A Patented cpt, 16, 193@ i s JAMES N. WHITE, DENVER, COLORADO CYLINDER LAUNDRY MACHINE appneati fied. December 2, 1929. serial No. 411,061.

This invention relates to cylinder laundry machines and particularly to that class thereof in which there is a revolubly mounted cylindrical clothescontainer enclosed by an out- 51 er cylindrical casing, a portion of which casing is stationary and another portion of which casing is rotatable.

An object of the invention is to provide in a machine of the class -described,'an improved structure for dumping clothes therefrom, and an improved structure for dumping the washing iiuid therefrom and likewise to provide for the accomplishment of both of said results by one and the same element in the structure.

A further object is to provide, in a ma chine of the class described, improved, simple and efficient means for dumping the clothes; improved, simple and eiiicient means 0! for dumping the Washing fluid, improved,

simpleand efficient means for supplying the uid to the interior of the machine, and a simple inexpensive and eiiicient machine for combining the above mentioned features.

l rlhe foregoing objects will appear more fully and other objects will appear from the following specification and claims as illustrat/ed in the accompanying drawing in which like characters of reference indicate corresponding 7parts throughout, and in which Figure l is a front elevation of a machine constructed in accordance with the present invention, portions thereof being broken away to disclose the interior and certainv details of construction.

Figure H is a section on line AA of Fig. lf, showing the rotatable section of the outer cylinder in normal position during the operation .of the machine for washing. .Y

Fig. l showing the rotatable section of the outer cylinder in position for dumping the washing fluid from the machine.

' Figure IV is a view also on line AAO Fig. l but showing the rotatable sectiony of the outer cylinder in position for dumping the clothes Jfromv the machine.

Figure V is a detail View of a modification of the bearing assembly including a modi- Figure Hl isa section also on line ALA o .modified bearingfluid-inlet assembly shown in Fig. V.

The machine will bedescribed as a washing machine but it will be understood that,

vwith appropriate modilications, not aecting the present invention and obvious to those skilled in the art, the same may be used as a drying machine or for dyeing clothes.

It will also be understoodthat many changes may be made in details of construction without departing from the spirit or substance of the invention and within the scope of the appended claims.

In suitable supports, as standards 1 bolted to the iioor as vat 2, l provide bearings 3 and hollow gudgeons 4 which may be formed integral with webs 5 suitably fastened as by bolts 6 to the ends 7 of the rotatable section 7 of the outer casing, said section 7 comprising a tub enclosing, and for holding iiuid to immerse the lower portion `of container 8' when section 7 is in position shown in Fig. lll.

A. cylindrical clothes container 8, suitably perforated as indicated at 9, is provided on its ends with gudgeons l0 revolubly mounted within the hollow gudgeons l whereby at each end of the machine, the gudgeons 10, carrying the clothes container 8, :treely revolvewithin the hollow gudgeons l which serve as bearings for the gudgeons'lO, and hollow gudgeons 4 likewise freely revolve within the bearings 3 and independently of the gudgeons A10, whereby the clothes container 8 may be rotated independently of the rotatable section 7 of the outer casing and likewise the rotatable section 7V of the outer casing may be rotated independently of the container 8.

The outer casing has, in addition to the l standards l., The section. 1 1. is, preferably approximately three-quarter cylindrical, the

front edge thereof being approximately at or a littlebelow the longitudinal axis of the casing and the rear edge thereof being a little within the section 11 and is preferably about semi-cylindrical, whereby the section 11 always overlaps sectionv 7, either partially or entirely, according to the position of section 7. The relative circumferential extent of sections 7 and 11 may be varied as' desired so long as the two together form a complete outer casing, the stationary section of which will catch and lead to the bottom of themachine any water splashing or otherwise escaping over the edge 7a of the rotatable sec# tion during either the washing or dumping operations. 4 i

In the upper portion of section 11, a longitudinal recess 14 is formed, through which extends a pipe 15, adapted to receive steam or washing fluid from any suitable source through and controlled by the valve 16 and to admit the same into the interior of the machine through perforations 17 and such steam or washing iuid will enter the container 8 through the perforations 9. l

It will be understood that while the steam or washing iiuid is being admitted to the container and thereafter during the washing operation section 7 will be at the bottom, thus cooperating with section 11v to form a complete outer cylinder as clearly shown at by aiixing to extension 4a of one of the gudgeons 4, a worm gear 23 which meshes with the worm pinion 24 operated by a inotor indicated at 25, suitably supported as by a bracket 26. The worm gear 23 may be turned in either direction and when turned 1n one direction it will rotate section 7 to the position shown in Fig. III, which will open the outer cylinder at the bottom and allow the washing fluid to flow out of the Inachlne and it will be noted that as section 7 rotates, any of the Huid that overflows the receding edge 7a of section 7 *willy stlll be within section 11 and will flow down and over the apron 13 into a trough 27. In

dumping the washing fluid from the inachme, the section 7 will be rotated to the position shown in Fig. III so as to completely emptyy the machine of the washing fluid. Thereafter the worm gear 23 will be operated in the opposite ldirect-ion, thus rotating section 7 back through the position shown in Fig. II to the Iposition shown in Fig. IV, whereupon the-container 8 will be rotated to the position shown in Fig. IV, so

that the cut-away portions 28 thereof, which cut-away portions are' normally covered by the sliding doors 29, will be at the bottom, whereby the clothes will drop through the cut-away portions 28 out of the container and into the trough 27 or into any suitable receptacle which may be placed beneath the casing. VIt will be obvious that rinse water may be run from top,to bottom through container 8 from pipe 15 when section 7 is not in the extreme of either of the dumping positions shown in Figs.- III and IV; that is to say, whenever section 7 does not cover the under side of pipe 15.

It will be understood that the section 11 is provided with sliding doors 30 of usual construction and that the loading of the machine will be accomplished with the container and section 7 in the position shown in Fig. II, but that with the container and section 7 in this position, the doors 29 and 30 will be opened so as to permit the loading of the container with clothes through the openings or doorways afforded by the opening of the doors 29 and 30.

In the drawing the doors 29 and 30'are shown as sliding doors. No details of construction are shown or described because the construction of the doors is no part of the present invention. The doors in'a fixed section of the casing may be of any standard construction'. The doors in the container are preferably sliding doors which permit rotation of the container with the doors open as well as closed.

Heretofore special drainage means have been provided in cylinder laundry-machines for emptying the same of the washing Huid. Such drainage means generally involve pipes and valves protruding from the casing and not only cause additional expense in or1g1- nal production and in the matter of care and repair incident to operation, vbut catch dirt and various articles and generally interfere with operations around the machine, as any projection from the machine will do. Moreover, the drainage of such a machine through a pipe is comparatively slow and generally results in leaving settlings which have to be rinsed out. All of these objections are overcome by the provision of the rotatable section of the casing in the present invention, which quickly and completely dumps the washing iiuid from the casing and does it so quickly and effectively that no'sett-lings are left to require subsequent rinsing. Moreover, the outer surface of the casing is left comparatively smooth and free from such projections as pipes, valves, etc.

The advantages resulting from the opening of the bottom of the casing, thus per- Amit-ting the` dumping of the ,clothes from the container by the simple expedient of inverting the container, Will be obvious to those familiar with the operation of'washemphasis. j

ing machines and need no explanation or The present invention, not only gives the ladvantages of quick and complete dumping of Washing fluid, as above described, and

" the advantages of the Adumping ofthe clothes out of the bottom o f the container entirely l by gravity andA by the simple expedient of accomplishedA in a machine'which is of the interior of the machine through a hole 32 provided through the bearings 3 and 31.

lin the foregoing specification, structural details have not been dwelt upon, but it is believed that the disclosure hereof in the drawing is suflicient in itself to enable anyone familiar with this class of structure to construct Y a machine in accordance With this invention,

but sucient description 'of the detail hasv been added in the specification to eliminate any possible diculty in this regard.

lt will be understood that the machine hereinabove described is particularly adapted toI I Washmg operations in which the clothes are successively Washed, rinsed, and blued Without removing them from the container 8. Such successive operations involve the use of several separate and distinct fluids, each one of which must be removed from or let out of 'the machine before the next one is injected.

The operation frequently requires as hi h as eight or ten successive uids, necessitating a corresponding number of eliminations of the Huids from the machine. With this in mind,

the advantages of the independent rotation of the revoluble section 7 for the purpose of uncovering the bottom of the machine for quick elimination of fluid therefrom Without regard to the cylinder 8 Will be apparent. At

each of these operations, the machine herein described saves not only that time which is ordinarily required to drain the machine through the usual pipe and valve structure, but also empties the machine of Huid, dirt, and sediment in a more effective manner, by reason of the quicknessl of the eliminating operation and the movement of the fluid-containing section 7 Whenever it is moved to dump contained fluid.

In the foregoing specification, reference is made to the use of this machine for drying purposesl and to modifications thereof for such purposes. As ,there stated, various modifications, obvious to those skilled in the art, may be made, but it Will also be obvious to those skilled in the art that the machine as above described may be used as a drier immediately following the emptying from the machine of the last fluid to be used. When the fluid is emptied, section 7 may be independently revolved to the position disclosed in Fig. lV, cylinder 8 remaining closed and being revolved or not, as may be desired. With section 7 in this position, air, Which may be heated or under pressure or both, maybe let into the machine from the under side and from any suitable source of supply, which may be positioned under the machine for this purpose. Such air` Will not only circulate around the cylinder 8, but will penetrate the same through the perforations 9, and such air Will escape at the top of the machine. The rotation of cylinder 8 during this drying operation Will facilitate the drying.

lt is therefore obvious that the machine described can be used Without substantial interruption .for th'e successive. Washing, rinsing, bluing, and drying of the clothes, each of these operations, and especially the successive performance thereof, being greatly facilitated and some of said operations being ren- SUD dered possible, by the structure Which makes possible and provides for the rotation of section 7 independently of cylinder 8, and to an extent sufficient in either direction to uncover the bottom of the machine and the bottom of cylinder 8.
