COMPLETE SPECIFICATION.
Improvements in Safety Devices for use in Milking Cows.
I, CHRISTOPHER COLUMBUS PALMER, of Bantam, in the County of Litchfield,
and State of Connecticut, United States of America, Blacksmith, 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, reference being had to the accompanying drawings and to letters of
reference marked thereon, which form a part of this Specification
Figure 1 of the drawings is a representation of the invention and is a perspective
view.
Figure 2 is a detail view of the fender board.
Figure 3 is a vertical section, and Figure 4 is a top view, of head part of stall.
This invention has relation to safety devices for use in milking cows; and it
consists in the novel construction and combination of parts, as hereinafter set
forth.
The object of the invention is to provide a frame-work of such construction as
will insure safety to the milker and prevent the cow from overturning the pail, and
at the same time to make this frame-work of such construction and to provide it
with such suitable gearing as will enable the operator to conveniently adjust the
device in any stall.
In the accompanying drawings A indicates the head part of the stall, and the
cow is shown with its head inclosed in the stanchions, one bar of which is fixed, and
the other bar a' is movable and extends through and a little above the top timber
of the head-frame, and which may be fastened or unfastened by means of the
latch in the end of which a rectangular notch is cut to partly surround the upper
end of the movable bar a¹.
C is the movable milking chair, and is of the following construction: Two broad
side pieces cc, with the cross piece d all fastened firmly together, form the frame
proper. The lower front portions of the pieces cc, are provided with slots e e for
the reception of the adjustable-fender board D. The fender-board is introduced in
the slot in either side and is pushed through in front of the cow's hind legs and
into the slot in the opposite side piece, and is provided with notches ff-whereby it
is sufficiently secured, and thus danger from the kicking of the animal is averted.
Near the base and on the outer face of each side piece c is a flange g, which serves
as a rest for the sliding foot-rail E, which foot-rail prevents the cow from stepping
back or kicking. Guides hh serve to keep this rail in normal position, allowing
only rectilinear horizontal motion.
On the inner face and near the base of each side piece c is pivoted a locking-
lever k, provided on its base with projecting pins, whereby the foot-rail E may
be secured in any desired position. Also on the inner face of each side piece c at
about the level of the floor of the stall, is fastened a guide-bar m, which projects
forward beyond the front edge of the side piece c and serves as a guide and rest for
n

page_text: the sliding shelf n, which in turn serves as a rest for the pail or receptacle for the
milk.
At
p
in one side piece is fastened one end of a rope provided with a hook at the
other end. The rope is of such length that it may be passed over the back of
the animal and caught or secured in an aperture or around the edge of the other
side piece.
The milking chair rests on rollers which permit it to move forward and backward
in each stall, and at the same time it is suspended from an overhead beam or other
suitable device by means of ropes passing through the eyes o o, whereby it may be
moved along the series of stalls.
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 what I
claim is :-
1. In a safety device for milking cows, the combination of the movable frame
consisting of two upright side pieces and the top cross piece, the removable fender
board held by the side pieces, the sliding and adjustable foot rail, the locking
levers k, pivoted to said side pieces and adapted to hold said foot rail in adjustment,
and the shelf or pail rest in front of and supported by said side pieces or arms
therein, substantially as specified.
2. The device for the purpose herein described, comprising the frame supported
on rollers and suspended from an over-head support, said frame having the fender-
board removably held in slots in the side pieces thereof, the adjustable and sliding
foot-rail, and the shelf or pail-rest supported by said side pieces or arms thereof,
together with a back strap or cord, substantially as specified.
