I, ANDREW CASHIN, of Ivy House, Park Road, Sutton Coldfield, in the County of
Warwick, Lock Manufacturer, do hereby declare the nature of this invention to
be as follows:
This invention consists of the herein described improved means for securing door
knobs to door knob roses by which the door knob is fixed to the door. My inven-
tion is applicable more particularly to those door knobs which are used with
mortice locks and rim locks.
In carrying out this invention the rose has as usual a central circular hole in it
and is made to fit on the circular base of the knob which has a shoulder against
which the front of the rose bears. The circular base of the knob projects through
the back of the rose which is recessed and in this projecting part of the circular
base of the knob there is turned or otherwise formed an annular neck or groove
and fitting in this neck or groove I provide a collar or ring of sheet metal or wire
or other suitable substance which is closed into the said neck after the base of the
knob has been inserted in the rose thus effectually securing the knob and rose
together but allowing of the knob turning round freely.
The closing of the collar or washer into the neck in the knob can readily be
done by making the collar split or divided at one part and opened far enough to
pass into the neck and then the ends of the collar are closed together. Or the said
collar may be made of a dished shape so that its central hole will be large enough
to pass over the circular base of the knob into the neck and then when this dished
washer is flattened the central hole will be reduced in diameter and engage in the
neck of the knob as stated above. Or we may use a divided ring of wire in the
said neck to secure the rose to the knob as stated above.
In another arrangement of this invention, which is particularly applicable when
the rose is raised from sheet metal, the rose is made of a dished form projecting
outwardly and the central hole in the rose is made large enough to pass over the
circular base of the knob against the shoulder of the same and then by tools worked
in a press or by other means the said rose is flattened somewhat so that its central
hole will thereby be reduced in diameter and engage in the neck in the knob and
thus the rose will be effectually secured on the knob but allow of the knob turning
round freely therein.

page_text: Improved means for securing Door Knobs to their Roses.
I, ANDREW CASHIN, of Ivy House, Park Road, Sutton Coldfield, in the County of
Warwick, Lock Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention consists of the herein described improved means for securing door
knobs to door knob roses by which the door knob is fixed to the door. My inven-
tion is applicable more particularly to those door knobs which are used with
mortice locks and rim locks.
I will describe my invention' by referring to the accompanying drawings on
which Fig. 1 is a part sectional elevation of a door knob and rose secured together
in accordance with my invention; Fig. 2 is an end view of the same looking
towards the interior of the rose; Fig. 3 is a cross section of the same on line X X
of Fig. 1; Fig. 4 is a separate view of the rose; Fig. 5 is a separate view of the
door knob and Fig. 6 shews the fastening collar or ring of the same; Fig. 7 is a
part sectional elevation and Fig. 8 is an end view of a door knob and rose secured
together in accordance with my invention and illustrating a slightly modified form
of my invention; Fig. 9 shews the fastening ring of Figs. 7 and 8 before being
fixed on to the door knob and Fig. 10 shews the door knob and rose and fastening
ring of Fig. 9 in position ready for securing the fastening ring to the door knob;
Fig. 11 is a sectional elevation of a door knob and rose fastened together in accord-
ance with a further modification of my invention and Fig. 12 shews separately the
fastening ring which is shewn in Fig. 11; Fig. 13 is a part sectional elevation of
a door knob and rose secured together in accordance with a further modification
of my invention and Fig. 14 shews the door knob and rose illustrated by Fig. 13
ready for being fixed together.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
In carrying out this invention the rose A. has as usual a central hole a¹ in it
and is made to fit on to the circular base b¹ of the knob B which has a shoulder ba
against which the front of the rose A bears. The circular base b¹ of the knob B
projects through the back of the rose A which as shewn is recessed and in this
projecting part of the circular base 61 of the knob there is turned or otherwise
formed an annular neck or groove 3 leaving room for the rose between this neck
or groove 63 and the shoulder 62. In this neck or groove 63 I provide a collar or
ring C preferably made of sheet metal (or as hereinafter described the ring C may
be made of wire or other suitable substance) and made large enough in its hole ca
to pass on to the base 61 and is then closed into the said neck 63 after the base b¹
of the knob has been inserted in the rose A thus effectually securing the knob B
and the rose A together as shewn in Figs. 1, 2 and 3, Figs. 7 and 8 and Fig. 11
but allowing of the knob B turning freely in the rose A.
The closing of the collar or washer C into the neck 6 of the knob B can readily
be done by making the collar C split or divided at one part c¹ as shewn in Fig. 6
and opened far enough for the hole to pass over the foot b' of the knob and then
when the collar C is in position the ends of the collar are closed together thereby.
closing and securing the collar round the neck 63 as aforesaid.
Or (see Figs. 7, 8, 9 and 10) the sheet metal collar C may be made of a dished
shape as shewn for instance by Fig. 9 so that its central hole c¹ will be large
enough to pass over the circular base 61 of the knob as far as the neck 63 and then
when this dished washer C has been placed in position as shewn by Fig. 10 the

page_text: washer is flattened as shewn in Fig. 7 and the central hole c¹ will then be reduced
in diameter and engage in the neck 63 of the knob. The washer C is by preference
made with radial slots c³ so as to facilitate the collar being pressed into the flat
shape.
Or (see Figs. 11 and 12) the collar C may be a divided ring of wire which as
shewn in Fig. 12 is made large enough to pass over the foot of the knob and
then is closed into the neck 63 as shewn in Fig. 11 thus securing the knob B and
rose A together.
In another arrangement of this invention (see Figs. 13 and 14) which is particu-
larly applicable when the rose A is raised from sheet metal, the rose is made of a
dished form as shewn in Fig. 14 projecting outwardly and the central hole a¹ in
the rose is made large enough to pass over the circular base 6 of the knob against
the shoulder 62 of the same, as shewn in Fig. 14, and then by tools worked in a
press or by other means the rose A is flattened somewhat so that its central hole a¹
will thereby be reduced in diameter and engage in the neck of the knob Bas
shewn in Fig. 13 and thus the rose will be effectually secured on the knob but so
that the knob can turn freely therein.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
-
1. The herein described improved means for securing a door knob to its rose.
so as to allow the door knob turning in the rose, consisting of a washer or collar
which after being placed round the base of the knob projecting through the back
of the rose is so compressed and reduced in diameter as to engage in a neck or
annular groove formed round the base of the knob, substantially as described.
2. The combination with a door knob having its base formed with a shoulder b³
and a neck 63, of a rose fitting on said base and the divided washer or collar C
which is placed round said base and compressed and reduced in diameter so as to
engage in the neck 63 and thus secure the knob and rose together in the manner
substantially as hereinbefore described and illustrated by Figs. 1, 2, 3 and 11 of
the accompanying drawings.
3. The combination with a door knob having its base formed with a shoulder 62
and a neck of a rose fitting on said base and the dished washer or collar C which
is placed round said base and flattened and compressed and reduced in diameter
so as to engage in the neck 63 and thus secure the knob and rose together all
substantially as herein before described and illustrated by Figs. 7, 8, 9 and 10 of
the accompanying drawings.
4. The combination of a door knob having a circular base formed with a neck
or annular groove and a sheet metal rose which has been raised into a dished form
with its central hole large enough to pass over the circular base of the knob and
has then been flattened and its internal diameter reduced so as to engage with the
said neck and thus be secured to the knob in the manner substantially as herein-
before described and illustrated by Figs. 13 and 14 of the accompanying drawings.
Dated this 21st day of February 1898.
