PATENT GEORGE \V. BALLARD, OF DETROIT, MICHIGAN.

WASHING-MACHINE.

. $PECIFIGATION forming part of Letters Patent No. 425,397, dated April 15, 1890.

Application filed August 22, 1889.

To all? whom it may concern.-

Be it known that I, GEORGE W. BALLARD, of the city of Detroit, in the county of lVayne and State of Michigan, have invented a new and useful Improvement in Washing-Machines, of which the following is a specification.

My invention relates to improvements in washing-machines; and the object of my invention is to provide an improved machine for clean sing clothes by forcing water through the interstices of the cloth. I attain this objeot in the device illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of one end of the trough for containing the water, sho W- in g the operating mechanism in elevation, the frame B and the piston contained therein being shown in section. Fig. 2 is a plan view of the parts shown in Fig. 1. Fig.3 is aplan view of the frame 13 and the piston contained therein; and Fig. lis a section on the line w a, Fig. 3.

Similar letters refer to similar partsthroughout the several views.

A is a rectangular oblong trough for containing the water for washing the clothes.

G is a perforated diaphragm supported parallel to and a short distance from the bottom of the trough A. H

B B are oblong frames open at both ends, into which are fitted the pistons D D.

E is a platform resting upon the upper edges of the longer sides of the trough A, and adapted to slide thereon in the direction of the length of the trough.

F F are standards rising vertically from the platform E.

G G are two arcs rigidly secured together by the frame H, and forming parts of circles having their centers at the center of the frame H. The frame II is pivoted at its center in the upper ends of the standards F F, so to oscillate in a vertical plane.

R is a handle for oscillating the frame 11.

I I are rectangular bars rigidly secured to the centers of the pistons D D and extending vertically therefrom.

2' i are teeth formed along the sides of the bars I I which face each other. Said bars $erie1 No. 321,733. (No model.)

extend through and slide in rectangular holes in the platform E, the teeth upon their sides engaging with the teeth of the arcs G G.

J' J are slabs extending across the upper ends of the frames B B and rigidly secured thereto. The bars I I are adapted to slide through rectangular holes in the slabs J J K K K K are springs secured to the slabs J .I, respectively, and act by their elasticity to draw the pistons D D to the top of the frames B B.

L L are holes formed, respectively, through the pistons D D, and M H are flaps secured to the under side of the pistons D D, respect ively, and adapted to prevent water or air from passing upward through the holes L L and allow them to pass freely downward through said holes.

N N are holes passing horizontally through the frames B B, respectively, a short distance from their tops.

0 O are guards for deflecting downward any jets of water which may pass through the holes N N.

P P are thumb-screws passing through lugs Q Q, respectively, and adapted to limit the upward travel of the pistons D D.

The operation of the above-described device is as follows: The trough A being partially filled with water, the clothes to be cleansed are laid upon the perforated diaphragm C. The operator then oscillates the frame II by means of the handle R, forcing the frame B down upon the clothes. After the frame B rests upon the clothes the downward pressure upon the bar I is continued, forcing the piston D down in the frame B and driving the water below said piston out at the lower end of the frame B against and through the cloth. WVhen the frame 13 is raised, the piston is returned to the top of said frame by the springs K K, the water passing down through the holeL to fill the space below said piston. lVhen the level of the water in the trough is below the lower end of the frame B at the highest position of said frame the air passes out of the holes N N, when said frame descend allowing the water to fill up the space below the piston D. \Vhen there area number of thicknesses of cloth over the diaphragm C, it is found difficult to force the Water through the cloth. In this case the thumbscrews P P are set so that the piston D cannot rise above the holes N N, When there will be only air under said piston, which will act to drive the Water in the clothes out, which operation does not require as much pressure as Where the water is driven into the clothes as in the first operation described. moved along the length of the trough A, so as to reach all the clothes that may be therein. The perforated diaphragm keeps the clothes off the bottom of the trough, thus allowing the Water to circulate through them more easily. The construction and operation of the frame B are the same as. that of the frame B.

Having fully described my invention, what The platform E is I claim, and'desire to secure by Letters Patcut, is-

In a washing-machine, substantially as described, the combination of frame B, open at both ends and provided with a series of holes near its upper end, means for raising and pressing down the frame upon the clothes, a piston Within said frame, means, substantially as described, for reciprocating said piston in said frame, and adjustable stops, substantially as described, attached to said frame to limit the upward motion of said piston, substantially as shown and described. 1 GEORGE W.
