Improvements in Door and other Knobs and in the Mounts
for same.
I, THOMAS TAYLOR of Havelock Place Hanley in the County of Stafford, Manu-
facturer, do hereby declare the nature of this invention to be as follows :-
My invention has reference to that class of knobs in which a metallic mount is
secured at the neck or foot end, and through which said end and mount, a spindle
passes and is affixed by a small screw, which takes transversely through the mount and
neck; and my said invention has for its object to so construct the knob, or the foot
end of the knob and its mount, that it can be cheaply produced, and when produced is
as efficient as knobs and mounts produced by a more expensive process commonly
known.
I will describe my invention in connection with a "Mace's Furniture," and I will
first describe the knob without the mount.
I take a non metallic knob of the ordinary kind, but with an extended neck or collar part
of smaller diameter than the neck or foot part, and which said part of reduced diameter
(upon which the front of the cap or mount seats itself) extends beyond the foot part,
so as to form a boss which works within a sunken or recessed part in the rose; and
passing axially up the neck and collar part, is a square spindle hole of the ordinary
kind, but with the front or forward end a little larger in diameter, than the back end,
for the purpose hereinafter described, and which said spindle hole at back end is of
the exact size of the spindle to be used therewith.
The extended neck or collar of the knob is gapped or slotted and wherein a portion
of the metal of the mount is compressed or bulged for preventing the said mount or cap
from rotating or turning round, when connected or secured in position and also for
receiving the thread of small set screw for attaching the mount and knob to the
spindle.
The mount or cap which is raised or fashioned from sheet metal, consists of a sheet
metal or metallic shell of the same conformation as the foot end of the knob, upon
which the mount or cap fits and seats itself. Thus the mount consists of a shell or cap
of two diameters, the one of an internal size suitable to fit upon the reduced foot end

page_text: of the knob, while the other is of an internal size to fit over the part of larger diameter
of the said foot end.
A spindle hole through the front of the mount consists of a square bushed hole
of the exact size of the spindle, and made by drawing or displacing the metal
inwards, so as to form a bushed neck which lies within the front part of the spindle
hole in the knob when the mount is in position.
By carrying the metal inwards in the formation of the spindle hole instead of being
pierced, an extended metallic bearing is thereby produced.
The transverse hole in the smaller diameter of mount through which the small
screw for the affixing of the spindle passes, is formed in a similar manner to the bushed
spindle hole before named; that is, instead of cutting out or piercing a small hole
through the metal neck, the said hole is produced by bulging inwards or thickening
the metal which admits of the inside being wormed so as to take the threads of the
small screw, which is unattainable when the hole is only pierced; and further, the
said hole gives a greater screw hold by being extended as described.
In securing the mount to the foot end of the knob, it is simply placed in position
with the outer or inside edge of the enlarged part, spun or compressed slightly over
the neck, so as to prevent its withdrawal, while a portion of the neck or reduced part,
is bulged into the gapped part of the foot, when the bush hole or short pipe lies within
the spindle hole up the knob, thereby preventing the mount's rotation.
The spindle hole in the mount and the spindle hole up the knob are of the same
internal diameters; so that when a spindle is in position, it lies evenly within the
mount and within the hole up the knob.
Instead of bulging the metal inwards, for producing holes with extended bearing or
screwed surfaces, I form during the process of raising, thickened parts that when
pierced, will admit of being screwed or form an extended bearing as may be desired.
The rose employed is of the kind used with Mace's sets; that is, with a gapped hole
at one part to admit of the small screw being introduced through the neck.
The hole in the mount wherein the foot of the knob works is of the same internal
diameter as the extended part of the cap or mount as described.
My invention is particularly applicable to china, earthenware, glass, wood and other
non-metallic knobs or handles.

Improvements in Door and other Knobs and in the Mounts
for same.
I, THOMAS TAYLOR of Havelock Place Hanley in the County of Stafford Manu-
facturer, do hereby declare the nature of my invention for "IMPROVEMENTS IN DOOR
AND OTHER KNOBS AND IN THE MOUNTS FOR SAME," and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
My invention has reference to that class of knobs in which a metallic mount is
secured at the neck or foot end, and through which said end and mount, a spindle
passes and is affixed by a small screw, which takes transversely through the mount and
neck; and my said invention has for its object to so construct the knob, or the foot
end of the knob and its mount, that it can be cheaply produced, and when produced,
is as efficient as knobs and mounts produced by a more expensive process commonly
known.
I will describe my invention in connection with a "Mace's Furniture," and I will
first describe the knob without the mount.
I take a non-metallic knob of the ordinary kind, but with an extended neck or
collar part of smaller diameter than the neck or foot part, and which said part of
reduced diameter (upon which the front of the cap or mount seats itself) extends
beyond the foot part, so as to form a boss which works within a sunken or recessed
part in the rose; and passing axially up the neck and collar part, is a square spindle
hole of the ordinary kind, but with the front or forward end a little larger in diameter,
than the back end, for the purpose hereinafter described, and which said spindle hole
at back end is of the exact size of the spindle to be used therewith.
The extended neck or collar of the knob is gapped or slotted, and wherein a portion
of the metal of the mount is compressed or bulged, for preventing the said mount or
cap from rotating or turning round, when connected or secured in position, and also
for receiving the thread of small set screw for attaching the mount and knob to the
spindle.
The mount or cap which is raised or fashioned from sheet metal, consists of a
sheet metal or metallic shell of the same conformation as the foot end of the knob,
upon which the mount or cap fits and seats itself. Thus the mount consists of a shell
or cap of two diameters, the one of an internal size, suitable to fit upon the reduced
foot end of the knob, while the other is of an internal size to fit over the part of
larger diameter of the said foot end.
A spindle hole through the front of the mount, consists of a square bushed hole of
the exact size of the spindle, and made by drawing or displacing the metal inwards, so
as to form a bushed neck, which lies within the front part of the spindle hole in the
knob when the mount is in position.
By carrying the metal inwards in the formation of the spindle hole instead of being
pierced, an extended metallic bearing is thereby produced.
The transverse hole in the smaller diameter of mount, through which the small
screw for the affixing of the spindle passes, is formed in a similar manner to the bushed
spindle hole before named; that is, instead of cutting out or piercing a small hole

