Year: 1870

page_text: LETTERS PATENT to Thomas Peard, of the. Firm of Hart, Son,.
Peard, & Co., of Wych Street, in the County of Middlesex, and
James John Castle and Isaac Holmes, both in the Employ of the
said Firm, for the Invention of "IMPROVEMENTS IN THE APPARATUS
FOR ADJUSTING AND SECURING THE KNOBS OR HANDLES OF LOCKS, LATCHES,
AND OTHER FASTENINGS."
PROVISIONAL SPECIFICATION left by the said Thomas Peard, James
John Castle, and Isaac Holmes at the Office of the Commissioners
of Patents, with their Petition, on the 17th January 1870.
We, THOMAS PEARD, of the Firm of Hart, Son, Peard, & Co., of
Wych Street, in the County of Middlesex, and JAMES JOHN CASTLE and
ISAAC HOLMES, both in the Employ of the said Firm, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE APPARATUS
FOR ADJUSTING AND SECURING THE KNOBS OR HANDLES OF LOCKS, LATCHES, AND
OTHER, FASTENINGS," to be as follows:-
This Invention has for its object improvements in the apparatus for
adjusting and securing the knobs or handles of locks, latches, and other.
fastenings.

page_text: We make a rose or back plate with a screwed aperture to screw upon
the threaded edges of a square or other suitably shaped spindle, and such
rose or back plate has an outer flange secured to it by means of a rim
formed in the rose, and rolled or burnished over the inner edge of the
flange (but not so as to prevent the former turning freely in the latter).
The rose or back plate has also a screw thread cut on its external rim,
and a screwed collar is fitted thereto. The knob neck or the bush of
the knob or handle is fitted to a seating formed in the before-mentioned
rose, and pegs upon it project and fit into holes prepared to receive them
in the scating of the rose. The screwed collar, when in its place on the
rose, is rolled or burnished over the knob neck or the bush of the knob
or handle so as to make it a cap to prevent the removal of the knob.
In order to prevent the possibility of, the aforesaid cap becoming loose
through slamming of doors and other causes a spring is mounted on the
back of the rose or back plate and secured to it. This spring has a
projecting nib which passes through a notch or opening in the rose or
back plate and enters a notch made in the edge of the screwed cap, or in
other equivalent manner the cap is secured.
In fitting this furniture to a door, the spindle having been inserted into
the follower of the lock, the rose or back plate is screwed upon it until it
reaches the face of the door. The flange around it is then (by preference)
fixed to the door by screws passed through holes formed in its edges.
The knob with the screwed cap around its stem is then applied, the pegs
upon the knob or knob bush are inserted into the holes in the face of
the rose or back plate, and the cap is screwed on the thread upon the
rose. When the cap is screwed home the spring catch retains it, or it
is otherwise suitably secured..
* t
Another arrangement consists in making a metal disc with a screwed
aperture in the centre to screw upon the threaded edges of a square or
other suitably shaped spindle, and it has an outer rim or flange fitted
thereto. This disc holds the knob neck or the bush of the knob by
means of a flange rolled or burnished over it (but not so as to prevent
the latter turning freely in the former). In the knob neck or bush is a
sliding bolt which takes into notches in the outer face of the disc and so
locks the two, so that the one cannot turn without the other. In.fitting
this furniture to a door the bolt is released by depressing a pin which
projects from it through the edge of the knob neck or the bush for the

page_text: knob, and the disc is then turned so as to screw it on to the spindle until
it reaches the face of the door, and then the bolt is released and it locks
the disc and the knob neck or the bush of the knob together.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Peard, James John Castle, and Isaac
Holmes in the Great Scal Patent Office on the 16th July 1870. .
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, THOMAS
PEARD, of the Firm of Hart, Son, Peard, & Co., of Wych Strect, in the
County of Middlesex, and JAMES JOHN CASTLE and ISAAC HOLMES, botli
in the Employ of the said Firm, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of January, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Peard, James John Castle,
and Isaac Holmes, Her special licence that we, the said Thomas.
Peard, James John Castle, and Isaac Holmes, our executors, adminis-
trators, and assigns, or such others as we, the said Thomas Peard,
James John Castle, and Isaac Holmés, our exécutors, 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;

