I. "WEIGHT, 015 WASHINGTON, DISTRICT OF COLUMBIA.

, CLOTHES WBINGER.

Application filed March 28, 1918.

To all whom it may concern:

Be it known that I. REA P. WRIGHT. a citizen of the United States, residing in the city of Washington, District of Columbia, have invented certain new and useful Improvements in Clothes lVringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in clothes wringers. the object being to provide a reversing mechanism for reversing the pressure rolls on the abnormal separation thereof. said mechanism being so constructed that the mechanism will be returned to normal position when the rolls return to normal position, where l by the pressure rolls will be reversed when a thick bunch of clothes or the operators wringer so as to force the clothes out from between the rolls, and as soon as the rolls are released by the clothes they will be rotated in the ordinary manner so that the clothes can be fed between the same.

Another object of my invention is to provide a reversing mechanism which is exceedingly simple and cheap in construction and one which can be readily attached to any wringer now in use.

Another and further object of the invention is to provide novel means for adjusting the reversing mechanism in order to enable the same to be set in operation when the rolls are separated a predetermined distance.

Other and further objects and advantages of the invention will be herein after set forth and the novel features thereof defined by the appended claims. 4

In the drawings Figure 1 is a side elevation of a clothes wringer of the ordinary construction showing the application of my improved construction of reversin rmechanism thereto.

Figure 2 is an enlarged vertical section through a portion of a wringer-and the reversing mechanism; and c Figure 3 is a. similar view showing the gears in reversedposition.

Like numerals of reference refer to like parts in the several figures of the drawin In the drawing 1 indicates a wringer frame which is provided with

superimposed pressure rolls

2 and 3 over which is arranged pressure means 4 the tension of which is adiustedby pressure screws 5, in ordinary manner. The presses roll's2fiand 3 are Serial No. 225,245. l

carried by shafts 6 and 7 having meshing gears 8 and. 9 so as to cause the rolls to be rotated in unison. said gears being preferably enclosed by gear casings 10.

Secured to one of the side bars of the wringer frame is a. bracket 11 which is provided with a bearing 12 for the lower shaft 6. said bracket having an arm 13 provided with a bearing 14. in which is slidably mounted a clutch shifting member 15 pro vided with a slot 16 through which the shaft 7 is adapted to extend. Themember 15 carries an adjusting screw 17 preferably provided with a ballsh aped head 18 so that the same can be readily rotated or grasped. by the operator for the purpose which. will be hereinafter fully described.

The bracket is provided with a bearing 19 in which revolubly mounted the sleeve portion 20 of a beveled gear 21 arranged around the shaft 6. said sleeve portion being formed integral with a pulley 22 over which is adapted to pass a drive belt. The pulley is pro-vided with a collar 23 to which is adapted to be secured a crank 24L so as to allow the beveled gear 21 to be rotated either by hand or power. and while I have shown a pulley formed integral with the beveled gear 21, it is of course understood that a gear could be substituted therefor. so as to engage a driving gear without departing from the spirit of my invention.

A beveled. gear 24; is revolubly mounted on a vertical hearing 25 of the bracket 11 and is adapted to engage the beveled gear 21 and a beveled gear 26 loosely mounted on the shaft 6 as clearly shown.

The

beveled gears

21 and 26 are provided 7 with female clutch faces 27 and 28 which are adapted to be engaged by the clutch faces 29 and 30 of a double male clutch which is keyed on the shaft 6 to slide thereon. thebore of the male clutch being preferably provided with a slot to receive the key fixed in the shaft. it is of course understood that this double male clutch can be slidably mounted on the shaft 6 of the. pressure roll 2 in various ways without departing from the spirit of my invention.

The clutch shifting member is provided with a slotted lower portion which is arranged within, a central groove 31 formed in the double clutch member, said clutch shifting inember having:

cam faces

32 and ,33, so COllStIl'l'C td that when the clutch shifting member 1.5 is in the posi the clutch tion shown in Fig. 2 the clutch face thereof is 'inengagement with the clutch face of the beveled gear 21 so as to lock said beveled gear to the shaft 6 whereby the

pressure rolls

2 and 3 will be rotated in the direction to draw the clothes between the pressure rolls. As the upper roll 8 rises by the passage of an obstruction such as a thick bunch of clothes or the operators hand the clutch member 15 is raised vertically within the bearing 1 L so as to bring the cam face 32 into engagement with the wall of the groove 31 which moves the clutch member longitudinally on the shaft .so as to throw the clutch face thereof into engagementwith the clutch face 28 of the beveled gear 26 which locks said beveled gear 26 to the shaft 6 and as the beveled gear 21 is being driven the beveled gear 26 through the intermediate gear 24 will be rotated in a reversed direction so as to reverse the travel of the

pressure rolls

2 and 3 which will force the obstruction drawn between the rolls backwardly so as ;to allow the upper roll to return to its normal position, and. by such movement the double clutch will be returned to its normal position so as to lock the beveled gear 21 to the shaft 6 which will cause the pressure rolls to be: rotated in the ordinary manner. I v

The. adjusting screw 17 can be adjusted up and down in the member 15 so that the wringer can be set in order to enable the release to be actuated on the separation of the rolls at predetermined distances and as the shaft works in a slot formed in the member 15, theemember 15 is free to move upwardly independent of the movement of the shaft whereby the gears can be shifted manually by grasping the knob of the screw and lifting the member 15 vertically.

In the operation of a wringer provided with, a reversing mechanism, as herein shown and describeol ,I have provided means for reversing. the rotation of the pressure r0115 automatically by the abnormal separation of the pressure rolls, but by the con struction herein shown and described, the operator can reverse the rolls by simply grasping the head 18 of the screw 17 and raising-upwardly thereon so as to operate shifting member and it will be seen from this construction that mutual .means ar provided as well as automatic 7 means. for reversing the rotation of the rolls.

wi e w t a this particular construction of shifting mechanism for the double clutch the same canbe adJusted so as to cause the mechanism to be set into operation on the passage of ifierent fliic me es of e mater a cla m;
