for good and great _Printing_, as for his many _Astronomical_ and
_Geographical_ exhibitions to the World. In his Youth he was bred up
to _Joynery_, and having learn’d his Trade, betook himself (according
to the mode of _Holland_) to Travel, and his fortune leading him to
_Denmark_, when the noble _Tycho Brahe_ was about setting up his
_Astronomical Observatory_, was entertain’d into his service for
the making his Mathematical-Instruments to Observe withal; in which
Instrument-making he shew’d himself so intelligent and curious, that
according to the general report of many of his personal acquaintance,
all or most of the _Syderal Observations_ set forth in _Tycho’s_ name,
he was intrusted to make, as well as the Instruments.
[Illustration: _Plate 4._]
And before these Observations were publish’d to the World, _Tycho_,
to gratify _Blaew_, gave him the Copies of them, with which he came
away to _Amsterdam_, and betook himself to the making of _Globes_,
according to those Observations. But as his Trade increased, he found
it necessary to deal in _Geographical Maps_ and _Books_ also, and
grew so curious in _Engraving_, that many of his best _Globes_ and
_Maps_ were _Engraved_ by his own Hands; and by his conversation in
_Printing_ of Books at other _Printing-houses_, got such insight
in this Art, that he set up a _Printing-house_ of his own. And now
finding inconveniencies in the obsolete Invention of the _Press_, He
contrived a remedy to every inconvenience, and fabricated nine of these
New-fashioned _Presses_, set them all on a row in his _Printing-house_,
and call’d each _Press_ by the name of one of the _Muses_.
This short History of this excellent Man is, I confess forraign to my
Title; But I hope my Reader will excuse the digression, considering it
tends only to the commemoration of a Person that hath deserved well
of Posterity, and whose worth without this small Monument, might else
perhaps have slid into Oblivion.

All these several Members, by their Matter, Form and Position, do
particularly contribute such an assistance to the whole Machine, that
it becomes an Engine managable and proper for its intended purpose.
But because the smallness of this altogether-Draft may obscure the
plain appearance of many of these Parts; Therefore I shall give you
a more particular description, and large delineation of every Member
in the _Press_: And first of the Wooden-work: Where, _Note_, that all
the Fram’d Wooden-work of a _Press_ is made of Good, Fine, Clean,
Well-season’d _Oak_.
¶. 1. _Of the_ Feet.
The _Feet_ (marked _a a_ in Plate 5.) are two Foot nine Inches and
an half long, five Inches deep; and six Inches broad, and have their
outsides Tryed to a true square, as was taught, _Numb._ 5. §. 15. It
hath (for ornament sake) its two ends bevil’d away in a Molding, from
its upper-side to its lower, about four Inches within the ends; about
four Inches and three quarters within each end of each Foot is made in
the middle of the Breadth of the upper-side of the Foot a Mortess two
Inches wide, to receive the _Tennants_ of the lower end of the _Cheek_,
and the _Tennant_ of the lower end of the _Hind-Post_: The Mortess for
the _Cheek_ is eight Inches long, _viz._ the Breadth of the _Cheek_:
And the Mortess for the Hind-Post is four Inches long, _viz._ the
square of the _Hind-Post_.
¶. 2. _Of the_ Cheeks.
The _Cheeks_ (marked _b b_ in Plate 5.) are five Foot and ten Inches
long (besides the _Tennants_ of the top and bottom) eight Inches
broad, and four Inches and an half thick. All its Sides are tryed
square to one another. It hath a _Tennant_ at either end, its lower
_Tennant_ marked _a_ to enter the Fore-end of the Foot, runs through
the middle of the Breadth of the _Cheek_, which therefore is made to
fit the Mortess in the _Foot_, and is about four Inches long, and
therefore reaches within an Inch of the bottom of the _Foot_; But the
_Tennant_ at the upper end of the _Cheek_ marked _a_, is cut athwart
the breadth of the _Cheek_, and therefore can have but four Inches and
an half of Breadth, and its thickness is two Inches, Its length is four
Inches; so that it reaches into the Mortess in the _Cap_, within half
an Inch of the Top.
