GEARING MECHANISM.

Specification of Letters Patent.

Patented Sept. 2, 1913.

To all whom it may concern:

Be it known that I, HowAnn F. SNYDER, a citizen of the United States, residing at Newton, county of Jasper, and State of Iowa, have invented new and useful-Improvements in Gearing Mechanisms, of which the following is a specification.

The present invention relates to means for washing and wringing clothes, and has for its object the provision of a power driven wringer' so mounted and secured with re spect to a washing machine that it can be shifted from one position to another while still maintaining its driving connection with a motor or other suitable source of power.

More particularly, the invention embraces a wringer. supported above a washing machine on a frame which is movable outwardly, away from the washer, into operative position above asupplemental or auxiliary tub, with the result that the clothes cleansed in the washer can be wrung into an auxiliary tub for rinsing, or the like, and later can be Wrun out of the auxiliary tub into a basket or ot er suitable receptacle.

A further object is to provide a device of this kind wherein the wringer is carried on a swinging frame and is supported by the body or tub of the Washing machine. This and other objects hereinafter disclosed are attained by the embodiment of the present invention disclosed in the following detailed description which is to be taken in conjunction with the accompanying drawings, wherein- Figure 1 is a side elevation of the gearing mechanism assembled in operative position with respect to a washing machine, and Fig. 2 is a plan view of those parts of the gearing which. lie below the body of the Washer tub.

In the construction shown, the washing machine comprises a tub I on suitable legs 2 provided with stifiening cross-pieces 4 and with a cover 5 surmounted by the usual gearing 6, whereby the agitator or dolly within the tub can be driven in the usual manner. The gearing below the tub body, as shown in Fig. 2, comprises an irregular casting having arms 7 and 8 for attachment to'legs of the tub and having bearings 9 and 10 for the main driving shaft 11 whereon is keyed a large gear wheel 12 meshing with a motor inion 13 driven by a motor 14 slung from t e brackets 15 and 16 which envelop, and are in the nature of supplemental bearings for, the main shaft'll. Bevel gears 17 and- 18 rotatably mounted on the main shaft 11 mesh continuously with a large bevel gear 19 keyed to a transverse shaft 20, on the outer end of which is a crank disk 21 carrying a crank pin 22 from which a driving link extends upward to make driving connection with the gearing 6 at the top of the tub in a manner which need not here be set forth in detail. A clutch member 23, slidingly mounted on main shaft 11, but having a keyed connection therewith, can be moved along that shaft through the agency of a bell crank 24 to throw either of the bevel gears 17 or 18 into driving relation with respect to the main shaft 11 and its motor, for driving the transverse shaft 20 in either direction as desired. Asameans for swinging the bell crank 24, recourse may be had to connecting link 25 (Fig. 1) pivotally connected to the crank arm 26 of a rock shaft 27 extending upwardly along the side of the tub and having a hand grip 28 at the edge of the cover whereby the rock shaft 27 may be twisted to shift the clutch 23 as desired. The wringer 29 may be of usual construction, provided with wringer shafts 30 and 31 geared together, the lower shaft 31 carrying at its outer end a sprocket wheel 32 over which a sprocket chain can be passed to drive the wringer rolls in either direction. The'end standards of the wringer are rigidly mounted on a horizontal platform or support 34 carried at the upper end of swinging supports 35, preferably four in number, and arranged in parallel relation, two at each end of the wringer supporting platform 34. and connected therewith by pivotal connections 36. The lower ends of these parallel supports are pivotally mounted on castings 37 in the form of brackets, bolted to the chime of the tub and each anchored to a leg of the tub, as shown in Fig. 1. By virtue of this pivotal mounting of the wringer supports, the wringer can be swung outward, as shown in dotted lines, into operative position above an auxiliar or rinsing tub 38, supported on a suitable c lair or stool 39. The wringer platform 34 comes down with a horizontal movement onto the top of the auxiliary tub, irrespective 'of the exact height of that tub, within reasonable limits, and the wringer in its new position is thus conveniently arranged for wringing rinsed clothes out of the auxiliary tub, into a third receptacle not shown, such, for instance, as a basket or another tub.

The driving connection for the wringer,

not only while it is located above the Washer tub, b'ut also when swung outwardly above an auxiliary tub, includes the sprocket chain 33, above-mentioned, and a driving sprocket 40 mounted on the end of a horizontal counter-shaft 41 supported by bearings in the brackets 37. This counter-shaft 41, as shown in Fig. 2, carries a bevel gear 42 meshing with a bevel gear 43 which is keyed to an inclined auxiliary shaft 44, but is in sliding engagement therewith, so that shaft 44 can be moved longitudinally, as by means of a' rigidly mounted collar '45, provided with a shifting hand lever 46 (Fig. 2) pivotally mounted on the side of the tub. The

other end of auxiliary shaft 44 is equipped with .a bevel gear 47 pinned thereto, this bevel gear meshing with a bevel gear 48 integral with the crank disk 21. Through the driving connections above set forth, it is possible to start the wringer in either direction, or to stop it instantly, by suitable manipulation of the hand grip 28 at the top of the tub and within convenient reach of the operator, these manipulations bein effected through longitudinal shifting o the clutch member 23, either to the right or to the left, or to an intermediate position out of engagement with both bevel gears; also, by shifting hand lever 46, the auxiliary shaft 44 can be slipped through the gear 43 far enough to disengage gear 47 from meshing engagement with gear 48, thereby discon-' necting the wringer from driving connection with the other parts of the mechanism and leaving the motor freeto drive the dolly within the tub. The driving connection for the wringeris operative and efiected irrespective of the exact position of the parallel movement, and the wringer can be swung outward or inward without consideration of the driving connections, and even while the wringer rolls are in motion.

I am aware that various features of the specific embodiment here disclosed may be varied without departing from the spirit of the present invention, and I desire to reserve as my invention such modifications and changes as reasonably come within the terms of the appended claims.

What I claim as new and desire to secure by Letters Patent. of the United States, is:
