 24 and be thereby pressed
inwardly, the result of which is to depress the outer end of the base 65
of the ball receptacle 64, inclining the same in such position that the
ball therein will fall into the adjacent pocket of the wheel 24, the
ball being prevented from falling therefrom on the opposite side by the
stop 71 secured to the standard 16ª. The center of gravity of the lever
arm 69 is such that when the curved lower portion is in its normal
forwardly extended position the rear side of the base 65 of the
receptacle 64 will be depressed and the forward side elevated, so that
the forward side will normally project above the floor level of the
runway 63 and serve as a stop to prevent more than one ball occupying
any of the space within said receptacle at one time.
The ball-storage runways 51 comprise inclined floor members 72, 72ª,
72^{b}, each having a slight downward inclination longitudinally in the
direction of the arrows. They also comprise longitudinally extending
walls 73,
[Illustration: _Fig. 12._
BANGERTER’S PERPETUAL TIME CLOCK]
74, 75 and 76, one end of the wall 73 being curved to meet one end of
the wall 75, leaving a passageway 77 between it and one end of the wall
74. One end of the wall 76 is similarly curved to meet one end of the
wall 74, leaving a passageway 78 between it and the other end of the
wall 75. There are thus formed parallel runways 79, 80 and 81, with
passageways from one to the other, whereby a ball deposited at the other
end of the runway 79 will move continuously from that end of the series
of runways to the other end. The runway 79 is provided with an end wall
82, and adjacent thereto the longitudinal wall 76 is provided with an
opening 76ª to permit the passage therethrough, at intervals, of balls
from the power-transmission wheel 24 to the runway 79. Adjacent the wall
82 is perpendicularly disposed pin 82ª whereby the balls, as they pass
through the opening in the wall 76 are deflected to pass through the
runway 79 in the direction of the arrow.
At the lower end of the runway 81 is provided a laterally movable
receptacle 83, which has a receiving capacity for one ball only. Said
receptacle comprises a base 84 and end stop 85. Said receptacle is
horizontally hinged at 86 to the floor member 72 of the runway 81, and
is provided with an outward extension 87, which is adapted to be engaged
by a shoulder 88 on the ball pockets 22, and thereby depress the outer
edge of the base of the receptacle in such a way as to eject the ball
therefrom, and place the same in the pocket of the wheel 19.
It will be seen that the hinge 86 (Fig. 19) is off center and when the
base 84 of the receptacle 83 is depressed at the rear the upper end of a
pin 89, projecting upwardly from the base 84 contacts with the upper
portion of the wall 74, thereby preventing the rear portion of the base
being depressed too low. When a ball is in said receptacle, the forward
end will be elevated so that a portion of the side edge of the base will
be projected above the floor member of the runway 81, serving as a stop
to prevent more than one ball occupying any of the space within said
receptacle. When one ball moves into a pocket 22, another ball quickly
moves into the receptacle, taking its position at the rear thereof. This
operation takes place when the base 84 is level with the floor member of
the runway 81, the outer end of the base rising as soon as the pocket
and its ball have passed by the projection 87.
It will be seen that the energy-storing wheel 19, which takes its motive
power through the shaft 18 from the expansion coils, acts to raise the
balls or weights from the lower ball runways 51 to the ball storage
runways 50. The wheel 19 may act at more or less irregular intervals,
while the power transmission wheel 24 acts--and must act--continuously
and regularly. This wheel takes and transmits power from the lowering of
the balls, which are delivered to it when the pockets are in the
position of the one shown uppermost in Fig. 15, and are discharged from
the pockets when in the position of the one shown lowermost in said
figure, in which position of the wheel the approximately flat surface of
the pocket (Fig. 18) is lowermost, or under the ball, permitting ready
discharge of same. From the delivery side of the power transmission
wheel 24 the balls are discharged into the runway 79, being deflected
into proper direction by the pin 83ª, thence passing through the
passageway 78 through the runway 80 in the direction of the arrow,
thence through the opening 77 into the runway 81, thence into receptacle
83, and when the shoulder 88 of the energy-storing wheel 19 reaches a
point opposite said receptacle the base of the latter is depressed,
which results in passing a ball into the wheel pocket; as the wheel
turns and the next pocket arrives in position another ball is taken on,
and so on, as long as there are any balls in the lower runway. When a
ball on the wheel 19 reaches the uppermost position, as shown in Fig.
