Fig. 8 is an enlarged vertical cross-sectional view taken along the line 8-8 of Fig. 3 but with the closure member in its open position.

Referring now to the drawings and more particularly to Figs. l to 5, inclusive, it may be seen that the ash tray of the present invention includes a base I0 and a removable cover I2. The tray is characterized by the large ash receiving space I4 in the base or receptacle, as it may be called, and the ready removability of the cover from the base. The base preferably includes a circular bottom I6 and an annular side wall I8 terminating in a flat top surface 20. The base is preferably of integral construction and may be made as by die casting. The cover I2 includes a central raised or vupstanding easily gripped portion 22 and a thin outer peripheral portion 23, whereby the cover may be easily removed and which necessitates positive and secure gripping of the base when the ash tray as a whole is to be moved.

The cover is provided with a plurality of radial cigarette receiving grooves 24 and the cover constitutes structure defining a receptacle opening 26. The opening 26 is formed centrally by a downwardly and inwardly inclined wall 28, the lower edge of which and, therefore theV opening, are in a substantially horizontal plane.

In accordance with one of the important features of the present invention, the opening 26 is adapted to be normally closed by a closure member indicated, as a whole, by reference character 30. In order to facilitate construction and improve operation, the outer surface 32 of the closure member is curved, and preferably generally spherical thereby substantially completely to close the opening 26 when it is in its closed position. The closure member is so mounted relative to the opening, as will be described in detail hereinafter, that in closed position it vapproaches substantially closely to the lower edge of wall 28 and closes the opening 26, whereas as soon as it is moved toward and when in open position, it is spaced from the wall, thereby enabling the closure member readily to bevmoved.

In accordance with a further feature of the present invention, the closure member is provided with a, depressed central cigarette butt receiving and snufiing groove 34 of substantial height and preferably tapered so that the butt m'ust .be forcibly pushed therein and when so pushed isextinguished and held. Y

A cigarette, or a plurality of cigarettes in the snuffing groove, is ejected into the receptacle space I4 when the closure member is moved to its open position. This ejection is accompli-shed by an ejector tongue or linger 36 extending downwardly and inwardly into'the groove 313, which grooveextends in the direction of movement of the closure member or, otherwise stated, length- Wise relative to the direction of movement of the closure member. The tongueforms, in effect, a continuation of the side wall 23. The opposite end of the groove is normally closed by a similar tongue or finger 36. f

`The closure member 3G is mounted or pivotal or oscillatory movement about an axisdeiined by shaft 40 located below and substantially centrally of the opening. The shaft is supported in a, pair of spaced apart downwardly extending

lugs

42 and 44 formed integral with the cover and located at opposite sides of the opening 26. The closure member is rotatably supported upon the shaft 40 by a pair of spaced apart and apertured

side walls

46 and 48 through which the shaft extends. In order to provide additional freedom for movement of the closure member, brass washers 50 are interposed between the

side walls

46 and 48 of the'closure member and the

dependent lugs

42 and 44 of the cover. The brass washers reduce the friction and properly position the closure member and cover relative to each other. The cover and the closure member, it should perhaps be mentioned, are made of the same material and in the same manner as the base.

The closure member is operated from its normally closed to its receptacle opening position by a novel operating mechanism including simply an actuating lever 52 having a generally vertical portion 54 extending above the cover through an opening 55 in the upraised portion 22 and having an inwardly curved lower portion 56 pivotally connected directly to the closure member. The opening 55 is aligned with groove 34 and is located substantially midway between the

lugs

42 and 44. The pivotal connection includes a pin 58 parallel to shaft 4U and passing through the curved lower portion of the lever and through a pair of spaced apart lugs 60 (only one of which is shown in Fig. 4) formed integral with central spaced apart webs 62 extending below the central portion of the closure member, the arrangement thus constituting a, single xed pivot connection.

The actuating lever 52 is depressed to open the closure member but the direct pivotal connection requires the upper end 54 to move somewhat angularly, as indicated by a comparison of the solid line closed and dotted line open positions of the lever in Fig. 4. For this reason, the opening 55 in the cover through which the lever passes must provide suicient clearance to enable the lever 52 to move` angularly as well as downwardly. The arrangement may well be called a loose iit.

To facilitate depression of the actuating lever a round knob 66 is mounted at the top of the lever, which `knob also serves as a movement limiting means determining the open position of the closure member.

