I RICHARD GEORGE EVERED of N° 52 Harborne Road Birmingham in the
County of Warwick Brassfounder do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CONNECTING DOOR KNOBS TO THE ROSES OF THE
SAID KNOBS" to be as follows:-
In many kinds of lock furniture the door knob is fixed in position by being so
connected with the rose that when the latter is fixed by screws to the door the
knob is also secured to the door but is capable of performing the rotary or
angular motion necessary for the withdrawing of the spring bolt or latch of the
door lock.
The contrivances by which the connection of the knob to the rose has heretofore
been effected are for the most part complex and liable to derangement and my
invention consists of the construction and arrangement of parts hereinafter
described whereby the connection of the knob to the rose is effected with great
readiness and with little liability to derangement.
In connecting a door knob to its rose according to my invention I proceed as
follows. I make the end of the neck of the knob of a size suitable to pass through
and work smoothly in the central hole in the rose a shoulder on the neck of the
knob at a short distance from its end limiting the distance to which the neck can
pass through the rose. In that part of the neck of the knob which passes through
the rose I turn a groove passing all round the neck the said groove when the knob
is.in its place in the rose being just within the interior of the rose. I take a flat ring
preferably of thin sheet steel the inner diameter of the said ring being somewhat
less than the diameter of the extreme end of the neck of the knob and somewhat
greater than the diameter of the groove in the said neck. The outer diameter of
the said ring is greater than that of the hole in the rose. This ring is at one part
slit or divided by a radial slit so that the two opposed ends of the divided ring
can be brought into different planes. By placing this divided ring upon the end
of the neck of the knob passed through the hole in the rose and introducing one of
the ends of the said ring into the groove in the neck of the knob the whole of the
ring may by pressure be sprung into the groove. By its elasticity the said ring
closes in the said groove and can only be removed by the application of great

page_text: pressure. The rose and the knob being thus connected but capable of rotating
upon one another the hole in the knob is passed onto the spindle of the lock until
the rose is brought into contact with the door. The rose is then secured to the
door by screws in the ordinary way.
Although I prefer to employ a flat steel ring yet a ring of other material may be
employed. An india rubber ring sprung into the groove in the neck of the knob
will secure the knob to the rose. And although I prefer a ring divided as described
yet two half rings connected by a joint at one pair of their opposed ends may
be employed the ends being fixed after the jointed ring has been introduced into
the groove. Or two detached half rings may be employed the said half rings
being fixed after their introduction into the groove. Or a single half ring may
be empoyed.

Improvements in Connecting Door Knobs to the Roses of the
said Knobs.
I RICHARD GEORGE EVERED of N° 52 Harborne Road, Birmingham in the
County of Warwick, Brassfounder, do hereby declare the nature of my Invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
In many kinds of lock furniture the door knob is fixed in position by being so
connected with the rose that when the latter is fixed by screws to the door the
knob is also secured to the door but is capable of performing the rotary or angular
motion necessary for the withdrawing of the spring bolt or latch of the door lock.
The contrivances by which the connection of the knob to the rose has heretofore
been effected are for the most part complex and liable to derangement and my
invention consists of the construction and arrangement of parts hereinafter
described whereby the connection of the knob to the rose is effected with great
readiness and with little liability to derangement.
In connecting a door knob to its rose according to my invention I proceed as
follows. I make the end of the neck of the knob of a size suitable to pass through
and work smoothly in the central hole in the rose, a shoulder on the neck of the
knob at a short distance from its end limiting the distance to which the neck can
pass through the rose. In that part of the neck of the knob which passes through
the rose I turn a groove passing all round the neck, the said groove when the
knob is in its place in the rose being just within the interior of the rose.
I take
a flat ring, preferably of thin sheet steel, the inner diameter of the said ring being

