page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 machines for making wire nails.
Wire nail machines heretofore in use have generally been made with recipro-
cating dies, and the operative parts have ordinarily had a variety of intermittent
or stop motions, so that the capacity of the machine has been comparatively limited,
thus making the cost of manufacture very considerable, especially in the small sizes of
nails or brads.
The object of my invention is to produce a wire nail machine of a simple, durable,
efficient and cheap construction, the dies or operative parts of which have no inter-
mittent, reciprocating or stop motions, and which may therefore be run at great speed
and have a correspondingly great capacity, so that even the smallest sizes of nails may
be manufactured at slight cost.
To this end my invention consists in one or more pair of continuously revolving
clamping dies arranged parallel to the axes on which they revolve, and registering
together as they pass the line joining their centers of rotation, so as, at this point, to
firmly clamp and hold the blank from which the nail is to be made during the heading
and pointing operations. It also consists in one or more pair of revolving pointing
dies mounted at one end of the clamping dies and concentric therewith, and preferably
mounted upon the same rotary carrier or disk as the clamping dies, so that the
pointing will be effected simultaneously with the clamping of the nail and by the same
movement. The pointing dies may be formed integral with the clamping dies, but it
is preferable to make them of separate pieces of steel because of their greater liability

page_text: to wear, and consequent need for more frequent. removal and replacement, and also
for convenience of adjustment. It also consists in conjunction with the revolving
clamping dies of a rotary heading tool or die, revolving continuously like the clamping
dies and with an approximately equal surface speed, its axis being transverse to the
axes of the clamping dies and arranged and adapted to strike or act directly upon the
projecting end of the nail blank or upon an interposed swaging block or die at
the instant said blank is firmly held or compressed between the clamping dies. It
also consists in conjunction with the revolving clamping dies, and the continuously
revolving rotary heading tool or hammer, of an interposed continuously revolving
swaging block or die. This interposed swaging die is preferably carried upon one of
the revolving clamping dies, or its disk or carrier, and is driven upon the nail head by
the rotary heading tool. Where a number of clamping dies are mounted upon each
rotary disk or carrier one of these swaging blocks should be employed for each pair of
dies. By the addition of these interposed head swaging blocks I am enabled to give
the head any desired configuration or size. And they are specially servicable in
overcoming the tendency of the rotary heading tool when acting directly upon the
projecting end of the nail blank to incline the same, especially where considerable
stock is to be put into the head. It also consists, in conjunction with the continuously
revolving clamping dies, of the wire feed device, preferably a simple pair of revolving
feed rollers, for feeding the wire, from which the nail blanks are cut, across the path
of one of the revolving clamping dies, or across the face or periphery of the disk or
rotary carrier to which the die is secured. It also consists, in conjunction with said
clamping dies and wire feed, of a rotary cutter or knife revolving continuously like
the clamping dies and arranged about tangentially to the path of said dies, and at the
same or about the same surface speed, said knife operating in conjunction with an
opposing stationary knife. It also consists in conjunction with said wire feed device
and said revolving clamping dies of a fixed stop for the end of the wire to abut against
as it is fed forward across the path of said die, so as to insure the nail blanks all being
exactly the desired length. It also consists in conjunction with this stop, of a feed
device operated or geared to feed the wire faster than required and adapted to slip
after the end of the wire strikes against this measure or stop. By this means just the
required length of wire is certain to be fed for each blank and no more, as the extent of
feed in no way depends upon the timing or accurate speeding of the feed device or of
its firmness of grip upon the wire, the only condition required, within reasonable
limits, being that the feed be fast enough. It also consists, in conjunction with the
revolving clamping dies, of a shoe or curved guard concentric with the path of one of
said dies and extending from the feed point to near the point where the two dies come
together, for the purpose of holding the nail blank after it is severed from the wire in
or upon said die, and thus causing said blank to be carried by said die between such
die and its opposing die. It also consists in providing this shoe or guard with a
spring or yielding pressure device for the purpose of better holding the nail blank in
or upon the die. It also consists, in conjunction with the revolving die and said shoe
or guard, of a drag spring or yielding straightening device projecting across the path
of the nail blank as it is carried in or upon said die; for the purpose of pulling,
arranging or straightening the blank in the die, in case it should not lie straight or
properly therein as the die passes. It also consists, in conjunction with said shoe or
curved guard and the revolving clamping, die which carries the blank, in providing
the opposite clamping die with a peripheral groove or recess for the extrenie end of
this shoe or curved guard to extend into, so that the shoe may extend down between
the opposing dies as they come together in their circular paths sufficiently to hold the
blank securely in place until it is grasped between the opposing dies. It also consists
in so grinding or shaping the opposing clamping and pointing dies, especially the latter,
that their peripheral faces or cheeks which roll together are slightly higher, (that is,
farther from the centre of rotation,) than the cutting edges of said dies, so that while
said opposing cutting edges may come so closely together as to completely sever the
wire and point the nail, they nevertheless cannot quite touch; by this means the
cutting edges of the opposing dies as they revolve together are prevented from

page_text: invention also consists in the novel devices and novel combinations of devices herein
shown and described and more particularly pointed out in the claims.
