Improvements in or in the Manufacture of Locking or Fastening
Attachments for Securing Knobs to Spindles.
I, JOSEPH TAYLOR, trading as the Acme Ball Castor Company, of 87, Snow
Hill, in the City of Birmingham, Manufacturer, do hereby declare the nature
of this invention to be as follows:- -
This invention relates to locking or fastening attachments for securing door
and other knobs to their spindles and particularly to that class of attachment
means described in the Specification of Letters Patent granted to William Green
and bearing date the 26th day of October 1885, No. 12805 in which a peg, carried
by a spring clip encircling the neck of a knob, is made to take through a hole
in the said neck and to engage with a hole or depression in a plain spindle. In
this form of attachment, the peg or stud is made separate from and attached by
rivetting or otherwise to the clip.
Now one part of my invention consists in making the said peg or stud and
clip integral or in one piece and from sheet steel or other metal.
Thus, in carrying out one form of my invention, I take a blank of sheet steel,
somewhat of a cruciform figure, that is, with band or strip lengths extending
from the opposite sides of a rectangular shaped body part, with the said exten-
sions slit into the said body leaving only a small distance of solid metal between
the band lengths, which are to form the arms or sides of the clip. The edge
portions of the body part are turned down at right angles to the said body and
then fashioned into semi-circular or half pegs with the concavities opposed and
then when the band lengths have been curved into the figure of a clip, the edges
of the half pegs come together and form a complete peg, depending from the
inner periphery of the completed band clip.
According to another form of my invention, I take a blank of suitable sheet
metal with a middle part and band extensions to form the halves of the clip as
before; the middle part is operated upon by dies and pressures or partly by
pressing and partly by drawing through, in order to form the same into a tube
or hollow stud. The superfluous metal surrounding the mouth is then removed
and the band parts bent into a semi-circular figure to form the clip, with a hollow
stud depending inwards from it.
As a further form, I take a length of metal tubing of the same diameter as the
peg or stud to be made and of a length equal to that of the said peg and one half
of the clip part. Then by slitting the tube longitudinally up the middle to the
point at which the peg terminates and opening out and turning back the split
parts semi-circularly and flattening the same-if necessary-into bands, a knob
attachment, with the ends of the arms of the clip nearly meeting, is produced.
As a still further form, the peg or pin may be made at one end of the band
which is turned up to form a circular clip, adapted to embrace the neck of the
knob. Such peg or pin may be formed from a rectangular piece of solid metal
at one end of the band by a drawing through process or it may be formed from a
cruciform-shaped end part of the blank, the three arms of which are troughed
up and then turned up into a cylindrical peg, after which the body of the blank
is bent or fashioned into a clip.
A further method of making this form of fastener is by taking a length of wire,

page_text: one end of which is left solid or of its original section, whilst the other end is
rolled out flat and then fastened to form the band.
In carrying out the second part of my invention relating to the attachment of
the knob to the spindle, the neck of the knob is drilled completely through from
both sides with plain holes, whilst the spindle has a series of plain transverse
holes formed through it to correspond with the aforesaid holes in the neck. The
knob and spindle are connected together by passing through the corresponding
or coincident holes in them, an extended peg or pin carried by a band or like clip
encirclng the neck of the knob, whereby the knob is attached in such a manner
that the connection pin takes an extended bearing through both the holes in the
neck and one of the adjustment holes in the spindle, whilst the latter is rigidly
connected or secured within the eye of the former.
When the pin is made from sheet metal in accordance with the first part of my
invention, one of the joints may be left slightly open and is closed on being
introduced into the coincident holes and thus makes a spring fit.

Improvements in or in the Manufacture of Locking or Fastening
Attachments for Securing Knobs to Spindles.
I, JOSEPH TAYLOR, trading as the Acme Ball Castor Company, of 87, Snow
Hill, in the City of Birmingham, Manufacturer, 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 locking or fastening attachments for securing door
and other knobs to their spindles and particularly to that class of attachment
means described in the Specification of Letters Patent granted to William Green
and bearing date the 26th of October 1885, No. 12805 in which a peg, carried
by a spring clip encircling the neck of a knob, is made to take through a hole
in the said neck and to engage with a hole or depression in a plain spindle.
In this form of attachment, the peg or stud is made separate from and attached
by rivetting or otherwise to the clip.
Now my invention consists in making the said peg or stud and clip integral
or in one piece and from sheet steel or other metal.
Figure 1 of the accompanying drawings represents one form of blank from
which a knob fastener may be produced in accordance with my invention.
Figure 2 is an elevation of the article produced from the said blank.
Figure 3 is a topside plan thereof.
Figure 4 is a sectional view of the fastener upon the dotted line a Figure 3.
Figure 5 is another section, taken upon the dotted line ¹ Figure 4, whilst
Figure 6 represents a transverse section taken upon the dotted line Figure 2.
In carrying out this form of my invention, I take a blank of sheet steel, such
as represented in Figure 1 and which is somewhat of a cruciform figure, that is
with band or strip lengths a¹, (which are to form the arms of the clip) extending
from the opposite sides of a body part a³, and with gaps or slits a³, made at the
junctions of the strip lengths with the said body leaving only a small amount of
solid metal at the parts a³, coming between the band lengths a¹, and the side
extensions a³, of the blank which are turned down at right angles to the said arm
parts a¹, and then fashioned into semi-circular or half pegs (marked b¹, in

