LANTERN.

SPECIFICATION forming part of Letters Patent No. 366,020, dated July 5,1887

Application filed August 10, 1885. Serial No.173,966. '(No model.) I

To all whom it may concern.-

Be it knownthat 1, JOHN \V. ORPHY, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and usefullmprovement in Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of a lantern showing my improvement. Fig. 2 is a crosssection of the samein line 0000 ofFig. 1, looking down upon the globe holding disk. Fig. 3 is a vertical section of Fig. 2 in line y y. Fig. 4 is an elevation of a fragment of one of the side tubes, showing the means for raising and supporting the globe. Fig.5 is a section in line zz of Fig. 1.

My improvement relates to side-tube lanterns, and more particularly to the devices for raising and supporting the globe above the burner, so that thelatter can be easily lighted.

The improvement is as follows:

A indicates the fount or oil-pot;-B B, the side tubes; 0, the globe or chimney; D, the globe-supporting disk, and 'E the bell orholder for the top of the globe. The bell has atube, (1., which slides up outside the tube 1), to which the top of the side tubes are attached, andthis exterior tube, a, is pressed down by a coiled spring, a. The construction above described is common in lanterns.

The following features constitute my invention:

Gv is a rod or shaft having at its lower end a and at its upper end a finger-piece, f, by which it is raised. The mainportion of this shaftis a straight length, and rests in an eye or hearing, on the inside of one of the side tubes in such a manner that it can be slid up and down vertically, and can also be turned around axially, for apurpose presently to be described. The loop (1 at the lower end is of such size as to form a base to the globe-supporting disk D, and also to fit loosely over the top of the cone H, and when in place it rests on top of a square shoulder, h, Fig. 3, of the-cone, and holds the latter in place. is a bearing consisting of a flat strip with a wedge-shaped lower end, which heat of the lantern.

is secured to the inside of the side tube a little distance abovethenpper end oftherod G andin line with it, as clearly shown in Figs. 1 and at. \Vhen in place, the globe rests between the disks D E, and the cone is held down by the pressure of the globe resting on it. To raise the globe,the thumb is placed under the lugf of the rod G, and sutficient pressure is applied to slide the rod up through the bearing lawith the globe and holder attached, and overcoming the pressure of the coiled spring 0 at the.

top or" the lantern. As the rod rises its upper free end strikes the wedge-shaped bearing k, which springs it slightly outward without impeding its upward movement, and thefriction against this bearing is sufiicient to hold the globe elevated at any point if the hand is re leased. If desired, a spring-catch of any desired form can be used at the top to catch and hold the rod. i

One advantage of this invention is a single rod, located at one side on the side tube, hav ing a freesliding movement, by which the hand in raising the device is removed from the great Another and particular advantage is the use of such a rod at the side, fitted in an eye or bearing-so that itcan beslid up and down vertically and capable also of being turnedaxially. The object of this is so that when the globe is removed from the lantern and the globe-holder D is raised above.

and clear of the burner it can be swung oft entirely to one side of the burner, as indicated by the dotted lines, Fig. 2, thereby leaving the whole top of the burner free and exposed, by which means theparts can be readily separated for cleaning or otherwise. This is important in cleaning the lamp from dust and char which collect there, and which are not readily removable where the globe-holder is simply raised but cannot be swung off to one side. By this construction, also, the globe can be readily removed without raising the globeholder D from the cone H, since the dome can be raised indepenpently; whereas in some other lanterns of the kind the upper and lower disks that inclose the globe are tied together by rods and both must be raised together.

I is a finger-piece attached to the outer tube, a, that slides over the inner tube, I), at the top disk, D, as before described, and therefore the globe can be applied or removed without removing the disk D from the cone. The shaft p, passing through the slots, forms a guide to the top in moving up and down, and also prevents turning. 'I claim 1. The combination,with the burner and side tubes of a tubular lantern,of the globe,a dome at the top, and the holder or plate at the bottom, the single rod supporting the bottom plate and extending upward, the bearing on the side tube for the rod, and the thumb-piece at the top of the rod,said rod and bearing being adapted to permit a turning motion of. said rod on its longitudinal axis, whereby the plate may be turned away from the burner, substantially as described.

2. The combination,with the burner and side tubes, of the globe, the plate on which it rests, the rod secured to the plate, a catch or holding device on one of the side tubes, a bearing for said rod,with which said rod engages, and

athumbpiece on the rod, serving both as a means for .lifting the rod and plate and for disengaging the catch, substantially as described.

3. The combination,with a tubular lantern, of the perforated plate for supporting the globe, the rod to which it is secured, abearing for the rod, attached to one of the side tubes, in which it can be moved vertically and also rotated, and a catch with which said rod engages for holding it in elevated position when desired, substantially as described.

4. In' a tubular lantern, the combination, with the lamp, side tubes, spring-pressed bell guided on the dependent central tube, the globe, and the perforated plate supporting the globe and resting loosely upon the burner, the lifting-rod supported by guides on one of the side tubes, said rod being provided with a thumbpiece and attached to the perforated plate on which the globe is supportedgvhereby the globe and bell can be elevated against the pressure of the spring by the action of the lift- 1 ing-rod on the perforated plate, the globe when relieved from the pressure of the spring and bell can be turned to one side of the burner, and the hell can be raised independently to release the globe, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
