WASHING-MACHINE,

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed May 26,1904. Serial No- 209,837.

My invention relates to improvements in machines for-washing clothes. Its object is to provide a simple, cheap, practical, easyrunning machine which will not tear the clothes, which will have a large capacity, and which is adaptable to take a greater or less charge at one time and handle it with equal thoroughness.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a longitudinal section of ma- 'chlne.

Fig. 2 is a transverse broken section showing dasher and rubber. Fig.3 is a perspective view of bearing-plate. Fig. 4 is a perspective view of handle. Fig. 5 is a plan view of the apparatus with cover removed and a portion of the handle broken away. Fig. 6 is a plan view of the lower part of a handle, shgwing manner of connection with dasherro s. positions of a dasher at difl'erentpoints in the arc of movement of a handle.

A represents a tub of any suitable size, shape, and material. It is here shown as rectangular in form, with its bottom slightly inclined downward toward the center to a discharge-opening 2. Preferably the tub is provided with a sectional skeleton or perforated false bottom 3. A rubber 4, having a convexed corrugated working surface, is pivoted at each end of the tub, and the dasher or agitator operates intermediate of and coacts with the rubbers to squeeze and turn and cleanse the -clothes. This agitator consists of two metal arms 5, journaled in suitable bearings in' the sides of the tub and having wooden extensions connected at the top by a bar 6, forming a hand-grip, and of the two opposed concaved dasher members 7, which are pivoted to the arms and have their lower ends sliding on suitable trackways 8 on the false bottom. The dashers 7 and the rubber members 4 comprise each a pair of end castings 7 or 4, affording stepped seats for the intermediate wood slats, and each set of castings is united by suitable tie-rods 9 to form a rigid structure.

Fig. 7 is a diagrammatic view showing The rubbers 4 are pivoted at the top, as at 10, and have thin projecting guide members 11 at their lower ends operating in slots between the sides of the false bottom and the walls of the tub. These rubbers are yieldingly supported at the back by suitable means, as the springs 12, and the slats of the rubbers and of the dashers are oppositely stepped,one

up and the other down, so that a dasher and a respective rubber will cooperate as they approach and recede from each otherto squeeze and turn the interposed clothes.

The arms 5 each have their lower ends flared or widened in the direction of the length of the tub, and a pivot-pin 13 projects from one side of this flared end and a similar pin from the opposite side, the axes of the pins being parallel and on opposite sides of the longitudinal axis of the arm and spaced about three inches, more or less. i

The end castings 7 of the dashers have rearwardly extending central projections 14,

adapted to be hung on respective pins 13, the

projections 14 of one dasher engaging on the outside of the arms and those on the other dasher engaging on the inside, each dasher being connected to the pins on the arm farthest from the dasher, so that each dasher is protected against lateral movement or twist by reason of the support afforded by the wider portions of the handles against the projections 14.

The arms 5 are provided with suitable insets below their pivots 15 to accommodate those projections 14 which operate between the handles and the sides of the tub. The arms are connected below their pivots by means of the cross-bar 16, secured at its ends to the projection 17, which is integral with the handles.

By reason of the foregoing construction the cost of manufacture is greatly reduced, since the various partsto wit, the arms and the end castings 7* and 4"*are symmetrical and may be quickly assembled into a complete machine, or the essential parts of the machine may be easily knocked down for shipment.

In operation the tub being filled with water the clothes are inserted in to the space at either end between a rubber and a respective dasher. By imparting an oscillatory movement to the handles the dashers are reciprocated, alternately to approach and recede from their respective rubbers, thelatter yielding with an increase of pressure and springing out again on the retreat of the opposed dasher. The clothes are not rubbed and abraded, as in ordinary machines, but are squeezed and grad- IIO ually turned over and over. This turning is effected, first, by forming the corrugations on the respective convexed and concaved surfaces of the rubbers and dashers, so that the rubbers tend to hold the clothes against moving to the bottom of the tub, while the dashers tend rather to press the clothes on their side downward; second, by having the rubbers pivoted at one end and yieldingly supported, so that they give a limited lifting oscillating movement; third, by pivoting the dashers on the pins 13 in such fashion that while they slide back and forth on the tracks 8 they are given a limited oscillating downward movement about their lower ends as a pivot, according as the pins 13 approach or recede from the bottom of the tub in oscillating the handles. The forward movement of the rubbers about their pivots is limited by the stops 17. As it may be desired at times to wash only a few garments, or perhaps, on the other hand, .to wash an unusually large piece, as a pair of blankets, I have provided means whereby the capacity of either of the compartments between the dashers and respective rubbers may be varied. Accordingly I employ bearing-plates, as 18, adapted to be secured to the sides of the tub and having a plurality of recesses or rests 19 for the arm-pivots 15. A pivot is held in place by means of a cap-piece 20, having one end adapted to seat in a keeperQl on the top of the bearing-plate and the other end pivoted on a projection 22 intermediate of the recesses 19. proper position by means of the cover 23, which fits over the top of the tub and has recesses to receive the caps. The plates 18 are so disposed that the arms may be hung ordinarily in the middle of the tub; but if for any reason it is wanted to enlarge or restrict one or the other of the end compartments it is only necessary to turn the cap-pieces 20 on their pivots 22 to allow change of the handles, so that they journal in another set of. recesses 19, replace the cappieces, and secure them once more in position.

2 L represents splash-boards disposed horizontally above the pivoted ends of the end rubbing-surfaces to prevent the overflow of water that might otherwise follow the press The caps are normally held in ing of the rubbers against the ends of the tub by the action of the dashers and clothes.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent,

1. A washing-machine comprisinga tub, opposed rubbers at the ends of the tub, dashers intermediate of the rubbers having oppositely-disposed extending overlapping portions, and oscillating arms having flared lower ends and pivotally mounted at .an intermediate point to the tub, said arms having pintles upon which the extended portions of the dashers are pivotally connected.

2. A Washing-machine comprisingatub, opposed substantially vertical rubbers hinged at the end portions of the tub, oppositely-facing dashers located between the rubbers having oppositely -disposed extending overlapping portions, and oscillating arms having flared lower ends and pivotally mountedat an intermediate point to the tub, said arms having pintles upon which the extremities of the extended portions of the dashers are .pivotally connected, said dashers having stepped surfaces opposing corresponding surfaces on the rubbers.

8. A washing-machine comprising atub, opposedv substantially vertical rubbers in the ends of the tub said rubbers being pivoted at their upper ends and being spring-pressed at the lower portions, oppositely-facing dashers located between the rubbers having oppositely-disposed extending overlapping portions, and oscillating arms having flared lower ends and pivotally mounted at an intermediate point to the tub, said arms having pintles upon which the extremities of the extended portions of the dashers are pivotally connected, said dashers and rubbers each comprising end casting and connecting slats forming a stepped surface.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
