PROVISIONAL SPECIFICATION.
Improvements in Machines for the Manufacture of Nails.
I, THOMAS GARE, of The Gare Machine Co. Ltd., of Hopes Carr, Stockport,
in the County of Chester, Engineer, do hereby declare the nature of this invention
to be as follows :-
This invention relates to an improved construction of machine for the manufacture
of taper or chisel pointed nails or nails having heads projecting on two or all four
sides, formed from specially sectioned or profiled metal ribbons, strips, or bars, such
as are described in Letters Patent granted to me November, 16th 1891, No. 19823,
and the like and has for its object to render such machines more efficient, simple
in construction and to increase their productive capacity.
Heretofore the knives, cutters or shears, or dies and punches employed in
machines for the manufacture of nails from metal ribbons, strips, or bars have been
arranged on the reciprocatory principal, which entails a loss of time and requires a
considerable amount of power.
The object of my invention is to obviate these defects and consists in the con-
struction of a machine in which the nails are cut from suitably sectioned or
profiled metal ribbons, strips, or bars, by one or more shear blades or punches
arranged to rotate continuously and operate in conjunction with one or more
stationary shear blades or dies respectively serving also as a support or supports
for the said metal ribbons, strips, or bars.
This may be carried out in various ways:-
When forming taper or chisel pointed nails or nails having heads projecting on
two sides only, I employ a disc, plate, or part suitably rotated and having on its
side or face one or more shear blades arranged to move in and out of contact with
one or more-stationary shear blades having a groove or slot adapted to guide
and support the metal ribbon, strip, or bar from which the nails are cut which
latter may be fed through the said groove or slot by hand or mechanically. The
shear blades on the said rotating disc, plate, or part are arranged in such a manner,
as to provide a space between the same into which, when opposite the aforesaid
groove or slot, the said metal ribbon, strip, or bar is projected, so as to cause the
said shear blades to come successively into contact with and cut each time a nail
from the said metal ribbon, strip, or bar.
When feeding the said metal ribbon, strip, or bar by hand, the thickness of the
nail to be cut depends on the depth of the space or thickness of the shear blades
on the said rotating disc, plate, or part, whilst when the metal ribbon, strip, or bar
is fed mechanically the depth of the said space or thickness of the shear blades
may be in excess of that of the nail to be cut.
Chisel pointed nails may be cut from a flat sectioned metal ribbon, strip, or bar
by forming the shear blades on the said rotating disc, plate, or part with an inclined
cutting edge and by feeding the metal ribbon, strip, or bar through a bush, having
a correspondingly inclined face, arranged to be rotated reciprocatory in a stationary
support.
When forming nails, with heads projecting on all four sides, from suitably
sectioned or profiled metal ribbons, strips, or bars, one or more punches, in
configuration corresponding with the section of the metal ribbon, strip, or bar,
or nail to be produced, are fixed to or formed on the periphery of a rotating
disc, plate, shaft or part and adapted to operate in conjunction with a stationary
die or support suitably arranged. The said die or support is also formed with

page_text: a groove or slot through which the said metal ribbons, strips, or bars are fed
and brought into the course of the said punches either by hand or mechanically.
The punch or die arrangement described, is also applicable for the manufacture
of taper or chisel pointed nails from a tapered sectioned metal ribbon, strip, or
bar, or straight nails from a flat sectioned one, and by feeding the same in
distance double the nail thickness, two nails can be produced at one operation.
Large nails with heads on all four sides may be similarly produced in two
operations, by employing on the said rotating disc, plate, shaft, or part two
different punches or cutters in alternate order, one serving to punch out of the
shank portion of the metal ribbon, strip, or bar, the piece or waste between two
nails and the other to cut the head portion thereof and thus sever, the nail.

COMELI DI MULTIUATION.
Improvements in Machines for the Manufacture of Nails.
I, THOMAS GARE, of the Gare Machine Co. Ltd., of Hopes Carr, Stockport,
in the County of Chester, Engineer, do hereby declare the nature of this invention
I 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 an improved construction of machines for the manufacture
of taper or chisel pointed nails or nails having heads projecting on two or all
four sides, formed from specially sectioned or profiled metal ribbons, strips, or
bars, such as are described in Letters Patent granted to me November, 16th 1891,
No. 19823, and the like and has for its object to render such machines more
efficient, simple in construction and to increase their productive capacity.
Heretofore the knives, cutters or shears, or dies and punches employed in
machines for the manufacture of nails from metal ribbons, strips, or bars have
been arranged on the reciprocatory principal, which entails a loss of 'time and
requires a considerable amount of power.
The object of my invention is to obviate these defects and consists in the
construction of a machine in which the nails are .cut from suitably sectioned or
profiled metal ribbons, strips, or bars, by one or more shear blades or punches
arranged to rotate continuously and operate in conjunction with one or more.
stationary shear blades or dies respectively serving also as a support or supports
for the said metal ribbons, strips, or bars.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section and Figs. 2 & 3 are end views of the main part of
a machine for producing nails with heads projecting on two sides, constructed in
accordance with my invention.
Fig. 4 is an end view and Fig. 5 a plan showing a modification of Figs. 1, 2 & 3,
and adapted to produce chisel pointed nails from a flat metal ribbon, strip, or bar:
Fig. 6 is a side view, Fig. 7 an end view and Fig. 8 a sectional plan of a machine
for producing nails with heads on all four sides.
Fig. 9 shows a modified method of feeding the nail ribbon, strip, or bar so as to
produce two nails at one operation of the cutter or punch.
Figs. 10 & 11 are respectively an end view and a plan of a modification of
Figs. 6, 7 & 8 adapted to produce nails with heads projecting on all four sides at
two operations.
Fig. 12 is a longitudinal section and Fig. 13 an end view of a machine for cutting

