SPECIFICATION forming part of Letters Patent No. 632,117, dated August 29, 1899.

Application med July is, 189s. sain No. 686,315. in@ model.)

To @ZZ whom, t may concern:

Be it known that I, READ HOLLIDAY, a citt Zen of England, residing at Edgerton, Huddersfield, in the county of York, England, have invented new and useful Improvements in Lamps or Apparatus for Use in Burning Acetylene Gas, (for which I have obtained Letters Patent in Great Britain January 26, 1898, No. 2,078; in Germany June 4, 1898; in France June 7, 1898, and in Belgium June 8, 1898,) of which the following is a specification.

These improvements relate to lamps or apparatus for use in generating and burning acetylene gas produced in the lamps by the action of Water on calcium carbid or a similar body, and consist in bringing the water into contact with the carbid by the use of a capillary Siphon-that is to say, Water is conducted by means of a wick or capillary action to a higher level than the carbid, and by the continuation of the same or another wick or capillary conveyer attached to it the water is drawn downward into contact with the carbid. The descending wick can be opened out and distributed over or among the carbid so as to secure the best and most even production of the gas, the supply of water being stopped or regulated by a valve at one end of a tube, which preferably is that which serves as wick-holder for the ascending water.

Figure 1 is a substantially central vertical section through the lamp. Fig. 2 is a plan of the middle portion of the lamp with the cover removed.

A is the carbid-chamber.

B is the reservoir for water, formed by the outer water-tight wall B and the inner wall B2, leaving the carbid-chamber A referred to within the inner wall and completely isolated from the water in the space between those walls, except by means of the vertical passage afforded by the tube B2 between the two. This tube is lled by a capillary siphon, consisting of a Wick C, which has contact with the water, and passes up to and down into contact with the carbid in the chamber A. Theitube B3 is formed at the top end with a seatingB4fora valve D, mounted on a screwed stem D', which engages a correspondinglythreaded screw-opening in top of the cover E and is furnished with a milled head D2.

When this valve D is screwed downvby turnprojectiomwhich projection receives between its arms the screw-stem b', hinged at b2 to the outer wall of the lamp. This screw-stem b' is locked to the fork e by the screwed button h3, while for opening the cover in order to gain access to the internal parts of the lamp the button is loosened and the screw-stem carry` ing it is swung clear thereof. The cover E is formed With an annular recess, in which is held an annular ring of india-rubber or other suitable packing material, which ring when the @over is pressed into closed position forms a tight packing between those parts.

The L-shaped tube G serves to convey the gas generated in chamber A to the burner H, said burner being socketed in the junctionpiece G', connecting the pipe G thereto.

G2 is a screw-stopper to open or close the outlet G3 in the j unction-piece G' to let out any liquid.

B5 is a screw tubular passage communicating between the water-chamber B and the outer air, and into this tube fits the nipple B6, the line opening in which serves as an outlet to relieve any pressure in such chamber.

I is a supporting device for the lamp-body to the bracket of the machine; but any other usual or suitable device for the purpose may be employed to effect its support.

J is the burner-chamber, which is here shown provided with a hinged lid or cover J Between the burner-chamber in rear of the burner and the adjoining wall of the Water chamber B is interposed an insulating layer of asbestos j, through which and the respective thicknesses of metal B and J the rivets J' 'j paSS- J2 is an outlet'for the products of combustion, and J 3 is an asbestos shield provided to shield the same.

J 4 is the lens in the cover J By these means it will be seen that-the feed IOO of Water is attained by the controlled use of the capillary action of the cellular tissue of a fibrous material or Wick whereby the Water is raised in uniform and easilyregulated quantities from the Water-reservoir and deposited on and among the carbid or gas-producing material of a similar nature instead of by utilizing the flow of liquid under pressure With its attendant difficulties of regulation and Wastefulness.

Having noW particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is l. In a lamp for burning acetylene gas, the combination with a relatively-fixed carbidchamber, of a Water-chamber surrounding the same, a vertical feed-passage through the carbid-chamber and communicating at the lower end with the Water-chamber, a connection having capillary attraction extending through said passage and down into the carbid-chamber, an adjustable pressure-check mounted centrally over said passage and arranged to bear upon said connection at the point Where it is bent over the end of the' passage and press the same down against the upper end of the passage through the carbidchamber, as set forth.

2. In a lamp `for burning acetylene gas, the combination with a stationary earbid-chamber and a water chamber surrounding the' same and extending therebeneath, of a tube extending centrally through the carbid-cham ber and communicating at the lower end with the Water-chamber, a Valve seating on the upper end of said tube, a connection between the Water and carbid chambers extending up through the said tube and having capillary attraction and bent over the said seatin g, and a pressure-check independent of the chambers and adjustable vertically in line With said central tube to press upon the said connection at the point where it bends over the said seating as and for the purpose specified.

READ HOLLIDAY.
