MANLY L. BLACKWELDER, OF CONCORD, NORTH CAROLINA, ASSIGNOR OF ONE-HALF TO DANIEL R. HOOVER, OF SAME PLACE.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 378,919, dated March 6, 1888.

Application filed April 20, 1887.

To aZZ whom it may concern:

Be it known that I, MANLY L. BLAOKWELDER,

a citizen of the United States, residing at Concord, in the county of Cabarrus and State of North Carolina, have invented certain new and useful Improvements in Washing-Machines, of which the following is a full, clear, and exact description.

The object of this invention is to provide a washing'machine economical in construction, durable, and effective in operation.

The invention relates to that class of washing-machines in which the suds -box, so called, or body is arranged to be rocked in order to give the necessary motion-to the garments being washed; and the invention has special reference to means for rocking the body and for holding the body stationary when so desired.

As hereinafter particularly set forth and claimed, the invention consists in a suds-box or body provided with lateral journals or trunnions, preferably made of wood, and of proportionately large diameter, so as to be readily reversible when worn, and provided with one or more diametrical grooves, combined with a standard or pedestal having a swinging locking device cooperating with the journals to hold the suds-box or body stationary when desired, and adapted to be disconnected therefrom to permit freedom of motion of the said suds-box.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure l is a side elevation; Fig. 2, a sectional end elevation, and Fig. 3 is a perspective view of a detached trunnion.

The body a is elliptical or oval in shape,and preferably composed of wooden side pieces, I), and a metal periphery, c, secured to the said side pieces. This body is provided with any suitable cover, d, and an operating-handle, e, and at onev end has an emptying-faucet, f. The body may be provided on the inside with any usual rubbing-surfaces, 9, either arranged on its sides or crosswise of its bottom. The sides I) are centrally provided with journals h, projecting laterally therefrom. These journals or trunnions are for economys sake made of wood, and are circular in shape, and are secured to Serial No. 235,533. (No model.)

the sides of the suds-box,fi1st by center bolts, 1', on which they may be rotated, and also by means of screws or other fastenings, j.

The base or pedestal or standard It is composed of two side pieces, Z, rigidly connected by cross-pieces m and a center brace, a. In the upper edges of these side pieces, Z, semicircular cavities o are made, of a radius equal to or slightly greater than the radius of the journals or trunnions; and these said cavities form bearings or boxes in which the journals or trunnions rotate, the said suds-box or body being supported by its said journals or trunnions in the cavities 0 in the side pleces, Z.

The outer faces of the trunnions or journals are provided with one or more diametrical grooves, 10, and one of the side pieces, Z, of the frame is provided with a swinging loop, or, as I have herein termed it, a locking device, 1", which may be conveniently made of a piece of bar or strap metal. This locking device 1" is pivoted to the said suds-box, so as to be swung into and out of the grooves in the journals or trunnions, as indicated by full and dotted lines, respectively, in Fig. 2. By providing the trunnions or journals with more than one groove 19 the suds-boxer body may be held stationary in a horizontal or other position when it is desired to insert or remove the garments. 4

By making the journals or trunnions of the proportional diameter indicated in the drawings a very steady motion is given to the suds-box without thereby rendering its operation difficult or laborious.

When the trunnions or j ournals become worn, the fastenings j may be removed and the bolt 5 loosened, and said journals then turned upside down or rotated on their bolts sufficient to bring a fresh and unworn surface into the bearings'o.

By the use of a locking device, 1', extending entirely across a very wide journal the sudsboX is held very firmly.

What I claim is-- 95 1. Awashing-machine consisting of a swinging body or suds-box, lateral trunnions, one of which is provided with diametrical end grooves, a frame having bearings to receive said trunnions, and a swinging locking device arranged upon said frame to engage one or another of the grooves in said journal, substanbined and arranged substantially as described.
