Improvements in and relating to Apparatus employed in Inserting
Nails or Fastenings in the Manufacture of Boots, Shoes, and the
like.
A communication from abroad by JAMES WILLSON BROOKS, of Petersham, County of
Worcester, State of Massachusetts, United States of America, Gentleman.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention to
be as follows:-
This invention relates to apparatus employed in the manufacture of boots and
shoes, wherein nails or fastenings are cut from suitable wire like material to be
driven by suitable devices into the outer sole to confine it to the upper and inner
sole, or to re-inforce or quilt said inner sole, and also to slug the heel of a shoe; the
apparatus herein described having means for adapting the fastenings to the thick-
ness of the stock when uniting an outer sole to an inner sole, and it is also adapted
to be used for slugging a heel or quilting a sole, the length of the fastening in such
use being uniform, and wire like material of any desired shape in cross section may
be driven by the apparatus.
The work support or horn and the co-operating presser are automatically separated,
by means suitable therefor, when the nailing operation ceases, to thereby permit the
work to be freely moved between the work support and presser, or to be removed
from or applied to the apparatus, and the construction in general is simplified in
various particulars.
The wire like material from which the nails or fastenings are cut is contained in a
horizontally supported reel or carrier freely rotatable about a central support and
open interiorly to permit the wire-like material to be drawn from the inside of the
coil as it is fed to the inserting and severing devices, the rotation of the coil and
reel preventing twist in the wire between the reel and the cutting and driving
devices.
Means are also provided whereby, when the clutch and driver pulley are released
the last nail, before stopping, will be driven and the horn or work-support depressed
by the momentum of the main driving shaft so that when the brake is applied to
bring the apparatus to a full stop there is very little resistance to overcome, and the
main shaft and cooperating mechanism will be stopped immediately without undue
shock.
The main frame work comprises a column or standard having at its upper end a
head to support the various working parts, while a horn of usual shape is rotatable on
a longitudinally movable shaft supported near the lower end of the column.
The horn is supported in a yielding manner by means of a spring in a manner
somewhat similar to that shown in the Specification of Patent No. 1492 dated
January 24th 1893, granted to Alfred George Brookes, the horn being depressed
while the stock is being fed, and a device is provided to permit the rising of the horn

page_text: against the underside of the stock, whatever its thickness, prior to the insertion of a
nail or fastening therein.
The head supports a main shaft having a cam disc thereon, the periphery of which
forms one member of a friction clutch, the other member of the clutch being loosely
mounted on the main shaft and adapted to be continuously driven, the clutch being
thrown into or out of operation either automatically or at the will of the operator, the
latter movement being effected by means of a suitable foot, treadle and link.
The cam disc has on its inner face a cam, which, through intervening devices, is
connected with and automatically governs the operation of the clutch. A brake shoe
embraces the rim of the cam disc fast on the main shaft, and the clutch controlling
cam operates to press the shoe against the disc and completely brake and stop its
rotation when the clutch is fully released, the movement of the clutch into operative
position being accompanied by release of the brake shoe.
A cam groove is formed in the inner face of the disc fast on the main shaft, to
engage a suitable stud on a pivoted lever, the other end of the latter being connected
with the horn carrying shaft, so that when from the shape of the cam groove the
outer end of the lever is elevated the horn will be depressed to unclamp the stock,
the latter at such time being fed over the horn.
The cam groove has a certain enlargement to permit free play of the stud on the
lever, and unless prevented, by means to be described, the latter will bear against
the outer circular wall of the groove to act through intervening devices to permit the
spring to raise the horn and to clamp the stock.
In the operation of the apparatus the horn will be automatically raised and
lowered at each revolution of the disc on the main shaft provided the operator
maintains the clutch and brake controlling devices inoperative, and at each revolution
of the disc a nail or fastening may be driven, the operation continuing until the
nailing has been effected.
If, however, the operator permits the clutch and brake controlling devices to
operate after starting the apparatus, such devices will operate to automatically stop
the movement of the parts after the main shaft and disc have made a single rotation,
one fastening having been driven, and with such operation of the apparatus an
auxiliary device is provided to give a final movement to the cam actuating lever
which controls the horn, to so swing the lever that the horn will be positively
depressed as the apparatus comes to a full stop.
The apparatus, therefore, is always in readiness to receive the stock or to permit
its ready removal before or after nailing respectively, so that the depression or
lowering of the horn by the act of the operator is obviated.
