Improvements in and relating to the Machinery for Inserting Metallic
Fastenings in Making Boots, Shoes, and the like.
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 is intended as an improvement on the class of machine repre-
sented in the Specification of Patent No. 1492, dated Jan. 24 1893.
In the machine described in said patent, suitable grippers located in a rotating
spindle are made to grasp and feed the wire intermittingly through said spindle
into the stock resting on a horn.
The feeding of the wire is effected by or through the action of a face cam acting
upon a roller or other stud of a lever, said face cam forming part of a hub fast
on the main shaft, and the mechanism of said machine is so organized, that said
lever may have imparted to it a greater or less back stroke to move the roller or
other stud of said lever toward said cam, that depending upon the thickness of
the stock lying on the horn and between it and the usual nose of the machine,
the length of the movement of said lever into the space of said face cam deter-
mining the length of the fastening to be inserted in the stock at the next feeding
aovement, thus enabling the fastening to be adapted to varying thickness of
stock on the horn.
In the machine referred to, when a shoe has had the proper number of fasten-
ings inserted in the sole thereof, and the shoe is ready to be removed from the
horn, the operator will turn a stop and put it into position to prevent the further
feeding of the wire, and at such time the lever, instrumental in moving the wire
feeding mechanism, is stopped in such position as to keep the grippers engaging
the wire in their depressed position, so that they cannot rise to again grasp and
feed the wire until said stop is turned aside into its normal or operative position.
The cam shaft having the cam for imparting movement to the lever of the wire
feeding mechanism, as well as the spindle carrying the grippers of said wire
feeding mechanism, are rotated continuously and do not stop when a shoe is being
removed from the horn and another one is being put in place.
A new shoe having been applied to the horn, the operator moves the stop in
the opposite direction, which immediately causes the roller or other stud of said
lever to be again put into operative position with relation to said face cam, so
that the cam may operate and move said lever to again start in motion the feeding
of the wire.
If, however, the change of position of this stop is not made while the roller
or other stud is opposite a high part of said cam face, and before the depressed
part of said cam arrives opposite said roller or other stud, to let the spring
co-operating with said lever turn it to lift the grippers and put them into position

page_text: to grasp the wire, then the fastening made at the first descent or feeding movement
of the wire will be too short.
Owing to the very rapid speed at which this machine is run in use, it has been
found practically impossible to ensure that the first fastening to be inserted upon
starting to feed the wire, said feed having been temporarily suspended, is of the
proper length, and consequently, one part of the invention to be herein described
has been devised especially to ensure that the wire feeding mechanism when
started will enable the first fastening inserted into the stock, which may be a shoe
sole to be of exactly the proper length.
In this my invention it is managed to so thoroughly control the stopping and
starting of the feeding of the wire that I may insert one or any desired number
of fastenings, one after another at any desired intervals of time apart, or, in
other words, I may control positively the insertion of each and every fastening,
and stop the machine after driving any fastening, and make the next fastening
of the proper length.
In the class of machine herein referred to, it has been customary to continue
in operation the cutting mechanism for severing the wire, notwithstanding the
fact that the wire feeding mechanism had been stopped, and owing to the rapid
operations of the machine, the cutters are apt to strike one against the other and
become thereby dulled or broken, and, consequently I have herein made provision
to automatically change or modify the motion of said cutters or the operation of
the wire cutting mechanism may be stopped entirely whenever the feeding of the
wire is suspended.
In practice, the face cam employed in the machine referred to has a small pro-
jection (said projection being herein retained) which gives to the lever employed
to effect the feeding of the wire, a quick start upwardly for an instant just at
the completion of the feeding movement of the wire, and just as the cutters are
opciating to sever the wire, said quick start being for a period just long enough
to partially release the wire just as the cutting mechanism is operating, the tem-
porary releasing of the wire preventing the formation of a head or burr upon
the end of the wire.
This burr, it will be understood, would be readily formed by the cutter blades,
their edges being bevelled, if there was any downward movement whatever given
to the wire during the cutting operation.
In the machine referred to, the operation of the lever for effecting the feeding
of the wire was suspended by or through the locking in a stationary position
of the socalled leg lever employed in the train of mechanism for controlling the
length of the fastening, but said lever was not moved far enough to put it entirely
out of the range of movement of the small projection referred to of said face
cam, and consequently, said small projection struck the roller or other stud of
said lever at each rotation, which resulted in the rapid wearing away of said pro-
jection.
In the invention herein contained, there is provided means whereby the said
lever for operating the wire feeding mechanism, when thrown out of operation
to suspend the feeding action, will be removed entirely from the range of move-
ment of any and all of the projections of the cam face referred to, so that in
the rotation of the main shaft with the said cam, while the feeding operation
of the wire is suspended the said cam will not be at all worn.
There is also, in the machine to be herein described, provided means whereby
the horn may be depressed at each descent prior to feeding the stock, not only
for a variable distance from a base line, the underside of the stock resting on the
top of the horn, to thereby relieve the stock, no matter what its thickness, from
the pressure in order that it may be fed; but said horn has given to it at each
descent sufficient additional movement to enable its tip, if the horn should be
left down at any descent, to stand in a position to enable the work to be taken off
from the hom.
The continuously rotated spindle is also provided with novel feeding grippers

