CARBURETING DEVICE.

specification of Letters Patent,

' Patented Oct. 13, 1908.

Application filed. May 9, 1906. Serial No. 316,019.

To all whom it may concern:

Be it known that I, AIMii CLEMENT GRA- NEL, a citizen of the French Repubhc, residing at St. Cloud, in the Province of Seinesheath of gelatin or other suitable material,

that is to say, a material which will withstand the action of hydrocarbons, and t con tains an absorbent and permeable llgneous body soaked with the hydrocarbon which it is desired to employ.

The cartridge or small carbureter is contained in the handle of the instrument which may be ofmetal or other material which will withstand the action of hydrocarbons, alcohol, ether and the like.

The accompanying drawing illustrates, by

wayof example, the application of the sys;

tem to a thermo-ca uterizer. V Figure 1 1s a vertlcal section of the instrument; Fig. 2 is a longitudinal section of a modification of the same; Fig.3 shows a carbureting cartridge detached in elevation; Fig. tis an elevation partly. in section of the cock of the saidmodification; and Fig 5 is a plan showing the arrangement which allows of turningthe plug'of this cook. a

The handle of the instrument consists of two parts: the body ca-containing the carbureting cartridge Z) and the head 0 which carries the burner B.

The cartridge 2) introduced into the body a of the handle rests with one of its ends upon a plug e of soft and permeablematerial forming a cushion while allowing the air which is blown into the instrument to filter through. i

The head 0 is provided with a shoulder f serving as a support for an indiarubber washer g which caps the other end of the cartridge and forms a hermetic joint between the body and the head of the handle of the instrument.

pencil for pyrography, for ex- At the lower part of the body a is a nozzle it provided with a cock 2', and which serves to receive the end of a tube connected with an air compressing bulb or other suitable compressor.

The head a, which is separated from the body of the handle by the indiarubber washer 9, forms a chamber into which enters the carbureting air to be sent through a passage 1' to a passage 0 in a cock 7c, the plug of which is moreover provided with a passage m to which extends a small tube at, the other end of which is connected with the interior of the body ('1 containing the carbureting cartridge.

.The two passages m and 0 in the plug of the cock is are bored at a right angle to one another so that according to. the position of the said plug its passages more or less uncover the tube j and the tube a at the same time. I

The instrument is assembled in the following manner: The head 0 is unscrewed in order to uncover the upper mouth of the.

body a of the handle, and in this handle is placed the carbureting cartridge Z) previously perforated at each of its ends; it rests with'its lower'part upon the permeable plug 0, the head 0 is replaced in position and the .indiarubber washer Q then caps the cartridge, forming a tight joint between the two compartments a and c of the handle;

the upper part of the cartridge projects into the upper compartment formed by the head. Thecock- 7c beingin the proper position, air is blown in through the nozzle h, the air passes through the plug 6 and part of it becomes compressed in the body of the handle while the other part passes through the cartridge as indicated by the arrows in Fig.1.

The air which is carbureted in its passage through the cartridge 6 enters the head 0 of the handle and passes through the passageo 1n the cock, while the compresesd air in the lower part'or bodypasses through the tube a to the other passage m.

The carbureted air passing through 0 and the uncarbureted air which passes through m become mixed in the chamber 7) above the cook 70 and thence pass to the burner. It will be understood that according to the position of the plug is the passages m and 0 will be moreor less open so as to allow of varying the proportions of the combustible mixture; these passages being at right angles to each other the proportions of car bureting and uncarbureting air vary inversely; a mixture of a given richness can therefore be obtained.

In the arrangement shown in Fig. 2 the mixture of carbureted and unearbureted air takes place in the cock itself and the eartridge is pressed towards its upper cap by a spring which insures a sufliciently tight joint for preventing the mixture of the air passing into the cartridge and the air passing around the said cartridge.

The head 0 is screwed on to the handle (1. and a milled flange (Z which is provided on the head, not only serves as a stop to limit the movement of the head, but also serves in conjunction with the washer g, as an effectual means for hermetically closing the joint between the cartridge within the bandle a, and the head. \Vithin this casing, at the lower part, is a cap 9 which is employed instead of the indiarubber washer or cap 9 of the preceding arrangement; this cap is of the same shape as the end of the cartridge 6 which is pressed against the cap by a spring r placed in the lower part of the handle a. I prefer to interpose between the spring 1', and the lower end of the cartridge 1), a cup 41, which serves as a substantial retainer for that end of the cartridge. The cup is, of course, perforated to register with the open ing in the cartridge.

The head 0 is provided with the cock Z: which has only one passage 0. This passage 0 is enlarged at one end to allow of it comi'nunicating with the two passages j and 12, one for the carbureted air and the other for unearbureted air. By operating the plug by means of its forked handle 9 one of the passages j and n can be more or less opened, thus regulating the inlet of carbureted and uncarbureted air.

The head 0 is provided with an extension or stem 3 upon which is placed a socket 25 preferably of lignum vitae surmounted by several washers a of asbestos or other insu lating material held in position by means of bolts 5 which bear upon washers 00, m

he washer 02 has an extension 1 in the form of a socket screw-threaded internally to receive the burner.

It will be observed that the handle 9 which I? serves to operate the cock is is preferably in the form of a fork, the prongs of which are applied (see Fig. against the two ends of the plug of the cock. On the side of smallest diameter (in this instance, tllU left-hand side of Fig. at) the prong of the fork serves, in conjunction with the screw .27, to prevent the plug from coming out of its shell.

heircompressed air is caused to enter through the nozzle 71 part of the said air passes into the cartridge whence it issues in a carbureted state through the upper hole and the pa. The other part of the compressed a 1' passes into the annular space provided between the cartridge and the handle and out through the passage 11.

The carbureted and uncmrbureted air thus become mixed in the passage 0 ol the cock K. The admission of the (.zll'llllltlttl and unearbureted air is regulated by turning the plug of the cock by means of the handle Q and one of the passages or n, is more or less obstructed. The coinlnistible mixture thus reaches the passage 0 whence. it passes to the burner.

For certain uses, particularly for luminous projections, and for soldering lamps, oxygen instead of air may be passed into the apparatus.

Having now particularly described and ascertained the nature ()fl my said invention and in what manner the same is to be performed, I declare that what I claim is:

l. A carbureting device comprising :1 casing with an outlet, a cartridge insertible in the casing and adapted to be pressed against said outlet and having a passage adapted l'or comnumieation with the outlet when so pressed, and yielding means carried by the asing and engageable with the cartridge to hold the same pressed against said out let.

2. it carbureting device comprising a casing having a cap with an outlet, a cartridge insertible in the casing, with one end adapted for insertion within said cap and having a passage adapted for communication with the outlet, and a spring carried by the casing and engag able with the other end of the cartridge, whereby it. held within the cap and pressed against the outlet therein.

In witness whereof I have hereunto signed my name this 26 day of April 1906, in the presence of two subscribing witnesses.
