Improved Means applicable for use in connection with Brick
Cutting-tables.
I, EDWARD PHILIP COLLIER, of the Firm of S. & E. Collier, of Grovelands, Reading,
in the County of Berks, Brick, Tile, and Pipe Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improved means applicable for use in connection with
brick cutting-tables, for carrying, the series of cut bricks forward as fast as they are
cut by the wires, the object being to provide space between each series of bricks for
handling, whereby the transference from the boards' of the cut bricks may be
accomplished without necessitating the removal of the board itself for that purpose;
the operation being thereby expedited and the risk of damaging the bricks lessened.
In carrying out this invention, the delivery side of the cutting table is furnished
with a reciprocating, carriage arranged to work in guides in a stationary supporting
frame-work. The reciprocating carriage may be formed of angle iron connected by
end plates, and is provided with a number of pivoted weighted catches arranged to
project upwards and engage with hooks or projections on the under side of the boards
during, its travel in one direction but to pass beneath the said boards without
hindrance when travelling in the other direction. The inner end of the recipro-
cating frame is connected with a driving disc by means of a rod; motion being
imparted to the disc-shaft by. spur-gearing or equivalent means from the usual
pusher-actuating, mechanism. The motion of the reciprocating frame should be so
timed that when the pusher has arrived at the end of its out-stroke, and the cut bricks
have passed the cutting wires, the said frame is at the extremity of its in-stroke; a
slight amount of lead being given the pusher in order that the bricks may be quite
clear of the wires before the reciprocating frame commences to move; whereupon the
catches engage the projections on the under side of the boards and convey them a
predetermined distance along, the stationary, supporting frame, according to the throw
of the crank-disc. The catches are arranged at convenient distances apart in order
to afford space between the boards for the operator's hands and tools when removing
the bricks from the boards. For holding the board in position while the bricks are
being pushed thereon a pair of catches are arranged on the stationary frame and
connected with a weighted pivoted lever, the latter being operated by contact with
the reciprocating frame; the catches falling away from engagement with the board
so soon as the said frame arrives at the extent of its in-stroke. The length of stroke
of the reciprocating frame may be rendered adjustable if required.
The mechanism for actuating the pusher may be of the ordinary construction and
consist of a reciprocating slide to which the pusher is attached, the slide being
connected with a disc-wheel carried on a shaft operated from a first motion shaft
through the medium of spur-gearing. The spur-wheel on the disc-shaft may mesh

Improved Means applicable for use in connection with Brick
Cutting-tables.
I, EDWARD PHILIP COLLIER, of the Firm of S. & E. Collier, of Grovelands, Reading,
in the County of Berks, Brick, Tile and Pipe Manufacturers, 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 improved means applicable for use in connection with
brick cutting-tables for carrying the series of cut bricks forward as fast as they are
cut by the wires, the object being to provide accommodation for the bricks with a
view to the continuous working of the machine while the bricks are being wheeled
away, and to afford a space between each series of bricks for handling whereby the
transference from the " boards of the cut bricks may be accomplished without
necessitating the removal of the board itself for that purpose; the operation being
thereby expedited and the risk of damaging the bricks lessened.
The accompanying drawings illustrate apparatus for conveying the cut bricks
from the cutting-table according to my improved method; Fig. 1 being a partial side
elevation and longitudinal section, Fig. 2 a corresponding plan, Fig. 3 a view of
the left-hand end of Fig. 1, Fig. 4 a view of the right-hand end of Fig. 1 and Fig 5
a section on the line x-y in Fig. 3.
In carrying out this invention, the delivery side of the cuttting-table is furnished
with a reciprocating carriage A arranged to work in guides B in a stationary support-
ing frame-work C. The reciprocating carriage may be formed of angle iron con-
nected by end plates, and is provided with a number of pivoted weighted catches a a
arranged to project upwards and engage with hooks or projections a a¹ on the under
side of the boards or pallets A¹ during its travel in one direction, but to pass beneath
the said boards without hindrance when travelling in the other direction. The
reciprocating frame is connected with a driving disc or grooved faced cam D by means
of rods and levers d, d¹, d², d³, d. The levers d'and d² are mounted on a cross
spindle do while the lever d' is mounted on a cross shaft d; the rod d³ connecting
the pendent end of the lever d with the free end of the lever d². The lever d
carries a roller do which enters the groove in the outer face of the cam D. Motion
may be imparted to the camn-shaft D by spur-gearing or equivalent means from the
usual pusher-actuating mechanism. The motion of the reciprocating frame A should be
so timed that when the pusher E has arrived at the end of its out-stroke, and the
cut bricks have passed the cutting wires F, the said frame is at the extremity of its
in-stroke; a slight amount of lead being given the pusher in order that the bricks
may be quite clear of the wires before the reciprocating frame commences to move;
whereupon the catches a a engage the projections on the underside of the boards A¹
conveying them a predetermined distance along the stationary supporting frame