In the lower end-_Tennant_ is two holes bored, within an Inch and an
half of either side, and within an Inch and an half of the Sholder,
with a three quarter Inch _Augure_, to be pin’d into the _Feet_ with an
Iron Pin.
In the middle of the upper _Tennant_, and within an Inch and an half
of the Sholder, is bored another hole, to Pin the _Tennant_ into the
_Cap_, also with an Iron Pin.
Between _b c_ two Foot and half an Inch, and three Foot seven Inches
of the Bottom-Sholder of the _Tennant_, _viz._ from the top of the
_Winter_ to the under Sholder the _Till_ rests upon, is cut flat away
into the thickness of the _Cheek_, three Inches in the Inside of the
_Cheek_; so that in that place the _Cheek_ remains but an Inch and an
half thick: And the _Cheeks_ are thus widened in this place, as well
because the Duftail _Tennants_ of the _Winter_ may go in between them,
as also that the _Carriage_ and _Coffin_ may be made the wider.
Even with the lower Sholder of this flat cutting-in, is made a Duftail
Mortess as at _d_, to reach eight Inches and an half, _viz._ the depth
of the _Winter_ below the said Sholder. This Mortess is three Inches
wide on the inside the _Cheek_, and three Inches deep; But towards the
inside the _Cheek_, the Mortess widens in a straight line from the said
three Inches to five Inches, and so becomes a Duftail Mortess. Into
this Duftail Mortess is fitted a Duftail _Tennant_, made at each end of
the _Winter_.
Two Inches above the aforesaid Cutting-in, is another cutting-in of
the same depth, from the Inside the _Cheek_ as at _e_. This cutting-in
is but one Inch broad at the farther side the _Cheek_, and an Inch
and a quarter on the hither-side the _Cheek_. The under-side of this
Cutting-in, is straight through the _Cheek_, _viz._ Square to the sides
of the _Cheek_: But the upper-side of this Cutting-in, is not square
through the _Cheeks_, But (as aforesaid) is one quarter of an Inch
higher on the fore-side the _Cheek_ than it is on the further side; So
that a Wedge of an Inch at one end, and an Inch and a quarter at the
other end may fill this Cutting-in.
At an Inch within either side the _Cheek_, and an Inch below this
Cutting-in, as at _f f_, is made a small Mortess an Inch and an half
wide, to which two _Tennants_ must be fitted at the ends of the
_Till_, so that the _Tennants_ of the _Till_ being slid in through
the Cutting-in aforesaid, may fall into these Mortesses, and a Wedge
being made fit to the Cutting-in, may press upon the _Tennants_ of the
_Till_, and force it down to keep it steddy in its place.
Here we see remains a square Sholder or substance of Wood between
two Cuttings-in; But the under corner of this square Sholder is for
Ornament sake Bevil’d away and wrought into an _Ogee_.
At two Inches above the last Cutting-in, is another Cutting-in, but
this Cutting-in goes not quite through the breadth of the _Cheek_, but
stops at an Inch and an half within the further side the _Cheek_; So
that above the _Till_ and its _Wedge_ is another Sholder or substance
of Wood, whose upper Corner is also Bevil’d away, and wrought to a
Molding as the former.
The last Cutting-in is marked _g_, and is eight Inches and a quarter
above the Sholder of the _Till_, that it may easily contain the depth
of the _Head_; The substance remaining is marked _h_. This Cutting-in
is made as deep into the thickness of the _Cheek_ as the former
Cuttings-in are, _viz._ three Inches; and the reason the _Cheek_ is
cut in here, is, that the _Cheeks_ may be wide enough in this place to
receive the _Head_, and its _Tennants_, without un-doing the _Cap_ and
_Winter_.
Just above this Cutting-in is made a square Mortess in the middle of
the _Cheek_, as at _i_, it is eight Inches long, and two Inches and an
half wide, for the _Tennant_ of the _Head_ to play in.
