1 CHARLES SHOWELL, of Lower Loveday Street, Birmingham, Brassfounder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in castors for furniture and other similar
purposes, and refers more particularly to the manufacture of the horns, and the.
swivel pin, and their attachment to each other.
Upon the lower part of the socket, or upon the lower end of the swivel pin, or
attached to either of these or their equivalents is a pivot body in which is
preferably made a groove or grooves, or made taper or conical or otherwise shaped
suitably for the purposes hereinafter named.
A blank or strip of metal is now cut out, which is bent around the pivot body,
and pressed thereon or thereover in such a manner that the two outer ends form
that part of the horns wherein the roller pin is fixed, while its central part is
secured to the body so that it may carry or support the pivot and its super-
incumbent weight, but yet free to revolve. Or if desired this piece may be of
cast metal. If desired the lower end of the pivot may form a rivet. A second
piece is cut, stamped and shaped, or it may be cast, which is made to fit in between
the two parts of the horns before mentioned, and so completes the encircling of
the pivot body. This second piece is preferably furnished also with two horns
which lie inside those beforementioned, and thereby offer two thicknesses to
receive the weight and the pin. The said horns singly or both may be ribbed if
desired to increase strength. The two parts may be rivetted, soldered or clamped
to each other. The said parts may be of similar metal, or the interior piece may
be of an inferior or cheaper metal than the exterior.
Dated this 1st day of June 1895.

Improvements in Castors.
1 CHARLES SHOWELL of Lower Loveday Street, in the City of Birmingham
Brassfounder, 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 improvements in castors for furniture and other similar
purposes, and refers more particularly to the manufacture of the horns, and the
swivel pin, and their attachment to each other.
In order to more clearly explain this my invention I have appended hereunto an
illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring to the same thing or part.
Figs. 1 to 6, inclusive are detail views of the parts by which the horns are
formed.

page_text: Fig. 7, is a view of the pivOL DOу.
Fig. 8, is a sectional elevation of the castor..
Fig. 9, is a plan view of the castor.
Fig. 10, shows a modification by which antifriction balls or rings may be used.
A blank or flat strip of metal is cut out, which is bent and shaped as seen in
Figs. 1, 2, & 3, (Fig. 3 being a sectional view on line A-B) so as to fit around
the pivot body 14, and pressed thereon or thereover in such a manner that the two
outer ends 17, 17, form that part of the horn in which the roller pin is fixed, while
its central part 19 is secured upon the body so that it may carry the weight of the
furniture &c., to which it may be attached, but yet free to revolve. If desired
this piece may be of cast metal. The lower end of the pivot may if required be
made to form a rivet. A second piece is cut out, stamped and shaped, (or it may
be cast) which is made to fit in between the two parts 17, 17, of the horns before-
mentioned, shown on Figs. 1, 2, & 3, and so completes the encircling of the pivot
body. This second piece is furnished with two horns 20, 20, and central part 21,
which lie inside those beforementioned and thereby offer two thicknesses to receive
the weight and the pin 18. The said horns singly or both may be ribbed if desired
to increase strength. The two parts may be rivetted together by means of
rivets 22, 22, or soldered or otherwise secured to each other. The said parts
may be of similar metal, or the interior piece may be of an inferior or cheaper
metal than the exterior.
In some cases I may insert antifriction balls or rings as seen at 23, Fig. 10, to
facilitate the revolving of the horn upon the pivot body 14.
Having now particularly described and ascertained the nature of this my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. The forming of the horns of castors by means of an outer part consisting
of the horns 17, 17, and central part 19, and an inner part consisting of the
horns 20, 20, and central part 21, secured together, substantially as described and
shown.
2. In a castor the combination with a two part horn substantially as described
and shown of the pivot body 14, having grooves into which the said horn is fitted,
as set forth and shown.
3. The general combination and arrangement of construction of castors
substantially as herein described and illustrated.
