FLASH-LIGHT.

Specification of Letters Patent. Patented Aug, 24, 191.5.

Application filed April 30, 1915. Serial No. 24,960.

and in its generic nature, the invention comprises 'a metallic'tube or sleeve adapted to be inserted into a bore of an umbrella handle or'sleeve having an enlargement in which a bulb carrier is mounted and over the end of which a lens is held by a screw cap, the outer surfae of which merges with t-he configuration of the handle to present an ornamental appearance and not provide'any projections that will interfere with the free use of the handle; the invent-ion also includes a special construction of circuit closer elec-F trically connected with the metallic sleeve and with one terminal of the battery, the

battery being held within and insulated from the metallic sleeve.

In its more detail nature, the invention includes those novel features of const-ruction, combination and arrangement of parts, all of which will be first fully described, then be specifically pointed out in the appended claims and illustrated in the accompanying drawing, nwhich:

Figure l is a perspective view of one form of umbrella handle with the invention applied. Fig. 2 isa cross section and part elevation of another form of handle, illustrating theinvention rapplied thereto. Fig. 3 is an enlarged detail sectional view of the front end of the same. Fig. 4 is an enlarged detail view of the rear end of the handle showing the circuit closer arrangement. Fig. 5 is a detail front elevation of a portion of the handle with the outer plate of the circuit closer removed. Fig. 6 is a` detail perspective view of the circuit closer plate. Fig. 7 is a detail perspective view of the contact spring carrying member.

In the drawings, in which like letters and numerals of reference indicate like parts in all of the figures, l represents that portion of the handle which is designed tov be grasped by the hand of the operator and 2 designates the shank of the handle. The handle portion 1 is bored at 3 from the free end toward the bend with a blind bore, the bore 3 being enlarged at the forward end, as at -l to provide a shoulder against which the shouldered portion 6 of the metallic sleeve '5 is designed to engage, the sleeve 5 being enlarged at 7 and having its front end designed to project bevond the front end of the handle portion l, as best shown in Fig. 3 of the drawing.

The enlarged portion of the sleeve 5 is provided with a flange 8 to abut the end of the handle portion l and is further provided with the threaded projection 9 designed to receive the lens cap 10 which is swaged over, as at 11, to hold the lens 12 clamped against the flange l-l of the bulb carrier' 13 and hold the lat-ter clamped against the end of the projection 9 of the enlargement-,7 of the sleeve 5.

vThe lamp carrier'13 is preferably of the reflector type and is provided with a reflecting surface 15 and the threaded bulb socket 1G in which the bulb base 18 is designed to be secured. 17 is the bulb and 20 designates the batteries. one terminal of which is designed to engage the usual Contact on the base 1 8 and the other terminal ofthe battery 20 is designed to be engaged by the coil contact springv 24, which also vfunctions to hold the battery 20 in contacting engagement.

The battery 20 is held within the insulat ing bushing or cover 19 so as to hold it out of contact with the metallic sleeve 5.

21 designates the rear or blind wall of the bore 3 against which the metallic `spring carrying member 22 is tacked, as at 25, the member 22 having the U-portion 23 which carries the spring 24 and holds it in position.

30 is the circuit closer chamber in the shank 2 of the handle and this chamber 30 is connected by a bore 27 with the rear end of the bore 3 to form a conduit through which the conducting wires 26-29 are passed.

The wire 26 has one terminal electrically connected to the member 22 by one of the tacks 25. or it may be soldered or otherwise secured to such member22 as may be -found desirable, the other -end ofthe wire 26 is tacked at 32 within the circuit closer chamber 30 at a position whereby the tack 32 will serve as one of the contacts of the circuit closer.

The wire 29 is soldered or otherwise suitably electrically connected at 28 with the sleeve 3 and it has its other end electrically connected with the circuit closer plate 33 by one ofthe tacks 40 that passes through the ear 34 (see Figs. 4 and 5).

The ci-rcuit closer plate 33 is designed to fit into a countersunk portion of the shank of the handle to close the chamber 30 and it is provided with apertures in the ears 34 and at the bottom through which the tacks 40 may be passed to secure the plate 33 in position.

3G designates a .contact spring of the leaf spring type that is soldered or otherwise suitably secured at its end 35 to the plate 33 and is provided with a button 38 that is secured at 39 and designed to pass through a hole 37 in the plate 33 whereby it may be conveniently engaged by the finger and pressed to bring the contact portions 39 and 32 into engagement to close the battery circuit.

From the foregoing, it will be noticed that we have provided a compact and neat arrangement specially designed for the purposes mentioned, which will not mar or detract from the appearance of the handle.

We further call attention to the fact that the invention may be employed on various kinds of handles and is -not confined to a handle of any particular ornamentation or configuration.

What We claim is:

1. In a flashlight, a handle having a blind bore entering from one end and enlarged at the entrance, a metallic sleeve fitted into said bore and including an enlargement at the outer end, said enlargement having a threaded portion projecting beyond the end of the handle, a c'ap threaded onto said projection, a bulb carrier held within said sleeve enlargement anda lens held against said bulb carrier by said "threaded ring, a battery mounted within said sleeve, an insulating covering for separating said battery from said sleeve, said handle including a shank portion having a chamber, a bore connecting said sleeve bore With said chamber, a current conducting wire electrically connected to said sleeve and passing through said bore into said shank chamber, a spring contact in said sleeve bore, said spring contact being electrically engaged with said battery, a current conductor electrically connected With said spring contact and projectingthrough said bore into said shank chamber, and a circuit closer to which said current conductors are connected, said circuit closer including a closer plate for said shank chamber, a contact maker on said closer plate,'a button carried by said Contact maker and projecting through a hole in said closer plate together with a fixed contact designed to be engaged by said circuit closer contact maker, substantially as shown and for'the purposes described.
