SPECIFICATION forming part of LettersPatent No. 477,752, dated June 28, 1892. Application filed March 20, 1891. Serial No.385,817. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, OSCAR F. GLIDDEN, a citizen of the United States, residing at Grand Rapids, in the county of- Kent and State of Michigan, have invented certain new and useful Improvements in lVashing-lvlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art Io to which it appertains to make and use the same. Y

My invention relates to improvements in Washingnnachines, and more particularly to the mechanism for lifting the agitator to re- I5 lease it from the clothing.

The object of my invention is to provide a device that can be cheaply constructed, that Will operate with but little friction, and having certain neiv and useful features hereinafzc ter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in Which- Figure l is an elevation, partly in vertical section on the line g/ y of Fig. 2, of a device embodying my invention; and Fig. 2, a horizontal section of the same on the line :Je of Fig. l.

Like letters refer to like parts in both the figures.

3o A is the iop of the tub; B, a suitable frame upon which is journaled the oscillating driving-Wheel C, having the operating-lever D and engaging a pinion E on the vertical hollow shaft E', which shaft terminates in the 3 5 parallel pins F F, upon which the verticallymovable agitator G is suspended by a rod I in the axis of said shaft, which rod at its upper end passes through studs J and J', one above the other on the vertically-movable 4o plate I., located in the box-head M of the frame, and having a tongue at its rear engaglngavcrtical groove N in said head to guide said plate in its vertical movement. On the upper stud J is a roll K, With the under side of which engages one end of the arm Q, which arm extends through a suitable slot in the box-head M, is pivoted to the frame at its outer end, and operated by the downwardlyn projecting lever R, Which is connect-ed to said arm by means of bosses on the adjacent sides 5o of each, having a tongue and groove Tin their adjacent faces and held together by a bolt S. These bosses pass through the frame and serve to pivot said arm and lever to the same, and the tongue and groove serve to prevent change of relative position of the arm and lever. O is a roll and P a curved plate on the driving-wheel, which engage the lever R, and through it thearm Q lifts the plate L and the parts attached. By the use of two 6o studs the plate L is held in line With the rod I, and by lifting said plate by the pivoted arm as arranged I avoid any tendency of said plate to cant over and bind, and also minimize the friction. The roll O first strikes the lever R, and as the lever turns the roll passes oit the end of the same, when the plate P engages the lever, completes the movement of the same, and guides it back to the roll on the return stroke. 7o

l/Vhat I claim isl. In a Washing-machine, a vertically-mov-a able agitator having a suspension rod attached, an arm pivoted to the frame at one side of said rod and connected to the same, a lever attached to said arm, and a projection on the driving-wheel engaging said lever, sub stantially as described.

2. In a washing-machine, a verticallyanovable agitator having a suspension rod at- 8o tached, a vertically movable plate having studs engaging said rod, an arm pivoted to the frame at one side of said plate and connected to the same, a lever attached to said arm, and a roll on the driving-Wheel engaging 8 5 said lever, substantially as described.

3. In a Washing-machine, a vertically-movable agitator, a suspension-rod attached to the same at its lower end and engaging studs on a vertically-movable plate, said plate hav 9o ing a tongue engaginga vertical groove,'and a friction-roll engaging a pivoted lever, having attached an arm adapted to engage a roll and curved plate on the driving-Wheel, substantially as described.

4C. In a Washing-machine, an arm adapted to lift the agitator, a lever connected to said In testimony whereof I affix my signature in arm by bosses having a tongue and grooven presence of two Witnesses. their adjacent surfaces, a bolt through the a saine, said bosses serving to pivot the arm OSLAR F' GLIDDEN' and lever to the frame, and a projection on XVitnesses:
