To all whom t may concern.'

Be it known that I, GUs'rAv B. Kani, a,

ence beingliad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

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

The improved gearing is of especial advantagefor use with a Washing machine of the Cylinder or drum type and is shown herein as applied to such a machine. It is'also adapted for driving a Wringer mounted on said Washing machine.

The many advantages of my invention 1vill appear as l proceed With my specification.

Referring now in detail to that embodiment of my invention as illustrated in the drawings, 10 indicates a main support for the gearing which, as illustrated in this particular instance, is the tub of a washing machine of the drum or cylinder type. The tub is mounted at its corners upon upright front and rear pairs of legs ll, l1a and 12, 12a respectively. Said legs are preferably made of angle bars, placed so that the angles of the 'bars define the corners of the support. The front pair of legs l1, 11a are braced or connected at their top ends by a transversely extending angle iron 13 (see Fig. 2) the horizontal iange of which is spaced from the top ends ofsaid legs, While its vertical flange is arranged in the plane of the front faces of the saidlegs. The legs of each front and rear pair are connected together near their bottom ends by transversely extending brace bars 1% 1ta respectively and each leg of the front pair of legs is connected to the like leg of the rear pair of legs by means of longitudinally extending bars 15, l5, all of which act to connect the legs securely together. Casters are preferably attached to the legs so thatithe support may be easily moved. Y

The tub 10 is made of sheet metal and comprises a transversely rounded bottom Wall 10a, which terminates in upright side Walls 10b, 10b, and upright front and rear end Walls 10c, 10d respectively. A cover or lid l0e is hinged to the top edge of the upright rear Wall 10d.

The front 'wa-1110c of the tub is spaced back of the vertical plane of the front legs 11, l1, A horizontal plate 10t forms a fixed l in closed position. f

i8, i8 indicate longitudinally extending shields or bracing Walls arranged adjacent the upright side Walls 10b ot the tulo and xed attheir ends to the iront and rearA legs respectively. Said shields not only actto strengthen the part of the tulo with which they engage hut have otheriunctions which ywill appear as proceed with any specication. l

lil/yithin the tui) l() is mounted a cylinder or drinn 2O which is adapted :tor an oscillatory or rocking movement in the tnh in a arnil iar manner. Said cylinder/'is oil the usual structure `for Washing machines of this type and comprises upright iront and rear end Walls 2l pertorated transversely round-v ed bottom and side walls 24 and a horizontal top Wall 25. ln said top Wall is provided the usual opening through which the cloth'- ing is introduced or reinoyed troruthe oylin der, said opening heing normally closed hy av removably attached slatted door 26.

Fixed to the rear end wall 22 of the clothes cylinder, in va plane ahov'e its center orp gravity, is a trunnion 2l'. This trunnion is normally journaled in a hearing yoke 28 xed tothe end Wall 'lOl ofthe tulo. l'Said yoke has an upwardly opening hearing slot or groove through which thetrunnion is introduced to its associated hearing surface therein. A v

The -lfront end Wall 2l ofthe cylinder 20 has xedto it a hei-wing plate which is capable oi detachable operative engagement n 'ith a horizontal, power-driven, rotary oscillating stud or shalt 3l, which projects through "the iront Wall l0 oi the tub, l0

in axialralinernent with the trunnion 27.

lt is apparent from the foregoing description that when the sha-itt 3l is at rest, the cylinder Q0 may he removed troni the tub by simply lifting it from its hearing upon the shaft 3l and the hearing' yoke 28, the cover l0@ of the receptacle l0, of course, heing rst opened to permit such removal.

The tub l0 is provided on 'its rounded bottoni Wall l0@ adjacent the rear end Wall 10d With a drain coclr 32 and a sight glass 33 through which the operatorvniay see the level or' the Water in the-tub. (See Figs. 2-3). The upright iront Wall ltlc and horizontal extension Wall lfl ofthe tuloa to# gethcr with the shield'walls ldZ-l and apron l? constitute a gear casing or co npartnient 3l (see Fig. 2) Within the plane ot the front legs ll, il?. ,ln sain casing is located the power driren gearing which irnparts the required oscillatory increment te the cylinder 2G andrvhich also operates a second niechandsin, in this case a tyringer.

indicates a hraclret plate {see upon, which is mounted and carried the Said gearing or potrertranmitting mechanism.

