AN ELECTRIC LAMP COVER AND SWITCH. closing and protecting an electric lamp is so construct ed that the lamp will always be extinguished when the covers are closed upon it. The improvement has been patented by Mr. Emil T. Mueller La Crosse Wis. The socket receiving the lamp base has its opposite end closed by a vulcanite cap through an aperture in which extends the flexible conductor. In ears at each side of the socket are pivoted arms carrying the lamp covers there being a short stud at the outer end of each cover whereby the covers will be locked when closed on the lamp. An elastic rubber or other spring connects the covers with the sides of the socket and tends to hold them in an elevated position as shown in the sectional view. One of the cover-supporting arms is provided with an insulating bushing and washer and is prolonged in curved form within the socket having at its inner end a contact spring adapted to form an electrical contact with a button on the base of the lamp. A bracket of insulating material on the inner wall of the lamp socket carries a metallic arm to which is attached one strand of the conductor a screw in the arm connecting with a metallic spring whose other end is connected with the projecting inner end of the cover-supporting arm while the other strand of the conductor is connected with a screw in the wall of the socket. When the covers are closed the contact spring is held away from the button as shown in dotted lines in the sectional view and the circuit is broken ; but when the covers are in open position as shown in the full lines the current flows from one strand of the con ductor through the lamp filament to the socket and thence to the other strand of the conductor. For further information relative to this improve ment address Mr. Charles B. Miller No. 329 Main Street La Crosse Wis. A PORTABLE HOT WATER OR STEAM HEATER. The portable heater patented by Mr. A. White is designed for use with gas oil or gasoline as fuel without waste or sm
