Application filed .Tune 11` 1917.

To aZZ whom t may concern:

Be it known that I, GUSTAV B. KEIL, a citizen of the United States` and av resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gearing; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being' had to the acompanying drawings, and to the letters of reference marked thereon, which forni a part of this specication.

This invention relates to improvements in gearing and consists of the matters hereinafter 'described and more particularly pointed out in the appended claims.

The improved gearing is herein illustrated as applied to a washing machine of the cylinder type, the present invention including means for driving and controlling a wringer mounted on the washing machine Vand which may be swung in a horizontal plane into any position, desired by the operator without destroying the driving connection between said wringer and the other parts of the gearing.

The many advantages of my invention will appear as I proceed with my 'specification.

In the drawings:

Figure 1 is a view representing a front end elevation of a washing machine of the cylinder type, 1to which a gearing embodying my invention is applied.

Fig. 2 is a fragmentary view representing a side elevation of the same, with the wringer swung' into a position at a right angle to that shown in Fig. 1.

Fig. 3 is a detail, vertical sectional view through the gearing, the plane of the .section being indicated by the line 3 3 of Fig. Fig. 4 is a detail, horizontal sectional view through the washing machine, the pla-ne of the section being indicated by the line d i of Fig. 2.

Referring now in detail to that embodiment of my invention illustrated in the drawingsz--lO indicates a main support for the gearing which, asillustrated in this particular instance` is the tub of a washing machine of the drinn or cylinder type. The tub is mounted at its corners upon upright legs,

arranged in pairs. only the front pairs o-f legs,

11, 12, being shown herein. The said legs are made of angle bars, so placed that 'their angles deline the corners of the support, all

of the said legs, of course, having casters and V being suitably connected to each other in a manner and for the purpose well known. The front pair of legs 11, 12, are suitably connected together at their top ends by a transversely extending angle bar 13, the horizontal flange of which is spaced below the top ends of said legs, and the lbottoml ends of said legs are connected by a smaller angle bar 14. l

The tub 10 is made of sheet metal and includes an upright front wall 15 which is spaced back of or within the vertical plane ofthe legs 11 and 12. A horizontal plate 16 (see Fig. 3) forms 'a top closure for the space between said front wall 15 and the angle bar 13 at the top of said legs. The plate 16 is bent about the upright flange of the angle bar 13 and terminates in an upright, transversely extending wall 17 arranged in the plane of the front faces of the legs 11 and 12. To the bottom edge of the wall 17 is hinged an apron or door 18 which provides a closure for the space between said legs Il and 12 and the front wall 15 of the tub body 10. The said front wall 15 is extended upwardly and forwardly from the plate 16 into the plane of the top'edge of the angle bar 13 where it is attached to a second horizontal plate 19 which forms in effect a continuation of a lid 2O for the tub body. This lid is of familiar construction and is capable of being` raised into an open position to give access toA the interior of th'e tub body.

25 indicates a bracket plate upon which is mounted and carried the power transmission or gearing mechanism. Said plate is located within and toward the bottom of the space provided vbetween the front end. wall 15 of the tub body and the front legs 11 and 12, and is rigidly iixed to said front legs. It comprises a body of suitable form whichis placed adjacent the upright front wall l'of the tub, and a plurality of laterally extending arms 26, 2T. which are fixed respectively to the said front legs 11 and 12. Between its ends and at its top. the said bracket plate has au overh:inging` forwardly extending 105 shaft Bel of a nmtor suitably mounted on the tub body, behind an upright plate fixed 'body of sa e,

A pulley 32 of quite large diameter is fixed to that end of said shaft 3l. which ,projects beyond the front face of the flange 28, and said pulley is 4driven by a belt 3B from the arnuiture to the angle bei. 14. This plate is bent inwardly at it ip end to meet the frontend Wall l5 of the 'tub oody.

y L a spur pinion 36 which meshes with a epi ll of larger diametenf, rota.- `tively :moan id on a stud 3S fixed in the bracket plate, in a plane to and somewhat beloiv the shaft 3l. A. spur gear 39 of smaller diameter is made intel al with the gear 3T, and said gear 89 nieslies with a larger spur @fear l0 rotativ l, mounted on a stud #lil fixed in the bracket 'plate 25 in a plane to one side of and above the stud 3S and nearer to the leg ll. 'The lai geni.' al() has a crank pin 4t2 Whicluis oi'nnatively connected to a rack bar and said rack bar :is adapted to inipart a rotary, oscillatory movement to a segmental gear l-l loosely mounted in the shaft 29 adjacent the inner face of the depending flange QS. ik roller mounted loosely on 'the shaft ill supports the free end of the rack bar in operative engagement with the segmental gear 411-. A suitable clutch device #lll provided on the shaft Q9 by means of which said shaft may be oper* ali'velv conneitted to and disconnected from the segmental gear l-l. said clutch device being Vcontrolled by a lever 47 outside the tub body near the leg ll.

ends in the body of' the plate Fixed tothe shaft 31 near the body ofA niitted to the shaft 29 and associated operating device 30, through the olutch'device 46 yat the will of the operator.

