LANTERN.
SPECIFICATION forming part of Letters Patent No. 354,629, dated December 21, 1886.
Application filed April 9, 1886. Serial No. 198,2 4. (No model.)
To aZZ whom it may concern.-
Be it known that I, GEORGE O. DREssEL, a resident of New York, 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.
This invention relates to a new manner of attaching lenses known as semaphores, bulls-eyes, &c., to lanterns in such a manner that they are readily inserted and removed.
The invention consists in the details of construction, hereinafter more fully pointed out.
In the accompanying drawings, Figure 1 is a back view of one side of a lantern provided with my improvement. Fig. 2 is a transverse section on the line we, Fig. 1. Fig. 3 is a detail side View of one of the springs d.
The letter a represents one of the sheetmetal sides of a lantern, the same being provided with a circular opening that is surrounded by a flange, I), such flange constituting the seat for the bnlls-eye or semaphore c. To the back of the side a there are riveted two or more springs, d, the free ends of which bear V upon the lens 0. The springs d are of ogce form, as shown in Fig. 3, and thus their free ends are bent toward the glass, to press firmly upon the same.
6 is a third spring, pivoted by pin 9 to a plate, h, that is raised from and soldered to the back of plate a. The pin 9 is upset between plates a h, or is otherwise enlarged.
The spring a may be swung upon its pivot, so that its free end projects over or clears the lens. .Asto'pfl, limits the motionof the spring. In use the springe is swung clear of the opening within plate a. The lens is inserted in front of springs d, and then the spring e is swung down, as in Fig. 1, to confine the lens in place.
The plate h has a double use. It first raises the spring e well forward, so as to more readily pass over the lens; secondly, it receives the- GEO. O. DRESSEL.
