An Improved Poultry Cramming Machine,

page_text: PROVISIONAL SPECIFICATION.
An Improved Poultry Cramming Machine,
I, SIDNEY HERBERT BATH, of 165, Gray's Inn Road, in the County of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object an improved and simple construction of poultry
cramming machine which is reliable in its action and not liable to get out of
order whilst the operating mechanism is so arranged as to afford space within
the frame of the machine to contain a receptacle to hold a reserve supply of food
or to hold other desired article.
Heretofore poultry cramming machines have been constructed with a receptacle
for the food and with either a horizontal or a vertical cylinder below such
receptacle within which cylinder a compound piston or plunger has been worked
to receive the food and to force it through the feeding tube. In these con-
structions the food in the receptacle has had to flow through a comparatively
small passage to the cylinder and was consequently liable to obstruction from
various causes.
According to my invention I employ a food receptacle at the lower part of which
is an opening leading to the feeding tube. Within the said receptacle at the
lower part thereof is a cylinder open at the bottom and fitted with a piston or
driver. The cylinder is of such diameter as to embrace the feed pipe opening
within its circumference and such cylinder and piston are connected to a rod
passing downwardly through a stuffing box in the bottom of the food receptacle.
The cylinder and piston are so operated that the cylinder is first caused to
descend so as to gather and confine within its area a quantity of food which has
ready access to the underside thereof entirely around its circumference.
When the open bottom of the cylinder has arrived at the bottom of the food
receptacle the piston which has remained unmoved till then is caused to descend
and thereby force the food, which has been enclosed within the cylinder, out
through the feeding tube. The cylinder and piston are then caused to rise to
enable a fresh charge to pass to the bottom of the receptacle in readiness for a
fresh operation.
The rod connected to the cylinder and piston is preferably connected at a short
distance below the food receptacle to a lever, one end of which is pin jointed to
one leg of the framing whilst the other end is suitably guided and is connected
to a treadle by which it can be operated.
This arrangement leaves the space enclosed by the lower part of the framing
free to receive a food reserve receptacle or other desired article.

I, SIDNEY HERBERT, BATII, of 165, Gray's Inn Road, in the County of London,
Manufacturer, 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 invention has for its object an improved and simple construction of poultry
cramming machine which is reliable in its action and not liable to get out of
order whilst the operating mechanism is so arranged as to afford space within
the frame of the machine to contain a receptacle to hold a reserve supply of food
or to hold other desired article.
Heretofore poultry cramming machines have been constructed with a receptacle
for the food and with either a horizontal or a vertical cylinder below such
receptacle within which cylinder a compound piston or plunger has been worked
to receive the food and to force it through the feeding tube. In these con-
structions the food in the receptacle has had to flow through a comparatively
small passage to the cylinder and was consequently liable to obstruction from
various causes.
I will describe my invention with the aid of the accompanying drawings, in
which:-
b
Fig. 1 is a side elevation of my improved poultry cramming machine, and
Fig. 2 is a vertical section of the food receptacle and parts related thereto.
According to my invention I employ a food receptacle a at the lower part of
which is an opening 6 leading to the feeding tube c. Within the said recep-
tacle a at the lower part thereof is a cylinder d open at the bottom and fitted
with a piston or driver e. The cylinder is of such diameter as to embrace the
feed pipe opening 6 within its circumference and such cylinder d is free to slide
on the rod f to which the piston e is connected; the amount of travel of the
cylinder with relation to the piston e to increase or decrease the charge of
food, is regulated by a coiled spring e¹ surrounding the rod f one end of this
spring e¹ bears on the top of the cylinder d and the other end bears against the
lower side of a winged nut fl mounted on the screwed upper end of the rod f,
this rod fpasses downwardly though a stuffing box g in the bottom of the food
receptacle a,
The cylinder d and piston e are so operated that the cylinder d by the action of
the spring el is first caused to descend with the piston relatively stationary therein
so as to gather and confine within its area a quantity of food which has ready
access to the underside thereof entirely around its circumference.
Then when the open bottom of the cylinder d has arrived at the bottom of the
food receptacle a, the spring e¹ yields and the piston e which has hitherto remained
unmoved, with relation to the cylinder d is caused to descend therein and thereby
force the food which has been enclosed within the cylinder d, out through the
feeding tube c. The cylinder d and piston e are then caused to rise to enable a
fresh charge to pass to the bottom of the receptacle a in readiness for a fresh
operation. The top of the cylinder d is perforated at d to allow any air in the
cylinder to escape and prevent it from being forced into the feeding tube c along
with the food.
The rod is preferably connected at a short distance below the food receptacle a
to a lever one end of which is pin jointed at h¹ to one leg of the framing
whilst the other end is pinjointed at 2 to the operating treadle link or lever j
which passes through a guide on the frame i. The treadle mechanism
returned by the spring h³.

The framing is provided with a wheel 23 and handles 23 for convenience in
moving the machine from place to place.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to performed I declare that what
I claim is:-
-
!
1. A poultry cramming machine consisting of the combination with a food
receptacle having in its bottom an opening leading to the feeding tube, of a
movable cylinder open at the bottom and capable of enclosing within its circum-
ference the food delivery opening, a piston fitting within said cylinder, a rod to
which said piston is fixed, a stuffing box in the bottom of the food receptacle
through which the piston rod passes, an adjustable spring surrounding said piston
rod and bearing against the top of the cylinder and against a fly nut on the
screwed upper end of the piston rod, a lever connected to the piston rod at a
short distance below the bottom of the food receptacle and a treadle lever or
link connected to said lever substantially as herein set forth.
2. A poultry cramming machine consisting of the combination with a food
receptacle having in its bottom an opening leading to the feeding tube, of a
movable cylinder open at the bottom and capable of enclosing within its circum-
ference the food delivery opening, a piston fitting within said cylinder, a rod to
which said piston is fixed, a stuffing box in the bottom of the food receptacle
through which the piston rod passes, an adjustable spring surrounding said
piston rod and bearing against the top of the cylinder and against a fly nut on
the screwed upper end of the piston rod and means for operating said piston and
piston rod substantially as herein set forth.
3. In a poultry cramming machine, the combination with a food receptacle
having in its bottom an opening leading to the feeding tube, of a movable
cylinder open at the bottom and capable of enclosing within its circumference the
food delivery opening, a piston fitting within said cylinder, a rod to which said
piston is fixed, an adjustable spring surrounding said piston rod and bearing
against the top of the cylinder and against an adjustable stop on the piston rod
and means for operating the piston and cylinder substantially as herein set forth.
