CONSTANT FICQ, OF VICTORIA, BRITISH COLUMBIA, CANADA.,
ELECTRIC LAMP.
Specification of Letters Patent.
Patented Aug. 3, 1915.
Application filed February 14, 1914. Serial No. 818,739.
' which the following is a specification.
The invention relates to electric lamps of the incandescent type, the purpose being to prevent the loss of luminous rays'and to direct the same in a manner to obtain greater efliciency from a given amount of current.
In accordance with this invention the lamp comprises a base which presents an extended reflecting surface, such base receiving a globe and having the filament attached thereto andvextended' so as to present a maximum amount of light giving surface. The" invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.
In the drawings'hereto attached:-F1gure 1 is a view in elevation of an incandescent lamp embodying the invention. Fig. 2 is a I vertical central section. Fig. 3 is a view of the lamp inverted. i
Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the samereference characters.
The lamp comprises a base and a globe,
the latter: being transparent and the base being constructed of porcelain or other vitreous material of a nature so as not to transmit rays of light. The base comprises a stem 1 and a body 2, the latter belng eX-' tended and preferably of circular form. A groove 3 is formed in the outer portion of the body 2 near its edge and is intended to receive the edge of the globe 4 which is secured to such groove by means of cement. The side of thebody 2 facing the globe 4 constitutes a reflecting surface and serves to throw the rays of light in one direction,
thereby concentrating the luminous rays and preventing their waste in a direction opposite that required for use. The conductors 5 are preferably molded within the base and are connected respectively to the sleeve and button so as to make electric connection with the correspondin parts of the socket when the lamp is fitte to such socket in the manner well understood. The filament 6 is connected at its extremities to the conducthe lamp is adapted to withstand a shock without causing fracture of the filament. The reflectingsurfac'e of the base may be finlshed in anymanner. so'as to direct the rays of light to the besthdvantage for use.
From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily-ap- 'parent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it'under'stood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the invention as claimed.
Having thus described the invention, what is claimed as new is An incandescent electric lamp'comprising a base of vitreous material comprising a stem having formed integral at. one end thereof a relatively thin laterally extending annular flange having an annular groove near its periphery, the under surface of said flange constituting a reflector, a filament comprising a plurality of folds or loops arranged within the reflecting surface of the base, supports for the loops or folds of the an adhesive material interposed between the wall of said groove and the outer surface of the edge portion of said globe.
In testimony whereof I aflix my signature in presence of two witnesses.
CONSTANT FICQ.
