Application May 31, 1935.

24 Claims.

lhis invention relates to the art of washing machines particularly of the type a apted to he used in commercial dry cleaning ano undry establishments, and this application is a continuation in part of my prior application for U. S. Letters Patent filed November 22, 1929, Ser. No. 109,108. l

important objects of my invention reside in providing structure wherein the outer hull may he revolved to the elevation of the door opening thereinfroin the floor; wherein an unloading platform maybe readily inserted from either of two doors in the inner cylinder; and wherein a safety blast relief is automatically provided prior to opening of a door, in th hull.

' Other objects reside in the various unique coinbinations of elements permitting a simplified structure capable of being produced at a relatively low cost and of being operated with the minimum expenditure of effort upon the part of the operator. These and additional objects will be apparent in the following description of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a top plan view of a machine can bodying my invention;

Fig. 2, a front elevation;

Fig. 3, a right hand end elevation;

Fig. l, a left hand end elevation;

Fig. 5, a detail of the hull shifting mechanism in right hand elevation; v

Fig. 6, a fragmentary vertical transverse section through the hull, with the doors open;

Fig. l a vertical transverse section through the cylinder only with the doors closed;

Fig. 8', a horizontal longitudinal section through the cylinder on the line 8-8 in Fig. 7

Fig. 9, a fragmentary front elevation of a modi [10 fled form. of fluid intake piping; and J2 ture shown in Fig. 9.

Like characters of reference indicate like parts throughout the several views in the drawings.

l form the two symmetrical supporting standards l5 and 16 to have essentially an inclined A built up from structural channel iron, each having a vertical rear leg 17, an inclined front leg 18 welded to the rear leg at the top, a'hori- 7 zontal lower tie 19, and the central brace 29, extending at right angles from the front leg 18 downwardly to abut the rear leg 17. The front leg 18 is preferably sloped toward and united with the rear leg 17 at an angleof thirty degrees, whereby only sixty and ninety degree cuts are required on the ends of the tie 19 and 29. Longitudinal members 21 and 22 tie the standards together near their lower ends.

On the outer faces of the front legs" 18 of the standards are fixed the bearing plates 23 and 24 6 directly over the braces20, which bearings ro- Fig. re, a left hand side elevation of the struc- Serial No. 253,

y on, 1 provide bands of strap iron, 28 23, on atveach end, to pass circumferentially round to have their rear ends secured to the member 22 and their front endsv to the upper ends of links 30 which are pivotally secured to the inenloer 21, Figs. 3 and l, and. a shaft 31, ly supported between the front legs 13, hit; earns 32 adjacent the links 30 and a forwardly extending arm 33, whereby downward pressure on the arm 33 will rock the cams 32 against the links 30 to swing them, rearwardly and hence pull downwardly on the hands 28 and 7 29 to tighten them against the hull 2'7.

Cleaning fluid is supplied to the hull 27 through a fitting 3% ed on the back of the standard 15 from which a length of flexible hose 35 extends to an L 36 which screw-threadedly fits into the wall of the hull 27. The fluid may be drained from the hull 2? through the L 37 in the bottom of the hull 2?, through the flexible hose 38, the fitting 39 fixed to the tie 19, the valve 40, and out the pipe l1. To prevent overflow of the g5 hull, a hy-pass is provided around the valve 40, Fig. 4, in the form of the vertical pipes 43 and 4 1- with the horizontal connection 45 thereetween. By providing the flexible hose 35 and 38, the hull 2'7 may he rocked through an appre- 9o ciaole circumferential travel before being limited bythe hose l ngths.

A cylinder 46 is carried within thehull 2'7 and has shafts 47, and 48 extending longitudinally through the hull trunnions25 and 26 to be i'ockably carria in the bearings 49 and 50 mounted on the legs 18 of the standards 15. and'lii whereby the cylinder may be revolved within the hull "rdependentiy of rotation of the hull. ,The

48 extends beyond the bearing 50 and has a sour gear 51 fixed thereon, which gear meshes idler gear 52. A drive gear 53 meshes with the idler gear 52 and is fixed on the end of the shaft Mcarrying the driving pulleys 55.

A housing 56 is provided to enclose the gearing. A crank shaft 5"! is rotatably supported on the standard 16 to he iixed'longitudinally thereover.

On the inner end of the shaft 57 is a gear 58 in constant mesh with a rack gear 59 fixed on the end of the hull 22 On the outer end of the shaft 5'2, is carried a hub 61 with a gear 62 on the inner end and a crank 63 on the outer end.

An annular slot 6% is forined in the hub outside of the gear 62 and a pin 65 normally extendsfto wi n the slot to prevent longitudinal movement of the hub 61 along the shaft 57. In that position the gear 62 is out of mesh with the 51. he outer end of the shaft 5'] has a pin 66 or. Log diametrically therethrough, the ends of which are engaged in slots across the 20 outer end of the hub 61. Thus, upon rotation of the crank 63, with the pin 65 entered in the slot 64, the shaft 5'! is revolved through the pin 66 to revolve the gear 58, which in turn causes the hull 27 to revolve, upon release of the bands 28 and 29.

Upon pulling the pin 65 out of the slot 64, the hub 61 may be shifted inwardly along the shaft 5'7 to mesh the gear 62 with the gear 51, whereupon, revolving the crank 63, will revolve the cylinder 46 within the hull, without moving the hull. A plate 67, fixed on the outer end of the shaft 18 has a double ended arrow 58 painted thereon to indicate the positions of the doors 69 and '70 in the cylinder, so that, upon registering either head of that arrow 68 with the fixed point '71 on the housing 56, either door in the cylinder will be properly presented for unloading the cylinder as will hereinafter be explained.

The hull 27 is entirely closed save for an opening '72 for a length circumferentially therearound, the normal position of which opening is on the upper side of the hull. Arms '73 and '74 are hinged respectively to the upper ends of the standards 15 and 16 and carry between their outer free ends the transverse bar '75, with the brace bar '76 tlierebehind. A door '77 is hingedly supported by the bar '75 by the straps '78 and '7 9 extending from under the outer ends of the door and wrapping around, over and downwardly about the bar.

A center strap is provided to support the center of the door. The door '77 carries a front door 81 hinged thereto along its front edge, the combined doors being sufiicient to cover the opening '72 into the hull 27. Along the under side of the front edge of the front door is a lip 82 which enters under the edge of the opening into the hull and prevents the upward swing of the door 81. The rear door '77 may be lifted freely from over the opening 72.

Wooden cam blocks 83 and 85 are fixed to the ends of the hull 2'7 to project beyond the circumference thereof and are positioned relative to the opening '72 into the hull 27 whereby rotation of the hull will immediately enter theblocks under the rear upturned ends of the straps '78 and '79 to lift the back edge of the door '77 thereby venting the hull before the front door 81 may be opened by reason of the restricting lip 82. Continued rotation of the hull 2'7, by the crank 63 as above described, will carry the hull around to bring the forward edge of the opening '72 out from over the lip 82 and from under the door 81 whereby the door 81 may then be lifted and swung around upwardly and rearwardly to permit access to within the hull. The blocks 83 and 85 have, upon such rotation, moved around until the door '77 is entirely lifted and spaced upwardly from the surface of the hull, thereby preventing the possible production of sparks from rubbing metal over metal, the blocks being preferably made of wood. The lower edge of the opening '72 is brought around and down to a convenient height over which an operator may work in loading and unloading the cylinder 46.

The cylinder 46 is revolved by the crank 63, as above described, to bring either one of the two doors 69 or '70, here shown as 70, around and under the opening '72 so that the door '70 may be opened outwardly and upwardly therethrough, Fig. 6, to permit access to within the cylinder 46. In order that an operator will not have to put his head into the cylinder to unload it, I provide an unloading platform 86, here shown as built up from slats. On each side of the platform are two projecting fingers 8'7 and 88 respectively, Figs. '7 and 8. The platform 86 is inserted through the opening of the door '70 in the cylinder as and the fingers 8'7 on the far side are engaged in notches provided therefor along the edge of the door 69 and under the rib 89. The

near edge of the platform is then just above the rib 90 and the fingers 88 extend outwardly therefrom to be received in notches in the lower edge of the door '70, which may then be closed. The cylinder is revolved 180 degrees to bring the door 69 around to the hull opening '72, which action has brought the clothing (not shown) previously under the platform around and on the then top appearing side so that the clothing may readily be reached and pulled over the platform and out the opening '72. Obviously the hull and cylinder may be stopped to provide any angle of slope desired to the platform. Upon unloading, the platform may be removed from the door 69 at once without further rotation of the cylinder.

Referring now to Figs. 9 and 10, in place of employing the intake fitting 34 and the hose 35, fluid may be introduced to spray down over the cylinder 46 to enter the holes 91 therein, by introducing the fluid through a fitting 92 centrally carried between the standards 15 and 16, a length of flexible hose 93, a Y-fitting 94 and the laterals 95 and 96 to the distributing pipe 97 which is substituted for the bar '75 between the arms '73 and '74. Nozzles 98 project from the under side of the pipe 9'7 through the door '77. Thus, the pipe 97 is raised and lowered with the door 77 by the blocks 83 and 85.

In dry cleaning establishments where volatile grease dissolving fluids are employed, it is a frequent occurrence to have explosions within the hull and many operators have been injured thereby. With my construction, the rear door '77 is always free to be lifted upon an interior explosion, and the blast therefrom is directed rearwardly away from the operator who may be in front of the machine. Furthermore, as above indicated, the front door may not be opened until after the rear has been opened to vent the hull. Chemicals are frequently added to the fluid within the hull while the cylinder is being revolved. As a precaution against injury to the hull 2'7 through which wrenches may be inserted to tighten bolts 103 through the flanges 102 supporting the cylinder 46.

While I have here shown and described my invention in the one best form as now known to me, it is obvious that structural changes may be made therefrom without departing from the spirit of the invention, and I, therefore, do not desire to be limited to that form nor any more than may be required by the following claims.
