JOHN F. HEMENWAY, OF NEW YORK, N. Y.

CLOTHES-WBINGER.

Application filed April 1, 1916, Serial No. 88,247. Renewed October 23, 1916.

To all whom it may concern Be it known that I, J OHN F. I-IEMENWAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in 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 clothes wringers, and more particularly to pressure releasing means for instantaneously releasing the pressure on the rolls, the object being to provide a clothes-wringer in which the top bar carrying the pressure screws is normally held in position within the side bars of the wringer frame by a spring which is capable of being shifted by striking the same into such position that the top bar is free to move vertically in order to release the pressure on the rolls.

Another object of my invention is to provide a clothes wringer with the pressure releasing device so constructed that the top bar is limited inv its vertical movement so as to prevent the same from becoming detached from the wringer frame.

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 of a clothes wringer partly in section showing the application of my improved construction of pressure roll releasing device thereto. Fig. 2 is a top plan view, and Fig. 3 is a detail perspective view-of a portion of the wringer frame.

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

In the drawing 1 indicates a wringer frame formed of a pair of side bars 2 and 3 connected together adjacent their lower ends by cross bars 4 and provided with slotted portions in which are mounted bearings 5 and 6 carrying shafts 7 and 8 provided with cooperating pressure rolls 9 and 10 having meshing gears, not shown, in-

closed by casings 11. 6 are provided with spring supports 12 on which are mounted coil pressure springs 13 into the upper end of which extend the depending stud portions 14 of bearing plates 15 carried by a pressure bar 16 slidably mounted in the slotted portions of the side bars 2 and 3.

The construction of wringers thus far described, is substantially the same as wringers now in use, the pressure rolls 9 and 10 being held in contact with one another by the pressure bar and springs.

Slidably mounted within the upper portion of the slotted side bars 2 and 3 is a top bar 17 which is provided with threaded boxes 18 adjacent its ends in which are mounted the threaded lower ends of pressure screws 19, adapted to engage the bearing plates 15 of the pressure bar 16 in order to exert a pressure on the pressure bar and through the medium of the pressure springs, the pressure rolls are held in contact with one another so as to exert the desired pressure on the clothes passing between the same. i

In order to provide means for holding the top bar 17 in its proper position Within the slotted upper ends of the side bars 2 and 3 so as to allow the pressure screws to exert the desired pressure on the pressure bar, I provide side bars 2 and 3 with U-shaped members 20 which are provided with offset upwardly projecting slotted lugs 21 through which the horizontally disposed reduced ends 22 of a bowed spring 23 are adapted to pass, said horizontally disposed portions of the springs 23 normally resting on bearings 24 secured on the ends of the top bar 17 as clearly shown in Figs. 1 and 2. .The bowed spring 23 is provided with slotted portions 25 through which unthreaded portions of the pressure screws 19 pass as clearly shown in Fig. 1, so as to allow the spring free movement in respect to the pressure screws. When the top bar is in position as shown in Fig. 1, it is held by the horizontally disposed portions of the. bowed spring rigidly in posi- The upper bearings tion within the slotted upper ends of the side bars 2 and 3 so that the pressure screws can exert the desired pressure on the pressure bar 16. In case of a foreign object being accidentally drawn between the pres sure rolls, it is only necessary to strike the bowed spring 23 so as to elongate the same which will force the horizontally disposed ends thereof into the slots of the ofiset lugs 21 into such position that the top bar 17 is allowed a limited upward movement which instantaneously releases the pressure on the pressure'rolls. It will be seen that the bowed spring is so shaped adjacent the horizontally disposed portions that when the ends of the spring are forced outwardly by exerting a downward pressure on the bowed spring, the spring is forced into such position that the top bar can move upwardly within the bowed portion thereof, but is limited in its movement so as to prevent the top from becoming detached from the wringer frame, the bearings 24E allowing the ends of the spring to move freely when the same is struck a blow.

From the foregoing description it will be seen that I have provided a clothes wringer with a movable mounted top bar held in position by a bowed spring so as to allow the top bar to move vertically when the horizontally disposed portions, of the, bowed spring are forced off of the ends of the top bar whereby the pressure on the pressure rolls can be instantaneously released in case of an operators. hand being drawn between the pressure rolls, and while Ihave shown my pressure releasing device attached to a hand operated wringer, it is, of course, understood that the same, can be used with good advantages in connection with power operated wringers, and I do not wish to limit myself to the use of the pressure roll release in connection with any particular construction of wringer as the main object to be accomplished is to provide a wringer with a movable mounted top bar normally held in position by the. ends of a bowed spring which when elongated are moved out of the path of travel of the top bar, so as to allow the same, to. move vertically.

I claim:

1. A clothes wringer comprising a frame having pressure rolls and pressure means mounted therein, a movably mounted top bar mounted within the frame of said wringer, members secured to the side bars of said frame having upwardly extending slotted portions, and a bowed spring having horizontally disposed portions at its ends extending through the slots of said extension for preventing upward movement of sa d op bar.

2; A clothes wringer comprising a frame having pressure-rolls and pressure means posed portion arranged in the slots of said offset lugs for preventing upward movemerit-of said top bar, said horizontally disposed ends being capable of being forced through said slot out of the path of travel of-said top bar allowing said top bar to move vertically within said frame.

3. A clothes wringer comprising a frame having pressure rolls and pressure means mounted therein, U-shaped members secured to the upper ends of the side bars of said frame having offset upwardly projecting slotted lugs extending therefrom, 'a top bar mounted in the side bars of said frame having bearing plates at its ends, pressure screws carried by said top bar for adjusting the pres sure means, a bowed spring having slotted portions to receive said pressure screws and provided with horizontally disposed ends mounted within the slotted lugs of said U- shaped member for preventing upward movement of said top bar, said spring being capable of being elongated to throw the horizontally disposed ends through the slots of the lugs to allow said top bar to move vertically within said frame to release the pressure on said pressure rolls.
