Improvements in Securing Door Handles.
I, ALEXANDER CÆSAR FRANKLIN of May Cottage Shoreham Sussex Engineer
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the better securing of door handles & knobs &
consists in so arranging a set screw & locking device that when once the set screw
is screwed down into its place and secured by the locking piece or guard it shall
be prevented from turning & becoming unscrewed.
Having now described the nature of my invention I will proceed to give one
way of carrying the same into effect. To an ordinary door handle placed on an
ordinary spindle I arrange a set screw in the usual manner & position but con-
structed rather longer than ordinarily & having a deeper slot or groove for turning
than usual, and I so arrange the length of the screw that when down in its place
the upper part having the slot for turning shall stand well outside the handle &
the slot shall be at right angles to the axis of the handle, and in order that this
may be attained without unduly straining the thread of the screw I sometimes
arrange a horizontal slot or a hole as near as convenient to the lower end of the
set screw so that by its spring it will allow of turning the screw until the slot is in
the required position. I now arrange a ring or segment of a ring of wire or other
suitable material flattened if necessary in the middle to fit into the slot in the head
of the screw & this is sprung over the part of the door handle where the set screw
is usually placed & the flattened part drops into the slot in the set screw & thereby
completely locks it. I sometimes arrange to make the screw with a square or oblong
head & make a hole of corresponding shape in the locking ring which would then
be preferably of flat section instead of round as in the case of a wire ring. I also
sometimes form a groove or recess in the neck of the handle so that the ring may
lie therein & that the head of the screw may not project beyond the neck of the
handle.

in the usual manner & position but constructed rather longer than ordinarily and

arrange to make the screw with a square or oblong head & make a suitable hole in
the locking ring or segment which would then preferably be of flat instead of
round section as in the case of a wire one. This form applies better to larger
handles. I also sometimes form a groove or recess in the neck of the handle so
that the metallic ring may rest therein & that the ring and head of the screw may
not project beyond the neck of the handle.
DESCRIPTION OF DRAWINGS.
Fig. 1 represents a door handle marked A fitted on a spindle B in the ordinary
way and having a groove C crossing the centre line of the hole for the set screw D.
E is a spring of suitable material fitting into the groove C. and arranged if
required with a flat part to fit into the slot in the top of the set screw D. & so
tempered that it can be sprung into its place when the set screw D has been fixed
to secure the handle A on the spindle B.
Fig. 2 represents a cross section of the handle A at the groove C.
Fig. 3 shews an enlarged view of the ring E and Fig. 4 shows a plan of the same
indicating the part flattened to fit into the set screw.
Fig. 5 represents a flat ring with an angular hole therein to fit over the head of
a suitably formed set screw as before described.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is.
1. The use of a band or ring sprung round the neck of a door or other handle
for the purpose of preventing the set screw turning therein & thus becoming
unscrewed this being effected not by means of pressure on the head of the screw
but by the ring or band either passing through the slot in the head of the set
screw or around a suitably formed head on the set screw.
2. The combination of the use of a band or ring together with a suitable groove
or recess in the neck of the handle for the purpose of locking the set screw &
preventing its turning substantially as herein described.
