PROVISIONAL SPECIFICATION.
.Improved Means for Securing Door Knobs on their Spindles.
I, EDWARD 'COLLIER, of Woodfield, Water (Orton, Warwickshire, Wood
Turner, do hereby declare the nature of this invention to be as follows:-
This invention consists of the hereindescribed improved means for securing door
knobs on their spindles the object of my invention being to effectually secure the,
knob on the spindle by a simple construction and arrangement of parts herein
described. For the purposes of my 'invention the knob spindle is of the usual
square section screw threaded round the corners. In addition to being screw
threaded on the corners the spindle is drilled through from side to side with a
number of small holes arranged in a row as close as possible together. The rose
which is fixed to the door as usual is provided with a Hanged or other bush which
is screw threaded so as to screw on to the spindle. The door knob is also made
with a metal bush screw threaded.so as to screw on to the spindle this 'bush being
by preference made with a flange which fits against the foot of the knob. In the
usual recess in the front of the rose and between the foot of the knob and the front
of 'the rose I provide a dished spring metal plate or washer or two or more of the
said plates or washers or an indiarubber or other elastic washer or spring which is
or are compressed between the foot of the 'knob and the rose when the 'knob 'is
fixed on the spindle.
When securing the knob on the spindle the latter is first passed through the hole
in the door and the rose is screwed along the spindle against the door and fixed to
the latter by screws as usual. The spring metal plate or washer or the two or
more said plates or washers or the indiarubber or other elastic washer or spring is
or are then threaded on to the spindle and placed in the recess in the front of the
rose. The knob is now threaded on to the spindle and screwed down so as to
slightly compress the spring washer in the recess in the rose and the knob is burneȧ
until a cross hole in the neck of the knob comes opposite one of the drilled through
holes in the spindle. A split cotter peg or screw is then passed through the neck
of the knob and through the bush therein and through one of the through 'holes in
the spindle and clenched over if desired on the other side of the knob thus
effectually securing the knob on 'the spindle. It will be seen that the spring washer
or other spring or elastic part which I provide in the recess in the front of the rose
effectually prevents any shaking of the knob and allows of the 'knob being adjusted
on the spindle to the proper position to enable the cotter peg or screw to be passed
through the hole in the neck of the knob and through one of the holes in the
spindle.as stated above.
The arrangement above described is suitable for door knobs and roses of wood
or china but when the knob and rose are made of metal the 'knob and rose do not
require to have separate bushes but they are themselves directly screw threaded 'to
suit the spindle.

I, EDWARD COLLIER, of Woodfield, Water Orton, Warwickshire, Wood
Turner, 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 consists of the hereindescribed improved means for securing door
knobs on their spindles the object of my invention being to effectually secure the
knob on the spindle by a simple construction and arrangement of parts which I will
describe by referring to the accompanying drawings.
Fig: 1 represents a pair of door knobs one of which (shewn in section) is fixed to
its spindle in accordance with this invention;
Fig. 2 is a separate view of a part of the said spindle;
Fig. 3 shews separately a spring plate or washer which is placed between the
foot of the knob and the rose as hereinafter described and
Fig. 4 shews a rose with a slightly different form of bush.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
For the purposes of my invention the knob spindle A is of the usual square
section screw threaded round the corners but in addition to being screwed round
the corners the spindle A is drilled through from side to side with a number of
holes arranged in a row along each side as close as possible together. The
rose C, which is fixed to the door D as usual, is provided with a flanged or other
bush E which may be of the ordinary kind made either with an outside flange el as
shewn in Fig. 1, or with an inside flange e2 as shewn in Fig. 4, or without a flange
the said bush being screw threaded inwardly at e³ so as to screw on to the spindle A.
The door knob F is also made with an ordinary metal bush G fixed to the knob in
the usual way and screw threaded inside so as to screw on to the spindle A this
bush being by preference made with a flange g¹ which fits against the foot of the
knob F. In the usual recess c¹ in the front of the rose C, between the flange g¹ at
the foot of the knob and the front of the rose C, I provide a dished spring plate or
washer such for instance as H, or two or more of the said spring plates or washers,
or an indiarubber or other elastic washer or spring, which is or are compressed
between the mount G at the foot of the knob and the rose C when the knob is
fixed on the spindle.
When securing the knob F to the spindle A (to the other end of which the knob I
is permanently fixed in any ordinary manner) the spindle A is first passed through
the hole in the door and the bush of the rose C is screwed along the spindle A up
to the face of the door the rose being then fixed to the latter by screws as is usual.
The spring plate or washer H, or two or more of the spring plates or washers, or
the indiarubber or other elastic washer or spring is or are passed on to the spindle A
and placed in recess c in the front of the rose C. The knob F is now threaded on
to the spindle A. and screwed down so as to slightly compress the spring washer H
or other spring in the recess in the rose and the knob F is turned until the cross
hole in the neck of the knob F comes opposite one of the drilled through holes b
in the spindle A. A split cotter or a peg or screw is then passed through the
neck of the knob F and through the bush G thereof and through one of the
through holes in the spindle A, and clenched over if desired on the other side of
the knob, thus effectually securing the knob F on to the spindle A. Instead of the
spindle A having the holes as stated above, the said spindle may be grooved along
one or more sides in the usual way for the screw in the foot of the knob to engage
with.

page_text: It will be seen that the spring washer H or other spring or elastic part which I
provide in the recess e in the front of the rose C, effectually prevents any shaking
of the knob and allows of the knob F being adjusted on the spindle A to the proper
position to enable the cotter ; or peg or screw to be passed through the hole in the
neck of the knob and through one of the holes 6 in the spindle A as stated above.
By the cotter or peg pin or screw passing right through the bush of the door knob
and through the spindle as stated above the pulling strain on the knob is taken off
the screw threads in the knob and spindle, and the screw threads in the former are
not liable to be stripped by the screwed corners of the spindle when there is an
extra pulling strain on the knob.
The arrangement above described is suitable for door knobs and roses of wood or
china but when the knob and rose are made of metal the rose aud knob do not or
may not require to have separate bushes but are or may be themselves directly
screw threaded to suit the spindle A as will readily be understood.
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. The combination with a square section door knob spindle which is screw
threaded at its corners, of a knob and rose bush both screwed on said spindle,
means for preventing the knob from turning on said spindle, and one or more spring
plates or spring washers or the like contained in a recess in the front of the rose
and compressed between the foot of the knob and the bush or rose to prevent the
knob from shaking, all substantially as set forth.
2. The combination with a square section door knob spindle which is screw
threaded at its corners and made with a series of through holes arranged in rows, of
a knob and rose bush both screwed on said spindle said rose being made with a
front recess in which is or are one or more spring plates or spring washers or the
like compressed between the foot of the knob and the rose to prevent the knob
from shaking, and a screw pin, peg, cotter or the like passing through the neck of
the knob and through the spindle to fix the knob thereon, all substantially as set
forth.
3. The combination with the door knob of a square spindle screw threaded at its
corners and made with a series of drilled through holes for the screw, pin, peg,
cotter or the like in the foot of the knob to engage with, as set forth.
