The object of my invention is to construct a new and improved hydraulic
machine. The machine may be used for making bricks paving-blocks, coal-blocks,
tiles and other similar pressed manufactures.
The nature of my invention consists in the improved mechanisins forming my

page_text: machine, as illustrated in the drawings and as hereinafter specified. Those things
which I claim as new and as my invention will be pointed out in the claims.
In a machine which I have designed I have, for convenience in timing the parts,
divided the circle representing a complete rotation of the main shaft into 32 equal
parts. While the main shaft in the machine which I have designed is making one
complete rotation, the operating parts each make a single complete operation.
To enable others to readily understand the timing of the movements of the
several parts, I will take the point which the crank in the main shaft will occupy
at the completion of one rotation and the commencement of the new rotation as the
starting point. This point is the upper dead center of the crank, and in the
drawings is indicated as 32°. Wherever I have hereinafter indicated the position
or time of movement of a part by degrees, the degrees refer to the 32° in which I
have divided the circle of rotation starting from the point above mentioned, and
indicate the position in relation to the crank in the main shaft.
In all of the views, except Figure 3, I have shown the parts in the position
which they will occupy when the crank in the main shaft has turned 2° from the
dead center, 32°, and in all of the views of cams I have marked the different
periods of movement by degrees. In Figure 3 the crank in the main shaft and
the operating parts are shown as having moved through 18°, or one half of a
rotation from the position shown in the other figures.
Similar letters refer to similar parts throughout the several views.
The base-plate A is made in suitable form to support the operative parts of the
machine, and is provided with various features hereinafter pointed out in connection
with the various operating parts. The form and other features may be varied to
suit the various requirements of the machine.
The upper-plate A¹ is supported from the base-plate A by columus a, as shown in
the several figures, and is firmly secured upon these columns a by strain-bars a'.
The size, number, position, and arrangement of the columns a may be varied to
suit the arrangement of the operative parts and the strength required, the arrange-
ment shown being the best known to me. The form and size of the upper-plate A'
must be such as to support the operative parts which are secured thereon, and to
withstand the pressure as hereinafter set forth, but these features may be varied
according to the requirements of the machine.
The main driving shaft B is supported in suitable bearings upon the upper-
plate A', as best shown in Figures 1 and 5. Upon this shaft B are secured two
driving wheels b, as best shown in Figures 1 and 5. Each driving wheel bis
driven by a pinion secured upon a shaft B', as best shown in Figure 5. Upon
the shaft B is secured a gear-wheel B which is driven by a pinion 62, as best
shown in Figures 1, 3, and 6. The pinion is secured upon a shaft B. This
shaft is provided with a fly-wheel 6 and is driven by an engine 13. The shafts B'
and B are mounted in suitable bearings supported from the base-plate A, and the
engine B' is also mounted upon the base plate A.
The gearing above described for driving the shaft B from the engine B is well
adapted and arranged for driving the shaft at the required speed with the required
power, but it is evident that the shaft B may be driven by any suitable power trans-
mitter separate from the remainder of the machine. I do not limit my invention
to the gearing shown for driving the shaft 13. When a belt is used, a band wheel
may be mounted on the shaft E in place of a crank for the engine B*.
The shaft B is provided with a crank c to which is connected the upper end of
a plunger C. The plunger C works in a cylinder C', as best shown in Figures 4
and 5. The cylinder C is provided with trunnions which are mounted in suitable
bearings secured upon the base plate A so that the cylinder C¹ can oscillate with
the plunger C.
The trunnions of the cylinder (" are hollow, as shown in Figure 5, and the
end of one of the trunnions is closed by a plug, while to the opposite trunnion is
attached a pipe C. The pipe C is provided with a head and the end of the
trunnion is countersunk to receive the head and a packing ring. The head is

page_text: secured in the countersink by a screw-threaded follower C* which firmly holds the
pipe C² in position while permitting the trunnion to turn.
The outer end of the pipe C enters a valve-chest D, as shown in Figure 5.
This valve-chest is connected with the large hydraulic cylinder D' by a pipe d, as
best shown in Figures 5 and 12. The cylinder D' is the large hydraulic cylinder
hereinafter referred to.
The valve-chest D is provided with a safety valve d, as shown in Figure 12,
which is held on to its seat by a weight as shown, but a spring valve may be
employed if desired. Above the valve d' is a chamber which receives the over-
flow from the pipe C³ when the valve is lifted. A pipe D' leads from the
chamber to a tank D³ (see Fig. 8). The valve chest D is provided with a check
valve and a pipe D' connects the port of the check-valve d with the tank D³.
As shown, the pipe D' is connected to the pipe D' by a T-coupling communicating
with the tank D; but it is evident that may be connected directly to the
tank D. The arrangement shown is the best arrangement for various reasons.
A ram E, as shown in Figure 4, is located in the cylinder D' which is firmly
supported upon the base plate A. In a machine which I have designed, the area
of the ram E is about six times the area of the plunger C, so that the ram E will
move about one-sixth the length of a stroke of the plunger C and at about one
sixth of its speed. The ram E moves about six inches and the plunger C moves
about thirty-six inches, the crank c being about eighteen inches in length. These
proportions may be varied to suit the requirements of different sized machines and
to suit different powers which it may be necessary to employ.
