MINERS LAMP.

QPECIPICATION forming part of Letters Patent No. 320,287, dated June 16, 1885.

Application filed April '7, 1885. (No model.)

To aZZ whom it 11mg concern:

Be it known that 1, HENRY J. Rrcrmnns, a citizen of the United States, residing at ,VilkesBarr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in miners lamps, and is designed to produce a lamp to be attached to the miners hat and burn that product of petroleum known as kerosene or coal-oil, without heating the forehead, and thus obviating the deleterious effects common to miners lamps.

The improvement consists, essentially, in providing a miners lamp with an air-duct surrounding the wick tube.

In describing the device, reference is had to the annexed drawings, in which Figure 1 represents a side elevation of the lamp, and Fig. 2 a vertical section thereof.

The lamp-body is made with an annular oilchamber,A, surrounding an internal air-chain ber, 13, which extends from the bottom to the top of the lamp-body.

Within the chamber B is contained a tube, 0, closed at the bottom and connected to the oil-chamber by short pipes or passages D.

Near the top of the chamber is provided a hole or holes, E.

Both the inner partition and the outer partition of the chamber A is continued upward, as shown at F, and receives a collar, G, on a tube, H, on the interior of which is a continuation of the wick-tube (J. A space is left between the tube H and the wick-tube, so that a current of air may pass from the bottom of the lamp to the burning portion of the wick when it is lighted.

The tube II may be secured to the body by means of screw-threads or grooves on each.

Oil is poured in the inlet I, and fills the chamber A nearly full, the hole E acting as a vent for the contained air. Through the tubes or pipesD the oil is supplied to the wick, which when the lamp is in use fills the tube 0.

A hook, K, serves to secure the lamp to the miners hat.

Heretofore the use of kerosene or coal-oil has been impossible, since the heat produced would so heat the forehead of the miner as to produce sores or baldness or turn the hair white at the front. The material usually used is a mixture of paraffine and a black substance, which prevents a too ready combustion. This substance is expensive and produces a thick, disagreeable smoke, besides easily clogging the lamp, the cleaning of which consumes valuable time to the miner.

The air duct in the lamp shown in the drawings prevents the heat reaching thehead of the miner and allows the use of kerosene or coaloil, which is inexpensive. The light produced is far superior to that produced from parafline, besides burning fora longer time, volume for volume.

I claim 1. A miners lamp having an oil-chamber, a wick-tube interior thereto, an air-chamber surrounding said tube, and a removable extension of both wick-tube and air-chamber, substantially as and for the purpose specified.

2. A miners lamp having an oil'chalnber, a wick-tube interior thereto and connected therewith, an air-chambcr surrounding the wick-tube, an 'inlet to the oil-chamber, and a vent therein, and a'continuation 0f the wicktube surrounded by an air-chamber, and removably secured to the lamp-body, substantially as and for the purpose specified.

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