JOHN HENRY STONE, OF HAMILTON, ONTARIO, CANADA.

TUBULAR LANTERN.

- SPECIFICATION forming part of Letters Patent No. 324,183, dated August 11, 1885.

Application filed March 17, 1884.

To all whom it may concern.-

Be it known that I, JOHN HENRY STONE, of the city of Hamilton, in the county of Wentworth, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Tubular Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

This invention relates to improvements in lanterns, and has for its object to provide novel and efficient means whereby the upper part of the lantern with the globe can be elevated above the burner without removing the globe for lighting, trimming, and other purposes. This I accomplish in the manner and by the construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, illustrating my invention, in which- Figure 1, Sheet 1, represents a front elevation of my lantern. Fig. 2, Sheet 1, is a detached view of slide and grooved plate with section of tube. Fig. 3, Sheet 1, represents the sliding attachmentat the bottom of the tubes. Fig. 4, Sheet 2, is a front elevation of lantern, showing the globe, &c., raised above the burner. Fig. 5, Sheet 3, represents a front elevation of lantern with sliding attachment on the outside of the tubes. Fig. 6, Sheet 3, is a cross-section of tube on the line a a, Sheet 3. Fig. 7 is a front elevation of lantern with the sliding attachment on the outside of tubes, and upper part of lantern and globe raised above the burner for lighting, trimming, and filling.

A is the base or reservoir of the lantern; B, the horizontal section of the tubes jointed at the line mm; D, the slide-plate attached to the end of the vertical section 0 of the tubes, and made to slide in the grooved plate E, which is fastened to each end of the horizontal section B of the tubes. (Shown particularly in perspective at Fig. 2, Sheet 1.) F is a vertical slot cut in the grooved plates E, and F a slot cut through the braces G, respectively, which are made to strengthen the grooved plates E,

and I is a wire bent around the base of the burner and passed through the said slot in each groove, plate E, and brace G, and their outer ends fastened to the slides D, respectively; and it may be observed that this said (No model.)

wire I also supports the perforated disk H, which holds the globe. Thisdevice retains the globeinits place when it is elevated above the burner,'as shown at Fig. 4, Sheet 2, for lighting, trimming, and filling. The upper and lower parts of the lantern are held together by any ordinary locking device. That shown is an eye, I), affixed to the right elbow of the tube 0, and a hook, c, fastened to the base A, which is made to catch in said loop or eye I), when the upper and lower tube-sections, 0 B, are connected as in Fig. 1. The said hook c is thrown off the loop or eye I) when the upper section of the lantern, with I the globe, is raised up above the burner, as at Fig. 4, which is done simply by an upward pull on the handle with one hand, while the base A is held down with the other. A ring, L, surrounds the top of the globe K and keeps it in its place. It is connected to a plate, N, at the top of the air-chamber P, said plate being connected with a lifting-ring, M, for raising the ring L off the globe. A spiral spring surrounding the plate in the air-chamber pushes the ring down on the globe to hold it. It may be observed that the slidingarrange- Inent could be placed on the outside of the tubes. Joint the tubes above the elbows; solder a three-sided plate, 6, on the outside of said tubes 0, as shown at Figs. 5, 6, and 7, so as to leave space enough for a spring sliding plate, f, to pass through, each plate f being secured to the lower section, B, of the tubes, the wire I in this case being soldered or otherwise secured to the ends of the upper section, 0, of tubes, and a locking device made to hold the two sections of the tubes together. That shown is the same hook c hereinbefore described, being fastened to the lower section, B, of the tubes, and hooking or catching on the wire I, as shown at Fig. 5, Sheet 3. In raising the upper part of the lantern the said hook 0 is thrown off the wire I and raised, as in with an oil-cu p baseand globe-plate, of the seewire connected with a globe'plate and passed tional air-tubcs, the plates attached to one seethrough the slotted plates and braces and setion of said tubes, and the way-plates attached cured to the sliding plates, substantially as dcto the other sections for the reception of the scribed. I 5 first-named plates, substantially as described. Dated at Hamilton, Ontario, this 8th day of 2. In a tubular lantern, the combination of March, A. D. 1884. sectional air-tubes, grooved plates formed with T 7' V T 1 vertical slots and attached to one section of the JOHL HENIA S tubes, the grooved braces to said plates, the In presence of- IO plates attached to the other section of said \VM. BRUCE,

tubes to slide in the grooved plates, and the WILLIAM CAMPBELL.
