To all whom it may concern:

Be it known that I, HORACE CAMMACK, a citizen of the United States, residing in Des. Moines, in the county of Polk and State of Iowa, have invented certain new and useful I Improvements in Gearing for VVashing-Machines, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings, forming part of this specification. My invention relates to a gearing for operating the agitators of washing machines, andit has for its object to provide a simple and eflicient construction of this character and one which includes a rack member for imparting rotary motion to the agitator, and means whereby the operation of said rack' member is governed in a manner to cause it to constantly 'operate with uniform action with a slight expenditure of power in its operation.

Figure I isa top or plan view of my gearing. Fig-II is a side elevation of the gear- 1 ing. Fig. III is a top or plan view of a modification. Fig. IV is a top or plan view of another modification. Fig. V shows a detail viewillustrating the swivel joint for. connecting the rack with the pitmen in the modified form shown in-Figs. III and IV.

1 designates part of a washing machine, which may be of any ordinary construction and which may support or have incorporated therein a tub to receive the clothes to be washed by the agitator and gearing to be described. .7 p 2 is an agitator which is adapted to oper'ate in the tub of the machine and which may be of any desired form or construction.

The agitator iscarried by a spindle-3 which is mounted in a bearing post and has a pinion 5 fixed thereto. The bearing post 4: is rigidly mounted upon the top of the washing machine to which it is secured in any suitable manner.

I "6 designates a reciprocatory rack bar arranged in mesh with the pinion 5 and held in such position by stationary keeper arms 7.

9 is a hand lever to which the rack bar is pivoted at 8- and which is in turn pivoted at 10 toa bracket arm' ll-that is fixed to a stationary part of 'the'machine. The hand lever is supported by the bracket arm to.

- which it is p voted and it'serves as an operv.ating. member for the reciprocatory rack bar whereby said rack bar may be moved to and fro to mpart rotary motion to the agitator 2 due to the meshing of said rack bar with the pinion 5 on said'spindle.

12 designates a bearing frame that is attached to the top of the washing machine. This frame is provided with a pair of guides 13 between which the rack bar is adapted to operate and it is also provided with bearings 14 and 15 arranged in aliirementwith each other and occupying positions at right angles to the rack bar 6. The frame 12 also hasabearing arm 16' projecting outwardly therefrom and terminating :in a bearing 17.

18 is a. governor wheel journaled to the bearing 17 and provided with a, wrist pin 19. 20 is a pitman loosely fitted at one end to said governor wheel wrist pin and pivoted at its otherend tot-he rack bar 6 .at 21.

22 is a pinion-that is arranged in mesh with the governor wheel and which is car-- riedby a fly wheel shaft 23 thatis supported by the bearings 14 and 15 and has fixed thereto a fly wheel 24.

In the practical use of my gearing the operation is as follows: The operator grasps the hand lever 9 and by rocking it to and fro imparts a reciprocatory movement to the rack bar 6 and said rack bar by meshing with the pinion 5 serves to impart a rotary motion to the agitator 2. During the reciproeation of the rack bar thepitman 20 is moued longitudinally to and fro and by reason of its pivotal connection with the rack bar and the governor wheel it serves to impart rotation to the governor wheel. rotary motion of this wheel is transmitted-to the pinion 22 and the pinion in turn serves to drive the shaft 23 and the fly wheel 24 fixed to said shaft. It will be seen that by this arrangement of the governor wheel and The 1' the fly wheel operatively connected with each other, and the governor wheel being connected to the reciprocatory rackbar by the.

pitman 20, said fly wheel and governor wheel are caused to control the movement of the rack bar whereby it will reciprocate with an even and regular motion and with a slight expenditure of power after the gearing is once placed in motion.

In the modification illustrated in Fig. III,

the pinion of the'agitator spindle is operated by a segmental rack 6 which is carried by a swinging armfiV-that is pivoted atits'end farthest from the rack'at 28. The swinging arm is vibrated through the medium of a connecting rod 29 that is united to the rackarm 6 by a swivel 30 and attached to the hand lever 9 by a coupling member 31. The

pitman 20 is connected to the swivel 30 and is attached to the governor wheel 18' by a swivel wrist pin 19. The parts illustrated in Fig. III are adaptedto have associated therewith the fly wheel, its shaft and pinion which operate in connection with this modification in the same manner as previously described with respect to the main form of caring.

The modification shown in Fig. IV difiers from the modification shown in Fig. HI only in the respect that the pivotal point of the vibratory rack bar arm 6 is located in termediate of the ends of the arm instead of at its end, and the connections leading to said arm are united thereto at its end far-' thest removed irom the rack 6 instead oi at the end at which the rack is located.

One of the advantages of having. an upright lever fulcrumed to the body of the machine and rovided with a pitman moving in a direction toward and from the central portion of the body is that when starting the device, the operator may forcibly push. the lever toward the central portion of the body without there being any tendency to tilt or upset the machine body.

Another advantage gained. by the use of my improved gearing device is that by having the large gear wheel connected-with and operated by the rack, the said large gear wheel may be disposed upon the machine body in a convenient position with regard to the operating lever and to the other parts of the device, and this statement is true even though different forms of racks for operating the agitator shaft are used, as is illustrated in the various modified forms shown in the drawings.

Another advantage is gained by the employment of a universal o1nt or swivel for connecting the racks, shown in Figs. III and IV with the pitmen that are attached to the large gear wheel, this advantage being that the large gear wheels may be arranged in any desired position with relation to the racks. Hence, by means of my improved gearing device, the operator, in assembling the mechanism may employ either of the kindsof racks shown and, by the use or" the swivel joint connecting the rack with the pitman that is attached to the large gear wheel, he may arrange the large gear wheel on the machine body in the most convenient position and without having the gear wheel operate in a plane parallel with the move ment of the rack. For instance, in Figs "Jill and IV, the rack swings in a horizontalplane and the gear wheel rotates in vertical plane. v
