Similar letters refer to similar parts wherever they occur on the different
parts of the drawings.
In the drawings, A represents the frame or standard in bearings in which
is journalled the rotary driving shaft B from which motion is conveyed to the
different working parts as will hereinafter be more fully described.
On the upper portion of the frame A is made a horizontal slide A' on which
is longitudinally adjustable the arms CC on which the mechanism for feeding,
straightening and cutting off the wire is mounted, as well as the staple forming
and driving mechanism, as will hereinafter be more fully shown and described.
In the drawings Figs. 1, 2, 4, 5, 6, 7 and 8, D represents the box and D¹
represents the cover of the box which are to be hinged together by the improved
mechanism. The box and cover are clamped and held in position during the
driving and clinching of the staple hinges as follows:-At the front of the
frame A is located a vertically movable, angular table E El composed of a hori-
zontal portion Eupon which the cover of the box is supported, and a vertical
portion E suitably guided in ways on the vertical front portion of the frame A.
The said table E E is automatically movable upwards, preferably by means
of a continuously rotating cam disk e which actuates a lever el pivoted at e
and having pivotally connected to its forward end a nut containing an adjust-
able screw, the upper end of which bears against a rear projection on the
vertical table portion E¹ as shown in Figs. 2, 3 and 8.
By this arrangement, the angular table E E is automatically movable up-
wards, so as to cause the box and cover to be held firmly against the forward
lower portion C of the arm C C as shown in Figs. 2, 4 and 17 during the driv-
ing and clinching operation of the staples.
The table E E is automatically lowered by its own gravity when the came
ceases to act on the lever e¹, so as to permit the easy removal of the hinged box
and cover and so as to enable the operator to place successive ones in position
for receiving the staple hinges.

page_text: The cam e is secured to a shaft e journalled in bearings in the frame A, and
to it is secured a gear e meshing in a pinion es secured to the driving shaft B
as shown in Figs. 2 and 3.
On the horizontal table portion E is arranged a yielding gage F, against the
rear portion of which is made to bear a preferably leaf spring F which is secured
to a block F adjustable on the table portion E so as to compensate for varia-
tions in the width of the covers that are being hinged as shown in Figs. 1, 2,
3, 4 and 5.
A similar adjustable and yielding device is used for the support of the box
body D, and it consists of brackets G G preferably adjustable to and from each
other in a slotted bar G', which is supported on a preferable leaf spring C³ that
is secured to a block G³ adjustable on the table portion E¹, so as to compensate
for variations in the height of boxes that are being hinged as shown in Figs. 2, 7
and 8, and f¹ are adjustable side guides on the respective table portions E
and E and they serve as stops or guides against which the ends of the respec-
tive cover and box are placed, so as to locate said parts in their proper posi-
tions relative to the staple driving and clinching devices.
In bearings in the arms C C is journalled a shaft C2 which is set in a rotary
motion by means of the pinion on the driving shaft B, meshing in the teeth
of an intermediate gear secured to a shaft 61 journalled in the upper portion of
the frame A, the gear 6 meshes in a gear 03 secured to the shaft C and in this
manner a rotary motion is imparted to the said shaft C².
On said shaft C2 are splined a pair of longitudinally adjustable sleeves C+
(one for each of the staple making and driving devices) and to said sleeves are
secured the various cams for operating the wire feeding and straightening, cut-
ting off and pointing device, the staple forming device, the staple feeding device
for the formed staples, the staple driving device, the oscillating driver carrier,
the staple carrying device for carrying the formed staple into position below
the driver, and the box and cover clamping device, as will hereinafter be more
fully shown and described.
The clamping device for automatically clamping the rear side of the box
against the vertical portion E of the angular table and the cover against its
yielding gage is constructed as follows:-On the sleeve C are secured a pair
of cams H H (one for each staple driving device) each such cam during its
rotation comes in contact with the rear end of a link H' that is pivoted at its
rear end to a rocking lever H2, which latter is pivoted at its lower end on an
adjustable fulcrum H³ secured to the arm C as shown in Figs. 1, 5 and 25.