page_text: or rollers to be described, said rollers being carried by a sleeve which is made
vertically movable outside said spindle, and rotating with it, the rollers, pre-
ferably three, entering slots in the forked end of the spindle and gripping between
them the wire at the centre of the spindle at the downward movement of the
sleeve to thus feed the wire, the rollers rolling over the wire as the sleeve rises.
To enable the machine referred to, to operate as described there is provided a
peculiar shaped lever, which I have designated as a manually controlled switch.
This switch or lever is mounted to turn about a horizontal stud, whenever one
of two lugs extended therefrom is struck by either one of two lips of a latch which
is reciprocated constantly in a vertical plane between said lugs, said lever being
turned in one or the other direction according to which lip it is desired shall
meet a lug.
The position of this latch is controlled by the foot of the operator put onto a
treadle or equivalent device, and by the movement of the latch to the right or left,
the switch or lever may be instantly moved to stop or to start the several mech-
anisms controlled simultaneously by said switch or lever.
The switch or lever has a slot which receives a pin extended from a lever having
a finger, said finger lever being mounted on or cooperating with the lever
employed in said patent for operating the wire cutting mechanism, so that when
said lever is in one position said finger will be put in the path of movement of a
cam and cause the lever to be moved to effect the severing of the wire, but when
said switch or lever is in its other position, the said finger is put out of position
with relation to the usual cam for operating it, 'and the cutting mechanism
remains at rest.
The switch or lever also has connected to it a rod provided with a locking block
having a hole through which is extended the lower end of the measuring leg
common to said patent, said measuring leg having a projection which in one posi-
tion of said switch or lever will be made to meet said block and suspend the feed-
ing motion of the wire, but in the other position of said switch or lever, said
measuring leg will be free to be moved.
This measuring leg when arrested by the said block, as when the wire feed is to
be stopped, leaving the spindle, however, rotating rapidly at usual speed, serves
to put the roller or other stud of the lever which reciprocates the feeding sleeve
provided with the roller, or it may be, other usual grippers, out of position with
relation to its usual acting cam.
This same switch or lever is also provided with a locking device shown as a
pivotted arm which when the feeding of the wire is to be suspended, meets the
shoulder of a locking plate attached to the lever employed in said patent for
effecting the lowering of the horn, and stops said lever with its roller or other
stud out of range of its actuating cam, the movement of the switch or lever in
its opposite direction removing the said locking device from said locking plate,
permitting the said roller stud to be again struck and moved by its cam to depress
the horn during the feeding of the stock or work over it.
The upper or top surface of the locking block is beveled or inclined, so that
when said block is pulled fully under the projection carried by said measuring
leg, the lever actuated by the rotating cam to reciprocate the feeding sleeve will
be so far moved as to put its roller or other stud wholly out of the range of its
actuating cam, it being understood that the main cam shaft and spindle continue
to run at high speed even when the wire feeding mechanism, the wire cutting
mechanism and the horn remain at rest, as when putting a shoe on the horn, or
removing a shoe from the horn.
In another application for Letters Patent No. 6971 left by me on the 22nd day
ments, and for always depressing the horn into its lowest position when the
of March 1898, I have described means for imparting to the horn certain move-
machine is stopped and the work is to be put into or be taken out of the machine.
In the application referred to, the spool carrying the wire was mounted on a

