ACETYLENE-GAS-GENERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 609,673, dated August 23, 1898.

Application iiled March 3l, 1898.

To all whom it may concern:

Be it known that we, JAMES T. HAYS and THOMAS C. HAYS, citizens of the United States, residing at Emmitsburg, in the county of Frederick and State of Maryland, have invented certain new and useful Improvements in AcetyleneGas Apparatus, of which the following is a specification, reference being'had therein to the accompanying drawings, in which- Figure l represents avertical sectional view of our apparatus, and Fig. 2 a transverse detail section of the retort containing the carbidcompartments.

The invention is designed to simplify and improve apparatus of this sort, rendering it safer and more eifectual in operation, as more fully hereinafter set forth.V

Referring to the drawings by letters, a designates the vertically-movable part or bell of the gasometer; b, the lower part of the gasometer, this lower part having double walls inclosing a suitable sealing liquid, and c the outlet-pipe for the gas.

The retort b', containing the carbid-boxes, is fastened transversely of the bottom of the gasometer and is connected by a pipe d with, the gas-space of the same, said pipe extend-` ing in through the walls of the lower section of the gasolneter and up through the liquid contained in the lower part thereof, said pipe CZ being provided with a valve or cock d at a suitable point outside of the gasometer, whereby communication between the carbid-boxes and the gasometer may be shut off. A suitable flling-pipe 'e is connected through the bottom of the gasometer with the liquid-space therein. f

In the retort b', the head of which is made easily removable, so that the carbid may be renewed readily, are located two or more trays or boxes f, which are supported one above the other and are endwise and separately removable irom the retorts. These trays are divided transversely into a series of compartments, the partitions being solid, so that the compartments will be water-tight from each other, the partitions, however, terminating below the upper edges of the trays, so that when one compartment is filled with water Serial No. 675,963. (No model.)

ometer) to the gas-inlet pipe el is a lateral pipe t'. Extending down through tube h is a rod j, which is provided at its lower extremity with a valve 71:, which is normally closed against seat h by means of a suitable spring Z at the upper end of rod j or by means of a iioat attached to rod j below valve 7c, as shown at m in dotted lines, or by any othersuitable devices. Another valve n is fastened to rod 'y' at a point above pipe Q1 and is adapted toclose down upon a'valve-seat n', formed in tube h at a point below said pipe t', said valve n, as is evident, lying nor- Inally above said lateral pipe z', so as not to interfere with the flow of water therethrough. A tappet 0 is attached to the top of the bell a, directly over the rod j, so that when said bell falls a predetermined distance the tappet will strike upon and depress said rod j and open the valve k and let wat-er flow into the carbid-boxes.

It will be observed that the apparatus is entirely "automatic in action. As soon as a sufficient quantity of water is discharged into the carbid-box the generation of gas lifts the bell and allows valve 7o to close. Should suiicient gas be generated to endanger the apparatus, the surplus will escape through pipe p, which extends up through the sealing liquid between the walls of the gasometer to above the level of said liquid, its upper end communicating with the gas-space of the gasometer.

pipe p is closed by a tube q, which depends from the upper end of the movable part a 4and extends down into the sealing liquid to a point a little above the lower edge of said bell o, the upper end of tube q being closed.

The upper open end of IOO It will be observed that the tube q will passv out of the liquid and uncoverl the Aupper end` of tube q at a predetermined point and thereby permit any surplus gas to escape without blowing off the top of the gasometer.

It will be observed that as the liquid passes down through pipe CZ into the carbid-receptacles the generated gas will pass up through said pipe and be thereby cooled. If it is desired to cool the gas still further, the portion of pipe d above pipe i may be removed, so that all the gas will be compelled to pass through said pipe c' and up throughv tube h. It will be observed that` the carbid in the trays will be consumed in sections, beginning with the front compartment in the upper box,

then the next compartment therein, and so on, the liquid passing through pipe g to the rear compartment of the lower tray when the carbid in the rear compartment of the upper tray is consumed. Any number of superposed trays may be employed, as is evident. In this manner the unconsumed carbid is kept comparatively fresh until ready for immediate use.

' It will be observed that should the bell of the gasometer fall to a predetermined point after all the carbid is consumed the valve 'n will seat itself upon seat n and be held thereon by the pressure of the bell, and thereby prevent the tank from emptying itself through or into the carbid-retort, and should valve d be inadvertently left closed,thereby preventing opening valve r, which is in the form of a tube,l

and normally rests upon and closes the upper end of pipe r, thereby avoiding all danger of explosion in the carbid-receptacle.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

In a gas apparatus, the combination of a gas-holder consisting of Aan upper movable part or bell and a liquid-tank, a carbid-holder in communication with said gas-holder and the liquid-tank, a tube supported in the gasholder and dependinginto the liquid and having its lower end open and provided with valve-seats h and n', a lateral branch pipe connected at one end to said tube and communicating at its other end with the carbidholder, a valve-rod extending down through said tube and provided with a valve 7c at its lower end adapted to close upon the aforesaid valve-seat 7L', means actuated independently of the movable part of the gas-holder for normally closing said Valve k up against its seat, means whereby said valve-rod is depressed and valve lc forced away from its seat when the movable part of the gas-holder falls, a supplemental valve n attached to the valverod above the branch-pipe connection and adapted to seat itself against said valve-seat n in the tube below the branch-pipe connection whenthe movable part of the gas-holder falls a predetermined distance, substantially as set forth.

In testimony whereof We hereunto aflix our signatures, in the presence of two witnesses, this 28th day of March, 1898.

JAMES T. HAYS. THOMAS C. HAYS.
