IMPROVEMENT IN THE DO BERSINER HYDROGEN LlGHTER.

Specification forming part of Letters Patent No. 36,97E, dated November 18, l8"? T0 on whom it nmy concern.-

Be it known that we. JOHN TAYLOR and Rus- SELL W. BROWN, of Westerly, in the county of Washington and State of Rhode Island, have invented certain new and useful Improvements in Hydrogen Lighters for Domestic and other Purposes; and we do hereby declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of our invention; and Figs. 2 and 3 are magnified sections of the valve, Fig.2 showing the valve closed, and Fig. 3 the same open.

Our invention relates to the construction of the valve,whe'rebya very simple, eflicient, and cheap valve is secured, which is not liable to become leaky by use.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation by the aid of the drawings and letters of reference thereon, the sameletters referring toli'ke parts in all the figures.

A is ajar of glass or earthenware having a lid, B, secured thereto. From the under side of this lid is suspended a bell-shaped glass,G, extending nearly to the bottom of A, as represented, and within the bell G is suspended a piece of zinc, D. A mixture of sulphuricacid and water is poured into thejar A, and rising in the bell attacks the zinc, thus generating hydrogen gas, which collects in the bell and drives out the diluted acid until the zinc is no longer exposed to its action, when the formation of gas ceases. These parts and their action are similar to those heretofore known.

In the lid 13, and extending into the hell 0, is a nozzle, E, of the form represented. A chamber, a, is bored in the rear end, as repre sented, and a passage, 6, leads therefrom to the interior of the bell. Another passage, e, leads from this chamber to the front of the n0zzle,as represented, and the openings to these two passages are near the centerof the chamber 6. In the base of this chamber and surrounding the opening of the two passages e and e is an .annular lip or flange, e. A plunger, F, is fitted to play in the chamber 6 and to receive on its end a piece of india-rubber, G. -A spring, H, forces the plungertoward thebase of the chamher and causes the rubber G to tightly embrace the lip or flange e, and to enter the cavity within it, thus closing the openings of both the holes or passages eand e", and preventing the escape of gas through the same. A lever, I, is provided for lifting the plunger F and opening the holes e and e topern'iit the flow of gas from the-hell. A stop-screw, i, is provided to so gage the action of the lever I that lieve'd as to allow the holes 6 and e to be opened and gas to pass around from one to the other, the rubber Gcannot be sumciently lifted to relieve its pressure upon the lip 6*, so as to permitthe escape ofgas into the chamber 6. v The spring H is provided with a yoke, h, and screw h, whereby it maybe tightened to produce the required pressure to causethe rubber to tightly close both holes e and c. The gas escaping from ev impinges upon a piece of platinasponge, K, in the ordinary manner, and is thereby ignited, and maybe used to ignite a splinter of wood or other object placed therein.

In preparing the valve G we coat it with me-- tallic bronze-powder, to prevent it fromst-icking to the surface of the valve-seat, in the following manner: We first burn the surface of .the rubber so as to, cause it to firmly adhere to the socket in F, and then place ittherein. The portion which remains exposed is covered with bronze-powder, which adheres to the surface and forms a metallic coating, which, while it effectually prevents any adhering of the rub beer to the valve-seat, in no way interferes with the elasticity of the rubber. This coating is represented in the drawings by a thin yellow line.

As hydrogen-igniting apparatus has been heretofore constructed, the cock bywhich the gas was allowed to flow to the platina sponge was very liable to wear and become leaky, when the gas was constantly escaping and the useof the apparatus thereby rendered expensive and annoying.

By our improved construction the following advantages aresecured: The valve may always be kept tight with no perceptible wear. The rubber fitting always on thelip e prevents any escape of gas, except through'the passage e, and the strength of the spring H is easily adrubber G to tightly close one or both the hole: e or e. It will be seen that by this arrange l ment of theholes and valves 2. double securit while the pressure of thespring H is so far re justed by means of the screw h to cause the against leakage is obtained, for if either of these holes be stopped the passage is efi'eotually closed, even if the other beleft open. The valve G is very certain to close one, even if the pressure of the spring be not quite sufficient to close both.

. Our valve is self-closing and cannot be left open for the escape of gas like the ordinary cook. This is an essential advantage in doin'estie use, where inexperienced persons are liable to use the apparatus. p

By the coatingof therubbcr valve G with I bronze-powderall liability to derangement from' adhesion of the valve to its seat is avoided. The nozzle E and the other exterior parts may be made in various forms or designs to please the taste of the maker or customer without in terfering with the proper action of ourinvention, and the whole may be inclosed in a case to avoid the danger of breakage, if desired.

Having now fully described ourinve ntion,

what we claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of the two openings e and e and the surrounding lip e, or its equivalent, with the elastic valve G, as and for the purpose herein set forth.

2. The employment of the adj ustable spring H, in combination with the above, for the purpose described.