page_text: pin made heaviest at its point, and said pin was intended to be kept fully seated
by or through centrifugal action, but in practice it has been found that some-
times the operator by carelessness fails to push the pin in far enough, and when
the spindle is started at its rapid speed, the pin is thrown out, causing much
damage.
To provide against any liability of accident due to the failure of the pin being
properly seated, the yoke at the upper end of the spindle in which the spool is
placed is provided with a locking device which is under the control of said pin,
and if the pin is not fully inserted, so that its tapered head acts to lift the said
locking device, then the spindle cannot be rotated, for the reason that the head
of said locking device will strike against a suitable stop, forming a part of the
fixed portion of the frame work.

Improvements in and relating to the Machinery for Inserting Metallic
Fastenings in Making 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 is intended as an improvement on the class of machine repre-
sented in the Specification of Patent No. 1492, dated January 24th, 1893.
In the machine described in said patent, suitable grippers located in a rotating
spindle are made to grasp and feed the wire intermittingly through said spindle
into the stock resting on a horn'
The feeding of the wire is effected by or through the action of a face cam acting
upon a roller or other stud of a lever, said face cam forming part of a hub fast
on the main shaft, and the mechanism of said machine is so organized that said
lever may have imparted to it a greater or less back stroke to move the roller or
other stud of said lever toward said cam, that depending upon the thickness of
the stock lying on the horn and between it and the usual nose of, the machine,
the length of the movement of said lever into the space of said face cam deter-
mining the length of the fastening to be inserted in the stock at the next feeding
movement, thus enabling the fastening to be adapted to varying thickness of
stock on the horn.
In the machine referred to, when a shoe has had the proper number of fasten-
ings inserted in the sole thereof, and the shoe is ready to be removed from the
horn, the operator will turn a stop and put it into position to prevent the further
feeding of the wire, and at such time the lever, instrumental in moving the wire
feeding mechanism, is stopped in such position as to keep the grippers engaging
the wire in their depressed position, so that they cannot rise to again grasp and
feed the wire until said stop is turned aside into its normal or operative position.
The cam shaft having the cam for imparting movement to the lever of the wire
feeding mechanism, as well as the spindle carrying the grippers of said wire
feeding mechanism, are rotated continuously and do not stop when a shoe is being
removed from the horn and another one is being put in place.

page_text: A new shoe having been applied to the horn, the operator moves the stop in
the opposite direction, which immediately causes the roller or other stud of said
lever to be again put into operative position with relation to said face cam, so
that the cam may operate and move said lever to again start in motion the feeding
of the wire.
If, however, the change of position of this stop is not made while the roller
or other stud is opposite a high part of said cam face, and before the depressed
part of said cam arrives opposite said roller or other stud, to let the spring
co-operating with said lever turn it to lift the grippers and put them into position

ment of the wire will be too short.

stopping and starting of the feeding of the wire that he may insert one or any
desired number of fastenings, one after another at any desired intervals of time
apart, or, in other words, he may control positively the insertion of each and
every fastening, and stop the machine after driving any fastening, and make the
next fastening of the proper length.
In the class of machine herein referred to, it has been customary to continue
in operation the cutting mechanism for severing the wire, notwithstanding the
fact that the wire feeding mechanism had been stopped, and owing to the rapid
operations of the machine, the cutters are apt to strike one against the other and
become thereby dulled or broken, and, consequently, I have herein made provision
to automatically change, modify, or it may be stop entirely the operation of the
wire cutting mechanism whenever the feeding of the wire is suspended.
In practice, the face cam employed in the machine referred to has a small pro-
jection (said projection being herein retained) which gives to the lever employed
to effect the feeding of the wire, a quick start upwardly for an instant just at
the completion of the feeding movement of the wire, and just as the cutters are

the end of the wire.
This burr it will be understood would be readily formed by the cutter blades,

to the wire during the cutting operation.
In the machine referred to, the operation of the lever for effecting the feeding
of the wire was suspended by or through the locking in a stationary position
of the so called leg lever employed in the train of mechanism for controlling the

