Improvements in Type-founding Machines.
I, AUGUSTE FOUCHER of 71, Boulevard Voltaire, Paris, France, Machine
Builder, do hereby declare the nature of this invention to be as follows:-
My invention relates to type-founding machines in which the types are cast and.
dressed singly and particularly the machine forming the subject of former Letters
Patent dated the 22nd day of December 1887, No. 17649.
The invention consists in the combination in a single machine of a double set
of mechanism for moulding and dressing the type, so as to obtain two separate
types simultaneously, thus doubling the output of the machine.
The
The machine framing is composed of standards connected by top and bottom
cross-bars and in which is mounted the main shaft. for operating the various parts.
The frame supports a fixed bed-block in which are fitted to slide two vertically-
moving carriers for the sliding followers which form the undersides of the mould
cavities and discharge the type therefrom, each moving between a pair of steel
die blocks forming the lateral sides of the two mould cavities the die blocks
forming the one side of the moulds being fixed to the fixed bed block, and the die
blocks forming the other side being fixed to two bed blocks which are adjustably
fixed by bolts to permit of followers of different thicknesses being used according
to the letter being cast. At the front side of the mould cavities are arranged two
sprue breakers and opposite these sprue breakers are two cutters for removing the
fins which form at the shoulder and edges of the type body next to the followers,
the one sprue breaker and cutter being fixed on the bed block and the other sprue
breaker and cutter upon the adjustable bed block. On the front face of the bed
block is cast a bracket arm upon which is fitted the bed of two matrix carriers
which are adjustable and support the two tables upon which rest the two matrices
which are pressed against the mould by spring rods. The carriage has at its front
end an adjustable extension connected rigidly to it by a plate and screws, the
position of the extension being regulated by means of an adjusting screw.
carriage and its extension each carry the usual parts employed in making the type-
viz. a steel top die block for the corresponding mould cavity; a movable jaw
actuated in the one direction by a spring for seizing the type on its exit from the
mould and in the other direction by a traction rod for releasing it; an ejector for
delivering the type to the dressing or finishing devices, the two ejectors being
connected by a cross-head to enable them to be operated simultaneously; and a
cutter for removing the fins from the shoulder of the type, which project beyond
the surfaces of the die blocks when the type is in the mould. The dressing or
finishing devices are also duplicated, each consisting of two plates held apart by
distance blocks and provided with cutters for removing the lateral fins from the
shoulder of the type, one of the blocks acting also as a cutter to form the groove
between the feet of type and removing the part from which the sprue was broken.
The type setting mechanism situated next to the dressing devices, is also duplicated,
each consisting as usual of a guide curved at its upper end, serving to range the
types in a line as they descend from the slot of the corresponding dressing devices,
and conduct them to a movable composing stick forming a prolongation of the
guide. The pump in the melting pot which is supported as usual upon an
oscillating frame is provided with two injecting nozzles through which the molten
metal is injected into the two moulds by the single piston but in certain cases as
for casting large type, there may be two pumps in the same melting pot, one for
each mould. In order to concentrate the heat of the gas jets around the nozzles,

thereto.
a
The mechanism herein before described although in duplicate is all operated by
the same driving mechanism, as in the single type-founding machine, the operation
being as follows:-The double carriage receives reciprocating motion from a cam
through a lever which has an extensible arm for varying the stroke of the carriage.
The double matrix carrier receives reciprocating motion from its cam through
lever. The two holders carrying the mould followers are raised simultaneously
by a cam acting on a lever which is forked at its extremity for the purpose and
lowered by springs connected to tho lovor by books. Or tho hooks may bo.cop
nected by a cross-bar and acted on by a single spring, the downward movement
being limited by adjustable screw-stops and the upward movement by other screw-
stops. The two type ejectors are actuated simultaneously by a face cam groove
acting on a lever connected to a frame sliding in vertical guides on the rear face
of the mould bed. The horizontal upper end of said frame carries a screw-stud
which bears upon a stem fixed centrally on the cross-head before referred to and
also a lifter fork for ensuring the upward movement of the type ejectors when
raised by their respective springs. The two type ejectors are further operated
simultaneously during the movement of the carriage by means of a lever mounted
on said carriage, and carrying at its tail end a roller which rolls upon a raised
cam face fixed adjustably upon the rear face of the bed block. The pump piston
is operated in the ordinary manner by a cam acting on a lever connected by a rod
with a lever to which the piston rod is attached, for the purpose of raising the
same, the downward stroke of the piston being produced by a spring acting on the
lever.
