Improvements in Machines for the Manufacture of Bricks.
We, THEOPHILE EDOUARD AYOTTE, of 41, Pontiac Street, Civil Employee, and
ARTHUR ALBERT CHARBONEAU, of 74, Clark Street, Cigarmaker, both in the City
and District of Montreal, in the Province of Quebec, Dominion of Canada, 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:
This invention relates to machines for the manufacture of bricks. artificial
stone and ornamental bricks, and the object is to provide a machine of this
character that may be operated with dry or semi-dry clay, and with which a com-
paratively large number of bricks may be formed with the help of one or two
operators.
We will describe a brick machine embodying our invention, and then point out
the novel feature in the appended claims.

Referring to the drawings, 1 designates a frame, which must be strongly
constructed so that it will resist the vibration caused by the working of the
Price 8dl

page_text: machine. Mounted to move vertically in suitable guideways at the end of the
frame 1, are the upper plungers 2 and 3 and the co-acting lower plungers 4
and 5. The upper plungers 2 and 3 are operated respectively by levers 6 and 7,
which are fulcrumed at one end of the machine frame, and have links 8 and 9
extended to the plungers. The levers 6 and 7 are horizontally disposed, and
from the outer end of the levers 6, arms 10 extend downward and have roller
engagement at their lower ends in cam grooves formed in cam disks 11 mounted
on the driving shaft 12. The levers 7 have arms 13 similar to the arms 10. and
engaging with cams at the opposite end of the machine similarly to the cam
disks 11. The cams for the arms 10 and 13 are operated by a longitudinally
disposed shaft 14. having bevel gears 15 engaging with gears 24 on the shafts 12.
One shaft 12 has a gear wheel 17 secured to it, and this bevel gear 17 engages
with a pinion 18 on the shaft of the gear wheel 19 meshing with a pinion 20
secured to the shaft of a driving pulley 21, from which power may be transmitted
by any suitable motor.
The lower plungers 4 and 5 have link connections with levers 22 and 23. The
outer ends of the levers 22 engage in grooves in cam disks 24" mounted on the
shaft 12, and the levers 23 engage with similar cams on the shaft operated by
the shaft 14. The several plungers have head portions each of a surface area
equal to that of a brick or similar article to be manufactured, and there may
be any desired number of these heads on the plungers, equalling of course the
number of openings in the mould.
The mould, as shown in Figure 5, comprises a frame 25, having two sets of
mold cavities 26, one set designed to be operated in connection with the plungers 2
and 4, and the other set in connection with the plungers 3 and 5. The mould-
board or frame 25 is movable longitudinally of the frame 1. As here shown,
it is provided at its opposite sides with tongues engaging in slideways in the sides
of the frame. Reciprocating motion is imparted to the mould-board or frame 25
by means of levers 27 fulcrumed on the frame 1, and having link connections 28
with pins extended from the tongue portions of the mould-board through longi-
tudinal slots in the frame. The lower ends of the levers 27 are connected to
rods 29, having pins 30 extended into cam grooves 31 of cam disks 32 mounted
on a shaft driven by means of a gear wheel 33. mounted on said shaft and
engaging with a pinion 34 on the shaft operating the arms 13.
It may be hete
stated, that the arms 10 and 13 are held substantially in vertical alignment by
means of pins 35 extended into slots formed vertically in the side frames 1.
Mounted in the frame 1 between the sets of plungers is a clay mixing casing 36,
which may be divided by means of a central partition into two chambers, and
in each chamber a shaft 37 is mounted to rotate. On the shatt 37 are outwardly
extending fingers 38, and at the lower ends of the shafts are spirally disposed
feeding blades 39. The upper ends of the shafts 37 are provided with bevel
gears 40 engaging with bevel gears 41 on the shaft 2 mounted in beatings on
the top of the casing 36, and the outer end of this shatt 42 is provided with a
sprocket wheel 43, from which a sprocket chain 44 extends to a connection with
a sprocket wheel 45 on the shaft of the driving pulley 21.
In the lower portion of the casing 36 is a rating 46. having a number of
openings equal to the number of openings in each section of the mould-board,
and designed to register at a certain time with the openings in the mould-board.
This grating 46 consists of upper and lower sectious, and between the upper and
lower sections a clay-cutting device is movable. This clay cutting device consists
of a frame 47 designed to be reciprocated across the grating and having a number
of cutting wires 48. Reciprocating motion is imparted to the cutting device
by means of a cam 49 mounted on the shaft 14, and in the cam groove of which
a roller on an angle lever 50 engages. The vertically disposed member of the
angle lever 50 is fulerumed to a bracket 1 extended outward from the frame,
and the upper end of this vertically disposed portion of the lever is pivoted to
lugs 52 extended from the frame 47. The opposite end of the frame 47 bas

