' AppIication filed June 7, 1909. Serial No. 500,659.

To all whom it may concern:

Be it known that I, CALVIN A. SHIVE, citizen of the United States, residing at Payson, in the county of Lincoln and State of Oklahoma, have invented certain new and useful Improvements in Gearing for Washing-Machines and the like, of which the following is a specification.

This invention relates to washing machines and my object is to produce a washing machine embodying a perforated drum and automatic means for cooperating with the operator in oscillating the drum. 7

A further object is to produce a drum composed of a body portion and two doors disposed at, diametrically opposite points, one of which is detachable so that when it is removed and the other door is open, access may be conveniently had to clean thetub or receptacle without removing the drum,

A still further object is to produce a machine of the character outlined which embodies the desirable features of simplicity, strength, durability and cheapness of construction.

With these general objects in view the in vention consists in certain novel and peculiar features of construction and organization as hereinafter appears; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which e 1 Figure 1, is a side elevation of a washing machine embodying my invention. Fig. 2, is a vertical section taken on the line II-II of Fig. 1; Fig. 3. is a section taken on the line III-J11 of Fig. 2, Fig. 4c, is a perspective view of a part of the drum. Fig. 5, is a side elevation of a modified construction of the machine.

In the said drawing, 1 indicates a tub or receptacle of substantially semicylindrical form mounted upon supporting legs 2 and provided with a drain hole 3 normally closed by a plug 4, the cover 4* being of arched form and hinged as at 4' to a cross bar 4 secured to and bridging one end of the tub or receptacle. Arranged within this tub or receptacle is a preferably cylindershaped drum consisting of a body 5 having perforations 6 in its periphery, and the latter. corrugated as at 7, though if the drum is made of wood as indicated, the corruga tions by preference will only be on the inside as shown in Fig. 3, most clearly, the

end portions of the drum being also corrugated by preference as shown at 8. 9 and 10 indicate segment-shaped doors which fit agamst opposite edges of the end-portions of the body so as to conjointly form therewith a complete cylinder, the peripheral or curved portions of doors 9 and 10 being perforated at 11 and 12 respectively, the end portions of said doors being likewise corrugated by preference, as'at 16. The door 9 is hinged at 17 to the body of the drum and is equipped with a pin 18 to be engaged by a hook 19 pivoted to the body. The door 1 is provided with hinge-hooks 20 for pivotal and detachable engagement with pins 21 projecting from brackets 22 secured to the body and at its free end is provided with a pin 23 to be engaged by a hook 24 pivotally carried by the body. When the hooks 2 1 are disengaged from pins 23, door 10 can be swung open and if desired, can be detached from hinge-pins 21 by an obvious manipulation of the door.

25 are spider brackets secured to the endportions of the body 5 and provided with outwardly-projecting cylindrical trunnions 26 which extend through bearing brackets 27 secured to'the side walls of the tub or receptacle, and secured upon the end of one of the trunnions is a small external-tooth gear-wheel 28 which fits within and meshes with an internal-tooth gear-wheel 29 journaled on a stub-shaft 30 secured rigidly to the tub or receptacle vertically above wheel 28, and secured rigidly to said wheel 29 is a handle or lever 31.

32 is a pin projecting outward from gearwheel 29 in line with handle 31 and pivoted on said pin is a link 33, a spring-cotter 34 extending through said pin to hold the link in position thereon.

35 1s a pair of retractile springs secured at their neighboring ends to opposite ends of link 33 and at their opposite ends to the outwardly projecting arms 37 of a pair of angle brackets 38, embracing the corners of the tub and secured rigidly to the same by screws 39.

The springs are of substantially equal strength and therefore normally hold the handle 31 projecting vertically upward and the drum with its door 9 uppermost. With the parts arranged as described the door 9 can be easily opened and the articles 40 to be washed dropped into the drum. Boiling swinging the handle water, containing a suitable washing comerator then grasps the handle and rocks the same in an obvious manner, preferably far enough toward each side to move the contents'of the drum approximately to the position shown in dotted lines, Fig: 3, it beii g understood that when the handle is swung toward one side it tensions the retractile spring at the correspondingside'and permits theother spring to relax, the oscillation of the drum, of course, being effected through the turning of the small" gear-wheel by the large one secured to the handle. A. comparatively slow movement of the handle imparts rapid movement to the drum, so that the articles therein shall acquire suflicient momentum by the time they are raised to the-position shown in dot ted lines, Fig. 3, to be proj ected'in the direction indicated by the arrow, same figure,-to

the opposite side of the drum. The articles will impinge upon'such side with sufficient force to continue therotation of the drum for a slight distance without further effort on thepa-rt of the operator,- this continued rotation continuing the movement of the handlein the same direction and increasing the tension of the tensioned-spring, which spring immediately retracts'so" as to start 7 the reverse oscillation of the drum and handle, this reverse operation being assisted by the operators pressure or pull on the handle. YVhen. the drum'has been rotated in said reverse direction the proper distance, incidentally tensioning the originally relaxed sprin and permitting the originally tensione spring to relax, the articles through the momentum acquired jump to the opposite side of the drum and thus increase the extent of such reverse operation and the tension of the spring-originally relaxed, all subsequent operations being repetitions of those described. From the foregoing itwill be apparent that the actual'labor entailed on theoperator is small, asthe articles'being washed are utilized by inereasing'the' tension of the springs alternately, to" cause said springs to react strongly and thus perform the actual reversing operation of' the drum, and leave the operator the duty only of continuing such operation for a suitable distance in each direction. V

r If desired tovclean the tub or receptacle after the Washed articles are removed and the water has been drained from the tub, the handle 31 is turned" until the door 10 is uppermost to permit such door to be detached from the drum. -The handleis then released and the tensioned spring retracts and revolves the drum back to its original position with the door 9 uppermost, which mally exposed screws 38- disposed by Fig; 1 the.

door, is then opened and the'operator given access to the bottom of the tub or receptacle I through the drum. p

For convenience in. removing the drum from the receptacle, the arms of the spiderbrackets 25 are'of such length as to project above the tub or receptacle as shownclearly. in Figs. 1' and 2, so that the screws fastening said spiders to are conveniently accessible. After the northe body of the drum are removed, the V handle is manipulated to turn the drum one- 7 half revolutionso as to exposethe other two" screws, as willbe readily understood By reversing these operations the drum can be resecuredinthe tub.- I In the preferred'construction disclosedib'y Fig. 5, the springs 35 arearranged' at diametrically opposite sides of" gear wheel 29 and attheir inner ends areattached to links 33* pivoted to said wheel at po n diametrically opposite from eachother and equal distances f'rozn'the handle 31, of the springs beingattached to thebrackets in the horizontal plane of" the axis of said'jwheel. When the handle-21 is operated both springs 35 "ofi'er a yielding resistance and when the springs cohperate in returning andhence the drum to normal position. By this construction it ispractical'to employ springs of" approximately half the strength of the springs employed in the construction shown by Fig. 1 asin the last-named? con stru'ction, the springs'alternately offergyield ing. resistance to the operation of the-handle the outer ends 7 handle is released said 7 the handle and do not co'ciperate in returning-thehandle V to normalposition, t 7

Referring now tofFig; 5, it will beseen that thefsprings 35* are arrangedin the hori-r zontal plane of'the axis oflwheel' 29' and are q f pivotally connected at their .inn'er'endsto said wheel and proj ectingj arms '37 of brackets 38-,"which in this figure are; disposed in a higher plane than in Fig, 1. This arrangement'of parts permits the use of lighten'or weaker springs, as the:springscohperate in resisting movement of the handle awayfro'm avertical positionand in'returningthe handle to such tion shown by Fig. f where each spring re- 7 sists movement of the 'handle away from the vertical and then" assists in drawingfit back to such" vertical position; With the tains' an impetuswhich assists the operator atdiametricallyfopposite p i t V at. their outer :endsto the outwardl '1'10' position asdistinguished from the construe in overcomingthe resistance of the springs without exertion. In the construction shown p osed'sudd'enly at'times to make the operaresistance of thespringsi's im- V 7 From the above description it will be apparent that I have produced a washing machine embodying the features of advantage enumerated as desirable and which is susceptible of modification in some particulars without departing from the principle of construction involved. 7

Having thus described the invention what I claim as new and desire to secure by Let ters Patent, is z- A gearing for washing machines and the like, comprising a suitable support, a ro tatable object journaled on said support connected axially thereto a gear, an internally-toothed gear wheel disposed eccentrically of and inclosing and meshing'with Copies of this patent may be obtained for five cents each, by addressing the said gear, a handle secured to and projecting from said gear wheel whereby to oscillate the same, a link pivoted on said gear wheel at a point in line with said handle, and a pair of retractile springs connected at their opposite ends to said link and said support respectively and adapted to maintain said wheel with its handle normally in vertical position.

In testimony whereof I aflix my signature, in the presence of two witnesses.
