and EDWARD BAYLISS SEAVER, of 118, South Street, both in Boston, Massa-
chusetts, U.S.A.].
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 to be as follows :-
This invention relates to that class of boot and shoe nailing machines in which the
nails are cut from a continuous wire and driven by the same machine, and in which
the work is supported by a vertically movable horn during the driving operation, and
the length of the nails is automatically regulated by the vertical position of the horn.
The invention has for its object to provide certain improvements, first, in the means
for feeding the work after each nail is driven, secondly in the means for automatically
varying the length of the nails by variations in the thickness of the sole, and thirdly
in the means for locating the nails in the throat through which they are driven into
the sole.
To these ends my invention consists in the improvements which I will now proceed
to describe.
In carrying my said invention into practice I provide a supporting post or pedestal
to which is affixed the head or frame supporting the driving shaft. Said shaft has a
series of cams which actuate the operative parts of the machine as hereinafter described.
The awl bar and the driver bar of the machine are provided respectively with an
awl and driver. Said bars are fitted to reciprocate vertically in fixed guides in the
frame, the awl having no lateral movement, for the purpose of feeding the work, as in
other machines of this class.

page_text: The bar is reciprocated by a disc having a cam groove, said cam being mounted on the
driving shaft, a rock shaft journalled in a bearing affixed to the head or frame, and two
arms affixed to said rock shaft, one of which arms is engaged by a roller with the said
cam groove and the other arm with the awl bar by means of a slot receiving
a block
pivotted to said bar. The driver bar is depressed to drive the nails by a spring of any
suitable construction. The spring may be composed of two flexible wooden bars
connected at their rear ends by a headed bolt, and an adjustable nut thereon, and
slightly separated near said bolt by a transverse pin. The forward ends of said bars bear
respectively against a stirrup affixed to an arın on the frame and against a cap attached
to the upper end of the driver bar.
The driver bar is raised against the pressure of its spring by a semi circular cam
affixed to the side of the disc on the driving shaft, said cain being formed to alternately
bear against and raise a block affixed to the driver bar, and release said block, thus
alternately raising and releasing the driver bar, which is forcibly depressed by its
spring when released.
During the nailing operation the sole is pressed against a throat through which the
nails are forced by the driver into the sole.
The work is fed by an independent four motioned feeding dog, which is attached to
one arm of a two armed lever. Said lever is affixed to a rock shaft, which is adapted
both to oscillate and to move longitudinally in bearings affixed to the frame, the feed
dog being moved laterally by the longitudinal movements of the lever, and vertically
by the oscillating movements. The said movements alternate so that the dog is first
depressed and caused to engage the sole by the downward oscillating movement of the
lever, then caused to feed the work by a lateral movement of said lever, then raised by
the upward oscillating movement of the lever, and then moved laterally back to its
original position while raised out of contact with the sole.
The described lateral movement of the lever and the feed dog, are effected by means
of a cam on the driving shaft, a lever affixed to a socket which is mounted on a stud
or bearing affixed to the frame, said lever bearing at one end against the cam and at
the other end against the rock shaft and a spring inserted in a cavity formed in the
rock shaft and serving to press the rock shaft against the lever and thus keep the
upper end of said lever in contact with the cam.
The oscillating movements of the lever are effected by a second lever pivotted to
the frame and slotted at its lower end to receive a block pivotted to the first lever a
cam against which the upper end of the second lever bears, and a spring which is held
in a socket in the frame and bears against the second lever so as to press its upper end
against the cam.
The work supporting horn is attached to a vertically movable standard which is
supported by a lever pivotted to the base of the standard of the frame the movable
standard being connected to one end of said lever so that it is capable of being moved
vertically by the oscillations of said lever as usual in machines of this class.
The opposite end of the lever is connected by a vertical rod with one end of a bell
crank lever pivotted to the frame. The other arm of said lever has a roller which
bears on a cam on the driving shaft. This cam is formed to give the lever the
oscillating movements required to cause it to depress the horn at intervals by raising
the rod, and thus cause the horn to release the work held between it and the throat
during the feeding of the work, the horn being normally raised or pressed upwardly
by a spring interposed between a collar attached to the movable standard and one of the
guides in which said standard slides.
A positively rotated feed roll co-operates with a spring pressed roll in feeding the
wire from which the nails are made, intermittingly to the severing and point forming
cutters hereinafter described. The positively rotated roll is mounted on an arbor
journalled in bearings on the frame said arbor being rotated intermittingly by means
hereinafter described. The spring pressed roll is journalled in a sliding holder said
holder and its roll being pressed toward the roll by a spring in a fixed socket in which
the holder is adapted to slide.
