LANTERN-GLOBE LIFTER.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, "VILLIAM C. EM- BURY, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Lantern-Globe Lifters, of which the following is a specification.

This invention relates to globe lifters, such as are used in connection .with tubular lanterns of ordinary form, of the type in which a cranked lifter-shaft provided with a finger-lever is pivotally connected with the globe-plate of the lantern and is journaled on, or adjacent to, the side-tubes of the lantern.

The invention relates particularly to the member constituting a bearing and a detent for the lifter-shaft, and the object of the invention is to produce a device of this kind, capable of being formed of a single piece of sheet-metal, which shall besimple and rigid in structure and neat in appearance.

To this end the invention consists in a globe-lifter having the combined catchplate and bearing hereinafter described, as it is defined in the succeeding claim.

In the drawings :Figure 1 is a.frontelevation of the lower portion of a "tubular lantern provided with the present inven- 1 tion; Fig. 2 is a front perspective view of a portion-= of the globe-lifter, including the combined catch-plate and bearing; and Fig. 3 is a perspective view of the same parts from the rear.

The invention is illustrated as employed in connection with a tubular lantern of ordinary form, and in Fig. 1 portions of the lantern are illustrated, including the oilfont 4, the burner 5, the lobe 6 and the side-tubes 7 and 8. The -iigure also illustrates a cranked lifter-shaft 9 constructed of resilient wire and of the ordinary form, which is attached to the globe-plate 10 by the usual pivotal connections (not shown). The lifter-shaft 9 is provided at its righthand end withthe usual upwardly-bent finger-lever 11 which is arrangedv to lie between the side-tube 8 and the globe.

. The present invention resides particularly in the form of the combined catchplate, bearing and bearing-support for the shaft 9. This device comprises a vertical plate 12 which is perforated to receive the shaft 9. As shown in Fig. 3, the plate 12 is slotted inwardly from its edge to the perforation, thereby producing a tongue 13 which may be bent aside to admit the shaft and afterward bent back to close the hearing. The bearing-plate 12 is formed integral with a vertical side-plate 14 which connects one lateral edge of the bearing. plate with the side-tube 8 of the lantern. The side-plate 14 is preferably secured to the tube by soldering. A third portion of the bearing-support consists in a bottomplate 15 which extends inwardly from the lower edge of the bearing-plate ,to the sidetube and 1s soldered to the tube. The bottomplate 15 is also preferably integral with the bearing-plate and is joined to the lower edge of the'side-plate 14. The joint 16 between the plates 14 and 15'may be formed either by stamping these par-ts from a continuous piece of sheet-metal, or by uniting their edges by means of solder.

The catch-plate consists in an upward ex tension 17 from the side-plate 14. This catch-plate has, at its lower extremity, a shoulder 18 beneath which the finger-lever 11 is. retained when it has been depressed by the operator to raise the lantern-globe. Above the shoulder 18 the catch-plate has a long inclined cam-surface 19 over which the finger-lever. rides easily while being depressed. The lifter-shaft 9 is resilient, and

the finger-lever presses outwardly against the catch-plate, so that it is retained below the shoulder 18 until the finger-lever is pressed inwardly by the operator to release it. In the normal position of the parts the finger-lever is also retained in raised position by its engagement with the upper end ofthe catchplate.

The arrangement, at rightangles, of the side-plate 14 and the bottom-plate 15 by which theibearing-plate is supported produces a very rigid structure in which vertical strains are resisted eflfectively by the side-plate 14, while horizontal strains are resisted by the bottom-.platel5, since these plates lie with their {greatest dimensions in these two respective directions. The boxlike form produced by the plates 12, 14 and 15 also conduces to the substantial and or namental appearance of the device, while at the same time the device can be con- Patented May 16, 1911.

structed by a'minimunrlnuinber of operation, and can be readily and firmly secured to the'side-tube by means of solder alone.

I claim In combination with a tubular lantern, a globe, a globe-lifter comprising a cranked lifter-shaft connected with the globe-plate of the lantern and provided with a fingerlever located between the globe and one of the side-tubes of the lantern, and a combined bearing and catch-plate tor the liftershaft comprising a vertical bearing-plate located between the globe and the fingerlever and perforated to receive the liftershaft, a bottom-plate connecting the lower 15 edge of the bearing-plate with the tube, a vertical side-plate arranged at a right angle with the bottom-plate and connecting a lateral edge of the bearing-plate with the tube, and a catch-plate above the side-plate 20 \VILLIAM C.