page_text: somewhat less than the diameter of the extreme end of the neck of the knob and
somewhat greater than the diameter of the groove in the said neck. The outer
diameter of the said ring is greater than that of the hole in the rose. This ring is
at one part slit or divided by a radial slit so that the two opposed ends of the
divided ring can be brought into different planes. By placing this divided ring
upon the end of the neck of the knob passed through the hole in the rose and
introducing one of the ends of the said ring into the groove in the neck of the
knob, the whole of the ring may by pressure be sprung or coiled into the groove.
By its elasticity the said ring closes in the said groove and can only be removed
by force. The rose and the knob being thus connected but capable of rotating upon
one another, the bole in the knob is passed onto the spindle of the lock until the rose
is brought into contact with the door. The rose is then secured to the door by
screws in the ordinary way.
Figure 1 of the accompanying Drawing represents in side elevation partly in
section and Figure 2 in back elevation, a door knob connected to the rose according
to my invention; Figures 3 and. 4 represent the same views as Figures 1 and 2
with the divided ring in the act of being passed to its place in the groove in the
neck of the knob; Figure 5 represents in side elevation and Figure 6 in end
elevation the knob without the rose; Figures 7 and 8 represent my invention as
it may be applied to a knob and rose as an alternative to the mode delineated in
Figures 1 and 2; and Figure 9 represents in front elevation, side elevation and
plan the divided ring which I employ.
The same letters indicate the same parts in the several Figures of the drawing.
a is the knob and 6 the rose; c is the annular groove in the neck of the knob,
the collar d at the front of the said neck having a size suitable to pass through the
central hole in the rose 6 but the enlarged collar d' on the said neck acts as a shoulder
for limiting the distance to which the neck of the knob can pass through the hole
in the rose, the said enlarged collar or shoulder d² seating itself in a recess in the
front of the rose. It will be seen that the annular groove c in the neck of the knob
when the knob is passed into the rose is situated just within the interior of the
rose b; c, e is the flat or nearly flat divided ring of thin sheet steel by the use of
which the knob is connected to the rose while permitting the knob to turn or have
an angular motion in the rose, the two opposed ends of the divided ring being
brought into different planes giving the ring somewhat of a screw like figure (see
Figure 9). The internal diameter of the ring e, e is somewhat greater than the
diameter of the groove c in the neck of the knob and the outer diameter of the
said ring is considerably greater than the diameter of the hole in the rose b.
hole in the ring e, e² may be oval and the opposed ends of the said ring may be
slightly rounded.
The
In attaching the knob a to the rose 6 the neck of the knob is passed into the
rose in the manner represented in the Drawing and one of the ends e of the ring e, e
is introduced into the groove c in the neck of the knob as illustrated in Figures 3
and 4 and by exerting considerable pressure upon the other end e² of the ring and
turning the said ring the whole of the ring is sprung or coiled by a screw like
motion into the groove c in the neck of the knob as illustrated in Figures 1 and 2.
The way in which one end of the ring is first introduced into the groove c and by
the screw like motion described the other part of the ring is also made to enter the
groove will be understood by a comparison of Figures 2, 3 and 4.
By the
elasticity of the ring it closes in the groove c and can only be removed therefrom
by force. The rose and knob b, a are thus connected together, but, the two parts
are capable of rotating upon one another. After the connection of the knob with
the rose, the knob is passed onto the spindle f of the lock or latch in the ordinary
way until the rose is brought against the door when the rose is secured to the door
by screws.
In applying my invention to china or non-metallic knobs and roses, I prefer to
apply a metallic lining g to the interior of the rose as illustrated in Figure 7, the
metallic living being shown separately in Figure 8. By the use of the said

page_text: metallic lining g the knob is prevented from becoming detached from the door in
case the china rose be broken.
Although I prefer to employ a flat or nearly flat steel ring as herein before
described and illustrated yet a ring of other material may be employed. A strong
india rubber ring sprung into the groove c in the neck of the knob will secure the
knob to the rose.
And although I prefer a ring divided as described yet two half
rings connected by a joint at one pair of their opposed ends may be employed, the
ends being fixed after the jointed ring bas been introduced into the groove. Or
two detached half rings may be employed, the said half rings being fixed after
their introduction into the groove. Or a single half ring may be employed.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that what
I claim is;-
Connecting door knobs to the roses of the said knobs by means of the annular
groove c in and the collars d, d' on the neck of the knob in combination with a
flat or nearly flat divided steel ring or an undivided india rubber ring or two
jointed or detached half rings or a single half ring sprung or placed in the said
groove in the neck of the knob after the said neck has been passed into the rose
substantially as herein before described and illustrated in the accompanying
Drawing.
