JOHN W. MULLINS, OFLONDON, KENTUCKY.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 412,403, dated October 8, 1889.

' Application filed May 17, 1889. Serial No. 311,118. (No model.)

To all whom it may concern.-

Be it. known that I, JOHN W. MULLINS, a citizen of the United States, residing at London, in the county of Laurel, State of Ken tucky, have invented certain new and useful Improvements in Washing Machines, of

which the following is a specification, refer tub to present difierent portions of the clothing to the action of the pounder.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a washingmachine constructed in accordance with my invention,

the tub thereof being shown in central vertical section. Fig. 2 is a plan of the same, the tub and its ratchet being shown in dotted lines; and Fig. 3 is a bottom view of the head of the pounder. I

Like letters of reference refer to like parts in all the figures of the drawings.

A is a beam of a desired length and form, which is cut out on its under surface, and the cross-piece A secured therein by screws or.

other fastenings, the beam A and cross-piece A forming a suitable base for the machine. Projecting upwardly and suitably secured to the beam A is the upright or standard A On the upper surface of the beam A is fixed the stud or pivot A B is a tub of any ordinary well-known construction, to the outer surface of the bottom of which is attached the ratchet B, provided with any desired number of teeth. The ratchet B is perforated at its center, the perforation serving as a bearing for the pivot or stud A Passing through a perforation formed in the upright A is the shaft 0, which bears freely therein. Bigidly secured to one end of the shaft is the arm 0, to the end of which is pivoted the pawl 0 the pivot being shown at C The pawl O is bent, as at 0 to engage with the teeth of the ratchet B of the tub B, thereby serving to rotate the tub. The pawl O is allowed to be pressed outwardly by the teeth of the ratchet as the staple G which is suitably secured in place on the side of the beam A, is lengthened for this purpose. (See dotted lines, Fig. 2.) i

D is an arm, which is rigidly secured to the shaft C and extends through or may be otherwise connected to the pounder E, and is held in place by the pin, E. The pounder E has a suitable handle, as E by which it can be operated, and terminates in an enlarged head. On the under surface of theenlarged head of the pounder there is secured the preferably-galvanized wire F, whichis formed in a succession of S-shaped convolutions arranged in a common plane, the pounder being thus made open for the passage of water therethrough; or the convolutions may be of any other suitable material that will not injure the clothing while being pounded.

The-operation of the invention is as follows: Olothin g and water sufficient to cover the same are placed in the tub. The handle of the pounder is then oscillated at the same time the pounder-head is pounding the clothing. When the lever is oscillated, it necessarily imparts motion to the arm D, shaft 0, arm 0 and pawl 0 So long as the pawl travels between two teeth of the ratchet the tub will not be rotated; but when. the stroke of the lever is lengthened until it takes the position shown by dotted lines in Fig. 1 the tub will be rotated one or more teeth, in accordance with the power applied. When the pawl is retracted from the position shown by dotted lines, Fig. 1, to the position shown by full lines in said figure, said pawl is forced outwardly in the staple by the curvature of the teeth of the ratchet to the position shown by dotted lines in Fig. 2. By lengthening the staple this outward movement of the pawl is permitted.

What I claim is- 1. The combination, with a base having a pivot and an upright, of a tub having a ratchet bearing on said pivot, arms pivoted to the one end, and its other end, after passing through a keeper on the base, turned up to form a vertical portion to engage the ratchet, substantially as specified.

2. The combination of the base provided With a pivot and standard, a pounding lever pivotally connected to a curved arm, a straight arm, a pivot or shaft common to both arms and rigidly connected with the same, a pawl pivoted to the straight arm and mounted in a staple constructed to permit lateral move- 10 ment therein of the pawl, and the tub provided with the ratchet, substantially as specified.

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

JOHN WV. MULLINS. Witnesses:

C. B. FARIs, J. C. JOHNSON.
