The
This invention has reference to metallic terminal knobs or ornaments which
are used on metallic and other bedsteads fenders cornice poles curtain rods and
other articles. The said terminal knobs or ornaments are usually made with a
screw threaded central hole in the foot or neck to screw on to a fixing screw.
better kinds of terminal knobs or ornaments are made with a cast metal neck
and foot in which the screw threaded hole is formed but the cheaper kinds are
made with a stamped sheet metal neck and foot which is punched inwardly round
the central hole and in this part the screw thread is formed but owing to the
metal being thin this screw threaded part of the foot is liable to break away.
Sometimes the said terminal ornaments have been provided with a round nut
or washer in the interior for the fixing screw to engage with but such nut or
washer is liable to turn round in the sheet metal neck or foot and when this
happens the terminal knob or ornament cannot be properly fixed in place or
if so fixed it cannot readily be removed.
By my invention I so construct the sheet metal neck and foot of the terminal
knob or ornament that a perfectly sound screw thread is provided in it for the
fixing screw so that the terminal knob or ornament when fixed in place is as
secure as is one of those terminals knobs or ornaments which is made with a
cast neck and foot.
In carrying out my invention 1 provide and fix, as hereinafter described in
the sheet metal neck or foot of the terminal knob or ornament a nut which is
of square or polygonal or other shape than a true circle and this nut is made of
such a size as to fit in the base of the sheet metal neck with the angles
of the nut bearing hard against the interior of the foot. After the nut has been
thus placed in position the neck is rolled or swaged inwardly and reduced in
diameter immediately above the foot thereby effectually preventing the nut from
turning round in the foot or from coming out of the same. The spaces between
the flats of the nut and the interior of the neck may if desired be filled up with
lead or other suitable substance. In order to more effectually prevent the nut
from turning round in the foot of the knob or terminal ornament the latter is or
may be made with a sunk or raised face corresponding with the face of the nut
and in which face the nut fits.
According to a modification of my invention I employ a round or approximately
round nut in the manner above. described but this nut is serrated or notched all
round or partly round its circumference so that when placed in position in the
hollow sheet metal neck as above described and the neck is swaged rolled or other-
wise reduced in diameter immediately above the foot the metal of the neck will

effectually prevented from turning round or becoming loose in the foot.

improvements in Metallic Terminal Knobs or Ornaments.
I, Thomas BessaNT, of Stour Works, Hockley Street, in the City of Birmingham
Brass Worker, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The
This invention has reference to metallic terminal knobs or ornaments which
are used on metallic and other bedsteads fenders cornice poles curtain rods and
other articles. The said terminal knobs or ornaments are usually made with a
screw threaded central hole in the foot or neck to screw on to a fixing screw.
better kinds of terminal knobs or ornaments are made with a cast metal neck
and foot in which the screw threaded hole is formed but the cheaper kinds are
made with a stamped sheet metal neck and foot which is punched inwardly round
the central hole and in this part the screw thread is formed but owing to the
metal being thin this screw threaded part of the foot is liable to break away.
Sometimes the said terminal ornaments have been provided with a round nut
or washer in the interior for the fixing screw to engage with but such nut or
washer is liable to turn round in the sheet metal neck or foot and when this
happens the terminal knob or ornament cannot be properly fixed in place or
if so fixed it cannot readily be removed.
By my invention I so construct the sheet metal neck and foot of the terminal
knob or ornament that a perfectly sound screw thread is provided in it for the
fixing screw so that the terminal knob or ornament when fixed in place is as
secure as is one of those terminals knobs or ornaments which is made with a
cast neck and foot.
I will describe my invention by referring to the accompanying drawing on
which Fig. 1 is an inverted plan of a metallic terminal ornament or knob made
in accordance with this invention; Fig. 2 is a sectional elevation of the same on
line Y Y of Fig. 1; Fig. 3 is a sectional elevation of the lower part of the same on
line X X of Fig. 1; Fig. 4 shows the nut part of the same separately; Fig. 5
is a sectional elevation and sectional plan of the foot part of the said knob or
terminal ornament ready to receive the nut; Fig. 6 shews the nut in position in
the said foot part of the terminal knob or ornament ready for the latter to be rolled
or swaged inwardly around the nut to secure the same in place; and Fig. 7
illustrates a modified form of the said nut.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawing.
A¹ is the foot of the knob or terminal ornament, A2 is the lower part of the
boly of the same and A³ is the upper part of the said body.
In carrying out my invention I provide and fix, in the manner hereinafter 4
described, in the sheet metal foot A¹ of the terminal knob or ornament a nut B
which is made of a square shape as shewn in Figs. 1, 4 and 6 (or this nut may be
of polygonal or other shape than a true circle. This nut B is made of such a
size as to fit in the hollow foot A¹ before the latter has been rolled or swaged
inwardly at a to form the neck. The base al of the foot A¹ has a sunk or raised 5

page_text: face corresponding with the face of the nut B, that is to say, there are four sinkings
forming projections a3 a4 a5 a6 on the inside of the base forming between them
a square recess in which the face of the nut fits to prevent the nut from turning
in the foot.
After the nut B has been placed in position within the hollow foot A¹, as shewn
in Fig. 6 and by the dotted lines in the plan view of Fig. 5, that is before the
upper part A of the body has been fixed to the lower part A2, the neck or foot A¹
is rolled or swaged inwardly at a² and reduced in diameter immediately above
the nut B and on the top of the nut B as shewn at Figs. 2 and 3 thus effectually
preventing the nut B from turning round in the foot A¹ or from coming out of
the same.
The spaces c between the interior of the foot A' and the sides of the nut B
may if desired be filled up with lead or other suitable substance, although I do
not find that such filling up is necessary for the securing of the nut.
According to a modification of my invention I employ a round or approximately
round nut 1 (such for instance as shewn by Fig. 7) in the manner above described
but this nut D is serrated or notched at d¹ all round or partly round its circum-
ference so that when placed in position in the hollow sheet metal foot A¹ as above
described and the neck is swaged or rolled or otherwise reduced in diameter
immediately above the nut D the metal of the neck will be pressed into the
serrations or notches of the nut and thus the latter will be effectually prevented
from turning round or becoming loose in the foot.
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:-
A sheet metal terminal knob or ornament having a fixing nut of square or
other shape than round secured in its hollow base or foot by the nut fitting
in a corresponding sinking in said foot in combination with the neck being rolled
or swaged down at a² to grip the nut all substantially as set forth.
