page_text: LETTERS PATENT to William Patch Wyatt, of Percy Square, Clerkenwell, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR ADJUSTING AND SECURING THE KNOES OR HANDLES OF LOCKS, LATCHES,
OR OTHER FASTENINGS."
Sealed the 7th July 1876, and dated the 5th May 1876.
PROVISIONAL SPECIFICATION left by the said William Patch Wyatt at the
Office of the Commissioners of Patents on the 5th May 1876.
WILLIAM PATCH WYATT, of Percy Square, Clerkenwell, in the County of
Middlesex. "IMPROVEMENTS IN APPARATUS FOR ADJUSTING AND SECURING THE
KNOBS OR HANDLES OF LOCKS, LATCHES, OR OTHER FASTENINGS."
According to these improvements to the screw end of the spindle of a lock, latch,
or other similar fastening a circular nut is fitted for the purpose of adjusting the fixed
handle or knob in its proper position on the door. One end of the circular nut is
inade to fit accurately into the loose knob or handle, and has a flange upon it, the
other end is made to revolve freely, and is secured to a rose which is fixed upon
the door. The loose knob is made with a square opening the size of the spindle,
and is arranged to receive the end of the circular nut. A screw thread is cut in
the knob, and a rim formed to conceal the method of fixing. In order to secure the
loose knob or handle to the spindle a revolving flanged nut is placed between tho
flange on the circular nut and the fixed rose. The fixed rose is provided with a
circular rim which has a screw thread cut on its outer sido to receive the screw
thread on the inside of the covering rose. A small opening is cut in the circular
rim to allow the revolving flanged nut to be easily turned.
Now in order to fix the knobs or handles in the first instance to the door, the screw
end of the spindle must be passed through the "follower" of the lock, the circular
nut which is secured to the fixed roso must then be turned round upon the spindle
until the fixed knob or handle is accurately adjusted in its place, when the fixed
roso may be permanently secured in its position. The loose handle must then
be placed on the end of the spindle and held firmly against the end of the
circular nut, and the revolving flanged nut must then be passed by means of a
bradawl, punch, or any suitable tool on to the screw portion of the looso knob and
driven tight home, the knobs or handles will then be firmly coupled together, the
covering roses are now placed in position, when the whole method of fixing will be
[Price 6d1

page_text: completely concealed. When it is desired to remove the handles the covering rose
to the loose handle must be turned back in the ordinary manner, the revolving flanged
nut unscrewed, the loose knob can then be removed from the spindle, the circular nut
attached to the fixed rose must be turned back until the spindle with the fixed
knob is released. The whole of the fixing portion of the furniture remains upon
the door. In those cases where a knob or handle is required on one side of a door
only, in accordance with my improvements, a screw thread is formed on the inside
of the circular rim on the fixed rose, and the revolving flanged nut is reversed by
placing it on the knob behind a flange formed on the end of the knob for that
purposes. The screw thread on the revolving flanged nut is made on the outside of
the nut instead of the inside.
In order to fix a knob on one side of a door only, in accordance with my im-
provements, it is necessary first to adjust accurately and secure the fixed rose. The
spindle must then be passed into the "follower" of the lock, the knob or handle
placed in its position on the spindle, and the revolving flanged nut screwed firmly
home. The covering rose is put on in the ordinary manner, when the fixing will
be complete.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Patch Wyatt in the Great Seal Patent Office on the 3rd November
1870.

IMPROVEMENTS IN APPARATUS FOR ADJUSTING AND SECURING THE KNOBS OR
HANDLES OF LOCKS, LATCHES, OR OTHER FASTENINOS."
My improvements in apparatus for adjusting and securing the knobs or handles
of locks, latches, or other similar fastening for doors are clearly shown in the
Drawings hereunto annexed, which I will now proceed to describe.
Figure 1 shows a section of the several parts detached, and Figure 2 a section of
the parts when in position as applied to the knobs and spindle of a door, the other
Figures show separate views of some of the parts.
To the screw end of the spindle B of a lock, latch, or other similar fastenings, a
circular nut G is fitted for the purpose of adjusting the fixed handle or knob A in
its proper position on the door. One end of the circular nut is made to fit accurately
into the loose knob or handle A' and has a flange upon it, the other end is made
to revolve freely in, and is secured or not to a rose E, which is fixed upon the door.
The loose knob A' is made with a square opening the size of the spindle B, and is
arranged to receive the end of the circular nut G. A screw thread is cut in the
knob A. to receive the brass mount H. In order to secure the loose knob or handle
A to the spindle B, a revolving flanged nut F is placed between the flange on
the circular nut G and the fixed rose E. The fixed rose E is provided with a
circular rim which has a screw thread cut on its outer side to receive the screw
thread on the inside of the covering rose C. A small opening e is cut in the circular
rim of the fixed rose E to allow the revolving flanged nut F to be easily turned.
Now in order to fix the knobs or handles in the first instance to the door
the screw end of the spindle B must be passed through the "follower" of the lock,
the circular nut G which is secured or not, as the case may be, to the fixed rose E
must then be turned round upon the spindle B until the fixed knob or handle A is
accurately adjusted in its place, when the fixed rose E may be permanently secured
in its position. The loose handle A' must then be placed on the end of the spindle
B and held firmly against the end of the circular nut G, and the revolving flanged
nut F must then be passed by means of a bradawl, punch, or any suitable tool on to
the screw on the mount to the loose knob A' and driven tight home, the knobs or
handles will then be firmly coupled together. The covering roses are now placed
in position, when the whole method of fixing will be completely concealed.
When

page_text: it is desired to remove the handles, the covering rose to the loose handle A' must
be turned back in the ordinary manner, the revolving flanged nut F unscrowed,
the loose knob can then be removed from the spindle, the circular nut G attached
(or not as the case may be) to the fixed roso E must be turned back until the
spindle with the fixed knob A is released.). In those cases where a knob or handle
is requred on one side of a door only, in accordance with my improvements, a screw
thread is formed on the inside of the circular rin on the fixed rose E, and the
revolving flanged nut F is reversed by placing it on the knob A¹ behind a flango
formed on the end of the mount to the knob for that purpose. The screw thread
on the revolving flanged nut F is made on the outside of the nut instead of the inside.
In order to fix a knob on one side of a door only, in accordanco with my im-
provements, it is necessary first to adjust accurately and secure the fixed rose E.
The spindle must then be passed into the "follower" of the lock, the knob or
handle placed in its position on the spindle, and tho revolving flanged nut F screwed
firmly home. The covering rose is put on in the ordinary manner when the fixing
will be complete.
Having thus described the naturo of my Invention and the manner of
performing or carrying the same into practice, what I claim is, the improved
arrangement, construction, and combination of the parts C, D, E, F, G, and H, for
adjusting and securing the knobs or handles of locks, latches, or other similar
fastenings to doors, substantially in the manner and for the purposes herein-before
described and represented in the Drawings annexed.
In witness whereof, I, the said William-Patch Wyatt, have hereunto set my
hand and seal, this Third day of. November, in the year of our Lord Ono
thousand eight hundred and seventy-six.
