I, OLIVER GRIFFITHS GOODMAN of Caroline Street, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention te be
as follows:
This invention has relation to a feed for the delivery of the stems or wire
blanks from the hopper feed to the delivery wheel, which carries the stems round
to the coiling die.
Heretofore the stems have been taken from the hopper feed from the bottom,
and in consequence of the stems lying in a pile one above another, and from other
causes, the feed is at times irregular.
According to my improvements the stems or wire blanks to be employed in forming
nursery, safety, curtain and like pins or articles, are taken from the top of the
hopper, whereby an uninterrupted feed is effected.
The improvements consists essentially in the employment of a pair of tools, one
descending and one ascending, the ascending tool passes upwardly through the pile
of stems laid in the hopper, whilst the descending tool meets the ascending tool as it
emerges from the pile with a stem lying longitudinally within a groove in the top
edge of it.
Thus in carrying out my improvements, I take a hopper and pass a tool upwardly
through its bottom, and with the same having a rising and falling motion equal to
the pile of stems, or to the depth of the hopper when full.
The top edge on this lower tool is longitudinally channelled or grooved to a
depth a little less than the thickness of a stem to be fed, and with the middle part
of channel gapped so as to form a double seating for the stem to lie within.
This lower tool may be made alike unto a bar, and so also may the upper tool
which may be chisel pointed or otherwise formed at its acting or contact end.
The upper tool which works in the same vertical plane as the lower tool,
is disposed at right angles to it, so that when the said tools come together with a
stem between them, the upper one crosses the stem about its middle.
The lower tool works within guides, and is worked from off a rocking beam,
whose one end is connected to the lower end of the said lower tool and the other end
jointedly connected to an adjustable slide worked from off a crank or excentric
on the main shaft of the machine through the medium of a coupling or connecting
rod.
Instead of employing a carrier wheel for taking the stems into the dies, I may
use an ordinary finger motion for this purpose.
The upper tool is made to descend through the medium of a spring and follows
the lower tool to the top of the pile of stems in the hopper, when it is arrested
until the lower tool again ascends and meets the said top tool with a stem between
them, which stem is thus carried to the carrier wheel or finger motion, and then
released by a cam or other motion acting upon or retaining the upper tool.

1, OLIVER GRIFFITHS GOODMAN, of Caroline Street, in the City of
Birmingham, Manufacturer, 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: -
This invention has relation to a feed for the delivery of the stems or wire blanks
from the hopper feed to the carrier or finger motion which transfers the said stems
or wire blanks to the forming die and coiling head stock.
Heretofore the stems or blanks have been taken from the bottom of the hopper
feed and in consequence of the said blanks lying in a pile one above another and
from other causes the feed is at times irregular.
According to my improvements the stems or wire blanks to be employed in
forming nursery, safety, curtain and like pins or articles, are taken from the top of
the hopper, whereby an uninterrupted feed is effected.
The im sements consists essentially in the employment of a pair of approaching
tools, the lower one of which passes upwardly through the pile of stems laid in the
hopper, whilst the other and upper tool meets the lower tool as it emerges from the
pile with a stem lying longitudinally within a groove in the top edge of it.
Thus in carrying out my improvements, I take a hopper and pass a tool upwardly
through its bottom, and with the same having a rising and falling motion somewhat
greater than the depth of the hopper when full.
The top edge of this lower tool is longitudinally channelled or grooved to a depth
ths than the thickne of a stem to be fed.
This lower tool may be made alike unto a bar, and so also may the upper
tool which may he chisil pointed or otherwise formed at its acting or contact end.
Beth the lower and upper to work within guides, and are actuated by rocking
levers or beams receiving their motim from off cranks, cams or excentries on the
main driving shaft of the machine.
The upper tool is made to descend through the medium of a spring and follows the
lower tool to the top of the pile of stems in the hopper, when it is arrested until
the lower tool again ascends and meets the said top tool with a stem between them,
which stem is this carried to the coiling headstock by the finger motion or carrier,
and then released by a cam or other motion acting upon or retaining the upper tool,
whilst the sail tools recede from one another simultaneous with the forward
movement of the finger motion.
Figure 1 of the accompanying drawings represents a front elevation, with some
of the parts in section of mechanism for the feeding of safety pin and like stems or
Blanks to the coiling head stock constructed, arranged and operated according to
my invention.
Figure 2 is a cross section of Figure 1 upon the dotted line -
Figure 3 is a back elevation of the said machine turned round.
Figure 4 is a cross section of Figure 3 upon the dotted line c'.
Figure 5 is a topside plan of the machine, and
Figure 6 is an end view of the same.
Figure 7 is a section of the finger for transporting of a stem or blank to the
coiling headstock.
Figure 8 shows an elevation and an edge view of the extractor tool
separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the feed hopper, with an open top a', and an open bottom a³, resting upon the
topside, of a bed b, supported by legs 6, and having passing and working

