ELECTRICALLY-HEATED .SPRAY-VALVE.

'Application alsa March 13,1918.

Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Electrically-Heated Spray-Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as .will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to electrically heated needle spray valves, especially designed for use in connection with my steam auto- :mobile primary burner and main burner which form the subject matter 'of respective co-pending applications iiled March 25, 1918, and- February 26, 1918, Serial Numbers 224,599 and 219,284. v

-The main object of the invention is to provide means for electrically heating the hydrocarbon prior to its being ydischarged from the needle valve.

A further object ofthe invention is to provide the needle valve `with an electric heatingv coil positioned around the vspray I nozzle whereby the hydrocarbon may be heated and vaporized prior to its discharge fromthe nozzle.

A further object of the invention is to provide a second heating coil arranged in advance of the nozzle and in axial alinement-,therewith whereby the air surrounding the discharge end of the nozzle may be heated pri r to its admixture with the hydrocarbon (sis it is shot from the valve nozzle.

A still further object of the invention is to'arrange both heating coils in series so that the hydrocarbon will be heated and 40' heated air adjacent the discharge end. of

vaporlzed prior to its admixture with the the nozzle.

. l Astill further object of the invention is to provide-a simple and inexpensive needle 4 5 spray valve of the nature indicated which embodies a mimiinum number of parts.

With these and other objects in view as will appear as the description proceeds, the invention comprises the various novel features of construction, combination and arrangement of parts as will be more fully described hereinafter and afterward specilically claimed. f

valve.

struction of electrically heated needle spray I i Fig. 2 represents a vertical longitudinal I sectional view therethrough, and

Fig. 3 represents a sectional 4elevation of a modified form of valve.

In order that the construction and operation of the invention may be readily comprehended by those skilled yin the art to which the invention relates, I have illustrated an approved embodiment thereof in the accompanying drawings and will now proceed to describe the same in connection with said drawings, in which 1 is Jhevalve body provided at one end with a ange 2 and at one s1de with a laterallyl projecting threaded nipple- 3.v A circular-,shoulder 4 is formed on the end of `the valve body and carries a central longitudinally )disposed nozzle 5 having a reduced ortapered discharge end 6. The opposite end of the valve body is internally threaded for the reception-of one end of the plug '7, said plug being formednon-circular intermediate its ends as indicated at 8 for the application of a wrench, while the outer end 1s reduced to form-a neck 9 to which is threadedly connected a packing nut 10.

lA needle valve rod 11 is'dispo'sed -longitudinally through the nut\]\0, plug 7 valve body 1 and the nozzle 5, said valve rod becated at 12. r1`he .forward end of the .valve rod cooperates with the A tubular strainer 1 4 is removablypositioned within the valve body and plug and is supported thereby concentrically of the valve rod and serves to effectively arrest discharge orifice ing threaded through the plug 7 as indiany foreign matter that may enter the valve being discharged from the valve may .be

heated and vaporized, 1 position a suitable electric heating coil 15 around the nozzle 5 between the shoulder 4 and a disk 16 carried by the nozzle adjacent its outer end.

For desirable and additional heatinga coil 17 is positioned around the discharge end of the' nozzle and Vin axial alinement therewith andis connected in series with the heating coil 15. This additional heating coil will'e'ectively serve to heat'the surround- Y ng atmosphere prior to the admixturp of the hydrocarbon with it as it is shot from the nozzle, thus producing a combustible gas in'a more ready and 'efficient manner and at the same time4 tendingto eliminate theA hissing or roaring` sound commonA to needlespray valves. his result is due to the fact .that the electrical heating orre- A sistance Acoil .17 which surrounds the tip or discharge vend of the nozzle and which projects beyond said tip., has its convolutions spaced apart for the passage of air therecharged if* found desirable'.

through to the jet of vapor which discharges `from the nozzle. rIhus, the air in passing to the jet willbe heated'to attain thel desired results. l v I In the use of the valve the forward end lof the nozzle is projected throughl an opening in the burner .casing until the flange 2 rests flush against the outer surface of the burner casing. The. heating coils are connected in circuit with a batter l18 and a hand -operable switch 19 adapte to 'be positioned within convenient reach of the motor vehicle ydrivers seat whereby the-operator can 'at willinitially heat and vaporize the hydrocarbon 'prior to its being discharged into 4the 'burners in starting the machine.

In the modificationl shown in Fig. 3 the nozzle is provided with a ldetachable tip 20 embodiment thereof I desire to have it understood that such changes in construction and arrangement of parts may be made when desired as are within the scope of the ap ended claims. Vl

aving thus fully described my invention what I claim as new is: .y

1. A needle valve having l a shoulder formed at one end and a spray nozzle projecting centrally therefrom, a needle valve .disposed within said nozzle to control the discharge, an electric heating coil positioned -around said spray 'nozzle against said shoul- -der, a disk positioned at the outer end of said coil and mounted upon said nozzle, and an additional heating coil arranged beyond the discharge end of the spray nozzle and connected in series with the first named heating coil.

2. A .spray valve comprising a nozzle for the dischargeof fuel, an electrical heating coil on the nozz'le between its ends for heating the fuel therein, a'needle valvestem entering the nozzle from the rear end and controlling the flow `from the discharge end, and a second electrical heating coill surrounding the stream of fuel at the discharge end of the nozzle and having its convolutions spaced apart for the passage of air heethrough to the discharging'stream of v ue In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