Each rotation of the shaft B forces the plunger C down into the cylinder C¹ and
withdraws it in position for another stroke. When the plunger C descends the
liquid in the cylinder C¹ will be forced through the piped into the cylinder D',
raising the ram E. The motion given to the plunger from the time the crank
leaves the dead center 32° until it reaches about 20 is very slight, while from 20
down to about 14° it is quite rapid, so that the ram E will be lifted first slowly and
then with comparative rapidity until near the end of its movement. From about 14°
to about. 16° (which is the lower dead center) the downward movement of the
plunger is slight and the power of the crank is very great. It is at this point that
the heavy pressure is needed on the ram E, and the advantage which the crank
gains at this point, together with the momentum of the driving gearing, will
carry the crank by the dead center with great force. The advantage of this
will appear hereinafter where the operation of the ram is specifically set forth.
The safety valve d' is weighted to withstand a desired pressure. When the
ram E meets with an unusual amount of resistance, the cylinders C and D¹ will be
relieved of the excessive pressure caused by such resistance by the liquid passing
into the chamber through the pipe D' to the tank D³. It will be understood
that the pipe D2 and chamber are entirely filled with the liquid, while the
tank D³ is partially filled. The escape of the liquid through the safety valve d'
will relieve the cylinders of the excessive pressure above the amount to which the
valve d is weighted, so that the crank c will pass the lower dead center.
When the plunger C begins to rise it rises slowly at first, then comparatively
rapid. The rising of the plunger C will draw the liquid from the cylinder D' into
the cylinder C¹, the weight of the ram E causing the liquid to flow rapidly. When
the ram E has reached its lower limit, enough liquid will be drawn through the
check valve d³ from the pipe D' and tank D to fill the cylinder C. The check
valve d³ will prevent the passage of any liquid through the port when the
plunger C is descending.
A set-bolt D is screwed into the lower end of the ram E so that it will engage
with the bottom of the cylinder D' and limit the descent of the ram E. This
bolt D' may be set so that it will stop the descent of the ram at the point necessary
to cause it to be lifted to the proper point in operation, as hereinafter set forth.
By properly adjusting the weight on the valve d', the excessive pressure may be

page_text: relieved while the crank is passing through a few degrees near its lower dead center,
thereby holding the ram E up under the predetermined pressure while the crank is
passing through these degrees, as hereinafter explained.
The mold blocks Fare mounted in a turn-table F', as best shown in Figures 4
and 6. As shown, I have provided the turn-table F with six mold blocks, and I
have, therefore, designed the parts which operate with the turn-table to operate
correspondingly; but it is evident that the number of mold blocks F may be varied
and the parts operating therewith varied accordingly.
oil
The turn-table F is supported from a cylindrical column F, as best shown in
Figure 4 and hereinafter set forth. This column F is provided with an annular
groove at its top adapted to receive an annular guiding ring on the under side
of an annular supporting plate F. A spur-gearf is secured upon the plate F³, as
shown in Figures 4 and 6, by which the supporting plate and turn-table are turned,
as hereinafter described.
As shown in Figure 4, the turn-table F' is secured to a flange f¹ depending from
the plate F. A cap-plate F made in sections is secured upon the flange above
the turn-table F¹ and holds the mold blocks F in the turn table. Each mold
block F, as shown, contains five molds, as it is designed for pressing five bricks or
blocks at one time; but the number of molds in each block may be varied as
desired.
Each mold-block is provided with a shoulder which rests upon a ledge in the
turn table F¹, and. each mold block can be lifted vertically in the turn table for
purposes hereinafter set forth.
As best shown in Figure 17, each mold is lined by hard metal plates which
are double mitered at their edges so that they can be reversed when one side is
worn. The corners of the openings in the blocks F which receive the plates / are
left full to the extent of the double miter. This avoids sharp angles in the block F
and strengthens the block F at its weakest point. The metal plates are held in
place, as shown in Figures 4 and 6, by plates f, one above and one below, secured
to the mold block F. The use of the securing plates enables the plates/³ to be
secured in place without the use of screws or rivets, which would injure the wearing
capacity of the plates f³.
Below the turn table F¹ is a series of plunger blocks E. There are as many
plunger blocks E' as there are mold blocks F. Each plunger block E' is provided
with plungers e arranged to enter the molds in the mold block F. The under
side of each plunger block E' is adapted to be engaged by the ram E when brought
into proper position, as shown in Figures 4 and 7. The inner end of each block is
secured to a vertically sliding guide block E, as shown in Figures 4 and 7. Each
guide block E has its vertical edges formed as guides, as shown in Figure 17,
adapted to enter grooves in a shell F depending from the flange f¹, as shown in
Figure 4. This shell F rotates with the turn table F', carrying with it the
plunger blocks E', and the guide blocks E of the plunger blocks E' can slide
vertically in this shell F. Each guide block F is provided with an anti-friction
roller or wheel el which runs upon a track e secured to or formed with the
column F. This track e has an upward incline on the front side of the machine
in advance of the mechanical feed mechanism hereinafter set forth and indicated
in Figure 2, and on the rear side of the machine it has a downward incline.
