Improvements in and connected with Metallic Bedsteads.
I, JOHN THOMAS PETFORD, of the Standard Bedstead Works, School Brow,
Warrington, in the County of Lancaster, Manager, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the manufacture of tops and bottoms for bedstead
posts, the flowers or chills on bedsteads, and the like, and its object is to simplify
and cheapen their construction.
As at present commonly manufactured, a bedstead post top consists of a suitable
casting with which is incorporated a suitable and separately screwed stem upon
which the vase or knob is adapted to be screwed.
According to these improvements the top or bottom is cast in a chill or the
like the interior of which is formed with a screw thread so that at one operation
the casting is completed with a thread for the reception of the vase or knob. The
thread in the vase is preferably formed by spinning, pressing, or the like. Rails
may be combined with the tops and bottoms in the same manner as at present
usual, that is their ends may be fitted or combined with rings or their equivalents
which fit upon the castings and are held in place by the vases or knobs.
The chills or flowers of bedsteads may be similarly cast with a screw thread.
It is preferred to form the tops and bottoms in such a manner that they enter
into and are adapted to the shape of the vases so as to support them and prevent
them being dinged or crushed.
In the case of a bottom constructed with these improvements it is preferred
to form or cast a seat for a ball upon its lower face. The vase or cap is then
provided with a hole through which the ball can protrude to a certain extent
but through which it cannot pass, so that when the cap is screwed in place the
ball is held loosely upon its seat and acts as a castor.

Improvements in and connected with Metallic Bedsteads.
I, JOHN THOMAS PETFORD, of Haigh Foundry, Wigan, in the County of Lan-
caster, Bedstead Manufacturer, late of the Standard Bedstead Works, School Brow,
Warrington, also in the County of Lancaster, 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:-
This invention relates to the tops and bottoms of bedstead posts, the flowers

page_text: and chills on bedsteads, and similar parts which are adapted to receive vases,
caps or the like, and its object is to simplify and cheapen their construction and
to render them more durable.
Such parts, as at present commonly manufactured, consist of a suitable casting
with which is incorporated a suitable and separately screwed stem upon which the
vase, knob or the like is adapted to be screwed.
According to these improvements the top or bottom or similar part is cast in
a chill or the like the interior of which is formed with a screw thread so that
at one operation the casting is completed with a thread for the reception of the
vase or knob. The thread in the vase may be formed by, pressing, spinning or
similar operation, or in any other well known way. Rails may be combined with
the tops and bottoms in the same manner as is at present usual, that is their ends
may be carried in rings or their equivalents which fit upon the castings and are
held in place by the vases, knobs or caps.
The tops, bottoms, chills or flowers, may be formed in such a manner that
they enter into and are adapted to the shape of the vases or caps so as to support
them and prevent them from being dinged or crushed.
In the case of a bedstead post bottom constructed with these improvements a
seat for a ball may be cast upon the lower face. The cap is so formed that a ball
placed within the seat protrudes partly through it and is loosely held so that it
may act as a castor.
The accompanying drawings illustrate how these improvements may be carried
into effect.
Figure 1 is a representation in elevation of a bedstead post top fitted with a
vase or cap, this cap being shown partly in elevation and partly in section. The
top A is cast in a chill in the usual manner but the interior of the chill is addition-
ally provided or formed with a screw thread so arranged and disposed that the
casting when removed from the mould has a screw thread B formed upon it.
Upon this screw thread is placed the vase or cap C, which may have a corre-
sponding screw thread formed in it in any suitable manner or by any suitable
means, as, for example, by pressing or spinning. A separate screwed stem for
the vase is thus dispensed with.
Figure 2 illustrates a bedstead post bottom D which is similarly cast in a chill
with a screw thread B. The cap E may be formed to rest directly upon the floor,
or may have attached to it a castor of the usual construction, or, as shown, it
may hold loosely in place within the seat or recess F a ball G which acts as a
castor. The seat or recess when employed would be cast at the same time as the
screw thread.
Figure 3 shows in elevation an ordinary chill or flower H upon a metallic bed-
stead, this chill or flower being similarly provided with a cast screw thread B
as herein before described to receive the cap J.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:―
1. A bedstead post top or bottom which is cast in a chill mould the interior
of which is provided with a screw thread in such a manner that a screw thread for the
reception of a cap or the like is cast upon the top or bottom, substantially as
hereinbefore described and as illustrated by Figures 1 and 2 of the accompanying
drawings.
2. A chill or flower for metallic bedsteads cast in a chill mould the interior
of which is formed with a screw thread in such a manner that a screw thread
for the reception of a cap or the like is cast upon the chill or flower, substantially
as herein before described and as illustrated by Figure 3 of the accompanying
drawings.
3. A bedstead post bottom which is cast in a chill mould the interior of which

page_text: is so formed that a screw thread and a seat for a ball are cast upon the bottom,
substantially as hereinbefore described and as illustrated by Figure 2 of the
accompanying drawings.