cam, and consequently, said small projection struck the roller or other stud of
said lever at each rotation, which resulted in the rapid wearing away of said pro-
jection.
In the invention herein contained I have provided means whereby the said
lever for operating the wire feeding mechanism, when thrown out of operation
to suspend the feeding action, will be removed entirely from the range of move-
ment of any and all of the projections of the cam face referred to, so that in
the rotation of the main shaft with the said cam, while the feeding operation
of the wire is suspended, the said cam will not be at all worn.
The machine to be herein described is provided with means whereby the horn'

page_text: may be depressed or lowered prior to feeding the stock, it being lowered. after
inserting each fastening for a variable distance from a base line, which may be
the underside of the stock resting on the top of the horn, this depression or
lowering of the horn relieving the stock from pressure no matter what its thick-
ness in order that the stock may be fed over the horn.
The machine is to be stopped after the wire feeding device is stopped, and
when so stopped the tip of the horn is put into a lower position than that occupied
ordinarily by it when lowered. to permit the feeding of the wire over the horn.
To effect this additional depressing or lowering of the horn in order that when
it is at rest the tip of the horn may be so located as to enable the operator to
remove the shoe a lever constituting the first of a train of devices to be described
for automatically depressing the horn, is locked in its highest position, and there-
after the cam for operating said lever operates to effect a greater extent of depres-
sion of the horn than previously done.
I have also provided the continuously rotated spindle with novel feeding grippers
to be described.
The particular features in which this invention consists will be hereinafter more
fully described, and specified in the claims at the end of this specification.

To simplify the description of the operation of the parts herein, I will state
that the column A, the head or frame part A* mounted thereon, the main shaft B
having at one end a worm gear d, and at its opposite end a toothed gear d
which engages a toothed gear ds on a parallel shaft d, the opposite end of said
shaft having a like worm toothed gear de, both of said gears being engaged by
a worm do on the exterior of the continuously rotating spindle A10 having fast
upon its upper end the driving pulley A, embraced by a continuously rotating
belt supported on the sheaves A8 and driven from any suitable power, so that
said spindle rotates simultaneously the said two shafts B14 and d; the cam D17
fast on said shaft G, and also the cam. B¹³ secured to said shaft and having two
toes C¹ and C³; the lever C mounted loosely on a stud B15, said lever having a

page_text: downwardly extending toe resting against a stop C, an arm of the said lever
having a stud C³ to which is connected a link C, the lower end of said link being
connected by a bolt 116 with an arm C having its hub split and clamped by a
screw 117, shown by dotted lines, upon a hollow rod or rock shaft C, instrumental
in moving the carriers or arms 121 and 123, each having a suitable cutter blade
or knife 128; the rod 113 sustained in a yielding manner by a spring 112, the
upper end of said rod acting against the lower side of the lever C, the lower end
of said spring resting on a fixed part of the head A*, the lower end of said rod
entering a threaded nut 114 rotatable in said fixed part of the head; the set
nut 115 to secure said threaded nut in its adjusted position; the lever B° having
one of its arms extended and provided with a roller or other stud B10, said lever
being fulcrumed on the stud B15 and adapted to be actuated by the face of a
cam e cut in one side of the cam hub B3, shown by dotted lines in Fig. 4; the
lever e¹ pivotted at ea and having at its upper end a roller or other stud e entering
a suitable cam groove et at the rear side of the cam hub D", said lever being
slotted at its lower end to embrace a suitable stud or device carried by one arm
of a lever e, having at its opposite end a segmental series of teeth 30 engaging
a series of teeth in a hub mo, mounted loosely on a shaft m³, said hub having an
attached pawl carrier m19 provided with a pawl m20, which in the reciprocations
of said pawl carrier engages the teeth of a ratchet m30 fast on the shaft m³ on
which the said toothed sleeve is mounted loosely; the spring 165 to back up one
end of said shaft m³, the box m' in which said shaft m³ is located, the feed
wheel m¹ mounted on a stud 45 of said box and deriving its rotation from teeth
at the end of the shaft m³, the toothed pinion-like bolt 170 to move the sleeve m*
back and forth to locate the wheel m¹ at the proper distance from the nose,
according to the distance it is desired to insert fastening from the edge of the
sole; the yoke D10 embracing loosely the sleeve F of the spindle and toothed to be
engaged by teeth of the lever 114 the chief lever of the wire feeding mechanism,
it being pivotted at D15 and having an arm provided with a roller or other
stud D, which is acted upon by the cam face of the hub D17; the stud screw G
mounted in one end of the said lever D14 and having connected with it the
measuring leg G³ provided at its lower end with an adjustable nut or shoulder 40;
the measuring rod G¹ connected with a suitable arm G extended from the horn
shaft B', free to slide up and down in a sleeve B forming part of the column, the
horn B having a holder B30 surrounding loosely the upper end of the horn spindle
so that the horn may be rotated thereon; the spring 100 to keep the roller D16
against the face cam D"; the stud, 103 supporting the devices holding the said
spring 100, the bearing D7, the rod B2 connected with the lower end of the horn
spindle, the spring B which acts normally to elevate the horn against the under-
side of the stock to clamp it between itself and the nose f, and two treadles or
levers B32 and B3 to a part of which said rod B2 is connected, are and may be all
substantially as described in said Specification No. 1492 of 1893 so that parts need
not be herein further referred to, it being supposed that the improvements now
about to be described have been put substantially upon that machine, doing
away, however, with some of the parts. In the specification referred to, the
lever B, the first of the train of devices employed for automatically depressing
or lowering the horn after inserting each fastening in order that the stock may
be fed over the horn, is shown as connected directly by a rod with the lever B³;
but herein the said lever B9 and the lever B³ are connected by a rod BB having
attached to it a carrier d³ provided with a toothed plate b adapted, when the rod B
is lifted, to engage ratchet teeth at the upper end of a rod de connected to the
lever B³, joined to the lower end of the horn spindle, said rods when lifted effect-
ing the depression or lowering of the horn immediately after the insertion of each
fastening to enable the stock to be fed, as stated, over the horn.
The hollow spindle A10 receiving the screw threaded wire has screwed into it
at its lower end a split extension or nose A10*, said extension presenting three
yielding fingers.

