- TUB ULAR LANTERN.

To all whom it may concern:

Be it known that l, WiLmAM (,3. WIN FIELD, a citizen of the United States, residing at Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Tubular Lanterns, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tubular lanterns, and the invention consists in means for holding the globe guard and globe at any desired elevation so that the lantern may be lighted, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a lantern embodying my invention with one of the side tubes partially in section and showing the globe uard down on its seat. Fig. 2 is a vertical sectional elevation of a portion of one of the side tubes and one of the friction engaging devices for the globe guard and a portion of a side Wire of said guard engaged by said device and held as occurs when the globe is raised from its seat, as hereinafter fully described. Fig. 3 is a detail of one of the said friction engaging devices, and Fig. 4 is a lan view on line rc-a:, Fig. 1.

he invention is comprised in the arts thus shown and described and particiilarly in the means for frictionally engaging the side wires W of the globe guard or frame and thus supporting the said guard with the globe at any preferred elevation above its seat, assuming that such elevation or lift is sufficient to enable one to light the lantern with a match or taper. The said side wires W have a slight lateral or outward bend or depression 3 of approximately V shape in their lower portions adapted to engage the horizontal wire ll of the globe guard on their inside, and said side wires are straight and parallel or substantially parallel with each other from said bends 3 downward to the right angled bend 10, as seen in Figs. 1 and 2, and which straight portion is indicated by numeral 2. At their u 3P6? ends the said side wires W connect with the edge of the canopy (J by pivot as usual, and said canopy is slidably mounted upon the central draft tube D.

A feature in side wires W to be noted is Specification of Letters Patent.

Serial No. 449,516.

that said wires run at an inclination between the canopy and bends 3, while the lower portions 2 of said wires are offset inward somewhat at said bends and stand vertical from that point down to angle or corner 10, thus bringing the two portions of said wires into diifcrent vertical planes in side view and causing a distinct pull or draw to be made u ion the said friction members 1* when the globe guard is raised and the said members or devices are forced out of the recesses or bends 8 and into engagement with the straight wire portions 2 below the same. The outward bends or depressions 3 in the side wires therefore serve not only as a point of engagement with and for thehorizontal guard wire l' but also as a place of retire ment for the hook or loop 5 of the friction spring supporting members l To this end the said members or devices are preferably made of sprin wire fashioned to be bodily inserted into t 1e side tubes '1 of the lantern and have straight body portions 6, spring stems 7 and U shaped bends 8 connecting body and stem, whiletthe other end 9 is bent at right angles in the )lane of stem 7 and projects inward through a hole in the tube '1" and is formed with a hook 5 outside said tube and eng a ed over wire WV. In point of location said deep or hook comes almost directly opposite depression 3 in the side wire \V when the globe is down 11 on its seat, in use, and therefore is norma ly en aged or lies in said depression or bend just below wire 11 as a place of rest, and at which time its spring action is at its minimum. lhis appears by reference to Fig. 1, in which the globe is seated and the bodies 6 of said spring devices F are pressed back against the wall of the tubes and their hooks 5 are drawn back into said depressions 3 by the spring action of stem 7 bearing, against the opposite sides of said tube. On the other hand when the globe is raised, presumably in Fig. 2, the main portion (5 ol' the device is sprung outward. somewhat in its lower portion against the resistance of its own spring end 7 and the hook or loop 5 is carried down out of its retirement in bond 3 onto the straight portion 2 of the wire, where the friction is sufficient to hold the globe in raised position. Hence the globe is hold higher or lower by the said sprin r devices at any desired elevation by a sliding contact on a erfectly plain and straight surface. It wi be nojunction with the side wires W serve as lantern in point of appearances and keeps 5 of the said friction sustaining members F is with the wires W on the inner side and that suspension or support of the globe begins as soon as said hooks or loops 5 leave l tieed that the engagement of loops or hooks i l the depressions 3 and enter upon said strai ht portions 2. It is to be noticed, also, as a peculiarity of this construction that the 3 said spn'n members F are wholly ret [red within the si e tube of the lantern and hence entirely out of the way mechanically and out of sight except in their small and almost unnoticeable projecting portions 5. This both contributes to the attractiveness of the the main 0 eratin members within cover so as to avoi possib e injury by accident and ex osme to the elements.

11 the operation the tube 1) at the top and the friction membeis F at the sides in couguides for directing the said guard in dirert F up and down movements under such fl'lC- tional tension by the said members F that the guard is held u at any point of cngage- E ment on the stung itportions 2 of the guard Wires, and there is no special stopping point i necessary for the guard. What I claim is:- .1. A lantern having side tubes and a? globe-guard with vertical side wires, and i springs within the said tubes having ends 5 profeeting through the inner sides thereof an friet-ionally engagin said side wires. g ,f 2. A lantern having 51 0 tubes and a guard E with side wires, and a spring device confined i within each tube having engagement with l the corresponding side wire of the guard and adapt-ed to spring back and forth in the wall of t a tube. 3

3. A lantern having side tubes with holes through the inner sides thereof and a globe guard having side wires next thereto, in combination with springs local-ed within said tubes having sulmtnntinlly loop shaped portions extending out-ward through said holes and hnvmg sliding engagement with the said side wires.

4. A lantern having side tubes and a spring device confined in each tube having a portion extending through the tube, in combination with a globe guard having vertical side wires provided with bonds in their lower portions in sliding relation with said yielding portions of said spring devices.

.3. A lantern having side tubes, a device located in each tube having a spring portion at one end eouhued in the tube and a projection at the other-end extending through the wall ot the tube, in combination with a globe j guard having side wires provided with outward depressions and straight portions beneath said dqn-essions operntively engaged by said side proeotions.

.6. A lantern having side tubes and a central tube at its top, in combination with a globe guard and canopy slidably eng ed with said central tube, and guides l0('fli.6( in a said side tubes having spring stems at one
