I, EDWARD BUCKLEY, of the firm of Taylor Lang & Co Limited, of Castle Iron
Works, Stalybridge, in the County of Chester, Machine Makers, do hereby declare
the nature of said invention for "IMPROVEMENTS IN MACHINERY USED IN MAKING
MOULDS IN SAND FOR CASTING METALS," to be as follows:-
My invention consists in combinations and arrangements of mechanism-My
improved machine is formed by two side frames connected together by cross frame,
and carries two rails, upon which run flanged wheels, on two axles having bearings
in a horizontal table, which table can thus move to and fro on the said rails.
When the table is in its forward position the patterns are placed on or in the
mouldering box and the sand is filled in, the table being held in this position by a
catch that comes in a notch in its edge, which catch is withdrawn by a handle or
lever when the table is to be moved to bring the mouldering box under the
presser.
There are adjustable screw stops on the framing, to limit the two extreme
movements of the table, and act upon buffers on the table to prevent shock.
At the lower part of the framing, a shaft extends across, in suitable bearings in
the side frames, which shaft has a long lever handle at one end at the outside of
the framing by which it is oscillated-This shaft bas a boss or partial disc fixed
upon it about its middle, to which an adjustable tappet is secured, or the disc or
boss may itself form the tappet,-When the shaft is oscillated forward the tappet
comes against a bowl on a stud in a lever part loose upon a shaft, above the lower
shaft, and in bearings in the side frames.
This loose lever part swings freely forward to allow the tappet to pass, but when
the tappet oscillates back it comes against the bowl and the lever in the opposite
direction when the upper end of the lever part acts against one of the axles of the
wheels for the table, and thus moves it to the front.
The lower shaft has a lever or arm on each end at the outside of the framing,
and each arm is jointed by a connecting rod with an arm on the outer end of a
shaft, across the framing and above the table, having bearings in the side frames.
This upper shaft has a scroll or cam upon it, that acts against a roller having
bearings in a slide, arranged to move up and down in vertical guides on the side

page_text: frames It is the oscillation of this scroll or cam when the hand lever is moved
forward that moves the vertical slide and presses the sand firmly down into the
moulding box, acting upon a board or plate placed upon the sand in the moulding
box; and the back movement of the hand lever causes the vertical presser slide to
be lifted and the table to be moved back to the front.
The vertical presser slide is lifted by a spring, weight or weight lever, or by
making the pressing scroll double acting, or by a separate cam or scroll.
There is a hinged hood over the vertical presser slide, which also forms a table,
there are also sheets of thin iron to keep the sand from falling upon the moving
parts below the table.
There is also a table formed on brackets on one side of the machine for the con-
venience of the moulder.
A modification of my invention consists in dispensing with the presser slide
above the table and the shaft, and mechanism for actuating it, and making it fixed,
or adjustable in height above the table by screw or other suitable means, and in
arranging the rails carrying the table to form part of a frame so as to move
vertically in suitable guides on the framing.
The scroll cam or other mechanism in this arrangement is placed on the lower
shaft, and acts upon a bowl in the frame for the rails so as to lift the rails and thus
the table bodily and consequently the moulding box upon it, to force it up against
the fixed presser or surface above the table-The tappet on the lower shaft is made
to act upon a bowl in an arm on the shaft above, and an arm from the latter acts
upon the carriage of the table.
A lever on the lower shaft connected with an arm on the shaft above and a
catch rod jointed to another arm on the second shaft is or may be used in place of
the tappet and lever mechanism and made to act on the table to move it forward
when the mould has been pressed and the lever handle is moved backwards, and a
cross shaft in bearings in the framing and lever handle upon it, is or may be used
for releasing the catch rod from the table when it is to be moved back to bring the
nould box under the presser.
A catch lever jointed to the table may be used in place of the catch rod, one end
of the catch lever being moved when the table is to be moved under the presser.

