ASSIGNGR TO GEORGE THOMAS HINE, Gil
WESTI LINSTEB, ENGLND CABBURETER FOR INTERNAL-COMBUSTION ENGINES 0B MOTOR-S.
To all whom it may concern:
Be it known that I, An'riu'in BARKER, engineer, a subject of the King of Great Britain, and a residente't London, l lngliand, (whose posthtlice address is "20 Meads road, lVood Gret a London, England) have invented certain Improvements in Carburetors for lnternal-(omlmstion Engines or Metors of which the following is a specification.
The presei-t invention relates to carbureters or vaporizers and especially designed to provide animproved method of vaporizing; parailin or other hydrocarbons and eti'ectually combining them with the at n'iospl'ieric air so as to form a highly charged vapor i'or exploding in internal combusl ion iuigines or motors.
The oil, together with air, is drawn through a series of one or more perforated screens situated within the apparatus, and capable of apidly vibrating so that the oil becomes sprayed or atomized a. divided up into a fine state), and at the same time the air becomes :z'irbureted thereby. The intimate mixture of air and oil so termed is subsequently passed through heated paswhereby the oil become; :tully vaporized and the interlnixtnre is rendered more complete.
A particular form of construction will now be deseribed by way of example, with acctnnpanying drawings.
in the drawing vertical sectional view of a carlgnu'eter in illustrated embodying one form of my invention.
Tl'lOCflllHll'QtCl or vaporizer consists of hollow cylindrical vessel 1 of suitable .diameter and height- .titted with a valve chamber 2 preferably at the top. The latter closed by a cap 3 which serves as a means of connection to the oily or other liquid fuel supply and is provided with a seating; for the oil valve portion 4r of a duplex or compound valve around the spindle 13 of which is a sleeve 6 loosely filled said sleeve being; attached to an oil and air mixturealve T.
tached to the oil valve spindle 5 the lower end of which may rest on the top of a cap to permit of its resting on a projection 10 attached to the top ot the vaporizing or heating appliance 11. A spring 12 is 1nter- Specification of Letters Patent.

posed between the projection 10 and the top of the cap 9 and a series of gauze or like disks 13 of a diameter equal to that of the interior of the vessel 1 are suitably attached to the exterior of said cap 9.
The whole or a portion of the exhaust gases will be introdue c into the heating appliance ll tl'irough a pipe i i and will circulate. through said appliance in such a lllttl'lnor that the lower part receives more heat than the upper part. For this purpose a partition 15 may be used to more or less completely separgte the lower and upper parts. The air can be admitted to thebhrbureter through the ports at l6, l7 and 18 The port 16 comprises a series of holes bored through a neck on the valve chamber 2, and controlled by a rotatable ring 19, having holes which can be adjusted so as to either correspond-with or close the holes in said port 16. The port 18 may also be controlled by a rotatable disk 30; A shoulder 21 on the spindle 5, is slotted ve tic-ally to receive a disk 22 attached to an arm which bears against a spring Ql surrounding a rod fixed by an arm fill to the outside of the valve chamber Said spring 24; can be adjusted by nuts The disk and spring-coiiitrolled arm 23 serve to keep the valve spindle 5 normally raised and thus retain the mixture valve '7 and oil valve l. in their closed positions. During the suction of the piston, the mixture valve 7 on the spring causes the latter to bear against the collar 28, and thus lowerlhe spindle and open the oil valve 4 l certain portion oi. oil thus being admitted into the v: lve chamber 2, where it mixes with the air drawn in from one or more of the ports. The amount of suction may be regulatedby adjusting these air inlets, or by a throttle or other means fixed to the induction pipe. The oil passes through the mixture valve 7 and drops on to thelirstof the gauze disks lit a funnel 29 being provided to direct the oil. This and the other disks will durinp every suction stroke. be in a state of: very rapid vibration owing to the intermittent UOHYPFQ. on of the spring 12 during; the suction stroke. oi the piston, and the sub sequent release of said spring. This eii'eet will he gained satisfactorily even when there is a space of half'an inch or so between the spindle head and the cap 9, it not being is drawn from its seat, and pressing? 35 said means, an oil valve hav essential for the latter to support the former. The controlling action or" the spindle can be governed in some degree by means of the spring 24, which controls the disk and 5 causes the latter to close the valve 7 when the suction stroke of the engine ceases. By this means, the oil will be in a state of line division when it has passed through the gauze disks 13. It then falls on to the top msurface of the heating device 11, and passesdown through holes (preferably oblique) 1n the flanges 30, 31, 32 into the cylinder inlet chamber 33 from which it is admitted to the' cylinder. Owing to the fact that the lower 1-5 part ofsaid heating device hotter than the upper part, the heavier portions of the oil which fiow toward the.bottom are properly vaporized withoutleaving any deposit, the lighter portions being vaporizedin their assa e over the less heated unner iarts of t i l the heating chamber.