In the accompanying drawing I have shown a machine embodying my invention,
and said machine constitutes what I believe to be the best way now known to me of
practicing the same, not only in point of speed and efficiency of operation, but also in
points of durability, simplicity and cheapness of construction, ease of adjustment, etc..
And while this best and most perfect form of my invention known to me involves
all or nearly all the several features of the invention hereinbefore in part enumerated
and hereinafter more particularly pointed out in the different claims, it should
however be observed that many of the principal features of my invention may
separately be employed or embodied in machines without the others.

In said drawing A represents the frame of the machine which should be of a strong
and unyielding construction. B and C are a pair of opposing rotary die carriers,
preferably solid disks or wheels, revolving together. These disks should be made of
steel and their shafts, B and C are preferably cast integral with them to prevent any
possibility of the die carrier disks moving on their shafts and thus getting out of
adjustment. For convenience of mounting and adjusting the dies on the periphery of
these disks or die carriers, I provide each of said disks with an annular groove bc,
thus forming an annular peripheral rim, and in radial slots or recesses 62 c2 cut in

page_text: these rims the clamping dies D D and the pointing dies E E are mounted or secured.
Any desired number of dies may be mounted on each wheel or disk. In the machine
shown in the drawing five pairs of dies are employed. The clamping dies are all alike,
excepting that those on the disk B complement and counter the opposing ones on the
disk C. Each of these dies consist of or are provided with a half-round groove or
other shaped receptacle d conforming in shape to the blank to be clamped between
them: Each of the opposing dies also preferably has a projecting ledge d³, con-
stituting one side or wall of the groove d. The ledge d' has a peripheral or curved
face which is or should be concentric with the periphery of the disks B, C. The
face d' of the die D on the other or opposite side of the grooved is ground on a
curve of the same or about the same radius as the disks B, C, and concentric or about
concentric thereto. The projecting ledges on the opposing dies D D of the
disks B, C, of course counter each other, as indicated in figures 15 and 20. The
projecting ledges d' of the dies, which are mounted on disk B, serve to carry or force
the nail blank a after it is severed from the wire a¹ around under the curved shoe or
guard F until it meets and is clamped by the opposing die D on the disk C. The
dies D D are secured in place in their slots or seats in the disks or carriers B C by
means of threaded bolts or screws d and d. The die D consists simply of a
rectangular block of steel, and its end rests upon the threaded bolt or screw d', which
has a polyginal or angular head de for the reception of a wrench to adjust the position
of the die radially. The head of the screw or holt d fits against the beveled edge or
corner d' of the die D, and serves to secure the die D transversely. The opposing
pointing dies EE are also of a similar construction to each other, each preferably
consists of a half conical or half pyramidal groove e, continuing the half cylindrical
groove of the clamping dies, and two similar oppositely turned grooves el e¹, one on
each side of the groove e, thus forming the V shaped cutting edges e² e² of the pointing
die, as shown in figures 8 and 9. The peripheral faces et e of the dies E E, on each
side of the V shaped cutting edges e²e, are slightly higher or ground on a curve
having a slightly larger radius than the curve described by said cutting edges, so that
the opposing dies E E abutting against their peripheral faces ee will prevent their
cutting edges e² ² from touching or striking against each other and thus becoming
worn or injured. These abutting faces et et are however only very slightly higher
than the cutting edges e² e², so that said cutting edges will nevertheless come
sufficiently close together to completely sever the wire and point the nail, or leave
such an extremely thin fin that it will readily tumble off and produce a clean cut point.
