or DAYTON,

porting post 22, and 'an inverted U-shaped wringer frame 23 which is fdetachably secured to bracket 20 by studs 24 engaging tapped holes 24a in frame 23, and by screws 24b passing through holes 24 in frame 23 and threaded into bracket 2 0.

The bracket 2O includes a portion 'which is integral with the hub 21 and whichvincludes two flange members 2()a joined by a web: 20". The edges of the flanges 20a provide surfaces which are parallel to the axis of the hub 21 and provide mounting surfaces against 'which the wringer frame 23 -is secured. The web 20b 4provides a mounting surface for receiving the power head to be described.

The wringer bracket-hubi21 is provided with notches, one shown at 118 in Fig. 1,

which are adapted to receive a. lug 119 carried by post 22 for holding the wringer in a desired operating position. To change the position of the wringer the operator swings the unit causing one notch 118 to move away from lu@r 119 and another notch to bey received iy lug 119 to yieldingly maintain the wringer unit in a new position.

Po/wefq head.

' The power head 25 of the wringer unit will now be described. This power head includes an electric motor 25El provided with a brush lifting reversing switch operated by a lever 120. The switch .is disclosed in the copendl ingapplication. of Ralph L. Lee, Serial No. 629,201, nfiled March 31, v1923. `For the understanding of the present invention'it is suiicient to state that the lever 120 is movable to cause the motor to turnin either direction or to stop the motor. f v

The casing of the' motor includes a part which is integral witha gear housing 27 which is attached toI the web 20" of the. bracket 20v byl screws 36. The armature shaft of the' motor is provided with a worm 26 which isl adapted to extend into the gear housing 27 and drive a-worm gear 28 located therein. Gear housing 27 is open at ,one side and this opening is provided with a cover 29 held in place by screws 30. lAn oil filler opening 31 is provided and 'is closed lll by filler plug 32. Gear housingv 27 is provided with bearing 33 which is adapted to v receive operating shaft 34 to which the gear 28 is keyed. 'llhe bearing 33 provides a relatively long bearing surface for the shaft 34.

'lhe shaft 34 extends through the gear housing 27 and a wall of the web 201 of the I bracket 20. Illhe opening in the bracket l through which the shaft 34 extends is cylindrical and somewhat larger than the shaft and is adapted to receive a cup washer 37 which with the wall of housing 27 provides a lubricant receiving chamber 33.'

During the `operation of the motor some of the oil splashed within the gear housing 27 will enter the passage 39 and flow to the chamber 38 to lubricate ,the shaft 34; rlhe excess lubricant Hows through. the passage 40 back into the gear housing; andsince the lubricant-level in housing 2 is below the f shaft 34, little if any lubricant in said chamber 38 will tend to llowf out around the shaft 34.

lt will be noted that the web 2Ob and the flange member20'f1 are offset in vertical plane from thel airis of hub 21. The purpose of this is to extend the wringer frame 23 a vsubstantial* distance from the supporting post 22 so that the post. is not in the way of the operator; also, by thus oifsetting, 'the` motor 'can be mounted substantially above said post. lin this manner a compact unitary structure is provided in which the controller lever 120 for the motor is readily Iaccessible tofthe operator whether the operthe other of the f ator isone-one side or wringer. Y p

l lwringing apparatus. The 4wringer frame 23 includes inverted U-shaped side frames and`51 held together by bolts 52. Frames 50and 51 may be considered half shell portions', and each are provided Awith downwardly'1- extending side walls 53 which form with the tops of Frames strip member 57 is secured to each lower y.bearing and is adapted to bear against thelfra- mes 50 and 51 to maintain'said bearings 55 in correct position (see Fig. 3), and

to prevent accidental-dislocation of the bear' ings- 55, such as might occur when the wringer unit is shipped with roller pressure released, orwhen the pressure is suddenly released by means of a quick release device to be described. v lPressure or wringerrolls 68 and 69 are carried by shafts 70 'and 7l, respectively.

' .Shaft 70 bears downwardly'upon the lower bearing 55 while the upper bearing 56 bears ydownwardly upon the shaft 71. Pressure between the rolls is suppliedby a pressure incense s ring 72 located within the `channel53ahaft 70.01. the lower "roll is ccnnected with the operating shaft 34 of the power head by means of a universal coupling including sleeve 75 provided with notches 76.

Shafts 34 and 70 each carry pins 77 which slide within the notches 76 and wire 78 is wrapped around `the sleeve 75 so as to prevent the pin 77 from moving. endwisc. Shafts and 71 are connected by gears 79 and 80 which are enclosed by the bracket 20.

The side walls 53 of the wringer lframe members 50 and-51 extend-'downwardly to enclose the bearings 55 and 56 and the ends of the rolls and to provide an opening for` the introduction of clothes. By enclosing the gearing, universal coupling, andi roll ends, danger to the operator and to the clothes is substantially reduced. Y llt is a'paprent from the foregoing that th power head device and wringing device are removably mounted on opposite sides of the bracket'20; that the wringing device can be removed while still assembled without disturbing the power head device and that the disconnection of the wringing device auto-` matically interrupts the power transmitting connection from the power head device to the wringing device. After the wringer is -removed, the power head can be removed 'as a unit by removing bolts 36.

Means areprovided in the wringing device for permitting endwise removal of rollers, shafts, bearings, and the springs, the wringing device bein detached vfrom bracket 20 by the removal o the nuts from studs 24 and by the removal of screws 241.'Referring more in particular t0 Fig. 5, the inwardly extending ribs 54 which function as guide' members for the bearings 55 an 56 are'notched to provide enlarged openings 121 and 1,22

throughone end of the wringer frame. The opening 121 is large enough that the spring 72' may befremoved therethrough endwise. A lower opening 122 is largeenugh to 'permit the rolle- rs 69 and 70 and bearings 55 and 56 to be removed endwisethrough it.

vAfter tension of spring 72 has been released," the spring 72 can be withdrawn through the opening 121. The upper wringer roll 69 and one bearing 56 are then pushed into the upper part ofthe wringer frame and in so doing the lower roller 70 ca-n be raised highenough so that it can be removed through theopening 122. One lower bearing 55 can' then be removed.v AThe upper 'roller 69 -isf' then lowered to adjacent the opening 122 and then removed, and a bearing 56 is removed.

The right hand end or branch ofthewl'illge'. frame 23 is closed by the end-walls of the. frames 50 and 5'1 (see Fig. 6'), and the ribs 54 adjacent this end are notched so that he other bearings 55 and -56 in 'this branch f' the frame cany be reinved from' the inside `of the Wringer frame. The bracket 20 PrO- tension spring 7 2.

" portion 86 in engagement with the inclined portion 85 of the plate82. When the lever vides a closure for the openings in the left end oi' branch of the wringer frame 23- so that both ends of the frame are enclosed in the unitary structure. The web 2()a provided in bracket 20l prevents the spring 7 2 moving endwise to the left as viewed in Fig. 1..

Wringer release.y

'.lhe center of the top. of the frame 50 and :31is provided with an opening having a hinged cover or latch plate 82pivoted at 83 and carries an adjusting screwv8et for the 'lhe free end of the plate S2 is provided with a slightlyupwardly inelined portion 85 which cooperates with the hook portion 86 of a latch lever 87. Latch lever 87 is pivoted upon frame28 by pin 88, located substantially directly below the free end of the plate 82. ln thisl manner upward tension of the spring 72 on. the adjusting sci-ew 841-. and cover 82 tends to hold a hook .8T is pushed downwardly it will cause the lioolc 86 to move awayfrom the inclined surface 85 so as to clear member 85 whereby plate 82 will swingabout itsI vpivot 83 to release the pressure on the spring 72. A spring 90 is coiled about pin 91 carried by latch lever 86 and engages the runder side 9 2 thereof and .the top of frame 23. Spring 90 tends to return lever 87 to latching position. lTo 'return the cover plate 82 to the position shown in Fig. 1 after the quick release device has been operated, the adjusting screw 84 -is partly unscrewed and the cover 82 is swung to opera-ting position. rlhe plate 82 will engage the surface 93 of lever 86 therebyv forcing it to snap into operating position shown in Fig. 1.

Means are provided for preventingcertain l movable wringer parts from striking the fraine when the quick release device has been operated. rl`his -nieans includes a 'bale 123 connected with cover plate 82 and passing :under .spring 7 2. l/Vhenplate 82 is released,

thebale 126 limits its movement so that the head of screw 84 cannot strike the frame and thus damage or mar the'frame.

Drain board.

.Each rail carries a. trunnion 4screw 61 rotatably and loosely jonrnaled in larger holes 61a provided in the branch portions of thev wringei' traine.v Both trunnion screws 61 are removable endwise through the ends of the frame. To remove the drain board, the

. righthand screw 61 (Fig. .1) is not placed f in positionuntil the drainboard is removed,

then the board can be tilted with respect to theleft hand hole 61a because of the loose- "'ness of fit between the screw 61 and hole 61a,

and then the board can be removed by 'sidewise movement withoiitdisass'enibling the device for maintaining the board in either of'its operating positions. This locking device comprises a sliding pin 68 carried by the :traine 50 (see Fig. 6). Pin 63 has a notch 64 formed by flattening olf a side of pin 63. A pin inserted from the side of the frame 50 is received by the notch 64 and is adapted to cooperate with the ends of the notch to prevent the locking pin 63 frornbeing pulled entirely out of the frame 23. Pin 63 cooperates with holes 66and 67 in the side-rail 60l vthe ends ofthe lower roll 68 and over tthe drainboard' rails 59 and 60. Each ledge is provided with a drip flange 114 located abbve 'the drain board 58, the drain'board58 being cut away slightly as at 116 to provide clearance for said flange 11d. Water tending to f'follow the shafts 70 and 71 drips off onto the ledges 1.18 and is-directed by flanges 114 toward the ldrain board 58. The flanges 114 tend to divert water issuing endwise from the rolls toward the drain board'. The drain board 58 is provided with dripstrips v58a 'tending to prevent water running back under the drain board toward the wringer frame and dripping upon the door.

u Umweg/01'.

The' drain board 58 provides a movable support for the movable wringer conveyor now to=be described. At opposite end edges ofthe board 58 rails `59 and 60 carry rollers 95 `and 96 located parallel to the pressure rolls 68 and'69, and adapted to support. a conveyor belt 97 interposed between the wringer rolls 68 and 69 and therefore ro.l

tated by the movement of these rolls. Rollers and 96 are tapered so as to be larger in diameter at the center than at the end in orderthat, during the movement of the belt,

the belt 'will remain in alignment' with the" Iwringer rolls.

While the forni of mechanism herein.

shown and described constitutes a preferred embodiment of one form of the invention,

it is to be understood that other forms might be adopted and various changes 'and alterations made inthe shape, size, and proportion of the elements therein without departing. from the spirit and scope of invention. f
