IMPROVEMENTS IN THE MANUFACTURE OF METALLIC FASTENINGS FOR ATTACHING BUTTONS TO FABRICS
Year: 1884

page_text: I, SYDNEY PITT of Sutton in the County of Surrey do hereby declare the
nature of my Invention for "IMPROVEMENTS IN THE MANUFACTURE OF METALLIC
FASTENINGS FOR ATTACHING BUTTONS TO FABRICS" and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
This Invention has for its object improvements in the manufacture of metallic.
fastenings for attaching buttons to fabrics.
For this purpose I cut or stamp out such fastenings from strips of metal rolled to
an irregular configuration-usually I make such strips tapered to one or both of
their side edges but they might be of other form.
At Figure 1 of the Drawings hereunto annexed I have shewn cross sections of a
variety of forms to which I roll the strips of metal from which the fasteners are to
be stamped or cut. The sections are marked a, b, c, d, e and n.
Figures 2 to 9 shew various forms of fastener stamped or cut from one or other
of such sections of strip metal.
The section marked a is of uniform thickness in the centre and tapered to an
edge on either side, it is peculiarly adapted for the fasteners shewn in Figure 2 as
the table or central portion of such fasteners can thus be made flat whilst the
prongs are gradually tapered to a sharp point so saving any further manipulation
in their manufacture. The forms of fastener shewn at Figure 2 can also be made
from the sections of strip shewn in Figure 1 at c or e.
When the section of strip
shewn at e is used the fasteners are cut or stamped out lengthwise from the strip
but when any of the other sections are used the fasteners are always cut or stamped
out crosswise.
When the fasteners are cut or stamped lengthwise from the stripe the middle
prong will be cut entirely from the thin middle portion of the strip this renders the
eye or loop a¹ of the fastener easier to bend.
In the sections of strip shewn at c or b in Figure 1 the central part of the strip
is angled or rounded as shewn which makes a fastener with a thick centre and
tapered points.

page_text: The fastener shown at Figure 2° is the same as that shewn at Figure 2 except
that the eye a¹ is dispensed with: like Figure 2 it can be formed from any of the
sections of strip shewn at a, b, c or e. Figures 3 and 3* show two forms of a one
prong fastener or tack; both of these may be made either from the section of strip
shown at d or that shewn at n. Figure 4 shews a two prong fastening cut from a
taper strip such as shewn at d the fastening can so be made with a broad body and
sharpened points. Figure 5 shows a two prong staple fastener formed out a strip
cut or stamped from the section b and bent into the form shewn-the eye or centre
of such fastener will be broad and. the legs tapered. Figure 6 shews a three prong
fastener-it is formed from a blank shewn at Figure 6º cut from a strip of section d
and bent to a right angle or other desired angle. Fasteners of this kind will have
a broad head bar and taper sharpened prongs. Figures 7 and 9 shew various forms
of fastener which are cut or stamped from strips of the section shewn at ‹ or n.
Figure 8 shews a hook fastener cut or stamped from section n making a broad head
and thin hook.
Although in the Drawings I have shewn various forms of fastener made as above
described from strips of metal rolled to an irregular section I do not restrict myself
to these forms of fastener as fasteners of other shape may similarly be formed from
strips rolled to a cross section of varying thickness. The forms of fastener shewn
are however the forms which I prefer to adopt. The object of cutting or stamping
the fasteners from strips of metal of varying thickness is to obviate the necessity
of drawing or swaging the points and also to form the fasteners with a table of
thicker substance than the prongs or hooks. The fasteners with the exception of
the ones shewn in Figures 2 and 2 are cut direct to form and shape out of the
strips of metal without any bending or further manipulation of the metal leaving
the metal of the finished fastener in the same condition in which it existed in the
strip from which it was cut. The fasteners shewn in Figures 2 and 2 are bent
to the forms shewn from a blank such as shown at Figures 2b cut or stamped from
a metal strip of the section a but as before stated similar fasteners might be formed
from metal strips of the sections shewn at b, c or e.
Having thus described the nature of the Invention and the manner of porforming
the same 1 would have it understood that I claim :-
First. The manufacture of button fasteners from strips of metal of varying
thickness substantially as herein before described.
Second-The manufacture of button fasteners substantially as herein before
described from strips of metal of the forms illustrated in the Drawings annexed.
Third. The various constructions of button fasteners substantially as herein
before described and shewn in the Drawings annexed.