[Illustration: _Plate 5._]
Upon the fore-side of the _Cheek_ is (for Ornament sake) laid a Molding
through the whole length of the _Cheek_ (a square at the Top and Bottom
an Inch deep excepted) it is laid on the outer side, and therefore can
be but an Inch broad; Because the Cuttings-in on the inside leaves
the substance of Stuff but an Inch and an half thick, and should
the Moldings be made broader, it would be interrupted in the several
Cuttings in, or else a square of a quarter of an Inch on either side
the Molding could not be allowed, which would be ungraceful.
¶. 3. _Of the_ Cap _marked_ c _in Plate_ 5.
The _Cap_ is three Foot and one Inch long, four Inches and an half
deep, and nine Inches and an half broad; But its fore-side is cut away
underneath to eight Inches, _Viz._ the breadth of the _Cheeks_. Three
quarters of an Inch above the bottom of the _Cap_, is a small _Facia_,
which stands even with the thickness of the _Cheeks_; Half an Inch
above that a Bead-Molding, projecting half an Inch over the _Facia_.
Two Inches above that a broad _Facia_, also even with the thickness of
the _Cheeks_; and an Inch and a quarter above that is the upper Molding
made projecting an Inch and an half over the two _Facia_’s aforesaid,
and the thickness of the _Cheeks_.
Each end of the _Cap_ projects three Inches quarter and half quarter
over the _Cheeks_, partly for Ornament, but more especially that
substance may be left on either end beyond the Mortesses in the
Cap; and these two ends have the same Molding laid on them that the
fore-side of the _Cap_ hath.
Within two Inches and half quarter of either end, on the under-side the
_Cap_ is made a square Mortess two Inches wide, and four Inches and an
half long, _viz._ the thickness of the _Cheek_ inwards, as at _a a_,
to receive the Top _Tennants_ of the _Cheeks_; which Top _Tennants_
are with an Iron Pin (made tapering of about three quarters of an Inch
thick) pin’d into the Mortess of the _Cap_, to keep the _Cheeks_ steddy
in their position.
¶. 4. _Of the_ Winter _marked_ d _in_ Plate 5.
The Length of the _Winter_ besides the _Tennants_, is one Foot nine
Inches and one quarter of an Inch; The Breadth of the _Winter_
eight Inches, _viz._ the Breadth of the _Cheek_, and its depth nine
Inches; all its sides are tryed square; But its two ends hath each a
Duftail-_Tennant_ made through the whole depth of the _Winter_, to
fit and fall into the Duftail Mortesses made in the _Cheeks_: These
Duftail-_Tennants_ are intended to do the Office of a _Summer_, Because
the spreading of the ends of these two _Tennants_ into the spreading
of the Mortesses in the _Cheeks_, keeps the two _Cheeks_ in a due
distance, and hinders them from flying assunder.
But yet I think it very convenient to have a _Summer_ also, the more
firmly and surer to keep the _Cheeks_ together; This _Summer_ is only
a Rail _Tennanted_, and let into Mortesses made in the inside of the
_Cheeks_, and Screwed to them as the Rails described, _Numb._ 15. §. 4.
are Screwed into the Stiles of the _Case-Frame_; Its depth four Inches
and an half, and its breadth eight Inches, _viz._ the breadth of the
_Cheeks_.
¶. 5. _Of the_ Head _marked_ e _in_ Plate 5.
The length of the _Head_ besides the _Tennant_ at either end, is one
Foot nine Inches and one quarter of an Inch; The breadth eight Inches
and an half, and its depth eight Inches. The Top, Bottom and Hind-sides
are tryed Square, but the fore-side projects half an Inch over the Range
of the fore-sides of the _Cheeks_; in which Projecture is cut a Table
with a hollow Molding about it, two Inches distant from all the sides
of the fore-side of the _Head_: Its _Tennants_ are three Inches Broad,
and are cut down at either end, from the top to the bottom of the
_Head_, and made fit to the Mortesses in the _Cheeks_, that they may
slide tight, and yet play in them.
