Referring to the accompanying drawings, I show a wringer I2, having a frame IS, a transmission housing 20, a transmission mechanism 24. a lower wringer r01 and an pending application Serial 23, 1939.

The transmissio g 20 of wringer l2 and has gears 242 and 244 (see Fig. 3) rotata sociated with a in any manner operatively as suitable power device, not shown, desired.

A is .slidably 6, intermed pinion gears 242 and 244. Such 252 has a grooved-ring portion he central portion thereof, and has teeth portions 256 and 258 located on the upper and lower surfaces, respectively, thereof. The teeth portions 256 and 258 of member 252 cooperate with notched portions 260 in the pinion gears 242 and the clutch member 252 is r driven shaft 246 in a man- 254 located in t 244, respectively, as moved along the powe ectional view taken along 4 2 e e ctional view taken along the line ational view of the n mechanism 24 is located the clutch sleeve 214 is mounted within ner to he hereinafter described. A beveled gear 264, which is, in this instance, considered a part of the auxiliary sociated with the pinion gears 242 and 244 and with the wringer roll shaft 186 associated with the lower wringer roll 68, so as to transmit power thereto.

An operating handle 246 rotatably mounted upon the housing 28 operates the reversing clutch member 252 by means of an eccentrically mounted pin 266 rigidly attached thereto in response to rotational movements of the handle, in a well known manner.

The auxiliary gaging mechanism 28, see Figs. 3 to 9, inclusive, comprises the beveled gear 264 which, in this instance, includes an elongated rearwardly extending sleeve portion 210, a lever operating rack 212, a sleeve member 214, a supporting device 216 which is, in this instance, a part of the transmission housing, and a resilient member 218 operatively associated with the sleeve member 214 and the support 216. The beveled gear 264 has, in this instance, the cylindrical sleeve 210 made integral therewith. However, it is to be understood that, if desired the sleeve portion 210 may be removably attached to the beveled gear 264 whatsoever.

The rearwardly extending cylindrical sleeve portion 216 has the outside surface thereof machined to form a bearing surface to cooperate with the inside surface of the sleeve 214. The the supporting structure 216 and the sleeve 216 may be mounted therein. The beveled gear 264 and sleeve portion 216 are thus Journaled within the sleeve 214 and, accordingly, are free torotate within such sleeve 214 asan A circular notched portion. 280 is out about the circumference of the sleeve portion 216 to cooperate with the lever operating rack 212 in a manner and for a purpose as hereinafter described.

The lever operating rack212 comprises two members 3H) and 3l2 which are substantially semi-circular in shape (see Figs. 4 and 6) The members 3 I and 312 are formed from sheet metal with upstanding outer walls 314 and 234, and with substantially semi-circularly shaped upstanding inner walls 316 and 236, respectively. Radlally outward extending ears 311 may be functionally integral with the inner walls 3i6 and 236 to enable the two members 310 and 312 to be joined together. These members are joined together, by means of bolts 238 which extend through the ears 311, so as to form substantially a dish-shaped device having a cylindricallyshaped aperture 356 therethrough.

Handles 318 are'rigidly attached to the upstanding outer walls 314 and 234 or may be formed integrally therewith. The handles 316 extend radially from the outer walls 314 and 234, and are substantially opposite each other. The handles are of such length to extend outside the wringer l2, through suitable vertically extending elongated apertures 3l9 located in the housing 20 (see Figs. 1, 2 and Suitable knobs 304 are positioned at the end of the handles 318 to enable an operator to readily operate the mechanism 28, as hereinafter described.

A hardened steel cam-plate or member 292 is attached to the outer surface of the inner upstanding wall 316 of member 316 in any desirable manner. An irregular V-shaped slot 290 is out within the inner upstanding wall 316 of the opshifting or engaging and disenmechanism 28, is operatively as- V the operating walls 314 and 234 erating rack 212 and within the hardened steel cam member 292 (see Figs. 4 and 9). A set screw 286 is attached to the sleeve 214 and cooperates with the V-shaped slot 298 and with an elongated slot 288 in the support 216 to operate the mechanism 28, as hereinafter described.

