HANDLAMP.

Application filed April 2, 1921.

Z '0 all whom it may concern:

Be it known that I, ARTHUR A. AnNoLo, a

-. citizen of the United States, residing at 'I-iartford, county of Hartford, State of Connecticut,-have invented certain new and useful Improvements in Handlanips, of which the following is a specification.

My invention relates to hand lamps and more particularly to electric hand lamps which are usually provided with the ordinary type of light bulb and are adapted to contain a battery of dry cells or some suitable source of electric current. Such lamps are usually called flash lights and the bulb is adapted to be placed in circuit with the cell or cells of the battery by the operation of a switch conveniently located at the exterior of the casing for manual operation.

The invention has more particular reference to a lamp of this type in which a tubular casing is employed to house the batteries or cells and wherein a metallic switch structure is applied to the exterior of the casing melilnber to. control the operation of the li t.

In the past it has been found difficult at times to carry such a lamp in a convenient manner, due to the shape and size thereof and, moreover, it has been found diflicult to place the lamp in a stationary position upon a table or the like so that a satisfactory disposition of the same may be made when not in use. Theshape of the lamp usually is such that it is apt to roll when placed upon a flat surface and, moreover, there are no projections or protuberances usually provided by which the lamp may be supported or suspended in a convenient manner. It, is to obviate these disadvantages that my invention is particularly designed.

One object of my invention is to providea means attached to the lamp casing whereby the lamp may be easily carried either in or out; of use and may be conveniently disposed of when it is not desired to carry the same. This is accomplished in the particular form of my invention shown in the drawings by the provision of a flexible supporting member which is attached to certain portions of the casing and by which the lamp may be suspended.

A further object of my invention is to 'attach such a supporting member to the lamp in a convenient, economical, and satisfactory manner so that it will not interfere with the Serial N0. 457,898.

operation of the lamp or will not cause a short c1rcu1ting of the same so as to cause the lighting of the bulb at times when a light is not desired.

A still further object of my invention is to connect such a supporting member to one of the circuit controlling members of the lamp sothat this member may be operated thereby in a convenient manner.

Tothese and other ends the invention conslsts 1n the novel features and combination of parts to be hereinafter described and claimed.

In the accompanying drawing:

Fig. 1 IS a side elevation view of a hand lamp embodying the principles of my inventlon;

F g. 2 is a rear end view of the same;

Fig. 3 1s a detail plan view of a portion of the lamp showing the manner. of connectmg one end of the supporting member;

Fig. 4 is a sectional view Fig. 1;

Fig. 5 is a sectional view on line 5-5 of Fig. 1; and

Fig. 6 is a sectional view through the circuit controlling switch mounted upon the lamp casing taken substantially on line 66 of Fig. 3.

I have shown my improvements applied to a tubular hand lamp having a casing 10 of any suitable material which, as shown in the drawings, is of fibre or a suitable non-conducting material. The casing contains the usual dry cell or cells 11 and is provided at the rear end with the customary threaded ferrule 12 upon which is threaded in the ordinary fashion the base cap 13 which, as shown in the drawings, is of metal. The

usual spiral contact spring 14 is provided between the rear end of the battery and the metal base cap so that the current will be carried by this spring from the usual zinc cup containing the cell tothe metal base cap. A contact member in the form of a flat strip 15 is applied to the interior wall of the casing 10. the rear end of this strip being in contact with the metal ferrule 12 or the base member 13, and the forward end of the same being suitably riveted at 16 to a metallic escut-cheon 17 provided upon the outer surface of the casing.

The metallic escutcheon 17 serves as a current carrying member and has pivoted thereto. at 18 a. spring contact member 19 about the light bulb 22.

which is adapted to be depressed into contact with a second current carr ing contact strip 20 which extends forwardly into contact with the reflector 21 which is mounted This reflector, as shown, is formed of conducting material and is in contact with one terminal of the,

. result.

The escutcheon 17 has mounted thereon a circuit controlling member in the form of a sliding corrugated thumb piece 23 which may be moved backwardly or forwardly to control the position of the contact member 19. This slide 23 is suitably mounted upon the escutcheon and has provided below the surface of the same a lug 25 which normally rests within a slot in the contact member 19. When, however, the contact member 19 is depressed into engagement with the member 20, the sliding thumb piece may be moved forwardly so that this lug 25 will bear upon the surface of the member 19 to retain the same in depressed position and thereby lock this member in circuit closing position to cause a continuous light. lVhen the sliding thumb piece is moved rearwardly, the resilience of the contact member 19 will cause it to assume its normal position and the li hting of the bulb will be interrupted. 'ith the particular form of switch shown, it will be understood that the contact member 19 must be depressed before the thumb piece 23 may be moved forwardly to lock the same in its circuit closing position, although the exact arrangement of these parts will not be of importance in all aspects of the invention.

To provide a convenient method of supporting the lamp while both in and out of use, there is shown in the drawings a flexible supporting member in the form of a chain 26, one end of which is detachably connected to a contact member of the lamp by the provision of a hook 27 which is adapted to be passed through an opening 28 in the sliding thumb piece 23. This hook member is so arranged that it may be easily detached when desired. The other end of the supporting member 26 is passed through an opening 29 in the base cap of the case and is provided upon the portion lying within the case with a loop 30 which may be a portion of one of the links of the chain, in the form shown, through which is passed a 'portion of the contact spring 14.

This, it is seen, will provide a very convenient and satisfactory manner of securing this end of the chain to the lamp. As will be seen, the chain will be connected to circuit carrying members of the casing, but as the base can and the sliding thumb piece will be of the same polarity the connection between them formed by the chain 26 will not affect the operation of the circuit closin" members.

lVhen the base cap is removed for the insertion of new cells or for any other purpose, the forward end of the chain may be detached by the removal of the end of the hook 27 from the perforation 28 so that the chain will not be twisted by the turning of the cap. Moreover, this hook may be disconnected from the casing so that, if desired, it may be secured in the buttonhole when the lamp is carried in the pocket, so that all danger of losing the lamp will be avoided. The supporting member, it will be noted, is connected to the sliding controlling member 23 so that this member may be operated thereby. if desired. It is seen, therefore. that when the lamp is lightend, a rearward pull upon the supporting chain will move the sliding control member rearwardly so that the contact member 19 will be restored to the normal position shown in Fig. 6, and the circuit through the lamp interrupted. In the same manner the circuit may be locked in closed position by a forward pull upon the chain 26 after the contact member has been depressed.

Vhile I have shown and described a preferred form of my invention with particularity, it is to be understood it is not to be limited to the exact details shown, but is capable of modifications and variations which will lie within the spirit of the invention and within the scope of the appended claims.

It is apparent that a hand lamp provided with my improvements may be conveniently suspended from a nail or the like by its supporting member so that a convenient disposition of the same may be made when not in use. lVhen it is desired to use the lamp, the same may be carried the chain or sus pended from the wrist, if desired. A great many uses for the flexible supporting member will at once suggest themselves to anyone using the device.
