PROVISIONAL SPECIFICATION.
Improvements in and connected with Suspension Brackets for
Hanging Lamps.
I, WILLIAM JAMES ROCHE, of Kildorrery, Co. Cork, Ireland, Gentleman, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with suspension
brackets for hanging lamps and in accordance therewith I provide a metal frame-
work, having a hinged door or flap through which the lamp is inserted, for the
suspension of the lamp. A horizontal bar or plate crosses the top of the frame-
work which bar or plate is extended beyond the diameter of the framing so as to
form ears or lugs which are suitably pierced or bored for the insertion of screws for
attaching to the ceiling, beam, or other overhead carrier. And in carrying my
invention into practice I form or construct the attaching or affixing screws in the
following manner :-
Said screws are made of a conical shape hollow from the base to a convenient
distance from the apex--the points being solid. A screw-thread is formed upon
the outer circumference which is caused to enter the wood work to which the
bracket is to be attached by turning a handle provided for the purpose which passes
through from the base of the screw upwards and which is attached to a spear
shaped head the branches of which head are pivotted to the end of the handle bar
or rod and at their free ends enter apertures formed in the sides of the hollow part
of the screw, aforesaid. By turning the handle, the spears or shafts of the head
of the handle-bar catching into the sides of the screw, the screw is worked into
its bed and when in position a sharp pull upon the handle brings the spears or
shafts downwards, causes them to project or protrude through the sides of the
screw and firmly embed themselves in the woodwork so as to securely hold the
lamp bracket in position.
The hollow screw aforesaid may be conveniently formed with a solid or hollow
base or head which takes against the horizontal bar or plate at top of framework
and holds all up securely.
To remove the lamp bracket when required the handle-bar is pushed upwards,
thus withdrawing the catches of the spear head from their engagement with the
woodwork of beam or other carrier, and then by turning the handle the screws may
be withdrawn and the whole released.

I, WILLIAM JAMES ROCHE, of Kildorrery, Co. Cork, Ireland, Gentleman, 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:
This invention relates to improvements in, and connected with, suspension
brackets for hanging lamps, and in order that the same may be fully under-
stood I will describe same with. reference to the accompanying drawings, and
letters and figures of reference marked thereon.
Fig. 1 is an elevational view of a suspension bracket with the affixing or
attaching screws shewn in section.
Fig. 2 shews one of the screws in plain elevation, and
Fig. 3 is a section of the screw in which the spears or shafts of the head of the
turning handle are shewn protruding so as to affix themselves in the supporting
beam or woodwork, these two latter figures being upon an enlarged scale.
Similar letters of reference indicate like parts in each of the figures...
In accordance with this invention I provide a metal framework a having a
hinged door or flap through which the lamp is inserted, for the suspension of the
lamp. The framework a may be of bars or tubes, suitably glazed, and of any
required shape. A horizontal bar or plate c crosses the top of the framework,
which bar or plate is extended beyond the diameter of the framing so as to form
ears or lugs d which are suitably pierced or bored for the insertion of the screws e
for attachment to the ceiling, beam, or other overhead carrier, and in carrying my
invention into effect. I form or construct the attaching or affixing screws e in. the
following manner:-
Said screws e are made of a conical shape hollow from the base to a convenient dis-
tance from the apex--the points as at f being left solid. A screw thread is formed upon
the outer circumference which is caused to enter the woodwork to which the bracket
is to be attached by turning a handle g provided for the purpose which passes
through from the base of the screw e upwards and which is attached to a spear
shaped head the spears or branches of which are pivotted to the end of the
handle bar or rod g, and at their free ends enter apertures i formed in the sides of
the hollow part of the screw e aforesaid. By turning the handle, the spears or
shafts of the head of the handle bar catching into the sides of the screw, the
screw e is worked into its bed and when in position a sharp pull up on the handle
brings the spears or shafts downwards and causes them to project or protrude
through apertures i in the sides of the screw e (see Fig. 3) and firmly embed them-
selves in the woodwork so as to securely hold the lamp bracket in position.
is
The screw e aforesaid may be conveniently formed with either a hollow (as
shewn) or solid head having a shoulder or collar el around same to take against
the horizontal bar or plate at top of the framework a (see particularly Fig. 1 of
the drawings). To remove the lamp bracket when required the handle bar 9
pushed upwards, thus withdrawing the catches or spears from their engagement
with the woodwork of beam or other carrier, and then by turning the handle the
screws may be withdrawn and the whole released.
The solid portions of the screw e I preferably so shape that the triangular or
spear-shaped clasp fits into it. This makes the screw strong and capable of with-
standing the strong pressure applied when being twisted or turned by the handle
bar.

page_text: The spears or catches are pointed at their free ends so as to easily enter the
timber or ceiling immediately the handle bar is pulled downwards. In a suitable
position in the hollow screw e I form a stop k to prevent the spears or catches being
pulled down lower than the horizontal position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improvements in and connected with, suspension brackets for hanging
lamps substantially as herein before described and shewn.
2. In suspension brackets for hanging lamps the affixing or attaching screws e
with their turning handles g and spears or catches h constructed and operating
substantially as and for the purposes herein before described and shewn.
3. In suspension brackets for hanging lamps the metal framework a having a
hinged door or flap and cross top bare formed with lugs or ears e¹ in combination
with the screws e and turning handles 9 carrying the spears or catches / all sub-
stantially as for the purposes hereinbefore described and shewn.
Dated this 3rd day of November 1897.
