PROVISIONAL SPECIFICATION.
An Improved Poultry Cramming Machine.
We, HENRY NEVE and FREDERICK NEVE, both of Warbleton, in the county of
Sussex, Millwrights, and Engineers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to an improved machine for cramming poultry.
The improved machine comprises a chamber or cylinder mounted upon a stand and
provided at or near one end with a hopper through which the food is introduced, while
the other end has formed upon or attached to it a nozzle through which the food is
discharged into the crops of the birds.
Within the chamber or cylinder is a reciprocating piston or plunger containing a
valve which is adapted to open as the piston is moved backward to allow the food to
pass to the front of the said piston, but which closes as the piston is moved in a
forward direction.
The said piston or plunger is preferably operated by means of a treadle the motion
of which is communicated to the said piston or plunger through the medium of suitable
rods and levers.

⚫COMPLETE SPECIFICATION.
An Improved Poultry Cramming Machine.
We, HENRY NEVE and FREDERICK NEVE, both of Warbleton, in the County of
Sussex, Millwrights and Engineers, 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 an improved machine for cramming poultry.
The improved machine comprises a chamber or cylinder mounted upon a stand and
provided at or near one end with a hopper through which the food is introduced, while
the other end has formed upon or attached to it a nozzle through which the food is
discharged into the crops of the birds.
Within the chamber or cylinder is a reciprocating piston or plunger containing a
valve which is adapted to open as the piston is moved backward to allow the food to
pass to the front of the said piston, but which closes as the piston is moved in a forward
direction.
The said piston or plunger is preferably operated by means of a treadle the motion
of which is communicated to the said piston or plunger through the medium of suitable
rods and levers.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawing, in which—
Figure 1 is a sectional elevation of our improved apparatus; and
Figure 2 is a plan view of the upper part of the same detached from the stand.
Figure 3 is a view of the piston or plunger drawn to an enlarged scale; and
Figures 4 and 5 are views of details of the same.
a is the stand upon which the apparatus is supported, the said stand being advan-
tageously provided on one of its legs with a wheel to facilitate the movement of the
apparatus from place to place.

bearings e, e, formed in brackets f, ƒ projecting from the plate 9 secured to the upper
end of the stand a.
his the hopper through which the food is introduced into the chamber C, and i is
the nozzle through which the food is discharged.
& is the piston or plunger, which is adapted to be reciprocated to and fro in the
chamber c by means of the treadle 1, through the medium of the connecting rod m
and the bell-crank lever n. o is the valve with which the said piston or plunger is
provided, the said valve being adapted to slide on a rod p secured to the end of the
piston-rod, as indicated most clearly in figure 4, where the valve is shown in full lines
against its seat and in dotted lines away from the seat.
The operation of the apparatus herein before described is as follows:-
Assuine the piston to be in the position shown in figure 1, if now, food is
introduced through the hopper into the barrel c, and the treadle is raised to the
position indicated in dotted lines in figure 1, (the foot being placed in a loop g
on the said lever) the piston will be drawn backwards, so that the food in the cylinder
will pass the valve o: when the treadle is again depressed the valve is automatically
closed and the food in the chamber or cylinder is forced through the nozzle i; a fresh
charge at the same time flowing into the cylinder through the hopper ; the operation
is then repeated.
The object of mounting the cylinder c upon trunnions is to allow of the slight
oscillation which takes place during the reciprocation of the piston through the
medium of the bell crank lever n.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
wo claim is —
1. In a poultry cramming machine, the combination of a cylinder provided with a
hopper for the introduction of food into the said cylinder; a nozzle through which
such food is discharged, and a piston reciprocating in the said cylinder and provided
with a valve, all substantially as, and for the purpose, described.
2. The improved poultry cramming machine hereinbefore described and illustrated
in the accompanying drawing.
