We SAMUEL BOTT of 4 Bloomsbury Street, Birmingham, and CHARLES HOMER, of
88 Vauxhall Road Birmingham, both in the county of Warwick Manufacturers do
hereby declare the nature of this invention to be as follows :-
This invention relates to the construction of castors for furniture, bedsteads, and
other purposes, and has for its object the construction of the part of such castors
known as the "horns" or bracket of wrought metal. In castors hitherto in use there
is a great difficulty and inconvenience owing to the continual breakage of these parts
by reason of their being made of cast metal; particularly so is it the case with castors
attached to metallic bedsteads and furniture of the common and medium class, and
even so very often upon the better class of goods, but in this our invention, such
breakages cannot occur.
A castor bracket or "horns," (that is the part of the castor which receives the
roller, and which itself is made to swivel or rotate upon a fixed pin, pivot, or its
equivalent) made according to this our invention, may be described somewhat as
follows:-Assuming that it is constructed of wrought iron and of a flat strip
section. We should take the strip and having cut therefrom a required length,
we should trim and shape the ends to form the extremity of the horns, piercing
therein holes. for the reception of the axle pin. The piece of metal would then
be folded nearly double, somewhat of a U shape. The width of the extreme
ends is arranged to suit the thickness of the roller, while near the doubled or
half round end, it is nipped in, or shaped by suitable tools to fit the fixed pin or pivot,
upon which it is to swivel or rotate. At such parts where it is thus nipped in, or
closed, there may if necessary be put a rivet, but generally it would not be required.
Instead of forming the eye or socket for the fixed pivot, directly from the metal
forming the horns, we may if desirable form a separate "eye" or socket, and then
close the metal forming the horns upon and around it.

page_text: The section of metal out of which these "horns" or brackets would be made may be
varied, as for instance, they may be out of plain sheet metal, or any particular rolled
section.
The shape of these horns also may be varied to suit taste, or facility of manufacture,
as, that they may be cut out of the metal the necessary shape ready for folding into the
finished form, or, out of strip, and then folded and bent as may be necessary.
دو
These "horns when made of inferior metal, may be covered with thin sheet metal,
or they may be bronzed, coppered, Japanned, or otherwise ornamented.

Improvements in the Construction of Castors for Furniture,
Bedsteads, and other Purposes.
We SAMUEL BOTT of 4 Bloomsbury Street, Birmingham and CHARLES HOMER of
88 Vauxhall Road, Birmingham both in the county of Warwick, 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:
This invention relates to the construction of castors for furniture, bedsteads, and
other purposes, and has for its object, the construction of the part of such castors known
as the "horns or bracket of wrought metal in the manner as hereinafter set forth.
"
In castors hitherto in use, the horns of which are constructed of cast metal, there is
a great difficulty and inconvenience owing to the continual breaking of these parts by
reason of their being made of such cast metal, and particularly so is it the case with
castors attached to metallic bedsteads, and furniture of the common and medium class,
and even so very often upon the better class of goods, but in this our invention such
breakages it may be said cannot occur.
A castor bracket or "horns" (that is the part of the caster which receives the roller,
and which itself is made to swivel or rotate upon a fixed pin, pivot, or its equivalent)
made according to this our invention may be described somewhat as follows, having
reference to the accompanying illustrative sheet of drawings upon which are figures and
letters of reference.
Fig. 1 is a view of a strip of metal from which our improved caster "horn" or
bracket may be made, a, being a section of the same, and b a side elevation.
Fig. 2 is a piece, or length cut from the strip of a suitable length to form the said
bracket, after the manner of the following processes.
Generally, we should provide a punch and bottom die similar in shape to Fig. 2,
but inasmuch as the strip would be prepared (generally) of the required width, the
cutting out action of the tools, would thus be lessened, operating only upon the ends
of such piece.
We then take the piece (Fig. 1) and preferably in a press or similar tool fold it into
the shape of Fig. 3; then further close it around a peg, by suitable tools, into the
shape Fig. 4, the said peg being situated at c.
We now place the form Fig. 4, in a bottom tool, which holds it in position, while a
top tool descends, and ", opens out," or "tapers," or "cups" the part d, as shewn in
Fig. 5. This piece is then firmly held about the cup part in a die or grip, while the
end e is bent as shewn in Fig. 6. We then further secure it in a die about the
cup
part similar as before, and divide or open out the ends and press them into shape
similar as shewn in plan in Fig. 7. We find it an advantage both in the manipulation
of the metal and also in the wear and tear of the tools, to perform or complete this
shape Fig. 7 by two operations, that is, pass them through the same or similar tools a

page_text: second time, in order to more prefectly ensure their interchangeable or exact similar
form.
The piercing, or drilling, or punching, of the holes g, to receive the axle of the
roller h, may now be done.
We now, in most cases, place the bracket Fig. 7 into a bottom die of suitable form,
to well support it all around, and then bring down upon it with considerable pressure,
a top tool which further countersinks the cup part at i, and also throws over the metal
from the upper outer edge at j, giving it an appearance in plan, of a stronger section
than as shewn in Fig. 1. The roller h, may now be inserted between the ends f, the
axle pin inserted, and rivetted over at each end, when the bracket would be
completed.
In fig. 10 we have shewn how our invention may be applied to the pillar of a
metallic bedstead, the said fig. 10 being a section of Fig. upon line A B, with the
It will be readily seen that the fixed pin or pivot 1, may be attached to any form
of connection, such as a plate, or socket, or screw, whereby it may be secured to any
article of furniture &c.
part of pillar k, and swivel pivot or fixed pin added thereto.
If necessary we may make the part at m Fig. 7, sufficiently long to admit of a rivet,
to tie the two parts together at that point, generally however this would be
unnecessary.
Instead of forming the eye or socket, that is the cupped part d, i, i Figs. 5, & 8
directly from the strip as shewn, we may in some instances, form a separate eye of cast
metal, and then close the metal forming the horns upon and around it, similarly as
shewn in Fig. 11, so that in plan, the strip around the "eye" would appear similar to
that of Fig. 7.
The section of metal from which these "horns" or brackets may be made, may be
varied, as they may be made from plain sheet metal, or any particular rolled section,
generally the latter.
"
These "horns may be coppered, bronzed, Japanned, or otherwise ornamented to
suit requirement.
Having now particularly described and ascertained the nature of this our said
invention and the manner in which it is to be performed, we declare that what we
claim as our invention is :-
*
"
1st. The making of caster "horns' or brackets from a piece of parallel metal or
strip by bending and shaping it, and otherwise operating upon it, as illustrated upon
the drawings in Figs. 2 to 10 inclusive, substantially as, and for the purpose, herein
described.
"
"
2nd. The making of caster horns or brackets from a piece of parallel metal or
strip by bending and shaping it, and otherwise operating upon it, in combination with
a separate "eye," as illustrated upon the drawings in Figs. 7 & 11, substantially as, and
for the purposes herein described.
