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 journaled the rotary driving-shaft B, from which motion is conveyed to the dilferent 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 are longitudinally adjustable the arms C C, 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, G, 7, and 8, D represents the box, and D 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 drivingand clenching of the staple-hinges, as follows; At the front of the frame A is located a vertically-movable angular table E E, composed of a horizontal portion E, upon 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 upward, preferably by means of a continuously-rotating cam-disk e, which actnates a lever c, pivoted at e and having pivotally connected to its forward end a nut 6 containing an adjustable screw 6 the upper end of which bears against a rear projection e on the vertical table portion E, as shown in Figs. 2, 13, and 8. By this arrangemcnt the angular table E E is automatically movable upward, so as to cause the box and cover to be held firmly against the forward lower portion C" of the arms C C, as shown in Figs. 2, 4, and 17, during the driving and clenching operation of'the staples. The table E E is automatically lowered by its own gravity when the cam e ceases to act on the lever 0, 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 staplehinges. The cam 12 is secured to a shaft 6', journalcd in hearings in the frame A, and to it is secured a gear meshing in a pinion 6 secured to the driving-shaft 13, as shown in Figs. 2 and 3.

()n the horizontal table portion E is arranged a yielding gage F, against the rear portion of which is made to bear a preferable leaf-spring F, which is secured to a block F, adjustable on the table portion E, so as to compensate for variations in the width of the covers that are being hinged, shown in Figs. .1, 2, I 4, and 5. A similar adjustable and yielding device is used for the support of the box-body l), and it consists of brackets G G, preferably adjustable to and from each other in a slotted bar G, which is supported 011 a preferable leaf-spring G, that is secured to a block G", adjustable on the table portion E, so as to compensate for variations in the heightof boxes thatare beinghinged,as shown in Figs. 2, 7, and S.

f and f 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 respective cover and box are placed, so as to locate said parts in their proper positions relative to the staple driving and clenching devices.

In bearings in the arms C C is journaled a shaft 0, which is set in rotary motion by means of the pinion e on the driving-shaft l3, meshing in the teeth of an intermediate gear I), secured to a shaft 0, journaled in the upper portion of the frame A. The gear 11 meshes in a gear C secured to the shaft 0, andin this manner a rotary motion is imparted to the said shaft C. On said shaft 1 are splined a pair of longitudinally-adjustable sleeves 0', (one for each of the staple making and driving devices,) and to said sleeves are secured the various cams for op erating the wire feeding and straightening, cutting-off, and pointing device, the stapleforming 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 II, that is pivoted at its rear end to a rocking lever II, which latter is pivoted at its lower end on an adjustable fulcrum ll, secured to the arm C, as shown in Figs. 1, 5, and 25. The forward end of the link II is pivoted to the upper end of the clamping-lever H which is pivoted to the forward end of a longitudinally-adjustable bar II, that is adjustably secured tot-he arm 0 at h for the purpose of compensating for variations in the thickness of the stock of which the boxes are made. This bar II" is supported intermediate its ends on the pin II, disposed at right angles thereto, as seen in Fig. 5. \Vithin the inner face of the clamping-lever H is secured a preferably steel-hardened clenching-block I13, against which the pointed ends of the staple driven through the box-body are clenched during the staple-driving operation.

f f are clenching-blocks arranged in a groove f in the horizontal table portion E, against which the pointed ends of the staples driven through the cover are clenched during the driving operation. The clenching-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.

h is a spring which actuates the lever H", so as to automatically release the clampinglever H as soon as the cam I-l ceases to act on said lever H, 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 as follows: Each of the staple forming and driving devices receives its wire 2' from a reel I, from which the wire is intermittently carried by the feeddevice partially around a loosely-rotating grooved wheel I, and from the latter between a pair of straightening-rollers I 1 one 'or both of which may be adjustable, although in practice it may only 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 I I pivoted at i 11 to a slide 1 which is set in a reciprocating motion, preferably by means of a rod 1 pivotally connected to said slide and actuated by a track-cam 1 secured to the rotary sleeve as shown in Figs. 1, 2, 4., and 27. The levers I I are caused to impinge on opposite sides of the Wire by the influence of springs 2' when the slide 1 is moved in the direction of the arrow shown in Figs. 2 and 4. Vhen the slide 1 is movedin 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 1 and a spring-pressed brake 1 as shown in Figs. 2 and 4:. The wire is cutoff and pointed as the slide 1 approaches the forward end of its stroke by the levers I 1 coming in contact with stops d v/' adj ustably secured to the arm 0, by which the said levers are caused to rock backward 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 the length of staple required. By adjusting the position of the stops 1' i 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 1 1 which during the return motion of the slide 1 come in contact with the upper ends of the levers I 1 causing them to be released from gripping the wire and held so until the said levers are released from contact with said blocks 1 1 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 0 are arranged a female die or former K and a maleformerK. Thefemaledieorformerhasa Vertical perforation k for receiving the driverbar, and at two opposite sides of such perforation are made longitudinal recesses 70' for receiving the sides of the staple during the forming operation, as shown in Figs. 5, 9, 10, 11, 12, and 16.

