MILK-TESTER.

SPECIFICATION forming part of Letters Patent No. 478,099, dated July 5, 1892.

Application filed December 4,1891. Serial No. 413,965. (No model.)

To all whom it may concern.-

Be it'known that I, FRANK B. FARGO, of Lake Mills, in the county of Jefferson and State of Wisconsin, have invented a newand useful Improvement in Milk-Testers, of which the following is a description, reference being bad to the accompanyingdrawings, which are a part of this specification.

My invention relates to improvements in the class of milk-testers in which the milk is placed in tubes or bottles with small and preferably graduated necks, and frequently with a small supply of acid, and the tubes are then agitated by mechanism therefor, commonly warmed by hot water or other heatsupply, for the purpose of separating the butter or butter-oil from the caseine' and whey to ascertain the amounts and proportions of each in the milk.

The object of my present invention is to improve the apparatus for supporting and agitating the milk tubes or bottles.

In the drawings, Figurel is an elevation of a complete milk-tester in which my improved devices are embodied, the inclosing case being shown in central vertical section. Fig. 2 is a top plan view of the complete device, the case being removed, exposing the plan of its interior. Fig. 3 is a View of the under side of the supporting-table and of the mechanism attached thereto. Fig. 4 is a modified form of a disk for supporting the bottle-holding receptacles. Figs. 5 and 6 are perspective views of two forms ofbottle-holding receptacles.

A is atable of suitable form and size to support the other parts of the apparatus. A cylindrical case B rests on the table. This case is provided With-a water-tight bottom 0 at a little distance above the table, on which it rests on a suitable flange, forming an airchamber between the table and the bottom from which a smoke and gas flue D leads at one side of the case upwardly and discharges into the air. An apertureE through the table permits the heat and heated air from the lamp F to rise directly against the bottom 0 of the case, the smoke escaping through the flue D.

A disk G is fixed on theupper extremity of a revoluble arbor H, having its bearing in the table and in a stud or hanger I, projecting on the disk.

forminga water-tight tube K about the shaft H, so that the case may be supplied with water up nearly to the disk, if desired. The

I cover B of the case is removable, and the case is provided with a faucet J for drawing off the water. The shaft H is provided with. a pulley on which the belt L runs, which also runs on the larger pulley M, the arbor of which pulley is geared to a hand crank-shaft N, which shaft and the arbor of the pulley M are journaled. in suitable bearings therefor arranged on the table A. An idle belt-tightening pulley O is secured adjustably to the table and bears against and is adapted for tightening the belt L.

The disk G is provided with peripheral recesses G, in which the receptacles P are fitted loosely, so as to be readily removable therefrom, but so as to be held bythe walls of the recesses against lateral movement. These receptacles P are each provided with arms R,

having hooks thereon adapted to enter apertures therefor in the disk G, whereby the receptacles are suspended from and supported The lugs V,'projecting downwardly from the disk at the inner edges of the recesses G, receive the bearing of the receptacles and prevent their tilting inwardly when hung on the disks. These receptacles, as shown in Fig. 2, are each provided with three vertical compartments, each adapted to receive and hold therein a bottle S. These bottles are of the form in common use, being usually provided with the long graduated neck S, desirable in such milk-holding tubes or bottles. These receptacles P are detachable from the disk G and the bottles S are removable from the receptacles.

This apparatus is utilized as follows: A supply of water is put in the case B, preferably already heated, and itis kept warm during the making of the test by the burning lamp F. The milk to be tested is put in the several bottles S, which bottles are placed in the receptacles P, and the receptacles are secured to the disk G in the case, in the manner described. The case is then covered and the milk is agitated by revolving the disk by rotating the shaft N. When the process is completed, the milk-receptacles may be removed from the case and the water can be drawn off through the faucet J.

In the modified form of disk T (shown in Fig. 4) the peripheral recesses TT are sufli Y cientlylarge to receive thereinmodified forms of receptacles P, which have four compartments, the recesses T being each sufficiently long circumferentially to receive therein part of a receptacle, Fig. 5, having two bottles alongside each other. This disk also is provided with a circle of apertures U about but at a distance from its axis, which apertures are each adapted to receive therein. a single receptacle P" of the form shown in Fig. 6. This disk T is also provided with suitable apertures adjacent to each of the recesses 'I" and U for receiving therein the upright on the disk in the recesses in the periphery thereof, substantially as described.

2. In an apparatus of the class described for testing milk, a revoluble disk provided with peripheral recesses and with apertures at a distance from its axis other than the peripheral recesses, which apertures are adapted to receive therein removable bottle-holding receptacles suspended on the disk, substantially as described.

3. In an apparatus of the class described for testing milk, a revoluble disk provided with peripheral recesses and hook-receiving apertures, in combination with receptacles adapted to hold milk-test bottles formed to fit detachably in the peripheral recesses in the disks, arms projecting from the receptacles, having hooks adapted to en gagethe disks, and downwardly-projecting lugs on the disk, arranged to receive the bearing of the receptacles and prevent their tilting, substantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.

FRANK B. FARGO.
