Improvements in Machines for Making and Driving Staples, Nails,
and the like, chiefly designed for use in the Manufacture of
Boots and Shoes.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent
Agents, 45 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:-
This invention relates to machines for securing boot and shoe soles and other
articles by means of staples, which are made and driven by one and the same
machine. The invention has for its object, mainly, to provide a machine of this
class with means for perforating the stock for the reception of the staples, for
regulating the length of the staples and the depth of the holes made to receive them,
automatically, by the thickness of the sole or part into which the staples are driven,
and to generally improve the construction and mode of operation of such machines.
To these ends, the invention consists in the improvements which we will now proceed
to describe and claim.

In the drawings:
a represents the supporting-frame, which is mounted upon a standard a', and is
provided with bearings, in which the driving-shaft bis journalled. The driving-
shaft is provided with a series of cams, which give motion to the operative parts
of the machine, as hereinafter described, the said shaft being driven by power
applied through a suitable clutch, and provided with a stop-motion whereby, after a
complete rotation of the shaft, causing the feeding forward of a length of wire, the
cutting off of the wire to form the blank, the bending of said blank into a staple and
the insertion of said staple into the material, the movement of the shaft is auto-
matically stopped.
c represents the work-supporting horn, which is affixed to a horn-spindle c',
adapted to move vertically in a guide e, affixed to the standard a', the lower end of
said spindle resting upon a lever c³, which is pivoted at c to the standard a'. The
rear end of said lever is connected by a rod 6, which is preferably made in two
sections jointed at c³, with a lever c', which is pivoted at 8 to an arm co, affixed to a
rock-shaft co, the latter being mounted to turn in a bearing on the supporting-
frame, and provided with an arm e, engaging a cam c on the driving-shaft. The
forward end of the lever is connected by a link c¹ with an awl-bar or slide c¹³,
which is fitted to move vertically in guides (Figures 2 and 30), on a sliding
head d, which is mounted upon the frame a so as to move lengthwise of the driving-
shaft. represents the throat, through which the staples are driven into the stock
by means of a driver c, attached to a reciprocating driver-bar e" (Figures 28
and 29), the driver-bar being movable vertically in a slot 10 (Figure 29) in the
throat, while the driver is fitted to reciprocate in a guide formed in said throat.
The throat is fitted to slide vertically on guides (Figure 30) on the head d.
The head d slides in a fixed guide a³ (Figures 4 and 28); and is reciprocated by
means of a cam d' (Figures 3 and 4), affixed to the driving-shaft, and engaging a
trundle-roll on an arm d', affixed to said head, the reciprocating movement of the
head being such that the awls ce carried by the awl-bar c¹³, and the staple-receiving
throat c, occupy alternately the same position over the stock, so that the awls first
penetrate the stock and make holes to receive the legs of the staple when the staple-
throat is brought into position over said holes, two awls being employed, as shown
in Figures 2, 7, 8 and 9. The awl-bar, as already stated, is reciprocated by means
of a lever c and link c12.
The throat c is given a vertical reciprocating movement by means of a lever e
(Figure 4), which is pivoted at e¹ to the supporting-frame, and is connected at one
end with the said throat by means of a link e, the other end of said lever having
a trundle-roll, which is engaged with a cam e affixed to the driving-shaft. The
reciprocating motion of the throat is inuch shorter than that of the awls and driver,
and is sufficient to cause the lower end of the throat to co-operate with the
anvil hereinafter described in bending the staple blank into staple form and to
stand in position to support the upper surface of the sole against the pressure of
the horn.
The driving-bar c¹7 is reciprocated by means of a lever f (Figure 4), pivoted
at to the supporting-frame, and connected at one end by a link f' with the

page_text: driver-bar, and at its other end by a trundle-roll with a cam f³ affixed to the
driving shaft.
The links c, and f³, that communicate motion respectively to the awl-bar,
the throat and the driver-bar, are pivotally connected to said awl-bar, throat and
driver-bar, as well as to the levers which give them motion, said connection
permitting the described movement of the sliding head d, without interfering with
the operativeness of the awl-bar, throat and driver.
