GLOBE-LIFTING DEVICE FOR LANTERNS.

Specification of Letters Patent.

.catenteol June 12, 1906.

Application filed Iuly 21.1905- Serial No. 270,656-

To all whom if may concern:

Be it known that I, ALBERT R. PRITCHARD, a cltizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Globe-Lifting Devices for Lanterns, of which the following is a specification.

This invention relates to globe-lifting devices for lanterns; and it consists in the apparatus hereinafter described and claimed.

In the drawings, Figure 1 is an elevation of a device embodying this invention. Fig. 2 is an elevation of the lower portion of the same device, showing the parts in a different position. Fig. 3 is a partial view showing the globe-lifting lever and the globe-plate in the same position as in Fig. 1, but from a different point of view; and Fig. 4 shows the same parts and in the same position as in Fig. 2, but from a difierent point of View.

In the drawings, 1 is the oil-pot.

2 is the gallery.

3 is the burner-cone.

4 is the globe-plate.

5 5 are the air-tubes.

6 is the spring-holder for the upper end of the globe 7, actuated by the spring 8. (Shown in dotted lines.) The downward pressure of the spring 8 forces the globe 7 against the globe-plate 4. The tubes 5 are connected at their upper ends to the casing 9, within which the spring 8 and globe -tube 6 are set, and said side tubes are connected at their lower ends to the gallery 2. In order to release the globe and remove it from the lantern, the globe-tube 6 is raised against the force of the spring 8 until the upper end of the globe can be slipped out laterally from said lobe-tube. In order to lift the globe and g obe-plate for access to light the lantern, lever means are rovided for lifting the globeplate, globe, an globe-tube6 against the force of the spring 8. For this purpose a wire 10 is employed, pivoted at its ends 11 1 1 in a portion of the frame of the lantern, such as the side tubes5 5. From the pivotal ends 11 the wire is bent so that there is a middle portion 12 out of the line of the pivots and which middle portion is held to the globe-plate in any suitable manner, such as by the loop 13. The said middle portion 12 is bent or curved so as to pass around the burner-cone 3 and not to make prejudicial contact therewith. At one end of the wire 10 is formed a handle 14,

preferably from the end of the Wire itself, the said wire bein bent first into the shape of said handle, an then the extremity after the formation of the handle constitutes the pivotal end 11 of said wire at that end thereof. The pivotal end 11 at the end having the handle 14 extends into its perforation and is of such length (see dotted lines, Fig. 1) as to permit it to spring inward and outward in its socket 15 in the side tube. Adjacent to the position of the handle or of the wire 10, adjacent to its pivot 1 1 on that end, is the catch-plate 16, having the long bevel 17, along which the said adjacent wire slides in passing from the normal position (shown in Fig. 1) to the lifting position, (shown in Fig. 2,) and when in the latter position the said handle-wire sprin s under a face 18 of said catchplate. In or or to cause an easier operation of the device, the handle proper 14 is bent at an angle of about forty-five degrees to the adjacent arm 19 thereof. The result of this position of the handle 14 is that the tendency is to place the thumb flat against it, and upon pressing, when in that posltion, the pressure forces the arm 19 out of engagement with the catch-plate 16 or reduces the pressure of such engagement, so that the lifting device is released from its position shown in Fig. 2, or in moving it from the position shown in Fig. 1 such movement is made easier. It is obvious that on tilting the lantern from the position shown in Fig. 1 to that shown in Fig. 2 access is given to the burner for lighting or for extinguishing the flame.

What I claim 1s 1. In a lantern, a lantern-frame comprising side tubes, a globe-plate, a globe, means for holdin the globe on the globe-plate, and a globe-1i ing device consisting of a bent elastic lever connected to the globe-plate and having ends pivoted in the inner sides of the side tubes out of line with its connection with the globe-plate and also bent between said ends to form an arm adjacent to one of the pivots, and a catch-plate projecting inward from one of the said tubes With which said arm engages.

2. In a lantern, a lantern-frame comprising side tubes, a globe-plate, a globe, means for holding the globe on the globe-plate and a globe-lifting device consisting of a bent elastic lever connected to the globe-plate and having ends pivoted in the inner sides of the press said bent lever for releasing the arm side tubes out of line with its connection with from the catchlate or for making easier 10 the globe-plate and having an arm adjacent movement over t e same.

to one of the pivots, a catch-plate with which said arm engages, and a thumb-piece on said ALBERT PRITCHARD arm extending outwardly therefrom and at Witnesses:

an acute angle thereto, whereby the tendency D. GURNEE,

of pressure on said thumb-piece is to co1n- L. THoN.
