WATER SEAL FOR GAS-GENERATORS.

Specification of Letters Patent.

Patented Oct. 10, 1911.

To all whom 'it may concern:

Be it known that I, AUeUsrUs E. SCHLIEDER, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have inventedcertain new and useful Improvements in Water Seals for Gas-Generators, of which the followingis a specification.

This invention relates to improvements in an acetylene gas generator and more particularly to an improved water-seal box or casing in the form of a casting adapted to be fastened to the casing of the gas storagetank.

The primary object of my invention is to so construct a generator that the numerous openings through the sheetmetal wall of the gas-tank may be dispensed with, also the usual lock-nuts used in conjunction with pipes entered into or passed through the sheet-metal walls of the gas-tank.

Another object of my invention is to dispense with the pipes in the water-seal, which after a short period of time would have their screw-threads rust and would tend to break in two.

A further object of my invention is to so construct the gas-tank that the waterseal chamber as well as the tank-proper may be emptied through openings in the waterseal box or casing instead of applying internally-threaded metallic-bushings in openings formed in the side of the sheet-metal tank and closing the bores of the same with plugs.

It also has for its object the provision of means for assuring a graduated feed of gas into the gas-bell of the gas-tank, so that the pressure in said bell can never be increased in impulses or sudden jerks, thus assuring a steady light without flickering.

These and other objects to be hereinafter described, provide a more economical structure than has heretofore been possible to produce and save considerable expense and labor on account of the dispensation of pipes to form the water-seal, and it also avoids the necessity of cutting numerous small holes into the sheet-metal wall of the tank for the reception of internally-threaded metallic bushings into which the several pipes of a gas-tank are usually threaded.

To these ends the invention consists in the provision of a cast-metal water-seal box or casing introduced into the gas-tank through a single opening and having the various pipe-connections threaded thereinto without exposing the threads to the action of the water in the water-seal chamber.

It also consists in the construction, arrangement, and combination of parts to be hereinafter described and particularly pointed out in the subj oined claims.

In the drawings,-Figure l is a perspective view of my improved water seal box or casing and the adjacent portion of the gas tank, the pipes connected thereto being omitted. Fig. 2 is a vertical longitudinal section taken on line 2-2, Fig. 1. Fig. 3 is an enlarged horizontal section taken on line 33, Fig. 2. Fig. 4 is a vertical section taken on line 4l4, Fig. 2 looking in the direction of the arrow crossing said line. Fig. 5 is an enlarged vertical section taken on line 55, Fig. 2 looking in the direction of the arrow crossing said line. Fig. 6 is a vertical section taken on line 66, Fig. 2 looking in the direction of the arrow cross ing said line. Fig. 7 is a vertical section taken on line 77, Fig. 2 looking in the direction of the arrow crossing said line.

Referring now to the drawings in detail, like letters of reference refer to like parts in the several figures.

The reference letter A designates the gas generating-chamber wherein calcium carbid is deposited and which by contact with water causes generation of gas to be delivered into the gas-bell B through a waterseal usually in the lower end of the gas tank.

My improved water-seal comprises a box or casing C of cast metal which is set into an opening 0 in the wall of the gas-tank and it has its outer wall extended beyond its sides to provide flanges 0 that over-lap the sheet metal of the tank and are riveted or other-wise secured to the same in a water- 0 a rear wall 0 side walls 0 and a top 7 wall 0 having its rear portion inclined, as at c. The top wall is extended beyond one of the side walls of the box or casing proper and with a short vertical wall 0 forms a cap or dome D lying wholly in a plane above 1 a wall or partition E which separates the gas-chamber F of the tank from the waterseal chamber G at the bottom of the tank. The upper end of the water-seal box or casing proper also extends into the gas-chamber and said box or casing is provided with a horizontal flange H which extends also along the lower edge of the cap or domes D and is adapted to bear against the underside of the wall or partition E to which it is riveted or otherwise fastened, said wall or partition having an opening E through which the upper end of said box or casing projects. The lower end of said box or casing is open to permit the water in the waterseal chamber G to enter the same.

The water-seal box or casing is divided into two main chambers I, and I which are separated by a vertical wall J having its lower edge provided with teeth 7' and being inclined from the front wall of the box or casing to the rear wall thereof; said teeth being preferably V shape for a purpose to appear hereinafter.

