AcE'rYLElaE-GAS c. ENRATOR.

SPECIFICATION forming part of Letters Patent No. 723,411, dated March 24, 190s.

Application filed .Tune 18, 1902.

Gas Generators; and I do hereby declare the t following to be a full, clear, and exact description of the invention, such as Will enable othi ers skilled in the art to which it appertains to anake and use the same.

This invention relates to improvements in :acetylene-gas generators; and some of the objects of my improvements are, first,'to pro-y vide a gas-making appara-tus economically constructed and easily operated; second, toI

.afford means for automatically eq ualizing the pressure in the generator and in the holder; f third, to produce means for increasing and 'decreasing the feeding ofV material from which lthe gas is evolved; fourth, to construct a device for preventing fluctuation of the gas in the gas-holder, and, fifth, to connect the gen- Ierator and holder together andy at the same time provide a passage between the same. I

attain these and other objectsby the constru-c- .l tion illustrated in the accompany-ing draw-y 1 cushion 9 and is inserted and securely fas- Figure 1 is a view in elevation of the generator and gasometer, parts thereof -in section y and parts of the same broken away. Fig. 2 is -a view in lelevation of the invertedthimble,` and a yportion of the supporting gas-pipe, and 4*guide-rod for the thimble.

Fig. 3 is a longiitudinal sectional view of the inverted thimble, thesupporting. gas-pipe, also shown in` section, and a-portion ofthe guide-rod, shown 4in elevation.

Fig. 4c is a detailed View showing a portion of the hopper, upper portion of the generator, carbid-valve, and guide-pipe lpartly in section, and guide-rod in elevation;

-and Fig. 5 is.a.detailed view illustrating a -portion of the carbid-hopper,- upper portion of the generator in section, the carbid-valve,

guide-pipe, and guide-rod in elevation.

Similar reference-numerals refer to like parts throughout the several views.

The numeral 1 refers to the generator.

' 2 is the holder or gasometer. The casting secured to the hopper 2O by means of screwbolts or rivets or other suitable devices, is in like manner fastened to the casting y, riveted -Serial No. 112,241. (No modell.)

or bolted to the top or dome 4 of the generator 1, and the said casting m has an opening therein snfciently large to admit the valve 25 therethrough before said casting c is fastened'to the casting y, riveted to the dome of the generator.. The said holder 2 consists of the outside tank 13 and the inside inverted tank or cooler 14, employed to wash and purify the gas evolved from carbid or othergasmaking material, which is conducted from the generator 1 through the connecting-pipe 3, the saidV pipe securely inserted at one end thereof into the top or cover 4 of the genera! tor and extending laterally, then downwardly, and istinserted into theroutside tank 13,-near the bottom thereof, and extends upward within the holder or gasometer above the waterline 7 thereof.

I invert a thirnble 8, which has fixed in the closed end thereof a leather valve or cushion 9, which thimble rests directly upon the upper projecting end of the gas-pipe 3 in the gasometer above the water-line, and the said thimble is held in place upon the free open end of said pipe 3 by means ofthe guide-rod 10. This inverted thimble 8 has a guide-rod 10, which passes through the leather valve or .tened into the upper or closed end 11 thereof. Said rod 10 projects downwardly into the pipe-3 within the gasometer o'rholder 2 and acts asa guide to retain `the'thimble 8 in the proper position upon the open end of the said pipe 3, thereby preventing the thimble 8 from being displaced by the evolved gas passing from the generator 1 through the connecting-pipe 3, connected to the top or cover of the generator l above the water-line 5 therein, into the .gasometerl holder. This thimble 8 deliects the gas above the water-V line 7 Within the thimble downward into the water within the gasometer orholder 2, and finally the said gas makes its exit through a number of perforations 12 near the lower edge of the thimble into the water in the cooler or purifier and is again washed in its passage upward through the water to the top of the holder 2, above the water-line 7 thereof.

