To all whom it may concern."

Be 1t known that I, JAMES Wayne, inthe county of Allen and State of Indiana, have invented certain new anduseful Improvements in Clothes Wringers, of which the following is a specification.

My invention relates in some features more particularly to clothes wringers intended to be power driven, as is the case where they are used in conjunction with power washing machines, and in some particulars it bears more especially on a safety release for permitting Sudden removal of the tension between the rolls, as is sometimes requisite to prevent injury to the hands of the operator ordamage to materials being wrung. M,y invention consists in the features of construction and arrangement hereinafter more fully described and pointed out in the claims. In the drawing wherein I have illustrated anembodiment of my invention Figure 1 is a front elevation, with parts in section, showing the construction of the wringer and its association with the power shaft, 2 is a a detail of a clutch shiftingmember, and Fig. 3 is a detail of a frame member for the power roll.

In the drawings 10 indicates in general the wringer frame, shown as comprising end castings 11 and 12 connected by a bridge or top member 13, such frame supporting the lower and upper rolls 14 and 15 and the.- pivoted drip board 16. The frame as an entircty is secured at its end member 11 to a. rotatable head lif lcarried by a supporting bracket 18, rigidly mounted in any suitable fashion, not shown, with respect to the fixed support such as the washing machine frame. A latch structure 18' associated' with the bracket18 locks the rotatable head 17 in adjusted position onthe bracket, and a shaft 19, driven from a suitable source of power, shown, extends up through the bracket '18 .to connect with reversing gearing 20 within the head 17 to drive the shaft for roll- 14.

- In the specific construction shown the side casting 11 of the wringer frame has a ballbearing 21'for ashai'ft 22 of roll 14, the opposite extremity of the shaft being supported in a similar ballbearing 21 in end casting 12. Each ballbearingpreferably has its cup member forced into the frame part,

whereas the shaft makes a neat but slidable fit with the inner, or grooved member. The shaft has a squared end to detachably engage an element of the spur gear couple 23, that is housed in a chamber 24 of frame member 12 and the cover plate 25 for such chamber screwed to the frame end 12, has an aperture 26 to give access to the polygonal extremity 22 of shaft 22, so adapting the wringer to receive a hand crank. The other member of the gear couple 23 is mounted on the squared end portion of shaft 27 for the upper roll 15,

and this shaft is supported in ballbearings 28 in vertically movable guide members 29, each of which is a casting guided vertically between lugs 29 of the frame ends and the sides of the bridge 13. Each guide has pendant limbs'30 that straddle the shaft 22 between roller 14 and the proximate end and the spring that spans between them. Upon top of the bridge is a boss or dome 35 having a downwardly opening circular recess 36 with which communicates a slot 37, v

the side walls of which are formed to afiord bearing fora pintle 3B for a latch lever 39. Through the top of thedome there is an opening 40 loosely to receive a screw or. threaded spindle 41 hearing a hand wheel 42, this screw preferably extending through a relatively large opening 43 in lever 39, and within the dome engaging a circular nut 44 sh tted as -at-45 along one side and capable of axial movement to the extent of the height of the dome-recess. The downwardly extending head oflever 39 constantly engages in the slot 45 and has a tooth 46 to engage the top ofthe nut when is shaped to work in slot 37 with edge 37 as a back-stop. It

its nose 47 is fully in the slot 45, at which I time the horizontally extending handle por; tion 39' of the lever-is fully raised by the action of coiled spring 48 that seats, in opposedrecesses in the lever and the dome. Accordingly when the parts are in the normal position shown in- Fig, 1 the upward pressure on nut 44 tends to lock the handle 39 raised, and nut 44 is held near the bottom of'the dome-recess against both rotary displacement and axial movement by the head of lever 89. Obviously by turning screw 41 the point of the spindle, bearingon the center of spring 33, may be screwed down to put the spring under desired tension and press the rolls 14 and 15 together. Downward pressure exerted on handle 39 moves the tooth 46 0f latch lever 39 into reglster with slot 45 in the nut so that the latter, re-

lieved ofvertical restraint, will spring up into the top of the dome. Thismotionis enough fully to relieve the pressure between the rolls and prevent'injtiry to the hand of i the operator or to material in passing between the rolls. Of course to restore the lock to normal position the spindle will be screwed back untilnut. 44 can drop1 again under the tooth 46-of the late, which the threaded spindle'is turned toretension the spring 33.

In. the arrangement wringer I prefer that head 17 shall have a tubular'base extension 50 I rovided withseveral vertical slots 51 and into a tubular bearing portion 52 of racket 4 18; On ears 53. of the bracket'I'mount a pivot 53" for the latch 'l's' the nosetof which may enter any one of, the appropriate slots 51 as the latch is-press'ed home by its: sprin 53"; By pressing on the handleof the late the head 17 is freed to' rotatein' its-fposition of ad'ustment with respect to the bracket 18," I and t e head is freed forvdetaeh nent-from the bracket.

Among the advantages ofthe' construction it may be pointed outtbat the removability down after for swinging. the.

extendin down vent rotation. an

of the entire head 18 with thewringer, and shaft stub 19' attached is very desirable, to facilitate packing, making repairs, etc., and the removability of the rolls is especially advantageous. One has but to loosen screw 34 at the rightof Fig. 1 to detach head 12 and with it "remove gears 23 from the squared shaft ends. The rolls on their shafts may then be removed from engagenient with their hearing rings, shaft 22 slipping out of engagement with gear 58. The,

arrangement for enabling the wringer to be hand operated-by attaching a handle to shaft 22' is also very desirable. 1 While I have herein-described insome detail a s ecific embodiment of my invention, it will-lie understood that changes in particular construction may be made without departure from the spirit of my invention within the scope ofmy appended claims. What I clan'n is:
