WRINGER.

Specification of Letters Patent.

Application filed March 4, 1915. Serial No. 12,186.

To all whom it may concern:

Be it known that I, GEORGE W. Lnwis, a citizen of the United States, and resident of Grinnell, in the county of Poweshiek and State of Iowa, have invented a certain new and useful VVringer, of which the following is a specification.

The object of my invention is to provide a wringer especially adapted for power washing machines, of simple, durable and inexpensive construction.

A further object is to provide a wringer having a suitable supporting casing which serves as a protecting casing for the wringer parts, and also as a support for the rolls and other parts of the wringer.

Still a further object is to provide ,a wringer having means for yieldingly imposing tension upon the rolls for holding them together, and means for instantly releasing the tension device, the parts being so arranged that when the tension is released the rolls drop apart, so that not even the weight of one roll is imposedon the other roll.

Still a further object of my invention is to provide such a wringer having a tension device so constructed and arranged that parts thereof may be readily and quickly removed from the casing for repairs or replacing of parts.

Still a further object is to provide such a wringer having a tension device capable of being adjusted from outside the casing.

Still a further object is to provide such a wringer suitably adapted to support, and supporting a reversible water board.

My invention consists in the construction, combination and arrangement of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of awringer embodying my invention. Fig. 2 shows a horizontal, sectional view taken on the line 2-2 of Fig. 4. Fig. 3 shows a vertical, transverse, sectional view taken on the line 33 of Fig. 4:. Fig. 4 shows a vertical, sectional view through the casing, illustrating the manner of mounting the rolls and the tensionfdevice. Fig. 5 shows a vertical, transverse, sectional view taken on the line 55 of Fig. 4, and Fi 6 shows an end elevation of my improve wringer.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the casing in which the parts of my improved wringer are received and suptical in vertical, transverse cross-section, as will be seen from the view shown in Figs. 1 and 5.

Opposite supporting end members 11 are provided, which'end members may be cast or made of any suitable material. The members 11 fit in the opposite ends of the casing 10, and are provided with shouldlers 12 which engage the edges of said casing. The inner faces of the end members 11 are pro vided with vertical slots 13. The upper portions of said slots 13 are provided with opposite lateral extensions 14, adapted to receive the flanges of the bearing boxes 19 hereinafter described. The end members 11 are held in position by means of rods 15 extending through them. The rods 15 are provided with nuts 16, as illustrated in Figs. 1 and 6.

Mounted on the upper portion of the easing 10 is an upper wringer roll 17 which is mounted on the shaft 18. The shaft 18 extends through the right hand end member 11, and is adapted to be operatively connected with any suitable source of power.

Received within the slots or recesses 13 of the end members 11 are bearing boxes 19, adapted to receive roller bearings for the shaft 18. Below the roller 17 is a roller 20, having a shaft 21 mounted in similar bearings 19.

On the shaft 18 are gears 22 and 23 in mesh with gears 21 and 25 on the shaft 21. The water shed 26, inclined downwardly in both directions from its median line, is supported on the shaft 21 by means of arms 27, and is adapted to protect the parts below the rollers from the water dripping down from the rollers.

The following means are provided for imposing an upward yielding tension on the roller 20, for holding the rollers 17 and 20 together: Slidably mounted in the slots or openings 13 just below the lower bearings 19, are angle irons 28, adapted to reciprocate vertically in said slots. Mounted below the water shed 26 are two sleeves 2.9 and 30, one of which is telescopically received in the end of the other. Mountedin one end of the sleeve 30 is a solid body or cylinder 31. Four links 32, 33, 34c, and 35 are mounted on the cylinder 30 by the trunnions ported, which casing is substantially ellip- Patented Dec. 12, 1916..

36 on the walls of the cylinder 31. Thesite the links 32, 33,34 and 35, is a shaft or 1 rod 39, on the outer end of which is a hand wheel 40. On the rod 39 within the cylinder 30, and spaced from the body 31, is a collar 41. Mounted within the cylinder 30 on the .15 rod 39' between the collar 41 and the body 31, is a coilspring 42. In the end of the cylinder l29 opposite the cylinder 30, is a bushin 43 having a central opening in which received the sleeve 44. The sleeve 44 is provided at its inner end within the cylinder 29 with-an upwardly extending lug 45. The interior of the bushing 43 is provided at each side of the upper middle line of the opening therein, with two longitudinal grooves 46 and 47 so arranged that when the sleeve 44 is rotated to the proper point the lug 45'may be received and slide in one or the other of the grooves 46 and47.

Linkss32, 33, 34 and 35 similar to the links 32, 33,- 34 and already described, are secured to the bushing 43. The links 32 and 34 are pivotally secured to the ends 37 of the angle iron 28. The links 33 and 35 are secured by a pin 48 to the lower end of 35 the left hand end member 11. On the outer end of the sleeve 44 is a handle 49. A part of the rod 39 is screw threaded at 50, and is received within the screw threaded portion of the sleeve 44. y 40 Below the casing 10 is a reversible water board 51 having u turned ends 52 pivoted to the members 11. lhe casing 10 is provided with opposite slots 53 foradmitting material to the rollers 17 and 20. The lower end of the casing is open at 54 to allow water to pass out.

In the practical use of my improved wringer it is mounted upon a tub or washing machine in any suitable way, and may be used either as-a swinging wring r or as a stationary wringer, depending upon the method of mounting employed. The parts having been assembled, the hand wheel 40 may be rotated to compress the spring 42 55 for imposing any desired tension on the rollers. If the fingers of the operator or any delicate fabric should be caught in the rollers, or if the fabric should become wound on one of the rollers, the tension may be instantlyreleased by moving the handle 49 in either direction. The lug 45 v will then enter one of the slots 46 or 47, whereupon the spring will force the sleeve 44 and the rod 39 longitudinally outwardly, thereby rerleasing the tension" on the rollers and per- -29 and 30.

mitting the lower roller to ,drop away from the upper roller. The rod 39 may then be secured upwardly and pushed back to position and the handle 49 moved to upright position, whereupon the hand wheel 40 may be rotated for again imposing proper tension on the rollers.

With a wringer of this kind all the moving parts except small portions of the rollers, are protected by the casing so that there is no danger of catching the fingers of the operator or parts of the material passing through the wringer, in the cogs or other mechanism.

It will readily be seen that one end of the device can be placed in position, and that the mechanism can then be assembled and inserted into the casing from the other end, and the bolts or pins 38 and 48 may be secured in position and the rods 15 assembled, so that the assembling of the wringer is easily and quickly accomplished.

The tension of the rollers is imposed from below. With the ordinary wringer'tension is imposed ,fromabove, so that even if there is a releasing device, it only releases the spring tension and leaves the weight of one roller imposed on the other. With my wringer the release of the tension permits the lower roller to drop away from the upper roller entirely.

The tension imposing mechanism is entirely protected from water by means of the water shed device 26, and telescoping tubes The device when completed. may be easily handled as a unit, and has a good appearance.

It will be understood that changes may a be made in the details of the construction of my improved wringer without departing from its essential features and purposes, and it is my intent to cover by this application any such changes which may be included within the scope of my claims.
