FUEL ECONOMIZER Application filed August 21,
This invention relates generally to fuel economizers for use in reducing the 0011- sumption of gaseous volatile fuels, and particularly to a fuel economizer for incorporation in an automobile carbureter for reducing the consumption of gasolene and permitting more eflicient combustion of the fuel in the motor, insuring greater gas mileage and better running of the motor.
It is an object of this invention to provide a simple and inexpensive economizer of the type described, which is highly eflicient, is
durable and satisfactory in operation.
It is also an object of this invention to i produce an economizer of the type described which functions to considerably reduce the consumption of fuel in an automobile engine and which produces smoother and more powerful functioning of the motor.
2:": It is also an object of this invention to produce a highly efficient economizer of the type described which is composed of few and simple parts, is readily and inexpensively and easily installed in a standard cart' bureter, and which is simple and easy and inexpensive to manufacture.
These and other objects of the invention, its nature, its composition and arrangement and combination of parts, will be readily 13 understood by anyone acquainted with the art to which this invention relates upon reading the following descriptions of the drawings, in which:
Figure 1 is a longitudinal vertical partial sectional view of a carburetor showing the parts and the arrangement thereof according to my invention.
Figure 2 is a top view of a carbureter showing installed therein my improved economizer.
Figure 3 is a bottom view of Figure 2.
Figure 4 is an enlarged detail of my improved economizer attachment partially in vertical central section.
Figure 5 is a transverse horizontal section looking downwardly on the line 5-5 of Figure 4.
Figure 6 is a similar view on the line 66 of Figure 4:.
It is to be understood that I do not desire 1930. Serial No. 4%,848.
to limit the application of this invention to the particular modification set forth'herein, to illustrate the principles thereof, and any change or changes may bemade consistent with the spirit and scope of the invention.
Referring in detail to the drawings, a conventional carbureter is generally designated by the numeral v5, and it is provided with a mixing chamber 6 having the lateral opening 7 which is adapted to be closed by the butterfly valve 8, and the upper opening 9 which is adapted to be connected with the manifold. The numerals 22 and 23 refer to valve and throttle control means of conventional type. v
The main fueljet of the carbureter is indicated at 10 and the auxiliary idling jet by the numeral 11. My improved fuel economizer consists of a tube 12 the lower end of which is placed through the lower Wall 130f the car- 'bureter so that it communicates with the out side air. From the point 13 the tube rises for a short distance then bends laterally'and upwardly into the mixing chamber proper, and then is sharply directed upward to project near the top of the opening 9, where it is formed with an annular depression 14, and a plate 15 closes the top of the tube.
In the upper portion of the tube below the annular depression 14 there is provided a plurality of holes 16 which serve to give turbulence to the charge of air within the tube.
At the bottom of the annular depression 14 there is provided a plurality of holes 17 which permit the discharge of the volatilized fuel upwardly into the manifold.
The central portion of the plate 15 at the upper end of the tube is apertured and screw-. threaded to receive a pointed adjusting screw U 18 which is adapted to be lockedin projection into the tube by a lock nut 19. The tube 12 is so positioned that it will have the screw 18 exactly over the aperture 20 in the main fuel jet 10 when the tube 12 is superposed upon the jet 10, an aperture 21 in the tube 12 being w provided to admit the upper end of the gas jet 10 into its interior and to a height some what above the holes 1 in the wall of the tube 12. V
The screw 18 is adapted to spread the m0 fuel coming through the passage 20 in the main fuel jet 10 and the screw 18 is also adapted to be adjusted to co-operate with the end of the fuel jet 10 to control the admission of fuel into the tube; The narrow portion of the tube formed by the depression 14 is intended to produce a more thorough mixing of the air and fuel within the tube 12.
The controls 28, 23 of the carbureter are in no way disturbed except to readjust the same as required by the rate of operation of the motor after the installation of my im proved fuel economizer. It is thought to be obvious that the drawings and description disclose the fact that air is admitted at the aperture 13 in the lower wall of the carbureter into the tube 12 and travels in the direction of the arrows. The air collides with and mixes with the fuel coming through the main fuel et 10 where it is mixed at the point of the annular depression forming the restricted area at-the upper part of the tube 12 I where it is diffused and discharged through ghe holes 17 upwardly into the engine mani- 01d; I 3 It is thought to be obvious that I have provided a simple, efficient and durable device of the character described which is simple and easy to install and simple and inexpensive to manufacture. i It isthought to be also obvious that I have provided a device of the character described which possesses features of novelty which render it highly efficient and admirably adapted for the purposes for which it was designed.
Iclairn-z 1. A fuel economizer for a carbureter having a fuel and air mixing chamber, a main fuel jet and a mixed fuel discharge in the chamber, comprising, a curved tube having itslowerend communicated through the bottom of the chamber to the open air, and having its upper end closed and positioned within the discharge, the sides of the upper end of the tube being provided with a series of circumferentially spaced holes, and an intermediate curved portion of the tube being provided with an aperture through which the said main fuel jet is projected into the tube, and means carried by'the upper end of the tube capable of being adjusted to control the passage of fuel from, said jet and through said holes.
2. A fuel economiz er of the type described comprising a conventional carbureter having affuel mixing chamber and a main fuel jet within the chamber, -a double bend tube havingan aperture at the bottom of one bend to permitzthe tube to beslipped upon said main fuel jet and to receive the upper portion of said main fuel jet interiorly and to a height near the upper end of the tube, the lower end of the tube being projected through the lower wall of the mixing chamber and communicating with the exterior air and the upper end of said tube being provided with holes and an annular restricted portion and means co-operating with the main fuel jet to control the flow of fuel therethrough for mixing with air in said tube and diffusion thrgugh said holes upwardly into the manifol In testimony whereof I afiix my signature.
