WASHING- SPI-ICIPICATION forming part of Letters MACHINE.

Patent No. 370,854, dated October 4, 1887.

Application filed December 11, 1886. Serial No. 221,295. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE G. CHAMBER- LAIN and LINCOLN P. OLINE, both residents of Bank Centre, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Washing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use for securing the parts together.

Similarnumerals of reference indicate corresponding parts in all the figures.

'Our invention has relation to that class of washing-machines in which the clothes to be washed are inclosed in a suds-box rocking on trunnions and having ribs upon its inner sides, against which the clothes may rub as the box is rocked and it consists in the improved construction and combination of parts of such a washing-machine, as hereinafter more fully described and claimed. I

In the accompanying drawings, the numerals 1 indicate four legs arranged in two diverging pairs, having their upper ends secured in triangular castings 2, formed with bearings 3 for the trunnions of the suds-box apd having the lower portions of each pair of diverging legs united by means of cross-pieces 4:, having their ends secured to the innersides of the said legs by means of screws 5, passing through the legs into the ends of the crosspieces, as shown in Fig. 5.

The suds-box 6 has a rounded bottom, 7, which has its ends curved upward and inward, as shown at 8, the ends forming an opening at the upper side of the box, and the said bottom is secured with its side edges to the edges of the side pieces, 9, which are nearly oval in shape, having, however, their lower edges more convex than the upper edges, which are I formed with straight central portions, 10, at

the ends of the aperture in the top of the box.

The side pieces have two castings, l1 and 12, secured to them near the upper edges, and the said castings are formed with trunnions 13 at their lower ends, which trunnions rock in the bearings formed in the triangular castings securing the upper ends of the legs together. One, 11, of these castings is formed with a vertical recess, 14, in its inner side, having downwardly-projecting teeth or serrations 15.upon its sides, and the side edges of the casting are formed with perforated lips 16 for the insertion of fastening-screws 17, by means of which the casting is secured to the side piece, the recess and the side piece forming a socket for the insertion of the handle 18, by means of which the suds-box may be reciprocated, the serrations or teeth serving to secure the handle in the socket. The other casting, 12, is provided with perforated lips 19 upon its side edges for the insertion of fastening-screws 20, and the upper portion of the casting projects above the upper edge of the side piece, a board, 21, being secured to the upper portion of the casting, which board serves for the purpose of securing a wringer to the suds-box when it is desired.

The edges of the aperture in the top of the suds-box are provided with diverging flanges 22, and the ends of the board, to which a wringer may be secured, are cut off at their lower corners to correspond to the incline of the said flanges, the said corners resting upon the ends of the flanges.

The side pieces of the suds-box are provided with a number of horizontal strips, 23,0r cleats, which strips are united at their middles by means-of a vertical board or wide strip, 24, the upper end of which extends to a short distance below the upper edge of the upper crosspiece, forming an offset for the end of a cover to rest upon.

Transverse cleats or cross-pieces 25 are secured with their ends to the upper cross-pieces upon the side pieces of the suds-box, and these cross-pieces or cleats are rabbetted, as shown at'26, the bottoms of the rabbets being level with the upper ends of the vertical boards, the said rabbets and boards serving to support a cover, 27, which may rest with its edges and ends upon the rabbets and boards covering the aperture in the top of the suds-box.

A number of transverse ribs, 28, are secured with their ends in the cross-pieces upon the side pieces of the box and pass across the bottom and its upwardly and inwardly curved ends, forming rubbing-ribs for the contents-of the box, the ribs being sufficiently raised from the said bottom to allow the water and suds to pass freely between them and the bottom.

The cover 29 has grooves 30 in the edges of its ends, and cleats 31, having tongues 32 upon their inner edges,are secured with the tongues fitting in the grooves, the said cleats preventing the cover from warping by the action of the water, suds, and steam within the sudsbox.

The cover is secured over the aperture in the top of the suds-box by means of the loweredge of the board for the attachment of the wringer, the lower edge of which board bears'against one end of the cover, which rests upon the rabbeted cleats and upon the upper ends of the vertical boards upon the side pieces, and a spring, 33, serves to secure the other end of the cover, the said spring being capable of being bent back for thepurpose of allowing the cover to be raised at that end and removed.

A hook, 34, is pivoted upon one of the supporting-legs of the machine and engages an eye, 35, upon the suds box for the purpose of securing the suds-box when the wringer is to be used, or whenever it is desired to hold the suds-box steady without rocking.

When the machine is to be used, the suds box is filled with hot suds and the clothes are placed in the box, whereupon the cover is placed in position and the box rocked by means of the handle, when it will be seen that the clothes will be rubbed against the transverse ribs upon the bottom and sides of the box,while the water and suds are so agitated that they will pass through and over the clothes from all sides, thoroughly washing the clothes.

The upwardly and inwardly curved ends of the bottom of the suds-box will serve to guide the suds and water in an upward direction, from which it will fall down upon the'clothes, and the curved ends of the suds-box will also cause the clothes to be rolled and turned when they arrive at the ends of the box while being rocked, so that all surfaces will be subjected to the rubbing action against the ribs.

By making the entire suds box of sheetmetal all warping of the same is prevented, and the metal is galvanized or otherwise rendered rust-proof, so that it will not stain the clothes.

The supporting-frame for the box may be easily taken apart for transportation and again be easily put together by the aid of a screw-driver, the triangular castings being secured to the upper ends of the legs by means of screws, and the cross-pieces connecting the lower portions of the legs are secured to the legs by means of screws, which may easily be inserted through the legs into the ends of the cross-pieces.

The handle is held in its socket by means of the serrations or teeth upon the sides of the recess in the inner side of the casting, being simply secured in the socket by being driven into it, when it cannot be withdrawn without removing the casting from the suds-box.

The board at the upper edge of one of the side pieces of the suds-box may have a wringer. secured upon it, and the clothes may be wrung out by the said wringcr, the inclined flanges at the edges of the top aperture preventing the water and suds from flowing over the edges of the aperture and guiding the same into the suds-box.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States-- 1. In a washing-machine, the combination of a sheet-metal suds-box having its curved bottom curved upward and inward at its ends to form a transverse central top aperture,having diverging flanges at its side edges, a casting secured to one side piece, having a trunnion atitslower end,andhaving its upper portion projecting above the upper edge ofthe side piece, a trunnion upon the other side of said suds-receptacle, and aboard secured to the upper portion of the casting and having its lower edge resting upon the upper edge of the side piece at the end of the top aperture, and having its lower corners cut off obliquely to rest upon the inclined flanges, the board serving for the attachment of awringer, as and for the purpose shown and set forth.

2. In a washing machine, the combination ofa suds-box having a trunnion at one side piece, a casting upon the other side piece,having a trunnion at its lower end corresponding to the other trunnion, and having a vertical recess in its inner side formed with toothed or serrated sides, forming a socket with the side of the suds-box, and ahandle inserted into the socket and secured by the serrations, as and for the purpose shown and set forth.

In testimony that we claim the foregoing as our own we'have hereunto afiixed our signatures in presence of two witnesses.