page_text: Figures 2 to 6) with the concavities opposed and then when the band lengths
have been curved into the figure of a circular clip as shown in Figures 2 to 6,
the edges of the half pegs came together and form a complete peg b, depending
from the inner periphery of the completed band clip c.
According to another form of my invention, I take a blank of suitable sheet
metal, such as represented in edge view and plan in Figure 7 from the middle
part a, of which opposite arms or bands a¹, extend to form the halves of the clip
as before; the middle part a², is operated upon by dies and pressure or partly
by pressing and partly by drawing through, in order to form the same into a
tube or hollow stud, such as represented in section in Figure 8 and marked b.
The superfluous metal surrounding the mouth is then removed and the band
parts a, turned into a semi-circular figure to form the clip c, with a hollow
stud b, depending inwards from it, thus forming the fastener, which is repre
sented in section in Figure 9 and in plan in Figure 10.
As a further form, I take a length of metal tubing of the same diameter as the
peg or stud to be made and of a length equal to that of the said peg and one half of
the clip part. Then by slitting the tube longitudinally up the middle as repre-
sented in Figure 11, to the point a³, at which the peg b, terminates and opening
out and turning back the split parts a¹, semi-circularly flattening the same, if
necessary, into bands, a knob-fastener attachment with the ends c', of the arms c³,
of the clip c, nearly meeting, as represented in elevation in Figure 12, top plan
in Figure 13 and section in Figure 14, is produced.
Or the fastener may be made from a blank of sheet metal such as is represented
in Figure 15, in which the two arms a¹, to form the clip run side by side in the
same direction from the part a², which is to form the peg.
In making this fastener, which is represented in plan in Figure 16 and in
section upon the dotted line 3, in Figure 17, the part w², is fashioned by suit-
able means into the tubular peg b and then the parts a¹, are curved in opposite
directions to form the branches c, of the clip.
As another modification, the clip may be made from a strip of metal such as
represented in Figure 18, from which parts a² are cut out near the middle and
turned down and fashioned to form the peg b (see Fig. 19) which is thus made in
two semi-circular halves, whilst the metal of the blank itself is curved to form
the circlar band clip c, from the inner side of which the peg depends. In this
construction, as also in those previously described, the peg is of a spring con-
struction and is thus self-retaining within the holes in the knob and spindle into
which it is placed.
As a still further form, the peg or pin may be made at one end of the band
which is turned up to form a circular clip adapted to embrace the neck of the
knob. Such peg or pin 6 may be formed from a rectangular piece of solid
metal a³, at one end of the band a', (see Figure 20) by a drawing-through process.
Figure 21 shows a plan of the blank and Figure 22 is a section thereof after the
peg 6 has been formed whilst Figure 23 is a section of the completed fastener,
which has a single arm comprehending nearly a complete circle. Or the peg
may be formed from a cruciform shaped end part of the blank, three arms of
which are troughed up and then turned up into a cylindrical peg, after which the
third and longer arm of the blank is bent or fashioned into a clip.
Or the fastener may be made from the T-shaped blank represented in
Figure 24, of which the stem a³, is bent at right angles to the head a¹, and then
fashioned into a tubular figure to form the peg b, whilst the arms formed by the
opposite parts of the said head are curved round to form the clip c, as repre-
sented in the two sectional views Figures 25 and 26.
A further method of making this form of fastener is by taking a length of
wire, such as represented in Figure 27 and rolling out a part of it as represented
in Figure 28. The end a², which is left solid or its original section forms the
peg of the completed clip shown in Figure 29, whilst the other rolled out part
is fashioned to form the band c.

page_text: A modification of this last method is to take a length of half-round wire
Figure 30, and roll out the two ends a', Hat, but leaving intact a part a², at the
middle of an extent equal to twice the length of the peg b, to be formed. This
middle part is folded upon itself so as to bring the flat sides together and forms
the peg b, as represented in Figure 32, whilst the flattened ends a', of the blank
are curved in opposite directions to make the arms or branches of the clip c.
According to a still further method of making a knob fastener from a sheet
metal blank in accordance with my invention, I take such a blank as is repre-
sented in Figure 33, in which two end parts a', are united by a narrow neck u²,
and portions a³, coming on either side of the neck and of an extent about equal
to the length of the peg to be formed, are fashioned into a trough or half-round
shape in cross section as represented in Figure 34. The blank is then folded
upon itself about the neck a³, so as to bring together the opposite edges of the
troughed parts and form a hollow peg b, as shown in Figure 35, after which the
flat portions a, are curved in opposite directions to form the circular attachment
clip c, as also shown in Figure 35 and in the sectional view Figure 36.
Having now particularly described and ascertained the nature of my said
