LANTERN.

SPECIFICATION forming part of Letters Patent No. 415,693, dated November 26, 1889.

Application 'llerl August 2, 1889. Serial N0.3l9,510. (No model.)

.To all whom it may concern,.-

Be it known that I, ALFRED L. BARON, a citizen of the United States, residing at Tiffin, in the county of Seneca and State of Ohio, haveinvented certain newand usefulImprovements in Lanterns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a lantern of the class in which the globe may be raised away from the burner without complete detachment whenever access to the wick is desired. Heretofore alantern of that general class has been made with a lever to lift the globe directly upward, as shown in United States Patent No. 325,210. A lantern of that class has also been made with a lever pivot-ed at or near the base to lift the globe and swing it to one side at its lower end away from the burner; but a lever is obj ectionable,because it is a kind of supernumerary element in a lantern, and it generally projects so as to be in the way.

An important object of my invention is'to provide a lantern the globe of which has a hinge-connection at its lower end with the base and can be raised vand its lower end swung to one side without the use of a lever. In other lanterns of the general class above mentioned the globe is hinged to the base to rock to one side, the upper end being originally free from the main frame or detached therefrom to permit such rocking. In such case the globe and its frame become a long lever acting upon the hinge-axis, which is one of several objections to this form of construction.

A second important object of my invention is to so connect the globe to the base that it may be swung bodily to one side, exposing the burner, while its upper end remains in engagement with the stationary parts of the lantern. In thus at once dispensing with the lever and at all times holding the globe at each end I simplify and improve the construction of lanterns of the above general class.

In the accompanying drawings, to which this specification refers, Figure l shows the lantern with one of the sides tubes broken away, the globe being shown in full lines in its normal. position and in dotted lines in its position when displaced. Fig. 2 is a partial View looking in the direction of the arrow of Fig. l. Fig. 3 is a section on the linea', Fig. l, the view being downward and a part of the globesupporting cup being broken away. Fig. 4 is a partialsection on the line y y, Fig. 2.

In the drawings, A B C are respectively the base, the tubes, and the globe of an ordinary lan tern, having the usual burner D, central tube E, and globe-retaining clip G, none of which, separately considered, possess any novelty herein claimed. The globe is supportedkby a cup I, of somewhat unusual form, and is protected by guard-wires H, that are attached to the shield in the usual manner, and that pass from the shield F downward in the same plane upon opposite sides of the globe to the bottom of the cup, where they are bent inward in the same line and secured in bearings L, either stamped out from the bottom of the cup or soldered to its lower surface. The usual horizontal guard-wire ring H is secured to thesewires by soldering, and great strength of union is secured by carrying thc ring-wire some distance upward in contact with the wire II and returning it in the same manner, so that the surface for the attachment of the solder isvery greatly increased without increasing the amount of the latter. The shield with its clip, the cup, the globe, and the guard-wires move together as one whole, the shield sliding .upon the usual short central vertical tube E, and for convenience in lifting them a handle-loop J is provided. The cup has a central aperture adapting it to Iit overand restupon the burner,which thus supports the movable whole above named. To securely retain this whole while permitting it to be readily raised and swung to one side, fully exposing the burner, there is provided an oblique link K, broad enough to pass freely over the burner'and long enough to reach from a point near one 'edge of t-he cup to a point at some distance from the burner and upon its opposite side. At the first of these points the link is loosely held in a bearing 7 upon the lower side of the cup, and at the second point it isn in like manner revolubly secured in two distinct bearings M upon the base. It may then swing upward IOO upon an axis passing through these two bearings; but it is prevented from swinging in the opposite direction by the resistance the burner offers to further motion of the cup. Such upward motion, if the link be of proper length, will evidently raise the cup and swing it to one side, fully exposing the burner,l and it is immaterial whether the force applied tend to raise the cup directly or to displace it laterally, for if it move at all it must be in the path fixed by the link.

To prevent accidental displacement of the v globe and to retain it when carried out of position, other devices are necessary. Between the bearings M the link is bent out of the axial line to form a crank O, and upon this crank rests at all times a preferably fiat spring P, fixed to the base and provided with a short inward bend Q. This bend normally falls just. at one side of the crank, and as the spring constantly presses downward with some force it strongly resists rotation of the link in its bearings; but if the force applied be sufficient the spring yields and the crank passes to the opposite side of the bend, which then in like manner resists its return. Now the parts are so arranged that the crank is thus carried from side to side of the bend as theI globe is y carried out of position and returned thereto,

and hence the globe is held firmly at either limit of its path.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the base, the burner, and the globe-supporting cup resting upon the burner, of the link pivotally attached to boththe base and the cup and provided with the crank-like offset, and the spring pressing upon said offset, whereby the link is held against accidentaldisplacement when at eitherlimit of its path.

2. The combination, with the base supporting the usual central and lateral tubes, of the shield sliding and rocking upon the central tube, the globe and globe-supporting cup, the oblique link having its ends pivotally ati tached, respectively, to the base and to the f cup, the crank-like offset in the lower end of the link, and the spring resting upon the offset and provided with the bend to be passed vby the offset when the link is rotated, substantially as and for the purpose set forth.

In testimony whereof I afx my signature in presence of witnesses. s ALFRED L. BARON. IVitnesses:
