Improvements in Moulding Machines.
LEWIS EDWORTHY, of the City of Hamilton, in the County of Wentworth,
in the Province of Ontario, Dominion of Canada, Pattern Maker, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in moulding machines consisting of a
combination of several parts of mechanism for the purpose of making moulds for
all manner of castings, consisting for example of stove-plate, hollow-ware, pipes
and castings in general. The objects of my invention are, first, to provide a
moulding machine which is capable of producing moulds from patterns with a
minimum of manual labour.
Second, to afford facilities for the proper and complete production of the same
in a thorough and superior manner than is possible to accomplish by hand labour,
third, to accomplish the moulds for castings in a manner that will reduce the cost
of production to a very large degree, and fourthly, to provide an automatic
machine that is self-adjusting for all manner of work.
The general and stove castings-moulds are provided, by means of a case having a
series of pneumatic tubes on a frame-work, which operates and controls a series of
self adjustable rammers, which are supplied with sand by seives rotating over
hoppers, operated and controlled by air cushions contained in the aforesaid
tubes.
The work at this stage then proceeds automatically to be operated upon by
mechanism which adjusts the bottom boards and presses moulding sand to an even
surface. It is then automatically transferred to another part of the machine for
venting, gate-cutting, and application of parting-sand, proceeding then to another
part of machine where the cope is removed, patterns drawn, facing applied, pattern
printed and then removed.
After this the cope is readjusted which completes the process.
This process can be applied to two, three, or four ply boxes.
Hollow-ware and all kinds of pipe moulds are produced by means of a
combination of rotary sand rammers operated by special mechanism adapted to
that purpose, and guaged in such a manner that the said rammers may exert a
proper and definite pressure upon the sand of the moulding box.
The above mentioned rotary seives are supplied with sand by means of elevator
buckets which convey the sand from a cylinder in which it is mixed, sifted and
cooled.

Improvements in Moulding Machines.
I LEWIS EDWORTHY, of the City of Hamilton, County of Wentworth,
Province of Ontario, Dominion of Canada, Pattern Maker, 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 machine which operates on the knowel or drag, the other half of the machine,
or cope side, is similar in almost every respect. The cope undergoes almost the
same operation as the knowel or drag, but any difference that may exist will be
shown in the vertical transverse sections, (the knowel or drag is the bottom half of
a flask, the cope the top half, the two constitute a flask).

the platen, according to the nature of the work, the sprue or gate when required is
placed in position in this section.
Fig. 7, is a vertical transverse section on the line 9 and 10, showing the mechanism
for venting the mold in the knowel, and for sometimes cutting the sprue holes in the
cope, also for turning the knowel or drag upside down and onto the return track,
when the follow-board is removed and the cope placed on the knowel.
Fig. 8, is a vertical transverse section on the line 11 and 12, showing the
mechanism for lifting the cope from off the knowel, drawing the pattern and printing
the same back into the mold, the facing is applied by the attendant; the cope is
again lowered on the knowel, the flask moved to the end of the machine and
onto a truck, by which it is carried to the cupola, or some convenient place for
pouring off.
The work in Fig. 8, briefly described, must be done slowly to guarantee
satisfactory results, I purpose having one or more similar sections or parts for doing
the same work, all working in regular order with each other, so that the work may
be done expeditiously and without hindrance to the output of the other parts of
the machine, in the drawings four of those sections are shown,-the one Specification
refers to the four.

The machine as described is a double machine, one side for the knowel, the other
for the cope and for general purposes, the same may be made single for the same
purpose, or it can be built in many forms for special work.
In describing the machine in detail, similar letters refer to similar parts
throughout.
In the drawings, A is the frame which will be substantially constructed of iron,
or other suitable material, to resist the strain and vibration of the operating parts,
B is the driving pulley; B' is a loose pulley on the shaft C. from which motion is
communicated to the operating parts. A' are rollers whose periphery is in a line
with the tracks A³, A³, A', A³, on these rollers the flasks are moved along the front
of the machine to their respective places. For want of space in drawing, the rollers
have been moved under the duct A°, as shown in Figures 1, 2, 4. A is the track
over which the knowel or drag passes to Fig. 7; here the knowel is turned over on
the side track A³, when the follow board is removed, and the cope placed on the
knowel or drag, A' is the track over which the flasks pass into Fig. 8, A' is a
return track, but only used when working with three or four part flasks.
