il l) said abutment, the extentoif the move? ment ot' the butterlly-valve D being 'regulated by manipulz'iting said adj Listing-screw, in an obvious manner. The member of Vsaid bell-crank lever is slotted so that by tightening the screw` 37, the adjusting-screw Se will .be securely locked and prevented l'rom turning.
lt designates a series of baille-plates, each of which comprises recup-shaped body, the bottom ol' which has approximately one-half o'l itssurt'ace punched out to atl'ord a. semicircular opening del, said opening el being partly closed by wire-cloth or screening lle, thereby leaving in said bottom a -emi-circular blank. These baille-plates are secured in the shell l2 and spaced apart in such inanner that the blank Al-,t3 ol the baille-plates is opposite the wire-screen Ll5 of the adjacent balllc-plates, whereby a tortuous pas age is atl'orded in the shell l2 wherein the gas and rentering the'chamber 26 and escaping l om the branch arc'thoroughly and intimately mixed.
lt is well known that the mixture of gas and air Yl'orming the explosive gas Vthat enters the motor cylinder oreylinders, is drawn into the .same by the piston therein creating a vacuum in said cylinder. lu earburctcrs as now used on internal combustion motors, there are generally provisions` made for regulating the respective volumes ot' gas and air that are admitted to the motor cyl,-
inder, some of which are hai'id-operated and" others function automaticall by the suction ol' the motor piston. ln eit ier case experience has demonstrated that the regulation ol' thel lluid and air-supply is defective when the motor is: operated under various speeds and is especially imperfect when the motor is'running at high Ispeed. Again, when a motor is shut down by closing the fuel-supply at the carlmreter, there remains in the carbureteand the intake pipe a quantity ol 'l'uel sullicient to cause the motor to turn a number olf rcvolutioiis before. Con'iing to a stop, so, that a quick stop is almost impossible. Ou the other hand, when the motor at'ter having been stopped in the manner described is to be again started, it generally has to be cranked a number of revolutions to draw in a supply or explosive fuel to fill the earbureter and Lne intake pipe before the charge-can reach. the cylinder. This drawback in entirely avoided by the intro-l duction of my auxiliary mixer and locating it near the cylinder in the intake pipe `so that very little space is left above the auxiliary mixer; and to regulate the supply of explosive fuel by manipulating the butterfiyvalve D to more or less throttle the suction of the motor pieton, said butterfly-'Valve being actuated by connecting the arm 33 thereof with any suitable means within easy reach of the operator. i
The explosive charges of gas and oxygen, after leaving the carburet'er, are generally not thoroughly mixed, and imperfect conabustion and inisfires are the necessary result. By passing these charges through my auxiliary mixer where owing to the tortuous passage therein and thealternate splitting up and reunitingl ot the charges in passing through the wire-screens, the gas and air are thoroughly and eil'ectivel-y intermixed, .l have entirely overcome this objectionable feature ot imperlect Combustion and misn tiring of the charges. i
When an automobile or launch engine et' the linternal combustion type is running t. very high speed, the suction-impulses follow each other in .such rapid Ysuccession as to practically cause a continuous iiow of gai-olene or other liquid l'nel into the carbureter7 whereby the quantity oi carbon is disproportionate to the volmne ot' air admitted. and
-imper'fect charges and misfres result theremission valve 18, by which am enabled to regulate the supply ot air by furnishing an additional supply by opening the air-admission valve by pushing upon the knob of its valvdstem, or by'automatic action cauaed h v the suction in the chamber 24S, the resistance to the opening ot' the valve 1.8 beingv regulated by manipulating the nutsl 20 and 21 to increasewn' decrease the tension of the spring 23,"iu an obvious manner; and it is a l'act that l have run an automobile at all possible speeds 'lor several hundred 'miles without a `single mislire, or having to turn the starting-crank a lter stopping, more than one. singleturn to restart the motor, this being undoubtedly due to the fact that this molor was `supplied willi my improved auxiliary mixer. j
l. have heretofore stated that the bailleplates ll have one-half of their'bottorn removed land replaced by wire-screening. 'lhis crmstruction may, however, be modified by performing one-half ot the bottom of said lmllle-plales and locating the perforated portion opposite the non-perforated portion ot the adiacent baille-platee, or I may construct-the battle-plates as il-lns'tratedin Fig. 8, by puneturing a disk 46 with a series of bustion motors, including, in combination, a casing, said easing Comprising `a shell, a. lower member on said shell, an upper inember on said shell, und :rseries of baille-plates in seid shell, there being on the lower member a radially-projecting, internally screwthreaded boss, a valveeasing removably inserted in. said boss, e valve at the inner end of said valveecasing, a valve-stem to which said valve is afixed, said valve-ste1n passing through the outer Wall of Said valvecesing,l there being air-admission openings in Said outer Wall, an adjusting nut upon said velve- Stem and in SCreKWthreeded relation thereto7 95eme a helical spring upon said valve-stein, 15
