L. P. KEYSER. BEARING FOR WASHING MACHINES. APPLICATION FILED APR-19, 1915.

Patented Nov. 23, 1915.

ATTORNEY W/T/l/ESSES LOUISP. KEYSER, OF WHEELING, WEST VIRGINIA.

GEARING FOR WASHING-MACHINES.

To all whom it may concern Be it known that 1, Louis P. Knvsnn, a

citizenof the United States of-America,and 1 resident of Wheeling, county of 0h10, and Stateof West Virginia, have invented certain new and useful Improvements in Gearing for Washin -Machines, of wh ch'the following is a specification.

' v This invention relates broadly to washing-machines, and specifically to a gearing for motor driven washing machines.

The primary object of the invention is to provide a simple gearing whereby the power of arotary motor is applied to the dasher shaft of a washing machine for oscillatingthe latter.

A further object of the invention is to provide, in association with a rotary motor having a drive-shaft whose direction of rotation is constant, a gearing whereby said shaft communicates oscillatory motion to the dasher shaft, or dolly shaft, of a washing machine.

W'ith these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of. this specification, in which Figure 1 is a top plan view of the invention applied to a tub; Fig. 2 is an enlarged section on the line 2-2, Fig. 1; and Fig. 3 is an enlarged detail view, in, top plan, of the worm gear, rack-bar and pinion.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views, 1 indicates the top of a tub of a common type and 2 a lid hinged thereon. Rigidly mounted upon said lid is the base 3 of a cast iron bracket 3 which has a vertically disposed sleeve-bearing 4 formed integral therewith, the lower end of said bearing extending below the base 4 3 and being adapted for seating in the lid 2 at a point-central with respect to the top 'of the tub. Rotatably mounted in said bearing 4 is a spindle 5 designed to have connected thereto or mounted thereon the lower end of the usual dolly-shaft (not shown) which carries the dolly or stirrer-head. Also Specification of Letters Patent.

Application filed April 19, 1915.

Patented Nov. 23, 1915.

Serial No. 22,253.

mounted upon the base 3 of the casting is a rotary motor 6 which, as herein shown, is of a fluid actuated type, but may be an electric motor if desired. The shaft of the motor carries thereon a worm 7 which operatively engages a horizontally disposed worm-gear 8 fixed on a spindle 9 which is journaled in a sleeve-bearing 10 carried by the bracket 3. Eccentrically connected to said Worm gear 8 is one end of a rack-bar 11 the teeth of which operativelyengage a pinion 12 fixed upon the spindle 5 at a point.

above the bearing 4.

A yoke 13 of substantially U-shape has the ends of itsparallel members pivoted on the spindle 5 above and below the pinion 12 and is disposed in embracing relation to the rack-bar, being designed to swing with said rack-bar for maintaining the latter in operative relation to said pinion, as is clearly indicated in F ig. 3. Antifriction rollers 14 are mounted upon vertically disposed pins 15 which have their ends mounted in the opposite yoke members, said rollers being designed to bear against the back of the rackbar, as shown in Fig. 3. I

It will be noted that all the parts constituting the invention are compactly organized, the bracket 3 having all the operating parts mounted thereon and being itself mounted upon the hinged lid 2 of the tub; conset ntly, when said lid is raised to permit a .ss to the tub, all said parts are moved to an out-of-the-way position. i

hat is claimed is In a gearing for washing machines, a cast iron bracket having a base portion adapted for mounting in a stationary position on the top of a supporting member and having a portion which overhangs said supporting member, a motor superposed on said base portion in overlying relation to said supporting member, a sleeve bearing formed in said bracket and extending centrally through said supporting member, a vertical spindle rotatable in said bearing, a pinion fixed on said spindle above the bearing in the bracket, a worm carried by the motor shaft, a worm gear rotatably mounted in overlying relation to the overhanging porated with said Worm, e raok binhaving its in testimony whereof, I afiix mysignatui' toothed face in engagement with said pinion in presence of two subscribing Witnesses. g
