Application filed. January 15, 1907. Serial No. 352,358.
lowing is a specification.
This invention relates to spray carbureters for internal combustion engines, and has for its object to provide simple means for controlling the same, and for obtaining correct proportions of fuel to air under al conditions.
A further object is tol provide ineansforl adjustment whereby such proportions can be varied.
According to this invention, around the jetnozzleV is arranged `a hollow cylindrical plug cock adapted to control the air admitted to the mixing or jet chamber on the one side, and the carbureted air outlet onthe other side, and attached 'to this rotatable plug cock is a device whereby the outlet from the j et-nozzle is simultaneously controlled.
In one construction, the jet nozzle may have its outlet eccentric, and over the nozzle may be arranged a ca having asimilar eccentric orifice, the cap eing connected to the rotatable plug cock so that the holes in the cap and jet nozzle may be caused to coincide wholly or partially according to requirel ments. I
In another construction, the rotatable cock may carry a needle valve which is adapted toA f' screw into or out of the jet nozzlev and so cut down or enlarge the outlet, In this case the screw thread which raises or 'lowers the needle valve7 or its seating, may be varied in shape to obtain lthe required result'.
In the accompanying drawings, Figure. 1 is a central vertical section of one form Aof carbureter constructed according to this invention. -Fig. 2 is a part horizontal section on the line 2-2 of art of saine. Fig. 3 is an enlarged sectiona view showing the j et-nozzle'controlling-device, the parts being separated slightly for the sakeo'r' clear-ness. Fig.
V 4 is a side'elevation of one of the adjustab lstops employed, and Fi 5is a section showing art of almodiied orm of Carbureter.
Like letters indicate like partsthroughout the drawings. V
In the con truction illustrated in Figs.
1 to 4, the fue is maintained at a constant.
height in the jet nodzle A by vmeans of a float B acting on the needle valve C through the medium of levers D in the .usual manner.
The jet chamber E is formed so as to receive a, cylindrical piling cockF, cut away at F1 F2 as shown. -T 's cylindrical cock is arranged concentrically with the 'et nozzle A and is adapted to control the air-inlet\G to the jet chamber, and thev carbureted air outlet H from the jet chamber. by rotatin the plug cock as'will be easil understoo For this purpose the plug coc r is provided with a spindle F? suitably supported, and having attached to it a lever J whereby it is rotated.
The jet nozzle A, as will be seen, especially in Fig. 3, is of somewhat larger dimensions than usual, and is conveniently conical at its upper end A1. On thisV up er end b ars a cap K formed at its base wit a disk K1 hav-v ing in it a hole K2. Into this hole K2 projects a pin L,'carried bytherotatable plug ycock F. This plug cock bears upon the disk K1, the pin L engaging the hole .K2 so that rotation of the plug cock rotates the disk K1 and the cap K. To insure the cap K fitting closely upon the to spring M is interpose( between the top of the ug'cock and an suitable abutment, tending to force the p ug cock, and consequently the disk K1 and cap K downwardly.
In the upper end Al of the jet nozzle is made. the usual small outlet for the fuel. This is arranged eccentrically, as shown at A2, and in the cap K is a similarly eccentric hole K3, which is adaptedv to coincide with the hole AZ in the jet nozzle, when in one osition of the cap and plug cock, and to gra lually move out of line with the hole A2 as the pli'igcock is rotated. Thus the outlet from the jet nozzle is minutely controlled by the rotationof the plug cock.
In o i eration it will be understood that the air to e carbureted'enters at G, and passing at a high velocity around the jet nozzle A, takes up some fuel and is carbureted. This carbureted 'air passes out by way of the outlet H, to be used "as required. To throttle down the supply of'carbureted air-the plug cock F is rotated by means of' the lever J to the required position, thiseiiecting the de sired purpose by bringin less of the cut.-
away portion F1 opposite t e outlet H. Fur-A ther, it will be seen that the air inlet G is similarly and simultaneously cut down byv the plug cock. At the saine time also the 4 80 of the jet nozzle, a
, 65 bureted air outlet.'
rotation of the plug cock rotates the disk K1 and ca K, which, as mentioned above, reduces t 1e outlet for the fuel from the j et nozzle A. Thus, it will be seen that the air inlet,
5 fuel outlet and carbureted air outlet are alll controlled simultaneously.
