IMPROVED APPARATUS FOR GASIFYING AND BURNING CARBON OILS.

To all whom. ill/may concern:

Be it known that I, OsoAR F. MORRILL, a citizen of the United States of America, and a resident of Chelsea, in t-he county of Suffolk and State of Massachusetts, have made a new and useful invention having reference to Aerovapor Burners or Apparatus for Generating and Burning with Air the Vapor of a Liquid Hydrocarbon; and I do hereby declare the same toA be fully described in the following specification, and illustrated in the accompanying drawings, of which- Figure l denotes a longitudinal section of an apparatus containing my invention. Fig. 2 is an under side view of its screw-cap.

The principal parts of an aerovapor-burner to which my invention is applicable are the fluid-reservoir A, the vapor-generator B, the air and vapor mixing chamber C, the vaporconduit D, and the perforated or foraininous diaphragm E. In the operation of these the liquid is drawn up by a wick, F, and passes irom thence into the generator B, which is a hollow arm extended over the foraiuinous diaphragm E. Out of the said arm a pipe, D, passes and descends and opens into the air and vapor mixing vessel C, which is open at bottom or at its sides, so that air may enter it and mix with the vapor and pass up through the meshes or holes of the part E and be burned on the latter. The ame ofthe combustion of the mixed air and hydrocarbon vapor will heat the arm B and vaporize the liquid which may be therein.

The nature of my present improvements consists as follows: first, in arranging the receivingmouth of the tube D above the lower part of the inner surface ofthe arm or vaporgenerator B, the saine being in order to prevent the fluid in a liquid state from being driven from the generator into the pipe D; second, in extending the tube D forward into the vaporizer and over the diaphragm E, in order not only that theheating of the liquid and vapor may be facilitated and the vaporizer be prevented from being fused or melted by the iiame, but the tension of the vapor be brought to an extent highly favorable for its discharge into and through the mixer or burner; third, in constructing the screw-cap with an annular recess, (to receive the outer edge of the washer,) in combination with a core or projection arranged therewith,substan tially as hereinafter shown and described, the object of the Said recess and core being to facilitate the retention of the washery in place within the screw-cap during as well as after removal of the lat-ter from its screw.

The receiving-mouth of the tube Dis shown in Fig. l, at c, as elevated off and above the bottom surface, b, o f the interior space of the vapor-generator B. rIhe conduit D is also represented as constructed with a part, c, of it bent horizontally and extended forward of itsjunction with the said vaporizer or genen ator and into that part of the generator which is immediately over the diaphragm E. i

The screw-cap G of the reservoir A is also shown in the figures as provided with an annular washer, H, arranged and so as to [it upon and surround a projection, d, extended from the under surface of the flat part of the cap. The external edge of the washer extends into a groove, e, which is formed around in the inner surface of the screw cap and just above its female screw.

I have found that coal-oil, naphtha,and various other hydrocarbons have thc effect of shrinking the washer, so as to render it liable y to be easily displaced from its seat or position in the cap. The projection d will not only operate to prevent much of such shrinkage, but in consequence of the latter will serve to retain the washer in place. The annular groove e will also operate to prevent the washer from being displaced.

I claiml. The arrangement of the receiving-mouth of the conduit D above the lower part of the interior of the vaporizer, as described.

2. The extension of the conduit D, as set forth, into the vaporizer B and across and over the burner or part E thereof, substantially as and for the purpose set forth.

3. The screw-cap G, as constructed with the central core or projection, d, and the annular recess e, arranged within it and to receive the washer when placed within the screw of the cap, as set forth.

OSCAR F. MORRILL.
