JAMES J'. CONNORS, 0F JUNEAU, TERRITORY OF ALASKA.

HEATER.

To all whom it may concern:

Be it known that I, James J. CoNNoRs, a citizen of the United States, residing at Juneau, in the Territory of Alaska, have invented new and useful Improvements in Heaters, of which the following is a specification.

This invention contemplates the provision of a gasoline heater and vaporizer, designed for association with the intake manifold of an engine. and arranged to heat and vaporize the gasoline just prior to its admittance into the firing chamber to facilitate starting of the motor in cold weather.

The invention contemplates the provision of a device of this character which is very simple in construction, and designed to permit of its association with the intake manifold of any construction.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application. like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a view of an intake manifold showing the location of the heater and vaporizer thereon.

Figure 2 is an enlarged longitudinal sectional view through. the device forming the subject matter of the present invention.

Figure 3 is a top plan view.

Figure 4 is a detail view of the bushing showing the electrode and heating element associated therewith.

Figure 5 is a view in elevation of the complete device.

Figure 6 is a bottom plan view.

The combined heater and vaporizer forming the subject matter of the present inven tion comprises a shell 10 which is smooth for a portion of its length as at 11. and threaded for the remaining portion of its length as at 12. The smooth portion is provided with perforations 13 and this portion is adapted to be arranged in the intake manifold projecting therein through an opening formed in the manifold for this Application filed March 10, 1923.

purpose. It is of course to be understood. that the shell is threaded in this opening by means of the threads 12. Threaded into the shell is a bushing 13 which is provided with a core 14 of mica or other insulated material, the core being spaced from the shell as shown. Passed through the bushing and core is an electrode 1 1, one end of which is attached to the adjacent end of a heating coil which surrounds the core and spaced between the latter and the perforations of the shell. A nut 15 is threaded on the inner end of the electrode and is utilized for holding the heating element 16 associated therewith. The opposite end of the heating element bears against the bushing. The electrode is energized by a suitable wire 17 leading from the battery or other source of current for the spark plug for the motor, and is controlled by a suitable switch. not shown, arranged within convenient reach of the operator of the vehicle.

In practice, when the device is used, the gasoline as it passes the perforated portion of the shell and brought in contact with the heater, is heated and vaporized just prior 7 to its admittance to the combustion chamber which of course materially facilitates starting of the motor especially in cold Weather, and is particularly useful in saving the battery, which is subjected to great strain and wear during cold weather when called upon and used during the starting of the motor. the device is very simple in construction and can be manufactured and sold at a nominal cost and furthermore it can be usel in conjunction with any type of manifol While it is believed from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, 1 claim:

A gasoline heater and vaporizer for intake manifolds comprising a shell having a smooth portion and a threaded portion, and adapted to be threaded into an opening in said manifold, a core of insulating material arranged within the shell and spaced therefrom, an annular shoulder arranged centrally of the core, and an electrode passed longitudinally through the :core, a; heating wire having one end looped about the core and reposingupon said shoulder, said-heating element beingwoundabout-the core bee neath said shoulder and having its other end secured to said electrode, a bushing threaded into said shell and impinging the looped end of saidheating element against JAMES J.