K" is a vertically-movable plunger guided in ways on the arm 0, and to it is imparted a vertical reciprocating motion by means of a lever K pivoted at k to the arm 0 and operated in one direction to force the plunger down by means of a cam K secured to the rotary shaftsleeve O and in the opposite direction by the influen cc of a spring 70 as shown in Figs. 2, 4, 5, and 28. The forward end of the lever K is pivotally connected to the upper end of the plunger K, as shown. The lower end of said plunger K is connected to the female die or former K in such a manner as to permit the female die K to belaterally m ovable 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 K pivoted at 7& to the frame 0 and operated in one direction by a cam K secured to the sleeve 0 and in the opposite direction preferably by the influence of a suitable spring.

To the male former K is secured a pin or projection 70, adapted to be received in slots 70 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 2' by bending it over the male former without causing such female die to move horizontally, and during such stapleforming operation the projection 76* on the male former is received in the vertical lower portions of the slots 1: k 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 7& on the male former passing into the upper inclined portion of the slots 70 in the female die or former, and this is done for the purpose of carrying the formed staple 1' clear of the male former, so as to allow the driverbar L to drive the staple '6 when placed in proper position for driving 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 K so as to bring the staple t' 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 frictionsprings of the kind usually employed in naildriving devices.

L is the rocking carrier, containing the driver-bar L. Said carrier has at its lower rear portion a T- headed projection L, which during the rocking motion ofsaid carrier is guided in a curved slot C of corresponding size and shape in the sides of the lower forward end of the arm 0, as shown in Figs. 2,-1, 9, 10, and 17. An intermittent rocking motion is automatically imparted to the carrier L" by means of a link L, pivotally connected to the carrier and actuated, preferably, by a grooved cam L on the rotary sleeve (1*, as shown in Figs. 1, 2, 4, 5, 9, l7, and 20, and by such or equivalent mechanism the said carrier is rocked from its position shown in full lines in Figs. 5) 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.

\Vithin the lower end of the rocking carrier L is journaled the throat or receiver If, into which the formed staple is forced by the driver-bar L atthe time the carrier is held in its central vertical position. The carrier L is provided with alongitudinal slot Z, in which the driver-block l is longitudinally movable, and to said driver-block is secured the d riverbar L, as shown in Figs. 2, i, 9, and 17.

In a bearing 0 forming a part of the forward end of the arm 0, is journaled a pin or shaft l, to which is secured the rocking driveryoke, having downwardly-projecting inclined driver-arms L L as shown. I11 one piece with said arms is preferably made an upwardly-projecting lever L to which an intermittent rocking motion is conveyed by means of a preferably-grooved cam Z secured to the rotary sleeve C and an intermediate link L", pivotally connected to the lever L as shown.

I Z are longitudinal grooves or ways on the inclined arms L L in which is guided a roll L mounted 011 a pin Z secured to or made integral with the driver-block Z, as shown in Fig. 18, by which arrangement the driverblock 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 d river-bar when the lat ter is moved from its vertical to its opposite inclined position, so as place such driver-bar in position for driving.

Between the inclined rocker-arms L L is arranged a downward projection L having a groove or way W, in which is longitudinally movable the spring-pressed block L actuated by a compressible spring P", which serves to hold the block L in its upper position when notdepressed by the pin and roll on the driven block.

lVhile the driveryoke is held in its midway position (shown in Figs. 2, 4, 5, 9, 10, and 1S) 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 said female die or former into the receiver L and this is accomplished by means of a rocking lever M, pivoted at [t 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 drivenbar to be momentarily 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 sufliciently to cause the driver-bar to descend and drive the staple through the cover and box alternately and clench itagainst the respective clenching-surfaces.

In hinging boxes by means of wire staples it is essential that one of such stables 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 L 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 side of the staple receiver or throat L is a pin or projection N, which as the carrier and receiver are moved from the central to one of its inclined positions is caused to enter a recess a in the arm 0, by which the said throat or receiver is caused to rotate about a fourth of a revolution for the purpose stated. A coiled spring N, attached in one end to the said throat or receiver and to the carrier L in its opposite end, serves to 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 2' after the staple is formed by the male and female dies or formers are left somewhat 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 driverbar, 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 D on the horizontal table portion E against the yielding-gage F and places the box D upon the yielding brackets G G, after which the operator starts the machine, causing the automatic clamping devices to force the box in close 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 under side of the arm 0 in proper position for receiving the staples, as shown in Figs. 2, 4, 9, l0, and 17. During a previous partial rotation of the driving-shaft the wire has been fed, straightened, pointed, out, 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 clenching the same. The driver-yoke is then automatically rocked for the purpose of causing the driverbar to descend through the receiver and drive the staple through the cover and clench the ends against the clenching-blocks .on the horizontal part of the box and cover supporting table. l/Vhile the box and cover are still clamped in position, a subsequent portion of the wire is automatically fed, straightened, out 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 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 clench 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.