page_text: ccording to the degree of eccentricity of the cam groove (D). The catches a a are
rranged at convenient distances apart in order to afford space between the boards for
he operator's hands and tools when removing the bricks from the boards A¹. For
holding the board in position while the bricks are being pushed thereon a pair of
weighted catches a² a² are arranged on the stationary frame; the weighted portion
of each catch being provided with a lateral pin or projection a³ a³, beneath which the
ifters at a on the frame A pass when the latter arrives at the extent of its inward
travel. Or the catches may be connected with a weighted pivoted lever, the latter
being operated by contact with the reciprocating frame. These catches fall away out
of engagement with the board so soon as the frame A arrives at the extent
of its in-stroke. The length of stroke of the reciprocating frame may be rendered
adjustable if required.
The mechanism for actuating the pusher E may be of the ordinary construction
and consist of a reciprocating slide e to which the pusher is attached, the slide being
connected with a disc-wheel carried on a shaft operated from a first motion shaft through
the medium of spur-gearing; the spur-wheel on the disc-shaft meshing with the
spur-wheel pertaining to the mechanism for operating the reciprocating frame. In
the drawings, I have shown the cam D keyed on the shaft D¹ and arranged with

is keyed a pinion D. Mounted in a revoluble body or carrier D2 are two sets of
gear wheels, each set comprising a toothed wheel D³ and a pinion D4; both the
former meshing with the pinion D* while the latter mesh with a toothed wheel D5
keyed to the boss of the cam D. The body or carrier D2 as also the cam D are
respectively furnished with friction straps D6 and D7, whereby they may be held
stationary. For use in applying the strap about the wheel-carrier D2 a lever D8 and
quadrant D are provided; the lever being extended beyond its fulcrum and furnished
with a weight. The pusher E is operated by means of the levers e¹ e¹ mounted on a
cross shaft e and a lever e³; the upper ends of the levers el e¹ being connected with
the pusher by the rods et et. The free extremity of the lever e³ carries a roller e5 for

may be fitted in a slot in the outer end of the lever e³; the latter being capable of
adjustment by means of a quadrantal slot in the fixed boss e³x.
Assuming the wheel-carrier D2 to be held stationary by means of the friction-
strap Do, upon motion being imparted to the pulley D° and pinion D the sets of
gearing D3 D4 become operative and effect the rotation of the toothed wheel D5 and
the cam D. Thus the pusher E and the reciprocating carriage A are caused to
approach the cutting-table; the pusher urging the clay to pass the cutting wires,
while the catches a² a² are released by the lifters at a on the reciprocating frame A,
the catches a a engaging with the projections a¹ a¹ on the board A¹. "Upon the
further rotation of the cam D the pusher and reciprocating frame recede from the
cutting-table; the latter taking with it the board A¹ containing the newly cut bricks.
It will be apparent that these boards may be manipulated with facility and without
risk of damaging the bricks deposited thereon. The apparatus is brought to a dead
stop by releasing the strap D whereupon the gear wheels D3 D4 rotate about the
toothed wheel D5. The weight on the lever D8 however tends to depress the inner
end of that lever with the effect that the friction-strap D7 becomes tightened about
the circumference of the cam D and serves as a brake to the mechanism. By the
arrangement of reducing gear above described, wherein the small (high speed)
Opinion Dx rotates upon the shaft D¹ and transmits motion by means of the sets of
wheels and pinions D3 D4 carried by a body D2, capable of being held stationary, to
the larger (low speed) toothed wheel D', integral with the double grooved face cam D,
the velocity between the working surfaces is reduced.
The faces of the cam D may be cast separately and fitted together as shown in the
5 drawing, slots D10 being provided for allowing of any slight adjustment between the
two faces.