To the arbor carrying the feed roll is rigidly attached a ratchet with which engages

page_text: a pawl pivotted to an ear on a sleeve or collar fitted to turn loosely on one of the
bearings in which the arbor is journalled.
On the sleeve is formed a rack segment meshing with a rack segment on a lever
pivotted to an ear on the frame and having a stud or roll entering a cam groove in a
disc on the driving shaft. The rotation of the disc causes the groove to oscillate the
lever and rack segment and thus oscillate the sleeve, and cause its pawl to alternately
engage with the stop on the ratchet so that the arbor and feed roll are thus rotated
intermittingly, the arbor remaining at rest when the pawl is slipping back on the feeth
of the ratchet.
In machines of this class it is usual to provide means whereby the length of the
feeding movement of the wire and therefore the length of the nails is governed by the
distance between the end of the horn and the throat through which the nails are driven,
so that the length of the nails is caused to conform automatically to the thickness of
the part of the sole, that is interposed between the horn and throat.
I have provided improved automatic means whereby the length of the nails formed
is caused to exceed the distance between the end of the horn and the throat, and
whereby any increase in said distance causes a greater increase in the length of the
nail, so that the length of the nail in all cases has a given relation to the thickness of
the sole. In other words when the horn is separated from the throat a quarter of an
inch by the interposed work, the nail formed will have a greater length, say three
eighths of an inch, and when the separation of the horn from the throat is increased
to half an inch by an increase in the thickness of the interposed work, the length of
the nail instead of being increased to exactly correspond to the increase in the
thickness of the work so as to still exceed the thickness of the work by one eighth of an
inch, will be proportionately increased to six eighths of an inch, the excess in the
length of the nail over the thickness of the work being doubled. The object of this
proportional variation in the surplus length of the nail is to compensate for the
longitudinal compression or shortening of the nails by the driver during the driving
operation, the nails being cut from wire made by forming a thin strip of sheet metal
into a tube around a fibrous cord or core. This construction of the wire makes the
nails liable to be compressed longitudinally or shortened by the driver, and the extent
of such compressing or shortening is in proportion to the length of the nail, a nail
half an inch long being shortened twice as much as one a quarter of an inch long.
The means which I employ to produce the described proportional variation in the
surplus length of the nails are as follows-
Journalled in a bearing on the frame is a rock shaft to one end of which is affixed a
pinion and to the other end an arm having a segmental plate or shield concentric with
another rock shaft said shield projecting over a portion of the perimeter of a new
ratchet and being formed to be interposed between the ratchet and its pawl, to any
desired extent so as to prevent the pawl from engaging with the ratchet during a
portion of its forward movement and thus limiting the extent of movement imparted
to the ratchet and feed roll by the forward movement of the pawl.
A rack is fitted to slide in a vertical guide in the frame and meshes with the pinion
on a rock shaft. Said rack is connected by a downwardly extending rod with an arm
on the rod which connects the horn supporting lever with the bell crank lever bearing
on the cam, so that any vertical movement of said road is imparted to the rack, and the
latter is caused thereby to partially rotate the pinion and rock shaft and segmental
shield, in one direction or the other, according to the direction of movement of
the rod.
The arrangement of the shield is such that when the horn is raised to its highest
point the shield projects under the pawl, to such an extent as to permit the pawl to
engage with the ratchet during a limited portion of its forward movement, the pawl
bearing on the outer surface of the shield, during the last part of its forward move-
ment, and passing off from the shield and engaging with the ratchet during the latter
part. The feed roll therefore, has the shortest movement when the horn is in its
highest position.
When the horn is depressed the shield is moved back so that it intercepts the pawl

page_text: less, and permits it to give the ratchet and feed roll a longer movement, the length of
movement depending on the extent of the depression of the horn.
The described devices are proportioned and arranged to give the nails the above
described proportional surplus, the increase in the length of the feed movement, caused
by a depression of the horn a given distance, being more than twice the increase
caused by a depression of the horn half of said distance.
The wire is drawn from a coil supported by a reel, journalled on a stud, affixed to
the frame, and passes from the reel between the feed rolls and bears against a grooved
finger, affixed to a lever, which is pivoted to the frame, and has secured to its lower
end at a point below the finger a V-shaped cutter.
