WRINGER Filed March 1, 1954 Sheets-Sheet l INVENTOR Jay/v 5. 6,9; 77/\/0 BY W fill/LUV ATTORNEY Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE 12 Claims.

This invention relates to wringers and more particularly to a wringer of the type conventionally attached to a power-driven washing machine.

An object of the invention is to provide a wringer combining a maximum of safety and a quick means for reversing its rotation.

A further object of the invention is to provide a reversing mechanism which is operable by manually tilting a wringer roll in either direction from the vertical center line.

Another object is to provide a simplified and efficient reversing mechanism more economical of manufacture than are similar devices now in use.

In the drawings:-

Fig. l is a side elevational view of a wringer apparatus embodying my invention.

Fig. 2 is a view on line 2--2 of Fig. 1.

Fig. 3 is a view in vertical section of the reversing apparatus unmeshed.

Fig. 4 is a fragmentary View of Fig. 3 showing the device meshed to rotate the wringer rolls in one direction.

Referring more particularly to the drawings, the numeral l designates a vertical shaft which may be connected to any source of power. At the upper end of the shaft I0 is fixed a spiral gear II shown in dotted lines in Fig. 1. A pair of spiral gears l2 and I3, are set at right angles to gear H and are in constant mesh therewith. The gears l2 and !3 are fixed on shafts M and I 5, the latter being rotatively mounted in the wringer head it.

The wringer proper is supported in a frame ll, having a base board IS. The lower wringer roll l 9 has a shaft 2!] fixed therein which is freely supported in the bearings 2! and 22 which, in turn, rest on the trapped

coil expansion springs

23, 23, 24, (not shown) and 24. The upper wringer roll 25 has a shaft 2501. which is journalled in the

cams

26 and 21, which latter are integral with the handle member 28. In the position shown in Fig. 3 the upper roll 25 may be freely lifted out of the assembly by means of the handle 28.

The frame H is provided with longitudinally extending inwardly disposed detent pins 29, 29', 30', (not shown) and 30.

The shafts l4 and i carry a pair of spur gears 3! and 3!, on the ends thereof adjacent the upper wringer roll 25. A spur gear, 32, is fixed on the end of shaft 25a, adjacent the gears 3| and 3! the latter being so spaced as toseparately mesh with gear 32, if and when the handle 28 and roll 25 are tilted in either direction from vertical central alignment.

The cams 26 and 2'! have detents as at 33 and 33' designed to impinge against the

pins

29, 29', 30 and 30.

In operation, the source of power will rotate the shaft H] with the spiral gears ll, l2 and I3 and the spur gears 35 and 3|. Assuming that the handle 28 is in vertical position, the gears 3| and 3| will rotate free and clear of the spur gear 32. To rotate the wringer rolls it is necessary to tilt the handle 28 transversely of the rolls, thus forcing the detents on one side of the handle under the adjacent detent pins. This action will securely engage the spur gear 32 with the rotating spur gear 3| or 3|. The spur gear 32 will always engage the gear adjacent the upper side of cam 26. In the engaged position the mesh is securely held by the pinioning of the detents under the related pins, and the contact of the upper sides of the cams 26 and 2'! with the opposite pins together with the contact of the upper and lower rolls 25 and I9 as well as'the contact of the meshed gears.

It is to be understood that other methods and structures may be employed to maintain the gears in mesh.

Various modifications in structure and design may be used in producing the device Without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:
