SPECIFICATION forming part of Letters Patent No. 442,201, dated December 9, 1890.

Application filed January 27, 1890. $erial No. 838,235. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE ll. POUNDER, of Fort Atkinson, in the county of Jefferson and State of lVisconsin, have invented new and useful Improvements in Butter-\Vorkers; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

In the drawings, Figure 1 is a top plan view of my complete device. Fig. 2 is a side elevation of the same device, parts being broken away to show the construction more fully. Fig. 3 is an end view of the frame. Fig. i is a central vertical section of a central portion of the rotating table and devices connected therewith. Fig. 5 is a side elevation in detail of the device for raising and lowering the corrugated rollers. Fig. 6 is a modified form of the same portion of the device shown in Fig. i.

A is the frame supporting the operative parts of the butter-worker. A circular table B, which is depressed or dished centrally, is supported and rotates horizontally on bearing-wheels O C, journaled in blocks on the frame. These wheels C G bear against a circular track 1), secured to the under side of the table 15, the periphery of which track 1) forms a crown toothed wheel or rack E, which meshes with the toothed wheel F on shaft G, by the rotation of which the table is revolved. The shaft Ghas its bearings in the frame, and is provided with a beveled pinion G, which meshes with a beveled pinion on the driving-shaft ll, which is provided with fast and loose pulleys I and I, for carrying the power-transmittin g belt.

The top surface of the table ll inclines downwardly inwardly from the periphery toward the center, and at the center the table is provided with a shallow cup-like depression K, from thebottom of which at the center of the table a vertically down wardly-leading d not L is providethth ro ugh which buttermilk is discharged from the surface of the table. This d not L is preferably constructed in or lined by awooden tube M, which is surrounded and reenforced by a metal bushing N, and the duct is continued downwardly through the frame A in the manner shown in Fig. 6, or in an equivalent manner, as shown in Fig. 4.

Above the table B and at one side thereof are two frusto-conical corrugated rollers O O, which are located at a distance from each other and at a little distance above, but so that their under surfaces, respectively, are parallel with the adjacent surface of the table 15. These rollers extend from the periphery of the table 13 to or near to the edge of the depression K. These rollers O O are each fixed on a spindle O, which has its bearings in an independent frame P, supported adj ustably on the frame A, entirely at one side of the table B. The frames P P are each provided with a face which his against an upright part of the frame A, and is secured thereto adjustably vertically by means of a bolt R, inserted in the frame A and passing through a slot S therefor in the frame P. The frame P alongside the slot S is provided with a toothed rack T, and a block T on the bolt R, underneath the nut R thereon, is provided with corresponding teeth which engage the rack T, whereby the frame P may be socurely held on the frame A at the point to which it is adjusted vertically. The spindles 0' O are each provided with a fixed cogwheel U, which mesh with the cog-wheel U, fast 011 the driving-shaft ll. The faces of the teeth on the cog-wheels U U are slightly curved laterally to provide for gearing properly with the wheel U while located at an angle thereto.

The end legs V V of the frame A are secured rigidly together and are secured rigidly to the head-block XV, which head-block is pivoted to the frame A by means ofthe bolt and is further secured to the frame by the bolt \V. These legs when thus secured to the frame A by the bolts V and V, are rigid thereon in an upright position, but the bolt \V being removed, the legs are then secured to the frame A only by the pivotal bolt V, on which they may be swung underneath the horizontal portion of the frame in the manner indicated in dotted lines in Fig. 2, whereby the frame is put in convenient condition for moving it about, or, when desired, for packing it for transportation.

It will be understood that by reason of the construction hereinbefore described the frusto-conical rollers O 0 have no direct connection with the table B, nor is there any part of the frame that supports the rollers that passes through the table; but in some cases where great strain is put on the machine by heavy Work it is better to connect the frames P P at their rear ends by a removable extension-rod y. This rod y is Very conveniently formed in two parts, the outer ends of the rods being turned by screw-thread into the frames P P, the inner adjoining ends of the two parts being connected together by acoupling-nut having right and left handed screwthreads for receiving the ends of the two parts of the rod therein, the nut being thus adapted for drawing the two parts together or forcing them apart, as desired.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a butter-worker having a horizontally-revolving table, the combination,with two frusto-conical rollers fixed on revolving spindles diverging outwardly above and at one side of the table, and independent verticallyadjustable framesin which the spindles have elongated bearings, the spindles being provided with cog-wheels which mesh at an obtuse angle with an interposed cog-wheel on a driving-shaft, of an extension-rod connecting the outer ends of the spindle-supporting frames, said rod being formed in two parts, joined by an adjusting coupling-nut having right and left hand screw-threads, substan- 3 tially as described.

2. In a butter-Worker having a revolving table and frusto-conical rollers located and rotating parallel with and at an adjustable i distance above the table, the combination, with the frame of the machine, of spindlesupporting frames in which the spindles of the corrugated rollers have elongated bearings, which spindle-supporting frames are provided with vertical slots through parts fitted movably 011 the frame of the machine, toothed racks on the spindle-supporting frames alongside the vertical slots, and bolts passing through the frame and through the vertical slots, which bolts are provided With nuts turning thereon and with toothed blocks adapted to engage the racks on the adjustable frames, substantially as and for the purpose set forth. 1

In testimony whereof I affix my signature in 5 5 presence of two Witnesses.
