ACETYLEN E-GAS GEN ERATO R.

SPECIFICATION forming part of Letters Patent No. 594,826, dated November 30, 1897. Application filed July 19, 1897. Serial No. 645,040. (No model.)

sists in the production of a case or cabinet constructed substantially as herein shown and hereinafter described adapted to hold both the liquid and the solid (separated) and to automatically precipitate measured quantities of the said solid into said liquid and to store and automatically control the pressure of the gas generated by their union, as

will hereinafter appear.

My invention relates especially to the production of acetylene gas produced from the union of water and 'calcium'carbid.

In the accompanying drawings, which form a part of this specification, Figure 1 is a per spective view of my generator complete. Fig. 2 is a top View of the case or cabinet detached from the gas-holder. Fig. 3 is an end view of the same. Fig. 4 is a section of Fig. 2, taken on the line 4 4; and Fig. 5 is a detail.

Similar letters refer to similar parts throughout the several views.

The cabinet A may be made of any suitable material (galvanized iron being adapted to its construction) and of any desired form. Its cover a may be hinged thereto, or it may be removable therefrom. It should be provided with suitable clamps to hold it in close contact with an interveningpacking. Said clamps and packing I do not deem it necessary to show, as such devices are common and form no part of my invention. The shelves b are hinged to its interior side or sides (preferably the latter) intermediate its height. 7 They are supported in a horizontal position by means of latches 0, but are adapted to swing downward to a vertical position when the said latches are deflected. Each of these shelves bis adapted to holdv either a fixed or a removable case or magazine d, holding the calcium carbid, and when in a horizontal position, as shown by b, Fig. 4, keeping it apart from the water with which the cabinet A is charged, but when in a vertical position, as shown by dotted lines in same figure, precipitating it therein. It will be understood that when the magazines cl are affixed to or integral parts of the shelves 1) they precipitate their contents into the Water below, but when removable therefrom they (with their contents) are precipitated into the water, from which they are recovered when recharging the cabinet A. The latches c, which support the shelves 1;, may be held in position by means of the spring f, as shown by e, Fig. 4, being spring-latches, or they may be so fashioned as to be held in place by their own weight, being gravity-latches.

The shaft 9 is journaled in the ends of the cabinet A, extending outward from one of them; It is provided with a number of cams h, one for each pair of shelves, as shown. These cams operate to deflect the latches c,

and are so set upon the shaft g that their projecting points will operate in turn, to the end that but one of the latches 0 will be deflected and but one of the shelves 1) will be dropped at anyone time.

A ratchet-wheel 11, having as many teeth as there are-magazines (Z, is affixed to the end of the shaft 9 which extends out through the end of the cabinet A. It operates to intermittingly rotate the shaft g.

The rock-shafts j (like the cam-shaft g) are journaled into the ends of the cabinetA and with the same should be provided with a suitable stuffing-box. They operate to lift the shelves (9 back into a horizontal position.

The pendent rod k is connected with the rising-and-falling case of a telescope gasholder. It operates in its downward movement to intermittingly rotate the ratchetwheel 1' by contacting with and pressing down on the teeth.

The click Z operates to control the intermittent action of the ratchet-wheel i and prevent its rotating backward or in the wrong direction.

The pipe m connects my generator with a telescope gas-holder not unlike those in common use. It is provided with the valve n' to shut off communicationbetween the generator and the gas-holder.

I operate my device as follows: I first ad mit or pour water into my cabinet A, leaving it about one third full. I then charge the magazines with calcium carbid, close down and clamp the cover. I then open the valve 01 of the connecting-pipe m to provide for storing the gas and turn the ratchet-wheel 71 one tooth, thereby rotating the shaft 9, dc,- fiecting one of the latches c, dropping one of the shelves 1;, and emptying the contents of or precipitating one of the magazines 01 into the water below. Through this operation acetylene gas will at once be evolved, penetrate the water, accumulate in the cabinet A, above the same, flow through the pipe m into the telescope gas-holder and by its expansive force lift the movable case thereof. Then as the gas is exhausted at the burners the movable case of the telescope gas-holder will fall by gravity, carrying with it the pendent rod 7a, the lower end of which will contact with one of the teeth of the ratchet-wheel i, which it will rotate one tooth, when the abovedescribed operation will be repeated until the last magazine has been emptied or precipitated.

Thus it will be seen that my generator (after being started) is automatic in its operation.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1., The combination with a telescope gasholder, of a case or cabinet having horizontally-supported shelves hinged to its interior side or sides, magazines supported by, and latches supporting, the said shelves, a shaft having cams mounted thereon, and aratchetwheel affixed thereto, a pendent rod operated by the rising-an d-fallin g case of the said telescope gas-holder, adapted when on its downward course to contact with a tooth of, and to rotate said ratchet-wheel, and a pipe connecting the said case or cabinet, and the said telescope gas-holder, substantially as shown, and for the purposes specified.

2. The combination with the telescope gasholder of a case or cabinet having horizontally-supported shelves, magazines supported by, and latches supporting, the said shelves, a shaft having cams mounted thereon, and a ratchet-wheel affixed thereto, a pendent rod attached to, and operated by the risingandfalling case of the said telescope gas-holder, and a pipe connecting the said case or cabinet and the said telescope gas-holder, substantially as shown and for the purposes specified.
