MATHEWJ. BEAVER, or LOYAL, WISCONSlIN,

wnsnrne Mnonrnn- Application filed September 18, 1920. Serial No. 411,040.

To all whom it may concern 7 Be it known that I, MAT EW J. BEAVER, a citizen of the United States, residing at Loyal, in the county of Clark and State of Wisconsin, have invented certain new and useful Improvements in Washing Machines,

of which the following is a specification. g The purpose of the present invention is. to provide an improved clothes Washing machine in which an alternating rotary movement is given to the clothes rubber which, at the same time, is automatically and vertically reciprocated upon the clothes with a rubbing and beater action calculated to most efiectually cleanse the clothes dur ing the operation of the machine. e

An additional object is to provide an improved type of washing machine in which the rubber element is reciprocated through V the direct action of a rotatable operating shaft and its crank portion without the interposition of gears between the rubber and the shaft. v A further object is to'provide awashing machine of simple and economical construction', designed to be easily operated and capable of being readily taken apart for repairs or cleaning whenever desired. I With the above andother objects in view,- the invention may be said generally to reside in the details of construction, combination and arrangement 'of parts as will be hereinafter more fullyrpointed out, referencebeing had to the accompanying drawings, whereini a Figure 1 is a top plan of a machine constructed in accordance with the invention.

Figure 2 is a vertical cross sectional'view taken on line 2 2 of Figure'l.

Figure 3 is a similar View taken on the line 3-3 of Figure 2 and disclosing the bend or crook forming the crank portio ofthe operating shaft, and a 1 V "Figure 4 is a vertical longitudinal sectional view of the movable cross head of the rocker element.

a In the drawings, the numeral 1 represents a tub or other suitable washing receptacle in which the clothes are deposited, such receptacle being adequately supported by suitable under supporting structure or legs 2. The tub is provided'with a cover?) to one side of which a door 4: is hingedly c011 nected. The cover and door fit into a socket or recess formed upon the inner face of the tub sides and adjacent the upperedge as 7 indicated at 5. Access to the interior of the tub is permittedonly through the opene ing of the hinged door, which however, may

be readily swung back when desired. A clothes rubber'is providedand consists r V in a disk like head 6 havingaplurality of blunt projections or fingers 6" depending from the under face thereof, the head being carried by a stem or shaft 7 inserted through a guide opening 8 in the center of the cover and provided adjacent its upper end with an enlargement recessed to provide a seat or saddle 9 for the bow 10 of the oscillating rocker element. The bow or rocker 10 is mounted betweenthe ears-or flanges ll of the saddle andis pivotally re-t tained in place by means of a bolt or other 7 suitable fastener 12. When actuated this rocker-is designed to tilt'from side to side for a purpose tobehereinafter explained.. Arranged between theends of the rocker is a cross head or connecting member 13 I preferably cylindrical in cross section and provided withan extension or laterally ofiset portion 14 as illustrated. A bore 15 extends centrally through the ofis et and transversely across the member with respect to the longitudinal axis of the latter. At

its ends of thecross head is" provided with .85 c f socket-recesses 16 for the reception 'of'pivot' I members 17 the latter being adjustably V threaded throughthe'ends of the rocker, i

- A pair of-supporting standards or brackets 18 are arranged-in alignment,- upon one side of'the central guide opening 8 of the cover and are secured to the latter asin dicated at19. These brackets are provided at their uppermost ends with bearings 20 through'which the operating shaft2lis'95 rotatably' inserted. Rigid with one end of the shaft is a large wheel 22 provided with a handle or grip23 by means of which the wheels and shaft may be manually rotated. However,any other suitable means may be employed for [rotating thesha'ftwhereby it mayj-be eitherv motor driven or-hand} operated. Crank means comprising a bend or loop 24 having angularly disposed side portions, one of which iselong'ated as at 25, is formed integral. with the shaft and provides the actuating means for the, oscillating rocker. The elongated end 25 is in sorted through the bore'1-5 of the movable cross head and is-of'smaller diameter than rotated about an axis from side to side and in a horizontal plane, thus tending to agitate or churn the hot, soapy water and stirring up the clothes to a sufficient degree. This is accomplished by reason of the novel connection provided. between the shaft 7 and the operating shaft 21, and including the crank 24, the rocker 10 and the cross head 13.