By this arrangement each plunger block E is raised to a little above the level
of the upper end of the ram E, so that the plungers e will enter the molds in the
corresponding mold block Fa short distance. When the mold block arrives at the
point where the molds are filled, it will be held in that position until after it has
passed the ram E, when the plunger block will descend, as shown, for purposes
hereinafter set forth.
The upper plungers g are secured to the under side of a plunger block G. The
plunger block G, as shown in Figure 16, is provided with guides g' which enter
grooves in a resistance block G³, as shown in Figures 4 and 16. The plunger

page_text: BLOCK IS provide with vertical grooves adapted to receive guides g" which guide
the plunger block G in its vertical movements. The guides 9 are secured to the
under side of the upper plate A¹.
The upper and lower surfaces of the block G¹ are inclined, as shown in Figure 4.
The upper inclined surface of the block G' is in contact with the incline on the
lower side of the upper plate A'. The lower inclined surface of the block_G'
engages with an incline upon the plunger block G, as shown in Figure 4. The
block G¹ is supported by guides g³, as shown in Figure 16, so that it can slide
horizontally. When the block G is in the position shown in Figure 4, the plunger
block G will be raised clear from the mold block F. When the resistance block G¹
is drawn in, the plunger block G will be lowered so that the plungers g will enter
the upper ends of the molds in the mold block F. When the lower plungers e are
raised by the ram E, the upper plungers 9 will remain stationary and resist the
upward pressure, so that the material in the mold will be pressed between the
plungers e and g. When the ram E rises, the plunger block G is firmly held down
with the plungers g in the molds by the resistance block G', which is capable of
withstanding the immense upward pressure exerted by the ram E against the upper
plunger block G.
g
In order to prevent the upper plate A¹ from being lifted or sprung by the
immense upward pressure, I provide three columns a arranged in triangular form
about the cylinder D', as shown in Figure 7, through which pass large strain bars A².
The strain bars A* are arranged at about equal distances from the center of the
cylinder D', so that they divide about equally the strain upon the plate A'. One
of these columns a² and strain bars A pass through the column F.
The resistance block G is moved in and out by a link g which is pivotally
connected at its other end with an elbow lever G3 which is secured upon a rock-
shaft y, as shown in Figures 1, 3 and 4. The other end of the lever G³ is provided
with an anti-friction roller which engages with a face cam G*. The cam G³ is
mounted upon a shaft G. Upon this shaft G is also secured a spur-gear wheel G
which meshes with a spur gear wheel G secured upon the shaft B, as shown in
Figures 1 and 4. The wheels G' and G' are of equal diameter so that they rotate
with equal speed.
с
When the crank c is at 2° the cam G³ will be turned so that the point marked 1°
will engage with the roller 9, as shown in Figure 4. The block G is then shoved
out as shown.
When the cam G³ rotates from 2° to 5° the upper arm of the lever G³ will be
swung downwardly and its lower arm will be swung barkwardly, drawing the
block G¹ forward and lowering the plunger block G so that the plungers g will
enter the molds in the mold block F. This will bring the resistance block G¹ and
the plungers g into position at the time when the ram E begins to lift the plunger
block E and lower plungers e.
While the crank c is passing from 5° to 19° the pressure upon the resistance
block G¹ from the ram E will be immense and the block will remain firmly
in position. The portion of the cam G³ which passes the roller during this
time is circular, as shown. After the crank chas passed 19° the pressure is
off the plunger and block G¹ and the plungers are then lifted by the
block G being pushed out by means of the cam G³ engaging with the roller
from 19° to 23°. From 23° up to 1° the block G¹ remains stationary in its outer
position, as shown in Figure 4, the cam G³ from 23° to 2° being circular.
It will thus be seen that the resistance block G' is drawn in at the proper time
to lower the plungers y to meet and resist the plungers e, which begin to be lifted
by the ram E.
The resistance block G¹ is inclined, as shown and hereinbefore described, to
raise and lower the plunger block G, which is the preferable form; but it is
evident that the plunger block G may be raised and lowered by other means.
The chief office of the resistance block G' is to furnish a perfectly solid resistance
to the upward pressure of the ram. In the machine which I have designed the

page_text: plungers y are not given sufficient downward movement to cause them to act as
compressers of the material in the molds, but they simply form resistant plungers
against which the plungers e press the material to form the bricks or blocks.
The mold blocks Fare made to slide vertically in the turn table F¹ so that the
molds can rise with the lower plungers, if necessary, and so that the material in
the molds will be pressed uniformly forming perfect bricks or blocks. The block E!
is raised vertically by the ram E, its roller e¹ being raised from the track e³ and
its guide block E sliding vertically in the shell F.
When the plungers e and y have been withdrawn from the molds, the turn
table is turned sufficiently to bring another mold block with filled molds into
position over the ram E.
The spur-wheelf which is connected with the turn table F', is rotated by a
spur-wheel h, as best shown in Figure 6. This spur wheel in a machine which I
have designed, has one half as many cogs as the spur wheel, so that when it
rotates twice it will cause the spur wheelf to rotate once.
This wheel is secured upon a shaft which is secured in suitable bearings in
the plate A' and in a support H, as best shown in Figure 3. One end of the
shait G is also supported in this support H, as shown in Figure 1, its other end
being mounted in bearings upon a support H as shown in Figure 2. Upon the
upper end of the shaft is mounted a wheel or disk H which is provided with
six anti-friction rollers H', as best shown in Figure 1. This wheel or disk H is
secured to the shaft h' by a clutch hereinafter described.
The rollers H' are arranged to enter grooves in a cam wheel I' which is secured
upon the shaft G and is provided with a groove i adapted to receive one of the
rollers H' and extending outwardly a short distance from a circular recess ¹ at the
center, as best shown in Figure 19; it then extends around the wheel I' nearly
from 1° to 23° in a circle. It then extends outwardly to the periphery of the
wheel. A second groove extends outwardly from the center to the periphery
of the wheel.
When the crank c has passed to 23°, the resistance block G' has been pushed
out and withdrawn the plungers g from the molds, as before stated, and the ram E
has descended so that the plunger block E' can turn with the molds. The turn
table F is now free to turn, and must be turned one sixth of a rotation to bring a
second mold block into position.
When the crank is at 23° a roller H' will be at 23° in the groove i in the cam-
wheel I. The continued rotation of the wheel I will cause the roller H¹ to be
moved in the outwardly extending portion of the groove, thereby rotating the
wheel H, and before one roller H₁ has passed out of the groove i, a second
roller H' will enter the groove at the center and pass outwardly to the
periphery of the wheel I', and a second roller H' will enter the groove i passing
outwardly until it strikes the circular portion beginning at 1°. The wheel H has
thus been rotated through an interval of two rollers H', or one third of a rotation.
This has been done while the crank c is passing from 23° to 1° Fig. 19. The
rotation of the wheel H has caused the spur to rotate likewise, and has rotated
the spur-wheel fand turn table F¹ one sixth of a rotation, thereby bringing a
second mold block into position for a second operation.
When the roller H₁ enters a circular portion of the groove i at 1° the wheel H
and turn table F¹ will be prevented from rotating or oscillating either forwardly
or backwardly. The roller H' will remain in the circular groove i to 23° so that
the turn table F will be held perfectly stationary while the crank c is passing
from 1° to 23°, during which time the plungers e and genter the molds in the
mold block F on the turn table F' and press the material forming the bricks or
blocks.
The bricks or blocks formed in the molds in the mold blocks F are carried
around in the molds, after leaving the plungers e and g, one half of the rotation of
the turn table F in the machine which I have designed. They are there pushed
out upon a belt or other carrier Kas hereinafter described,

page_text: The bricks or blocks are pushed out of the molds by plungers ; which are
secured to a push-out block J. The plungers j are made in such form and arranged
so that they will enter the molds and push out the blocks readily.
The push-out J is guided in a frame J¹ so that it will move in a vertical line.
To the push-out block J is pivotally connected a connecting rod which at its
other end is pivotally connected to two arms. The arms are secured upon a
rock shaft J, as shown in Figures 1 and 4, and upon the outer end of the rock
shaft J is secured an arm . To the armis is pivotally connected a pitman J
which at its other end is pivotally connected with a crank J* secured upon the
shaft G4.
C
Each rotation of the shaft G will rock the rock shaft J and arms through
the crank J and pitman J³. The crank J is set at about 16° in relation to the
crank in the shaft B. When the crank is passing from about 16° to about 2°,
the push-out plungers; are moving upwardly and back above the surfaces of the
mold blocks F, as the crank J is set upon the shaft G so that it is pulling the
arm forwardly and raising the arms. While the crank c is passing from
about 1° to about 16°, which is the period that the turn table is at rest, the push-
out plungers j pass lown into the molds in the mold block F, push out the bricks
or blocks on to the carrier K and return above the surface of the mold blocks F.
To the columns a and u² arranged around the turn table F¹, as shown in
Figure 6, are secured brackets in which are mounted anti-friction rollers H³, as
indicated in dotted lines in Figure 6. These anti-friction rollers H² are arranged
to engage with the under side of the turn table F¹ and prevent its being twisted by
the action of the push-out plungers, or the plungers e and g..
The carrier K is arranged beneath the push-outs j so that it will carry away the
bricks or blocks pushed out from the molds.
The plunger blocks E' descend by means of the incline in the track e³, so that
they pass beneath the carrier K. The inner end of the belt which I employ as a
carrier runs over a pulley K', as best shown in Figure 7. This pulley K' is
supported upon brackets K² extending out from the columns a.
It is most convenient to deliver the pressed brick or blocks to the carrier Kat
the point which I have shown and described; but it is evident that the push out j
and operating devices and the carrier K, may be arranged at other convenient
points where they can operate while the turn table is not moving. The arrangement
shown I consider preferable for many reasons.