The wire from which the staples are made, is severed into lengths by means
of a fixed cutter h and an oscillating cutter ¹. The oscillating cutter is affixed to
a hub or holder 1, formed on or attached to a shaft or stud 2 (Figures 3 and 21),
which is journalled in a suitable bearing on the supporting-frame, and is oscillated
by means of an arm ³ affixed to said shaft, and a link (Figure 3) connecting
said arm with the lever c above described. The oscillating cutter ' is of segmental
form, as best shown in Figures 18, 19 and 20. The fixed cutter h is secured to the
supporting-frame by means of a clamp h, having a dove-tail rib h (Figures 19
and 20), engaged with a bevelled surface on the cutter, said clamp being
supported by the frame a, and adjusted by a bolt 7. The supporting-frame has
a dove-tail rib a, engaging a corresponding rib on the cutter h, the construction
being such that, by loosening the bolt, the cutter will be released, while by
tightening said bolt the cutter will be firmly held. The cutting edges of the
cutters h and are diagonally arranged with relation to the wire g, which is fed
between said cutters, the line of said cutting edges being indicated at h
(Figures 25, 26 and 27), so that the wire is severed diagonally, the ends formed by
the severing operation being there sharply pointed.
The oscillating cutter / carries a bending device, which bends the pointed end
formed on the main body of the wire sufficiently to bring the point into line with
the longitudinal centre of the wire, substantially as shown in Letters Patent of
Great Britain, No. 15,905, dated October 7, 1890. Said bending device is here
shown as a slide or bar i, which is fitted to move lengthwise in slot or guide in
the hub or holder to which the oscillating cutter is affixed. Said bender or bar
is reciprocated in its guiding slot by means of a lever ', which is pivoted at i² to
the sliding head d, and is engaged with a slot in the bar i. The lever is
provided with two arms, which are arranged so that, when the sliding head is
moving forward in the direction indicated by the arrow in Figure 18, the arm *
will be caused to strike a surface on the head d before the head has reached the
limit of its forward motion, as indicated in Figure 19, the lever being thus
engaged with the sliding head, so that it moves bodily forward and imparts a
forward movement to the bender i, thus causing the latter to bend the point of the
wire
I, this movement taking place just after the wire has been severed.
the sliding head is moved in the opposite direction, the arm i strikes a surface on
the slide before the completion of the said movement, as shown in Figure 20, so
that the arm is again locked to the sliding head, and gives the bender i a backward
movement. It will be observed that, when both of the arms are out of contact
with the sliding head, the arm ¹ is free to turn on its pivot, so that, during the
first part of each movement of the sliding head, the arm i will be arrested and
Hence there is no
prevented from moving bodily forward by the bender i.
movement of the bender until the arm i¹ has been locked or made rigid with the
sliding head, by contact of one of its arms with said head, as above described.
When
(Figures 10, 15, 24 and 25) represents the anvil, over which each length of
wire severed by the cutters is bent to form a staple. Said anvil is provided
with a blank-holding spring or spring finger (Figures 4 and 24), having a recess j³
at its free end, into which the wire is forced by the wire-feeding mechanism herein-
after described, the wire being inserted in said recess and held by the spring in
engagement with the anvil before the cutting-off operation. The anvil is pivoted
at (Figures 15 and 25), to a block or slide 1, which is fitted to move freely in a
slot, formed in a disk, which is adapted to rotate on a fixed centre or stud j³.
The rotary disk, and slide constitute a means for varying the position of the

page_text: fulcrum or pivot of the anvil laterally and thus moving the anvil toward or from
the cutters, for the purpose of decreasing or increasing the length of wire projected
across the anvil and thus varying the length of one of the staple, a rotary
movement of the disk in the direction indicated by the arrow in Figure 25
causing the anvil to move toward the cutters, while a rotary movement of said
disk in the opposite direction causes the anvil to move away from said cutters, as
shown in Figure 15.
