Year: 1874

page_text: LETTERS PATENT to Edward Vernon Bailey, of Birmingham, in the.
County of Warwick, Brassfounder, for the Invention of "IMPROVE-
MENTS IN FIXING DOOR AND OTHER KNOBS,
Sealed the 5th December 1874; and dated the 24th June 1874.
PROVISIONAL SPECIFICATION left by the said Edward Vernon Bailey
at the Office of the Commissioners of Patents, with his Petition,
on the 24th June 1874.
I, EDWARD VERNON BAILEY, of Birmingham, in the County of
Warwick, Brassfounder, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN FIXING DOOR AND OTHER KNOBS," to be as
follows:-
My Invention consists of the construction and arrangements or combi-
nations of parts, herein-after described, for fixing door and other knobs;
whereby the fixing of the knob to the door and to the latch or other.
spindle is effected in a simpler and more effectual manner than by the
ordinary arrangement, and a less number of parts are required.

page_text: My Invention is particularly applicable to mortice looks, and I will
first describe it as used in connection with a mortice lock.
The neck of the knob is prolonged beyond the flange or shoulder for
the rose, and in the said prolonged part an annular groove is made. The
knob is provided with the usual square hole which takes upon the square
spindle of the latch. The knob is fixed to the door and to the latch
spindle by means of a rose and a saddle or forked plate, which plate
takes into the annular groove in the prolonged neck of the knob. The
said saddle or forked plate consists of a circular disk of metal having in
it a cross opening passing from the circumference to a short distance
beyond the centre of the disk, the said cross opening being of a size
proper to fit accurately in the annular groove in the prolonged neck of
the knob. The rose is situated behind the said saddle or forked plate,
and the said plate and rose after the knob has been passed on to the
square spindle are fixed to the door by screws passed through corre-
sponding holes in the said rose and saddle plate. By this means the
knob is capable of turning freely in the fixed rose and saddle piece, and
the said knob is fixed with great steadiness to the door and to the latch
spindle. The knobs at both ends of the spindle are attached to the door
and spindle in the way described.
Instead of using a saddle plate and rose, as described, a thick rose
may be used having across its inner face in the direction of a diameter
a dovetail recess, the said recess fitting loosely the annular groove in the
prolonged neck of the knob. By means of dovetail cotters engaged
between the sides of the dovetail recess in the rose and the annular
groove in the neck of the knob the rose is connected to the knob, the
said knob being capable of freely rotating in the rose. The rose is fixed
to the door by screws, as herein-before described.
In applying my Invention to rim locks or latches it is necessary that
the spindle at the lock or latch end should be secured to the said lock or
latch, so as to be incapable of a sliding motion. I effect this by the
following combination of parts:-I use a square spindle, partly plain
and partly screwed, the screwed part extending at the lock or latch end
sufficiently far to reach the follower of the lock or latch. Before fixing
the lock or latch to the door the spindle with the fixed knob on, one end
is passed through the follower, and a washer with a square hole in it is
placed on the spindle and pushed forward until it abuts against the

filed by the said Edward Vernon Bailey in the Great Seal Patent
Office on the 14th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
VERNON BAILEY, of Birmingham, in the County of Warwick, Brass-
founder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of June, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edward Vernon Bailey, Her special license
that I, the said Edward Vernon Bailey, my executors, administrators, and
assigns, or such others as I, the said Edward Vernon Bailey, 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
FIXING DOOR AND OTHER KNOBS," upon the condition (amongst others) that
I, the said Edward Vernon Bailey, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and

page_text: 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 I, the said Edward Vernon Bailey, 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 :-
-
My Invention consists of the construction and arrangement or combi-
nation of parts, herein-after described, for fixing door and other knobs,
whereby the fixing of the knob to the door and to the latch or
other spindle is effected in a simpler and more effectual manner
than by the ordinary arrangement, and a less number of parts are
required.
I will describe my Invention as used in connection with a mortice
lock.
The neck of the knob is prolonged beyond the flange or shoulder for
the rose, and in the said prolonged part an annular groove is made. The
knob is provided with the usual square hole, which takes upon the
square spindle of the latch. The knob is fixed to the door and to the
latch spindle by means of a rose and a saddle or forked plate, which
plate takes into the annular groove in the prolonged neck of the knob.
The said saddle or forked plate consists of a circular disc of metal having
in it a cross opening passing from the circumference to a short distance
beyond the centre of the disc, the said cross opening being of a size
proper to fit accurately in the annular groove in the prolonged neck of
the knob. The rose is situated behind the said saddle or forked plate,
and the said plate and rose, after the knob has been passed on to the
square spindle, are fixed to the door by means of screws passed through a
corresponding holes in the said rose and saddle plate. By this
means the knob is capable of turning freely in the fixed rose and saddle
plate, and the said knob is fixed with great steadiness to the door and to
the latch spindle. The knobs at both ends of the spindle are attached
to the door and spindle in the way described.
I will now proceed to describe, with reference to the accompanying
Drawing, the manner in which my Invention may be performed,

