VAPORIZER FOR EXPLOSlVE-ENGINES.

SPEGIFICATION forming part of Letters Patent No. 682,905, dated September 1*?, 1901. Application tiled May 20, 1901- Serial No. 61,047. (No model.)

To a/ZZ whom t petty concer-n:

Be it known that I, JOHN C. BLAND, Jr., a citizen of the United States, residing at Sewickley, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements in Vaporizers, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of this specification, in which f Figure 1 is a central vertical sectional view through my improved vaporizer. Fig. 2 is a horizont-al sectional view on the line II Il of Fig. 1. Fig. 3 is a sectional view on the line III III of Fig. 1. Fig. 4 is a similar sectional view on the line IV IV of Fig. 1. Figs. 5 and 6 are views similar to Fig. 1, but illustrating modified constructions.

My invention relates to devices for Vaporizing hydrocarbon and other liquid fuels; and

it consists in means for disintegrating and com mingling the liquid fluid with proper proportions of air in order to deliver the mixture to an explosive motor or other consuming device, and the invention relates to means for such purposes and also to means for regulating and controlling the supply of fluid and air, respectively.

Referring to the drawings, 2 represents the case, with which is incorporated the other elements of the invention, the case having at its upper portion an attached liquid-fluid-supply connection 3,0pening into the chamber 4, containing the needle-valve 5, by which the sup-l ply of iiuid may be accurately controlled. InV

the construction shown in Fig. 1 the seat- 6 for the valve is formed in the upper portion of a downward-extending hollow stem 7, which terminates in a conical hood 8, which hoodis surrounded byadownWardly-extended shell 9, formed integrally with or attached to the top 10 of the case. The case and likewise the shell are preferably circular in cross-section, and between the shell 9, which extends only partially into the interior of the case 2 and the sides of the case 2, is an intervening space 11, into which the commingled iuid and air will rise after emerging from the lower end of the point of which extends upwardly to the lower end of the hollow stem 7, and which is adapted toreceive the downward-dropping fluid,

which will spread out over the cone 12 in a thin covering of liquid upon the outer surface of the cone, from the lower edge of which it will drop upon the sides of a downwardly-extended dome 13, of fine wire-gauze, which projects downwardly to within the interior of the lower portion of the shell 2. The gauze may, however, be of other form or construction, as will be readily understood. The cone 12, hood 8, shell 9, and dome 13 are secured together in any suitable manner at the lower edge of the shell, so that their relation to each other ywill remain fixed, and as thus constructed it will be seen that there is provided between the inner surface of the cone' a narrow coniform space 14, so that the downwardly-dropping fluid may either flow upon the upper surface of the cone or upon the inner surface of the hood and in either case will be delivered at the lower peripheral eX- tremity of the shell 9, from whence it will fall into and upon the inner sides of the wiregauzedome 13. gauze covering dome-shaped it will be understood that any other form may be utilized which will give good results. Through the lower portion of the walls of the hood and of the cone are provided perforating-openings 15 16, preferably in register with each other, and in the upper portion of the top 10, Within the peripheryA of shell 9, are provided one or more air-inlet openings 17, through which air may enter, and such air will pass through openings 15 and 16 to the interior of dome 13, and in such action will take up or absorb a certain' portion of the liquid iluid, which as thus charged or' suspended in the air will be carried by it into the interior ot' the case 2 and from thence outwardly to the deliveryopening 18 to the motor or other point of-` consumption. For the purpose of more thoroughly commingling the air and fluid, eitherl or both openings 15 16 may be covered by In place of making the wirey thin gauze 19, as indicated, and it will be understood that these openings as well as their size may be regulated and adapted to the particular purposes in view.

Through the upper portion of the case 2 extends one or more perforated openings 2O for the purpose of admitting a diluting current of lair; For the purpose of accurately regulating ICO such supply any suitable cut-olf mechanism may be used, as a ring 21, provided with corresponding openings 22, which ring may be rotatably mounted upon the case, so that the supply of air may be accurately controlled or entirely shut o, as may be desired. At its lower portion the case 2 is provided with a drain-cock 23, by which any excess of fluid not taken up by the air may be drained away, and it will be observed that by the location of the outlet-opening 18 at the upper portion of the case the device as so arranged provides for the collection of any excessor unabsorbed liquid, and likewise insures the regularity of the mixture-supply to the motor.

In the construction shown in Fig. 5 the hood Sis dispensed with, the valve-seat 6 being merely screwed up into the top 10 and valve-case 4, while a cone 12 is alone mounted in the interior of the shell 9 and is adapted to receive the downward-dropping liquid and to spread it out in a thin film and to discharge it upon the interior of the gauze dome 13.

The `,frauze-covered openings 16 are also provided, and the case is in every respect the same, the operation of the absorption by the incoming air and the circulation of the miX- v ture being substantially the same as already described. Ihave, however, provided ashort tube 7 to insure the accurate dropping of the liquid upon the point of' the cone.

In the construction shown in Fig. 6 the cone 12 is dispensed with and the hood 8 retained,

the liquid in such case dropping downwardlyl upon the interior walls of the hood, spreading out thereon in a thin film, and being discharged upon the inner side of the gauze dome. The openings 15 may likewise be covered with gauze, as shown, a-nd the construction of the device otherwise as well as its operation, the circulation of the incoming and outgoing currents of air and mixture being the same as I have already described.

I am aware that perforated cones have been employed in devices for the general purpose of vaporizing liquid uids, and am familiar with the patent issued to B. W. Grist, No.

545,125, but believe I am the first to make a vaporizer in the manner shown and described.

The advantages of my invention will be readily appreciated by those familiar with the use of fluid motors or those utilizing liq" nid fluid in any case where it is desirable to finely commingle and charge the same in an air-supply. It is very simple in construction,

economical, and not liable to get out of orshown, but to include all such changes and i variations within the scope of the following claims.
