CLOTHES-WRINGER.

Application filed December 14, 1916.

' To all whom it may concern:

Be it known that I, EDGAR B. STOCKING, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Clothes-Wringers, of which the following isa specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in automatic pressure releasing means for rotating pressing members such as clothes wringers, mangles, and the like, the object being to provide means for automatically and positively separating the rolls in case of over feeding of material, injury to the hands of the operator, or the entrance of a foreign object between the same.

Another object of my invention is to provide an automatic releasing means in which a mechanism is provided for instantaneously and positively shutting off the power simultaneously with the operation of the releasing means, whereby the rolls are instantaneously separated and the rotation thereof stopped so as to prevent the foreign object, or other cause actuating the release,

7 from being further drawn between the rolls.

Another and further object of the invention is to provide an automatic pressure releasing device in which the meshing gears of the rotating pressure rolls are thrown out of mesh simultaneously with throwing off the power and thereleasing of the pressure in order to allow the clothes wound upon either roll to be unwound therefrom by simply pulling on the clothes thereby overcoming the difliculties now existing in machines of this character in having to reverse the movement of the rolls to remove the clothes therefrom.

Another and further object of the invention is to provide a pressure .roll release which is provided with means for manually releasing the pressure whereby the operator can at any time desired instantaneously release the pressure and shut off the power.

Another and further object of the invention is toprovide a machine which is so constructed that the same can be operated as an ordinary machine of this character by pro viding means for locking the elements involved in such positions that the automatic Specification of Letters Patent.

object from being drawn further between the same.

Another object of the invention is to provide an automatic pressure releasing device in which the rolls can be held in separated position and the pressure adjusted to enable the machine to wring blankets and other thick goods, the upper roll when the parts are in this position being driven by 'ti' n of the goods passing between the rolls.

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

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawings I have shown my improved construction of automatic pressure release applied to an ordinary wringer comprising a frame 1 having slotted side bars 2 provided with bearings 3 in which is mounted the shaft 1 of the lower pressure roll 5 which is extended as shown at 5' and is adapted to be driven by any suitable means as will be hereinafter fully described. Mounted in the frame above the lower pressure roll 5 is an upper pressure roll 6 provided with a shaft 7 carrying bearings 8 on which are mounted coil pressure springs 9 engaged by hearing plates 10 carried by a pressure bar 11, said bearings and pressure springs working in grooves formed in the opposing faces of the slotted side bars in order to guide and hold the bearing and pressure springs in position within the slotted side bars in their vertical movement therein. The upper ends of the slotted side bars are cut away to form shoulders to provide a seat for a movably mounted top bar 12 which is provided with the usual threaded boxes 13 carrying pressure screws 14 engaging the bearing plates 10 carried by the pressure bar 11 so as to adjust the pressure on the upper pressure roll.

The pressure roll carrying shafts 4 and 7 are provided with the usual meshing gears 6 at each end of the rolls 5 and 6 inclosed by gear casings 6 which are connected to the pressure springs by arms 6 in the usual manner.

The walls of the grooves formed in the opposing faces of the slotted side bars are slotted as shown at 15 which slots communicate with vertical bores 16 formed in the side bars at each side of the slot as clearly shown in Figs. 3 and 4. The bearings 8 are provided with depending lug portions embracing the upper pressure roll shaft 7 having openings formed therein through which is adapted to be forced a pin 17 which is provided with a cut-out portion 18 forming shoulders for preventing the longitudinal movement of the pin after the same has been inserted, the upper edge of the pin being provided with a semi-circular recess 19 to receive the shaft 7 so as to securely lock the depending legs of the bearing in position on the shaft.

In order to provide positive means for raising the upper pressure roll so as to separate the rolls when the pressure is released as will be hereinafter fully described, I arrange within the upper portions of the bores 16 contraction springs 20, the lower ends of which embrace the outwardly projecting end portions of the pin 17 and are seated in notches formed therein and the upper ends carry stirrups 21 through which extend adjusting screws 22 carried by plates 23 mounted on the top of the side bars 2. Arranged within the stirrups on the adjusting screws 22 are nuts 24, the corners of which are embedded within the walls of the bores 16 so as to prevent the nuts from turning when the screws are adjusted, and it will be seen that by this construction the tension of the springs can be adjusted. In order to aid the lifting springs 20 in raising the parts of the wringer arranged above the upper pressure roll, I arrange in the lower portions of the bores 16 expansion springs 25 which are pro-- vided with bearing plugs 26 at the upper ends engaging the ends of the pin 17, the lower ends of the expansion springs 25 being mounted on adjusting screws 27 as clearly shown in Fig. 3 in order to adjust the tension of the springs.

