Referrin to. the drawings'by reference numerals, designatesithe main tub. It is riveted at 2 to a bottom. 3,- which rests on legs 4 and is provided with radial grooves 5 and a depression 6 having a pet-cock or valve 7 through which to empty the gasolene out from the machine; The tub is also provided with a cover 8 having a handle 9.

- Spaced within the tub 1 is a cylinder 10 having perforations 11 in its bottom and in the lower portion of its wall. Said cylinder has its bottom 1O fixed on acentral vertical shaft 12 whose lower end isjournaled in a ball-bearing 13 in the bottom of the tub, and the upper end is journaled in the leg of a T-shaped member 14, in whose upper portion and in bearings 16, 17 fixed onthe tub, is join-naled a horizontal operating shaft a pulley 19 so 'it may be turned by either: hand power or a belt where' motive power is available.

Patented Aug. 19, 1e19 V near which is journaled on the shaft an arm 21 having two

studs

22,23. 7 On the latter stud is journaled a combined gear wheel 24. and a small grooved friction pulley 25, Said pulley is adapted to engage frictionally the upper edge of the cylinder 10 and rotate it slowly since the gear 24 is larger than gear 20 which drives it by means of an idler gear 26 on stud 22.

gagement may be put out of action by supporting the free end of the arm 21 m a notch 28 of a support 29, which is pivoted at 30 to the tub and is idle whenleaning against a pin 31 fixed in the side ofthetub. 1

Slidably fitted on the shaft 15 and a featherkey 32 in same is a bevel gear havinga 3 set-screw 34 adapted to hold 1t either in mesh or out of mesh with a bevel fixed on the vertical shaft12. I L

Fixed on the shaft 15 are also two mutipinion 35

lated gears

36, 36*, each of which has its toothed portion turned towardthe side of Q the shaft 15 where the untoothed portion of Q the other gear is directed. Detachably'journaled on the shaft 15 is a frame 37 having vertical channel bearings 38, m which; are slidably fitted pounder bars 39 havmgeach a rack 40 arranged to be engaged by the adjacent mutilated gear, 36 or 36*. The lower end of each pounder bar is provided whose bottom isopen except for a spider 43 (see Fig. 8) which prevents the clothes" from getting sucked too far into the pounder with a piston shaped pound'er 41, which is omovable up and down in a 'cyllnder. 42,

cylinder. The spider 43 is provided with a central upward stem 'or rod 44'wh1ch steadies the cylinder by sliding in the tubu I lar lower part of'the pounder bar. v v

On each pounder'bar is secured a collar 45, above which is aspring 46 adaptedto act as a cushion up under the frame 37 and below said collar is amuch longer spring 47, theffunction of which is to yieldmgly re s e lind e2 ee en the clothes operated on.

The a n spasm with two apertures 48, through each of which extends from the piston 41 a light link rod 49, from the top of which extends a light contractible coil spring 50, having its upper end attached to an arm 51 of the frame 37. p 1

In order to make the frame 37 readily detachable from the shaft 15 its journal bearings on-said shaft are each formed of an upper rigid half bearing'or box 52 (see Figs. 3 and 6) and a lower half box 53. The latter is formed in the upper end of a heavy plate 54 having a recess 55 fitting the edges 56 of the frame when the portion 53 fits the underside of the shaft. In this position the member54 is held by a spring 57 (shown in Fig. 7) placed upon a rod 58, which extends from the member 54 through a slotted hole 59 in a post 60 onthe frame (see Figs. 6 and 7) and is provided with a washer 61 and pin 62 which hold the spring at all times partly compressed against the post 60. When the frame is to be removed the bearing member 54 is pulled outward against the'resistance of the spring 57 until it clears the frame, it is then lowered with its rod or stud 58 down intothe lower end of the slot 59, and is then turned at the stud ,to the position shown in dotted lines in Fig. 3 which allows the upper member 52 to be unhooked from theshaft, whereupon the frame 3738 and the pounders and their cylinders are all in one structure lifted out of'the main cylinder 10 so that clothes may be removed from and others placed into said cylinder.

