Specification of Letters Patent.

Patented Apr. 45, 1915.

Application filed June 21, 1912. Serial No. 704,976.

To all 'zc/mm it may concern Be it known that 1, Jason Lns'rnnnnnonn, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Washing-Ma chines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in washing machines of that class in which the rubber shaft is rotated in alternate directions and longitudinally moved at the same time.

The objects of my improvements are to provide a simple, substantial and; durable machine of this class, which shall be highly efficient, and extremely cheap I in cost of manufacture, and in which frictional resistance to the movement of the moving parts has been re need to the ineiniinum.

attain these obje ts by the mechanism illustrated in the hccompanying drawing, in which j Figure 1,is a side elevation of the machine, certain parts being in section, to avoid obscurity; the movingparts being shown at the lowest point of their movement. Fig. 2 showing the parts at a higher point of their inovement. Fig. 3 is an enlarged, transverse section of the moving parts, on the line X X, seen in Fig. 1. Fig.

d ise horizontal section on the line Y Y,

seen in Fi Fi 5 is an enlar ed ed e. D b

view, in detail, of one of the toggle bars. Fig. 6 is a side elevation of one of the other various forms in which the machine may be constructed.

Referring to Fig. 1, tub 1 may be formed as shown, or may be of any other form, suitable to hold suds, not shown. The interior surface of said tub, may be either smooth or corrugated, as desired. Said tub is provided with bottom 2 and cover The latter has a large square opening 3 formed there through. Said opening is closed by lid 4-, hinged at one of its edges, on said cover by hinges l, and has its free edge detachably secured to said cover by turn buttons l, seen in Fig. 2. Frame 5 has frame base 5 formed therewith, said base being rigidly secured. on lid 4. Said base. the upper portion of said frame and said lid, each have an aperture formed through the central portion thereof. Vertical rubber shaft 6 is passed through said apertures, and is rotatably and slidably mounted therein, as here inafter described. Said shaft has notches 6 formed in one of its edges. Referring to Figs. 3 and 4, said shaft is preferably formed of an X shaped metal bar and has cross head '7 clamped thereon by clamp 8. Said clamp has clamp projections 8 formed on its inner surface, which engage notches 6 for adjustably holding shaft 6, at any desired height. One of the ends of said clamp is detaohably secured to cross head 7 by clamp hook 8' formed with said clamp and passedthrough an aperture in said cross head, while the other end of said clamp is secured to'said Cross head by thumb screw 9,

passed looselv through said clamp and screwed into cross head 7.

Referring to Fig. 3, sleeve 7 is formed with cross head 7 and extends therefrc iin, loosely through the previously mentioned apertures in base 5 and lid 4:, for slidably and rotatably guiding the lower end portion of shaft 6. The upper end of said shaft passes through and is slidably guided by journal piece 10, rotatably mounted in the previously mentioned aperture through the upper portion of frame 5. Said journal piece is held in place by the upper end of spiral spring 11, the lower end of which presses upon and is supported by cross head 7. Referring to Fig. 4c, each of the two ends 'of said cross head has a ball 7 formed therewith, and provided with ball jointed supporting means therefor, since they are both alike in construction and operation, a detailed description of one is sufficie t.

Referring to Fig. 5, toggle bar 12 is formed of separable halves secured together by bolts and nuts 12. Said bar has a socket 12 formed in each end thereof. Said sockets are adapted to interchangeably fit on ball 7 and bearing ball 13, the latter being provided with stem 13 formed there with. Said stem is secured in frame 5 as seen in 1. Cross arm ball 7 is held in one of said sockets, while the other socket embraces bearing ball 13, thus providing ball jointed supporting means for cross arm 7 as previously mentioned. Drive block 14 has rose face 14 formed on one side thereof. Said block is secured on the X shaped reduced portion 6 of shaft 6, by nut 15 screwed on the farther reduced and threaded portion 6 of shaft 6. Crank 16 has rose face 16 formed on the inner end portion thereof and spherically shaped handle 16 I 4, after which said lid 18 as indicated by dotted lines.

mounted on the outer end of said crank. Rose face 16 is secured in engagement with rose face 11, by thumb screw 17 passed loosely through said crank at the center of said rose face 16 and screwed into drive block 14 at the center of face 14, for adjustably securing said crank on said block with handle 16 at any desired height. On the lower end of shaft 6, is secured the rubber disk 18, having apertures 18 formed therethrough. Rubbers 19 are secured on the lower surface of said. disk, and may .be either four in number, as shown, or may be of any other plurality in number, arranged radially on the lower surface of said disk.

In preparing the machine for operation, (the parts being in position seen in Fig. 2,) thumb buttons a" are rotated from over lid is rotated on hinges 4: from cover Suds and fabric, not shown, are passed through opening 3 into tub 1 after which the parts are returned to the position shown in Fig. 2. The operator with one hand graspshandle 1 6 and moves it to a point near point B, then with the other hand he loosens thumb screw 9 and draws the thus loosened end of clamp 8 from shaft 6,- until clamp projections 8 are disengaged from notches 6, 'upon which said shaft and the thereto attached-parts gravitate until rubbers 19 rest upon said fabric. Said-operator returns cap8 to its position shown, with projection 8 in notches 6 and tightens thumb screw 9, after which the machine isready for'operation. Should handle 16" be at such height as is uncomfortable for said operation, the same is adjusted .to

proper height by loosening thumb screw 17 forcing said handle to the desired height and tightening said screw. In operation said operator reciprocatively moves handle 16 between points A and C, seen in Fig. 2. When said handle passes point B the parts are at their lowest point of movement, as seen in Fig. 1, at which point rubbers 19 and y pressed upon said I fabric. At the same uncture, said suds escapes from said fabric, through apertures handle is moved from point B, in either direction, the lower ends of toggle bars 12 are moved from the position seen inFig. 1 to a higher position seen in Fig. 2, and describe a spiral, upwardly inclined are. This move,- ment of said toggle bars 12, carries cross head 7 and its attached parts, to said higher position. Said upward movement of said parts could be As said part continues so long as handle'16 is moved from point B, in either direction, until the limit of said movement is reached.

The upward movement of said cross head compresses spring 11 which elastically formed, said suds is drawn from tub I,

through plugged aperture 20, in the u's ual mannen While I have shown and described my invention in the foregoing manner, with toggle bars 12- depending from bearing balls 13,

and with spring 11 and journal piece 10.

above said cross'head it is evident that said placed in transposed position, as seen in Fig. 6, with sleeve 7"shortened as seen at 7 and journal piece 10 secured in frame 5 by set screw 10''.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent is z' The combination with a tub provided'with I a lid thereon, of a frame securely mounted on said lid; an agitator shaft having its upper end portion rotatably and slidably mounted in the upper portion of said frame the lower end portion .of said shaft being extended throu h said lid into said tub; an agitatorsecured on the lower end of said shaft; a cross-head -'adjustably secured on said shaft above said lid; a guide sleeve formed with said cross-head said sleeve passing loosely through said lid-and encircling said shaft to laterally guide the lower end portion of said shaft means whereby said shaft is rotated in alternate directions; and

' link connecting means whereby the ends of said cross-head are connected with said frame for raising and lowering said shaft when the same is rotated.

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