murmur-mim Specification of Ilctters Patent.

Patented May 17, 19 21.

Application filed June 11, 1920. Serial No. 388,154.

To aZZ whom it may concern Be it known that I, EDWARD D. HISCOCK, a citizen of the United States, residing at Odell, in the county of Hood River and State of Oregon, have invented certain new and useful Improvements in a Carbureter- Heater, of which the following is a specification.

This invention relates to internal combustion engines and more particularly to vaporizers for use in connection therewith.

The object of the invention is to provide an attachment for application either to a carburetor or to the intake manifold of a gas engine to facilitate the starting of the explosive engine by supplying a highly explosive heated mixture.

Another obiiiect is to provide a simple and efficient attac mentof this character to insure the prompt starting of cold gas englnes, being constructed so as to provide suflicient heat to supply ample priming fluid to start a heavy engine when cold.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings. illustrative of the preferred embodiment of the invention.

In the accompanying drawings:

Figure 1 represents a perspective view of the attachment constituting this invention. Fig. 2 is a transverse section thereof.

In the embodiment illustrated the attachment comprises a substantially ovate casting 1 having a bore 2 extending longitudinally therethrough and provided at one end with an attaching pipe or coupling 3 while its opposed end is bent upwardly to form a receivlng cup 4. The coupling 3 may be of any desired construction and is designed for attachment to the air intake pipe of a carbureter or to be tapped into the intake manifold of a gas engine. The bore extending through thecasting is preferably somewhat larger than the discharge openings at the end thereof.

Arranged under and extending laterally beyond opposite sides of the body portion 1 of the attachment is a tray 5 secured to or cast integral with the casting and which is designed to contain gasolene or other inflammable fuel for heating the casting to v p ri e f el o be fed thro gh sa d castin It is of course understood that if thedevice is to be removably attached to the manifold and only used for starting a cold engine it will be necessary to provide a closure for the hole in the manifold which is made to receive the pipe 3. When the device is applied to the carburetor all that is necessary is to insert the gas discharge end 3 in the air intake pipe of said carbureter and hold the device in this position until the engine has been started.

In the use ofthis attachment the end 3 having been inserted in the manifold opening or the air intake of the carburetor gasolene is placed in the tray 5 and ignited which will thoroughly heat the casting 1. Fuel in the form of gasolene is then introduced through the receiving cup 4 and in its passage through the casting 1 will be thoroughly heated and vaporized before entering the carburetor or manifold. The cranking of the engine will operate to suck into the cylinders this heated vaporized fuel in addition to that supplied by the carbureter thus producing a highly explosive mixture which will insure qulck starting of the engine even in extremely cold weather.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claims may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

What I claim is:

1. An attachment of the class described comprising a hollow body having a discharge terminal at one end and an upturned receiving cup at its other end, and fuel containing means carried by said body and positioned to direct the heat issuing therefrom around said body.

2. An attachment of the class described comprising a hollow body having a discharge pipe at one end for connection with the air intake of a carbureter or with the manifold of an engine and equipped at its other end ith an upturned receiving cup,

said body having at its opposite sides near the bottom thereof a laterally extended fuel containing tray.

3. A device of the class described com- 5 prising a hollow body having an intake at one end and a discharge at the other, a fuel container carried thereby adjacentthe bottom thereof, and a handle connected with thetop for convenient manipulation of the device. 10

In testimony whereof, I aflix my signature hereto.

EDWARD D. HISCOCK.