It will be seen by this construction that I have provided each of the side bars of the wringer frame with expansion and contraction springs arranged to lift the upper pressure roll and the movable parts above the same when the pressure is released so as to positively separate the rolls. In applying the construction to some forms of wringers, I have found that it is only necessary to employ one pair of springs for raising the upper pressure roll and the movable parts, and I do not wish to limit myself to the use of two sets of springs for accomplishing this result as either set can be eliminated and the same result obtained, the two sets of springs being only used when my improved construction of pressure release is applied to avheavy wringer in which the weight of the movable members above the upper pressure roll is such that it is necessary to provide additional means in connection with one set of springs to raise the movable parts.

Secured to the ends of the top bar 12 are spring catches 28 carrying beveled face catch lugs 29 adapted to engage keeper pins 30 extending across the slots of the side bars so as to hold the top bar in predetermined position on the frame in'order to allow the pressure screws to be adjusted in the ordinary manner for adjusting the pressure on the pressure rolls. Arranged above the keeper pins 30 are stop pins 31 adapted to be engaged by the catch lugs 29 in their upward movement when they have been thrown otf of the keeper pins 30 so as to limit the upward movement of the top bar and hold the same rigidly within the wringer frame to allow the pressure screws to be adjusted when the rolls are separated so that blankets or heavy clothes can be operated upon as shown in Fig. 7.

Mounted on the outer ends of the shaft 7 of the upper pressure roll 6 are operating members 32 and 33 provided with serrated portions 34 engaged by the serrated portions 35 of trip members 36 and locked in their adjusted position by bolts 37, said trip members having inclined faces 38 adapted to engage the outwardly projecting curved lower ends 39 of the spring catches 28 so as to move said spring catches outwardlywhen brought into engagement therewith in order to move the catch lugs out from under the keeper pins 30 to release the top bar when the pressure rolls are separated beyond the distance of ordinary movement in the passage of a proper thickness of clothes therethrough. As the upper rolls 6 are separated by a foreign object or by an overthick feeding of clothes being drawn between the pressure rolls the trip members release the spring catches which instantaneously releases the pressure means and the separating springs lift the upper roll into such position that the foreign object, overfed clothes or hand of the operator are prevented from being drawn'farther between the rolls.

From the construction so far described it will be seen that I have provided means for automatically releasing the pressure on the pressure rolls and for instantaneously positively separating the rolls.

Mounted on the extended portion 5' of the lower pressure roll shaft 4 is a driving member 40 herein shown in the form of a pulley 40 having a hub portion 41 provided with an annular groove at its inner end as shown at 43, the end wall of the groove being provided with a recess 44 adapted to receive a pin 45 secured in the shaft 4 for locking the driving member to the shaft so that the shaft can be rotated through the medium of the driving member, and I preferably instead of a pulley 40, provide the driving member with a detachable crank as shown in dotted lines at 46 in order to allow the machine to be operated manually. The opposite end of the hub 41 of the driving member 40 is annularly recessed as shown at 47 forming a seat for a coil spring 47' which surrounds the outer portion of the extension 5 of the shaft 4 and is inclosed by a cap nut 48 working on the extreme threaded end of the shaft, said cap nut extending over the hub portion in such a manner that the driving member is free to move longitudinally outwardly. on the extension 5 of the shaft for the purpose hereinafter fully described. The inner end of the hub which is provided with a groove is rounded or bev eled as shown at 42 for the purpose hereinafter fully described.

The releasing member 33 is provided with depending legs having enlarged portions 49 provided with inclined faces 50 and fiat faces 51 which are adapted to cooperate with the rolls and at the same time the rolls are free to rotate independent of the driving member so as to allow clothes which may be wound upon either pressure roll to be unwound by simply pulling on the clothes.

