EMERY H. FAI-IRNEY, F OAK PARK, ILLINOIS.
CARBURETER.
Specication of Letters Patent.
Patented Apr. 4, `1916.
Application filed November 26, 1915. Serial No. 63,571.
To all whom t may concern.'
Be it known that I, EMERY H. FAHRNEY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Carbureters, of which the following is a speciiication.
This invention relates Particularly to f carbureters for internal combustion engines utilizing a liquid fuel, such as gasolene.
The primary object of the invention is to provide simple and eflicient means for automatically regulating the position of the valve which controls the admission of hydrocarbon fuel to the mixing chamber.
The invention is illustrated, in'vits preferred embodiment, in the accompanying drawing, in which n FigureA 1 represents a vertical sectional view of a carbureter constructed in accordance with the invention; Fig. 2, a horizontal sectional view taken as indicated at line 2 of Fig. 1; Fig. 3, a vertical sectional view of a cam which serves to automaticallyvary Vthe position of the needle valve controlling the passage or nozzle leading from the fuel chamber; Vand Fig. 4, a similar view, showing a slight modiication of the cam.
In the embodiment illustrated, A represents the float-chamber of a carbureter, which may conveniently be of circular form in horizontal cross-section; B, a top for the chamber A, which is formed with a shallow chamber B1; C, a tubular member which.
extends through the chamber A and affords a vertical main air-intake passage C1, the
member C beingprovided interiorly with a,
cross-piece cr bridge Cwhich carries the nozzle C3; D, an auxiliary air valve controlling the admission of additional air to the chamber B1; E, a conduit connectedwith the member B and communicating with the chamber B1, the member E being carried by a conduit-section E1, which connects with the manifold of the engine and which is equipped with a throttle-valve E2; VF, a
needle-valve controlling` the passage of liquid fuel from the nozzle C3, the needlekvalve having a threaded shank portion 1 engaging the threaded bore of a fixed sleeve 2, which 'forms a part of a bridge-piece disposed in the upper portion of the passage C1 and which is formed integral with the upper portion of the sleeve C; G, a cam sleeve provided interiorly with a spiral rib or spline 3, which engages a vertical groove in the peripheral portion of an automatically actuated disk or follower L1, which is slidable vertically on the squared shank portion 5 of the needle-valve F and yieldingly held in a depressed position by a coil-springY 6, the tension of which is Vadjustable by means of a nut 7 having screw connection with the reduced upper porticn of the shank of the needle-valve, the shank of the needlevalve Yalso having a further reduced extension 8, which moves-ina vertical guide 9 formed in a spider 10 with which the upper portion of the member E is' provided; and
H, a valve controlling the admission of fuel to the chamber A, the valve I-I being actuated by a lever H1, controlled by a float Htlocated in the chamber A.
vThe form of the parts of the carbureter and the construction may be varied greatly. In the form of embodiment selected for illustration of the invention, the chamber A has al cylindrical vertical wall surmounted by the top B, and has a curved bottom wall 11 provided with a central vertical opening;
The member C has a iang'c 12 near its l upper end and a threaded reduced extensionV above said ange, which is screwed into an intericrly threaded opening tapping the bottom of the chamber B1; and the member 'Y C is provided near its lower end with a flange 13, beneath which is a reduced extension' 14e, which extends through the opening in the bottonrll, the extremity of the portion 14 being` threaded land fitted with a nut 15. A gasket 16 is interposed between the flange 13 and the'bottom wall 11 of theV chamber A. .The cross-member C2 isy provided with an oil passage 17, which Ycommunicates at its ends withthe interior of the chamber A, and which is intercepted centrally by the vertical passage 18 of the nozzle C3. At the upper end of the nozzle C3 is a conical seat for the valve F.
VThe top member B is of suitable form to close the upperend of the float chamber, and Y is provided with the embossment 19 in which the chamber or passage B1 isformed.V
The auxiliary valve D may be of any suitable form. As shown, it comprises a disk 20 which is provided with a stem 21, working through the spider 22 of an annular nut 25, which has screw connection with the embossment 19 of the top member B. The stem is encircled by a coil-spring 2l adjustable by means of a nul zo, connected with the upper end of the stem 2l.
