page_text: Improvements in, or relating to, Door Furniture.
I, CHARLES MACKEY, of the Firm of Bailey and Mackey, of Great Hampton
Row, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to door furniture of that type in which a flanged foot
end of a knob engages and rotates within a semi-circular bracket-seating of a
carrier or rose, which latter is attached to a door, after the affixing screw of
the knob has been turned so as to be covered by the walls of the said seating,
which said type of door furniture is described in the Specification of Letters
Patent granted conjointly to E. V. Bailey and the present applicant No. 12264
of 1887.
The object of my present invention is to simplify the construction of and reduce
the cost of producing such roses or carrier plates.
In carrying out one form of my said invention, I make the rose or bracket
in the form of an elongated plate, adapted to be affixed at the ends to a door
by means of small screws, and having a clearance at the middle to admit of the
passage of the spindle, which is capable of turning therein. Partially surround-
ing this spindle clearance is a pocket or bracket-seating, in the form of an open-
ended and partially-open-fronted socket, wherein and into the grooves or chan-
nels formed by the overhanging or undercut sides, the flange or collar at the foot
of the knob takes and is capable of rotating as a bearing, whilst the neck part
in line with the small affixing-screw hole rests upon the curved bottom of the
said front gap or opening, so that when the knob is turned so as to present this
screw to the bearing edge of the said gap or opening, the said screw is prevented
from backing out or working loose.
In operation, the affixing of the knob and its rose plate to the spindle is
effected by introducing the socket of the plate over the flanged or foot end of
the knob and then threading the knob and rose plate together onto the spindle
end. The rose plate is then turned through about a quarter of a rotation and
the small affixing screw can then be introduced through the small hole thereby
exposed through the neck and into the spindle. Then again bring the rose plate
into its proper position with the small screw being presented to the solid bear-
ing provided for the neck by the curved bottom of the gap in the socket, and is
thereby prevented from coming out, whilst the rose plate is finally secured by
small screws to the door.
I propose to make the rose plate or carrier from cut-out sheet metal and the
blank in this case may consist of a length of metal with a central hole or clear-
ance or side wings, which when folded over nearly onto the front of the plate,
form the socket with the front gap having semi-circular bearing end for the
reception of the neck of the knob, whilst the space within the socket is equal
to the thickness of, or is sufficient to receive the collar of the knob, which is
slid into the said gap in order to take the part of the neck forward or outward
of the foot un to its bearing.

page_text: When my invention is applied to mortice furniture, then propose to employ
a loose and plain spindle and first affix one knob with its rose plate to one end
and pass the spindle through the lock and finally thread over, and secure to the
protruding end, the separable knob and rose plate and affix the latter to the
door by small screws.
I may make the said rose plate with bearing socket from drawn metal of the
same section as the socket to be made, and suitable parts are cut out to form the
spindle clearance and gapped bearing.
I may also make the said rose plate from sheet metal by another method, I
take a cup or hat shaped blank with a middle boss, around which I form a
groove or neck so as to provide a back bearing for the foot flange of the knob.
Then by means of suitable tools, I cut away one half part of the said boss so
as to thereby make a top entrance to the bearing, whilst the front of the remain-
ing half is semi-circularly gapped to form the neck bearing.

I, CHARLES MACKEY, of the Firm of Bailey and Mackey, of Great Hampton
Row, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to door furniture principally of that type in which a
flanged foot end of a knob engages and rotates within a semi-circular bracket-
seating of a carrier or rose, which said rose is attached to a door, after it has
been turned so as to cover the small affixing screw of the knob, which said
type of door furniture is described in the Specification of Letters Patent granted
conjointly to E. V. Bailey and the present applicant No. 12264 of 1887.
The object of my present invention is to simplify the construction of and
reduce the cost of producing such roses or carrier plates.
Figure 1 of the accompanying drawing represents a set of door furniture
fitted or provided with an improved form of rose or carrier plate made from sheet
metal and in accordance with one form of my invention. This view shows the
knob spindle (which is of the Wilkes type) and rose plate in elevation.
Figure 2 represents a longitudinal vertical section of the said furniture, but
with the one knob broken away.
Figure 3 shows the knob with rose plate, and the spindle, also in longitudinal
vertical section, representing how the said knob and rose plate are engaged with
one another before they are introduced onto the end of the spindle.
Figure 4 is a transverse vertical section of Figure 2 upon the dotted line x.
Figure 5 shows the knob in elevation and the rose plate in vertical section,
separated from one another.
Figure 6 represents an edge view and a front elevation of the rose or carrier
plate separately.
Figure 7 is a view of the blank from which the rose or carrier plate is made.
The same letters of reference indicate corresponding parts in the several
figures of the drawing.
In this form of my invention the rose or carrier a is in the form of an elon-

page_text: gated plate a adapted to be affixed at the ends a², to a door 6 by means of
small screws c, and having a clearance a³ at the middle to admit of the passage
of the spindle d, which is capable of turning therein. Partially surrounding
this spindle clearance is a pocket or bracket-seating a, in the form of an open-
ended and partially-open-fronted socket, and into the groove or channel a³,
formed by the overhanging or undercut sides, the flange or collar e¹, at the
foot 2 of the knob e takes and is capable of rotating therein as a bearing,
whilst the part of the neck coming within the plane of the small affixing-screw
hole e, rests upon the curved bottom a of the said front gap or opening a,
so that when the knob is turned so as to present this screw f to the bearing
edge of the said gap or opening, the said screw is prevented from backing out
or working loose.
In operation, the affixing of the knob and its rose plate to the spindle is
effected by introducing the socket of the plate over the flanged or foot end of
the knob (see Figure 3) and then threading the knob and rose plate together
onto the spindle end. The rose plate is then turned through about a quarter
of a rotation and the small affixing screw can then be introduced through the
small hole thereby exposed in the neck and passed into engagement with one
of the countersinks , of the spindle. Then the rose plate is again brought.
into its proper position, with the small screw presented to the solid bearing
provided for the neck by the curved bottom of the gap in the socket, and is
thereby prevented from coming out, whilst the rose plate is finally secured by
small screws to the door.
I propose to make the rose plate or carrier from a cut-out sheet metal blank
Figure 7, which consists of a metal plate h, with a central hole or clear-
ance and opposite side wings 2 which, when folded over nearly onto the
front of the plate, form the socket a', with the front gap having semi-circular
bearing end for the reception of the neck of the knob, whilst the space within
the socket is equal to the thickness of, or is sufficient to receive, the collar of
the knob, which is slid through the open top into the said gap in order to take
the part of the neck forward or outward of the foot, up to its bearing.
When my invention is applied to mortice furniture, then I propose to employ
a loose and plain spindle and first affix one knob with its rose plate to one end
and pass the spindle through the lock and finally thread over and secure to the
protruding end, the separable knob and rose plate and affix the latter to the
door by small screws. Further, I wish it to be understood that I do not con-
fine myself to the employment of Wilkes' spindles as herein described, as spindles
of the screwed or other type may be used in lieu thereof.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
First The improved form of rose or carrier plate for door furniture, com-
prising an attachment plate and an open-ended socket-bearing, gapped at the
front for the reception of the neck of the knob, substantially as herein described,
and also as set forth in the accompanying drawing.
Secondly: A rose or carrier plate for door furniture, made from a sheet
metal blank, such as represented in Figure 7, having side wings which are
turned over the front to form the open-ended and gapped socket-bearing, sub-
stantially as herein described.
