MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 767,760, dated August 16, 1904. Application filed February 26, 1904. Serial No. 195,375. (No model.)

To all whom it may concern:

Be it known that I, J AMEs W. MARTIN, a citizen of the United States, residing at Omaha. in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

My invention relates to improvements in mechanical movements, and refers particularly to a mechanical movement adapted for'use in connection with washing-machines where it is desired to give a vertical and a reciprocating action to a shaft carrying an agitator.

The object of my invention is to improve this class of mechanisms and insure a smooth and easy action of the device and to insure simplicity and durability of construction, as

well as compactness, efficiency, andpracticability.

With this object in View my invention consists of a mechanical movement embodying novel features of construction and combinations of parts substantially as disclosed herein. 7

Figure 1 represents a top plan view of my mechanical movement. Fig. 2 represents a vertical central sectional view with the actuating mechanism in elevation and shown at its highest point when in action. Fig. 3 represents a transverse sectional view with the shaft-actuating mechanism at its lowest point, and Fig. 4 represents a plan view of the driving-gear and the peculiar mutilated or part gear used in my mechanism.

Referring by letter to the drawings, the letter A designates the frame of my device, which consists of the supporting legs or standards B, the horizontal bearing-arm C, the lower circular closed frame-section D, having the shaft-bearing E and the surrounding horizontal track or way E, and the curved guideway F, and to the lower section is bolted or otherwise secured the upper frame-section Gr, having a similar track or horizontal guideway H and the curved guideway J, which, with the guideway F and track or way E, forms a continuous track or guide around the frame of the device. The frame is further formed with the countersunk or depressed portion K on one side, and the upper part of the frame is formed with the yoke or bail L, having a shaft-bearing M.

Mounted in the bearing-arm of the frame is the horizontal driving-shaft M, which carries at its inner end the driving-pinion O, which meshes with the series of teeth or projections P on the segmental hub or rim Q, which hub or rim is integral with the sleeve R, mounted rigidly upon the shaft S, which is arranged in the bearings of the frame and, as usual, carries at its lower end an agitator or suitable device. (Not shown.)

Extending from the smooth face of the hub or rim is the single centrally-disposed long arm T, which carries a roller U, which roller travels in the continuous guideway or track formed in the upper and lower interior sections of the frame.

The segmental or part hub may have the teeth provided with antifriction-rollers, or they may be solid teeth, as the invention would operate efficiently either with or without such rollers. It will also be observed that the curved faces of the track or way are arranged on each side of the driving-pinion and that a continuous and unbroken track is provided for the end of the long arm, with its roller, to travel in.

From the foregoing description, taken in connection with the drawings, the operation of my mechanical movement will be readily understood, and I will simply state that motion is imparted to the horizontal driving-shaft and from thence to the driving-pinion carried thereby, which in turn meshes with the teeth or projections on the segmental hub, and the end of the long arm travels in the horizontal and vertically-disposed curved guideway, and that the shaft is given a half-turnand a rising action in one direction and a half-turn and falling action in the opposite direction, the teeth of projections of the hub being at all times in engagement with the driving-pinion and the end of the long arm, with its roller,

traveling in the horizontal portion of the track or channel until it reaches the curved guide or track, then switching off into the other horizontal portion of the track. In other words,

the frame provides a pair of horizontal tracks connected by the two curved stop faces and the arm at its highest point travels in the upper horizontal track and at its lower point travels in the lower horizontal track, said arm engaging first one curved face or guideway and then the other, thus effecting the reciproeating and the vertical or rising and falling action of the vertical shaft, as will be apparent.

It will be understood that it is absolutely impossible for the movement to fail in its operation or action, as the continuous track insures the proper engagement of the drivingpinion with the teeth of the segmental hub, and also that the arm travels in the continuous horizontal tracks and the curved guideways and that such construction insures a smooth and easy running of the parts and produces a simple, durable, inexpensive, and thoroughly practical mechanism.

I claim- 1. In a mechanical movement, the combination of a horizontal driving-shaft, a drivingpinion, a hub carrying a series of teeth meshing with said pinion, an arm extending away from said hub, a shaft on which said hub is mounted, and a continuous track in which said arm alone travels.

2. The combination of a frame having a horizontal shaft-bearing portion and a closed frame provided with a pair of parallel tracks merging into a pair of curved guideways, a vertical shaft mounted in the closed frame, a hub or part wheel mounted on said shaft and having on one side a series of teeth, a drivingshaft carrying a pinion meshing with said teeth, an arm extending from said hub or part wheel and having its end traveling in said parallel tracks and curved ways.

3. In a mechanical movement-the combination with the driving means, the vertical shaft, a hub on said shaft having an arm or extension, and a continuous track or Way in which said arm alone travels.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES WV. MARTIN.
