Improvements in Fastenings for Metallic and other Bands, and
in Dies or Punches for Producing the same.
FRANCIS WILLIAM GOODE 4 Copt Hall Twickenham Forage Contractor. 1 do
hereby declare the nature of this invention to be as follows:-
:-
1st. The punching of a rectangular hole, by means of a punch, in one end of a strap
or band, as shewn in Fig. 1 in plan & cross-section.
2nd. The slotting & lipping of the opposite end of strap or band as shewn in plan &
cross-section, figs. 2 & 3.
3rd. The bringing together of the ends of the strap or band, inserting lips of one
end into slot formed at other end & clinching over as fig. 4, shewing fastening
completed in plan & cross-section.
Respecting the machine for carrying out the above operations, figs. 5, 6, & 7,
indicate the operation of the dies, these latter being actuated by cams or other means
in an ordinary die sinking machine.

FRANCIS WILLIAM GOODE 4 Copt Hall Twickenham Forage Contractor 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 :-
My invention relates to an improved fastening for bands of metal and other stiff
pliable material, in which the one part of the band has a rectangular hole formed in it
D

page_text: while the other part has a similarly shaped but slightly smaller hole with projecting
lips or flanges formed at two or more of its sides, so that, on passing the lips or flanges
of the last named part through the hole of the firstnamed part and then folding
the lips or flanges over its edges the two parts of the band will be securely held
together.
Figs. 1 to 4 of the drawings accompanying my Provisional Specification filed 25th
July 1886 shew the above described improved fastening. Fig. 1 shews a plan and
section of the part A having a rectangular hole punched in it, Fig. 2 shews a plan and
section of the part B with a similarly shaped but slightly smaller hole, having flanges
or lips bon two of its sides, such flanges being formed by slitting the band, as shewn
at Fig. 3 and then turning the slit parts up. Fig. 1 shews the parts A and B secured
together by passing the flanges through the hole of A. and then bending them
over.
For forming the lips or flanges on the part B I prefer to employ the arrange-
ment of dies or punches shewn at Figs. 5, 6 and 7. The metal band B having been
placed between guides on a table U having a gap of a size corresponding to the
outside dimensions of the lips or flanges to be produced, one part of the band situated
over the gap is supported by a sliding supporting die D, while a second die E formed
with a projecting beak e and a rounded shoulder e as shewn, descends and acting
against the edge of D and the ends of the gap first slits and partly bends down the
one lip by its beak e as at Fig. 5 after which both the dies descend together as at
Fig. 6, whereby E is made to slit and bend down the second lip by its shoulder and
cutting end faces acting against the end surfaces of the gap. The die E is
then raised so as to free the band from it by stops in the table, and the die D is
brought back to its original position as at Fig. 7. Any suitable arrangement of cams
or other devices such as are used in an ordinary die sinking machine may be employed
for imparting the above described movements to the dies, as will be readily understood
without further description.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :-
1. An improved fastening for metal and other bands wherein the one part of the
band has lips or flanges formed at the sides of a hole therein, which lips or flanges are
passed through a corresponding hole in the other part and are then bent over the edges
of such hole, substantially as herein described.
2. The method of producing the flanged hole in the one part of the band by means
of dies or punches, substantially as herein described.
3. The use for producing the flanged hole in the band referred to in the preceding
claims, of dies 1) and E constructed and operating as herein described.