It is to be understood that even when the apparatus has been running to turn the
main shaft through two or a number of revolutions, the auxiliary device will be put
into operation automatically whenever the apparatus is about to be stopped so that
the horn will be positively depressed.
To determine the length of the nail or fastening to be cut from the wire-like
material, a longitudinally movable measuring leg is provided, the extent of its
longitudinal movement determining the length of the nail or fastening, the leg
being connected with the feeding mechanism which engages and feeds the wire-like
material used, and when the latter is fed forward more or less by such mechanism
cutters are actuated to cut or sever a portion of the wire to form the nail or fastening
to be driven.
The fastening cut from the wire-like material enters a guide passage and is driven
into the stock by a suitably actuated reciprocating driver, the fastening being inserted
by the driver in a hole previously made in the stock by an awl, which latter may also
be utilized to feed the stock over the horn.
On the head of the apparatus an upturned arm is cupped out to form an annular
raceway for a series of anti friction rolls upon which rests the lower end of the reel
hub, which latter is held in place by a pin extended loosely in the hub and into a
hole in the end of an upturned arm. The reel consists essentially of an annular
bottom plate and a series of arms radiating from the hub and downturned at their

page_text: ends to meet the plate, such reel being conveniently inade as a single
casting.
One of the arms is not connected to the bottom plate, to thereby leave an opening
through which the coil of wire-like material is inserted to rest upon the bottom
plate.
The wire is drawn from the interior of the coil through the open centre of the
bottom plate of the reel, and thereby causes the reel to rotate freely in a horizontal
plane about its vertical axis, and as the wire passes to the fixed guideway the rotation
of the reel about a fixed vertical pivot prevents twisting of the wire.
The arrangement and operation of the clutch, brake and driving mechanisms, is
such that the clutch is first released, and then later on the brake is applied, the
momentum of the main driving shaft after unclutching being taken up and utilized
by the driving mechanism and by the horn depressing devices so that when the brake
is applied there is very little resistance to overcome and the apparatus will be stopped
immediately without undue shock.
The horn is periodically depressed when the apparatus is in operation, to unclamp
the work in order that it may be fed, and the horn is also finally depressed at the
stoppage of the machine whether a single nail or fastening or any number be driven,
and the periodical and final depression of the horn are governed by independently
operative controlling devices.
Both the periodical and final depression of the horn are automatic, and the apparatus
when stopped is always in a position to have the work removed, and consequently
the apparatus is always ready to receive work without necessitating the lowering or
depression of the horn by the operator.
Improvements in and relating to Apparatus employed in Inserting
Nails or Fastenings in the Manufacture of Boots, Shoes, and the
like.
A communication from abroad by JAMES WILLSON BROOKS of Petersham, County of
Worcester, State of Massachusetts, United States of America, Gentleman.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, 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 that class of nailing machines employed in the manufacture
of boots and shoes, wherein nails or fastenings are cut from suitable wire like material
to be driven by the machine into the outer sole to confine it to the upper and inner
sole, or to re-enforce or quilt said outer sole and aiso to slug the heel of a shoe.
The machine herein to be described has means for alapting the fastenings to the
thickness of the stock when uniting an outer sole to an inner sole, and it is adapted to be
used for slugging a heel or quilting a sole, the length of the fastening at such time
being uniform, the machine being readily adapted for driving wire like material of
any desired shape in cross section.
In the machine to be described, I have provided means whereby the work-support

page_text: or horn and the co-operating presser are automatically separated when the nailing
operation ceases to thereby permit the work to be freely moved between said work-
support and presser or to be removed from or applied to the machine, and I have
simplified the construction of the whole apparatus in various particulars, as will be
hereinafter fully described.
The wire-like material from which the nails or fastenings are cut is contained in a
horizontally supported reel or carrier, freely rotatable about a central support, and
open interiorly to permit the wire-like material to be drawn from the inside of the
coil as it is fed to the apparatus, the rotation of the coil and reel preventing twist in
the wire between the reel and the cutting and driving mechanisms.
I have also provided means whereby when the clutch and driver pulley are released
the last nail, before stopping, will be driven and the horn or work-support depressed
by the momentum of the main driving shaft, so that when the brake is applied
to bring the mechanism to a full stop there is very little resistance to overcome
and the main shaft and co-operating mechanism will be stopped immediately.