"lhe member ill is provided near its lower end with a flange 2o, which bears upon the upper surface of the embossment lt); and the member has an extension :27 which lits snugly in a bore provided in the upper Wall of the chamber' B1.
The valve l?, controlling the discharge of the nozzle or jet C3, may be of any approved form. 'lhe threaded portion l of the valve stem should turn freely' in the threaded bearing 2, which constitutes the hub portion of a spider 2a formed in the upper portion of the conduit C.
The sleeve G- is ixedly secured in the lower portion of the conduit E and is capable of angular adjustment. lt is confined in the enlarged lower portion of the conduit E by a threaded ring or nut 28; and, as shovvn in Fig. 2, it is provided peripherally with a series of recesses or sockets 29 adapted to receive an implement, by means of which the sleeve may be adjusted or turned Within the conduit. To aiioid access, the conduit E is provided with a segmental slot 30, guarded by a closure 3l, which may be moved out ofthe Way to give access to the slot. rlfhe sleeve G is secured in adjustable position by means of a set-screw 32.
The cam-rib 3 may be formed integrally with the inner surface of the sleeve G. It may be in the form of a spiral of very high pitch, as indicated. lt engages a peripheral notch 3a with which the disk el is provided; and the cam-rib 3 and notch or groove 3 may be regarded as cam vconnections between the disk el and the sleeve G, which, in turn, is xed to the Wall of the conduit E.
The passage through the members C and E and the intervening portion of the chamber B1 may be regarded as the air conduit or mixing chamber of the carbureter, communicating through the member la with the enrrine7 or With the'manifold of the engine; and, as indicated above, the chamber B1 also affords a lateral air intake, the admission to which is controlled bythe auxiliary valve D. The bridge piece Cl of the member C has depending therefrom a threaded stem 33, upon vvhich is adjustably mounted an air regulating deviceV 3l, bv means of which the main admission port 35 of the carburetor is regulated.
v The valve H controls an oil admission passage 36, with which communicates a pipe 37 leading from the oil reservoir. The construction of the valve H, the lever lull and float H2. may be of any approred design. In the illustration given` the lever H1 is connected 'with a pivot 38 carried by lugs 39 depending from the top member B of the fuel chamber A. As is Well understood, the ralve il operates to maintain a constant head of oil in the chamber A.
ln the carbureter illustrated, the chamber containing the'gasolene is of annular form, the detachable tubular member C forming the inner Wall of the annulus. In this de` sign, a vertical air passage Wholly through the carbureter is afforded.
nalfig. Ll, G1 represents a sleeve equipped interiorly with a cam-rib 3b. The construction is similar to the construction shown in Fig. 3, except that the pitch of the cam-rib is varied, becoming greater or steeper at the' upper portion, so that the needle-valve F, when this form of cam-rib is employechwill be rotated less as the follower slapproaches the upper end of the Vcam-rib. In practice, the cam-rib will be given such inclination or pitch, in its various portions, as will give the best results for the particular engine toY vrhich the carbureter may be applied.
The operation of the carbureter is asefoly lows: The desired tension upon the spring 6 is secured by adjustment of the nut V7. T he sleeve G is angularly adjusted 'andi initially set in such position as tov hold the Y valve F open the properdistance to supply the oil needed for low speed of theengine. As the tlirottlevalve E2 isopened the speedA of the engine increases, thereby increasing the suction in the conduit E. The increased velocity of the mixture passing through the conduit causes the follower Il torise against the pressureof the spring 6, the fole lower sliding on the squared or splined porf tion 5 of the stem of thevalve F. As the follower e rises, it is caused to rotate through the medium of the cam-rib 3, thereby turning the needle-valve in its threaded bearing L, causing the valve to open to ad mit an increasedamount of gasolene to the mixing chamber. `When the engine. slows down, the spring then depresses the follower 4;, thus turning the valve in the opposite direction and causing it to return to the slovvspeed position. As has been indicated, the various portions of the cam-rib may be given such inclination as will secure the proper mixture at various speeds of the engine. l l
The construction' described is simple, and
enables certainty of results tobe obtained. it
being' understood that the cam `rib 3 is rigid and so designed as to turn the needle-valve with precision. Y
The foregoing detailed descriptionV has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, but the appended claims should be construed as broadly as is permissible in view of the prior art.
