CHARLES L. BET'IS, OF CHICAGQILLINOIS, ASSIGNOR OF ONE-HALF TO THE CHICAGO MANUFACTURING COMPANY, OF SAME PLACE.

TORCH-LAMP.

SPECIFICATION forming part of Letters Patent No. 316,440, dated April 28, 1885. Application filed April 30, 1884. (Xo modell) To a/ZZ whom it may concern:

Be it known that I, CHARLES L. Bnfrrs, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement inTorch-Lamps, of which the following is a specification. Y

In the present invention the lamp reservoir or bowl is made of glass, and is provided n ear its top or above its center of gravity with a bead or groove, on or in which tits a metal band or ring to which the supporting-frame is pivoted, either directly or indirectly, through a secondary swivel-ring or gimbals, when it is desired that the lamp shall be permitted to incline in both directions to the pole or staff of the torch.

Another feature of the invention consists in providing this bead or groove with notches or depressions for the ends of the pivots upon which the lamp swivels or turns, and also for the ends of the wireiguards, which are made to pass through or partially embrace the band or ring which lies in or over the bead or groove. It will be of convenience to construct the glass lamp with a neck having a cup-shaped flange or extension to serve as a drip-cup to catch any oil which may flow down from the wick. The neck itself may be also made long enough to afford a firm bearing and tight joint for a removable wick-tube, so that no cement or packing will be necessary. A cork, rubber, or other elastic sleeve may, however, with better results surround the wickstube. The wick-tube should be made long enough to extend to near the bottom of the glass reservoir, so as to envelop or inclose the whole length of the wick, by which means the wick can be readily inserted through the neck without danger of dripping the oil therefrom. The tube should be provided with perforations to admit the oil to the wick.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure 1 is a perspective view of a device embodying my invention. Fig. 2 is atop or plan view of the same. Fig. 3 is a cross-section on line 3 3 of Fig. 2. Fig. 4 is a side elevation of the glass reservoir with the frame'and band removed, and Fig. 5 is a side elevation showing a slight modification. Fig. G shows a modification wherein the notches to receive the ends of the guards are formed in the band, instead of the glass.

In said drawings, A represents the reservoir or oil-receptacle of the lamp, which is made of glass or similar material. B is a band or ring, which is rigidly secured to the glass lamp-reservoir A by means of the bead or 6o projection a, raised on the body of the glass reservoir near its top, or at least above its center of gravity, over which bead said band fits. The band or ring, when made of sheet metal, is provided with inturned flanges b b at its top and bottom edges to iit over the bead, and thus secure the band in place. If the band or ring B is made of wire, as shown in Fig. 5, it tits in the groove a. The band B is pivoted to a secondary ring, C, by the pins or rivets b b', and the ring C is in turn pivoted to the yoke or supporting-arms D, so that the lamp may incline in either direction to the torchst-aff or pole E, the pivots b b standing at right angles to the yoke or frame 7 5 D. The arms D are made of stiff wire, and are soldered at their lower ends to the polesocket F. The socket is made of sheet'metal, and should be provided with longitudinal grooves f, to receive the wiresD, so as to give 8o strength and rigidity to the frame.`

The glass reservoir A is provided with notches or depressions at in the bead or groove to receive the ends or heads of the pivots b', and similar notches, a, for the ends ofthe guardwires G. These notches or depressions, in connection with the pivots b, or the guards G, fitting in said notches, also serve to keep theband or ring in place and prevent its slipping or rotating on the reser 9o voir A. The guard-wires G may be four or more in number, and the diametrically-opposite guards may preferably be made continuous in one piece of wire. The guards G are all soldered together at thepoint Q,where they cross each other. The ends ofthe guards G have a short hook or bend, g', at their ends, which are inserted between the ring or band B and the glass reservointhe same resting in the sockets or notches a3 provided for them.

The ring B, if made of sheet. metal., as shown in Figs. l, 2, 3, and 4, should have holes b2,

H represents the wick-tube or burner. It is made of sheet metal, and is provided with perforations h. It ts within the glass neck a* of the lamp A, which neck is made long enough to afford apractically-tight joint; but a cork, rubber, or other sleeve, a5, may be inserted between the tube and neck. The neck a4 is provided with a cup-shaped Iiange, a6, at its top, which will serve to catch any oil that may exude from the wick. The wick-tube I-I has a bead, 7L', which fits down on top of the neck a4, and serves to make the joint tight.

In the modifications shown in Fig. 5,where be composed. of two separate pieces of wire, the endsof which are twisted at diametricallyopposite points, so that the twisted portions is pivotally connected with the frame D or the intermediate ring, C. The latter, however, in Fig. 5 is omitted. In Fig. 5 it will also be observed that the notches or depressions a? for I desire it be understood that in the specification and claims the bead a and groove a,as a means of securing the ring B to the glass reservoir A, are considered as equivalents of each other, and my invention includes either a raised or a depressed corrugation for securing the band to the glass reservoir.

W'here a sheet-metal ring having inturned flanges b is used,a notch or depression should be made in the glass reservoir where the ends of the ring unite, so that the same may be soldered together without the solder touching the glass.

By making the oil-reservoir A of glass in this manner a much'cheaper as well tas better torch-lamp is produced than where the reservoir is made of tin or sheet metal, and there is no danger of a glass reservoir leaking.

Instead of forming the notches a3 for the guards G in the glass as an equivalent construction, these notches may be made in the ring B.

I claiml. In a torch-lamp, the combination of a glass oil-reservoir, A, provided with a corrugation, with a ring, B, secured to said reservoir by said corrugation, and frame D, pivoted to said ring, substantially as specified.

2. The combination,with glass reservoir A, provided'with a bead or groove near its top having notches or depressions therein, of a ring, B, secured to said reservoir, and guards G, tting in said notches and secured to said reservoir by said ring B, substantially asspech fied.

3. The combination of glass reservoir A, pro` vided with acorrugation,with ring B, secured to said reservoir by said corrugation, an intermediate ring,C, pivoted to said. ring B,and 6 5 frame D, pivoted to said ring C, and provided' with socket F, substantially as specified.

4. The combination, withglass reservoir A, having a corrugation provided with notches or depressions therein, of a ring, B, ring G, having pivots b b tting in said notches, and frame D, pivoted to said ring C, substantially as speciiied.
