1 Claim. (Cl. 43-427) This invention relates to a smoke dispensin device, adapted for use to discharge smoke for exterminating gophers or rats, hich inhabit ground burrows or pockets.

The principal object of this invention is to efficiently discharge a strong blast of smoke into burrows or pockets formed in the ground, to drive rodents or other ground inhabiting animals out of their lairs or to overcome and asphyxiate them, and to dispel bees and similar insects.

Also, it is an object of this invention to provide means for discharging a constant and strong blast of smoke for fumigating trees, bushes and other shrubbery and for utilization and employment as a frost repelling medium, to protect the fruits of the trees and bushes.

Another object of this invention is to employ means for compressing air and discharging the air within the casing to aid the combustion of fuel placed withinthe casing and to discharge smoke from without the casing.

A meritorious feature of this invention resides in the provision of a bellows bracketed to a combustion chamber and adapted to discharge air through the combustion chamber to incite and aid combustion of the fuel and to conduct air transversely through the casing, providing a Venturi action to suck the resultant smoke from the fuel out of the combustion chamber and discharge the smoke out of the casing.-

Another meritorious feature of this invention resides in the provision of a discharge pipe dctachably secured to a connecting pipe communicating with the bellows and the casing and transversely extending through the casing to a point without the casing for discharge of the smoke from the casing to the outer atmosphere.

Another feature of this invention is the provision of a primary source of air for combustion, which includes an angular pipe extending laterally from the bellows and terminating at a point adjacent the combustion chamber.

With these ancillary objects and other meritorious features in view, this invention comprises certain structural features and arrangement of parts as will be more clearly apparent, as the following description proceeds and in view of the accompanying drawings, wherein:

Figure 1 is a side elevational view of a smoking device, constructed according to the principles of this invention;

Figure 2 is a top plan view of the device shown in Figure 1, with the cover removed and,

Figure 3 is an enlarged structural view of the means utilized to discharge the smoke from the casing and comprises a tubular discharge pipe.

Referring now more particularly to the draw ings, wherein an embodiment of this invention is shown, for illustrative purposes, and wherein similar characters of reference refer to similar parts throughout, there is shown casing Ill, having its top end open and adapted to a detachably covered by a cover member 12. Centrally disposed and formed in the bottom end, M, of the casing is an aperture 16, around which is secured, within the casing, a domeshaped wire screen. This screen l8, forms a fuel bed for the fuel and defines a combustion chamher within the casing.

, secure the connection of r having laterally extending ends 3|] and Secured to the side of the casing, adjacent the open end thereof, is a discharge spout or tube 20, of any suitable size and preferably conical in shape, having its larger end secured to the casing by means of an apertured annular flange 22, formed around the periphery of the enlarged end of the spout. Conventional means are provided to secure the spout to the casing and include telescopic screws or bolts 24, which are inserted through the apertured flange 22 of the spout and through the side of the casing.

Secured to the casing, on the opposite side from the spout 2B is a bellows are provided for attaching or securing the bellows to the side of the casing and include a pair of oppositely disposed brackets 28,30, utilized to ing, and comprise an elongated plate, of a suitable width to space the bellows from the casing, 32. Ends 30 are bent at right angles to the longitudinal plane of the bracket plates 281 and are secured to the cooperating side 34 of the bellows 26 by means of screws 40, which are inserted through apertures in the angular ends 30 and penetrate into and are threaded into the cooperating side 34 of the bellows. Angular terminating sections to conform to the cylindrical contour of the easing and to be seated flush thereon. Telescopic screws, or other suitablemeans, 42, are employed to secure the arcuate extensions 32 to the casing l0 and are inserted through apertures formed in the arcuate ends 32 and the casing.

The bellows 26 comprises a pair of which are retained in operative relation, by means of a flexible covering, of suitable material. The material 34 and 36 forming an air-tight chamber therea cylindrical 26. Suitable means the bellows to the cas- 32 are arcuate in cross-section oppositely disposed cooperating plate members 34 and 3B,

46 covering the cooperating plates between, when the plates are extended, is fixed or secured to the sides of the plates 34 and 36 by suitable means, such as rivets 48.

Disposed within ing sections 58 of the bracket 54 and inserted through the bottom of the casing. V

oppositely disposed from the conical spout and in horizontal alignment therewith is a suitable aperture formed inthe opposing sidewall of i and secures wall of the casing.

The fuel placed on the fuel bed is then ignited and the cover I2-is replaced on the top of the casing. The bellows 26 is compressed and air is sucked in the bellowson the release stroke, when the" 34 and 36 are urged apart by the spring 72. When the'cooperating plates are end 52,
