We SAMUEL BOTT, of No. 1 Bloomsbury Street, Birmingham, and CHARLES HOMER,
of No. 88 Vauxhall Road, Birmingham, both in the county of Warwick, and both
Manufacturers, do hereby declare the nature of this invention to be as follows:-
--
This invention relates to the manufacture of knobs or handles for doors or other
purposes, and in the forming of the spindles (or their equivalents) whereon such knobs
or handles are secured, and has for its object a method of securing the said knobs
or handles upon such spindles by means of a split neck being clamped or gripped
thereon.
The spindle may be prepared in several ways to suit this our method of fastening,
but generally we should make a slot or opening up the centre of the spindle, extending
from the end along to about the same distance that is ordinarily used for adjustment
purposes. The knob upon one end, (when two knobs are used) may be fixed upon the
spindle if desired, or, otherwise this our invention may be applied at both ends.
"
We then take a knob similar to those in ordinary use, having a square or other
shaped angular hole to suit the shape of the spindle. Across this hole, and, length-
wise with the spindle, we cut a slit, or saw cut" up the neck for some distance. At
right angles to this slit we pass a serew pin through the said neek, passing across the
hole, and having a plain hole for such screw pin in one side of the neck, but tapped
upon the other side of the said neck, so that when screwed up it shall draw the two
be understood:-
parts of the neck divided by the slit, together. Thus the action may
when the knob is passed up the spindle, the middle part of the pin passes along the
slot or opening in the said spindle; when by screwing the pin up, the two parts of

page_text: the neck of the knob are brought closer together, thus firmly gripping the spindle in
any desired position.
The slot in the spindle may be either formed across the spindle (transversely) from
side to side, or diagonally from corner to corner. Or in some cases we may only
form the slit upon one side of the neck, and not right across.
Or instead of forming the slot or opening in the centre of the spindle we may pas
the screw pin across the side of the spindle.
This screw pin may be made a plain pin with a head at one end and screwed at the
other, but generally we should prefer to enlarge its diameter at each end. This our
invention may be applied to china, wood, metal or other furniture by suitably forming
their necks of metal.

We SAMUEL BOTT, of No. 4 Bloomsbury Street, Birmingham, and CHARLES HOMER,
of No. 88 Vauxhall Road, Birmingham both in the county of Warwick and both
Manufacturers 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 relates to the manufacture of knobs or handles for doors or other
purposes, and in the forming of the spindles (or their equivalents) whereon such
or handles are secured, and has for its object a method of securing the said
knobs or handles upon such spindles, by means of a split neck being clamped or

The spindle may be prepared in several ways to suit this our method of fastening,
but generally we should make a slot or opening up the centre of the spindle,
extending from the end along to about the same distance that is ordinarily used for
adjustment purposes. The knob upon the one end (when two knobs are used,) may
be fixed upon the spindle if desired, or, otherwise this our invention may be applied
at both ends.

