PROVISIONAL SPECIFICATION.
Improved Means for Fixing Castors to Metallic Bedsteads and other
Articles of Furniture.
I, LEONARD HAWKES BRIERLEY of Sheepcote Street, Birmingham, metallic
bedstead manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
My invention has reference to the fixing of the castors to the pillars of metallic
bedsteads and to other articles of furniture to which castors are used, by means of a
nut and a correspondingly screwed castor-peg, to effect which I construct the several
parts as follows;
A nut is either embedded in, or fixed on to, the cast-iron piece at the foot of the
pillar (in the case of a metallic bedstead), and the castor-peg (which is attached
immovably to the castor) is constructed with a screw-thread on a short portion of its
length. In fixing the castor, this portion is screwed right through the nut into a cavity
of a slightly larger diameter, previously formed to receive it, and, at the same time
an unscrewed portion of the peg occupies the hole in the nut. By this means the
castor (with peg) can be taken off or put on the pillar with great facility, and, when
in position, is free to revolve in its socket, and will not come off unless it be
intentionally unscrewed.
In case it is preferred to have the castor-peg fixed to the pillar-and, of course,
separate from the castor-the nut would then be inserted in, or attached to, the
body of the castor; or the nut could be discarded, providing that a portion of the
hole in the castor were tapped to fit the screwed portion of the peg.
The castors may be fixed to the pillars after the bedstoad itself is fitted up and
thus all risk, of breakage is avoided.
Although have only described my invention as applied to the pillars of a
metallic bedstead, it is evident that it is applicable to any description of furniture to
which castors are used.

COMPLETE SPECIFICATION.
Improved Means for Fixing Castors to Metallic Bedsteads and other
Articles of Furniture.
I LEONARD HAWKES BRIERLEY of Essington Works, Sheepcote Street Birming-
ham, in the county of Warwick, Metallic Bedstead 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 has reference to the fixing of the castors to the pillars of metallic
bedsteads and to other articles of furniture to which castors are used, by means of a
nut and a correspondingly screwed castor-peg, to effect which I construct the several
parts as follows:
A nut is either embedded in, or fixed on, to the cast-iron piece at the foot of the
pillar, (in the case of a metallic bedstead) & the castor peg (which is attached
immovably to the castor), is constructed with a screw thread on a short portion of its
length. In fixing the castor, this portion is screwed right through the nut into a
cavity of a slightly larger diameter previously formed to receive it, and, at the same
time an unscrewed portion of the peg occupies the hole in the nut.
By this means the castor (with peg) can be taken off or put on the pillar with
great facility, and, when in position, is free to revolve in its socket and will not come
off unless it be intentionally unscrewed.

page_text: In case it is preferred to have the castor-peg fixed to the pillar-and, of course,
separate from the castor,-the nut would then be inserted in, or attached to, the body
of the castor; or, the nut could be discarded, providing that a portion of the hole
in the castor. were tapped to fit the screwed portion of the peg.
The castors may be fixed to the pillars after the bedstead itself is fitted up and
thus all risk of breakage is avoided.
I will now describe my invention, as applicable to metallic bedsteads, by referring to
the annexed drawings.
Figures Nos. 1 to 5 inclusive relate to cases in which the castor and peg are in
one piece. Figures Nos. 6 to 13 inclusive are intended to illustrate those cases in
which the castor-peg is permanently fixed to the foot of the bedstead-pillar.
No. 1 shows the lower part of the leg or foot of a metallic bedstead-pillar arranged
to receive the castor No. 2, both being constructed according to my invention.
In No. 1, a is the tube of the pillar, b, the screwed nut, c the screwed hole in the
same, d the cap requisite to form the cavity e, f is the cast iron portion of the pillar
arranged with a hole g. In No. 2, h is the body of the castor, i the peg of which jis
a short screwed portion. In fixing the castor in accordance with my method, the
pegi is inserted in the holo g and the threaded portion j is screwed completely through
the correspondingly threaded hole c in the nut b, so as to occupy the cavity e.
castor is by this means secured sufficiently firmly in its position, is free to revolve and
will not come out of place unless it is intentionally unscrewed.
The
Nos. 3, 4 & 5 show a modification of the precoding method in which the screwed
portion of the peg i is near the body of the castor. In No. 3 the nut 6 is fixed
to the foot of the pillar by means of rivets. In No. 4 the nut is cast in the foot
of the pillar; to form the cavity e a sand-core is required, or it may be made by means
of a separate cap as d in No. 1.
No. 6 shows the foot of a pillar in the lower part of which the castor-peg i is cast,
the latter having the screwed portion near the base of the pillar. No. 7 represents
a castor suitable for fixing on the foot shown in No. 6; in this the nut is riveted on
to the upper part of the body h of the castor. In No. 8 the nut b is cast into
the upper part of the body of the castor, and, in No. 9 the nut is omitted and the
upper portion of the hole in the body of the castor is made smaller than usual and
tapped with a screw thread to suit the throad j in No. 6. No. 10 is a modification
of No. 6, the screwed portion ; being near the point of the peg i. No. 11 illustrates
a castor suitable for fixing on the foot shown in No. 10, the nut & being rivetted to
the lower part of the body h of the castor.
In No. 12 the body h of the castor has the nut cast in, as No. 8, but in its lower
portion. In No. 13 the nut is omitted and the hole in the body of the castor is
screwed at its lower extremity. The hole g in Nos. 8 & 9 may be formed either by using
a sand-core or by casting in the body ha cap as d in No. 1 but of a shape suited to
receive the castor-peg i.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. Fixing castors to the pillars of metallic bedsteads and other articles of furniture
by means of a castor-peg having a short portion of its length screwed, in conjunction
either with a nut correspondingly screwed, or, with a castor in the body of which the
hole is, for a short distance, correspondingly screwed, substantially as described and
illustrated.
2. Forming, for the purpose of fixing a castor to the foot of a pillar of a metallic
bedstead or other article of metallic furniture, a cavity, either in the said foot, or in
the said castor, by means of a separate cap, an example of which is illustrated by d
figure No. 1.
