UNITED STATES PATENT OFFICE.

JOHN H. CALKINS, OF COLUMBUS, OHIO.

ACETYLENE-GAS APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 658,829, dated October 2, 1900. Application filed e 9,1900- Serial No. 19,692. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. OALKINS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of. Ohio, have invented certain new and useful Improvements in Apparatus for Generating Acetylene Gas; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the kind of apps;- ratus shown in the patent of the United States granted to Charles D. Howells, dated the 24th day of October, 1899, No. 635,727; and the present invention is an improvement upon the sort of apparatus shown in said patent.

My invention resides in a carbid box or drawer provided with a perforated tube to receive and sustain a cloth containing the carbid, said tube being movable with the carbid-drawer, so that the cloth containing the carbid can be placed to surround the tube, thereby insuring a more rapid and thorough mixing of the Water with the carbid.

The invention resides in the.,parts and combination of parts set forth in the following description and claims.

In the accompanying drawings, illustrating an embodiment of the invention, Figure 1 is a side elevation of the apparatus, the end of the drier being also projected in plan. Fig. 2 is a top plan View of the apparatus, the drier omitted. Fig. 3 is a view of the removable head of the, carbid or generating chamber. Fig. 4 is an elevation on the left-hand end of Fig. 1. Fig. 5 is a top plan view of the carbid drawer or box. Fig. 6 is a side view. Fig. 7 is an end view of the handled endof the carbid-box. Fig. 8. is a sectional view looking to the left on the plane indicated by the line 00 m, Fig. 6.

Like characters ofreference in the several views designate corresponding parts.

O designates the generating-chamber. Secured to or arranged upon the upper side toward one end of this chamber is a water reservoir or tank B, from the bottom of which extends a pipe f, havinga regulating-valve b and a nozzle that protrudes into the chamber 0, as indicated by dotted lines, Fig. 1. Se-

cured to or arranged above the upper side of the generating-chamber is another water-tank D, in which is the coil of the delivery-pipe h to convey the gas from the generator. The delivery-pipe h, after it leaves the the tank D, communicates with a vessel E, called a drier, to contain lime and charcoal or other material adapted to absorb moisture from the gas, and the gas from the drier is conveyed to the points or point of consumption by other appropriate pipes.

A drawer F to contain the carbid is constructed to fit well within the generatingchamber 0. It is shown to be of partially-cylindrical form, somewhat resembling a trough, having circular heads. Between the heads of the drawer I secure a tube 70, perforated on all sides. The tube 10 is secured in a position to incline from the inner head down toward the outer or handled end of the drawer, and the inner or higher end is secured to an opening in the head of the drawer, so that when the drawer is properly slid into the generating-chamber the nozzle end of the pipe fwill discharge into the tube 10.

The carbid is placed in a cloth that has been pressed down on both sides of and around the tube is, so that it practically surrounds said tube, as indicated in Fig. 8. Therefore when water from the reservoir B is discharged into tube is it rapidly and thoroughly saturates a large quantity of the carbid, and hence promptly generates an abundance of gas.

One end of the generating-chamber is furnished with a movable cover or head G. Any appropriate means can be employed to fasten this cover in place; but those shown comprise cam-bails 'n, pivotedin eyes 'i on the chamber C. The outer parts of the bails are pressed upon by a yoke m, that is forced and held against the bails by a nut Z on a screw p. The inner side of the movable head G has a suitable spring 0, (shown in dotted lines, Fig. 1,) that presses the drawerhome and holds it there.

Excess of pressure of gasin the chamber 0 finds its escape in a popvalve c, and the gas thus escaping passesthrough a pipe ato a hooded flue A. The water in the tanks B and D can be drained when desired through cocks e and e, respectively.

d is a water-glass to render visible the height of the water in the tank B.

When the carbid is exhausted, the cloth containing the ashes is lifted out of the drawer and the ashes removed, after which the cloth can be refilled.

What I claim, and desire to secure by Letters Patent, is

1. In an acetylene-gas-generating apparatus having a generating-chamber O, and a tank B to supply water thereto, a drawer F for said chamber and a perforated tube in said drawerand movable therewith into which tube water from the tank B drips or flows, said tube being adapted to receive and support a cloth containing the carbid, substantially as described.

2. In an acetylene-gas-generating apparatus having a gas-generating chamber 0, and a reservoirB to supply water to said chamber, a drawer F for said chamber and an inclined perforated tube It in said drawer into which water drips or flows from the reservoir B, substantially as described.

In testimony whereof I aflix my signature 25 in presence of two witnesses.