for Casting Metals.
I EDWARD BUCKLEY of the firm of Taylor Lang & Co Limited of Castle Iron
Works Stalybridge, in the County of Chester Machine Makers, 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 consists in combinations and arrangements of mechanism-My
improved machine is formed by two side frames connected together by cross frames
and carries two rails, upon which run flanged wheels, on two axles having bearings
in a horizontal table, which table can thus move to and fro on the said rails.
When the table is in its forward position the patterns are placed on or in the
moulding box and the sand is filled in, the table being held in this position by a
catch that comes in a notch in its edge, which catch is withdrawn by a handle or
lever when the table is to be moved to bring the moulding box under the presser.
There are adjustable screw stops, on the framing to limit the two extreme
movements of the table, and act upon buffers on the table to provent excessive
shock.
At the lower part of the framing, a shaft extends across in suitable bearings in
the side frames, which shaft has a long lever handle at one end, at the outside of
the framing, by which it is oscillated-This shaft has a boss or partial disc fixed
upon it about its middle, to which an adjustable tappet is secured, or the disc or
boss may itself form the tappet-When the shaft is oscillated forward the tappet
comes against a bowl on a stud in a lever part loose upon a shaft, above the lower
shaft and in bearings in the side frames.
This loose lever part swings freely forward to allow the tappet to pass, but when
the tappet oscillates back, it comes against the bowl and oscillates the lever in the
opposite direction when the upper end of the lever part acts against one of the
axles of the wheels for the table, and thus moves it to the front.
The lower shaft, has a lever or arm on each end, at the outside of the framing
and each arm is jointed by a connecting rod with an arm on the outer end of a
shaft, across the framing, and above the table, having bearings in the side frames.
This upper shaft has a scroll or cam upon it that acts against a roller having
bearings in a slide arranged to move up and down in vertical guides on the side
frames-It is the oscillation of this scroll or cam when the hand lever is moved
forward that moves the vertical slide and presses the sand firmly down into the
moulding box, acting upon a board or plate placed upon the sand in the moulding
box, and the back movement of the hand lever causes the vertical presser slide to
be lifted and the table to be moved back to the front.
The vertical presser slide is lifted by a spring, weight, or weight lever, or by
making the pressing scroll double acting, or by a separate cam or scroll.
There is a hinged hood over the vertical presser slide, which also forms a table,
there are also sheets of thin iron to keep the sand from falling upon the moving
parts below the table.

page_text: There is or may also be a table formed on brackets on one side of the machine
for the convenience of the moulder.
A modification of my invention consists in dispensing with the presser slide
above the table and the shaft and mechanism for actuating it, and making it fixed,
or adjustable in height above the table by a screw or other suitable means and in
arranging the rails carrying the table to form part of a frame so as to move
vertically in suitable guides on the framing.
The scroll, cam or other mechanism in this arrangement is placed on the lower
shaft and acts upon a bowl in the frame for the rails so as to lift the rails and thus
the table bodily and consequently the moulding box upon it, to force it up against
the fixed presser or surface above the table-The tappet on the lower shaft is made
to act upon a bowl in an arm on the shaft above, and an arm from the latter acts
upon the carriage of the table.
Fig. 1 is an end elevation, fig. 2 a front elevation partly in section, and fig. 3 is
a longitudinal elevation partly in section, illustrating one modification of my
invention.
Fig. 4 is a front elevation and fig. 5, a longitudinal elevation partly in section
showing another modification of my invention.
Fig. 6 is a partial longitudinal elevation in section illustrating a modification of
the machine shown by figs. 1, 2 and 3.
In the modification shown by figs. 1 2 and 3; a are the side frames; a¹ the
cross rails, the ends of which are secured to the side frames.
b are two rails passing longitudinally the ends of which are secured to the two
upper cross rails a.
Upon these rails b, flanged wheels b₁ on two axles 62 run, which axles have their
journals in sides bs descending from a table b which can thus be readily moved to
and fro on the rails 6 the table 6* being shown in fig. 3 moved to the front of the
machine, the table b then projecting over the end framing.
On each side and on each end of the table, under it, a rib 6 is attached or
formed, which at each end is bored out to receive a buffer or piston pin 6º, part of
its end projects from the rib and the other part within the hole is reduced to form
the piston rod and has a series of small india rubber rings and thin metal washers
placed upon it which will be compressed and act as a buffer when the large or
projecting end is driven in, as when the table is moved to either extreme, when the
ends of the buffers will come against the ends of adjustable set screws 67 screwing
through parts projecting from the side framing.
There is a catch or latch (not shown) which is acted upon by a spring or may be
otherwise arranged to automatically enter a notch in the edge of the table when
moved to its extreme position shown in fig. 3-This catch is withdrawn by a handle
when the table is to be moved to bring the moulding box under the presser;
68 is a part in the middle of the widthway of the table 6 and secured thereto by
set screws passing through slots so that it can be adjusted in the direction of the
lengthway of the table.
This stop 68 is a guide for the moulder to push the box against when placed on
the table, so that when the latter is moved forward, it will come exactly under the
presser,
o is a shaft in suitable bearings on the side frames, which shaft is actuated by
a lever handle c¹ which is or may be arranged so as to be adjustable on the shaft to
bring the upper end of the handle more or less forward, and is then secured
to a segmental part c³ keyed or otherwise secured on the end of the shaft c.
On the shaft c a disc c is secured to which a tappet c is attached so as to be
adjustable, this tappet will act upon a bowl c³ on a stud in a weight lever c loose
between fixed collars on a shaft c' having bearings on the side frames.
The lever is of the shape shown, or of any other shape which will give weight
to keep it in the position shown in fig. 3 when it is free and not otherwise acted
upon except by gravity,

