MECHANICAL MOVEMENT.

Application filed June so, 1915. Serial No. 37,135.

- To all whom it may concern:

Be it known that I, FRIEDEMAN R. JAEGER', a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mechanical Movemerits, of which the following is a specification.

My. invention pertains to washing-machines in general, but relates more specifically,--but not exclusively, to those appliances of this character having a rotary-drum adapted to contain the clothes to be washed, which is revolved alternately in opposite directions a predetermined number of times. One of the objects of this invention is the provision of a washing appliance of this character wherein the door or doors of the drum will always be brought to a definite ing, thedevice being supplied with accessible position Whenever the movements of the drum are stopped, regardless of which direction of rotation of the latter has occurred just previously to such stopping.

A further aim of the invention is the provision in an appliance of-this character facilitating the insertion of the drum in its casing and also its removal from such houssimple means for coupling and uncoupling the drum to its operating-shaft.

- Another purpose of the invention is the construction of the drum in such a manner as to facilitate the showering of water on theclothes contained therein during the actuation of the drum.

The accomplishment of these and other objects of the invention will be appreciated .by those skilled in' this art from an understanding of the construction and operation of a preferred embodiment of the same illustrated in the accompanying drawings form-' ing a part of this specification and throughout the various views of which like refer-.

ence' characters refer to the same parts, together'with the following detailed description of such mechanism.

Referring to these drawings it will be ob- 4 served that:

Referring to the drawings, it will be observed that the appliance comprises a framework of suitable construction composed of with casters or rollers 11, 11. These various legs are connected together by horizon tal cross-bars 12, 13, 14-, and 15, in any approved or suitable manner. portion of the frame has mountedtherein-a fluid-tight casing 16 with a rounded or semicylindrical bottom 17, the upper edge of the casing being provided with a suitable flange-part 18 adapted to receive the mar-' ,ginalportions of a removable cover 19, all 'as is clearly illustrated in Figs. 2 and 3.

clearly illustrated in Fig. 5.

The opposite end-wall 24 of the housing has a casing 25 mounted thereon, or rather secured by means of bolts 26, 26, to the crossbars 13, 1-1. This smaller. casing 25 has a bearing 27 (Fig. 2) fora short-shaft 28 which extends through the'housing, and inside the latter it is provided on its end with a square socket 29 facing inwardly, the inclined upper- walls 30 and 31 of such socket being partially cut away, as is clearly shown in Fig. 2.

The upper -a plurality of legs or posts 10, 10, equipped drical in form and is desirably composed of sheet-metal provided with a plurality of perforations33, 33. Such drum also has two mating door- sections 34 and 35 liinged to the drum at 36 and 37, their adjoining edges being adapted to be clamped or held together by any suitable form of fastening- -appliance 38. Inside, the drum has a plurevolution, as they emerge from the water,

they pour or shower their contents through the apertures 40 on to the clothes in the drum, in this way aiding the cleansing operation. These gutters also act somewhat as distributers for the clothes in the drum, and, to a certain extent, perform the functionof rubbers.

, This drum at one end, by means of a spider 42, has secured thereto an outstanding stub-shaft or trunnion 43, on which is mounted one arm 44 of a drum bail 45. The lowerend of arm 44 has an apertured hub or bearing 46 receiving the trunnion of the drum, and it also has two cam-lugs-4.7 and 48, the former being adapted to co'ciperate with the cam surface 23 and the latter adapted to co-act with the edge of the flange or rib T he opposite end of the rotary-drum has a spider 49 mounted thereon having an outstanding cylindrical-shaft 50 on which the companion arm 51' of the bail is adapted to rock, and, outside of such arm, shaft 50 is equipped with a square or angular block or lug 52 adapted in the operative condition of the device to snugly and neatly fit inside of the socket 29, so that the rotation of the latter will be transmitted through the part 52 to the drum containing the clothes.

The operation of this part of the appliance occurs substantially as follows:

Assuming that the drum 'has been remfived from the housing for cleaning, that it is to be returned to the casing for the reception of soiled clothes to be .cleaned, and

that the drum doors 34 and 35 have been closed and locked in such condition, the operator, by means of, the bail 44, 45, 51 in an upright condition lowers the drum into the housing containing a suitable supply of.

soapy water. During this lowering the boss 46 slides down the passageway between the vertical portions of the flanges 22, 22, on to its lower curved supporting-end, and the square block 52 descends into the socket 29 by reason of the cut away portions ofthe parts 30 and 31. Then the bail is swung from its upright or vertical position into the inclined position shown in Fig. 8, and during this movement cam 47 co-acts with cam 823 and cam 48 coiiperates with the edge of flange 22'so as to bodily push the drum and its associated parts axially toward stationary because of itspivotal engagement with the supports .or trunni ons of the drum.

