GEARING'.

ApplicationY led July 27,

To all whom t may concern:

Bc it known that I, WILLIAM H. SARGENT, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Gearing, of which the following is a specification.

This invention relates to gearings.

ln the embodiment illustrated the invention has special reference to gearings for operating washing machines, though it will be'understood that the use of the gearing is notl confined to washing'machines but may well be employed in any other embodiment in which the results or functions accomplished by the invention are desired.

An object of the invention is to provide a gearing comprising a drive shaft, a shaft to be driven mounted in a support which is movable relative to the drive shaft, and` gearing for driving the driven shaft. from the drive s haft in one position of said support, in combination with mechanism for preventing operation of the ldriven'shaft by the drive shaft when said support is in another position.

Another object of the invention is to provide a novel operating gearing for washing machines comprising a drive shaft, a driven shaft mounted in the movable lid or cover of the washing machine, a gearing for driving the driven shaft from the drive shaft when the lid or cover is in closed position,"

and means for rendering the gearing inoperative when the lid or cover is moved to open position so that the shaft supported by the lid or cover will not be operated when the lid or cover is out of'closed posi- `tion.

With the foregoing andy other objects in view, I have produced an eiiicient embodiment of the invention and have illustrated thesame in the accompanying drawings, in which Figure 1 is a plan view of my improved gearing applied to a. washing machine.

Fig. 2 is a side elevation.

Fig. 3 is a plan view of the gearing showing the clutch device released.

The present invention is shown in combination with a part of the gearing mech- :anism disclosed in my prior application Serial No. 52,615, filed September 25,1915.

As illustrated in the drawings the tub 1 constitutes a support for the -driving mech- Specification of Letters Patent.

anism and the lid or cover 2 constitutes a 'support for the driven mechanism.v

A frame including the vtwo arms 3 is secured tothe lid 2 lby bolts 4. The extremities of the arms 3 are provided with bearings 5 which are pivoted upon the drive shaft 6, the latter being journaled in bearings carried by the tub, one of which is shown at 6a. 3 are a part constitutes a hinge for the lid or cover, the shaft 6 being the pivot of the hinge. beveled pinion 7 is loosely mounti ed on the shaft 6 and meshes with a bevel pinion 8 supported on a shaft 9. The shaft 9 is at right angles to the shaft 6 and is` the bearing 12 and in abearing 14 whichjfs,

formed in a frame 15 secured to the liddr cover 2 of the Washing machine. A pinion 16 attached to the shaft 13meshes with a peripheral se lies of teeth 17 formed in connection with he pinion 8.

A vertical shaft 18 is -journaled in bearings in the frame 15 for axial and rocking movements. Axial movements are imparted to the shaft 18 by the rshaft 13 through a crank connection 19 which moves the shaft 18 axially in opposite directions when the shaft 13 is in rotation. Rocking movements are imparted to the shaft 18 by reciprocation of a rack 20 which meshes with a pinion 21 on the shaft 18. One end of said rack 20 is connected to a crank pin 22 extending from a pinion 23 revolubly supported upon an axial member 24 above the bearing 12. The pinion 23 is a beveled pi nion and is in mesh with a pinion 25 attached to the shaft 13 so that the pinion 23 will be constantly rotated and the shaft 18 will be given an alternating rotary movement by the constant rotation of the shaft 13 in one direction.

No claim is made herein to the specific construction of the rack 20 and pinion 21, nor. are said parts illustrated in complete detail in the accompanying drawing for the reason that they are clearly and fully shown and constitute 'a part of the subject-matter of my above-named application Serial No. 52,615

As previously stated, the pinion 7 is loose:l 4upon the shaft 6. For driving the pinion 7 by the shaft 6 a clutch device is provided which in one position locks the pinion-to the shaft and in another osition releases the pinion to enable the sha t to rotate witheut driving the pinion. This,clutch device .may assume any convenient form and, as

Y.illustrated comprises a sliding clutch member 26 feathered or splined upon the shaft 6, and adapted to engage a coperating clutch member 27 rigid with the pinion 7 The clutch member 26 is actuated to clutch engagement with the member 27 by a spring 28 encircling the shaft 6 between the clutch member 26 and the adjacent bearin 5.

' As a result ofthis construction t e pinion 7 is normally locked to the shaft 6, and the shaft 18 will ybe constantly operated when the shaft 6 'is in rotation. However,

it is desirable in washing machines to pro-v vide means for stopping ory preventing operation of the shaft 18 when the lid or cover is raised to openv position. Heretofore machines have been constructed with manually more or less serious injury. Therefore, it

is highly important that provision be made for automatically throwing the operating mechanism out of gear as an incident to opening of the lid or cover of the washing machine. 'This automatic mechanism# constitutes an essentialpart of my present invention, and I will;l now proceed to a description thereof. i

A clutch operating rod 29 is mounted for' axial and rocking movements in bearings 30 extending from the bearing'6a in which the drive shaft is journaled. The inner end of the rod 29 supports a collar 31 having two arms 32 extending into a Icireum-'v ferential groove 33 in the clutch member 26. Thus when the rod 29 is'moved axially in an outward direction the clutch member 26 is disengaged from the clutch member 27 and the springv28 is placed under compression. A cam 34 is formed on one of the bearings 30 and a matching cam 35 is connected to the rod 29. An arm 36, in connection with the rod 29, lconstitutes means for operating the cam 35 as required to move the rod 29v in order to disengage the clutch member 26 from the clutch member "Ll 27. The arm 36 bears against the lid. or

maar?? cover 2, and when the lid or cover is closed the two cam parts occupy the relative p0- sitions illustrated in Fig. 1, in which the two clutch members 26 and 27 are engaged. However, when the lid or cover is ralsed to open position the arm 36 is actuated and turns the cam 35 against the cam 34:, thus moving the rod 29 outwardly and disengaging the'clutch member 26 from the clutch member 27, as illustrated in F ig; 3. rThe cam members 34 andf35, however, do notl become locked in the position shown in Fig. 3, but permit the spring 28 to actuate the clutch member 26 into clutching engagement with the member 27 automatically as an incident to closing of the lid or cover 2. Thus no attention is required from the op erator to throw the operating mechanism' into or out of gear when the lid or cover erating mechanism 1s 1n no sense dependp ent upon.the specific form of gearing by which the shaft 18 is driven by the shaft 6.
