CHARLES A. PBOCTOR, 01' LOS ANGELES, CALIFORNIA.
INGANDESCENT ELECTRIC LAMP.
Applicatiom filed July 30, 1924. Serial No. 729,172.
Among the principal objects which the present invention has in view are: To increase the lighting efficiency of the filament used in said lamp; to increase the length of 5 useful life of the filament; to increase the,
illumination of the lamp; and to reduce the cost of manufacture and installation in proportion to the efi'ected illumination.
Drawings.
The figure shows a side view of an electric lamp constructed and arranged in accordance with the present invention.
Description.
Referring to the drawing, the numeral 5 is employed to indicate a support for the double coil 6. The support 5 is passed through the end loop 7 of the double coil before being mounted in the neck 8 of the shank 9 of the lamp. The shank 9 is constructed in the usual manner having a metal shell 10 and aporcelain cemented core 11 through which extend the terminals 12 and 13 of the support 5 and coil 6, respectively.
The terminals 12 are metallically connected with the shell 10, while the terminals 13 are metallically connected with the button 14 at the end of the shank 9.
From the foregoing, it will be seen the circuit terminals of the lamp are the button 14: and shell 10, and that the circuit is passed .t-herethrough to the coil 6 and support 5 when flowing. Both terminals 13 independently but equally convey current in the same direction through the respective convolutions of the coil 6, the current thus conveyed being globed at the loop 15 of the support 5 to be conveyed therefrom by the said support 5 to the shell 10, and thus out to the line of electric circuit to which it belongs.
The coil 6 is made of any suitable material for making filament to burn in partial varuum of the globe of an incandescent electric lamp. \Vhen making the double coil 6 the filament is first bent at the lengthwise center thereof and drawn to a parallel spaced relation, the spacing being relatively close, but in no event sufficiently close to contact. The doubled parallel filamentis then wound upon a mandrel, or other suitable device to form a helix of suitable length, the terminals 13 being maintained in their original parallel relation to be subsequently encased in the cement forming the core of the shank 9 of the lamp.
With a filament constructed and arranged as herein disclosed. each loop of the double helix becomes equally incandescent when current is supplied thereto through the terminals 13. The direct result of this arrangement is that there is formed an in candescent cylindrical column within the trans arent globe 16, from the outer surface of w ich is emitted the light rays for illumination. In the present case, the double result is disproportionately increased due to the fact that light emanations from each of the filament wires projected in any direction other than away from the said cylinder, is in turn met by emanations from the adjacent wire or from the wires forming the opposite side of the loops referred to. A reaction is thereby set up within the center of the helix due to the clash or impact of opposing emanations with the result that they are more violently returned and de; livered outward from the illuminated column formed by the filament.
While the present invention has been shown in the mechanical adaptation thereof to the socket lam as it is called, it will beunderstod that t e coilmay be employed in any known form of lamp and that the support may be charged or altered to suit the construction to which the coil is being adapted.
