FRIEDRICH SOHUMPE, OF CINCINNATI, OHIO, ASSIGNOR.OF ONE-HALF TO JOHN M. HAMMELRATH, OF SAME PLACE.

WASHBNG MAGHINE.

SPECIFICATION forming part of Letters Patent No. 380,939, dated April 10, 1888.

Application filed June 16, 1887. Serial No. 241,462. (No model.)

To aZZ whom it may concern:

Be it known that I, FRIEDRICH SOHUMPE, a citizen of the United States, residing at Oincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawlngs.

This invention relates to those washing-machines which include a concave tub having a rubber adapted to vibrate therein; and my improvement comprises a novel construction of rubber, which insures the most thorough agitation of the clothes and circulation of the suds within the tub,'as hereinafter more fully described.

In the annexed drawings, Figure l-is a vertical section of my improved washingmachine, taken in the plane of the vibrating lever, a portion of the rubber being sectioned. Fig. 2 is an enlarged transverse section of the rubber, Fig. 3 is a longitudinal section of the rubber, taken in the plane of the lever. Fig. 4 shows the two sections of the lever coupled together in an erect position.

A represents an ordinary tub mounted upon feet a, and having a concave bottom, B, provided with a series of transverse ribs or corrugations, b.

- C is the lid, hinged to the opposite sides of the tub and near one end thereof, one of these hinges or pivots being seen at c. The opposite end of this lid is stifiened on its under side by a batten, 0", which closes upon a shelf, D. Furthermore, lid Gis slotted longitudinally at c, to admit free play of the vibrating lever E, the latter being pivoted at f to a bearing, F, secured upon said lid. The upper end of lever E is pierced at G G, which perforations are in line with similar holes, H H, of a supplementary lever, h,whose free end has a handle h.

g g are bolts passing through the holes GH G H, as seen in Fig. 4. The lower end of lever E has a square or other non-circular section, E, terminating with a head, 6, said section E being adapted to carry the rubber, which rubber is composed of a top board, I,

two side boards, J J, and a pair of blocks, K K. These members I, J J, and K K are so united as to form a rubber which is considerably wider at bottom than at top, the member I being pierced at 93 to permit free play of thesection E of the lever. The inner ends of blocks KK are not in contact with each other, but are separated by a chamber, L, traversed by the lever-head c, said chamber being closed at bottom by a cleat, M, uniting said blocks.

Z is a plate or cushion that may be applied to the top of chamber L.

N are holes passing through the boards J J and blocks K K.

j j are stumps or pins projecting laterally from the aforesaid boards. 7c are similar devices projecting downwardly from the blocks K K In some cases the lever E E may be made of galvanized iron or other metal that will not rust and injure the clothes; but, as a matter of economy, said lever can be composed of any cheap metal, and a guard can be attached to the rubber to prevent the articles in the tub coming in contact with said lever. As seen in Fig. 2, this guard is composed of a tube, 0, of india-rubber or other yielding material, the lower end of said tube being tacked to the board I; but in Fig. 3 this guard is composed of a galvanized-iron tube, 0, secured upon said board or upon a pierced plate, I attached to the latter, the object of this plate being to prevent the enlargement of the opening t.

R represents one of a pair of bearers attached to the opposite sides of the tub for the purpose of supporting the closed lid.

This machine is used in the following manner: Lid 0 is first opened to the position indicated by the dotted lines in Fig. 1, and after the tub has been filled with the clothes and hot suds said lid is closed to prevent the escape of vapor. If the operator wishes to sit while engaged in washing the clothes, 850., the upper bolt, g, is removed, and the supplementary lever h is swung down to the position 95 seen in Fig. 1; but if the operator desires to stand said bolt is inserted in the coincident holes G H, thereby causing said lever to serve as a vertical extension of the lever proper, E E, as represented in Fig. i. The handle h 10:

being then grasped and worked back and forth causes a corresponding vibration of the rubber I J J, whose pins jj' 7s loosen up the clothes and prevent them bunching together, while the holes N ofsaid rubber induce currents of water to flow from end to end of the tub. A s a natural result of this thorough agitation of the clothes and rapid circulation of water, the various articles are completely Washedin a few minutes and without injuring the finest fabrics, which safe action of the machine is due to the fact that the rubber is loosely hung upon the lever. Consequently said rubber will automatically rise and fall to accommodate itself to the amount of clothes in the'tulo or to any increased thickness of the garments, 820. As the clothes surge back and forth within the tub, the guard O or the guard O prevents them coming in contact with the lever E and thereby being injured by any rust on the latter.

I claim as my inventionv A washing-machine rubber consisting of the top board, I, downwardly and outwardly flaring side boards, J J, and blocks K K, said boards and blocks being perforated at N and provided, respectively, with pinsjj k, for the purpose described.

In testimony whereof I affiX my signature in presence of two witnesses.