Said lplate is located Within and toward the Y bottoni of the compartment or gear casing 3l and is rigidlyued tol theront legs ll, lia. ltcoraprises a cody 3o which is placed adjacent to the upright iront Wall lOC of the triband a plurality of horizontal, vertically spaced arins 3'?, 38 and 39, 4:0. rlhe arms '373 38g at the right hand end ot the-hodyfterr' rainate in forwardly extending oars 37a, 3,83, whichl are attached to the upright iront leg lla. The arms 39;. l0, at the lett hand end of the hody project forwardly and are attached to the other iront leg il. -Intermediate its ends at its top, the said bracket plate has an oyerhanging, forwardly extending arm lll, which terminates in a depending Harige L22 so `arrar'iged as to provide hearing for the outer end oi the driving stud or shaft 3l he' iiore mentioned. y yilhe inner end of said shaft has hearing an apertured boss formed on the body 36 of said bracket plate.

i3 indicates ahorizontally disposed shaft which is the power shatto the `operating gearing. Said shaft is adapted for continuons rotary motion in one direction and is journaled at its innerend in the loody 36 of the hraolret 35 and Vat its outer end in a suit able argerture formed in the bottom end of the depending flange i2 of the arm al. A, drift-en pulley el oit quite large diameter is' Xed to ,that endl of said shaft which projects beyond the iront face ofthe tlange Fixed to the inner end oit the shaft d3 ad-l jacent to the body BS of said bracket 35 is a` spur pinion' which meshes with a spur gear lo orn larger diameter, rotatively mounted on a stub shaft 47 xed in said oraclret in a plane to one side of (to the left) and below the shaft d3. Madeintegral with Said gear i6 and projecting forwardly therefrom is a spur gear 48 of smaller diameter which meshes with a larger spur gear i9 loosely mounted on a stub shaft 50 xed to the bracket 35 in a plane to one side of (the lett) and abete the shaft a7. This large,Y

gear 49 has a crank. pin 51 towhich is operatively connected a rack har indicated as a Whole hy the reference numeral 52:

The rack har 52 is adapted to impart a rotary oscillating movement to a segmental gear 55 loosely mounted on the 3l in a plane adjacent to the depending @ange d2. A roller 53 rloosely mounted ou the shaft i3 su norts the tree end oi said raclr har in such position that it will always he in operatiye engagement with the segmental gear. The inner or rear jlace of the hub of said segmental gear has clutch teeth 55a which are adapted to he engaged ley like teeth iorrned los on a'clntch collar't'pt (see Fig. 2) ieathered v to the shaft 3i., so as to he mora-ble endwise thereon.

Le clutch collar 55 may he shifted ou the shaft 3l into and out of engagement with the clutch teeth 55a formed on the hub of the segmental ge'ar 55, by means of an arm 60 fixed to the inner end of a transversely extending rock shaft 61; said shaft has bearing at one end in a lug 61a on the bracket body 36 and atI its other end in the arm 39 of said bracket. The arm 60 has a lug at its bottom end which engages within the groove of said clutch collarand at its top, said arm is connected to a spring 62 which is fixed to a horizontal rib at the top edge of said bracket 35. The spring 62 holds the arm 60 at either limits of its movement, that is t0 say, when the clutch collar is either operatively engaged with or disengaged from the vassociated clutch teeth on the hub ofthe segmental gear 55. The outer end of said rock shaft 61 projects through a suitable aperture in the shield wall 18 adjacent the upright leg 11 and is provided without said wall with an operating lever 63.

Itis apparent from the foregoing description that the continuous rotary movement of the shaft 43 is imparted to the gear 49 at a slower speed by means of the intermediate speed reducing gears 45-46-48 before mentioned, and that the rotary motio-n of said gear 49 is transposed into a r0- tary, oscillatory movement of thesegmental gear 55, which movement is transmitted to the cylinder 20 when the controlling lever 63 is in the required position.

