GEORGE H. BURROVS, OF SOMERVILLE, MASSACHUSETTS.

CARBURETING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 427,832, dated May 13, 1890.

Application iiled August 2, 1888.

Serial No. 281,751. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, GEORGE H. BURROWS, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Carbureting Apparatus, of which the following is a specification.

This invention `relates to the class of carburetors in which a current of air is forced into a lioating reservoir or holder by a tromp, the water lbeing shut off to stop t-he su pply of air when the iioating holder which receives the air rises to a given point and turns onV the water to renew the air-supply when the said holder sinks to a minimum height. The air passes from the floating holder to the carbureting-chamber, where it is mixed With the hydrocarbon vapor in said chamber. A carburetor of this class is shown. in Letters Patent of the United States granted to XV. F. Burrows, No. 291,676.

The present invention has for its object to provide certain improvements relating to the details of construction of portions of the apparatus; and to this end it consists in the several improvements, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of a carburetor with my invention applied thereto. Fig. 2 is a side elevation. Fig. 3 is an enlarged detail sectional View of the water-supply valve and its operating-lever. Fig. t is a detail sectional view of the tromp. Figs. 5 and C are respectiyely front and vertical sectional views of the air-inlet valve.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the carbureting tank or chamber in which the air and the hydrocarbon vapors are mingled to form illuminating or heating gas. Air is admitted to said chamber through a pipe b from the floating holder, hereinafter described, and the resulting gas or mixture of gases and vapors is conducted from the chamber through a pipe d to the burners.

c represents an inverted tank or air-holder which iioats in water in an annular tank e. The pipe f, which admits air to the floating holder c,commi1nicates with the top of a trap .chamber g together.

or chamber g, which chamber also communicates with a vertical pipe h, having an opening h above said chamber g for the admission of air, and a nozzle t', which is supplied with water bya water-pipe i', communicating with a source of Water-supply. The pipe h and nozzle fi constitute the tromp. The downward iiow of a stream of water through the pipe 7L induces a current of air through said pipe, the air and water entering the trap or The Water escapes from the chamber g through a waste-pipe 7c, Fig. l, and the air passes from said chamber through the pipe f to t-he floating holder c.

The water-pipe t" has a valve m, which is adapted to shut off the Water from the nozzle t', the casing m of said valve having a seat on which the valve fits closely when closed. Said valve is controlled by a lever n, which is pivoted at o to a fixed support, a rod p, connected at one end to an arm on said lever, and the iioating holder c, which is connected by a chain p with the other end of said rod.

'This lever n is preferably provided with a weight n at its outer end to aid in the lowering of said lever and in retaining the valve closed. It will be seen that when Water is allowed to iiow through the nozzle t' air will be forced thereby into the holder c. When a sufficient supply of air has thus been forced into the holder c to raise the latter to its maximum height, the top of said holder, bearing against the lower end of the rod p, raises the latter, and thereby swings the lever ot to the position shown in Fig. 2, thus causing the shorter arm of saidlever to bear on a collar r on the stem s of the valve m and close said valve, as shown in Figs. 2 and 3, the chain p lying loosely on the top of the holder. The supply of Water being thus shut off, the admission of air to the holder ceases until the volume of air in the holder is so far reduced by its passage through the constantly-open pipe b into the carbureting-chamber as to cause the holder in falling to pull the lever n, through the chain p and rod p, over to the position shown in Fig. l, thereby causing the shorter arm of said lever to act on another collar r on the valve-stem s and raise the valve m, whereupon the water is again admitted to the injector, and airis forced thereby into the iioating holder c. The valve m is TOO arranged as shown in Fig. 3, so that when it is closed the Water-pressure in the pipe yi will hold it upon its seat, so that the valve eaiiiiot open until the falling holder e iiioves the lever n over, as shown iii Fig. l..

The pipe f, whie'li eondiiets the air to the iioating holder, has at its.i1iiier end an upwardly-inclined arni u, on which is adapted to slidea perforated ear o on a Cheek-valve i. Said valve, which is adapted to be seated againstI the end of the pipe f, and thus prevent the escape of air freni the holder e through said pipe, has at ils lower portion a downwardly-proj eetiiig arin r2, Which is guided by a staple-shaped guide w, attached to the pipe It will be seen that when the air is forced by the injector into the holder c the valve `r, yielding to the pressure of the air, slides upwardly on the inclined arni u, as shown in Fig. l and in dotted lilies iii Fig. 6, thus pei'- niittiiig the passage of the air into said holder. \Vhen the introduetioii of air is suspended by the shutting oii of the Water-supply, as above described, the valve yi' is seated on the end of the pipe f by gravitation, ivliieli Causes its ear fr to slide down the ineliiied arni a, aided by the back-pressure of the air. I find that this loose cheek-valve is nioie certain and reliable iii its aetion than one which is hinged, it-beiiig less liable to beeonie elogged by impurities iii the vapor and affording a wider opening when moved aii'ay from its seat.

l elainil. Iii an air-blower for earbiiretors, the eoin binatioii of a floating holder, aii air-inlet pipe opening thereinto, a troinp loeated iii said air-inlet pipe, a Water-supply pipe for the troinp provided with a regulating-valve hav ing an upwardly-projeet-ing stein fitted with upper and lower Collars, a lever having' one eiid engaging said collars, its other end being Weighted, and a connection between said lever and the floating holder, substantially as set forth.

2. In an air-blowerforearbiiretors, the eenibiiiatioii el a floating holder, a troinp, an.

Aair-iiilet pipe opening into said holder and provided with an inclined arm, and a sliding' valve adapted to nieve on said arm, siibstaii tially as set forth, said tronip being located in said air-inlet pipe, as stated.

In testimony whereof I have signed my naine to this specification, in the presence of two subscribing witnesses, this 30th day of July, A. I). 1888.
