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 my invention for "IMPROVEMENTS IN APPARATUS FOR THE MANUFACTURE OF
WIRE CHIEFLY DESIGNED FOR USE IN BOOT AND SHOE NAILING MACHINES" 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 apparatus for the manufacture of wire chiefly designed
for use in machines for nailing boots and shoes, which wire is composed of a central
core of waxed thread or fine cord, metal, or other material encased in a metallic
covering, cylindrical in cross section, which is bent around and made to cover the
thread completely.
:
The said apparatus consists essentially of cutting discs for dividing a ribbon of
metal into narrow strips, of guides and fingers which serve respectively to direct
the uncut ribbon to the cutters and to return the cut strips, immediately after..
passing the cutters, to the same plane in order that they may pass evenly to the
receiving spools or reels on which they are wound; and of mechanism which is
adapted to take the thread and the metallic strip which form the wire, from the
supply reels, groove or bend the flat strip into a trough shape, lay the thread in the
trough or groove, complete the bending of the wire over the thread so as to encase
it, corrugate or roughen the surface of the wire thus formed; and lay the completed
wire upon a receiving spool or reel, all as hereinafter described.
In the accompanying drawing,

Figure 11 is a section on the line x-x Figure 5 of the gear wheels which operate
the grooving and finishing rolls.
The first operation consists in dividing a ribbon of metal into narrow strips.
This is accomplished by means of the devices shown in Figures 1, 2 and 3 in
which A is a stand or table on which, by means of convenient frame work the
various parts are supported. A driving shaft B mounted in suitable bearings, see
Figure 1 is provided with a driving pulley C. On the shaft B is set a pinion D
which may be made fast with the driving pulley, when the operator desires to
start the machine, which is done by nicans of the shipper lever E and clutch
mechanism of well known construction shown in Figures 1 and 3. The pinion D
meshes with the gear wheel F, fast on the secondary shaft G which is mounted
in bearings on the arms H H. On this shaft is also mounted the receiving spool I,
which is held in position by a nut on the shaft, see Figure 1, so that it may be easily
removed when full. Directly in line with this spool and the rotary cutters J is a
spool or pin K, supported on suitable projecting arms L, which holds the coil of
metal which is to form, when cut, a series of narrow strips: Between the supply
and the receiving spools is set, in bearings in the uprights M M, a short shaft N
which is placed directly above the shaft B. This shaft B₁, is also supported in the
uprights M M, and is connected with the short shaft N, by the gear wheels O, O',
by means of which the movement of the shafts and their cutting discs is kept
uniform. On the shaft B¹, between the uprights M M is secured a series of collars r,
which are separated by collars t of less diameter placed between them on the shaft,
see Figures 1 and 3. These collars form a series of cutting discs, and the collars t
hold the cutters apart a distance corresponding to the width of strip which it is
desired to cut. A similarly prepared series of cutting discs and collars is set on the
short shaft N, and the shafts are so arranged relatively to each other, as that the
discs of each shall project slightly into and shall fit the spaces of the other:
The edges of these discs, which are of hardened steel ground to the exact size required,
are sharp, and, when the shafts N and B' are revolved, act as cutters. They are
rotary shears, and will readily divide the broad strip of sheet metal into a series of
narrow strips, equal in width to the width of the cutting discs and corresponding
spaces.
The broad strip P Figure 1 in passing from the coil is guided over a table a
Figure 2 between the guide pieces bb₁ and is thereby presented evenly to the
cutters.
The guide b is set fast on one side of the table a, and slightly outside of the
line of the cutters, so that the rough edge of the strip P will be trimmed off, thus
forming a smooth outside edge to the narrow strip cut from that side of the
ribbon P. The guide 6 is set on a pivot at b², the other end being attached to the
spiral spring 8, which acts to draw the end of the guide to which it is attached
away from the ribbon of metal P, thus forcing the end of the guide which projects,
close to the cutters against the ribbon, and holding the ribbon pressed tightly
against the other guide b'. This arrangement of the guide b allows the latter to
accommodate itself to the inequalities of the edge of the ribbon of metal which is
being cut. After passing the cutting point, the narrow strips which are formed
pass under and over the respective discs by which, they are cut and which carry
them above or below the plane on which they are cut.

