Sealed the 21st June 1859, and dated the 5th January 1859.
PROVISIONAL SPECIFICATION left by the said Frederick Clark at the.
Office of the Commissioners of Patents, with his Petition, on the
5th January 1859.
I, FREDERICK CLARK, of King Street, Bloomsbury, in the County of
Middlesex, Turner, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CONNECTING KNOBS AND HANDLES TO THE SPINDLES OF LOCKS
AND LATCHES AND OTHER ARTICLES OF A LIKE NATURE," to be as follows:-
My Invention consists of a peculiar combination of parts for connecting
knobs and handles to the spindles of locks and latches and other articles of a
like nature, in which combination I propose to use a spindle having a square
transverse section and with a screw'd thread cut at its angles as has heretofore
been done. One end of this spindle should pass through a metal bush having
a square opening to correspond with the section of said spindle and also
through a cylindrical spiral spring, which may be at first expanded; the said
spindle being, retained in its position inside the said bush and spring by a
washer rivetted on end of spindle or by any other suitable contrivance, the
said bush only being fixed in a hollow chamber inside the knob or handle to
which this Invention is applied.
Having described the combination of parts relating to one end of spindle
and knob or handle, I now proceed to describe the parts relating to the other

page_text: end. On this end of spindle, which has the before-mentioned screwed thread
worked to its extremity, is placed a sliding collar, circular at the part nearest
the centre spindle and square at its opposite end, which square end is intended
to correspond with and enter into a bush, hereinafter to be described. This
collar has a transverse circular flange to facilitate its being moved on the
spindle as required for fastening to or detaching from doors; on the same end
of spindle, and at its extremity is a metal bush having a square aperture to
receive corresponding part of collar at one end and a circular orifice with
screwed thread therein to correspond with screwed thread on spindle at the
other end, this bush may be fastened in the usual manner to the knob or
handle.
In applying or using this Invention, the spindle having a knob or handle
attached, thereto with the bush and spring herein first described already fixed
on, one end is passed through door and lock or latch or any other article to
which this Invention may be applied and allowed to extend to a sufficient
distance on the opposite side of said door to allow of the collar already
described being passed on to it, and also to allow of its receiving the
remaining knob with screwed bush attached. In screwing on this knob a
withdrawing impulse is given in addition to the rotary motion necessary to
join the male and female screws in order to contract the spring on the opposite
end of spindle, which impulse is maintained until the knob is screwed suffi-
ciently near to the door to allow of the counteraction of the spring on opposite.
end of spindle, bringing the square aperture in the bush over the square end of
collar already described and close to the door; in which permanent position,
the knob will no longer rotate on the spindle, but act in conjunction with the
same on the follower of lock, latch, or other article to which this Invention
may be applied. The parts described as being applied to each separate end
of spindle may be combined on one end to operate in the same manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Clark in the Great Seal Patent Office on the 3
4th July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
CLARK, of King Street, Bloomsbury, in the County of Middlesex, Turner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 3
Patent, bearing date the Fifth day of January, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of

page_text: Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick Clark, Her special licence that I, the said Frederick Clark;
my executors, administrators, and assigns, or such others as I, the said Frederick
Clark, 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 "IMPROVEMENTS IN
CONNECTING KNOBS AND HANDLES TO THE SPINDLES OF LOCKS AND LATCHES AND
OTHER ARTICLES OF A LIKE NATURE," upon the condition (amongst others) that
I, the said Frederick Clark, my executors or administrators, by an instru-
ment 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frederick Clark, do hereby declare
the nature of my said Invention, 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 a peculiar combination of parts for connecting
knobs and handles to the spindles of locks and latches and other articles of a
like nature, in which combination I propose to use a spindle (A, Fig. 1,)
having a square transverse section, and with a screw thread cut at its angles
as has heretofore been done. One end of this spindle should pass through a
metal bush (B, Fig. 1,) having a square opening to correspond with the
section of said spindle, and also through a cylindrical spiral spring (C, Fig.1,).
which may be at first expanded, the said spindle being retained in its position
inside the said bush and spring by a washer (D, Fig. 1,) rivetted on one end
of spindle or by any other suitable contrivance; the said bush only being fixed.
in a hollow chamber (as in Fig. 1, E,) inside the knob or handle to which the.
Invention is applied.
Having described the combination of parts relating to one end of spindle
and knob or handle, I now proceed to describe the parts relating to the other
end. On this end of spindle which has the before-mentioned screw thread
worked to its extremity is placed a sliding collar (F, Fig. 1,) circular at the
part nearest the centre of spindle and square at its opposite end, which
square end is intended to correspond with and enter into a bush (H, Fig. 1),
herein-after to be described; this collar has a transverse circular flange to

page_text: facilitate its being moved on the spindle as required, for fastening to or
detaching from doors, and to retain the collar between the rose and the door.
On the same end of spindle is a metal bush (H, Fig. i,) having a square
aperture to receive corresponding part of collar at one end, and a circular
orifice with screw thread therein to correspond with screw thread on spindle;
this bush may be fastened in the usual manner to the knob or handle.
In applying or using this Invention, the spindle A, having a knob or handle
attached thereto with the bush B and spring C already fixed on one end is
passed through door and lock, or latch, or other article to which it may be
applied, and allowed to extend to a sufficient distance on the opposite side of
said door to allow of the collar F already described being passed on to it, and also
to allow of its receiving the remaining knob or handle with screwed bush H
attached. In screwing on this knob, a withdrawing impulse is given in
addition to the rotary motion necessary to join the male and female screws in
order to contract the spring on the opposite end of spindle, which impulse"
is maintained until the knob is screwed sufficiently near to the door (which
may be of any thickness) to allow of the contraction of the spring bringing
the square aperture in the bush Hover the square end of collar already
described and close to the door, in which permanent position the knob will no
longer rotate on the spindle, but act in conjunction with the same on the
follower of lock, latch, or other article to which this Invention may be
applied. The parts described as being applied to each separate end may be
combined on one end to operate in the same manner.
Reference is made in the foregoing to the Drawing hereunto annexed,
which represents, partly in section, in Fig. 1, a spindle and two knobs as
fastened to a door; and in Figures 2, 3, 4, 5, 6, 7, the various parts separately;
viz Fig. 2, section of spindle A; Fig. 3, plan of bush B; Fig. 4, spring C;
Fig. 5, washer D; Fig. 6, plan of collar F; Fig. 7, plan of bush H.
The principle of construction of this Invention may be embodied in a variety
of forms to suit the materials used, and to suit the locks, latches, or other
articles to which it may be applied.
In witness whereof, I, the said Frederick Clark, have hereunto set my
hand and seal, this Fourth day of July, in the year of our Lord One
thousand eight hundred and fifty-nine.
FREDERICK CLARK. (L.S.)