The pointing dies E E are secured in the same radial slots in the disks B, C, as
the clamping dies D, D, and the same screw d³ serves to hold the pointing die in place
transversely the pointing die being in fact clamped between the clamping die D and
the back wall of the slot 2 or c². The inner end of the pointing die E rests upon,
and the die is adjusted radially by, a wedge e that fits and slides in a groove or
recess b³ ³ in the disks B, C. This wedge is held in place by a clamp-screw e which
passes through a slot e' in said wedge. As the dies E roll together in peripheral
paths, their cutting edges have somewhat of a shearing action, and hence operate much
more easily both in respect to the power required and wear upen the dies themselves,
than where the dies are made to approach each other on a direct line, as is the case
with reciprocating dies, and in my revolving dies one of the cutting edges e² e²
in part at least, slightly in advance of the other, and, as the work is done at the very
operates,
instant the opposing dies approach their common diametrical line they have a kind of
knee-joint or toggle-lever action so that the machine acts very powerfully, and easily
exerts a very great pressure. The clamping dies of course have this same action and
hence are easily made to clamp the nail blank with great pressure at the instant the
heading die operates.
The wire a is fed across the circular path of the dies D, E, on the wheel or disk B,
or across the peripheral face of said disk, by a pair of continuously revolving grooved
feed-wheels or rollers G, G¹. The upper feed-wheel G or its shaft is journaled on a
frame or arm g secured to the frame of the machine and the lower roller G³ or its
shaft is journaled on an eccentric sleeve which turns in suitable bearings in the

page_text: arm or bracket. This eccentric sleeve is provided with a projecting arm or
lever g³ to which a spring or weight g is applied for the purpose of pressing the feed
rollers G G together with sufficient force to grip and feed the wire. A lever g
connected to the arm g3 by a link g serves to move the lower feed roller out of contact
with its companion and thus stop the feed when desired. And when the lever is
raised into the position indicated in dotted lines in figure 11, it will so remain, the
center being passed.
The wire a is continuously fed forward by these feed rollers until the end of the
same strikes and abuts against a fixed stop or guage H, which, projects across the
periphery of the disk B. This stop or guage is secured to the frame of the machine
or a suitable bracket thereon, and is adjustably fixed in place by a set-screw / or other
suitable device.
The curved guard or shoe F is provided with guide pins or studs which fit in
suitable holes in a bracket F" secured to the stationary frame of the machine and
which overhangs the disk B. A spring serves to press this curved guard or shoe
against the periphery of the disk B or against the nail blank a carried thereon. The
heads of the guide pins ff serve to limit the space between this shoe and the periphery
of the disk B. The shoe F should be comparatively narrow in relation to the length
of the nail blank, and the disk or carrier C should be provided with a peripheral
channel or groove for the lower end of this shoe to fit in, so that the shoe may
extend down far enough to hold the nail blank in place until it is clamped between the
opposing dies. And for the same reason and purpose the clamping dies B on the
disk C are furnished with a similar groove or notch..
.
K is a rotary cutter or knife mounted on the enlarged end or head K' of the cutter
shaft K². This head K is preferably furnished with two knives K, though a greater
or less number may be employed as desired. The axis of the rotary cutter is or should
be parallel to the axes of the revolving clamping dies or their carriers B, C, so that
the cutters K will revolve in a plane at right angles to the wire a'. I is an opposing
stationary knife mounted on the frame of the machine and across the edge of which
the wire a is fed. The circular path of the rotary knives K K is, or should be about
tangential to the path of the clamping die D on the disk B, and these rotary cutters
have, or should have, the same, or about the same, surface speed as said dies. In this
way or by this means the rotary cutters as they strike the wire and sever and carry
the nail blank past the edge of the stationary knife I, will not tend to disturb the
transverse position of the blank on the periphery of the disk B, or rather its longi-
tudinal position in the clamping die thereon. The knives K K fit in suitable slots or
grooves cut in the end face of the head K' or in the clamping disk k² by which the
Knives are clamped or held in place. Screws or threaded bolts serve to firmly clamp
the plate or disk against the knives. The knives are readily adjusted by simply
loosening the screws and driving on the ends of the knives with a punch and
hammer. The cutting edge of the knives should preferably be curved about as shown
in figure 15.
