SPECIFICATION rei-:ning part of Letters Patent No. 315,812, dated April 14, 1885.

Application filed March 2:2, 1884. (No model.)

To all whom t may concern.'

Be it known that I, JOHN E. MITCHELL, of Keokuk, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in Tashing-Machines; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to washi11g-machines, and more particularly to certain improvements on the machine patented to nic July l0, issn, No. 281,111.

The object of the present invention is to provide a machine of simple and durable construction, and one that will avoid the inconveniences incident to the use of my former machine.

The invention consists in the novel means for liinging the crossbar of the machine to i's standrrd, in a novel automatic securing device for said cross-bar; in an improved form of rubber shaft and crank; in means for securing and operating the lever of the machine, and in various other features of construction, as will be fully described hereinafter, and pointed out in the claims.

In the drawings, Figure 1 is a plan. view of my improved machine. Fig. 2 is a side view of the same. Fi g. 3 is avertieal section. Fig. 4 iilustrates the false bottom of the tub and the face ofthe oscillating rubber; and Figs. 5, 6, and 7 are sectional detail views.

A A represent parallel standards secured to base-blocks ac and connected by a crossbar, b. This bar b is provided centrally with a socket, Cwhich receives a tal'nering pivot, C2, secured rigidly to the center of an oscillating frame, C', upon which the tub C is removably secured.

D represents a removable or false bottom secured within the tub by means of a tongue, (P, and staple d, and a staple, d, and crosspin d?.

E represents a cross-bar pivotally secured to the upper end of the standard A by means of arms e e, secured to the sides of the standard by a pin, c', passing through the arms and standard. The opposite end of the cross-bar E rests upon abracket, F, projecting from a drip-pan, II, secured to the inner side of the upper end of the standard B. A. ring, G, iits upon the end of the crossbar and is secured thereto by alnop-pin, g. This ringG is drawn inwardly to release the cross-bar from its engagement with the bracket F, and to secure the bar it is onlyT necessary to drop the bar upon the bracket (holding the ring up against the under side of the bar) and allow the ring by its own weight to i'all and embrace the bracket. The drip-pan I-I is made ot' metal, to insure durability, and is designed to carry the water from a wringer arranged above the tub back into the latter. The bar Eis provided at its center with an opening` to receive a anged siceve, I. XVitliin this sleeve is secured abearing-sleeve, J, projecting from a crank-arm, K, and secured by a cross-pin, j. The sleeve-bearing .I is of square or equivalent forinin cross-section to receive the shaft L of the rubber M. This shaft L corresponds in cross-section to the siccve-bearing J, thus allowing` the rubber to be raised and lowered freely. Both the false bottoni D and the under surface ofthe rubber are each provided with two series or" slats, arranged at right angles to veach other. The slats d of the false bottom are secured at right angles to the slats d', and the slats m of the rubber are at right angles to the slats m. slats eifects a thorough agitation of the water in the tub. The tub and rubber (as will be explained) oscillate in opposite directions, so that the slats of the false bottom will force the water in currents to the center, and at the same time the rubber slats (moving in the op` posite direction) will tend to force the water to the outer edges of the tub. The constant This arrangement of 8o reversal of the movements of the rubber and tub effects a continual reversal of the currents of Water, thus insuring the maximum agitation, and lessening materially the time and labor required to cleanse the clothes.

I represents an arm or bracket secured to the standard A by means of a prong, 1J, entering the standard, and a bolt, p', passing through the standard and bracket and held by a nut. The outer end of the bracket P is ofjournal form and receives a iianged sleeve, Q, which enters an opcningiuthelever O and is held by a pin, Q.

N is a rod connecting the lower end of the lever O with the oscillating frame C', upon which the tub is secured.

IOO

R is a similar rod connecting the outer end of the crank-arm K with the lever O above the center of the latter.

O represents a treadle projecting from the 5 lower end of the lever to admit of the application of foot-power as an auxiliary to handpower in operating the lever.

It will be apparent from the above descrip- Y tion that when the lever is operated the tub 1o and rubber Will be oscillated in opposite directions. The arms e e enable the cross-bar E to be raised to remove the rubber from the tub Without contact with the drip-pan H. The rubber, by means of the construction of the shaft 1 5 L' and its adjacent parts, may be readily raised and lowered. The lever O is securely held upon the standard A, and an automatic securing device for the bar E is provided.

Having .fully described my invention, what 2o I claim as new, and desire to secure by Letters Patent, isn

lng Witnesses.

1. The combination, with the standards, of a hinged cross-bar and a supporting-bracket, Which latter receives the free end of the crossbar, and a ring arranged upon said cross-bar 25 to engage the bracket, substantially as set forth. I

2. The combination, with the standards A and B, of a cross-bar hinged to the standard A by arme e e below the top edge of the tub, 3o a. bracket projecting from the standard B, and a ring pivotally secured upon --the crossbar to engage said bracket, substantially as set forth.

In testimony whereof I have signed this 35 specification in the presence of tWo subscrib- JOHN E. MITCHELL.