16, it contacts with the ejector 63ª and is thereby passed into the
runway 61 and thence to the lower end of that series of runways, and in
the same way the balls following will take position in the upper series
of runways.
It will be understood that when my invention is applied to the operation
of a clock the power taken from the power transmission wheel 24 will be
given up gradually, being controlled by the pendulum or balance wheel
governed escapement in the usual way.
In the application of my invention as last above described the apparatus
will be designed and built to furnish energy sufficient not only to run
the clock, but provide a surplus for storage. On some days the variation
in temperature may be but two or three degrees, and on
[Illustration: _Fig. 12ª._
BANGERTER’S PERPETUAL TIME CLOCK]
other days it may be as high as twenty degrees. If the clock requires
for its operation the lowering of three balls each day the apparatus
will be so arranged that with an average daily temperature variation of,
say, six degrees, four balls will be raised, of which three will operate
the power transmission wheel and one will be held in storage. With a
variation of twelve degrees, eight balls will be raised, of which five
balls will be left in storage. If the ball storage runways each have a
holding capacity for one hundred balls, and the variation in temperature
is greater than required, the balls will soon be lifted from the lower
to the upper runways. Assuming that on certain days there will be no
variation in temperature, and as a result the energy-storing wheel
should not revolve, the running of the clock will not be interrupted,
for the power transmission wheel will continue revolving, taking its
power from the balls in storage.
I wish it understood that I do not confine myself to the precise details
of construction and arrangement of parts as herein set forth and
described or to the materials specified, as modification and variation
may be made without departing from the spirit of the invention as
defined by the appended claims.

[Illustration: BANGERTER’S NON-ELECTRIC REGULATOR TIME
CLOCK--ANNIVERSARY SELF-WINDING.
Patent Applied for, 1911.]
BANGERTER’S NON-ELECTRIC REGULATOR
TIME CLOCK
ANNIVERSARY SELF-WINDING
The Bangerter Anniversary Self-Winding Regulator deserves this title
because its construction embodies all the principles essential to a
Regulator to be the very best time-keeper. “Graham dead-beat escapement”
and a pendulum provided with means for keeping its gravity always the
same length, overcoming the variation which change in temperature
invariably brings about.
Another great improvement is the daily Self-Winding System, winding a
weight which is the only means of maintaining an even pull to the
delicate works of the clock. Wound by a force which requires attention
one minute a year only.
This invention relates to clocks, and particularly that class wherein a
pendulum escapement is employed and wherein the clock-train is weight
driven.
It is well known to those skilled in the art that the most accurate and
reliable clocks are those which are driven by a weight. Most of such
clocks are provided with a plurality of weights, one being used to
supply the energy necessary to strike the time, and the other the energy
for operating the clock-train, and in clocks of such construction they
have to be wound frequently, usually either daily or weekly.
Many attempts have been made to produce clocks which will run for a
relatively long time without requiring the attention of an attendant to
wind the same. In such clocks (other than electrical clocks) powerful
springs have been employed, one of such springs being used for
time-striking and the other for actuating the clock-train. Clocks of
this class designed to run for an extended length of time, such, for
example, as period of, say, a year or more, have been indifferent
time-keepers, due to the fact that the power of the springs becomes
materially lessened during the latter part of the cycle of operations.
Therefore, spring-operated clocks, calculated to be run for any great
length of time, have been more or less unsatisfactory, and have not gone
into very extensive use.
The object of my invention is to provide a clock which will not require
the attention of an attendant but once in a long period of time, and
which will also be an accurate time-keeper.
A further object is to provide a clock operated by a uniformly pulling
weight, the pull of which is not varied by the lifting of said weight.
A further object is to provide a power-storage device and power
transmission mechanism and automatic devices connected thereto, whereby
the power of said power-storage mechanism is utilized to wind up the
clock--that is to say, to lift the clock-train operating weight at
certain definitely recurring intervals of time.
A further object of my invention is to provide, in connection with such
power-storage mechanism, time-striking means operated by said
power-storage device, which being independent of the clock-train
operating means does not interfere therewith.
A further object of my invention is to provide a single power-storage
mechanism which will afford the power to strike the time and effect the
winding of the clock, doing away with two sets of mechanism (one for
each purpose), as heretofore used.
A further object of my invention is to provide such a power-storage
device that with one winding of the same the clock may be kept running,
and also striking the time, for a year or more in duration.
