WRINGER.

Application led May 20, 1921.

T o all whom t may concern Be it known that I, EDGAR D. M1sNnRa citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented cer faces terminating in off-set steps for cooperating with the rotatable tensioning mem ber to move the movable roll of the wringer toward the other upon rotation of the tensioning member and to hold the same in either of its adjusted positions. The invention has for another object, the provision of equalizing means for facilitating the simultaneous and equal movements of the opposite ends of the movable roll when moving away from the other roll. Further objects of the invention reside in the novel features of construction as more fully hereinafter set forth.

In the drawings:

Figure 1 is a side elevation partly broken away and in section, of a wringer 4embodying my invention;

Figure 2 is a top plan view thereof;

Figure 3 is a cross section on the'line 3-3 of Figure 1;

Figure 4 is a bottom plan View of the stepped cam member;

Figure 5 is a cross section on the line 5--5 of Figure 2.

l is the frame of the wringer formed of the complementary sections 2 and 3 which are suitably secured to each other as by means of the machine screws 4. 5 is the power driven roll and 6 the cooperating roll. The shaft 7 of the power driven roll is rotatably mounted in bearing blocks 8 at its opposite ends which are positioned between the complementary sections 2 and 3. 9 is a gear secured to one end of the shaft 7 and adapt- Serial No. 471,136.

ed to mesh with the gear 10 secured to the corresponding end of the shaft 11 of the cooperating roll, these two gears being inclosed within the enlargement 12 formed upon the complementary sections 2 and 3. 13 are bearing blocks located at the opposite ends of the shaft 11 and slidably engaging between -the complementary sections 2 and 3 of the frame.

The bearing blocks 8 and 13 are preferably formed of wood and impregnated with lubricant, each having the half bearing 14 for engagement with the shafts.

15 is a resilient bowed member extending above the cooperating roll 6 and having its ends engaging in rectangular apertures 16 in the upper end of the metal strips 17 which are at the inner sidesof the bearing blocks 13 and have circular openings 18 near their lower ends for engagement with the shaft 11, these circular apertures being of suffi-- cient diameter so that when the cooperating roll 6 is moved toward the power driven roll 5 by means of the ends of the resilient bowed member contacting with the t"ops of the bearing blocks 13, the shaft 11 will contact with the half bearings in the bearing blocks 13. 19 is a tensioning rod extending transversely of the resilient bowed member 15 and longitudinally movable in the cam member 20 secured centrally to the top ofthe frame 1. This tensioning rod is secured at its lower endlto the clip 21 by means of the screw 22 threadedly engaging the clip and extending into the annular groove 23 in the tensioning rod. The lower portion of the clip is U-shaped to embrace the center of the resilient bowed member 15. l

. For the purpose of facilitating the movement of the cooperating roll 6 toward the power driven roll 5, the cam member 20 has the pairs of cam or inclined faces 24 and 25 at the lower ends of which are the shoulders or steps 26 and 27 respectively, and the tensioning rod 19 has the transverse projection 28, which is preferably a pin, extending out from one side thereof for engagement with these inclined faces and st ps, the particular face and step being depen ent upon the direction of the rotation of the tensioning rod. The transverse pin 28 is normally between the upper ends of the inclined faces when there is no tension upon the resilient bowed member-15 so that this pin is in position to engage the inclined faces and to ride down over the same upon rotation of the tensioning rod to place the resilient bowed member under tension and to move' the cooperating roll 6 toward the power driven roll 5 by means of the bearing blocks 13. The steps 26 and 27 are at different heights so that a differentv predetermined tension is placed upon the resilient bowed member when the transverse pin is in engagement with each of these steps.

To release the pressure of thecooperating roll upon the power driven roll it is merely necessary to rotate the tensioning rod 19 to disengage its transverse pin 28 from its engaged step, when the pin will ride up over an inclined face. The handle 29 is provided at the upper end of the tensioning rod for rotating the same to move the cooperating roll 6 toward the power driven roll or for disengaging the transverse pin from its engaged step and to prevent vrotation of this handle upon releasing the pressure, and after the transverse pin 28 has moved over an inclined face, the upper portion of the cam member 20 has the diametrically opposite slots 30, the walls of which connect into the upper ends of the inclined faces.

To facilitate'the simultaneous and equal movements of the opposite ends of the cooperating roll 6 when moving away from the `power driven roll 5, the lower end of the tensioning rod 19 has the recess 31 to receive the coil spring 32. Vhen the tensioning rod is in either of its innermost positions to tension the resilient bowed member 15, the latter rests against lthe lower end of the tensioning rod; but when the mechanism is tripped, the spring 32 will clamp the resilient bowed member against the base 33 of the U-shaped portion of the clip 21` which base forms an extended bearing for the resilient bowed member and thereby prevents rocking movement of the resilient bowed member relative to the tensioning rod. rIhis resilient bowed member is preferably formed with the lug 34 which is engageable within the lower convolution of the coil spring 32 to longitudinally7 position the resilient bowed member. The bearing blocks 13 also preferably have their sides slightly tapering to avoid too great a vfrictional resistance to their movements.

To limit the upward movement of the cooperating roll 6 when the mechanism is tripped, the complementary sections 2 and 3 of the wringer frame are spaced apart a distance less than the diameter of the cooperating roll and have the transversely extending fianges 35 which are adapted to be engaged by the cooperating roll. To drain any'water which drops ofi` the ends of the rolls inwardly away from the ends of the wringer frame, there are inwardly extending and downwardly inclined ianges 36 beneath the power driven roll.