United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE APPARATUS
FOR. ADJUSTING AND SECURING THE KNOBS OR HANDLES OF LOCKS, LATCHES, AND
OTHER FASTENINGS," upon the condition (amongst others) that wc, the
said Thomas Peard, James John Castle, and Isaac Holmes, our exccu-
tors or administrators, by an instrument in writing under our or their
hand 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 I, the said Thomas Peard, on behalf of myself
and the said James John Castle and Isaac Holmes, do hereby declare

page_text: 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 has for its object improvements in the apparatus for
adjusting and securing the knobs or handles of locks, latches, and other
fastenings.
We make a rose or back plate with a screwed aperture to screw upon
the threaded edges of a square or other suitably shaped spindle, and such
rose or back plate has an outer flange secured to it by means of a rim
formed in the rose, and rolled or burnished over the inner edge of the
flange (but not so as to prevent the former turning freely in the latter).
The central ring nut of the rose or back plate has a screw thread cut
on its external rim, and a screwed collar is fitted thereto. The knob
neck or the bush of the knob or handle is fitted to a seating formed
in the before-mentioned rose, and pegs upon it project and fit into
holes prepared to receive them in the seating of the rose. The screwed
collar, when in its place on the rose, is rolled or burnished over the knob
neck or bush of the knob or handle so as to make it a cap to prevent
the removal of the knob. In order to prevent the possibility of the
aforesaid cap becoming loose through slamming of doors or other
causes a spring is mounted on the back of the rose or back plate, and
secured to it. This spring has a projecting nib which passes through a
notch or opening in the rose or back plate and enters a notch made
in the edge of the screwed cap, or in other equivalent manner the cap
is secured.
Figure 1 of the Drawings hereunto annexed shews a side view, and
Figure 2 a section of a knob connected to the spindle of a lock or
latch in the manner above described. The knobs at both ends of the
spindle may be connected to it in this manner, or one of the knobs may
be otherwise fixed to the spindle; a is the ring nut forming the central
part of the rose or back plate, and 6 is the outer flange of the rose or
back plate secured to the ring nut a by means of a rim a¹ formed around
the ring nut a and rolled or burnish over the inner edge of the flange
b as shown, but not closed over so tightly as to prevent the ring nut
turning freely. The flange 6 may be secured to the woodwork of a
door by ordinary wood screws, but this is not essential. The flange b
of the rose or back plate is shewn separately in section and plan view
at Figures 3 and 4, and the central ring nut is shown. separately at

page_text: Figures 5 and 6. The. knob neck c or (if the knob. is not entirely of
metal) the bush of the knob fits within a circular seating, formed
within the ring nut a, and two pins enter into any two opposite_holes
formed in the nut. as shewn at Figure 5; d is the screw collar to screw
on to the screw thread, cut around the outer circumference of the ring
nut, and rolled or burnished over the knob neck or bush of the knob
so as to form a cap to prevent the removal of the knob and hold it
securely to the ring nut a; a section and plan view of this cap are shown
separately at Figures 7 and 8, e is the spring catch by which the cap is
locked to prevent it unscrewing after it has been screwed on to the
ring nut a; this spring catch is shown separately at Figures 9 and 10.
It is held by a small rivet to the back of the nut a, as shown in the
section, Figure 2, and its projecting nib e¹ passes through a notch or
opening at the side of the ring nut and enters a small notch in the
screw cap e; when it is desired to unscrew the cap it is readily released
by pressing back the nib e of the spring and the cap can then be
unscrewed.
;
In fitting this furniture to a door, the spindle having been inserted
into the follower of the lock, the rose or back plate is screwed upon it
until it reaches the face of the door. The flange around it is then
(by preference) fixed to the door by screws passed through holes formed
in its edges. The knob with the screwed cap around its neck is then
applied, the pegs upon the knob or knob bush are inserted into the
holes in the face of the ring nut of the rose or back plate, and the cap.
is screwed on the thread upon the central ring nut of the rose. When
the cap is screwed home the spring catch retains it.
Other arrangements than that above described and shown by the
Drawings may be employed for connecting the knob neck or bush of
the knob to a ring nut carried at the centre of a rose or back plate, as
0 for example, the nut at the centre of the rose or back plate may be
formed to hold the knob neck or the bush of the knob by means of a
flange rolled or burnished over it (but not so as to prevent the latter
turning freely in the former), and in this case the knob.neck or bush
may be provided with a sliding bolt to take into notches in the outer
5 face of the ring nut and so lock the two together that the one cannot
turn without the other. In fitting this furniture to a door the bolt is
released by depressing a pin which projects from it through the edge
of the knob neck or the bush of the knob, and the rose plate is then

page_text: turned so as to screw it. on to the spindle until it reaches the face of
the door, and then the bolt is released, and it locks the ring nut of the
rose plate and the knob neck or the bush of the knob together.
Having thus described the nature of our Invention and the manner
of performing the same, we would have it understood that what we claim
as our improvements in the apparatus for adjusting and securing the
knobs or handles of locks, latches, and other fastenings is,-
First. The construction of a rose or back plato substantially as herein
described, carrying a ring nut capable of turning, freely within it, such
ring nut screwing on to the spindle and having secured to it the knob
neck or bush of the knob.
Second. The constructing apparatus for adjusting and securing the
knobs or handles of locks, latches, and other fastenings, substantially
| in. the manner shewn by the Drawings hereunto annexed.
Third. The securing the ring cap d by a spring catch e substantially
as herein described.
In witness whereof, I, the said Thomas Peard, have hereunto set
my hand and seal, this Sixteenth day of July, in the year of
our Lord One thousand eight hundred and seventy.
