and 'Handles to their Spindles.
I EMMA WEBB of 36 Highgate Road Birmingham General Dealer do hereby
declare the nature of my invention for ATTACHING AND ADJUSTING DOOR KNOBS
AND HANDLES TO THEIR SPINDLES, to be as follows:-
A half ball with a square hole through its centre and a square tube are both
fitted to travel along a spindle, screwed on its angles. The said half ball & tube
are connected by a key which works in a groove cut for it in one side of the
spindle. When the said half ball and square tube are connected there is a space
between them, in which a loose collar works, such loose collar having a circular
hole through its centre, tapped to work on the screwed spindle. When the square
tube is fitted and fixed into the knob, the loose collar being turned on the spindle
travels along it and forces forward the said half ball which being connected with
the key & square tube, draws the knob after it, the said knob being adjustible
thereby at any part of the spindle by the simple turning of the loose collar. The
said half ball works in a cup in the rose.

I EMMA WEBB formerly of 36 Highgate Road Birmingham but now of
"Overdale" Coventry Road Birmingham General Dealer do hereby declare the
nature of my invention for ATTACHING AND ADJUSTING DOOR KNOBS & HANDLES
TO THEIR SPINDLES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
A half ball with a square hole through its centre and a square tube are both
fitted to travel along a spindle, screwed on its angles. The said half ball and tube
are connected by a key which works in a groove cut for it in one side of the
spindle. When the said half ball and square tube are connected there is a space
between them in which a loose collar works, such loose collar having a circular
hole through its centre tapped to work on the screwed spindle. When the square
tube is fitted and fixed into the knob, the loose collar being turned on the spindle,
travels along it and forces forward the said half ball which being connected with
the key and square tube, draws the knob after it, the said knob being adjustable
thereby at any part of the spindle by the simple turning of the loose collar. The
Baid half ball works in a cup in the rose.
I occasionally dispense with the half ball in front of the loose collar and
substitute therefor a pommel on the front of the loose collar which said pommel
fits into a hole cut through the rose where it takes its bearing when the knob is
in work.
Another method of effecting the same object is to cast a cup collar or mount on
to the square tube, and when the said square tube is fitted into the knob, the edge
of the said cup collar is spun over the neck of the said knob, and thereby firmly
fixed to it. I then provide another cup collar, larger than the fixed cup collar
referred to, and having a circular tube cast on one side, the bore of which is
screwed to travel along the spindle, and I then spin the edge of the said larger cup
collar over the edge of the fixed cup collar, on which it works loosely so that when
it is turned and caused to travel along the spindle, it draws the knob after it the
one way, or pushes the knob in front of it the other, thus enabling an adjustment
of the knob & locking the same at any part of the said spindle.
When the said knob is adjusted on the spindle it is close to the rose which is
fastened to the door, and although locked on the spindle, the friction of the loose
collar against the said rose in the act of working the knob, has a tendency to
unscrew the said loose collar and cause the knob to travel back along the spindle
and consequently to have end play. To prevent this I cast radial grooves or slots
in the face of the fixed cup collar, and through the edge of the loose collar I bore a
hole into which a pin or cotter can be inserted, and the said pin entering either of
the said grooves or slots in the said fixed collar, causes the two collars to be
locked together.

It is found in practice that the square end of the screwed spindle, as the knob is
drawn along it by the loose collar, crosses the entrance to the square tube or socket
in the knob so that it will not enter. To prevent this I bevil the end of the said
spindle.
DESCRIPTION OF THE DRAWINGS.
Figures 1, 2, & 3 refer to the first part and figures 4, 5, 6 & 7 refer to the second
part of my said invention.
A is a cross section and A' a front view of the half ball with square hole
through its centre, and to which the key C is attached. B is a longitudinal
section and B' a front view of square tube or socket with cup collar or mount
attached and spun over neck of knob, the front of the said cup collar having radial
grooves or slots cast in. This square tube or socket is also connected with the
key C.
C is section of key connecting A & B and which travels along the
groove F in the spindle. D is a cross section and D¹ front view of loose collar,
tapped to work along the screwed spindle E. E is a longitudinal section of spindle
screwed on its angles, and E' is a cross section of the same, showing groove or key
way F cut into one side for the key C to travel along.
Ġ is longitudinal section and G₁ a side view of screwed spindle without groove
or key way cut into one side H is a cross section Hside view and H front of
loose collar spun over the edge of fixed collar J and screwed to travel along the
spindle G. Jis section of square tube or socket with cup collar fixed to neck of
knob, the front of said cup collar having radial grooves or slots cast in.
K is a section of the rose screwed to door M.
N&N are sectional and side views respectively of pin or cotter fixed through
edge of loose collar, and into the radial slots O for locking the fixed and loose
collars together.
P shows bevilled end of spindle.
The method of operation is as follows:
The spindle G (which has a fixed knob on the one end) being passed through
the lock, the free end projects beyond the face of the door. The rose K is then
pushed along the said spindle and screwed on to the door M by means of the
screws P P. The knob L' is then drawn along the spindle G by means of the
loose collar H which is turned until the face of the said loose collar touches
the rose K, when the pin N being inserted into one of the radial slots O through
the hole in the edge of the loose collar H, the knob is found to be perfectly
secured to the spindle.
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 :
1st The use of a half round bearing attached to a knob by a key or other con-
nection, and fitting into a cup of corresponding section in a rose.
2nd The use of a key working in a groove cut into one side of a spindle of
square or other section, and to which a knob can be attached and either dawn
forward or pushed backward along said spin le, substantially and for the pur-
poses herein before described.
3rd The use of a loose collar tapped to travel along a screwed spindle and spun
over and working round or in front of the mount of a knob or otherwise, such

page_text: mount having radial grooves on its face, or a hole or holes through its edge,
corresponding with a hole or holes in the said loose collar, into which a pin can be
inserted for the purposes of adjusting and locking the said knob on to any part of
the said spindles substantially as herein before described.
4th The bevilling of the end of a screwed spindle of square section in order that 5
it may the more easily enter a square socket.
