Patented Mar. 20, ion.
Application filed October 26, 1918. Serial No. 127,900.
have invented certain new and useful Improvements in Automatic Pressure-Rolllieleasing Devices for Clothes-Wrmgers, of which the following is aspecification, reference being had therein to the accompanying drawing.
This invention relates to certain new and useful improvements in automatic pressure roll releasing devices for clothes wringers, and the object of the invention is to simplify the construction of the release by providing the top bar of the wringer frame with slidably mounted internally threaded boxes for the pressure screws in connection with means for holding said boxes in predetermined position within the top bar in such a manner that the boxes will be instantaneously released on the separation of the pressure rolls.
Another object of the invention is to provide a construction of release which can be readily applied to an ordinary oonstruction of wringer, the parts of the release being mounted on the frame of the wringer in such. a manner that it can be readily applied.
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.
In the drawings,
Figure 1 is a side elevation partly in section of a clothes wringer showing the application of my improved construction of pressure release thereto;
Fig. 2 is a detail perspective view of a slidably mounted internally threaded box and a bearing sleeve thereto;
Fig. 3 is a detail vertical section through a slightly modified form; and- Fig. 4 is a detail View of a slightly modified form of'bearing having an extension provided with a bevel the pivoted latch.
Like numerals of reference refer to like parts in the several figures of the drawing.
In the drawing, 1 indicates a wringer frame having slotted side bars 2 in which are mounted superposed pressure rolls 3 and 1 carried by shafts 5 and 6 which are mounted in bearings arranged w1th1n the portion for operating slotted side bars 2, the upper bearings being provided with spring supports 7 carrying pressure springs 8 engaged by hearing plates '9 carried by a pressure bar 10.
Secured within the slotted side bars 2 at their upper ends is a top bar 11 which is provided with a vertical bore adjacent each end in which a tapering bearing sleeve 12 is adapted to be driven from the under side,"said bearing sleeve having oppositely disposed grooves 13 adapted to receive the oppositely disposed ribs 14 of an internally threaded box 15 in order to allow the box to slide within the bearing without rotating therein, said box having a lateral projecting lug 16 at its lower end working in a slot 17 formed in the bearing sleeve 12 for limiting the upward movement of the internally threaded box for the purpose hereinafter described. Mounted within the threaded boxes 15 are pressure screws 18 adapted to engage the bearing plates 9 for adjusting the pressure on the pressure rolls.
Pivotally mounted on the side bars 2 of the wringer frame are latches 19 having 'hook portions 20 at their upper ends exsaid tail portions 21 carrying adjustable trip members 23 arranged above conical members 24 carried by the ends of the shaft 6 of the upper pressure roll 4 so that when the upper pressure roll 4 ismoved away from the lower pressure roll'3, by a foreign object passing between the rolls, the conical members will engage the adjustable trip members 23 and rock the latches 19 on their pivots in order to move the hook portions from off of the boxes 15 which allows the boxes to move vertically within the top bar so that the pressure screws will be moved away from the bearing 9 so as to release the pressure on the pressure rolls.
In the modification shown in Fig. 3, the top bar,25 is provided with a vertical bore in which is slidably mounted an internally threaded box 26 having-2E groove 27 into is adjusted. The end of the top bar is provided with a horizontally disposed opening communicating with the vertical bore of the top bar and through which extends the hook portion 29, of a pivoted latch 30, carried'by the side bar of the wringer frame, said hook portion being adapted to extend into a notch 31 formed in the outer wall of the box' 26, so as to hold said box in predetermined position within the wringer frame in order to enable the pressure screws to be adjusted in the ordinary manner.
By this construction I provide the top bar with a vertical bore in which the threaded box is slidably mounted with a horizontally disposed opening communicating with said bore through which the hook of the pivoted latch extends and is seated in a notch in the box so as to hold the box in such a manner that when the latch is' moved by the separation of the pressure rolls, the box will be released so as to release the pressure means. I In Fig. 4 I have shown an upper bearing 32 of the pressure roll shaft aving an extension provided with a beveled face 23 which is adapted to cotiperate with the trip member of the latch so as to rock the latch on its pivot in order to release the pressure screw carrying boxes.
From the foregoing ,description it will be seen that I have provided a clothes wringer' with slidably mounted pressure screw carrying boxes which are released by the separation of the pressure rolls.
