WASHING-MACHINE.

To all whom it may concern:

Be it known that I, ISIDOR YASSENOFF, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and use ful Improvements in Washing-Machines, of which the following is a specification.

My invention relates to improvements in washing machines which are adapted to be operated with the improved reciprocating motor shown and described in my Letters Patent of the United States, No. 894,928, and especially consists in the provision of a reciprocating or rotary device for agitating or stirring the clothing to be washed, which is adapted to be oscillated as the motor operates, especially through the action of a spring or flexible member put under tension by the operation of the motor. I have found that this construction is readily operated and is durable, and provides a washing device which is constructed at a small cost and is very durable and efficient.

Essentially it comprises a depending frame mounted loosely upon an oscillating shaft which latter carries a spring tensioning member for the purpose of giving the frame the desired degree of reciprocation. It is apparent that manually operated means may be provided instead of the motor above mentioned, and I do not confine the use of my improvements to mechanically operated machines.

In the drawings which are hereto attached and hereby made a part of this specification, Figure l is a vertical transverse section through the agitator, tub and operating means; Fig. 2 is a perspective of a modified form of agitator construction; Fig. 3 is a View of the band to which the loop or stirring members are attached, having the cross bar thereon.

Referring to the drawings in which the same numeral indicates the same part throughout, 1 indicates a tub member stationed upon the legs or base portion 2, carrying at its upper end a frame 3 forming the support for the motor 4; the cylinder is positioned by means of the set screw 5, and it should be stated that the motor is shown conventionally in the drawing.

The piston 6 is adapted to be reciprocated by fluid entering the external valve chamupon the piston rod 8, and the rack 9, the rackforming prac- Specification of Letters Patent. Application filed August 14, 1908, Serial No. 448,471.

tically an extension of the manner clearly disclosed in tioned application.

The pinion 10 is fixed on the short vertical shaft 11 which is mounted in the collar or sleeve member 12 carried by the aforesaid frame 3, the shaft being mounted in said collar for reciprocation and rack just described.

The band member 14 carries the cross bar 18 provided with a hub 13, whereby it is journaled on the shaft 11; the bar 13 is shown in Fig. 1, as formed integral with the band 14, but it is apparent that it may be formed separately and secured thereon appiston rod, in a the above menthrough the pinion,

propriately. From this band 14 there depend at desired intervals looped fingers or agitators 15, which are twisted as shown at 16 so as to bring the open side of the loop in contact with the clothing as it is swung back and forth. These loops are seen to be free at their lower ends and are securely riveted at 17 in the band 14.

Fixed upon the end of the shaft 11 is a member 18, to the opposite ends of which are attached the spring members 19 and 20 which at their other ends are secured in a desired manner to the frame or band 14 or if desired to the member 13 The shaft is oscillated under the influence of the motor; the member 18 is turned first in one direction and then in the opposite direction, thereby tensioning the springs 19 and 20 and exerting a pull thereon around a circle first in one direction and then in another, whereby an oscillating movement in a horizontal plane is imparted to the agitator 14. By these means the articles of clothing are stirred or agitated in both directions in a rapid manner and the cleansing fluid is thrown against the clothing and the clothing against the fluid and a constant agitation is thus kept up to such an extent as to cleanse the clothes very quickly. The depending agitators or fingers are so constructed as not to exert any tearing or any injurious eifect upon the fabric, and the loop formation thereof renders them readily cleansed and therefore entirely sanitary.

I have shown in the drawings and have described above, loop members or agitators 15, but I do not confine myself to this form of agitator. It should further be pointed out that in the operation of the washer, the clothing or fabric to be cleansed will be caught by the loop members and swept along thereby, in that way forming a sort of paddle to agitate the water thoroughly. I have not deemed it necessary to show a paddle construction, inasmuch as it will be readily understood.

Free space is provided between the fingers or agitators 15 and the sides and bottom of the receptacle or tub so that the clothing may be rubbed vigorously against the sides and the bottom to hasten the cleansing process. All these advantages herein set out have been demonstrated, and have been found to be of great practical value.

In Fig. 2 I have shown another form of agitator member and spring means for actuating the same, comprising an agitator member 21 mounted loosely upon the shaft 22, and having depending from its ends the stirrers 23 and 2 1, which latter may be made of any form desired. Rigidly mounted on the lower end of the shaft 22 beneath the bar member 21 is a short bar or plate 25 having extensions formed at each of its ends, which may be designated at 26 and 27 and 28 and 29. Spring members shown at 30, 31, 82 and 33 are mounted between the extensions noted and the sides of the bar member 21, which are preferably enlarged to form the shoulders shown at 34:. The springs are secured in place in any desired manner. As the shaft 22 is oscillated by the motor, the bar 25 is moved therewith thereby setting up an oscillatory movement in the agitator member 21 which is cushioned and assisted by the spring members. The form of construction shown in Fig. 2 is simpler and less expensive than that shown in Fig. 1, although it is seen that it operates in practically the same manner.

I have found the combination of my improved reciprocating motor with a stirring or agitating member by means of the springs whereby the agitator may be yieldingly oscillated in a horizontal plane to produce Very rapid .and complete results in the cleansing of any ordinary fabric; a specific form of construction is shown in the drawings and herein described but I do not desire to confine myself thereto inasmuch as modified forms of construction lie within the scope of my invention.

\Vhat I claim is:

1. A washing machine comprisingreciprocating means, a shaft actuated thereby, an

agitator rotatably borne upon said shaft, and spring means carried by said shaft for causing said agitator to assume an oscillatory mot-ion.

2. A wash ng machine comprising reciposo rocating means, a shaft adapted to be actuated thereby, an agitating member mounted loosely upon said shaft, an arm carried rigidly upon said shaftand having yielding connections with said agitating member whereby the latter is given an oscillatory motion.

3. In a washing machine including reciprocating means and a shaft adapted to be actuated thereby, an agitating member loosely.

mounted upon said shaft comprising an upper or band portion, depending loop members secured to said band portion and adapt ed to act as stirrers, an arm rigidly carried on said shaft, spring members connected to the ends of said arm and at their other ends secured to said agitating member whereby the latter is given an oscillatory motion.

1. A washing machine comprising recipocating means, a shaft actuated thereby, an so agitator rotatably mounted upon said shaft, an open looplike stirring member depending from said agitator, and yielding connections between said shaft and sa1d agitator adapted to cause the agitator to assume an oscillatory motion and also 'to cushion said agitator.

In testimony whereof I affix my signature inthe presence of two witnesses.