We have provided automatic means for connecting the disk with the work-
supporting anvil, so that the position of said disk, and therefore the distance of
the anvil from the cutters, will be determined by the position of the anvil, said
means being preferably as follows: The under side of the disk is provided with a
bevel gear segment, shown in dotted lines in Figures 15 and 25. With said
segment meshes another bevel gear segment 10, affixed to a shaft, which is
journalled in a bearing in the supporting-frame, and is provided with an arm ja
(Figures 1, 2 and 3), which is connected by a rod with the lever supporting
the horn spindle c¹. It will be seen that the vertical movements of the horn are
imparted, through the spindle c', lever c³, connecting-rod 14 and the described
intermediate devices, to the disk, a downward movement of the horn causing a
movement of the anvil away from the cutters, while an upward movement of the
horn causes a movement of the anvil toward the cutters.
The anvil is given a longitudinal reciprocating movement, by means of a
lever 1 (Figures 3, 15 and 25,) pivoted at 16 to the supporting-frame and having
at one end a trundle-roll, engaged with a cam 17 on the driving-shaft, the lower
end of said lever being provided with an ear 18, which is pivotally connected at j¹º
with the rear end of the anvil j. The rotation of the cam causes the lever to
oscillate, and thus reciprocate the anvil. The movements of the lever j¹s are so
timed that the anvil is at the rear extreme of its reciprocating movement, as shown
in Figures 15 and 25, when the wire is being fed across the anvil and cut off to
form a staple blank, the anvil being moved forward or in the direction indicated by
the arrow in Figure 15 after the staple blank has been engaged with the anvil and
cut off, this movement causing the anvil to carry the blank to a point under the
throat c, so that, upon the descent of the throat, the latter will bend the blank.
into the form of a staple g' across the anvil, as shown in Figure 10. The lateral
adjustment of the anvil, caused by the rotation of the disk j17, takes place when the
anvil is at the end of its backward movement and the slide is at its maximum
distance from the shaft or centre ja on which the disk turns; consequently, when
the anvil is moved forward from the position shown in Figures 15 and 25 to carry
the blank into position for bending, the slide j moves into alignment with the shaft
or centre when the anvil reaches the forward extreme of its movement, so that
the position of the anvil when it presents the blank to the bending throat is always
the same, regardless of the adjustment of the disk 77, the anvil being given a lateral
movement while it is moving forward, when the slot j is diagonal relatively to the
direction of longitudinal movement of the anvil.
We have provided devices for feeding the wire across the anvil a distance
corresponding to the vertical position of the horn, so that the length of the wire
feed, as well as the lateral position of the anvil, is determined by the distance
between the work-supporting end of the horn and the lower end of the throat
through which the staples are driven. Said wire-feeding mechanism will next be
described.
represents a wire-feeding arm, which is affixed to a tubular rod or shaft k¹
(see Figure 17), journalled in an outer tubular shaft k² (Figure 17), the latter
being journalled in a fixed bearing in the supporting-frame, and being connected, as
hereinafter described, with the horn, and provided with a feed-regulating arm k³,
which is bent or curved, as shown in Figure 3, so that its outer end extends across
the path in which the feed arm k is adapted to swing. The feed arm k is normally
pressed outwardly against the regulating arm k³, by means of a spring **, shown in
dotted lines in Figure 3, said spring being arranged so that it presses upwardly on

page_text: the outer end of an arm k³, affixed to the tubular shaft k', the pressure of said spring
tending to rotate the shaft k¹ in the direction required to press the feed arm k
against the regulating arm ³, so that said regulating arm constitutes a stop which
limits the movement of the feed arm away from the cutters, and is automatically
adjusted by the hereinafter described connections between the shaft to which the
said regulating arm is attached and the horn of the machine. The feed arm & is
moved inwardly toward the cutters at intervals, by means of a cam 4° (Figures 2
and 3), affixed to the driving-shaft, and a trundle-roll mounted on an extension k³
of the feed arm k, said extension and the trundle-roll being so arranged that the
pressure of the spring k, which holds the feed arın against the regulating arm, also
holds the trundle-roll ' against the cam ko.
