WITNESEEE WM JAM/4 W ITEL STATES WILLIAM A. WILSON, OF CHELSEA, MASSACHUSETTS.
' IMPROVEMENT IN COW-MILKERS.
Specification forming part of Letters Patent No. 188,455, dated March 13, 1877; application filed I August 21, 1876.
To all whom it may concern:
Be it known that I, WILLIAM A. WILSON, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new andwhich serves to form a'vacuum in the chamber A, to which it is connected by an exhausttube, 0. D D D D are four tubes, made of hard rubber or of any non-corrosive metal. Each of these tubes has perforations near the upper end, and is connected, by flexible tubes H H H H to the can or vacuum-chamher A. To render these teat-tubes self-sustaining and adjustable, I attach to a standard, K, which is made fast to the top of the can, a
jointed arm, L L L arranged as shown, so that its upper extremity M may be placed at any desired height. At the point M I attach, by a swiveljoint, the horizontal cross-arms N N. At each extremity of the cross-arms N N I joint a forked arm, P P P P, said forks having elasticity sufficient to allow them to be sprung onto the teat-tubes and thus hold them.
By this arrangement the teat-tubes D D D" D may be set'and held in any desired position.
Having now described the construction and operation of my invention, what I claim is as follows:
forth.
WILLIAM A. WILSON;
Witnesses:
WILLIAM EDSON, N ATHL. EVANS;
