GAS-HOLDER.

SPECIFICATION forming part of LettersPatent No. 684,849, dated October 22, 1901. Application filed January 20,1899. Serial No. 702,831. (it. inodel.)

To all whom it may concern: I

Be it known that I, J OHN Sr. LEGER MCGINN, of the city of Winnipeg, in the Province of Manitoba, Dominion of Canada, have invented certain new and useful Improvements in Gas-Holders; and I do hereby declare that the following is a full, clear, and exact description of the same.

y invention relates particularly to acetylene-gas holders; and it has for its object to provide a holder that will be exceedingly simple to construct and free from danger and that Will not have an exposed water seal, while the exposed surface of the seal within the gas-holder is reduced to a minimum, and consequently the evaporation thereof will be correspondingly reduced.

The invention may be said, briefly, to consist of an expansile chamber, a casing inclosing said expansile chamber and containing a seal therefor, a communicating passage between said chamber and casing, said passage being normally closed, but adapted to connect said chamber and the interior of the casing at the time said chamber expands to amaximumdegree, a constantly-open blowofi passage from said casing to the open air, and a pair of gas-conducting pipes leading, respectively, to and from'said chamber.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts, and wherein- Figurel is a side elevation of my improved holder Fig. 2, a transverse vertical sectional View thereof, taken on line 2 2, Fig. 1.

My improved holder consists of an inclosing'casing in which a gas-receiving drum 6 is located,'this drum being of the usual dome formand fits over a second dome-like structure 7, the lower edges whereof are connected by an annular diaphragm 8 to the lower edge of the inclosing casing. This casing is constructed in two parts 5 and 5. The upper part 5 has an encircling bead 40 near the lower end thereof. In fitting the parts together the lower edges of the upper part are slipped into the upper end of the lower part 5 until said bead comes into contact with the edge of said upper end, and a strip 41 is soldered at its upper and lower edges, respectively, to said bead and the upper end of the part 5.

A vertical tubular section 9 is formedcentrally of the innermost dome and communicates by a horizontal pipe 10 with the lower end of the space between said inner dome and outer casing. The drum has a tube 12 extending from a central opening in the top thereof downwardly into the tubular passage formed by said tubular section 9, to which it approximately corresponds in length, and said tube 12 has a pair of holes 30 near the lower end thereof.

The gas-conducting pipe 14 from the gen= erator (not shown) is taken into the inclosing casing at a point below the diaphragm 8 and upwardly through the innermost dome-like structure and through the top thereof to communicate with the space between said structure and the drum. The water for sealing purposes is supplied to the space between the said structure and the outer casing through a pipe 15, formed on the exterior of the casing and leading from the lower end of said space upwardly to a point about on a level with the point at which it may be desired to keep the water seal. A holder as thus constructed will be found to contain many advantageous features, in fact, all that can be desired; but I prefer to augment same by providing means whereby the means for causing the carbid and water to combine can be actuated by the expansion and contraction of the gas-chamber-i. 6., the chamberintermediate the drum 6 and dome 7. To this end the outer casing 5 has a tube 13 extending from a central opening in the top thereof downwardly into the tube 12 to a point a short distance below the top of the tubular passage 9. A rod 20 is secured at its lower end to the lower end of the tube connected to the drum 6 and projectsupwardly through the tube 13 and has a transverse disk 21 secured upon its upper end. H

A lever 22, having one end weighted, as at 28, is fulcrumed upon a standard 23, secured on the top of the casing, and has its inner end formed with a flared fork having prongs 24: and 25, the prong 25L being pivot-ally connected to the lower end, as at 27, in such a way as to insure a one-way movement thereof relatively to the lower end. This construction of the fork insures that the disk will pass clear of prong 25 and engage the lower prong 2% as the gas-chamber in contraction approaches its minimum capacity, while the upper prong 25 is simultaneously caused to extend over said disk to be engaged thereby as the chamber expands and also that the -disk will clear said upper prong 25 after the lever has been moved the required distance;

When the gas is completely exhausted from the gas-chamber, the disk will assume the position shown in dotted lines in Fig. 2 and in doing so will release the prong 24: and allow the weighted end of the lever to fall, while upon the chamber again expanding the disk will rise and trip upon said prong 24c and cause same through its pivotal connection with its lever to move out of its way. The outer end of the lever is connected by a rod 30 or in any other Way to the means (not shown) for causing the carbid and water in the generator to combine.

What I claim is as follows:
