Improvements in the Manufacture of Sharp Pencil Pointed Nails,
Tacks, and Wires for Various Purposes, and in Machinery
therefor.
We, EREDERICK WILLIAM GORSE, of Stanmore Road, Edgbaston, Birmingham,
Warwickshire, Manufacturer, and ALFRED GORSE, of 283, Burbury Street,
Lozells, Birmingham, aforesaid, Machinist, do hereby declare the nature of
this invention to be as follows:-
This invention has reference firstly to the manufacture of round or sharp pencil
pointed nails tacks and wires for making staples and for various other purposes and
secondly to machinery therefor.
According to this invention we point the said nails or wires by a series of cutting
operations each performed by a separate revolving tool or tools so arranged that
the first tool starts the point by cutting a little off the end of the nail tack or wire.
the next cuts a little more off and advances the point another stage, and so on
through the series each tool cutting off a little more than the preceding until the
desired point has been obtained.
During the said cutting operations the nails, tacks, or wires are firmly held and
between each operation they are moved to the next tool so that whilst the first nail,
tack, or wire in the series is receiving the first cut, the last is receiving the finishing
cut thus completing a point every time the nails, tacks, or wires are moved through
one stage.
The machinery which we employ for carrying out the above described improved
method of pointing nails tacks and wires for various purposes may be arranged in
various ways such for instance as the following
We provide a series of revolving spindles arranged in a line side by side at equal
distances apart and suitably supported in bearings which will permit of endwise
movement of the spindles. The front end of each of these spindles carries a
cutting tool and holder adapted to support and cut the end of the nail tack or wire
when pressed against the same as hereinafter described. The said holder and
cutting tool which we prefer to employ consist of two square or other steel bars
bolted to a head on the said spindle and inclined towards each other and to the
centre of the spindle. The end of one of these bars is bent to an angle and formed
as an eye to support the nail, tack, or wire and the end of the other bar or tool is
ground or filed to a suitable angle for cutting the end of the nail, tack or wire to
the desired point when pressed against the same as hereinafter described. Opposite
the front of each spindle is a fixed holder which may consist of a pair of gripping
jaws adapted to hold a nail, tack or wire with its end which is to be pointed towards
the corresponding cutting tool. One of these jaws is or may be stationary and the
other moveable and operated by a cam or otherwise so as to release or hold the nail,
tack or wire at the proper time as hereinafter described.
Moving to and fro from one pair of gripping jaws to the next are fingers or grippers
adapted to automatically hold and carry a nail, tack, or wire and to automatically
release and deposit the same at the proper times. These grippers are or may be
carried by a bar which moves to and fro across the gripping jaws and is furnished
with cams for operating the grippers.
We find that four sets of cutting tools and corresponding gripping jaws and
moving fingers are generally sufficient but we do not limit ourselves to any particular
number as that depends upon the shape of the point and the size of wire which is
haine anomoted unan

page_text: We will describe the operation of the machine above described provided with
four sets of tools applied to pointing a-nail.
When the machine above described is at work a nail is held in each of the four
gripping jaws and the revolving cutters advance and cut a small portion off the
point of each. The revolving cutters then retire and the moving fingers are
depressed and take hold of the nails which are then released by the gripping jaws.
The moving fingers then move the nails to the next jaws respectively where they
are held and operated upon so as to reduce their points. another stage, that is to say,
a fresh blank is carried to the first gripping jaws, the nail from the first gripping
jaws is carried to the second, that from the second to the third, that from the third
to the fourth and that from the fourth is dropped finished into a suitable
receptacle.
Instead of arranging for the nails tacks or wires to move in a line as above
described they may be arranged to move around a circle the revolving spindles
being arranged in a circle either parallel with each other or radiating towards the
centre of the said circle.

Improvements in the Manufacture of Sharp Pencil Pointed Nails,
Tacks, and Wires for Various Purposes, and in Machinery
therefor.
We, FREDERICK WILLIAM GORSE, of Stanmore Road, Edgbaston, Birmingham,
Warwickshire, Manufacturer, and ALFRED GORSE, of 283, Burbury Street,
Lozells, Birmingham, aforesaid, Machinist, 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 reference firstly to the manufacture of round or sharp pencil
pointed nails tacks and wires for making staples and for various other purposes and
secondly to machinery therefor.
According to this invention we point the said nails or wires by a series of cutting
operations each performed by a separate revolving tool or tools so arranged that the
first tool starts the point by cutting a little off the end of the nail tack or wire, the
next turns a little more off and advances the point another stage, and so on through
the series each tool cutting off a little more than the preceding until the desired
point has been obtained. During the said cutting operations the nails, tacks, or
wires are firmly held and between each operation they are moved to the next tool
so that whilst the first nail, tack, or wire in the series is receiving the first cut, the
last is receiving the finishing cut thus completing a point every time the nails, tacks,
or wires are moved through one stage.
When our invention is used for pointing wire nails or wire tacks it can very con-
veniently be arranged adjacent to or to form part of an ordinary machine by which
the nails or tacks are headed and cut off from the length of wire.
On the accompanying drawings
Fig. 1 represents a wize nail blank and
Figs. 2, 3, 4 and 5 shew successive stages in the formation of the sharp pencil
point by our invention;
Fig. 6 represents in plan part of an ordinary wire nail or wire tack heading and
cutting off machine with our invention applied ;
Fig. 7 is a side elevation of same;
Figs. 8, 9 and 10 are part front elevations illustrating the operations of our
invention;

page_text: Figs. 11 and 12 are part sectional side elevations of the same;
Figs. 14 and 15 represent in side and front elevations respectively details of the
same, and
Figs. 16, 17, and 18 illustrate one of the revolving cutting tools and holders of
the same on an enlarged scale.
The said wire nail or wire tack heading and cutting off machine partly shewn in
Fig. 6 is of the ordinary kind and as it forms no part of this invention and is of a
kind well known it requires no description here further than to state that A is the
continuous length of wire from which the wire nail or wire tack blanks are formed,.
B is the header and C1 C2 are the two side cutting off tools which are shaped so as
to cut off the headed tack or nail D quite blunt at that end which is to form the.
point as shewn in Fig. 1. The grip lever and moving gripping tool (not shewn on
the drawing) are made to work underneath the tool box so as to be out of the way
of the moving fingers of our invention.
In carrying out our invention we provide a series (say four) revolving spindles El
E2 E3 E arranged in a line side by side at equal distances apart and supported in
the bearings which will permit of endwise movement of the spindles. These
spindles receive rapid rotary motion by belts from the pulley G¹ on the shaft G2
which is driven by a belt from the pulley G³ on the shaft G, or the spindles may
be driven in any other convenient manner. The front end of each of these spindles
carries a cutting tool H' and holder H2 (shewn on an enlarged scale by Figs. 16,
17 and 18) adapted to support and cut the end of the nail or tack when pressed
against the same as hereinafter described. Each of the cutting tools Hand
holders H² is by preference made of a square or rectangular section steel bar
bolted to a head e¹ formed on the spindle and made with inclined sides as shewn
so that the cutting tool H and holder H2 fixed thereto will incline towards each
other and to the centre line of the spindle. The front end of the holder H² is
bent to an angle as shewn and formed as an eye h¹ to support the nail or tack whilst
the point is being turned thereon by the cutting tool H the front end h² of which
is ground or filed to the proper angle (as shewn) for cutting and pointing the end
of the nail or tack when pressed against the same as hereinafter described.