A and A are cables passing around the guide sheaves a-a and around
the sheaves A and A, on the shaft B2, which gives motion to the cables A'
and A, - are anti-friction rollers on the ends of the shafts B³, which
carry the pawls c-c, and which engages with the flask and propels the
same through the different stages of operation. a' is a frame for keeping in
position the shafts B³, to which shafts the cables A7 and A8 are secured
by the sleeves B, B is a bevel wheel gearing with the bevel pinion B on the
telescope shaft B'. On the upper end of this shaft is a similar pinion 13 gearing
with the bevel wheels B and B10, which are loose on the shaft C. Between these
two wheels is the sleeve C³, (Fig. 7) sliding on and revolving with the shaft C¹.
In this sleeve is an annular groove, in which works the ring C³, pivoted to the
arm C, this arm is also pivoted on the frame A at C³, the other end engages with
the cam C, this cam gives the arm C the required side motion to clutch the
sleeve C, alternately with the wheels B' and B, thus giving a reciprocating
motion to the cables A' and A³ for moving the flasks to their respective places
whilst undergoing the different operations, the sleeve C³ is serrated on the two sides,
and the bevel wheels B and B serrated to match, C' Fig. 14 are pinions
on shaft C, gearing with the spur wheel CB, on the shaft C, C are pinions on
the shaft D, and gearing with the spur wheel C and D1, D2 is a spur wheel on the
shaft I), gearing with the piniou D³ on the driving shaft C, thus conveying motion,
through the aforesaid wheels and pinions to the cables A' and A8, for moving the
flask as above described.
Fig. 4, on section line 3 and 4, D' are the elevator buckets or scoops, secured to
the chains D passing around sprocket wheels which are supported on the
brackets D; D' are pulleys for putting the same in motion, receiving power from
a countershaft in proximity with the machine (not shown), the tempered sand is
carried by those buckets from the floor, or from a receptable in the floor, up to the
chute board D, which conducts the sand into the revolving sieves D³, these sieves
being on an incline the sand spreads throughout the whole length and is sifted onto
the vibrating sieves D1 and onto the chute board or apron E, the vibrating
sieve: Do spreads the sand evenly over the patterns, D are eccentrics on the
shaft G; D eccentrics rods in which is a notch engaging with the pin D¹³ on the
lever pivoted at D; the end of this lever is also pivoted to the sieve D¹º to which
it gives a vibrating motion. If at any time there should not be a flask under the
sieve Do, the wheel at drops and carries with it the eccentrics rod D12 which releases
the lever and pin D13, stopping the sieve D1, on this sieve the sand from the
revolving sieves lodges until another flask comes into position. The chute board
or apron E conveys the sand to the vibrating and inclined sieve E', which

page_text: distributes the sand in the knowel or drag, and in the cope the second time, filling
up all cavities and inequalities in the mold caused by compressing the sand in the
first operation. E' are cross heads shown on plan and in Figs. 2 and 4 and in
detail Figs. 15 and 16. E are cranks keyed to the shaft E and E°. E' are the
crank pins working in the sliding block E7, Es are girder irons firmly secured to
the crossheads E', forming a rigid frame to which is secured the iron plate E', Fig. 16.
