`This washing machine comprises generally, a tub, a plunger mounted in the tub to reciprocate vertically therein and move about a vert-ical axis, and actuating mechanism mounted on the frame and yconnected to the plunger to consecutively and intermittently reciprocate it and move it about its vertical axis when the plunger isldown.

Serial No. 448,459.

The plunger also preferably has a partial movement as a half oscillation in a return direction, when the plunger is up off the clothes for a purpose to be hereinafter described. Y l i The machine also comprisesawringer normallyarranged within the frame and mounted to be shifted above the frame when in use. v

'1 designates the frame which is here shown as rectangular in plan and includes corner posts 2 and aV bottom or pan 3. lThe frame is carried on suitable wheels or ycasters 4. The top of the frame is provided with acover 5 and generally, the sides of the frame are enclosed by panels or a cabinet. of

any suitable construction, one of the panels or sides of the cabinet being a door 5a.

6 is the tub mounted in the frame, the tub being circular in form and preferably having a roughened or corrugated bottom 7 and also having the lower part of its cylindrical wall vertically corrugated as at 8. 6a is a cover for the tub. The tub has a suitable valve controlled outlet.

9 is the plunger mounted to reciprocate vertically in the tub and also to rock about a vertical axis.

This plunger comprises generally, a central tubularfbody 10 for telescoping on a post 11 best seen in Fig. 5 rising from the bottom of the tub, and outwardly or radially extending blades 12 having vacuum cups 13 in the form ofchannels extending radially relatively to the body 10. The blades l2 agitate or slosh the Water. Hence the plunger, owing to the vacuum cups or channels, has a vacuum washing action as well as a pounding and rubbing effect on the clothes.

Theplunger is also provided with air ducts leading from the cups 13 lto partly relieve Ethe vacuum therein and as here illustrated these ducts 15 lead upwardly along the tubular body 10 to the upper partof the body 10 above the high Water mark, and the upper ends are closed 1by a valve which is here illustrated as a floating-ring or washer 16' around the body 10 and resting on the upper ends of the ducts 15. l

The plunger may be constructed in any suitable manner but preferably it consists of @erwin Parts., thatubular body 10, an@

triplicate sections 18 which form the blades 12 and cups 13. Each section 18 as seen in Fig. 9 consists of halves of two different and adjacent cups and blades 12. When these-V sections are brought together. complemental halves of the vacuum lcups 13 and blades are brought together to. form th-ree cups and blades 12. Thus the blades are of double thickness of sheet metal.

As seen in Figs. 10, 11 the body 19 of the plunger may widen or be formed conical at it`s`lower`end at 2O to form a concen- 5 rocati-ng movement thereto, and the lother being connected to the plunger to transmit rocking movement thereto, and actuatmg means for effecting such movements of the motion transmitting parts.

As here illustrated, the plunger 9 is provided with a central hollow rod 24, Fig. 5 depending into the tubular hub or body 10 thereof from a head 25 at the top of the body 10; and the part within the post 11 and body 10 for transmitting a rotativeor rocking movement to the plunger, comprises a rod or tube 26 i extending upwardly through the post and telescoping with the rod 24, both rods being shaped so that the rod 26 turns the rod 24, andthe rod 24 can slide relatively to the rod 26.

As here shown', these rods 24, 26 fit one within the other and are non-circular, as square, in cross section. The rod 26 is here shown as carried by a wheel as a gear 27 mounted in the bearing or socket 28o'n the casing 22 beneath the tub and in linev with they post 11, said rod being fixed to the hub of the gear 27. Also, preferably, a sec- 0 ond tube 29 projects from the hub of the y, the telescoping rods .24 and 26. This. rod

gear and rotatably fits the inner bore of the post 11.

The motion transmitting part for reciprocating the lplunger comprisesa push rod 30 extending axially through the gear 27;

30`is also preferably a tube and has a plug 31 at its upper end pressing against the in` ner face-of the plug or cap 25 at the top of the body. 10 of the plunger 9. As here shown, sin annular plug 32 is inserted in the upper end of the body 10'l of the plunger 9 around the rod 2,4, and the capI 25 is mounted onA the upper' end of the plunger land is Secured to the plug 32 by screws'. A Suitable oil cup 34 is provided on the cap from whence a duct 35 leads to supply oil to the wearing surfaces between the tubes 24 and 26. The cap is also provided with .a buffer 36 against which the rod 30 thrusts. Also suitable air holes 37 are provided in the plunger body 10.