A second cutter is adjustably secured to a holder, affixed to the frame and provided
with a V-shaped groove formed to receive the V-shaped cutter. The intersection of
the end of the cutter and the sides of the V-shaped groove therein form cutting edges,
which cooperate with the cutting edges formed by the intersection of the sides and end of
the V-shaped-cutter in severing the wire with a V-shaped cut, thus forming at one
operation a V-shaped notch in the outer end of the nail detached by the operation of
the cutters, and a V-shaped end on the wire which end forms the point of the next
nail. Within the groove in the second cutter is an adjustable piece, having a bevelled
end, which cooperates with the end of the V-shaped cutter in compressing the points
formed on the wire by the cutters.
A lever is connected by a rod to an oscillating lever, which is pivoted to the frame,
and has a roller projecting into a cam groove, in a disc on the driving shaft. The
oscillating lever is oscillated by the rotation of the disc, and oscillates the first lever.
When the cutter carrying end of the latter lever advances toward the cutter the finger
bearing against the wire moves its lower end laterally into position to enter the orifice
in the throat before the wire is fed, the feeding movement and the severing of the wire
taking place immediately after the lateral movement thereof.
The nail is thus placed in position to be driven before it is severed from the wire,
and the use of a carrier to move the nail into position to be driven after it is severed
from the wire is avoided.
The described mechanism is timed to operate as follows:-
The work being held between the horn and throat, the awl descends and perforates
the sole and then rises. While the awl is rising the feed dog descends and engages
the sole. The horn is then depressed, releasing the work and the feed dog is moved
laterally the required distance to feed the work. The horn then rises and clamps the
work against the throat, and after the work is clamped the feed dog rises. During the
feeding movement of the work the wired is moved laterally into line with the orifice in
the throat, and after the work is clamped the wire is fed into the throat and then cut,
a nail being thus left in the throat. The cutter and bending fingers then move back
and the driver descends and forces the nail into the sole. After the nail is driven and
while the work is clamped between the horn and throat, the awl descends and forms
the next hole, and thus the operation is continued.

Improvements in Nailing Machines for Use in the Manufacture
of Boots and Shoes.
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 :-

page_text: The same letters of reference indicate the same parts in all the figures.
a represents the supporting post or pedestal to which is affixed the head or frame a¹
supporting the driving shaft b. Said shaft has a series of cams which actuate the
operative parts of the machine as hereinafter described.
c represents the awl bar, and d the driver bar, provided respectively with the awl e
and driver f. Said bars are fitted to reciprocate vertically in fixed guides g g, in the
frame a¹ the awl having no lateral movement, for the purpose of feeding the work, as
in other machines of this class.
The awl bar is reciprocated by a cam groove h (Figures 5 and 6) in a disc i on the
driving shaft, a rock shaft journalled in a bearing affixed to the head or frame, and
two arms k,l affixed to said rock shaft, the arm k being engaged by a roller with the
cam groove h, and the arm / with the awl bar by means of a slot m receiving a block n
pivoted to said bar. The driver bar is depressed to drive the nails by a spring of any
suitable construction. The spring shewn is composed of two flexible wooden bars o, o,
connected at their rear ends by a headed bolt p and an adjustable nut thereon, and
slightly separated near said bolt by a transverse pin q. The forward ends of said bars
bear respectively against a stirrup affixed to an arm on the frame a¹ and against a
caps (as shewn in Figures 1 and 3) attached to the upper end of the driver bar.
The driver bar is raised against the pressure of the spring by a semicircular can t
(Figures 5, 7 and 8) affixed to the side of the disc u on the driving shaft, said cam
being formed to alternately bear against and raise a block affixed to the driver bar,
and release said block, thus alternately raising and releasing the driver bar, which is
forcibly depressed by its spring when released.
o represents the throat against which the sole is pressed during the nailing operation
and through which the nails are forced by the driver into the sole.
The work (instead of being fed by a lateral movement of the awl as usual in machines
of this class, is fed by an independent feeding dog e¹ which is attached to one arm of
a two armed lever 6. Said lever is affixed to a rock shaft d¹, which is adapted both to
oscillate and to move longitudinally in bearings e¹ e' affixed to the frame a¹, the feed
dog being moved laterally by the longitudinal movements of the lever, and vertically
by the oscillating movements. The said movements alternate so that the dog is first
depressed and caused to engage the sole by the downward oscillating movement of the
lever b¹ then caused to feed the work by a lateral movement of said lever, then raised
by the upward oscillating movement of the lever, and then moved laterally back to its
original position while raised out of contact with the sole.