The mechanical means for rotating the drum and reversing the direction of such rotation will now be described. a

On the lower portion of the machineframe, an electric motor 53 is mounted, and the rotation of its horizontal shaft is trans mitted to the vertical shaft 54by means of suitable gearing inclosed in the housing 55. The upper housing 56 contains bevel gears, whereby the rotation of shaft 54 is transmitted to a shaft 56 accommodated, in a cas-' ing 57. Inside of the boxing 25, shaft 56 loosely has mounted thereon the two bevel pinions 58 and 59 each equipped on its .the wall 24, carrying the block 52 fully inner face with one element of a clutch-memtion through the clutch 65, 60, and thepinion 58. On the other hand, if the sleeve.

is slid in the opposite direction, shaft 56 -will rotate gear 62 in theopposite direction through the co6perating clutch-mechanism 66, 61, and the bevel-pinion 59.

In order to bring about such automatic shifting, the device is provided with the following specified instrumentalities.

An arm 67 equipped at its upper end with a handle 68 is fulcrumed at 69 and its central portion is bowed or curved at 70 so as to extend part way around a central portion of the sleeve 64 of reduced diameter, whereby swinging of the arm will slide the sleeve on the part .63. Lever. 67 has an arm 100 pivoted thereto at 101, such arm carryinga rocking pin 7 2 through an aperture of which a rod 74 is adapted to slide slightly, the

upper sharpened end of the rod rockingly fitting in a cavity 75 in thecasing 25. A

coil-expansion spring 76surrounds rod74 30 I the arm 81 is out of contact with thetail 82 plete revolutions in and bears at its opposite ends against the casing and pin 72. As is shown, lever 67 is slotted at 71 to permit the pin 72 to extend through the lever. Gear 62 is supplied with a pin 77 normally spring-pushed toward the machine proper out of conflict with the pin 72, but capable of'being ad vanced so that during the rotation of the gear 62 it will engage the pin 72 for a purpose hereinafter indicated.

The housing 25 also has pivotally mounted ther'ein on a stud-shaft 80, a notchedwheel. 78, the notches of which cooperate with a pin 79 on the rear face of the gear 62', the outer curved faces of the teeth of such notched element cooperating with the hub 62 of gear 62, the face of such hub opposite the pin 79 being cut away at 62 to permit turning of the notched-wheel 78, these parts in effect constituting a Geneva movement. During each revolution of the gear 62 the pin 79 by co-action' with the notched-wheel 78 turns the latter one-sixth of a revolution, rotation of the notchedwheel at other times beingprevented by its co-action with the hub 62*. This notchedwheel 78 hasas a part thereof or secured thereto a cam arm 81 adaptedto coiiperate with the depending tail 82 of a cam 83pivoted at 84. Under ordinary circumstances and the cam 83 by its own weight and the action of a depressing spring'83 is down out of the path of travel of the springpressed pin 77. When, however, the gear 62 and the clothes-drum 32 have made six com- 81 will engage the tail 82 and swing the cam 83 up into the path of travelof the pin 77, projecting the latter forWardlyso that in its rotary travel it will engage .the pin 72, swinging the latter to one side of the center of the lever 67, whereupon the expansion of the spring 76 will automatically shift the arm 67 so as to disconnect one pair of clutch elements and clutch together the other pair, bringing about a quick reversal of rotation of the gear 62 and the drum.

Then the drum and the gear will make-six complete revolutions in the opposite direction at the completionof which cam 83 will again be raised. projecting the pin 77 in,

such a position that during its travel it will shift the pin 72 to the opposite side'of the lever 67, and bring about another quick reversal of the direction of rotation of the gear and drum, and thisaction will continue uninterruptedly until the operator wishes to stop it.

The top of the casing 25 is supplied with a curved rib 85 which. has a central lockingnotch 86 and the handle 68 is supplied with 'a spring-pressed locking-pin or rod 87 nordownwardly by a spring 88 mally pressed.

This rod 87 has a latinside of the handle.

one direction, the arm stop the movements of the machine, the operator merely swings the side pin 89 so as to bring it into register with the vertical portion of the slot 90, and since, under ordinary circumstances, the handle 68 will be at one side of the center, the rod 87 will remain on the part 85 and slide thereon until the handle is shifted to central position automatically, whereupon the freed locking-rod 87 descends into the notch 86 and locks the handle and arm 67 in vertical neutral position, both clutches then being inoperative so that the rotation of the gear 62 and drumimmediately ceases.

To start the rotation of the drum,the operator lifts the side pin 89, turningt into the angle portion of the slot 90, and the arm 67 responding to the action of the spring 7 6'will render one or the other of the clutches operative and then the machine will conany attention. to the stopping of the'drum,

it being merely incumbent upon him to operate the finger or side pin 89 as described above and the machine will automatically do the rest. Movement of the drum beyond the desired position of rest is prevented by reason of the fact that the pin 77 cannot pass the pin 72 which is held from further movement. 1

Having described this desirable embodi ment of the 1nvention,-it will be clear to I those skilled in this art that many minormechanical changes the sacrifice of any ofits substantial benefits and advantages.
