e the following is a full, clear, and exact deters.

scription thereof, reference being had to the accompanying drawings.

The object of this invention is to improve the construction and operation of carbure- One feature of the invention consists in mounting the air inlet valve and the throttle valve on the same shaft or otherwise so as 4 to be operated by the throttle lever simultaneously and to the same extent. To this end said valves are mounted in the same plane for controlling the inlet and outlet passages which are parallel. Along with the foregoing is an arrangement operated alsoby thethrottle lever to operate the fuel inlet so that said throttle lever simultaneously actuates the air inlet valve, the fuel inlet valve and the throttle valve, and to the same extent. I

. These and the other features of the invention will be understood from the accompanyi-ng drawings and the following description and claims.

In the drawings F igure 1 is a central ver.-' tical section through the carbureter with the parts in idle position. Fig. 2 is a horizohtalsection on the line 2-2 of Fig. 1. F ig.-;3 is averticalsection on the line 33' of Fig. 2. Fig. l is a horizontal section on the line L4 of-Fig. 1. Fig. 5 is a vertical section on the line 55 of Fig. 1. Fig. 6 is a vertical section on the line 6-6 of Fig. 1. Fig. 7 is a horizontal section on the line 7-7 of Fig. l.

In detail, 10 represents a float-chamber being substantially semi-spherical in vertical section, as shown in Fig. 1.

11v is a float which is U-shaped, as indicated by dotted lines in Fig.2. It is mounted on the lever '12 fulcrumed on the pin 13' in the extension 14: from the float chamber and actuates the valve 1'5,'which regulates the supply of fuel through the inlet 16.

- The top 20, which closesthe float chamher, is held down in place by an annular threaded ring 21, and itcarries the carbureting chamber 22, which extends down into the float-chamber. The air inlet 23 extends :albove the top 20, and the gas outlet24 likewise extends above the top 20 and is par- Specification of Letters Patent.

being separated by a partition 25.

The shaft 26 extends transi'ersely through the air. inlet 23, partition 25 and gas outlet 24, andcarries two disk-valves 27 and 28, the former being located in the air passage, and the latter in the gas outlet passage and constitutes the throttle valve. These two valves are secured to the shaft 26 so as to be in the same plane and normally close the two passageways. Said shaft is actuated byathe throttle lever 30' secured'on its outer en r A fuel nozzle 31' projects upwardlyin'to the carbureting chamber 22 and preferably under and in vertical alinement with the gas outlet 2-1. It is closed by a needle valve 33, which has guide pins 3l therein, as shown in Fig. 4. The nozzle 31 screws into .place' and valve 33 is loosely pivoted to a allel with the inlet 23, the two'pas s'ageways Patented-July 30.19125 Application filed December 1, 1910. Serial No. 595,137. 1.

through which a pin 37 from the valve projects, as shown'in Fig. 1. The lever 35 lies in the float-chamber belowthe carbureting chamber and is fulcrumed on a pin=38 at one endand at the other end is loosely connected with an internally threaded rod 39. Said rod has a pin 40 in it which-projects loosely into .a slot 41 in the lever 35. The rod 39 screws on another rod l2 which projects upwardly through the top and has a head 43 which is engaged by thehead of the throttle lever. This head is semi-spherical, as shown in Fig. 5, so that-when the throttle lever is moved from the' full-line position in that figure to the dotted-line position, the rod 12 will be dropped, and consequently the lever 35-and the fuel valve- 33. The rod 42 and associated parts are held in, their upper position by the flat-n passing out through the passageway 24 is given. The movement of the lever 35 is stopped by the adjustable screw 45 wh ch extends through it and engages the bottom' of thecaJrburet-ing chamber, as shown'in Fig. 1. 7

At one side of the device a fuel flushing means is shown,,-as appears in Figs.; 2 and. 3. A rod50 is vertically reciprocahle through on the plug 51.

a plug 51 which screws into the top 20 of the float chamber 10, said rod 50 extending down to the float. On an arm 54 from the plug 51 a lever is fulcrumed between its 5 :endsso as to engage'the upper end of the the valve mechanisms and adjustments therefor and the union 21 for securing said top to the float chamber, enables the top,

which carries all of the valve mechanisms, to be adjusted .or turned to any desired position according. to the requirements of the machine in any particular case and it can be secured at any adjustment'by the union 21. Although the fuel 'su ply pi e 16 may have to be in a certain xed re ation, the valve mechanisms and throttle can be turned 'to any position. This is a very great advantage in equipping automobiles and other devices with carbureters.
