Improvements in Castorhorn Rings and the Mode of
Manufacturing same.
I GEORGE ROE of 48 Whitmore Street Hockley, Birmingham in the County of
Warwick Traveller, do hereby declare the nature of my said inventition to be as
follows:-
My invention has for its object improvements in castorhorn rings and the mode of
manufacturing same, which enables me to produce the same with greater facility
than formerly. For the manufacture of these rings I proceed as follows:-
I first take a blank of metal say brass and turn up the sides under the press into
the shape of a cup. I next form a bead at the bottom of the sides externally. I
then pierce the bottom of the cup. This forms one half or part of the castorhorn ring.
In forming the other part I flange up the disc as the first process, then pierce the
said disc, then turn up a part of the base of the metal into a tubular shape or as a
vertical flange. I then place the vertical flange of the second ring inside the pierced
base of the first part and turn over the vertical flange so as to lock the two together
and press them into the required shape for the internal flange and external bead
which finishes the article.
By this process of manufacture, and the combination of the two parts I am able
to complete the whole by press work in an expeditious, cheap and satisfactory
manner.

Improvements in Castorhorn Rings and the Mode of
Manufacturing same.
I, GEORGE ROE of 48 Whitmore Street Hockley Birmingham in the County of
Warwick Traveller, do hereby declare the nature of my said 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 for its object improvements in castor-horn rings and the mode of
manufacturing same which enabies me to produce the same with greater facility than
formerly. For the manufacture of these rings I proceed as follows:-
I first take a blank of metal say brass and turn up the sides under the press into
the shape of a cup I next form a bead at the bottom of the sides externally I then
pierce the bottom of the cap. This forms one half or part of the castor-horn ring.
In forming the other part I flange up the disc as the first process then pierce the said
disc then turning up a part of the base of the metal into a tubular shape or as a

page_text: vertical flange. I then place the vertical flange of the second ring inside the pierced
base of the first part and turn over the vertical flange so as to lock the two together
and press them into the required shape for the internal flange and external bead
which finishes the article. By this process of manufacture and the combination
of the two parts I am able to complete the whole by press work in an expeditious, 5
cheap and satisfactory manner.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawing upon which
I have illustrated the various processes through which the metal blanks pass in
forming my caster horn rings.
Figure 1 is an elevation shewing my castor horn ring R complete.
Figure 2 shews the metal blank from which the part R¹ is formed.
Figure 3 shews this blank after it has passed through the first process.
Figure 4 shews the part R¹ after it has passed through the second process.
Figure 5 is a plan view of Figure 4 with the centre portion pierced or cut out.
Figure 6 shews the metal blank from which the part R2 is formed.
Figure 7 shews this metal blank after it has passed through the first process.
Figure 8 is a plan view of Figure 7 shewing the centre portion pierced or cut out.
Figure 9 shews the part R2 after it has been passed through another pair of
tools.
Figure 10 is a plan view of Figure 9.
Figure 11 is a sectional elevation shewing the two parts placed together ready for
the last operation.
Figure 12 is a sectional elevation of Figure 1 shewing the two parts put together
and the castor-horn ring complete.
Figure 13 is a similar view to Figure 12 shewing a modification in the mode of
joining the two parts together.
In carrying my invention into practice I first take the blank of metal say brass as
shewn at Figure 2 and bend or turn up the sides by suitable tools under the press in
the shape of a cup as shewn at Figure 3. I then place this cup in an inverted
position under another set of tools which forms the bead or bulge at the bottom
of the sides externally as clearly shewn at Figure 4. The bottom of this cup is then
pierced as shewn at Figure 5 and the one portion or part R¹ of the castor-horn ring
is now complete. In forming the other part or portion I take the blank of metal say
brass as shewn at Figure 6 and bend or flange up the edges under a press as shewn
at Figure 7 in a similar manner as with the first blank the centre is next pierced as
shewn at Figure 8 and then a portion of the base is turned or forced outwards by
another set of tools so as to form the vertical flange r as shewn at Figures 9 and 10.
The other portion R2 of the castor-horn ring is now complete. I then place the
vertical flange inside the pierced base of the part R! as shewn at Figure 11 and
this flange is then turned over onto the inner edges of the pierced base by another
set of tools so as to lock the two together as clearly shewn at Figure 12 which finishes
the article.
In the modification as shewn at Figure 13 I form the external bead 5 on the base
of the part R¹ so that when the two parts are united this head extends down the sides
of the part R2 but it will be quite evident that the configuration of this bead may be
varied by a slight alteration to the tools.
Castor-horn rings made in two parts in the manner as herein described can be
manufactured quickly and cheaply in a satisfactory and well finished manner.
Having now particularly described and ascertained the nature of my said
and in what manner the same is to be performed I declare that what I claim is
CLAIMS.

page_text: substantially as herein before described and as shown upon the accompanying sheet
of drawings.
Second-Castor-horn rings formed from two portions or metal blanks R¹ and R²
which are bent in dies or tools step by step as herein explained and such as shewn
which two portions are suitably formed to lock together so as to become substantially
one article such as shown at Figures 1, 12 and 13.
