VAPORIZER.

Specification of Letters Patent.

atented Sept. 9', 1913.

Application filed March 24, 1913. Sera1Nof756,376.

To all whom it may concern.'

Be it known that I, GEORGE A. ARNOLD, of Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Vaporizers, oi? which the following is a specification, reference being had to the accompanying drawings, forming part thereof. Y

This invention has reference .to improvements in vaporizers and particularly to Vaporizers adapted to 4supply heat te 4air or other iuid Vpassing therethrough.

One object of the invention is to so censtruct a vapori/lier having a series of heat radiating units that air Aor other Huid in its passage through the `'vaporifzer ject'ed lto the `most :intense heat at or .about the initial point of suchpassage and thereaft-er be caused to circulate aboutvthe heating units of less intensity.

Another object of the, invention is to so construct a vaporizer of this nature Ithat a series ofheating units may be sustained by members mounted for removal with a wall of the vaporizer chamber and positioned thereby relative to the vaporizer iinlet.

Other objects of the invention Vwill apthe 'following description.

The invention consists in the novel construction and arrangement of the heat .radiating units.

The invention also consists in such other novel features of construction and conibination of parts as shall hereinafter be more 'fully described and pointed out in the claims. y

Figure 1, represents a longitudinal sectional view oi the improved vaporizer as taken on a line 1-1 Fig. 2. Fig. 2, -represents an end view of the vaporizer. Fig. 3, represents a crosslsectional view taken on line 3-3 Fig. 1 looking in the direction indicated by the arrows of'said line.

Similar el aracters of reference designate corresponding parts throughout.

Thisimproved vaporize: is particularly adapted to be attached to and form part of the air intake pipe or Hue of a carburetor for a combustion engine or to be applied as a conduit between the carbureter and the engine but, in its broad principle of application, this vaporizermay be utilized in any manner to supply heat to Huid passing therethrough.

shall be -sub- VThese ln Vthe simple embodiment ofthe invention of which the preferred form is shown in ythe vdraiif'ings 5 indicates the wall of the y vaporiaer chamber which, preferably,- is cylindrical in shape and is -supplied with the heat insulating -lining6, usually of asbestos. 7 and 8 are the .head `members of the vaporizer and are furnished with central openings vwhich are delined by clampingfcollars 9 and 10 adapted "to be clamped Aonto the ends of pipe members by the tightening ot their screws 11 and 12. The peripheriesot said vmember-s 7 and 8 have respectively the lips 1-3 and 14 which embrace the wall of chamber 5 and have- ears 15, 15 and 16, 16 through which extend screws 17, 17 and 18, 18 the inner ends of which are secured in perforations of the wall of'chamber 5.

Mounted in diametrically positioned openings of the head 8 are the bushings 19, 19 of hard rubber or of some other electrical insulation. Secured in-placein the bores of said bushings are the terminals 20, 20 preferably of copper and of comparatively large size. These terminals are bent inward, toward each other, and have the , members 21, 21 which are approximately fparallel. vision 'is made for limiting the movement of said terminals 20, 20 through the bushings 19, 19 by reducing the end portions of the terminals to form the shoulders22, 22 which bear against said bushings while the exterior end portions of said terminals are furnished with the wire-binding nuts 23, 23. Secured to the members 21, 21 of said terminals 20, 20 are the disk delectors 24, 25 and 26 which preferably are circular in shape and of different size, the disk defiector 24 being `pref-- erably smaller than the deflectors 25 and 26. delectors are of cast plaster or other suitable material adapted to resist heat and to form electric insulators whereby the heatresistancematerial and the length of wire in saidcoils differs, the length of wire in coil 27 being less'than that in coil 28 and thatin turn being of less length than that of coill29, so that the coils 27 and 28 are adapted to be ment or coil 27, the thus heated fluid raised to'a higher temperature than coil 29 l-bythe same amount of electric current. The

convolutions of the Wire of coils 27 and 28 have the interposed asbestos or other heat resisting material 30 and 31 while the conbe deflected by the delector 24 and will pass over and receive heat from its heating elewillv the vaporizer cham-v berV through the openingof its head 8. will expand and enter between defiectors 24 Vand 25 and will again be directed toward the wall of the chamber and will pass over the coil 27 and receiving heat therefrom will expand more readily; a likeopeation occurring as the expanded fluid is again deected by deector 26 with the addition that the expanded` fluid maycirculate between vand around the convolutions of the coil 29V which tends to maintain the temperature of the Huid andv distribute the heat more evenly therethrough.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

l; A vaporizer of the nature described comprising a cylindrical chamber,'a pair of clampin collars havin members removably mounteton' said cham er and forming the ends thereof, a pair of electric conductors carried by a member of one of said collars.4

Copies ofthis patent may be obtained for ve cents each, by addressing the electrical heating and forming vsupporting members within said chamber, a series of deflectors of electricl insulating material mounted on said conductors, and a series of electric resistance coils carried by said deiiectors, whereby said clampingA collar, conductors and deflectors form a removable unit. Y

A2. A vaporizer of the nature described comprising a cylindrical chamber, a. head secured to said chamber, a pair of electric terminals lextendingthrough said head, a series of deiiectors mounted on said terminals and increasing progressively in diameter, and electric resistance coils embracing said deflectors and in electrical connection with said terminals, one of said coils having its convolut-ions packed with heat resisting .material and another of said coils being open for the circulation of uid therebetween.

3. The combination with a cylindrical chamber, a head secured -to such chamber and having an inlet opening-and a clamping collar, a pair of electric terminals extending through said head, a deiector mounted on said terminals and in line with said inlet, an coil of comparatively high intensity mounted on said detlector and electrically connected pair of delectors minals at a distance from said first detlector and having electrical heating coils of progressively decreasing intenslty inv electric connection with said terminals substantially as described.
