MANIFOLD-HEATER.

Specification of Letters Patent.

Patented Nov. 16, 1920.

To all whom it may concern Be it known that we, HARRY D. WORK- MAN and l/VILLIAM S. SMITH, citizens of the United States, residing at Tishomingo, in the county of Johnston and State of Oklahoma, have invented certain new and useful Improvements in Manifold-Heaters, of which the following is a specification.

This invention relates to a manifold heater for internal combustion engines, and an object of the invention is to provide a device for heating the intake manifold of an internal combustion engine to facilitate the vaporizing of the combustible fuel being fed into the cylinders of the engine, so as to permit the engine to be started in all kinds of Weather, as well as to cause quick and thorough vaporization of the fuel resulting in the obtaining of the maximum power therefrom.

Another object of the invention is to pro vide a manifold heater as specified which heater comprises a pipe section adapted to be clamped in engagement'with a manifold to the lower end of which section a lamp structure is detachably connected, the said lamp structure having communication with the interior of the pipe section, so that the heat generated by the flame in the lamp will heat the manifold of an internal combustion engine. A further object of the invention is to provide means for igniting the wick in the lamp structure, which means may be controlled from the. instrument board of an ordinary motor vehicle, and which comprises a pivoted lever carrying a Dyrophoric wheel which is drawn over asparking member, to ignite the wick, and to connect the lever which carries the pyrophoric wheel to a lid or cover of the lamp structure, which will, when the control is released fall and close the upper outlet of the lamp, snutfing out the flame on the wick, while when the cover is raised by operation of the control, the pyrophoric wheel will be moved over the washer, to-ignite the wick.

Other objects of the invention will appear in the following detailed description taken in connection with theaccompanying draw: ings forming a part of this specification and in which drawings: v

Figure l is a view illustrating the improved manifold heater applied to the en. gine of an automobile.

Fig. 2is a side elevation partly in section of the manifold heater or fuel vaporizer.

Fig. 3 is an end elevation of the heater.

Fig. 4 is a side elevation of the heater looking at the inner side thereof.

Fig. 5 is a detail section through the instrument board of a vehicle showing the control for the lamp locked in position to hold the cover of the lamp open.

Fig. 6 is a view similar to Fig. 5 illustrating the control in the position assumed when the cover of the lamp is closed and the'latter is inoperative.

F ig. 7 is a cross section on the line 77 of Fig. .1, and

Fig. 8 is a section on the line 88 of Fig. 4.

Referring more particularly to the drawings, wherein like characters indicate like and corresponding partsv throughout the several views, A indicates a motor vehicle of any approved type having the usual motor or internal combustion engine B therein and instrument board C. The improved manifold heater 10 is attached to the intake manifold D of the engine B and is provided for heating the fuel delivered into the cylinders of the engine from the carbu'reter through the intake manifold D.

The improved manifold heater 10 comprises a substantially T-shaped pipe or conductor 11, the cross head or portion of which, is substantially semi-cylindrical in shape, being opened at its fiat side, and provided with spaced flanges 12, which engage the outer surface of the manifold D as clearly shown in Figs. 3 and 7 of the drawings. The stem or depending portion of the T-shaped pipe 10 is also cut away for a portion of, its length as shown at 14, provided with flanges 15,similar to the flanges I2 for engaging against part of the depending portions of the intake manifold D. The stem 13 is bent outwardly, below the cutaway portion as clearly shown in Fig. 3 and is flattened to assume substantially a rectangular shape, having its lower end open. A pair of spring catches 16 are carried by the rectangular portion 17 of the T-pipe 10 and they are provided for engagement over lugs 18 formed upon the sides or edges of'a lamp housing 19. This lamp housing 19 is ectangularshaped in cross section and fits into the lower 0 en end of the rectangular portion 17. The lamp structure 19 includes a wick 20 which passes upwardly to a partition 21 in the lamp housing and is arranged so that flame from the wick will pass upwardly into the pipe 10 for heating the manifold D. The portion of the housing 19 below the partition 20 is filled with any desired fuel, through a suitable filler opening 22. The wick 20 is ignited, by means of an igniter structure comprising an articulated arm 23 carrying a wheel 24 of suitable pyrophoric material upon its free end, which is adapted for engagement with an abrader 25 to cause sparks to ignite the wick and fuel therein. The abrader 25 is yieldably held by means of a spring in engagement with the periphery of the wheel 24.

The articulated arm 23 is pivotally connected to a cover 26 on the upper end of the lamp housing 19 and when this cover which is hingedly connected to the housing 19 is lowered it will smother the flame of the wick, putting it out. However, when the cover 26 is raised or moved into an open position it will move the wheel 24 over the abrader 25 to cause a spark for igniting the wick 20. The stem 13 is provided with a plurality of vent openings 27 to permit the supplying of the necessary air to the interior of the stem and the lamp housing to allow the fuel in the wick to burn.

A wire 28 is connected to the cover 26, and extends through a suitable protector 29 of the flexible shaft type, to the instrument board C of the motor vehicle, and it extends through a slot 30 in the said instrument board, having its end remote from the cover 26 attached to a suitable button 31. The button 31 is provided with a recess 32 therein, which is adapted to receive the angled end 33 of a spring lock member 34:, to hold the button in an extended position relative to the instrument board 0, and when in such position to hold the cover 26 open to allow the lamp to burn, to heat the manifold D. Then the button 31 is moved inwardly toward the instrument board C, the cover 26 will be closed, for putting out the lamp. The slot 30 will permit oscillatory movement of the button 31, to move it sufliciently to disengage the angled end 33 from the re cess or notch 32. The T-shaped pipe ofthe heater is clamped to the manifold D by split ring clamps 35 and the edges of the flanges 12 and 15 bind against the manifold for preventing to a material extent the escape of the heated air from within the pipe section 10, resulting in the air which is heated by the lamp structure 19 heating the manifold D and through the manifold l.) heating the fuel fel l into the cylinders of the engine B, to facilitate the vaporizing thereof so as to permit the fuel to be readily exploded within the cylinder regardless of weather conditions and also to permit more thorough vaporizing of the fuel and conse- "P P stantially semi-circular and havlng its fiat quent obtaining of the maximum power efficiency therefrom.
