IMPROVEMENT IN POLlCE-LANTERNS.

Specification forming part of Letters Patent No. 157,641, dated December 8, 1874; application filed June 22, 1874.

To all whom it may concern:

Be it known that I, JAMES SHEEDY, of the city, county, and State of New York, have invented an Improved Police-Lantern, of which the following is a specification r Figure 1 is a vertical central section of my improved police-lantern. Fig. 2 is a horizon tal section of the same.

Similar letters of reference indicate corresponding parts.

This invention has for its object to simplify the construction of a police-lantern, so that the same will be cheaper and more easily operated than lanterns for similar purposes now in use.

p The improvements are fully hereinafter described and claimed.

In the accompanying drawing, the letter A represents the case or body, of my lantern. The same is arranged to receive a lens, B, in the ordinary manner, and has at its back a single or double handle, 0, in the usual style. D is the lamp placed within the case A, and. made with a suitable wick-tube or light-ho1der,a.. From the lamp D extends upward within the case A a rod, E, terminat ing in a loop or enlargement, c, at its upper end, said loop being above the top of the case A. A spring, I), which is fastened to the inner side of the case A, bears against the rod E, and serves to hold the same or the lamp D in the requisite position.

The loop 0, or other projection on the rod E above the case A, is so placed that when the lamp D is let entirely down, as shown by full lines in Fig. 1, it will not quite reach the perforated bottom at of the case A, leaving, therefore, ample space for an air-current from below to the flame, and making, consequently, the projections which were heretofore necessarily formed on the bottom d, to hold the lamp above the same, unnecessary. The cost of the lantern is thereby greatly reduced.

When the light of the lamp is to be hidden it is only necessary to draw up the rod E, thereby leaving the lamp within the case A, as indicated by dotted lines in Fig. 1, and bringing the light out of line with the lens.

By thus making the lamp vertically adjustable within the case A, the ordinary slide employed within such case to be interposed between the lamp and lens is also made unnecessary and dispensed with, and the cost of the lamp still further reduced, the spring I) holdin g the rod E at any suitable elevation.

The use of the sliding rod E, with its loop or enlargement 6, makes it also very convenient to elevate the lamp for hiding its light by means of the thumb of the same hand that holds the lamp, while hitherto it was necessary to use both hands for concealing the light.

F is the lid or cover of the case A. It is made of double truncated conical shape, and contains two conical corrugated caps, g and h. The cap h is within the body F of the lid, and the cap 9 above the same, both being con nected with each other by a central bolt, 6. This central bolt draws the lower cap h up against the inner side of the lid F, so that the outer portions of the corrugated surface of h rest against the inner side of F. At the same time the bolt also draws the upper cap g down upon the outer side of F, so that the inner ribs or corrugations g bear against such outer side of F. Thus the three parts, g, h, and F, are properly and firmly connected with each other by the said bolt 'i without requiring any other fastening, dispensing, therefore, with the ordinary process of riveting, which is expensive, and very difficult to apply on such corrugated surfaces. That the cap it is perforated for allowing the air to pass upward into the cap git is hardly necessary to specify.

A fourth advantage of my invention is that, by making the lamp vertically adjustable and attaching it to the rod E, I dispense with the gate or door which at present is always formed in police-lanterns of this kind,said door being in ordinary cases necessary for allowing the removal of the lamp from within the case.

It is evident that, instead of the spring-holder Z), holding devices of diiferent construction, though having substantially the same effect, may be used.

At the upper end or head of the bolt 13 is a wooden knob, K, by means of which the lantern may sometimes be held or carried, and which also facilitates the opening of the lid F. Being of wood, it does not become so but as the metal, and therefore causes less inconvenperforated cap h arranged within the lid, and

ience in handling.

I claim as my invention, and desire to se- -cure by Letters Patent 1. The combination of the casin gA,havin gthe lens B in one side, with the lamp arranged on the rod E, which projects through the top of the casing, and is vertically adjustable to raise the lamp above the lens, substantially as and for the object specified.

2. The combination of the lid F with the the cap g, arranged over the opening in the top of the said lid, the parts being connected together by the bolt a, which also serves to hold the handle K, in the manner and for the purpose herein described. I

JAMES SHEEDY.