For purpose of primary adjustment in fitting the carbureter, the holes A2 K3 can be arranged at any suitable distance from the center by varying which different eflects are obtained. Again, further adjustment can be obtained by varying the position of cut-off yof the plug cock in regard'to the inlet G and outlet H. For this urpose between the 'plug cock and the wallpof the jet chamber is arranged a cut-off cylinderl N. This has cut-away portions N1 corresponding to the cut-away portions F1 F2 of the plug cock, and
is provided with a suitably su ported stem O to Which is attached' a lever enabling lit to be rotated as desired.
Suitable stops are made to limit the rotation of thelever J, and. similarly locking devices may be made for the lever P, so as to lock the latter in the correct position after the primary adjustments have been made. For this purpose the cover R of'the spra ing chamber is formed with a circulartrac or recess S, in whichlie stops. These consist of 13,0 nuts T carried by screws T1, the heads of which lie in the recess S. These stops, as Will be seen, stand up above the cover R into the-path of the levers P and J. As they are adjustable in the recess S, they may be set apart to provide stops limiting the motion in feither direction as is the case of the lever J, or a pair of them may be adjusted to bear against the lever P, one on each side to prevent that lever being moved accidentally 40 after the made.
In the mddification illustrated inv Fig. 5,
the jet nozzle A2 is open concentrically at the top, the orifice being slightly conical as will be seen at A3. Standing up in the jet chamber are a number of supports or columns U which sup ort a bearing plate V.v Throu h a hole in t is bearing plate V passes a nee le valve W, the lower end of which is adapted to drop into the conical orifice A3, while the upper end V1 is screw-threaded and engagesl a screw-threaded hole F4 in the lug cock spindle F3. The needle valve is made non-circular in cross section at the part W1 where it passes through the bearing plate V. The hole in the bearing late is similarly 'shaped,. so that the nee le valve is held against rotation butfcan rise and fall. Rotation of the plug cock F by means of .the
lever J, causes the needle valve W to rise and fall owing to the engagement of its screwthreaded portion therewith. In this 'manner the jet nozzle orifice is enlarged or decreased I simultaneously with thc air inlet and the carchamber, substantially as set forth.
primary adjustments have beenv What I claim and desire to secure by Letters Patent of the United States is 4 1. In combination, a jet nozzle, means for maintaining the fuel at a suitable height therein, a mixing chamber having an inlet 70 thereto and an outlet therefrom, a rotatable plug cock arranged in said chamber and adapted to control said'inlet and said outlet,
a jet-nozzle controllincr device connected said plug coc with .a hole in said capfcor-4 responding to said orifice. in the jet nozzle, an adjustable cylinder ,arranged around said' plug cock with holes corres onding with said inlet to and said outlet from theanixing 3. In combination, a jet nozzle having an eccentric orifice, means for maintaining the fuel at a suitable height therein a mixing chamber having an inlet thereto and an outlet therefrom, a plug cock rotatable in said chamber, a pin on said )lug cock, ay cap for the jet nozzle rotatableby said plug cock, with a hole in said cap corresponding with said orifice in `the jet nozzle, a disk on said`cap with a hole engaged by said pin on 'the plug cock, an adjustable cylinder arranged around said plug cock with holes in said cylinder corresponding with said inlet to and said outlet from. the mixing chamber, Substantially asset forth. j Y
4. In combination, a jet nozzle having an eccentric orifice, means for maintaining the fuel at a suitable height therein, a jet chamber having an inlet thereto and an outlet therefrom, a plug cock rotatable in said chamber, a in on said plug cock, a cap for the jet nozze rotatable by said plugcock with a hole in said cap corresponding to said orifice in the jet nozzle, a disk on said carp with a hole in said disk engaged by said pln" on the'plug cock, an adjustable cylinder a1".- ranged around said plug cocl-- 'ith holes in said cylinder corresponding .h said inlet'r to and said outlet from` the jet chamber and a spring bearing on said plug cock, substantially as set forth. i l
In testimony whereof I have signed my name to this specification .in thepresence rof two subscribing witnesses'.
