Specification of Letters Patent.

atented Apr. 18, 1911.

. Application filed December 8, 1910. Serial No. 596,381.

To all whom it may concern: 7

Be it known that I, Janus ll. lllLL, a citizcn ot the United States, and resident of Rochester, in the county of Monroe and,

required for the purpose of lighting the lan-' tern or cleaning the burner.

The object oi the invention is to produce aTdevice of the kind in question in which a hearing and a catch or detent of simple, inexpensive and rigid form are provided for the litterdever, and to this end the invention consists in the device illustrated in the accompanying drawing and hereinafter specifically described, as the same is delined in the succeeding claims.

In the accompanying drawings: Figure 1 is a front-elevation oi the lower portion ot a tubular lantern provided with a globeliit'ter embodying the present invention; Fig. 2 is a vertical section on the line 2-2 in Fig. 1, looking fromleft to right in the latter figure; Fig. 3 .is a planview of the parts shown in Fig. 2; and Figs. t and 5 are views similar to Figs. 2 and 3, respectively, showing a modified form of the invention.

In the illustrated embodiment of the invention the general form and operation of the globe-lifter are substantially the same as in the case of the type of the lobodi ttcr disclosed, .t'or example, in the patent to J. ll. i chlally, No. ($12,505, dated October 18.

i898, and familiar to those skilled in the art.

This litter comprises, as is usual in such constructions, a cranked lilterdover 3 journalod on the lantoripiran-ui and baring pivolal connections (not shown) with i'il(5 L1 'l\Jl) 3' plate. lithe present invention reside; in the l'5\')lii-3lll'lllliil0ll by which are provided a jonr- 1nd tor the portion of the liltcikdercr adjacent to the o]ierating-arin. and a rah-h or dctcnt for retaining the oporatinn-aria in depri-sscil positi n and the globe in raised position. it round stud or pin i is fixed horizontally in one ol' the side-tube oi: the lantcrn-frame, this pin being s Ill'liil therein in any convenient manner, but prettends inwardly from the tube 5, and the lifter-lover 3, which is formed, in the usual manner, oi" still' but somewhat flexible wire, has a coiled portion (3 loosely surrounding the bearing-pin so as o mount the litterlever pivoially thereon. Apart from this coiled portion the lifterd'ever is of the usual form, having an operating-arm 7 extending upwardly from the bearing-pin and terminating in a loop which may be conveniently operated by the thumb of the user of the lantern.

The detent by which the opcratii'lg-arm is retained in depressed position is embodied in a plate 8 which is :ixed to the inner end of the bearingpin 4. in the simplest form of the device, as illustrated in Figs. elund 5, this detent-plate consists of a disk of sheet metal which is rigidly secured to the bearing'pin, the pin having a squared portion to prevent rotation of the plate thereon and being upset at its extremity t) to retain the detent-plate .in place. The detent proper 10 is formed by an otl'set or bent portion of the plate which projects outwardly, that is, toward the side-tube 5, into position to be engaged by the operating-arm 7. The flexibility ,of the litter-lever is such that When the arm is depressed it may spring outwardly enough to pass the detent, until it assumes the position shown in dotted lines in Fig. 4. in this position the operatingarm rests entirely beneath the dotcnl', so that it is retained in depressed position thereby, until sprung outwardly by the user sullicicntly to permit it to pass upwardly over the detent, when the globe is to be lowered again.

'lhe titJllfaiIlltfilOll just described is simple and imixpcnsivc, but produces a rigid bear in; and dctont tor the litter-lever. 'lhe coiled portion of the lever, in addition to furnishing a bearing; to coi'iporato with the bearing-pin, has the 'iurthcr adi'aniiigtthat it increases the rcsilioln-y ot' the lever so as to facilitate the coiipcration ot' the lever with the detent.

Where a parl i-ularly rigid constru tion is desirable the dotont-plate may be pnohin the form illustrated in Fi e. l. :5 and $3. in this case the plate has a portion ll which is bent outwardly and shaped to til against the curred inner surface of the tube, being also extended upwardly. as shown in Fig. 5.,

erahl lo solderino". The bearhwiin cxso as to produce a lon beariu between the J c: f) a n I plate and the tube. This porlionll of the plate is preferably soldered to the tube, and thus a Very rigid and strong construction is produced.

I claim:-

1. Incombination with a tubular lantern having a cranked globe-lifter, a straight bearing-pin, upon Which the globe-lifter is pivotally mounted, fixed to and projecting inwardly from a side-tube of the lantern, and a plate fixed to the inner end of the bearing-pin and having an outwardlyconvex marginal projection cooperating with the globe-lifter and constituting a detent therefor.

2. In combination with a tubular lantern having a cranked globe-lifter, a bearing-pin for the globe-lifter fixed to and projecting inwardly from a side-tube of the lantern, and a plate connecting the side-tube and the inner end of the bearing-pin and having a projection cooperating with the globe-lifter and constituting a detent therefor.

3. In a tubular lantern, the combination of a side-tube, a bearing-pin projecting inwardly from the side-tube and provided at its inner end with a detent-projection, and a cranked globe-lifter having a portion coiled around the bearing-pin and an operatingarm cooperating with said detent-projection;
