PORTABLE ELECTRIC HEATER.
Specification of Letters Patent. Patented Jan, 21, 1919 Application mea February 2o, 191s. serial No. 218,235.
tric, heater of such a size, shape and ar'- rangement of parts that it may be readily and safely carried in a receptacle, such as a trunk or bag, and may be readily attached to an electric light socket without disconnecting, or removing, lthe glass or porcelain shape usually carried thereby.
In order that an electric heater may be suitable for personal transportation, as described above, it must be compact, light in Weight, so arranged that the delicate parts thereof will be protected from breakage, must overcome the necessity of the ordina insulated Wires and must protect the shade from breakage due to the intense heat -of the heated-wires. v
Compactness and lightness are essential not only in order to facilitate the carrying thereof, but are necessary when it is deslrous of introducing the heater into an electric light socket carryingl a shade, the latter beingus'lally of limited size, and where the heater is suspended during its use without any support beneath it upon which it y.may rest.
As the heater is liable to sudden jars and the impactvof other articles when packed into a 'carrying receptacle, qit is essential that the .more delicate portions, as for instance"the resistant Wires, be protected in Order-'to revent dislocation and breakage.
If the eater is compact in form, it will within the usual.- glass, or porcelain, shade fand means must be emloyed whereby thefshadewill not be Abroken y the heat emanating om the heater.
Further, the heater must be easy of construction, economicalin cost and as free as possible from damage due to rough psaga vThe device of my invention accomplishes all of the above desirable results and overcomes the objectionable features of the present known heaters. In the particular form of my device shown in the accompanying drawings, simiylar parts areP designated by similan numerals.
Figure 1 is a vertical cross-section of one form of my device.
Fig. 2 is a cross-section through the line 2 2 of Fig. 1;
Fig. 3 is a cross-section through the line 3-3 of Fig. 1. y
Fig. 4 is a modified form of the lower portion of the shell of the device.
The particular form of my device,as illustrated comprises an exterior shell composed of the upper member 5 and thea lower member 6 attached thereto by the flange joint 7. The lower member 6 has a series of openings 8, 8 to allow of the exit of the heat from within the shell. The upper portion of the upper member 5 is carried by the electric non-conductor 9, having the exterior thread 10, capable of engagement with the interior thread 11 of the ordinary standard electric light'socket 12. The interior of the mem.- ber 5 is covered with asbestos 13. .The upper face of the member 9 carries the downwardly extended electric conductor plate 14,
poses described later. The plate 14 extends through the opening 14A of the member 9.
The device for carrying the heatin wires comprises a hollow porcelain member aving lextended arms 15, 15 upon the outer face of which isga spiralA recess 16. A downwardly extended electric conductor plate 17, having `a recess in its lower portion, is attached to the lower portion of which is bent for purholdably engage with the' recess of the plate 14.
The plate 20 is connected `by means of the wire 22 to the coiled resistance wire 23 which is placed within the recess 16 of the member 15, the coiled wire 23 'being extended into the wire 24 connected to the plate 21. An ordinar shade 26 is suspended by means of the sha e support 26A.
Fig. 4 illustrates a modified form of the lower shell of Fig. 1, comprising` a seriesof wires 27, 27 so arranged as to act as a protective guard for the interior of the device. This modified form of the lower shell can be ixedly attached to the upper shell, or movably attached thereto by the resilient action of the wires 27, 27.
It is evident that the shell 5 may be composed of a non conductor of heat instead of being covered- -by such non-conductor as shown; that the member 15 may be of suitable composition other than porcelain; that the arrangement of the. wire 23 may be different from that shown and the lower shell 6 may be of any suitable protective material and shape.
I do not limit myself to the particular size, shape, number or arrangement of parts as shown 'and described, all of which maybe varied without goingvbeyond the scope of my invention as described and claimed.
What I claim is 1. A portable electric heater comprising an upper non-heat conducting shell, an eX- terior thread upon the upper portion of the upper yshell capable of being threaded into an electric light socket, a lower foraminous shell capable of engagement with the upperl shell, a resistance wire within the chamber formed by the two shells and means whereby the insertion of the upper shell into a light socket will connect the resistance wire with the electric wires of`the light socket.
2. A portable electric heater comprising an upper imperforate non-heat conducting shell, an exterior thread upon the upper portion of the upper shell capable of being threaded into an electric light socket, a lower foraminous-shell capable of engagement with the upper shell, an`1nsulating carrying body within the chamber formed by the two shells,"-
a resistance wire carried by the carrying body, and means whereby the insertion of the upper shell into the light socket will connect the resistance wire with the electric wires. ofthe light socket'.
