WASHING MACHINE.

Application filed October 15, 1927. Serial No. 226,274.

- 10 like seal secured to the shaftand a portion of the tub in order to prevent leakage.

With the above and other objects in view,

my invention consists in the arrangement,

combination and construction of the various 15 parts of my improved device as described in.

the specification, claimed in my claims and shown in the accompanying drawings, in which;

Fig. 1 is a view partly in section and partly 2 in elevation of a washing machine embodying my invention.

Fig. 2 is a view taken on line 2-2 of Fig. 1.

Fig. 3 is a view taken on line 3--3 of Fig. 1.

I have shown a washing machine compris- 25 ing a tub 5 having an integral piece 6 forming a portion of the bottom thereo and a separate 1 1ece 7 secured to the piece 6 rivets 8 and orming the remainder of the ottom thereof. The piece 7 is somewhat drum shaped in 30 formation and is provided with a central apertured boss 9 in which is fitted a bushing 10 havin a flange 11 fitted on the top of the boss within the tub. Extended thru the bushing 10 is a shaft 12 which is provided 35 with helical grooves 13 at its top and is socured to a member 14 by a nut 15 at its bottom. A connecting rod 16 is secured to the clevis 17 and-pins 18 to the lower end of the member 14.

The connecting rod is secured at its lower end by a pin 19 to a worm gear 20, the connection being an eccentric one so that rotation of the gear will vertically reciprocate the rod. The car 20 is meshed with a worm 21 pro- 45 vide on the shaft 22 mounted in suitable bearings of the base 23. The shaft 22 is driven thru a universal joint 24 by an electric motor 25. The motor 25 is bolted to a base member 23 as at 27 and the washing machine 50 base member is likewise bolted as at 28 to the base 26.

The bushingdO is held in fixed position byt nut 29 on the threads 30 of screwing a 5 he bushing is provided with an the boss 9.

upward extension which encloses the helix ositive to prevent leak- 13 and a pair of keys 31 are inserted in the extension and mesh with the helical groove 13. Each of the keys 31 is split into two sections which may be separated by shims 32 in order that the length of the keys may be adjusted. After the length has been adjusted the keys are secured in lace by screwing a nut 33 into the upper en of the bushing 10. The nut ma beheld in fixed position by pins 34.

n agitator device comprisin a central portion 35 and blades 36 is provi ed, the central portion engaging around the upper portion of the bushing 10 and keyed thereto as at .37 so as to rotate therewith. The agitator is held in fixed vertical position by resting on the flange 38 provided on the bushing 10. i

A drain for the tub 5 is shown at 39 which dram may be opened and closedb means of a plug 40 on the end of a rod 41. he rod 41 1s connected at its outer end as at 42 to a throw prov1ded on the shaft 43 and operated by a handle 44.

A passage 45 connects the drain 39 with a space 46 which is provided between the bottom of the member 7 and flexible diaphragm like piece 47. The latter iece is secured at its outer ed es between t e bottom of the member 7 an the top of the base piece 23 by a plurality of setscrews 48. The the hragm is secured around. the shaft12 by acing its inner edge under the flange 58 of t e member 14 and screwing the nut 49011 the threads 50 and against the lower face of the inner periphery of the diaphragm.

The nut 49 may be locked in place by a pin or pins 51 extended thru openings therein into suitable aligned openings 52 in the member 14. Y Y

It will be readily apparent that rotation of the motor shaft 22 will cause reciprocation thru the connected parts of the shaft because of the connection of the keys 31 with the helix 13, will cause rotary reciprocation of the agitator blades 36. any water finds 12 and that reciprocation of the shaft 12, 1

drain 39. If an excessive amount of water should accumulate in the space 46 while the machine is in operation it may escape thru the opening 56 in the member 7 back into the tub. The opening 56 is normally maintained closed by a ball valve 53 seated therein and resiliently held by a spring finger 54 secured by a screw 55 to the bottom of the member 7.

It will be obvious that I have provided a machine which will successfully operate without leakage of water and which does not require expensive stufling boxes.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the splritof my invention and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.