The actuating means for the motion transmitting parts 26, 30 comprises a single actuator, and means for transmitting the plurality of movements of the actuator' to such parts and hence to the plunger. The actuator as here shown comprises a member 38 mounted upon a shaft 39 journaled in the casing 22 and having points or teeth 40 for coac'ting with a pusher or lifter 41 to which the lower end of the push rod 30 is Secured. During upward movement of the pusher or lifter 41the plunger 9 is raised, and when the lifting force of the actuator 38 is discontinued, the plunger 9 moves downwardly by gravity. As here shown, the actuator 38 which is discoidal in general form is provided with a plurality of cam points or teeth 40 coacting with one or more teeth 44 on the pusher or lifter 41 soy that when the pusher or lifter 41 is raised a predetermined amount the teeth 40 will pass by or clear the teeth 44 of the pusher or lifter 41 and permit the plunger 9 to drop. The lifter 41 is here shown as movable along a vertical vguide rod 45 suitably supported within the .casing 22. The actuator member 38' is also provided with a peripheral cam 46 Ahaving lateral deflections 47 and dwell lor straight portions 48, and the motion of this camy 46 is transferred to the plunger 9 to rock the same by suitable Ineansof the lever 49 pivoted at 50 within the casing 22 at 'one end, and having asegment 51, Fig. 7 at its other end and followers 52 between its ends coacting with the cam 46. vThe segment` 51 meshes with teeth of the `gear 27. The greater portion of the periphery of this gear 27 is blank or unprovided with teethl and engages the wall of the socket 28 on the top of the casing 22. The teeth 40 of the actuator.38 and the active portions or deflect-ions 47 and dwell portions 48 of the cam 45 are so arranged or timed that theycome into action consecutively', that is, the followers 52 ofthe lever 49 coact with the dwell portions 48 when the teeth 40 are raising the lifter 41.

Butter means is provided for preventing droppingof the plunger 9 on the bottom of the tub when no clothes are in the tub and also means is provided for holding the llfter 41 whenyin its lowermost position so that the plunger ispotl" the vbottom of the tub. The buffer is here shown as a lever 53 pivoted by a'pin-and-slot at 54 within the casing 22 and also pivoted at 55 to the lifter 41.

This lever 53 extends along one side of the actuator 3 8 and is formed with a camslot 58 are shown in their position occupied just 56 in its face opposed tothe actuator 38.A vThe actuator 38 is provided with a. pin or follower' 57 projecting from one side thereof, which enters the cam slot 56 and rides along the same during downward movement ofthe plunger. The lever 53 with its cam slot 56 is arranged so that its receiving end passes into the arc or orbit of the follower 57 after the teeth40 of the actuator have cleared the teeth 44 ofl the litter 41 and passes through the slot during downward movement of the plunger by` gravity and positively returnsy the lifter and acts as a timer or synchroniser between the actuator 38 and the lifter 41.

The means for determining the lowermost position of thelifter 38 so as to hold the plunger olf the bottom of the tub in order to avoid liability of the operator dropping the plunger 9 on the bottom of the tub when replacing it on the post, consists of a locking flange 58 on one side of the actuator 38 and arranged to enter the slot 56 just behind the follower or pin 57 and support the lever 53 and hence the litter 41 until the first tooth 40 ot the actuator 38 engages the teeth 40 of the lifter.

The flange 58 or a portion ,thereof passes Ithrough the Aslot 56 ofthe ari/n 53 when the plunger or the lifter 41 is in its lowermost position and prevents thelifter 41 from assuming a position low enough to permit the plunger to strike the bottom of the tub. The flange is long enough to havev some part thereof in the groove when the teeth-40 are out of engagement with the lifter 41..

