'ing mechanism for both rotating the washing cylinder and operating the clothes wringer.

In order to obviate the severe manual labor required to operate washing machlnes machinea motor, preferably an electric one, and driving mechanism actuated by the motor, and to utilize the motor also for operat ing the clothes wringer, which convenience requires should besupported upon the machine in position to pass the washed articles therethrough as they are removed from the machine.

An ob'ection to power-driven-wrlngers as heretofore constructed is that the direction of rotation cannot be reversed, and hence.

tangle them.

One of the objects of my invention is to provide a washing machine with a motor "mounted beneath" the machine without danger of injury from leaking water, the motor being supported by means which also contribute to the strength of the supporting frame of the machine.

Another object of my invention is to provide simple and efiicient drivlng mechanism a conveniently supported upon the'end of the machine for operatively connecting the motor with the washing cylinder and with the wringer, and whichmay be readily controlled to actuate either the Washing cylinder orthe wringers.

A-"further object ofmy invention 1s to provide aclutch mechanism intermediate the driving means and the wringer for operatable washing machine for household use, and theinvention consists in devising,

and in cooperatively combining, the com-' ponent parts of a cylinder washing machine and of the driving, mechanisms therefor, producing thereby a self contained, unitary machine, operatable without any other acccssories, except a source of electric current as it is available in households. in a washing machine, constructed according to my invention, the several mechanisms operating or driving its parts are designed and disposed in and between the parts of the machine, and housed in suitable casings, with the object in view to eliminate all danger of injury to the person" using the machine, or to the clothing, and so that after switching on" the electric current, the starting, operating and stopping of the machine requires merely the turning of a crank, pro vided with a handle located at a convenient point at the front end of the machine.

A washing machine, embodying the recited features' of my invention, is illustrated in the accompanying drawings, wherein Figure 1 is an end elevation-of my'improved washing machine. Fig. 2 is a front elevation partly in section. Fig. 8 is a section on the line 3 of Fig. 1. section on the line 4 of Fig. 1. Fig. 5 is a vertical section showing the lower part of Furthermore,

Fig. 4 is a the machine as viewed from a direction op- I posite to that of Fig. 1, this section being taken on the line 5 in. Fig. 2 looking in the direction of the arrow, and Figs. 6 and 7 are detail sectional views taken on the correspondingly numbered lines in Fig. 3. Figs. 8 'and 9 are details illustrating certain elements of the machine which may be identified by means of the referencenumerals applied to them.

In the particular embodiment of my invention which I have chosen to illustrateand describe, the washing machine stands on four legs at the'respective corners, each le comprising two sections 15 and 16, secure together b nuts 19. s shown in Fig. 5, the legs have an angular cross section and an upwardly projecting tongue 17 from the lower section 16 fits within the angular groove in the upper section 15. I v

Casters are provided at the lower ends of the corner posts as shown in Figs. 1 and 2. Inasmuch as these form no part of the inmeans of the bolts 18 and the wall of the washing machine tank, within which is the rotatable washing drum 33.

vention claimed herein they need not be described.

A horizontal brace 28 is connected to and supported by the two end legs 15. Above this is the end wall 29 of the washing machine tank. Above the horizontal brace 28 is another horizontal brace 30 extending across between the two legs 15, and above this is an extension 31 of the end wall. The reference numeral 32 indicates the front The transverse brace 28 has a horizontal extension 34, on the under side of which is bolted the electric motor 35. The conductors 36 lead thereto from the hand swit'h 37, mounted on the end wall 31 of the washing machine tank.- The conductors 38 lead from the screw socket 39 to the switch 37.

The motor shaft 40 carries agear pinion 41. A stud 42 projects from the cross brace 28, to which it is attached by the riveted head 43. On this stud 42 is rotatably mounted the hub 44, from which the spokes 45 radiate to the internally geared rim 46,"

which is engaged by the pinion 41. I annular plate 46 is attached to the spokes 45 by means of screws. A bearing block 47 is mounted upon the end of the stud 42, bemg secured thereto by means of the two set screws 48. A shaft 49 carries a gear pinion 50, which'meshes with the gear teeth 50 in the hub 44 of the main gear wheel 46. The shaft 49 has its end portion reduced in size as indicated by the reference numeral 51, and this is rotatably mounted in a corresponding socket in the block 47. A set screw 52, provided with a lock nut 53, is adapted to adjust the shaft 49 longitudinally. The block 47 has a flange 54 around the gear teeth 50.