page_text: vertically through it, a lower blank-extracting tool c, reciprocating within gaides 63,
and passing through a hole, in the bed b, and having a lower and rollered end c,
coming or impinging by gravity upon an end d', of a lever d, fulcrumed at d², and
drawn back by a coiled spring d³, and with the rounded end d, following the
periphery of a came, made fast upon the main shaft f, which is driven by a fast
pulley, and fitted with a loose pulley h, and a fly wheel i, for steadying the
movement.
The upper and reciprocating clamping tool j, works within guides j', supported
by a fixed framing, supported upon the bed and falls by gravity onto the top of
the stem lying within the groove in the upper edge of the extracting tool, which
nearly meets the opposed end of the clamping tool.
The said clamping tool is regulated in its descent by a lever k, jointed at k³, to an
upright, of the framing and with the short end, of the sail lever resting upon
a descent-regulating cam², made fast on the shaft whilst the other end k*,
impinges upon a rollered bearing j, carried upon the gripping tool j.
is a racking arm, fulerumed at m, to a fast depending bracket m², and having
a short arm m³, which impinges upon a shoe n², carriel at the extreme en 1 of the
long arm n', of a lever n, fulcrumed at 2, and with its short arm at, bearing upon
the cam, made fast on the principal driving shaft, and with the said rocking
arm m, having its forward movement imparted to it by the said lever n, and being
brought back by a spring m, whilst the upper part m, carries a pair of fingers m,
having curled-ended nipping springs m', which grip the stem or blank p, on the two
opposite sides of the extractor and carry the same forward to the coiling head
stock o, mounted on a shaft o', driven by gear of as is usual.
OPERATION.
Assuming that a stem blank has been taken from the hopper feed and held
between the extracting and clamping tool, as represented in Figures 1, 3, 5 and 6
of the drawings, the continued movement of the shaft, rotates the camnand
through the lever n, the short arm m³, of the rocking arm m is lifted, and the said
rocking arm is brought over from the right to the teit hami side of the hoppet feed,
and in its traverse, the stem p, lying within the path of the end of the finger m², is
gripped between the free end of the springs a', and the fore part of the said finger
and is then transported to the coiling head stock and fashioned in the usual way,
the said tools and j, falling away or receding from one another simultaneously.
As the finger advances, so the upper and lower tools are caused to recede or
retire from one another by the cams on the shaft, thus leaving a free movement of
the rocking arm, which, after the stem has been taken up by the coiling head stock,
then returns to its normal position, with the gripping to il being fully raised and the
grooved upper end of the extracting tool below the bottom of the pile of stems or
blanks in the hopper.
The cam, now ceases to act thus leaving the rocking arm m, quiescent and in
a back position. Then as the cams 13, e, rotate by the revolution of the shaft, the
extractor e is lifted bodily through the pile displacing the blanks in its path and
carrying with it, one of the blanks from the top layer, which is thus lifted beyond
the top of the pile and clear of the hopper, and is met and held by the clamping
tool, which has been allowed to gradually descend by its own weight.
The finger now comes forward and the operation of transferring the blank
is repeated as before after which the levers are caused to resume their normal
positions by the aid of the springs.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what I
claim is :-
First. A feed for safety, curtain and like pin machinery, consisting of a pair of
approaching and receding tools, with one of the said tools working through the

page_text: blanks in the hopper and adapted to extract the said blanks therefrom one at a time,
and to approach or nearly meet the other and clamping tool prior to the said blauk
being carried to the coiling head--tock or such-like fashioning device, substantially
as described and set forth.
Secondly. In a feed for safety, curtain and like in machinery, the combination
with the approaching and reciding or ascending and descending tools with the
bottom tool passing through the pile of blanks in the hopper, of mechanism for
operating the said ascending and descending tools, substantially as described and
set forth.
Dated this 11th day of July 1896.
