Improvements in Apparatus for Feeding Calves.
We HENRY BOWMAN LINGFORD and EDWARD LINGFORD, Farmers, of
North Road, Ripon, Yorkshire do hereby declare the nature of this invention to
be as follows:-
"
This invention consists of a mouthpiece formed of a short length of " pressure
india rubber tubing of suitable length & thickness, the same being connected with
a suitable length of ordinary rubber tubing by means of a hard wood handle which
is bored longitudinally to receive the both tubes, one from either end of the same.
A hole is formed in the partition or door of the house in which the animal is
confined, such hole being furnished with a metal ring tapering towards the inside in
which is inserted the hard wood handle the latter tapering at one end to fit the
ring, and in which position it is secured by means of a spring or springs that can be
released only from the outside-so that when the mouthpiece tube is being
passed through the ring the handle becomes automatically locked in the same.
The length of ordinary rubber tubing terminates at its other or free end in a
widened out rubber funnel having its extreme edge bounded by a hermetically
sealed circular tube. This end of the tube is weighted by an enclosing cone shaped
piece of enamelled metal open at the base having holes formed in the upper portion
thereof, and slots formed in its base, the same being to allow milk or other liquid
to reach the funnel termination of the rubber tube within the metal cone.
This end of the tube with its metal cone is lowered to the bottom of a pail of
milk, and until the milk is exhausted it passes freely through the holes of the metal
cone and up through the tube, but immediately upon the milk being all drawn away
from the pail the rubber funnel sticks tightly to the bottom of the pail forming &
pneumatic seal and preventing the animal from sucking in air. The spring in the
door opening is then released the handle with the mouthpiece attached is withdrawn,
and the whole apparatus can be immersed in water for cleansing.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Feeding Calves.
We, HENRY BOWMAN LINGFORD and EDWARD LINGFORD, Farmers, both of
North Road, Ripon, 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 consists of a mouthpiece formed of a short length of india rubber
tubing of suitable length and thickness, the same being connected with a suitable
length of ordinary rubber tubing by means of a hard wooden connection which is
bored longitudinally and receives both tubes, one at either end. A hole is formed
in the partition or door of the house in which the animal is confined, such hole'
being furnished with a metal ring tapering towards the inside, in which is inserted
the hard wooden connection or plug, the latter tapering at one end to fit the ring.
This plug is secured in position by means of a spring or springs that can be

page_text: released only from the outside, so that when the mouthpiece tube has been passed
through the ring, the plug becomes automatically locked in the same.
The length of ordinary rubber tubing terminates at its other or free end in a
widened out rubber funnel, having its extreme edge bounded by an hermetically
sealed circular tube. This end of the tube is weighted by an enclosing case of
enamelled metal, open at the base, having holes formed in the upper portion
thereof, and recesses formed in its base, the same being to allow milk or other
liquid to reach the termination of the rubber tube within the metal case.
This end of the tube with its metal case is lowered to the bottom of a pail of
milk, and until the milk is exhausted it passes freely through the holes of the metal
cone and up through the tube, but immediately upon the milk being all drawn
away from the pail, the rubber funnel sticks tightly to the bottom of the pail,
forming a pneumatic seal and preventing the animal from sucking in air. The
spring in the door opening is then released, the handle with the mouthpiece
attached is withdrawn, and the whole apparatus can be immersed in water for
cleansing.
In order that this invention may be more clearly understood, reference is had to
the accompanying sheet of illustrative drawings, in which
Fig. 1 is a longitudinal section of the mouthpiece and attached parts,
Fig. 2 a cross section and Fig. 3 an end view of the mouthpiece,
Figs. 4 to 7 vertical sections of the valve arrangement to be placed in the
receptacle for the milk.
A is the indiarubber mouthpiece, having three small internal tubes A', and a
small hole or slit at the end. These tubes serve to give greater resiliency to the
mouthpiece, causing it to act somewhat as a valve, the animal alternately com-
pressing and releasing it in the action of sucking, so that when released it expands
and draws up milk into it. The tube A is fixed to the plug B in any suitable
manner, this plug being pierced with a central hole, and having a tapered end, which
fits into the ring C screwed or otherwise fixed in the wall of the house containing
the animal. This ring has its inner surface tapered to correspond to the end of the
plug, and is provided with a flange C¹ at its outer end. On the plug B is fixed the
spring D, the end of which forms a catch which takes against the inner side of
the flange C¹, so that when the plug and mouthpiece are pushed through the ring,
the spring catches and locks the arrangement in position. Fixed in the plug, and
passing through its central hole, is the tube E, leading to the pail and forming a
communication from the valve. This tube has at its end the flexible disc F, with
annular flange F¹ of similar material, enclosed in a case or cover G, having one or
more holes G¹ at top, and standing on legs G³, formed by cutting the case away at
bottom. The tube E passes through this case, and as shown in Figs. 4 and 5, is
provided with indiarubber rings E' fixed to it, and attaching it to the case.
In Figs. 6 and 7, a small valve H is shown, the tube E being cut and the valve
placed on the small piece E¹, enclosed in the stouter tube J, which fastens it to the
cover. This valve is designed to prevent the liquid after it has entered the tube,
returning to the receptacle, but this arrangement is not necessary. Figs. 4 and 6
show the valve in its ordinary position when milk is in the pail, and Figs. 5 and 7
show it when the milk has been exhausted, and suction is applied, causing the
disc F to be drawn down on the bottom of the pail and close the entrance to the
mouthpiece. The milk enters the tube through the holes G¹ and the recesses at
the bottom of the cover G.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
(1) A calf feeding device, comprising a mouthpiece A, a plug B, adapted to be
fastened in the wall of the house containing the animal, a connecting tube. E, with
disc F and cover G, substantially as described and for the purposes specified.

page_text: (2) An improved device for feeding calves constructed and operating sub-
stantially as described and illustrated in the accompanying drawings and for the
purposes specified.