Assuming the parts, as illustrated in Figure 3, to be in neutral or starting position, the rotation of shaft 21 correspondingly rotates the crank portion 24 with the forwardly projecting inclined portion 25 of the crank describing a greater circle at its outer than at its inner end, governed of course, by the degree of inclination of the elongated portion with respect to the perpendicular. Considering the shaft as being rotated in a clockwise direction the crank 24, in making the first quarter turn will be brought to a horizontal position, the pivoted cross head or roller 18 moving freely downward with portion 25 as the latter is turned to lie in the same horizontal plane with the shaft 21. It is to be noted from Figure 8 of the drawings that at the start the crank portion 25 extends transversely across the vertical axis of the cross head 13 and at an angle thereto. Consequently, when the shaft is first rotated the crank end will be shifted within the bore 15 of the cross head so as to bind against diagonally opposite portions of the bore as indicated at X and Y respectively.

As the crank end is turned more and more from its Vertically upright position this binding action or pressure increases and since the pressure at X is on one side of the vertical axis of the shaft 7 and rocker 10, tending to be exerted in one direction and the pressure at Y on the opposite side of the axis and exerted in an opposite direction,-

the tendency is for the rocker 10 to turn about its vertical axis until it has assumed the position indicated by the dotted line structure of Figure 1, with the crank lying in the horizontal plane and completing the first quarter turn. Upon the continued rotation of the operating shaft the pressure at X and Y will of course be respectively exerted upwardly and downwardly on opposite sides of the horizontal axis of the cross head 13 which being pivotally mounted is free to revolve, allowing the crank to turn so that as the bend 24 moves upwardly the inclined portion 25 moves downwardly, the

pressure at X and Y consequently shifting so that at Y it is exerted in a lateral direction tending to move the rocker around, while at X it is exerted in the opposite di rection, tending to swing the other end of the rocker around so that by the joint action or pressure at X and Y the rocker and of course the clothes rubber, is swung back or returned to its original starting position, tl e pressure at X and Y continually shifting until at the completion of the second quarter or half turn the position of the shaft, crank and cross head 13 will be completely reversed. F or the third and last quarter turn, the operation is the same as previously described with the exception that it occurs on the reverse side of the vertical axis, the binding action at X and Y turning the rocker to the opposite side of that indicated by the dotted lines of Figure 1, from which position it is returned at the completion of the last quarter or full revolution of the shaft. It will thus be seen that upon one complete turn or revolution of the shaft the rocker and clothes element has been oscillated and toprevent any binding of the crank portion 25 andrthe cross head 13 which might, in any way affect the operativeness of the device, the rocker 10 is permitted to rock from side to side upon its pivot 11 as the shifting of the crank portion within the bore 15 of the cross head may require. It is further to be noted that as the crank revolves, the portion 25 is continually changing its position and as thecrank portion at Y moves up and around, it exerts a lifting force upon the cross head which causes the clothes rubber to be vertically reciprocated through the guide opening 8, the opening tending to hold the clothes rubber steady and firm. The reciprocation of the clothes rubber will of course occur simultaneously with the oscillation of the shaft and rocker element, these movements being rapidly effected upon the continuous rotation of the operating shaft. The movement of the clothes rubber is controlled entirely by the crank portion of the operating shaft and is governed according to the degree of inclination given to the crank portion 25. No gears are required for the transmission from the shaft to the clothes rubber and the lack of gears in no Way detracts from the efficiency of the invention.

It is thought that the construction and operation of the machine will be apparent and clearly understood from theforegoing description taken in connection with the drawings and it will be noted from the latter that no extravagant or unnecessary parts are employed to burden the utility or practicability of the invention. It is believed that the advantages of the invention may be readily understood and appreciated from the above disclosures which constitute but one form or application of the invention, it being obvious that with changes and alterations of a minor character the same may be readily adapted for and applied in various and other Ways.

Having thus described the invention'what I claim as new and desire to secure by Letters Patent is r In a driving mechanism for a Washing machine comprising a vertically disposed rotatable and reciprocatory Work shaft, a substantially semi-circular yoke pivoted at its center to the upper end of said Work shaft, a cross bar pivoted to the terminals, of said yoke, and a sleeve carried by the central the operating shaft and disposed at anangle 2 of substantially 45 degrees to the longitudinal axis of said operating shaft and slidably mounted in said sleeve.
