PRESSURE-ROLL RELEASE FOR CLOTHES-WRINGERS.
Patented Mar. 20, 1917;
Application filed July 26, 1916. Serial No. 111,406.
To all whom it may concern:
Be it known that I, REA P. WRIGHT, a citizen of the United States, residing at Washington, in the District of Columbia, have-invented certain new and useful Improvements in Pressure-Roll Releases for Clothes-Wringers, 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 releases for clothes wringers, the object being to provide a releasingdevice for the pressure rolls of the wringer in the form of a resilient member having its ends interlocked in keepers. carried by the side bar of the wringer in such a manner that the same can be instantaneously released in order to allow the pressure rolls to move vertically.
Another object of my invention is to provide a pressure release which is exceedingly simple and cheap in construction and one which can be readily installed on the ordinary form of clothes wringer now in use.
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 accompanying drawings,
Figure 1 is a front view of a clothes wringer partly in section showing the application of my improved construction of pressure roll release thereto;
Fig. 2 is a section taken on the line 22 of Fig. 1;
Fig. 3 is a detail perspective view of a keeper secured to the inner face of the side bars and a portion of the resilient member;
Fig. 4 is a detail section partly in elevation showing another form of keeper and resilient member, and
Fig. 5 is a perspective view of the keeper and a portion of the resilient member as shown in Fig. 4.
Like numerals of reference refer to like parts in the several figures of the drawing.
In the drawing 1 indicates a wringer frame which is composed of the usual slotted side bars connected together adjacent their lower ends by connecting members; and 2 and 3 the pressure rolls which are carried by shafts arranged in suitable bearings slidably mounted in the slotted side bars of the wringer frame. The upper bearings are preferably provided with spring supports 4 carrying pressure sprlngs 5 on which is mounted a pressure bar 6, the above description being given so that the operation of' tions of the slotted side bars of the wringer.
frame, is a top bar 7 having pressure screws 8 mounted in suitable threaded boxes carried thereby, said pressure screws cooperating with the pressure bars 6 so as to adjust the pressure on the pressure rolls through the medium of the springs.
In constructing my improved release for wringers, I employ a resilient member 9 preferably formed of spring wire having a central bowed portion 10 and horizontally disposed ends 11 which are reduced as shown at 12. In applying the resilient releasing member to a clothes wringer, I provide the top bar 7 with a vertically disposed slot 13 in which the bowed portion 10.0f the resilient member is freely mounted; the horizontally disposed end port-ions 11 being mounted in screw eyes 14 secured to the lower face of the -bar as clearly shown in Fig. 1, forming guides for the end portions of the resilient member in order to allow the resilient member to expand and contract as pressure is placed upon the same and released therefrom, for the purpose hereinafter fully described.
Secured to the inner faces of the side bars of the wringer frame are keepers 15 which are in the form of plates having substantially key-hole shaped slots, the enlarged portionsthereof forming sockets for the eX- treme end portions of the resilient member9 so as to hold the top bar in a predetermined position within the wringer frame to enable the pressure screws 8 to be adjusted to regulate the pressure on the pressure rolls.
When the pressure releasing device .is in the position as shown in Fig. 1, the bowed portion 10 of the resilient member is in a plane above the top bar in such a position that the same can be readily struck by the operator of the wringer when it is desired to release the pressure on the pressure rolls in case of an accident. As the resilient member 9 is removed downwardly by the impact of the blow from the operator of the machine, the ends thereof are moved outwardly by the elongation of the spring, the horizontally disposed portions sliding in the screw eyes 14 until the reduced portions 12 are in alinement with the reduced portions of the key-hole shaped slots in the keepers 15 which allows the top bar to move upwardly.
In the form shown in Figs. 4 and 5, I provide keepers 16 which are secured on the outer faces of the side bars of the wringer frame and are provided with keyhole openings to allow the resilient mem brought into alinement with the reduced portions of the key-hole shaped slots of the keepers allow the top'bar to move vertically within the wringer frame to release the pressure on the pressure rolls. In this form the operation of the resilient member is identical with the operation of the preferred form shown, as when the resilient member is struck a blow, the ends thereof are forced outwardly so as to bring the reduced portions into such position within the keepers that the top bar is' released.
By constructing the resilient member with an offset portion at each .end extending around the pressure screws, I am' able to place the keepers on the outer faces of the side bars, as in some constructions of clothes wringers this might be used with advantage over the keepers arranged on the inner face of the side bars of the wringer frame.
From the foregoing description it will be seen that I have provided a pressure release for clothes wringers which is composed of a resilient member formed of a single piece of wire mounted ina pair of screw eyes and cooperating with a pair of keepers in such a manner that the top bar of the wringer frame is held in position within the wringer frame so that the same can be instantaneously released, as by forming the resilient member of the central bowed portion extendin through the top bar above the upper sur ace thereon, I eliminate operating members of any kind, and I am able torelease the pressure on the rolls quickly.
