Improvements in Apparatus for use in Oramming or Feeding
Poultry.
I CHARLES EDWARD HEARSON of No. 5 Templar Street Camberwell in the County
of Surrey Engineer do hereby declare the nature of this invention and the manner
in which the same is to be performed to be particularly described and ascertained in
and by the following statement:—
My invention consists of the improvements hereinafter described in apparatus for
use in "cramming" or feeding poultry.
In the following description the accompanying Drawings are referred to by the
letters and figures marked thereon.
Figure 1 of the said drawings is an elevation of the said apparatus partly in
section. Figures 2 and 3 are sections showing portions of the said apparatus drawn
to a larger scale than Figure 1 the section Figure 2 being taken on the line A A
Figure 1 and the section Figure 3 being taken on the line B B Figure 2. Figure +
is a detail hereinafter referred to. The same letters and figures of reference indicate
the same parts in the several Figures of the Drawings. In all the said Figures
the parts of the apparatus are shown in the positions which they occupy when the
apparatus is not being used. a is a receptacle for containing the food. is a cylinder
The said parts a baro
to which the receptacle a is secured by screws a' a'.
supported by legs c c² c³ which constitute the stand of the apparatus and are connected
by bolts to lugs b' 6' formed on the cylinder 6 the said legs being braced together
by bars of hoop iron c c c c. A portion only of the leg c² and portions only of
the bars c c c are shown the said leg c² being shown partly broken away in order
to exhibit the parts of the apparatus behind it. To the leg ca wheel d is connected
by plates or brackets (one of which is shown at d Figure 1) the object of which
wheel is to facilitate removal of the apparatus. e is a tubular piston arranged
within the cylinder b. f is a treadle jointed to the brackets d' at " and working
between guides consisting of bars of boop iron secured in an upright position to the
bars cone of which upright bars is shown in Figure 1 and marked c. 1 is a
strap secured to the treadlo for the purpose hereinafter explained. is a rod jointed
to the treadle and passing through the axis of the tubular piston e.
secured to the rod g above the said piston which valve when the said rod is descending
rests on a seating formed at the upper part of the said piston and closes the upper
end of the orifice therein and is a boss having arms formed on it and secured to the
said rod 9 below the piston which arms when the rod g is rising bear against the
underside of the piston e as shown in Figure 3. The shape of the said arms is shown
in Figure 4 which is a plan view of the part i drawn separately. ; is a cavity
formed in the bottom of the cylinder band is an orifice in the said cylinder
communicating with the said cavity and with a nozzle k having a flexible tube!
secured to it through which orifice and nozzle and tube the food is ejected when the
piston is depressed. m is a spring which tends to keep the treadle in the position
the
shown in Figure 1. n is an adjustable stop secured by a set screw n¹ on the rod
position of which stop determines the extent of stroke of the piston in the
cylinder a.
h is a valve
The method of using and the action of the said apparatus are as follows:-
I
The food required to be used is placed in the receptacle a and a portion of the
said food passes down between the valve hand piston e through the hollow of the
said piston and between the arms on the boss i into the part of the cylinder below
the said piston. When the said part of the cylinder is filled with food which has
thus passed down the apparatus is ready for use.
One of the birds to be crammed is then held in a convenient position and the

page_text: tube is passed into its gullet and the treadle f is depressed and then released.
Another bird is then taken and the tube is passed into its gullet and the treadle is
again depressed and released and so on. During the depression of the treadle the
following actions take place. The valve first descends until it rests on the seating
formed around the upper part of the tubular piston e thus confining the food in the
cylinder below the said piston. The continued motion of the treadle f then causes
the piston to descend with the rod g. and valve h until the motion of the said parts
is stopped by contact of the boss i and the arms thereon with the bottom of the
cylinder. By these motions of the said parts the food in the cylinder is forced out
through the orifice nozzle and tube into the gullet and crop of the bird. On
the treadle being released the spring m draws up the treadle causing the rod g
to rise until it is in the position shown in Figure 3. During the upward motion of
the said rod the following actions take place. The valve his first raised from its
seating on the piston e and moves upward without raising the piston until the arms
on the boss bear against the underside of the said piston when it is caused to rise
with the rod and pass into the food above it which then descends through the space
between the valve and the upper end of the piston and through the hollow in the
piston and between the arms on the boss into the portion of the cylinder below.
The quantity of food ejected at each downward stroke of the treadle is regulated by
adjusting the height of the stop n' on the rod g. Where the food used is too thick
to descend readily by gravity from the receptacle a past the valve and piston e
into the cylinder 6 the space below the said piston may be filled before beginning
to use the apparatus as hereinbefore described by depressing the treadle several times.
If for any reason the resistance to the upward motion of the parts connected to the
treadle be too great for the spring m to overcome the treadle may be drawn upward
by the foot which is passed under the strap" for that purpose.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that I
claim
:
First The arrangement of the cylinder of poultry cramming apparatus in a
vertical position below the food receptacle and the direct connection of the rod by
which the piston is actuated to a treadle arranged below the said cylinder.
Secondly-The arrangement hereinbefore described and illustrated in the
accompanying Drawings for permitting the contents of the food receptacle to pass
to the part of the cylinder below the piston while the said piston is rising or is at
the end of its upward stroke and for preventing the contents of the cylinder from
passing the piston while it is descending the said arrangement consisting of a valve
secured to the upper part of the rod by which the piston is actuated and of arms or
the equivalent thereof secured to the said rod below the said valve the said valve being
above the piston and the said arms being below it and free from or unconnected with
the piston.
:
Thirdly The arrangement herein before described for regulating the quantity of
food ejected from poultry cramming apparatus by the action of the mechanism thereof
that is to say the combination of an adjustable stop with the rod by which the piston
is actuated.
Fourthly The general combination and arrangement of parts constituting the
poultry cramming apparatus hereinbefore described with reference to the accompanying
Drawings.
