Specification of Letters Patent.
Patented Sept. 18, 1906.
Application filed May 20, 1905x fierial No. 261.408.
T to whom it may concern:
Be it known that I, JOHN -H. DALE, a citizen of the United States, residing at the city ofNew York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Electric Fixtures, of which the following is a full, clear, and exact description.
My invention relates to supports for brackets, and more particularly to improvements in the base-plate and means for securing the bracket thereto.
A well-known form of supporting means for the bracket of an electric light consists of a base-plate or tripod having a screw-threaded opening therein into which the threaded end of the bracket is secured. In practice it is found that in securing a bracket in the corner of a room the rotation of the bracket for the purpose of screwing it in place on the base-plate is prevented by said bracket com ing in contact with one of the walls of the room. It is also likewise frequently desirable to secure the bracket near an object proj ecting from the wall, in which event the rotation of the bracket is likewise prevented by said projecting object.
My invention consists of a base-plate so constructed that the threaded end of the bracket may be readily secured in place without rotation of said bracket.
In the drawings accompanying and forming a part of this specification, Figure 1 is a front elevation of the base-plate or tripod for sustaining the bracket in place, and Fig. 2 is a central vertical section of said base-plate and its inclosing canopy as secured in position on a wall, showing a bracket held in place by said base-plate or tripod.
The frame of the base-plate is designated by the numeral 1. Within this frame is an elongated opening 2, one wall 3 of which partially surrounds an opening 2*, which has screw-threads cut therein. The wall 3 forms .one of the jaws of a socket, hereinafter more bottom wall 6 of the opening 2, and said jaw is easily and readily adjusted by the rotation of the screw 5. Said screw 5 also serves to hold the jaw 4 in place.
The base-plate is. provided with legs having means for securing the base-plate to the wall in the well-known manner, illustrated in Fig. 2.
7 is an ordinary electric-light bracket screw-threaded at its inner end 8. To secure said bracket in place, the jaw is opened a sufficient distance to readily permit without rotation the introduction of the threaded end 8 of the'bracket in the circular opening, the threads on said bracket registering with the threads in the wall 3. The jaw 4 is then closed by setting forward the screw 5, thus securely locking the bracket in place.
The usual canopy 9 for covering and concealing the tripod may be used, as shown in Fig. 2.
The tripod or base-plate of my invention may be employed as a support for the identical form of bracket in use with the ordinary tripod When the bracket is to be located in such position that it becomes impossible or inconvenient to rotate said bracket to screw it into the tripod, the base-plate or tripod of my invention may be employed and the bracket readily secured thereto in the desired position.
Having described my invention, I claim 1. In a base-plate for a bracket, a frame having an elongated opening therein, one of the walls thereof having screw-threads cut therein, and a jaw adjustable longitudinally in said opening, the inner side of said jaw having screw-threads therein registering with the threads in said wall when the jaw is closed, said wall and jaw cooperating to form clampmg means.
2. A supporting base-plate comprising a socket having a screw-threaded opening, part of the threaded walls of which are movable, and means for expanding and contracting the movable part of said walls whereby a screwthreaded bracket may have its threads either screwed or clamped in mesh with those of the plate, substantially as and for the purpose set forth.