The middle of the frame is offset downwardly and formed into an upper and a lower bar; the upper bar 63 (see Figs. 7, 9 and 10) bears up under the hub of the pinion 35 and has a rearward notch 64 fitting the front side of the shaft 12; the lower bar,

65, is formed with a notch or hearing 66 also fitting the front half of shaft 12, but upon this bar is pivoted at 67 a member 68 havin a notch 69 bearing against the rear side 0 shaft 12. The free end of this member or latch is provided with an embossment 70 within which is arranged a slidable looking pin 71, having a spring 72 tending to ho d it engaged in a cavity and 9) in the rigid bar 65. When the frame is to be removed from the machine this pin 71 is grasped by its head and raised and the bearing member 68 swings open for the vertical shaft to escape from the frame.

In the operation of the machine for drycleaning, the tub is filled about half full of gasolene, the clothes placed in the cylinder 10, the pounders are placed upon them, the gear 33 moved out of mesh with the pinion 35. The support 29 is thrown out of contact with the arm or lever 21. As the shaft 15 is then rotated the mutilated gears 36, 36 will engage the racks of the pounders and 73 (see Figs. 7'

' push them in alternate order down into the clothes in the gasolene,. and when each pounder cylinder 42 is sufliciently by the clothes to compress the sprlng 47 the latter yields and lets the piston 41 descend in the cylinder and expel air from it into the clothes until the gear has lost its engagement with the rack when the springs 50 will instantly raise the piston and-pounder to normal position, where it remains until the toothed part of the gear en ages the rack again and repeats the stroke. s the pounder ascends and the piston is' being drawn up ward by the springs 50 an agitating and cleansing suction takes place in the clothes until the pounder cylinder ets above the surface of the gasolene when 1t will instantly get filled with fresh air and thus ready for resisted the next downward plunge.- While this takes by the friction pulley 25.

When the clothes have thus been cleanedthe cover 8 is removed, the box or bearing

members

54 and 68 thrown open, the arm 21 raised upon the support 29, the frame 37 and the pounders removed from the machine, the gear 33 put in mesh with the pinion 35, the cock 7 opened and the shaft 15 rotated, the faster the better, so as to cause the centrifugal force to extract the gasolene from the clothes, whereupon the clothes are removed from the machine.

If the machine is to be used for common clothes washing the operationis the same as that already described for dry-cleaning,

sene may be used.

What I clalm is:

stationary cylindrical tub,'a skeleton tub r0 tatably mounted in the middle thereof and having a vertical shaft, a horizontal; drive shaft journaled across the top of the stationary tub and having operative connection with the shaft of the skeleton tub to rotate it, a frame detachably 'journaled on both of said shafts, 'two pounders arranged to work in the skeleton tub and having each a vertical rod slidable in the frame and at one side provided with a rack, two reversely arranged mutilated gears fixed shaft and arranged to engage and push downwardly said racks in alternate order, and springs arranged to raise the pounders whenever the toothed portions of the gears are turned away from the racks;

2. In a machine of the class described, a stationary tub, a suitable frame therein, arotary tub mounted centrally within the stationary tub outside'said frame, two poundwith the'exception that instead of ,gasolene' water and soap, and if so desired some keroon the drive ers arranged to operate in the rotary tub,

each of said drical hollow and a piston pounders comprising a cylinbody with an apertured top, movable in the cylinder and havinga pounder rod extending upwardly through the apertured top and mto the frame, a drive-shaft journaled across the stationary tub and in the frame and provided with means for driving the pounders alternately downward and there releasing them; two springs attached to each piston and to the frame and extendin through the apertures in the head of the cy inder part .of the ounder, to raise the piston and cylinder to t e upper position of each stroke.

3. ha machine of the class described, a vertical shaft and a horizontal drive shaft geared thereto, a frame detachably j ournaled on the two shafts, two ounders having each a rack-shaped rod sli ably guided in the frame. and the lower end provided with a giston', two mutilated gears fixed on the rive shaft and arranged to push the racks piston and having in its top two apertures, two pulling coil springs connected with the piston through said apertures and having short cushion coil spring on the rod close above the collar so as to contact with the' frame, and stop the upward stroke of the entire ounder with the least possible noise.

4. T e structure specified in claim 3,'said cylindrical pounder members having each in its open bottom end a spider, and a vertical central rod fixed in the s ider and slidably inserted in the pistonrro the latter being for that purpose tubular at least as far as said spider rod enters into it. downward in alternate order, a downwardly opencylindrical member fittedabout each- In testimony whereof I aflix my si ature.
