AN IMPROVED MODE OF ATTACHING DOOR KNOBS TO THEIR SPINDLES
Year: 1863

page_text: LETTERS PATENT to Josiah Hulse, and Joseph Lawrence, both of
Willenhall, in the County of Stafford, Wood Turners, for the Invention
of "AN IMPROVED MODE OF ATTACHING DOOR KNOBS TO THEIR SPINDLES."
Sealed the 10th May 1864, and dated the 16th November 1863.
PROVISIONAL SPECIFICATION left by the said Josiah Hulse and
Joseph Lawrence at the Office of the Commissioners of Patents,
with their Petition, on the 16th November 1868.
We, JOSIAH HULSE and JOSEPH LAWRENCE, both of Willenhall, in the
County of Stafford, Wood Turners, do hereby declare the nature of the
said Invention for "AN IMPROVED MODE OF ATTACHING DOOR KNOBS TO THEIR
SPINDLES," to be as follows (that is to say) :-
The object of this Invention is to dispense with the use of screws through
the neck of the knob, and also to better secure the said knobs to their
spindles, and to prevent them from working or becoming loose.
The mode of carrying our Invention into effect is this: we secure one knob
in the ordinary manner to the fast end of a square spindle, which at its other
end and to a proper distance upon it has a screw thread cut on each of its
angles, the four flat sides being hollowed or made concave, (or any other

page_text: adjustable spindle may be employed). A brass or other metal collar of
suitable construction is then provided, the inside of which has a thread cut to
correspond with the thread on the spindle. The collar being now screwed
upon the spindle to the required distance is made fast by means of a small
screw, which is driven through the collar until the head of the screw is flush
with it, the other or pointed end of the screw taking into one of the hollow
sides of the spindle, and so securing the collar to the spindle. The collar has
also a thread cut on its outside, and to receive this collar the interior of the
knob is made hollow and has a thread or worm to correspond with the thread
on the outside of the collar. (When a non-metallic knob is employed a piece
of metal is inlaid therein and upon this the thread is cut). The knob is then
screwed upon the collar just described and secures itself thereto by means of
a small click spring or catch with which the collar is provided and into which
the neck of the knob takes when screwed to the proper distance. In fixing
the knobs to a door we proceed thus :-One knob being secured to one end of
the spindle, the other end of the spindle is passed through the door and lock
or catch, on this loose end is screwed the metal collar to any distance, which
the thickness of door may require, the collar is then secured to the spindle by
means of the small screw as already described. The knob is afterwards
screwed upon the collar, and when turned to the proper pitch the catch or
spring will take in or engage with it and so secure it effectually. The screw
which secures the collar to the spindle is always screwed flush with it, as has
been mentioned, the advantage of this being that as the knob is afterwards
screwed upon the said collar (when it closely covers it), the screw is
effectually prevented from ever becoming loose as is frequently the case in the
present mode of securing adjustable spindles.
In carrying out this Invention any pattern knob and the ordinary kind of
rose may be employed, and it can be applied to all descriptions of knobs,
whether wood, brass, china, glass, or any other kind which it may be
desirable to use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Josiah Hulse and Joseph Lawrence in the Great Seal
Patent Office on the 14th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSIAH
HULSE and JOSEPH LAWRENCE, both of Willenhall, in the County of Stafford,
Wood Turners, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Josiah Hulse and Joseph Lawrence, Her special licence that
we, the said Josiah Hulse and Joseph Lawrence, our executors, adminis-
trators, and assigns, or such others as we, the said Josiah Hulse and
Joseph Lawrence, 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 "AN
IMPROVED MODE OF ATTACHING DOOR KNOBS TO THEIR SPINDLES," upon the
condition (amongst others) that we, the said Josiah Hulse and Joseph
Lawrence, our executors or administrators, by an instrument in writing
under our, 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.
NOW KNOW YE, that we, the said Josiah Hulse and Joseph Lawrence,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say):-
The object of this Invention is to dispense with the use of screws
through the neck of the knob, and also to better secure the said
knobs to their spindles, and to prevent them from working or becoming
loose.
The mode of carrying our Invention into effect is this:-We secure one
kuob in the ordinary manner to the fast end of a square spindle, which at its
other end, and to a proper distance upon it, has a screw thread cut on each
of its angles, the four flat sides being hollowed or made concave (or any other
adjustable spindle may be employed). A brass or other metal collar of
suitable construction is thon provided, the inside of which has a thread cut to
correspond with the thread on the spindle. The collar being now screwed
upon the spindle to the required distance is made fast by means of a small
screw, which is driven through the collar until the head of the the screw is flush
with it, the other or pointed end of the screw (when the spindle employed is

page_text: one of the kind just described) taking into one of its hollow sides, and so
securing the collar to the spindle. The collar has also a thread cut on its
outside, and to receive this collar the interior of the knob is made hollow, and
has a thread or worm to correspond with the thread on the outside of the
collar. (When a non-metallic knob is employed a piece of metal is inlaid
therein, and upon this the thread is cut). The knob is then screwed upon
the collar just described, and secures itself thereto by means of a small click
spring or catch, with which the collar is provided, and into which the neck of
the knob takes when screwed to the proper distance. In fixing the knobs to
a door we proceed, thus:-One knob being secured to one end of the spindle,
the other end of the spindle is passed through the door and lock or catch, on
this loose end is screwed the metal collar to any distance which the thickness
of door may require, the collar is then secured to the spindle by means of the
small screw, as already described. The knob is afterwards screwed upon the
collar, and when turned to the proper pitch the catch or spring will take in
or engage with it, and so secure it effectually. The screw which secures the
collar to the spindle is always screwed flush with it, as has been mentioned,
the advantage of this being that as the knob is afterwards screwed upon the
said collar (when it closely covers it), the screw is effectually prevented from
ever becoming loose, as is frequently the case in the present mode of securing
adjustable spindles.
That our Invention may be better understood, we have annexed Drawings
thereof, which we will now describe.
Fig. 1 is a side elevation of the two knobs upon the spindle; Fig. 2 is a
longitudinal section; Fig. 3 is an end elevation of the spindle and the collar,
containing the spring catch, the knob being removed; Fig. 4 is a detail
showing an extra safety piece fitting the square of the spindle, which in some
cases it may be useful to provide.
In carrying out this Invention any pattern knob and the ordinary kind of
rose may be employed, and it can be applied to all descriptions of knobs,
whether wood, brass, china, glass, or any other kind which it may be desirable
to use.
Having now described the nature of our Invention, and the manner in
which the same is to be carried into effect, we desire it to be understood that
we do not limit ourselves to the precise means or appliances herein-before
described, as these may be varied or modified to some extent without depart-
ing from the nature of our Invention; but what we claim as the Invention
to be protected by the herein-before in part recited Letters Patent, is, the

page_text: improved mode of attaching door knobs to their spindles, substantially as
herein-before set forth and described.
In witness whereof, we, the said Josiah Hulse and Joseph Lawrence,
have hereunto set our hands and seals, this Thirteenth day of May,
in the year of our Lord One thousand eight hundred and sixty-
four.
