ELECTRIC HEATER.

To all whom it may concern: l

Be it known that I, PHrLrr F. APPEL, citizen of the United States, residin at Seattle, in the county of King and tate of lVashington, have invented s. certain new and useful Improvement in Electric HeatersMo which the following is a specification.

invention relates to improvements in electric heaters of that class which areemployed for igniting cigars, and`the method of ignitingsaidv cigars, and the object of my invention is to provide an electric heater which shall be of such form of construction as will provide passageways for air therethrough whereby the end of a cigar to be lighted may 'be disposed at the outlet end of said electric heater and the act oi draw- A ing air through the cigar will cause air to iiow through said passageways wherein the air will be heated to a high temperature, by a heating conductor disposed within said electric heater, which heated air will quickly I accomplish this object by devices illustrated in the accompanying drawings, whereinl Figure 1 is" a view of my invention in front elevation;

Fig. 2 is a view in longitudinal mid-section on broken line'2, 2 of Fig. l;

Fig. 3 is a view in cross-section on

broken line

3, 3 of Fig. 2; and

Fig. 4 is ay viewin longitudinal mid-secl tion showing a modified form of details of parts, a hollow body portion my invention.

Referring to the drawings, throughout which like reference numerals indicate like 5 of cylindrical form is made of retracto material that is a non-conductor of electrlcity, as porcelain or plaster of Paris, and embedded therein are two electrical conductors 6 and 7 which are disposed to ext-end from circuit connectors '8 and 9 (with which they are respectively connected) each to and through the back end wall 10 of the body portion 5.

The hollow heating element of cylindrical form, comprising the end portion 12, end portion 13, and the annular body portion 14, is made of refractory material that is a non-conductor of electricity, the inner space 15 of said heating element being flared at its end portion 12 -to adapt it to guide the end o a cigar into the inner space 15.

Embedded within the circular walls of Applicationl led August 27',

Specication of Letters Patent. .Patented Feb. 18, 1919.

the inner space 15, with a part of its surface exposed within the inner space 15, is an electrical heating conductor 16 whose ends 17 and 18 are extended to and through the end portion 13.

Disposed to surround the heating element thereby forming a passageway for air from the exterior of said heating element throughthe holes 20, thence through thepassageway 22, formed by the tube 19 and the body portion 14, thence through the openings 21 into the recess 15.

The heating tube 19 may be element including the metal conductor 16 will make contact with the circuit wires 6 and 7.

The construction of my invention as shown in Fig. 4 is similar to the construction shown 1n Figs. 1, 2 and 3r with ,the exception of the4 winding 'of the heating conductor and the construction of the body portion of the heating element.

ln Fig. 4, the electrical heating conductor 23,' like the conductor 16 of' Fig. 2, with part of its surface exposed within the inner space 24, is embedded within the lcircular walls of the inner spaces 24 and is extended to and embedded within the annular body portion 25' with a part of. its surface disposed snugly tol t within l the inner space 11 of the loody/portionv whereby the ends 17 and 18 of the heatingl -forming a circuitv extending from the outer surface of the heating element to andA within the inner space 24 thereby aording a larger exposed surface of the conductor' 23.

Disposed to extend through the 'body portions 25 are a plurality of holes 27 which form a passageway between the passageway 26 and the inner space 24.

The body portion'together with the electrical element may be inclosed within any suitable casing, not shown, whereby it may be adapted for use to ignite cigars.

The heating elements including the conduct'ors 16 and 23 may be made of any of the different materials that .are well known to those skilled in the art.

l The opera'tion of my invention as disclosed 'in Figs. l, 2 and 3 is as follows: rIhre circuit connectors 8 and 9 are connected by welll known means to a source of electrical current, not shown, thereby causing a current of electricity to iiow through the electrical heating conductor 16 whereby the conductor 16 is heated to a high'temperature whereupon the end of a cigar is inserted into the inner space 15 and by drawing upon said cigar air will be caused to flow from the exterior of the heating element through the' holes 20, thence through the passageway 22, thence through the openings 21 into the inner space 15 whereupon the `air is heated to a high temperature and is drawn directly upon the end of the inserted cigar causing it to be ignited.

'Ilhe operation of the device as disclosed in Fig. 4 is as follows: The circuit connectors are connected in a similar manner to the connectors 8 and 9 of Fig. 2 causing the heating conductor 23 to be heated to a high temperature whereupon the end of a cigar is inserted within the inner space 24 vand by 'a drawing upon said cigar air will 'be caused to iow from theexterior of the heating element through the holes 20 thence through the passageway 26, where it is heated to a'high temperature, part of which heated air being drawn through the holes 27v and part of which heated air being drawn through the openings 21, into haagse? the inner space 24 where it is again heated to a still higher'temperature within the inner space 24, from which inner space 24 the heated air is drawn directly upon the end of said cigar causing it to be ignited.

Obviously many changes may be made in' the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

What I claim is:

An electric heater of the class described, which embodies a body portion, and an electric heating element disposed within said body portion, said heating element being provided lwith a passageway for air adjacent one end portion thereof, another passageway for air communicating with the rst named passageway and -extending to the rear end portion of'said heating element and thence extending through the central portion of said heating element to the exterior thereof, said heating element also being provided with passageways for air extending from the second named' passageway to the passageway extending through the central portion of said heating element whereby air may be Iheated during its passage through all of said passageways.

In witness whereof, I hereunto subscribe my7name this 10th day of August A. D. 191

PHILIP F. APFEL.
