CAHBURETER.

SPECIFICATION forming part of Letters Patent No. 779,906, dated January 10, 1905.

Application filed May 25, 1904. Serial No. 209,781.

To (LZZ whom it may concern.-

Be it known that I, HERBERT A. BURoH, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

This invention relates to improvements in carbureters.

The objects of this invention are, first, to provide an improved carburetor which is antomatic in its operation; second, to provide an improved carburetor in which the amount of carbureted air or gas produced is controlled by the amount consumed; third, to provide an improved carburetor by which two or more grades or qualities of carburetcd air or gas may be produced and delivered at the same time; fourth, to provide an improved carburoter in which low grades of refined hydrocarbon oils can be used with satisfactory results; fifth, to provide an improved carburetor by which all of the hydrocarbon oil is utilized; sixth, to provide an improved carburetor which, although simple and compact in structure, is of large capacity; seventh, to provide an improved carburetor which is simple in structure and economical to produce and one which is durable and not likely to get out of repair.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I- accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a detail side elevation view of a structure embodying the features of my invention. Fig. 2 is an end elevation view looking from the right of Fig. 1. Fig. 3 is an enlarged longitudinal sectional view through the carburetor tank or chamber, taken on a line corresponding to line 3 3 of Fig. 2. Fig.

4 is an enlarged transverse sectional view through the carbureting tank or chamber, taken on line i 4 of Fig. 3, showing the structural details of one of the drums D, the shaft C and gear thereof being shown in full lines. Fig. 5 is an enlarged detail transverse sectional view, taken on line 5 5 of Fig. 3, showing the arrangement-of the drums in the carbureting-chamber. Fig. 6 is an enlarged sectional View, taken on line6 6 of Fig. 4, showing the operating means for the oil-pump.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, A represents a rotary air-pump. This pump may be of any desired construction. On the shaft A of the pump A is a driver A" for the cable A', from which a suitable driving-weight (not here illustrated) is supported.

Supported on suitable brackets on the frame or casing of the air-pump A is a carburetor tank or chamber B. This tank, which is preferably rectangular in form, is arranged horizontally. In the bottom of the carburetingchamber B transverse oil-troughs b are arranged. These troughs are connected by a covered conduit Z), arranged along one side of the chamber. Supported above these troughs on the shaftsC are foraminated drums D. These drums are provided with coverings (Z, of fabric, preferably coarse linen. These drums D are supported in such position that their lower portions extend into the oil in the troughs 7) beneath, so that when they are revolved their fabric coverings are saturated with the oil. The drum coverings (Z extend practically across the carbureting-chamber. Supported on the ceiling of the carburetor-chamber above each of the drums D is a curtain or flap (2. These curtains are of such length that they lap overand rest upon the drums. These flaps are also of such width that they extend from side to side of the carbureting-chamber. The carburetor-chamber is by these drums and ourtains divided into compartments. In operation the curtains, resting upon the drums,

also become saturated with the oil, so that the air passing through the carbureter must pass through this saturated fabric.

The shafts C are supported in suitable ballbearings C. The bearings C for the inner ends of the shafts C are supported on the inner wall of the carbureter-chamber. The outer ends of the shafts C project through the walls of the carbureter, and the ball-bearings therefor are supported on the outside of the carbureter-wall. Suitable stufling-boxes, as C", are provided for the shafts C. The bearings C are protected from the oil by the inwardlyflaring hoods 7', supported on the walls of the carbureter, which project over the outwardlyflaring fianges on the hubs of the drums. The shafts C are provided with sprocketwheels 0. These sprockets are connected by a chain, by means of which they are driven. One of the shafts is provided with a sprocketwheel 0, which is connected, by means of a suitable chain, to the sprocket a on the shaft A of the air-pump, so that the drums are actuated whenever the air-pump is actuated.

The air from the pump is delivered to the carbureter-chamber by the pipe H, which is connected to the chamber at its forward end, as clearly appears in Figs. 1 and 3.

A suitable oil-storage tank, as G, is provided. The oil is delivered to the drumtroughs b by the pump F, which is connected by the delivery-pipe F to the last of the troughs b in the series. (See Figs. '1 and 4.) The oil-pump F is actuated by one of the sprocket-wheels c, which is provided with inwardly-projecting pins 0, which are adapted to engage the disk-like projection fon the pumprod F, (see Fig. 4,) so that the pump is actuated whenever the drums are actuated. A weight, as f, is provided to return the pump to its initial position. An overflow-pipe is provided for the drum-troughs Z). This is preferably connected with one of the intermediate troughs. Thus connected, the oil is maintained at a constant level in the troughs. A connecting-pipe r is provided for the oilreservoir and carbureting-cham her, so that the pressure therein is equalized.

Suitable closures B are provided for the carbureter-chamber, preferably one for each drum, so that the interior of the earbureter is readily accessible.

The carbureted air or gas is delivered by the service-pipes I I. The service-pipeI delivers the highest grade or richest gas and is intended to deliver gas for lighting purposes. This is connected to the carburetor-tank at its rear end, so that the carbureted air or gas delivered thereby must pass through all of the carbureting-drums. The service pipe I,

which is intended to deliver gas for heating or cooking purposes, is connected to the carbureting-tank at a point in front of the last carburetingdrum, so that the carbureted air or gas delivered thereby will be less rich in hydrocarbon than that delivered by the pipe I. The grade of the gas is further affected by the fact the fresh oil, which is of course most volatile, is delivered directly to the last trough in the carbureting-chamber. A further advantage of this arrangement is that the less volatile oil passes toward the forward end of the carbureting-chamber, where it is brought into contact with the uncharged air, by which it is more readily taken up. A greater quantity of oil is constantly being supplied than is used, so that some circulation is had in the troughs, the surplus returning to the receiver by the overflow-pipe. I thus secure an even grade of gas and am enabled to utilize all of the oil.

The inner ends of the supply-pipes I I are provided with a fabric covering 71:. This covering is preferably made of coarse linen, two or more thicknesses being used. This aids in securing an even quality of so-called drygas. The fabric covering 7'; is held in position by a ring b, which is slipped over the same onto the end of the pipe. The service-pipes I I are provided with pressure-regulators i i, respeetively.

The driving weight or motor for the pump is adapted to operate the pump against a certain pressure, so that whenever the pressure in the carburetor falls below a predetermined point the pump is actuated, which, through the connections described, actuates the carbureting-drums and the oil-pump. WVhen the pressure again reaches the predetermined point, the air-pump stops. An even quality of gas and con'iparatively even pressure are thus maintained.

While I have illustrated four of the carbureting-drums in the accompanying drawings, it is evident that the number may be increased or diminished as desired. I find four, however, to produce satisfactory results, and they may be arranged in a comparatively compact structure.

I have illustrated and described my improved carbureter in detail in the form preferred by me on account of its structural simplicity and economy, although I am aware that it is capable of very great structural variation without departing from my invention, and I desire to claim the same broadly as well as specifically, as illustrated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,
