Specification of Letters Patent Patented J 7, HD2110 application filed July 11, 1919. Serial No. 316,099.

To all whom it may concern:

Be it known that I, BENJAMIN E. Gn'rz, a citizen of the United States, a resident of Morton, in the county of Tazewell and State of Illinois, have invented new and useful Improvements in Wringer Mechanism for T Vashing-Machines, of which the following is a specification.

This invention has reference to wringer mechanism for washing machines, and relates particularly to a means for locking the swinging wringer in its different adjusted positions, and to means for disconnecting the wringer driving means from the power, simultaneously with the release of the locking means.

That the invention may be more fully understood, reference is had to the accompanying drawings, in which,

Figure 1 is an elevation of so much of a washing machine and wringer mechanism, as will illustrate the application of my invention thereto;

Fig. 2 is a vertical sectional detail showing my improved wringer lock and the means for disconnecting the wringer drive from the power;

Fig. 3 is a detail elevation in section showin the locking means;

*ig. t is a plan in section of the parts seen in Fig. 3;

Fig. 5 is a detail elevation in section, showing the means for disconnecting the wringer drive from the power;

Fig. 6 is a plan in section of the parts seen in Fig. 5;

Fig. 7 is a detail elevation in section showing the clutch connection employed to connect the wringer drive with the power;

Fig. 8 is a plan in section of the parts seen in Fig. 7, and

Fig. 9 is a sectional detail of one of the gears and shaft connection employed to drive the wringer.

Like characters of reference denote corresponding parts throughout the figures.

Power operated swinging wringers for washing machines are, in most cases, mounted on an upstanding support incasing a power operated driving shaft and associated therewith, are clutch controlled gearing for operating the wringer in a manner so that the rolls may be reversed, and stopped at will. Because the wringer may be swung and operated in its different positions, it is quite necessary that the wringer be locked, in its different positions, and this invention is directed to such a means. It is advisable that when the wringer is being swung, that the driving gearing for the wringer should be disconnected from the power, and therefore, my invention contemplates a means by which the wringer driving gearing is automatically disconnected from the power simultaneously with the release of the locking means, permitting the wringer to be swung about its driving shaft: The reason it is advisable to disconnect the wringer operating gearing from the power, when the locking mechanism has been released, is that the wringer may be accidentally swung through the action of the vertical driving shaft, and the operator be thereby hurt. However, my improvement obviates this danger, as will be understood.

Tn the drawings, 1 designates so much of a washing machine as is necessary to illustrate the application of our invention, and 2 designates a part of a wringer, which is of the usual construction. That is to say, it has the rolls 3 and 4:, the latter having an extended shaft 5 on which are loosely carried the facing bevel gears 6 and 7, and therebetween is a slidableclutch member 8, feathered on the shaft 5 and adapted to be alternately moved into engagement with either of the bevel gears 6 and 7, to connect the same to the shaft 5. The clutch member may be moved, in the manner stated by the clutch shifting member 9. Meshing with the two bevel gears 6 and 7, is a bevel gear wheel 10 which has a spline and groove connection with the upper end of the vertically disposed drawing shaft 11. The connection, last described, between shaft 11 and bevel gear wheel 10 permits the shaft 11 to have movement through said bevel gear 10, while at the same time, provides an operating means therefor.

The bevel gears 6, 7 and 10 are preferably incased in the sectional casing 12 and 13, the latter section having a depending tubular casing 14 formed with an annular flange 15 adapted to rest on a similar flange 16 on the upper end of an elongated tubular casing 17 into which the lower end of the tubular casing 14 is telescoped, and has revoluble move ment. The casing it has connected thereto,

a bracket 18 supporting the wringer, and the casing 17 has bracket extensions 19 adapted to be bolted to the body of the machine. Telescoped into the lower end of the casing 17 is a tubular casing 20, receiving the lowerv end of the shaft 11 and also .a separate extension 21 of said shaft, on the lower end of which is a bevel gear 22 meshing with and adapted to be driven by a bevel gear 23 on the end of a shaft 24 which receives its power from a suitable motor or other source. The meeting ends of the shaft sections 11. .and 21 have the complementary clutch parts, or members, 25 and 26, which, when in clutch relation, will impart motion from the shaft 24 to the bevel gear 10 and the wringer shaft 5 through either of the bevel gears 6 and 7. When said clutch parts 25 and 26 are in detached relation, the shaft 11 is dis connected from the driving shaft 24, as is clearly obvious.v

The casing 17, opposite where the lower end of the casing 14 fits therein, is cut-out,

as at 27, and it is formed or provided with spaced ears 01' plates 28 providing a bearing in which is journaled the spindle 29 connected to an operators crank 30. The spindle 29 is held in operative posit-ion, preferably by the cotter-pin 31, and the body of said spindle is grooved as at 32, producing the cam-engaging surface 33 which may be brought into an impinging relation with the casing 14, when the crank is moved to the downward position, shown in the figures. Raising the crank 30 rotates the spindle 29, bringing the groove 32 opposite the face of the casing 14, releasing the same and permitting the wringer to be swung. The crank 'and spindle preferably merge into the eccentric collar 34, working in the eccentric ring or strap 35 on the upper end of the rod or bar 36, which, at its lower end is formed or provided with the angular yoke extension 37, embracing the casing 20, preferably above the clutch members 25 .and 26; and from said yoke extends the lug 38, which passes through a slot 39 in the wall of the casing 20 and operates between the collars 40 and 41 on the shaft'll. The ends of the yoke 37 are preferably connected by the bolt 42.

It is obvious that when the crank 30 is raised, the rod or bar 36 will be lifted, which in turn will raise the shaft 11 slightly, separating the clutch parts 25 and 26, thereby disconnecting the wringer driving gearing from the power, and simultaneously with the release of the locking means for the wringer. The gearing 6, 7 and 10 is not disturbed, as the shaft 11 may move through the bevel gear 10, and such gearing is controlled by the clutch member 8 so as to regulate the direction of rotation of the wringer rolls, and stop the same at will, during the operation of the shaft 11, which is normally operating continuously when the power is on, except when the lock for the wringer is released to permit the wringer to be swung.

It is believed the operation of the mechanisms herein claimed is sufliciently under stood without further detailed description.

It is obvious that various changes may be made without departing from the spirit and -against rotation, and means to disconnect said shaft from its operating means, simultaneously with the release of said lock.