page_text: through the metal neck, the said hole is produced by bulging inwards or thickening
the metal, which admits of the inside being wormed so as to take the threads of the
small screw, which is unattainable when the hole is only pierced; and further, the said
hole gives a greater screw hold by being extended as described.
In securing the mount to the foot end of the knob, it is simply placed in position with
the outer or inside edge of the enlarged part, spun or compressed tightly over the
neck, so as to prevent its withdrawal, while a portion of the neck or reduced part, is
bulged into the gapped part of the foot, when the bush hole or short pipe lies within
the spindle hole up the knob, thereby preventing the mount's rotation.
The spindle hole in the mount, and the spindle hole up the knob are of the same
internal diameters; so that when a spindle is in position, it lies evenly within the
mount and within the hole up the knob.
Instead of bulging the metal inwards, for producing holes with extended bearing or
screwed surfaces, I form during the process of raising, snug parts that when pierced,
will admit of being screwed, or form an extended bearing as may be desired.
The rose employed is of the kind used with Mace's sets, that is, with a gapped hole
at one part to admit of the small screw being introduced through the neck.
The hole in the mount wherein the foot of the knob works, is of the same internal
diameter as the extended part of the cap or mount as described.
My invention is particularly applicable to china, earthenware, glass, wood and other
non-metallic knobs or handles.
I will now proceed to describe with reference to the accompanying Drawing, the
manner in which the same is to be performed.
Figure 1 represents in plan, and figure 2 a longitudinal vertical section of a knob
and mount made according to my invention. Figure 3 is a transverse section of the
said knob upon the dotted lines A B figure 1.
Figure 4 is an end elevation (foot end) of the knob without the mount. Figure 5
is an inside end elevation of the mount. Figure 6 represents sections of the part
separately, and figure 7 is another form of mount without an extended spindle bearing.
Figure 8 shows the blank from which the mount is raised or fashioned.
The same letters of reference indicate corresponding parts in the several figures of
the Drawing.
a is the knob, a² is the foot end of the knob, and a³ is a recessed or gapped part,
wherein the hanging or depending inside screw hole part 63 of the neck b² of the mount b
fits, for preventing the said mount from rotating or turning round, when connected or
secured in position upon the foot end, and through which said thickened metal or
hanging pipe or lug part of the mount, a small screw pin c passes, for securing the
knob to the spindle d.
The mount has also an extended spindle bearing surface 6 produced by the bulging
and forcing inwards of the metal of the mount, during the process of shaping. The
outside of this extending spindle bearing, fits within a corresponding recess formed in
the spindle hole at of the knob.
In the case of the mount figure 7, the hole in the knob is of the exact section as the
spindle, or of the size of the piercing or hole 6 in the mount.
The mount or cap b, which is raised or fashioned from the blank figure 8, consists
of a shell of two diameters, with an inside screw-hole pipe or lug 63, and an extended
spindle bearing 6, produced or formed during the process of raising or shaping; that
is to say, the hanging screw hole pipe or lug 63 is formed from metal distended at that
part during the process of shaping, by leaving recesses or corresponding hollows in the
tools employed, and wherein the metal flows on the raising and shaping of the mount.
The extended spindle bearing 6, is made by the partial bulging inwards and displace-
ment and distension of metal, during the said process of shaping.
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. Making or forming with the shells of sheet metal mounts or caps, for door
and other knobs, an inside raised or hanging screw hole pipe or hollow lug b³, (which

page_text: latter is by a subsequent process, drilled, bulged or sunken) through which a wormed
pin screws and passes, for affixing a knob to a spindle, substantially as described and
set forth.
Secondly. Making and providing sheet metal mounts, with inside spindle bearing
bushes 6', produced either by the process of bulging inwards, or distending the metal
in cut away parts of the tools employed in the process or processes of raising or
shaping.
Thirdly. In door and other knobs. Making or forming in the foot, or in the front
of the neck part of a knob, a gap or opening, (proceeding from the outside to the
spindle hole) wherein a depending or inside standing out screw-hole lug or pipe fits
and passes in a direction to the spindle hole, substantially as and for the
herein
described and set forth.
purpose.
