NEcTIoN `Walter L. Kauffman, II, Erie, Pa., assignor to ’ Lovell’Manufacturin g Company, Erie, Pa., a corporation of Bennsylvania Application December 21, 1933, serial No. 703,354 >6 Claims. (Cl. 68-32) The present invention is designed to improve the connection between a wringer and its support. that the openings I'I and in consequence the Power wringers as ordinarily made are formed as a unit and secured to a wringer support, this 5 support usually providing a means through which to> transmit the power to the Wringer. The wringer in use is subjected to very frequent strains which are carried into, or through the connection and which tend to loosen the connec Yl0 tion between the Wringer and its support. With the present invention a stile of the wringer is provided with projections which extend into sock ets in the support, these projections and the Walls of the socket taking a large part of the strain through the connection. Preferably the secur ing studs extend directly through the projection into the support, the heads of which are prefer ably housed within the projection. Features and details of the invention will appear from the 20 specification and claims. A preferred embodiment of the invention is illustrated in the accompanying drawing as fol lows:- ` Fig. 1 shows a vertical section of an end of a 25 wringer and a part of its support on the line I _I in Fig. 2. Fig. 2 an end view of the wringer removed from its support and partly in section on the line 3-3 in Fig. 1. 30 Fig. 3 a front elevation of the wringer. Fig. 4 a central section of a modiñcation. I marks the base of the wringer frame, 2 the side stiles and 3 the top bar. These are ordi narily constructed of sheet metal, the side stile 35 being usually of box form with slots 4 on their inner faces through which shafts 5 and 6 oi' wringer rolls ‘I and 8 extend. Journal boxes 9 and I 0 are arranged Within the stile, the upper journal box being slidably supported therein and 40 subject to pressure from the usual pressure spring II. The power shaft of the wringer is coupled ordi narily with a shaft I2 extending through a sup port I3. 'I‘he support is provided with sockets I4 45 on the face next the wringer stile and the wringer stile is provided with projections I5 which ex tend into these sockets. These projections are preferably formed by striking them up in the sheet metal yforming the outer side Wall of the 50 box-shaped stile. Studs I6 extend through open ings Iï extending through the walls of the pro jection and these studs extend into screw-thread ed openings I8 in the support I3. Heads I9 of the 'studs are housed within recesses 20 formed 55 at the rear of the projections. It will be noted heads of the studs are directly opposite the slot 4 so that the studs may be readily put in place through this slot and the studs set up by tools extended through the slot. Preferably there is little clearance between the end of the projection and the bottom of the recess and a slight clearance between the face of the support and the wall of the stile and the walls of the projections and recesses are slightly conical l0 so that as the studs are set up there is a pressed engagement between the walls of the stud and the Walls of the recess which forms a very rigid and secure connection between the support and the wringer. The slight resiliency of the metal form- 15 ing the rear stile as it is drawn up tends to main tain the rigidity of the connection in use. With this construction the connecting studs, or bolts, are entirely sealed so that the supporting walls of the wringer support may be entirely 20 free from obstructions thus making it easier to fabricate and to plate, or polish, and also permit ting of a more attractive structure and one more readily kept clean. In Fig. 4 I have shown a modification in which 25 an outer ‘wall 2a of the stile is provided with a slight indentation 2I which has an opening through it. A cup-shaped ñtting 22 is arranged in the opening in the indentation 2| and this is provided with a flange 22a which is arranged in 30 the recess formed by the indentation. The fitting has an opening 23 which is adapted to receive a stud 24 for securing the wringer to a support. The stud head 25 is housed in a recess 26 formed by the fitting. 35 What I claim as new is: 1. A wringer frame comprising a side stile of box form having a shaft receiving slot on its inner side and a projection on the outer wall of the stile opposite the slot, said projection being 40 adapted to engage a recess in a wringer support and having an opening for receiving a securing stud. 2. A wringer frame comprising a side stile of box formation having a wringer shaft slot in its 4,5 inner Wall and a plurality of projections in its outer wall opposite the slot, said projection being adapted to engage sockets in a wringer support and having openings therethrough adapted to receive securing studs. 3. A wringer comprising a side stile of box form having formed on the outer Wall thereof a mem ber of a projection and socket connection for a support, the inner wall of the stile being slotted and the outer wall having a screw-receiving open-- 55 2,107,539 2 ing opposite the slot in close relation to the member. 4. In a wring-er, the combination' of a stile of box form having a projection on the outer wall with a perforation through the projection and a recess within the stile at the rear of the projec-V tion; a wringer support having a recess receiving the projection and a screw-threaded opening in alinement with the ‘opening through the recess,Y the peripheral walls of the projection and recess being included and in direct wedging contact;> and a screw extending throught the opening'in the projection into the screwf'threaded opening` inv the support and having its head housed in the wringer support having between them recess and projection securing members having included pe ripheral walls in direct wedging contact and a screw extending through'the projection and walls 'of the recess and drawing said peripheral walls into engagement, said screw being opposite the » opening in the inner wall of the stile and oper able through said opening. l Y ~ 6. In a wringer, the combination cfa frame, comprising a stile of box form havingan outer 10 Wall formed therein and ‘a’ projection adapted to engage a socket in a wrin'ger'support, said pro . jection having an opening therethrough adapted lto receive asecuring screw,»the rear of the pro~` recess, said screw being operable Ythrough the ` jection being recessed and adapted to house the inner Wall of the stile.
