GEARING FOR WASHING-MACHINES.

Application illed October 9, 1917.

To all inkom 'it may concern Be it `known that I 'JAMES L. Corman, a citizen of the United `tates, residing at Dayton in the county of Montgomery and State of hio, have invented certain new and useful Improvements in Gearing for Washing- Machines, ofwhich the following is a specilisation.

Thisinvention' relates to a new and useful form and arrangement of driving gear for Washing machines, and to the washing cylinder i clothes receptacle. The object of the injtion is to provide a gearing which is Simp ed and compnet in its arrangement, it beingessential to concentrate the gearing as eompactly as possible to enhance the appearaneeof the machine as well to simplify details.` In carrying ont this object and purpose one of the side frames is especially constructed with a view to locating the reduction gear on the' inside of the frame and closely adjacent thereto while the power transmission Shaft and the gears therewith associated are located on the outside of the frame closely adjacent thereto. This ar- -rang ent of the driving gear avoids any cumbersome aspects and enhances the ap- Eearanee of the washing machine a whole y avoiding any unsymmetrical protuberanees or outlying elements and thereby ren- Aders the machine satisfactory, both as to The mounting of elliciency and appearance. the driving mechanism wholly on one of the side frames has decided advantages. This side frame holds all the working parts in true alinement, and the wear is therefore reduced to a minimum and eflicieney is greatly enhanced. The operating mechanism constructed and arranged in this way is easily assembled as a unit on one side frame. This facilitatesthe machining and assemblin in the manufacture of the.. ma-

rovides for an easy handling and the replacement of parts in case of wear `beingcomp aratively easy owing to the entire driving gea,` being located on one side frame as before stated. v

Preeeding a detailed description of the invention, reference in general terms is made to `the aeeompan ing drawings,of` which Figurel is a si e elevationA of a Washing machine equipped and construe d in accord-l ance with the improvements em odied in my invention.

what enlarged section of a portion of the side frame and the driving gear mounted thereon, including the reduction gear which lies on the inner side of the frame and the power transmission gear which lies on the outer side of said frame, both being closely adjacent to the frame. Fig. 4 is a cross sectional view of the washing cylinder which is driven through means of said gearing, and Fig. 5 is an elevation of the end of said washing cylinder with which the driving gear is connected.

In a more articular description of the invention similar reference characters are employed to designate corresponding parts both in the description and the drawings.

The supportingmfranie of the machine is of an open work character consisting of

side frame members

1 and 2 which are united by suitable

cross frame members

3, 4 and 5, the whole being designed to be light and rigid as well as symmetrical in appearance. The clothes receptacle consists of a cylinder 6, the journals 7 of which have bearings in corresponding portions of the

side frame members

1 and 2, the ends of said cylinder having attached thereto spiders or frames S from which the journals 7 project in reaching their bearings. The interior of the cylirlder 6 is provided with a longitudinal rib 19 1which forms an obstruction or barrier, the effect of which is to throw the clothes (from one side to the other into the suds al the cylinder 6 is oscillated. This rib or obruetion 9 is essential] of a rounded forni and devoid of sha edges in order to avoid injuring the clot es during the operation id. to avoid tying or knottin the clothes y they are moved over the pro] ection. The rib 9 being of the form or contour shdwn in the drawings has the effect of throiw` g the clothes into the suds from one sid to the other in a more open or separatediccmdition which is highly desirable both for the reason that the clothes are revented from bein torn or injured during the operation o washing and are maintained in a more open condition. There are also provided on the interiorof the cylinder 6 a series of longitudinal ribs 10 of Substantially smaller form, but of rounded.form` also, these ribs being designed to istrengthen or brace the cylinder. AQ door r1.1'fispl'ovided at the top of the cylinder 6j witha Suitable handle ,12 b which it `is removed andreplaed. The si e freine member 2 is more especially constructed with y The gear 29 is fixed to the shaft a view to supporting the driving mechanism which is compactly distributed ou both Aaldea thereof, The' motor 13 is located on the inner side of the frame member 2 by means of a suitable bracket 14 which is in turn supported on the

