VAPORIZING DEVICE.

Specification 01 Letters Patent. Patentpd Sept, 13 191() Application filed June 16, 1908. Serial No. 438.787.

To all whom it may concern:

Be it known that we, Anno'r A. Low, Maurice J. form, and HARRY Hcn'rzmnui, citizens of the United States, and residents, respectively, of Horeshoe, St. Iaiwrence county, State of New York, the city of i\ew Ylork, borough of h'lanhattan, county and State of New York, and of the city of New York, borough of Brooklyn, county oi. Kings, and State of New York, have invented certain new and useful I mprovements in vaporizing Devices, of which the following is a specification.

This invention relates to vaporizers or heaters and particularly to a vaporizer adapted for use with an internal combustion engine.

The object of this invention is to provide a simple and etlicient device of the character mentioned for use with engines of this type. It will also be evident that the invention is not limited in its application to the specific use herein set outand described but ma}, be adapted and arranged for heating fluids and for many other purposes which will suggest themselves.

For the purpose of illustrating this invention a coil of wire which is adapted to be heated by electric current passing therethrough is mounted upon a suitable support. This support is provided with a corrugated surface and is mounted in the vaporizing chamber of the engine so that the entering stream of fluid strikes the same and is spread over the surface thereof in contact with the heated coil. This arrangement causes the liuid to be quickly and uniformly 'aporized after which the same is mixed with a suitable amount of air to form the explosive mixture which is then supplied to the cylinder.

In the drawings like parts have been given the same reference numbers.

Figure 1 is a side elevation, partially in section. of a portion of an engine. Fig. 2 is a detail view of the heating coil. Fig. 3 is a detail view in section of a portion of the heating coil.

.-\n engine cylinder is shown at 1 and at 2 is shown the chamber inclosing the valves which control the admission of the explosive mixture.

At 3 is indicated the inlet pipe through which the fluid forming the explosive mixture is admitted and directed in a stream or spray into the vaporizing chamber 4.

vaporizing coil 5 is positioned upon the support 6 in the vaporizing chamber 4 and extends diagonally across said chamher as shown in Fig. 1. The purpose of arranging this vaporizing coil is that the entering stream of fluid from the supply pipe 3 will strike this coil and spread over the same and gradually run down over the inclined surface over the successive turns of the coil and thus become entirely vaporized.

Current for heating the coil is supplied from the line 7 which may be connected to any suitable source of supply. The head of the vaporizing chamber 8 may conveniently form an attachment or support for the coil support ('3 and an inwardly extending projection therefrom, such as 9, may form the support for the opposite end. This arrangement also provides an easy means of removing the vaporizing coil from the chamber for cleaning, replacing, etc.

After the fluid has been vaporized as above described the same is mixed with air from the supply pipe 10 and is drawn into the cylinder 1 through the regulation inlet valves.

The support (3 is formed with a corrugated surface, in which corrugation the turns of the coil 5 are placed. To accommodate these turns of the coils the corrugations may be spiral in form and it has been found that a coil so constructed gives very el'licient results in vaporizing the fluid. Such a construction is shown in detail in Figs. 2 and 3.

The details of construction herein shown and described are intended as an illustration of one embodiment of the invention and the appended claims are intended to include all such modifications as may be necessary to adapt the same to various other engine constructums.

What we claim is:

1. in an explosive. engine, a vaporizing chamber. a vaporizing coil having a flat side positioned in said vaporizing chamber. the plane of said flat side being inclined to the direction in which the lluid is injected,

means for injecting the fluid to be vaporized into said chamber and against'the flat side of said coil, and means for heating said coil.

2. In an explosive engine, a vaporizing chamber, a coil support having a flat side positioned in said vaporizing chamber, the plane of said flatside beinginclined to the directionin which the fluid is injected, a vaporizing coil positioned on said support with the turns traversing said flat side transversely to the direction of inclination thereof, means for injecting the fluid to be vaporized into said chamber and against the flat side of said support and coil, and neans for heating said coil.

3. In an explosive engine, a vaporizing chamber, a. vaporizer compr sing a flat supasses port positioned diagonally in the vaporizing chamber, a heating coil positioned on said support with the turns prO ectmg above the surface thereof in such a manner that the incoming stream of fluid to be vaporized flows successively over the turns of the coil, and means for passing a current through said coil forheating the same. Signed at Brooklyn, N. Y. city, in the county of Kings and State of New York, this 2nd day of June, 1908.-