page_text: or punching out the waste part of profiled metal ribbons, strips, or bars adapted for
the manufacture of nails with heads projecting on four sides for use in nailing
smachines which form their own nails.
This may be carried out in various ways:-
Referring to Figs. 1, 2 & 3, when forming taper or chisel pointed nails, or nails
having heads projecting on two sides only, I employ a disc, plate, or other suitably
shaped part a adapted to carry on its side or face and rotate one or more shear
blades 6 arranged to come in and out of contact with one or more stationary shear
blades or blocks c having a groove or slot d adapted to guide and support the
metal ribbon, strip or bare from which the nails are cut, which latter may be fed
through the groove or slot d by: hand or mechanically. The shear blades bare
arranged in such a manner, as to provide a space ƒ (Fig. 1.) between the same
into which, when opposite the groove or slot d, the metal ribbon, strip, or bar e
is projected, so as to cause the shear blades b to come successively into contact
with and cut each time a nail from the metal ribbon, strip, or bar e.
When feeding the metal ribbon, strip, or bar e by hand, the thickness of the nail
to be cut depends on the depth of the space or thickness of the shear blades 6 on
the rotating disc, plate or part a, whilst when the metal ribbon, strip or bar e is fed
mechanically the depth of the space for thickness of the shear blades 6 may be in
excess of that of the nail to be cut.
Referring to Figs. 4 & 5, chisel pointed nails may be cut from a flat sectioned
metal ribbon, strip, or bar e by forming the shear blades 6 on the rotating disc,
plate, or part a with an inclined cutting edge b¹ and by feeding the metal ribbon,
strip, or bare through a shear block c fitted into a bush g and having a corre-
spondingly inclined face 6' arranged to be rotated reciprocally in a stationary
support h, by such as a pinion gl secured upon the bush g and a segment g³ gearing
into the pinion gl and operated by a rod acted upon by a cam (not shown) or a rack
may be used in lieu of the segment g².
Referring to Figs. 6, 7, & 8, when forming nails, with heads projecting on all
four sides from suitably sectioned or profiled metal ribbons, strips, or bars e, one
or more cutters or punches i, in configuration corresponding with the section of
the metal-ribbon, strip, or bar e or nail to be produced are fixed to or formed on
the periphery of a rotating disc, plate, shaft or part a and adapted to operate in
conjunction with a stationary die or support suitably arranged. The die or
support is also formed with a groove or slot d through which the metal ribbons,
strips, or bars e are fed and brought into the path of the punches i either by hand
or mechanically.
The cutter or punch and die i & h arrangement described, also applicable for
the manufacture of taper or chisel pointed nails from a tapered sectioned metal
ribbon, strip, or bar e, or straight nails from a flat sectioned one, and by feeding
the same in distance double the nail thickness, as shown in Fig. 9, two nails can
be produced at one operation of the cutter or punch i.
Referring to Figs. 10 & 11, large nails with heads on all four sides may be
similarly produced in two operations, by employing on the rotating disc, plate,
shaft, or part a, a punch i operating in conjunction with the support or die h, the
edge c of which serves also as a shear blade or block in conjunction with the shear
blade b, adapted respectively to cut or punch out of the shank portion of the metal
ribbon, strip, or bar e, the piece or waste el between two nails and cut or shear
through the head portion thereof in alternate order. By dispensing with the
shear blade b, the machine described and illustrated in Figs. 10 & 11 may be used
for cutting or punching out the waste piece e¹ only and thus provide notched nail
ribbons, strips or bars e for use in nailing machines.
As shown in Figs. 12 & 13 the cutters or punches i adapted to cut or punch
out the waste piece e of the metal ribbon, strip, or bar e, may also be employed
on the face of the disc, plate or part a the spindle 1 of the latter being formed
hollow to allow the metal ribbon, strip, or bare of being fed through it. In this
case a bush l¹is employed in the spindle to support the respective end of the

page_text: metal ribbon, strip, or har e whilst the shear block c bears against the cutters.or
punctures as shown in Fig. 1.
In the manufacture of nails as described, the nail ribbon, strip or bar may be
operated upon in a cold or in a hot state, in the latter case a suitable furnace
-connected with the shearing or punching apparatus may be employed through
which the nail ribbon, strip, or bar is drawn.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what.I
claim, is
..
-
1st. The general construction and combination of parts constituting my improve-
ments operating substantially as and for the purpose set forth.
2nd. The employment of one or more continuously rotated shear blades or
punches 6 or in combination with one or more stationary shear blades or blocks c
or dies h respectively, substantially as and for the purpose specified.
3rd. A disc, plate or other suitably shaped part a carrying on one side or face
one or more shear or punch blades b & i adapted to rotate continuously and come
in contact alternately with the end or face of a stationary or a reciprocally rotated
shear blade or block c which latter serves also to support the nail ribbon, strip or
bar e, substantially as and for the purpose specified.
4th. A disc, plate or other suitably shaped part a carrying on its circumference
one or more shear blades and punches 6 & i adapted to rotate continuously and
come in contact alternately with a corresponding shear part c and die respectively,
-the said die and shear part serving also as a support for the nail ribbon, strip, or
bar e; substantially as and for the purpose specified.
5th. The employment of cutters or punches i either on the face or circumference
-of the disc, plate or part a adapted to cut or punch out the waste part e' of the
nail ribbon, strip or bar e only, substantially as and for the purpose set forth.
