GEARING FOR LAUNDRY MACHINERY.

Specification of Letters Patent.

Patented May '7, 1912.

To all whom it may concern:

Be it known that we, ANDREW TENSEN and FRANK VoNoRAsnK, citizens of the United States, residing at Chicago, in

the county of Cook and State of Illinois,

have invented new and useful Improvements in Gearin for Laundry Machinery, of

which the following is a specification.

This invention relates to gearing for laundry machinery, of that class employing a stirrer for agitating the clothes within a tub, and having a fly wheel for facilitating the work. I

One of the objects of this invention is to provide operative connections, between the stirrer shaft and a fly wheel located underneath the tub, havin a construction whereby the lid of the tub may be raised withoutdisturbing any of the elements of said connections, and in which the'lid may be raised from its closed position regardless of the position of the elements comprising the operative connections.

Another object is to provide gearing between the stirrer shaft and a motor driven fly wheel located underneath the tub whereby the mechanism may be driven by power or by hand as desired.

Another object is to provide operative connections between such gearing and an auxiliary laundry device carried by the-tub,

as for instance a'wringer, mangle orthe like.-

Other objects and advantages will appear in the course of this specification and to such ends this invention consists in the several novel features of construction and arrangement set forth in the following specification and particularly pointed out in the claims ;v e

In the drawings furnished herewith, Fig- 40 me 1 is aside elevation of mechanism embodying the present improvement ina washing machine and wringer, Fig. 2 is a view partly in plan and partly in horizontal section, the line of section being indicated at 2-2 Fig. 1, and Fig. 3 is a plan of the upper elements of the gearing andv a fragment of the lid, and wringer.

Referring to said drawings 10, represents a tub carried by legs 11, and having a lid 12, hinged to the top of the tub and locked B. Cnnrs thereto in accordance with the common practice, A vertical stirrer shaft 13,.carrymg a stirrer 14, is journaled in a frame 15, on the lid and projects down into the inter1or of the tub as is customary The frame 15, is secured to the lid of the tub and has two upwardly extending brackets in which is journaled a rock shaft 16, that carries upon its inner end a bevel pinion 17 meshing with a bevel pinion 18, secured to the top of the stirrer shaft 13. Mechanism is provided for rocking the rock shaft 16, one form of mechanism comprising; as shown, a rocker member 19, havinga gear segment 20, that meshes with a inion 21, fast upon the outer end of the roc shaft 16. It is obvious that by rocking the rocker member a rotary reciprocal movement is imparted to the stirrer shaft. Said rocker member 19, is fulcrumed upon a frame 22, secured to the side of the tub, and if desired, may be formed with a handle socket 23, arranged to receive a handle 24, by means of which the rocker member may be worked by hand. To facilitate the work, a fly wheel 34, is provided, and between said rocker member and fly wheel are operative connections, including speed increasing gearing, whereby the movements of the rocker member may be transformed into a continuous rotary movement of the fly wheel at a comparatively high rate of speed. The particular form of operative connections shown between the rocker member and fly wheel will now be described. A bevel gear wheel 26, carried by a shaft 27, journaled in a bracket 22*, of the frame 22, is connected to the rockermember 19, by a link 28, as shown, whereby the rocking motion of the rocker member may be transformed into a continuous rotary movement of the bevel gear wheel 26, and reversely the rotary motion of the bevel gear wheel may be transformed into a. rocking motion of the rocker member. Said bevel gear wheel 26, meshes with a bevel pinion 29, fast uponthe upper end of a ver-.

tical, rotary shaft 30, ournaled in

brackets

31, 32, formed upon t e frames 22, 33, respectively. The frame 33, is located below the tub and is secured to the legs 11, thereof.

The fly wheel 34, is journaled upon the .underside of the frame 33, and is operatively connected with the rotary shaft 30, by mechanism here shown as comprising a small belt pulley 35, secured upon the shaft '36, of the fly wheel 34, a larger belt pulley 37 fast uponv the rotary shaft 30, and a belt 38, trained around said pulleys. For convenience, construction and arrangement, we

have placed the frame 33, between the pulley 35, and fly wheel 34, said pulley resting upon the frame and supporting the fly wheel therebelow.

In the operation of the machine thus far described, the rocker member 19 is rocked back and forthby hand, whereby a rotary reciprocal movement is imparted to the stirrer shaft and a continuous rotary movementis imparted to the bevel gear wheel 20 rotary shaft 30, at a comparatively high 26; said bevel gear wheel in turn drives the rate of speed, by reason of the difference in size between the bevel gear wheel and pinion, and the rotary shaft 30, drives the fly wheel 34, at a high rate of speed, whereby energymay be stored up by reason of the momentum of the "flywheel, and said energy,

utilized until spent, in operating the stirrer shaft. l

Power mechanism is provided fordriving the gearing and as 'shown one form of power mechanism comprises an electric motor 39, secured tothe underside of the.

turn, will betransmitted to the stirrer shaft,

through the instrumentality of the vertical rotary shaft 30, the connections between the fly wheel and said shaft 30, and the connections between said shaft and the stirrer shaft. The mechanism heretofore referred to as the speed increasing gearing now becomes a speed decreasing gearing and said I gearing will be hereafter termed as speed converting gearing.

An auxiliary device 41, such as a wringer, mangle or the like, is carried by the tub 10, and may be operatively connected to the gearing of the washing machine. As shown in a companion application for gearing for laundry machinery, Serial Number 621,734, filed on even date herewith, the shaft 27, of the gear wheel 26, bears a pinion 42, that meshes with one of a pair of

pinions

43, 44, carried by a shift lever 45, either of said pair being arranged to be brought into mesh with a pinion 46, fast upon one of the wringer roll shafts. The construction and operation of this feature of the device is fully set forth in our companion application and requires no further description herein.

It is to be observed that the lid and gear mechanism carried thereby maybe raised without disturbing the remainder of the gearing. The fly wheel and part of the operatin mechanism, including the motor, is locate under the tub and out of the way. Other advantages are readily apparent from the above description.

We realize that various alterations and modifications of this device are possible, without departing from the spirit of our invention, and we do not therefore desire to limit ourselves to the exact form of construction shown and described.