The central portion of the outer upstanding of the lever operating rack 212 extend somewhat above the remaining portion of the walls, and have inwardly extending curved flanges 360 located at each end (see Figs. 4, 6, '7 The curved flanges 360 provide a bearing 98, which may rotate rack 212 in either direction to disengage the shifting mechanism simultaneously with the actuation of the safety release mechanism. The cam 98 is attached to and rotates with the pressure shaft H16 which is a part of porting device 21B .member 214 is thus the wringer safety release and pressure mechanism 3i, as is fully described in my copending application, Serial No. 288,311, filed August 4, 1939. The shaft is adapted to rotate in a clockwise direction upon the release of the roll pressure. The cam 98 will thus, through 'its cooperation with the flanges 366, cause the operating rack 212 to be actuated and to disengage the'connection through the mechanism in a manner as hereinafter described and as described and claimed in the above-identified application.

The sleeve member 214 has an outwardly extending flanged portion 262 located at the end thereof and is slidably mounted within the supporting device so that the flange 282 is located farthest from the beveled gear 264 when the sleeveportion thereof is positioned within the sleeve member 214. The resilient member 218 is-located about the. outside of sleeve 214 and within the supporting device 216. A shoulder 284 in the supporting device 216 cooperates with the resilient member and limits its movement within the supporting device The sleeve slidably mounted within the support 216 and is biased away from the reversing mechanism or powersupplying means by the resilient member 218.

The set screw 286 is threadedly engaged with the sleeve 214 within an aperture 285 and extends into the circular notch 280 in the cylindrical sleeve portion 210 of the beveled gear 264 (see Fig. 5). The set screw 286, rigidly attached to the sleeve 214,'in addition to cooperating with beveled gear 264, extends outwardly through the aperture 288 located within the supporting device 216, through the irregularly shaped aperture 290 located within the lever-operating rack 212, and through the hardened steel cam 292 attached to the outside of the lever-operating rack 212. It is, therefore, obvious that the set screw 286 is operatively engaged with the, beveled gear 264, sleeve member 214, support 216 and the operating rack 212, and that such set screw will move wlththe sleeve member 214 and within the slot 288.

When assembling the mechanism 28, the resilient member 218 is positioned over'the sleeve 214 substantially as shown in Figs. 3, 4 and 5. The sleeve 214 with the'resilient member 216 positioned thereon is then mounted within the supin such a manner that the threaded aperture 285 will be in line with the slot 288 in support 216. The resilient member thus engages the flange 282 and shoulder 284 and biases the sleeve member 214 outwardly.

The beveled gear 264 with the operatively associated cylindrical sleeve portion 210 is then slid within the sleeve member 214 and into such a position that the circular notch therein will be located substantially below or in line with the threaded apertures285 in the sleeve member 214 and the slot 288. The set screw 286 may then be inserted within the aperture 288, within the support 216, and tightened down upon the sleeve 214 within threaded aperture 285. The beveled gear 264 and sleeve portion 216 will then be free to rotate within the sleeve member 214, but, due to the cooperative action of the set screw 286, such gear cannot move longitudinally with respect to the sleeve member 214. However, due to the set screw 286 being positioned within the slot 288 in they support 216, the beveled gear 264 and sleeve member 214 can and will move longitudinally together within the confines of the slot 288.

The lever-operating ra k 212 may then be positioned about the outside of the supporting device 216 within the housing 26. The irregular V- shaped slot 296 should be positioned in line with the threaded aperture285 and set screw 286, with such set screw 286 positioned within the engaged longitudinal position offthe gear 264 withrespect to the pinions 242 and 244; it being the transmission housing 26 and into the end of the wringer frame I6. A lock-nut 36I is posi tioned thereon and tightened upon the frame I6 to lock the screw 366 in any desired position.

