AUGUSTUS LIESE, OF SOUTH LANCASTER, MASSACHUSETTS.

WRINGER.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application 'lled September 18,u 1907. Serial No. 393,527.

To all whom it may concern:

Be it known that I, AUGUSTUS LiEsE, a citizen of the United States, residing at South Lancaster, in the county of Worcester and State of Massachusetts, have invented a new and useful Wringer, of which the following is a specication.

This invention relates to a clothes Wringer, the principal objects being to provide a construction in which a multi lication of power can be secured in a simp e and convenient manner at the same time inclosing all the gearing so that it may not roject in a osition where it can catch in t e clothing o the operator or inarticles passing through the wringer to provide means whereby one of the rolls may move away from the other when heavy piecesare passed through the wringer without interfering with the positive and constant transmission of power to both rolls; to rovide means for positively driving both rol s at a constant speed irrespective of the relative positions; to provide an improved form of spring, pressing one roll toward the other to provide improved means for directingthe water vfrom the wringer to the tubs, facilitating changing the direction of the dri ,pings from one tub to the other to providIe improved means for fastening the wringer on the tubs 5 and generally to simplify., and improve the construction of wringers.

Further objects and advantages of the ini vention will appear hereinafter.

Reference is to be had to the accompanying drawingsl which show a preferred form of the invention ,3 and in which Figure 1 is a front elevation of the same with parts in section. Fig. 2 is an end view. Fig. 3 is a'A transverse sectional view through the center, and Fig. 4 is a view of the-end of the machine opposite to that shownjin-Fig. 2.

The wringer is shown as comprising a frame 10 having a downwardly extending projection 11 integral with each side of the frame. This arm is designjed to be set up against the edge of a tub A or the like, and

the frame is intended to 'be secured in position thereon by means of a clamping member 12 which is rovided with a rojection 13, on the top o whichjis a partial nut 14. Over this nut extends a hood 15 having a slanting upper surface.

Mounted in bearing plates 16 on the opposite ends of the frame is a screw 17 which is free to rotate but not to move longitudinally. This screw meshes with the partial nut and is designed to move the nut and the clamping piece 12 back and forth. It will be observed that the screw not only bears on its lower side in the nut, but also bears on the lower edge of the inclined hood 15. This forms sufficient bearing to permit the turning of the screw to give a positive motion to the clamping piece, and yet when it is desired to move the clamping piece along the screw quickly, it is necessary merely to turn the same at an angle so that the nut will be moved out ofengagement with the screw and the hood can be moved along the screw at will. This forms a positive clamping arrangement which can be thrown out of mesh and moved freely and rapidly from one end of the screw to the other as desired. The screw may be provided with any desired kind of an operating handle or the like 18.

The frame 10 may be made of wood or any desired material and is provided with vertical front and rear lates 20, at the to of which are slanting eflecting plates 21 w ich cover the lower part of the frame and terminate in close proximity to the lower wringing roll 22, so that the water from the clothing will flow over the top of one of the plates 21 into the tub. The water that passes between the rolls and these plates is intended to be intercepted by a plate 23 which'is adjustable to direct the water in either direction so that it may flow into either one of the tubs. In the construction shown this, result is obtained by means of a pair of;,depending links 24 suspended from pivots directly under the lower roll, and to which the upper part of the plate 23 is pivoted. Two pairs of springs 25 are mounted on the inside ofthe end ieces of the frame to hold the plate in the fu l line or dotted line position La's'indicated in Fig. 3 so as to direct the water in either direction.

Y Above the plates 21 the frame is provided with a pair of guard plates 30 having ilanges 31 on their front and'rear edges extending inwardly. These plates are provided with perforations for receiving the spindles 32 of the roller\ 22 and with slots 33 for receiving the spindles 34 of the upper roll 35, to permit the upper roll to move vertically. It will be seen that the flanges 31 extend inwardly in such position as to prevent articles passing through the wringer from being drawn toward the ends of the rolls and coming into the space between them and the sides of the frame. The side plates 30 are also provided with larger slots 36 above the slots 33 for rei-.

