bureters designed to be buried or located below the surface of the earth. 1

The object of the invention is to produce a carburetor of novel form and construction wherein the'air to be treated will be thoroughly impregnated with hydrocarbon vapors and delivered to points of consumption substantially free from moisture.

Another object of the invention is to pro vide a carburetor of novel form and construction occupying comparatively small space.

proportionate to its capacity and of comparatively simple and inexpensive construction. 1

A still further object of theinvention is to provide novekmeans: for se arating, condensing, and removing from --t e carbureting apparatus any moisture which may be pres ent in the air or in the hydrocarbon liquid em 'loyed.

' still further object of the invention is toprovide novel means for automatically feed mg the hydrocarbon liquid to the carburet ing a paratus. v

Ot erv ob'ects of the invention will be developed during the following description; and the invention having the above objects in view consists in the constructions, combinations, and arrangements of parts hereinafter described and claimed.

My improvements are illustrated in the accompfinying drawings, inthe several figures -my improvement.

of w chlike numerals designate correspond in parts, and in whicl igure. 1 is a vertical longitudinal sectional View of the complete apparatus constituting Fig. 2 is a vertical transverse sectional view of the same on the line a: m of Fig, 1 and Fig. 3 is avertical sectional view, on an enlarged scale, centrally of the automatic feeding appliance oi the carburetor shown in Figs. 1 and 2.

The exterior casing of the carbureter is com osed of two tanks, (designated, respective y, 1 and 2,) the tank 1 being considerabl lon er than the tank 2 and both being pre erably of cylindrical form and arranged end to end and connected by a comparatively large centrally-located pipe 3, which trates the adjacent heads of both tanks and extends a short distance within the larger tank 1. The tank 1 contains the greater part of the carbureting appliances and will be hereinafter particularly referred to as the carbureting-tank, while the tank Zc ontains the automatic feeding appliances and will be hereinafter termed the feed-tank. The head of the tank 1 farthest from the tank, 2 is formed with a hollow boss 4, within which is seated a collar 5, that serves to support a carbureting-pan 6 and a dome 7 at one end, the oppositeend of said carbureting-pan and dome being supported by the pipe 3, as

clearly shown iii-Fig. 1 ofthe drawings. The pan 6 is of rectangular form in cross-section,

while the dome 7 is'substantially semicir-- cular in cross section, having depending edges that extend towithin a short distance of the bottom of the pan, the crown of the 1 dome extending somewhat above the level of the upper edges of the pan. The dome is supported at its ends, as before mentioned, by

pens 1 the collar 5 and by the pipe 3, and it is'connectod' to the pan intermediate its ends by' stays88.

I The pan 6 and the dome 7 are inclosed in a. foraminous bag 9, which is'icomposed of any suitable material, such as burla and is supported by means of ribs or ro s 10 10, connected to the dome 7, and bysimilar ribs 'or rods 11 to the pan 6. A pipe 12 deplends' from the center of the an 6, this pipe closed at its lower end by the tank 1, and such pi e constituting a condensation-chamber an being connected by an outlet-pipe 13 with the feed-tank 2. An air-inlet pipe 14 leads from above the surface of the ground in which the carbureting apparatus is buried through the top of the tank 1 the inner wall to I and through the top of the dome 7, and said pipe 14 has on its lower end a T-coupling 15, from which extends outwardly an down wardly two curved pipes 16 16, each'of' which has onfits lower end a cup-shaped collar 17 these collars servingfito siista'in' in expanded form sponges 18, ch sponges dip into the liquid hydrocarbon contained within the tank 1, the level of such hydro carbon being shown by the dotted line H H and the spon es being almost entirely sub n1er ed in suc hydrocarbon.

T e dome 7 is separated by partitions 19 20 into three compartments, which, for

ment 22,

the sake of distinguishing them apart are designated. 21 22 23. A pipe 24 of substantially U shape connects the compartment 21 with the compartment 22 through the top of the demo 7, this pipe 21; having a funnelshaped inlet end 25 within the compartment 21 and carrying on the end that extends into the compartment 22 T-coupling 26, from which extends two outwardly and downwardly curved pipes 27 27, having on their lower ends cup-shaped collars 28 28, which carry sponges 29, such curved pipes, collars,

and sponges being similar to the curved pipes 16, collars l7, and sponges 18. A pipe 30, which is similar in ionstruction to the pipe 24 and which has funnel-shaped inlet end 31, is disposed Within the chamber 22 and carries on its opposite end, within. the chamber 23, a T-coupling 32, which latter carries outwardly and downwardly curved pipes 33 33, having on their lower ends cupshaped collars 34, that sustain sponges 35, construction and arrangement of the pipe 30, the pipes 33 33, the collars 34, and the sponges 35 being the same as that of the pipes, collars, and sponges in the compartas hereilihefore described. drainage or pump-out pipe 36 extends from near the bottom of the tank 1 to point above the ground, the purpose of this pipe being to rovide for the withdrawal of any condenser moisture that may accumulate at the bottom of the-tank 1.

