I 1 IE- FRANK DUMAS, OF BURKE, NEW YORK.

WASHING-MACHINE.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed May 6, 1913. Serial No. 765,896.

To all whom it may concern Be it known that I, FRANK DUMAS, residing at Burke, in the county of Franklin and State of New York, have invented a new and Improved lVashing-Machine, of which the following is a specification.

My invention is an improved washing machine of the rotary agitator type, and my invention primarily has for its purpose to provide a machine of the general character stated of a simple and economical constructlon and 18 especially designed to adapt 1t for washing all kinds of fabrics in a quick and efficient manner and with little or no danger of injury thereto.

With other objects in view my invention provides an improved construct-ion of washing machine in which is included a reversely rotatable agitator, and means for actuating the same, in the nature of a gear segment that engages a gear on the agitator shaft and formed with an oscillatory hand lever and spring mechanism that assists in throwing the lever as it is oscillated and which acts as a tension means for holding the said lever against excessive movement in either direction as it is moved by hand.

My invention also provides an improved means for confining the fabrics being washed.

to such conditions within the tub for facilitating the beater action of the agitator and for holding the fabric from choking against the top of the washer.

In its more subordinate nature, my invention consists in certain details of construction and novel arrangement of parts all of which will be hereinafter fully explained, specifically pointed out in the appended claim, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my improved washing machine. Fig. 2 is a vertical section thereof. Fig. 3 is a perspective view of the same, the cover and the agitator or beater being shown raised, a slightly modified arrangement of the lever springs being also shown. Fig. t is a plan view of the machine shown in Fig. 3, the top being down.

The practical arrangement of my improved washing machine consists of a body or tub 1, preferably tapering in shape, whose inner face is smooth throughout. At the rear edge the tub has a fixedly held, cover plate 2 to the lower side of which is secured a cross cleat 3, the purpose of which will presently appear.

a designates a cover or lid and it is connected by the hinges 55 with the cover piece 2 to swing up toward the said piece 2 in the manner clearly shown in Fig. 8, whereby to lift the rotary beater or agitator 6 entirely off the tub when it is desired to put in or take out of the tub the material to be washed.

The agitator or heater 6 in my improved washing machine comprises a hub 60, pendentfrom the lid 4, it being of a length to extend approximately two-thirds down into the tub, whereby to leave the bottom part of the tub free for receiving and for agitating the fabrics to be cleaned. The beater 6 also includes a series of fingers 61 that project laterally from the hub and these are of uniform length and extend but partially across the tub, to leave free space at the inner sides of the tub from the top to the bottom for the purpose presently explained. The shaft 63 of the beater or agitator, extends up through a bearing 64 in the hinged top, and it is keyed to a segment gear 7 that rotates with the shaft 63 and it is held to be oscillated on 'the ball bearings 65 (see Fig. 2). The

upper end of the shaft 63 is journaled in a bridge bracket 8 that is mounted upon the top or cover.

9 designates, what I term the actuating lever, since the oscillation of the lever actuates the beater 6. and the said lever swings in a horizontal plane above the top of the washer. At the inner end the lever 9 carries a segment gear 92 that meshes with the segment gear 7 on the beater shaft, it being apparent by referring to the drawings, that by swinging the lever 9 in opposite directions, a reverse rotary motion is imparted to the beater or agitator. Lever 9 is fulcrumed on a stud bolt 8 secured to the hinged cover and for limiting the throw of the lever, in either direction, and for providing a spring power that assists in swinging the said lever in its opposite movement, the said lever is connected to a stout steel spring bar 10 the lower endof which is bolted to the outside of the tub and the upper end is passed through an elongated slot 93 in the lever.

11 designates a. supplemental spring device and the same may be a single coiled spring that extends entirely around the upper end of the tub and is fastened thereto by a screw 13, as shown in Fig. 2, and the opposite ends thereof connected to the spring bar 10, or it may be two short coiled springs 1212 connected to the said bar 10 and the tub, as shown in Figs. 3 and 4. By connecting the coiled spring device to the bar 10, as shown, any tendency to put an excessive strain on the bar 10, as it is bent over in the opposite directions is overcome by the tension of the coiled springs, which tension, as the lever is started in an opposite direction together with the tension of the spring bar 10, tends to materially aid in moving the lever 10 in the said opposite direction.

The hinged lid or cover 4 does not extend entirely across the top of the tub, and by reason thereof a space 15 is provided, at one side of the tub, that is closed at the bottom by a supplemental top or cover piece 16.

located at right angles to the cross cleat 3 on which the stationary cover piece 2 is mounted. By forming the cover in the manner stated provision is made for readily pulling out the clothes over the member 16 when the coVer is raised, as in Fig. 3.

By reason of arranging the members 3 and 16, as stated, the clothes as they are agitated by the beater are caused to engage the said members 3 and 16 and be thereby constantly directed toward the lower part of the tub, and as they are thrown up (see arrow it) toward the cover, they are caused to engage the cleats 3 and 16 to be again deflected onto the beater members after creating a thorough sousing or agitating of the material being washed.

20 designates a latch device of any approved form for holding the hinged cover tightly on the top of the-tub.

Another advantage in making the hinged lid to cover but a part of the top of the tub and placing the supplemental member 16 as stated and shown, is that provision is made for pouring the washing fluid or adding to the fluid contained in the tub by pouring onto the member 16, from whence it passes under the lid into the tub and thereby saves necessity of raising the cover and its attached parts for pouring in the solution.

WVhat I claim is:

A washing machine comprising a tub, a hinged top therefor, a rotary beater mounted on the top, an actuating lever also mounted on the top operatively connected with the beater, said lever including a handle projected beyond the top and horizontally swingable relatively to the said top, a tension device mounted on the tub with which the said handle engages when the top is down, and which operates to limit the swingable movements of the said handle, the said handle having a longitudinal slot, the said tension device consisting of a resilient member whose free end projects upwardly and is held to extend into the slot of the handle when the latter is swung down, and supplemental tension members that connect with the resilient member at each side there of, said supplemental tension members being secured to the body of the tub and disposed at right angles to the resilient member.
