This proof a p1pe bOWL I m ke I P08811016 for the jection, containing the heating element 20 at lgIlltlOIl body and therefore the con nse its lower extremity, is of such diameter and o 7 column of air impinging thereon, to be passed, configuration as to permit of its insertion into over different: portions of thetobacco m the the bowl of a pipe 21. This projection sho ld we also be of a length suilicient to bring the bottom thereof, and hence the heating element 20, into contact with the tobacco within the bowl no matter how small the amount of such tobacco within the bowl,

The heating or glow element 20 compr ses a series of loops of a thin and highly resistant wire embedded in the heat resisting material of projection 19 and having its terminals joined to conductor wires 13 and 14 which are led from the cable 15, through housing 12, handle 10, elbow 11 to the heating end of projection 19. As illustrated in Fig. 4, the glow element is formed in a series of parallel loops embedded in the dielectric substance of member 19 so as to present a heating surface capable of setting fire to the tobacco with which they come into contact.

In order that the tobacco in the pipe may be effectively ignited it is necessary that a free supply of air to support combustioirbe available. To provide a means of circulation for such air through the tightly packed tobacco and igniting device I construct my new device with a free passage opening to the air at a distance from the glow member. In the embodiment illustrated in Figs. 1 to 1, I provide an aperture 21 in the top of elbow 11 through which the passage of the tubular member co-mmunicates with the atmosphere. Air is thus sucked through this aperture, drawn in the form of a coluinnthrough the inner passage of member 19 and through the bottom opening of said member out through the pipe stein. It will be obvious, of

course, that the passage may have its aperture 21 anywhere in the member 19 so long as it is a sufi'icient distance from the glow member to cause the ignition air to impinge on the glow body only after it has been formed into a flowing column as distinguished from a locally swirling mass. I

In F1. 5 I have illustrated a modified form of my new device. It differs from the embodiment hereinabove described in that its metal casing 22 to which is attached the heat resisting projection 23 corresponding to the member 19 of the form first described, is of cylindrical form instead of an elbow. The apertures 24 correspond in their function to V the aperture 21 of F 1 and 2. These apertures are located at a distance from the heating end of member 23 suiiicientto bring them outside the bowl of the pipe when the device is inserted therein. The apertures 21 and 22, so long as they are free of the pipe bowl, and in contact with the free atmosphere, will suflice to provide the free circulation of air in the manner hereinabove described necessary for a speedy and efiicient ignition of the tobacco within the pipe. It is obvious that any number of such apertures 21 and 2 1 may be I provided in the surfaces of the casing members 11 and 22.

In Fig. 6 I have illustrated a still further embodiment of my invention. The device there shown comprises a metal casing 25 having attached thereto tubular section 26 of a non-inflammatory material and thermally and electrically insulated from said casing. The glow element 20, located at the end of said tubular section, has one of its conductor wires 27 supplying current thereto connected to the casing 25. The second conductor wire 28 is led through the central passage of tubular member 26, through the metal casing insulated therefrom by the portion of member 26 projecting into the interior of the casing shown at 30, to its terminal in cap 29. The tubular section 26 is of such dimensions that its exterior diameter is somewhat smaller than the average bore of a pipe in order that the section may have a freedom of movement when inserted into the bowl of a pipe, to permit of the glow body, and therefore the heatv emanating therefrom, being played over the surface of the tobacco in a manner similar to the movement of the flame of a match over the surface of the tobacco within the bowl when the match is passed and repassed over the bowl opening. Furthermore, the small diameter of the tubular section adapts the device to use with any size pipe without restriction by its bore. As in the einb-odiii'ients hereinbefore described, the

length of the tubular member 26 should be such that the device may be used to light a partly filled pipe.

In all of the embodiments illustrated it is obvious that the handle supporting the elbow in one instance, and the tubular sections in the others, should be located as nearly beyond the sphere of heat radiation of the glow body as possible.

I claim: I j

1. An electrical ignition device comprising a handle, a casing a projecting head of a heat resisting material attached thereto adapted to enter the bowl of a tobacco smoking pipe and having an inner passage from the bottom to at least a point near the top thereof, a heating element in said head comprising a plurality of wire loops embedded in the heat resisting material of said head and having their extremities outwardlyexposed therefrom, and electrical conductors in said head and casing in engagement with the ends of said heating element, said inner passage being in communication with the atmosphere by means of an aperture in said casing.

2. An electrical ignition device comprising a handle, a casing, a projecting head of a heat-resisting material attached thereto adapted to enter the bowl of a tobacco smoking pipe and having an inner passage from the bottom to at least a. point near the top thereof, a heating element mounted across the open bottom end of said head and comprising plurality of wire loops bent around portions of and anchored in said bottom end hso of said head, the active portions of said heating element which are in contact with the tobacco in the pipe lying in the direct path of air drawn through the saidpassage, whereby the air current impinges against the rear surface of said portions of the heating element and then flows through the tobacco, and electrical conductors in said head and casing in engagement with the ends of said heating element, said inner passage being in communication with the atmosphere by means of an aperture in said casing.

3. An electrical ignition device comprising having an inner passage from the bottom to at least a point near the top thereof, a heating element mounted across the open bottom end of said head and comprising a plurality of I wire loops .bent around portions of and anchored in said bottom end of said head, the active portions of said heating element which are in contact with the tobacco in the pipe lying in the direct path ofair drawn through the said passage, whereby the air current impinges against the rear surface of said portions of the heating element and then flows through the tobacco, and electrical conductors in said head and casing in engagement with the ends of said heating element, said inner passage being in communication with the atmosphere by means of an aperture in said casing.
