14 Claims.

Among the common articles of smokers accessories are supporting trays for holding lighted cigarettes, cigars or pipes and for receiving loose ashes, tobaccoand refuse. It is important that these be made available in such number and so readily distributable that their use will be encouraged and ashes not be spilled and so that lighted cigarettes or cigars will not do damage to furniture on which they might be carelessly laid. Inexpensive devices of this sort have come into very general use but there is an unfulfilled demand for such articles of improved character producible at so low a cost that they may be freely purchased by the user or even distributed for advertising.

It is furthermore desirable that such devices be kept clean and free from soot, stain andother unpleasant remainders of use. One great difficulty with previous devices has been that in an effort to produce a low cost article they have been made so light as to be instable and apt to be overturned and the contents spilled. My invention contemplates such articles so constructed as to be of maximum serviceability and of minimum cost.

While paper or cardboard trays are generally inflammable or too combustible for sparks, coals or hot ashes, I am able in accordance with my invention to construct from inexpensive pulp stock such as that of wood fibre, by molding to smooth hard surface forms which are capable of remaining upright and which will support not only cigarettes but even larger articles, such as cigars or pipes.

My invention further contemplates making such articles as shells 'or members which can be assembled or nested. This offers a great advantage in that it provides for ash trays of considerable weight and thickness in assembly, while consisting of detachable replaceable members which can be removed when full or soiled and can be thrown away and readily disposed of. These and various other advantages will more fully appear from the following disclosure and description of the constructions involved. A characteristic embodiment is shown in the accompanying drawing which well illustrates the principles, and while illustrative and capable of modification and variation is a convenient and commercially practical structure. In the drawing:

Fig. 1 is' a view showing a central section through a tray in accordance with my invention.

Fig. 2 a general view of such an article in use, and

Fig. 3 a side elevation illustrating detachability.

In the form shown the article is externally of generally frustro-conic shape having a side flaring outer wall I having an external flange or base 2. The upper edge of the wall I is molded as at 3 and downturned as at 4 to an annular bottom 5 which is raised sufficiently above the plane of the base flange 2 to provide air spaces and thus afford insulation for any surface T on which the tray may be resting.

-Within the bottom portion 5 is another annular ridge constituting a parapet and consisting of an outer wall 6 and an inner wall 1 disposed in general angular relation so as to form a circular ridg'e on which a cigar or cigarette may be supported as shown in Fig. 2. An integral bottom 8 is provided within this parapet so that the whole constitutes a central crater-like cup or pocket for loose ashes. The bottom 8 is also raised above the base level of the flange 2 and preferably in the same plane as the annular bottom 5.

The outer edge 3 of the enclosing conical walls I and 4 is crenelated as at 9 by depressions having inclined bottoms l8 which slope in towards the edge ll formed by the walls 6 and I. The angle of the portion I is such as to line up with this edge ll thus firmly supporting the cigar or cigarette (indicated at C) with its lighted end overhanging the edge II and disposed above the bottom 8 of the crater-like center.

The members being thin, uniform and closely nesting may be tightly assembled and readily handled but the upper member may be easily detached as indicated in broken lines, Fig. 3, by prying up on the flange 2 of the edge, exposing a fresh surface. The detached member can be then thrown away with its contents. Additional units can be added as desired to create or maintain any desired thickness or weight in the total assembly. a

The individual tray-units may, of course, be made of any desired thickness and each being complete in itself may be used individually where desired. The channels and ridges are so proportioned and of such angularity that they have ready draught from the mold and as above described nest closely where assembled in multiple use or in packing for shipment. These articles may carry any desired lettering or decorating and this may be done in the molding or may be applied as printing, as for example, in the outer face of the wall I (as indicated in Fig. 2) or the inner face of the bottoms 5 and 8 (not indicated).

The fibre mix may be of any convenient materials and proportions and may include fire resistant-materials such as asbestos or fillers such as infusorial earth or clay or sizings or impregnaing of pulp of substantially uniform thickness tions, such as silicate of soda and like fire proofing or fire resisting materials. By molding on toraminous dies these articles may be made with great uniformity and with any desired surface finish as by pressing in the dies which may be heated where a particular resistant surface is required. The articles may be variously shaped and proportioned as may be desired, all without departing from my invention it within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A smokers accessory comprising a plurality of relatively thin interfitting tray-like members of substantially uniform thickness and formed 'with a crenelated external annulus of inverted V-shaped cross section, and an inner annulus 01 like section concentric to said outer annulus, each member having a bottom integral with and connecting said annulae and vertically spaced from the bottom base plane of the outer annulus, each member being removably interfitted with those next adjacent.

2. A smokers accessory comprising a plurality of relatively thin interfitting tray-like members of substantially uniform thickness and formed with a crenelated external annulus of inverted V-shaped cross section, and an inner annulus or like section concentric to said outer annulus but having its upper edge disposed below that of the outer annulus in line with the bottoms of the crenelations, each member having a bottom integral with and connecting said annular: and vertically spaced from the bottom base plane or the outer annulus, each member being detachably interfitted with those next adjacent.

3. A smokers accessory comprising a plurality of interfitting tray-like members of fibrous material each consisting of pulp 01 substantially uniform thickness having an external annulus of inverted V-shaped cross section having radial cren elations in its upper edge, and an inner annulus oi! like section concentric to said outer annulus,each member having a bottom integral with and connecting said annulze and vertically spaced from the bottom base plane of the outer annulus, each member being removably interfitted with those next adjacent.

4. A smokers accessory comprising a plurality of interfitting tray-like members of fibrous material each consisting of pulp oi! substantially uniform thickness having an external annulus o! inverted V-shaped cross section having radial crenelations in its upper edge, and an inner annulus of like section concentric to said outer annulus but having its upper edge disposed below that of the outer annulus substantially in line with the bottom of the crenelations, each member having a bottom integral with and connecting said annulae and vertically spaced from the bottom base plane of the outer annulus, each member being detachably interfitted with those next adjacent.
