Application filed September 20, 1920 Serial No. 411,548.

T aZZ whom it may concern) Be it known that l, BnUNeoN S. h ioCn'rorr- EN, a citizen of the United States of America residing at Plainfield, in the county of Union and State of New Jersey, have inventen certain new and useful Improvements in TV ringers, of which the following is a specification.

This invention relates to clothes wringers and consists in certain improvements in the construction thereof to be hereinafter fully described and particularly pointed out in the claims.

The invention has for its object to provide means for instantiy releasing the pressure on the rolls, when the operator get her hand caught by the rolls or for the purpose of releasing abnormally large or bunched articles which may be drawn between the rolls.

Other and further objects will be part apparent and in part described as the specification is proceeded with.

In the accompanying drawings:

Figure 1 is a plan view or my invention;

Figure 2 is a vertical longitudinal sectional view of the same;

Figure 3 is a horizontal sectional view of the bushing;

Figure 4 is a side elevation of same;

Figure 5 is a plan view of sleeve showing a portion of the angle plate;

Figure 6 is a vertical sectional view at the same; and

Figure 7 is a diagrammatic view of s eeve and bushing showing manner in which they cooperate.

Referring more particularly to the drawings in which like reference numerals refer to corresponding parts throughout the several views 5 denotes a wringer frame comprising end bars or uprigl'its 6 and side bars 7. Pressure rolls 8 only the upper one of: which is shown in the drawing, are suitably mounted in the end bars 6 and are maintained under suitable compression by means of spiral compression springs 10 seated at their lower ends against the bearing blocks 11 of the roll 8, it being understood that these bearing blocks are slidably mounted in the end bar 6. Seated in the tops of the compression springs 10 are a pair of cup shaped members 9 in turn engaged by compression screws 12 the mounting and operation of which will be presently de scribed.

Bolted to and extending over the tops of the end bars 6 of the wringer frame are a pair 01' angle plates 13 having upstancing sleeves 1 iormed integral therewith. The interior of the sleeves 1d are provided with vertical ribs r projections 15 having inclined faces 16 adapted to engage or mesh with the inclined faces 17 of vertical ribs or projections 18 formed on bushings 19 turn rotatably mounted in the sleeves 1%. These ribs 15 and 18 in effect form spiral threads. The bores 20 of the bushings 19 are threaded or the reception of the compression screws 2. Consequently when the screws 12 are crowed down by means of the crank handles 21] rined thereon, the movable upper com- 1 .-sion roll may be placed under any desired in; ession, through the action of the com- .5 ion springs 10.

Owing to the fact that the normal upward thrust of the compression roll 8 tends to rotate the bushings 19 in the sleeves 14: in an anticlockwise direction thus ausing the bushings and with them the compression screws to move upwardly thereby reducing the compression or the rolls, some means must be provided for locking the bushings against such rotation until manually released. This is accomplished by means of a rod or the like 22 adapted to exteno diagonally across the top of the wringer with its ends seated in diagonally disposed pockets :23 formed in the angle plates 13. The ends of this rod when so seated lie directly in the path of rotation of the arms formed on the bushings and of course serve to hold the bushings stationary.

ln the event of the operator having her hand drawn between the rolls, all that is necessary for her to do to relieve the compression between and permit separation of the rolls is to strike or bear against the rod 22 causing the latter to be pushed out of the open ends 25 of the pockets 23, thus freeing the rod from engagement with the arms 24:. The rod can be readily pushed out of the pockets from either side of the wringer frame and the release oi one end of the rod automatically results in the release of the 1 the ribs 15.

sleeves when the ribs 18 are aligned with the spaces between the ribs 15. 7

Any suitable means such as chains 27 may be employed to prevent the rod 22 from fall ing off or down into the interior of the frame.

Having thus described my invention, what I claim is:

l. A clothes wringer comprising a frame,

rolls and compression means therefor mounted in said frame, angle plates secured to said frame at each end thereof, said plates being formed with sleeves having interior ribsthereon, bushings rotatablv and slidably mounted. in said sleeves and having exterior ribs, the ribs on said sleeves and said bushings having engaging oppositely inclined portions, compression screws mounted in said bushings engaging said compression means whereby the upward thrust of said rolls causes said bushings to rotate upwardly in said sleeves, and means for normally pre venting such upward movement of said bushing. 2. A clothes wringer comprising a frame, rolls and compression means therefor mounted in said frame, a bushing rotatably and slidably mounted in said frame,a compression screw carried by said bushing engaging said compression means permitting the raising of saidbushing when rotated but pre venting such raising except when rotated, said bushing adapted to be raised in said frame by the upward thrust of the compression means to relieve said compression, and readily releasable means for preventing such rotation of the bushing.

3. A clothes wringer comprising a frame, rolls and compression means therefor mounted in said frame, sleeves mounted on each end of the frame, bushings :in said sleeves having arms thereon, said bushings and sleeves having ribs with inclined engaging portions, and compression screws carried by said bushings and engaging said compression means whereby said bushings are adapted to be rotatably raised in said sleeves by the upward thrust of said compression means to relieve the compression between the rolls, and quick releasable means'extending between the arms on said bushings for normally preventing such rotation of said bushings. i

i. A clothes wringer comprising a frame, rolls and compression means therefor mounted in said frame, sleeves mounted on opposite ends of the frame, bushings rotatably mounted in said sleeves, said sleeves and bushings having longitudinal spaced intermeshing ribs "formed with engaging inclined faces, compression screws carried by said bushings engaging said compression means, whereby the upward thrust of said compression. means causes the bushings to rotate and. the ribs of said bushings to ride upwardly between the ribs of said sleeves to relieve the compression between said rolls, means on the ribs of said bushings adapted to limit said upward movement and means for normally preventing the rotation of said bushings.

5. A clothes wringer comprising a frame, rolls and compression means therefor mounted in said frame, sleeves mounted on opposite ends of the frame, bushings rotatably mounted in said sleeves, said sleeves and bushings having spaced intermeshing ribs formed with inclined engaging faces, compression. screws carried by said bushings engaging said compression means, whereby the upward thrust of said compression means causes the bushings to rotate and the ribs of said bushings to ride upwardly between the ribs of said sleeves, and quick releasable means for lockingsaid bushings against rotation.

In testimony whereof I affix my signature.
