MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed April 14, 1906. Serial No. 311,692.

To all whom it may concern:

Be it known that I, WILLIAM A. WRIGHT, a citizen of the United States, and a resident of Greeley, in the county of Greeley and State of Nebraska, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.

This invention relates to mechanical movement and is particularly useful in connection with washing machines7 churns and the like, in which an alternating rotary movement of certain parts is necessary.

The object of the invention is to provide a simple and efficient mechanical movement for driving washing machines, churns or devices of similar character from a manually operated jointed frame having a flexible connection with a driven spindle.

The invention consists in the construction and combination of parts which will be described hereinafter andinore fully pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures. I

Figurc l is a perspective view of the upper part of a washing machine7 showing my invention applied thereto; Fig. 2 is an enlarged plan view of the machine with a part broken away and showing a portion of the mechanism in a di lferent position in dotted outline'7 Fig. 3 is a vertical cross section of the upper portion of the washing machine on the line 3-3 of Fig. 2; and Fig. 4 is a like view of a similar section on the line 4-4 of Fig. 2.

Referring more particularly to the drawings, l represents a washing machine tubr having a top 2. The top has a lid 3 set into it and hinged thereto. Upon this lid are supports 4 which carry a transverse member 5 rigidly attached to the supports. Within the tub there is an agitating device mounted upon a spindle 6 and consisting of a disk 7 having projections 7l adapted to catch in the garments and agitate them in the water when the device is given an alternating rotary motion. The spindle 6 passes through the lid 3 and the transverse member 5 in suitable bearings. The upper eX- tremity of the spindle carries a Washer 8 rigidly attached thereto which bears upon the upper surface of the transverse member 5, and in this way the agitating device is suspended from the lid, free to rotate with the spindle in the bearings. Between the transverse member 5 and the lid a pulley disk 14 is rigidly keyed to the spindle for a purpose to be explained hereinafter.

A jointed frame 9 is pivotally mounted'between the lid and the transverse member by means of pivot bolts l0 passing through the centers of two opposite sides, This jointed frame, which is normally of an approximately square form, has members ll and l2 joined at their corners by pivot bolts or screws i3. The opposite members ll carry half pulleys l5 projecting inwardly and rigidly mounted thereon. One of the pivot bolts l0 is rigid with the side l2 and has mounted thereon an operating handle bar i6 terminating in knobs 17 adapted to be grasped by the hands of the operator.

As the pivot bolt carrying the handle is rigid with the frame, when-the handle is turned the frame member rigid therewith will also be turned about this pivot, and as the remaining members of the frame have jointed connections therewith and with each other, the result will be a displacement of the frame work about the pivots l0 in the form of a rhombus as indicated by the dotted outline in Fig. 2. The half-pulleys l5 and the pulley 14 on the spindle are flexibly connected by bands i8 of leather or similar material, which pass partially about the peripheries of these pulleys and are secured respectively thereto, hence any movement of lateral displacement of the frame is transmitted to the pulley 14 and results in a rotary movement of the agitating device. It will be understood that the opposite members of the frame when it is moved are displaced in opposite directions, consequently the corresponding bands from these sides to the central pulley, give to said pulley a double impulse upon opposite sides thereto but in the same direction, and this obviously results n a more even distribution and a better application of the work necessary to operate the machine.

It will be understood that the bands or straps from the pulley 14 might be directly connected to side members of the frame without the employment of half-pulleys as shown in Fig. 5. In the normal position as shown in Fig. 2, thev axes of the frame are at right angles. 4When the frame is displaced, the angularity of the axes is changed while the angularity of the handle with the side of the frame to which it is secured remains constant. A

Having thus described my invention, l claim as new and desire to secure by Letters Patent:

l. A device of the class described, comprisinga revoluble spindle having` a head, a jointed frame ilexibly connected with said head, and a handle rigidly mounted upon said frame and adapted to displace the same to operate said spindle.

2. A device of the class described, comprising a revoluble spindle, a pulley mounted upon said spindle, a pivoted frame having; jointed members, iiexible bands attached to said members and said pulley, and a handle rigidly secured to said frame and adapted to actuate the same.

3. A device of the class described, comprising a revoluble spindle, a pulley mounted upon said spindle, a pivoted respectively thereto, and a pivoted operating handle rigid 10 irume having `iointed members, u member of said frame with said frame. having n half pulley, a flexible bund attached to the pe- In testimony whereof l have signed my name to this riphery of said hull` pulley und said pulley, and u handle specification in the presence of two subscribing Witnesses. adapted to tctunte said frame.
