COMPLETE SPECIFICATION.
A New or Improved Movable Bracket.
REUBEN JAMES BOTT E'ectrical Engineer 9 Park Place Villas St. Mary's
Paddington London do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to ball bearing, clips, or jointed brackets or pendants for
carrying sockets & lamps for electric light, or for other purposes.
And in order that my invention may be more fully understood, I have appended
hereunto one sheet of drawings, showing the application to two forms of brackets,
one arranged for the lamp socket to be fitted to the arm which will be made of small
diameter, the wires in this case are loose or external. The other arrangement
shows the bracket arranged for the lamp socket to be screwed on the end of the
arm of bracket, which will be made of tube, the wires in this case being internal
or inside the whole of the bracket.
Fig. 1 shows sectional elevation of bracket arranged for external wires.
Fig. 2 shows elevation of ditto.
Fig. 3 shows plan of ditto.
Fig. 4 shows sectional elevation of bracket arranged for external wires but with
the addition of a swivel pin joint at the back plate, and the clips are made of
1 piece of metal instead of 2 half pieces as in Fig. 1.
Fig. 5 shows elevation of ditto.
Fig. 6 shows sectional elevation of bracket arranged for the wire to pass through
the bracket to lamp & socket.
Fig. 7 shows plan of ditto.
Fig. 8 shows front elevation of ditto.
In carrying out my invention I make a ball A true and smooth, and as shown in
Fig. 1, this is fitted into the cup or hollow bearing forming part of the back plate B
on the top of the ball, a plate C also hollowed out to fit the ball, is fitted; and
through this top plate, a screw D passes into a tapped hole in the bottom or back
plate by this screw, the top plate can be tightened on to the ball at will, thus
giving the recessary fit or pressure to the ball, so that the arm E will hold up the
weight of the lamp, socket, &c. which will be fixed to it, and it will be seen that by
arranging the edges of the plates F a considerable movement in any direction can
be traversed by the arm.
In Fig. 4, it will be seen that instead of plates to grip the ball, I use a piece of
metal a stamped out of one piece to the desired shape, and that it fitted this to the

page_text: back plate by a rivet b which is tightened up so that I can obtain a complete turn
of the front portion of my bracket.
In Fig. 6 it will be seen that I arrange the bracket for bringing the wire a
through, or covered up, and in this case I use a ball b of larger diameter.
The back plate is altered slightly, by boring a hole c through it and leaving
sufficient metal on the top to obtain a thread for the bolt d as shown.
The top plate is secured by a small bolt as shown which can be adjusted to
give the necessary pressure on the ball. As shown by the dotted lines e I cut
away the back portion of the ball also a portion of the plates, for the purpose of
getting clearance for the wires.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In the construction & adoption of a ball & cup bearing or clips arranged and
fitted as a bracket giving a movement of the arm in any direction from its centre,
up, down, or sideways, and operating substantially as and for the purposes herein-
before described illustrated on the accompanying drawing.
Dated this 11th day of August 1891.
