A New or Improved Transportable Brick Press.
LEWIS BENSON KENNEDY of 138 Percy Road Shepherds Bush 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
The characteristic features of this machine are its simplicity and its portability
notwithstanding which a very high pressure can be simultaneously applied on the
top and on the bottom of the clay in the moulds at one stroke of a lever actuated
with the aid of a connecting rod by a crank wheel provided with teeth.
In the accompanying drawings Fig. 1 is a side view and Fig. 2 a front view of
my improved brick press.
This press consists of two upright frames H connected together by the axis e²
and the mould table I. and bolted to a wooden beam or other part or piece.
In the two moulds formed in the said table operate four rams, two upper rams B.
and two lower rams C. furnished with pressure plates n whereby the clay is
compressed in the moulds m being fed therein by the charger k which receives same
from the hopper J above and is moved to and fro by the levers P. & Q actuated
through the roller by the cam O formed in the front side of the disc W the
lever being pivotted on the bracket b:
The rams are carried by the blocks D & D respectively which slide up and down
within planed guides g formed in the frames H in the shape of recesses. The
block D' is compressed by the block D² connected by the pins or trunnions e¹ to the
two upright connecting rods E. which are pivotted at e to the lever A; the latter is
fulcrumed on the pin e carried by the frames H and is jointed at one end at e² to
the upper end of the toggle joint T the lower extremity of which is connected to
the upper block D so that the lever A actuates the upper rams B by the aid of the
toggle joint T and the lower rams C by that of the vertical connecting rods E and
of the block D'.
The outer end of the lever A is connected at f to the pitman or connecting rod F
pivotted to the crank pin at d of the toothed wheel M which is mounted on the
shaft V and set in motion by a pinion mounted on the engine shaft (not shown).
Upon the rear side of the disc W is formed a cam path S. bearing against the
rollers which is carried by one end of the lever p fulcrumed on the axis h supported
by the extension of the frame H while its other end enters the open part of the
ram block D' (Fig. 2) wherein.it is pivotted to a pin z.
The drawing shows the rams in compression some of the parts in dot and dash
lines are in the reverse position i.e. when the upper rams are raised and the lower
rams lowered.
After compression, the block D' is lowered by the rods E and the rams are
pushed up into the moulds m owing to the action of the cam path s, the plates n
forcing the compressed bricks out of the moulds and up to the level of the mould
table whereupon the charger moved forward by the cam O pushes the said bricks
along to the left hand side of the table I in order to fill the moulds afresh, the
lower rams meanwhile returning to their original position. On the charger k being
subsequently withdrawn compression takes place again.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that what I
claim is :-
1. In brick presses, applying the compression simultaneously on the top and on

page_text: the bottom of the clay, wherewith the brick is formed, at one stroke of a lever
actuated through a connecting rod by a crank disc keyed on the main shaft, by
means of upper rams connected to a toggle joint actuated by the said lever, and of
lower rams actuated by the same lever through a block and two connecting rods or
bars, substantially as herein described and shown.
2. In brick presses the combination of the frames, the upper and lower rams and
the lowermost block with a crank disc having a cam on one side and a cam path
on the other, and with a toothed crank wheel both mounted on the main shaft of
the machine substantially as herein described and shown.
