WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 712,427,- dated October `28, 1902.

` Application filed August 21,' 19(11. Serial No. 72,843. (Model.)

To alt whom t may concern: ,j

Be it known that I, OOURTNEY WARREN, a

1 citizen of the United States, residing at B uda,`

in the county of Bureau and State of Illinois, have invented a new and useful Washing-Machine, of which the following is a speciica-- tion. t

The invention relates to improvements in Washing-machines.

The object of `the present invention is to improve the construction of washing machines and to provide a simple and comparatively inexpensive one capable of rapidly and thoroughly washing clothes and other fabrics without tearing or otherwise injuring the same.

A further object of the invention is to improve the construction of that class of washingmachines having a rotary rubber and presser adapted to squeeze the clothes between it and the sides of the washing-machinevbody and to provide means for reversely rotating the rubber and presser on its axis.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a vertical sectional view of a washingmachine constructed in accordance with this invention. ahorizontal sectional viewof the same. Fig. 3 is a plan view. Fig. 4 is an enlarged detail sectional View illustrating the arrange` ment of the gearing for reversely rotating the rotary presser.

Like numerals of reference designate corresponding parts in all the figures of the drawings. 4

1 designates a tapering washing-machine body or tub supported by legs 2 and provided with sides 3, circular in cross-section and converging toward the top ofA the tub or body. The sides of the washing-machine body or tub are corrugated to form inner rubbingsurfaces 4 for engaging the clothes or other fabrics being washed and forcoperating with a rotary presser 5, mounted on a vertical portion 6 of a crank-shaft 7, and adapted when the machine is operated, as hereinafter described, to rotate on its axis and revolve Fig. 2 is` around the bearings of the crank-shaft, whereby the clothes and other fabrics within the washing-machine are pressed and rubbed between it and the sides of the tub without tearing the fabrics or twisting or dragging the `Same around the tub.

The crank-shaft is provided with a lower horizontal arm 8, terminating in a journal 9, which is stepped in a suitable bearing of the bottom of the washing-machine tub or body. The upper arm 10. of theV crank-shaft is located a short distance above the rotary presser and is provided with an upwardly-extending journal arranged in a suitable bearing of a support 12. The support 12 consists of a hori- 1 zontal bar 13, of wood or other suitable material, and a metal frame 111, secured to the upper face of the bar 13and forming a bearing-bracket for supporting a horizontal shaft 15. The horizontal bar 13 extends from one side of the washing-.machine body to a point slightly beyond the center thereof, and the kbearing bracket or frame 14 is provided with inner and outer arms 16 and 17, having bearings for the said shaft 15. The bracket is bolted or otherwise secured to the upper face of the bar 13,'and it is hinged at its outer end at 18 to a leaf or plate 19, which is secured to the exterior of thewashing-machine body, as clearly shown in Fig. 1. `The hinge-joint permits the rotary rubber and presser to be swung upward out of the washing-machine body. The Washing-machine body is provided with a cover 2l, having'a slot or opening 22 toen- Ipletes the cover when the parts are arranged as shown in Fig. 3Q

The rotary presser, which is of conical form, is composed of a supporting-frame and inclined tapering Mllsre and in practice is designed to operate close to the sides of the washingmachine body. The supportingframe consists of a circular base 25 and a circular top 26, suitably connected with the oircular base. The circularvbase is provided at its lower facewith a circular recess for the reception of the lower arm of the cran k-shaft, and this recess enables the base of the rotary presser to operate close to the bottom of the washing-machine body. The inclined rolls 24, which may be journaled in suitable bearing-openings of the circular base and the cir- IOO cular top, are provided with Iiuted or corrugated faces, and when the crank-shaft is rotated the rotary presser revolves around the bearings of the crank-shaft, the clothes and other fabrics being squeezed between the presser and the washing-machine body. The crank and horizontal shafts are connected at their adjacent ends by bevel or other suitable gearing, and the horizontal shaft is provided at its outer end with a crank-handle 35, by means of which the machine is operated.