To reduce the shock and wear between the segmental gear 55 and the rack bar 52 at the4 ends of the stroke, the rack bar is (see Fig. 5) provided with a longitudinal upwardlyy opening groove 522L in which is located a second bar 52b provided with the rack teeth. The second bar is somewhat shorter than the groove 52:l and springs 52c are placed at its ends to absorb and reduce the shock or Jar when the movement of the rack bar asa whole is reversed.

The pulley 44 on the shaft 43 is vconnected by a belt 57 to a smaller pulley 58 on the shaft of a motor 59, which is carried by the bracket 35 as follows :--64, 65, indicate` larms fixed to the bracket 35 and depending below the rounded bottom wall 10El of the tub 10, where they are'provided with horizontal extensions 64a, 65a. The extension 65a is attached to the front leg 111?.I Parallel, horizontal rods 66, 66 connect the arms 64a, 65a (see Fig. 9) and angle bars 67, 67, slidably mounted upon said rods provide a carria e from which depends the motori-.59. A thum screw y68 carriedbyfthearm65a and threaded through the adjacent angle bar 67 provides means for adjusting vthe position of the motor-'carriage in either direction to secure the proper tension of the driving belt 57. v

The motor is thus located in a plane below the tub and within the tub legs, Where it is out of the way and protected from the Water that may be splashed from -the tub. In addition the motor is insulated from the support and so placed, it balances the weight of the driving gearing on the bracket 35.

To further protect the motor, I provide a plate 69, which has an upright, rear flange 69a fixed to the hanger arm 64 of the bracket plate 35 and a depending front flange 69b attached at its bottom to the transverse brace 14 that connects the front tub legs 11-11a. Said front flange is spaced back of the front plane of the legs 11, 11a to leave space for the belt and pulleys 57, 58, and 44.

The connection between the gearing and the wringer is as follows 70 indicates the wringer which is placed at the front of thc tub with its upright frame members 71-71 attached to'the angle iron 13, that connects the top ends of the front legs 11, 11a. 72, 73 indicate the upper and lower rolls of the wringer. The lower wringer roll 73 has its shaft 74 extended beyond the wringer frame (to the left as viewed in Fig. 1) where it has bearing in an upright standard 75 liXed to the top end of the front leg 11. Secured to the end of said shaft is a sprocket wheel 76 (see Fig. 4) which is operatively'driven by means of a sprocket chain 77 from a smaller sprocket wheel 78 Xed Vto the end of a shaft 79, which has bearing in the arms 39-41 of the bracket 35.

Loosely mounted on the shaft 79 are oppositely facing bevel gears 80, 81, which are provided on their opposed faces with clutches 80a, 81a. Said gears mesh with a larger bevel gear 82 fixed to and co-aXial witha spur gear 83 mounted upon a stud 84 (see Fig. 6) which projects forwardly from the bracket 35. The spur gear 83 is driven by the gear 49. A clutch collar`86 is keyed to the shaft 79 intermediate the gears 8081 and` is adapted to engage either of the clutches 80a, 81aL of the gears 80, 81, so that the shaft 79 may be driven in either direction or the lsaid clutch collar may be held in an intermediate or neutral position so that, even though the bevel gear 82 be rotating, the shaft 79 will remain inoperative. A bell crank lever 87 mounted on a stud 88 on the bracket 35 vertically above the stud 84 has'its depending arm 89'operatively engaging the clutch 86. A laterally extending arm 90 of said bell crank lever proJects through an aperture 91 in theshield wall 18 in a. 4position above the sprocketv 78. A link '92 connects'the arm v90 with an arm 93 of a lever9`4 mounted on a lug 95 made integral with the standard 7 5. :The top. end of said.A

lever 94 is provided with a handle 96 having a detent which coactsv in a familiar way with notches 97, 98, 9 9 see Fig. 4 formed ina flange at the top of the standard 5. The

said notches correspond with the two-engagtingand vthe neutralpositionsuof the' clutch Aas collar. 82 relative to the gears 23d-8l. .el cover plate 100 fixed to the standard *Z5 and adjacent front leg ll, incloses the sprocket Wheels 76, 7S, the associated chainV il?, the

vniajor portion or the lever 9a and the linlr 92. lt is apparent from the foregoing description that the lever 9d rnay be shifted into and locked in position so that the shaft 7d of the Wringer may be driven in either direction from the gear 82, or said lever may be locked in the intermediate position when the shaft Z4 will remain idle though the gear 82 be rotating. Y.

