IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 173,577, dated February 15, 1876 application filed January 3, 1876.

To all whom it may concern: V

Be it known that I, JOSEPH M. BATGHELOR, of Foxcroft, in the county of Piscataquis and State of Maine, haveinvented certain new and useful Improvements in Lanterns; and I do hereby declare that the following is afnll, clear, and exact description thereof, that will enable others skilled in the artatp which it appertains to makeand use the same, reference being bad to the accompanying drawings, forming a part of this specification, in which- Figure 1. shows a lantern with my invention attached. Fig.2 shows a lantern as. commonly made.

Same letters show like parts. 7 The object of my invention is to provide a means by which the tubular lantern in common use may be lighted without removing. the globe. My invention consists of a simple spiral spring, resting upon and surrounding the cone of the lamp-burner, and exerting an upward pressure upon the perforated disk which supports the globe. This upward pressure is overcome by the downward pressure of the spring at the top of the lantern; but

when the lamp is tobe lighted, and this latter spring is compressed by raising the upper disk, 'niy attachment causes the lower perforated diskand the globe to rise, leaving a passage to the wick'through which the match may be inserted.

'In the drawing,'l ig. 2 shows the ordinary tubular lantern, with the upper disk raised, preparatory to removing the globe for the purpose of lighting the lamp. At a is shown the globe resting upon the perforated disk I), and kept thereon by the downward pressure of the spring 0, (where the said spring is in its usual position,) acting through the disk or cover d at the top of the globe. At 0 is the cone of thelamp-burner, upon the base of which rests'the annular perforated disk b, also kept in place by the action of the spring 0. This is the usual construction of lanterns of this class, and they are lighted by raising the upper disk or cover d, as shown in Fig. 2, and removing the globe.

' My invention contemplates no change in this construction, consisting merely in the ad dition of a spiral spring, 5, (see Fig. 1,) resting upon the shoulders of the cone 0, and bearing upward against the perforated disk b. When the lamp is to'be lighted, the upper disk or cover is raised, as usual, relieving the globe and disk I) from the pressure of the spring 0. This spring 1' causes the perforated disk I) and globe a .to rise also, giving access to the lamp-- Wick under the disk I), as shown, and holding the globe firmly in its raised position.

What I claim as my invention, and desire to secure by Letters Patent, is'

In combination with a tubular lantern,-constructed substantially as shown and described, the spring 2', arranged and operating substantiallyas set forth and shown.

In testimony that I claim the foregoing, I have hereunto set inyhand this 24th day of December, 1875.