50 indicates a horizontally disposed, transversely extending shaft, which is located in a plane above and which extends at a right angle. to the shaft 29. This shaft- 50' is jouriiialed at its inner end, in the top end of the depending flange 28, and at its outer end in a suitable bearing sleeve 50 made integl'al with that part of the bracket plate Q5 fixed to the upright leg 11. Loosely mounted on the shaft 50, nearer its outer than its inner end, are oppositely facing bevel gears 51, 52, which are provided on their opposed faces With clutches 51-, 52, respectively. Said bevel gears mesh with a larger bevel gear 53 fixed to and co--axial with a spur gear 54.- mounted in a| suitable ustud (not shown) projecting forwardly from the bracket plate 25. The-spur gear til meshes with and is driven by the spur gear 40 before mentioned. A clutch collar 55 is keyed on the shaft 5() .between ythe gears 51, 52, and is adapted to engage either ofthe clutches 51, 52a, of said gears, so that the shaft 50 may be driven in either direction or remain idle, even when the gear 5l is rotating.'

A bell crank lever 5G mounted on the bracket has a depending arm 5e which engages with said clutch collar, while its laterally extendingarm 59 projects through an opening 60 (see Fig. 2) in 'the side Wall ofthe tub body near the front leg ll. The projecting end of the lateral arm 59 engages in'an opening (ll in an arm of a two-part controlling lever which is pivoted on a lug '63 made integral with a casing (Si fixed to the before mentioned side wall of the tub body-and the leg il, respeclivcly, by means of screws 65. Said controlling lever'co-acts With arcuately spaced notches 66, G7,.and 68 respectively, formed in the top curved Wall 64a of' the casing 64. 1"llfhe said notches correspond With the two engaging and the neutral positions of the clutch collar relative to the gears 5l.,

70 indicates a short upright shaft,v which is journaled in a bearing sleeve 7l forming a part of the bracket 25, and located inthe angle of the leg 1l in a plane above that of the shaft 50. This upright shaft Yhas a bevel gear 72 fixed to its bottoni end which meshes with a similar gear 73 fixed to the shaft 5l) adjacent the bevel gear thereon. To the top end of the shaft 70 which terminales in a plane below the angle bar 13 before mentioned, is a collar 75, said collar and the gear T2-preventing end'vvise movenient of the shaft 70 in its bearing sleeve.

76 indicates a second upright shaft arranged in .ial alinenient with the shaft T just mentnied, and said second upright shaft is join'naled in a bearing block 77 flied v to its bottom end, a collar 7 9 which is coupled to the sleeve 75 ina ina-nner to provide a -fiexible driving connection be- `tween the shafts 70, 76, which will coinpensate for such disalineinent as may occur in assembling of the parts. T he shafts 70, 76, thus forni in effect, a s iiigle, flexible shaft.

The bearing block 77 projects for some ydistance beyond the top of the horizontal plate 19 forming a part of the tub body 10 where it is reduced in diameter to provide a sleeve 7S and upon which is rotatively mounted a bracket 80. Said bracket is adapted to be attached to and support a wringer 8l iii such manner that the wringer may beswung horizontally about the -shaft 76 as an axis, in any desired position, there being means for locking the bracket and ivringer in said desired position. The bracket 80 comprises a tubular sleeve 82 which is adapted to be mounted on the sleeve 7 S before mentioned, and a laterally extending arm 83 which isadapted for attachment to the frame of the ivringer 8l. The top pai. of the sleeve SZ'teiminates in a shell 84, which, together with a removable cap piece 85, forms a gear casing, as will soon be apparent. The laterally extending arm 83 includes a bearing sleeve 86 in #,vi'liich .is journaled the propecting end of lthe lower Wri'nger roll shaft 81', a b'evel gear 87 being fixed yto that endvof said shaft within the gear casing formed by the shell S4: and the cap 85 before mentioned. The gear 87 meshes with a similar gear S8 fixed to the top end of the upright shaft 7 6 before mentioned. A hand Wheel 90 is screwthreaded through vthe sleeve 82 of the' bracket 80 and and by means of] which the said bracket and associated Wringeriare held-in the desired, adjusted'horizontal position.

It is apparent that by means of the tiva part controlling lever 62 before described, the clutch 55 on the shaft 50 may. be brought into operative engagement avith either of the gears 51, 52, so'that said shaft 50 may be rotatively driven in either direction.

This rotation of the shaft 50, through the gears 72 and 73 is imparted to the upright shafts and 76 and consequentl, 'f `ougn the gears 88 and 87 to the Wringer sii-aft Slf. My improved geaiing'possesses manyl ad- 'vantages All of the operating p arts of the. gearing are inclosed, thus insuring safety tothe operator, and a noiseless mechanism. Bv the construction -of and connection ben tween the upright shafts 70 and 7 6y before mentioned, any slight inaccuracies as may may be accommodated for in assemg the parts. By loosening the hand Wheel, e e ivringer may be swung into any desired '7, ,izontal position Without disengagement between the gears S8 and 87 after whichsaid wringer may be locked in the neiv adjusted position. i
