WASHING MACHINE.

Application filed February 16, 1920. Serial No. 358,834.

To all whom it may concern:

Be it known that I, HERMAN/C. DOMAN, a citizen of the United States, residing at Oshkosh, in the county of l/Vinnebago and State of Wisconsin, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

This invention relates to washing machines for operating upon clothes, fabrics, etc., and more particularly to machines of the type wherein the'washing action is produced by the reciprocation of a vacuum cup, sometimes termed a pounder.

It has been my aim in this invention to effect certain improvements in the driving mechanism by which rotary movements of a driving shaft are converted into oscillatory and reciprocal movements of a pounder shaft. The invention consists in the features of construction and combinations of parts which will fully hereinafter appear from the specification and claims, and from the accompanying drawing in which is illustrated an embodiment of this invention in the manner following: 7

Figure 1 exhibits partly in plan and partly in section on line 1-1 of Fig. 2 a driving mechanism which may conveniently be positioned upon the upper side of a cabinet machine; 1

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, showing certain of the parts in elevation and others in section;

Fig. 3 is an enlarged detail in transverse section taken on line 33 ofFig. 2;

Fig. 4: is an endview of the rod which controls the clutch; and v Fig. 5 is a detail thereof in elevation.

The washing machine is preferably con tained within a cabinet having a top 14 provided with a hinged cover 62 which overlies a tank within which is a vacuum cup mounted upon the lower end of a Work shaft 81. v i

i From a power source (not shown) means are provided for rotating a shaft 35 which extends above the cabinet within a framework whose baseis mounted thereon, as shown in Figs. 1 and 2. This frame is formed to provide a bearing 51 within which the upper end of the shaft 35 is journaled, a beveled gear 52 being mounted upon its extremity in mesh with a second gear 53 that is shiftably mounted upon a stub shaft 54 that is journaled within a bearing 55 formed on the frame 50. At the endof the shaft 54 which is opposite the gear 53 I have provided a clutch member 56 within which is a socket 57 of polygonal cross-section adapted to receive a clutch head 58 of similar formation which is carried fast on a crank shaft 59 from which projects a crank arm 60. The crank shaft is suitably journaled within a framework 61 having a base that is secured to the cover 62 which may be swung upwardly whenever required to afford access to the interior of the tank. The purpose of the clutch members 56 and 58 is, therefore, to establish or disestablish a driving connection between the two shafts 54: and 59 according as it may be desired to operate the washing mechanism or to open up the central cover to gain access to the tank within the cabinet.

In order that the socket member 56 may be moved into and out of clutching relation with the head 58, use is made of a spline 65 that is keyed within the shaft 54 and extended within the beveled gear 53 by which means the gear may drive the shaft, this connection, however, permitting the shaft to be shifted longitudinally within its bearing without affecting the gear 53. Such shifting movements, which in nowise affect the driving connection between the gears 52 and 53, may be accomplished through the medium of a grooved collar 66 which is made fast to the shaft 54; a rod 67 on which is eccentrically mounted a pin 68 that is disposed within the groove 69 of said collar;

and a bearing 70 in which said rod is journaled, the bearing being formed on a guard 71 that is carried upon the framework 50.

This guard overlies the moving parts of the mechanism that are mounted on the cabinet top, and is preferably formed interiorly with a depending web 72 having a groove 73 adapted to receive a tongue 74- that upstands from the top of the frame 50 in such a manner as to center the guard fixedly in place. A bolt 75 is entered through the guard to thread within a socket formed in the frame so as to lock the one part on the other. In order that the'rod 67 may be rotated to shift the stub shaft 54 and thereby clutch or unclutch with the crank shaft 59, an operating handle 76 may be provided as shown. By some means as this, the rod is turned within its bearing 70 to effect through the medium of the pin 68 and collar 66 a longitudinal shift of the shaft 54: toward or from the head 58 so as to establish or disestablish clutching relation between the shafts 54 and 59.

The means for converting rotary movements of the crank shaft 59 into a combined reciprocating and oscillating movement for the vacuum cup or pounder includes parts as follows: A suitable work shaft 81 is journaled within a bearing 82 formed in the base of the framework 61 near one end thereof, and carries at its lower end a vacuum cup or pounder ,(not shown). Extending upwardly from this base on opposite sides of the work shaft are two guide rods 83 on which is slidably mounted a cross head 84 that carries a collar 85. This collar is so mounted in place as to have capacity for turning, but may not move otherwise, and is adapted to receive the upper end of the work shaft to which it is made fast as by means of an arm 86 that extends both through the collar and shaft and laterally toward the crank arm 60. The end of this arm 86that is proximate to the crank arm 60 is formed to present in effect a ball 87 that is received within a cylindrical aperture 88 located near the swinging end of the crank arm. According to this construction, rotary movements of the shaft 59 produce through the driving connection between the crank 60 and arm 86 a combined oscillatory and reciprocating movement of the work shaft 81 to operate the pounder in a very effective manner upon the clothes contained within the tank. The ball and socket connection between the arm 86 and crank 60 is very advantageous in that it may be cheaply made, and may be put together with a minimum of effort. A guard 89 may be arranged upon the swinging cover over the operating parts thereon to safeguard against injury.

Manifestly the construction that I have shown and described may be modified or altered within certain limits without sacrifice of the improved features that are novel to this invention, and accordingly it should be understood that the protection accorded under this patent is to include all such modified constructions as fall within the purview of the claims hereto appended.
