13 Claims.

'Ihis invention relates to ash trays and more particularly concerns improvements in ash trays embodying means for extinguishing the burning tip of such smokers articles as cigarettes and cigars.

Probably the most common method of extinguishing articles of this nature is to crush the burning tip against a non-yielding surface such as an ash tray bottom. oftentimes thisfails to extinguish or remove every spark from the stub and it will continue to smolder for some time.

causing annoyance and fouling the atmosphere.v

ing distraction and delay. If careful attention is not given, the stub may remain partially unex` tinguished and be the cause of annoyance.

The principal aim of the present invention, therefore, is to provide an ash tray embodying simple means for extinguishing the burning tip of a smoking device operable merely by contact with the burning tip itself, the device being positive and thorough in action and requiring practically no effort or attention in use.

Another object is toprovide a device of the foregoing character which in operation is contacted by the burning tip of a smokers article and serves to grind off or disintegrate all ignited portions to remove the same entirely from the stub;

Another object resides in the provision of a vertically reciprocable extinguishing device suitably means attractivelyl and cooperatively arranged therewith for supporting a cigar or cigarette adjacent thereto above the receptacle bottom in such a position that should the article become dislodged therefrom it must necessarily fall into the receptacle.

Other objects reside in the provision of an extinguisher having a spring urged reciprocatory member in which the spring is of a tensionadapting the same to yield easily under slight pressure imposed through a lighted smokers article and in which the spring acts additionally as a cushion to prevent concussion or noise during operation; in the provision of a device embodying an extinguisher head adapted also to serve as a handle for supported in an ash tray or the like and having transporting the device; in the provision ofan' extinguishing device secured to a receptacle and serving vas fastening means for an `outstanding ,support adapted for receiving a lighted smokers article; and in the provision of an ash tray em- 5 bodying an extinguishing device having few and simple inexpensive parts adapted-to be assembled into a complete, attractive device easily and rapidly without special skill so that the device can be manufactured and sold at low cost. 10

Other objects and advantages will become apparent from the following description and from the accompanying drawing', in which:

While the invention is susceptible of various modifications and alternative constructions, I have shown inthe drawing and will herein describe in detail the preferred embodiments, but it is to be understood that I do not thereby intend to limit the invention to the specific forms disclosed, but-intend to cover all modifications and alternative constructions falling within the spirit and scope of theinvention as expressed in the appended claims. 45

In one form of the invention, shown by way of example in Figs. 1 to 6, a conventional ash tray I5 having a-convex bottom I1 axially supports an extinguisher device generally indicated by the numeral I8. cooperatively arranged in an attractive manner with the extinguisher device is a holder I9 adapted for conveniently supporting a lighted smokers article such as a cigarette or cigar directly above the bottom I1. a

vThe extinguisher is conveniently arranged to be engagedA by .the burning tip of a smokers article and is operative to remove or disintegrate all ignited particles of the tip upon the exertion of only slight axial pressure applied through the medium of the article itself. Thus, the device is simple in operation and no particular care or attention is required in using it so that distraction while extinguishing a cigar or cigarette is reduced to a minimum.

In one practical form, the extinguisher I8 may embody a mount comprising a vertically extending .tubular post 20 conveniently secured to the ash receptacle. To this end, the lower end of the post is formed as a threaded portion 22 of reduced diameter adapted to ilt within a suitable aperture 23 provided centrally in the tray bottom I1.

Snugly encircling the upper end of the reduced portion 22 is a washer 24 providing a substantial bearing opposing the upper face of the tray bottom. Screwed to the lower end of the portion 22 is a nut 25 adapted for drawing the post into rigid engagement with the tray bottom by clamping the margin dening the aperture 23 tightly between the nut and the washer 24.

In the present instance, the extinguisher serves also as fastening means for the holder I9. As seen in Figs. 1 and 2, the holder is of substantially U-shape having an axially apertured base 21 and two outstanding legs 28 terminating in arcuate receivers 29. Conveniently the base 21 is tted about the reduced post portion 22 between the washer 24 and the tray bottom I1 so that the same is rigidly fastened coincident with attachment of the post 20 (Figs. 3 and 4). Through this arrangement of the holder I9 a smokers article supported thereby will be wholly' over the tray and must fall therein should it be accidentally dislodged.

Supported for rotary reciprocable movement relative to the post 20 is an extinguishing head 30 having a broad upper face 32 and a lower face embodying a central axially bored hub 33. Fitting tightly about the hub is the upper end of a tubular guide casing 34 which is of a length to extend slidably about the post 20 even when the head is in extended position. If desired a thin depending marginal skirt 35 may be provided near the margin of the head.

The means for imparting rotary motion to the head comprises in the present instance a spiral screw 31 fitting at its upper end securely within the bored hub 33. At its lower end, the screw lits slldably within the tubular post 20. In one preferred form, the screw 31 may be of the type known as a square spiral (Fig. 6), and the upper end of the post 29 may be swaged to provide a square guide 38. It will be apparent, therefore,

' that as the screw moves reclprocally relative to the post upon movement of the head 30, it will be forced to revolve upon its axis in passing through the guide and the head will be rotated accordingly. Desirably, the lower end of the bore within the post is of slightly enlarged diameter forming a shoulder 39; and a stop collar 40 adapted to fit within the bore enlargement is secured upon the lower end of the screw. Abutment of this stop collar against the shoulder will limit upward movement of the screw and will prevent its withdrawal from the post. Thus, the extinguishermay be. utilized as a convenient handle in shifting the device.

