GAS-PU'RIFIER.

SPECIFICATION forming part of Letters Patent No. 433,126, dated July 29, 1890.

Application filed March 3, 1B90| Serial No. 342,410. (No model.)

To all whom it may concern;

Be it known that I, JOHN HEARNE, of New York, in the county and State of New York, have invented a certain new and useful Improvenient in Gas-Purifiers, ot which the following is a speoication.

My improvement relates to so-called puriiie1boxes,inwhich are placed chemicals, over or through which illuminating-gas is passed in order to purify it.

I will describe a purifier-box embodying my improvement in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a vertical central section through two compartments of a box and the outlet-pipe common thereto. Fig. 2 is a top plan view of the same, the cover of the box being removed and the tray-holder being removed from one of the compartments.

A designates the body portion of the box, shown as of oblong form. It may be of any desired depth and has an open top.

B designates the cover for the box. The edges b of this cover, when the cover is in position upon the body, rest in a water lute or seal, formed in a trough or gutter b extending about the box near the top of the latter. The trough b has a closed bottom, formed by a ange b2, extending horizontally from and about the body A. One of its side walls is formed by the body A and the other by side pieces b3, which extend upwardly from the iiange b2 and somewhat above thc top of the body A.

The construction thus far described is not new.

C designates a trough or gutter which divides the upper part of the body A into two approximately square portions or compartments a a. The ends of this trough open into the trough b. lVater in the troughs b C will therefore be in communication and at the same level in both. Gas enters at Athe ports c in the bottoms of the portions a a', and, in the example of my improvement shown, finds exit through a pipe c', extending upwardly from the bottom of the gas-holder intermediate be tween the portions a a to a point above the water-level in the trough C. The outlet-pipe c', as it extends upwardly, gradually changes from a circular to an elongated form in crosssection, thereby economizing space between the portions a a and affording ample space for receiving the gas which passes up through the trays.

D D designate tray-holders, in which trays or grids D2, which may be of ordinary construction, are supported upon internal ribs or flanges d, extending horizontally about the interior of the holders. Chemical material adapted to purity the gas is placed upon the trays or grids. The tray-holders D D are of approximately the same shape as the portions a a and extend with a loose fit into them, and, when in position, nearly to the bottom of the box A. They have open tops and bottoms. Near their tops the said tray-holders are provided with horizontally extending flanges d upon all sides. From the outer edges of the iianges (Zv, flanges d2 extend downwardly upon all sides. Then the holders are in position the sides of the portions a a' ex tend into the space formed between the anges cl2 and the sidesof the holders, and the flanges d2 of the holders extend downwardly into the water lutes or seals formed in the troughs or gutters D C. Between the iianges (Z2 and the side pieces b'1 is sufiicient space to receive the sides of the cover B when the latter is placed in position. Gas entering through the ports c will pass upwardly about and over the chemical material placed upon the trays in the holders D D', and will, after being thus purified, pass outwardly through the pipe c.

XV hen the chemical material upon the trays or grids D2 becomes exhausted and needs revivifying or renewing, or when from any other cause it is desired to remove the chemical material from the portions a a', I lift out the tray-holders D D, and with them the trays D2 and the chemical material. This is conveniently effected by means of any suitable tackle-engaging rings g with which the trayholders are provided. This may be eected very quickly and avoids all shoveling of the chemical material from the trays or compartmcnts,as is now the common practice. The tray-holders having been lifted out, other trayholders, which, in the intervals of charging, have been rciilled with fresh material, may be as quickly lifted into position. The operation IOO of the purifier may in this Way be made practically continuous, being interrupted only for a sufficient time to lift out one set of trayholders and trays and insert a fresh set. The tray-holders which have been lifted out may be conveyed away in any suitable manner an d the material dumped from the trays Where desired. The trays may then be refilled ready for a fresh charge.

Although I have shown and described two tray-holders, I may of course use any desired number.

It Will be seen that by my improvement very much time and labor are saved, the great danger of asphyxiation which laborers expe-' take place around the tray-holders it could easily be detected from the outside.

That I claim as my invention isl. In a gas-purifier, the combination, With the body portion of a box surrounded near its top With a Water seal, of a cover adapted to extend into said Water seal, and a remov able tray-holder supported in said box beneath the cover and provided With a flange also extending into said water seal, substantially as set forth.

2. The conlbinatioinwvith abox and purifying compartment within the box, of a Water lute located between two purifying-compartments, and a gas-outlet pipe extending from the bottom of the `gas-holder up within the Water lute and having its upper end transversely elongated, substantially as set forth.

JOHN HEARNE.