The action is as follows: The pump piston forces the molten metal into
the two mould cavities enclosed by the steel die blocks, the followers, and the
matrices. The matrix carriers are then withdrawn from the bed block, so as to
disengage the matrices from the type faces, whereupon the carriage moves into
position during which movement the cutters remove the fins from the upper edges
of the shoulders of the type bodies remaining in their respective moulds. In order
to ensure that this double cutting action may be evenly performed, the carriage is
held down upon the bed block by means of an adjustable presser pivoted to the
carriage and provided with a crosshead carrying two friction rollers which travel
in slots in the fixed cheeks forming the lateral guides for the carriage, the said
rollers being caused to bear against the upper side of the slots by means of a
pressure screw. The carriage on the completion of its backward movement brings
the two jaws above the two mould cavities, into position for seizing the types, said
jaws being opened by the nuts on rods striking against a fixed abutment. At this
moment the mould followers are raised and lift the two types out of their moulds
and enter them between the jaws. Immediately afterwards the carriage again
moves forward and returns to position, during which movement the friction roller
rides upon the raised part of the cam surface and the opposite end of its lever
bears upon the cross head so as to cause the type ejectors to simultaneously press
downwards upon types in the jaws. During their forward traverse the two types
come in contact with the sprue breakers, which break off the sprue or jet, at
same time that the cutters reinove the fins from the underside of the type bodies.
The type bodies having been trimmed on the two sides, it ouly remains to trim
them on the top and bottom faces and to form the groove in the base. These two
operations are performed simultaneously when the carriage, by the downward
movement of the frame causing the screw-stud to abut against the upper end of
the stem and the type ejectors to descend, thus pushing the types out of the jaws
into the slots between the blocks where the lateral fins are removed by the cutters
and the groove cut in the base by the cutter provided for the purpose. The two
types will then be finished and the operation is repeated on the return of the
parts to position. During the injection of the metal the frame remains lowered
and exerts pressure upon the double carriage through the screw-stud screwed into
:

page_text: the crosshead and bearing upon the plate so as to hold the two top die blocks in
contact with the lateral die blocks. The finished types are pushed in succession
through the slots between the cutter blocks into the guide channels and are set up
in line in two movable composing sticks placed at the ends of the guides.
It will be observed that the whole of the above operations are performed in
duplicate in the present machine in the same manner as they are performed singly
in the ordinary single machine, the extent of motion of the piston, carriage, matrix
carriers, slides, and bar, being the same as in said single mrchines. This result is
obtained by arranging the duplicated parts of the machine in different longitudinal
vertical places, thus the second mould is situated in a different vertical plane
from the first one and not in the same line therewith, and similarly the extension
part is in a different plane to the main part of the carriage and the matrices and
injection nozzles and cutter blocks are arranged correspondingly, the two guide
channels being arranged one below and one in front of the other, in the manner
of the steps of a staircase. This arrangement in echelon of the duplicated parts
enables the strokes of the moving parts to remain unchanged and so permits of
obtaining, in the same time, two cast and finished types, instead of one. More-
over, it enables all parts of the machine to be overlooked by the operator, who can
thus readily superintend the working.

Improvements in Type-founding Machines.
1, AUGUSTE FOUCHER of 71, Boulevard Voltaire, Paris, France, Machine
Builder, 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 :-
My invention relates to type-founding machines in which the types are cast and
dressed singly, and particularly to the machine forming the subject of former
Letters Patent dated December 27th 1887, No. 17649.
The invention consists in the combination in a single machine of a double set of
mechanism for moulding and dressing the type, so as to obtain two separate types
simultaneously, thus doubling the output of the machine.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein
Figure 1 represents a front elevation, Figure 2 a plan, and Figure 3 &
longitudinal section, on line 1-2 Figure 2, of the improved machine.
Figure 4 is a detail plan of the top carriage, omitted from Figure 2.
Figures 5 and 6 shew respectively a longitudinal and horizontal section,
Figure 7 a plan, and Figure 10 a cross-section, on line 5—6 Figure 5, of the end of
the top carriage.
Figure 8 is a cross-section of the machine, on line 3-4 Figure 2, and Figure 9
a corresponding part plan of the same.
The machine framing is composed of two standards S S connected by too and
bottom cross-bars S¹ ST and in which is mounted the main shaft V for operating
the various parts.