L represents a drag-spring or yielding device for ensuring the proper positioning
of the nail blank against the projecting ledge d² of the die D after it is severed from
the wire. This nail blank arranging device L preferably consists of a forked or slotted
spring as shown in figure 23, the lower forked ends of which fit astride the shoe or
curved guide F. As the nail blank is carried forward under the shoe by the projecting
ledge of the die, if for any cause the blank should not happen to lie perfectly
straight in the die, this forked spring L will draw the blank snugly into the die as the
blank and die pass under the spring. The lower or operating end of this spring
should be located just in front of the place where the wire is fed across the periphery
of the disk B.
Nis the rotary heading die or tool. It is mounted in a suitable slot or hole n in
the shaft N¹, and consists preferably of a round block of steel. It is secured in its
shaft by a wedge n, and a pair of set screws n² n³, one of which, n², serves to tighten
the die in place, and the other, 73, to adjust it radially in or out from the center of its
shaft by moving the interposed wedge n' at the end of the tool. The heading die
2

page_text: shaft N is made adjustable in two directions, that is to say its box or bearing N² is
adjustable vertically by suitable screws * and to or from the end face of the die
wheels B C, by screws or other suitable means. The purpose of these three adjust-
ments is not only to regulate the shape and degree of flatness of the head formed
upon the nail by the die, but also to properly center the head on the nail or upon the
interposed swaging block or die N³.
The swaging blocks or dies N³, one for each pair of dies D, are mounted upon a
suitable ring or projecting flange C secured to the disk C in such position that the
outer rim of said ring will project over the outstanding end of the nail blank. This
ring C is removably bolted or screwed to the disk C, and is provided with an annular
shoulder or offset which fits against the face of the disk C so that an annular space
may be left between the rim of the ring and the face of the disk or the dies equal to
or greater than the length of the projecting end of the nail blank. The swaging
blocks or dies N³ are mounted in suitable holes furnished with steel bushings N
These holes are so arranged that the swaging blocks register centrally with the
dies D, D. The outer end of these blocks or dies N3 against which the heading tool
end strikes should be slightly rounded, as indicated in figure 19, and the inner end
may be cupped or given any desired configuration to form the style of the head
desired.
After the head has been formed upon the nail each block or die N³ is returned to
position by a stationary cam N³ secured to the frame of the machine in the circular
path of said block or die, and which forces it out ready to strike the nail head.
A stationary curved guard No serves to hold the swaging blocks in their places while
the machine is in motion.
As the swaging blocks or dies N³ are carried on the disk C and consequently have
the same path and rotary movement as the dies D, D, and nail blank clamped between
them, and as the end wise movement of the blocks or dies N³ is directly in line with
the length of the nail they strike a true blow and will form a perfect head upon the
nail of any desired shape.
The heading tool N should be so timed and located in relation to the clamping
dies D that it will not strike the interposed die or block N until the nail blank has
been firmly seized or clamped between. the dies D, D. And ordinarily I so adjust the
heading tool shaft N' that its center is somewhat below the diametrical line joining
the centers of the disks B, C, so that the interposed die block will not be struck
until the dies D D and the nail therein almost arrive at this diametrical line.
In that modification of the machine wherein the interposed swaging blocks or
dies N are not employed, as illustrated in figures 25 to 30 inclusive, and wherein the
rotary heading tool acts directly upon the projecting end of the nail blank the face of
the die of course approaches the projecting end a² of the nail blank in a curved path
and it is consequently somewhat inclined when it first strikes said projecting end, and
would thus have a tendency to slightly wipe or incline the head upwards. This
tendency is however very easily counteracted by slightly increasing the surface speed
of the heading die, so that the speed of the die shall be slightly in excess of that of
the nail blank. The surface speed of the face of the heading die may be regulated
by simply adjusting the die N radially in or out and thus increasing or diminishing
the radius of the circle in which it travels. Any radial adjustment of the die would
however affect the shape or degree of flatness of the head of the nail unless such
radial adjustment was compensated for by a corresponding bodily adjustment of the
header shaft to or from the disks B, C. By means of the three adjustinents before
referred to however the head of the nail may be made of any desired form and still be
formed centrally upon the nail. If desired also the heads may be uniformly made
more or less to one side of the nail by a simple adjustment of the header die and its
shaft. Where the heading die acts directly it tends to prevent the die from slipping
on the end of the nail blank to serrate or roughen the face of the die.