The forward end of the link H¹ is pivoted to the upper end of the clamping
lever H3 which is pivoted to the forward end of a longitudinally adjustable
bar H that is adjustably secured to the arm. C at h for the purpose of compen-
sating for variations in the thickness of the stock of which the boxes are made.
Within the inner face of the clamping lever H³ is secured a preferably steel
hardened clinching block h³ against which the pointed ends of the staple driven
through the box body are clinched during the staple driving operation.
ffare clinching blocks arranged in a groove f³ in the horizontal table
portion E against which the pointed ends of the staples driven through the cover
are clinched during the driving operation.
The clinching blocks f f are adjustable to and from each other so as to be
located corresponding in positions relative to the staple driving devices which
are likewise adjustable to and from each other according to the distance apart
in which the staples are desired to be driven, as will hereinafter be described.
his a spring which actuates the lever H2 so as to automatically release the
clamping lever H3 as soon as the cam H ceases to act on said lever H2 as shown
in Fig. 5. The automatic mechanism for feeding, straightening, pointing, and
cutting off the wire preparatory to forming the staples, is carried out
follows:
°
as
Each of the staple forming and driving devices receives its wire from a

page_text: reel I from which the wire is intermittently carried by the feed device, partially
around a loosely rotating grooved wheel 1' and from the latter between a pair
of straightening rollers 113 one or both of which may be adjustable, although
in practise it may be required to make one of said rollers adjustable as shown
in Figs. 2 and 4.
The wire is fed, cut off to the required length and pointed by means of a
pair of feed, cutting, and pointing levers It I pivoted at it to a slide I which
is set in a reciprocating motion preferably by means of a rod I pivotally con-
nected to said slide and actuated by a track cam I7 secured to the rotary sleeve C
as shown in Figs. 1, 2, 4, and 27.
The levers II are caused to impinge on opposite sides of the wire by the
influence of springs when the slide 15 is moved in the direction of the
arrow shown in Figs. 2 and 4. When the slide 1 is moved in an opposite
direction, the said levers I* I are released and made to slide freely back on the
wire, which during such backward motion of the slide I is held stationary
between a fixed block Is and a spring pressed brake I as shown in Figs. 2 and 4.
The wire is cut off and pointed as the slide I approaches the forward end
of its stroke by the levers 14 I coming in contact with stops 26 26 adjustably
secured to the arm C, by which, the said levers are caused to rock backwards
sufficiently to bring their abutting cutting jaws or surfaces in contact, by which
the wire is additionally pinched sufficiently to point and sever it at the
desired place according to length of staple required. By adjusting the position
of stops the length of the staple blanks are regulated according to the
thickness of the stock of which the boxes to be hinged, are made.
For the purpose of regulating the amount of feed of the wire, I secure in an
adjustable manner to the arm C a pair of blocks I10 I10, which, during the
return motion of the slide I come in contact with the upper ends of the
levers II causing them to be released from gripping the wire and held so
until the said levers are released from contact with said blocks I10 I10 during the
forward motion of the feed device.
The staple forming and driving device is carried out as follows:-In guides
in the forward end of each arm is arranged a female die or former K and a
male former K¹ the female die or former has a vertical perforation k for receiv-
ing the driver bar and at two opposite sides of such perforation are made longi-
tudinal recesses k¹¹for receiving the sides of the staple during the forming
operation as shown in Figs. 5, 9, 10, 11, 12 and 16.
K2 is a vertically movable plunger guided in ways on the arm C and to it
is imparted a vertical reciprocating motion by means of a lever K³ pivoted at k³
to the arm C and operated in one direction, to force the plunger down, by means
of a cam K secured to the rotary sleeve C and in the opposite direction by the
influence of a spring as shown in Figs. 2, 4, 5 and 28.
The forward end of the lever K³ is pivotally connected to the upper end of
the plunger K² as shown.
The lower end of said plunger K2 is connected to the female die or former K
in such manner as to permit the female die K to be laterally movable relative
to said plunger for a purpose as will hereinafter be described.
A lateral reciprocating motion is given to the male former by a lever K5
pivoted at to the frame C and operated in one direction by a cam K6 secured
to the sleeve C and in the opposite direction preferably by the influence of a
suitable spring.