As the releasing member 33 is carried upward by the raising of the upper pressure roll the trip member, releasing the spring catches, the inclined face 50 engages the rounded end of the driving member and forces the same outwardly and on the continuous upward movement of the releasing member 33 the flat faces 51 are brought into longitudinal alinement with the inner end of the hub of the driving member in order to form a thrust bearing as the driving member continues to rotate though disengaged from the shaft 5.

In the operation of the wringer as herein shown and described by adjusting thetrip members 36 on the operating members 32 and 33 the device can be set so that the trlp members will engage the spring catches and release the pressure before the power is disconnected or they can be adjusted so that the operating members will be moved vertically a sufiicient distance so as to allow the power to be disconnected before the pressure is released and I have found in practice that the best results can be obtained by adjusting the trip members on the operating members into such position that in the vertical movement of the operating members pressure is released, but in either case the operation of the pressure release and power control is so close together that they are practically simultaneous.

The hub 41 is provided with a threaded bore 52 carrying a set screw 53 which can be forced into engagement with the shaft of the lower pressure roll when the clutch pin 43 is out of the seat 44 of the driving member so as to lock the driving member to the lower shaft in order to enable the shaft to be rotated when the rolls are in separated position which allows the wringer to be used for wringing blankets Or other thick goods.

In connection with the automatlc means for releasing the pressure, separating the rolls and the cutting-off of the power, I provide manually operated means for releasthe power will be disconnected before the ing the spring catches which when operated throws the various parts of the machine into the same position in which they are thrown by the automatic releasing means. The manually operating means consists of a pair of pivoted levers 54 and 55 mounted on the side bars 2 of the wringer frame adjacent their upper ends carrying cross bars 56 and 57 arranged under the free ends of the spring catches 28 in such a manner that when the levers 54, and 55 are oscillated upon their pivots the spring catches will be engaged by the cross bars 56 and 57 so as to throw the stop lugs out of engagement with the keeper pins 30 which instantaneously releases the top bar and allows the lifting springs to separate the rolls and in the separation of the rolls the releasing member 33 is carried upwardly by the upper pressure roll shaft 7 so as to bring the inclined faces thereof into engagement with the hub of the driving member so as to cut off the power. The upper ends of the levers 54: are connected together by a chain 58 arranged in a convenient position to be actuated by the operator of the machine, thus providing protection from injury as hereinbefore described.

From the foregoing description it will be seen that I have provided an automatic pressure release and power cut-off which will operate automatically or can be operated manually, and in connection with a machine constructed as shown and described, I provide means for locking the various parts in such position that the wringer can be used. as an ordinary wringer so that the manual and automatic means are prevented from being operated, and to accomplish this I pivotally mount on the upper end of each of the side bars 2 of the wringer frame a bail 59 which is adapted to embrace the ends of the top bar so as to rigidly secure the top bar in position within the frame in such a manner that it cannot move vertically therein to release the pressure whereby the parts are allowed a slightly free movement with out releasing the pressure or the cut-off of the power.

In the modification shown in Fig. 8 I show the application of my improved construction of releasing member for cutting off the power to a wringer having outside gears lnclosed in a casing in which 60 indicates a frame, 61 and 62 the pressure rolls. and 63 the gear casing inclosing the mesh mg gears not shown. The releasing member 54 carrying the usual trip member 65 which is provided at its lower end with a returnedbend portion 66 having inclined faces 67 adapted to engage the rounded inner end of the hub portion of a driving member 68 so as to move the driving member longitudinally on the shaft in order to throw the clutch pin out of the seat so as to allow the driving member to rotate freely on the shaft.

In the modification shown in Fig. 9, I provide a bearing 70 formed of a casting having integral studs 71 adapted to cotiperate with the springs for raising the upper pressure roll which construction eliminates the use of a pin which can be readily placed over the shaft of the upper pressure roll and slid into position within the side bars of the frame.

In the modification shown in Fig. 10, 72 indicates a side bar of the wringer frame having a vertical bore to receive a contraction spring 73which is provided at its upper end with an internally threaded sleeve 74 held within the convolutions of the spring by friction. Mounted on the top of the side bar 72 over the bore is a washer 75 through which extends an adjusting screw 76 working in the internally threaded sleeve 7 4: to enable the tension of the spring to be adj utsed.
