Figure 1 is a front view of the machine,
Figure 2 a section on the line I--I of Figure 1, and
Figure 3 a plan.
In the frame a are supported parallel to each other the two milking cams bb.
On one side of the frame a the crank c is arranged upon the prolonged axis of one
cam b, while on the other side of the frame the axes of the two cams carry the cord
pulleys d d. These pulleys are connected by a crossed driving cord f so that the
cams b b are turned in opposite directions when the crank c is actuated.
Between the two cams bb are arranged two bent plates 9 g designed to support
the nipples laterally. These plates are pivoted by means of the supports to the
cross piece i. By the springs k k likewise fixed to these cross-pieces the supporting
The sides of the
plates 99 are kept apart and pressed towards the cams bb.
supporting plates 9 g, which are turned towards the cams bb, are provided with a
cover of indiarubber or other elastic material, as shown in Figure 2. Immediately

in front of the cams bb elastic cloths // are suspended from the rods m m.
milking machine is fixed by means of the rods n n above the milk receptacle o.
For this purpose the latter has say on both sides clamps p p into which the rods nn
are inserted. For enabling the milking machine to be fixed at different heights
according to the size of the cow to be milked, we fix to the clamps p the plate
springs u the pins t of which engage with holes in the rods n, as shown in Figure 1.
In lieu of these spring pins we may also use screws, inserting pins or other means
serving the same purpose. By means of the transverse bolt arranged on the
frame a the machine can be easily handled and transported.
In use the milking machine is so placed beneath the animal to be milked that the
nipples of the udder are between the cams b b and the elastic supporting plates g g,
as shown in Figure 2. When the crank c is then actuated so that the cams turn in
the direction of the arrows indicated in Figure 2 the edges of the cams move from
above along the nipples downwards; under these conditions the nipples are pressed
against the elastic supporting plates 9 g, while the milk is forced out and is taken
up by the milk receptacle o placed beneath. Before the following edges of the
cams begin to act in the further milking process the nipples have become refilled
with milk which is again forced out, and so on. The elastic cloths 1 suspended in
front of the cams b b and the elastic cover of the supporting plates 3 g prevent the
immediate contact of the nipples with the hard cams and supporting plates so that
no injuries will occur.
The milking by this machine takes place in a similar manner as by hand.
We may vary the construction of the milking cams and supporting plates; for
instance in lieu of the double cams use may be made of single cams, or three cams
may be provided on each axis. The capacity of such a machine is very great ;
special skill is not needed for operating it. The details of construction may of
course also be varied, the essential feature of our said invention being the mode of
action of the milking plates.

page_text: 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 :-
First. A milking machine characterized by rotary milking cams 6 which in their
turning movement press the nipples of the animal to be milked against elastic
supporting plates g and move from above along the nipples downwards in order to
force out the milk contained therein.
Second. A constructional form of the milking machine characterized in the first
claim, in which the lateral elastic support is formed by plates g bent inwards and
provided with an elastic cover, which plates are pressed by springs k towards the
milking cams b, and in which protecting cloths of elastic material are arranged
interiorly in front of the cams b.