E is a strip of packing around and even with the edges of the plate E and
forming a space between the plate E and a diaphragm F. This diaphragm of
rubber or other flexible material covers the plate E on the lower side and has
around its lower edge a strip of packing F¹, similar to E and forming a space
between the diaphragm F and the plate F, through this space the cylinders have
communication with each other. The plate F' and the packing F³ in which the
cylinder ends are bedded, have small aperatures F, about the center of each
cylinder, thus making the connection through which the pressure is equalized in
each and every cylinder, the plates and packing are closely bolted around the
edges, over the cylinders are the plugs aa² fitting in corresponding holes in
the plate E' used only to press the diaphragm on the aperature F, and close the
same when testing the cylinders in case of a leakage. The piston sliding in the
cylinders G, and the angular piston rods F working in corresponding holes in
guide plates F, Fa piston head secured to the piston rod, this constitutes the
rammers or pressure pistons, and when lowerd down on the work by the aforesaid
cranks adjust themselves to any form of mold and gives an equal pressure to all
parts, the outside piston heads next to the flask and next to the bars, have a third
or more of the piston head cut away, presenting less surface to the sand and giving
more pressure per inch, to overcome the friction between the sand and flask when
being forced down by the pistons, and also for giving more compactness to the
sand in the joint of the mold.
on
F is a valve to guage the pressure on the pistons. F10 is a valve for admitting
into the cylinders G, air, water or other fluids through a flexible tube G₁ from a
tank or reservoir in close proximity to the machine (not shown) containing fluid
under pressure, the supply being kept up by the pumps G; (Figs. 3-and 8).
G-G are slots in the crossheads guiding the same vertically over the
shafts E and E³, and keeping the frame in a horizontal position. G a frame
supporting the cylinders G in position and sliding in guides in the frame A as
shown in Fig. 16. G³ a heavy sprocket wheel on the driving shaft C around which
passes a chain conveying motion to a heavy sprocket wheel on the shaft G', on
this shaft are the pinions G8 gearing with the spur wheel G, on the shaft Go,
this shaft are the pinions H gearing with the spur wheels H' and H2, on the
shafts E and E to which is keyed the cranks E³, the pins of which engage with
the sliding block E', thus giving a reciprocating motion to the frame supporting
the cylinders and pistons, which constitute the rammers as before described.
chute board E and the sieve E' are vibrated by the eccentrics H³, on the shaft C,
shown on plan Figs. 5 and 14, the eccentric rods are pivoted to the arm H*, these
arms slide on the vertical shaft. H' to which they give a reciprocating motion.
At a are similar arms to H' shown by dotted lines sliding with the frame S and
pivoted to the sieve E, thus giving a vibrating motion to the sieve and distributing
the sand evenly in the flask. The belt pulleys H-H' on the shaft which
carries the revolving sieves D, two of these over the vibrating sieves D10 receive
motion from the driving pulley H', the two sieves over the chute board E are put
in motion by the driving pulley H³ in Fig. 6. When making hollow-ware or pipes
the rotating sieves may be placed one over the other on the front and back of the
frame A Fig. 5.
The
Fig. 5, S is a frame sliding in the main frame A, for lowering and raising
the rammers out of the mold, and to which frame is journaled the shafts S
On these shafts are the eccentrics S, which gives a reciprocating motion to the
rammers S³. The eccentric rods is journaled to the shaft 2,63 is a sleeve

page_text: through which the shaft 6 passes, and to which the vertical shaft is journaled,
is an arm secured to the vertical shaft on which are placed the rammers S³,
held in position by set screws or other means. S is a shield or guage carried
by the arms 68 in front of the rammers, to guage the depth of sand necessary in
making molds. 6 and bare sleeves journaled in the frame S and through
which slides the vertical shaft b. To the sleeve are fastened the arms 1,8
carrying the guage S. 6° and 610 are pawls engaged with the ratchet wheels c
and c forming a part of the sleeve and . These pawls are held in position
by the springs c (Fig. 13).
c is a spiral screw sliding in corresponding threads in the sleeve U, the above
operates as follows:-The eccentrics S2 revolving with the shaft S¹ gives the vertical
shaft (to which is attached the rammers S³) a reciprocating or up and down
motion. The shaft is connected with the eccentric by the rods 6', the shaft b² and
the sleeve b. The revolving of the rammers is caused by the action of the spiral
screw and the sleeves 6 and 7, the vertical shaft in its upward motion is forced
around by the action of the spiral screw sliding in corresponding threads in the
sleeve b', carrying around with it the rammers S³, the guages S, and the sleeve be
to an angle of about 30 degrees, when the pawl 6 again engages with the ratchet on
the sleeve, and holds the same in position until the next up stroke of the shaft b*.
