ACETYLENE-GAS GENERATOR.

SPECIFICATION formingpart of Letters Patent No. 716,556, dated December 23, 1902.

Application filed February 5. 1900. Serial No. 3,978. (No model.)

To aZZ whom, it may concern.-

Be it known that I, SWAN M. KLARQUIsTpf the city of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specifica tion.

This invention relates to acetylene-gas generators; and the objects of the invention are to provide a safe and convenient gas-generator that is automatically controlled by the gasometer and to provide means for thoroughly washing and purifying the gas before it enters the gasometer.

A further object is to provide a gas-generator having a carbid-receptacle wherein the calcium carbid or other gas-producing material is exposed in small quantities only to the action of the water and saturated as fast as it is needed, the main body of the carbid being kept perfectly dry.

A further object is to provide means for locking the water-supply valve until released by the movement of the gasometer.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a vertical section of a gasgenerator and gasometer embodying my invention. Fig. 2 is a horizontal section on the line arm of Fig. 1. Fig. 3 is a vertical section on the line y y of Fig. 2. Fig. at is a detail showing the interior of the carbid-reoeptacle. Fig. 5 is a detail of one of the carbidcans. Figs. 6, '7, and 8 are details of the mechanism for operating the valve in the pipe leading from the generator.

In the drawings, 2 represents a tank adapted to contain a supply of water and provided with a horizontal wall or floor 3, forming a second bottom for the tank. Between the wall 3 and the bottom proper of the tank a space or chamber is provided that is divided by vertical partitions 4E and 5 into chambers or compartments 6 and 7, the latter receiving the gas from the generator and being called, therefore,the washing-chamber. The partition at extends from the bottom of the tank to the wall 3 and is provided with a series of openings 8, and the partition 5 is spaced from the partition 4; and preferably extends only to the surface of the water when the chambers are filled. A filling-spout 9 is provided on the side of the tank, through which the chamber 6 may be filled with water, which,

flowing through the holes 8, remains at the same level on both sides of the partitions. A hole 10 is preferably provided in the wall of the tank near the top, over which I arrange a lip 11 for convenience in filling the tank. The tank is provided with an open top, and within the same I arrange a gas-holder or bell 12, having a closed top and open bottom and provided with a central tube 13, in which a guide-rod 14, provided on the bottom 3, is slidable. WVithin the gas-holder I provide a gas-inlet pipe 15, leading from the chamber 7 to a point above the surface of the water in said holder and through which the gas passes from the washing-chamber to the gas-holder. Upon the opposite side of said tank I provide a gas-outlet pipe 16, leading from the space above the water in the holder through the chamber 6 and preferably provided in said chamber with a T 17, that is connected to the service-pipe 18 and is provided with a pipe 17, extending below the surface of the water in the chamber 6, forming a water seal for the gas-outlet pipe. I also provide a safety-pipe 18, telescoping with a pipe 18 on the holder, said pipe 18" being provided with a hole 18", normally below the water-line, through which the gas passes to the safety-pipe and the outer air should the pressure raise the holder beyou d the desired point. I prefer to provide a drip T 19 on the pipe 18 within the chamher 6.

