KARL SANDERS, 'OF RUGBY, NORTH DAKOTA.
ALTERNATING ROTARY GEARING.
Specification of Letters Patent.
Patented 'Sept.'26, 1916.
Application filed. May 3, 1915. Serial No. 25,398.
T 0 all whom it may concern:
Be it known that I, KARL SANDERS, a citizen of the United States, residing at Rugby, in the county of Pierce and State of North Dakota, have invented certain new and useful Improvements in Alternating Rotary Gearing, of which the following is a specification.
This invention relates to washing machines, and particularly to the class that comprises a horizontally disposed reciprocating cylinder.
The object of my invention is to produce means by which the cylinder may be rotated in a given direction for a certain number of revolutions, then a reverse motion for approximately the same number of revolutions, both directions being obtained from a shaft that is constantly driven in one direction and which forms a part of the washing machine mechanism.
In producing my machine I have provided for the motions referred to above, employing fewer parts than any machine on the market of which I am aware, and one of the objects of my invention is to do this character of work with a device constructed of very few parts.
In the drawings forming part of this specification: Figure 1 is an end elevation of a washing machine with my invention applied thereto. Fig. 2 is a plan view of the mechanism shown in Fig. 1. Fig. 3 is a transverse sectional view through the cylinder of the washing machine. Fig. 4 is an end elevation with part of the frame and the worm gear removed. Fig. 5 is a detail view of the rocking lever, and Fig. 6 is a detail view of the worm gear showing its operating cam.
Like characters of reference designate corresponding parts in the several figures of the drawings.
In the drawings I have shown the outside cylinder 1 and the inside cylinder 2 of an ordinary washing machine, the same being mounted upon a frame 3, said frame being extended at one end to form a rectangular support for my gearing mechanism. The inner drum 2 is mounted upon pintles in the ends of the outer drum, one of said pintles being extended and having mounted thereon a large bevel gear 5. Meshing with the gear 5 are bevel pinions 6 and 7, each of which is feathered at 8 upon a shaft 9 suitably mounted in bearings secured to the frame 4:. The sha t 9 is designed to be constantly driven in a given direction and is provided with a pulley 10 which may be any of the ordinary jaw clutch type and to which any suitable belting may be applied. The shaft 9 has secured near its central portion a worm 11, said worm engaging a worm gear 12 provided witha cam block 14 designed to move a rocking lever 15 upon its pivot 16 secured to the frame 4. The lever 15 is provided with an opening 17, the sides of which are formed into cam surfaces 18-, said cam surfaces designed to be alternately engaged by the cam block 14 on the gear 12 during the course of its rotation. The rocking lever 15, has secured thereto pins 19 which engage the vertical slots 20 in the ends of reciprocating bars designed to slide in suitable guides mounted upon the frame 4:. The reciprocating bars 21 have adjustably secured to them adjacent their outer ends yokes 22, said yokes fitting into grooves 23 in the hubs of the pinions 6 and 7. The frame 4: is provided with bearings 24 which embrace the shaft 9 on each side of the worm 11, thereby positively preventing any longitudinal movement of the worm 11 with respect to the frame 4 upon which the gear 12 and the rocking lever 15 are pivoted. The fact that the cams 18 on either side of the rocking lever 15 are exactly alike insures the rotation of the drum 2 a given number of times in either direction, due to the shifting of the bevel pinions 6 and 7 through the instrumentality of the rocking lever 15 and the slide bars 21.
The operation of my device is as follows:
The shaft 9 being constantly driven inone direction and the bevel pinion 7 engaging the gear 5, as shown in Fig. 1, will drive the washing machine cylinder in a given direction. During this operation the gear 12 is being constantly rotated by the worm 11 and its cam block will swing around and operate against the lever 15 until said lever assumes the position shown in Fig. 4 of the drawings, when the pinion 7 will have become disengaged and the pinion 6 engaged with the gear 5, thereby rotating the washing machine cylinder in an opposite direction to the one it would rotate in when the parts are as shown in Fig. 1 of the drawnumerous slight modifications without d6- parting from the spirit of my invention or the scopeof the claims.
ing designed to mesh With pinions feathered upon a constantly rotating shaft, a rocking lever provided With adjustable rods for shifting said pinions and means carried by .the shaft for rocking said lever.
- 2. A device for imparting alternating rotary motion, comprlsing a bevel gear attached to the rotating member, said gear 5 being designed to mesh With pinions feathered upon a constantly rotating shaft, a rocking. lever provided With adjustable rods for shifting said pinions, said lever beingactuated by a cam driven by a Worm on the constantly rotating shaft.
