12 claims. (ci. "J4-fzs) Our invention relates to improvements in drivingj gears.

'The objects of our invention are:

To provide a. driving gear which will revolve two shafts simultaneously, one of said sha'fts having a continuous uniform rotary movement and the other shaft having a rapid reciprocating rotary movement combined with a slow, Substantially continuous progressive rotary movement in one ection of reciprocation; to provide-simple means by which the rotating dolly of a reciprocating washing machine can be given a progressive forward movement simultaneously with its reciprocating movement; to provide means for rotating a shaft progressively forward and simultaneously reciprocating the shaft; to

provide a combined wormand worm-gear operable simultaneously as a worm-gear andJack and pinion, with means for\,siniltaneously rotating -20 and reciprocating the wdrm.

We accomplish these objects by the means illustrated in the accompanying drawing, in which,-

Figure 1 shows a longitudinal section of our 25 gear on the line I-I of Figure 2;

Figure v2 shows a sectional elevation of our gear on the line 2.-2 of Figure 1;

Figure 3 is a cross-sectional detail on the line 3 3 of Figure 2;

30j Figure 4 is a sectional detail of the brace, 2|,

on the line 4 4 of Figure 1.

Similar numerals throughout the several views.

Our apparatus comprises a housing, I, which 35 may be of cast-iron orother suitable material and 'which may be united to a rigid base or cover plate, 2, in any desired manner.

Integral with the main housing, I, we form a housing, la, forthe drive-shaft, 3, and worm, l,

,40 with suitable bearings, sa, formed therein, for the motor-shaft, 3, on one en d of which the'worm, l, is formed or splined orotherwise suitably secured.`

The worm, 4, meshes with and drives the wormgear-wheel, 5, which is secured upon the lower end of the shaft, 6. The shaft, B, may be utilized to drive a wringer or other-apparatus.

A hub, 2b, is formed integral with the cover 50 plate, 2, 'which contains bearings, 1 an'd B, in

which the shaft, 6, revolves.

The wheel, 5, has' suitably secured thereto or formed integral therewith, a bevel-gear-wheel,`9. A crank-pin, I3, is rigidly secured to the wheel, 5, 55 concentricall'y with the bevel-gear, '9, through n forms a yoke, the two arms of which refer to 'similar parts which it passes, and may be secured therein in:

any desired manner.

A rotatable shaft, I I, has one end revolvably mounted in one end of the bearing-block, I2, the other end of which forms a socket or bearing, I 2a, which embraces the crank-pin, I3, while the intermediate portion, I2b, of the bearing-block, I2,

opposite sides of the bevel-pinion, III.

Upon the end of the shaft, ,I I, which acts as a connecting-rod, I mount a bevel-pinion, III, which is rigidly secured to the shaft, II, and meshes with thebevel-gear, 9.

'I'he opposite end of the shaft, I I, has a worm, Il, formed thereon, which meshes with and actuates they wtorm-gear, IB, rigidly-mounted upon the shaft, Il, f

'I'he shaft, Il, is splined or otherwise keyed to the wheel; I6, and the lower end of the shaft, jl, is mounted yin a bearing, I5, preferably formed in tegral with the housing, I. An additional bearing, Il, is formed integral with the base or cover plate, 2, and forms an upper bearing for the shaft; Il, above the base or cover plate.

The upper end of the shaft, Il, may be united in any desired manner to the lower end of any machine which it is desired to actuate thereby,

such as the dolly of a washing machine.

The worm, I1, is held in mesh with the gear,

I 9, by a sleeve, I9, in which it is slidingly andV revolvably mounted. The sleeve, I9, hasa lateral extension formed thereon, which is formed integral with a collar, I9a, which is pivotally mounted upon the shaft, Il, above the gearwheel, I6. The sleeve, I9, is thus free to rock upon the shaft, I4, as a pivot.

'Supports or braces, 20 and 2l, may be formed integral with the base or cover plate, 2, by which the base"plate, 2, can be rigidly secured to the body of any apparatus which it is desired to operate, such as a washing machine body. l

The hub, 2a, may be threaded internally at its upper end to permit it to be rigidly secured to the bottom of a washing machine 'tub or to any other object to which it is desiredto attach it by any suitable form of coupling.

Inthe operation of my machine, the motor or other prime-mover upon the shaft, 3, may be started, causingthe shaft, 3, to revolve in either direction' desired. As the shaft, 3,'revo1ves, the worm, l, will drive the worm-gear-wheel, 5. As the w eel, 5. revolves, it will carry the crankpin, I and the fixed bevel-gear', 9, around in a circle.

As the gear, 5 revolves, the gear-wheel,` 9.'

- gear, 5, may be varied by changing the relative diameters of the bevel-gears, 9 and III, and the length of travelof the gear, 9.

At the same time that the gear, 9, is rotating the gear, IIJ, the crank-pin, I3, will be carrying the head, IZa, of the block, I 2, around in al circle,

which willcause the worm, I1, to slide backward' and forward in the sleeve, I9, and the worm, I1, will act as a rack to reciprocate the worm-gear, I6, which will act as a pinion. In the meantime, the sleeve. I9, will rock upon its` pivot, I4, so as to accommodate the variation in angle caused by the different positions of the crank-pin, I3, and connecting-rod, II.

When the ratio of the bevel-gear, 9, and bevelgear, I0, is two to one, .the shaft, II, will be given two complete rotations with each rotation ofthe shaft, 6, and the gear, l6, will accordingly travel a distance equal to two spaces upon the worm, I1, in addition to the forward and backward movement caused by therack and pinion action described.

It will thus be seen that with each reciprocation of the gear, I 6, it will be advanced the distance occupied by two ofvits teeth and in case of a washing machine, a dolly attached to the shaft, I4, will be proportionately advanced.

This action may be utilized and will be valuable in various types of machines, but has a particular value in the case of washing machines because of the tendency of the clothes to pack and tear when the reciprocatory motion of the dolly is uniform. The effect of this progressive movement of the dolly which may be caused by our apparatus, will be to loosen up the-clothes when hunched and to prevent the packing thereof in-` side of the washing machine.

Our apparatus will also tend to prevent rolling the clothes in a machine in a ball, and will aid in keeping them separated so as to improve the washing action thereof.

, It should be noted that whilewe have shown the drive-wheel, 5, and the driven wheel, IB, as lying in the same plane, and the shafts, 6 and I4, as being'parallel, this arrangement is not necessary, but our apparatus will permit a large variation in relative angle of these wheels and shafts so long as the axes of the shafts are kept at right angles to the longitudinal axis of the connectingrod, II. v y

We do not limit our claims to the precise forms shown in the drawing, as it is obvious that vari-- ous modifications may be made without departying from the spirit of our invention, and our apparatus may be applied to various types of machines in cases where a progressive rotary action is desired in connection with :a reciprocatory action.

Our apparatus is designed to be operated preferably by a reversible electric`v motor, but the shaft, 3', may be driven by any desired form of prime-mover and we do not limit our claims to an electrically driven machine.