In the under-side of the _Head_ is cut a square Hole, (as at _a_,)
about four Inches square, and three Inches and an half deep, into which
the _Brass-Nut_ is to be fitted: And to keep this _Nut_ in its place
(lest the weight of it should make it fall out) is made on either side
the square hole, at about half an Inch distance from it, (as at _b b_)
a square Hole quite through the Top and Bottom of the _Head_ about
three quarters of an Inch wide; and into this square Hole is fitted a
square piece of Iron to reach quite through the _Head_, having at its
under-end a Hook turned square to claspe upon the under-side of the
_Nut_; and on its upper end a Male-Screw reaching about an Inch above
the upper-side of the _Head_, which by the help of a Female-screw made
in an Iron _Nut_, with Ears to it to turn it about draws the _Clasp_ at
the bottom of the Iron _Shank_ close against the _Nut_, and so keeps
it from falling out.
In the middle of the wide square Hole that the _Nut_ is let into,
is bored a round Hole through the top of the _Head_, of about three
quarters of an Inch wide, for the _Press-man_ to pour _Oyl_ in at so
oft as the _Nut_ and _Spindle_ shall want _Oyling_.
At three Inches from either end of the _Head_ (as at _c c_) is bored a
Hole quite through the top and bottom of the _Head_, which holes have
their under ends squar’d about two Inches upwards, and these squares
are made so wide as to receive a square Bar of Iron three quarters of
an Inch square; But the other part of these Holes remain round: Into
these Holes two Irons are fitted called the _Screws_.
The Shanks of these _Screws_ are made so long as to reach through the
_Head_ and through the _Cap_: At the upper end of these Shanks is made
Male-screws, and to these Male-screws, Iron Female-screws are fitted
with two Ears to twist them the easier about.
So much of these Iron-Shanks as are to lye in the square Hole of the
_Head_ aforesaid, are also squared to fit those square Holes, that when
they are fitted and put into the Holes in the _Head_; they may not
twist about.
To the lower ends of these Iron-Shanks are made two Square, Flat Heads,
which are let into and buried in the under-side of the _Head_; And upon
the Sholders of those two Flat Heads, rests the weight of the _Head_
of the _Press_; And by the _Screws_ at the upper end of the Shanks are
hung upon the upper-side of the _Cap_, and Screwed up or let down as
occasion requires.
[Illustration: _Plate 6._]
¶. 6. _Of the_ Till, _marked_ f _in_ Plate 5.
The _Till_ is a Board about one Inch thick, and is as the _Head_
and _Winter_, one Foot nine Inches and a quarter long, besides the
_Tennants_ at either end; Its Breadth is the Breadth of the _Cheeks_,
_viz._ eight Inches; It hath two _Tennants_ at either end as at _a a
a a_, each of them about an Inch and an half long, and an Inch and
an half broad, and are made at an Inch distance from the fore and
Back-side, so that a space of two Inches is contained in the middle of
the ends between the two _Tennants_; these _Tennants_ are to be laid
in the Mortesses in the _Cheeks_ delineated at _f f_ in Plate 5. and
described in this §. 10. ¶. 2.
In its middle it hath a round Hole about two Inches and an half wide,
as at _b_, for the Shank of the _Spindle_ to pass through.
At seven Inches and a quarter from either end, and in the middle
between the fore and Back-side, is made two square Holes through the
_Till_, as at _c c_, for the Iron _Hose_ to pass through.
¶. 7. _Of the_ Hind-Posts _marked_ a a _in_ Plate 6.
At one Foot distance from the Hind-sides of the _Cheeks_ are placed
upright two _Hind-Posts_, they are three Foot and four Inches long
besides the _Tennants_, which _Tennants_ are to be placed in the
Mortesses in the hinder-ends of the _Feet_; Their thickness is four
Inches on every side, and every side is tryed square; But within eight
Inches of the top is turned a round Ball with a Button on it, and a
Neck under it, and under that Neck a straight Plinth or Base: This
turn’d work on the top is only for Ornament sake.
There are six _Rails_ fitted into these _Hind-Posts_, two behind marked
_a b_, one of them standing with its upper-side at two Inches below
the turned Work, the other having its upper-side lying level with the
upper-side of the _Winter_.
