UNITED STATES -ALVABO MULLOR, OF IBEZIERS, FRANCE.
ELECTRIC LAMP WITH SEVERAL FILAMENTS.
Application filed July 8, 1824, Serial 1T0. 724,896, and in France May 16, 1924.
porting the filaments soldering has to be per-' formed on the top of the lamp.
This invention allows for such soldering being dispensed with whence a much more rapid fitting up is obtained while being able to light up either one, two or more filaments in the same lamp and to thus produ'e a more or less lummous intensity, electric energy being merely used for the filaments in circuit, so that when one filament is ena second filament enters into act-ion and so on until the last filament is reached, the duration of the lamp being thus increased two or three times.
A lamp thus used can be utilized anew by the manufacturer who might be willing to take it over.
The object of this invention is to obtain a lamp with several filaments and solderless contacts connected to a socket the contact wires of which are suitably arranged and lead to a circuit breaker having several directions allowing for the required lighting up combinations.
The accompanying drawings show by way of example a mode of carrying the invention into practice as applied to a lamp having three filaments.
Fig. 1 is an elevation of the lamp.
Fig. 2 is an axial section of the bottom part thereof.
Fig. 3 is an axial section of the socket.
Fig. 4 shows the upper part of the lamp.
Fig. 5 is a modification in the lamp fitting.
The filaments 1 of the lamp extend freely within the bulb 2 connected to. the lamp bottom of insulating material. The filament end are connected to the contacts 4 by side screws-5 arranged in recesses formed in the lamp bottom, and which may be easily handled from the outside. These screws lead to cavities 6 suitabl arranged in the lamp bottom 3 and forming a contact with the metallic jackets situated in these cavities. For a three aments lamp there are four such cavities preferably provided at the top of a square of the upper lamp hoop. A ring 8 carrying the points 9 needed for the bayonet joint serves to protect, alter fitting up, the screws 5 from all outside contact.
Upon the lamp bottom 3 is arranged a plug 11 of insulating material carrying a number of slit pins 12 equal to that of the cavities 6 wherein the said pins enter and hold the lamp by their springy action. Wires lead to these pins on their way from a circuit breaker 14 connected to the line and fitted in any well known manner.
In the modifiz'ation shown in Fig. 5 the lamp is directly mounted on the two line wires, but the necessity of having four wires; but the necessity of having four wires for a three filaments lamp requires the use of a pear shaped bulb 13 fitted and operating in any well known manner.
It must be well understood that the number of lamp filaments may vary, the arrangement of the cavities 6 and of the split pins 12 varying according The cavities 6 may likewise assume the form of massive contact pieces and the socket may be of ordinary construction but provided with four pistons instead of two without departing from the nature ofthis invention.
I claim:
An electric lamp having the bottom thereof formed with contact recesses", metallic sleeves arranged in said recesses, screws leading into the bottom and terminally enga 'ng each of the sleeves, a series of independent filaments for the lamp, the terminals of the filaments being connected to the respective screws, and a jacket carried by the bottom and overlying and spaced from the screws to protect the latter from external contact.
Signed at Paris, June A. D. 1924.
ALVARO MULLOR.
France, this 25th day of to each particular case.
