lM-PROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 39,4 89, dated August 11, 1863.

To all whom may concern: Belit known that 1, J. H. MALLoRY, of South Bend, in the county ot St. Joseph and lState of Indiana, haveyinvented a new and Improved Clothes-Washing Machine; and I do hereby declare that the following'is a full, clear, and exact description of the same.

Figure l is a side sectional view of uiy invention taken in the line Fig. 2, and Fig. 2 aplan or top view ofthe same.

Similar letters ot reference indicate corresponding parts in the two' figures.

This invention relates to an improvement in that class of clothes-washing machines in which a rotary tinted cylinder is employed in connection with pressure-rollers.

',The object of the invention isA to obtain a machine of the kind specitied which will cause the clothes to be operated upon with a more equal and uniform pressure .than hitherto, the pressure at the same'time ex teudingnearly or quite around the entire circumference ofthe iiuted cylinder.

To enable those skilled in the art. to fully` understand and constructmy invention, I will proceed to describe it.

A represents a sulle-receptacle of quadri lateral i'orm,and having inclined 'ends a a, and a rounded bottom, b, as shown clearly in Fig. l.

B is a cylinder, the periphery c of which isfluted longitudinally or parallelly with its shaft d, said shaft passing through verticall oblong slots e in the sides ofthe receptacle A, and having springs f attached to it.v

C represents polygonal pressure-rollers, the axes of which are connected to curved or segment bars g h at opposite sides of the cylinder B. These segment-bars g h `are connected together in pairs by pins i, and one bar, g, of

each pair has a short arm, and these arms are ,pivoted in curved bars D, which are placed in the ends-receptacle A, two at each side of the cylinder B. The lower ends ofthe bars D rest upon spiral springs E, and their upper parts are fitted loosely on horizontal pins F, attached to the upper parts of the ends a of the slide-receptacle, said pins having spiral springs k upon them, against which the bars D bear. (See more particularly Fig.

1.) The polygonal rollers C are connected to the curved or segment bars g h,as follows: The two upper rollers are connected directl .fro1lersC, at opposite sides of vthe cylinder B,

immediately'b'eiowhe two upper rollers, are connected to the ends of curved bars l, which i are connected at their centers by pivots m to the upper ends otl the bars h, as shown clearly in Fig. 1. The two rollers at opposite sides of -the cylinder B, immediately below those previously described, are connected to curved bars n, which are precisely like the bars l, and are attached by pivots o to the lower ends of the bars g. The-lowermost rollers U are connected directly to the lower ends ot' the bars-h. By this arrangement it will be seen that a uniform pressure ofthe rollers C is obtained all around the cylinder B, and the rollers are allowed to yield or givein such ,which are placed on the cylinder B, and se- .consequence of beingarranged with springs, as shown, allow the rollers to yield or give so as to conform to the thickness ot' the layer of cloth between them, and the cylinder B is al lowed to give or yield to a certain extent in a vertical direction, owing to the slots e. and springs f. The whole arrangement is extremely simple and etticicnt, and is well adapted for washing either ne or coarse clothes. I would remark that only one half ot' the rollers C may be used if desired, those at one side ot the cylinder B being removed. ln` certain cases ,this way may be desirable. The su'dsreceptacle A is supplied at alltiines with a requisite quantity ot' snds. The polygonal form of the rollers C renders their acl tionv far more eicient `than they otherwise would be, as they operate with an intermittent pressure. Y

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

`The cylinder B, having its periphery tinted longitudinally, in combination withl the pol ygonal rollers U, 'attached to curved or segment bars g h l, and the latter connected together and to the yielding bars D, said parts being placed at one or both sides of the cylinder B, and all arranged as and for the purpose specitied.
