ments in Washing-Machines, of which the following is a specilication.

My invention relates to washing-machines oi' the rotary reciprocating type; and the object of the invention to provide improved means for operating the rubber-shaft, to the end that the machine can be operated with g'reater ease without in any way impairing its efficiency.

A further object is to provide an operating means for the rubber-shaft that is inexpensive to manufacture and assembled without the necessity of accurate iitting and adjusting'.

The invention consists generally in various constructions and combinations, all as herein after described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this speciiication, Figure 1 is a vertical section of a washing-machine embodying' my invention. Fig. 2 is a horizontal sectional View on the line a' of Fig. 1. Fig. 3 is a similar View showinga modiiied means of con- -necting the operating-crank for the rubberhead shaft with the stationary base ofthe machine. Fig. t is a similar view of another modification. Fig. 5 is a sectional view of the mechanism shown in Fig'. 2 in another position, the lever connecting the pivot of the tub with the coil-spring being shown at the limit of its movement in one direction. Fig. 6 is a similar view showing the lever at the limit of its movement in the other direction. Fig. 7 is a view corresponding to Fig. 5 of the mechanism employed in Fig. 3. Fig'. 8 is a view corresponding to Fig'. 6 of the mechanism illustrated in Fig. 3. Fig. 9 shows the modiication illust 'ated in Fig. 4L with the lever connecting the tub-pivot and spring in the position shown in Figs. 5 and 7. Fig.` 10 is a view corresponding to Fig. 8 of the modi- `lication of Fig. 4. Fig. 11 is a sectional view on the line y/ y of Fig. 1.

In the drawings, 2 represents a tub having' a movable cover 3, provided with a fiat top for use as atable, and drop handles Il, that are arranged to swing down below the level of the top when the apparatus is not in use as a waslling-machine. The walls of the tub on the inside are provided with vertical corruga- `tions 5, common to tubs of this type, and a suitable draw-ofi'l plug 6 is provided in said wall near the bottoni of the tub. Ahollow standard 7 is centrally mounted in said tub and extends up above the normal water-line, and within said standard .lA arrange a shaft 8, having its upper end projecting' above said standard and carrying a sleeve 9, that rests upon said standard and is secured to said shaft. rlhis sleeve is provided with vertical flanges 10, that form guides for a rubber-head 11, that is vertically slidable on said sleeve with the rise and fall of the clothes in the tub. A shoulder l2 is provided at the lower end of said sleeve whereon said rubber-head rests when the machine is not in use. A casting 13 is secured to the bottom of the tub on the outside and carries a depending' stud 141, whose lower end {its within a socket 15, provided on a legcasting 16, having' suitable legs 17. An annular groove 18 is provided in said stud to receive a locking-bolt 19. The socket 15 is supplied with a suitable lubricating material te facilitate the easy operation of the tub. A. lever 2O is loosely Vmounted on the stud le near its upper end and connected to one end of a coil-spring 2l, the other end of which is attached to a lug 22 on the tub. Pins 23 are mounted on the casting 16 on opposite sides of the lever Q0 and limit the movement of the same in either direction. During the first part of the movement of the tub in both directions the lever 20 will swing freely on its pivot, and the power of the spring will not be exerted on the tub. Assoon, however, as the lever 2O strikes one of the stop-pins 23 its movement with the inner end of the spring will be arrested and the continued movement of the tub will put the spring' under tension and aid theV operator in overcoming the momentum of the tub in reversing the stroke.

In some instances I may dispense with the lever 2l) and provide a 'hole 24 in the leg-casting, in which the end of the spring may be hooked. The operation will be thesame, ex-

cept that the inner end of the spring will re- IDO main stationary instead of swinging to and fro with the lever.

The lever 20 may be mounted on the stud 14 in any suitable way; but I prefer to provide a slot 25 therein of sufficient width to allow the end of the lever to be slipped on or offI the stud conveniently. Then the spring is unhooked and its tension relieved on the lever, the latter will drop off the stud itself, but cannot do so as long as the spring is in use.

Upon the lower end of the rubber-shaft 8 I secure a crank 26, having a pin or lug 27 at its outer end carrying an antifriction-roller 28, and upon the casting 16 I provide a rib 29, that forms a guideway for the end of the crank and causes the shaft 8 to be oscillated by the movement of the tub. As shown in Figs. l and 2, I prefer to provide an extension 30 on this rib, running around the pivot of the tub, so that in the event ofbreakage of the spring the crank 26 can continue its movement around said pivot without danger of breaking any part of the mechanism, which might happen if the rib 29 ended abruptly at the limit of the usual stroke of said crank. In Fig. 3 I have shown a slight modification in the mechanism employed for operating the rubber-head shaft, which consists in providing a longitudinal slot 31 in the crank 26 to receive an antifriction-roller 32, mounted on a fixed pin 33 in the casting 16. The operation of this mechanism will be the same as that above described, except that the roller is on the stationary casting and slides in the crank instead of being mounted on the crank and sliding in the casting. Figs. 5, 6, 7, and 8 illustrate, respectively, the different positions of the mechanisms shown in Figs. 2 and 3. In Fig. 4 I have shown another construction, which consists in pivotally connecting the end of the crank 26 with one end of a link 34, that is pivoted at its other end to the casting 16. The different positions of this mechanism appear in Figs. 9 and 10. rIhe use of this crank-arm with the connection at its outer end allows me to increase the leverage on the rubber-head, and thereby provide an easier running machine without the necessity of materially increasing the speed of reciprocation. The crank connection is more simple and less expensive to manufacture than the gears, and in the limited space on the leg-casting I can obtain a greater leverage by the use of a crank lthan with a gear. The leg-casting is also provided on one side with a slot 35 to receive a locking-bar 36, supported in

guides

37 and 38 on the bottom of the tub.