Figure 1 is a right hand side elevation of the upper part or head of a nailing
machine embodying my invention, the column, provided with a base to rest on the
floor, being omitted, as are the usual treadles connected therewith.

column and base, with the treadles for controlling the machine and moving the
horn or work-support.

gauge to be described.
Figure 13 is an enlarged sectional view of the reel or carrier for the wire-like nail
material, on the line Y-Y, Figure 14 and
Figure 14 is an enlarged top or plan view of the reel or carrier.
The main-frame work comprises a column A having at its upper end a head A¹ of
suitable shape to provide bearings or supports for the various working parts, the
base A2 of the column, see Figure 2, resting on the floor, and supporting the treadles,
to be described, the horn B, of usual shape, being rotatable on the horn shaft B,
longitudinally movable in a suitable bearing A³ of the column.
The horn shaft is prolonged by a rod B2, jointed to a treadle B³, surrounded by a
spiral spring B4, within the base, the spring at its upper end bearing against the
adjustable nut B6 screwed on the rod B2, to support the horn in a yielding manner,
as shown in Figure 2.
The treadle B³ has jointed thereto at its rear end a rod BB the upper end of which
is formed as a rack ³, longitudinally movable in guides d³ on the column, said rack
being engaged by a pawl d on a pawl carrier d² which is lifted once at each revolution
of the main shaft, to be described, to thereby, through the rod B8 and treadle B
depress the horn B while the stock is being fed, the pawl carrier 12 being also guided
by the guides d³, as shown.

page_text: The cam block & disengages the pawl d from the teeth of a rack d³ as the carrier is
depressed, the spring B4, see Figure 2, then immediately acting to raise the horn B
against the underside of the stock, whatever its thickness.
By means of the foot treadle B10 the operator may depress the horn, the rear end
of said treadle resting against the lever B³ at the rear of its fulcrum.
Referring to Figure 1, the main shaft C, shown by dotted lines, is supported in
bearings in the head A¹, and has fast thereon a cam disc C¹, the periphery of which
forms one member of a friction clutch, the movable member C² of said clutch being
shown as loose on the main shaft and adapted to be continually driven by a suitable
belt, not shown.
A collar C3 having a rearwardly inclined face C+ is longitudinally movable on the
main shaft between the hub of the member C2 and a collar C5 fast on the shaft, a
wedge block C attached to the upper end of a rod C7 throwing the clutch into or out
of operation, said rod being jointed at its lower end to a treadle C8 pivoted to the
base at C, see Figure 2, the rod being normally depressed by a suitable spring C,
Figure 1.
The disc C¹ has on its inner face a cam c, see Figure 5, against which is held a
roller or other stud c¹ on a lever c2 pivoted on a stud secured to the head, the
lever c² having mounted therein a short shaft c, Figures 1, 5 and 6, having an
eccentric or crank pin c thereon, fitted into a block c', which may be moved longi-
tudinally when the shaft c is turned by means of a handle c*.
At the outer side of the lever c² a sleeve is mounted to rock on the laterally
extended bub c³ of said lever, embracing the stud c4, said sleeve having two arms c
and c, see Figure 6, the former of which is grooved or recessed to embrace the
block c', while the arm c¹0 at its outer end, enters a recess c¹¹ in the clutch controlling
rod C7, as shown in Fig. 6.
After the horn has been finally depressed, the operator may turn the handle c* in
the direction of arrow 10 and the crank pin c will be turned to lower the block c
and move it to the left, Figure 6, rocking the sleeve c³ to depress the arm c¹0, depress-
ing the rod C, so that if thereafter for any reason the treadle is depressed, the said
rod cannot be lifted enough to throw the clutch into operation.
By this throw-off device I am enabled to render the machine inoperative, so that
various parts thereof may be adjusted and also preventing the machine from being
started accidentally.
A springs in a housing c¹ on the lever c² bears against a flattened portion of the
shaft c, to hold it in one or the other position.
The thin rim of the disc C¹ is embraced by a segmental brake shoe c¹³, which is
notched at c, Figure 6, to rest upon a lug e¹ on a collar c¹, clamped to the hub c³,
see dotted lines Figure 1, or forming part of the lever c², said hub extending between
the stud c and the outer sleeve c8.