Opposite the front end of each of the revolving spindles E¹, E, E³, E, is a fixed
holder consisting of a pair of gripping jaws marked 11 12 made of a V shape or
otherwise formed so as to hold a nail or tack between them with its end which is to
be pointed towards the corresponding cutting tool H₁ and holder H2. The lower
jaws are stationary being bolted to the frame J which supports the various parts
of the machine, and the upper jaws I2 are movable and operated indirectly by the
cams 13 on the revolving shaft K from which shaft the movements of the various
other parts of the machine hereinafter described are obtained. Each of the upper
jaws 12 forms part of a lever I free to turn about a fulcrum 15 at its lower end (sec
Figs. 11 and 12) and pulled back by the spring 16 against a set screw 17 on the
slide 1 which latter is moved forward by one arm of the two armed lever I the
other arm of which rests upon its operating cam 13 which latter is of circular form
with a cut away part as shewn in Fig. 11. The slides 18 are each pulled back by a
spring I connected to a bar I-at the back of the machine. It will be seen that
each of the upper jaws 12 are closed down upon their corresponding lower jaws to
hold the nail or tack (at the proper times as hereinafter described) when, as shewn in
Fig. 11, the high part of the cam 13 lifts the lever 1° and moves forward the slide I* ;
and when, as shewn by Fig. 11, the cutaway part of the cam 13 comes opposite to
the lever I', the jaw 12 and slide 18 are drawn back by the springs 1º.
We obtain the said backward and forward motion of the spindles E¹ E2 E³ E¹
in the bearings (at the proper times as hereinafter described) from the cam E³ on
the revolving shaft K (see Figs. 6 and 7) which operates the two armed cranked
lever E which turns on a fulcrum pin E' and is kept pressed against the cam E³ by
the spring Es. The upright arm of this lever E' is connected by the adjustable
link E to the two armed lever E10 which can turn about its fulcrum pin E". The
shorter arm of this lever E10 is jointed to one end of a bar E" which crosses the

page_text: spindles E E E E underneath and rests upon the frame or bed J on which it can
slide. Near the other end of the bar E¹ there is another lever E³ parallel to and
of the same length as the shorter arm of the lever E so that this bar E12 has a
parallel motion at right angles to the said spindles. On the bar E under each of
the said spindles there is a projection E which engages between collars e² e³ on the
said spindles and compels the spindles to move to and fro with the bar E¹. It will be
seen that the high part of the cam E' gives the forward movement to the said
spindles and that their backward movement is obtained by the spring E8 when the
end of the lever E falls into the cut away part of the cam E³.
Moving to and fro from one pair of gripping tools to the next are fingers or grippers
adapted and arranged to automatically hold and carry a nail or tack and to auto-
matically deposit and release the same at the proper times. These pairs of grippers
are marked L L L L and they are carried by the bar M¹ which moves to and fro
in the bearings N1 N2 across the gripping jaws I' 12 and is furnished with cams for
operating the said fingers or grippers. Each pair of fingers or grippers consists of
two fingers 12 jointed at 13 to the bar M. The lower ends of these fingers are
notched as shewn so as to hold the wire nail or tack between them when pressed
together by the wedge being forced between the upper ends of their fingers as
shewn in Figs. 9 and 10. This wedge can slide up and down in the boss its
downward motion being obtained by the lever 16 which is jointed at 17 to the
bracket 18 fixed to the bar M', this lever 16 being operated by the cam ³ on the
shaft which latter is carried by the brackets 1, 18 and receives a partial rotary
movement at the proper times as hereinafter described by the arms o¹ o² being
struck respectively by the upwardly projecting levers which latter are
operated respectively by the cams p² q on the revolving shaft K. Coiled springs ³
press the wedges upwardly and the fingers are constantly pulled apart by the
coiled springs. The bar M' has upward and downward movements imparted to it
at the proper times as hereinafter described by the levers R R2 operated by the
cams R³ R on the revolving shaft K. The bar M¹ is continually pressed down by
tension springs R' acting through the upper levers R and the bar M' receives its
backward and forward movements by the cam S' acting through the levers S² S³
and forcing the bar M from left to right and by the spring S* which pulls the
bar M back again. S' is a stop to prevent the bar M' moving too far.