The .operation of a TWashing niachine einloodying my invention is as follows:

The clutch 56 controlling the operation of the cylinder 20 is normally disengaged Jfrom the segmental gear 55 and the said cylinder is at rest. Likewise the clutch S6 is in a neutral or intermediate position, so that-the Wringer rolls are idle. 'lhe shalt 43, how.- ever, after the motor 59 is started, is driven continuously in one direction hy said niotor, as before described. 'lo start the Washing machine., the operator grasps the lever 63 and moves the saine to bring the clutch G into engagement with the segmental gear 55, whereupon an oscillating movement is iniparted to the cylinder 20. lWhen the washing operation has been continued as long as desired, the lever 63 is again operated to remove the clutch 56 from its engagement With the segmental gear 55. Upon such disengagement the opposite face ot the clutch 56 thereof Will engage against the ad- `iacent face oie the hoss providing bearing for the inner end of the shaft 3l, and act as a bra-ke to slow down and {ina-ily stop the oscillation of the cylinder 20. @n account of the relative axial location of the shaft 3l and of 'the trunnion 27, which as before described are located above the center of the gravity ot said cylinder, said cylinder will corne to a position of rest With its top Wall 25 in a horizontal position.

The controlling lever 94 may novv he disengaged from its neutral locked position and be Vmoved forwardly until the detent handle 96 engages Within the notch 98 and a continuous rotary movement will then be imparted to the Wringer rolls in: a ,forward direction. Y f i 'lhe clothing is now removed from .the cyllnder and fed through the tvringer in the ordinary fashion. ln case one oi-the articles of clothing being passed through the vvringer should Wrap", around the Wringer rolls, as sometimes happens,tlie operator grasps the liever ,94, and moves the saine to engagement vvithlthernotch 97 Where the vvringer rolls 72, ''tvill .rotate in a reverse direction, so that the` entanglingclothing may he disengaged. l y .he ivringingoperation may he` continued until all of the clothing in the cylinder 29 has heen operated upon -loy `said wringer,

when its controlling lever is again inove to neutral position. novv he introduced into the cylinder 20, its door 26 again replaced, the lid l()e closed,

, when the operator may again move the lever that the clothes receiving cylinder 20 is lal-v Ways brought to a position of rest vvith its top horizontal Wall in an uppermost position,

owing to the location of its supporting and driving connections with reference to its center oi gravity, Another advantagey is that with the structure shown, the bracket castings and all oi' the driving gearing carried thereby together with the inotor may he assembled before it is introduced and attached in place "Within they gear case or compartmentprovided` therefor. A further advantage exists in the tact that the entire assembled gearing is located in a plane within the, upright vertical plane of the front legs ll, lla, therehy inclosingv all parts so that less damage is liable to occur vvhen in shipment. Another advantage is apparent vfrom this construction. 'lhe most usual Way to shiftthe support as a Whole shout, when through with the saine, or when starting in with a Washing, is to push it forwardly, with the hands of the operator grasping the rear top edge ot 'the support. lleretofore, gearing for similar purposes have generally been located outside of and horizontally beyond the base yprovided by the legs of the support or tub, and in so moving the support from place to place, upon engagement of the casters on the front legs, with some obstruction, a short push at the rear of the machine always has caused tipping over. With the construction as shovvn and described in the present invention, the entire weight ofithe gearing is within the hase of the support, therefore 'this danger ol tipping over is obvia-ted.

While in describing my invention l have referred to certaindetails of mechanical construction and arrangement of parts, l do not Wish to linn't myself thereto, except as inay be pointed Vout inthe appended claims.
