IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS TO SPINDLES
Year: 1885

page_text: I GEORGE HENRY TAYLOR The Poplars Great Crosby (Merchant,) do hereby
declare the nature of the said invention for IMPROVEMENTS IN ATTACHING DOOR
AND OTHER KNOBS TO SPINDLES to be as follows:-
:-
An arrangement or combination of parts and other Knobs to Spindles whereby
great simplicity and security in attaching the said Knobs are obtained.
The novel feature of my Invention, is the combination of a spindle with a series
of holes drilled completely through its centre, with a screw thread cut upon its
edges, and a slot cut in the flange or shoulder of the knob by means of which
combination a more secure and perfect adjustment is obtained than hy. the ordinary
method of using a screwed spindle either grooved or drilled partly through its
centre, or a plain square spindle with holes drilled completely through its centre
but without the screw thread cut upon its edges.
The Knob for one side of the door (a. fig. 1.) may be permanently fixed to the
spindle, which is square,-but upon its edges at the opposite end is cut a male
screw thread (upon which the loose knob is to be screwed) and upon two of its
sides for about two inches from the end are also drilled two sets of holes completely
through the centre, at distances of five sixteenths of an inch from the centre of
each hole, those at the side being drilled at intermediate distances between the
first set of holes, thus enabling the knob to be adjusted to the door to one thirty-
second of an inch.
The spindle holes may either be drilled quite plain to take a smooth wire pin, or
tapped with a female screw thread to take a screw, as may be preferred.
The loose Knob, (figs. 2 & 3.) is made with a round hole in its centre, (c. fig. 3)
which is tapped with a female screw thread to receive the spindle, and in its pro-
jecting flange or shoulder, are cut two slots, (d. d. fig. 3) through which a metal pin
or screw (fig. 4) is inserted into one of the holes in the spindle, thus attaching and
securing the knob firmly to the spindle.
The Pin or Screw is made the same length as the diameter of the shoulder of the
knob, so that when it is in position in the spindle, both its ends enter the slots in
the shoulder of the knob, completely securing and preventing the knob from being
rotated, and fixing it rigidly to the spindle.
The Rose (figs. 5 & 6) is also made with a projecting collar, in which is a slot E,
by means of which the metal pin or screw is placed in position in the shoulder of

page_text: the knob, and the rose is then turned half round and screwed to the door, thus
preventing the displacement of the said pin or screw.
In using my invention, the loose end of the spindle is pushed through the lock of
the door and upon it the rose is first placed, the moveable knob is then screwed on
to the spindle until in position against the door, the pin or screw is inserted into
one of the slots in the shoulder of the knob,-through the slot in the rose,-and
forced or screwed down until driven home into the spindle, when the rose being
turned half round and screwed to the door, prevents the said pin or screw from
being withdrawn or working loose.
In order to detach the knob from the spindle, it is only necessary to release the
rose from the door and remove the pin or screw, when the knob may be with-
drawn.