When the machine above in part described is at work a nail or tack D is
held in each of the four pairs of gripping jaws '12 and the revolving
spindles E¹ E² E³ E* carrying the cutters and holders H₁ H2 are advanced
together and turn a small portion off the point of each nail or tack. See
Figs. 6, 7, 8 and 11. The points of these four nails or tacks will then appear as
shewn respectively in Figs. 2, 3, 4 and by which it will be seen that each of
the revolving cutting tools is set a little further forward than the tool preceding
it so that the nail or tack Fig. 3 is rather more pointed than that shewn by
Fig. 2, the nail or tack Fig. 4 is rather more pointed than Fig. 3 and the nail
or tack Fig. 5 is more pointed still and finished. Whilst the cutters of the
spindles E E E E are acting as above described the bar M', which is in its
highest position as shewn by Fig. 8 with the fingers open, is moved to its extreme
left position and when the spindles E E E³ E have retired the bar M¹ and
the fingers move down and the fingers are closed together and grip the nails or
tacks (as shewn in Fig. 9) by the upright lever q¹ striking, with its downward
movement, the arm and turning the cams up under the tail ends of the
levers 1. The exact position of the bar M' and fingers is ensured by a pin m²
fixed on the bar M dropping into a slot in the plate T fixed to the
bracket N2. The fingers to the extreme left (Fig. 9) are holding the blank
(Fig. 1) which has just been headed by the header B and is being separated
from the continuous length of wire A by the side cutters C¹ C²; the next
three pairs of fingers are holding the nail or tack which has been operated
upon by the cutters of the spindles E' E2 E³ respectively. The gripping
jaws II are then opened and the nail or tack which was operated upon by the

page_text: cutter of the spindle E is knocked out of the jaws into the shoot U by the
knocker off V₁ operated by the lever V and cam V³. The bar M with
the fingers and the nails or tacks held thereby are then lifted and moved to the
right hand over the next gripping. jaws where the nails or tacks are deposited
by the bar moving down again as shewn in Figs. 10 and 12. The exact position
of the bar is ensured by the pin m³ on the bar M¹ taking into the slot 2 in
the plate T. The top jaws I then close down on to the tacks or nails and
hold them; the fingers are then opened by the lever p₁ striking the arm o¹
upwardly and turning the shaft and the cams into the position shewn by
Figs. 4, 8 and 11; the revolving spindles E¹ E' E' E' with their cutters then
advance and operate upon the nails or tacks so as to reduce their points another
stage. Thus the four nails or tacks are operated upon simultaneously one nail
or tack being finished at each revolution of the shaft K.
We find that four sets of turning tools and corresponding gripping jaws and
moving fingers are generally sufficient but we do not limit ourselves to any particular.
number as that depends upon the shape of the point and the size of wire which is
being operated upon.
Our invention can be applied to pointing split wire cutters and wires for various
purposes similarly as above described with reference to pointing nails or tacks, but,
as will be readily understood, the heading machine part is not then required.
The mechanism above described and illustrated by the accompanying drawings is
what we find to answer well in practice but it is to be understood that our invention
is not limited to the precise details illustrated.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a machine for forming pencil points on nails tacks or wires for various
purposes the combination of a series of gripping jaws adapted to hold and release
the said nails tacks or wires, a series of revolving cutting tools corresponding with
the said gripping jaws and arranged to advance and turn a portion off each of the
nails tacks or wires and then to recede therefrom, and a series of travelling fingers
corresponding with the said gripping jaws and adapted to hold the nails tacks or
wire and to move from one pair of gripping jaws to the next and back again, the
said revolving cutters, gripping jaws and fingers operating in unison in the manner
substantially as hereinbefore described.
2. The combination with a machine for forming headed nail or tack blanks from
a continuous length of wire, of the pointing machinery denoted by the first claiming
clause hereof arranged and operating in the manner substantially as hereinbefore
described.
3. The combination and arrangement of parts constituting the improved
machinery for forming pencil points on nails tacks and wires for various purposes
arranged and operating in combination in the manner herein before described and
illustrated oy the accompanying drawings.
4. The manufacture of pencil pointed nails tacks or wires for various purposes
by pointing machinery arranged and operating in the manner substantially as herein-
before described and illustrated by the accompanying drawings.