page_text: The sleeve F surrounding this spindle and raised and lowered for the wire feed-
ing operation is surrounded loosely by the yoke D10, and the lower end of this
sleeve is enlarged as at F¹, and the lower side of said enlargement is cut out as
at 12 to leave an annular chamber with an inwardly inclined wall.
This enlargement has connected to it by suitable screws F³ a flanged cap or
hood F, the inclined part of said cap supporting the journals 2 of the wheels h¹o
corrugated at their peripheries to enter the grooves of the threaded wire.
There are three of these rolls, and they act to grasp and feed the wire as the
sleeve is moved downwardly, the journals of the said rolls being at such time
acted upon in a direction to force the peripheries of said rolls firmly against the
wire, but when the said sleeve is raised, the pressure of said rolls is quickly
released so that said rolls roll readily along over said wire.
The journals h of these rolls are conical to thereby enable them to readily
stand in the annular groove F2.
My correspondent is aware that prior to this invention rolls carried by short
arms or levers have been used to grip and feed wire, but he is not aware that a
plurality of rolls having journals at their sides have ever been mounted loosely
at or near the lower end of a sleeve, and that said sleeve has been provided with
an inclined or cam surface to simultaneously, positively and uniformly act on
said journals and force said rolls in gripping contact with the wire to feed the
same.
The invention herein contained is not however limited in all cases to the use of
the particular rolls referred to in the wire feeding mechanism, and instead I
may employ any other usual or suitable wire feeding grippers as part of the wire
feeding mechanism.
In this present invention the lever e¹ is represented as provided with an ear 20
carrying a stud ea upon which is hung loosely a latch or actuator 2, said latch
being herein shown as of T shape,-i.e., it has at one end two lugs t, t', one
projecting in one and the other in the opposite direction.
This latch has a lug f³ extended from one side of it in which is placed loosely
one end of a spring f, the lower end of said spring being fixed by a set screw fa
in a part of a lever f.
This latch rises and falls with each movement of the lever e¹, said lever being
moved at all times even when the wire feeding mechanism is thrown out of action.
The head A of the machine is provided with a small hub or bearing e³, shown
best in Fig. 1, it receiving loosely a stud e², shown by dotted lines in Fig. 4,
one end of said stud being screwed into a threaded hole in a switch or device
shown as a lever €26, said switch or device having two like lugs 27 and 28 which
are engaged at suitable times by one or the other of the lugs t, t', of the latch,
as will be described.
The stud e24 constitutes the fulcrum for the switch or device 26.
The switch or device 2 has a hole e29, which receives in it a stud e30, fixed to and
extended from one side of a locking device e, said locking device having at its
lower end below said stud 30 a bevelled pit which receives in it the upper end
of a spring pressed pine, said pit being shown by dotted lines in Fig. 4, and
also in Fig. 5^.
The shank of the said pin and the spring about said shank normally stand
in a hole in an ear e³, represented as projecting from one side of said switch e2.
The lever has a bored hole f which fits loosely over a stud f10, properly sus-
tained in a part of the head A, said lever having a heel f12 and two sleeve-like
portions f¹³ and f", each of said portions being bored centrally.to a greater or
less depth.
The part 3 receives in a bore extending but part-way through it, the upper
end of a rod f15, the lower end of which is connected to the rear end of a
treadle f15 made as a lever of the first order pivotted at f25 on the base of the
column, and adapted to be turned by the foot or it may be any part of the body
of the operator, whereby by depressing the front end of said treadle, its rear end