A further object of my invention is to provide means in connection with
said power-storage device whereby the winding of the clock-train does
not interfere with continuous running and perfect time-keeping of the
clock, and does not require any supplemental propelling mechanism for
the clock-train during the winding operation.

This is the most marvelous little machine that science has ever devised
to watch your house day and night. It is the truest of all Watch Dogs
and will in case of fire make such a loud and noisy alarm that you will
wake up from the deepest of sleeps. It calls when the fire is at its
infancy, in time to save you and your beloved ones. It is a most simple
little apparatus requiring no electricity, no wiring or connections, no
care of any kind; just as reliable after it has been hanging in your
room for twenty years as it was when newly installed.]
[Illustration: BANGERTER’S FIRE ALARM AND SPRINKLER.
More than a hundred million dollars is the yearly loss by fire in the
United States; 50 per cent. of this loss is by water. How important
therefore is Bangerter’s “Watch Dog Fire Alarm and Sprinkler,” regulated
to ring, first a loud call when a fire is in its infancy. A watchman or
anyone hearing the call can rush to the place and extinguish the fire.
The sprinkler will only work when the alarm call is not attended to. Our
Fire Alarm and Sprinkler system can be connected to piping from the
water main, or to the tank on the roof of a building, but can also be
installed in any place if there should be no water piping or tank. In
this case a water tank of from twenty to one hundred gallons of water
has to be installed. This tank can be set in any out of the way place.
Compressed air keeps this water under high pressure, and in case of fire
the valves are automatically opened and the sprinkler will act with
efficacious result.]
BRIEF BIOGRAPHY
OF
FRIEDRICH BANGERTER
Friedrich Bangerter can justly lay claim to being one of this country’s
leading inventors.
He has some fifty inventions to his credit.
He has been honored with Silver and Gold Medals and Diplomas.
His displays at great World’s Expositions have occasioned the utmost
favorable comment.
His splendid record speaks for itself and shows the profound student,
the practical machinist and brainy inventor of worldwide experience with
a long list of successes to his credit.
Born in Lyss, Switzerland, in 1868, at the age of 16 he entered the
machine shop of his town’s watch factory as an apprentice. There he was
favored with the opportunity to become familiar with all sorts of tools
and machines used in making watches.
By the age of 22 he so progressed that “all by himself” he constructed
all the necessary machines to make watches and added so many important
improvements, embracing such automatic devices and machines in which
hands, moving from place to place, picking up pieces of work, then
setting them in the right positions (operating with such perfection and
precision) that he was called a wizard. One of these automatic machines
would pick up blanks from a wire, set them in the machine from one to
twenty-four at a time and cut the teeth of watch gearing perfectly.
Another of Bangerter’s machines would take small, smooth, round steel
rods and automatically make perfectly finished pinions with pivots,
shoulders and smallest holes.
An automatic trumpet of his invention would play a complete tune and was
so simple in operation that a one-year-old child, by simply blowing in
it, could play it.
United States Patent 543668 for a Hair Clipper, issued to F. Bangerter,
San Francisco, is specified as follows:--
543668. Hair Clipper. Fred Bangerter, San Francisco, Cal., assignor, by
mesne assignments, to Charles H. Greene, same place. Filed July 21,
1894. Renewed July 2, 1895. Serial No. 554,715. (No model.)
Claim 1. In a Hair Clipper, the combination of the stationary and
movable plates, a pair of pivoted handles, one of said handles being
hinged or connected with one of said plates so that the device may be
turned to different angles, an opposing plate having its rear portion
recessed and provided with rearwardly and upwardly extending curved
arms, and the other handle having arms adapted to enter the recess of
said plate and engage the curved arms thereof in whatever position the
device is turned.
In 1892 he exhibited an automatic figure in a big department store in
San Francisco which drew a complete portrait of Christopher Columbus.
United States Patent 512089 was issued to Mr. Bangerter for an
“Automatic Delineating Machine,” a toy doll which would correctly write
the complete alphabet. Later he so improved this figure that it could
spell and talk while writing.
At the Paris Exposition in 1900 he exhibited a most remarkable machine
which made collar buttons. Three rods of metal were used at the same
time--one to make the head of the button, one the bottom or base, and
the other the stud. The three parts of the collar button were perfectly
made and finished.
The head was drilled and tapped, the stud was threaded and screwed into
the head while spun into the base or bottom. The manufactured collar
buttons fell into a box at the rate of 300 an hour--thus effecting a
great economy of metal.
