IMPROVEMENT IN vWASH-INC--IVIACHINES.

Specification forming part of Letters Patent No. l 88,448, dated March 13, 1877; application filed February 15, 1877.

To all who-m it may concern.: i

Be it known that I, WILLIAM W. WALKER, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Washing-Machines and I do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in Which- Figure l is a sectional view of a washingmachine to which my invention has been applied. Fig. 2 is a similar view of a Washingmachine of different construction; and Fig. 3 is a side view of my invention detached. I

Similar letters of reference indicate corresponding parts in all the gunes.

This invention relates to certain improvements in that class of washing-machines in which the cleansing of clothes is effected by rubbing; (usually oftwo corrugated surfaces facing each other, the clothes being placed between them and' it consists in the construction and arran gement of vparts hereinafter more fully shown and described.

'.lo illustrate my invention I have, in the drawings hereto annexed, shown it applied to washing-machines of two different construc-l tions. In Fig. 1, A is the body of awashingmachine, consisting of two parallel inclined sides, a a', and a semi-cylindrical bottom, b. The side a has a series of ribs or corrugations, c, presenting a surface similar to that of .an ordinary wash-board. The side a has upon the outside a cross-brace, k, in which is secured a cylindrical screw-threaded sleeve, E, the end of which rests irmly against side a. In this sleeve worksv a screw-threaded cylinder, F, having a longitudinal perforation, through which passes ashaft, D, which projects through a perforation in side a into box A. y, Here it has a solid wooden disk, C, provided with ribs or corrugations d, facing those upon side a. The shaft D may be secured in cylinder F in any suitable position by a set-screw, D'.

cl' is a rubber washer or cushion, placed inV the end of sleeve E, and resting against side a. This washer or cushion has the double object: to prevent water from getting into the 'threads of sleeve E, and to serve as a cushion for cylinder F when the machine is operated.

The operation of my invention, when applied in the manner just described, is as follows: After turning the shaft D and cylinder F, in which it is secured by set-screw D by a suita bly-arranged crank or handle, until the disk G is brought as far as possible from side a of the machine, the clothes are placed in the box. The set-screw D is then loosened, and the shaft D, with disk C,I adjusted at a suitable distance from side a, according to the quantity of clothes in thebox. rlhe shaft D is then again fastened by screw D. By rotating the shaft in one direction .by its handle the disk C is Abrought away from the clothes in the box, and when the direction-is reversed it is brought down against them with a combined pressing and rubbing motion, which nearly resembles in its results washing by hand. 'lhe rubber cushion d', by stopping the progress of cylinder F, prevents the disk C from being forced too heavily against the clothes, by which they might be injured, andat the same time gives a certain impetus to the back motion of the'disk and shaft. t

When applied to a reciprocating' rubber -Washing-machine,.as illustrated in Fig. 2, the operation of my invention is somewhat different. In this case, A is the box or tub of the Washing-machine, having rubbing-surface I, H is the rubbing-board, which is pivoted to the lower end of shaft D, it being provided with strips or braces h It to retain it in position. The sleeve E, with cylinder F and shaft D, is pivoted 'at a point, e, between the sides of the box, in suitablebraces or bearings. The shaft D is provided with a gripe or handle, i. After placing the clothes in the box and adjustin g the rubbing-board H by raising or lowering shaft D by set-screw D', the shaft D is reciprocated, turningl at the same time the gripeor handle z' to any desired extentthus forcing the board yH down against the clothes, which are thus pressed and rubbed at the same time, the force ofthe pressure being easily regulated by handle t'.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a washing-machine having two rubbing-snrlces, one solid and the other rotating In testimony that I claim the foregoing as or reciprocating, the cylindrical screW-threadmy own I have hereto aixed my signature in ed sleeve E, longitudinally-perforated screwpresence of two Witnesses.
