To all whom it may concern:

Be it known that 1, WILLIAM H. OGDEN, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a certain new and useful Improvement in Carbureters, of which the following is a full, clear, and exact descri tion.

In the use 0 carburetors with internal combustion engines, especially engines of the high-speed, multi-cylinder type there is always more or less condensation of gasolene in the combustion chambers of the cylinders and in the intake manifold due to imperfect mixture of the gasolene with air; loss of power at high speeds and at low speeds under heavy load due to improper mixture and a consumption of gasolene all out of proportion to the power developed, and in the case of engines used in automobiles and other vehicles to the distance traveled. l have found\that by constructing a'carbureter in accordance with my invention here-'- inafter explained, the faults above men tioned are practically eliminated.

The object of this invention is to provide a carburetor which will insure the complete vaporization of the gasolene and afl'ord a perfect mixture at all engine speeds and. under varying loads, thus eliminating waste 7 of fuel and insuring at all times maximum efliciency of the engine with which it .is

used, with a minimum consumption of gasolene. Although the carburetor of this invention is designed primarily for use with gasolene, it has been found to give very satisfactory results with the heavier hydrocarbons, suc as kerosene.

My invention contemplates the arrest in the carburetor itself of the fuel which has not entered into a homogeneous mixture with air by virtue of the physical phenomena of capillary attraction, viscosity, coho sion and adhesion, in such way'that the thusdetained liquid may be subsequently J subjected to mixture with air and be.uti] ized for supply to the engine in efficient form,

without liability of its entering the intake or the engine cylinders in liquid form, as I will proceed now to explain and finally claim.

In the accompanying drawings illustratmg the invention,

Fig. 3 is a partial elevation looking toward the right of Fig. 1-, showing the automatic adjusting device. Fig. 4 is a view of the lower portion of the carburetor taken on line IV.-IV of Fig. 1.

Referring-to Figs. 1 to 8, inclusive, the carbureter has a body, portion. formed preferably of two parts 1 and 2, suitably secured together by screws 3 or bolts and nuts. The

) for the main and auxiliary air inlets 5 and 6, respectively, and have circumferentially arranged channels which in conjunction with similar complementary channels in the communicatin with the sunken portion 15 in the several figures of 'WlllCh. like parts are similarly designated,

part 1 form passages 13 and 14 respectively constant level by means of a float 25 supported by an arm 26 which is dpivotally connected to an ear 27 on the un bed 10, and this float is connected by a suit able link 28 and lever 29 to a valve 30 sup ported by the lever 29 which is pivoted on an extension or arm 31 formed, on the shoulder 17 and this valve 30 is operated by the float to open and close the gasolene port 32. In place of the valve and float arrangement here shown, any other approved form may be used which will perform the proper functions.

11 air passage 33 extends from the main air inlet to the gasolene chamber 23 and opens into said chamber at a point below the level of the gasolene therein.

The bed 10 is formed on its upper face with a recess 34 concentric with the gasolene chamber 23 and adapted to receive a bearing spider 35 andhold it in axial alinement with the gasolene inlet 24. This 7 spider has a downwardly projecting exten- 'sion 36 which conforms to the shape of the gasolene chamber '23 and extends into it thereby forming an annular passage 37 through which the gasolene must pass in reaching the mixing chamber 38 of the car bureter. The upper face of the spider 35 is formed with an inverted conical ste 39 to receive the lower similarly shaped earing end 40 of a spindle 41 upon which is mounted a rotor formed of a series or nest or any suitable number, preferably a plurality of disks 42 spaced apart by any as washers 43 and supported by and rning with the spindle.- The upper end of the spindle 41 is screw threaded to receive a clamping nut 44 which holds the disks in pro er relation to each other and to the spin le, and the upper face of this nut is provided with a conical bearing face 45 which fits a similarl and true revolution of the formed bearing 46 in the end of a sleeve 4 having its upper end threaded into a neck 48 formed on or applied to the pa'rt 1 of the body portion of the carbureter. By adjustment of this sleeve 47 toward or away from the nut 44.the spindle and its assembled disks may be made to .run in a tight or loose hearing, as desired. 'A bushing and bearing ring 49' is seated in the up per part 1 and is so arrang float in its seat so as to insure the proper disks and to cause er side of the ed as to partially needle valve seats in the gasolene inlet 24 and may be adjusted to increase or diminish the supply by means of a hand wheel 54 at the upper end of the valve. The adjusting screw portion 55 of the needle valve is threaded into a sleeve 56 internally screwthreaded to receive it and screwthreaded externally to coact witha complemental thread in the neck 48.. This sleeve has a laterally extending operatin arm 57 provided with a finger 58 whic engages the notches on a wheel 59 fixed on the upper end of the stem of the needle valve, and this arm is connected by a bell-crank lever 6.0 with an arm 61 adjustably mounted on an extension 62 of a. puppet valve 63 arranged in the auxiliary air intake 6, so that in case of high speed or heavy load of the engine and consequent increased} suction, the auxiliary air inlet valve 63 will, through the arm 61, lever 60, arm 57, finger 58 and wheel 59, turn the needle valve to increase the gasolene supply. The valve 63 may be of ordinary construction, and is here so.

