WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,465, dated February S, 1881.

` Application ined December 11, 1880. (Model.)

To all 'whom it may concern:

Be it known that I, RANsoM G. BALDWIN, of Oskaloosa,in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare that the followingis a full, clear, and exact description of the invent-ion, which appertains to make and use the same, reference being had to the aecompan yin g drawings, which form a part of this specication, and in which- Figure l is a perspective inside view of the suds-box. Fig.2 is a longitudinal vertical section of the same. Fig. 3 is a perspective view of the operating mechanism. Fig. 4 is a similar view ot' the agitator with its clutch-plates. Figs. 5 and 6 are perspective views of respectively the upper and under clutch-plate; and Fig. 7 is a perspective View of one corner of the removable tray, showing the channels for draining the water from the tray.

Similar letters of reference indicate correspending parts in all the figures.`

My invention has relation to rotary reciprocating washing-machines, or so-called agitator77 washing-machines and it consists in certain improvements in the construction of the suds-box and in the device for attaching the agitator to the pinion-shaft, as hereinafter more fully described,and particularly pointed out in the claims.

In the annexed drawings, A represents the suds-box, which is, by preference, rectangular in shape, and elevated upon suitable legs or supports. (Not shown in the drawings.) In the bottom of the box is a piece of sheet-zinc," B, to prevent leakage, over which is placed a wooden tray, C, made `with cleats a around its edges, by means of which the tray may be nailed to the sides of the suds-box. In each corner of the tray is a detachable board, D, set on edge, with its upper front corner cut ofi, as shownr iu the drawings. By making dovetailed grooves in each corner of the tray and dovetailing the under side of each of the ,boards D these may readily be detached from and reinserted into the tray, as occasion requires. The two boardsD, at that end of the suds-box where the outlet is arranged, are cut away, also at the corner which impinges upon stud, f, at each of its corners.

the box, as shown at d, Fig. 7 ,and the contiguous ends of `the cleats a are also cut oif, so as to form channels l), through which the water in the box may find its way to the outlet; otherwise some of the water and suds would eollect in the corners of the box without finding a ready means ot' escape.

By the use of the tray C in the manner described the clothes do not come in con tact with 6o the zinc bottom, which is undesirable for the following reason: If'the wooden bottom warps or the sides of the machine shrink in drying, the zinc bottom will bulge 0r be raised at places in an upward direction, so as to form creases or wrinkles. The dirt from the clothes and the rotaryr reciprocating motion of these over the bulged or corrugated zine bottom will soon cause this to be worn through at the most exposed places, where the friction is greatest, 7o forming holes with jagged edges which will tear the clothes, and themaehine is useless.

The wooden tray is easily cleaned after each washing, andthe'zine bottom, while eifectually preventing leakage, will last as long as any other part of the machine.

The agitator consists of a wooden cross, E, with a'wooden peg, F, inserted into the end of each of its arms. It is secured upon the end of the pinion-shaft G, which is iiattened 8o on opposite sides by means of an upper `and an under clutch-plate, shown respectively at H and I, the upper plate, H, being cast with lugs c c on its upper face, on opposite sides of the central aperture, e, for the insertion of the 8 5 pinion-shaft, and with a downward-projecting The lower plate,

I, is of a similar shape and construction, but not so heavy, and is cast with four upwardprojecting corner-studs, g; nor has it lugs on 9o the sides of its central aperture, as the top plate. The combination of these two clutchplates with the agitator-cross and its pinionshaft will be readily understood by reference to the drawings. The upper clutch-plate is rst inserted upon the shaft with its lugs c c bearin g against its attened sides. The cross E is then slipped upon the shaft with its arms between the downward-projecting studs f, after which the bottom plate, I, is slipped upon Ioo the pinion and its studs g inserted into the corners ot' the cross, after which it is screwed up against the cross and securely fastened by the nut K. The studs fg of respectively the upper and the lower clutch-plate are filed to such a height that when the lower plate is screwed up home by the nut there will be a narrow space between the points of opposite studs-in other words, they do not quite meet. These corner-studs of the two plates will effectually prevent displacement of the arms of the cross placed between them, and the bottom platt-3,1, prevents wear and warping of the cross at the point where it is attached to the pinion-shaft, which is not the case where simply a nut and a washer are employed to hold the cross in its place'ilpon the clutch-plate H. The pinion-shaft is operated by a pinion, L, whichmeshes with the cogged drive-wheel M. This wheel is cast with two radial sockets, m m, in a line with one another, either one of which is adapted to receive the handle N, which is held rmly in place in its socket by a screw or nutted bolt, n, so that when the cogs on one side of the drive-wheel are worn out those on the other half may be brought into requisition by simply shifting the handle to the other socket, and the wheel is as good as new.

In washing carpets or similar heavy and bulky articles the corner-boards D are removed from the tray.

Iam well aware that it is not new in machines of this class to secure the agitator upon `its pinion-shaft by means of a studded plate having two or more downwardprojecting studs, which (3o-operates with an ordinary washer and nut on the under side of the agitator. By the. arrangement of an upper and a lower instead of a single studded holdingplate, in the manner described, a web of wood is left untouched by the studs in each corner of the agitator, inasmuch as opposite studs do not meet each other. The lower studded plate, l, also effect-ually prevents wear and warping of the middle part of the agitator, as I have already pointed out Vin describing that part of my invention.

I claim and desire to secure by Letters Patent of the United Statesl. In a rotary reciprocating washing-machine, the suds-box A, having a zinc bottom, B, and wooden tra-y C, provided with the detachable corner wings or boards D, as set forth.

2. In a rotary reciprocating washingmachine, the suds-box A, having a zinc bottom, B, and wooden tray C, provided with the detachable corner wings or boards D, cleats a, and channels b d, as set forth.

f 3. In a rotary reciprocating washingmachine, the combination, with the agitator and its pinion-shaft, of the upper studded holdingplate, H, lower studded holding-plate, I, and nut K, substantially in the manner and for the purpose herein shown and specified.`

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

RANSOM G. BALDWIN.