Threaded into the front wall of the box or casing so that it will open into the upper end of the chamber I is a gas inleadingpipe K leading from the upper end of the gas-generating chamber A to the water-seal box or casing; and threaded into the inclined portion 0 of the top wall is an outlet-pipe L which delivers the gas to the gas bell (not shown) of the gastank after having passed through the water-seal box or casing. The gas delivered into the chamber I of the water-seal box or casing forces down the water therein until the gas is permitted to pass around the toothed lower edge of the wall J, and on account of said edge being inclined, the gas will first pass around the highest point of said edge, which is at the inner end of the first of the series of notches 7' formed by the teeth j, until the pressure increases and passes between other teeth in succession and finally clears said edge at every point. The inverted V-shaped notches 7' formed by the V-shaped teeth permits a constant feed of gas around the edgevof said wall or partition, irrespective of the pressure under which said gas is delivered into the water-seal box or casing, and consequently the gas is stored in the gas-bell of the gastank with an unbroken flow so that the pressure within said bell will be increased gradually; thus assuring steady lights and preventing flickering of the same.

The toothed wall J may well be termed a graduated gas-feed or regulator and as gas cannot be generated under a constant pressure, said graduated gas feed or regulator prevents the feeding of gas to the gas-bell in impulses or under quickvariations ,of pressure.

A gas delivery pipe M is threaded into the outer wall of the box or casing at m to deliver gas from the upper end of the chamber I and, as this chamber is in constant communication with the gas-bell, the gas therein is held at the same pressure as the gas in said bell when generation of gas ceases, but during the generation of gas, the pressure in said chamber momentarily exceeds the pressure of the gas in the gas-bell, until the excess pressure is sufficient to raise said gasbell. The gas stored within the gas-bell may be forced down through the pipe L and may be delivered through the pipe M for use.

A transverse-chamber N is provided about midway between the upper and lower ends of the chamber I and has a passage 71 extending therefrom to the upper end of the box or casing where it opens into the gas-chamber F; said transverse chamber and the passage n being formed by a wall a connecting the rear wall of the water-seal box or casing with the front wall thereof. A threaded opening 0 is provided in the front wall of the water-seal box or casing in line with said transverse chamber; and said opening is closed with a plug 0. The passage it also opens at the rear of the box or casing, as at W, so that the water in the gas-chamber can be completely drained by removing the plug 0 and allowing the water to pass through the passage 01-, into the transverse chamber N and out the threaded opening 0.

For thepurpose of draining the lower or water-chamber of the tank, a threaded opening P is provided in the front wall of the water-seal box or casing near the lower end thereof and it has a plug 7) threaded therein to close said opening in a water-tight manner.

A vent-pipe R is threaded into the front wall of the water-seal box or casing for communication with the cap or dome, and a safety or gas-escape pipe S is threaded into the upper wall of said cap or dome to permit the escape of the gas from the gas-bell when under excess pressure; said gas escaping through the pipe S from the gas-bell, entering the cap or dome D and passing out through the vent-pipe R into the open air. Owing to the cap or dome lying in a plane above the bottom of the gas-chamber F and being closed to said chamber, the water cannot enter it, neither can the gas escape through said cap or dome and pass around the lower edge of the water-seal box or casing proper, as this is prevented by the water in the water-seal chamber and on account of the pipe R being open at all times for the escape of the excess quantity of gas, the gas will pass out of said pipe and thereby avoid all possibility of the apparatus becoming damaged or exploding.

By providing a water-seal box or casing made of cast metal and having comparatively thick walls, the various pipes and outlets with which gas-tanks are usually provided, can be threaded into said box or casing; and by locating said box or casing at the side of the gas-tank, it is accessible for threading pipes into it from the outside as well as from the inside. It also possesses the advantage of dispensing with numerous openings in the thin sheet-metal walls of the tank and also with the cast nuts or thimbles which must be secured in the numerous openings in a water-tight manner for the reception of the threaded ends of the various pipes. My invention also dispenses with the pipes and pipe-fittings to form the water-seal and which invariably become rusted and weakened at the threads of the pipe and are considered the weakest part of the gastank, they sometimes rusting to such an extent as to break in two at the threads. Another desirable feature of my invention is the provision for draining both the water-seal chamber and the gas-chamber through openings in the cast water-seal box or casing. If for any reason the pressure of the gas becomes excessive, it can break the water-seal and escape around the lower edge of the box or casing, rise into the cap or dome D, and pass out into the open air through the pipe B.

By the use of my invention, all pipes are drained directly into the water-seal box or casing.

Various modifications of this invention may be resorted to without departing from the principle involved, and I therefore do not wish to limit myself to the exact construction herein shown, but desire that the subjoined claims be given the broadest interpretation permissible by the prior art.