The header shaft N' should in any construction be sufficiently long to give room
for a firm and secure bearing upon the frame of the machine. It is furnished with a
band wheel M and a fly-wheel M. A bevel gear 0 upon this shaft transmits

page_text: through the bevel gear o on the counter shaft and a spur gear o² thereon, motion to
the shaft. B' of the disk B by means of a spur gear o³ which meshes with the spur
gear o on the counter shaft o¹. Motion is communicated to the opposite shaft C² of
the disk by means of a spur-gear o on the shaft B which meshes with a spur
gear on the shaft C'. This spur gear o is or should be provided with a split
part of secured to the part of by bolts o' which pass through slots in the split gear
parts of so that by slightly turning or adjusting the part of on the part o³ all wear
between the teeth of the gears o' and 0, 0, is taken up. This is a matter of great
convenience in keeping the dies on the disks B, C, in proper register with each other.
The split gear of fits on the hub os of the gear o. The hub of this gear o³ is secured
on the shaft C by adjustable keys o, o which fit in oblique inclined grooves in the
shaft C, and corresponding straight grooves in the hub of the gear, so that by
driving one wedge or the other the gear may be turned or adjusted in one direction
or the other on the shaft, for the purpose of bringing the dies on the disk B, C, in
proper register with each other. The shaft B of the disk B, is mounted in fixed
bearings on the frame of the machine, but the box or bearing C2 of the shaft C³ is
made adjustable horizontally by means of threaded bolts C³ ³ for the purpose of
adjusting the disk (to or from the disk B and thus regulating the degree of pressure
between said disks and the opposing dies thereon.
The shaft of the upper feed wheel or roller G is provided with a driving pulley ór
band wheel G, by which the feed wheels are driven. The lower feed wheel is or may
be driven in the ordinary manner by a gear on its shaft meshing with a gear on the
shaft of the companion wheel. The band wheel G' may preferably take its motion
independently from the counter shaft or source of power, from which the band
wheel M is driven. The size of the pulley G is such in relation to the size of the
feed wheels, the length of the nail blank, and the speed of the disks B, C, and number
of dies thereon, that the wire will be fed somewhat faster than required, so that the
end of the wire will be sure to strike against the stop or guage H before the rotary
knife severs the nail blank from the wire. But little power is required to drive the.
feed wheels G G¹, and the belt G3 which operates the pulley G, should fit loose
enough to slip readily upon the wheel the moment the forward feed of the wire is
arrested by its striking against the stop H; or the feed wheels G G may be adapted
to slip upon the wire when the further feed of the same is arrested by the stop H.
By this means no complicated feeding mechanism is required, nor accurate timing or
speeding, in order to insure the requisite length of feed for each nail blank, and all
the nail blanks will be cut of absolutely the same length. The rotary knife shaft is
driven by a gear & thereon, which meshes with the gear o on the shaft B'.
In order to oppose the thrust of the heading operation, I provide a double cone
hearing roller Rapplied to the back of the disks, inclining the surface of the disks
and roll so that they will correspond in surface speed. This avoids the strain and
racking to which the disks might otherwise he subject, and affords a bearing that in
no wise interferes with the free and rapid movement of the disks. To compensate
wear and also to furnish adjustment, the double cone roll may be journaled in a
frame R adjustable on the main frame of the machine by slotted bolt holes or
otherwise.
In case the rotary heading tool N is employed in such manner as to come in direct
contact with the head of the nail blank without the interposed swage or block N³ thie
former may be preferably roughened or serrated to prevent it from slipping on the
blank, more especially if a long portion of stock is to be flattened into a head.