page_text: The upper part of the weight lever c has a thin piece of flexible steel c³ bolted
to it.
When the table b' is moved to bring the moulding box under the presser the
axle be nearest to it as shown in fig. 3, comes against the steel projection and the
lever cswings to one side to allow it to pass, and then assumes the vertical position
again.
When the shaft c is oscillated to give tho pressure, the tappet c* first comes
against the bowl cas shown in fig. 3, and oscillates the lever and passes the bowl,
but when the back oscillation takes place after the pressure has been put on the
sand, the tappet e then acts upon the other side of the bowl c and moves the
lever c in the reverse direction when the steel blade c8 comes against the axle b²
nearest the front of the machine and moves the table b' to the position in which it
is shown in fig. 3.
Side frames a* are secured on each side above the level of the table, in the inside
of which slideways or guides are formed for the presser slide d which moves up and
down vertically.
A shaft has bearings in the side frames a* to which a scroll or cam d² is
secured which acts upon a steel roller d³ carried on the slide d.
The slide d is held up to the cam d² by a bent spring done end of which comes
under a loop 5 formed at the upper edge of the web of the slide d the other end
is attached to a cross bar a secured between the side frames.
There is an arm de secured on each end of the shaft d'and each arm is jointed
to one end of a rod d' the other end of which is jointed to an arın c³ on the shaft c
so that both shafts c and d oscillate together.
There is a cover or hood e made of thin sheet iron hinged to the framing at c¹,
this hood forms a shelf and prevents sand from getting upon the moving parts.
The sheet iron cover may also project downwards from the hood e in front to
about the level of the upper face of the presser when up.
A thin sheet of iron e may also be attached to the table to prevent sand from
getting to the parts within the framing.
In the modification shown by figs. 4 and 5, a is the side framing connected by
cross rails not shown.
There is a frame having two sides f1 for the wheels of the table b to run upon
these rails being connected at the two ends by cross bars f².
The frame has two descending projections f³, having slots for two shafts c and c
to pass through, which shafts have bearings in the main side frames a.
The shaft c in the lower vertical slots guides the descending projections f³ in
their vertical movements.
There are also projections f'on each side of the frame, which slide between guide
ribs a³ on the insides of the main framing.
On the shaft c, a scroll cam d³ is secured which acts against a bowl f5 on a rod
extending through bosses, from the descending side frames f³.
On the shaft c7 an arm co is secured to which a steel blade c is attached which
acts to move the carriage as herein before described in reference to figs. 1, 2 and 3.
To the same shaft cat one side, another arm c* is secured carrying a bowl c
acted upon by a tappet or arm c* secured on the shaft c.
The arm cor arm c* or both are weighted to keep them vertical when not
otherwise acted upon as explained in reference to figs. 1, 2 and 3.
It will be understood that when the handle c¹ is oscillated one way the scroll
cam d³ will lift the frame and table 6, and force the sand in the moulding box
against the fixed presser d.
This presser is or may be made adjustable vertically by a screw, screws or other
suitable means.
Fig. 6 illustrates a modification of the machine shown by figs. 1, 2 and 3.
The table b' is arranged and acted upon as described in reference to figs. 1, 2
and 3- is the shaft in bearings in the side frames; the lower shaft.

page_text: The presser d in this modification is attached at each end to two descending
broad bars de (inside or outside the side frames) which are each arranged in vertical
guides formed by ribs at on the top and bottom of the sides of the main framing a.
There are slots in each bar d to give space for the shaft c to pass through.
On the lower shaft c an excentric d' is formed or fixed at each side and acts in
a horizontal slot in the lower part of the bar d³.
When the shaft c is oscillated one way the bars da and thus the presser dis
drawn down; and when moved the other way the presser d is lifted.-Cams, scrolls
or cranks may be substituted for the excentric and when single acting cams or
scrolls are used a weight lever is or may be used on each side to lift the bars and
presser, and keep it against the surface of the cam or scroll.
The presser is or may be arranged to be adjustable vertically by a screw, screws
or other suitable means.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed,-I declare that what
I claim is
1. The combination of mechanism by which the handle when moved one way to
give the pressure upon the sand, will when moved the other way bring the table
to the front substantially as hereinbefore described and illustrated by the drawings.
2. The combination of mechanism substantially as and for the purpose herein-
before described and illustrated by figs. 1, 2 and 3 of the drawings.
.
3. The combination of mechanism substantially as and for the purpose herein-
before described and illustrated by figs. 4 and 5 of the drawings.
4. The combination of mechanism substantially as and for the purpose herein-
before described and illustrated by figs. 1, 2 and 3, when modified and combined
with the mechanism hereinbefore described and illustrated by fig. 6 of the drawings.
5. The combination and arrangement of a movable table, a presser for acting
upon the sand, and the mechanism for acting upon the presser, substantially as
herein before described and illustrated by figs. 1, 2 and 3, figs. 4 and 5 and figs. 2
and 3 and fig. 6 of the drawings.
