GARBURETER.

Specification of Letters Patent.

Patented J une 11, 1907.

Application lled June 29. 1905, Serial 110.267,674.

To all whom it may concern.-

Be it-known that we, THOMAS MCCORMICK and ANAN-ms MILLER, citizens ot the United States, residingy at Mount Pleasant, in the county of l/Vestmoreland and State of Pennsylvania, have invented a new and useful Carbureter, of which the following is a speci- 3 fication.- i

This invention-relates to improvements in xo means for supplying charges ofinotive luid to explosion engines.

One of the principal objects is to provide a novel and excecc ingly simple structure, wherein the hydrocarbon or other fluid emr 5 ployed will be thoroughly vaporized, only as rapidly as required by the engine, and is delivered to the engine or explosion chamber thereof in propercondition to be exploded, theapparatus operating with a high degree 2o of e'lliciency and economy.

Affurther and important object is to provide a carbureter fromfwhich a plurality or battery of engines can be supplied withfmotive fluid, each engine being operable without re ard to the condition or relation of any ot er connected to the carbureter.

The referred embodiment of' the invention is i lustrated in the accompanying drawings, wherein: t

3o Figure1 1s a vertical longitudinal sectional view through the new carbureter. Fig. 2 is a horizontal sectional view on the-line 2--2 of Fig. 1. Fig. 3 is a crossI sectional view on the line 3 3 of Fig. 1. Fig. 4 is a top plan view of the upper perforat-e partition.

Similar .reference numerals designate correspending parts in all the figures of the draw` ings. l i

In the embodiment illustrated, a casing is 4o employed comprising a bottom 5, side walls 6, end walls 7, and a top 8. Interior upright walls 9 divide thc casing into outer mixing chambers 10, and an intermediate vaporizing chamber, the latter of which has a detach- 4 5 able cover 1l, comprising a section of the top 8, that bears upon the upper edges of the walls 9, and is packed by a suitable gasket 12, the cover being fastened` in place by any suitable in yins, as, for instance, bolts 13.

5o' The cai rating chamber has extending across :its per and lower portions, partitions .te and l5, spaced apart, the upper parthe tube 19.

tition 14 being spaced from the cover 11 and forming therewith an air coi'npartment 16. The lower partition 15 is spaced from the bottom 5, forming a vapor compartment 17, which compartment 1s in communication with the mixing chambers 10, by means of perforations 18, formed in the interior walls 9, below the partition 15. A perforated tube 19, preferably rectangular in cross section, as illustrated in Figs. 2 and 4, has an open lower end in communication with the vapor comartment 17, thc perforations comnnlnicatmg with the space between the partitions 14 and 15. The interior of the tube is cut 0H from communication with the air chamber 16, referably by extending the upper end of saidp tube to the cover 11 ot' the vaporizing chamber. A body ol absorbent hydrocarbon-holding material 20, is interposed between the partitions 14 and 15 and surrounds This material may be anything suitable for the purpose, such as asbestos, waste, or the like.` The upper partition is provided in its upper side with a hydrocarbon-receiving channel 2l., extending about the tube 19, said partition having perforations r22, located on opposite sides of the channel. The lower partition 15 is also provided with perforations 23. The cover 11 has a suitable supply opening 24, which may be closed by a plug, as 125.

The air compartment 16 of the vaporizing chamber has through its cover an air inlet opening 26, closed by an inwardly o )cning check-valve 27, which valve is normally held closed by a spring 28, one end of the spring bearing on. a yoke 29, bridging the opening, the other end of the spring bearino against a nut 30, threaded upon the stem ol the valve and adjustable to vary the resistance to the opening movement of said valve. The mixing chambers 10 are, in like manner, provided with air inlet openings 30, controlled by valves 3l, similar in all respects to the valve of the-'air chamber. Leading from the mixing chambers are pipes 32, which pipes may be connected` to separate engines, valves 33 being preferably located in said pipes to control the passage of the motive fluid therethrough.

y In charging the carburetor, the plug 25 is removed and the hydrocarbon or other suit TOO able liquid is poured through the same into the channel 2l, It will be seen that said channel will be completely filled and consequently, when it overows, such overflow will take place on all sides, so that ythe fluid will be distributed equally over the body of absorbent material, thus obviating the danger of saturating one portion of the body prior to another portion. This `is an important feature of the invention. The body ot absorbent material having been thoronghly saturated, the supply opening 24'is again closed by the plug, and the valves 33 of the delivery pipes 32 are opened. As the engines are turned, it will be apparent that suction will take place through the pipes 32,'

i exploded is delivered from the carbureters to the engines and is manufactured and supplied only as rapidly as the engines require, depending on the speed thereof. The richness, of the mixture can be v'varied to suit the conditions of work by altering the resistance to the dierent inlet-controlling valves. Thus, by weakening the resistance to` the valve 27 and strengthening the resistance against quently two engines can be operated by the the valves 3i, the vapor supplied to the engine can -be as highly charged with hydrocarbon as desired. 'On the other hand, if the resistance against the opening of the valve 27 is made comparatively great and the spring action on the valves 31 is weakened, the reverse will take place. The structure, moreover, is exceedingly simple and can be manutactured at comparatively small cost. Furthermore, there is no thing that is liable to become inoperative or deranged, and the device, being compact, will occupy but little room, making it useful, particularly in cramped or confined places, such as automobiles. It will thus be seen that the carbu-- reter disclosed is not only highly eflicient, but economical in operation, and that a plurality or battery of engines can be run from l the same without in any manner interfering. `While two mixing chambers, and conseprescnt device, it will be evident that a greater or less number of mixing chambers, and consequently of nes, can be connected to the vaporizing chamber and the structure stili be enti l f eilicient.

il om the foregoing itis thought that the construction, operation, and many advanatacar tages of the herein described invention will be apparent to those skilled in the art, Without i'urther description, and it will be understood that various changes 1n the size, shape, proportion, and minor details of vconstruction may be resorted to without departing from the spirit or sacriiicing any of the advantages o the invention.