The wheel H is loosely mounted upon the shaft, as best shown in Figure 18,
and the upper face of its hub is provided with a beveled clutch recess ², as best
shown in Figures 21 and 22. A clutch section ³ is secured upon the shaft h¹
above the wheel H by a spline or feather so that it can be moved longitudinally
thereon. It is provided with a beveled portion adapted to engage with the
recessed portion of the hub. This section is held in contact with the hub of
the wheel H by a spring * which at its upper end abuts against a set-nut h³.
In case any of the .plungers e, g, or j fail for any reason to be freed from the
turn table F, or in case from any other cause the turn table could not be turned,
the unusual power necessary to turn the table will cause the clutch section on the
hub of the wheel H to lift the clutch section and thereby permit the wheel H to
rotate without rotating the shaft h. The tension of the spring * may be adjusted
to allow the clutch section to be lifted at the desired time to prevent breakage.
If the clutch section is lifted, as above described, the turn table will remain
stationary until the wheel H has made a complete rotation, so that the plungers e, g,
and will work in the molds and not strike the turn table F".
The shaft h, as shown in Figure 18, is made hollow, and a rod extends
longitudinally through it. The rod at its upper end is provided with a pin h
which projects through vertical slots in the shaft and enters an annular recess h³
in the clutch section. The lower end of the rod engages with an arm hon a
rod 10, which is supported in brackets ", as best shown in Figures 6 and 18.

page_text: The outer end of the rod is provided with a handle h™ by which it may be
rocked.
The operator can raise the rod h by rocking the rod 10 by the handle h¹³,
thereby raising the clutch section out of engagement with the wheel H, so that
at any time the operator can throw the devices for driving the turn table, out
of gear.
The foregoing description gives in detail the operation of the respective parts
for pressing the material in the molds, for turning the turn table containing the
molds, and removing the pressed bricks or blocks from the molds, the molds
being filled by mechanism hereinafter described.
In order that the general operation of the machine may be understood. I will
now give a general description of a single operation of the parts herein before
described; starting for convenience with the crank c at 2°, the parts will be in the
position shown in all the figures except Figure 3. At this time the plunger C is
beginning to descend, and the cam G³ is just beginning to rock the elbow lever G*
to draw the resistance block G' and cause the plunger block G to descend; the
roller H' has just arrived at the circular portion of the groove i in the cam I¹, so
that the turn table is at rest, and the push out plungers; have just entered the
mold.
While the crank c is passing from 2° to 5° the plunger C is descending slowly
causing the ram E to rise slowly and engage with the plunger blocks E', and at 5°
the resistance block G¹ has been drawn to its seat by the cam G and intermediate
devices, lowering the plungers into the molds in the mold block F. From 5°
onward to 16° all the parts of the machine herein before mentioned are at rest
excepting the plunger C, ram E, and the push out devices. The descent of the
plunger C from 5° onward is comparatively rapid, causing the ram E to rise,
lifting the plunger block E' and plungers e and compressing the material in the
molds. When the crank arrives at about 14°, the downward descent of the
plunger C is comparatively very slow, and at this time the greatest pressure is
exerted upward upon the ram E and plungers e which are then finally compressing
the material.
By reason of the fact that the crank c is approaching its lower dead center, 16º,
it is acting with the greatest advantage to force the plunger C downward. At
this time the greatest compressing power is necessary, as at all other times the
resistance is small and at this time the plungers are finally compressing the
material.
The advantage gained by the crank c while approaching its dead center enables
the driving power to carry the crank by this nip with the greatest advantage,
and utilizes the momentum at the very time when the greatest force is required.
The resistance block G¹ being a solid block and the plunger block G pressing
against it, and it in turn pressing against the upper plate, a solid and unyielding
support is given to the upper plungers g which remain at rest at this time.
If the resistance offered by the material being pressed passes beyond a certain
predetermined point, as for instance, four hundred tons, the safety valve will be
lifted, allowing a sufficient amount of the liquid to overflow to prevent breakage,
as hereinbefore set forth.
It will thus be observed that the plunger C descends very slowly and is com-
paratively stationary while the crank c is passing the dead center, thereby holding
the material being pressed under the greatest pressure for a considerable time. As
soon as the plunger C begins to rise, the pressure is relieved from the plungers e
and and the ram E with the plunger block E¹ begins to descend, gradually
relieving the machine of its immense strain. When the crank c begins to lift the
plunger more rapidly, the ram E descends quite rapidly, forcing the liquid in the
cylinder D' back into the cylinder C¹.
When the crank c rotates to 19° the pressure is entirely off from the resistance
block G', and the block G¹ is moved outwardly by the cam G' and intermediate

page_text: devices, raising the plungers g, and when the crank c arrives at 23°, the block G¹
is fully out and the plunger block E' free to turn with the table. By this time the
plunger block E has been freed from the ram E by the descent of said ram.