page_text: pivotal connection with a link 53, the lower end of which is pivoted to a bracket 54
extended from the frame 1.
Secured within the frame 1 below the reciprocating mould-board 25, is a
table 55, having a series of openings at each end designed to register with openings
through the mould-board. At the central portion. this table 55 will form a bottom
for the mould-openings when the clay is pressed therein by means of the spiral
blades 39.
Movable at the sides of each plunger 4 and 5 are carrier chains 56. These
carrier chains are reciprocated transversely of the machine frame, and as here
shown, the chains are extended around rollers 57 mounted on the corners of
laterally disposed frames 58. Reciprocating motion is imparted to the chains 56
by means of sprocket chains 59, engaging with sprocket wheels on shafts of the
chain driving wheels and engaging with sprocket wheels 60, on the shaft 61
of which are mounted pinions 62 engaged by segment racks 63 pivoted to the
machine frame, and from which rods 64 extend to engagement with cam wheels 65
on the shaft 14.
In operation, the clay or other material to be formed will be placed in the
receptacle 36, where it will be pulverized by the fingers 38 and forced through
the grating 46 into the mould openings at one end of the mould-board; then the
cutting device will be reciprocated to sever the clay in the moulds from that
in the receptacle 36, after which the mould-board will be moved to bring its
filled moulds underneath one of the upper plungers, here shown as the plunger 2.
When in this position, the upper and lower plungers 2 and 4 will be moved to
press the material in the mould openings; then the lower plunger 4 will be moved
downward to bring its plunger heads below or substantially on the plane of the
upper stretches of the chains 56, and then a carrier or receiving rack 66 is to
be placed on the chains below the mould-board. The upper plunger 2 will then
move downward so that the plunger heads thereof will force the formed brick
out of the mould onto the carrier or rack 60; then the chains 56 will be operated
to move said carrier or rack outward to the side of the machine, where it is to
be received by a transporting device hereinafter to be described.
While this operation is taking place, clay will of course be fed into the openings
in the opposite end of the mould-board.. to be moved between the plungers 3
and 5 and operated in the manner as before described. It may be here stated,
that to prevent the sticking of clay to the plungers, the said plungers and plunger
heads should be suitably heated; they may therefore be made hollow in the usual
manner and supplied with steam.
We will now describe a means for transferring the formed bricks from the
press to a car in which the bricks are to be transported to a drying apparatus.
Arranged at the sides of the machine and in line with the chains 56, are
frames 67. There will be one of these devices at each end of each pair of chains.
but a description of one will answer for all. Mounted in the lower portion of
the frame 67 is a shaft 68, to which rotary motion may be imparted by any
desired means. Movable longitudinally of the shaft but adapted to rotate there-
with, is a sleeve 69 having a clutch section at each end, one of said sections being
adapted for engagement with a clutch section 70 loosely mounted on the shaft GS,
and with which a sprocket wheel 71 is connected. From the sprocket wheel 71
a sprocket chain 72 extends to a sprocket wheel 73 on a shaft 74. The opposite
end of the sleeve 69 is provided with a clutch section adapted to be engaged with
a clutch section on the miter pinion 75, loosely mounted on the shaft 68 and
meshing with a bevel pinion 76 on the lower end of a shaft 77 extending vertically
and having bearings in the frame 67. On the shaft 74 is mounted a pulley 78,
from which cables 79 and 80 extend around pulleys 81 and 82, and thence over
pulleys 83 and 84 at the top of the frame 67, and from these pulleys 83 and 84
the cables extend downward and connect with an elevator made in the form of an
endless carrier 85, mounted to rotate around a frame 86, from the corners of which
pins extend into channels formed in the corner posts of the frame 67.