Below the surface of the water within the chamber 7 is a strainer-cup 19, connected to a pipe 20, leading to the interior of the generator 21. The generator is provided with a tight-fitting cover 22, held in position by a clamp device 23. Within the generatorI arrange a removable carbid pail or bucket 24, divided by vertical partitions 25 and 26 into compartments, preferably fourin number and of equal size and wherein I arrange a series of triangular carbid-cans 27, placed one above the other, the lower can of each series being provided with lifting-straps 28, provided with rings 28', and all the cans having depending flanges 29 at the bottom to fit over and form a close joint With the top of the can immediately beneath. The carbid pail or bucket 24 is provided with a series of holes 30, leading from the space between the walls of the pail and the generator to thecompartments formed by the partitions 25 and 26. I prefer to provide one hole or opening for each compartment and arrange them in a circle one above the other in the walls of the pail near its top, so that as the water in the generator rises to the level of the first hole it will flow in upon the carbid in one compartment and will not enter the others until it reaches the level of the holes leading thereto. Each carbid-can is preferably provided with a series of holes 31, arranged, preferably, near the upper edge of the can, and also with holes 32 and 33, the former being near the top and the latter near the bottom of the can. The water entering the lowest hole of the series in the pail will flow down to the bottom of the pail and entering the hole 33 in the can will attack first the carbid at the bottom of the can. If the water continues to rise, it will enter the hole 32 and act upon the carbid at the top of the can and will continue on in this manner through the entire series of cans. If, the carbid having been exhausted in the first compartment, the water continues to flow -into the generator it will soon rise to the height of the hole in the pail leading to the second compartment, in which the carbid will be acted upon, beginning with the contents of the bottom can, in the manner already described, and so on through the entire series of compartments. With this construction only a small quantity of the carbid is exposed at any one time to the action of the water, and there is in consequence no waste of the carbid and no excessive accumulations of gas. The main body of the gas-producing material will be kept perfectly dry and exposed to the water only as it is needed in the generation of the gas.

On the inner wall of the generator and extending below the level of the water therein I provide a lip or flange 34, and leading from the space between said flange and the wall of the generator is a water-supply pipe 38, extending to the tank 36, supported on the wall of the tank 2 above the generator. The flange 34, extending below the level of the water in the generator, forms a Water seal for the supply-pipe. On the opposite side of the generator I provide a U-shaped overflow-pipe 37. In the pipe 38 is a valve 35, to the stem of which is attached a fork 39, having prongs 40 and 41. The prong 40 is preferably longer than the prong 41 and slides in a channel-bar 42, that is vertically slidable in guides 43 and is connected at its upper end by a strap 44 with an arm 45 on the gas-holder. The channel-bar 42 is provided with a slot 46, and a bar 47 extends across the slot and is proriatse vided with a beveled face to prevent the prong 41 from catching thereon during the descent of said bar 42. The channel-bar being connected to the gas-holder, the flow of water to the generator and the generation of gas therein is absolutely controlled by the movement of the holder. As the gas passes out of the holder it will slowly descend, and the fork projecting through the slot in the channel-bar, as shown in Fig. 6, will be carried down to the position indicated in Fig. 8 and the valve opened, allowing the water to flow into the generator. As the gas flows from the generator into the holder it will slowly ascend, raising the channel-bar 42, and gradually close the valve and shut off the supply of water. When the holder is in its elevated position, the fork will be in the position shown in Fig. 7 and the prong 40, fitting in the groove in the channel-bar, will prevent the valve from being opened again until the gas passes out of the holder and it begins to descend. When the gasholder is in its down position, the prongs of the fork will be within the slot in the channel-bar, as shown in Fig. 8, and it will not be possible, without breaking the fork, to close the valve and shut off the supply of Water to the generator. The generation of gas is thus automatically and positively controlled by the rise and fall of the gas-holder, and as the valve will be locked, whether open, closed, or in an intermediate position, all accidents due to tampering with the water-supply valve or to the carelessness of an attendant will be prevented. As the gas is generated and rises to the top of the generator it will pass down through the pipe 20 into the washing-chamber and after being thoroughly cleansed will pass up through the pipe 15 into the top of the holder. The pressure of the gas in the washing-chamber will be balanced by the weight of the water in the chamber 6, so that a uniform water-level will be maintained in each chamber. When the holder has risen to a certain predetermined point, the hole in the pipe 18" will be above the level of the water, permitting the gas to enter and escape through the safetypipe. The partition 4 being imperforate above the water-line will prevent the gas from passing over the partition 5 from the washing-chamber to the chamber 6, and the partition 5 being imperforate below the water-line will prevent the gas under pressure from passing through the perforations beneath the water-line in the partition 4, and an effectual water seal is thus formed between the chambers.