In Figure 2, the actuator 38 and flanges after the first tooth 40 engages the lifter 41. .l ust prior to thistime', the rea-r end portion of the flange is in the slot 56-and, hence, supports the lever 53 and the lifter 41. The foremost tooth A40 `engages the lifter 41 as the rear end of this flange 58 passestout ot' the slot 56 of' the lever f y As best seen in'Fig. 6, the slot 56 in the lever 53 is openen its side toward the actuator 38, and the groove or slot 56 is formed with an arc-shaped portion of the same curve as the flange 58, which arc-shaped portion is concentric with the actuator 3 84 when the litter 41 is in its -lowermost position, and said slot is also formed with an angular portion at its upper end terminating in a mouth through which the pin or' roller',` 57 enters. The lever also formed with a passage or slot 56, Figs. 6 and 7, in line with the upper end of the arc-shaped portion of the# slot 56', the passage 56 being the entrance for the flange 58. rl `l1e flange 58 does not pass Athrough the angular portion of the slot or groove 56,'but this flange is Alocated a sufcient distance behind the pin or roller 57, so that, when the lever 53 has'` been carried upwardly by the lifter 41 to its-full extent the pin or roller 57 is in line withy the mouth of 'such angular portion and moves thereinto. Immediately upon the teeth 40 of the actuator 38 passing out of mesh with the teeth 44 of the lifter, the lifter drops from the position shown in dotted lines, Fig. 2, to that shown in full lines, such dropping being/permitted by the arc-shaped formation or widening of the upper wall of the angular portion of the slot 56, and the lifter -drops to' its lowcrmost position and away from the plunger 9 in the tub. When .in this lowermost position the passage 56 1s 1n line with the locking flange 58, and the locking flange 58 passes through the passage 56 and through the arcshaped portion of the slot 56, and thus holds the lifter from dropping far enough to permit the plunger 9 to strike the bottom of the tub after the roller 57 has passed out ot' the lower end of the slot 56 and also holds the teeth 44 of the lifter in position to regis- -ter with'the teeth 40 of thel actuator 38,

when said teeth 40 are carried by the actuator back into lifting position. The plunger 9 "is lifted only by the lifter' and falls by gravity, for the reason that the rod 30, Fig. 5, merely thrusts against the lower end of the rod 24 of the plunger and is moved away from the same as the lifter 41 drops when the teeth 40 of' the actuator 38 is moved out of mesh withthe teeth 44 of the lifter, the widened part of' the angular portion of the slot 56v permitting the litter to drop relatively to the plunger in order that the plunger may` conform to the depth or thickness of the clothes in the'v tub. This plunger is comparatively heavy and it is the weight thereof and the scrubbing action that cleanses the clothes. The lifter therefore. is always free to drop when the teeth 40 of the actuator 38 clear the teeth 44 .of the lifter, and such dropping brings the arc-shaped portion of the slot 56 and the passage 56 into concentric-"relation with the flange 58, so that, the flange 58n can enter the arc-shapedportion ot the slot 56 through the passage 56 and hold the lifter high enough to prevent the plunger 9 from striking the bottom of the tub (if the tub is empty) when in 1tsvlower most position after the roller 57 has passed out of the slot 56. The flange 58 therefore, acts to keep the teeth 44 of thelifter in position to mesh with the teeth 40 of the actuator Q38, and also to prevent the plunger fromA striking the bottoni ,of the tub, when there are no clothes in the tub, and they lifterr ofthe' wringer. Either one or the other of the Gears 82,

| and the top passed out of the slot 56, and, so that, the plunger will be limited in its dropping movement by the end of the rod 3.0 engaging the end of the rod 24 before the plunger strikes the. bottom of the tub.

The actuator 38 is operated by a shaft 59 journaled inthe casing 22 and having a gear 6() thereon meshing with a gear 61 on the shaft 39. The shaft 59 is also lconnected to a suitable motor 62 here shown as through a worm wheel 63 mounted on a shaft 59 and meshing with a worm 64 on the motor shaft 65 which is journaled in the casing 22.

The worm wheel 63 may be connected to and disconnected from the shaft 5 9 by a suitable clutch 66 slidable on the shaft 59 into and out of engagement with the clutch face on one side of the worm wheel 63. This clutch 66 is shifted by any suitable means as a rod r67 extending through the casing 22 and terminating in a handle 68 near the top of the frame.

The casing 22 is oil tight and hence may be partly 'filled with oil. Thus, all wearing parts are oiled from aL single source with the exception? of the sliding parts within the post 11 which are oiled from an oil cup up on top ofthe plunger, and also with the exception of the motor bearings which are provided with oil cups. 'y

As will be understood by those. skilled in the art, this arrangement by which the washing machine mechanism can be supplied with oil which will last indefinitely, is highly advantageous.

69, Figs. 1 and V4 designates the wringer which is provided with a supporting bracket l70 on one end thereof. This bracket includes a tubular part mounted to turn or swivel about a non-rotatable sleeve 71 which in turn telescopes lwith a shaft 72 rising from and journaled in agear box 73 suitably supported by the frame. This sleeve 71 also slidably fits. a. bearing in a bracket 74 supported by the frame between the gear box of the frame.

