I, EDWARD GRANT STAPLES, of 151, Edmond Street, Birmingham, in the
County of Warwick, Commission Agent, 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 :-
The object of this invention is to provide an adjustable bracket capable of sliding
freely on a rod, and yet self sustaining at any given position; such brackets being
suitable for general use.
My improved bracket is not only readily adjustable on a vertical rod but it is
easily attached and detached and its holding power adjusts itself in proportion to
the weight to be sustained.
One form of the improved bracket consists of an arm which has one end formed
to partly embrace the vertical rod and the other end extended to carry any required
weight.
A strut attached to the weight carrying limb of the arm of the bracket extends
downwards and has at its lower end a spring clip which partly embraces the vertical
rod.
A modified form of bracket has a solid half-bearing at the lower end of the strut
and a spring clip attached to the arm of the bracket at the end opposite to that on
which the weight is hung.
It is to be clearly understood that in all cases the self gripping action depends
upon the principle that the weight to be sustained causes a cross action which tends
to throw the upper and lower gripping parts of the bracket out of truth with the
rod and hence a binding action is brought into play.
The accompanying drawings shew practical constructions and applications of
these improved brackets; but it will be understood that the details may be varied
without departing from the nature of my invention.
Fig. 1 shews a side elevation of one form of a bracket constructed according to
my invention.

page_text: a is the arm carrying the upper bearing for the rod. 6 is the spring clip at the
lower end of the inclined strut oc, and d is the rod upon which the bracket is
adjustable, e is the bracket arm for carrying any article required; the said article
being hung upon the end e¹.
The action is as follows:-
The weight hung at el causes the bearing a to press upon the rod d and the clip b
to press upon the said rod in the opposite direction, so as to cause a binding action
or grip which prevent downward movement of the bracket, and thus the bracket is
made self sustaining in proportion to the weight hung at e¹.
Fig. 2. shews the modification where the arm a carries a spring clip f and at the
lower end of the inclined strut c is a solid half-bearing g partly embracing the
rod d.
As before, a weight hung at el will cause a binding action which will support
the bracket in any given position on the rod d.
By easing the pressure of the suspended weight the bracket may be moved up
or down on the rod d to any required position.
The rod d may be of any sectional form, but a round form gives the advantage
of turning the bracket laterally to any angle.
To detach the bracket from the vertical rod d the bottom clip or bearing is
pulled away from the said rod d, when the upper arm easily disengages itself; and
to refix the bracket the arm is engaged with the vertical rod d and the bottom clip
or bearing is brought into position.
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 :-
1. Adjustable self sustaining brackets having upper and lower bearings partly
embracing a vertical rod and holding by the binding action caused by a suspended
weight on the arm of the bracket; the said brackets being adjustable by easing the
pressure of the weight and attachable and detachable as described and illustrated
in Figure 1.
2. The modification of the bracket as described and illustrated in Figure 2.
Dated this 24th day of March 1896.