page_text: and the rod f15 may be lifted to move the lever f about its fulcrum fi for the
purposes to be described.
i
The part f is bored from its top partially through and receives a spring f",
the upper end of which, by acting on a portion of the head A³, serves to keep
the heel of the lever fi down against the upper portion A* of the said frame-
work A, leaving the lever f in its normal position, with the front end of the
treadle elevated.
The framework A* contains a notched plunger f18, shown in position in Fig. 6
and detached in Fig. 6, and a projection f18 of said plunger at one side of the
notch therein receives against it one end of a spring f, the opposite end of said
spring being connected in any suitable manner to the switch 22, it being shown
in Fig. 6 as connected to said switch by a suitable screw 20.
The lower end of the switch or device has a projection e26* which enters the
notch in the plunger f18.
The upper end of the switch or device e26 has a slot f2 which receives a lug or
projection 2 at the lower end of a lever-like movable finger f³, see Fig. 74, said
finger being mounted movably on a stud fcarried by the lever C, the upper
end of said finger having a projection 3 which may be struck, when said finger
is in its operative position, by one and then the other of the toes C and C³.
When the toes act on the projection 3 of said finger the lever C will be
depressed to operate the cutting mechanism and sever the wire.
The lever B is. provided with a locking plate or shoulder e, and said plate
may be secured to said lever by suitable screws or bolts so that said shoulder may
be engaged by the locking device €31.
The drawings Figs. 1 and 4 show the parts of the machine in the position they
will occupy when the main shaft B and its cams and the spindle A10 are running
at speed, but with the lever D¼ which imparts movement to the wire feeding
mechanism and the lever 13° for lowering the horn in their stationary inoperative
position with relation to their actuating cams, and the finger f is also in its
inoperative position, so that the cutting mechanism will not operate, but the
latch will be reciprocated in its position shown in Fig. 4, but the lug t, it
having at one rise of the latch met and turned the switch or device, will not
again meet the lug 28 of the switch or device to turn it, and consequently, said
switch will remain in the position shown in Fig. 4, and at such time the slot fal
of said switch will hold the end 3 of the finger f out of operation, and the lug t¹
of the latch as it rises will pass inside of the lug 27 of the switch.
During the time that the wire feeding mechanism is so held out of operation,
the feed locking block 9 occupies its position shown in Fig. 4, so that the nut 40
stands on the top of said block in about the dotted line position shown in Fig. 2,
and acting through said measuring leg the roller or other stud of said lever Di
tannot approach close enough to the said face cam to be moved thereby to feed
the wire, and said lever cannot be moved by said face cam until after the block 9°
has been moved to the right in Fig. 4 sufficiently far to let the circular lower
end of said nut or shoulder 40 enter freely the round hole glo in said block.
This block has connected to it at one end a rod g³ having at its opposite end a
hooked or notched part 97 in which enters a pin or projection 915 carried by the
lower end of the switch e26.
It will be understood that the switch or device 26 performs three different
operations, i.e., it determines when the wire feeding mechanism may be stopped
and started; it controls the finger f, so that the cutting mechanism may be
operated or not operated; and it controls the stopping and starting of the lever B⁹
for depressing the horn.
In Fig. 14 I have shown the lever C with a modified form of finger which I
will now describe.
The finger 3 corresponding with the finger 3 herein before referred to is located
in the end of the lever C and is adapted to be moved vertically into its operative
position by an eccentric 2 at the upper end of a lever p¹, said eccentric when in