The vertical shaft being angular in the sleeve 6º, causes the rammers to decend
vertically, and turns the sleeve around to about the same angle as above mentioned.
S is a driving pulley on the shaft C, conveying motion to the pulleys S', on the
shaft S, and to the eccentrics S2, by which a reciprocating motion is given to the
rammers as before described. The belt for putting the aforesaid in motion passes
around from the driving pulley S, to and over the loose pulley 8, down and around
the tight pulleys S7, over the adjoining pulley S7, then down and under the loose
pulleys at the bottom of the frame, and over the loose pulley co to the place of
commencement. The belt is carried around in this form so that the frame S, in its
up and down motion will not affect the tension of the belt. The pulley elo is snown
in dotted lines in Fig. 2, its proper place being taken away by breaking the frame A.
In Figs. 12 and 13 is shown the mechanism for starting and stopping the
different parts automatically. Pivoted to the shaft H, and between collars held in
position by set screws are the arms and d, the arm should be placed high
enough on the shaft H' so that the rammers S³ may be clear of the mold when the
frame S engages with the arm d. d³ and d are arms pivoted between the collars
on the shaft H, carrying the rods d', on which are the collars d and do, and the
spiral spring 10. el is a pawl engaging with a ratchet wheel e and pivoted to the
eccentric rode. et is an eccentric on the shaft C, which gives motion to the drum es,
over this drum passes the cable or chain for lowering and raising the frame S. eis
a pawl for holding the drum e in position, when the pawl e' is released. is an
arin engaging with the wheel es, this arm is held in position by the spring . eo is
a projection on the wheel es, for pressing down the lever e' to release the pawls e
from the drum and ratchet wheel e, which lowers the rammers in the mold. The
spur wheel & engages with a spur wheel, on the shaft C". is a pawl sliding on
the bar, and to which it is bolted; an anti-friction roller pivoted to the
disk; a shaft to which the disk fand the arm are keyed; 8 a lever for
carrying a weight. The above operates as follows:-The frame S in its upward
motion brings the pawl fin contact with the anti-friction roller 3 which turns the
weight over and clutches the driving shaft C with the pinion D³, as shown in
Figs. 6 and 14, giving motion to the mechanism in Figs. 6, 7 and 8. About the
same time as the pawl comes in contact with the anti-friction roller f³, the
frame S comes in contact with the arm d on the shaft H (Fig. 12), carrying up
with it the arms d³ and d³, closing the spiral spring do, lifts the rod d' with the
collars and which releases the pawl e from the ratchet e², and stops the up
motion of the frame S, and which is now held in position by the pawle, the raminers
now being clear of the mold, the flask is moved forward into Fig. 6 for the next

page_text: operation, by the mechanism of the cables A' and A³, as before described, and
another flask is brought into Fig. 5, then the projection on the wheel e comes in
contact with the lever e', and releases the pawle from the ratchet wheel e*; the
bent lever is then forced by the spiral spring 10 in front of the pawl e thus
preventing the same from engaging with the ratchet wheel, until the rammers
have been lowered down in the mold, when the frame S again comes in contact
with the arm d³ on the shaft H, and draws down the arms d³, do and the bent
lever, releasing the pawl e, when it again with the pawi e' engages with the
ratchet wheel and carries the rammers upwards, as the work proceeds, the weight
and lever being thrown over to its first position by the cam S acting again the
arm 10, releasing the clutch from the pinion D³, stopping the mechanism in
Figs. 6, 7 and 8, as before described. In making water pipes or other deep molds,
the machine would be set over a well or pit, the depth of which would be equal to
the length of the flask; the tracks A3 and A' would be lowered to the bottom
of the pit, and the flask moved over the same by the cables A and A°; the
rammers would be lengthened to the depth of the mold and would work inside of
the pipe or cylinder T, shown in dotted lines in Fig. 5; the pipe is somewhat
larger than the patterns and forms a guide to the rammers. Fig. 6 on section
line 7 and 8, H is a bottom-board placed on the supports H10, the same being part
of the sliding rod I, shown on plan and Figs. 6 and 7, and which are journaled in
the sleeve I and in the frame A. 12 is a shaft passing through the sleeve I', and
journaled to the arm 13. 1 is a bracket bolted to the frame A, and supporting the
arms 15, in Figs. 5 and 7, and 1' and 16 in Fig. 6. 17 is a shaft journaled in the
bracket 1, to which the arm 1' is keyed, I is an arm hinged to the bracket I*,
Fig. 6, the upper ends of the arms I and I are hinged to the plate 1', carrying
the anti-friction rollers K', Figs. 6 and 7. At 10 the plate 1 and the arm I are
hinged to the arm 13; and in Fig. 5 only the arm 1 is hinged to the arm 13;
at K the arm 13 is hinged to the arm K', the same being hinged to the frame A.