These two _Rails_ are each of them _Tennanted_ at either end, and are
made so long, that the outsides of the _Hind-Posts_ may stand Range or
even with the outer-sides of the _Cheeks_; These _Tennants_ at either
end are let into Mortesses made in the insides of the _Hind-Posts_,
and Pin’d up with half Inch wooden Pins, Glewed in, as was shewn Vol.
1. _Numb._ 5. §. 17. Because the two _Hind-Posts_ need not be separated
for any alteration of the _Press_.
The two _Side-Rails_ on either side the _Press_ are _Tennanted_ at each
end, and let into Mortesses made in the _Cheeks_ and _Hind-Posts_,
so as they may stand Range with the outer-sides of the _Cheeks_ and
_Hind-Posts_; But the _Tennants_ that enter the Mortesses in the
_Cheeks_ are not pin’d in with Wooden Pins, and Glewed, because they
may be taken assunder if need be; But are Pin’d in with Iron Pins, made
a little tapering towards the entring end, so as they may be driven
back when occasion serves to alter the _Press_: And the _Tennants_
that enter the Mortesses in the _Hind-Posts_ are fastned in by a
Female-screw, let in near the end of the _Rail_, which receives a
Male-screw thrust through the _Hind-Posts_, even as I shew’d in §. 4.
the _Fore_ and _Back-Rails_ of the _Case-Frames_ was.
¶. 8. _Of the_ Ribs _marked_ b _in_ Plate 6.
The _Ribs_ lye within a Frame of four Foot five Inches long, one Foot
eleven Inches broad; its two _End-Rails_ one Inch and an half thick,
its _Side-Rails_ two Inches and an half thick; and the breadth of the
_Side_ and _End-Rails_ two Inches and an half. But the _Side-Rails_ are
cut away in the inside an Inch and an half towards the outer-sides of
the _Rails_, and an Inch deep towards the Bottom sides of the _Rails_,
so that a square _Cheek_ on either _Side-Rail_ remains. This cutting
down of the _Outer-Rails_ of the _Frame_ is made, because the Planck of
the _Carriage_ being but one Foot eight Inches and an half broad, may
easily slide, and yet be gaged between these _Cheeks_ of the _Rail_,
that the _Cramp-Irons_ Nailed under the _Carriage Planck_ joggle not on
either side off the _Ribs_, as shall more fully be shewn in the next §.
Between the two _Side-Rails_ are framed into the two _End-Rails_ the
two _Wooden-Ribs_ two Inches and an half broad, and an Inch and an half
thick; they are placed each at an equal distance from each _Side-Rail_,
and also at the same distance between themselves. Upon these two _Ribs_
are fast Nailed down the _Iron-Ribs_, of which more shall be said when
I come to speak of the Iron-work.
¶. 9. _Of the_ Carriage, Coffin _and its_ Planck, _marked_ a _in_ Plate
7.
The _Planck_ of the _Carriage_ is an Elm-Planck an Inch and an half
thick, four Foot long, and one Foot eight Inches and three quarters
broad; upon this _Planck_ at its fore-end is firmly Nailed down a
square Frame two Foot four Inches long, one Foot ten Inches broad, and
the thickness of its Sides two Inches and an half square; This Frame is
called the _Coffin_, and in it the _Stone_ is _Bedded_.
Upon each of the four Corners of this _Coffin_ is let in and fastned
down a square Iron Plate as at _a a a a_, with Return Sides about six
Inches long each side, half a quarter of an Inch thick, and two Inches
and a quarter broad; upon the upper outer-sides of each of these Plates
is fastned down to them with two or three Rivets through each side,
another strong Iron half an Inch deep, and whose outer Angles only are
square, but the Inner-Angles are obtuse, as being sloped away from
the Inner-Angle towards the farther end of each inner-side, so as the
_Quoins_ may do the Office of a Wedge between each inner-side and the
_Chase_.
