JOHN H. HENDRICKSON, F CLEVELAND,

OHIO, ASSIGNOIR- TO THE HENDRICKSON GEARING FOR LAUNDRY MACHINERY.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed August 25, 1919. Serial No. 319,615.

To all whom it may concern:

Be it known that I, JOHN H. HENDRICK- SON, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Gearing for Laundry Machinery, of which the following is a specification. I

This invention relates to clothes washingmachines of the rotary cylinder type, and it has particular reference to the novel construction of the mechanism for operating the rotating cylinder and the wringer con- I nected with the machine.

The primary object of the present invention is the provision of a simple, durable, economical, and convenient motor driven mechanism for revolving and automatically reversing, or oscillating the Washing cylinder, and for operating the wringer in both directions of revolution of the rollers.

A further object is to provide simple means for shifting the wringer and cooperating mechanism to a number of positions, as desired, without disturbing the cylinder operating mechanism.

With these objects in view, the invention consists in the construction, combination and arrangement of parts as hereinafter described and set forth definitely in the ap pended claims, reference being had to the accompanying drawings which are made part of the specification, similar characters of reference being employed to designate corresponding parts.

In the said drawings Figure 1 is a side elevation of the improved machine.

Fig. 2 is an end elevation in direction of arrow m, Fig. 1, showing the body of the machine partially broken away.

Fig. 3 is a central vertical section on line 3 3, Fig. 5.

Fig. 4 is a fragmentary view in directionof arrow m, Fig. 1, with a portion of the gear housing broken away.

Fig. 5 is a plan view, and Fig. 6 is a section substantially on line 66 of Fig. 2.

Figs. 7, 8 and 9 are fragmentary views illustrative of a clutch operating means employed. 7

Referring now to the, drawings, 1 represents a metallic tub supported by a frame structure 2, and having mounted therein, on a horizontal transverse axis, a rotatable cylinder 3, said cylinder being perforated and said connection in detail.

provided with a sliding door 4. The design and arrangement of the elements thus far set forth are old in the art, and are not pertinent to the present invention, except as in combination with the improved mechanism.

In carrying out my improvement, which is adaptable to cooperation with the common elements above mentioned, a housing 5 is provided, which is rotatably mounted on a vertical bearing bracket 6, said bracket being firmly attached to the frame 2 so that the housing 5 can rotate above the top of the machine. A shelf 5 is connected with the housing 5 and provides a support for the motor 7. v

A vertical shaft 8 is journaled in the housing 5 and in the bracket 6, and has a worm wheel 9, keyed or otherwise secured thereto, in the upper part of the housing, as best shown in Fig. 3. The worm member 9 is the main driving element and is operated by an engaging worm 10 driven by the motor 7.

A pair of oppositely disposed bevelgears 11 and 12 are carried by the shaft 8, said gears co-acting with a companion gear 13 on a horizontal shaft 14, to drive the wringer, the shaft 14 being connected-with the lower wringer-roller 15. As there are several ways of connecting the said shaft and wringer-roller, that are common ifi shop practice, it is not deemed necessary to show The oppositely disposed bevel- gears 11 and 12 in mesh with the gear 13 provide means for reversing the direction of revolution of the wringer rollers, through their co-action with clutch mechanism. The said clutch mechanism in- .cludes a sleeve 16 mounted on the shaft 8 vided with annular flanges 16 and 16 A.v

stub-shaft 17 is journaled in a boss 5 and carries an eccentric pin 17%Wvhich operates on the flanges 16 and 16'. An operating handle 18 is attached to the shaft 17, said handle being provided with a projection 18 which is adapted to engagement, respectively, in the grooves a, b and c in the face of the boss 5". When the handle is in the position shown in Figs. 4 and 7, the projection 18 is in groove a, the sleeve 16 is in a neutral position, and the wringer is inoperative. It will be seen that the projection may be withdrawn from engagement with groove a and the handle turned either to the right or left, as desired, the projection automatically engaging with either groove 6 or c, as the case may be. "When in engagement with groove 6 the eccentric pin 17* causes the sleeve 16 to engage gear 11, and thus drive the wringer roll in one direction, and when engagement is made with groove 0, gear 12 is actuated, resulting in reversing the direction of revolution of said wringer rollers.

A bracket 19 is attached to the frame of the machine and connected with the bracket 6, as shown by the flanges 6 and 19 A horizontal stub-shaft 20, journaled in said bracket 19, carries a bevel-gear 21, said gear being in mesh with a companion gear 22 on the lower end of the shaft 8. Provision is made by the last named gears for driving the washing cylinder 3, through the novel combination and arrangement of elements as follows.

Mounted on the cylinder trunnion 23 is a pinion 2 1. Said pinion normally is free on the trunnion, but is operatively connected therewith through the medium of the clutch 25 being actuated by a lever 26. A rocker member 27, pivoted on the frame of the machine at 28, is provided with a segmental gear rack 27 which meshes with the pinion 24. An arm 29 is attached to the bevel-gear 21, and connection is made between said arm 29 and the rocker member 27 by an eccentric connecting bar 30, said bar having pivotal connections at 29 and 30. It is obvious, that, with the clutch 25 thrown in, and the gear 21 revolved, the cylinder 3 will be oscillated on its axis, through the medium of the co-action of the connecting rod 30, the rocker 27, and the pinion 24:, the gear 21 being driven by gear 22 carried by the vertical main shaft 8.

Provision is made for swinging the wringer horizontally to any position without disturbing the cylinder operating mechanism. This is brought about by the wringer 31 being firmly attached to the housing 5, said housing being adapted to revolve on the stationary bracket 6, with the shaft 8 as an axis. The motor 7 being attached to the shelf 5*, which is part of the housing 5, is retained in its operative connection with the driving mechanism. Means are provided for locking the housing in three most desirable positions, as best shown in Fig. 3. The said means comprise a vertically movable pin 32 mounted in an extension 6 of the bracket 6. Said pin is adapted to penetrate cavities 5 formed in the base of the housing 5. The pin 32 is withdrawn from the cavities 5 by a lever 33 fulcrumed on the bracket 6 at 33, and a spring 3 1, acting on the pin, forces it into any one of the cavities when the lever 33 is released and a cavity is brought into registration with said pin, thus rendering the locking function automatic. 4

A friction clutch connection 35 is interposed between the motor 7 and the worm 10 as a safe-guard against the burning of the motor, if overloaded.