page_text: The carrier S5 is movable around rollers on shafts having bearings in the
frame 86, and on the shaft of one set of rollers is a bevel gear 87 meshing with
a bevel gear 88 mounted to move longitudinally of the shaft 77, but to rotate
therewith. As here shown, the shaft 77 is provided with a longitudinal feather
engaging in a notch through the pinion 88.
Mounted to rotate at one side of the frame 67 is a shaft 89, which is also
mounted to move vertically of said frame. Spirally disposed on this shaft 89
is a series of outwardly extended pins 90, the spaces between which are equal
to the spaces between floors 91 of a transporting car 92, and on the lower end of
the shaft 89 is a pinion 93 having a number of teeth equal to the number of
pins 90. Adapted to engage with this pinion 93 is a dog 94, carried by a longi-
tudinally moving bar 95, at one end of which is an inwardly extended arm 96
adapted to be engaged with a carrier rack 66, as hereinafter described. From
the opposite end of the bar 95 a lever 97 extends, and is pivoted near its lower
end to the base of the frame 67, and from this lower end a link 98 extends to
a pivotal connection with a lever 99. From the other end of this lever 99 a rod 100
extends to a connection with the shaft 89.
In operation, it will be assumed that a rack 66 having a load of brick thereon,
As the said
is to be placed in the first or lowest compartment of the car 92.
rack is moved onto the elevator 85 by means of the chains 56, and as said rack
approaches the end of its movement. it will engage against the arm 96 and move
the bar 95 longitudinally. This longitudinal movement of the bar 95 will cause
its dog 94 to move the pinion 93 one step, and thus move the first pin 90 on
At this same

time the clutch section 69 will be moved into engagement with the clutch
section 70 by means of the lever 97 which extends into an annular channel formed
in the clutch section 69. When the clutch sections 69 and 70 are thus engaged,
the shaft 74 will be rotated to raise the elevator 85. When the elevator shall
have been raised sufficiently high to engage the rack 66 with the pin 90, the
shaft 89 will be moved upward, disengaging the pinion 9:3 from the dog 94, and by
pull ng up the rod 100, will rock the lever 97 to move the clutch section 69 into
engagement with the sleeve 69*. This will rotate the shaft 77. and conscquently
Dove the endless carrier 85 to force the rack 66 into the compartment of the
car. Before the movement of the carrier 85, a counter-balanced lever 1ª
fulcrumed to the frame must be released from engagement with a wheel on the
shaft of the sprocket 71. This operation will continue until all the compartments
are filled.
At the side of the frame 67 is a vertically swinging track section 101, the
outer ends of the tracks being designed to swing downward to communicate with
fixed or level tracks 102. As the car 92 is moved upward onto the track
section 101, pins 1033 extended outward from the sides of the car will engage
upon the inclined under surfaces of blocks 104 extended from the frame 67.
These inclined blocks and the pins engaging therewith will swing the car and
tracks to a horizontal position, and the coupling on the car will engage with a
coupling pin 105 of the side of the frame 67. From this coupling 105 a rod 106
extends outward and is pivotally connected to a lever 107 fulcrumed to the
frame 67.
It is designed that after a car shall have been loaded, its downward movement
will draw an empty car into position against the frame 67.
By reference to Figure 16, it is to be observed that there are two sections or
lengths of track. 102, 108. The track section 102 has its rails disposed in
alignment with the shifting rails 101, the latter being disposed adjacent to one
side of the loading apparatus so as to be occupied by a car when the latter is in
operative relation to the loading apparatus for the purpose of receiving the load
theretrom. The other track section 108 is disposed partly in parallel relation
to the track section 102 and it also has its rails inclined at one end towards the
sh'ting rails 101 for the purpose of directing a car traversing the track section 108

