Improved Type Founding Machine.
I, JAMES EDWARD THOMAS FOOT, of 21 Campana Road, Poole Park Estate,.
Fulham, in the County of Middlesex, do hereby declare the nature of this invention
to bo as follows :-
My invention has for its object a type founding machine on which moulds and
matrices of the usual form and construction may be used and which is simple and
practically automatic in its action.
In the practical construction of my improved type founding machine I secure
on a spindle mounted in suitable bearings and revolved in any suitable manner, a
drum the periphery of which has a number of flat surfaces formed on it. On each
of these flat surfaces I secure one half of a type mould of any construction the other
half being attached to a frame which is hinged at one end to the end of the first
mentioned half. The free end of the hinged half of each frame has hinged at one
side to it one end of a rod or bar which slides in, a slotted projection on one face of
the drum. The opposite end of each of said rods or bars has mounted on it a small
roller which runs on a cam secured to one of the bearings of the drum spindle or
other stationary part of the apparatus of such a shape as to effect the opening and
closing, through the medium of the rods or bars, of each mould during each
complete revolution of the drum.
Any suitable means may be employed for supplying the necessary quantity of
molten metal to each mould when closed.

COMPLETE SPECIFICATION.
Improved Type Founding Machine.
1 JAMES EDWARD THOMAS FOOT of 21 Campana Road Fulham in the County
of London, Type Founders' Engineer do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of my invention is to produce type at a greater speed, the moulds
and matrixes as used being of ordinary construction.
In the present construction of machines as used, the mould from which the type
is cast is attached to a frame which has a backward and forward movement to the
nipple, through which the metal is forced into the mould.
As the actual point of contact of the mouth of the mould with the nipple is
small compared with the time it is not in contact, my object has been to occupy all
that waste time.
To do so I have prepared a drum which runs vertically, the circumference
having surfaces upon it to which the moulds are attached.

page_text: My invention will be more clearly understood by following the accompanying
drawings and reference.
Fig. 1 being a front elevation, showing the operation of the mould by means
of the camb.
Fig. 2 plan in full.
Fig. 3 side elevation showing action of camb on matrix.
Fig. 4 sectional view of drum showing matrix box:
The drum A having a number of equal surfaces. upon its circumference to each
surface the bottom half of a type mould being fixed. The top half of the type
mould is bolted on to a small frame or block H, the said frame or block being
attached to the drum A by means of the centres D, which forms the fulcrum in
the operation of the top half of the mould closing upon the bottom half. The
supports D which contain the centres D are recessed into the side of the drum A.
They are connected by means of a stud passing through the drum A, the hole
through which the stud passes being slotted allowing the centres to be raised or
lowered. When the centre supports are in such a position as to allow the top half
of the mould in its operation to come perfectly flat and close on to the bottom
half of the mould, then the supports are held in that position by the nut D
(Fig. 1) binding the aforesaid supports to the drum A.
Fig. 4 is a sectional view of the matrix box E.
The matrix which is a piece of copper into which is indented the figure or letter
to be cast is placed in the aforesaid box in any required position, being held
there by the jaw F, the aforesaid jaw being operated like a vice by means of the
screws F1.
The matrix box E has attached at right angles to it a rod which passes and
projects through the drum A parallel with the surface of the bottom half of the
mould. A half round nut E 1 is attached to the other end of the aforesaid rod and
a open spring L2 being arranged between the half round nut E 1 and the side of
the drum, the matrix which is contained in the matrix box E, as previously
described, being held thus in tension against the face of the type mould.
M Fig. 1 is a sliding bar which operates the top half of the type mould. At
one end is attached à roller m 1 which travels in the camb B. The rod is kept in
its position by a slide bearing C through which the rod M is guided in its travel,
the bearings c being turned at one end, and being let into the drum, thus giving
the bearings a rotary motion, being needed, consequent upon the rod m working
out of its line in its travel round the camb B. The other end of the sliding rod M
is screwed, and has on it two nuts M 2. A connecting piece K consisting of a piece
of mechanism being sloted at one portion of it allowing it to pass freely into the
screwed portion of the rod M, is adjusted anywhere on the aforesaid screwed portion
of the rod M and securely locked by the nuts M 2. A small shaft forms the other
portion of the connecting piece K being at right angles with the sloted portion, the
shaft working free in the adjustable collar H 1, which is situated in the mould
block H Fig. 1. The top portion of the mould block, or frame is sloted, the
collar H 1 which has two flat sides upon it being adjustable in the aforesaid groove,
and being secured in position by the nut H 2. The camb B shown in Fig. 1
remains stationary, being attached to the bracket A 1 Fig. 2, the shaft n. to which
the drum A is fastened revolving freely through it.
B1 Fig. 1a tension piece let into the travel of the camb B at such a point as
to act at the time the mould is receiving the metal. By its acting on the roller M 1,
it brings the two sections of the type mould perfectly flat.
In Fig. 3 is shown a camb G attached to a stationary part of the machine.
Upon the mould leaving the nipple P', the half round nut 1 comes in contact with
the surface of the aforesaid camb, riding upon it, and so freeing the matrix, which
is contained in the matrix box from the face of the type. F 2 Fig. 4 are two screws
for keeping and even tension of the matrix against the face of the mould. When
the matrix is against the mould face the screws are adjusted against the drum A of
the type or letter.

page_text: The operation of the machine is as follows:-
The machine being set in motion each mould in its turn comes to the nipple P
through which the metal is forced into the mould, the two sections of the mould
being held down at the time by the tension piece B 1 as shown on Fig. 1, the matrix
being firmly held to the mould face by the spring E2 Fig. 4. The mould after
receiving the metal passes on its way untill the half round nut E 1 comes in contact
with the camb G Fig. 3, riding upon it, the aforesaid camb by its construction
pushing back the half round nut E 1, to which is attached the matrix box, and by
so doing freeing the matrix from the type face. At the time the freeing of the
matrix takes place, the roller M 1 has reached point q Fig. 1, when as will be scen
by the construction of the camb B, the roller travels up an incline opening the
mould and so allowing the type to be knocked out. The mould then gradually
closes, the half round nut freeing itself from the camb G and so passes again to the
nipple Pready for another operation.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a type casting machine a drum running vertically having a number of
surfaces upon its circumference, to which half sections of moulds are attached
Fig. 1, 2, 3.
2. In a type casting machine a camb being attached to any stationary part of
the machine, the drum rotating round it, the said camb having a tension piece
let in at such a point in its travel as when the mould receives its metal Fig. 1
3. In a type casting machine a bar or rod to one end being a roller working in
the aforesaid camb, the other end being attached to the top section of a mould by
means of a connecting piece, the rod being guided by a sliding bearing fixed into
the drum as to allow of a rotary movement Fig. 1.
4. In a type casting machine a mould block possessing an adjustable collar
Fig. 1, 2.
5. In a type casting machine a box for holding matrixes, the said box being
constructed to move parallel with the surface of the drum thus ensuring a straight
delivery Fig. 2, 3, 4.
6. In a type machine a camb so placed as to come in contact with a projection
on the drum, and by its action free the matrix from the face of the type Fig. 3.
7. The improved type founding machine described and illustrated in the
accompanying drawings.
Dated this 5th day of September 1894.