We then take a knob similar to those in ordinary use, having a square or other
shaped angular hole to suit the shape of the spindle. Across this hole, and length-
wise with the spindle, we cut a slit, or "saw cut up the neck for some distance. At
right angles to this slit we pass a screw pin through the said neck, passing across the
hole, and having a plain hole for such screw pin, in one side of the neck, but tapped
upon the other side of the said neck, so that when screwed up it shall draw the two
parts of the neck, divided by the slit, together. Thus the action may be understood:-
when the knob is passed up the spindle, the middle part of the pin passes along the
slot or opening in the said spindle; when by screwing the pin up, fhe two parts of
the neck of the knob are brought closer together, thus firmly gripping the spindle in
any desired position.
The slot in the spindle may be either formed across the spindle (transversely) from
side to side, or diagonally from corner to corner. Or in some cases we may only form
the slit upon one side of the neck, and not right across.
Or instead of forming the slot or opening in the centre of the spindle we may pass
the screw pin across the side of the spindle.
This screw pin may be made a plain pin with a head at one end, and screwed at the
other, but generally we should prefer to enlarge its diameter at each end. This our
invention may be applied to china, wood, metal, or other furniture by suitably forming
their necks of metal.
We will now further proceed to more particularly describe this our invention by
the aid of the accompanying illustrative sheet of drawings, upon which are figures and
letters of reference.
Fig. 1 is a sectional view of this our invention. Figs. 2, 3, 4, 5, 6, 7, 8, 9 & 10,
being modified details of our invention enlarged to twice the size of Fig. 1.
As will be seen we take a spindle a, say of a square section, and either fix the knob
upon the one end permanently, or we may secure the knobs at both ends according to
this our invention.
In this spindle a, we may then form a slot b, Fig. 7 or slot e, Fig. 8 or in some
cases we may provide a number of holes dd, Fig. 9, or the side cut away as shewn
in Fig. 10.
We next take the knob e, which would generally be entirely of metal, such as the
ordinary door metal knob, or it may be of wood, china, glass &c. having a metal
neck, and provided with a square hole corresponding to the spindle a.
We then cut a slit up the neck of the knob, which slit may be made right
across the neck as shown in Figs. 2, 3 & 4, or it may be only open one side as
shewn in Figs. 5 & 6.
We further provide in the neck of the knob a hole to receive a screw pin g,
Figs. 1, 2, 3, 4 or 6. This hole as will be observed is prepared in the one half or
side of the slitted neck, to receive the head part of the pin, while in the other part or
side of the slotted neck the hole is screwed.
The screw ping, may be somewhat modified in shape, as that it may be a plain pin
similar as shewn in Figs. 1, 3, 4 & 6, having an equal diameter throughout, or it may
he made having an increased diameter at the screw-thread part of the said pin as
shewn in Fig. 2.
When made of an equal diameter throughout as in Figs. 1, 3, 4 & 6 it would suit
either of the kinds of spindles shewn, Figs. 7, 8, 9 & 10; but if made with an enlarged
screw part Fig. 2, it would suit spindles Figs. 8 & 10, which are open at the end to
allow the pin when in position in the neck, to pass on to the spindle; this latter
arrangement preventing the withdrawal of the pin except when the knob is off the
spindle.
It will now be seen that upon passing the neck of knob on to the spindle
(see Figs. 7 & 9) to the desired distance, and then inserting the screw ping
Figs. 1, 3, 4 & 6, or, otherwise, first inserting the pin g. Fig. 2 into the neck of the
knob and then passing it on to the neck of the spindle Figs. 8 & 10, by screwing up
the said pin, the two slitted parts of the neck of the knob are brought closer together,

page_text: thereby firmly nipping or gripping the spindle a, and thus secures or fixes the knob
upon the spindle.
The neck of the knob being slit and closed upon the spindle gives it a springy action,
tending to resist the closing action of the screw, which springy action, lessens or
prevents the liability of the pin to shake loose.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we wish it to be understood that we
are aware that already knobs are secured to their spindles by means of screw pins
passing through such spindles, but such spindles are screwed upon their angles to
receive the knob neck, and also such necks are not split or slit, and therefore we
do not claim each of these parts in and by themselves, but what we do claim is :-
1st. The combination in the method of securing knobs to their spindles of a slit or
half slit in the neck of the knob, with a screw pin, in conjunction with a slotted spindle
Fig. 7 all substantially as herein set forth and shewn.
2nd. The combination in the method of securing knobs to their spindles, of a slitted
neck, a screw pin, in conjunction with an open slotted spindle Fig. 8, all substantially
as herein set forth and shewn.
3rd. The combination in the method of securing knobs to their spindles, of a slitted
neck, a screw pin, in conjunction with a spindle having drilled through holes Fig. 9,
as described and shewn.
4th. The combination in the method of securing knobs to their spindles, of a slitted
neck, a screw pin, in conjunction with a side shaped spindle Fig. 10, as herein described
and shewn.
