JOHN D. WINTERS, OF DAVISVILLE, CALIFORNIA.

WASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,364, dated December 19, 1882. Application filed June 3, 1882. (No model.)

To all whom 21 may concern:

Be it known that I, JOHN I). WINTERS, of Davisville, county of Yolo, State of California, have invented an Improved \Vashing- Machine and Churn; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in washing-machines, which is also applicable to churns; and it consists in certain details of construction and arrangement, as hereinatter fully described, and specifically pointed out in the claim. \Vit'hin the bodyare transverse bars or corrugations, and wooden balls roll from end to end as the liodyis rocked to ta.- cilitate the work. Beneath the body is a shelf, upon which a lamp or heater may be supported to regulate the temperature in churning, all of which will be more lully explained by reference to the accompanying drawings, in which Figure 1 is a perspective view of my apparatus. Fig. 2 is a longitudinal vertical section. Fig. 3 is a detail.

A is the body of my machine, the sides be-. ingelongated,with rounded ends, and united by wooden staves or metal plates,so as to inclose the vessel and give it the desired width. In the top of this vessel is a cover, B, fitting into a corresponding opening. This cover has its lower surface corrugated, as shown. btrips or corrugations U extend across the interior of the chamber, and a number of balls, D, are placed therein, so that when the chamber is rocked the balls and the contents will be carried from end to end over the corrugations. The body or chamber A has bars E, secured to each edge, and pins F are fixed in the center of each bar, projecting downward into the convex supports G, upon which they rest, so that when rocked from end to end by means the handle H the body will not slide off the supporting convex bases. At one side of this base is a projection, into which the lower end of the spring I is fixed. A lug, J, is fixed to the body A near the top and directly above the point where the spring is fixed. A slot is made in this lug, through which the upper end of the spring passes, and when the body A is rocked to one side or the other the spring will be bent to that side, and its tension will return the body to the central position again.

By this construction the center of motion of the chamber A, when it is in its normal position, is verticallyin line with the center of the arched or convex surface upon which the chamber oscillates, and its center of gravity is also close to the point about which it moves. When the chamber is oscillated the center of gravity moves in a small arc to each side of the center of motion, butis not carried to any great distance from it, and the chamberis thus easily returned to its central position, notwithstanding the rush of the contents to the depressed end. In this respect it is superior to those rockers in which the chamber is oscillated in a concave support, and has its center of gravity at a considerable height above the center of motion. Such a machine is difficult to operate on account of the transferring of so great a weight alternately to one side and the other and the power required to return it again.

Beneath the bodyAis fixed a shelf, K, upon which a lamp or heater may be supported when the device is used as a churn, and the temperature of the cream thus regulated at will.

I am aware that boxes having convex bottoms have been arranged to oscillate upon concave supports, and I do not claim such a device.

I am aware that two convex surfaces have been connected with a rubber spring so as to admit of a rocking motion; but I do not claim Such as my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a washing-machine, the elongated body A, having strips 0 and rounded ends, in combination with asupporting-base, G, haviugconvex bearing-surfaces, vertical straight spring I, rigidly secured to the base and projecting through bracket; J on the body, and pins F, projecting from the body into openings in the base, all constructed, arranged, and operated as set forth.

In witness whereof I hereunto set my hand.