As the rotary presser revolves around the center of the washing-machine body or tub it is reversely or rearwardly rotated on its axis to enable it to press the clothes and other fabrics against the'sidesof the washing-machine body or tub `to expel the water from the fabrics and thereby wash the same without injuring the fabrics and without causing long pieces, such as sheets and the like, to twist in the washing-machine orbe dragged around the same. This retrograde rotation of the presser also reduces the resistance to the forward bodily. movement of the same to a minimum and enables the washing-machine to be operated atthe expense ofaminimumamount of power. y

The circular top of the frame of the rotary presser is provided with internal spur-teeth 36, which mesh with an eccentrically-mounted gear-wheel 37, having a pinion 3S fixed to it, and this pinion meshes with a central gear-wheel 39, which is fixed to the vertical portion 6 of the crank-shaft. The gear-wheel 37 is mounted on a suitable journal or pin 40 of a circular plate 4l and is detachably secured to the said pin or journal by means of a split key. The circular top of the presserframe is dished, as shown, and extends in" ward and downward from the internal gear formed by the teeth 3G, and the circularplate, which is arranged within the circular top of the frame, is supported on the shaft 7 between a lower collar 42 and the central gear-wheel 39. The circular plate 39 is loose on the vertical portion of the crank-shaft, and it is yieldingly held in a relatively fixed position by means of springs 43, arranged in pairs and connected at their inner ends to inclined arms 44 of the circular plate and at their outer ends to the sides of the washing-machine body. The outer ends of the springs, which are disposed approximately horizontal, are preferably attached to plates or bars 45, which are detachably secured to the sides of the body by screws or any other suitable fastening means. The arms 44 extend outward beyond the circular plate, and the springs at the same side of the presser diverge outward slightly when the parts are arranged as shown in Fig; 2. The springs are adapted to permit the presser to revolve around the center of the washing-machine body, and they maintain the circular plate in an approximately relative fixed position to cause the gearing to rotate the presser on its axis. This reverse rotary movement of the presser enables the clothes and other fabrics being Washed to be operated on with a minimum resistance, thereby facilitating the operation of the washingmachine and at the same time preventing injury to the fabric.

What I claim isl. In a washing-machine, the combination 'of a body, a presser arranged within the body, means for moving the presser bodily in a circular path within the washing-machine body, and means for yieldingly rotating the presser on its axis, substantially as described.

2. In a washing-machine, the combination of a body, a crank-shaft, a rotary presser mounted on the crank-shaft, and means for yieldingly rotating the presser on its axis, substantially as described.

3. In a washing-machine, the combination o f a body, a crank-shaft, a rotary presser mounted on the crankshaft and arranged to revolve around the bearings of the crank,- shaft, gearing connecting the rotary presser with the shaft, whereby the presser is rotated on its axis, and springs connected with the rotary presser, substantially as described.

4. In a washing-machine, the combination of a body, a shaft, a rotary presser mounted ou the' shaft and arranged to revolve around the bearings of the same, said presser being provided with an internal gear, a plate loosely mounted on the shaft, a gear mounted on the plate and meshing with the internal gear Vof the presser, gearing connectingv the gear ot' t-he plate with the shaft, and means for yieldingly holding the plate against rotation in the body, substantially as described.

5. In a washing-machine, the combination of a body, a crank-shaft, a rotary presser mounted on the crank-shaft and having a gear, a gear fixed to the-shaft, a plate loosely mounted on the shaft, gears carried by the said plate and meshing with the said gears, and springs connecting the plate with the body, substantially as described.

6. In a washing-machine, the combination of a body, a crank-shaft, a rotary presser mounted on the crank-shaft and having a gear, a gear fixed to the shaft, a plate loosely' mounted on the shaft, gears carried bythe said plate and meshing with the said gears, arms extending from the plate, and springs arranged in pairs and connected with the arms and with the body, substantially as described. Y

In testimony that I claim the foregoing as my own I have hereto axed my signature in the presence of two witnesses.
