PATENT ACETYLEN E-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 626,437, dated June 6, 1899.

' Application filed March 20, 1899.

To (all whom it may concern:

Be it known that I, LABAZURE O. MOLANE, a citizen of the United States, residing at Linesville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Acetylene- Gas Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in acetylenegas generators; and it consists, substantially, in the improvements in the mechanism thereof hereinafter set forth and explained, and illustrated in the accompanying drawings, in which Figure l is a front view in elevation of my improved acetylene-gas generator with one of the carbid-holders in section. Fig. 2 is a side view of the same, partially in elevation and partially in section. Fig. 3 is a top or plan view of the same. Fig. tis a sectional detail view of a portion of the same. Fig. 5 is a horizontal section of the water-supply valve, showing features of its construction.

, In the drawings thus illustrating my invention, A is the tank, in which the gas-holder B operates, and is provided with a gas-inlet pipe at, a gas-outlet or service pipe a, and a -waste-pipe 0. all of ordinary construction.

The gas-inlet pipe ct is also provided outside of the tank A with a drip-tank b, and servicepipe a is likewise provided with a drip-tank Z), the arrangement and location of these driptanks 1) and I) being clearly shown in Fig. 2.

At one side of the tank A are placed two carbid-holders O and D, connected with the inlet-pipe Ct by a cross-pipe E, provided with shut-off cocks e and e, so that either one of the carbid-holders O and D can be shut off when desired. These carbid-holders are constructed with double walls D D so that there is an annular space (Z between them. This annular space d is wider at one side than the other, so as to admit an arm E of the pipe E to extend up between them. The space cl is adapted to be filled with water nearly to the Serial No. 709,750. (No model.)

top of the pipe E. Within the inner wall D I place a pail F, provided with a bail (not shown) for conveniently lifting and carrying it, and within the pail F, I placea removable circular screen F,within which the carbid is placed. For closing the top of the carbidholder I use a cover G, provided with an annular rim G, which extends down some distance into the water in the space d, so as to form a complete water seal, as clearly shown in Fig. 1. On the top of the cover G there is a space 9, adapted to hold water, so that the carbid is surrounded at the sides and top by water for cooling purposes. In the top of the cover G'is secured a trapped water-inlet H, provided at the bottom with a sprinkler hfor distributing the water over the carbid in the pail F, and at the top with a funnel h, into which the water is supplied. The cover G is also provided with a cock 9' for allowing any gas remaining in the carbid-holder to escape before the cover G is removed. The carbidholders are also provided with swinging hooks 01, adapted to engage the top G and hold the same in place.

For supplying the necessary water to the carbid-holders C and D there is a pipe I extending out from the tank A some distance above and midway between the carbid-hold ers O and D. On the end of this pipe I, I place a three-way cock J, and to the upper outlet J of this cock is connected a pipe I, leading to the bottom of a small tank K, and from the lower outlet J of this valve is secured an elbow l, in which is pivoted a pipe L, adapted to swing, as illustrated in Fig. 1, so as to convey water from said cock J to either of the carbid-holders O and D, as desired.

The valve J is provided at its inlet side with two passages j and j, as illustrated in Fig. 5, and the plug J 3 is provided with a small diagonal passage j adapted to communicate with the passage j only when the plug J 3 is turned to a certain position, while the main passages 7' and 9' in the plug communicate, when the plug is properly turned, with the regular passages j, 7' and j of the valve, as and for the purpose hereinafter explained.

For operating the Valve-plug J 3 there is a lever M, provided with a weight M, and there is a ring m on the end of the lever M. There is also an arm N secured to the plug J adapted to engage a stop it, so as to limit the downward movement of the lever M. On the top of the tank A there is an upright post 0, provided at its upper end with a pulley O, and on the top of the gas-holder B there is an arm P, provided with a loop 19, adapted to slide up and down on the post 0, and to which loop p is secured one end of a cord or chain Q,

which passes up over the pulley O and down through the ring on on the lever M, whereit is provided with a weighted button or plate q, adapted, as the gas-holder B settles down, to engage the ring m and raise the lever M, so as to open the valve J, and as the gas-holder continues to rise again close it, the valve being thus opened and closed, as the gas-holder rises and lowers, as desired.

In the loop 19 there is pivoted a laterallyprojecting arm R, from the outer end of which depends a rod R, forked at its lower end, so as to engage the oscillating pipe L. This rod R is adapted to be swung from side to side, as illustrated by dotted line in Fig. 1, so as to engage either end of the oscillating pipe L.

In operation, the carbid-holders O and D being charged with carbid and the oscillating pipe L turned down, so as to deliver water from the tank K, say, to the carbid-holder O, as the gas generated therein passes into the gas-holder B it gradually rises, andafter it has risen, say, one-half of its upward traverse it operates upon the valve J to cut off the Water-supply, when it again lowers, the water is again turned on, and this operation continues until the carbid in the holder 0 is exhausted. After this as the gas is used from the holder 13 it gradually settles down until the arm R engages the oscillating pipe L and connects it with the carbid-holder D. The water-supply now at first flows directly from the tank A through the diagonal hole j in the valve-plug, meanwhile also flowing into and filling the tank K as the gas-holder begins to raise, the diagonal hole j is out OE, and thereafter the water is supplied from the small tank K, as before. Meanwhile the cock 6' can be closed and the carbid-holder O recharged and the rod R swung over into the position shown in the dotted line in Fig. 1 ready to 1 switch the pipe L when the carbid-holder D is exhausted. It will thus be seen that this wise interfering with the operation of the machine. Therefore,

Having thus described my invention and the operation thereof, what I claim as new, and desire to secure byLetters Patent of the United States, is

1. The combination in an acetylene-gas generator, of a gas-holder, two carbid-holders connected therewith, valve mechanism connected with the gas-holder and operated by the raising and lowering thereof, and an oscillating pipe adapted to connect said valve with one of said carbid-holders at a time, and mechanism on the gas-holder for switching said pipe from one carbid-holder to the other, substantially as and for the purpose set forth.

2. The combination in an acetylene-gas generator, of a gas-holder, two carbid-holders connected therewith, shut-01f cocks and a for conveying water to one of the carbidholders at a time, and a swinging arm on the gas-holder adapted to move said oscillating pipe from one carbid-holder to the other, substantially as and for the purpose set forth.

3. The combination in the water-supply .mechanism of an acetylene-gas generator, of an auxiliary tank connecting through a three- ?way valve both with the gas-holder tank and with a pipe for supplying water to carbidholders, lever-and-weight, and stop mechaniism for controlling said valve, and mechanism connecting said valve-lever with the gasholder, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

LABAZURE O. MCLANE.