In the top of the generator 1 I secure a pipe 15, which extends nearly to the ,bottom of the',`

generator. I insert through the said pipe 15 a rod 16, referred to as an agitator or stir- IOO rer, bent at right angles upon itself, near the upper and lower ends thereof, and in opposite direction from the body portion. The said rod or stirrer 16 within thegenerator is designed to agitate and thoroughly mix the precipitated material at the bottom of the generator not taken up by the water contained within the or plated in order to prevent oxidation of the same.

20 is the carbid-hopper, preferably made in the iorm shown upon the drawings. At the apex thereof is a screw-threaded plug 2l, through which the carbid or material used in manufacturing the gas is poured. The hopper 20 has a partition therein, 22, extending entirely around the hopper, except at the lower portion thereof. This partition 22 divides the hopper into two compartments 23 and 24, in the upper of which, 23, the carbid material is retained, while the carbid-valve 25 is located in its seat. The lower compartment 24 provides space for the upward and downward movementof the carbid-valve 25. The upward movement of said carbid-valve 25 by means of the lever and operating-rods permits the carbid Within the upper compartment 23 to pass around the lower edge of the partition 22, thence downward around the inclined portion of the lower side of the hopper, thence into the generator, when the carbid-valve 25 is unseated, as shown in Figs. 1 and of the drawings.

The rod 27, surrounded by the pipe 28 in the generator 1, is held in position in the lower tapering end of the carbid-valve. The pipe 28 is suitably secured in the lower tapering end of the carbid-valve 25 by solder or other means. Said pipe extends nearly to the bottom of the generator. The rod 27, at the lower end thereof, is pivoted to one end of the lever 29, which is fulcrumed or pivoted between two upward projections secured to the bottom of the outer tank 13 of the gasometer or holder 2. Said lever 29 extends through the communicating passage 6, which connect-s the walls of the outer tank 13 and the generator 1, whereby the Water or liquid in the outer tank 13 and that contained in the .generator 1 circulates back and forth. Through the said communicating passage 6 the said lever 29 extends from tank 13 to the generator 1. Said lever fulcrnmed near the bottom of the outer tank 13 is pivoted at the end thereof within the outer tank 13 to the rod 30, which extends upward from near the bottom of said tank 13 to the top or cover of the inverted tank 14 of the gasometer or holder and projects slightly through the apex ofthe inverted tank 14. Said rod 30 has surrounding the same atube 31, securely fastened, by means of screw-threads or other means, to the dome of said inverted tank 14. I secure, by means of screw-threads or other suitable devices, the cap 33 upon the projecting annular flange 32, secured to the dome of the inverted cover 14, in order to protect the end of the rod 30, which slightly projects above the top of the apex of the dome of the inverted tank 14 and above the annular ange 32, secured to saidV apex.

` When it is desirable to remove or elevate the carbid-valve from its seat in the mouth 'of the generator 1 in order to permitlthe carbid Withinthe compartment 23 to slide down the inclined passage-way to the mouth of the generator and into the same, I remove the cap 33 from the annular tiange 32, and by slight pressure upon the end of the rod 30 the carbid-valve 25 is elevated within the compartment 24 of the hopper, and the carbid readily passes into the generator 1. When suicient carbid has passed into the generator, I remove the pressure from the end of the rod 30 and replace the cap 33 upon the annular flange 32, which then regulates the feeding of the carbid within the generator 1.

The gas which has been'generated and conveyed from the generator 1 through the pipe 3 into the inverted tank 14 and purified by means of the water contained in the outer tank 13 is ready to be conveyed by means of the pipe 34, one end of which extends above the water-line 7. The opposite end of said pipe projects through the lower wall near the bottom of the outer tank 13. To this pipe, at its outer projecting end, gas-pipes may be connected in any ordinary or usual manner and through which the gas manufactured may be conveyed to dwellings of any kind where an economical light is desired.

A further description ot' the mode of oper ation of my invention is not necessary in view of the above description, when taken in connection with the drawings hereto appended and made a part of this application.
