GEARING FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent N0. 794,823, dated July 18, 1905.

Application filed December 27, 1904. Serial No- 238,392.

To all whmn it may concern:

Be it known that I, WILLIAM H. Voss, acitizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and use vful Improvements in Gearing for Washing Machines, of which the following is a full, clear, and exact specification.

The object of my invention is to provide asimple mechanical movement for converting plish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the cover of a washing-machine tub with my improvements applied thereto. Fig. 2 is a plan view of the same with parts of the cover and supporting-frame broken away.

Referring to the drawings, A represents the cover of a tub of a washing-machine, and

B represents the base-plate of a supporting-- frame 0, which bridges over the same from end to end and affords bearings for the operative parts of my invention. The baseplate is arranged in a diametrical position on the cover, and the vertical portion of the supporting-frame arising from the end thereof nearest the circumferential edge of said cover is provided with horizontal bearings a for the continuously-revolving drive-shaft D. The inner end of drive-shaft D is provided with a beveled drive-gear E, which engages a larger beveled gear F, secured on the lower end of a vertical spindle G, which latter is journaled in vertical bearings 12 in the horizontally-disposed reach of thesupportingframe.

Pivotally secured to the cover at a point a suitable distance to one side of the vertical plane of the axis of the drive-shaft is a horizontal arm H, which extends under gear F and in the portion thereof working under said gear has a longitudinal slot 0, which is entered and engaged by a stud cl, secured to and depending from gear F. Arm H has a mem ber projecting back at an acute angle thereto, which extends horizontally from the end thereof nearest gear E, and the edge of this arm farthest from the pivot ofarm H is provided with a rack c, which latter meshes with an eccentric pinion J, fast on the stirrer-shaft K. This stirrer-shaft is journaled in suitable bearings in both the overhead horizontal reach of the supporting-frame C and the baseplate B thereof, and it extends down through the latter and through the cover A and has a slliitable stirrer-head connected to its lower en In operation the drive-sh aft is revolved continuously in a given direction and imparts its motion, through the medium of gear E, to gear F. The latter through stud cl vibrates arm H back and forth, and the rack e of the latter engages and rotates pinion J and stirrer-shaft K first in one direction and then in the other.

What I claim as new is 1. In a washing-machine, the combination with a suitable supporting-frame, a continuously-revolving drive-shaft j ournaled therein,

a pinion on one end thereof, a gear suspended from said supporting-frame the axis of which is at right angles to said drive-shaft, which is engaged by said pinion and has a stud projecting from its face, a pivoted arm movable in a plane transaxial to said gear, and having a longitudinal slot engaged by said stud, a rack projecting from said arm at an angle thereto, a stirrer-shaft and an eccentric pinion thereon engaged by said rack.

2. In a washing-machine, the combination with an overhead-supported continuously-revolving horizontally-disposed gear, and a vibratory arm actuated thereby and having a rack projecting at an anglefrom the same, of a rotary reciprocal stirrer-shaft, and an eccentric pinion thereon engaged by said rack.

3. In a washing-machine the combination with a supporting-frame comprising upright end portions and a horizontal portion connecting the upper ends of the same, and a continuously-revolving horizontally-disposed gear, the bearings of which are suspended from the horizontal portion of said supporting-frame, of a vibratory arm movable horizontally under said gear and actuated thereby and having a rack projecting laterally therefrom at an angle, a vertically-disposed rotary reciprocal stirrer-shaft, and an eccentric pinion thereon engaged by said rack.

4. In a washing-machine the combination with a supporting-frame comprising upright end portions and a horizontal portion connecting the upper ends of the same, and a continuously-revolving horizontally-disposed gear, the bearings of which are suspended from the horizontal portion of said supporting-frame, a stud secured to and projecting downward therefrom, of a vibratory arm movable horizontally under said gear and having a longitudinal slot therein which. is engaged by said stud, and having a rack projecting laterally therefrom at an angle; a vertically-disposed rotary reciprocal stirrer-shaft, and an eccentric pinion thereon engaged by said rack.

5. In a washing-machine the combination with a supporting-frame comprising upright tally under said gear and actuated thereby and having a rack projecting laterally therefrom at an angle, a vertically-disposed rotary reciprocal stirrer-shaft, and an eccentric pinion thereon'engaged by said rack.

6. In a washing-machine the combination with a supporting-frame comprising upright end portions and a horizontal portion connecting the upper ends of the same, a continuously-revolving drive-shaft journaled in one of the upright ends of said frame, a pinion on the inner end of the same, a horizontally-disposed gear the bearings of which are suspended from the horizontal portion of the supporting-frame and which is engaged by said pinion, a stud secured to and projecting downward therefrom, of a vibratory frame movable horizontally under said gear and having a longitudinal slot therein which is engaged by said stud and havinga rack projecting laterally therefrom at an angle, a vertically-disposed rotary reciprocal stirrer-shaft, and an eccentric pinion thereon engaged by said rack.

In testimony whereof I have hereunto set my hand this 21st day of November, A. D. 1904.

WILLIAM H. VOSS.