The above-mentioned connections between the feed-regulating arm ³ and the
horn of the machine comprise the tubular shaft to which said arm is affixed an
arm (Figures 3 and 17) affixed to said shaft, and a link 2 connecting the arm k
with an arm 3 affixed to the rock-shaft j, said rock-shaft being connected with
the horn, as already described, by means of the arm 13, rod j, lever c³ and horn
spindle c. Vertical movements or changes of position of the horn are therefore
imparted, through the spindle c', lever c³, rod j, rock-shaft, arm k¹³, connecting-
rod and tubular shaft k³, to the regulating arm k³, the downward movement of
the horn causing an outward movement of said regulating arm, and permitting an
increased movement of the feed arm away from the cutters, while an upward
movement of the horn causes a movement of the feed-regulating arm toward the
cutters.
The feed arm is provided with a wire-receiving slot (Figure 17), near its
outer end, said slot passing transversely through the arm, its bottom coustituting a
bearing surface against which the wire is intermittingly clamped by means of a
clamping plunger 1, which is longitudinally movable in the arm k, and is provided
with a reduced lower end or jaw 16, adapted to enter and slide in the slot ". The
plunger is provided near its upper end with an incline k against which bears a
corresponding incline 18 on a rod or plunger 19 which is longitudinally movable
in the tubular shaft kl. When the plunger 4 is moved in the direction indicated
by the arrow in Figure 17, its incline k, acting on the incline of the plunger k
forces said plunger downwardly and causes it to co-operate with the bottom of the
slot in grasping the wire, this motion taking place when the feed arm k is moving
toward the cutters and thus causing the feed arm to positively grasp and move the
wire. The described movement is effected by means of a lever (Figure 3),
pivoted at to the frame of the machine, and provided with a trundle-roll engaged
with a cam affixed to the driving-shaft, and a rod 2, pivoted to the lever 20 and
bearing at one end against the plunger. The rotation of the cam 2 oscillates
the lever, thus reciprocating the rod and causing said rod to alternately press
the plunger in the direction indicated by the arrow in Figure 17 and release
said plunger, so that the wire is alternately grasped and released, the wire being
released when the feed arm is moving away from the cutters.
The backward motion of the wire with the feeding arm, when the latter is moving
backwardly, is prevented by means of a clamping jaw (Figures 1, 2, 13 and 14),
which is a short rod or plunger, fitted to slide in a guide formed for its reception in
the supporting-frame a, and arranged to co-operate with a flat surface a on the
supporting-frame in clamping the wire g. The jaw is provided with an incline 4,
on which bears a corresponding incline 6, on a rod or plunger ", which is
connected with the above-described lever 20 which operates the jaw 6 in the
feeding arm k, the last-mentioned jaw being operated from the lever 20 through the
rod or plunger, as already described. The plungers 23 and are located at
opposite sides of the pivot or fulcrum of lever k, so that the jaws and k
are operated alternately, the jaw being moved from the position shown in
Figure 13 to that shown in Figure 14 by the co-operation of the inclines 2 and 4*
just before the feeding arm & moves backwardly, so that the wire is rigidly confined
on the frame of the machine during the backward movement of the feeding arm.

page_text: The plunger is moved back to the position shown in Figure 13, thus releasing
the jaw and permitting the latter to release the wire just before the feeding arm
begins to move toward the cutters. The rod or plunger 2 may be connected to the
lever 20 in any suitable way. We prefer, however to connect it by the means
shown in Figure 13, one end of the plunger 27 being inserted in an orifice in the
lever, and provided with an incline 28, which bears on the incline 2 forming
one side of a recess cut in a screw-threaded rod 30, which is movable in an orifice
extending across the lever 20. A nut ª¹, engaged with said threaded rod, enables
the latter to be adjusted endwise and thus impart a slight longitudinal adjustment
to the plunger 2.