A is a fixed bed-block in which are fitted to slide two vertically-moving
carriers B B¹ for the sliding followers b b which form the undersides of the mould
cavities and discharge the type therefrom, each moving between a pair of steel die-
blocks cc forming the lateral sides of the two mould cavities, the die-blocks c
C

page_text: forming the one side of the moulds being fixed to the fixed bed-block A and the
die-blocks c¹ forming the other side being fixed to two bed-blocks C C¹ which are
fixed adjustably by bolts c² to permit of followers b b' of different thicknesses: being
used, according to the letter being cast. At the front side of the mould cavities
are arranged two sprue-breakers a a' and opposite these sprue-breakers are two
cutters a a³ for removing the fins which form at the shoulder and edges of the
type-body, next to the followers 6 b¹, the one sprue-breaker a and cutter a² being
fixed on the bed-block A and the other sprue-breaker a¹ and cutter a³ upon the
adjustable bed-block C¹. On the front face of the bed-block A. is cast a bracket
arm A' upon which is fitted the bed D of two matrix-carriers D' which are
adjustable and support the two tables d'apon which rest the two matrices d³ which
are pressed against the mould by spring rods d³.
The carriage E has at its front end an adjustable extension E' connected rigidly
to it by a plate E' and screws e e², the position of the extension E¹ being regulated
by means of the adjusting screw e¹. The carriage E and its extension E' each
carry the usual parts employed in making the type-viz.: A steel top die-block e³
for the corresponding mould cavity, as shewn in Figure 3; a movable jaw F
actuated in the one direction by a spring f for seizing the type on its exit from the
mould and in the other direction by a traction rod t (Figure 1) for releasing it; an
ejector f¹ for delivering the type to the dressing or finishing devices (also as shewn
in Figure 3) the two ejectors f¹ being connected by a cross-head f to enable them
to be operated simultaneously; a cutter f³ for removing the fins from the shoulder
of the type, which project beyond the surfaces of the die-blocks c c¹ when the type
is in the mould.
The dressing or finishing devices are also duplicated, each consisting of two
plates G G (shewn separately on a larger scale in Figures 11 and 12) held apart
by distance blocks and provided with cutters go for removing the lateral fins
from the shoulder of the type, one of the blocks 9 acting also as a cutter to form
the groove between the feet of type and remove the part from which the sprue was
broken.
The type-setting mechanism situated next to the dressing devices is also
duplicated, each consisting, as usual, of a guide H, curved at its upper end h,
serving to range the types in a line as they descend from the slot of the
corresponding dressing devices and conduct them to a movable composing stick
forming a prolongation of the guide H.
The pump in the melting pot I which is supported, as usual, upon an oscillating
frame is provided with two injecting nozzles through which the molten metal
is injected into the two moulds by the single piston but in certain cases, as for
casting large type, there may be two pumps in the same melting pot, one for each
mould. In order to concentrate the heat of the gas jets ² around the nozzles i, the
hot gases of combustion are caused to pass out through the three chimneys ¿³.
The mechanism herein before described, although in duplicate, is all operated by
the same driving mechanism as in a single type-founding machine the operation
being as follows:-The double carriage E El receives reciprocating motion from
the cam L through the lever L' which has an extensible arm L2 for varying the
stroke of the carriage. The double matrix carrier D receives reciprocating motion
from the cam M through the lever M¹. The two holders B B' carrying the mould
followers 6 61 are raised simultaneously by the cam J acting on the lever J which
is forked at its extremity for the purpose, as shewn in Figure 9, and are lowered
by springs J connected to the lever J¹ by hooks J. Or the hooks may be
connected by a cross-bar and acted on by a single spring J³, the downward
movement being limited by adjustable screw-stops and the upward movement by
screw stops 63. The two type-ejectors f¹ are actuated simultaneously by a face
cam groove K acting on a lever K¹ connected to a frame K' sliding in vertical
guides on the rear face of the mould bed A. The horizontal upper end of frame K'
carries a screw-stud k which bears upon a stem k' fixed centrally on the cross-
head ƒ³ and also a lifter fork ³ for ensuring the upward movement of the type

page_text: ejectors when raised by their respective springs. The two type pushers flare
further operated simultaneously during the movement of the carriage E by means
of a lever N mounted on said carriage and carrying at its tail end a roller n which
rolls upon a raised cam face N¹ fixed adjustably upon the rear face of the bed-
block A. The pump piston I' is operated in the ordinary manner by a cam O
acting on a lever O₁ connected by a rod O' with a lever 08 to which the piston
rod is attached for the purpose of raising the same, the downward stroke of the
piston being produced by a spring acting on the lever O¹.