At 23°, therefore, the turn table is free to move as regards these parts. It will be
remembered that the lower plungers rotate with the molds in the turn table. While
the operation above described has been taking place, the push out plungers ; have
pushed out the bricks or blocks from the molds and have returned above the edge
of the molds; the turn table is therefore ready.to be moved and at 23° is turned
rapidly one sixth of a rotation, in the machine which I have designed, by means of
the cam wheel I¹ and intermediate devices hereinbefore described. From 23° to 1°
the table is rotating and 1° it stops ready for a second operation.
While the crank c was passing from 16° to 32° the liquid was being withdrawn
from the cylinder D' into the cylinder C, and any overflow was being taken up as
herein before described, so that at 32° the crank is ready for a second operation,
and at 2° (the starting point) has begun its second operation.
As hereinbefore stated, in case either of the plungers e, g, or j should fail to be
clear from the mold blocks F, the turn table F1 cannot be turned and the clutch
section will be lifted by the unusual strain, thereby throwing the driving
mechanism for the turn table out of gear and preventing accident. If for any
similar reason it is necessary to throw the turn table out of action, the operator can
do so by means of the handle h¹.
I will now describe the mechanisms by which the material is supplied to the
molds.
The base plate A is extended on one side, as shown in Figures 6 and 7, to form
a support for the mechanisms for feeding the material to the molds. As the
plungers e are caused to enter the molds at one sixth of a rotation from the ram E
and at that point close the bottoms of the molds, I have arranged the feed
mechanism to operate at that point. It is evident, however, that the feed mechanism
can be arranged at any other desired point at which the molds can be closed by the
lower plungers e.
When more or less than six mold blocks are used in the turn
table F, the position of the feed mechanism may be shifted as necessary. The
arrangement shown is preferable for various reasons, and the base plate A is
extended at the point shown in order to support the operating parts.
A mixing tank L is supported upon the column L' extending up from the base A,
as best shown in Figure 8. The column L' is supported in a step box L³ secured
upon the base plate A, and at its upper end is provided with a flange l to which the
mixing tank L is bolted. This column L' is hollow, as shown in Figure 8, for
purposes hereinafter set forth.
The mixing tank L is composed of plate metal and provided with steam
passages, as best shown in Figure 8. The two plates forming the tank L are
bolted to a ring which is secured upon the flange 1. Upon the ring ³ is also
bolted a vertical box L³.
The mixers m are secured upon arms M which are mounted upon a shaft M'.
The shaft M is located within the hollow column L' and supported at its upper
end in the vertical box L. At its lower end it rests in a bearing block m¹. As
shown, this shaft M' is provided with a beveled gear wheel m² below the base
plate A, by which wheel the shaft M', arms M, and mixers m are rotated.
The beveled gear wheel m³ is driven by a beveled gear wheel m³ upon a shaft M²,
as best shown in Figures 8 and 9.
One end of the shaft M is supported in the block m¹, and the block m² is
supported by a bracket M², as best shown in Figures.
and 9.
Upon the inner end of the shaft M' is secured a band wheel m', as best
shown in Figure 9. This band wheel m* and the parts connected therewith are
not shown in Figures 2 and 5, as they would conceal some of the important parts
there shown.
The gearing for driving the band wheel m² is clearly shown in Figure 15. A
band M passes around the wheel m' secured upon the shaft B', and also around the
R

page_text: band wheel m². At the point of passing through the base A, two guide pulleys m*
and m² are located, as shown in Figure 15.
The gearing for driving the shaft M' from the shaft B' may be regulated to
drive the shaft M' at any desired speed. The form of gearing is unimportant.
Upon the shaft B, as shown in Figure 15, is secured a sprocket-wheel n which
drives a drive-chain N. This drive chain N passes around a sprocket wheel n
upon a shaft N' which is supported in suitable bearings upon the base plate A, as
best shown in Figures 7 and 15. Upon the outer end of the shaft N¹ is secured a
beveled gear wheel, as best shown in Figures 7 and 8.
A shaft O is mounted in suitable bearings upon columns O' upon the extension
of the base plate A, as shown in Figure 7, and is provided with a beveled
gear wheel O' which meshes with the beveled gear wheel n³. The gearing
between the shaft O and the shaft B is such that the shaft O rotates at the same
'speed as the shaft B.
The feed box P is provided with two guides one on each side. A track P' is
provided with anti-friction rollers p' provided with grooves adapted to receive the
guides p of the feed box P, as shown in Figure 8. The feed box P can be moved
on the anti-friction rollers from the position shown in Figure 10 where it is filled,
to a position immediately above the molds in one of the mold boxes F in the turn
table F¹.
A lever P¹ is connected with the old box P by a link , as shown in Figures 9
and 10. At its opposite end it is mounted upon a pivot psecured in one of the
columns O. This lever P' is provided with an anti-friction roller p¹ adapted to
enter a cam-groovey in the cam wheel Q. The cam wheel Q is secured upon the
shaft O, as best shown in Figure 10. While the turn table is at rest, that is,
while the crank c is passing from 1° to 23°, the feed box must pass to the molds in
the mold block F, fill the molds, and return. When the crank c arrives at 1°, the
portion of the cam groove q indicated at 1° (see Figure 10) will be at the roller pl.