The anti-friction rollers K* engage one on each side of a raised flange K³ around
the periphery of a wheel forming the cam K, the action of which when revolving
forces the arms with the bottom-board, as before described, in over the knowel or
drag and deposits the same on the sand, and returns to its first position. K' are
eccentrics on the shaft C' and C in Figs. 1, 5, 6 and 14, K are eccentric rods
having bearings on the bars K', the ends of which slides in grooves K8 in frame A,
K are pillow-blocks to which are firmly secured the bars K', the angle irons L,
and the girder irons L', also the cross bars L³, forming a rigid frame, having on
its lower side platens or dies L³, made portable, so that suitable dies may be used
for certain kinds of molds, for example see Fig. 23; p is a section of a die as used
when making holloware. L' are rods sliding in stediments, d-d being a part of
pillow blocks K', L' are levers pivoted to the pillow block at ff; the ends of
these levers have slotted holes, one end of each lever engages with the rod L*; the
other end of one pair works on a pin at g on the frame A; the other pair engages
similarly with the bar 18, and which operates as follows:-
The bottom board being placed in position, as before stated, is forced down
into the knowel by the actions of the eccentrics on the platen, until the hooks L
engage with the catch e, the hooks are forced from a horizontal to a vertical
position, by the actions of the rods L, the levers L, and the platen L³, as before
described. On the cope side of the machine the platen may be plain or otherwise,
according to the class of work; in making stove plates or other light castings,
adjustable flat sprues would be carried in over the cope and under the platen by
arms similar to those already described in I to K'; the platen forces the same
down into the sand, and the sand in the cope around the sprue, making the
necessary sprue boles for the molten metal. In making hollow-ware or castings
requiring three or four part flasks, the die p for making the joint in the mold, is
carried in over the patterns by similar arms to those already described, and is
pressed down on the mold by the eccentrics and platen, when it is again lifted up

page_text: and withdrawn by the aforesaid arms, leaving the flask ready for the cope. Flasks
of the above description would pass through the section of the machine alternately,
one with the cope, the next without the cope; the die p would only be brought into
use for every second flask. To arrange for this the cam K on the right clutches
with the spur wheel D', every second round, regulated by the action of the pawl
and pin a shown in dotted lines in Fig. 6. Fig. 7. on section line 9 and 10,
L are wires for venting the mold, to let the gasses formed by the molten metal
escape, these wires also form the piston rods to the pistons working in the
cylinders L. These cylinders and all the connections thereto are similar in
every respect to those already described in Figs. 2 and 4, from E to F, and
from F10 to G2, in place of a piston head F being attached to the end of the
rods, the rods are pointed so as to penetrate the sand more easily when venting the
mold. Lo are cross heads similar to those in E2, and having a sliding block M,
carrying the crank pin M', M² a disk in which the shafts C¹ and M³ revolve, M* is
a disk forming a part of the sleeve M in which is an annular groove M, revolving
in the ring M', the same being pivoted to the arm M³, M a shaft to which the
arm M is keyed; the arm M10 is also keyed to the same shaft in Fig. 6, the
end of which engages with the cam N and through which the disk M³ clutches
and unclutches with the crank pin M¹, giving the aforesaid mechanism the
necessary vertical or up and down motion for venting the mold, and for cutting
the sprue holes in the cope; at the same time the wires are venting the mold, the
cam Kforces the arm I3 with its connections as described in Fig. 5 (and shown
broken in Fig. 7), into the machine, when the arm a engage with the trunnion a
and draws the knowel outward until the wheel as (shown in dotted lines) engage
with the rack a which causes the wheel to turn over, turning with it the knowel
and leaving it on the return track A³, when the follow board is removed, the mold
dressed and the cope placed on the knowel by the attendant. - are augers.
