Improvements in the Method of and in Apparatus or Machinery for
Moulding and Pressing Bricks and the like.
I, WILLIAM ARTHUR GILL, of 22, Leyburn Terrace, Beeston Hill, in the City of
Leeds, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention consists in the combination of adjustable rolls (Huted, plain, or
otherwise) for feeding the clay or material through a spout or mouthpiece opposite
which is a rotary cylinder having a series of moulds, with a cutter for cutting off the
required length of clay or material for each mould, as the cylinder rotates to bring
each mould opposite a plunger which is operated by crank, disc, or other suitable
means. The said cylinder and rolls are so geared that when the rolls are forcing the
material forward into and through the mouthpiece and into the mould the cylinder
is stationary and vice versa, or the said rolls may be arranged to rotate at the same
time as the cylinder, and not intermittently, as before described. The said rolls
are arranged to work in a horizontal direction, in which case the pressing action
is obtained vertically, or the rolls and mouthpiece with cutter may be arranged
vertically, and have combined with them reciprocating moulds acting horizontally,
and with plungers and gearing for giving the pressing action.
The apparatus or machine is driven from a main shaft with suitable gearing for
operating the moveable parts.

I, WILLIAM ARTHUR GILL, of 22, Leyburn Terrace, Beeston Hill, in the City of
Leeds, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention consists in the combination of adjustable rollers, the circumferences
of which may be fluted, plain or otherwise for feeding the clay or other material into
and passing it through a spout or mouthpiece, opposite to which may be a rotary
IPmine 21

page_text: cylinder having a series of moulds. Into one of the moulds the clay or like material
is forced by the said feed rollers whilst the cylinder is stationary, the cylinder is then
rotated some distance into position for further compressing the clay or the like in
the mould by a plunger operated by a crank, disc or other suitable means.
The said cylinder and feed rollers are so geared, that when the rollers are forcing the
material through the mouthpiece into the cylinder mould opposite the mouthpiece,
the cylinder is stationary and vice versa, or if desired the rollers may be arranged to
rotate continuously and not intermittently.
The feed rollers are mounted horizontally one above the other, in which case the
feeding hopper is at one end of the machine and a further pressing action of the
material in the cylinder mould is arranged vertically; or as will be readily understood,
by arranging the hopper and feed rollers at the top of the machine, the material will
be fed to the spout or mouthpiece vertically, and the further pressing action of the
material in the cylinder mould is then in a horizontal direction; or my object may
be accomplished by dispensing with the cylinder and utilizing a reciprocating mould
in place of the cylinder mould.
In describing my invention in detail reference is made to the accompanying
sheet of drawings, in which
Fig. 1 represents a plan of a machine constructed according to my invention.
Fig. 2 is an end elevation of the same.
Fig. 3 a side view with standard for supporting main shaft, the driving pullies and
side frame of the machine removed for more clearly illustrating the working parts.
Fig. 4 is a detached detail side elevation showing the cylinder, spout or mouthpiece,
feed rollers and hopper, partly in section.
Fig. 5 is a modified arrangement having a reciprocating mould instead of a cylinder
mould, shown partly in section with the driving pullies and side frame removed for
inore clearly showing the working parts, and
Fig. 6 is a plan.
The machine is driven by one of the pullies A secured on shaft B, to which is also
secured a pinion C gearing into spur wheel D mounted upon shaft E, upon the
opposite end of which is secured a disc plate F with a stud & attached thereto, and
on the said shaft is also secured a wheel H having by preference some of the teeth
cut away as shown, by which an intermittent motion is imparted to the spur wheel J
secured on the axle J¹ of bottom feed roller B¹, and on the said axle is secured
another spur wheel K gearing into wheel K¹ secured on the axle of top feed
roller B².
Gearing with the pinion C is a spur wheel L secured on crank shaft M on which is
mounted a connecting rod N for operating the plunger O and on the said shaft is
secured a cam plate P for operating the vertical rod Q and lever Q'.
The clay or other material from which the bricks are formed is deposited in
hopper R, the sides encasing the ends of the rollers B1 and B2, the circuinference of
which may be plain, corrugated or of other suitable configuration. The side plates of
the hopper R continue to the spout or mouthpiece S through which the clay or the
like is forced by the rotation of the feed rollers B1 and B2 into one of the moulds T
in intermittent rotating cylinder T, arranged with plungers in the manner as
hitherto.
When a mould T is filled with clay or like material, on the stud G arriving in the
position shown by Fig. 3, engaging with one of the slotted openings Fi in star
wheel F, the mould cylinder T is caused to rotate one fourth of a revolution, thus
bringing the mould containing the clay or the like from opposite the spout or mouth-
piece S to the top under the reciprocating plunger O, by which the material in the
mould is further compressed, on the downward stroke of the said plunger; on the
return of which, the pressed material in the mould is raised some distance by the cam
plate P operating the lever Q¹, the connections between the said cam plate and
lever and the plunger within the mould cylinder T" being of the ordinary description.
The compressed clay or other material is further ejected, either entirely or partly from
the mould T on to the table U by the operation of the before mentioned ordinary

page_text: plunger within the cylinder T actuated by the filling of the opposite mould with clay
or other material at the end of spout or mouthpiece S in the manner as hereinbefore
described.
It will be obvious to persons skilled in the construction of brick moulding machines,
that by arranging the hopper at the top into which the clay or other material is fed to
the machine, and the feed rollers and other mechanism in the same relative positions,
the spout or mouthpiece S would then be vertical so that the clay or the like
would pass through the spout or mouthpiece to the mould cylinder T" placed beneath
the same,
the whole of which would be operated substantially in the manner as
herein before described.
My object of moulding bricks by feeding the clay or other material to the mould
by the action of the feed rollers B1 and B2, may be accomplished by utilizing a
reciprocating mould such as shown by Figs. 5 and 6 in which like parts to those
herein before described are indicated by similar letters indicating the several parts of
the rotary mould cylinder machine.
In this case the clay or the like is fed from the hopper R, passes between the
rollers B1 and B2 to the spout or mouthpiece S arranged with adjustable sliding
pieces V and W at the respective ends for keeping the ends of the said spout or
mouthpiece in contact with the rollers B1 and B2. The sliding mould box is supported
by the rollers Z and reciprocated by the crank shaft M operated from the main
shaft B through the spur gearing shown by Fig. 6.
The clay or the like is forced through the shoot or mouthpiece S, into a mould box,
two boxes are arranged in the same reciprocating block as shown by the drawing, the
mould Y being under the shoot S for receiving the clay or like material, and when in
this position the ends of the mould are stopped by stationary end plates forming
part of the casing through which the mould box slides. On the rotation of the
crank shaft M the mould Y is moved into the space S¹ for the removal of the moulded
brick endwise from the mould in any convenient manner; nould Y¹ will then be
under the shoot or mouthpiece S for receiving the plastic clay or the like which is
removed from the mould on the return of the crank M and mould box into the
position shown.
I am aware that rotary feed rollers have been used for forcing plastic clay into
revolving moulding cylinders, such arrangement is shown and described in the
Specification of Gibson No. 1142 of 1856, and in the Specification of Fawcett
No. 9337 of 1890, and I make no claim thereto, or anything described and claimed
therein.
Having now particularly described and ascertained the nature of this in-
vention, and in what manner the same is to be perforined, I declare that what I
claim is
In a brick making machine the combination of the star wheel F2 with a mould
cylinder T¹, cam plate P and lever Q1, arranged substantially in the manner and for
the purpose as herein before set forth.