page_text: Figure 1 represents partly in section and partly in clevation the pair
of knobs of a mortice lock fixed to the latch spindle of the said lock
and to the door according to my Invention.
of knobs of a mortice lock fixed to the latch spindle of the said lock
and to the door according to my Invention.
Figure 2 represents in elevation one of the said knobs.
Figure 3 represents in section and back elevation the rose and saddle
or forked plate combined together in the positions they occupy when
in use.
Figure 4 represents the rose separately, and Figure 5 represents the
saddle or forked plate separately.
a, b, are the two knobs of the mortice lock fixed on the ends of the
latch spindle c, which is square in cross section as usual. As the two
knobs a, b, are provided with like parts, and are fixed in the same
manner to the spindle and door, I will only describe the fixing of the
knob a.
In the prolonged neck 63 of the knob a is an annular groove d, best
seen in Figure 2. In the said knob is a square hole e, which takes upon
the square spindle c; f is the rose and g is the saddle or forked plate,
by means of which, in combination with the said rose, the knob a is
fixed to the end of the latch spindle c and to the door h. The opening
g in the saddle or forked plate g is of a size proper to fit in the annular
groove d in the prolonged neck 62, and when the said plate g is fixed the
neck of the knob turns freely in the said opening 92. In the said saddle
plate g are holes i, i, and in the rose fare holes k, k, similarly arranged,
through which holes i and k in the plate and rose screws are passed for
fixing the said plate and rose to the door. The rosef has the hollow
figure shown in the sectional views, and the saddle plate g fits in the
hollow back of the rose so as to completely fill it..
In fixing the knob a to the spindle and door the said knob with the
rose f placed over the neck of the said knob is passed on to the pro-
truding end of the spindle c until the face of the prolonged part b² of
the said neck abuts against the surface of the door h. The saddle or
forked plate g is then engaged by a sliding motion with the annular
groove d in the neck of the knob, that is, the slot or opening g² in the
middle of the said saddle plate g is made to embrace the neck at the
bottom of the said groove. The rose f is now moved forward so as to
cover the outer face and edge of the saddle plate g and its holes k, k,

page_text: brought opposite the holes i, i, in the saddle plate g. By passing screws
through the said holes of the rose and saddle plate the said parts ƒ and g
are attached to the door, and the knob a is very firmly and with great
steadiness fixed to the door and spindle, the knob being capable of
rotating freely in the fixed rose and plate for working the latch.
The manner in which the saddle plate g fixes the knob while per-
mitting it to have the necessary rotatory motion for working the latch
will be understood by an examination of Figure 1.
The other knob 6 is fixed in a similar way to the knob a, and like parts
are marked with the same letters of reference.
The rose and saddle plate g, instead of being loose or disconnected
before the knob a is fixed to the spindle and door, may be secured
together and to the knob a before the said knob is fixed to the spindle
and door. For this purpose the saddle plate g is engaged with the
groove d in the neck of the knob a, and the rose f is connected to the 1
said saddle plate g by making a screw on its flange take upon a screw
on the edge of the saddle plate, or by soldering the rose and plate
together or otherwise securing them together, the two parts f, g, being
so secured together that their screw holes coincide.
In connecting the combined rose saddle plate and knob to the door
and latch spindle it is only necessary to place the knob on the end of
the spindle and pass screws through the rose and plate into the door.
Great simplicity is thereby obtained in the fixing of the latch furniture,
and the danger of the parts of the said furniture becoming separated is
avoided.
My Invention is applicable to knobs made of metal and china or other
non-metallic material.

In the Drawing the knobs are represented as being made of china or
other non-metallic material, the necks of the knobs having metal
mounts m, which carry the parts in which the annular grooves d are a
made.

Although my Invention is particularly applicable to the fixing of the
knobs of mortice locks, yet it may also be applied to the fixing of other
knobs.
Having now described the nature of my Invention and the manner in a
which the same is to be performed, I wish it to be understood that I do

page_text: not limit myself to the precise details herein described and illustrated,
as the same may be varied without departing from the nature of my
Invention, but I claim as my Invention the improvements in fixing door
and other knobs, herein-before described and illustrated in the accom-
panying Drawing, that is to say, the combination of the rose f and
saddle or forked plate g, g³, with the annular grooved in the prolonged
neck of the knob, in which groove the said saddle or forked plate takes,
the said saddle or forked plate being fixed to the door and latch spindle
by screws passed through the rose and the said saddle or forked plate,
substantially as described and illustrated.
In witness whereof, I, the said Edward Vernon Bailey, have here-
unto set my hand and seal, this Tenth day of December, in the
year of our Lord One thousand eight hundred and seventy-
foun
