Year: 1864

page_text: LETTERS PATENT to John Hinks, of Birmingham, in the County of
Warwick, Manufacturer, and Joseph Lester Hinks, of Birmingham
aforesaid, Manufacturer, for the Invention of "IMPROVEMENTS IN ATTACHING
DOOR AND OTHER KNOBS TO SPINDLES."
Sealed the 30th September 1864, and dated the 22nd July 1864.
PROVISIONAL SPECIFICATION left by the said John Hinks and Joseph
Lester Hinks at the Office of the Commissioners of Patents, with their
Petition, on the 22nd July 1864.
We, JOHN HINKS, of Birmingham, in the County of Warwick, Manu-
facturer, and JOSEPH LESTER HINKS, of Birmingham aforesaid, Manufacturer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
ATTACHING DOOR AND OTHER KNOBS TO SPINDLES," to be as follows:-
Our Invention consists of the improvements herein-after explained in
attaching door and other knobs to spindles, which improvements are especially
applicable to the attaching of knobs to spindles in cases where it is desirable
to be able to fix the knob to a greater or less distance on the spindle as in
the case of spindles of locks and latches. Our improvements are, however,

page_text: applicable to the attaching of knobs to spindles for other purposes, such
as the knobs and spindles used for opening drawers.
We will describe our Invention in connection with the knobs and spindle of
a door lock or latch. The knob at one end of the spindle, which is ordinarily
fixed, may be attached in the usual way; that at the other end of the spindle,
which requires to be made capable of attachment at a greater or less distance on
the spindle, we attach to the spindle in the following manner:-The end of the
spindle is square and a screw thread is cut on the angles of the said spindle.
The neck of the knob has a concave screw made in it which screw takes on to
the screw on the angles of the spindle. The knob is screwed to the required
place on the spindle and is fixed in the following manner:-In the shoulder of
the knob a hole is drilled parallel to the face of the said shoulder, and passing
from a point on the edge of the shoulder to a nearly opposite point on the said
edge. The said hole is not in the direction of a diameter of the shoulder of the
knob but parallel to a diameter of the said shoulder, that is, in the direction of
a chord to the said circular shoulder. The said hole crosses one side of the
opening in the axis of the knob through which the spindle passes. When the
knob has been screwed to the required distance on the spindle and a pin is
put into the hole passing across the shoulder of the knob, that portion of the
said pin which passes through the hole in the axis of the knob lies parallel
to one of the sides of the square spindle and prevents the rotation of the knob
on the spindle. The knob is thereby fixed in its place. The said pin may
either be fixed in the hole by being driven therein or it may be made to screw
therein. The knob at each end of the spindle may be fixed in the way de-
scribed. In the case of china or non-metallic knobs we employ a metallic
bush or collar in the neck of the knob, in which collar the hole is made for
fastening the knob.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jobn Hinks and Joseph Lester Hinks in the Great Seal
Patent Office on the 18th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jonn
HINES, of Birmingham, in the County of Warwick, Manufacturer, and JOSEPH
LESTER HINKS, of Birmingham aforesaid, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of July, in the year of our

page_text: Lord One thousand eight hundred and sixty-four, in the twenty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said John Hinks and Joseph Lester Hinks, Her special
licence that we, the said John Hinks and Joseph Lester Hinks, our executors,
administrators, and assigns, or such others as we, the said John Hinks
and Joseph Lester Hinks, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS TO SPINDLES," upon the
condition (amongst others) that we, the said John Hinks and Joseph Lester
Hinks, our executors or administrators, by an instrument in writing under
our, or their hands and seals, or under the hand and seal of one of us or them,.
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Hinks and Joseph Lester Hinks,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
Our Invention consists of the improvements herein-after explained in
attaching door and other knobs to spindles, which improvements are especially
applicable to the attaching of knobs to spindles in cases where it is desirable
to be able to fix the knob to a greater or less distance on the spindle, as in the
case of spindles of locks and latches. Our improvements are, however,
applicable to the attaching of knobs to spindles for other purposes, such as the
knobs and spindles used for opening drawers.
We will describe our Invention in connection with the knobs and spindle
of a door lock or latch. The knob at one end of the spindle, which is ordinarily
fixed, may be attached in the usual way; that at the other end of the spindle,
which requires to be made capable of attachment at a greater or less distance
on the spindle, we attach to the spindle in the following manner :-The end of
the spindle is square and a screw thread is cut on the angles of the said
spindle. The neck of the knob has a concave screw made in it which screw
takes on to the screw on the angles of the spindle. The knob is screwed to
the required place on the spindle and is fixed in the following manner :-In

page_text: ,the shoulder of the knob a hole is drilled or otherwise made parallel to the
face of the said shoulder and passing from a point on the edge of the shoulder
to a nearly opposite point on the said edge. The said hole is not in the
direction of a diameter of the shoulder of the knob but parallel to a diameter
of the said shoulder, that is in the direction of a chord to the said circular
shoulder. The said hole crosses one side of the opening in the axis of the
knob through which the spindle passes. When the knob has been screwed
to the required distance on the spindle and a pin is put into the hole passing
across the shoulder of the knob, that portion of the said pin which passes
through the hole in the axis of the knob lies parallel to one of the sides of the
square spindle and prevents the rotation of the knob on the spindle. The
knob is thereby fixed in its place. The said pin may either be fixed in the
hole by being driven therein or it may be made to screw- therein. The knob
at each end of the spindle may be fixed in the way described, In the case of
china or non-metallic knobs we employ a metallic bush or collar in the neck
of the knob, in which collar the hole is made for fastening the knob.
Having explained the nature of our Invention, we will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in elevation a pair of metallic door knobs, the moveable
knob of which is attached to the spindle according to our Invention, the rose
of the said moveable knob being omitted; Figure 2 represents the same with
the moveable knob partly in longitudinal section and partly in elevation;
Figure 3 is a front elevation of the moveable knob; and Figure 4 is a trans-
erse section of the same taken through the line a of Figure 1. The same
letters indicate the same parts in Figures 1, 2, 3, and 4.
bis the square spindle having a screw thread cut on its angles at one end,
and c and d are the fixed and moveable knobs respectively of the spindle; the
knob c being fixed to one end of the spindle in the usual way, and the move-
able one d being attached according to our Invention to the other end of the
spindle and adjusted thereon in the following manner:-The neck e of the
knob has a concave screw made in its axis, which screw takes on to the screw
on the angles of the spindle b. The knob d is screwed to the required place
on the spindle b and is fixed by a pin g in the manner herein-after explained.
The front of the neck e of the knob is provided with a circular shoulder h, in
which shoulder a hole i is made (best seen in Figure 4 and also indicated
in dotted lines in Figure 3), the said hole i being situated parallel to the
face of the said shoulder and passing from a point on the edge of the said

page_text: shoulder to a nearly opposite point on the said edge, as will be understood
by an examination of Figures 3 and 4. The said hole i is not in the
direction of a diameter of the shoulder h, but is parallel to a diameter of the
said shoulder, that is, the hole i passes across the circular shoulder h in the
direction of a chord to the said shoulder, the said hole also crossing one side
of the screwed opening f in the axis of the knob (see Figure 4) through
which the spindle 6 passes. After the knob d has been screwed to the
required distance on the spindle b, the pin 9 is put into the hole i in the
shoulder h; that portion of the said pin which passes through the hole i and is
situated in the axis fof the knob lying parallel to or against one of the sides
of the square spindle b, as represented in Figure 4. The knob is thereby fixed
in its place and the rotation of the knob on the spindle prevented. The pin ġ
may either be driven into the hole i or it may be screwed therein. The fixed
knob c at the opposite end of the spindle b may be secured thereto in the way
described with respect to the knob d. In applying this part of our Invention
to china or non-metallic knobs we employ a metallic screw, bush, or collar fixed
in the neck of the knob, in which collar the hole is made for fastening the
knob to the spindle.
Figure 5 represents, partly in elevation and partly in longitudinal section, a
china or non-metallic knob attached to its spindle according to our Invention;
and Figure 6 is an elevation of the same.
is the china or non-metallic knob, in the axis of which a screwed stem
or bush is fixed in any convenient way, in which screwed stem the spindle m
works. The said stein or bush is provided with a collar or circular shoulder n
similar to the circular shoulder h in the case of metallic knobs. In the
shoulder and stem a hole is made in the direction of a chord to the said
shoulder, through which hole the fastening pin p is passed for attaching the
knob k to the spindle m in the manner herein-before described with respect to
metallic knobs.
Having now described the nature of our Invention, and the manner in
which the same is to be performed, we wish it to be understood that we do
not limit ourselves to the precise details herein described and illustrated in
the accompanying Drawing, as the same may be varied without departing
from the nature of our Invention; but we claim as our Invention the improve-
ments in attaching door and other knobs to spindles herein-before described
and illustrated in the accompanying Drawing, that is to say, by means of a
pin, plain or screwed, passed through a hole made in a shoulder on the neck
of the knob, the said hole passing through the said shoulder in the direction

page_text: of a chord to the said shoulder, the said pin bearing against one of the sides
of the square spindle so at to prevent the rotation of the knob on the spindle,
or in the case of non-metallic knobs passing a pin through a hole made in the
direction herein-before described in a screwed metallic bush or shoulder fixed
in the neck of the knob.
In witness whereof, we, the said Jobn Hinks and Joseph Lester Hinks,
have hereunto set our bands and seals, this Sixteenth day of January
in the year of our Lord One thousand eight hundred and sixty-five.
