WASHING-MACHINE Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed April 2'7, 1906. Serial No. 314,076.

To all whom it may concern:

Be it known that 1, JOHN S. MODANIEL, a citizen of the United States, residing at Lebanon, in the county of Boone and State of Indiana, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

This invention relates to machines for washing clothes having two semi-cylindrical rubbers working one within the other, said rubbers being actuated so as to move in opposite directions to each other.

The object of the invention is to provide means for regulating the amount of friction between the two rubbers by regulating the pressure imparted by the operator to the top rubber.

The object also is to provide a washing machine in which the interior can be readily reached for the introduction inspection and removal of the clothes.

A further object of the invention is to provide a simple and durable machine which will be inexpensive to construct and readily understood and easily operated by any person of ordinary intelligence.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a view in side elevation of my improved washing machine showing some of the parts broken away and in vertical section to more fully illustrate the construction of the machine. Fig. 2 is a detail in front elevation and partial vertical section of the machine, and particularly shows the levers for operating the rubbers. Fig. 3 is a transverse vertical section on the line 33 of Fig. 1.

Like characters of reference indicate like parts throughout the several views.

4 represents the body portion or suds box of the ma chine, which is semi-cylindrical in form, and is supported upon the legs 5.

6 represents the larger or outside rubber which has semi-circular ends and semi-cylindrical sides formed out of rectangular slats 7, fastened to and supported by said sides. At the center of this semi-cylindrical rubber are the two outwardly projected

trunnions

8 and 9. The trunnion 9 has the downwardly extended arm or crank-portion 10 which terminates with the crank-pin 11. The

trunnions

8 and 9 are supported by the walls of the suds box 4.

12 is the box-like cover of the machine, and has the vertical slots 13 extending upwardly from the

trunnions

8 and 9.

and construction to the first rubber, but smaller in size so as to go within the hollow interior of the first rubber within which it is mounted and operates. The rubber 14 has a semi-cylindrical surface covered with transverse V-shaped ribs of usual construction. The rubber 14 has the centrally located trunnions 16 which are placed so as to project through the slots 13 of the top 12.

14 is a second rubber similar in shape The slots 13 permit the rubber to be adjusted vertically so as to increase the distance between the rubbing faces of the two rubbers, while also confining the trunnions 16 within such bounds as to secure a rocking movement of the rubber 14 within the limits of the first or outside rubber. The semi-circular sides of the rubber 14 are joined together by means of the transverse board 18, and this board forms a means for the'attachment to the rubber of a standard 19. The top 12 of the machine has an elongated slot 20, through which the standard 19 passes in the manner shown in the drawing.

Secured to the body 4 of the machine are the brackets 21, having boxes at their outer ends in which a shaft 22 is mounted. The outer end of the shaft 22 has the fixed arm 23 which is connected by means of the crank-bar 24 with the crank-pin 11 on the end of the arm 10, whereby by the rocking of the shaft 22 the outside rubber6will be correspondingly inoved or rocked. Mounted loosely V on the reduced opposite end of the shaft 22, between the two brackets 21 and adjacent to the inside bracket is the lever 25, and carried by the shaft 22 is the fixed arm 26 which is extended for a suitable distance above the shaft 22 and is connected by means of the crank-bar 28 with the upper end of the standard 19 whereby, by the rocking of the shaft 22, the upper rubber 14 will be rocked, but, because the standard 19 and the arm 10 diverge in opposite directions from the axes of the two rubbers, their relative rocking movements will be in opposite directions, which is desirable for securing the greatest efliciency in the work of the machine.

30 is the operating handle or lever, the lower end of which is pivotally secured to the lever 25. This lever 30 is also pivotally secured to the lever 28, and it is provided with the handles 32 at its upper end. The dis tance from the lever 30 to each end of the lever 28, and

I the lengths of the

arms

25 and 26 are proportioned so that a downward pressure applied at the handles 32 of the handle-bar 30 will exert an appreciable pressure in a downward direction upon the rubber 14, but the pressure does not want to be great enough to endanger the tearing of the clothes which might readily follow if the pressure was multiplied by an injudicious leverage construction.

It will be noted that the arm or lever 25 extends downwardly in an oblique direction from the shaft 22 so as to cause the weight or pressure on handles 32 to act in a manner to depress the long arm of the lever 28 and bear down on the rubber 14 at all working positions of the lever 30.

Having thus fully described my invention, what I claim as new and wish to secure by Letters Patent of the United States, is

1. In a washing machine, a suds box, a semi-cylindrical rubber mounted on trunnions in said box, a crank connected with the rubber, a second rubber mounted on trunnions and entering the first rubber, said second rubber having a vertical standard, a rock-shaft mounted outside of the suds box, said rock-shaft having two fixed arms, a crank-bar connecting one of said arms with the crank of the first rubber and a second crank-bar connecting the other arm with the standard from said second rubber, a lever loosely mounted on the rock-shaft and a hand lever pivotally secured at its lower end to the lever loosely mounted on the rock-shaft and pivotally secured at a point above its lower end to said second crank-bar.

2. In a washing machine, a suds box, a semi-cylindrical rubber mounted in said box on trunnions, a crank connected with one of the trunnions and extending in a downward direction on the outside of the suds box, a second rubber mounted within the first and capable of a rocking movement, said second rubber having an upwardly extended standard, :1 rock-shaft mounted on brackets outside of the suds box, said rockshaft having two upwardly extended fixed arms, a crank-bar connecting one of said arms with the crank of the first rubber and a second crank-bar connecting the other arm with the standard from said second rubber, a lever loosely mounted on the rock-shaft and extending obliquely in a downward direction, and a hand-lever pivoted at its lower end to said loose lever and above said lower end to the crank-bar which connects one of the fixed arms of the rock-shaft with the standard of the top rubber.

3. In a washing machine, a suds box, an inverted box forming a cover to said suds box, said cover having vertical slots in its opposite sides, a semi-cylindrical rubber pivotally mounted within the suds box so as to be capable of a rocking movement, said rubber having a crank-arid extending in a downward direction on the outside of the suds box, a second rubber mounted within the first rubber and having pivots projecting into the vertical slots of the cover, said rubber also having a vertical standard which passes through a slot in the top of the 'cover and terminates outside of the cover, a rock-shaft supported on horizontal brackets extending outside of and from the suds box, said rockshaft having two upwardly projecting fixedarms, a crank-bar connecting one of these arms with the crank of the first rubber, a second crank-bar connecting the other vertical arm with the standard extension from the second rubber a lever loosely mounted on the rock shaft and extending obliquely in a downward direction and a hand-lever pivoted at its lower end to the oblique loose lever and at a point above its lower end to the crank-bar extending from the second arm of the rockshaft to the standard of the second rubber said last mentioned crankbar being bent upwardly and after passing. the top of said suds-box cover being bent back into a horizontal position and carried thence above the cover to the standard so as to avoid conflict with the coverin the operation of the machine.

In witness whereof, I, have hereunto set my hand and .seal at Indianapolis, Indiana, this 20th day of April,

A. D.. one thousand nine hundred and six.