its other extreme lowering said finger sufficiently so that said toes C¹ and C³,
although they meet the said finger, do not move the lever C far enough to enable
the cutting edge of the cutters to meet, and consequently they will not be dulled.
The operator, to start the wire feeding and other controlled parts of the
machine, will put his foot on the treadle fireferred to, and lift the rod f5 and
with it the lever f, turning the heel 12 of said lever upwardly away from the
lug 18 of the plunger f18, and instantly the spring 19 compressed by the
switch, occupying the position Fig. 6, will throw the said lug under the said
heel and between it and the framework of the head A*, thus preventing the
descent of the lever f7.
This movement of the lever through the spring fo turns the latch 22, said
latch it being understood being reciprocated vertically continuously.
This latch may be turned whenever the lever f7 is raised, no matter what the
position of the latch, whether it is being moved downwardly or whether it may
have been started partially upwardly, the lug t¹ then lying within the inner side
of the lug 27, the said lug finally getting under the lug 27 of the switch 26,
and after this lugt passes under the lug, then at the next
rise of the latch the said lug meets the lug and turns the switch or
device 26, it in its movement performing simultaneously three operations to be
described, and so long as the foot is kept upon the treadle, the said switch having
been moved once by the lug t¹, the switch or device will remain in that position
while the latch 22 continues to reciprocate, and during such operation the lug ti
will stop close to the lug 27, but will not again move the switch 26 until after
the foot shall have been released from the treadle, to enable the spring fo to
again turn the latch, this time to the left viewing Fig. 4, putting the lug t in
position to act at a subsequent rise of the latch against the lug es
Going back to the first rise of the latch with its lug t¹ under the lug e27
of the switch, the switch is turned, causing the locking device el to retire from
the locking plate or shoulder 2*, fast on or carried by the lever B, thus per-
mitting the roller or stud B10 of said lever to come within the range of movement
of its actuating cam surface e, and at the same instant the slotted part fl of
the switch moves the finger about its pivot f23, putting its end 3 against the
projection 4 of the lever C, so that the toes C¹ and C2 may strike successively said
end 3 and depress said lever to operate the cutters to sever the wire, and during
the same movement the pin g15 at the lower end of the switch 26, it standing in
a notched part 7 of the rod g³, connected with the feed locking block, is pushed
to the right viewing Fig. 4, enabling the nut 40 to drop into the hole go in the
said block, it, on entering the said hole, coming upon the top of and being placed
immediately under the control of the measuring rod G¹, common to the said
patent.
The devices so far described operate in such time and order that the switch e26
is moved to let the roller or other stud D16 of the lever D14, for actuating the
wire feeding mechanism, contact at first with some part of the high part of the
face cam D between the points 200 .and-201 and behind the extreme small pro-
jection 202 before referred to, and consequently the roller or other stud of the
lever D14, under the action of the spring 100, is always in readiness to enter promptly
the cam recess 203 of the said face cam for a greater or less distance, to raise
the sleeve to start the wire feeding, that depending upon the thickness of the
stock resting on the top of the horn, and consequently the wire will be fed always
just the proper length for the stock then 'on the horn and to receive the nail to
be made, said nail always being of just the proper length.
Should the operator remove his foot from the treadle at any portion of the
revolution of the shaft B, the latch will be instantly moved to the left, and
at its next rise, it will move the switch 26, so that it will instantly move the feed
locking block into position to catch and sustain the nut 40, this being done when
the grippers or feeding mechanism is at its lowest position in its down stroke,
and at the same instant the switch turns the projection 3 of the finger f22 aside

