The vheating-.element'includes e casing threaded .intoen opening provided-in the carburetor while. the inner end of the casing has ccnl v nected-` theretoV 'a -metallic tubing preferably of malleable material vso that the same may .togjntiniately the bottom walboftheliirburter. resisance wire is arranged .wit inxt ie` tu ing an supports n. luralityofantifriction members, 1 as agate s swhercb the wire is held spacedfrom t e-tubing nt all times The resistance wireleads to the switch plate which.is.. in 4communication with a'storage battery or dry cells of thenutomobile. -.Referringmore in detail to the accoma :my ingdrswin the reference numeral esignntes een ureter including-aiA float 11 nndh'zxving a. threaded plugV 12 -attachd thereto bylwhch the seme to the manifold of afgas engine. As shown in Fig. 1 1. the bottom of the carburetor 10 is` prodraining thebowl of the carburetor. The l improved ,form of heating' device assoeiated with the carburetor' l0 is, more clearly shownin Figs, 2te 5-'nnd includes a casin 1 4' having y .witha luternl opening 16 arranged; adjacent the closed end,7thel,casing 14 having-nn annular Bange-.17 arranged djucent t e opening-1Q .whilefthe portion ofthe-casing opposite the liane 17i is screw-threaded as :it 1 8 .for threade engagement with an opening provided in the lower end of the carbureter 10. When so positioned, the threaded end of the casing 11i rojects'outwnrdly of the carbureter 1031s lown in Fig. 2 und is adapted for the reception of n lock nut l.7" whereby the same may be locked in position, it being Patented June 19, 1917.

onej'end closed. hsat 15 les washers 17" may be positioned between the fiange 17, nut 17* and the wall of the carT bureter. The threaded end of the casing 14 vided therein register with similar grooves 22 provided in the outer end of the casing 14, and within which registering ooves are positioned retaining elements, as' e s 23. A metallic terminal plugY 24 is forci ly positioged within the bore of the insulator bushingI 19, and as shown in Fig. 2, the terminal plug and insulator bushing are' provided with coperating shoulders which will limit the inward movement of the plug.- 'As shown, the plug is of such length as to permit the inner end thereof projecting beyond the inner-.fend of the bushingfor purposes of attaching the resistance wire thereto.'

Thel inner projecting end of theplug 24 is provided with a terminal opening 25 comi.

municating with the transverse bore 26' and the resistance 'wire 27 has one end thereof introduced into the terminal bore 25 and laterally directed into the?, ransverse bore 26 and retained in such posi ionV by the fastening pin 28. The resistance .wlre 27 is arranged within a'metaltubing. 29 which has one-end extended into the. opening 16 provided in the casing 14 while the other end of the tubing 29'is -closed as by4 a metallic plug 30. The outer end of the resistance wire 27 is passed through an opening) provided in the plug` 30 and-is adapted to eengaged by a wedge pin 31 for retaining the` same in position. As shown in Fig. 2, the resistance wire 27 supports av luralityof beads 32 which may be of any now'n noxiconducting` material as agate, which will hold the resistance-wire spaced from the tubing 29 to reduce friction and Wear on the wire as well as damage whichv mi ht` be caused by short 'circuiting The tubing, 29

as'shown in Fig. 2, has been twisted at right angles from its operative 4position for purposes of illustration and it is to be assumed that the tube is in the z position 'shownin Fig. 1 when operatively arranged.

The outer projectin -end of the terminal plug 24 has a thread@ extension 33 adapted for the reception of'authumb nut 34 for.

clamping the metallic wire holder 35 thereto, the wire holder 35 carrying the wrapped -Wire 36 which extends to the rear of and is suitably connected to the switch plate 37 upon the instrument board 38 of an automobile. As shown in Fig. 1, the switch late is provided with a hand switch 39, a lig t bulb 40 and a push button 41. When the switch 39 is turned to close a circuit, one-half of the source of electricity is thrown in circuit with the Vresistance wire 27, and simultaneously with the closing of the circuit, the light bulb 40 is illuminated to'A indicate that the device is properly circuiting. The current passes from the wire 27 to the plug' 30 and tube 29 which'is in intimate contact with the carbureter 10 for heating the contents thereof, as will be plainly obvious. It is to be understood that in extremely cold weather, the switch 39 may be left turned on -I ent and while the form'of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is neverthele' to' be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirlt and scope of the invention as claimed.

6. A heater for crbureters comprising a casing, :in insulator bushing therein, u. plug within the bushing, a tubing carried. by the casing and closed at one end, a resstence wire within the tube and connected to' the closed end thereof and to -sad plug, and means carried by the wirey to hold the 'same spaced from the tubing.

7. A heater comprising a. casing, an insulator bushing therein, a plug within the bushing, a tube carried by the casing, a, re

sistnnce wire extending through the tube and connected at one end to said plug, a, closure plug for the open end of the tube having :1n opening therein for the reception of the resistnce wire, and means received in said opening for retaining the resistance Wire -in position.

8. A heater comprising u, casing, an insulator bushin therein, a plug within the bushing, u tu e carried by the casing, a resistance wire extending through the tube and connected. at one end to said plug, e closure plug for the open end of the tube 'havlng an opening therein for'the reception of 'the resistance wire, and u Wedge-pin received in seid opening to engage the end of the resistance wire frictionally to li'old the sume in position.