The horn c is at all times pressed upwardly against the stop which rests upon it,
by means of a light spring m, attached at its lower end at m¹ to the base of the
standard a', and at its upper end to a portion of the jointed connecting-rod c°, said
spring constantly exerting a downward pull on the connecting-rod, and consequently
an upward pressure, through the lever and spindle c', on the horn, so that the
horn is never allowed to descend by gravitation, but always exerts an upward
pressure on the stock; hence the position of the horn is always governed by the
thickness of the sole or material interposed between it and the throat or support
against which the stock is held by the upward pressure of the horn. This constant
upward yielding pressure of the horn against the work is an important feature of
our invention, since it enables the horn to constitute a reliable device for adjusting
the descent of the awls and for determining the length of the staples, as already
described. The pressure imparted by the spring m is necessarily light, however, to
permit the feeding of the work by the work-feeding devices hereinafter described, its
pressure being only sufficient to keep the horn in continuous contact with the work,
and the work in continuous contact with the throat or device against which it is
pressed by the horn. It is desirable, however, to give the horn a stronger pressure
against the material, and the material a stronger pressure against the throat, prior to
the operation of penetrating the stock by the awls and driving and clinching the
staples, in order that the stock may be firmly compressed between the horn and the
throat through which the staples are driven, before the horn is locked to support
the thrust or pressure of the awls and the driver, suitable locking devices being
provided whereby the horn is intermittingly locked or made rigid, as presently
described. We have therefore provided an auxiliary spring o, one end of which
bears on a collar or enlargement o' on the connecting-rod, o, while its other end
bears upon a tension-adjusting device, which is automatically moved by the power
of the machine so as to throw the pressure of the spring o upon the horn, through
the intermediate connections, after the material has been fed. The said tension-
adjusting device is a collar or sleeve 02, which is movable vertically upon the
connecting-rod c, and is adapted to be depressed thereon to compress the spring o,
and raised to loosen said spring. The sleeve o² is attached at its upper end to an
arm (Figures 3 and 16) through which passes a vertical rod of, the upper end of
which is connected by a pivot of with a link o°, pivoted at o' (Figure 5) to an arm
or lever o8, which is pivotally connected at o with the supporting-frame of the
machine. o represents a cam, affixed to the driving-shaft b, and arranged to bear
upon the lever o and depress the latter once during each rotation of the driving-
shaft. The rod o is pressed upwardly by a spring o¹ toward the cam 01. Said
rod is provided with an incline o' (Fig. 16, which bears against the inclined end of
a locking collar o, which is fitted to move slightly in a slot in the arm o³, and a
direction at right angles with the connecting-rod c, said locking collar surrounding
the sleeve o². When the rod of is raised by the spring o¹, the incline o leaves the
locking collar o in a loose condition on the sleeve o. The contact of the cam o¹º
with the lever o depresses the rod 0, and thus causes the incline o¹³ on said rod to
press the locking collar o firmly against the sleeve o³, so that said locking collar
constitutes a rigid connection between the rod of and the sleeve o³, said rod and
sleeve being moved downwardly together by the action of the cam o on the
lever 08.
The spring o is thus compressed and exerts a downward pressure upon

page_text: the connecting-rode, which pressure is imparted in a reversed direction to the
horn. When the cam co, in its revolution, passes away from the lever o³, the
spring raises the rod ot, thus causing the incline o to release the locking
collar o¹, and remove the pressure of the spring o from the connecting-rod and
horn. A spring o", which is weaker than the spring o, is preferably interposed
between the under side of the arm oª and a nut or enlargement on the lower end of
the rod o, said weaker spring constituting a yielding stop or cushion for the rod o*
when the latter is raised.
The horn is locked, preparatory to the operation of perforating the material and
driving the staple, by means of a locking collar p (Figures 3 and 16), surrounding
the connecting-rod o, and connected by a rod pl with a suitable moving part of the
machine, preferably the lever k20, as shown in Figure 3, the arrangement being such
that, when the rod p¹ is moved in the direction indicated by the arrow marked
thereon in Figure 16, the long collar p will be caused to bind upon the rod co,
and thus rigidly lock said rc. to the supporting-frame, the locking collar being
interposed between two ears as a, affixed to the supporting-frame and preventing
vertical movement of the locking collar, the connecting-rod e being adapted to slide in
orifices in said ears. The movements of the locking collar p are so timed that the
horn is locked and made rigid after the compression of the spring o, and before the
descent of the awl and driver, and is released and left free to slide vertically in
the ears a after the sole has been penetrated and has received the staple, and after
the spring o has been released.
