iM'PRovEMENT IN cow-MILKERS.

.Specification forming part of Letters Patent No. 154,811, dated September 8, 1874 application filed July 24,1874.

To all whom it may concern:

Be it known that we, JOHN MARTIN STAN- LEY and HENRY JAMEs, of Sheffield, York county, England, have invented certain Improvements in Appliances for Milking Cows, of which the following is a speciiication:

Our present invention has for its object im-.,

provements in the present appliance for milking cows, which will save time and labor, and secure a more cleanly process of milking.

In order that our said invention maybe more clearly and more fully understood, and l be .more readily performed, we now proceed to explain the same, with the aid of the accompanying drawing, which forms part of this elevation ofa similar apparatus fitted in the neck of a milkcan. Fig. 3 is a full-size elevation of a small iiexible tube, and its metallic tube for insertion in the cows teat, which metallic tube is hereinafter called the insertion-tube,77 also showing our improved elastic bands and loop for holding the saidinsertiontube in place during the milking process. Fig. 4 is a full-size view of the lower end of the said small flexible tube, showing a short metallic tube or lining tted therein.

lIn carrying our present invention into practice, we propose to use flexible tubes a, with metallic insertion-tubes b. The four ilexible tubes a are inserted and secured in one end of a larger tube, having an internal-cavity or common channel large enough to receive therein, and convey to the milk-pail cor can d, (hereinaftercalled receivingvessels,) the four streams of milk from the four teats of the cow through the four ilexible tubes a. This Y common. channel may be made of any suitable material, either flexible or rigid, or partly of each, and be arranged to slide in the neck h2 h3 of the receiving-vessel. The lower part f of the said common channel (shown in Fig.1) is formed of metal, and in which part f the Asliding the lower or upper part g, made of vulcanized caoutchouc, slides. The common channel f (shown in Fig. 2) is wholly of vulcanized caoutchouc in one tube, the lower end of which slides in the neck h3 of the milk-can d, and is provided with a free elastic ring, i, fitting sufficiently tight to support the tube ff, and prevent its sliding down in the neck of the receiving-vesselfbelow the point at which it is fixed or placed.

To prevent dirt or other impurities from passing into the receiving-vessels during the process of milking, we iit such vessels with a top, h h1, or a movable lid or cover, by preference in the form of a dome, which top or cover has, in or near its center, a neck, socket, or nozzle, h2 h3, in which the lower end of the common channel slides; or the top or cover may be tted with two necks, sockets, or nozzles, to receive a common channel from two cows at the same time, so thatthe milk passes from the cow or cows to the receiving-vessel without exposure, and consequently free from admixture with any foreign matter whatever. The common channel (shown at f g, Fig. l) is lengthened or shortened, at pleasure, by metallic tube f in the neck h1 of the top or cover h of the receiving-vessel, and fixing such tube f at the required distance or length by a set-screw, fi, fitted in or to the neck h of such top or In order to prevent the insertion-tubes b from sliding or dropping out of the teats of the'cow by any motion of the latter, or otherwise, during the process of milking, we secure the said insertion-tubes in or to the teats by means of elastic bands or cords j, one end of which is attached to the root or lower part Y of such insertion-tubes, and having attached to their upper parts or ends an elastic loop or circular band or cord, 7o, of a suitable size-and strength to grasp the teat with just sufcient pressure to hold the insertion-tubes bin place. Our improved apparatus is self-acting after ybeing attached to the cow, and the milking process occupies less time than usual, especially when two cows are milked into the same receiving-vessel at the same time.

Having thus fully described the nature of our said invention, and the method of performing the saine, We wish it to be understood or cords, substantially as herein described and that we do not claim the flexible tubes a, nor shown.

the insertion-tubes b, per so; but JOHN MARTIN STANLEY.

We claim as our invention, and desire to se- HENRY J AMES. eure by Letters Patent- Vitnesses:
