IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 35,025, dated April 22, 1862.

"To all whom it 712/667] concern:

Be it known that I, SHELDEN HULL, of OX- ford, in the county of New Haven and. State of Connecticut, have invented a new and Improved Clothes-\Vashing Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a plan or top view of my invention; Fig. 2, a side sectional view of the same, taken in the line as, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

This invention relates to an improved clothes -washing machine of that class in which plungers are used and the clothes cleansed by compressing them in the suds and forcing the latter through them.

The object of the invention is to obtain a simple and efficient machine of the class specified, and which will perform its work more rapidly than hitherto without injury to the clothes and with a moderate application of power.

The invention consists in the employment or use of a V-shaped box having an upright attached to one of its sides, from which is suspended a swinging bar or frame having a plunger-rod attached to each end of it, the plungers of which are peculiarly arranged, and all the parts combined to operate as hereinafter described to effect the desired result.

To enable those skilled in the art to fully understand and construct my inventirm, I will proceed to describe it.

A represents a V-shaped box, which is attached to and supported by a suitable base, B. To one side of this box A there is secured an upright, C, the upper end of which is curved inward over the box A, and has a bar, D, suspended loosely from it by a pivot or bolt, (I. The bar I) has a bar, E, rigidly at tached to its lower end at right angles. The bar E is nearly or quite equal in length to the upper end of the box A, and to each end of said bar E there is secured by a point or bolt, 1), a plunger-rod, F.

G G represent the plungers, which are formed each of a series of parallel plates or wooden strips, 0, of suitable thickness, placed and secured at a suitable distance apart on rods d. (See Fig. 1.) In the back part of each plunger G G there are placed frictionrollers e, which bear on the inner surfaces of the inclined ends ff of the box A, and are designed to obviate friction.

The lower edges of the plates or strips 0 of the plunger G are at right angles to the edges which are parallel with the end f on which said plunger rests; but the lower edges of the plates or strips 0 of the plunger Gform acute angles with their edges which are parallel with the end f on which said plunger rests and works. This is clearly shown in Fig. 2.

The box A, as well as the plungers and other parts of the machine, may be of wood. The bolts or joints may be of metal, if desired.

The operation is as follows: The clothes to be washed are placed in the box A, which is supplied with a requisite quantity of suds, and the bar E is vibrated or swung by the operator, the bar D working on the pivot or bolt a. As the bar E is thus operated the plungers G G rise and fall and act alternately upon the clothes, which are compressed and rotated while immersed in the suds. The turning of the clothes is effected by the plunger G in consequence of its oblique end, the obliquity of the lower ends of the plates or strips 0 of said plunger having atendency as they descend to force upward the clothes on the opposite end f of the box A and partially turn them beneath the plunger G, so that both plungers, each time they descend, act upon a fresh surface of the clothes, and consequently all parts of the latter will be cleaned.

The bar E is suspended in a state of equipoise, the plungers being of equal weight, and hence the machine may be operated with but little labor. The plungers may also be made to operate at a greater or less distance apart by shortening or taking up the rods F, which may be done by having a series of holes, g, made in them, through either of which the bolts 1) may pass. Thewhole arrangement, it will be seen, is extremely simple and eflicient. The spaces between the plates or strips 0 of the plunger admit of the latter passing freely through the suds.

Having thus described my invention, What edges at right angles with the end on the I claim as new, and desire to secure by. Letters Patent, isi 1. The V-shaped box A, in combination with the swingingbar E and the plungers G i G, attached thereto and Working on the inclined endsf of the box, substai'itially as and for the purpose set forth.

2. Constructing the plungers G G of a series of parallel plates or strips 0, the plates or strips 0 of one plunger, G, having their lower box on Which their plunger Works, and the plates or strips 0 of the other plunger, G, having their lower edges forming an acute angle with the end f 011 the box on which their plunger works, substantially as and for the purpose specified.