From this point to the point marked 5° the cam groove q extends outwardly
towards the periphery, so that while the cam is passing from 1° to 5° the anti-
friction roller p¹ and lever P₁ will be moved inwardly, thereby carrying the
feed box rapidly inward from the position shown in Figure 10 to a point above
a mold block F.
From 5° to 14°, as indicated in Figure 10, the cam groove 9 is circular, so that
while the crank c is passing from 5° to 14° the feed box will remain stationary
over the mold block F. The feed box is returned from 14° to 19° as herein after
set forth.
The feed box P is provided with a movable bottom R. This movable bottom R
is provided with guides, as shown in Figure 8, which enter grooves in the anti-
friction rollers p². The bottom R is provided with a hook which extends outward,
as shown in Figures 9 and 10.
A cam wheel R' is secured upon the shaft O, as shown in Figure 11. This cam
wheel R is provided with a cam groove. A lever S is pivoted upon the
shaft at its lower end, and its upper end is connected with a hook S¹ by a
link S⁹.
The hook S¹ slides upon a guide S³, as best shown in Figure 11. The
hook S¹ is arranged in position to engage with the hook upon the feed box P
when the feed box is moved into its inner position, and to draw the bottom R
outward so that the contents of the feed box P can fall into the molds in the mold
blocks F.
The lever S is provided with an anti-friction roller & which runs in the cam
groove. The parts will be in the position shown in Figure 11, at 2°, at which
time the box P is moving towards the mold block F. The feed box P will arrive
at its destination at 5°. At this time the cam groove will be moved so that the
point indicated at 5° will pass the roller s. From 5° to 9° the cam groove
extends towards the center of the wheel R' so that the rollers and lever Š will be
moved outwardly to the position indicated by dotted lines in Figure 11. This will

page_text: draw the hook S' outwardly and will withdraw the bottom R from the feed box P.
From 9° to 14° the cam groove ¹ extends outwardly from the center of the wheel R',
so that the lever S will return to the position shown in Figure 11, and the hook Sí
be entirely disengaged from the bottom R. From 14° to 5° the cam is circular,
so that the lever S and rollers will be at rest.
From 14° to 19° the cam groove 9 extends inwardly towards the center of the
cam wheel Q, as shown in Figure 10, so that the roller p² and lever P¹ will be
moved outwardly rapidly, thereby returning the feed box P to the station at which
it is filled. When the feed box P returns it overtakes the bottom R which is
stopped by the engagement of the hook r with a bracket upon a vertical rock
shaft U hereinafter described, the arrangement being such that the bottom R and
feed box P stop immediately beneath a measuring device hereinafter set forth.
The bracket may be arranged upon any other convenient part of the mechanism
to stop the bottom R at the proper point. From 19° to 1° the cam groove q is
circular, so that the feed box P is held stationary in the position shown in
Figure 10. The lever P¹ is provided with a slot p³ to permit it to straddle the
shaft O.
The tank L is provided with an opening t³, as shown in Figures 1 and 10.
Beneath this opening is located a measuring box T, which is preferably made
similar in form in cross section to the feed box P. This measuring box T
consists of two sections. The upper section t is supported from the mixing tank L
by a bracket t. The lower section, t, is of larger diameter and is adapted to slide
over the upper section t. The lower section t¹ is supported by a bracket t*, which
is attached to a collar T¹ which surrounds a rock shaft U which surrounds the
vertical column L, as best shown in Figure 8. The collar T' is supported by a
shoulder U³.
The vertical rock shaft U at its lower end rests upon a block u¹, which block is
provided with an annular oil groove in which the rock shaft U may turn, as shown
in Figure 8. The block u¹ is located in a countersink in the step block Ĺ³, as best
shown in Figure 8. This block u' is supported by a collar ², which is provided
with an arm that extends outwardly and is provided with a head through which
passes a screw bolt u, which is provided with a handwheel u°. The screw u* at its
lower end is supported in a stand U*. By means of the hand wheel u³, screw u*,
arm, and collar u³, the block ¹ may be raised or lowered, thereby raising the
rock-shaft U. By raising the shaft U, the collar T¹ and section t¹ of the measuring
box T may be raised or lowered, thereby decreasing or increasing the amount of
material fed to the feed box P.
The plate u, which forms the bottom of the measuring box T, is provided with a
collar T which surrounds the rock-shaft U and is secured upon the shoulder u³.
The collar T¹ rests upon this collar T³.
The plate u', which forms the lid to the measuring box T, is provided with a
collar T3 which is secured upon the upper end of a sleeve T, as best shown in
Figure 8. The sleeve T rests upon a collar which is secured by screws to the
column L', as shown in Figure 8.
The sleeve T is provided with a spline to which enters a groove in the interior
of the rock shaft U and causes the sleeve T to rock with the rock shaft U
while enabling the rock shaft U to move longitudinally without moving the
sleeve T*.
The plates u and u¹ are so set upon the shaft U and the sleeve T', which is in
effect a part of the shaft U, that when the plate u closes the bottom of the
measuring box T, the plate u¹ will be moved from the top, allowing the measuring
box T to be filled with material from the mixing tank L, as shown in Figure 14.