cross frame members

4 and 5. The .shaft of the mot-or carries a pulley 15 which drives :i belt 1G through which power is transniitted to a larger pulley 17, the .journal 18 ot' which is provided with a bearing' located also on the inner side of the frame member 2 in a. skeleton housing 1.9 which is a part of the side frame const ruction. An angular lever 2O is fulerumed at 21 on the inner side. of the frame member 3 which carries a beltV tightener 22 on one arm engaging thc belt vlt and a spring is cow nected to the other arm ot' Said lever. the tension of which maintains the tightener 22 against the belt 16 with sutlicient pressure to drive the pulley 1T. Any momentary relaxatiou of the belt tightener interrupts the transmission ot.' the power from thtl motor. The journal or stud Shaft 18 ofthe pulley 1i' carries a small gear or pinion 2l which meshes with a larger gear 25, both fears 'Lt-l and 25 being positioned on the interior of the offset or skeleton frame 19 or within the confines of the side frame 2. The stud shaft 26 of the gear is journaled in a bearing.; 27 which extends from the skeleton frame l!) and carries a bevel gear 28, through which an upright transmission .shaft- 30 is driven, there being a similar gear 2t) on the lower end of said shaft 30 which in mesh with the gear at E28. The shaft 30, it will be oh served, lies relatively close to the side frame 2 and on the outer side thereof. being su pported in a bearing 31 on the skeleton frame 19 at its lower end and in a bearing 3Q projecting from the side frame 2 at its upper end. The said shaft 30 carries at its upper end a bevel gear 33 having an extension 3l which lies in the bearing 32 and is provided on its upper end with a clutch member 35. StL but gear 33 is loose upon said Shaft 50. The shaft 30 extends upwardlyr and a clutch member 36 which cooperates with the clutch member 35 is mounted on said shaft 30.` The clutch member 3G has slidable movement on the said shaft 30, but rotates therewith by being splined thereto. The clutch member 86 is operated by a clutch shifter consistingr of a yoke 37 which spans the body of the clutch member 36 and is provided with pins 38 which enter a peripheral groove 3!) in the body of the clutch member 36. The voke 37 is pivoted to the side frame at 4t) and eX- tended therefrom is annperating lever 41 through whic'i the shiftable clutch member 36 1s operated.to release or engage the clutch member 35. lVhen the clutch member 35 is thus engaged the gear 33 is caused to rotate with the shaft 30 and to drive the washing cylinder t5. When the clutch membersl are released as in Fig. 3, the operatirm of the washing cylinder ceases. The. gear 33 meshes With a similar bevel gear 4:2 on a short or stud Shaft 43 which journaled in a bearing provided in an 'adjacent' part of the side frame 2. The connect ion between the shaft. 43 and the washing cylinder 6 consie-ts of a crank 44 one end of which is fixed to the shaft 4.3, and a connect ing rod t5 one end of Vwhich is pi voted to the crank l1 and the other end of which is connected by a pivot 1lb to a portion of the spider 8 on one cud of the washing cylinder. it will be seen that as the gear 42 rotates an oscillatory movement. is imparted to the cylinder which causes the clotliea therein to be thrown back and forth fron.- ;nie side to the other of the cylinder. 1What may be termed a shack absorber is provided for the shaft 4'? to pre vent sudden jerks being imparted to the cylinder or au irregular movement, This device consistsl of projeetioi'is 47 extending from the base of the grr-ar L112 or fixed to the khatt lf3 on the ont-sid(- of the frame 1?.. 'Fliese projet-tions li" are in [he forni of wipers, which engage during the rotation ot' the gear, the concavutl surface 48 of an arm 49. The .firm 49 is pivoted to the outside of the frame 2 at .30 and the outer end of .said arm has an openingr therein which receives a rod 51 which is Asecured to the frame 2 between lugs 52. Arranged between the lugs 52 are upper and lower coil springs which provide cushions or a means of yielding resistance to the arm 19 as the gear 42 rotates and the wipers or projections 47 engage the concaved surface 4S of said arm. The ma chine in its entirety i5 supported upon suitable casters 54. The several gears together with the clutch which are on the outer side ofthe frame Q a re suitably incloscfl by caps which may be conveniently united to the side frame These caps have been omit-ted from the drawings `in order that the gearing may not be obscured, but it will be understood that. the gearing as .shown in Fig. 1. is all concealed within these inclosing caps and the appearance of the machine is greatly enhanced thereby, there being no visible moving part. appearingr on the outside of the machine. `I have, in` connection with my improved washing machine gearing. Shown an electric motor 13 as the power furnishing element. lt will, however, be understood that other forms of power generators may be employed Without departingr from the essential features of my invention as set; forth in the precedingr part of this .specificat-ion. The upright shaft 30 is extended up beyond the washing machine proper Vin order to utilize the same to drive the rollers of a wringer. The wringer is no part of the l present invention and needv be referred to briefly as consisting of a frame 55 having llt? the usual wringer rolle'r's' V56 and 5T, the latter roller beingrdriven from the shaft 30 through a'r common A,form of gearing which is inclosed in a gearbox 58 and from which a shaft 59 is driven, the latter shaft being suitably connectedwith the wringen roller 57. 'The wsinger is mounted upon a swing ing support l(i0 which maybe swung over and to one side of the washing machine as is usual in the case of swinging wringer snpports.