The feeding mechanism which we prefer to employ to feed the work after the
driving of each staple is as follows: represents a feed dog, attached to a lever r³,
which is pivoted at (Figure 2) to an arm 3, loosely mounted upon a stud 10, on
a crank or offset arm, affixed to a rock-shaft . Said rock-shaft is journalled in
fixed bearings on the supporting frame, and is rocked or oscillated by means of a
cam (Figure 5) on the driving shaft, an arm affixed to a tubular rock-shaft
journalled on a fixed bearing and provided with an arm, and an arm 10 connected
by a bolt with the arm. 13 represents another rock-shaft, journalled in fixed
bearings on the supporting-frame, parallel with the rock-shaft, and provided at
one end with a crank or offset arm 14 (Figures 2 and 4). 16 represents a rod,
pivoted at its lower end to an arm 17 (Figures 2 and 4), affixed rigidly to the
crank and at its other end to a lever, which is pivoted at 1 to the crank 14,
and has at one end a stud, which is engaged with the upper end of the feed dog
lever. The rock-shaft ¹³ is oscillated by means of a cam 1 (Figure 6), affixed
to the rock-shaft b, and an arm 1, affixed to said rock-shaft and having a trundle-
roll engaged with said cam. The arm or crank of the rock-shaft 19 extends in
a substantially horizontal direction, so that the stud 15 has an approximately
vertical movement; while the arm extends in a substantially vertical direction,
so that the stud 10 has an approximately horizontal movement; the result being
a four-part movement of the feed dog, the same moving downwardly horizontally in
one direction, then upwardly, then horizontally in the opposite direction. The
lever, to which the feed dog is attached, is located between two flanges do d
(Figures 2, 4 and 30) on the sliding head d, said flanges being in close contact with
the lever, so that the longitudinal movements of the head cause the lever to move
laterally, this movement being permitted by the loose connection of the lever with
the studs and . represents the reel upon which a coil of the wire g is
supported. Said reel is mounted to rotate loosely upon a stud s', which is affixed
to an arm or frame s³, which is pivoted at s to a fixed ear on the supporting-frame.
The frames has a downwardly projecting arm s (Figure 3), having a studs, on
which is mounted a trundle-roll, bearing upon a cam s affixed to the driving-
shaft. The trundle-roll is located at the opposite side of the pivot s from the
reel, and the arrangement is such that the weight of the reel will cause the trundle-
roll to bear yieldingly against the cam s'. The rotation of the cam gives the reel
an oscillating movement, for a purpose which will be presently described.

page_text: The operation is as follows:
The awls and driver being raised and the horn unlocked and supported only by
the pressure of the light spring m, the operator places the shoe upon the horn, the
sliding head d being in position to hold the awls in proper position over the work-
supporting anvil on the horn to penetrate the sole at the right place. The awls
then descend and perforate the sole, and at the same time the wire is fed across the
anvil by the feeding arm, and then cut, while the forward end of the wire is held
by the spring on the anvil. The anvil then moves forward, and at the same time
the awls rise out of the way of the anvil. The throat c¹ then descends and bends
the wire blank and holds it in line with the driver. The sliding head d then moves
forward carrying with it the throat, staple, driver, awls and feed dog, this motion
removing the throat from the anvil, and leaving it over the holes previously made
by the awls. The throat is then depressed, and bears on the upper surface of the
sole, and at this point the spring o is compressed, and its pressure is exerted on the
horn to compress the sole, after which the horn is locked, as above described.
The driver then descends and drives the staple the legs of the staple being at the
same time clinched upon the horn. The throat and driver then rise, and at the
same time the sliding head d moves about half-way back and then stops, leaving
the feed dog in line with the staple. While the head is in this position, the feed
dog is depressed, and enters the sole, after which the horn is unlocked and the feed
dog is moved horizontally to feed the work, the pressure of the spring o being at
this point removed, so that the horn is pressed only by the light spring m.
downward movement of the feed dog is produced by the downward movement of
the crank or arm of the rock-shaft, the rock-shaft being at this time held
stationary by its operating cam. When the feed dog has been depressed, the rock-
shaft is held stationary by its operating cam, and the rock-shaft is oscillated
to give the feed dog its forward horizontal movement. The upward and backward
movement of the feed dog are similarly produced. After the feed dog has been
raised from the work, the sliding head d completes its backward movement, thus
bringing the awls again into position to penetrate the work. The described means
for oscillating the reel are timed to give the reel a downward swinging movement
toward the cutters while the wire-feeding arm k is moving backward to take a
fresh hold upon the wire, said movement of the reel making the wire slack between
the reel and the cutters. The reel remains depressed until the wire has been fed
by the feeding arm k. The reel swings upwardly while the wire is locked to the
feed arm.