for cutting round sprue holes in the cope and to which a revolving motion is given
by a belt passing around the sheaves i-i, N is a tube on the bar N'; N a tube
on the bar N', through which the tube N slides cutting its way through the sand
to a set gate in the mold, the sand in the tube being removed by the augers and
carried up into a box or trough, through which the sand is conveyed back into.
section 5, where it drops into the flask.
On the cope side of the machine the arms a draws the flask on the rollers from
the track A to track A to be returned to the front, for the second operation;
this is only done when working three or four part flasks, or when the flasks are
of unusual depth. V are arms releasing the hooks L, on the cope before passing
into the next section. Fig. 8, on the section line 11 and 12 are four similar sections
or parts, for doing similar work. Fig. 9 is a plan of one of the sections, and one
Specification describes the four. N are mitre wheels on the shafts M³ and No,
giving motion to all the sections, O is a worm or screw wheel engaging with the
cam 0, which regulates the movements of the flasks. Through the action of
the levers k, pivoted at k¹, the rod k³, the arm A, which is keyed to the rocking
shaft, on this shaft is also keyed the arm ko, the end of which engages with
the sleeve 0, and which revolves with and slides on the shaft M; the same
clutches with either of the bevel pinions 0³, and which reverses the motion of
the flask according to the position of the cam O'. O is a bevel wheel gearing
with the bevel pinions 03, and keyed to the shaft 0; 0' a sprocket wheel
clutching with the bevel wheel O', from this sprocket wheel motion is given to
the sprocket wheel 07 on the shaft 08, on these shafts are the sprocket wheels.
and rollers 0, over which the chains m' pass for carrying the flask. P is an
extension shaft on each side of which is a bevel pinion P1 gearing with the bevel
wheels P2 and P3. P are sprocket wheels (shown in Fig. 3, broken) over which
pass the chain P, this chain moves the flask from about the line of the shaft P
to either of the four sections, or onto a car at the end of the machine, which
carries the flask to the cupola, or to some convenient place for pouring off, when
the flask is left on the rollers m and the chain m¹, the cam O' through the levers

page_text: l
and arms from k to k³, clutches the sleeve O with one of the bevel wheels O
giving motion to the sprocket wheel and chain m¹ which carries the flask outwards
and brings the same in contact with the arm P, forcing the same over until the
trunnions on the cope engage with the sleeve Q and m³, on the bar mo. The
same time as the arm P is being forced over it lifts the rod P' and the link P³
upwards and throws the weight over to the side shown in Figs. 8 and 9, the
arms acting against a projection on the link P8 clutches the disk P' with the spur
wheel P10, thus giving motion to the crank disk m', which being connected by the
sleeve Q by the rod Q' lifts the cope upwards until the oblong pin m², on the bar m",
touches the top of the slot m8 which turns the cope to a vertical position as shown
at Q3, m is a break for holding the cope in a horizontal position until the pin m
comes in contact with the top of the slot m³. About the time the cope commences
to turn to a vertical position the stud m³ on back of crank disk m' engages with the
pawl on the arm 1 turning the weight over to the other side, and releasing the
link P, when it with the rod P' and the arm P returns to their first position,
the weight being thrown over clutches the sprocket wheel O' with the bevel
wheel O, thus again carrying the flask outwards and forcing the lever P over
which again throws the weight over by mechanism similar to that before described
(from P to P) clutching the disk R with the spur wheel R' giving motion to
the crank disk R, the same being connected to the sleeve Q7 by the rod Q, and
which lowers the frame R and the grips n onto the patterns; the rods n sliding
in the frame R Fig. 10 comes in contact with the flask and releases the pawls n'
from the grips n which now adjust themselves to the patterns in the mold; the
frame R being again drawn upwards the rods n goes back to their first position
and engage with the pawls n' with the grips n the same engages with and lifts the
patterns out of the mold; the sleeve Q coming in contact with the spiral sleeve R'
