Letters Patent No. 89,536, dated April 27, 1869.

IMPROVEMENT IN LAMPS. l

The Schedule referred to in these Letters Patent and making part o1 tha im To all whom it may concern Be it known that I, JOSEPH S. WOOD, oi- Plainfield,

New Jersey, have invented a new and useful Improve. ment in Atmospheric-Gas Lamps, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had -to the accompanyin g drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the con struction of lamps for burning hydrocarbon or other light oils.

These lamps are to be attached to ordinary gaspipes in dwellings; also to railroad-cars or Steamers.

An air-forcing apparatus is attached to the pipes,

in some convenient position, and atmospheric air is forced through the bsorbents in the said lamps. 1t thus lbecomes impregnated -with hydrocarbon-vapor, and passes out at the burner.

The air, on its passa-ge to the burner, previous to entering the absorbente, is heated by the dame from the burner.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a general elevation of the whole arrangement.

Figure 2 is a section through the lamp.

Figure 3 is a perspective view of the burner.

Figure 4 is a section through the regulating-receiver.

Fig. 1 shows the blowing-apparatus, A, commonly used in carburetting air.

On its top Vis the pipe a', entering the water-tank B, fig. 4, containing an inverted receiver, C.

An interior pipe, c, with holes, c2, slides over thel tube a'.

An arm, d, connects with the stop-'cock (Z2, upon the gas-pipe E, and so, by the rising and falling of the receiver C, the vpressure in the gasfpipes is regulated.

The gaslamps G are screwed upon the gas-pipes, in the place of the usual burner.

The cock F is the same as that used for ordinary coal-gas, and is used for turning the gas on or off.

In iig. 2, G is the body of the lamp, in globe form, containing the absorbente S.

YH is au inlet for gasoline, and closed by a screwluv.

D Bhe stem K screws into the gas-pipe E.

The tube L divides into two branches, L and M. The branch M is closed at the top, except a small opening, on., the opening of which is regulated by the thumb-screw 11.

v A tube, N, tits loose upon the tube M, leaving space for lthe carburetted air to pass between.

The top of this tube terminates in a burner, O.

The tube L passes upward, as shown, into the' hollow dame-spreader?, and, down the opposite side,

L', into the body of the lamp, where it is perforated with holes, R, for the escape of atmospheric air.

The llame-spreader P is shaped as shown in g. 3. Itis hollow, for the passage of atmospheric air, and has an annular opening around the burner, for a current of fresh air to pass upward to the flame.

The operation of my apparatus is in this way:

and then with hydrocarbon. All that which is not absorbed is poured out again, and the inlet H closed. This feature of the lam'p makes it non-explosive. The lamp is now screwed upon the gas-pipe E. The blower A is set in motion, and pumps air along the pipes E, the force ot' the current being regulated by the receiver C acting upon the cock di.

The cock F is turned, and air passes into the lamp G.

the tube L, into the dame-spreader P, which is heated by the jet of llame from the burner, and imparts its heat to the air passing through it.

The air descends in the tube L', and passes out through the openings R, and diffuses itself amongst the absorbent S, where it is impregnated with hydro- M and N, to the burner `O.

If the gas is too rich, the valve mis opened, and air from the adnlterating-pipe M is allowed to mix with the gas.

This lamp can also be used upon a table of a parlor, air being conveyed from the pipe E by an elastic In dia-rubber tube.

This lamp will burn without the flame-spreader P material, it will only burn three hours; and, if the lair is heated wit-h my hollow flame spreader and tubes, the lamp will burn eight hours, and burn up all the materia-l.

I do not claim forcing air, through gas-pipes, into self-generatingvapor lamps, as that lhas been previously done.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. lhe lamp-body G, in combination with the tubes L M and flame-spreader P, for the purpose shownand' described. p

2. The combination of the globe G, containing an absorbent, S, with pipes L, M, and N, and burner O, arranged and operating substantially as described.

3. rlbe adulterating-pipe Ml and valve m n, for the purpose shown and described.

4. Heating the impelled current of air, at or near the point of combustion, as it passes on its way, through the absorbent S, to the burner.

The lamp G is lled with an absorbent material, S,

This air fills the pipe M, but the current passes up carbon-vapor, and then passes up, between the tubes and-tube, but with this difference, that, with a pint of
