IMPROVEMENT IN LAN TEENS.

A; G. SMITH, OF JERSEY CITY, NEW JERSEY.

Letters Patent No. 59,865, dated November 20, 1866.

SPECIFICA'I'IQN Of certain Improvements in Lanterns, invented by A. G. SMITH, of Jersey-City, in the county of Hudson, and State of New Jersey.

The object of my invention is to produce a lantern which can be easily taken apart to be cleaned, while there is but little danger of the glass being broken by ordinary use, which shall, when in use, be little affected,

by the wind, and the various fastenings of which shall be simple, cheap, and eflicient.

It consists in an improved means of attaching the glass or globe to the upper part or frame of the lantern,-

so that when the said upper partis removed 'for the purpose of cleaning or trimming the lamp, the said globe shall remain fast to the said upper part or frame, thus being secure from breakage; in furnishing the said glass or globe at one or both ends with metal bands or rims, which further protect it from breaking; and in fastening the said globe to the said upper part or frame by means of a projection on the said'globe, working in a groove in said upper part or frame in such a manner that it may readily be removed for the purpose of cleaning when desired. Also in a new and improved mode of fastening the base or lower part of the lantern to the frame or upper part. Also in forming the lower edge of the globe with a square shoulder, and extending the top plate of the lamp or oil pot beyond the sides, so as to form a flange which shall deflect the air outward as it comes up between the lamp or oil pot and the lower rim or shell, and be deflected inward again by the square lower edge of the globe, to feed the flame in a superior manner.

In the accompanying drawings-- Figure 1 is a side elevation of a lantern embodying my improvements.

Figure 2 is a horizontal section through the line x :v, fig. 1.

Figure 3 is a vertical central section of the cap or dome of the lantern.

Figure 4 is a vertical central section of the glass or globe, with its metal bandsor rims.

Figure -5 is the base or lower part of the lantern, which contains the oil pot.

A is the cap or dome of the lantern, B the frame or guards, C the base or lowerpart, D the glass or globe and E the lamp or oil pot.

The glass D is fastened into the frame or guards B by means of a teat or projection, a, on the upper rim b, which enters a groove, 0, in the cap A at the point (i, fig. 3, where a slot or opening is made for it, and the glass is there turned around so as to fasten it in. In a cheaper lantern the rims!) and e may be dispensed with in which case the projection a may be made on the glass; or the projection may be made on the rim e, or the lower end of the glass, ahd a corresponding groove be made in the band'f. The rims and e are fastened to the glass D, by means of plaster of Paris, in the ordinary manner, and serve to give additional strength to the glass, and prevent its breaking under ordinarily careful usage. The upper and lower rims b and e fit snugly into the lantern frame, thus firmly holding the glass in place, and on the lower rim e a shoulder h is formed, which rests on the lower rim f of the lantern, and thus gives additional firmness to the glass G. The rims may be dispensed with, and the lantern be thus rendered cheaper, though more liable to break. By thus fastening the glass to or inside of the frame B, in a cheap and simple manner, it is protected from breaking when the frame B is removed to light or clean the lamp, and at the same time may be easily and quickly removed to permit its being cleaned when desired.

The base or lower part 0 of the lantern, which contains the oil pot, is fastened to the frame B on one side by a pin, g, and on the other by the burner shaft 1', each of which works in an angular slot or L in the rim f, acting in a similar manner to a bayonet fastening. A spring, j, shuts over the pin 9 when the two parts of the lantern are fastened together, thus preventing them from becoming unfastened. The'burner shaft 2' also works in a slot or L in the band f, which enables it to be removed with the burner K to fill the lamp, &c. The said shaft should extend through to theoutside of the lantern, 'so that the wick may be regulated from the outside. It will be seen that when the two. parts of the lantern are fastened together the joint is so tight, there being no openings left, that the air cannot enter sufficiently to affect injuriously the flame of the lamp.

The upper part or top of the lamp pot E is extended over the sides, thus forming a flange, Z, which deflects the air outward as it rises up through the holes in the base and band of the lantern to feed the flame, thereby preventing the flame being flared or disturbed by the wind. The air, after passing the flange l, strikes the base of the glass or globe, which presents a square shoulder, S, for the purpose of deflecting the current horizontally toward the bottom of the burner, and by this time the inequalities of its pressure, occasioned by-sudden gusts, being exhausted, it is fed to the flame in an even, steady current, which efl'eotually prevents the flame from being extinguished by anysudden downward movement of the lantern, or by a sudden or violent gust of wind. m is the upper and o the lower guard flange, f is the lower band, which is soldered or otherwise permanently fastened to the lower guardfiange. The lower guard flange and the lower band are made large enough to admit of the globe 1) being passed down through them, and this is done when removing it for the purpose of cleaning it. By thus soldering the lower band and lower guard flange together a much stifi'er and stronger frame is produced, which improves the lantern and makes it more durable.

Claims.

1. Fastening the glass or globe D into'the frame or guards B, substantially as and by the means described, so that when the said guards Band cap A are removed, thesaid globe shall remain fixed within the said guards B, while at the same time it'may be readily removed to be oleaned, substantially as and for the purpose set forth.

2. The combination of the metal rims I2 and e with the removable globe D, substantially as and for the purpose set forth.

3. The burner shaft 2' and pin 9, in combination with the band f, for the purpose set forth.

4. The deflector Z and square shoulder S, in combination, substantially as and for the purpose set forth.

5. The frame or guardB, provided with the groove 0 and the band f, in combination with the globe D, provided with the projection a, so that the, globe and the frame maybe securely fastened together, and the globe readily removed by passing it down through the band f. r
