CENTRIFUGAL. MILK-TESTER.
SPEGIFICATION forming part of Letters Patent No. 742,801, dated October 27, 1903. Application filed July 3, 1903. Serial No. 164,124. (No model.)
To all whom, it may concern;
Be it known that 1, WILLIAM E. PENN, of Lakemills, in the county of Jefferson and State of Wisconsin, have invented a certain new, useful, and Improved Centrifugal Milk- Tester, of which the following is a specification.
My invention relates to centrifugal milktesters for conducting the well-known Bab- [O cock test, by which the percentage of fat contained in milk or cream is determined The invention has special reference to centrifugal milk-testers of that class which are operated manually; and the object of myinvention is to provide a small compact inclosed tester that shall resemble and possess the good qualities of the larger steam driven testers.
Another object of my invention is to provide acentrifugal tester of reduced diameter, and still another object is to provide a simple, compact, and thoroughly-efficient driving mechanism for the test-bottlecarrier.
My invention consists generally in a cen- 2 5 trifugal milk tester comprising a vertical shaft, in combination with a bottle-carrier mounted thereon and provided with a rim having a series of pendants wherein the testbottles are carried, the arrangement being such that the bottles assume a tangential position with relation to the shaft when the carrier is rotated; and, further, my invention consists in a centrifugal milk-tester comprising the aforesaid combination with an inclos- 3; ing casing, wherein said shaft is arranged; and my invention also consists in and includes a driving mechanism connected with the upper end of the shaft upon the top of said casing, all as hereinafter described, and
particularly pointed out in the claims.
The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a plan View of a centrifugal milk-tester embodying my invention. Fig. 2 is a vertical section thereof substantially on the line X X of Fig. 1. Fig. 3 is a horizontal section on the line Y Y of Fig. 2. Fig.
5o 4;is a similar view showing the pendants as they appear during the rotation of the bot tie-carrier. Fig. 5 is an end view of the operating-crank. Fig. 6 is a detailed vertical section substantially on the line Z Z of Fig.
1, and Fig. 7 is a horizontal section on the line V V of Fig. 6.
As shown in the drawings, the bottle-carrier of my machine is inclosed in a neat compact casing, which comprises the upper and lower'halves 2 and 3, having a fiangedjoint 4. 6c The lower part is provided with suitable legs 3 and the upper part has an opening which is closed by a door 5. This door is hinged on the lugs 2 of the lower part and when opened permits access to the bottle-carrier that is ar- 6 5 ranged within the casing.
6 represents the tester-shaft. This is seated in the step-bearing 7, provided in the bottom portion of the casing. Said step-bearing is preferably in the form of a boss, which pro- 7c jects above the bottom of the casing, making said bottom a receptacle for milk and water that may be spilled therein and protecting the bearing of the shaft. The upper end of the shaft passes through the central opening 8 in the top of the casing and is held in the detachable bearing 9. This bearing is a part .of the block 10, which rests upon a planed face or shoulder 11, provided on the top of the casing. (See Figs. 5 and 6.) The block is secured by two screws 12 and 13, which pass through the same into the shoulder 11. The Opening for the screw 12 may be such as to fit the samesnugly; but the Opening for the Screw 13 is preferably larger than the shank of said screw or may be a slot, which will permit the inner end of the block to be moved toward or away from the shaft 6. The upper end of the shaft 6 is provided with aworm-screw 17, and this is engaged by the 0 large worm-gear 18, provided on the inner end of the shaft 16. The adjustability of the block 10 permits the shaft and worm-gear to be brought into exact positions for operation with minimum friction. It will be observed that the bearing 9 is a part of the block 10, but is considerably below the center of the gear 18, and any movement of the block will tend to throw the worm away either from or toward the worm-gear. The opening 8 is of I00 sufficient size to permit this movement of the shaft 6, and the same may be alined with ease. Vertical movement of the shaft is prevented by a collar 6, provided thereon beneath the top of the casing. The block is also provided with a bearing 19 on its outer end, overhanging the side of the casing. In this bearing is journaled the stud-shaft 20 of the crank 21, and the connection between the crankand the shaft 16 is made by means of the large gear 22 and the pinion 23 upon the crank and the shaft 16, respectively. By means of this mechanism taken as a whole the shaft 6 of the tester may be rotated at an extremely high speed.
The bottle-carrier referred to comprises the rim 24, the radial arms 25, and the hub 26, said parts preferably being integral and said hub being secured to the shaft 6 by a clutchpin 27. The rim 24 formsa preferablyirregular polygon and has for its essential portions the straight sections 24, which lie substantially at right angles to the radial arms '25. At the end of each such section 24 is a retaining or guard lug 28, with a slot between the same and the portion 24. The bottle-pendants or twin cups 29 swing from the rim 24, the same having loops 30, which straddle the straight portions 24 of the rim, and when the bottle-car- .rier is rotated at a high speed these pendants swing outward and assume positions in a horizontal plane, as illustrated in Fig. 4. It will be noted that the pendants do not occupy radial positions and that their tendencyto'assume such positions is counteracted by the lugs 28. The bottles which are placed in the pendants have long necks, and when the pendantsrise to a horizontal position said necks are thrown downward and approach the sides of the shaft 6 at tangents thereto. The purpose of this construction and arrangement is to secure suflicient space for the bottle-necks between the rim and the shaft and at the same time reduce the diameter of the bottle-carrier to such an extent as to make a material saving in the cost of the machines and in the space occupied thereby as compared with the ordinary circular bottle-carriers.
It is obvious that numerous modifications of my invention will readily suggest themselves to one skilled in the art, and I do not confine my invention to the specific constructions herein shown and described.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 7 1. A centrifugal milk-tester, comprising a suitable frame or casing, in combination with a vertical shaft, having bearings at its upper and lower ends, in said frame, a bottle-carrier on said shaft within said frame, and a manual shaft-driving mechanism, provided on the upper part of said frame, substantially as described.
