CARBURETER.

SPECIFICATION forming part of Letters Patent No. 768,732, dated August 30, 1904. Application filed November 18, 1903. Serial No. 181,109. (No model.)

To all whom it may concern:

Be it known that I, SELDoN CLARK BRUCE, a citizen of the United States, residing at the city of Goshen, county of Elkhart, and State of Indiana, have invented certain new and useful Improvements in Carbureters, 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 carbureter in which the introduction of the air and the liquid hydrocarbon in proper proportions is automatically controlled; second, to provide an improved carbureter in which the amount of carbureted air produced is controlled by the amount consumed; third, to provide an improved carbureter in which practically all of the liquid hydrocarbon is utilized; fourth, to provide an improved carbureter which although simple and compact in structure is of large capacity and is economical to produce and not likely to get out of repair.

Further objects and objects relating to struc- 2 5 tural details will definitely appear in the detailed description to follow.

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

0 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 drawing, forming a part of this speci- 3 5 fication, in which the figure is a side elevation view of my improved carbureter, a portion being shown in the vertical section to show the structural details thereof.

Referring to the drawing, A is the air-stor- 4 age tank,'and I is an air-pump and motor.

The pump is connected to the storage-tank A by a pipe I. The pipe I is provided with a suitable check-valve 2'. A delivery-pipe A is also provided with a valve a, located in front of the press u rc-regulator A, and a check-valve (6, located beyond the regulator. A reservoir B for the liquid hydrocarbon is provided. The

reservoir B is supported in an elevated position with reference to the carbureter proper 5 and is provided with an oil-delivery pipe 6.

A pipe I), which is connected to the air-delivery pipe A beyond the pressure-regulator thereof, opens into the storage-reservoir above the oil-level thereof. The object or this con? nection will appear later. A suitable valve b is provided for the pipe I). These parts are illustrated in conventional form.

The air-delivery pipe A and the oil-delivery pipe o open into a valve-chamber 0. Supported within this chamber on the pivoted le- 6 Ver 0 is a downwardly-opening lid-valve 0 for the air-delivery pipe. The valve 0 is adapted to be opened by the passage of air therethrough. The delivery of the oil from the reservoir B is controlled by the valve 0. The 0 5 valve 0 is provided with a downwardly-projecting stem adapted to rest on-the lever 0. Thus arranged the air-valve 0 opens downwardly and the oil-valve 0 opens upwardly, so that both valves are open at the same time. 7 The lever c" is suitably balanced, so that the valves are normally closed.

The carbureter consists of the chamber D and the vertical tube E, which is connected to the valve-chamber C and to the top of the 7-5 chamber D. The chamber D is provided with horizontally-arranged baflie-plates in the upper portions thereof. The baflEl'e-plates cl are oppositely arranged within the chamber D,

thereby forming a zigzag passage therethrough. A packing d, of suitable wicking or absorbent, is arranged between the bafHeplates. The tube E is provided with a plurality of foraminated partition-plates 0. These plates are concave in shape and are arranged 5 alternatelythat 'is, each alternate plate is arranged with its concave side up and the remaining plates are arranged with their concave side down. Thus arranged, the tendency is to spread the oil over the plates, which in- 9 sures a thorough contact of the air therewith. The service or delivery pipe F is provided with a pressure-regulator F. A- mercuryregulator f is preferably located beyond the regulator F as a further means of insuring a steady deliveryof the gas. A suitable checkvalve is provided for the service-pipe F. This check-valve is located in front of the regulator F.

The pressure-regulators A and F are set '1 t 15 aliJ at about the same point, so that when the pressure in the carburetor is relieved by draw ing gas from the service-pipe air is admitted. The incoming air opens the valve 0, and this through the connections described opens the oil-valve 0, so that the air and oil are admitted together. The valve 0 is so shaped that the amount of oil admitted therethrough is in proper proportion to the amount of air admitted. \V hen the pressure in the carbureter again reaches the predetermined point, the passage of air through the valve 0 ceases, and the valves are automatically closed, the pressure of the oil assisting in closing the same. In passing through the plates 6 the oil and air are thoroughly mixed. Should any surplus oil reach the chamber D, it is absorbed by the wickin g material (Z, and is thus brought in contact with the air passing therethrough. This insures a complete utilization of practically all the oil passing into the carbureter. A pressure equal to that in the carbureter is maintained in the oil-reservoir by means of the pipe 7/, so that the oil readily flows from the oil-reservoir into the carbureter by gravity. With the parts thus arranged the amount of oil admitted is properly proportioned to the amount of air admitted, and this is governed by the amount of carburcted air or gas drawn from the service-pipes.

My improved carbureter is simple and compact in structure, yet is of large capacity, is very economical to use, and is not likely to get out of repair. I have described and illustrated the same in the form preferred by me on account of its simplicity. 1 am, however, aware that it is capable of structural variation without departing from my invention.

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