ELECTRIC POCKET LAMP.
APPLICATION FILED mm. 1915.

JOHN STOCK, OF DUNTON, NEllV YORK, ASSIGNORTO TNTERSTATE ELECTRIC NOVEL COMPANY, OF NEW YORK, N. Y.', A CORPORATION OF NEW YORK' ELECTRIC POCKET-LAMP.
Application filed April 2, 1915. Serial No. 18,685.
To all whom it may concern:
Be it known that 1, JOHN S'rooK, a subof the Emperor of Austria-Hungary, residing at Dunton, Long Island, Queens county, State of New. York, have invented certain new and useful Improvements in Electric Pocket-Lamps, of which the following is a full, clear, and exact description. This invention relates to an improvement in electric pocketlamps,' but pertains more particularly to a circuit closer for such lamps to complete the circuit between the battery and the lamp.
The class of pocket-lamps to which my improvement is more particularly applied isof that type consisting of 'a tubular casing arranged to retain an electric, battery and lamp, the circuit for said lamp being closed by means arranged for manipulation exteriorly of the casing.
I will now proceed to. describe my inven-' -tion in detail, the essential features of which will be summarized in the appended claims, reference being had to the accompanying drawing, forming part hereof; wherein Figure 1 is a side elevation of a pocketlamp embodying my improvement: Fig.2 is arear elevation thereof; Fig. 3 is an enlarged fragmentary side elevation, partly in section, of one end'of the device; Fig. 1 is sectional view of the bushing which carries the contacts for the lamp circuit; Fig. 5 is a sectional View, the section being taken on a.line-55 in Fig. 3; and Fig. 6 is a frzigmentary side elevation showing a modified form of'my invention.
eferring to the drawing, the casing of my improved lamp is indicated by 1, within which is mounted the usual battery 2 which supplies current for a lamp 3. One leg of the circuit consists of the. casing 1 with which the lamp 3 is placed in circuit in. the
usual manner. Theother leg of the circuit for the lamp is completed ,by a circuit-closer in circuit with a spring 4 which,'at one end bears against one end of the battery 2. The
other end of the battery bears against the end of the lamp 3 as is usual in this type of lamp. J My improvement pertains more particularly to the circuit-closer and mounting for y the contact-spring .4. It is usual to placev a contact-spring, such as 4, 'i'n-one end of a casing and to have a battery bearing against sald spring;'but to more fully insulate the spring from the casing I provide a rubber or fiber bushing 5 having a pocket 6 which retains the spring 4, the said bushing being inserted in the open end of .the casing, as shown in Fig. 3, and held therein by a setscrew 7.
To convey the current from the spring 4 to the circuitcloser, I'provide a conducting strip 8 having one of its ends located in the pocket 6, the other end being bent upwardly, as at 9, to forma stop or contact, the-said contact being located in a recess 10 cut in the wall of the bushing 5. '(See Figs 3 and 4:). To close the circuit between the casing 1 and battery, I provide a metallic circuit-closer 11 which is arranged to-be moved longitudinally of the casing 1, the
said 'circuitcloser being mounted upon or earned by the flattened portion 12 ofthe bushlng 5, the inner end of the circuit-closer Patented @ct. at, was,
11 being bent inwardly to form a contact 13 to engage the contact 9 on the conductor 8.
The opposite end of the circuit-closer 11 is passed through an opening 13 in the casing 1 and extends beyond said opening sufliciently to enable one to operate same. To
facilitate operating the circuit-closer 11, a
When the circuit-closer is pushed or moved outwardly the contacts 9 and 13 will come together, thereby closing the circuit forthe lamp .3. When the. circuit-closer is pushed inwardly,-the' circuit, for the lamp will be.
opened.-- The circuit-closer-ll is not in any way secured or connected to the casing, but
is free to be moved longitudinally thereof,
a portion of the circuit-closer being within the casing and the remainder located exteriorly of the casing.
To hold the lamp in a pocket I'may employa clip, such as indicated by 15 in Fig. 1'; or I mayextend the circuit-closer 11'suf ficiently beyond the opening 13 to provide a resilient clip 16 as shown in the modified form of-my mprovement illustrated in Fig. 6. In this latter instance a roundedhead .17 will be located upon the under. surface-of This latter --forin of my inventionapoS the advantage. of automatically npeningt the clip 17 to" bear "against thejcasing placed in apocket, for the reason that the action of forcing the clip over the material" or the pocket, will more the circuit-closer rearwardly, thereby opening the circuit fpr the lamp 3; It will also be seen by referring to Figs. 3 and 4 that the bushing 5 is provided with a counterbore 18 to receive the inner end of the battery 2. By this means the battery is'prevented from lashing in thecasing and thus breaking the covering .thereof, which is usually of relatively thin paper. Furthermore the counterbore 18 acts to keep the battery 2 and spring 4 in v alinement.
Having now described my invention what I claim and desire to secure by Letters Pateiit is: a I I y l. A pocket-lamp, consisting. of a casing, a lamp located at one end thereof, a battery within said casing but insulated therefrom and having one of its ends in contact with said lamp, the other side of the'circuit for said lamp being through said casing, a bushing of insulating material located in the opposite end ofsaid casing, a spring within said bushing bearing against the adjacent end of said battery, a longitudinally slidable circuit-closer located between said bushing and-said casing and one end of which extends exteriorly of the latter, andmeans to conduct current from said spring to a point 2 adjacent said circuit-closer.