ceiving the ends of the springs for holding the upper roll yieldingly 1n position against the lower roll. These springs are shown as consisting of three pieces of resilient metal numbered respectively 40, 41 and 42. The spring 40 is bowed downwardly in the center, and its ends 43 extend into slots 44 in the end pieces of the frame and bear against the top piece 45 of the frame. The spring 41 is bowed upwardly at the center engaging the lower bowed portion of the spring 40. Its ends 46 are similar to the ends 43, but are at the bottom of the spring 41. These ends are also in the slots 44 and bear on the ends 47 of the spring 42 which is shown as lighter than the other two springs. It is bowed upwardly at the center, but not to suoli a degree as the spring 41. The ends 47 rest on blocks 48 which reciprocate in the end frames. These three s rings are connected by a pin 49 which is firm y secured to the lower spring and passes freely through a hole in the centers of the springs 40 and 41. The upper end of this in is fixed in the top cross-bar 45.

It wil be seen that the spring 42 having the center of its upper bowed portion fixed in osition by the rod 49 acts independent y to press against the blocks 4S and hold the same down, while the ends 46 of the spring 41 co-act with the spring 40 to assist in accomplishing the same purpose, the springs 40 and 41 being supported by the ends 47. It will be understood that the blocks rest on bushings 50 carried by the spindle 34 and rise and fall with the roll 35, t ie springs operating to hold the roll down. The downward motion of the ends of the springs is limited by projections or shoulders 470 on the guards 30, so as to revent excessive pressure on the lower rolll.)

The spindle 32 is mounted to turn in antifriction bearings shown in the present instance as consisting of rollers 51 which are mounted in the casing 52. This casing is provided with a cover plate 53 which in turn is covered by a plate 54 on one end of the machine. On the other end of the machine the corresponding plate 53 is covered by a larger plate 55 which is preferably substantially circular in form, and is xed to the end of the frame so as to be able to support the operating mechanism which will now be described. The spindle 32 at this end of the machine extends through the plate 55 and has a pinion or gear 60 thereon. The plate 55 also has a slot 61 therein through which projects the spindle 34 at this side of the machine, which spindle is also provided with a pinion or gear 62. 1t, of course, being understood that the upper roll has vertical motion, it will be seen that this gear or pinion also will move vertically when the article to be wrung is especially thick orheavy. In

order that these two pinions may be driven constantly and uniformly independently of the position of the upper roller, the following mechanism is provided.

Pivotally mounted on the spindle 34 are a pair of frames 64 each having` a slight oscil lating motion. Each of these frames has bearings in which are mounted gears 65. As these frames swing about the axis of the u per roll, it is obvious that the gear 65 may e made of such size as always to mesh with the pinion 62 whatever the position of the frames 64. 1n order to drive the gears an outside plate 66 is mounted over the plate 55 so as to cover the mechanism thereon, this plate being held in position by screws 67 passing from the end piece of the frame through both plates, and having nuts thereon for fixing the outer plate in position. This outer plate has flanges 68 for engagement with the plate 55 to define and limit its position, and it is provided with a stud 70 on which is rotatably mounted an internal gear wheel 71. The stud, of course, is concentric with the roll 35 when in its lowest position. The gear wheel is provided with a handle 72, and when rotated its teeth constantly mesh with the pinion 60 and also with both of the gears 65 independently of their position.

The rise oi the upper roll will raise the pivot on which the frames 64 swing. In order to provide for forcing the two gears outwardly to keep them in mesh with the teeth of the internal gear wheel, a spring 73 is mounted above the two frames 64 and formed into a bow-shape so as to yieldingly force them away from each other. It will be observed also that the end of the spring 42 projects through the slots 44 and 36, and that the frames 64 have upwardly extending projections 74 which engage the projecting end of the spring 42 so as to prevent the frames from rising above a certain point. lt will also be observed that these frames have outwardly extending projections 75 at their lower ends which bear on lugs 76 on the inside of the frame 66, and on the outside of plate 55 so as to limit the motion in that direction. It will be seen, therefore, that the frames 64 while free to have a certain motion, are constrained to move within certain limits so that the pinions which they carry will always remain in mesh with the internal gear wheel, and that the rotation of the same independently of the position of the upper roll will be transmitted at all times to both of the rolls to rotate them constantly at the same speed.