page_text: In order that these strips may wind evenly on the receiving spool, I find it best
to throw them back, so that they will all lie in the same plane, and to do this I
arrange upon the rods cc set between the uprights M, M, see Figure 3 a series of
fingers d of the shape shown in Figure 2, so arranged that each space between the
cutting discs will be occupied by a finger, the point of which will bear upon the
strip immediately after it has passed the cutting disc, and press or guide it back.
into the plane of cut. The fingers which lie in the spaces between the upper
cutters, Figure 3 lie above the metal and pross the strips which are, in the
operation of cutting, forced up by the lower cutters, downward again on to the
plane of cut, while the lower fingers which act in the spaces between the lower
cutters, act reversely to press upward the strips which have been cut and carried
down by the upper cutters.
The shaft N which carries the upper cutters is mounted in common sliding
bearings which are adjusted by set screws from above in the well.known manner.
and which permit of the necessary adjustment of the cutters.
The shafts which carry the cutting discs are geared together at 00¹ in order.
that they may act uniformly and also that it may be easier to get the ribbon P
into the machine when it is started. In getting the end of the ribbon P between
the cutters before starting a crank is applied at A¹², Figure 1.
The shafts bearing the cutters have no power applied to them, the operation of
cutting, being accomplished by drawing the ribbon of metal through between the
cutters, which is done by spool I. This spool, having the cut strips secured to it,
is keyed fast to its shaft G, and the revolution of the shaft draws the metal strips
between the cutters.
It is obvious that the devices described may be employed for stripping other
materials besides metal, and are particularly efficient where the material is hard to
cut, or must be cut evenly.
A. reel after having been filled with narrow strips of metal as described is
mounted upon the arms a Figure 4.
The metallic strip from the reel passes from it between the grooving
rolls ff, provided respectively with concave and convex peripheries which
act upon the flat strip, as it passes between them, and groove or form it into a
trough shape, whence it passes through the guide g* formed to receive it and into
which the waxed thread from the reel d* on the arm 6* also passes (see
Figure 4). As the thread g¹* passes into the guide g*, it is laid into the groove or
trough in the metallic strip, and the strip and the thread in this relation pass
between the concave peripheries of the finishing rolls h* h¹ which finish the
bending of the strip and press it into a tube or cylinder, around the thread.
:
The peg wire is then completed but has not been corrugated. The wire C* then
passes as shown in Figure 4 over sheaves so arranged as to bring it into position
to be passed through the corrugating spindle. This spindle is arranged to
revolve, and is provided on top with a hard metal corrugating tool k*, provided*
with a toothed cutting-edge, and so set (see Figures 6 and 10), with relation to the
wire, which passes up through the hole k in the centre of the spindle, as to bear
upon the wire while the spindle revolves and thus cut a spiral groove or series of
grooves in its surface, leaving it roughened or corrugated. The set screws k™*, **,
Figure 6, and 10 suitably secured to the top of the spindle serve to keep the
finger in a given position, and permit of its.adjustment relatively to the wire.
After passing the corrugator the wire C* passes through a hole *, in the guide.
rod m*, (see Figure 8), and is laid on the receiving reel E*. The purpose of the.
guide rod m is to lay the wire evenly on the reel, and to do this, it is necessary
that it should reciprocate horizontally, carrying the wire with it, and causing it to
cross and re-cross the drum of the reel. To obtain this movement of the guide,.
I provide the following mechanism more fully shown in Figures 8 and 9. On the
shaft F*, which is mounted in a suitable supporting frame G I secure a bevelled
gear wheel * arranged to mesh with another bevelled gear wheely, fast to the
upright shaft H*, which is mounted in supports in the frame. On this shaft is set

the
the worm I,, which meshes with the gear wheel. J* fast on shaft K*, on which
shaft is also secured the driver L*, provided with a cam path n* cut in its
periphery. A traveller 2* is secured to two rods * and m* which slide
frame pieces G*, and is provided with a pin o* which runs in the cam path n*,
thus causing the traveller p*, the rod **, and the guide rod m* to reciprocate as
the cam revolves. As the guide m* reciprocates it lays the strand of peg wire
evenly in the coil on the reel E*. The reel has a conical drum so that the coil of
wire may be easily slipped off, and has a removable head M* which may be.
removed when it is necessary to empty the reel. The slits 8*, (see Figure 9) in
the heads of the reel enable the operator to tie the coil of wire before removing it.
The driving shaft P* (see Figures 4 and 5) is provided with a driving pulley R*,
and power is conveyed from the shaft through pulley R! to pulley R** which is
fast with pulley R³* which in turn is connected by a belt to pulley R***which
drives shaft F1* Shaft Fi* is provided with a gear wheel H¹* which meshes with
pinion H on small shaft F**. This shaft is provided with a grooved pulley a¹*
which is connected by a belt to the grooved pulley a* on the spindle * and thus
motion is communicated to the corrugating mechanism (see Figures 4 and 6).
The main driving shaft P is provided with a small gear wheel 61* which
actuates the pairs of gear wheels 62* and 63* which drive respectively, the grooving
and finishing rolls (see Figures 5 and 11). As the grooving and finishing rolls
wear, they may require adjustment relatively to each other, and, for other reasons,
it is desirable to be able to adjust them. In order that I may do this I mount one.
of each of said rolls f¹* and h¹* in the blocks f** and ** respectively. These
blocks are dovetailed to projecting parts of the supporting frame, as shown at w*
Figure 5, and are provided with adjusting screws w₁* tapped through and into the
frame, and by means of which rolls f¹ and h¹* may be set toward or from their
companion rolls f* and h* (see Figure 4).
The supply reel c* may also be adjusted, horizontally, by means of the dovetail
shown at a Figure 4 in its supporting frame.. This adjustment of the reel is
necessary in order that as it is used it may be shifted by the operator so as to
bring the next coil in line, it being necessary for the even paying off of the metal
strip that the coil be substantially in line with the rolls, as will be obvious.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign Correspondent I declare that what I claim is
