To all whom t may concern.'

Be it known that GEORGE L. Hundes, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, new and useful Mechanism for Washing- Machines, of which the following is a speciication.`

The invention relates to clothes washing machines, and the principal object of the inl ventlon is to provide a mechanism for such stood, however,

a machine which may be driven by a motor, and which may be detachably secured to the side of an ordinary stationary tub.

A further object of the invention is to provide a mechanism which will actuate a working member moving in a practically vertical position, this bein accomplished by the use of two parallel rods which are hereinafter called the guiding and actuating rods, respectively.

A further object of the invention is to so construct the mechanism that no auxiliary supports are necessary, the working member being wholly supported and guided by said rods.

A further object is to provide such a mechanism in which the pounder element can be readily removed and in which the pounder can be held in the upper position when not in use thus giving ready access to the tub. Further objects and advantages will appear hereinafter.

While l show in the drawing and describe in the s ecilication a certain type of pounder or wasliing element it is to be understood that such a pounder forms no part ot-the present invention, and that any sort ot a device suited to wash clothes may, be substituted therefor without departing from the spirit of my invention, all such devices being designated broadly in the claims 'under the term working member. l have also shown and describedv a certain type ot mechanism for driving the actuating rod ltrom the motor. These parts, as well as a'ny other parts suited to accomplish the same result, are described andincluded broadly in the claims as mechanismdl l have also shown the washing machine in association with a wringer, this being a convenient and desirable assembly of parts for the purpose intended. llt is to be underthat the wringer terms no have invented athis member upY anddown and maintainlng it at .all times.

part of my present invention, the wringery forming a convenient means by which the support 11 may be tub., Obviously any convenient means of securing the support 1l to the tub 63 may be substituted for the wringer, and thereby reduce the cost of the apparatus, and it is further obvious that this omission of the wringer would in no way adect the scope of the invention.

Broadly described the machine consists of a motor which is mounted on a support to which the various mechanism is attached and which is itself attached` to the side of an ordinary wringer. The driving means of this wringer are so modied that the motor may drive the pounder and the wringer together or either alone, at the will of the operator.

Fig. -6 is an elevation, partly in section, of the pounder element.

Fig. 7 is a view of the invention applied to a wringer, the wringer being mounted on a tub which is shown in section.

The principal elements of the invention are a pounder l0, asupport 11 which may be secured to a wringer 12, and van electric motor 18. The motor is mounted on top of the support l1 and drives a pulley 14; through a belt 15 and a pulley 16. The pulley 14: drives a shatt 17 upon which is cut a worm 18. The worm 18 meshes with a worm gear 19 which is rigidly secured to a shaft 20 which is carried in suitable bearings in the support 11. The shaft 20 ,extends through the side of the support 11 and an eccentric 2l is mounted to turn freely thereon. Plehe eccentric 21 is surroded by an eccentric strap 22 which has an upwardly projecting ear 23. Parallel rods M and 25 are provided. being secured in castings 26 and 27, these castings being pivoted upon pins 28 and 29 secured in the support 11. llfhe casting 26 is provided with a project secured to a stationary lll@ lll@

ing end 30 which is pivoted to a pin 31 carried upon the ear 23 of the eccentric strap 22. The parallel rods 24 and 25 are secured to a casting 32 which is provided with a thumb nut 33 for the purpose of securing a pipe 34 of the pounder 10.

The construction of the pounder 1Q is plainly shown in Fig. 6. A rod 35 slides in the pipe 34 being provided with an extension 36 which extends through a small bushing 37 in the pipe 34A and is prevented from passing entirely therethrough by means of a nut 38. A spring 39 tends to hold the rod 35vin the position shown in Fig. 6. The lower end of the rod 35 is secured to a washing cone 40 which is provided with an intermediate diaphragm 41 for, the purpose of giving greater strength to this member.

A clutch member 42 is slidably keyed on the shaft 20 and is provided with an opening 43 adapted to be engaged by projections 45 on the eccentric 21.

Thev wringer 12 is of any of the well known forms being provided with two rollers, the shaft of the lower one being shown. at 46 in Figs. 2 and 4. A clutch member 47 is rigidly secured to the shaft 46 and has projections 48 thereon which 'are engaged by openings 44 in the clutch member 42. The openings 43 and 44 in the clutch 42 are of such depth that either or both the projections and 48 may be engaged.

A. yoke casting 49 is rigidly secured to a shaft 50 which slides in the support 11, as

lainly shown in Fig. 4, being moved by a ob 51. This yoke extends outwardly and engages an annular groove 52 in the clutch 42 and serves to throw the clutch either into engagement with the eccentric 21 or with the clutch member 47 on the lower shaft 46 of the wringer, or. both the eccentric and the clutch member simultaneously. 'lhel yoke 49 the wringer 12 by I d@ also extends'upwardly as shown at 53 and engages a small boss 54 on the parallel rod casting 26 when the clutch isthrown in such a manner as to actuate the wringer.

The 'shaft 50 is provided with a series of grooves 55 and the support 11 is provided with a hole 56 in which is placed a ball 57 and a spring 58, the purpose of this ball and spring being to retain the shaft 50 in any one of three positions and to require the exertion of considerable force to pull it from these positions. The motor 13 is provided with a terminal block 60 upon which are terminals to which may be attached suitable electric conductors for supplying current to the motor.

As illustrated the support 11 is made symmetrical so that may be readily reversed.

The method of operation of the invention is as follows: The support 11 is secured to means of the screws 62 d the wringer is secured to a tub 63 by any venting breaking or straining the openings 44 the relation vofthe .parts of the well known means. Water and the clothes to be washed are placed in the tub and the clutch'42 is thrown to connect the eccentric 21 to the shaft 20. Current is then passed through the motor turning the pulley 16 and driving the pulley 14 through the belt 15. The pulley 14 drives the shaft 17 and actuates the eccentric 21 through the worm gear 19, the shaft 20, and the clutch 42. The eccentric 21 rotates and swings the parallel rod 24 about the pin 28 thus raising and lowering the pounder 10. The action of conical pounders is old in the art and will not be described. The spring 39forms a resilient member and permits of the pounder 10 yielding when it strikes upon a mass of clothes or other hard substances thus premechanism. The pounder is allowed to run until the clothes are sufliciently acted upon at which time the clutch is thrown into a position where the shaft 20 drives the shaft 46. The projection 53 is allowed to pass under the boss 54, the pounder 10 being raised by hand for this purpose. If desired the pipe 34 may be entirely removed from the casting 32 by loosening the thumb nut 33. The shaft 20 is now actuated as before through the worm gear 19, the worm 18, the shaft 17, the pulley 14, the belt 15, and the pulley 16. rlhe clutch 42 is in such a position that the are engaged by the projections 48 on` the shaft 46. Since the clutch 42 is keyed to the shaft 20 the shaft 20 drives the shaft 46 which is the lower shaft of the wringer. The clothes in the tub may now be wrung out. v

By placing the shaft 50 in the central position the projections 45 and 48 are all engaged and the wringer and pounder are both actuated.

A particular utility of this invention resides in thefact that the wringer, with the washing machine mechanism attached, may be applied to any of the common formsof tubs, either stationary or portable, without modification of such tubs, and that they may be readily removed from such tubs, and when removed require but a small space for storage, and may be, if desired, stored in the tub itself.
