GEARING F03 'WASHING-MACHINESi.

ing machines of that class in which a part of the force or energy used to operate the heater is stored up in a fly wheel whereby the energy thusstored up may continue to operate the beater until exhausted, after the exertions of the operator have ceased.

The object of this invention is to simplify constructions of this class, and this I have accomplished by reducing the number of parts to a minimum, and connecting the power lever to the beater shaft without the interposition of other shafts.

Another object is to produce compactness and this is accomplished by arranging the parts close to the tub all of the operating parts with the exception of the flywheel lying substantially in a horizontal plane.

To such end the invention consists in certain novel features of construct-ion and ar rangement the description of which will be found in the following specification and the essential features of which will be definitely i so proportioned and arranged that the oscllpointed out. in the claims appended thereto.

The invention is clearly illustrated in the.

drawings accompanying this specification in which Figure 1 is a plan view of a structure embodying my invention. Fig. 2 is a front view thereof. Fig. a. perspective view of the oscillating operating lever. Fig. 4 is a side view of the device, the liy wheel be ing cut away on the line 4-4, Fig. 1. Fig.

is a central. vertical cross ection taken on the line 55, Fig: 1. Fig. 6 1s a plan view of the bracket or plate which supports the gearing, and Fig. 7 is a front view of a i slightly modified form of construction.

Referring to these drawings, 10 represents a tub or other receptacle in which are placed.

the clothes to be-washed. The upper end of i transferred to the fly wheel by means of the pitnian 51, bevel gear whereby when the exertions of the operator this tub is closed by a cover 11 which contains a lid 12, hinged thereto, by means of hinges l3 and adapted to he lockcddown upon the tub by means of. a hasp or other lock it. A. bracket or late is secured to the lid 19. by means or belts or screws 21,

and said bracket contains a downwardly extending sleeve 22 which is axially disposed with respect to the tub. A beater shaft is journaled in the'sleeve 22 and carries upon its lower'end a beater 31 which is vertically slidable thereon, the beater and beater shaft being of any familiar construction and requiring no specific description so far as this specification is concerned. The upper end of the beater shaft 30 bears a pinion 32 which meshes with an internal rack l1 formed upon the by means of a stud 2t and bearing aperture,

the stud projecting out from one memberv and turning in the bearing aperture in the other;.the forward end of the operating lever is formed with a socket 42 in which may be secured the handle 43. It is obvious that oscillation of the lever will cause a corresponding rotary reciprocating movement of v the beater shaft 30.

. The mechanism for storing up a part of the energy used in actuatmg the beater shaft will now be described. A bevel gear wheel 50 is jo'urnaled upon the bracket or frame 20 by means of a stud 23 and said bevel gear wheel 50 is connectedto the operating lever by means of a pitman or connecting rod 51 which is secured upon wrist pins Bil-4i, eXtendin-g up from the bevel gear wheel and operating lever respectively. The parts are lating movement of the operating lever is transformed into a continuous rotary movement of the bevel gear wheel. A bracket 60 is bolted or otherwise secured upon the tub and contains a radially extendare shown as secured upon their supports by means of cotter pins, although this form of f "connection 1s not material.

In operating the device the operating lever is oscillated across the top of the tub and the beater is thereby given a rotary rcc1proeating movement. Partof the energy thus used in operating the lever is however,

and bevel pinion 71,

have ceased, the momentum which has been stored up in the fly wheel will continue to operating lever 40. The said lever 40 is pivoted upon the bracket or plate 20" rotate the fly wheel and consequently operate 1 the beater shaft through its connections therewith. One of the advantages of this construction consists in the fact that the lid may be raised to expose the interior of the tub without necessarily carrying with it the heavy fly wheel, which as shown is journaled upon the stationary part of the tub.

In Fig. 7 the bracket-20, is shown as formed with an integral stud 60*, upon which the fly wheel 70 is journaled. In

some cases it may be found desirable to cast the bearings for all of the operating parts in one piece; and, in that case the fly wheel will be supported by the lid.

In experimenting with washing machines of this class I have found that the nearer the operating lever can be brought to the beater shaft, the easier it becomes to operate the lever, and besides this, there is less danger of breakage to the parts, caused by the strain which isput upon them in operating the lever. In this device the operating lever engages the'beater shaft directly through the pinion 82 and is connected to the fly wheel by the simplest form of gearing adapted to revolve the fly wheel at a high rate ofspeed. It is essential that the fly wheel be driven at a high rate of speed, otherwise its momentum will be insuflicient to be of much use in continuing the movement of the beater shaft after the exertions of the operator have ceased.

I claim as new and desire to secure by Let- Y te'rs Patent 1. In agearing for washing machines, the combination with a beater shaft and pinion, of an oscillatory. operating lever lying in the plane of said pinion and containing an integral internal rack, meshing with said bevel gear, and a pitman connect ing said lever with the bevel gear and adapt ed to transform the oscillatory movement of the lever into a continuous rotary movement ofthe fly wheel.

3. In a gearing for washing machines,