page_text: towards the rails 101 or rice versa. Midway between the rails of the track
section 102 is a carriage rail 109, the latter being provided at a suitable point
thereon with the trip lug 121. The other track section 108 is provided with a
central rail 110, the same being situated between and equidistant from the rails
of said track section 108. A car 92 is adapted to travel on the track section 102,
while another car 92ª traverses the track section 10S.
As
The object of this part of the apparatus is to permit empty cars on either track
section to be drawn toward the shifting rails 101 by the momentum or gravity
of the loaded car which is drawn from said rails 101 by any suitable means.
these cars must be interchanged, clutching devices are provided. Theso
clutching devices are really wheeled carriages adapted to the central rails and
each having means for connecting the same detachably to the cars 92 or 92". The
wheeled carriage for the central rail 109 of the track section 102 is shown by
Figure 15 as consisting of a suitable frame 111, which is provided with the
wheels 112, revoluble on horizontal axes, and with other wheels 113 revoluble
on vertical axes the wheels 112 being adapted to the top of the central rail 109. while
the wheels 11 travel against the vertical faces or sides of said central rail 109,
whereby the wheel carriage is prevented from swaying and is movable freely on
the rail 109. On this carriage frame is fulcrumed à vertical arm or lever 114, the
same having an upstanding end adapted to engage with a part of the frame work of
the car, such engagement being represented by the end view. Figure 12 of the
drawings. This lever 114 has a depending arm which extends alongside of the
central rail 109 which depending arm is normally in engagement with a stop 114*
on the carriage frame 111 and the trip lug 121 on the central rail 109 is disposed
in the path of the wheeled carriage. Furthermore, this arm or lever 114 is
provided with an ofstanding arm arm 115 equipped with a weight which tends
normally to hold the vertically disposed lever 114 in position for engagement
with the frame work of the car, whereby the lever 114 serves to connect the
wheeled carriage with the car. The trip lug 121 is provided on the central
rail 109 at a point some distance away from the shifting rails 101 and at the
place where the lever 114 is to be disengaged from the loaded car or to be engaged
with an empty car, whereby as the loaded car and the wheeled carriage which is
connected thereto by the lever 114, moves away from the loading apparatus, said
lever with the wheeled carriage and the loaded car will reach the point at which
the trip lug 121 is located. As this trip lug is in the path of the lower end of
the lever 114, said end rides against the lug so as to turn the lever on its pivot
and disengage its upper end from the car, whereby the lever is automatically
tripped and disengaged from the loaded car.
On the track section 108 is arranged to travel the car 92ª as hereinbefore
described, and the central rail 110 of this track section is traversed by another
wheeled carriage having the frame 116, which is equipped with the wheels 117
and other wheels 118, arranged similarly to the wheels on the other carriage.
This carriage frame 116 is counterpoised or weighted by the weight 120 and is
equipped with the clutching lever 119, the same being disposed vertically for
its upper portion to engage with a part of the frame work of the car 92ª. The
two wheeled carriages which are adapted to respectively traverse the central
rails 109, 110, of the two track sections 102, 108S are operatively connected together
by means of a cable 122, the opposite ends of which are attached to the wheeled
carriages 111. 116, in any suitable way. This cable is guided around suitable
sheaves or pulleys placed between the track rails of the track sections 102, 108,
and also between the shifting rails 101. With the wheeled carriages connected
to the cars 92, 92ª, by the levers 114, 119, respectively, the cable 122 operates
to transmit the motion of the loaded car. as it moves away from the loading
apparatus, to the empty car. for the purpose of drawing the latter up to the
loading apparatus, and when the wheeled carriage 111 is connected to a loaded
cat moving away from the loading apparatus reaches a position over the trip

page_text: lug 121, the lower end of the lever 114 rides against the lug and is thereby
disengaged automatically from its loaded car.
Instead of employing the car and gear mechanism just described, we may
employ another form of car when it is desired to carry the bricks to be piled up
in a yard. This apparatus is shown in Figures 17 and 18, in which appears
a frame 123 provided with suitable wheels movable on tracks arranged in the
yard. Mounted to rotate in this frame 123 is a long shaft 124, on which is
mounted a drum 125. This drum 125 is designed to rotate with the shaft 124,
and also to move longitudinally of said shaft. We have therefore provided the
shaft with a longitudinal feather engaged in a groove formed through the drum.
On one end of the shaft 124 is a sprocket wheel 126, from which a sprocket
chain 127 extends to a sprocket wheel 128 at the lower portion of the frame,
and on the shaft of which is a crank 129.
As a means for moving the drum 125 longitudinally of the shaft 124, we
employ a yoke 130 through an opening in which a lever 131 is movable, said
lever being fulcrumed on the top of the frame. The bricks as received from
the press are deposited in the frame 132, having a removable or slide bottom 133.
This frame or receiver 132 after having been filled with brick is designed to be
carried by the barrow 134 to a point underneath the shaft 124 of the frame 123.
When at this point the man in charge will engage the hook portions of a hoisting
frame 135 with pins 136 extended outward from the frame 132.
Movable transversely of the hoisting frame 135 is a rack bar 137, and this
rack 137 is engaged by a pinion 138 mounted on the shaft 139 having bearings
in the frame 1:35 and provided with a crank 140 at its outer end. The outer
end of the rack 137 has a downwardly extended hook arm 141 adapted to engage
with a knob 142 on the movable bottom 133. The frame 135 is connected to the
drum 125 by means of the cable 143, therefore by operating the shaft 124 by
means of the sprocket mechanism. the frame 132 carrying the brick, will be
raised from the barrow, and then by operating the lever 131, the load may be
moved along the shaft to any desired point, such for instance as indicated by
dotted lines in Figure 17. Then by rotating the shaft 139 by means of the
crank 140, the pinion 138 will move the rack 137 outward, and this movement
of the rack will also move the movable bottom 183 outward and allow the bricks
to fall onto a pile. After dumping the bricks the bottom 133 may be moved back
into position and the frame returned to the barrow 134. Before dumping the
brick however, the frame carrying the bricks should be lowered so that danger
of breaking the brick falling therefrom will be obviated.