The spring (normally holds the roll c¹ against the cam c, and when in the position
shown in Figures 5 and 6, the lug c¹5 presses the shoe against the disc C¹ to com-
pletely brake it when the clutch is fully released.
A cam groove e is formed in the inner face of the disc C¹, see Figure 5, to engage
and move a roller or other stud e¹ on a lever e², pivoted on a stud e³ in the heal, the
cam groove e being circular from the point 2 to point 3, so that no movement will be
transinitted to the lever e' between such points, the groove approaching and receding
from the centre from 3 to 4, to elevate the outer end of the lever, to which is pivoted
the upper end of a link e. connected to the pawl carrier d².
When the lever is thus lifted the horn B will be depressed, to unclamp the stock,
which at such time will be fed over the horn by means of the awl, the disc C¹ rotating
in the direction of the arrow 15, Figure 5.
Between the points 4 and 2 the groove is enlarged at ex, to permit free play of the
roll e¹, and unless prevented by means to be described the latter will bear against the
outer circular wall of the groove e, permitting the pawl carrier d² to be lowered
sufficiently to cause the release of the pawl d by the cam block 7, so that the
spring B will raise the horn and clamp the stock.

page_text: The inner end of the lever e² is notched or shouldered at es, Figure 5, to be at times
engaged by a pawl f, pivotally mounted in a boss f¹ of a pawl carrier f2 having a
sleeve-like hub f³ to embrace the stud e³, said pawl carrier having on its side nearest
the disc C¹ a roll f' to be acted upon by a species of tappet cam f.
A housing on the pawl carrier receives a spring 81, which, resting at its lower
end on a fixed part of the head, maintains the roll fin engagement with the tappet
or quick motion cam. f.
The pawl is governed as to its engagement with the lever e² by a pawl con-
troller, shown as an arm pivoted to the lever c² and having a beveled lug f³ and
a notch on its upper side near its extremity, to co-operate with a tooth fx on
the side of the pawl f, a spring 82 pressing the controller towards the said tooth, as
shown in Figure 5.
Now when the machine is started by raising the clutch rod C7 the surface or edge
cam c will swing the lever c² to the right, Figure 5, so that the tooth f* of the
pawl will enter the notch f of the pawl controller f, thereby drawing the pawl
out of the notch e of the lever e², and holding it disengaged when the pawl
carrier frocks to the left as the tappet cam f5 rotates, leaving the outer end of the
lever e² free to be depressed, to thereby cause disengagement of the pawl d from
the rack bar 5, permitting the spring B to act to raise the horn and clamp the
stock.
As the roll el enters the part of the cam groove e between the points 4 and 3 it
will be drawn towards the centre of the cam, to lift the link e, and by the pawl d
and rack bar d³ to lower the horn, releasing the stock to be fed, and as the roll
passes a point about midway between the point 4 and 3 the roll el is positively moved
to depress the link e and again cause the stock to be clamped, the circular part
between 3 and 2 maintaining the roll stationary with the horn elevated.
While the lever c² is held out to the right, as described, as it may be by keeping
the foot on the treadle C8, the horn will be automatically raised and lowered as
described, at each revolution of the disc C¹, and the pawl f will be maintained in
inoperative position.
If, however, the treadle C8 is released after the machine has been started the lower
part 9 of the edge cam c will permit the lever c² to swing to the left sufficiently to
release the clutch, and thereafter the roll c¹ passes to the still lower portion 10,
applying the brake c¹³ and moving the pawl f, by means of the notched pawl con-
troller, into position to engage the notch es of the lever e².
As the pawl carrier 2 is depressed by the tappet cam f5 the pawl will act to elevate
the outer end of lever e² and thereby the horn will be positively depressed as the
machine comes to a full stop.
The horn is thereby lowered a uniform distance beyond what is necessary to effect
the feed of the work on the horn, and the machine is stopped with the horn in its
extreme lowered position so that the work may be taken off and put on the horn,
the brake mechanism being adjusted to stop the rotation of the shaft when the point
of greatest throw of the cam f5 is acting to lower the horn a uniform distance
beyond what is necessary to permit the feed of the work.
The machine, therefore, is always in readiness to receive the stock, or to permit its
ready removal, before or after nailing respectively and the depression of the treadle B10
by the operator to lower the horn is obviated.
Referring to Figure 5, it will be seen that there is a slight clearance between the
roll e and the inner wall of the cam groove e between the points 2 and 4, and this is
provided to allow the stiff spring s² to lift the bevelled lug f8 of the pawl controller f
against the teeth of the pawl f, to cause the latter to be moved out of the notch e
when the operator depresses the horn to insert a thicker piece of work, so that the
lever e² is released to enable the pawl d and rack bar d to be first disengaged and
then engaged at the proper point corresponding to the thickness of such stock, when
the machine is next started.
5
The roll f is preferably mounted eccentrically on a stud 10, Figure 5, so that wear
may be compensated for, as it is important that the movement of the pawl carrier f¹

page_text: and the lever e² be timed accurately to follow each other in their motions at just the
right instants.
A measuring leg a, Figures 1 and 3 has adjustable thereon a collar a¹, adapted to
descend against a stop a on the head A¹ and guiding the measuring leg, the extent
of longitudinal movement of said leg determining the length of the nail or fastening
to be cut from the wire-like material, such adjustment being made by the
operator.
The leg a is connected with an arm of a pawl carrying sleeve a² which has a
second arm a³ provided with spring-pawls a, see Figure 4, which act on a ratchet
wheel a connected to a feeding wheel a peripherally scored or serrated to engage
and feed the wire-like material w used, which latter is pressed against said wheel by
a presser wheel a mounted in a yoke as adjustably attached to the head by a
screw a⁹.
When it is desired to stop the feeding of the wire for any purpose, without
stopping the entire machine, a feed stop, shown in Figures 1 and 4, as an arm 75
pivotally mounted in a part of the head A¹, is swung up into dotted line position in
said Figure beneath the arm a³, preventing its descent to enable the pawls a² to
engage a new portion of the ratchet wheel."
Normally said stop 75 is swung down into inoperative position, shown in full lines
Figure 4.
The periphery of the presser wheel a7 is grooved and serrated suitably to engage
wire-like material of any desired shape in cross section, said groove also aligning the
wire with the passages below.
It will be obvious that the back stroke of the pawls at is regulated by the position
of the collar a¹ on the measuring leg, to effect at their next forward stroke a
greater or less rotation of the feed wheel, to provide for the desired length of
fastening.
A third arm of the sleeve a² has a suitable roll 10, see Figure 3, acted upon by
a cam a¹² on a disc a¹³, having a flat portion a¹, which permits the roll to move
freely more or less when the pawl carrier is moving on its back stroke to assume a
starting point, the roll moving a distance in accordance with the adjustment of
the measuring leg a before the rise a40 engages and lifts the roll to thereby effect
the feed.
When the wire is fed forward more or less by such movement the cutters, to be
hereinafter described, are actuated to cut or sever a portion of the wire to form the
nail or fastening to be driven.
The edges of the cutters which engage and sever the wire are bevelled, and their two
edges are brought together in the wire.
Now if the wire be held rigidly by the feed mechanism during the cutting the
bevelled edges of the cutters will have to not only cut into but also compress the
wire, and a very great strain will be put upon not only the cutters but their actuator
mechanism as well.
On the contrary, if means are provided for permitting the wire to nove in a retrograde
direction slightly as the edges of the cutters enter it, the strain upon them and their
actuating mechanism will be greatly reduced.
I have herein provided such means by cutting away the cam a12 at a 45 at the
end of the feed portion a, Figure 3 so that as the cutters enter the wire to sever it
the roll a10 will enter the depression a5 and thereby the pawl carrier is permitted to
move back slightly, releasing the wire sufficiently to allow it to be moved backwardly
by the action of the cutters.
Such release of the feed, as it may be termed, does not cause a disengagement
of the feed wheel and wire but only allows a slight retrograde movement thereof.
A strong spring S2 depresses the measuring leg as clearly shown in Figure 3 and
maintains the roll ao in position to be acted upon by the cam.
The wire guide is shown in Figure 4, as two plates b, b', the former provided
next the plate 61 with a guide groove shaped to correspond substantially to the

page_text: cross section of the fastening material, the lower end or plate 61 having a steel wear
plate b³.
The driver bar 64 has attached to it a driver 65, Figures 1 and 9, which enters a
driver passage in a guide be suitably attached to the head of the machine.
The awl h is attached to an awl bar not shown, as forming no part of the invention
reciprocated by an arm h¹ forming part of a two armed lever mounted on a stud h²
and having a second arm h³ provided with a suitable roller or other stud h¹ which
enters a groove in the outer face of a cam hub h5 fast on the outer end of the main
shaft C.
The awl bar shank slides vertically in a rocking frame i having a sleeve-like
hub embracing a hub surrounding the main shaft in front of the cam disc a¹³.
The stock is fed while the awl is in it by means of suitable devices forming no part
of this invention, but which will be described briefly.
A movable side guide is attached to the front side of the rocking frame, and
at the rear of said frame is attached a guideway having a moveable side ³ in which
guideway is placed a swivel block 4, see Figure 3, entered by a pin 80 extended
from a dovetailed slide 5, toothed at one side, and fitted into a passage in a rocking
arm, connected to a short rock shaft having an arm provided with a roll
which enters a cam groove 28 at the outer side of the disc a¹³, see Figure 3,
the rock-shaft by engaging the sliding block, moving the rocking frame to effect the
feed.
A stud gear 80 on the arm * engages the teeth of the slide i³ and moves it
relatively to said arm and rocking frame to alter at will the length of feed.
The main shaft C has a cam / provided peripherally with a groove in which
enters a roller or other stud of a toothed lever ¹, pivotted at its upper end on an
eccentric stud 90 on the head, the lower end of said lever having, see Figure 9, rack
teeth to engage the teeth of a block 2, having extended loosely through it the reduced
end of a shaft 3, the block 2 being held securely on said shaft by a nut 95.
The shaft end le is provided with a longitudinal hole with a flaring outer end,
to receive a screw bolt k' having a conical head, the end of the shaft being split
the shaft to the proper
at ko, so that when the nut 95 has been turned up on
point to prevent endwise movement in the block tightening of the screw bolt k
will clamp or lock the nut, so that rocking of the shaft c³ will not loosen it.
It will be noticed by referring to Figure 9, that the block k² slides in a bearing in
the frame or head A¹, and that there is a clearance * between the upper side of the
shaft and the block.
As the block wears on its under side it moves away from the toothed lever k¹, the
clearance permitting such movement, and by turning the eccentric stud 90 on which
said lever is mounted it is lowered to maintain its toothed end in proper engagement
with the block, a set screw 105 normally holding the stud elainped.
The forward end of the shaft 3 has attached to it a suitable throat k7, into which
the wire or wire-like material is fed from the wire guide, and when a fastening or nail
has been cut off the throat is moved with the fastening into the driver path, the
lever effecting such longitudinal movement of the throat.
As the wire passage is inclined, and the driver path is vertical, the throat must be
tipped slightly in moving from one to the other, and this is effected by means of a
sleeve embracing the shaft 3, and slotted longitudinally to receive a spline ko
which enters a longitudinal groove in the shaft, so that oscillation of the sleeve
will be imparted to the shaft without hindering longitudinal movement of the
latter.
A lever 13, split at its end at 14, see Figure 10, is mounted upon the sleeve k8 and
receives a portion of the spline 10, a suitable screw bolt 1 clamping the lever 13
upon the sleeve and thereby holding the spline tightly and the lever 13 having a
roller or other stud to enter a cam groove at the rear side of the disc a¹³.
The moveable cutting blade m, Figures 1 and 4, is held in adjusted position on an
arm of the sleeve k8 by means of a cap plate m¹ and screw m², while a screw m³
longitudinally moveable in said arm bears against the outer end of the cutter, so

page_text: that it may be readily moved inwards as desired without partially dismembering the
machine.
The stationary cutter m², see Figures 1 and 4, is held between the head of the
machine and a detachable cap m5 by a suitable set screw me, and when the wire-like
material has been fed into the throat the sleeve is rocked, causing the moveable
cutter to pass the lower end of the wire guideway and cut the wire off, the throat at
the same time being tipped into substantially vertical position, to thereafter be moved
forward under the driver to enable the latter to strike the nail or fastening and drive
it from the throat into the work.
During the forward movement of the throat containing the loose fastening the
lower end of the latter may ride over a suitable foot or presser n, shown separately
in Figure 7, until it comes over the awl hole n³ therein, through which the fastening
passes to the work.
Referring to Figures 7 and 9, the foot or presser n is recessed on its upper side at n²,
and a large hole 3 and two smaller holes n' (Fig. 9) and n³ (Fig. 7) are drilled
through the presser.
A spring plate or cover no having holes n7 and n³ punched therein to leave rims or
burrs on the underside, to enter respectively the holes ³ and n', is held in the
recess n² between the presser and the adjacent portion of the head A¹, as shown in
Figure 9, the burr or rim n³ forming a pivotal point for the cover plate.
Normally the cover plate is in the position shown in Figures 7 and 9, with its front
end covering the holen, and held in place between the presser n and the adjacent
part of the head, but if the operator desires to adjust the cutters, he stops the wire
feed and moves the plate n to one side, until the hole n is uncovered, and he then
can insert from below a piece of wire to be acted upon by the cutters, until the
desired adjustment is effected, thus obviating waste of the wire and a tedious feeding
thereof little by little.
In the modification Figures 8 and 8ª, the presser or foot n has a single hole made
therein to receive a rotatable block 10, upset at its ends to retain it in place, and
having an eccentric hole 12 therethrough normally in the position shown in Figure 8,
but by giving the block a partial rotation the hole 12 is brought into position to
enable a piece of test wire to be inserted for use in adjusting the cutters.
Referring to Figures 1, 11 and 12, I have pivotted a support or arm o on a stud o¹
of the head or frame, and acted upon by a spring pin 02 when in the position shown
to retain it elevated, the outer end of said arm forming a bearing for a transverse
rotatable stud 03, which receives eccentrically a screw pin of extended through a
slot o in the upturned end of the edge gauge o®.
A spring washer o* is interposed between the head of the screw pin of and the
end of the gauge, to press the latter firmly into the preferably recessed face of the
stud bearing, rotation of the stud 03 by means of the slot and pin connection moving
the gauge o longitudinally towards or away from the front of the machine, below
the foot or presser n, the spring washer o* holding it in adjusted position.
A rod o held by screws 68 in the stud bearing is bent at its ends to form limiting
stops for the extreme longitudinal movement of the gauge.
When it is desired to nail across the sole of a boot or shoe the arm or support o
may be turned down on its fulcrum o' entirely out of the way.
The head of the machine has rigidly secured thereto a laterally extended arm r,
upturned at its outer end and cupped out at 1 to form an annular race for a series
of anti-friction rolls *, upon which rests the lower end of the hub 72 of the reel,
said reel being held in place by a pin 3, see Figure 13, extended loosely through
the hub and into a hole in the end of the arm .
As herein shown the reel consists essentially of an annular bottom plate and a
series of arms radiating from the hub 2 and downturned at their ends to meet the
plate 5, the reel being shown as a single casting.
One of the arms, as 70, is not connected to the bottom plate, to thereby leave a
peripheral opening through which the coil W of wire or wire-like material wis

page_text: inserted to rest upon the bottom plate, a removeable pin then preventing removal
of the coil.
The wire is drawn from the interior of the coil through the open centre of the
plate 5, and thereby carries the reel to rotate freely in a horizontal plane about its
vertical axis, and as the wire passes to the fixed guideway the fixed rotation of the
reel about a fixed vertical pivot prevents twisting of said wire.
In Figure 13 I have shown a guide roll 720 mounted horizontally at the side of the
arm r, adjacent the bottom of the reel, the wire passing under such guide roll as it
leaves the coil and having a partial turn given to it to position it for the feeding
devices.
My correspondent has so arranged the operation of the clutch, brake, and driving
mechanisms that the clutch is first released, and then later on the brake is applied,
the momentum of the main driving shaft after unclutching being taken up and
utilized by the driving mechanism and by the horn depressing devices, so that when
the brake is applied there is very little resistance to overcome and the machine
will be stopped immediately without undue shock.
From the foregoing it will be obvious that the horn is periodcally depressed, when
the machine is in operation from dotted line position Figure 1, to full line position,
to unclamp the work in order that it may be fed by the awl, and that the horn is also
finally depressed into full line position at the stoppage of the machine, whether a single
nail or fastening or any number be driven, and the mechanism employed for periodically
depressing the horn also operates when the horn is finally depressed, but in the latter
case independently operating controlling devices are brought into operation to govern
the final depression.
Both the periodical and final depression of the horn are automatic, and the machine
when stopped is always in position to have the work removed, and consequently the
machine is always ready to receive work without obliging the operator to first lower or
depress the horn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a nailing machine, a main shaft, a clutch therefor and a brake, controlling
means governed by rotation of said shaft to release the clutch, nail driving devices to
derive their final movement from the main shaft after release of the clutch, whereby