The brace 30, which extends across the end of themachine, has'a projecting bracket 55, to which an extension member 56 is at tached by screws. Between the bracket 55 and the extension 56 is clamped a bushing 57 surrounding the shaft 49. A casing 58, having a row of holes 59, has its lower end resting on the bracket 55-56. The brace 61 is bolted to'the corner of the machine, and a bracket integral therewith projects up and ends in a cap 62, which is attached to and supports the upper end of the casing 58. Inside of the end wall 31 of thewashing machine is a plate 63 from which a tubular extension63 projectslaterally, constituting a journal bearing for the shaft 64, to the end of which is fixed a gear pinion 65 by means of the pin 66. The collar 68 is loosely mounted on the shaft 49, and has the gear pinion 67 at one end thereof in mesh with the pinion 65. This collar 68 has ratchet or clutch teeth. 69 adapted to be engaged by the opposed teeth 70 on the flanged sleeve 71. This sleeve '71 has sliding engagement with the shaft 49, but is forced to rotate therewith by means of the key 71. The fork 72 (see Fig. 7) engages the sleeve 71 between the flanges at the ends thereof.

the casing 58, the parts being held firmly in place by means of the coil spring 77 and the lock nut 78. The shaft 73 has an offset at 79 corresponding to the eccentric mounting on the disk 74. Between the ends of the members 80 is fastened a plate 82, by means; of bolts 83, the ends of the plate resting against the sides of the casing 58, and thus holding the fork 72 against rotation-around the shaft 49. On the end of the shaft 64 is a gear wheel 84, which engages a train of gears mounted on the plate 85, that connects with the studs 86 to rotate the drum 33.

Within the cap plate 62, at the upper end of thecasing 58, is an adjustable bushing 87, which engages the upper end of the shaft 49. The pinion 88 is loosely mounted on the shaft 49 against the washer 89. Another opwill be explained presently. On the opposite end of this shaft 94 is fixed a beveled gear wheel 96, which is in engagement with both the beveled gear pinions 88 and 90. The opposed ends of the beveled gear pinions 88 and have clutch teeth 115 and 116, between which is the flanged collar 117 with opposed coacting clutch teeth at its ends. This collar 117 has non-rotatable but slidingengagement with the shaft 49 by means of the key 118. Within the flanges of the collar 117 is the fork 98, from which the two members project having a slot 99 between them. There is a slot 97 in the casing 58, within which the members 100 are adapted to reciprocate; thus the fork 98 is held against rotation about the shaft 49. A disk 101, journaled in the casing 58, has a shoulder 102, from which extends a crank 107 with a handle 108 at its extremity. Eccentrically'mounted in the disk "101 is a shaft 103, which has an offset 104 corresponding to the eccentricity of its mounting, the end of the shaft 103 beyond the offset 104 being journaled in the casing wall and the parts being held closely in place by means of the coil spring 105 and the lock nuts 106. The shaft 103 lies in the slot 99 of the fork 98.

The clutch 95 on the end of the shaft 94 is adapted to engage a transversestud 111 on the end of the drive: shaft 110 of the wringer 112. This wringer is adapted to be attached to the upper front edge of the.

to enable the rotation of the wringer rollers to be instantaneously reversed, is claimed water is preyented from running down through the motor.

Assuming that the clutch 6970 i s disconnected and that the crank 107 has the intermediate position shown in Fig. 2, whereby the sliding collar 117 will be in an intermediate position with ,its clutches disengaged at both ends, then it will be apparent that when the electric motor 25 is setto running by properly throwing the switch 37, the only effect will be to idly rotate the shaft 49 by means of the intermeshing gears 41 and 46. When it is desired to start the washing drum to rotating this is accomplished by throwing the crank 75. This causes the eccentric shaft 73 to push'the clutch teeth 70 into engagement with the clutch teeth 69, and thus the'rotation of'the shaft'49 is communicated through the collar 71 to thegear pinion 68. 'This drives the gear wheel 84, and thence through the intermediate train of gears mounted on the plate 85, the movement is communicated 'to the drum 33.

When it is desired to start the wringer 112 :this can be accomplished by rotating the crank 107, which will cause the eccentric shaft 103 to shift thecollar 117, thereby causing the clutch teeth at one end of the collar to engage the clutch teeth- 115 or 116 on the respective gear pinions 88 or 90. Thus it will be seen that the rotation of the shaft 49 will be communicated through the collar 117 to .one or the other of the gear pinions 88 and 90, thus rotating the wringer rolls. The direction in which the wringer rolls are rotated will depend upon which clutch 115 or 116 is engaged by the collar 117, and this will depend upon the direction in wh'ich the crank 107 is turned from its intermediate position shown in Fig. 2.-

Thus. it will be seen that the wringer can be driven forwarder backward orc'an be instantly stopped at will.

The transverse brace 30 in connection with the parts 55,56 and 57 forms a support for the shaft 49 and for the lower end of-the gear casing 58. This brace 30 also support for the two eccentric shafts 73 and 103 and also affords-guiding means for the forks, which are reciprocated by these shafts. The holes 59 in the casing 58 facilitate oiling the gears.

I consider the reversible wringer driving mechanism a feature of decided lmportance.

If garments become caught in'the wringer rolls, the latter may be quickly stopped and reversed, thus withdrawing the garments without tearing them or without making it necessary to dismantle the whole ,wringer in order to remove them.

The lower part 61 of the corner bracket 606162 has a right angle cross section fitting around the upper part of the corner post 15. The intermediate part 60 carries .a journal bearing for the wringer driving shaft 94, and the top part 62 supports the casing 58 and also carries the adjustable thrust bearing member 87 for the shaft 49. The transverse brace 28-34 has a right angle cross section, which gives it great strength and at the same time affords a suitable support for' the motor 35, the flan es 114 causing any drip water to fall down eside the motor instead of upon it.
