.To aZZ whom it may concern:

Be it known that I, FRED D. HARDING, a ci tizen of the United States, residing at Baldwin, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in VVashing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,

' such as will enable others skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in washing-machines, and more particularly to that class of machines wherein a corrugated roller is caused to travel back and forth over a corrugated board and an intermittent stream of water is caused to be thrown upon the board. It is designed to make a machine simple in construction, convenientin use, and efficient in operation.

In the drawings herewith accompanying and making a part of this application, Figure 1 is a perspective view of my improved machine. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a detail plan view of a portion of the board, the bracket which supports the board, 8270. Fig. 4 is a perspective view of the plunger and the frame which carries it.

In said drawings, A is a tank of any suitable size, shape, and material. It is mounted on legs 13 and has standards 0 secured to the sides thereof. The scrubbing-board D is supported on brackets E, attached to the sides of the tank, the brackets having curved flanges F on the forward ends to support the roller when not in use and lugs G on the opposite ends, which limit the backward movement of the roller. The brackets have offsets H, which support the brackets away from the sides of the tank and thus form long narrow open spaces I and spaces J beyond the offsets H between the brackets and tank. The flanges being curved and extending beyond the offsets yield slightly to receive and hold the roller when not in use, the flange itself or the side of the tank being somewhat flexible. The

board in a longitudinal direction is slightly curved. In the front end of the tank is set an angle-plate K, which forms, with the front end and bottom of the tank, the conduit L,

through which the water from the tank is thrown upon the board. The top of this plate is turned out at right angles to the wall, as seen at M, and the bottom. is turned up at right angles, as seen at N. It is provided with a series of holes 0, which permit the water to flow back into the bottom of the tank. Secured to the front wall, above the end M of plate K, is a plate P, the lower end being bent forward and forming, with the end M, the orifice of the conduit opening toward and adapted to direct the water passing therethrough upon the board. To make the orifice adjustable, I insert the edge of plate K under a retaining-strip Q, the upper end of which is tightly soldered or otherwise secured to the tank. Bolts R pass through the tank, strip, and plate, and the plate may be adjusted vertically by having the bolts pass through slots S in the plate. Suspended in slots T in the top of standards 0 is a rectangular frame U, in the bottom of which is journaled a corrugated roller V. Projecting rearwardly therefrom are brackets W, to which is secured a handle W for operating the roller. A cross bar X connects the tops of the standards, and between the top of the swinging frame and cross-bar are springs Y, which hold the roller normally down upon the board, but yield sufficiently to allow the roller to pass over any thickness of material that may be on the board. In the horizontal part of the conduit formed by the bottom of the tank and the plate before mentioned is a plunger a, pivotally and eccentrically mounted in the end of a rectangular frame b. The free edge of the plunger is in advance of the pivotpoint, so that the resistance of the water causes it to drop down and fill the conduit when being driven forward and to float up and allow a fresh supply of water to enter the conduit when being drawn back. The first position is shown in Fig. 2 and the second position is shown in dotted lines in the same figure. Pivotaily and centrally secured to the inside of each of the standards is alever c, the upper end being pivotally connected with the swinging frame and the lower end with the frame which crrries the plunger. The upper end of the lever has a vertical slot 01 therein, through which the pivot-pin e passes and which permits the swinging frame to rise to allow the roller to pass over the material on the board and the lever to swing beyond the pivot-point. To prevent the sides of the swinging frame from coming in contact with the edge of the lever, I attach to the sides of the tank longitudinal strips f, which extend over said lever. The space from the rear end of the board to the bottom of the tank is filled with a piece of netting g. It will be seen that the space beneath the board, the conduit, and plunger are all separated from the main portion of the tank, thus ob- Viating all danger of the material being drawn under the board or into the conduit. The corrugationsin the roller are somewhat deeper than those in the board with which they register, thus forming little reservoirs at the inner portions of the grooves in the roller. The advantages of this arrangement are that the water is forced through the material into the little reservoir formed between the material and the bottom of the flutes on the roller, which forcing of the water entirely through the clothes aids materially in the cleansing process. Likewise the greater depth of the flutes in the rollertends to draw the material out of the flutes in the board immediately in front of the flutes in mesh, so that water gathers in the little reservoirs be tween the bottom of the flutes and the clothes on the board, and when the flutesin the board and roller mesh the water is forced through the clothes instead of, as is usual when the clothes remain pressed closely into the flutes, forcing the water down upon the top of the clothes. This also increases very much the eificiency of the washing.

The operation of the plunger is apparent. \Vhen the swinging frame is drawn back the lever drives the plunger forward in the horizontal part of the conduit, the plunger filling the conduit and forcing water upward and forward upon the board. When the swinging frame is pushed forward, the lever draws the plunger back, the edge of the plunger floating up to permit a fresh supply of water to enter the conduit from the tank.

Having thus described my invention and its use, Iclaim 1. In a washing-machine, a suitable tank, a corrugated scrubbing-board, an angle-plate forming, with the bottom and end of the tank, a conduit for discharge of water upon the board, a frame adapted to reciprocate in the horizontal part of said conduit, a plunger pivotally mounted in said frame, a swinging corrugated rollerand means for reciprocating said frame and plunger, substantially as and for the purposes set forth.
