' all whom it may concern:

' Gearing, of which the following is' a speci ticatio T1115 invention relates to gearing, and

machines of the motor driven type.

\Vashing machines of this type with which we have illustrated our improved gearing combined embody an outer casing, a washing element or drum within the casing, wringer supported on the machine, and driving gearing for the drum and wringer;

Since the drum is heavily loaded withclothes, and s ince it is necessary to impart to inorder to prevent twisting of the clothes,

supporting means therefore, on account ct the torque of the driving connections. [The driving mechanism is, moreover, necessarily somewhat complicated in order to perform its functions, and difficulty is, therefore, ex-

perienc'ed in properly alining the elements of the driving mechanism, and in properly lubricating theksame.

6 of the obiects of this invention, there t ue. is to provide a Washing machine in which the driven elements and the driving gearing are so supported as to insure correct alinement, and so as to prevent the incidental strains from affecting the casing.

I Another obj eat is to provide novel driving gearing Whichis arranged as a unit, so as to be readily removable from the machine, which is constructed to permit lubrication of parts, and which is positive and certain in its action, so as to prevent undue strain 3 on and breakage of the parts.

Anotherobject'is to provide a washing machine which is simple in construction and operation, cheap tomanufacture, and which .apossesses great strength and durability consistent with lightness in weight,

Further objects will appear from the detail descriptiontaken in connection with the accompanying drawings, in Which: Figure 1. is a rear elevation ofa machine embodying this invention;

Referring to the accompanying drawings, and more particularly, to Figs. 1, '2 and 2 1 designates the body of a casing having.

ends 2 seamed to the body to'form a selfcontained structure, that is, to form a structure which is'c'omplete in itself. A pair of and frames 3, of substantially circular form,

and l: ing each an inwardly projecting flange -1 and radial arms 5 running to a center support 6, engage the ends of the casing' and frames are of pressed metal, the flanges and the ribbedarms :5 resulting in a structure which has great rigidity compared with its weight. thereto a pair of legs 7, each leg, at its point .with the flanges 4 taking over the, casing,"

so that the ends of the casing will be termi-' nally supported by these end frames. These Each end frame has attached 1 of engagement with the frame, branching laterally, as shown at 8, and being flanged, as shown at 9, to embrace the end frameand form a rigid connection therewith. These legs are removably attached to the end;

frames by means of bolts 10. Rods 11 and 12 connect these legs at their upper and lower ends. Brackets 120 are attached to the end frames, these brackets being also preferably of pressed metal construction and supporting a beam 13 which is rigidly secured in position between the brackets by a at their upperends.

- tension rod 14 passing, through the brackets? and thus firmly connecting the end'frames Arranged within the casing ana "ii trashed.-

to the center supports 6- are bearing brackets 16 of a drum 17',this drum being preferably 15, which removably support the trunnions constructed and removably supported. A-

2 cover 18 is mounted on arms 19,8which in turn are pivoted on the bearingstl'5- at 20, sothat the-cover can swingback and forth p to permit access to and removal of the drum.

The casing is provided with a drain cook 21;

- Mounted on a bearing 25 attached to the center support 6,. on-one of the end frames,

as a stub shaft 26 w i has a e e v Fixed to this shaft is a disk 27 having a circular-recess-28 terminating in a stop 29, and recessed as shown at 30. This disk has a hub 31, upon which is mounted the hub 32 of a gear Wheel 33. This gear wheel has attached thereto a flange 34 provided with an axially projecting lug 35 Working in the recess 30. Springs 36 are located in the recess 28, and bear against the lug 29 on the disk 27, and the lug 35 on the flange 34. A flanged collar 37 fixed to the shaft 36 holds the parts in assembled relation.

A bracket 38 is attached to the le 7 by a bolt 39 engaging a slot in the bracket, and

40 mesh- 48, so that the housing is adjustable along the brackets, and nuts 42 on the bolts clamp the housing-in adjusted position. The shaft 49 of this driving gearing has a pinion 5O meshing with the idler 40. Mounted on this housing is a-bracket. 51 supporting an electric motor 52, whose shaft 53 has a universal coupling connection with the main drive shaft 54 of the driving gearing.

Referring now more particularly to Figs. 3, 4. and 5, the main drive shaft 54, which is mounted in bearings 55 in the housing, has fixed thereto aworm 56 meshing with a worm wheel 57. loosely mounted on a shaft 58 supported in bearings 59 in the housing. This-worm wheel'has clutch teeth 60 mesh in with clutch teeth on a clutch sleeve 61 sp injed to the shaft 58, and this clutch sleeve is shifted by a fork 62 mounted on a rock shaft 63 having an arm 64 outside of the housing, connected by a link 65 with a bell crank shifting lever 66 pivoted on the end frame 3. I