The closure member is returned to its normal closed position when the actuating lever 52 is released by a main spring 68, which. according to another feature of the present invention, is supported upon shaft 40 and is adjustable to vary the returning force applied to the closure member. The adjustment is effected in a novel manner by angular movement of the shaft 40 into desired angular position. One end I0 of the spring 68 isroperatively connected to the closure member in a suitable manner as by passage through a small opening 12 in the side wall 46, as best illustrated in Fig. '7. The opposite end is xedly secured to the shaft in novel manner by a keeper spring 'I4. The keeper spring has several turns 16 at one end and a bent over portion I8 at its opposite end passing through a small opening in the shaft 40. The other end 82 of the main spring is provided with a bent over or curved or looped portion passing between the shaft and theigenerallyaxiall-y extending portion 84 of the keeper spring. This arrangement enables the Amain spring readily Lto be assembled relative up on the shaft.

The tension of the springl 68 is adjusted by angular movement of the'shaft 40. This angular movement is effected after moving the shaft axiallyto-the right, as viewed in Fig. 7, to withdraw-the square portion r86 of an adjusting nut 88 from beneath a shoulder 90 formed in the dependent lug`44, asbest illustrated in Figs. 3, 6 and 7. Theadjusting nut 88 is xedly secured to the shaft as byknurl fit. When the desired adjustment ofA spring tension has Ybeen made, the adjustingnut is lreleased and the spring 68 pulls the vsha-ft 'back to the `leftwhere itisheld in the desired'angular position'by engagement between the square portion 860iA the nut V'and the-shoulder90.

AAs previously indicated, the spherical surface 32 of 1the closure member substantially closely approaches ywall 28and closes the opening 26 in its lnormalclosed -position but moves awayV from th'ewall and opening as it is moved .toward open position. This result is -accomplished 'by 'displacing'thecenter` line ofthe spherical surface relativeto the axis about which the closure 'membermoves This displacement maybe very slight, as about 1,454 of'an inch for a sphere having a-diameter of 11A inches. The spherical surface centerv is displaced -to the left and down Wardly relativeto. the axis of the shaft 40, as`

viewed in Figs. 4 and 8, and as indicated by the referencecharacter D in' Fig. 8. Thus,l as 'the closure member'moves clockwise, it risesfandvsub stantiallycloses the opening 26. l

The closed positiongof the closure member is determined by engagement between its :front sideA (theright side as viewed in Fig. 4) and shoulders 92 `at the sides of tongue 38 and formed inL tegralwith the cover.

`In order to deflect ejected cigarette stubs in the-groove 34 and also other material lying loosely-on top of the closure member Ainto the base and to protect the mechanism, the front side of the closure member is made solid and preferably ilat, as indicated by reference character 94. The surface 94 isso disposedA that the tongue 436 projects slightly therebeyond in the open position` of the closure member, as indicated in Fig. 5. thereby to ensure complete ejection.

From the foregoing detailed description of the invention, it vmay `be noted that the ash tray vmay bev constructed and assembled readily and economically. Itv comprises but a few parts which maybe-readily made, as 'by die casting, and which can be easily assembled. The assembly of the actuating-mechanism and particularly of the spring for returning the closure member to its closed position is simplified by the use of the mainV andv keeper springs. Furthermore, the spring tension can be adjusted easily and effectively.v In use, the closure member is` normally in its closed `positionxwhereat .it .is held. by the Vmain spring. The snuiing groove` 34 is thus at :the toprof` the trayV and at the center of therdepressed portion so that cigarettes may vbe easily placed vintothe groove and extinguished. Space iszprovided for more than one ,cigarette so that thefclosure-memberneed not be opened each time acigarette is placed therein.

`In orderrto open :theclosuremember and to groove,-it is .only necessary to depress the knob 6 66, whereby the actuating'lever .52 is moved generally downwardlyanditslower Lendis moved to ward 4the center of the tray. The lever directly moves the closure member `:ill-against the tension of the spring 68, the-tension'of which is slightly increased during the opening operation.' Ciga rettes in the snufng groove are ejected fbythe ejector vtongue 36 and either fall .directly into the receptacle space I4 or upon the flat front surface 94fof the closure member which deects them into the space. When the'actuating lever is released, the closure member is returned to its closed position bythe spring 68.` -f' In the closed position, the closure-member substantially closes theopening but when -it is moved toward its open position, it is movedl away Vfrom the Mopening defining structure by reason of the displacement or offset vbetween the centerof the sphere and the axis about which the sphere moves.` 1 While but` asingle embodiment of the inven tion has `been described in'detail, `it should be. un'- derstood that the specificdetailsthereof are 'not intended to fb'e limitative of the inventionexcept insofar as set forth in the accompanying claims. It should be understood 4also thatr while the invention has been described in connection with an ash tray, this term is used in Va broad sense-to cover not only cigarette .ash trays but also other typesk of smokers accessories provided withA an ash receiving space. y
