Improvements in and relating to Machines for Moulding Bricks.
I, THEODOR GRIESEMANN, of 24, Schoppensteg, Magdeburg Neustadt, Germany,
Brick-Kiln Owner, 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:-
1
My invention relates to an improved machine for first mixing and preparing
clay and other earths and materials, and ultimately moulding same for the
manufacture of bricks, its object being to provide means whereby the brick com-
pound is more smoothly and intimately mixed than obtains in the machines
hitherto used thus producing better and smoother faced bricks.
My invention is fully illustrated in the accompanying drawings, in which
Fig. 1 is a side elevation, (partly in section) while Fig. 2 is a section upon the
lines A B and viewed from left to right.
My invention consists of a hopper or receptacle A into which the roughly
mixed clay and other material is first placed, the said material being received
upon a pair of steel or other rollers B, the shafts of which are carried on bear-
ings a, and one of the said shafts carries upon one of its ends a toothed wheel C,
which gears with a like wheel D upon a shaft E, supported upon a standard b,
and driven by pulleys F F, by any convenient or available power.
The hopper or receptacle A also carries a shaft G, one end of which extends
through one side of A and has mounted thereon a toothed wheel H, in gear with,
and receiving motion from a toothed wheel J, mounted upon the shaft E. The
opposite end of the shaft G extends through A and is borne by a standard c,
and surrounding this end of G are any desired number of fixed splayed or coned
boxes such as KK, the final or end one of which K' being perfectly parallel,
and has upon either or both sides noses or projections L L', a rectangular open-
ing M in each of which permits the discharge of the prepared material in the
shape and formation of bricks, the said projections and their openings being
shewn in position in Fig. 2 and by dotted outline in Fig. 1.
Upon the shaft G are mounted and fixed any number of knifes or blades N,
so placed, that while operating to mince and intimately mix the materials
under treatment, they also operate to feed and force the said material to and
through the nosings L L', from which it would emerge in the shape of a brick
to be cut and treated in the usual way, and upon such of the said blades N as
would be upon the shaft G within the hopper A, the material would first fall
after leaving the rollers B, while such of the blades as are within the boxes KK
are fixed so as to rotate within the widest ends of these.
The rotation of the shaft G may, if necessary, be accelerated by the means
of an additional toothed wheel H¹, mounted thereon, and in gear with a toothed
wheel J', mounted upon a shaft E¹, and operated by pulleys F¹ F¹ set in motion
by the same motive power as that actuating the pulleys F F.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The improved mixing and moulding machine for brickmaking, substan-
tially as described and shewn.
2nd. The improved mixing and brick moulding machine consisting of a
hopper or receiver A carrying rotating rollers B B, operated by suitable gearing,
actuated by a shaft E, the said shaft E by the means of suitable gearing also
operating to rotate a shaft G, passing through A, and a series of coned or splayed
boxes such as K, the said shaft G carrying any number of blades or knifes N,
for cutting mixing and driving the prepared material through the said boxes K
into a box K', and through rectangular apertures M therein, substantially as
herein described and shewn..
