WASHING- MACHINE.

SPECIFICATION forming part'of Letters Patent No. 688,593, dated December 10, 1901. Application filed December 24, 1900. Serial No. 40,910. (No model.)

To aZZ whom it may concern.-

Be it known that LGEORGE CHAMBERLAIN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Washing-Machine, of which the following is a specification.

This invention relates to washing-machines; and the object is to provide an improved construction of washing-machine by the use of which the clothes may be quickly and effectively cleansed.

ith the above object in view the invention hereinafter fully described, particularly pointed out in the claim, and clearly illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of a washing-machine constructed in accordance with my invention; Fig. 2, a vertical sectional View of the same; Fig. 3, a bottom plan view, and Fig. 4. is a detail perspective view of the L-shaped guide-bracket.

Referring now more particularly to the accompanying drawings, A designates a rectangular frame supported at three of its corners by legs B, braced by bars 0, and having at its other corner a vertical standard D, forming a leg E for that corner of the frame and extending a considerable distance thereabove.

A circular base F of a tub or other receptacle is centrally pivoted to a cross-bar G of the frame and is adapted to rotate thereon, the same engaging friction-rollers H, carried by the frame and disposed at different points thereon. Mounted at its inner end in a bearing-block I, secured to the under side of crossbar G of the frame, is a shaft J, having its opposite end mounted in standard D and projecting therethrough. This shaft has thereon a friction-disk K, which engages the unrotation of said base, which has positioned thereon a circular flange which, together with the base, forms a tub L, as shown. Said friction-disk K may be moved back and forth upon shaft J, so as to vary thespeed at which the tub L is rotated, the disk being retained in its adjustment by frictional contact with the shaft. The projecting end of shaft J carries a sprocket-wheel M, around which a chain N passes, said chain passing also around a sprocket O on a driving-shaft P, mounted at one end in the standard D and at its outer end in a bracket Q.

The driving-shaft is provided with a crank- I handle R and a driving-wheel S,ineshing with a gear T, carried by shaft U, positioned above said drivingwvheel, and mounted at its outer end in bracket Q and supported at its inner end by standard D, through which it projects, and on its projecting end. provided with a wheel V, having a crank pin \V. The bracket Q is formed of a metal strap sccured to the standard D and separated there from to support the ends of the shafts before mentioned. This strap is bent to extend over the upper end of said standard and beyond the opposite face thereof, where it is bent downwardly to form an arm X, having its lower end bent at right angles and perforated to form a guide Y for a reciprocable rod, to which the pounder is attached. This is composed of two sections, one of said sections Z being tubular to receive the other section Z, which is adjustable therein and retained in its relative adjustment by set-screw a.

An L-shaped bracket 1) is secured to the standard, the projecting arm thereof being perforated to form the lower guide for said reciprocable rod, while the vertical portion thereof is slotted to form a guide 0 for the inner end of an arm d, the outer end of which is secured to the rod of the pounder. A connecting-rod e is pi votally connected at one end with the crank-pin W and at its opposite end to the arm (1, so that said pounder-rod is reciprocated as wheel S is rotated through the medium of the driving-wheel.

The lower end of section Z of the pounderrod is secured to a plate f, which is substantially triangular in outline, and secured to and depending from the under side of this plate are coiled springs g, the convolutions of said springs being gradually smaller, be ginning at their upper ends,so that the springs taper from top to bottom, as illustrated.

Extending upwardly from the frame is an upright h, and connecting this upright with the standard D is a cross-piece 11, to which the wringer may be attached.

The operation of the washer will be apparcut, the clothes being washed by the action of the plate carrying the springs as the same is reeiproeated,the water being forced through the clothes thereby.

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

In a Washing-machine, a frame, a receptacle rotative on said frame, a shaft carried by the frame provided with an adjustable'frictionwheel for engaging the under side of said receptacle, a telescopic rod carrying a pounder at its lower end, a bracket secured to the rear side of the standard, having its upper end bent over said standard and formed into a bearing for the upper end of said telescopic rod, an L-shaped member, the vertical portion of which is fastened to said standard and has a gu'ideway and the horizontal arm of which has a bearing for said rod, an arm fastened to said rod and guided by said guideway, a Wheel having a crank-pin, a rod pivoted to said arm and crank-pin, and mechanism including a hand-crank, on said bracket for simultaneously rotating said Wheel and shaft, substantially as described.
