TUBULAR LANTERN.

UNITED STATES PATENT OFFICE.
THEODORE A. GLENDE AND WILLIAM B. FRANKENSTEIN, OF ROCHESTER, NEW YORK, ASSIGNORS TO PRITCI-IARD STAMPING COMPANY, OF ROCHESTER, NEW YORK, A
CORPORATION OF NEW YORK.
TUBULAR LANTERN.
Specification of Letters Patent.
Patented July 4, 1916.
To all whom it may concern Be it known that we, THEODORE A. GLENDE and VILLIAM-B. FRANKENSTEIN, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Tubular Lanterns, of which the following is a specification.
This invention relates particularly to a tubular lantern in which wire members such, for example, as the slide-guides controlling the globe-cage, are secured to the air-tubes, and the object of the invention is to produce a simple and strong construction for securing such wire members to the tubes, and particularly to accomplish this without the use of solder.
To the foregoing end we employ the construction hereinafter described and illustrated in the accompanying drawings.
In the drawings :Figure 1 is a partial front-elevation of a lantern embodying the present invention; Fig. 2 is a perspective view showing, in detail, a portion of one of the air-tubes with a wire slide-guide fixed thereto in the manner of the present invention; and Fig. 3 is a horizontal section through the parts shown in Fig. 2.
The invention is shown as applied to, or embodied in, a. tubular lantern of a wellknown form, this lantern having the usual air-tubes 5 and globe 6. The globe is mounted in a cage or frame comprising side-wires 7, and these side-wires engage and cooperate with slide-guides 8, of which the general form is shown particularly in Fig. 2 and is not novel. The invention is illustrated particularly as embodied in the connection between each slide-guide 8 and the corresponding air-tube. For this purpose the tube is provided, on either side of its central vertical wall 9, with a pair of perforations 10, 11, arranged in vertical relation, and between these two perforations the sheet-metal is pressed outwardly to form a channel or ofiset 12 extending beyond the body of the tube. The slide-guide is provided with a straight portion 13, near each end, which lies in the offset 12, as shown particularly in Fig. 3. Tolnrevent longitudinal movement of the wire in the offset it is provided with a short bend 14: just above each upper perforation 10, this bend servingto prevent the wire from sliding downwardly. To prevent the wire from sliding upwardly its lower extremities are bent back and upwardly, so as to closely embrace the offset 12. Since the pressure of the slide-wires 7 against the slide-guides tends to force the latter toward the tubes 5, each guide is provided, just above the bend 14, with a reverse bend which constitutes an abutment adapted to rest against the outer surface of the air-tube and thus resist the pressure.
Prior to assembling the parts the slideguide is made complete as shown, except that the extremities 15 are in a straight line with the parts 13. The ends of the wire are then passed downwardly into and through the perforations 10 and 11, and it is then necessary only to bend up the extremities 15 in order to complete the structure. Owing to the complete interlocking of the parts it is unnecessary to use any solder in fixing them together, and the construction of the lantern is thus cheapened without the sacrifice of strength.
The outward ofi'setting of the metal between the perforations in the air-tube is an important feature of the present invention, since it permits the slide-guide to be inserted and locked in place by operations performed wholly from the exterior of the air-tube, and without the necessity of providing perforations of a diameter any greater than that of the wire which is introduced. 7e are aware that, in a lantern of the railroad type, it has been previously proposed to fix the guard-wires in place by passing them through perforations in the body of the lantern, but in such proposed constructions the guard-wires, when introduced, have been bent or provided with lugs or lateral projections, so that in introducing them it has been necessary either to use unduly large perforations, or to sever the metal of the body on a line between the perforations, or to introduce the wires by an angular movement, such as is not practicable in the case of the slide-guide of the present invention.
\Vhile the construction above described is particularly useful in connection with slide-guides of the kind referred to, it will be apparent that it may be employed in connection with other wire members which it may be necessary to secure to the airtubes.
We claim 1. In a tubular lantern, the combination of an air-tube having a pair of perforations, and the metal between the perforations unbroken but outwardly offset from the body of the tube; and a wire slide-guide having a straight part lying in said perforations and said offset, an outward bend engaging the end of the offset, an inward bend engaging the body of the air-tube beyond the offset, and a portion, beyond said inward bend, adapted to perform the function of a slide-guide.
2. In a tubular lantern, the combination of an air-tube having, on each side of the middle of its inner surface, a pair of vertically spaced perforations, and the metal beoutwardly offset from the body of the tube; 5
and a wire slide-guide having two parallel end-portions which extend through said perforations and lie in said offsets, each end being bent both above and below the corresponding offset so as to secure the wire in place without soldering.