Improvements in Attaching Door and other Knobs to Spindles..
1 GEORGE HENRY TAYLOR The Poplars Gt Crosby nr Liverpool Iron Merchant
do hereby declare the nature of my invention for IMPROVEMENTS IN ATTACHING
DOOR AND OTHER KNOBS TO SPINDLES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My Invention consists of an arrangement or combination of parts hereinafter
described for attaching Door and other Knobs to their spindles whereby great
simplicity and security in attaching the said Knobs are obtained.
The novel feature of my Invention is the combination of a spindle with a series
of holes drilled completely through its centre, with a screw thread cut upon its
edges, and a slot cut in the flange or shoulder of the Knob by means of which
combination a more secure and perfect adjustment is obtained than by the ordinary.
method of using a screwed spindle grooved, or drilled partly through its centre, or
a plain square spindle with holes drilled completely through its centre, but without
the screw thread cut upon its edges.
The Knob for one side of the door (Fig. 1.) may be permanently fixed to the
spindle, which is square, and upon its edges-but at the opposite end thereof-is
cut a male screw-thread, (upon which the loose knob is to be screwed,) and upon
two of its sides for about two inches from the end, are also drilled two sets of holes
completely through its centre, at distances of five sixteenths of an inch apart from
the centre of each hole, those at the side of the spindle being drilled at intermediate
distances between the first set of holes, thus enabling the knob to be adjusted to
the door to a thirty second of an inch.
The spindle holes may either be drilled plain, to take a smooth wire pin, or
tapped with a female screw thread to take a screw, as may be preferred.
The loose Knob (Figs. 2 & 3.) is made with a round hole in its centre (C. Fig. 3.)
which is tapped with a female screw thread to receive the spindle and in its pro-
jecting flange or shoulder, crosswise, is cut a slot (d d. Fig. 3.) through which a
metal pin or screw (Fig. 4) is inserted into one of the holes in the spindle, thus
attaching and securing the Knob firmly to the spindle.
The Pin or screw, is made the same length as the diameter of the shoulder of the
Knob, so that when it is put into its place, both of its ends being driven into the
slot in the shoulder of the Knob, prevent the knob from turning round, and fix it
firmly to the spindle..
The Rose (Figs. 5 & 6.) is made with a projecting collar, in which is also a slot E,
by means of which, the metal pin or screw is placed in position in the shoulder of
the Knob and the Rose is then turned half round and screwed to the door, thus
preventing the displacement of the said pin or screw.
If preferred instead of the Rose, as shewn in Figs. 5 & 6, a loose metal Rose
lining may be substituted (Figs. 7 & 8.) to fit upon the shoulder of the Knob,
containing a similar slot to the before mentioned Rose, and when in position a
Ring Rose (Figs. 9 & 10.) is passed over the lining, completely concealing the mode
of attachment, both are then screwed to the door in the usual way, by means of the
screw holes provided for that purpose.

page_text: In using my Invention, the loose end of the spindle is pushed through the lock in
the door and upon it the Rose-or Rose lining-with the Ring Rose resting upon
the neck of the loose Knob,-is first placed, the moveable Knob is then screwed on
to the spindle until in position against the door, the pin or screw is inserted into
the slot in the shoulder of the Knob, through the corresponding slot in the rose-
or rose lining and forced or screwed down until driven home into the spindle,
when the rose or rose lining,-being turned half round and screwed to the door,
prevents the pin or screw from being withdrawn or working loose.
In order to detach the Knob from the spindle it is only necessary to release the
Rose from the door and remove the Pin or Screw, when the Knob may be with-
drawn.
Having explained the nature of my Invention I will proceed to describe the
accompanying drawings.
Fig. 1. represents the fast Knob permanently fixed to the spindle, which has two
sets of holes drilled at equal distances through its centre and a screw thread cut
upon its edges.
Fig. 2. represents the moveable Knob mounted with a metal collar, in the flange
or shoulder of which a slot is cut, crosswise, through its diameter.
Fig. 3. is a front view of the moveable Knob, shewing the position of the slot dd,
and the round screwed hole C to admit the spindle.
Fig. 4 represents the wire pin or screw, which secures the moveable Knob to the
spindle.
Fig. 5, represents a side view and fig. 6 a front view of the Rose with a pro-
jecting collar, and a slot E cut through it for the insertion of the metal pin or
screw.
Figs. 7 & 8. represent side and front views of a metal Rose lining, also with a
slot cut through its projecting collar,-and two screw holes in the back for
attachment to the door.
Figs. 9 & 10 represent a Ring Rose, to slide over and to cover the Rose lining
with two corresponding screw holes to screw to the door.
Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood, that I do not limit myself to
the precise details herein described and illustrated, as the same may be varied
without departing from the nature of my Invention, but I claim as my Invention,
The improvements in attaching door and other Knobs to spindles herein before
described and illustrated in the accompanying drawings, that is to say; the con-
struction of a moveable Knob with a slotted shoulder for the insertion of a wire
pin or screw, and the attachment thereof to a square spindle with holes drilled
completely through its centre on both sides, and tapped with a screw thread on its
edges.
I claim also as part of my Invention the loose metal Rose lining in combination
with the Ring Rose, made with corresponding screw holes in each, for attachment
together to the door.
