ELIAS O. GLAZIER, OF ROCHESTER, NEV YORK, ASSIGNOR TO THE STEAM GAUGE AND LANTERN COMPANY, OF SAME PLACE.

TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 372,533, dated November 1, 1887.

Application tiled July 7, 1856. Serial No. 207.2518.

T all whom it may concern:

Be it known that I, ELIAS O. GLAzrER, of the city of Rochester, in the county of Monroe and State of New York, have invented new and useful Improvementsin Tubular Lanterns, of which the following is a specification.

This invention relates t0 that class of tubular lanterns in which the globe is mounted in a lifting-frame which can be raised from the burner when the same is required to be exposed for trimming the wick, lighting or eX- tinguishing the lantern, or for removing the burner.

The object of my invention is to improve the devices whereby the globe-frame is raised and lowered; and my invention consists to that end ofthe improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of a tubular lantern provided with my improvements, the globe being lowered. Fig. 2 is a similar view showing the globe raised. Fig. 3 is a top plan view of the lantern. Fig. 4: is a side elevation of the upper portion of one of the side tubes. Fig. 5 is a vertical section in line x x, Fig. l.

Like letters of reference refer to like parts in the several figures.

A represents the base of the lantern, containing the oil-pot A', airchamber B, and burner C.

D D represent the side tubes, D' the central tube connected with the upper ends of the side tubes, D, and E they bell or funnel mounted upon the central tube, D', so as to slide on the same.

G represents the globe, H the plate upon which the globe rests, and I I the side wires connecting the plate H with the bell E opposite the inner sides of the tubes D.

.I represents the annular springcatclnwhich is secured to the under side ot' the bell and which holds the upper end of the globe.

K represents an upright arm or bar which is secured to the bell E in front of the central tube, D.

L represents a lever pivoted to the central tube, D', above the arm K, andprovided with 5o a slotted segment, Z, which engages with a (No model.)

stud, m, secured to the arm Kin such manner that by turning the lever L in one or the other direction the bell and the globe-frame attached thereto 'are raised or lowered. The arm K being rigidly secured to the bell, the turning of the segmentlon the pivot of the lever L causes avertical niovemcntofthe bell on the tube D'. Vhen the globe-frame is in its lowest position, the lever L is placed under a projecting stop, n, formed ou one of the side 6o tubes, D, whereby the globeframc is locked down and the burner is securely held in position, whether the globe is in place or not, as represented in Fig. 1. Vhcn the globe-frame is raised, the lever Lis placed under a stop, a', 65 secured tothe opposite side tube, whereby the globe-frame is locked in an elevated position, as represented in Fig. 2. The side wires,

I, pass through guide-loops z', secured to the side tubes; but as the lifting-frame is locked 7o in its elevated position by the vlever L the wires I can pass loosely through the loops without the friction which is frequently employed for locking the globe-frame in an elevated position, thereby facilitating the movements' of the globe-frame. The lever L cnables the globe-frame to be moved with ease, and as the lever projects laterally from the central portion ofthe lantern it remains cool, andis therefore more conveniently handled 8o than a thumb-piece which is located directly over the bell. The base A, side tubes, D D, and central tube, D', constitute the rigid lantern-frame, in which the globe-frame is made vertically movable.

Vhile my invention is more particularly designed for use in tubular lanterns in which the tubes supply air to the burner, it may be employed in lanterns having tubular frames which supply no air to the burner.

I claim as my invention- 1. The combination, with the rigid lanternframe, of a globe-frame capable of vertical movement in the rigid lantern-frame, and a lifting-lever pivoted to the rigid lantern-frame 95 above the globeframe, and having its free arm projecting laterally from said pivot and its other arm connected with the upper end of the movable globe-frame, substantially as set forth.

IOO

2. The combination, with the rigidlanternframe, of a globe-frame Capable of vertical movement in the rigid lanteru'- frame, aliftinglever pivoted to the rigid lantern-frame above the globe-frame and having one of its arms'- segment which engages with tbe globe frame, su bstantially as set forth.

4. The combination, with the rigid frame provided with a central tube, D', of a globeframe provided with a bell, E, capable of sliding on vthe tube D', and provided with an arm, K, having a stud, m, and a liftinglever, L, pivoted to the rigid frame, and provided with a slotted segment, Z, which engages with the stud m, substantially as set forth.

Witness my hand this 2d day of July, 1886.