swings the frame R around to about 45 degrees; at the same time by the action
of the pin n° and the slot no the frame R is turned up in a vertical position for
inspection by the attendant, the stud on the back of the crank disk Re turns the
arm with the weight up vertically, and holds the same in position until the
attendants have examined the cope and knowel and applied the facing, the weight
is again thrown over by the attendant pressing the handle R which clutches the
disk R with the spur wheel R giving motion to the frame R as before, and
printing the patterns back into the mold, withdrawing the same and swinging it
around to an
angle as above described, the patterns now being taken away by the
attendant. Figs. 1 and 3 a fan to which is attached flexible tubes for the use of
attendants in cleaning and sprinkling the mold; a countershaft and pulley,
driving pulley for the same, also forming a part of the friction clutch. The stud
on the back of the crank disk R engages with a pawl on the arm and releases the
link P, again throwing the weight over, which clutches the sprocket wheel 0° to
the bevel wheel O', whose motion is now reversed by the action of the cam 0¹
sliding the sleeve O to clutch with the opposite bevel pinion 0%, the sprocket
wheel O and the chain m¹ being also reversed the knowel or drag is carried
inward releasing the aforesaid arm, comes in contact with the arm P which forces
the same over and lifts the rod P7 and link P8 thus throwing the weight over
and clutching the disk P with the spur wheel P10 as before mentioned which gives
motion to the crank disk lowering the cope onto the knowel or drag; the oblong
pin m when at the top of the slot locks the arm m³ so that the cope is brought
to a horizontal position before being lowered onto the knowel. The lever and
weight is again thrown over and clutches the sprocket wheel O to the bevel
wheel O, giving motion to the sprocket wheel O and the chain m¹ which carries
the flask onto the rollers m and the chain P, the hooks y, on this chain engage
with the flask and propels the same onto a truck which carries the flask to the
cupola or some convenient place for pouring off. When a flask has been completed
in either of the sections and is being moved to a truck the chain P³ engages with
another flask from where released by the cable A and drawn forward onto the
chain m' and the rollers m leading into that section from which the completed
a

page_text: flask has just been removed. Fig. 21 is a section and Fig. 22 is a plan of chain,
9 are the links, gare the hooks for propelling the flask; are anti-friction
rollers pivoted to the hooks; g are bars having recesses in which the hooks drop
when releasing the flask; there are two of these bars and two lines of hooks, so
that when a hook first engages a flask, it is propelled into the first section of
Fig. 8 and on the rollers m and the chain m¹: the hook then drops into a recess
iu the bar, and which extends to about the middle of the second section of Fig. 8,
when the bar again lifts the hook up so as to engage with any flask that may
have been finished, and carry the same onto a truck at the end of the machine, as
before mentioned. The second line of hooks engage with the flask when released
by the cable A8 and is carried onto the rollers m and the chain m¹ in the second
section of Fig. 8, when the hooks drop into a recess and releases the flask, the
chain m' engages the flask and carries it into a section from which a finished flask
has been taken and carried onto a truck, as before mentioned. When a flask is
finished in either of the sections and returned back on the chain P' the same carries
the flask from the first section into the second, and from the second section onto a
truck which carries the flask to the cupola, as before mentioned. T' Figs. 2, 4
and 6 are beams pivoted to the beams T, the same is pivoted to the beams T" the
ends of those bars are pivoted to the rods T', the same passing through the beams T
as shown in Figs. 15 and 16, supporting a platform composed of the levers aforesaid
mentioned, To a cam which raises the platform up under the follow-board or bottom-
board and support the same when under pressure, either when the sand is being
compressed by the rammers or compressed by the bottom board or platen, V₁ are
screws for adjusting the heighth of the tracks for any depth of flask. Deep flasks
should pass through the machine two or more times before having the bottom board
placed on the knowel.
