Original No. 1,453.568. dated May 1, 1923, Serial No. 471,186, filed Kay 20, 1921. Application for reissue filed February 23. 1924. Serial No. 694,780.

To all IF/(H1, it 'Illllf/ concern.

lie it known that I, EDGAR D. MIsNER, a citizen of the United States, resldln at Detroit, in the county of \Vaync and i tatc of Michigan, have invented new and useful e. The invention has for one of its objects the provision of means which, is rotatable in opposite directions to predetermined positions to move one of the rolls of the wringer toward the other and to hold this movable roll under different tension; and also the provision of a cam member having inclined faces terminating in off-set steps for cooperating with the rotatable tensioning member 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 I simultaneous and equal movementsof the opposite ends of the movable roll when moving away from the other roll. Further ob jeets of the invention reside in the novel features .of construction as more fully hereinafter set forth.

In the drawin Fig. 1 is a si e elevation partly broken away and in section, of a wringer embodying my invention.

Fig. 2 is a top plan view thereof; Fig. 3 is a cross section on the line 3-3 of Fig. 1;

Fig. 4 is a bottom plan view of the stepped cam member;

- Fig. 5 is a cross section on the line 5-5 of Fig. 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 hearing blocks 8 at its oppositeends which are positioned between the complementary sections 2 and 3. 9 is a gear secured to one end of the shaft 7 and adapted to mesh with the gear 10 secured to the corresponding end of the shaft 11 of the coo eratin roll, these two gears being inclose 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 abovethe 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 sides of the bearing blocks 13 :md have circular openings 18 near their lower ends for engagement with the shaft 11, these circular apertures being of sufficient 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 tops of the hearing 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 member15 and longitudinally movable in the cam member 20 secured centrally to the top of the frame 1. This tensioning rod is secured at its lower end to 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.

Forthe 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 steps, the particular face and step being dependent 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 bowed member when the transverse pin is in from its engaged step;

en agement with each ofthese steps.

0 release the pressure of the cooperating roll upon the power driven roll it is merely necessary to rotate the tensioning rod 19 to disen age its transverse pin 28 from its engage step, when the pin will ride up over an inclined face. The flat steps 26 and 27 on either side make the releasing movement in either direction similar. The handle 29 is provided at the up er end of the tensioning rod for rotating t e same to move the cooperating roll 6 toward the power driven roll or for disengaging the transverse pin and to prevent r0- tation 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. The handle extending each side of the tensioning rod is conveniently located to permit it to be instantly actuated by the operator in case of accident as for instance the catching of a hand in the rolls and the sli ht circumferential extent of the steps 26 an 27 make a very short turn necessary to affect a release.

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. When the tensioning rod is in either of its innermost positions to tension the resilient bowed member 15, the latter rests against the 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. This resilient bowed member is preferably formed with the lug 34 which is engageable within the lower convolution of the coil spring 32 to longitudinally position the resilient bowed member; The bearing blocks 13 also preferably have their sides slightly tapering to avoid too great a frictional 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 engaged by any water which drops off the ends of the 1 1o ls of the wringer frame are spaced apart a distance less than the diameter of the cooperating roll and have the transversely" extending flanges .35 which an adapted to be the cooperating roll. To drain inwardly away from the ends of the wranger frame, there are inwardly extending and downwardly inclined flanges 36 beneath the power driven roll.