[Illustration: _Plate 7._]
The Plates of these Corners (as I said) are let in on the outer
Angles of the upper-side of the Frame of the _Coffin_, so as the
upper-sides of the Plates lye even with it, and are Nailed down, or
indeed rather Rivetted down through the bottom and top-sides of the
Frame of the _Coffin_, because then the upper-sides of the Holes in
the Iron Plates being square Bored (that is, made wider on the
upper-side of the Plate, as I shall shew when I come to the making of
_Mathematical Instruments_) the ends of the Shanks of the Iron Pins
may be so battered into the Square-boring, that the whole Superficies
of the Plate when thus Rivetted shall be smooth, which else with the
exturberancies of Nail-heads would hinder the free sliding of the
_Quoins_.
At the hinder end of the Frame of the _Coffin_ are fastned either with
strong Nails, Rivets, or rather Screws, two Iron _Half-Joynts_, as at
_b b_, which having an Iron Pin of almost half an Inch over put through
them, and two _Match-half-Joynts_ fastned on the Frame of the _Tympan_,
these two _Match-half-Joynts_ moving upon the Iron Pin aforesaid, as on
an _Axis_, keeps the _Tinpan_ so truly gaged, that it always falls down
upon the _Form_ in the place, and so keeps _Register_ good, as shall
further be shewed in proper place.
Behind the _Coffin_ is Nailed on to its outside, a Quarter, as at _c
c_ this Quarter is about three Inches longer than the breadth of the
_Coffin_, it hath all its sides two Inches over, and three of them
square; but its upper-side is hollowed round to a Groove or Gutter an
Inch and an half over. This Gutter is so Nailed on, that its hither
end standing about an Inch higher than its further end, the Water that
descends from the _Tympan_ falling into it is carried away on the
farther side the _Coffin_ by the declivity of the farther end of the
Gutter, and so keeps the Planck of the _Carriage_ neat and cleanly, and
preserves it from rotting.
Parallel to the outer-sides of the hind part of the Planck of the
_Carriage_, at three Inches distance from either side, is Nailed down
on the upper-side of the Planck two Female-Duftail Grooves, into which
is fitted (so as they may slide) two Male-Duftails made on the two Feet
of the _Gallows_ (as at _d d_) that the _Tinpan_ rests upon; and by the
sliding forward or backward of these Duftail Feet, the heighth of the
_Tinpan_ is raised or depressed according to the Reason or Fancy of the
_Press-man_.
At three Inches from the hinder Rail of the _Coffin_, in the middle,
between both sides of the Planck, is cut an Hole four Inches square (as
at _e e_) and upon the hither and farther side of this Hole is fastned
down on each side a _Stud_ made of Wood (as at _f f_) and in the middle
of these two _Studs_ is made a round Hole about half an Inch over, to
receive the two round ends of an Iron Pin; which Iron Pin, though its
ends be round, is through the middle of the Shank square, and upon that
square is fitted a round _Wooden-Rowler_ or _Barrel_, with a Shoulder
on either side it, to contain so much of the _Girt_ as shall be rowled
upon it; And to one end of the _Rowler_ is fastned an Iron _Circle_ or
_Wheel_, having on its edge _Teeth_ cut to stop against a _Clicker_,
when the _Rowler_ with an Iron Pin is turned about to strain the _Girt_.
¶. 10. _Of the_ Tympan _and_ Inner-Tympan, _marked_ b _in_ Plate 7.
The _Tympan_ is a square Frame, three sides whereof are Wood, and the
fourth Iron. Its width is one Foot eight Inches, its length two Foot
two Inches; the breadth of the wooden Sides an Inch and an half, and
the depth one Inch.
On its short Wooden-side, _viz._ its Hind-end, at the two Corners is
Rivetted an Iron _Match-Joynt_, to be pinned on to another _Half-joynt_
fastned on the _Hind-Rail_ of the _Coffin_.
The other end, _viz._ the Fore-end of the _Tympan_ is made of Iron,
with a square _Socket_ at either end for the Wooden ends of the
_Tympan_ to fit and fasten into. This Iron is somewhat thinner and
narrower than an ordinary Window-Casement.
