VAPORIZING DEVICE.

Specification of Letters Patent.

Patented May 10, 1910.

To all whom it may concern:

Be it known that we, ABBoT A. Low, MAURICE J. WOHL, and HARRY Hnnrznnne, citizens of the United States, and residents, respectively, of Horseshoe, St. Lawrence county, State of New York, the city of New York, borough of Manhattan, county and State of New York, and of the city of New York, borou h of Brooklyn, county of Kings, and State New York, have invented certain new and useful Improvements in Vaporizin Devices, of which the following is a speci. cation.

This invention'relates to Vaporizers, applicable more particularly in connection with the carburetion of fuel for oil or kerosene engines.

t constitutes a development of the type of vaporizer in which the oil impinges or sprays upon a vaporizing surface heated by electrical resistance elements, preferably in the nature of bare wire coils, and the ob eots are to prevent loss of oil by spattering, to distribute the oil over the heating surface, to insure the retention of the oil upon the heating surface or in proximity to the elecmeans and instrumentalities for accomplishtrical resistance elements until complete vaporization is attained, and to provide an increased heating area.

The invention, therefore, consists in the ing these ends, as illustrated by this specification and the accompanying drawings and defined in the appended claims.

One phase of the invention may be said to consist in a vaporizing member in the form of a trough having its bottom and sides wound with electrical resistance wire, the sides serving to catch andvaporize any oil spattering up from the bottonn Another'phase of the invention relates to the provision of distributing grooves or channels formed in the vaporizing surface;

. and still another phase relates to the provision of a trap in communication with these channels, for receiving any oil that passes therefrom unvaporized and holding the same until vaporization is complete.

In the accompanying drawings, Figure 1 is a side view, mainly in vertical section, showing an embodiment or the invention, Fig. 2 is a plan-view of the vaporizing member, Fig. 3 is a transverse section therethrough, and Fig. 4 is alongitudinal section.

Referring now to these views, the numeral 1 indicates the vaporizing chamber, of which 2 is the air inlet, and 3 is the passage through which the oil is sprayed into the chamber and through which the explosive mixture is drawn from the chamber into the cylinder of the engine. The vaporizing member 4 may be mounted removably within the chamber 1 by being carried by the removable head and bottom member 5.

The vaporizing member i-may be said to be trough-shaped, possessing the bottom, preferably longitudinally inclined, member- 6, and the vertical, preferably triangular, side members 7. It is considered desirable to space the side members 7 from the lateral edges of the bottom member 6, to leave the spaces or slots 9; and this may be accomplished by "providing the member 6, conveniently toward its ends, with lateral lugs or projections 10, to which the members 7 may be secured, as by screws 11.

The members 6 and 7 are of insulating material (we have found slate a desirable material) and are wound, preferably transversely, with electrical resistance wire 12, which is preferably bare and may be half concealed in thecgrooves 13. 14 indicates a cable carryingthe terminals from the coils about the members 6 and 7.

The upper surface of the member 6 is preferably transversely arched, as shown in Fig. 3, and 'is provided with distributing channels or grooves 15. \Nhile these channels maybe variously disposed, we prefer to form them diagonally and intersecting. They are deeper than the wire-receiving grooves 13, and are therefore capable of carrying the oil impinged upon the surface of the member (3 freely over said surface and beneath the wires. These channels are shown following the curvature of the upper surface of the member 6, so as to deliver any unvaporized oil to the lateral marginal regions of the member 6. Here such unvaporized oil is received in a trap, d sirably in the form of a comparatively wide and deep channel 16, extending in U-shape around the lateral and lower marginal reg'ions of the upper surface of the member 6.

In operation, the oil that spatters up from the member 6 is-caught and vaporized by the side members 7 the channels 15 distribute the impinged oil over the surface of the member 6, thus hastenin vaporization; and the trap 16 receives and holds until vaporized such oil as might otherwise run off the member 6.

will be obvious that the particular form of construction illustrated need not be adhered to, and that the several features of the invention are susceptible to a considerable range of variation.

What we claim as new is:

1. A vaporizer for carburetion purposes, comprising a vaporizing'chamber, and avaporizing member therein consisting of a longitudinally inclined bottom wound transversely with resistance wire and upright side members similarly wound.

2. A vaporizing member for carburetion purposes, comprising a bottom section ro- .i ed with lateral projections, and upright side members spaced from the lateral edges of said bottom member by said projections, bottom section and side members being wound with electrical resistance Wire.

vaporizing member for carburetion purposes, comprising an insulating block traversed by electrical resistance wire, said block being provided in its upper surface with oil-distributing channels.

t. A vaporizingmember for carburetion purposes, comprising an insulating block provided with electrical resistance wire, the oil receiving surface of said block being travibting channels.

A vaporizing member for carburetion purposes, comprising an insulating block by electrical resistance wire, said .d with a network of intersecting oilblock being provided in its upper surface with oil-distributing channels and an oil trap with which said channels communicate.

(3. A vaporizing member for carburetion purposes, comprising an ins'ulatin block traversed by electrical resistance wire, said block being provided in its upper surface with a network of intersecting oil-distributing channels and an oil trap in the form of a comparatively wide and deep groove extending around the marginal regions of ,said surface and communicating with the ends of said channels.

7. A vaporizing member for carburetion purposes, comprising an insulating block traversed by electrical resistance wire, said block being provided in its upper surface with oil-distributing channels which conduct the oil beneath the wires.

8. A-vaporizing member for carburetion purposes, comprising an insulating block traversed by electrical resistance wire, said block having its upper surface arched and provided with oil-distributing channels and a marginal trap in the form of a comparatively wide and deep groove communicating with said channels.

Signed at Brooklyn, N. Y. city, in the county of Kings and State of New York, this 12th day of June, 1908.