In
The action is as follows:-In Figures 2 and 3 the parts are shewn in position
for simultaneously casting the two types. The pump piston forces the molten
metal into the two mould cavities enclosed by the steel die-blocks c c¹ and e³, the
followers bb' and the matrices d². The matrix carriers D D' are then withdrawn
from the bed-block A, as shewn in Figure 8, so as to disengage the matrices d'
from the type faces whereupon the carriage E E' moves to the position shewn in
Figure 1, during which movement the cutters f³ remove the fins from the upper
edges of the shoulders of the type-bodies remaining in their respective moulds.
order to ensure that this double cutting action may be evenly performed, the
carriage E E' is held down upon the bed-block A by means of an adjustable
presser P pivoted at p to the carriage, provided with a cross-head carrying two
friction rollers p which travel in slots in the fixed cheeks A forming the lateral
guides for the carriage, the said rollers being caused to bear against the upper
side of the slots by means of a pressure screw p¹. The carriage E on the com-
pletion of its backward movement brings the two jaws F above the two mould
cavities into position for seizing the types, said jaws being opened by the nuts t' of
rods t striking against a fixed abutment Q. At this moment the mould followers b b¹
are raised and lift the two types out of their moulds and enter them between the
jaws F. Immediately afterwards the carriage E E¹ again moves forward and
returns to the position shewn in Figure 3 during which movement the friction
roller n rides upon the raised part of cam surface N¹ and the opposite end of
lever N bears upon the cross-head so as to cause the type ejectors fl to
simultaneously press downwards upon the types in the jaws F. During their
forward traverse the two types come in contact with the sprue-breakers a a¹ which
break off the sprue or jet, at same time that the two cutters a² a³ remove the fins
from the underside of the type bodies. The type-bodies having been trimmed on
the two sides, it only remains to trim them on the top and bottom faces and to form
the groove in the base. These two operations are performed simultaneously, when the
carriage E E' is in the position shewn in Figure 3 by the downward movement of
the frame K causing the screw-stud k to abut against the upper end of stem k¹ and
the type-ejectors f₁ to descend, thus pushing the types out of the jaws F into the
slots between the blocks G G' where the lateral fins are removed by the cutters g g¹
and the groove cut in the base by the cutter 92. The two types will then be finished,
and the operation is repeated on the return of the parts to the position shewn in
Figure 2.
During the injection of the metal the frame K² remains lowered and exerts
pressure upon the double carriage E E' through the screw-stud screwed into
the cross-head f" and bearing upon the plate E2 so as to hold the two top die
blocks in contact with the lateral die blocks c c. The finished types are
pushed in succession through the slots between G Ginto the guide channels h H
and are set up in line in two movable composing sticks placed at the ends of the
guides.
It will be observed that the whole of the above described operations are performed
in duplicate in the present machine, in the same manner as they are performed
singly in the ordinary single machine, the extent of motion of piston i, carriage E E¹,
matrix carriers D D', slides B B₁ and bar K', being the same as in said single
machines. This result is obtained by arranging the duplicated parts of the machine
in different longitudinal vertical planes. Thus the second mould is situated in a
lifferent vertical plane from the first one and not in the same line therewith and

page_text: similarly the part E' is in a different plane to the part E of the carriage, as shewn
in Figures 2, 3, and 4, and the matrices and injection nozzles and the blocks G G¹
are arranged correspondingly, the two guide channels H being arranged one
below and one in front of the other, in the manner of the steps of a staircase.
This arrangement in echelon of the duplicated parts enables the strokes of the
moving parts to remain unchanged and so permits of obtaining, in the same time,
two cast and finished types instead of one. Moreover it enables all parts of the
machine to be overlooked by the operator, who can thus readily superintend the
working.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1st. The herein described type-founding machine wherein the various parts for
casting, sprue-breaking, trimming, or dressing, and setting up the type, are duplicated,
as specified.
2nd. The combination in a type-founding machine of two sets of type moulds,
injection nozzles, and devices for sprue-breaking, trimming or dressing, and setting
up type, with a single set of cams and levers for operating these duplicate sets of
devices in the manner specified, so as to enable two cast and finished types to be
produced simultaneously by the same series of operations as in machines producing
a single type only.
3rd. In the herein described type-founding machine, the combination, with
a single cam shaft and set of operating cams and levers, of two sets of type-
moulds, injection nozzles, sprue-breaking, type trimming or dressing and setting,
devices arranged in echelon whereby to enable two types to be produced simul-
taneously, without increasing the range of motion of the parts, and therefore in
the same time as a single one, and to facilitate the supervision of the working
parts, as specified.
