ACETYLENE-GAS GENERATOR.

Application filed December 5,1899. Serial No. veegzeo. (rib model.)

lyclare, in the cou nty of Antrim, Ireland, have invented certain Improvements in Apparatus for the Manufacture of Acetylene Gas, of

which the following is a specification.

This invention relates to improvements in means for the generation of acetylene gas from carbid of calcium, said means being auto matic in character and designed with the object of introducing the carbid of calcium into the generating-chamber in exact proportion to the consumption of gas from the holder or gas-container and without allowing escape of gas either during the operation or when the vessel or chamber containing the carbid requires recharging with such.

Our invention comprises the use of one or more vessels or chambers to contain the carbid of calcium and which are attached in a suitable position to. the chamber or vessel in which the gas is generated, communicating therewith by means of one or more passages in accordance with the number of carbid-containers employed to each generator, such carbid-container having fitted within it a gastight piston or plunger that may be suitably operated so as to discharge the requisite quantity of carbid into the generating-chamber, such piston covering or sealing the passage between the carbid-container and generator when the whole of the carbid has been discharged therefrom while such passage is beingclosed by a suitable valve and immediately prior to the recharging of the container with a fresh supply of carbid of calcium.

Our invention will be fully described with reference to the accompanying drawings, in

whichand sediment may occasionally be drained off, and at the top an open end in which is iriserted a gas-holder O. The latter is provided at the lower end with a perforated bottom B, pivoted to the holder 0, so that it can be canted till it assumes a vertical plane by means of the rod X and leverX'. The upper end of the gas-holder O is closed except for a passage E, which communicates with the chamber D,containing the carbid of calcium either in lumps or powder. The chamber D, which may be of any length and diameter, is suitably mounted and secured on the gas-holder O, and its interior may be put into communication with the passage E, leading to the gas-holder, or shut 0E therefrom by the valve or cock F. One end of the chamber D is provided with a removable sealing-lid N, while the other end is bored for the reception of apiston or plunger rod H, to the interior end of which is secured a piston-head G, which is made to have a gas-tight fit with the wall of the chamber. The rod H may also be surrounded with a stuffing-box H, either as a further precaution.

to prevent escape of gas or in substitution for forming a gas-tight joint with the piston-head G. The latter is sufficiently wide to entirely cover and seal the opening to the passage E when the piston reaches the end of its forward stroke and all carbid has been discharged. The outer end of the rod H carries two antifriction-rolls h, between which is passed a rod J, acting as a variable inclined plane, the lower end of which is pivoted to the generat- .ing chamber A or to another suitable part of the apparatus or its framing, while its upper end is coupled to a second rod K, the free end of which is passed through a bracket M,mounted on the upper framing M of the apparatus. The lower side of the rod K rests on a roll m in the bracket M, while its upper side is provided with ratchet-teeth to engage with a spring-controlled catch L, also carried by the bracket.

The gas-holder O is capable of a rising-andfalling movement, according as the gas is generated or consumed, and is guided in such movements by the antifriction-rolls G, which bear against the guides O. In order to regulate the pressure of gas in the gas-holder and to assist it in rising, one or more weights O are used, suspended from one end of a chain, the other end of which is passed over pulleys O. and secured either to the gas-holder or to the chamber D at P, as shown. T is a pipe through which the generated gas passes from the gas-holder O to the condenser V and through the regulator and purifier W to the burner.

Assuming that the apparatus described is empty, the operation of gas-generation is as follows: The generating-chamber A is supplied with water through the side at A", the cocks A and F- being closed. The gas-holder is at its lowest position, andthe chamber D is charged with carbid of calcium, its open end being afterward sealed by the cover N. The piston G is at the right-hand end of the chamber D. The valve F is new opened, allowing a quantity of carbid to fall into the generating-chamber. As gas is evolved the gas-holder C rises, and the rod H pulls inwardly the rod J, so that its upper end movesj vforward the rod K in the bracket M. As the gas is consumed by passing through pipe T' the gas-holder C descends; butthe rod K .is firmly held by the catch L, thus holding the rod J at a fixed angle. This being so, any further descent of the gas-holder causes thei rod J to push the piston-rod H and piston-f head G inwardly, thus discharging carbid from chamber D into the gas-generator 0,1 and so generating more gas. The fit of the; piston-head G in the cylinder is sufficientlyi tight to cause the piston to remain immovable during the rising of the'gasometer-belhi andthus drawing in on the rod J, causing it to assume a more vertical position and sliding the rod K still farther through the bracket, where it is again engaged by the pawl Land-i prevented from returning. If the-quantity} of gas evolvedis greater than that beingcon-i sumed, the holder rises again and the feed? of thecarbid stops; but immediately the cons-umption increases the gas-holder descendsj still farther and fresh carbid is'discharged This action continues until the whole of the; carbid is discharged, and it will'be seenth'atl in-all cases the quantity so discharged must beproportionate to the consumption. When? the charge of carbid is exhausted, the piston; Gis covering the passage from the chamber! D to the gas-holder 0, thus preventing escape of gas into the chamber D to the rear of thei .piston. The cock F is then closed, 'theendi N-removed, the catch L disengagedjTandtheQ piston-head G and rod K moved back, after? which the chamber D is recharged with car-f} bid and the cover N placed in position again. 5 Thereafter gas-generation proceeds againias described.

The piston-head G may beactuated in 'sev' eral difiere'nt ways. Thus in'Figa2 the chain 1 S is continued forward under-apulleyS to.

ftheend of the rod H, to which it is :attached,

while-inFig. 3 the piston is actuatedbymeansl of a weight Q on a chain Q working overpul-l leys B, one set of pulleys being-mounted on the cylinder D and the other set of pulleys carried by a bracket secured to the rod H, the outer end of which engages with the rod J, as in Figs. 1 and 2.
