An Improved Castor for Furniture and the like.
CHARLES OTTO SCHNEIDER, Engineer, 37, Pandora Road, West Hampstead,
and HENRY BACHMAN, Engineer, 104, Wharton Road, Shepherd's Bush, do
hereby declare the nature of this invention to be as follows:
The object of this invention is to simplify the construction of socalled horns
or forks for furniture castors; and the like.
The horns are somewhat similar to those stamped from sheet metal with how-
ever two or more shoulders or flanges in extension thereof.
In each flange we stamp a hole of the size of the pivotpin.
The blank is then bent to shape by means of suitable punches or dies, the
flanges to be either inwards or outwards, so as to bring the holes in one straight
line to allow the pivotpin to enter and revolve freely.

An Improved Castor for Furniture and the like.
We, CHARLES OTTO SCHNEIDER, Engineer, 37, Pandora Road, West Hamp-
stead, London, and HENRY BACHMAN, Engineer, 104, Wharton Road, Shepherd's
Bush, London, 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:-
The present invention has reference to the construction of the so-called "horns"
for furniture castors, the object being to facilitate and cheapen the manufacture,
and to ensure a strong and satisfactory construction in the result.
In carrying out this invention, a sheet metal blank is prepared of suitable
contour, and submitted to the action of a powerful plunger and die, by means
of which the blank is pressed into the form desired in one operation.
In the accompanying drawing is shown the sheet metal blank and the horns
in the form they ultimately assume, and also the die and plunger whereby the
result is obtained.
Fig. 1 is a side view of the die, partly in section, with the plunger raised
ready to decend upon the work.
Fig. 2 is a plan view of Fig. 1, without the plunger.

page_text: Fig. 3 is a sectional side view, showing the die containing the blank, and the
plunger at the bottom of its downward stroke.
Fig. 4 is a sectional view taken at right angles to Fig. 3, with the parts in
similar positions.
Figs. 5, are edge and plan views of the metal blank, from which the horns
are formed.
Figs. 6 are back and plan views of the horns when in shape, and
Fig. 7 is a side view of the horns, with the pivot pin which attaches the castor
to the furniture fixed therein.
A is the blank, stamped from suitable sheet metal. The blank A has, on
either side, arms b, b, which are intended to form the fork for the castor wheel,
and are provided with holes b¹ to receive its axle. ce are other projecting portions
extending from opposite sides of the blank, in directions at right angles to the
direction of the arms b, c c are holes in the projections c, which eventually
come into line, and form a socket for the pivot pin . D is the die, consisting
of a block of steel having a central rectangular hole, into which the plunger Di
is fitted to descend. The blank A is laid upon the die within a guide plate d,
(see Fig. 2), cut out to correspond with the shape of the blank. When the
plunger descends, the metal blank is driven by it into the die, and the armis bb
and projections ce are bent up into the form shewn, each pair being now parallel,
and presenting their holes duly in line. dare cuts in the side of the die
(see Figs. 2 and 4), to accommodate the arms b, b, in their bent-up position.
The bottom of the die is preferably provided with a loose block, having on
its upper side a semi-circular groove (see Figs. 1 and 3), which, with the plunger
which is correspondingly formed gives to the back of the stamping a semi-circular
recess. This recess being adjacent to the holes c¹, c¹, before mentioned, makes a
suitable bearing for the pivot pin &, when it passes through the said holes.
e is a small plunger beneath the loose block d³, by means of which the horns
can be ejected from the die.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
wo claim is:-
Horns for furniture castors manufactured from sheet metal blanks, and com-
prising a socket for the pivot pin made by turning over into a parallel position,
pierced projecting portions, substantially as set forth with reference to the
accompanying drawings.
