PNEUMATlC MILKER.

SPECIFICATION forming part of Letters Patent No. 439,552, dated October 28, 1890.

Application filed January 22, 1890. Serial No- 387,727. No model-I T0 all whom it may emwern:

Be it known that I, JULIUS 'l. POMEROY, of Edger-ton, in the county of Rock and State of Wisconsin, have invented a new and Improved Pneumatic Milker, of which the followingis a full, clear, and exact description. y invention relates to improvements in milking-machines; andtheobjechof myiuvention is to provide a simple and efficient device that may be easily connected with the teats and udder of a cow, that will quickly transfer the milk from the udder of the cow to the pail of the machine, and that will prevent the milk from being contaminated by foreign and offensive matter.

The invention will be hereinafter fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, iii-which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section of the machine; Fig. 2, a detail view of the end of one of the milking-tubes that is inserted in a teat; Fig. 3, a plan view of the machine with the pumptube in section on the line .131: of Fig. 1, and Fig. l a detail view showing the manner of attaching the top cover to the pail.

The pail A is provided with a suitable handle B, by which it maybe carried about, with a spout C, through which the milk is poured, and with a removable cover 1), to which is attaehedthe air-pump tube E. The pail A also provided with a shoulder it around the opening in the top upon which the cover I) rests and with two upwardly and forwardly extending lugs I, which are attached to the top of the pail upon opposite sides of the opening in the top, and which extend above the cover I). The lugs b are each provided with a thumb-screw (I, which extends downwardiythrough the lugs and engages the laterally-extending ears 6 of the cover D and holds the cover tightly upon the pail. The cover I) is provided upon opposite sides with an ear :3, which may be turned beneath the thumb-screws (I of the lugs h when the cover is to be fastened in place, and with an annular shoulder f, which extends around its lower edge and tits closely upon the shoulder a of the pail. \Vhen the cover is to be fastened to the pail, a packing-washer g, of rubber or other suitable material, is placed upon the shoulder a of the pail, and the cover D placed upon the pail so that the shoulderf will rest upon the packing-washer. The cover is then turned till the ears 6 are beneath the thumbscrews 1?, when the thumb-screws are turned down, and, impinging upon the cars, they will fasten the cover securely upon the pail, and the packingwasher g will insure an air-tight joint.

The tube E opens through the cover D into the pail A, at which point it is provided with an ordinary check-valve 72, which opens from the pail into the tube. Above the valve 71 and movable vertically in the tube E, is a piston F, which is provided with an ordinary suction-valve '1', and which is pivoted by the cross-barj to the piston-rod II, which ext-ends upwardly through the removable cap E at the top of the tube, and is provir. .d with a suitable handle J, by means of which it is operated. This makes a very simple airpump, and by grasping thehandle J and moving the piston up and down in the tube E the air may be pumped from the pail. I do not confine myself to the use of this pump, however, as any suitable pump may be employed. 5 -,Opening from the upper part of the pail and upon one side thereof are four proj ecting metal tubes is, upon which are fitted four rubber tubes is, whichare to connect the pail Awith the udder of acow. of a convenient length, are provided at the free ends with a metal. nipple l, and are also provided with a section of glass tube on near the pail, which enables the operator to see if the milk is flowing properly through the tubes. The nipple is provided with a spreader l', which extends outwardly from the end thereof, and which consists of two fine wires having their ends attached to the tube, and having their outer extremities bent to form a dull point. The wires composing the spreader l are placed at right angles to each other and are so bent that the formed spreader will have an oblong shape, and will terminate in a dull point.

The machine is operated as follows: The pail A is placed upon the floor or ground at The rubber tubes 7.; are

2 eeeese one side of the cow and the nipples Z and spreaders l inserted in the cowsteat. The nipples will fit closely in the vent of the teat and the spreader will extend upwardly into the milk-receptacles and hold the tissues apart so that the milk will flow through the nipples and tube to the pail. When the tubes are connected with the cowsteats the air-pump is worked, thus creating avacuum in thepeil, and the suction from the pail, combined with the action of the spreeders, Will cause the milk to how quickly and freely to the pail till the cow is milked dry. It will thus be seen that the cow will be quickly and easily milked, and as the pail is .tightly covered the milk will be entirely I free from contamination. Vhen the pail is to be emptied, the thumbscrews d are loosened and thecover D re moved.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent-,is- 1 V 1. In a miike'r, a. tube Z, provided with aspreader Z, consisting of two wires looped and crossed at their outer ends and secured at their inner or free ends to the tube, the wires being disconnected attheirtpoint of crossing,

substentiallyas set forth.

2. The combination, with a milk-receptacle provided with an stir-exhausting mechanism, of tubes leading from the vessel and provided attheirouter ends with spreedeisconsistiug of looped and crossed wires disconnected at their points of crossing and connected at their inner ends with the said tubes, substantially 5 as set forth.