The described lateral movement of the lever and the feed dog, are effected by
means of a cam fl on the driving shaft, a lever g¹ affixed to a socket h¹ which is
mounted on a stud or bearing affixed to the frame a², said lever bearing at one end
against the cam and at the other end against the rock shaft d'; and a spring i¹
Figure 12 inserted in a cavity formed in the rock shaft and serving to press the rock
shaft against the lever g¹ and thus keep the upper end of said lever in contact with the
cam f¹
The oscillating movements of the lever b¹ are effected by a lever ¹ pivotted at /¹ to
the frame a¹ and slotted at its lower end to receive a block pivotted to the lever bl; a
cam m against which the upper end of the lever j¹ bears; and a spring n¹ (Figure 11)
which is held in a socket in the frame a¹ and bears against the lever j¹ so as to press its
upper end against the cam m¹.
o represents the work supporting horn attached to a vertically movable standard of
which is supported by a lever p¹ pivotted to the base of the standard a the standard o
being connected to one end of said lever so that it is capable of being moved vertically
by the oscillations of said lever as usual in machines of this class.
The opposite end of the lever p¹ is connected by a vertical rod q¹ with one end of a
bell crank lever, pivotted at st, to the frame a¹. The other arm of said lever has a
roller t¹, which bears on a cam u² on the driving shaft. The cam is formed to give the
lever the oscillating movements required to cause it to depress the horn at intervals by
raising the rod o* and thus cause the horn to release the work held between it and the
throat during the feeding of the work, the horn being normally raised or pressed

page_text: upwardly by a spring vl, interposed between a collar attached to the standard o' and
one of the guides in which said standard slides (see Figure 2).
aª represents a positively rotated feed roll which cooperates with a spring pressed
roll 6 in feeding the wire c², from which the nails are made, intermittingly to the
severing and point forming cutters hereinafter described. The positively-rotated roll
is mounted on an arbor d journalled in bearings on the frame a¹, said arbor being
rotated intermittingly by means hereinafter described. The spring pressed roll is
journalled in a sliding holder e², (shown in section in Figure 17) said holder and its roll
being pressed toward the roll a by a spring f' in a fixed socket in which the holder
is adapted to slide.
To the arbor carrying the feed roll a² is rigidly attached a ratchet g³ (Figures 4,
15 and 16) with which engages a pawl 2 pivoted to an ear on a sleeve or collar
which is fitted to turn loosely on one of the bearings in which the arbor is journalled.
On the sleeve is formed a rack segment 2 (Figure 17) meshing with a rack
segment k³ on a lever 12, which is pivoted at m² to an ear on the frame a¹ and has a stud
or roll o entering a cam groove n³ in a disc p² on the driving shaft. The rotation of
the disc p² causes the groove n² to oscillate the lever and rack segment k³, and thus
oscillate the sleeve, and cause its pawl h² to alternately engage with and stop on the
ratchet, so that the arbor d and feed roll a² are thus rotated intermittingly, the arbor
remaining at rest when the pawl is slipping back on the teeth of the racket.
In machines of this class it is usual to provide means whereby the length of the
feeding movement of the wire and therefore the length of the nails is governed by the
distance between the end of the horn and the throat through which the nails are driven,
so that the length of the nails is caused to conform automatically to the thickness of the
part of the sole that is interposed between the horn and throat.
I have provided improved automatic means whereby the length of the nails formed
is caused to exceed the distance between the end of the horn and the throat, and
whereby any increase in said distance causes a greater increase in the length of the
nail, so that the length of the nail in all cases has a given relation to the thickness of
the sole. In other words when the horn is separated from the throat a quarter of an
inch by the interposed work, the nail formed will have a greater length, say three
eighths of an inch, and when the separation of the horn from the throat is increased to
half an inch by an increase in the thickness of the interposed work, the length of the
nail instead of being increased to exactly correspond to the increase in the thickness
of the work so as to still exceed the thickness of the work by one eighth of an inch,
will be proportionately increased to six eighths of an inch, the excess in the length of
the nail over the thickness of the work being doubled. The object of this proportional
variation in the surplus length of the nail is to compensate for the longitudinal
compression or shortening of the nails by the driver during the driving operation, the
nails being cut from wire made by forming a thin strip of sheet metal into a tube 2,
around a fibrous cord or core 3 (see Figure 23). This construction of the wire makes
the nails liable to be compressed longitudinally or shortened by the driver, and the
extent of such compression or shortening is in proportion to the length of the nail,
a nail a half an inch long being shortened twice as much as one a quarter of an
inch long.
The means which I employ to produce the described proportional variation in the
surplus length of the nails are as follows:
Journalled in a bearing on the frame a¹ is a rock shaft to one end of which is
affixed a pinion t2, and to the other end an arm 2 having a segmental plate or shield ³,
concentric with the rock shafts said shield projecting over a portion of the perimeter
of the ratchet g³, as shown in Figures 15 and 16, and being formed to be interposed
between the ratchet and its pawl to any desired extent, so as to prevent the pawl
from engaging with the ratchet during a portion of its forward movement, and thus
limit the extent of movement imparted to the ratchet and feed roll by the forward
inovement of the pawl.
a represents a rack which is fitted to slide in a vertical guide in the frame a¹ and

page_text: meshes with the pinion on the rock shafts. Said rack is connected by a downwardly
extending rod 63, with an arm c³ on the rod q', which connects the horn supporting
lever with the bell crank lever bearing on the cam u¹, so that any vertical
movement of said rod is imparted to the rack, and the latter is caused thereby to
partially rotate the pinion 2 and the shaft and segmental shield v³, in one direction
or the other, according to the direction of movement of the rod q'.
The arrangement of the shield 2 is such that when the horn is raised to its highest
point the shield projects under the pawl g² to such an extont as to permit the pawl to
engage with the ratchet during a limited portion of its forward movement, the pawl
bearing on the outer surface of the shield, as shown in Figure 16, during the first part
of its forward movement, and passing off from the shield and engaging with the ratchet
during the latter part. The feed roll a' therefore, has the shortest movement when the
horn is in its highest position.
When the horn is depressed the shield is moved back, so that it intercepts the pawl
less, and permits it to give the ratchet and feed roll a longer movement, the length of
movement depending on the extent of the depression of the horn.
The described devices are proportioned and arranged to give the nails the above.
described proportional surplus, the increase in the length of the feed movement, caused
by a depression of the horn a given distance, being more than twice the increase
caused by a depression of the horn half of said distance.
The wire is drawn from a coil supported by a reel d³ journalled on a stud e³
affixed to the frame a¹, and passes from the reel between the feed rolls and bears
against a grooved finger, affixed to a lever g which is pivotted at h³ to the frame a!,
and has secured to its lower end at a point below the finger fa V-shaped cutter 1³.
represents a cutter adjustably secured to a holder ³, affixed to the frame a¹ and
provided with a V-shaped groove formed to receive the V-shaped cutter. The
intersection of the end of the cutter and the sides of the V-shaped groove therein
form cutting edges, which cooperate with the cutting edges formed by the intersection
of the sides and end of the cutter in severing the wire with a V-shaped cut, thus
forming at one operation a V-shaped notch in the outer end of the nail detached by
the operation of the cutters, and a V-shaped end on the wire which end forms the point
of the next nail (see Figure 23). Within the groove in the cutter is an adjustable
piece m³, having a bevelled end, which cooperates with the end of the cutter
compressing the points formed on the wire by the cutters.
in
The lever g is connected by a rod o³, to a lever p³, which is pivotted at q³ to the
frame a', and has a roller projecting into a cam groove in the disc i on the driving
shaft. The lever p* is oscillated by the rotation of the disc i, and oscillates the lever g
When the cutter carrying end of the lever g advances towards the cutter the
finger bearing against the wire moves its lower end laterally into position to enter the
orifice in the throat before the wire is fed, the feeding movement and the severing of
the wire taking place immediately after the lateral movement thereof.
The nail is thus placed in position to be driven before it is severed from the wire,
and the use of a carrier to move the nail into position to be driven after it is severed
from the wire is avoided.
The described mechanism is timed to operate as follows:-
The work being held between the horn and throat, the awl descends and perforates
the sole and then rises. While the awl is rising the feed dog descends and engages
the sole. The horn is then depressed, releasing the work and the feed dog is moved
laterally the required distance to feed the work. The horn then rises and clamps the
work against the throat w, and after the work is clamped the feed dog rises. During
the feeding movement of the work the wire is moved laterally into line with the orifice
in the throat, and after the work is clamped the wire is fed into the throat and then
cut, a nail being thus left in the throat. The cutter and bending fingers then
move back and the driver descends and forces the nail into the sole. After the nail is
driven and while the work is champed between the horn and throat, the awl descends
and forms the next hole, and thus the operation is continued.