The object of the described swinging movement of the reel is to enable
the feed arm to quickly feed or move the wire forward without being obliged to
overcome the inertia of the reel by pulling the wire directly from the reel, the
slack in the wire between the reel and the feed arm, caused by the downward
movement of the reel, affording sufficient or nearly sufficient wire for the next
staple.
The
The manner in which the position of the anvil relatively to the cutters and the
length of movement of the wire-feeding arm are controlled by the position of the.
horn has been already fully described, and from the description it will be apparent
that the depth to which the awls penetrate the sole is also controlled by the
vertical position of the horn, by reason of the fact that the lever is pivoted at
to the upper end of the connecting-rod c, so that the forward end of said lever,
which is connected by the link 12 with the awl-bar, is raised and lowered by the
downward and upward movements of the offset connecting-rod, so that, when the
connecting-rod is raised by an increase of thickness of the sole, resulting in a corre-
sponding depression of the horn, the forward end of the lever e' is correspondingly
depressed, so that the operation of the arm c that oscillates said lever will give an
increased downward movement to the awls. When the thickness of the sole
increases, the horn correspondingly rises, and the connecting-rod c is depressed so
that the awls are correspondingly raised and therefore enter the stock less deeply.
We believe ourselves to be the first to provide a staple-making and driving

page_text: machine having the following features, namely: First a pair of awls, adapted to
simultaneously make holes for the two legs of a staple, and connected with a
vertically movable horn, in such manner that the depth of penetration of the awls
will be determined by the vertical position of the horn; secondly, a horn, which
is at all times pressed upwardly by light spring pressure, and is intermittingly
pressed upwardly by heavier spring pressure before it is locked; thirdly, a staple-
forming anvil, which is movable laterally with relation to the wire-forming cutters,
and is controlled as to its distance from the cutters by the position of the horn;
and, fourthly, a sliding head, provided with awls, a feed device and a driver, and
mechanism for moving said head to bring said awls, feeding device and driver
interchangeably into a given position. We do not therefore limit ourselves to the
details of construction here shown, embodying said features, and may vary the
construction in various particulars, without departing from the spirit of our inven-
tion. Neither do we limit ourselves to the details of mechanism of various other
parts of the machine, not enumerated in the above list of novel features.
Those portions of our invention which relate to the operation of inserting a
fastening device in the material are not necessarily limited to machines in which
the fastener is made as well as driven, nor to machines in which the fastening
device is a staple, as several of the important features of our invention may be used
in connection with machines for driving fasteners previously made by another
machine, and in machines for making and driving single nails not of staple form.
When the machine is not used for making and driving staples, the throat, which
guides the driver while engaged with the sliding head so as to be interchangeably
in position with the awl, need not necessarily be reciprocated vertically.
By the term sliding head, as used in this Specification, we mean any carrier
which is engaged with the awl-bar and the driver-guiding throat, and is adapted to
be moved back and forth in such manner as to cause the awl-bar and throat to
interchangeably occupy substantially the same position. The back and forth
motion may be imparted to the said head or carrier in any suitable way, our inven-
tion not being limited to a carrier which slides in a guide.
The terms horizontal and vertical, as applied to the direction of movement of
the head, awl-bar, throat and driver, are used relatively, and are intended to
express the idea that the movement of the head is substantially at right angles to
the movement of the awl-bar, throat and driver.
In case the machine, provided with a sliding head, an awl-bar and a throat
engaged with said head, and a driver guided by the throat, is used for driving
single nails or fastenings, only one awl will be required on the awl-bar: hence,
in several of the following claims, we have specified the awl-bar having a
perforating awl.