shown, having. a stem 64 slidabl mounted in a bearing 65 and backed up and held normally closed by a spring 66. Referring particularlv'to Figs. 5 and 6, the disks 42 are preferably circular and formed by stamping or otherwise, with centrally arranged vanes 67 bent. up at an angle from the plane of the disk and with stops 68 bent down wardly, for the purpose when the disks are nested with the spacers 43 between them, of preventing the vanes from contacting with each other. Thus it will be seen that when the disks are nested or arranged in a series, one above another, there will be a space between each disk and that one next 3013081117 to it, caused by the spacers 43, and there will also be a corresponding space between theupper and lower faces of the vanes of superposed disks caused by the stops 68. Each disk has acenter opening 69 for the purpose of mounting it upon the spindle 41. The formation of the vanes 67 from the metal of the disk leaves a series of openings 70 through which the vanes of disks below it may project; As -many of these disks may be used as the requirements of the size of engine and corresponding size of carbureter demand. I

The lowermost disk 71 of the rotor or nest of disks, as shown in Fig. 7, differs from the others in'that it is imperforate and has no vanes and forms a seal over the bottom of the rotor, thereby causing all mixture and gasolene to pass under the rotor to the chamber 38 and thence enter the rotor between the disks at their peripheries.

Referring to Figs. 10 and 11, wherein a modification of the invention is shown by which it is adapted for use with known carbureters, only such parts of the device of-the invention are used as are necessary to incorporate its principle. attachment is so made as to permit of the installation in known carbureters of the principle of the rotor formed of disks. To this end, there is a two-part .body portion having an upper part 72 provided with an outlet 73 having the usual butterfly or other throttle valve and coupling flange (not shown), and a lower part 74: provided with an inlet 75 and coupling flange 76 for attachment to the flange of a carbureter, so as to conduct hydrocarbon mixture from the carbureter to the device of the invention. The part 74 has a bed portion 77 provided with a centrally arranged step 7 8 to receive a spindle 79 upon which the disks 42 are mounted and held in position thereon by a nut 80, these three last mentioned parts be ing similar to those already described. The bearing face 81 of the nut 80 seats in an adjustable bearing post 82 threaded into a neck 83, its adjusted position being maintained by means of a lock nut 84. The bed portion 77. is provided with a series of circumferentially arranged openings 85 so formed as to admit mixture from the at tached carburetor with a whirling motion and tangentially to the disks, and the spacers 86 may be beveled,if desired, to offer as little resistance as possible to the upwardly fiowin mixture. A packing and bearing ring 8 is provided, as in the case of the carbureter before described, to assure the easy and true revolution of the rotor and to prevent escape of mixture into the outlet by its passing around and over the rotor, thereby insurin the escape of all mixture through the. aces between the vanes of the disks.

The main principle of the invention being embodied in both forms of the device shown and described, a' description of the operati'on of one form will suflice for both.'

Referring to Figs. 1 to 9, inclusive, gasolene or other liquid fuel is supplied at 20 and through duct 19 and port 32 enters the float chamber 22 and rises to a predetermined height therein and in the chamber 23 which it enters through inlet 24. This height of the gasolene, or gasolene level as it is called, is kept constant by means of the float 25, in the usual manner, and as described.

The suction in the carbureter caused by the engine to which it is attached, draws air- That is, the

in through air inlet 5 and passage 13 and this air enters the chamber 38 tangentially owing to the circumferential arrangement of the passage 13, and moreover, it enters in a small current and with considerable force due to the constricted area of the opening 88 of passage 13 and forms a whirling current within the chamber 38. This current of air, in order to reach the outlet 7, must pass between the disks 42 and their vanes 67, and in so passing it imparts a rapid rotary motion to the rotor or nest of disks.

In addition to the current of air just described, an additional small jet of air is sucked in through the inlet 33 and is introduced below the level of the gasolene in chamber 23, thereby forcing the gasolene out of chamber 23 through annular passage 37 into chamber 38, where it is sucked into the nest of disks. When the gasolene in this partially'atomized form is brought in contact with the surfaces of the disks, any portion of the liquid not homogeneously mixed with air but merely held in suspension is deposited on the disks, and the capillary attraction caused by adherence to the superposed adjacent faces of the disks and the cohesion present in the particles of the gasolene causes them to be arrested between the disks and form a thin film therebetween. The rapidly revolving disks will, by their centrifugal action, discharge a certain quantity of the accumulation of liquid gasolene from between them and into chamber 38, where it will be again picked up by the whirling current of air and re-introduced between the disks. These tion, capillary attraction and centrifugal force, together with a certain amount of viscosity present in the gasolene itself, make it impossible for much, if any, gasolene in liquid form to pass between the disks and their varies with the outrushing current of air. It will, therefore, be .evident that what gasolene passes between the disks and between their vanes '67 to the outlet 7 must be very finely atomized and so mixed with air as to form a completely combustible mixture. The exhaust from an engine with which this carbureter was used was color-- which fact would tend to less and odorless, the belief that the vapor furnished by the carbureter to the engine contained no free gasolene and was completely combustible. This is also evidenced by lessened gasolene consumption.

, Under conditions of high engine speed or heavy load the auxiliary air valves 63 will come into operation, thus admitting additional air through passage 14 in a whirling current as in the case of that admitted through the main air inlet 5.

The rapidity with which the gasolene may enter the chamber 23 is regulated by means of the needle valve 51. a

three forces, suc- The supporting arms 89 of the bearingspider 35 may be beveled, as shown most clearly in Figs. 8 and 9, to offer the least possible resistance to the upwardly flowing whirling gasolene.