It is, therefore, obvious that the set-screws 366 may be adjustably moved into' or out of the irregular V-shaped slot 296. The set screw 286 212 and of the hardened steel cam 292 attachedthereto.

It is to be understood that, as the lever operating rack 212 is positioned about and operatively associated with the support 216, the operating handles, functionally integral therewith, will be positioned through the slots 3I9 in the wringer housing 26. The operating knobs 364 will thus be positioned outside the wringer with one on either side thereof.

With the auxiliary mechanism 28 assembled in such a manner, it is apparent that the resilient member 218, operatively associated with the flanged portion 282 of the sleeve member 214 and the shoulder portion 284 of the supporting device 216, will bias the sleeve member 214 longitudinally within the supporting device 216. Since the set screw 286 is rigidly attached to the sleeve member 214, and operatively associated with the cylind ical sleeve portion 216 of the beveled gear 264, it is apparent that the beveled gear 264 will be moved longitudinally simultaneously with the movement of the sleeve member 214. However, the longitudinal movement of the beveledgear 264 and the sleeve member 214 will be limited by the dimensions of the slotted aperture 288 located within the supporting device 216. The aperture 298 will likewise prevent the rotation of the sleeve member 214 within the supporting device 216, since due to its shape it I will permit only the longitudinal motion of the 216 by means of a plurality of ball-headed set screws 366. or the like, operatively associated with the transmission housing 26 and the supporting device 216 through the bosses 362, integral therewith, see Figs. 3 and 4. In addition,

the screws 366 provide means for adjusting the transmission housing 26 so as to provide means for adjusting the running engagement between the pinions 242 and 244 and the gear 264 while such pinion and gearare in an operating or cooperative engagement. This structure then permits the gear to be adjusted after the wringer has been assembled and provides means for eliminating any noise produced by improper alignment therebetween.

The auxiliary mechanism 28 is operatively associated with the lower wringer roll 66 through the cooperation of a universalv coupling I84. The coupling I84 is loosely associated with the mechanism 28 through a cylindrical sleeve bearing 294 and a pin 296. The cylindrical sleeve bearing 294 is located within the free or open end of the cylindrical sleeve 216 operatively associated with the beveled gear 264. The pin 296 may be rigidly attached to the sleeve portion 216 near the open end and along a transverse diameter thereof, and may be inserted through the sleeve bearing 294. may be positioned about the outside of the pin 296, if desired.

The universal coupling I84, which may be a slotted member loosely attached to the roll shaft I86 by means of a pin I85, may then be mounted within the sleeve bearing 294 with the notched portion thereoi cooperating with the pm 296. The rotational energy of the beveled gear 264 will thus be transmitted through the cylindrical sleeve portion 216, the pin 296, the universal coupling I84 and the lower wringer roll shaft I86.

When operating the auxiliary shifting or engaging. and disengagingmechanism 28 embodying my invention, the lever operating rack 212 may be manually rotated about the supporting device 216 by means of the operating knobs 364,

rigidly attached to the said lever operating rack '212, through the handles 3I8. The rack 212 may also be rotated automatically, so as to disengage the clutch, in unison with the safety release mechanism through the cooperative action of pressure shaft I66 and by means of the cam 98 engaging the flanges 366. As the lever operating rack 212 is rotated from an engaged 'position about the supporting device 216 with the beveled gear 264 engaging the pinion gears, the set screw 286, operatively disposed within the aperture 296, will move longitudinally within the aperture 288, due to its cooperative action with the cam 292 and due to the aperture 268 preventing the rotation of the set screw 286.

The aperture 296 is substantially V-shaped (see Fig. 9) and has flattened portions 366 located at each end thereof. Due to the Presence of the flattened portion 366 of the aperture 296,

the set screw 286, when resting therein, with the beveled gear engaging one of the pinion gears, will hold said beveled gear in such en- A tubular bearing 298 cam 292.