When the bottom plate u is moved from beneath the measuring box T, the top plate
or lid will be moved over the top of the measuring box T, thereby preventing
more material from entering the box T, and also measuring the amount of material
to be used for a single operation of the machine.
The amount of material which the measuring box T can contain may be varied.

page_text: by raising or lowering the lower section t' by raising the rock shaft U, as herein-
before described, the bottom plate u rising with the rock shaft U, and
lower section ', the upper section t, lid u', and sleeve T' remaining in the same
horizontal plane.
In order that the rock shaft U may be rocked to shift the plate and lid u³, as
above described, this rock shaft U at its lower portion is provided with gear-
teeth r, as shown in Figures 8, 9, and 10, and indicated by dotted lines in Figure 14,
which are engaged by teeth upon a rack bar V. The teeth v' upon the rack
bar V are quite wide, so that they will engage with the teeth von the shaft U in
its different positions, as adjusted.
The rack bar V is supported upon and guided by anti-friction rollers which
are mounted upon standards V', as best shown in Figure 13.
The rack bar V is provided with an anti-friction roller to which runs in a cam
groove w¹ in the face of a wheel W, as best shown in Figure 13.
When the crank c is at 1° the roller w will be in the circular portion of the
groove w. The groove w¹ is circular from 1° to 19³, as indicated in Figure 13.
From 19° to 23° it extends inwardly towards the center of the wheel W. From 23°
to 30° it is circular, and from 30° to 1° it extends outwardly towards the periphery
of the wheel W.
This will cause the rack V to occupy the position shown in Figure 1 from 1°
to 19° which will cause the plates u and u¹ to occupy the position shown in
Figure 14, at which time the measuring box T will be filled. During this time the
feed box P will be going to the mold, filling the mold, and returning. From 19°
to 23° the rack will be shifted to the position indicated by dotted lines in
Figure 13, opening the bottom of the measuring box T and closing the lid u'.
From 23° to 30° the bottom plate will be open, so that the material in the
measuring box T will fall into the feed box P. From 30° to 1° the plates and u
will be shifted, closing the bottom and opening the top of the measuring box T, the
rack V being returned to the position shown in Figure 13. The rack bar V is
provided with a slot V, so that it can straddle the shaft O.
From the foregoing description, it will be understood that during the period that
the turn table 1 is at rest, that is, from 1 to 23°, the feed box P moves in over
the mold block, its bottom is withdrawn, allowing the material to fall into the mold
block, and the feed box to then return to its station beneath the measuring box.
When the mok box arrives at the position shown in the several figures, the bottom
plate closes the bottom of the measuring box and the crank is at 19°. From 19°
to 23° the plate u is shifted, opening the bottom, and the upper plate u' is shifted,
cutting off the top of the measuring box T. From 23° to 30° the feed box is filled
with material from the measuring box T. From 30° to 31°, the plates and u¹ are
shifted back, when the feed box is again ready to move forward and fill the molds
in a second block. From 23° to 30°, that is, during the time while the turn table F¹
is turning, the feed box is being filled and at 1° is ready to move in to the turn
table which comes to rest at 1°.
The entire feeding apparatus moves automatically in proper relation to the
movements of the turn table and pressing apparatus, so that the pressing alone
is done by the ram E and at that point, the bricks or blocks being pushed out
by separate apparatus. This construction and combinations of mechanisms
allows the pressing to be done more slowly and with better effect than would be
the case were the molds fed at the point of pressing and the bricks or blocks
removed at the same point. The mechanisms hereinbefore described are all
designed to operate in relation to each other; but many of the mechanisms
will be operated in connection with other mechanisms now in use.
Having now described the mechanisms which form my improved hydraulic
machine, and the construction set forth in the drawings and the mode of opera-
tion of the several parts, and of the mechanisms as a whole, I desire it to be
understood that the different mechanisms which I have employed are the
preferred forms of various forms of mechanisms which I have contemplated and

page_text: which may be effectually employed for carrying out the main features of my
invention, one of which is the hydraulic ram which is operated by a plunger
driven by a crank so as to cause the ram to make a single operation with the
greatest amount of power upon each complete operation of the remaining parts of
the machine, and automatic mechanisms which will cause the co-acting devices of the
machine to act in unison with the ram; and another of which main features is the
turn table and the automatic devices co-operating therewith to utilize the hydraulic
ram E and plunger C. It is evident that various forms of gearing may be employed
to operate some of the automatic parts, such as a cam for operating the push out
plungers j.
The construction which I have shown and have fully described is the
preferred one in all details, and is one which I have designed for actual
employment.
The system of timing which I have hereinbefore explained and which I have
made use of in explaining the operation of the several operating parts, is one
adopted simply for convenience in the construction of my machine and the descrip-
tion of the operation. It is evident, therefore, that the scale employed is not an
essential part of my invention, but is merely an aid in describing the timing of the
parts which must act automatically at certain times in relation to other operating
parts. I do not, therefore, limit my invention to the precise gearing and mechanism
employed in every instance, but what I consider important and claim as my inven-
tion will be set forth in the claims.