Loosely mounted on the'shaft 58 are a pair of sleeves 67, and in turn loosely mounted on these sleeves are bevel gears 68 meshing with a bevel gear 69 on the shaft 49, which sup ported in bearings70 in the housing. The sleeve 67 and the bevel gear 68 mounted thereon have-radially projectin lugs 71 and 72 respectively, and the lug 41 has fixed therein an arcuate Ibar passing loosely through the lug 72 and having mounted thereon a spring 74 between the lugs 71 and 72, a cotter pin 75 passing throughthe end of the bar keeping the parts together. A1:-

ranged'within the sleeve 67 are a pair of plungers 76,'the reduced ends 77 of which form clutch jaws. These jaws are projected by springs 78 bearin against the pins 76 and against'screws 79. lhe jaws 77 are adapted to be engaged by jaws 80 on a clutch sleeve 81, splined to the shaft 58 and shifted byan arm 82 pivoted at 83 on a bracket 84 fixed to the housing. The-arm 82 has integral therewith an arm 85, which in turn has joined thereto at 86 an arm 87.,'loosely passing through a swivel niember88 provided With lugs 89 engagin recesses ina bracket'90. A. spring. 91 positioned between a collar 92 on the arm 87 and the swivel member 88 ex 1 7 erts a pressure on the joint and serves to move the arm laterally in either direction when the toggle formed by the arms 85 and v 87 is broken as hereinafter described. J ournale'd between the bracket 84 and a bearing 3 lug projecting upwardly from the bottom of the housing is a worm wheel 93 meshing with a worm 94 fixed 'to the shaft58. This n Worm wheel has fixed thereto or formed thereon cams 95 and 97, adapted to engage a cam roll 96 on the arm 85. v Operation of the clutch sleeve 61 through the bell crank-lever 66 will operate to conneat and disconnect the shaft 58 with and i from the main drive shaft 54. Rotation of 9'0 the drive shaft ,58; will continuously rotate the worm wheel' '93'and its attached cam 95, and will also rotate the clutch sleeve 81., .Assuming the parts to be in the position shown in Fig. 3, in which the cam 95 moving in the direction of the arrow has shifted the arm 85 ton osition sothat the clutch sleeve 81 will be in midposition, this movement has straightened the toggle and placed the spring 91 under compression. Further movement of the cam will .move the arm 85 to the right, and a slight movement over the dead center position of. the toggle will break the toggle to the right, and the spring 91 will then act to quickly engage the clutch sleeve 81 with the jaws of the lower sleeve 67 and connect the lower bevel ear 68 with theshaft 58, thereby causing the clutch bevel gear, through its gear connection with the bevel gear 69, to drive the shaft 49. The no.

shaft 49 will be driven in that direction until the cam lug 97 engages the cam roll 96. This cam lug 97 will first operate to straighten the toggle and then move it over dead center in the other dijrection,moving the arm 85 to. the left, thereby placing the spring 91 1111-- der compression, and, after the toggle joint i has passed overdead centhr, the spring 91 will again operate to quickly throw the clutch sleeve 81 upwardly toward theupper 120, sleeve 67, to cause the jaws 80 to engage the jaws on this clutch sleeve and connect the upper bevel gear 68 with the shaft 58, thereby causing the shaft 58, through the gear conm- ctions 68 and 69, to drive the shaft49 in the reverse direction.

It will thus be seen that this shiftimg mechanism operates to positively retract the clutch shifting jaws and to yieldingly engage the same with a quick snap action,

' made between the gear through the springs v be bodily applied to the idler ported on the cross beam 13.

thereby resulting in a positive disengage merit and a rapid engagement of the clutch jaws, and'preventing wear on these jaws.

It will be seen that with this drum an alternating rotary movement, the gearing connection being such that-the drum 'is rotated a plurality of revolutions before reversing- The reversal of the heavy drum, of course, throws considerable strain on the driving gearing. It is for this reason t at the yielding connection between each of the gears 68 and its supporting sleeve 67 are provided. It will be seen that, upon engagement of"- a sleeve 67 with the clutch sleeve 81, the torque isjtransniitted through thespring 74, which compresses and thus takes up the shock at the point of reversal. This spring is, of course, strong enough to take the load Without undue compression. To still further take up the shock at the point of reversal, a'yielding connection is 33 and-the drum, 36.

to take up the shock, the gear teeth are obvious that the Fig. 8 could 40 by a simi' as additional cushions whereby all strains on avoided. It is, of -course, yielding connection shown in lar connection, I

such a construction is, there obvious.

The shaft 54 has fixed thereto a worm 100, which meshes with a Worm wheel 101 having a bearing in the housing, and provided with a stub shaft 102 hav ng a. universal joint connectionwith a shaft having a universal joint connection with the shaft 104 of the wringer driving gearing, which is mountedin ahousing 105. This wi-inger gearing may be of the construction as shown in- Patent No. 1,082,551. The driven shaft 106of the wringer gearing is connected" to drive the wringer 107 sup- The controlling arm for the wringer gearings is shown at, 108. It will thus be seen that the invention accomplishes its objects. A washing machine is produced which is simple in construction and operation. The casing and end frames, while of light construction, are entirely rigid, and in view of the fact that the casing is self-contained, and all parts supported from the end .frames instead of from the casing, this casing can be made ofthin metal. By mounting the driving gearing in a housing and by attaching thereto the niotor. this motor and housing can and'i'eplac parts of the gearing be removed to be accurately maehined without requiring excessive time for ining up the shafts and the bearings. It will be readily seen, by reference to Figs. 1

. mechanism means are provided for imparting to the departing These springs act and a detail description or.

103, in turn the drive shaft, a driven "nately to said driven shaft will be rotated alternately in ed as a unit, thereby enabling the.

and 2, that the gearing can-be readily disconnecting the moved as a unit by simply operating rod 65 and the shaft 103 at-their lower ends. The adjustable mounting of the bracket38, moreover, furnishes a quick means for alining and adjusting the'idler 40 with respect to the gear 50. By raising the gearin and the housing, this housing can be filled with oil and grease, so that thegearing can run in oil, thereby resultin in perfect and continuous lubrication. oreove'r, by mounting this unitbelow the casing, it is not only firmly supported, but any dripping of thereby preventing soiling. 2