The rolls 75 of the wringer are actuated from the shaft 59 in any sultable manner as by a. shaft 76 journaledat one end in a bearing. in the casing 22in alinement ywith the shaft 5 9 and at its other end in the gear box 73, the shaft'72 before mentioned, intermeshing gears 77,v 78, located in the gear box 73 and mounted on the shaft 59 'and the lower end of the shaft 72, a shaft 79 within the sleeve-71 and telescoping with the shaft 72, and gear 80 on the upper end of the shaft 79 within a gear box 81` carried by the bracket 70 and meshing-on opposite sides of its axis with gears 82, 83 mounted on' the shaft or axle 84 of one of the rolls 83 may be connected -to the shait 84 by @sans ef a duwt' malwares; S Of-anywell 'suitable construction including a shifter rod 87 extending upwardly within the frame-to near the top thereof.

lThe telescoping shafts 72, 79 are noncircular or square in cross section and the gears 78, 80 have their hubs journaled in suitable bearings formed in the gear boxes 73, 81 respectively.

The wringer 69 and its sleeve 71 is shiftable vertically of the shaft 72 from a position below `the top of the frame into a position,above the same, and as here shown, the bracket 70 and the sleeve 71 slides vertically of the shaft 72, and in order to permit this movement the shaft 79 telescopes within the shaft 72.

When the Wringer 69 is in its lowermost position as shown in Fig. 1, the bracket 70 rests upon a bracketl 74 and when in its uppermost position rests upon the upper edge of the frame at the corner thereof, In thev embodiment of the invention shown in Figs. 1 and 4 a base plate 88 forthe bracket 70 is provided at the upper end of the sleeve 71, saidplate 88 being mounted to swing about the sleeve 71 and over the upper edge v of the frame at the corner thereof, and thus support the'wringer in its position shown in Fig. 4. The plate 88 is provided with aV groove formed by shoulders 89 for receiving the upper edge of the frame.

the plate 88. The wrnger-is also provided with a suitable quick release mechanism including a lever or levers 94 which when the tensionis on the rolls project upwardly, and

Y when the wringer has been demounted or placed in its position shown in Fig. 1, project high enough above the top of the frame to prevent closing of the cover 5 unless the lever or levers 94 are movedto lie flatw1se and hence release the tension on the rolls.

The construction of the quick release mechanism aside from the levers 94 which project upwardly above the top of the frame to prevent closing of the cover, form` no part of this invention and 4hence description thereof is unnecessary.

The wringer is comparatlvely light 4and can be very readily lifted to its upper pos1- tion, Fig. 4 or lowered to withln the frame into the'position shown in Fig. 1,-b ut 1f desired suitable means may 4beprovided for lifting and lowering it.

In operation, upon throwing ofjthe clutch\. 6@ t@ ceenetthe warm Wheel 6?. te the-shaft ill) 59, the 'actuator 38 will be operated to first v lift the plunger 9 on account of the teeth 40 engaging with the teeth 44 of the lifter 41,

and after the teeth 4() have cleared the teeth 44, the plunger will drop by gravity, it being controlled in its dropping by the pin or follower 57 on the actuator 38 'bearing on the walls of the slot 56 of the buffer lever 53. Also, after the follower 57 has moved out-of the slot 56 and before the teeth 4() prevent the plunger from striking the bottom of the tub. Otherwise, when the teeth 40 pass out of engagement with the teeth 44 of the lifter 41, the lifter would drop farI enough to permit the plunger to strike the bottom of the tub. The flange 58 conforms in curvature to the slot 56 of the lever 53 and causes the lever 53 to be drawn upwardly so that its cam slot is concentric with the. center of the flange 58. i

During the reciprocation of the plunger,

the dwell or straight portions 48 of the cam 46 on the actuator. 38 engage `the followers 52 of the segment lever 49 so that thegear 27 is idle. However, when the reciprocation of the plunger 9 is completed and the plunger is in its down or lowermost position, the

active or deflected portions 47 of the cam v46 i engage the followers 52 of the cam lever 49 and rock this lever to oscillate the gear 27 and hence the plunger through the rods 24, 26.' The deflections 47 are so arranged that an oscillating movement overlaps the reciprocating movement and takes place when the plunger is up in order that the plunger when again moved downwardly will engage the clothes at a different place than before. Hence, the clothes are constantly being fed around the tub.

During the oscillation of the plunger 9 ythe clothes are scrubbed on the corrugated bottom and sides of the tub. During reciprocation owing to the vacuum cups at the bottom of the plunger, a vacuum washing' action is effected, and owing to the blades 12, a sloshing action takes c, place during the rocking of the plunger. Hence, in' this washing machine, vacuum pounding, scrubbing and sloshing actions are effected.