page_text: out of the path of movement of the toes C and C, to stop the cutting operation:
and while the roller or other stud B10 is on the highest part of its actuating
cam e, the locking device e³ immediately slips into and engages the locking
plate or shoulder, keeping the said roller or other stud out of contact with
the said cam and leaving the lever B at rest.
was
When the operator lifted the lever fi so to start the machine, the end of the
plunger was pushed immediately under the heel f13 by the spring f", and imme-
diately the rising latch met and turned the switch so that its lower end e26*
moved to meet the opposite side of the notch in said plunger, thus pulling the
end 18 out from under the heel f¹, and the switch remained in this position so
long as the operator desires to insert the fastenings without stopping the machine,
but when he desires to stop the machine, which may. be done at any fastening,
he has only to remove his foot from the treadle f15, thus letting the heel f¹ meet
the head A, and the lever f in its movement immediately causes said spring fo
to change the latch to again turn the switch, it compressing the spring 19.
It will be noticed, see Fig. 44, that the locking device acted upon by the spring
pressed pin will stand in its natural position, see dotted lines, and in such position
the acting end of said locking device will stand out of line with the centres e
and e, see-dotted lines X3, the end of said locking device in such position being
so located as to easily pass under and so as to readily engage the shoulder of
the locking plate on said lever B, and thereafter by the continued movement of
said switch the end of said locking device is brought into its full line position with
its outer corner in line of said centres, thus enabling the said locking device
to turn for a slight distance said switch just far enough to remove the roller
stud B10 out from contact with its actuating cam.
My correspondent believing that he is the first to provide means for automati-
cally and positively ensuring just the proper length for the first fastening to be
inserted when starting the machine, so that said fastening will be adapted exactly
for the thickness of stock lying on the horn, and believing that he is also the first
to.positively remove the roller or other stud of the lever instrumental in lowering
the horn out from contact with its actuating cam; and also the first in this class
of machine to temporarily shorten the stroke of or completely throw out of opera-
tion the wire cutting mechanism, I desire it to be understood that this invention
is not to be limited to the exact form of switch or device or of locking device or
of latch, shown and described, as the same results might be readily accomplished
by slight changes in construction without the exercise of other than mechanical
skill; nor, herein, by the term " treadle or "lever is this invention limited to
the precise form, shape or location of the treadle, and instead, by the term
"treadlo" as used in the claims, I intend to cover any other usual or suitable
lever or device adapted to be engaged and moved at the desired time by any part
of the body of the operator.

Herein it will be observed that the cam face e for acting upon the roller or
other stud B10 of the lever 139, instrumental in lowering the horn, is a single cam
face, whereas heretofore usually the said roll has entered a cam groove.
By employing this single cam face and the latch to engage the locking
plate or shoulder carried by said lever B9, whenever the feeding mechanism of
the wire is stopped, which may be done after driving each and every nail if
desired, or after driving any desired number of nails, it becomes possible, by lock-
ing the lever B in its highest position, a position a little higher than that in
which it is left by the action of the cam e on the roll 1310, to put the tip of
the horn always in its lowest position, a position lower than that occupied ordi-
narily by the tip of the horn when fastenings are being inserted one after the
other in succession.
When the horn it at rest and is fully lowered, to enable the stock to be
removed from the horn, the cam which effected the lowering of the horn con-
tinues to rotate, said cam not being stopped at all except when the operator desires
to completely discontinue the use of the machine.

page_text: "
By the term "manually controlled switch or device" or "manually controlled
latch or manually controlled lever f7" I mean devices which occupy during
the regular operation of the machine a certain position, and which are put into
such position by or through a special movement of the operator, and that to
suspend part of the operated parts of the machine said manually controlled
devices are again, moved by the operator entirely independent of and distinct
from the cam shaft of the machine.
The upper side of the locking block is made of cone shape or inclined, and it
is the highest part of said block next its outer or right hand end that acts to
fully place the roller or other stud D16 out of the range of the cam projection 202,
said cam projection being deflected on the cam hub D7 because said lub is large
enough to ensure the insertion of two fastenings at each rotation.
In the specification of patent referred to the spool carrying the wire was
mounted on a pin made heaviest at its point, and said pin was intended to be
kept fully seated by or through centrifugal action, but in practice it has been
found that sometimes the operator by carelessness fails to push the pin in far
enough, and when the spindle is started at its rapid speed the pin is pulled out,
causing much damage.
To provide against any liability of accident, due to the failure of properly
inserting the pin, I have provided the yoke with a locking device 85, which is
under the control of said pin, and if the pin is not fully inserted so that its
tapered head acts to lift the said locking device, then the spindle cannot be
rotated for the reason that the head of said locking device will strike against a
suitable stop 86 forming a part of a fixed portion of the framework.
