PATENT JOHN S. GALL, OF ROCHESTER, NEV YORK, ASSIGNOR TO THE STEAIWIVGAUGE AND LANTERN COMPANY, OF SAME PLACE, AND THE E. DIETZ OOM- PANY, OF NEV YORK, N. Y.

TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 481,276, dated August 23, 1892.

Application led October 8, 1888.

To all whom t may concern.-

Be it known that I, JOHN S. GALL, of Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Tubular Lanterns, of which the following is a specification.

This invention relates to that class of tubular lanterns in which the globe is mounted in a vertically movable frame, which can be 1o raised from the burner when access is required to the latter for trimming the Wick, lighting or extinguishing the lantern, or for other purposes, and which are provided with a liftinglever pivoted to the lantern above the glober 5 frame, whereby the globe-frame can be raised and lowered-as, for instance, in the lantern of the patent to Glazier, No. 372,533, dated November 1, 1887.

The object of my invention is to simplify zo the construction of the mechanism by which the globe-frame is raised and lowered and held in position at eitherextreme of its movement.

My invention consists of the improvements which Will be hereinafter fully described, and

pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of a lantern provided with my improvement, showing the globe-frame resting on the burner. Fig. 2 is a similar view showing the globe-frame elevated. Fig. 3 is a perspective View of the upper portion of the lantern. Fig. t is a top plan of the lantern.

Like letters of reference refer to like parts 3 5 in the several figures.

A represents the base of the lantern, coutaining the oil-pot A, air-chamber B, and burner C. I) Drepreseut the side tubes; (Z cl, the lower horizontal branches of these tubes;

4o d d2, the upper horizontal branches thereof, and d3 the central depending tube, connected with the upper branches d d2 of the side tubes. E represents the bell or saucer shaped plate, mounted loosely on the central tube d3,

so as to slide vertically on the same. G represents the globe, Il the plate on which the globe rests, and I I the side wires connecting the plate H with the bell E. J represents the annular spring-catch, which is secured to the 5o under side of the bell and which holds the sel-iai No. 287,541. (No man upper end of the globe. All of these parts may be 0f any suitable or well-known construction.

The base, the side tubes and their branches, and the depending central tube constitute the rigid lantern-frame, and the bell, with its spring-catch, the plate on which the globe rests, andthe side wires constitue the vertically-movable globe-frame.

K represents the lifting-lever, which is piv- 6o oted to the rigid lantern-frame near one of the uppercorners thereof andwhich extendsacross the front side of the lantern-frame above the bell and terminates with its free end near the opposite side of the lantern-frame. As shown in the drawings, the lifting-lever K is pivoted at 7c to the upper side of the upper branch tube cl2, near the outer end thereof, and passes through an eye Z, secured to the upper side of the bell on the front side of the central tube 7o (Z3. The free end of the lifting-lever, which is provided with a thumb-piece, is arranged ou the front side of the side tube D and behind a catch M, which is secured to the front side of said tube. This catch is preferably constructed of wire and is provided at its upper and lower ends, respectively, with forwardlyprojecting bent portions, forming indentations or recesses fm m', in which the liftinglever engages at either extreme of its move- 8o ment, and whereby it and the globe are locked in position. This lever is preferably made of spring-brass or other elastic material and so formed that in its normal position it will engage with its free end in one of these depressions, as represented in Fig. 4. Upon pressing the free end of the lever back, as represented in dotted lines in Fig. 4, the lever is disengaged from the indentation and can then be raised and lowered on the catch. When 9o the lever reaches the indentation at the opposite end of the catch, it enters the same, and

is thereby locked in position.

This lifting device is very simple in construction and locks the globe-frame securely in either of its extreme positions when resting on the burner or when elevated to give access to the burner.

I claim as my invention- 1. The combination,with thelantern-frame roo frame to the opposite side and connected between its fnlcruin and its free end with the upper portion of the globe-frame and an upright catch secured to the lantern-frame ad jacent to the free end of the lifting-lever and provided with an upper and a lower stop, with either of which the lifting-lever can be engaged, substantially as set forth.

fitness my hand this 5th day of October,

JOHN GALL. Vitnesses:
