f IMPVRQVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 135,808, dated February 1l, 1873.

and I do hereby declare the following to be a full, clear, and exact description of 'thefsame, reference being had to the accompanying drawing forming part of this specification, in Which- A Figure 1 isairont elevation of the machine constructed in accordance with my invention, and Fig. 2 is a transverse vertical section of Similar letters of reference in the drawing indicate corresponding parts.

My invention has for its object to improve the construction and efficiency of that class of washing-machines in which a single smooth roller is employed lin connection with a single `corrugated roller, the clothes to be washed proximate faces of the uprights G. The lower ends of these blocks are connected -by `the cross-piece J, and are guided in their movements to hold the smooth roller against the corrugated roller by means of the cleats I a-fxed to the inner faces of the uprights G,

'as shown. The smooth roller is held with a yielding pressure against the corrugated roller, by the spiral springs F interposed between the bar or cross-piece J, and a wide basepiece, E, secured to or forming a part of the sill H, so as to leave a space, K, between the two for 'the passage of water. The frame C J Vfor supporting the smooth roller is made exceedingly wide to prevent `it from twisting between the cleats I, as the clothes are passed between the two rollers. `If made narrow, this difficulty would occur to a greater degree and the frame become bound or cramped between the cleats, and therefore injure the eiiiciency of the springs F, or,frather, the yielding action ofthe smooth roller.

The working-surface of the corrugated roller terminates a short distance from the ends of the latter, so as to leave a space between them, and the uprights G, while -the smooth roller is vmade considerably shorter, so as to work between the blocks C and not extend the entire length of the corrugations ofthe roller A.

By this construction and arrangement ot' the two rollers the clothes are prevented from beingcaughtand twisted or torn bythe jonrnals of either.

D D are thin strips of India rubber Vor other pliable material aflixed to oppositeV sides of the frame C J, so thatv their upper edges shall bear lightly against the .smooth rollerB, as shown, and prevent the clothes from being carried round with it. c is a crank secured to the journal of the upper roller, for the purpose of operating the machine, as will bereadily understood.

Having thusdescribed my invention, what I claim is-n The washing-machine, consisting of the long ,corrugated roller A, the short `smooth roller B, the supportingand guiding frame C J, the pliable bearing-strips'D, the springs F, the supporting cross-bar E, and the cleats I, the whole arranged with respect to each other within the frame G H, as herein shown and described, for the purpose set forth.

EDWIN HOYT.
