LETTERS PATENT to Thomas Nott, of Green Street, Oxford Street,
in the County of Middlesex, for the Invention of “IMPROVED MEANS
OF AND APPLIANCES FOR SECURING HANDLES OR KNOBS, WHEELS, DISCS, AND
Scaled the 20th March 1874, and dated the 8th October 1873.
PROVISIONAL SPECIFICATION left by the said Thomas Nott at the
Office of the Commissioners of Patents, with his Petition, on the
8th October 1873.
I, THOMAS NOTT, of Green Street, Oxford Street, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVED MEANS OF AND APPLIANCES FOR SECURING HANDLES OR KNOBS, WHEELS,
DISCS, AND OTHER ARTICLES UPON SPINDLES AND SHAFTS," to be as follows:-
-
This Invention relates to certain means of securing knobs, wheels,
discs, and other articles upon spindles and shafts, and consists in
splitting, cutting, or otherwise dividing the end of the spindle or shaft,

page_text: to receive a tapered screw, the end of the spindle or shaft having a
tapped hole in it to receive the tapered screw.
The slitting or dividing of the spindle end may be across the body to
divide the side faces or across the corners, so that the side faces can
be expanded to grip the handle, knob, wheel, or other article placed 5
upon it.
I do not in all cases divide say all the sides, as any one or more of
them may be divided in any suitable manner, and as found necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
•
filed by the said Thomas Nott in the Great Seal Patent Office on
the 21st March 1874,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
NOTT, of Green Street, Oxford Street, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of October, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give, and
grant unto me, the said Thomas Nott, Her special license that I
the said Thomas Nott, my executors, administrators, and assigns, or
such others as I, the said Thomas Nott, my 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 "IMPROVED MEANS OF. AND APPLIANCES
FOR SECURING HANDLES OR KNOBS, DISCS, AND OTHER ARTICLES UPON SPINDLES
AND SHAFTS," upon the condition (amongst others) that I, the said
Thomas Nott, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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..

page_text: NOW KNOW YE, that I, the said Thomas Nott, 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:—
This Invention consists in improved means of and appliances for
securing handles, knobs, discs, wheels, and other articles upon spindles
and shafts requiring adjustment, whereby the handles, knobs, discs,
wheels, or other articles may be fixed or removed from the spindle or
shaft in a more expeditious manner than heretofore, and whereby door
handles and knobs are rendered easily adjustable to any ordinary
thickness of door.
In the following description of my Invention, and in the accom-
panying Drawings, I shall confine myself to its application to door'
spindles, which will render sufficiently obvious the means of adapting it
to securing wheels, discs, and other similar articles on their spindles or
shafts.
To carry out my Invention I proceed as follows:-I cast or otherwise
fix a handle or knob on one end of a lock, spindle, or shaft, and in thẻ
other end of such lock, spindle, or shaft I drill a hole to any convenient
depth, and the hole thus drilled is then screwed or tapped for its entire
length. I then cut or split such drilled end of the spindle in two or
more parts, such splits or cuts extending down to the bottom of such
drilled hole, and I then insert therein a taper screw pin which I term a
screw wedge."
65
The handle or knob to be fixed on the spindle is formed with a squaro
holo therein to receive the spindle or shaft, the sides of such holo being
inclined so that the aperture is smallest at the top and gradually widens
the further it passes into the knob. The handle or knob being now put
on to the spindle or shaft I insert the screw, pin, or wedge through the
centre of the handle or knob into the drilled hole in the spindle, and by
screwing the "
screw wedge" or pin into its place as far as the thickness
of the door will permit, the four corners of the split spindle are forced
out and firmly wedged against the four angles of the square hole in the
handle or knob, and when so fixed it forms a dovetail, and thus firmly
and securely fastens the handle or knob on to its spindle or shaft, and
thoroughly obviates all liability to its becoming loose or detached by
wear and use as now frequently happens.

page_text: Figure 1 shews a view of a lock spindle 6 with a handle or knob a
fixed to one end thereof, and having its other end cut into four parts
(two only of which are shewn in the Drawing).
Figure 2 is a plan view of the end of the spindle so cut into such four
parts; and Figure 3 is a plan view of a metal plate and socket c, with
which the knob a is provided, and through which one end of the spindle
passes.
Figure 4 is a sectional view of the knob a and spindle b, shewing the 1
hole and screw-thread drilled therein; and Figure 5 is a view of the pin
or screw wedge" & fitting into the same.
Figure 6 is a view of the spindle with the two knobs or handles a, a¹,
fitted thereto complete. The dotted parts in this Drawing indicate the
method of fixing the two knobs on the spindle, the dotted part e in :
the knob a shewing an ordinary screw with which this end of the spindle
is provided, so as to fit readily into the knob (but in cases where it is
made of glass or porcelain any suitable and well-known means of
fastening it thereto may be used) and the dotted lines e¹, e¹, indicate the
position of the metal plate and socket c, whilst the dotted parts e³, e³, 1
indicate the screws, by means of which such metal plate and socket is
fastened to the knob or handle. The dotted portions in the knob or
handle a¹ shew the "screw wedge" & inserted into the split end of the
spindle or shaft, and screwed home as far as the thickness of the door
will permit, and the position of such "screw wedge" in the head of the
knob when thus inserted; and Figure 7 is a plan view of the knob a¹
with the "screw wedge" or pin d so inserted, but where the handles or
knobs are made of porcelain or glass as before mentioned the orifice left
therein for the passage of the screw pin d may be covered with an
ornamental metal plate or otherwise concealed by any suitable device.

page_text: Having now particularly described and ascertained the nature of my
said Invention, and the manner of performing the same, I would have
it understood that what I claim as my Invention is, an improved means
of and appliances for securing handles or knobs, wheels, discs, and other
articles upon spindles and shafts, substantially in the manner herein-
before described.
In witness whereof, I, the said Thomas Nott, have hereunto set my
hand and seal, this 17th day of March, in the year of our Lord
One thousand eight hundred and seventy-four.
