specification.

This invention relates to mechanical movements and is particularly applicable to washing machines and like devices for transmitting a back and forth movement of the hand lever to an oscillatory vertical shaft.

Referring to the accompanying drawings Figure 1 is a side elevation of a washing machine to which my improved mechanical movement is applied. Fig. 2 is a top plan view of the same, partly broken away, and showing the operating lever in horizontal section. Fig. 3 is a vertical section on the line of the arrows 33 of Fig. 2 partly broken away and Fig. 4: is a detail section on the line of the arrows 414: of Fig. 2.

The reference numeral 1 designates the tub of the machine supported by legs 2, and having a hinged cover 3 having a reinforcement 1 on its under side to provide an elongated bearing for the bearing sleeve 5 of the shaft 6. This sleeve 5 extends through the cover, and is provided with a projecting arm 7 upon the outer end of which is mounted a roller 8 by means of a pintle 9. At its upper end the sleeve terminates in a boss fitting in the curved slot of the swinging plate.

The numeral 10 designates a bracket through which the sleeve 5 extends, and which is secured to the machine cover by bolts 11 which also secure to the bracket 10 a plate 12 formed with a transverse groove or channel 13 and with an opening within which the upper end of the bearing sleeve has bearing (Fig. 4:). One end of the bracket 10 is formed with an angular extension 14 and pivotally secured by a bolt 15 to this extension and to that portion of the plate 12 resting by therein, is an oscillatory square plate 16 formed with a curved slot 17 and an inclined slot 18 intersecting the slot 17, at the center of the latter. The roller 8 extends through the slot 18 and is guided therein, and within the slot 17 eX- tends a bushing 19 formed on the bracket 12. To one corner of the plate 16 is pivotally secured one end of a link 20 the opposite end of which is pivoted between parallel horizontal arms 21 projecting from a sleeve 22 mounted upon a pin 23 which connects the two members 24 and 25 of an operating, ever 26, said two members being connected by bolts 27 and provided at their upper ends with a handle 28. The lower ends of the lever members are connected by a cross pin 29 which is supported within the bend 30 of a curved resilient catch 31 secured at one end to the cover and provided at its opposite end with an arm 32 having an upturned lug 33 adapted to engage a hook 3 1 secured to the tub as shown in Fig. 3. The shaft 6 is square in cross section, and carries at its lower end any suitable agitating device 35, and at its upper end a suitable handle 36 by means of which the shaft may be raised to facilitate the raising of the machine cover. The cross-pin 29 serves as the fulcrum of the operating lever and as it is obvious from the showing in Fig. 1 the movement of said lever oscillates the plate 16 upon its pivotal support with the result of oscillating the shaft 6 and agitator 35 through the intermediacy of the boss 19 within slot 17 and the roller 8 guided within the slot 18. As a means for locking the arm 32 in engagement with the hook 34, I employ clamping device comprising a link 36 passing through openings in the catch 31 and a cam lever 37 pivotally secured upon a cross-pin 38 at the lower end of the link 36, and adapted to hold the arm 32 and hook 34 in engagement, thus locking the cover in closed position. When the cam lever is turned downward, the resiliency of the arm 32 releases it from the hook 3e and permits the cover to be raised.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In an operating device for washing machines, a suitable support, a vertical shaft rotatably carried thereby, a crank on said shaft, a substantially square plate pivoted at one corner on said support and having a pin-and-slot connection with said crank, a vertically disposed lever fulcrumed to said support and a link connecting said lever to said plate at a corner whereby the operation of the lever causes said shaft to oscillate.

2. In an operating device for washing machines, a suitable support, a vertical shaft rotatably carried thereby, a crank therefor,

a plate pivoted on said support and having a pin-and-slot connection with said crank, said plate being pivoted to said support at a point spaced apart from said shaft, a lever fulcrumed to said support and a link connecting said lever to said plate at a point spaced apart from said shaft, whereby the operation of said lever causes said shaft to oscillate.

3. In an operating device for washing machines, a suitable support, a vertical shaft rotatably carried thereby, a crank therefor, a bracket secured to the top of said support,

-' a substantially square plate pivoted at one corner to said bracket and having a pin-andslot connection to said crank, a vertically disposed lever fulcruined to said supportand a link connecting said lever to said plate at a corner remote from to said first mentioned corner whereby the operation of the I lever causes the said shaft to oscillate.

4. In an operating devlce for washing machines, a suitable support, a vertical bearing angles, a lateral arm projecting from said sleeve and provided with an upwardly projecting portion near its outer end designed to travel in said straight slot, a boss surrounding the upper end of said bearing sleeveand extending into said curved slot,

'a lever fulcrumedat one side of said support, and a link connecting said lever with said plate at a point spaced apart from said shaft whereby the operation of the lever causes said shaft to oscillate.
