FEED-NOZZLE FOR CARBURETERS.
Specification of Letters Patent.
Patented Jan. 9,1912.
Application filed December 5, 1910. Serial No. 595,778.
To all whom it may concern:
Be it known that I, DAVIS BARNARD, a citizen of the United States, residing at Los Angeles, California, have invented a new and useful Feed-Nozzle for Carburetors, of which the following is a specification.
Among the objects of this invention are to provide a feed nozzle for carburetors that can be more easily and accurately regulated to deliver the exact amount of liquid fuel required by the carbureter, and also a nozzle that will at all times deliver a thin sheet of liquid fuel that can readily be taken up by the air in the carbureter.
Further objects are increased lightness and compactness of construction and lessened cost of manufacture.
A feed nozzle constructed according to the principles of this invention is provided with a longitudinally movable plunger to regulate the size of the feed opening, the size of said opening being varied at a uniform rate per unit of movement of said plunger.
The invention is well adapted to use on vehicles driven by internal combustion en- This nozzle may be assembled in combination with carbureters differing considerably in construction, but it is designed more particularly for use in combination with the carbureter described in my copending application Serial No. 581,212 filed September 9, 1910. The general construction of the car bureter herein shown is not claimed in the present application.
Referring to the accompanying drawings, which illustrate the invention: Figure 1 is a longitudinal section of a portion of a carbureter showing the casing of the nozzle in section within the chamber of said carbureter; Fig. 2 is a broken enlarged vertical section of the nozzle proper; Fig. 3 is a plan view of the nozzle on the scale of Fig. 1, showing the means for adjusting and operating the same. The bifurcated operating lever is shown in section; Fig. 4 is a cross section on line :2 of Fig. 2, but on a still larger scale.
Referring in detail to the drawings, in Fig. 1 is shown a portion of a carbureter within which is mounted my improved feed nozzle. Said nozzle comprises a tubular casing 2 having a longitudinal feeding slot 3 the opening of which is regulated by a movan annular chamber 6 around that portion of q the plunger. Into said annular chamber the fuel is fed by any suitable means as by the conduit 7, and from said annular chamber the fuel passes into the plunger through perforations 8 with which said reduced portion is provided. A
As shown in Fig. 2, plunger 4 is closed at the left end by a milled head 9 to maintain that end of the plunger and .casing closed at all times. Said plunger is provided with screw-threads 10 which engage with the threaded bore of a block 11 (see Fig. 3). Said plunger may therefore be rotated and thereby be moved longitudinally, to partially or wholly open or close feed slot 3.
11 is a lock nut to secure the plunger in adjusted position.
The right hand or delivery end of the tubular nozzle casing 2 is provided with a closure plug 17. In addition to forming a closure, said plug forms a support for a spring wire 18 which atall times extends into the open end of plunger 4. Said spring is provided with an upwardly bowed end portion 19 which presses against the upper side of the inner wall of the plunger to cause said plunger at all times to fit snugly against the slotted portion of the cas- .ing 2 thus preventing any escape of liquid from the portion of the slot along side the plunger.
The general construction of the carbureter shown in Fig. 1 forms no part of the present invention and will only be referred to briefly. The air enters through the inlet 21, ascends on each side of the nozzle and passes out opening 22 on its way to the engine. Said openings 21 and 22 consist of slots of uniform width, their length being simultaneously regulated by a sleeve 23 operated by a rod 24 which is moved by an arm 25, to which is connected the operating rod 26. Said arm is adjustably connected with operating lever 16 of plunger 4 of the nozzle by means of a link or yoke 27 to one end of which is pivoted a block 28 that slides in a slot 29 in arm 25, said yoke having a screw threaded engagement with a rotary sleeve 30 mounted on lever 16. A stop arm 81 limits the movement of arm 25 and lever 30 toward the carbureter. The construction just described affords means for regulating the minimum a-ir feed and fuel feed and also for proportioning the opening and also the closing movements of the air-controlling sleeve 23 and the fuel-controlling plunger 4. The uniform width of the fuel feeding slot 3 causes the same to vary in size in equal amounts per unit of movement of the plunger 4 and insures perfect regulation.
In operation, the plunger of the nozzle is I rotated by its milled head 9 to regulate the minimum spraying opening of slot 3, when arm 25 is in contact with stop arm 31, to determine the feed when the engine is running without load. This adjustment is in- I dependent of the regulationeffected by the main operating rod 26 during the operation of the engine under load.
Although the invention has been described in connectionwith and as especially designed for a carbureter, it is not limited to such use, but maybe used in other relations if desired.
Although the spraying slot of the nozzle is illustrated as being through the outer tube of the two telescopic members of which the nozzle is constructed, yet it will be understood that a nozzle constructed with the inner tube stationary and the spraying slot therethrough, would involve a mere reversal of parts and would lie within the scope of this invention. Various other changes of j fuel to the interior of said plunger, and a construction within the scope of the appended claims may be made by those skilled in the art without departing from the spirit of the invention; a
I claim:
