fili

chamberu rl`he oil will also be thoroughly and uniformly volatilized by the compara.- tively small gage of the spouts 2l.

lntegrally formed with the cylinder 18, at the lower end thereof, are inwardly projecting; radial spokes BO supporting an internally threaded hub 3l into which is cured a screw bolt o2 threaded at its upper and lover ends and plain therebetween. A nut 33 is provided on the lower threaded end of thc bolt 32, by'means ot' which the air tlue 34- and a cage 35 are tightened to the carliuireter body l5, as may clearly be seen in Fig. l. The cage 35 is Inovided with holes 36 and is surrounded by a cupshaped shutter 37 endinr in a tubular (.low-nward projection 3S which rests slid ably on the top surface of the nut 33. The shutter is provided with holes adapted to register with those ot the cage 35, and to shut them partly or .entirely by turning the shutter around, for which purpose it is provided with a handle 89. The admittance ot' air Yfrom the air tlue into the cage may thusl be obviously regulated by the shutter 37.

.ln the cage 3:7 is formed a valve seat 40 into which lits a tapering, hollow valve il slidably 'mounted on the bolt 32 by means of a sleeve 42. lt is held on its seat by a coil spring the upper end of which is conned by a. shouldered nut 44 held firmly in position on the upper threaded end of the bolt 32 by a pin 45, whereas the lower end of the spring 4B rests on. the bottom of the valve .t. The tension of the spring` 43 may be regulated by turning the bolt 32 which latter is locked in the desired position by the nut This nut thus serves 'for two distinctly ditterent purposes.

lt will be. understood that when the valve open and the engine connected to the carburetor is started` a suction by the former takes place and creates a vacuum in the latter, whereby the valve 4l will be raised from its seat in opposition to the spring thus admitting' air from the lower part ot the cage The oil supply will automati cally be regulated by the extent of opening the -`valve 25 connected to and actingr upon the slide valve 26 which thus opens up a corresponding number ot spouts 2l, and the air supply, the required proportion ot' which may be deermined by the tension of the spring 43 andby the shutter 37, will be regulated by these two factors, so that the desired quantity and proportion of oil and air may be ted, to the engine, thoroughly mixed and' Volatilized by the symmetrically 'distributed and c-,omliaratively small gage spouts 21, as also on account of the heating,f of the interior of the carbureter.

ln. the modified form of embodiment ot the invention shown in Fig. 2, in which the air fine has been omit-ted, the connection between the Valves 25 and 526 has been elimimais@ r nated and the latter is connected, instead, to the valve itl by.' means ot vertical rods 4G, as shown. increase ot the oil supply is attained by an upward movelmeut ot' the slide valve QG, as

21.itlinst the downward movement thereot' iu the first described t'orm of embodiment and, consequently, the iowermost spouts 2l are partly uncovered by the valve 2G in the closed position shown in The number of spouts l uncovered is, also in this 'form` auton'raticaily, although indirectly governed by the extent ot' opening of the valve 25, by means ot the amount of vacuum resulting;` in the carburetingcliamber of the carburetor, which controls the extent of rise of the valve 41 trom its seat and thereby the extent of movement oi the sliding valve The bolt 32 is, in this `torni, substituted by ay tube. ti', screwed into the hub lll and provided, at its lower end, with an outwardly projecting Hange i7 which supports and secures in place the cage Un it rests, too, the shutter 37.

'lhe upper cud of the tube #t7 is provided with fou r equidistant longitudinal slots serving` as guides :tor au equal number ot lugs 4S formed near the upper end of a rod 49 slidably mounted in the tube 4:7 and protruding out of the lower end thereof. A plug1 50 is inserted in the upper end ot' the tube l? as a reinforcement to counter-balance i the weakening eii'ect` of the slots beforementioned.

rllhe springh i-I3 i around the tube l lugs 48.

@n the piotrudinglower end of the plunger 128 is coiled another spring 5l, weaker, but normally under higher tension than the spring which latter, in the closed position of the valve 4l, shown in Figs. l and 2, is practically fully expanded. The spring 5l is held under tension between the bottom surface ot the 1(lange i?" and a cup 52 on the lower threaded end of the rod 4S and locked in the desired position by a nut rlhe suction of the engine will thus rst act on the weaker spring 5l, until the limit is reached by the contact of the upper edge of the cup 52 with the bottom surface of the flange 47 and, with a. constant moderate suction, this position of the parts described Will remain fairly steady, thus practically eliminating the vibration ot the air admission valve usually obtaining insimilar devices. lVhen the suction' is considerably increased, the spring- 43. will come into play, shutting the valve down to normal as soon as the strenger suction ceases. thus attordingr a. perfect automatic control ot the ail admission by the uuu'iiuilation ot the valve 9,5

and the sneed o" the engine.

will be seen 1u liig. EZ, the cylinder i8 s, in this form, coiled T and confined by the ln this :form oi embodiment, thel is, in this form, substituted by a triple cylinder consisting@r ot a cylindrical downward projection 5l ot' the bodyY lf3 itself. a metallic reinforcing core iiinide ot' the projection 5l, integral with the spokes Zit). and a lining 56 of the same material as the body l5. inside ot' the reinforcing eorc 55, all iii close contact with and conveniently secured to each other. In this modification the duets 19, instead of being bored in the cylinder, ai'c molded into the downward projection 54, as at 5T. The. spouts 2l are formed b v oblique bores throuzgii the walls oi the, core 55 and the lining 5G, at coriesi'ionding points. thus doing away with thepliigging.

The second modification of our device, shown in Figs. 5-7, in which the air flue has been omitted, embodies the saine gen eral features of construction and arrangenient which are employed in the 'toi-m Shown in Fig, 2. However, in this modification the shutter 37 is arranged inside of the cage with such minor constructional changes as aro involved by thin arrangement and clearly shown in Figs. 5 and 7. @ne of these {,-hanges is a slot 58 made inone side of a hole 8o of the cage 35 (Fig. 7) to admit therein thc handle 3f) oi' the shutter 257 when the latter entirely uncovers the holebiv 3G. The shutter 37 has, in its center, an upwardly projecting sleeve 59 provided, at one portion of its` top edge, with a cam 60, a similar rain 6l being' formed on the bottoni Surface of the valve 41. These cama are arranged to cooperate, when the shutter is'in fully closed position, as on starting, in holding the valve 41 in a Slightly elevated position` and, through the intermediary of said valve, in holdingv the Sliding valve Q6 in a slightly ele 'ated position whereby the lowermost spouts 2l will be uncovered and open to the carbureting chamber.

To overcome the torsioiial Strain on the vaire-roda 46 when the cams thus act against each other, tlieyjare `guided through holes 62 provided in the spokes $30. As may be seen in Fig. l5, the valve 41 is in this form also made of the saine material as the body l5.

It must be understood that each ot' the various riiodicatioiis of certain features of our invention shown and described may be interchanged and combined in any form of embodiment of our invention and any further alterations and modifications may be resorted to without departing from the principles as set forth iii the claims here.- uiito annexed.