To the male former K¹ is secured a pin or projection adapted to be received
in slots in the wings of the female die K as shown in Figs. 9, 10, and 11.
Said slots are vertical in their lower ends, and inclined in their upper ends as
shown, so as to permit the female die to descend during a part of its stroke, to
form the staple by bending it over the male former, without causing such
female die to move horizontally and during such staple forming operation, the

page_text: projection on the male former is received in the vertical lower portions of the
slots in the wings of the female die.
During the further descent of the female die (after the formation of the
staple) it is caused to move longitudinally forward, relative to the male former,
by the action of the pin on the male former passing into the upper inclined
portion of the slots in the female die or former, and this is done for the
purpose of carrying the formed staple 7 clear of the male former so as to allow
the driver bar L to drive the staple 7, when placed in proper position for driv-
ing, without coming in contact with the male former.
After the female die or former has been thus moved in advance of the male
former, both are moved horizontally by the lever K³ so as to bring the staples 27
centrally below the driver bar L as shown in Fig. 9.
The cut off and pointed wire is automatically fed between the upper part of
the male former and lower part of the female former as shown in Fig. 10, after
which the female former is caused to descend so as to bend and shape the staple
over the sides of the male former and causing the prongs of said staple to be
held frictionally within the female die or former after the male former has
been withdrawn. Instead of depending on the expanded prongs of the staple
to retain the latter frictionally within the female die or former. I may make use of
one or a pair of friction springs of the kind usually employed in nail driving
devices. L' is the rocking carrier containing the driver bar L; said carrier has
at its lower rear portion, a tee headed projection L2 which, during the rocking
motion of said carrier is guided in a curved slot C5 of corresponding size and
shape in the side of the lower forward end of the arm C as shown in Figs. 2, 4,
9, 10, and 17. An intermittent rocking motion is automatically imparted to
the carrier L by means of a link I pivotally connected to the carrier and actu-
ated preferably by a grooved cam L on the rotary sleeve C' as shown in Figs. 1,
2, 4, 5, 9, 17 and 29, and by such or equivalent mechanism, the said carrier is
rocked from its position shown in full lines in Figs. 9 and 17 to either of its
inclined driving positions shown in full lines in Figs. 2 and 4 and in dotted
lines in Fig. 17 for a purpose as will hereinafter be more fully described.
Within the lower end of the rocking carrier L' is journaled the throat or
receiver L into which the formed staple is forced by the driver bar L at the time
the carrier is held in its central, vertical position.
The carrier L is provided with a longitudinal slot 1 in which the driver
block is longitudinally movable, and to said driver block is secured the driver
bar L as shown in Figs. 2, 4, 9, and 17.
In a bearing C, forming a part of the forward end of the arm C is journaled
a pin or shaft to which is secured the rocking driver yoke, having down-
wardly projecting inclined driver arms L7 L' as shown. In one piece with said
arms is preferably made an upwardly projecting lever L8 to which an inter-
mittent rocking motion is conveyed by means of a preferably grooved cam 18
secured to the rotary sleeve C+ and an intermediate link L' pivotally connected
to the lever L8 as shown.
are longitudinal grooves or ways on the inclined arms L' L' in which
is guided a roll L10 mounted on a pin 710 secured to or made integral with the
driver block as shown in Fig. 18 by which arrangement the driver block
and driver bar are caused to ascend in the carrier during the rocking motion of
the latter from its inclined to its central position, so as to bring the lower end
of the driver bar above the upper end of the staple previously formed, and said
grooves also serve to automatically depress the driver bar when the latter is
moved from its vertical to its opposite inclined position so as to place such
driver bar in position for driving.
Between the inclined rocker arms L7 L' is arranged a downward projection L¹
having a groove or way 12 in which is longitudinally movable the spring pressed
block L3, actuated by a compressible spring 13 which serves to hold the block L13
in its upper position when not depressed, by the pin and roll on the driver block.

