LANTERN.

SPECIFICATION forming part of Letters Patent No. 241,953, dated May 24, 1881.

Application filed October 8, 1880: (N 0 model.)

To all whom it may concern Be it known that I, EDWARD P. FOLLETT, of Rochester, in the county of Monroe and State of New York,-have invented a new Improvement in Lanterns; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, which said drawings constitute part of this specification, and represent, in-

Figure l, a side view; Fig. 2, a vertical central section of the lower part; Figs. 3 to 11, detached views.

' This invention relates to an improvementin that class of lanterns in which the air, or a portion of it,-to support combustion is brought down from the top through tubes opening into an air-chamber below or around the burner, parts of which are applicable to other classes of lanterns; and the invention consists in the construction hereinafter described,.and particularly recited in the claims.

A represents the lamp-fount, of any known or desirable form; B, the air-chamber; G G, the tubes which lead from above andopen into the air-chamber B in the usual manner; D, the burner, setin the top of the air-ch amber beneath the deflector E. Around the deflector is the rest or support F for the globe G, all in substantially the usual relation to each other.

The air-chamber B is made from a single disk of sheet metal, as seen in Fig. 10, its outer edge, b,turned down to form the outer wall and set upon the top of the lamp-fount. At the center an opening is made for the burner, and the metal around this opening is turned downward to form a flange, d, and which corresponds to a central opening in the top of the lampfount, so that the flange 12 forms the outer wall, flange d the inner wall, and flat portion 0 the top of the chamber B, the top of the lamp-fount f forming the bottom of said chamber B, as seen in Fig. 2. The space at the center within formed bythe flange d is made to correspond to the shape of the base hof theburner, and so that theburner will fit closely therein. By this construction the outer and inner walls and the top of the air-chamber are made in a single piece of sheet metal,and at the same time forms the combustion-chamber around the burner.

seat for the burner. Preferably the lower edge of the flange d is turned inward, as at t, (see Fig. 10,) and so that the lower edge of the base of the burner will rest thereon as a bearing.

The burner D is constructed with a hook, it,

(see Fig. 6,) on each side, so as to set through corresponding slots, m, in the top of the airchamber, and then given a partial rotation to bring the ends of the hooks beneath the top 6, to secure the burner in its seat.

The deflector E is-hinged to the top of the air-chamber, as at 1", (see Fig. 2,) and forms a The top of the air-chamber is perforated within the combustion-chamber, forming an air-distributor for the in-flowing air.

The wick-tube,as seen detached in Fig. 7, and in section Fig. 11, is divided vertically at the sides, each part formed with a slight flange at the edge, and each turned over at the top to form a flange, s, in a horizontal plane around the top of the burner. This flange is perforated to admit su-tflcient air to the base of the burner to support combustion and turn or direct a greater portion of the air to the flame above the base. The result of this is an increase or enlargement of the flame at the base, and copsequently an enlargement above, it being understood that the perforations must be back from the edge of the wick-tube. flange then serves, in fact, as a spreader for the flame.

In the usual construction of removable globelanterns the cap or top is movable vertically,

This

so as to set down upon the neck of the globe, 8

and locked in that position secures the globe" in place. If the globe be a little too long, the pressure will be very great, if a little too short, then the globe will be loose and rattle; but

even if it fits properly the expansion and conengages the frame when the cap is down; but

when the two arms are disconnected from the frame then the cap, ring, or neck-holder may be raised, as seen in broken lines, Fig. 1.

I provide a yielding support for the globe, in combination with the adjustable cap or ring, as follows:

H is a ring of elastic metal outside the dc flector and hinged to the air-chamber, as at a. To the upper edge of this ring the globeholder F is attached. This globe-holder consists of a ring of sheet-metal, (see Figs. 2 and 9,) attached by its inner edge to the upper edge of the ring H, and curved downward and outward, as seen in Fig. 2, its outer edge turned upward to form a seat, 2r, for the globe. Numerous slits, or, are made from the outer edge of the holder radially inward, so that the outer edge of the holder forms a series of independent springs, upon which the globe will rest. Thesesprings, being independentot'each other, yield to the unavoidable irregularities of the lower edge of the globe, and consequently insure a close fit of the globe entirely around its base. They also form an elastic holder, which readily yields to any expansion of the globe, so that however firmly it may be held it is not liable to be broken, as is necessarily the case with rigid holders. The wick-adjuster shaft L extends outward through the side of thedefiector and through the ring H below the globeholder, as seen in Fig. 1,the deflector and ring Hha-ving a notch, so as to close down over the said shat'tL. Theburnerisfirstsetinplace,then the deflector and the globe-holder turned down. The notches therein passing out the adjustershaft prevent the burner from becoming detached by any accidental turning which might occur.

The guard is made detachable, and consists of two parts joined at each side. Each part forms two semicircles, N. These two semicircles are made from a single piece of wire bent to bring the two semicircles into planes parallel to each other-that is, one above the otherand so as to make a vertical connection, P, between them at each side or end of the semicircles, as seen in Fig. 3. The two semicircles, so bent and connected, form one-h alf the guard, the vertical connection of the one half meeting the vertical connection of the other half each side the globe. Then the vertical connections are joined by a piece of sheet metal, R, its edge turned around the vertical portion I, as seen in Fig. 4-, which firmly unites the two parts so as to form a circular guard for the lantern. The connections R are made to fit the outer surface of the tube 0, and correspondingly inclined so as to slide down over the tubes to the position required for the guard, and as seen in Fig. 1.

I do not broadly claim a wick-tube made in two parts, nor do I broadly claim a wick-tube with a spreader at the base of the flame; neither do I broadly claim a lantern having a removable guard composed ol' concentric rings of wire; but

What I do claim is- 1. In a lantern, the globe-holder consisting of a metal ring having its outer edge bent to form a seat for the globe, and radially slitted from the outer edge to form independentsprings upon which the globe will rest, combined with a vertically-movable cap or ring at the top arranged to set down upon the neck ot'the globe to hold it in place, or raised to remove the globe, all substantially as described.

2. A lantern-guard made in two parts, each part consisting ottwo concentrical semicircles, N N, with vertical connections I, made from a single piece of wire, and the said two parts joined at the said vertical connection, substantially as described.
