ELECTRIC LAM P.

SPECIFICATION forming part of Letters Patent No. 603,112, dated April 26, 1898.

Application filed October 9, 1897. Serial No. 654,660. (No model.)

To all whom, it may concern:

Be it known that 1, DAVID MIsELL, a subject of the Queen of Great Britain, and a resident of New York city, county of New York,

and State of New York, have invented certain new and useful Improvements in Electrical Lamps, of which the following is a specification, reference being had to the accompanying drawings, forming a part there- ID of, in which similar letters of reference indicate corresponding parts.

This invention relates to electrical bicyclelamps; and it has for its object to provide a simple and improved electric lamp of this character which will insure economy by providing against the unnecessary or accidental use of the current and which will furthermore possess advantages in point of direct contact, positive action, convenience, efiectiveness, adaptability, and general efficiency.

In the drawings, Figure l is a perspective view of a bicyclelamp embodying my improvements. Figs. 2 and 3 are vertical transverse sectional views. Figs. 4 and 5 are hori- 2 5 zontal sectional views.

Referring to the drawings, A designates a box or casing which is preferably of rectangular form and may be constructed of any suitable or adapted material. The casing is provided with a hinged back B, which will serve the double purpose of permitting ex amination of the interior and retaining the removable battery securely in position. This hinged back also enables the removal of the battery, when desired, for substitution or any other purpose. The hinged back is secured in closed position by a suitable catch 0, of any adapted construction, and when the device is used as a bicycle-lamp the hinged back may carry suitable attaching devices, as at D, for mounting the lamp in position upon the bicycle.

E designates the battery, which is arranged to fit the interior of the box or casing and 5 may be formed of any suitable number of electrically-connected cells. I preferably use a dry battery of any suitable form, and the battery is not fixed or attached to the casing, but is simply fitted or set therein, so that it can be conveniently and readily removed when desired.

The battery carries upon its inner or front face, preferably at about a central point, a contact-plate f, which may be in the form of a projecting spring-plate, as shown, adapted, when the battery is in position, to project against the inner end or contact-point g of an incandescent-lamp bulb H, which is inserted through the front wall a of the casing and is surrounded bya suitable reflector I of any preferred construction. The lamp-bulb is preferably adjustable by means of a threaded connection, as at j, in the opening a in the front wall of the casing, by which construction and arrangement it may be readily adjusted with relation to the contact-spring f to insure its positive bearing in connection therewith.

Extending upwardly from and in contact with the inner contact of the lamp-bulb is a conductor-plate K, which may be insulated within the casing from the inclosed battery, which plate is connected with a contact pin or post Z, exteriorly projecting at the top a of the casing. The post .1 is preferably in its exterior form of a shape corresponding to tack-head or small flat knob.

M designates an arched handle, which is journaled in suitable bearings, as at n 72, upon the top of the casing. One of said bearings n is connected by conductor 0 with a spring contact-plate P, arranged within the casing, preferably at one of the upper corners, and bowed, as shown at p. This spring contactplate P is adapted to bear against a contactplate q, arranged upon the inner or front face of the battery at one of its upper corners.

Upon the top of the casing are provided two bowed spring-plates 1' r, upon which bear gudgeons m m upon the ends of the handle, said gudgeons having square or angular sides, as at m m, by means of which relative construction and arrangement the handle is retained by the tension of said spring-plates either in a normal upright position or in a horizontal position in contact with the post Z.

The spring contact-plate f is in connection with one pole of the battery and also with the lamp, and from this connection the conductor K leads to the contact pin or post Z. The contact-plate q is inconnection with the other pole of the battery and in contact with the spring contact-plate P, from which extends the conductor or connection to the handle. Therefore when the handle is in normal upright position the circuit is broken; but when the handle is turned downinto horizontal position, so that it bears against the contactwith the casing the lamp may be readily adjusted to regulate its contact with thespringplate f, as desired.

Bymeans of the rectangular face-gudgeons bearing upon the bowed springs the handle is securely maintained in either of its two positions-that is, either in its normal upright position, when the lampwill be out of circuit, or in a horizontal position in direct contact with the post Z, when the lamp will be in circuit. Any possible jarring or jolting of the handle from direct and positive connection with the post [is thus obviated.

It will be understood that while my improved lamp is especially adapted for use as a bicycle-lamp it may be also effectivelyemployed as a photographers lamp or for any other purpose in which a simple and convenient lamp is desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An improved electric lamp, comprising a casing, a battery carried thereby, a lamp in connection with one pole of said battery, a conductor extending from said connection to a contact conductor or post exteriorly arranged upon the casing, a handle in connection With the other pole of the battery, and bowed spring-plates bearing with relation to the handle and operating to maintain it in either a normal upright position or in ahorizontal position in contact with said pin or post, whereby the handle operates to make or break the circuit and is held in positive position for both purposes, substantially as and for the purpose set forth.

2. An improved electric lamp, comprising a casing, a batteryarranged therein, a lamp in connection with one pole of said battery, a conductor extending from said connection to an exteriorly-arranged contact pin or post. a handle journaled upon the casing and in connection with the other pole of the battery, said handle having rectangular-faced gudgeons, and bowed spring-plates bearing with relation to said gudgeons, whereby the ban dle is positively maintained in either normal upright position or in horizontal position in contact with the pin or post and serves to either make or break the circuit, substantially as and for the purpose set forth.

- 3. An improved electric lamp, comprising a casing, a battery carried thereby, an exteriorly-arranged contact pin or post in connection with one pole of said battery, and a lamp comprised in the circuit, in combination with a journaled handle in connection with the other pole of the battery, and means for retaining said handle in either normal upright position or in horizontal position in contact with said pin or post, whereby the circuit is automatically maintained in either opened or closed condition by the fixed position of the handle, substantially as and for the purpose set forth.

4- An improved electric lamp, comprising a casing, a battery carried thereby, an exteriorly-arranged contact pin or post in connection with one pole of the battery, andalamp comprised inthe circuit, in combination with a journaled handle in connection with the other poleof the battery, said handle adapted to be brought into contactwith said pin or post, and spring devices for locking the handle in said contact position, whereby the handle serves as an automatic ci rcuit-maker, substantiall y as and for the purpose set forth.

5. An improved electric lamp, comprising a casing, a battery carried thereby, a lamp in connection with one of the poles of said battery, a bowed-sprin g contact-plate in connection with the other pole of the battery, and a handle in operative connection with the lamp and said spring contact-plate,whereby a positive circuit connection against jarring or jolting is provided, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 5th day of October, 1897.

DAVID MISELL.
