IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF WROUGHT METAL NAILS
Year: 1884

page_text: I EDWARD ARTHUR LEE of Dos Works Newport in the County of Monmouth
Nail Manufacturer do hereby declare the nature of my invention for
"IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF WROUGHT METAL
NAILS" to be as follows:-
•
This invention relates to improvements in that class of machinery for the
manufacture of wrought metal nails in which a nail rod is fed into the machine
and passes between shaping rollers from which a nail blank is taken by a pair of
reciprocating slides or dies which hold the blank whilst it passes between a pair of
finishing segmental dies or rollers.
Now my improvements consist in so arranging and actuating the series of slides
dies and rollers that the reciprocating slides or dies hold the blank as it leaves
the finishing rollers with a short length projecting from them. The blank is then
taken hold of by another pair of dies which bold the blank firmly whilst the
header comes into operation to head and thus complete the nail before it leaves the
machine.
The header and the holding dies or slides are actuated by cams and eccentrics on
the main shaft or driving axis.

Nail Manufacturer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF WROUGHT METAL NAILS" 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 improvements in that class of machinery for the
mánufacture of wrought metal nails in which a heated nail rod is fed into the
machine and passes between shaping rollers from which a nail blank is taken by a
pair of reciprocating slides or dies which hold the blank whilst it passes between
a pair of finishing segmental dies or rollers.
Now my improvements consist in so arranging and actuating the series of slides"
dies and rollers that the reciprocating slides or dies hold the blank as it leaves the
finishing rollers with a short length projecting from them. The blank is then
taken hold of by another pair of dies which hold the blank firmly whilst the
header comes into operation to head and thus complete the nail before it leaves the
machine.
The header and the holding dies or slides are actuated by cams and eccentrics on
the main shaft or driving axis.
And in order that my invention may be clearly understood and readily
carried into practice I will proceed to describe the Drawings hereto annexed which
show so much of a machine for the manufacture of wrought metal nails as will
enable me to describe the nature of my improvements.
The general arrangement of machinery of this character being well understood
by those acquainted with the manufacture of wrought metal nails it will not be
necessary for me to show and describe more of the ordinary working parts of the
machine than may be required to explain the nature and application of my
improvements.
The nail blank a after passing through the shaping rollers A A (which feed the
heated nail rod forward) is taken hold of on each side by a pair of reciprocating
slides b. b. The slides 6 then carry the blank a forward between the segmental
rollers c. c. which further press and shape the nail blank and carry it forward with
a suitable length projecting from the front end of the slides to form the head of
the nail and Figures 1 and 2 of the drawings show the operating parts in the
position they assume just before the operation of heading takes place.
As the blank is carried forward the gripping dies d. d. carried by the levers d². d¹.
and actuated by the cam surfaces d. d. on the cam shaft d³ are caused to hold the
blank firmly above and below whilst the header e actuated by the cam surface e¹
comes forward to compress the projecting portion of the blank to form the head
of the finished nail as shown by Figure 3.
One of the slides b moves sideways at the same time the gripping dies release
the finished nail which is caused to fall away from the dies by means of a spring
which is brought into action to press against the nail to ensure its delivery.
Figure 3 shows the position of the parts when the heading operation takes
place.
.
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 improved arrangement and combination of mechanism for the
manufacture of wrought metal nails in which the metal blank a as it leaves the

page_text: finishing rolls is held on each side between the slides or dies b. b. and by the
gripping dies d. d. above and below whilst the header e comes forward to head and
finish the nail substantially in the manner hereinbefore described and represented
in the Drawings annexed.
Second I claim the combination of the slides b. b. with the dies d. d. for holding
the blank in position ready for being headed as herein described.
I also claim the combination of the dies d. d. with the header e actuated
substantially as herein described and represented in the Drawings annexed.
I also claim the combination of the slides b. b. with the header e the slides b. b.
acting so as to present the end of the blank to the gripping dies d. d. and header e
substantially as herein described and represented in the drawings annexed.
