PROVISIONAL SPECIFICATION.
Improvements in the Means of Stretching Sacking on Metallic
Bedsteads, Cots, and Couches.
I, LEONARD HAWKES BRIERLEY of Essington Works, Sheepcote Street,
Birmingham, in the County of Warwick, Metallic Bedstead Manufacturer, do
hereby declare the nature of this invention to be as follows:-
My invention has reference to those metallic bedsteads, cots and couches on which
cloth (or canvas) sacking is employed, the same being stretched by means of rods
and screws.
In these bedsteads, cots and couches it is usual to stretch or tighten
the sacking by means of screws taking directly into the tightening rods, which
renders it necessary for the latter to he made of solid iron. By means of my
invention the said rods can be constructed of light tube which is somewhat cheaper
and lighter than solid iron and the requisite workmanship is also slightly reduced
in cost.
In carrying out my improvements I attach (preferably by chill-casting) bosses
to the tightening-rod, in each of which bosses a screwed nut is embedded in such a
position that the tightening screw may take into it.
Or I employ a hook or ring (preferably of malleable iron) with a shank and this
shank is so constructed that the tightening screw.may take into.it, while the hook
or ring portion engages with or is fixed to the tightening-rod. Or the hook (or
ring) may be in one piece with the tightening screw and the screwed portion of.this
take into a nut (preferably a cylindrical one with a flanged bead) and, in this case,
when it is desired to tighten the sacking, the nut (instead of the screw) is turned
by means of the usual key.

Improvements in the Means of Stretching Sacking on Metallic
Bedsteads, Cots, and Couches.
LEONARD HAWKES BRIERLEY of the Firm of Brierley & Sons of Essington
Works, Sheepcote Street Birmingham in the County of Warwick, Metallic
Bedstead Manufacturers, 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 those metallic bedsteads, cots and couches on
which cloth (or canvas) sacking is employed, the same being stretched by means
of rods and screws.
In these bedsteads, cots and couches it is usual to attach the cloth (or canvas)
sacking to four rods one at each end and one at each side of the bedstead, cot
or couch and sometimes the sacking is adjusted by means of screws passing
through the angle-iron frame of the bedstead, cot or couch. into all four of the
said rods but more generally into two only, one each at an end and side of the
bedstead, cot or couch. It has been usual hitherto to make all these, rods of solid

page_text: iron but in my invention I construct them of light tube which is somewhat cheaper
and lighter than solid iron and the requisite workmanship in connection with the
two adjusting or tightening rods is also slightly reduced in cost.
In carrying out my improvements with regard to the non-adjusting rods I merely
substitute tube for the solid iron, as being lighter and cheaper, and, with regard to
the tightening rods I construct these also of tube and, according to one method I
attach bosses (preferably by chill-casting) to each of them, in each of which bosses
a screwed nut is embedded in such a position that the tightening screw may take
into it. Or I employ a hook or ring (preferably of malleable iron) with a shank
and this shank is so constructed that the tightening screw may take into it,
while the hook or ring portion engages with or is fixed to the tightening rod.
Or the hook (or ring) may be in one piece with the tightening screw and the
screwed portion of this take into a nut (preferably a cylindrical one with a
flanged head) and, in this case, when it is desired to tighten the sacking, the
nut (instead of the screw) is turned by means of the usual key.
As applied to the non-adjusting rods of the bedstead, cot or couch, my invention
consists merely in the substitution of tube for solid iron.
As regards its application to the adjusting or tightening rods, I will now proceed
to describe it with reference to the accompanying drawings.
In these drawings a represents a portion of one of the said tightening rods to
which the cloth (or canvas) sacking is attached, 6 indicates a portion of the
corresponding angle-iron side or end bar of the bedstead, cot or couch, c represents
one of the screws by means of which the cloth (or canvas) sacking attached to
the tightening rod a has its tension adjusted or regulated, the bead of the said
screw, where required, being indicated at c¹.
It has hitherto been customary to construct the rod a of solid iron and by
the process of forging to make a hole through it, which is afterwards tapped
with a screw thread suitable to take the screw C. In my improvements I
construct the rod a preferably of tube which is somewhat cheaper and lighter
than solid iron. In some cases I divide this rod into parts as shown in Fig. 1
and connect each two consecutive parts by means of a boss d in which is embedded
by the process of casting a nut e suitable for taking the screw c, or as shown in
Fig. 2 I do not divide the rod a but cast on it shaped bosses as d' in which the
nute is embedded in such a position that the screw c may pass clear of the rod.
Or as in Fig. 3 I employ a look for ring g with shank which is so constructed
that the tightening screw c may take into a threaded hole i in it. Side views of
the screw c with alternative forms of the book fare shown in Fig. 4, 5, 6, and 7,
and a side view of the screw c with the ring g is shown in Fig. 8.
Further modifications of my invention are illustrated in Fig. 9, and 10, in which
is shown the hook fmade in one piece with the screw c. The method of tightening
in this case may be either, as in Fig. 9, by means of an ordinary nut k actuated by
the usual key or preferably, as in Fig. 10, by a specially constructed cylindrical
nut which can be revolved by the application of a key to its head m, the other
end n being formed with a screw thread into which the screw c takes. In place of
the hook shown in Fig. 9 and 10, a ring g as shown in Fig. 11 may be employed.
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. In a metallic bedstead, cot or couch in which the cloth (or canvas) sacking is
stetched on four rods, one at each side and one at each end of the bedstead, cot or
couch and adjusted by means of screws taking into two or more of the said rods,
constructing the said rods of tube instead of solid iron.
2. In a metallic bedstead, cot or couch such as is described in Claim 1, forming
on the adjusting or tightening rods bosses in which are provided the requisite
threaded holes for the tightening screws to take into substantially as described aud
-illustrated in Fig. 1 and 2.

page_text: 3. In a metallic bedstead, cot or couch such as is described in Claim 1, forming
the parts necessary for applying the screws to the adjusting or tightening rods
substantially as described and illustrated in Fig. 3, 4, 5, 6, 7, and 8.
4. In a metallic bedstead, cot or couch such as is described in Claim 1, forming
the parts necessary for applying the screws to the adjusting or tightening rods
and to the corresponding side and end bars of the bedstead, cot or couch
substantially as described and illustrated in Fig. 9, 10, and 11.
