T a/ZZ whom Lt may coaccrn:

Be it known that I, Jimrns A. KnNwonTI-rr, a citizen of the United States, residing at Oakland, in the county of Alaineda and .State of California, have invented new and useful linproveinents in Carbureters, of which the following is a specii'ication.

rl`he present invention relates to an improved apparatus for producing illuminating and fuel earbureted air from volatile oil, such as gasolene, distillate, and the like.

rl``he object of the invention is to produce an apparatus of this character which is comparatively cheap and simple in construction, which may be readily moved from place to place where needed, which will furnish a large amount of gas in proportion to its size, with which the care and attention required may be reduced to a minimum.

ln the aecompanying drawing, Figure 1 is a vertical section of my improved apparatus; lFig. Q is a detail view of the tripping niechanisin.

The apparatus comprises ay carbureter, in which the air is carbureled by forcing it through gasolene or other oil, which is also Constructed to form a receiver for storing the air thus earbureted, and a pump for obtaining the necessary air pressure for so forcing the air through the oil.

Referring to the drawing, 1 indicates the bottom of a carbureter casing upon which are erected inner and outer cylindrical walls 2, 3, forining an annular water chamber Al. is the cylindrical wall of a bell or receiver, depending into said annular space Lt and closed by a top 0. On the outer wall 3 are securer guide rods 7, and on the top of the bell are Secured guides 8 which can slide on said rods.

The space 0 within the inner wall 2 forms a carburcting chainber, and air is, by means to be presently described, supplied to said Chamber by a pipe 10, leading to a suitable height, centrally Tithin the earbureting Chamber 9, and discharging at the top into a tube 11 closed at the top and carried'by an annular float 12. rl`he air passing down on the outside of the pipe 10 and on the inside of the tube 11 escapes at the bottom of said tube 11 by a thin cylindrical Chamber 13 to upstanding pipes lil, each of which diseharges upwardly within the bottom of a, evlindrieal conduit Across each conduit are arranged a suitable number of transverse horizontal tine wire screens 10. The

purpose of these screens is to minutely divide the air, so that, in passing through the oil, it may be thoroughly impregnated with the oil vapor. The air thus passing through said sereens eventually becomes saturated with oil vapor, so that it rises to the top of the receiver completely carbureted. This carbureted air is withdrawn from the receiver by means of a pipe 17 leading` fromV a point above the water level to the gas main of the house or other place where it is to be used. From the bottom of the carbureting chamberapipe 18 leads to a glass gage 19 for indicating the level of the oil therein, a filling pipe 20 leading upward from the top of said gage and having a funnel 21 at the top, and a valve 22 therein.

F or the purpose of obtaining the necessary air pressure for forcing the air through the oil, I provide the apparatus shown on the leftiof Fig. 1, which comprises a base 27 upon which are erected inner and outer walls 28, 29, the space 30 between said walls being filled to a proper level with water. loto said space 30 depend inner and outer shells 31, 32, depending from aV top of an annular air bell or receiver 38. rl`he top of said air receiver is provided with guides 341 which slide upon guide rods Secured to the outer wall. The air enters said receiver at the top through a check valve 86 controlled by a spring 87, and discharges by means of a pipe 88 extending upward through the base to a height above the level of the water, the bottom of said pipe being` c nneeted by a pipe 89 through a check valve L10 with the pipe 10. lt will thus enter the pipe 10 by means'of said check valve L10, which immediately closes on again raising the air receiver.

ln order to avoid the neccssity of raising the air receiver by hand, I provide a Water cylinder 41 in which reciprocates a piston 42v having a piston rod 413, which moves through the upper head of the cylinder and has a head 441 abutting against the top of the air receiver. Surrounding the cylinder 41 at a short distance is a casing 45, spaced at the bottom from said cylinder to allow of the escape of air the upper head of the cylinder being also formed with air` vents 10, so th at as the piston rises, air can escape through said vents, then in the space between the cylinder fll and casing 415 and then outI at the bottom. lTo auton'iatically supply water to said cylinder to raise the hell., provide an inlet pipe 49 which leads to a three-way valve 48 connected with an outlet pipe 47, and also with a supply pipe 50 leading to the interior of the cylinder 41.

One of the guides 8 secured on the top of the receiver of the carbureter is extended to form a finger 51 and through said finger passes a rod 52. djustably Secured thereon is a stop 58, and said rod is attached to one end of atrip lever 54 pivoted on a suitable fulorum 55 upon a cross bar 56 supported at its ends upon vertical guide rods Secured to the sides of the outer wall 29 of the air receiver. The other end of said trip lever carries a weight 57 to balance the weight of the part upon the operating Side of the fulcrum. Extending from the side of the lever f-l is a plate 58, which, when the lever descends, is adapted to engage the nose 59 of a hook 60 pivoted at 61 upon the top of the receiver. Said hook is adapted, when the receiver is raised to pass over a Stud 69, extending from said cross bar 56 and is moved into engagement therewith by means of a spring 63 attached to said hook and to the top of the receiver. But, when said trip lever descends, said trip plate 58, engaging said nose, pushes it out of engagement with said stud 62, so that the receiver is free to fall, which it does, forcing the air into the oil receiver, and thus carbureting the air.

One of said guides 341: attached to the top of the air receiver is extended to form a finger 66, through which passes a movable vertical rod 67 having upper and lower f stops 68, 69, and when, in the descent of the air receiver, said finger strikes the lower stop 69, it causes said movable vertical rod to descend. The lower end of said rod is loosely connected, as shown at 70, to a lever 71, which is connected by a link 72 with a lever 73 attached to a three-way valve 48, having a balance weight 75. The result is, that, when the rod descends, said valve 48 is turned, to cause water to pass into the cylinder Lil from the pipe 49, raising the cylinder, and the air receiver. lVhen the latter arrives at a predetermined height, the finger 66 impinges against the upper stop 68, raises the rod 67 and thus turns the three-way valve, to allow the water to escape from the cylinder into the pipe 47, so that the air receiver can descend to force the air into the carbureting Chamber.

The object of supporting the screen-carrying conduits by means of a float is to insure uniformity in the thickness of the body of oil through which the air passes, thereby also insuring uniformity in' the degree to which the air is carbureted. lVith this object it is important that the fioat should be a sealed or closed float, in order that it may be of Constant buoyancy, so as to always fiow at a Constant depth. beneath the Surface of the oil. It is also important that the conduits which carry the screens should be open at their lower ends for the admission of oil independently of the admission of air. This is obtained by supporting the lower ends of the conduits by posts upon the float, and providing comparatively narrow air inletpipes lfl. These pipes, being of much less diameter than the carbureting conduits, produce the result that the force of the air completely eXpels the oil from the pipe and produces an upward movement of the oil around the pipe and through the open lower end of the conduit.

The reason for spacing the carbureting conduits from each other and from the wall of the carbureting chamber, is that, thereby, the air emerging from the conduits is compelled to flow through the oil above the upper ends of the conduits, and cannot escape by Iiowing upward in contact with the wall of the carbureting Chamber. In each ,arbureting conduit, the screens are arranged at a distance from each other considerably less than the diameter of the screens themselves. This arrangement renders it impossible for the air, after passing through a lower screen, to fiow to the next screen above along the inner surface of the wall of the conduit, and thus av'oid being carbureted.

I claim 1. In a carbureter, the combination of a carbureting chamber, means for supplying oil thereto, a completely closed hollow fioat, a carbureting conduit supported upon said float, a vertical series of screens arranged transversely across said conduit, and means for injecting air into the lower end of said conduit, substantially as described.
