Speoiiication of etters etent. Patented Den, 3i, 2193126 sppucauon mearrebruary e, wie. empi :wegennet new and usel improvements'in Carburetere, et which the following is a specification. My invention relates to improvements in eerbui'eters for gee engines, etc., end ymy 0bects are first, to provide e carburetor o eimple end durable design, and in which the customary dusting chamber is dispensed with; second, one 1n which the vulves coutroiiing the ges mixture to the engine muy he actuated manuell to initially start the engine, endeutonintieally after the engine hes started; third, to provide novel ineens for admitting sir to the mining chamber of the eerbureter, and fourth, to provide novel means for simultaneously actuating the air inlet valve and the throttleV valve of the carburetor.

@ther tentures of the invention will hereineter eppeer, and inA order thatsaid invention may be fully understood, referenceA will now be mede to the accompanying drawings, in which:

Figure 1 is e side elevetionof my improved cerhureter. Fig. 2 is e central vertical section of the cerbureterm Fig. 3 is a horizontel section on iine lli-iii (rf-Fig. 1. Fig. el is a horizontal section ori-line V-IV o I of shell 1, as shown in Fig. 2. Head 3 has e plurality of inlet ports 5, for the admission or" air, and e centrally-disposed vertically-extending tubular member 6, which extends upward into shell 1, und terminates in e conical valve seat 7, the lower portion of said tubular member communicating with e supply-pipe 8, through which gusolene is supplied to the Carlini-eter from a tank, or,y

other suitable source7 not shown.`

9 designates a conical screen secured et its lower end to the interior of head 3 and :it

its upper end to the upper portion of the tubular member 6. i

10 designates e needle vulve normally I pressed, to its sent-7 lby e. coil spring 11,. in terposed Abetween a transverse guide'l)J and the boss 13 of a disk-valve 111, threaded upon 'the needle vulve 10 'and normeily seated upon en annular 'l'iliiige 15, es shown in Fig. 2; Valves 10 and 14 'open end close simultaneously, and in order that weer oit the valves, or their respective seats, they he taken up, valve 14 is edjustubly-mountezl si upon valve 10 and reliably-secured et @my point of its adjustment by e lock-nut it, engaging lthe threaded portion 17 of valve 10. The up er portion of the needie-ynlve 10 extends t rough guide 12 and is thereby fl heid in axial alinement, when open,witii its seat 7.

18 designates s throttlevalve mounted upon a rock-shaft 19, journaled in opposite sides of the reduced tubular cap 2./ Throttle 18 is oontrolle by e iitedlymounted crank 21 pivotall -eonnected et its e free end 'to e connecting- M22, herring; e pinelnd-slot connection 23 et its lower termiuel with an air-valve 2e, having e circulerrow of ports 25 adapted to register with a like row of inlet ports26 in one sigle ofi the shell to which letter valve 24 is pivoteiiysecured by e screw 27.v

28 designates n push-rod forming peint 'menuallycontrolled means to open the valves 10 and 11i, seid mnnuelly-contz'oiled means consisting of the push-rod 2, which is slidebly mounted in csp 2, und u lever 29 pivotlly-connectedto the iotver terminati of the push-rod and hving a hiurmited terminal 30 embracing opposite sides ci the iinnged boss 13. APushsrod 28 is normallyheld in raised position by e coil-spring 3i interposed between the head ot the push-l rod and cap 2,y Lever 29 is ulcruined upon a pin 32, extending through the lower 'terminal of irpost 33, adjustahly engaging een 2 and provided with a. lock-nut 341;, so thu it may be secured et any point of its-1erejustment. Y n

' The operation briefly stated is es follows: To start the'engine e mixture .ot gesend air is admit-ted 'thereto by operating the pushrod 28, which raises the valves 10 end i4 from their seats yand admits grusolene to lthe mixing-chamber 1 of shell 1. As the gasolee discharges from 'the upper 'end of the (portion 2O of ftubular memher 6, it iows dorm upon e conical screen 9, wherebyy it isspresd, und

is quickly generated into gas by .nir iowinp inward throughv the'inlet-ports 5.
