AN IMPROVED METHOD OF MAKING BOBBINS USED IN THE MANUFACTURE OF THREAD, SILK, COTTON AND OTHER GOODS
Year: 1885

page_text: I ERNEST AUBERY RICHARDS of 41 Icknield St. Birmingham in the County of
Warwick, Commercial Clerk do hereby declare the nature of my invention for
AN IMPROVED METHOD OF MAKING BOBBINS USED IN THE MANUFACTURE OF
THREAD, SILK, COTTON AND OTHER GOODS to be as follows:-
I first take two blanks of metal which have been previously shaped to the
required form with a hole pierced in the centre, and place them in dies of the
required shape in a stamp or other machine. I then take a blank which has either
a groove formed on the edge or one having a square, bevelled, flanged, or other
suitable shaped edge, and place it in the centre of the hole in the before mentioned
blanks, pressure is then applied by stamping or otherwise, and the centre blank is
pressed over the edges of the two pierced blanks, and so binding the three together
to form a complete Bobbin.
For large sizes I pierce several holes around the blanks instead of one large one,
and in the centre of each hole place a blank which is forced over the edges of the
two blanks by pressure as before described; or I take two blanks of metal shaped
to the required form, and place a thin blank or disc of solder between. the two
outer blanks, the two blanks, and disc are then held together by clamping or any
other suitable manner, and then subjected to sufficient heat to fuse or melt the
solder till the two metal blanks are fixed together by the solder disc, and when
cooled are ready for finishing.

I, ERNEST AUBREY RICHARDS of 41 Icknield Street, Birmingham, in the county
of Warwick, Brassfounder do hereby declare the nature of this my invention for
AN IMPROVED METHOD OF MAKING LACE BOBBINS USED IN THE MANUFACTURE OF
THREAD, SILK, COTTON, AND OTHER TEXTILE FABRICS, and in what manner the
saine is to be performed, to be particularly described and ascertained in and by
the following statement :-
This inventions consists of an improved method of making lace bobbins used in
the manufacture of silk, cotton, thread, and other fabrics.
I first take two blanks which have been previously shaped to the required form
with a hole pierced in the centre, and place them in dies of the required shape, in a
stamp or other machine.
I then take a blank which may have either a groove or flange in the centre of the
edge, or, one having a square bevilled edge, and place it in the hole in the before
mentioned blanks.
Pressure is then applied by stamping or otherwise, and then the central blank is
pressed over the edge of the two pierced blanks, so binding the three together to
form a complete .bobbin.
For large sizes I pierce several holes around the blank instead of a large one in
the centre, and in each hole place a blank, the metal of which is forced over the
edges of the blanks by pressure as before described.
Secondly I take two blanks of metal shaped to the requisite form, and place a
thin blank or disc of solder between the two outer blanks; the blanks and disc are
then held together by clamping, or any other suitable device, and placed in a
muffle or furnace, and heated until the two blanks are fused together by the
Bolder, they are then withdrawn, and allowed to cool, when they are ready for
finishing.
I will now further and more completely describe this my invention by the
assistance of the accompanying drawings which have thereon figures and letters of
reference..
Fig. 1 is a front elevation and section of one form of blank as prepared for
constructing a bobbin. In shaping these blanks I place the rough plain cut blank
in suitable dies, and by pressure, (as by stamping for instance) form them to the
required shape, as shewn, for example.
Or I may form them'if desired by a cutting tool, as in turning. I find however
the forming by pressure to be novel and effective in most if not all cases.
To further ensure the rigidity of the parts when secured, I may provide recesses
or notches in the edge of the central hole as shewn at J.
Fig. 2 is the central blank upon, and by which the two blanks (Fig. 1) are
bound together, a, b, c, d & n, being different sections in which the blank may be
formed

page_text: Fig. 3 shews the two outer blanks e, f, placed upon the central blank g, ready
for the latter to receive pressure for closing.
Fig. 4 shews the closing having taken place and the surplus metal of the central
blank removed; the three blanks being firmly fastened together, and thus forming
a complete bobbin. It will be seen that in closing, the metal of the central blank
is folded over, or pressed into the bevilled countersink in the outer blanks at h.
It is not however absolutely necessary I find either to have a countersunk formed
upon the outer blanks, nor yet to have flanges or grooves in the central blanks, as
with a plain central blank as at d, Fig. 2, the pressure is sufficient to secure them.
Fig. 5 shews a number of holes to receive a corresponding number of blanks
instead of one central blank. The shape (section) of these blanks may be precisely
the same as in the case of the larger central one, and folded over, securing the two
outer blanks also in the same manner as described for Figs. 3 & 4.
Fig. 6, shews a blank formed to construct a bobbin, with a central blank, formed
of solder.
Fig. 7, is this thin disc, or blank of solder for uniting the two blanks together.
Fig. 8 shews the two outer blanks and. the central blank of solder in position
ready to be heated until the solder shall fuse together with the parts of the outer
blanks adjoining it, so that the three blanks are thus firmly united.
Although I have shewn a square hole in the centre of the bobbins, and drawn
the various parts of the bobbin in the manner shewn, I do not confine myself to
those precise forms or shapes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
First. The forming of the blanks as in Figs. 1, 5 & 6, by pressure, as for instance
by stamping or in other similar machine.
Second. The uniting together of the two blanks forming a bobbin, by means of
a central blank or blanks, similar as shown in Figs. 1, 2, 3, 4 & 5.
Third. The uniting of the two blanks forming a bobbin by means of a disc of
solder as shewn in Fig. 6, 7 & 8, or any mere modification of the same.
Dated this 28th day of October 1885.
