WASHING- MACHINE.

SPECIFICATION forming' part of Letters Patent No. 755,742, dated March 29, 1904:.A

Application filed May 2B, 1903.

To a/ZZ whom it may concern:

Be it known that I, HENRY EMIL OARsTENs, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new vand useful Improvements in Vashing-Machines, of which the following is a speciication.

This invention relates to improvements in washing-machines, and has particular reference to that class in which a rocking or swinging body and agitator are employed.

The object of the invention is to provide a washing-machine which will be simple in construction durable in use, and eiiicient in its operation and wherein the clothes are thoroughly and rapidly cleansed with the least possible amount of agitation, to the end that tearing or other injury to the fabrics is obviated and exertion on the part of the operator reduced.

Heretofore in washing-machines of this type the agitator for the clothes has been mounted so as to swing in a direction opposite to that of the body, thereby causing the same to act as a rubber and to force the clothes in a direction contrary to the movement imparted thereto by the rocking of the body. This action results in an unnecessary amount of agitation and injury to the clothes and requires considerable effort to operate the machine; but the present invention is designed to prevent these difficulties by providing means for swinging the agitator in the same direction with the body containing the clothes and accelerating the movement of the former, whereby the clothes will be carried and held by the agitator at each oscillation of the body and will act as a sieve through which the water will percolate to thoroughly clean the same, while at the same time permitting the 4clothes to gradually fall to the bottom 0f the Serial No. 158,814. (No model.)

`\washingmachine constructed in accordance with my invention. Fig. 2 is a central vertical longitudinal section showing in dotted` lines the position of the parts when the body v isswung in one direction. Fig. `3 is a perspective view of the agitator and its hangers removed from the machine. Fig. 4 is a fragmental view in vertical transverse section on the line of Fig. 1, showing thev relative `arrangement of one of the trunnions with the parts of the machine.

In the drawings similar reference-notations indicate the same parts appearing inthe several illustrations, and reference being made to the drawings, 1 designates a frame of such shape asmay be fixed upon to meet the purposes of its use. This frame comprises two pairs of legs 2 3, which are braced around the lower ends thereof by suitable stays 4, and on the upper end of each pair of legs is mounted asocketed casing or cap 5, having a transverse aperture to receive the trunnion 6, which is locked therein by means of a set-screw 7. Each of the trunnions 6 is formed at its inner end with a right-angular extension 8, from the end of 'which projects a lug or pin 9,' arranged in the plane above the portion 6, thus forming a crank-shaped member, the function for which will hereinafter be pointed out.

The body 10 of the machine consists of a semicylindrical receptacle having the usual corrugated metal lining 11 and provided on its top with a hinged cover 12. The body is further provided.with a pair of outwardlyextended arms 13, which are connected at their outer ends withva handle-bar 14, and at its opposite end there is formed a cleat 15, adapted to receive a wringer, which is not shown in the drawings. From this cleat 15 extends a downwardly-inclined drain-board 16 for conducting the water into the machine when the clothes are being wrung. The body 10 is mounted for oscillation between the legs 2 and 3 of the frame, being journaled on the trunnions 6.

On the inner side of the cover 12 are twoV pairs of ears 17, between which are pivoted the depending hangers 18 of the agitator. These hangers are bifurcated at their lower ends, as at 19, .in which bifurcation the lugs IOO 9 of the trunnions engage and slide when the body is rocked on its journal. To provide for conveniently engaging the lugs 19 in the bifurcations of the hangers, the latter are provided at their lower ends with beveled or rounded corners 20. The hangers are connected near their lower ends by a block or cross-head 21, in which is mounted the depending stem 22 of the agitator 23. This agitator is loosely mounted on the stem 22 to per-` mit it to slide verticall Y or rotate to accommodate the amount of c othes in the washingmachine, and from its bottom project the usual pins 24, which engage the clothes to hold them elevated at the endof each oscillation of the body.

From the description thus far given it will be perceived that the agitator is carried by the body and that it is permitted to swing independently of the same by means of its pivotal connection with the cover of the body; but its movements are controlled by the movements of the body, and those movements are alwaysin the same direction with the body.

As stated in the preliminary portion of the specification, the motion of the agitator is accelerated with relation to the motion of the body, and this is accomplished by the fulcrum for the agitator (Which comprises the lug 9 in the bifurcations 19) being in a plane above the fulcrum of the body, whereby when the body is rocked on its journal 6 the hangers 18are carried with it and the latter slides on the lug 9, causing the agitator to be moved faster up toward the top of the body.

Secured' at one end to one of the braces 4 is a coil-spring 25, which is engaged at its other end with the body 10 and which acts to assist the returning motion from the end of each oscillation and always causes the body to assume its normal position when left at rest'.V

To one of the legs 2 is secured a hook 26, adapted to engage an eye 27 on the side of the body when the machine is at rest and water or clothes are being introduced or removed therefrom.

The operation may be briefly stated as follows: It being premised that the required amount of clothes to be washed is contained in the body and water has been introduced, the operator rocks the body on its journal 6. Referring to Fig. 2 of the drawings, the parts are shown in dotted lines in the positions they occupy when the b'ody has been rocked in the direction of the arrow, and upon this movement the clothes, which are normally at the bottom of the body, are engaged by the pins 24 of the agitator and carried upwardly therewith, while the water will percolate through the clothes and fall to the opposite end of the body. The agitator being revoluble and slidable on the stem 22 will permit the clothes to gradually fall to the bottom of the body, so that upon the next oscillation of the latter the clothes will be again engaged by the pins tion.

and carried to the opposite end of the body, while the water willagain percolate therethrough, this operation being repeated until the clothes are thoroughly cleansed.. The accelerated movement of the agitator tends to push the clothes up against the top of the body and in a measure compressing them to rinse the water therefrom, and this continuous rinsing action hastens the washing opera- It may be further explained that the accelerated4 movement of the agitator is due to the fact that the fulcrum-lug 9 constantly changes its position in the bifurcation during the movement of the body, such change emanating from the sliding connection between the lug and the hangers, which increases the vdistance between the pivotal connection of the hangers with the cover and the lug, which is stationary. Y

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
