An Improved Apparatus for Facilitating the Milking of Cows.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a milking apparatus which is applied to the nipples of
the cow and effects the milking by a pressure commencing at the upper part of the
nipples and gradually descending to their lower extremity, which enables the opera-
tion to be performed easily and conveniently.
The improved milking apparatus constructed according to the said invention
comprises a box which is open at the top, and contains two helices secured upon
separate rotary shafts. The shafts are rotated by means of toothed wheels, a shaft
and crank. In the rotary movement the helices exert a periodically recurring
pressure upon a freely suspended pad which is flexible in all its parts, so that the
pressure begins above and gradually descends to the lower end. This pressure first
ceases above, but is continued downwards and immediately afterwards ceases here
also. During the remaining part of the revolution of the helices they do not act
upon the nipples so that these are freely suspended and have time to be filled again
with milk.
For producing the aforesaid pad I preferably use a number of brass rods which
are connected with each other by rings and covered on the side turned towards the
nipples with a soft piece of felt or india-rubber. This pad is suspended by means
of its uppermost rol, which is somewhat longer than the others and rests in a recess
formed at the upper edge of the box, being held by spiral springs against the said
helices.
The nipples are put against a plate covered with soft india rubber or the like and
suspended by two springs which are arranged to be displaced in the horizontal
direction so as to obtain the proper tension for pressing the milk from the nipples.
Below the box are provided two bent springs and a handle.
When the milking is to take place the left arm is passed between the aforesaid
bent springs and the handle seized. The apparatus is placed in such a position that
two nipples will be at the same time between the above-mentioned pad and plate
whereupon the crank is turned. The milk obtained passes through a pipe provided
in the bottom of the box and having attached to it an indiarubber pipe which
extends to the milk pail.
To facilitate the milking the apparatus may be suspended by hooks through the
medium of an elastic band passing over the back of the cow.

COMPLETE SPECIFICATION.
An Improved Apparatus for Facilitating the Milking of Cows.
WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
45 Southampton Buildings in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement:-
This invention relates to a milking apparatus which is applied to the nipples of

page_text: the cow and effects the milking by a pressure commencing at the upper part of the
nipples and gradually descending to their lower extremity so that the milking takes
place easily and conveniently.
In the accompanying drawing
Figure 1 represents the apparatus in the position in which the nipples are com-
pressed above so that the return of the milk into the udder is prevented.
Figure 2 shows the apparatus in the position in which the nipples begin to fill
again, and
Figure 3 shows the apparatus as seen from above before the milking commences.
The apparatus comprises a box a which is open at the top, and contains helices b
each of which is secured upon a separate rotary shaft . The rotation of the said
shafts is caused by means of the toothed wheels t.s a shaft and crank h. In the
rotary movement the helices exert a periodically recurring pressure upon a freely
suspended pade which is flexible in all its parts, so that the pressure begins above
and gradually descends to the lower end. This pressure first ceases above, is then
continued downwards and immediately afterwards ceases here also. During the
remaining part of the revolution of the helices they do not act upon the nipples, so
that these are freely suspended and have time to be filled again with milk.
Ր
The pad consists of brass rods which are connected with each other by rings and
covered on the side turned towards the nipples with a soft piece of felt or india-
rubber. This pad is suspended by means of its uppermost rod, which is somewhat
longer than the others and rests in a recess formed at the upper edge of the box a
being held by spiral springs p against the said helices.
The nipples are placed against a plate d covered with soft indiarubber or the like
and suspended by two springs e which are arranged to be displaced in a horizontal
direction whereby the tension can be regulated so as to obtain the proper motion,
for pressing the milk from the nipples. Below the box are provided two bent
springs and a handle f.
When the milking is to be commenced the left arm is passed between the bent
springs and the handle is firmly grasped.
The apparatus is placed in such a position that two nipples will be held at the
same time between the pad c and plate d whereupon the crank is turned.
The milk passes through a pipe provided in the bottom of the box a and having
attached to it an indiarubber pipe which extends to the milk pail.
To facilitate the milking, the apparatus may be suspended by hooks m through
the medium of an elastic band passing over the back of the cow.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
A milking apparatus in which the nipples are pressed by rotary helices against
a plate d, provided with a soft cover, in such a manner that the helices cannot come
in contact with the nipples, and that in the rotary movement of these helices the
pressure upon the nipples will descend and finally cease so as to preclude the return
of the milk into the udder and afford the nipples time to be filled again with milk.