4 p gagement against the longitudinal biasing action of the resilient member 218. However, as the lever operating rack 212 is rotated slightly so that the set screw 288 will be just beyond the flattened portion 388, the resilient member 218 will then force the sleeve member 214 and set screw 286 in a longitudinal manner causing the lever operating rack 212 to rotate. The set screw 286 will thus come to rest in the bottom portion of the V-shaped aperture 268 (see Fig. 9).

As the set screw moves from the flattened portion 386 to the V-shaped portion 388, the sleeve 214 will move a longitudinal distance equal to the length of the aperture 288, which is substantially the longitudinal distance between the flattened'portion 386 and the V-shaped portion 388 of the aperture 288. As the set screw and the sleeve member 214 move in such a manner, the beveled gear 264 and the cylindrical sleeve portion 218, due to the cooperating action of the set screw 286 within the circular notched portion 288, will likewise be moved longitudinally within the supporting device 216, a distance equal to the longitudinal movement of the set screw 286.

It is, therefore, obvious that, as the set screw 286, which .was located in the flattened portion 386 of the aperture 288 with the clutch in an engaged position, is moved from such position to the apex of the V-shaped portion 388 of the aperture 288, the beveled gear 264 will be moved longitudinally a distance corresponding to such longitudinal movement of the set screw 286, and the lever operating rack will be rotated a distance corresponding to the rotational movement of the It is further obvious that with the set screw 286 in the apex portion of the V-shaped groove 288 the beveled gear 264 will be moved to the right or will be disengaged from the pinion gears. In other words the mechanism 28 will be disengaged from the power supply delivered to the wringer rolls from either pinion without afiecting the reversing or transmission mechanism setting.

To force the beveled gear 264 back to its original position, it is merely necessary to rotate the lever operating rack in either direction so that the set screw 286 will be forced back to either flattened portion 386. As the lever operating rack 212 is rotated by handle 3i8, the set screw286 will be forced along the aperture 288 by means of cam 282 causing the pin 286, since it is prevented from rotation by aperture 288, to move longitudinally within the aperture 288 until it comes to rest upon a flattened portion of the aperture 288. As the lever operating rack 212 is operated in such a manner, the set screw 286 will be moved from the right-hand position, as shown in Fig. 9 to the left-hand position as shown in Fig. 5, where such set screw will be resting along the flattened surface 386. As the set screw 288 is movedlongitudinally to the left, the beveled gear 264, through the cooperating action of the set screw 286 within the circular notch 288, will likewise be moved to the left, and will be in a position to engage or will engage the pinions.

It is, therefore, obvious that the lever operating rack 212 may move the beveled gear 264 either from left-hand or engaged position to a right-hand or disengaged position by merely rotating the lever-operating rack in one direction or the other. It is further obvious that with the lever located in a neutral position, that is, with the beveled gear 264 in it right-hand or inoperative position, such rack may be moved in either direction to force the beveled gear 264 back into an operative or to its left-hand position.

The resilient member 218, which biases the sleeve 214 and set screw 286 to the right and the well known normal thrust action of gear 264, cause the sleeve 214 and sleeve portion 218 to be suddenly moved longitudinally as the leveroperating rack 212 is rotated in either direction, in such a manner that set screw 288 becomes disengaged from the flat portion 386 of slot 298. In other words, the mechanism will be disengaged automatically by resilient member 218 when the lever-operating rack is rotated far enough so that the set screw 286 will leave the flat portion 386 of slot 298. By having the length of the flat portion 386 small, it is apparent that the amount of rotation required by rack 212 to operate the shifting mechanism will likewise be small. As an operator rotates the rack 212 by means oi. a slight touch on either handle 384,

.rack 212 will permit the set screw 286 to move within the aperture 288 and in turn move the bevel gear 264 longitudinally in the supporting device 216.

It is, therefore, obvious that the mechanism 28 may be operated automatically through the action of the resilient member 218 by means of a light touch of an operator upon handles 284 or by the action of cam 98 on the flanges 368.

Various modifications may be made in the device embodying my invention without departing from the spirit and scope thereof, and I desire, therefore, that only such limitations shall be placed thereon as are imposed by the prior art and the appended claims.
