DRIVING. MECHANISM.

Specification of Letters Patent. Application filed KarelilB, 1908. Serial No. 420,964.

Patented May 1 1, 1909;.

all whom it may concern: I Be it known that I, OLIVER B. WooDRoW, a citizen of the United States, residing at Newton, in the county of 'Jasper and State of Iowa, have invented a new and useful .Driving Mechanism, of which the following is a f specification.

' The object of my invention is to provide .means of simple, durable and inexpensive construction, permanently connectedto the frame 'of a washing machine, whereby all of' the operating mechanism, including an electric motor. or other suitable power device, may be mounted beneath the body of a washing machine in such a .manner as toybalance the weight of the washing, machine, and to be contained within the same amount of floor space vas..t.he washing machine of itself would occupy, and further, to. rovide operating means of this kind whereby the operator may readily and easily control the move- .ment of either the washing machine or wringer, so that either may be stopped or started instantly, whenever desired, and so I have used the reference numera that either the wringer or washing machine may be operated or both thrown out of gear, but only one at a time may be operated.

My invention consists in the construction, arrangement and combination of the VaI1011S- parts of the device, whereby the. objects contemplated are attained, .as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in

which-- Figure 1 shows a side elevation of the com.- plete device embod ing my invention. Fig. 2 shows a detail p an view. illustrating Ithe 1g. 3 showsa rear end elevation of the entire device embodying my invention. Fig. 4 shows an enlarged detail sectional View of'the clutch device, and-Fig. 5. shows a detail view. of thelower end of the lever for oper-.

ating the movable sleeve of the clutch device.

Referring to the accompanyi cate the washing machine body supported upon the legs 11. J Mounted in the-cover of the body is an agitator shaft 12, provided with a pinion 13.

At the front of the washing machine body is. a bracket 14, to whichan operating lever 15 is fulcru ned. This operatinglever haspivoted to its top arack bar 16 immesliwith;

drawings,

construction is attached. This wringer IS. provided with a grooved pulley 20 attached to one of the roller shafts.

Mounted beneath the body 10, and be tween the supporting'legs 11, is a platform 21, and supported'upon this platform is an electric motor- 22, or other suitable power de? vice. Fixed to the shaft of the motor 221s. a small pulley 23.

Mountedin bearings 24 below the body 10., is ashaft 25 having fixed to one endthereof a large pulley 26, which pulley is connected by'means of the belt 27 with the small pulley 23 .on the motor. Rotatably mounted upon the shaft 25 is a small pinion 28 having a ratchet clutchjinember 29 connected. there: with. Fixed to the other end of the shaft 25 is a sleeve 3 0"having thereon a small pulley 31 connected by a belt 32 with the pulley 20. Said sleeve is also provided Witha* ratchet clutch member 33. Slidingly mounted upon the shaft 25 between said clutch members 29 and 33, is a sleeve 34 having an annular groove 35 formed thereon.

'This sleeve is provided with a longitudinal slot 36, and a screw 37 is passed through said slot and seated in the shaft 25, to thereby permit the sleeve to move longitudinally upon-the shaft, and to revent its rotation thereon. On one end 0 the sleeve 34 is a ratchet clutch member 38, to co-act with the clutch member 29, and on its other end is a ratchet clutch member 39 to oo-act with the clutch member 33.

Mounted beneath the body 10 is a lever 40 having a fork 41 at its lower end to enter the groove 35.. This lever has a pitman 42 pivoted to itscentral portion, the outer end of. the pitrnan being pivoted to a lever 43, which lever is. fulcrumed to the bracket 44, and is. provided at its upper end with a lug. 45. desi ed'to enter thejnotchesefi in the curved racket 47', said lug beingyieldingly held in one of the notches 46 in which it may berplaced, by. the resiliency of the lever 43.

Thearran ement of these partsis such that when; the. ever 43 is in the position shown in Eig. 3,, then the sleeve 34 is held mid way between the ratchet members 29 and 33, and when the lever 43 is moved. to one.

side of its central position, the clutches 38 and 29 will enga e, and when moved toits other limit, the c utches 39 and 33 will ena 5 Mounted beneath the machine body is a large inion 48' having the pitman 17 pivoted to it, and arranged in mesh with the small pinion 28, so that when said small pinion is rotated, the rack bar 16 will be reciprocated and an alternating rotary motion will be imparted to the agitator shaft. In practical operation, and assuming that the motor is running, and assuming further that the sleeve 34 is in its central position, then neither the agitator nor the wringer are beingoperated. If it is desired to operate the agitator, then the operator grasps the lever 43 and moves its upper end away from the body 10, thus throwing the clutch members 28 and 29 into engagement. This will cause the small pinion 28 to be rotated with the shaft 25, and thereby o erate the large pinion 48, the pitman 17, t e lever 15, the rack bar 16, and the pinion 13 on the agitator shaft. stop the movement of the agitator, the lever 43 is returned to its central position, and if it is desired to operate the wringer, the.

upper .end of the lever 43 is moved toward 30 the body 10, thus throwing the clutch members 33 and 39 into engagement.

In a device of this kind, and especially in connection with the 'operation of a wringer, it is desirable to rovide means whereby 35 the operating devices may be instantly stopped. For instance, in regard to the wringer, and in the event that an article of clothing is being run'through. the wringer, and the article should become wound upon the rollers, or shouldbe'come entangled with other articles, then if the motion of the wringer was continued, either the article or the wringer might become damaged, and if, in order to stop the wringer it was necessary 4 to stop the motor and all the other machinery, then in many cases this could not be accomplished quickly enough to prevent damage. However, by means of my invention, either the wringer or the agitator may be thrown out of gear instantly, whenever the occasion demands, and on account of the friction which both the wrin er and the agitator are subjected to, they will instantly stop whenever the clutch device is moved to osition for throwing them out of gear.

aving thus described my invention, what I claim and desire to secure by Letters Patent, is
