IMPROVEMENTS IN ATTACHING DOOR-KNOBS TO THE SPINDLES
Year: 1884

page_text: JOSEPH WALKER Diesinker 13 & 14 Augusta Street Birmingham County of
Warwickshire do hereby declare the nature of my invention for IMPROVEMENTS
IN ATTACHING DOOR-KNOBS TO THE SPINDLES to be as follows:-
My invention consists of an improved method of attaching or fastening door
knobs to the spindles.
I will describe my improved process; I take an ordinary square door spindle
and make several round holes of uniform size through or nearly through the
spindle, I then make a pin or cotter that will fit either of the said holes in the
spindle and long enough to reach to the bottom of either of the said holes, the pin
or cotter having a good sized head, the said head preventing the pin or cotter from
passing through either of the holes it may be placed in, and also to secure the knob
to the spindle in the manner I will describe hereafter; I then take an ordinary
door knob having a square hole in neck of same, the square hole being of a.
suitable size to fit the square spindle and to allow of the knob passing on and off
the spindle as required; at the end of the said neck I leave a round projecting
flange:
I then take a knob rose with a round hole in centre through which the square
spindle can pass and having a projecting round rim in the front and centre of the
same, the rim being large enough to receive the flange on the neck of the knob
before described; having inserted the flange on the neck of the knob into the
projecting round rim on the front of the said rose, I turn over the edge of the said
rim on to the said flange, thus securing the knob and neck of the same to the rose,
leaving the rose sufficiently loose to allow of it turning round on the neck of the
knob by means of the flange on the front of the rose, I leave on (or secure to) the
back of the rose a round plate of metal, leaving a space between the front of
the rose and the said back plate as wide as the head of the pin or cotter before
described; in the centre of the said back plate of the rose, I make a round hole.
large enough for the spindle to pass through and turn round in the same, I then
make a slot in one side of the round hole in the said back plate of the rose, large
enough to allow the head of the aforesaid pin or cotter to pass into the space
between the rose and backplate of the same.

page_text: Having thus prepared the several parts I have just described, I take first the
square spindle and having secured a knob to what is called the fast end, I pass the
other end having the said round holes in it through the door, I then put the pin or
cotter into one of the said holes at the required distance from the door; I then
pass the end of the spindle through the round hole in the back plate of the rose,
then through the rose and into the square hole in the neck of the knob, I then
push the knob and rose over the spindle until the head of the pin or cotter enters
the space between the rose and back-plate of the same. The rose being made to
revolve on the neck of the knob as before described; I turn the rose round until
the slot in the back plate (through which the head of the pin or cotter passed into
the space between the rose and the back plate) comes to the opposito position to
the head of the pin or cotter, thus securing the head of the pin or cotter within the
space between the back and front of the rose, by this means the spindle fixed in
the neck of the knob. In the outer edge of the rose I make one or two holes
through which to nail or screw it to the door to prevent it turning round on the
neck and releasing the cotter from the chamber of the rose.
The advantages of my invention are great simplicity and strength and low cost
in production.
I claim the fixing of door knobs to the spindles by means of a hollow rose, i.e: a
rose having a circular space between the front and back parts, and the back part
having a slot in the centre round hole of a suitable size and shape to allow the
projecting head of a pin or cotter after being placed in a. hole in the spindle
to pass through the slot into the said space or chamber of the rose,
the rose
being attached to the neck of the knob, so that it may be moved round and thus
bring the head of the pin or cotter into such a position in the chamber of the rose,
as to securely fasten the knob to the spindle.

I JOSEPH WALKER of 13 & 14 Augusta Street Birmingham in the County of
Warwick Brassfounder do hereby declare the nature of my invention for IMPROVE-
MENTS IN ATTACHING DOOR KNOBS TO THE SPINDLES 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 section of the door knob with the spindle attached.
Fig. 2 an elevation of the slotted underplate.
I take an ordinary square door spindle A and make several round holes B of
uniform size through or nearly through the spindle.
I then make a pin or cotter C that will fit either of the said holes in the spindle
of sufficient length to reach to the bottom of either of the said holes the pin or
cotter having a good sized head which prevents it from passing through either
of the holes that it may be placed in & also securing the knob to the spindle
in the manner as hereinafter described. I. then take an ordinary door knob D
having a square hole in the neck of the same the square hole being of a suitable
size to fit the square spindle and to allow of the knob passing on & off the spindle
as required. At the end of the said neck I leave a projecting flange E as in the
ordinary knob for the purpose of securing it to the rose plate.
I then take a knob rose F with a round hole in the centre through which the
square spindle A can pass having a projecting round rim in the front and centre of
the same as shewn by dotted lines G the rim being large enough to receive the
flange on the neck of the knob before described; having inserted the flange on
the neck of the knob into the projecting round rim on the front of the said rose,
I turn over the edge of the said rim on to the said flange as shown by the strong
lines on the drawing thus securing the knob & neck of the same to the rose, leaving
the rose sufficiently loose to allow of it turning round on the neck of the knob.
I now make an inside plate H having a round hole in it sufficiently large for the
square spindle to pass which is kept in position by the underplate & is for the
purpose of steadying the rose plate & making it fit better on the neck of the handle
it also serves for the cotter to work against & so keeps it in position.
I leave on or secure to the back of the rose a round plate of metal I leaving
a space between the front of the rose or the inside plate & the said back plate
as wide as the head of the pin or cotter before described; in the centre of the
said back plate of the rose, I make a round hole large enough for the spindle to
pass through and turn round in, I then make a slot L in one side of the round hole
in the back plate large enough to allow the head of the aforesaid pin or cotter to
pass into the space between the rose or inside plate and the back plate.
Having thus prepared the several parts I have just described I take first the
square spindle A and having secured a knob J to what is called the fast end I pass
the other end having the round holes B in it through the door K I then put the.
pin or cotter C into one of the said holes B at the required distance from the door,
I then pass the end of the spindle through the round holes in the back & inside
plates I & H of the rose, then through the rose F and into the square hole in the

page_text: neck of the knob I then push the knob & rose over the spindle placing the head
of the pin or cotter opposite the slot through which it passes into the space between
the inside plate & back plate of the rose. The rose being made to revolve on the
neck of the knob as before described; I turn the rose round until the slot in the
back plate reaches the opposite position to the head of the pin or cotter thus
securing the head of the pin, or cotter within the space between the back & front
of the rose by this means the spindle is securely fixed in the neck of the knob.
In the outer edge of the rose I insert one or two screws or nails to retain the rose
& underplate in position.
In releasing it the pin or screws are taken out and the rose turned until the slot
hole comes opposite the head of the pin when the knob may be pulled from off the
spindle. The advantages are simplicity.& durability combined with low cost of
production.
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 fixing of door knobs to the spindle by means of a hollow or chambered
rose: i.e. a rose having a circular space or chamber between the front & back
parts and the back part having a slot in the centre, round hole of a suitable size
and shape to allow the projecting head of a pin or cotter after being placed in a
hole in the spindle to pass through into the said chamber of the rose; the rose
being attached to the neck of the knob, so that it may be moved round & thús
bring the head of. the pin or cotter into such a position in the chamber of the rose,
as to securely fasten the knob to the spindle as herein before specified and illustrated
by the accompanying drawings.
