in Cana November 17, 1933 I 10 Claims.

This invention relates to ash trays and more particularly to means for extinguishing lighted cigars and cigarettes.

Heretofore considerable damage has been caused by lighted cigars and cigarettes falling from the rests of ash trays and it is therefore an object of the invention to provide an ash tray embodying a rest for the cigar or cigarette in which means are incorporated, actuated by the heat of the lighted cigar 'or cigarette, for extinguishing the fire thereof, by a snufiing or smothering action.

It is also an object of the invention to provide a cigar or cigarette rest in which the lighted cigar or cigarette is firmly grasped and held against displacement therefrom until the cigar or cigarette has become extinguished. I

Additional objects, advantages and features of invention will be apparent from the following description and accompanying drawing, wherein Figure 1 is a fragmentary side elevation of an ash tray equipped with my invention.

Figure 2 is a fragmentary top plan view thereof. Figure 3 is a sectional View on the line 33 of Fig. 2.

Figure 4 is a top plan view of a modification. Figure 5 is an end elevation thereof. Figure 6 is a cross section on the line tii of Fig. 4.

Figure 7 is a top plan view of a further modification.

Figure 8 is an end view thereof.

Figure 9 is. a cross section on the line 99 of applicable to both. The rest comprises a plate It having a slight curvature upwardly as viewed in end elevation, the curvature being such as to 50 permit the laying of a cigar or cigarette longitudinally therewithin. The plate [4 is afilxed to the rim H in any approved manner, as by sol dering, brazing, or small rivets may be employed. The rest is of a length to project well over the 55 tray I0, and the plate M is cut away as at {5,

In carrying out the invention I make use of (hi. isi-si 1 defining a medial tongue it. The tongue I6 is bent downwardly from the plate, at a slight angle. and stops short 'of the base i! of the tray, where it is given a right angular bend, defining a foot 18. The foot l8 aifords a support for a cigar or 5 cigarette snufier H. p

.The snuffer H9, in the present instance, is of substantially U-shaped formation, the bight portion' 20 of which is positioned upon the foot i8, where it is'secured by soldering, brazing or rivet- 10 ing. The snuffer thus constructed provides a pair of spaced leg members 20 disposed upon opposite sides of the tongue it.

The snuifer i9 is formed of thin, flexible bimetal and the legs 20 extend a distance above 15 the tongue l6, and normally occupy a position so as to readily receive a cigar or cigarette there- 'between. Obviously, when the lighted cigar or cigarette is laid upon one of the rests I2II3 with the burning end disposed over the tray ill, the 20 heat radiated from the cigar or cigarette will cause the legs 2! to swing or fiex toward each other to such an extent that the buming portion of the cigar or cigarettewill be extinguished by a snuifing action. It should also be noted that when 25 the legs M are moved toward each other, the cigar or cigarette will be firmly held upon the rest without liability of displacement therefrom, and will be so retained until the thermostatic action of the snufier ceases to function, which would only occur upon cessation of heat developed by the burning tobacco.

In Figures 4, 5, and 6 a modification of the device is shown, in which the tray 22 supports a rest 23 upon one edge of which a pair of bearings 20 are integrally formed. The rest 23 is preferably so shaped as to insure that the cigaror cigarette when laid therein will be disposed adjacent the bearings 24' so as to be in a position to be readily acted upon by a snufl'er, as will be 40 described. I

Journalled-within the bearings 24 there is a small shaft 25, which has integrally formed upon one end thereof a hood-like member 26. The hood 26 is slightly curved, conforming to the shape of a cigar or cigarette and cooperates with the rest 23 in extinguishing the cigar or cigarette. The opposite end of the shaft'25 has an enlargement 21 maintaining the shaft in position. A thermostatic spring 28 is provided, in the present instance being shown in the form of a spiral, the inner end of which is secured to a pintle 29, the outer end being fixed to the hood 26. The pintle 29 is loosely journalled in a bearing or guide block 30 on the flange 3| 01 the tray. The

spring 28 normally has a position in a plane at a slight angle to the rest 23 so that the lighted end of the cigar or cigarette will engage the spring when laid in the rest. In operation, when the springis influenced by heat, the tendency will be for the spring to extend itself in a longitudinal direction, and since such action is restricted, due to anchorage of the shaft 25, the inner end of the spring will tend to move axially away from the heat. This axial movement will be restricted to a limited degree by the pintle 29 and bearing 30, thereby imparting a rotary movement to the shaft 25, swinging the hood 26 into a position to engage and smother the fire of the cigar or cigarette.

In Figures 7, 8, and 9 a modification of the hood is shown. In this form, the hood 32 is of a length substantially that of the rest 33 so that a greater portion of the cigar or cigarette will be grasped during the smothering or stifling action. In this form the shaft 34 may be formed integrally with the hood and the bearings 35 so spaced as to receive the hood therebetween. The

bearings 35 in addition to journalling the shaft, also limit end thrust of the shaft under action of the thermostat.

It will of course be understood that as soon as combustion ceases, the parts return to normal position upon cooling of the thermostatic elements.

If found necessary, in the form disclosed in Fig- 'ures '7, 8 and 9, the flange 36 of the tray may be provided with a suitable foot 31 to prevent tip-.

the hood member into position with the cigar or,

cigarette to smother and stop combustion.

2. A safety-ash tray, consisting of a rest for cigars or cigarettes, a movable member associated therewith and a heat responsive member so arranged that when the heat from a lighted cigar or cigarette nears the heat responsive member, it acts upon the movable member forcing .it into position relative to said cigar or cigarette to stifle and stop combustion.

3. In a safety ash tray, a rest, a thermostatic element, a hood or the like so associated therewith as to be acted upon when the heat from a burning cigar or cigarette nears the thermostatic element to smother or extinguish the cigar or cigarette and so designed that upon completion of said action the parts will return to normal position.

extinguish, stifle, suffocate or strangle combus- 1 tion of said cigar or the like.

5. A rest for a lighted cigar or the like comprising a heat responsive element cooperative 'with the rest for gripping, smothering and stifling combustion of the cigar.

6. In a safety ash tray, a rest for a lighted cigar or the like, said rest extending inwardly over the tray, a substantially U-shaped bi-metallic member supported within the tray, the legs of the U-shaped member being disposed upon opposite sides of the rest and terminating above the rest and adapted to embrace the cigar, whereby said leg members will be forced toward each other under action of combustion of the clgar.
