PERLEY L. KIMBALL, OF BELLOl/VS FALLS, VERMONT, ASSIGNOR TO THE VERMONT FARM MACHINE COMPANY, OF SAME PLACE.

BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 478,113, dated July 5, 1892.

Application filed May 8, 1890. Serial No, 850,983. (No model-l To all whom it may concern.-

Be it known that I, PERLEY L. KIMBALL, of Bellows Falls, in the county of Windham and State of Vermont, have invented certain new and useful Improvements in Power Butter- Workers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figuresof reference marked thereonjwhich form a part of this specification.

My invention relates to the class of machines known as butter-Workers, and more particularly to special means whereby such machines may be driven by-power instead of by hand and to other devices incident thereto.

In the accompanying drawings, Figure 1 illustrates in plan view, and Fig. 2 in elevation, with a part of one side of the tray broken away, a butter-worker embodying my invention; and Figs. 3, 4, and 5, details.

A is a stationary tray of a well-known seg mental form, but preferably having a steeper inclination than usual, and it is supported on .suitable legs a a and has slanting sides I) b;

O, a roller having a series of fiutings, preferably dull and shallow, and whose shaft or support P is connected at its inner end to a small gear D, which is free to run on a rack E, curved in the arc of a circle and secured at the inner truncated edge of the tray. An ad ditional post or leg 0. on an extension of the tray-frame serves to assist in supporting the driving mechanism, hereinafter described.

The outer end of. the roller-shaft has its bearing in a carriage or frame 1, having rollers adapted to be guided by and to run on a track at the larger end of the tray and presently to be described.

I will now proceed to describe a power mechanism and its connection with or attachment to my improved butter-worker and serving to illustrate how I can apply the power at the smaller end of the segmental tray and yet impart to the pressure-rolleratransverse motion to and fro across the tray, causing both its smaller and its larger ends each to travel in its proper path.

By the phrase power mechanism as used in this specification and claims I wish to be understood as meaning mechanism adapted to be driven by steam or other power instead of by hand for operating my improved butterworker.

F represents a main or prime motor-shaft of the machine, driven by any suitable power, such as water, steam, electricity, &c.; G, a pulley on the same, adapted for a driving-belt, this shaft and its small gearH being supported in suitable hearings in apulley frame or supports f, (see Fig. 4,) which are upheld by the upright I. This upright or post I has permanently secured to it one end of a horizontal piece or beam 2' and the other end of this piece 2' centers or pivots on a vertical shaft 10 of wheel K, as hereinafter described, this shaft 10 being supported on a cross-beam m, projecting horizontally from the post or leg 0. of the tray. This pivoting of the uprightIand its attached parts on the shaft k as a center allows of th eir being shifted either to the right or to the left on such center relatively to the position 'of the tray and its supports or of similarly shifting the tray relatively to the supports I and its attached parts.

The gear II engages with a compound wheel or gear K, which has acontinuous circle of teeth on its underside and less than a semicircle of teethl on its upper side, the teeth is gearing with and being driven by the gear H on the shaft F. The wheel K is mounted on a vertical shaft supported in the crossbeam :20, such shaft having a nut 70 on its lower end beneath the beam 00.

M is a reversing-shaft supported in suitable bearings in the leg (0 and also in the leg or support a of the tray and providedwith two pinions N N, which are so placed thereon that during the continuous revolution in one direction on the compound wheel K they shall alternately engage with and be disengaged from the teeth Z. In this way the shaft N is driven first in one and then in the other direction, and this reversing or reciprocating rotary motion,assisted by a pivoted arm R, presently to be described, gives to the shaft which carries the roller a positive traverse motion by means of the following intermediate mechanism. The inner end of shaft M has a universal, articulate, or ball-joint connection with a link 0, whose other end has also a similar connection with the shaft or spindle P of roller 0, this spindle carrying the small gear D, which engages with the arched rack E, as already stated. The roller is preferably secured to its shaft; but it will be evident that, the shaft being given positive traverse movements, the roller may, if desired, be placed loosely thereon. The spindle P at its inner end is supported in a sleeve 1), which is held in a bracket 12 that is secured to the vibratory bar R, presently to be described. At the outer or larger end of the roller 0 is the frame or carriage 1, in which it has its bearings and which has a set of upper and lower frictionrollers q q, running, respectively, on the upper and lower faces of the curved track 2. Beneath the tray is a bar or arm R, pivoted at the rear of the tray at r, and its front end is connected to this traveling frame 1 above named. This lever bar be ing, as above stated, pivoted at one end and positively vibrated by the to-and-fro movement or traverse of the bracket in which is held the sleeve 1), it will be evident that the carriage 1, which is attached to this bar,

must travel coincidently with it and the outer end of the roller-shaft, being supported in this carriage, must traverse coi ncidently and positively with its inner end and without any lagging or dragging behind either of the shaft or the roller which it carries, and this avoids any undue strain on the rack or on the gear D.

The outer end of the axle 3 of roller 0 pro jects through a vertical slot 4 in the carriage frame 1, and also through .a horizontal slot 5 in a lever 6, pivoted on one side of this frame and provided with a sliding catch 7, adapted to engage with any one of the teeth 0' on frame 1. This slide hasa projection S, by means of 9 is a which it may be pulled by the finger. reacting spring. The slot 5 at its open end curves downward, as shown. Upon pulling on the finger-spur 8 of slide 7 to release it from a tooth with which it may be in engagement the roller-shaft may with one hand be instantly raised or lowered by the lever and adjusted to any desired height, dependent upon the amount of butter placed in the tray and the amount of pressure required. Power being applied to the main shaft, its pinion-gear I-I causes the revolution of the large wheel K, and as its teeth Z 011 its upper side come into engagement with the pinion N nearest the table or tray it causes the gear D to revolve through the agency of the shaft M and link 0, and this gear D as it revolves travels to and fro along the rack E, causing the to-andfro traverse of the roller-shaft P, the shafts M and P, with their universal joints, constituting one continuous flexible shaft and allowing it to accommodate itself to the different inclinations of the roll and its spindle when the machine is working butter.

In working the apparatus when the plain or cogless portion Z of gear K reaches either of the gears N N the roller-spindle stops at the end of its traverse and the cogs lot this gear at once engage with the other one of these gears N N, and the roller-spindle, then turned in the reverse direction, causing the roll to travel back across the table, and these traverse motions of the roll are repeated as long as the gear revolves, the roll traveling to and fro across the table with each revolution of the gear K. It will now be seen that the tray or table or the pulley-frame may be turned around on the shaft K as a center and placed, as may be convenient, at any angle relatively each to the other, and that the table may be at any angle relatively to the overhead shafting without the need of any twisted or angle belt from such shafting to the pulley G, andtherefore the pulley-frame can be placed in any position to suit the location or the arrangement of a room or at any angle, so long as it does not come in contact with the legs or posts a a and that the table, being triangular, may be placed in the corner of a room outof the way and still be driven by my power mechanism. The pulleys and their shaft and gear 11 may be placed on the left side of the worker 1nstead of on the right side, as shown in the drawings, as may be most convenient.

It will be observed that the roller-spindle gets its revolution on its axis from shaft M, and that its transverse motion is derived from the rack and gear, and that the removal or omission of such gear or rack and gear would not affect the revolutions of the spindle, but would prevent the traverse across the table.

The worker is simple in construction and has but little to get out of repair or wear out.