page_text: While the driver yoke is held in its mid-way position shown in Figs. 2, 4,
5, 9, 10 and 18, and while the formed staple is being held within the female
die or former K as shown in Figs. 9 and 16, the driver bar L is automatically
depressed so as to push the staple out of the female die or former into the
receiver L, and this is accomplished by means of a rocking lever M pivoted at k
and actuated by a cam m secured to the rotary sleeve C. The forward 'end of
said lever M, during its depression, comes in contact with a pin and roll or
pin L on the driver block, causing the latter and its driver bar to be momen-
tarily depressed for the purpose stated and immediately returned to its highest
position by the influence of the spring
The carrier L is then swung to one of its inclined positions and while held in
such position the driver yoke is rocked sufficiently to cause the driver bar to
descend and drive the staple through the cover and box alternately and clinch
it against the respective clinching surfaces. In hinging boxes by means of
wire staples it is essential that one of such staples should be turned at about a
right angle to the other so as to cause such staples to be properly interlocked
for the formation of the hinge, and for this purpose I employ an automatic
device for turning the staple receiver L³ about a quarter of a revolution at or
about the time the carrier L' moves from its vertical to its opposite rocking
position, and such turning mechanism is preferably constructed as follows. . On
the sides of the staple receiver or throat L³ is a pin or projection N which, as
the carrier and receiver are moved from the central to one of its inclined posi-
tions, is caused to enter a recess in the arm C, by which the said throat or
receiver is caused to rotate about a fourth of a revolution for the purpose stated.
A coiled spring N¹ attached in one end to the said throat or receiver, and to
the carrier L in its opposite end, serves to hold said pin or projection N in
contact with the arm C during the rocking movement of the carrier L', and to
compel said pin to enter said recess during the turning operation, as shown in
Figs. 9, 13, 14, 15 and 30.
It will be noticed by reference to Fig. 22, that the prongs of the staple ,
after the staple is formed by the male and female dies or formers, are left some-
what expanded at their free ends, and by such arrangement, the staple is caused
to be frictionally retained in position, both within the female die as well as within
the throat or receiver before being forced out of such devices by the driver bar,
thus preventing the said staple from dropping out of said die and receiver until
positively actuated by the descent of the driver bar.
The operation of the device is as follows:-
The operator places a box cover D¹ on the horizontal table portion E against
the yielding gage F and places the box 1) upon the yielding brackets GG after
which the operator starts the machine, causing the automatic clamping devices to
force the box in elose contact with the edge of the cover, and to confine the upper
portion of the box and the cover between the vertically movable table and the
underside of the arm C in proper position for receiving the staples as shown in
Figs. 2, 4, 9, 10 and 17.
During a previous partial rotation of the driving shaft, the wire has been fed,
straightened, pointed, cut and formed into a staple, located in position, placed
into the throat or receiver, and the carrier rocked to its position for driving
the staple through the cover and clinching the same; the driver yoke is then
automatically rocked for the purpose of causing the driver bar to descend through
the receiver and drive the staple through the cover and clinch the ends against
the clinching blocks on the horizontal part of the box and cover supporting
table. While the box and cover are still clamped in position, a subsequent
portion of the wire is automatically fed, straightened, cut off and pointed and
a new staple formed, and during such operation, the carrier is automatically
rocked from its inclined driving position to its central vertical position, causing
the lower end of the driver bar to rise above the top of the staple just formed
and placed into position below it, after which the driver bar is caused to descend

page_text: for the purpose of forcing the staple out of the female die and into the receiver,
after which the carrier is automatically rocked to its opposite driving position,
and during such rocking motion, the throat or receiver containing the staple,
is automatically turned about a fourth of a revolution, after which the driver
yoke is rocked so as to cause the driver bar to descend to drive such second
staple through the box and clinch the same against the block in the clamping
lever, and in such a manner as to be interlocked with the previously driven
staple.
The clamping lever is then automatically released and the table lowered to
its lowest position, enabling the operator to remove the now hinged box and
cover and to replace such with a fresh box and cover to be hinged as before.
During the interval of the release of the clamping device, the removal of the
hinged box and cover and the replacing of such with a subsequent box and
cover to be hinged, a new staple has been automatically cut off, pointed, formed
and placed in position for driving and the carrier automatically rocked into
driving position and so on during the operation of the machine.
