D represents my reciprocating rubber. Its lower surface is undulating, and it is perforated at frequent intervals, so that the water may feed through the holes in the motion of the machine. E E are the handles of this rubber, and F the side pieces.

The handles, where flexibility of the rub bing parts is desired, may slide in slots b 12, Figs. 3 and 4, and the handles be connected by links G G to cross-head H, between which and the bottom piece I, attached to the under I 4 side of the tub, springs J are introduced around 5 studs j, on which the cross-head slides, and where no such flexibility as these springs give is desired the handles may be attached to sliding blocks 6, moving in grooves in the sides a,

a, as shown in Figs. 6 and 7; but I prefer the following construction: I provide two side bars, K, pivotedat k, and grooved to receive the trunnions k, which are adapted to slide and partially turn therein. The free ends of these bars are inclosed by the staples L, and

between the upper ends of these staples and the upper edges of the side M are introduced.

In the action her D is near the end a the desirable flexibility is obtained almost entirely from the springs 0; but when the rubber is at the other end it has but little power to compress springs c, owing to loss of leverage. It is then that the springs M are called into play, and they give bars coiled springs 'way freely in this condition, and less freely as of the machine, when the rub-' the rubber leaves this end. By reason of these two springs, therefore, the flexibility or yielding'character of the rubbing-surfaces is nearly uniform throughout the stroke.

To give the necessary adjustment of the rubber 1) before spoken of, I pivot the side pieces F to the handles E E at e, and make curved slots f in the side pieces, and with setscrews f, and by these slots and pivots I am enabled to swing the rubber D into the proper relation with the handles E E, and with the rubber-frame O.

In place of coiled springs c or J, the flat springs 0', Fig. 1, may be used.

I I claim- 1. The combination, substantially as specified, of the tub having a continuous inclined bottom, the rubber-frame over the deepest portion of the'tub, having a yielding support at the deepest end of the tub, and resting at the other end on the bottom of the tub and the reciprocating rubber.

2. The combination of vessel A, yielding rubber-frame G, reciprocating rubber-frame D E E, the latter having, at the end opposite frame 0, a yielding connection with the vessel A. substantially as and for the purpose specified.

3. The combination, substantially as specified, of the reciprocating rubber-frame, the handles pivoted and adjustably fixed to the standards thereof, the slotted pivoted ways, in which the cross-bar of the handles plays, and the springs M.

In testimony of which inventionI hereunto set my hand.
