EPECIFICATION forming part of Letters Patent No. 314,657, dated .March 3l, 1825.
Application filed August 30, i384.
To all whom may concern:
Be it known that I, GEORGE C. DEEssEL, of the city of New York, in the county and State of New York, have invented a new` and Improved Lantern, of which the following specification is a full, clear, and exact description.
rlhis invention relates to an improved manner ofattaching lenses known as bulls-eyes, se1naphores,7 dto., to lanterns in such a manner that they are rcadilyinserted and removed.
The invention consists in the details of construction hereinafter more fully pointed out.
In the accompanying drawings, Figure lis a face view of a lantern provided with my improvement. Fig. 2 is a transverse section on the line w x, Fig. l; and Fig. 3, a detail view of the i'asteningwire.
The letter A represents alantern of suitable or customary construction. The face or front of this lantern has a large circular opening,which is surrounded by a backWardly-extending tapering flange, a. This flange is at its edge b bent inwardly to form a seat for a lens, B. The lens projects forward within the tapering angea, so that an annular channel isleft between llange and lens, as shown in Eig. 2.
d is a circular wire of a size to tit over the edge of the lens B and within the ilange a. This wire has preferably disconnected ends e, and these ends are bent outward to fit into two perforations in ange a.
f is a set-screw, springcatch, or similar (No model.)
fastening device attached to or passi ng through ange a, and adapted to be projected over wire d, so as to press it against the lens.
In use the lens B is placed upon its seat b, and the wire is then placed over the edge of the lens, with its ends extending through the flange holes. Next the set -screw f is turned until it projects over the wire. In this Way the Wire is held down at three points and constitutes a iirm locking device for the lens. a'
To remove the lens it is only necessary to turn the set-screw fback and lift the wire Out.
I prefer to pass the ends e ofthe wire through two separate holes in flange a, as shown, inasmuch as by this construction I obtain three contactpoints; but if only two contact-points are desired the wire may be passed through Vone hole only.
I claim as inyinvcntion 1. The combination of lantern A, having ilange c, with lens B, and with the wire having outwardly-bent ends e, that pass through a hole 'or holes in llange a, and with fastener f, substantially as specified.
2. The combination of lantern A, having ange a and seat b, with lens B, and wire d, having two outwardlybent disconnected ends, e, and with fastener f, substantially as herein shown and described.