Maintaining .the head 30 in normally extended relation relative to the post 29 is a spring 42 preferably ofthe expansile helical type and of a tension calculated to yield upon the application of slight pressure upon the head. In diameter the spring is slightly less than the interior of thetube 34 which thus serves as a retainer therefor. At its upper end the spring bears against the hub 33, while its lower end rests upon a shoulder 43 formed on the post 20 adjacent the guide 38. Thus, when the lighted tip of a smokers article such as a cigarette is pressed lightly downwardly against the face 32, the spring will yield and the head will be caused to descend from a position as seen in Fig. 3 toward a position as indicated in Fig. 4. At the end of the downward reciprocation of the head the spring reaches its limit of compression and provides a noise and shock absorbing cushion between the head and the upper end of post 20. When pressure is released upon the head, the spring 42 will cause the same immediately to resume its normal or extended position relative to the post.

In the present instance the means for removingr a burning tip comprises a plurality of radially arranged, equally spaced kerfs 45 (Fig. 5) on the face 32. These kerfs, it will readily be understood, have an abrasive action upon rotation of the head designed thoroughly to disintegrate the tip so that every vestige of ignited material will be removed from the stub.

, Since the extinguisher is most easily operated and the most eifective results are obtained from the abrasive action of the kerfs 45 when .the burning tip is centered upon the face 32 as pressure is applied, I provide means designed to force the tip towards the center of the face should the tip at the commencement of operation be inadvertently placed toward the outer margin. Herein this means is shown as comprising a spiral kerf 46 running from the periphery toward the center oi the face 32. As will be observed from Fig. 5, the spiral 46 'runs counterclockwise toward the center, when .the head rotates clockwise, herein a condition incident to descending movement. Thus, should the burning tip be placed toward the margin of the face 32 it will quickly be forced toward the center by virtue of the spiral action imparted by the spiral kerf. A further aidv in centering the burning tip may be provided by shaping the face 32 concavely (Figs. 3 and 4).

As seen in Figs. '7 to 9, inclusive, the invention may embody an extinguisher indicated generally by 48, including certain modifications of structural detail but adapted for 'similar operation as the extinguisher I8. As shown, the extinguisher 48 may be applied conveniently to a tray having a flat bottom 49 although, of course, it may be secured to a tray of any other shape. as desired. Thus, a vertical tubular post 50 having an externally threaded base 5I is tted within an internally threaded annular upstanding flange 52 formed on the tray bottom 49. If desired, the base of the post may be bored and'internally threaded to receive a lock screw 53.

Cooperative arrangement between the holder I9 and the extinguisher 48 is procured by equipping the upper end of the post base 5I with a radial flange 54 serving to clamp the holder base against the upper edge of the ange 52 coincident with securing the post in place.

Resiliently supported in spaced relation above the upper end of the post 50 is an extinguisher head '55 and a yieldable helical spring 51 is mounted for normally maintaining the spaced relative position of these two members. Similarly.as in the extinguisher I8, rotary motion is imparted to the head 55 by a spiral screw 5l Asbestseeninrigalanddthepostlhaanear its upper end coaxial transverse bores each providing a housing for a ball Il which is held in place by a plug 'I'he balls M provide bearings fitting against opposite faces o f the screw i! and cause the screw to rotate as the same is moved reciprocally in the bore .I upon movement of the head 5l. This ball bearing arrangement has the advantage over the square guide 34 in that less i'riction is developed and somewhat smoother operation results. More-l over, wear is a very negligible factor where the ball guide is employed. A stop may be conveniently provided at the lower end oi' the screw I8 by discontinuing the spiral short of the end so that withdrawal will be prevented by a locking engagement with the balls 64 (see Fig. 7).

An enclosing guide tube 61 nts snugly about the periphery of the hub B and extends downwardly into slidable engagement with the periphery of the post in. In order to secure a. tight flt oi' the tube 81 about the hub 80, the latter may be provided with a rabbeted groove 68 adapted to receive a bushing 69. This bushing may be dimensioned to provide an exceedingly snug driven dt about the screw 58 which is thus rigidly held in the head. Furthermore the bushing is calculated while being driven into place to spread slightly the surrounding margin of the hub 60 so as to cause the latter to grip tightly the upper end of the tube 61. In this manner the parts are thoroughly united and are capable of withstanding rough usage without separation.

If desired, the head I may be 'provided with a flat face which may have a. similar arrangement of radial and spiral kerfs as seen in Fig. 5.

From the foregoing, it will be observed that the invention provides convenient and eillcient means for quickly extinguishing a smoker's article without requiring any special skill or adeptness in operation. 'I'he user need only place the lighted tip of a smoker's article against the extinguishing head and exert slight pressure upon the stub perpendicularly to the head in order to effect rapid and thorough removal or extinction of all burning material. The device embodies few and simple parts that may be assembled quickly without special equipment or peculiar skill, and requires no mechanical .ttention in use.
