PROVISIONAL SPECIFICATION.
Improvements in Bedstead Rail and like Knobs and Balls.
I, WILLIAM HENRY BAGLEY, of Viaduct Works, Aston, in the County of
Warwick, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the mode of attaching knobs for bedsteads and like
purposes to the metal screws or screw pins required for their use and my object is
to so modify the screw and the manner of its insertion into and connection with the
knob that the said sorow may be so firmly attached to the knob that it remains
firm and doos not become loose or allow the knob to turn round independently
when being screwed into place. At the same time my object is to so arrange the
mode of manufacture that a very cheap and readily manufactured article is
produced.
"
In carrying my invention into effect I draw a brass or other metal cup in the
usual manner and 1 form the end of the screw pin to be inserted into and attached
to the knob, to a broad palm or flat. This 1 preferably do by beating out the end
of a continuously screwed piece so that the screw produces on the flattened part
serrated edges. Near the broad flattened part I flatten the screw slightly on both
sides. 1 insert the broad at end of the screw into the open cup and then close in
the metal to form a knob in the usual manner. The broad flattened part of the
screw inserted into the knob is so proportioned that in the closing in process the
interior of the metal knob is firmly forced on the four external corners or serrations
of the inserted flat and the edge of the aperture of the knob or ball is firmly closed
on the smaller flats at the base of the screw.
In this mannor I firmly hold the ball or knob on the end of the screw pin by the
firm grip of the metal of the said knob on the edges of the inserted flat and I
prevent the knob from turning by the smaller flattened part of the scrow at the
base of the screwed pin where the metal of the aperture of the knob is forced on
the said flats.
Although I prefer to flatten the end of a screw cut off from a continuous length
of screwed rod or a long screwed rod, because of the greater economy of manu-
facture yet I may form sorewed studs having suitably forged ends with sharp
corners and convenient flats to seize the interior metal of the knob and prevent it
from turning round. Such forged ends may be variously shaped so long as sharp
edges are formed on which to close in the metal of the knob.
Dated this 6th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Bedstead Rail and like Knobs and Balls.
I, WILLIAM HENRY BAGLEY, of Viaduct Works, Aston, in the County of
Warwick, Manufacturer, 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 :—
My invention relates to the mode of attaching knobs for bedsteads and liko
purposes to the metal screws or screw pins required for their use, and my object is

page_text: to so modify the screw and the manner of its insertion into and connection with the
knob that the said screw may be so firmly attached to the knob that it remains
firm and does not become loose or allow the knob to turn round independently
when being screwed into place. At the same time my object is to so arrange the
mode of manufacture that a very cheap and readily manufactured article is
produced.
In the accompanying sheet of explanatory drawings,
Figure 1 is an elevation of an ordinary parallel metal screw pin to which a knob
or head is to be attached.
Figure 2 is an elevation showing the end of the screw pin flattened or enlarged 1
and Figure 3 is a side cloration of the same previous to the attachment of the
knob.
Figure 4 is a sectional elevation of the screw with the knob attached.
Figure 5 is an elevation and Figure 6 is a sectional plan of the same.
In carrying my invention into effect I draw a brass or other metal cup A in the 1
usual manner, and I form the end of the screw pin B to ho inserted into and
attached to the knob, to a broad palm or flut b. This I preferably do by beating
out the end of a continuously screwed piece B so that the screw produces on the
flattened part serrated edges c. Near the broad flattened part I Hatten the screw
slightly or both sides. I insert the broad fint end of the screw into the open cup A :
and then close in the metal to form a knob in the usual manner. The broad
flattened part of the screw inserted into the knob is so proportioned that in the
closing in process the interior of the metal knob is firmly forced on the four
external corners or serrations C C C C of the inserted flat b, and the edge of the
aperture of the knob or ball is firmly closed on the smaller flats at the base of the
screw.
b
In this manner I firmly hold the ball or knob on the end of the screw pin by
the firm grip of the metal of the said knob on the edges of the inserted flat and I
prevent the knob from turning by the smaller flattened part of the screw at the
base of the screwed pin where the metal of the aperture of the knob is forced on 3
the said flats.
Although I prefer to flatten the end of a screw cut off from a continuous length
of screwed rod, or a long screwed rod because of the greater economy of manu-
facture yet I may form screwed studs having suitably forged ends with sharp
corners and convenient flats to seize the interior metal of the knob and prevent it 3
from turning round.
Such forged ends may be variously shaped so long as sharp edges are formed on
which to close in the metal of the knob.
Having now particularly described and ascertained the naturo of my said inven-
tion, and in what manner the samo is to be performed, I declare that what I
claim is :-
In a mounted knob or ball for use upon bedstead rails and for other purposes, the
method of attaching and securing such ball or knob to a pin or screw by Hattening
down the end of such pin or screw, substantially as and for the purposes horein-
before described and as illustrated in the accompanying drawings.