A disk 37 is arranged within the tank 2 near the top thereof, and this disk is formed witha central boss 38, into which is screwed the lower end of the gas-outlet pipe 39, said gas-outlet pipe also screwing through a boss 40 in the top of the tank 2 and extending to the point of consumption. The disk 37 serves to sustain a carbureting-bag 40, this bag being com osed of similar material to the bag 9 and t 1e top ofthe same extending, as shown in Fig. 1., beneath the bottom of the gas-outlet pipe 39. The tank 2 is provided with a drainage or pump-out pipe 41, similar in arrangement and function to the drainagepipe 36 of the tank 1. A llytllpfltl'bfill-SUP- ply pipe 42 leads into the tank 2 and is connected by a T-coupling 42) and a nipple 52''to an automatically-opcrating governing-valve 44, the construction of which will be best un derstood by reference to Fig. 3 of. the drawings, to which. i will now refer. In this figure the valve and attached parts are shown onv an enlarged scale, the valve-casing being composed of an upper portion 45 and a diminished portion 46, between which portions a valve-seat 47 is formed, in which 18 seated a conical valve 48, said valve having an intogral (.lcpendin stem 49 and an attached upwardly-exteming stem 50. The valve-oasing is provided at one side with a bracket 51,

, and upon this bracket is pivoted a lever 52- by a pivot 53, said lever carrying on one end a weight 54, which Weight bears against the lower end of the depending stem 49 of the valve 48. The valve-casing carries a screwcap 51 on its upper end, which screw-cap receives the nipple 52, that in turn screws into the T-coupling 43, into which is also screwed the hydrocarbon-supply pipe s2, the oppo site end'of the T-coupling 43 receiving a solid rod 54, that screws into one branch of a crossccimling 55, the cross-coupling also re- (1 iymg a second solid rod 56, which seats in a,

means for sustaining the valve 44 and also as a means vtor guiding the stem of the float to he l'iereinalier described. Said lloat is designated 57 and is preferably in the form of a hollow cylindrical metallic vessel and is providcd with a ceiitrally-arranged tube 58, which serewthreaded to receive a screw- 'hreadcd rod 59, that extends through the cross-coupling and. through a guidingtube 60,depending from said cross-coupling, and bears at its lower end upon the upper edge of the lever52. A jam-nut 61 screws on the upper end of the rod 5.) and serves to assist in maintaining the iloat 57 at any position to which it may be adjusted on said rod. The upper portion 45 of the valvc-casing contains a spiral spring 62, upon the top of which .is arranged a perforated disk 63, through which the upper stem 50 of the valve 48 passes, thedisk as hearing against the lower end of the nipple 52 and the spring 62 being soldered to the disk and soldered to the upper surface oi the valve 48. The spring 62 ex. rts an expansive force against the valve and tends to keep the same closed, while the valve is opened, when the level of the liquid in the tank 1 falls by the weight of the iloat 57, the lever 52 being nicelybalanced by the weight 54. A stop 64 is formed integral with the bracket 51. and serves to limit the upward. movement of that end of the lever 52 upon which the rod 5.) bears.

The operation of the apparatus is as follows: A. suitable hydrocarbon liquid is admitted through the pipe 42, and the valve 4-8 being open such liquid falls into the tank 2 and rising in the same iills said tank 2 and also the pan 6 to the level indicated by the dotted line ll ll. When theliquid has reached this level, the lloat 57 has risen to such a height as to permit of the spring 62 ciosingthc valve l8 on its seat 47, thereby preventing l'urthcr ingress of hydrocarbon liquid, while the level at ll ll is maintained. When the tank 2 and the pan 6 have been charged, as above dcscrihed, air forced through the pipe 14 and passing into the curved pipes l6 l6 emerges from bclow the collars l7 and the sponges 18 in the compartment 2], partially impregmated with hydrocz-rrbon vapors, and then passes through the pipe24 and the curved l pipes 27 27 into the compartment22 and arisboss 57 in the head of the tank 2, the said rods 54 56 and the coupling 5:3 serving as a to become further enr ct tanks having i the level of the lPTlFOGflIhO-l'iliq t 11 coinpertment the s11, new heavily n hydrocarbon VLtjSOKS passes out o the last compartment 2o soroop'h the air in passing through CPL-iii not: 4.0 is caused I led with the vapor of 'ou 'h said bag the 3'01111 of an idliquid sinisi't I he gasoutiet pipe 09 i inflammable gas of snperio meis" or Water which In it-h Lhe hydrocarbon liqun;
