page_text: I WILLIAM SANDERSON of 1 Davison Street, Gateshead-on-Tyne in the County
of Durham, Moulder, do hereby declare the nature of this invention to be as
follows:-
It consists of improvements whereby the door knob is secured to a plain spindle
by means of a peculiarly shaped wedge or wedges in combination with a screw
collar.
The wedges are placed inside the hole in the knob and are so arranged that by
turning the screw collar which is on the outside of the necking of the knob, the
said knob is held firmly on the spindle by means of the wedges.
The wedges are turned up at each end, the turning on the inside end being in
the inward direction and is for the purpose of raising that ond to make it act as a
wedge the underside of this turning is preferably roughed or toothed in order that
it may form a better grip on the spindle; the turning on the outside is in the
outward direction and is for the purpose of overlapping the end of the knob, &
extends sufficiently to come into contact with the screw collar, so that it may act
as an abutment for the collar to screw against in adjusting the knob.
Thus the method of fixing is as follows. First the collar is screwed on to the
outside of the necking of the knob after which the wedges are placed inside the
hole in the knob, (the outer turned up ends preventing them from slipping in the
hole altogether) after which the knob is placed on the spindle & the screw collar
screwed up tightly against the bent up edges of the knob which causes the knob
to move outwards & so fix itself firmly against the wedges, & as the underside
of the wedge is raised by the inner bent up end the wedge has a kind of springy
nature which more securely holds the knob on the spindle.
Thus the wedge firmly grips the spindle by means of the face of the inside bent
up end which is caused by the outward pressure of the knob worked by the screw
collar butting against the outside bent up edge of the wedge.
The wedges are preferably made in pairs i.e. two are joined together or stamped
out of the same piece of metal one forming a right angle with the other.
They may however if desired be made singly.

I, WILLIAM SANDERSON of 1 Davison Street, Gateshead-on-Tyne, in the County
of Durham Moulder do hereby declare the nature of this invention for IMPROVE-
MENTS IN DOOR LOCK AND LATCH FURNITURE and in, what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and illustrated by the accompanying drawings:-
Fig. 1. is a longitudinal section showing the knob placed on the spindle but not
adjusted.
Fig. 2. is a longitudinal section shewing it adjusted.
Figs. 3. & 4. are transverse sections of the wedges looking towards the door.
. The invention consists of improvements whereby the door knob A is secured to
a plain or notched spindle B by means of a peculiarly shaped wedge or wedges C
in combination with a screw collar D.
The wedges C are placed inside the hole in the knob and are so arranged that
by turning the screw collar D which is on the outside of the neck of the knob, the
said knob is held firmly on to the spindle B by means of the wedges C as
follows:-
The wedges C are turned up at each end, the turning on the inside end c
being in the inward direction and is for the purpose of raising that end in order
to make it act as a wedge also to make it of a suitable shape to grip the spindle B
the underside of the grip at c¹ when a smooth spindle is used is preferably roughed
or toothed, in order that it may secure itself more firmly on the spindle B or
instead of this, the spindle B may be notched as indicated in figs. 1 & 2 and the
turned up end c¹ made in the shape of a tooth to fit into the notches on the
spindle B and so secure it. The turning on the outside c is in the outward
direction and overlaps the end of the knob A and extends sufficiently to come
into contact, with the screw collar D in order that it may act as an abutment for
the collar to screw against in adjusting the knob, the underside of this end at c
also forms a grip on the spindle B and where a notched spindle is used, it is made
in the shape of a tooth to fit into one of the notches on the spindle.
The method of adjustment is as follows-
First the collar D is screwed fully up on to the outside of the neck of the knob,
as shewn at d¹ fig. 1. next the wedges are placed inside the hole in the knob (the
outer turned up ends preventing them from slipping into the hole altogether) and
the spindle inserted which process causes the wedges to part or widen out until
they nearly fit the inside square hole of the knob as shewn at fig. 1, after which
the screw collar is adjusted causing the knob to move outwards and bind itself
against the wedges at e' as shown at fig. 2: thus causing the wedges to grip the
spindle at their two extremities c¹ and c. Thus the underside of the wedges at
their two extremities firmly grip the spindle, which is caused by the outward
pressure of the knob, worked by the screw collar abutting against the outside bent
up edge or flange of the wedge.
The wedges may be made thin so as to have a kind of springy nature to more
securely hold themselves on the spindle or they may be made thick & rigid. They

page_text: are preferably made in pairs, as indicated by figs. 3 & 4, but I do not bind myself
to these particular shapes, or they may be made singly if found preferable, also,
they may be cast, stamped, or manufactured by any suitable method.
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. A wedge or wedges placed inside the hole of the knob and made to grip the
spindle as substantially set forth.
2. A wedge or wedges having a flange or abutment as substantially set forth.
3. A wedge or wedges in combination with a screw collar working against the
flange or abutment, and causing the outward movement of the knob whereby it
secures itself against the wedges, as substantially set forth and for the purpose
specified.
4. A door knob secured by the parts arranged and combined as substantially set
forth, and for the purpose specified.
