JOHN F. I-IEMENWAY, OF NEW YORK, N. Y.
To all whom it may concern:
Be it known that 1, JOHN F. HEMENVAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented cer tain new and useful Improvements in Pressure-Roll Releases for Clothes-\Vringers, 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 pressure roll release for clothes wringers, and is an improvement upon my pressure release as covered in an application executed by me on the 30th day of June, 1916', the object being to provide positive means for operating the releasing spring so as to overcome any danger of the releasing spring snapping back into place after the same has been operated.
Another object of my invention is to provide a releasing device in which the operating member is in the form of 'a screw having such a pitch that by the rotation of said screw one revolution the spring will be moved into such a position that the pressure on the rolls will be released, said spring being held in adjusted position by said thumb screw so as to prevent the device from accidentally becoming set after being released.
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 drawing,
Figure 1 is a front elevation partly in v section of a clothes wringer showing the application of my 1mproved construction of pressure release thereto.
Fig. 2 is a section taken on the line 2-2 of Fig. 1, and
Fig. 3 is a detail perspective view of the releasing spring keeper and operating member.
Like numerals of reference refer to like parts in the several figures of the drawing.
In carrying out my invention I employ a wringer frame 1 composed of slotted side bars 2 connected together at their lower ends by a rod 3, and connecting members 4, and at their upper ends by a movably mounted top bar 5 which is slidably mounted within the upper portions of the slotted side bars 2'.
Slidably mounted in the slotted side bars 2 of the wringer frame are bearings 6 and 7 Specification of Letters Patent.
Patented Mar. 21), 1917..
Application filed July 26, 1916. Serial No. 111,404.
in which the shafts 8 and 9 of the pressure rolls 10 and 11 are mounted, the shafts 8 being extended to provide means for attaching a crank or pulley for operating the same.
' The shafts 8 and 9 are preferably provided with meshing gears, not shown, at each end of the pressure rolls which are inclosed by gear casings 11. The upper shaft bearings 7 are provided with spring supports 8 carrying coil springs 12 upon which are mounted plates 13 carried by a pressure bar 1 1, said plates being provided with depending studs fitting within the top of the springs, as clearly shown in order to hold the pressure bar and springs in their proper positions within the wringer frame. plates 13 form bearings for the lower ends of the pressure screws 15 which are mounted in threaded boxes 15 seated in the ends of the top bar 5 so as to exert the proper pressure on the pressure springs so as to hold the The pressure rolls under the proper tension when.
. tically disposed slot 18 forminga, substantially inverted T-shaped opening in the member, the slots 17 being of a greater width than the slots 18 for the purpose hereinafter fully described. 7 v
Slidably mounted on the under side of the top bar 5 is a spring 19 provided with slots 19 through which screws 21 pass for holding the same in position on the under. face of the top bar in such a manner that the spring 19 is free to slide thereon, and while I have shown screws employed, for slidably mounting the spring on the under face of the side bar, I do not wish to limit myself to this particular construction of connecting the rolls in this class of wringers, the slots allowing the spring to expand and contract for the purpose hereinafter fully described.
The ends of the spring 19 are provided with substantially T-shaped heads 20 formed by providing the spring with oppositely disposed notches to provide reduced portions 21.which are of a width substantially the same or slightly less inwidth than the slots 18 in order to allow the top bar to move vertically when the reduced portions of the springs are drawn into alinement with the slots 18 of the members 16.
The spring 19 is provided with a centrally disposed bowed portion 19 which is adapted to be engaged by the lower end of a thumb screw 22 mounted in a threaded box 23 secured centrallyin the under face of the top bar 5 in order to provide means for depressing the central portion of the spring inorder to draw the reduced portionsof the ends of the spring into alinement with the slots 18, the pitch of the threads being such that by giving the thumb screw a complete turn, the spring will be contracted to such an extent that the reduced portionsjwill be drawn into vertical alinement with the vertical slots 18 so as to allow the top bar to move vertically within the wringer frame. The head 20 of the spring limits the upward movement of the top bar within the wringer frame and prevents the same from becoming accidentally detached therefrom, and itv will be seen that when the thumb screw is revolved positive means is provided for contracting the spring so as to release the pressure on the pressure rollswithout any danger of the pressure release resetting itself.
While I have shown a thumb screw constructed to operate the resilient releasing member, I do not wish to limit myself to any particular construction of revoluble member for th1s purpose as various forms of revoluble members provided with cams could be employed so as to depress the spring centrally in order to contract the same so as to bring the reduced portions into alinement with the slots to release the pres sure means without departing from the spirit of my invention. The operation of the pressure release as herein shown and described is as follows:
Assuming that the top bar of the, pressure means is in the position shown in Fig. 1 when it is desired to instantaneously release the pressure means, it is only necessary to rotate the operating member which is herein shown in the form of a screw which will force the resilient member downwardly so as to draw the ends inwardly in order to bring the reduced portions into alinement with the vertically disposed slots of the members carried by the bars of the wringer frame, which will instantaneously release the pressure by allowing the top bar to more vertically within the frame.
