lMPROVEM ENT m APER-Box MACHINES.

Specification forming part of Letters Patent No. 132,078, dated October 8, 1872; reissue No. 6,745, dated November 16, 1675: reissue N0. 7,40! dated November 2c, 1876; application filed September 26, 1876.

To all. whom it mag concern:

lie it known that we, HENRY R. HEYL and Aocns'r Bnrnnrnn, both of the city and county of Philadelphia, in the State of Pennsylvania, have invented a Machine for. Making Boxes of Paper, Pasteboard. and other Material, of which the followingis a specification I The machine is intended, primarily, for making boxes of paper or pasteboard without cement, the fastening being elfected by wire staples, which are produced and applied by the nmchine which forms the boxes. It will obviously, however, fasten material together by wire staples driven through and clinched upon the under side of the same, whether such material is in the form of a box or not.

In tormingboxes the box-blanks are placed in a receptacle provided with a sliding platiorm, which is drawn up by a weight and cord applied to a t'useepulley, adapted to graduate the power of the weight to correspond with the number, and consequent weight, of the blanks remaining in the receptacle. The weight-pulley is detainedby a ratchet, which prevents the drawing up of the sliding platform, excepting when the said ratchet is retracted. The blanks are taken, one by one. from'the top of the pile by a. pneumatic or suction feeder provided with automatic valves, to adapt it to seize and drop the blanks at the proper moments. The said feeder, in its descent, retracts the detent-ratchet, and receives a slight upward pressure from the pile of blanks. As the feeder rises again with one blank the detent, being released, catches the weight-pulley,so that,'whether the quantity of blanks be greater or less, the top ot' the pile always rests at one level to receive the feeder. .The blank, being deposited on a table by the feeder, is carried forward by a follower to a position over the mold, into, which it is forced by a plunger, the bottom flaps b eingfirst bent up, and the end flaps next tolded over them as the plunger descends. plunger is also the clincher-stock, and constitutes the worksupport during the operations oi" inserting and clinching the staples. The'wirc to form staples is, in continuous lengths, contained on reels equal in number This to the staples used in each box. The wires being fed forward by rollers at each stroke of the machine, the necessary length to form a staple is cut from each wire by. a cuttingpunch, which is bifurcated, so as to form a bending-fork, working over a transverse forming-mandrel, around which the wire is bent into the form ot'a staple by the pressure of the said bending-fork. The bendingfork is formed with internal longitudinal grooves, which reeeive'the staple as it is formed, and hold it securely while it is carried by the motion of" the bending-fork to the proper position to be driven. The forming-mandrel then recedes, and the staple is driven through thelapped sides of the box by a hammer or driving-rod moved longitudinally within thc'bending-t'ork.

Cavities in the plunger or clincher stock receive inwardly-projeeting ends of the staple,

which ends are then bent in opposite 'direc tions, either toward or-away from each other, by clinchers, while the head of the staple is still held by the hammer or driving-rod. The plunger or clincher stock is then withdrawn, and its descent, with a new box, discharges thatwhich was previously formed.

The various parts are made changeable or adj ustable,-to adapt them for the manufacture of boxes of various sizes, forms, or thickness of matcrial. p

The movement-ofthese sliding plates isgproduced tby levers 3 1 and 33,-the formerbeing fnlcrunied at its center 32, andthe lat-' .ter at one end, 34, andthe twdbeing. connected hy a rod. 35. The forwardendot' the lever 31 is jointed to? a verticalxlevergiifi, which is fulcrumed to-a. stationary standard onithe 1 frame, and is operatedbyjastud, 37, on the cross-head 19-working in'avsloti 'n said lever 36.

Upon the descent of the cross-head 19 it causes the plunger or clincher stock 43 to carry the blank down into the mold 42, in which the box is formed. This mold consists of two bottomflap folders and two end-flap folders, the latter having two inclinedflanges, each arranged .stock. Then, as the plunger or clincher stock descends still farther, the box-blank is forced between the side folders 56 56, which causes the sides of the box-blank 4 4 to also fold up against the plunger or clincher stock. The next operation consists of foldiu g the end flaps 53 .53 around the plunger or clincher stock, 52 52, which latter are still held against the plunger or clincher stock by the long points of the folders 54 54, until. the end'flaps53 53 are folded around sufliciently to retain the'bottom flaps 52 52 in place. This folding of the end flaps 53 53 is done by the inclined flanges 97 97, projecting from the side folders 56 56 at each corner ofthe mold. These fianges are so narrow that they do not extend across or overlap each other, but project only a short distance around theends of the box, leaving space enough between each opposite pair'to admit the passage of the mechanism thatins'erts the wirenstaples through the box sides or the flapsforming the same. The flanges gradually assume a right angle with theside folders as they approach the bottom, so that, when the box is clear down into the mold, the flaps 53 53, which form the ends of the box, are bent around in position to receive the wire staples. Each one of the pair of opposite flanges is so inclined in relation to its fellow that-the side flaps are edges areintended to meet flush, or one flange should be inclined a little in advance of the other if the side flaps are intended to overlap each other, as is the case in the form of box here represented. I

This mechanism consists of a horizon tal' yoke-lever, 60, fulcrumed at its center,

proper length of wire same time, when their tion to the clinching mechanism.

The plunger orclincher stock has the shaft 63. As soon as 61, and inclosing' a wrist-pin, 62, on the vertical shaft 63, driven by bevel-piniohs 64. (See Fig. 2.) The yoke of theflever 60, in which the wrist-pin 62 works, is formed with two shoulders, 65 66, with which the said wristpin engages alternately to move the lever in opposite directions. l\'o eli'ect is produced on the lever while the pin passes over the curves between the shoulders. A connecting-mil, 67, at the free end of the lever 60, is jointed to an arm, 68, carrying a pawl, 69, which engages with a ratchet-wheel, 70, on one of the rollershafts, the two rollers of each pair being geared to turn together.

It will thus appear that each forward move- .mcut of the lever imparts a slight rotary movement to the feed-rollers, and the parts are so constructed and proportioned that each movement will feed forward a length of wire sufiicient to form a staple.

()ne pair of feed-rollers, with their operating mechanism, may, as represented, feed all the wires used on one side of the machine.

The operation of cutting, forming, driving, and clinching will be described with reference to a single staple, it being understood that this operation may be performed simultaneously in two, four, six, pr even more places, according to the dimensions of the box which the machine is atthe time employed to make. The drawing shows mechanism tor applying four staples-two on each side. The mechanism for.cutting, forming, and driving the staples is shown in Figs. 8, 9, and 10. A is severed and bent around a square-forming mandrel, 71, by a cutting-punch or. bending-fork, 72, formed to pass transversely over the forming-mandrel 71, and havingjn' its interior longitudinal grooves 73, Figs. 9 and 10, which receive the wire as it is bent around the formingmandrel to form a staple, and hold the said staple in proper position for driving. The reciprocating movement of the cutting-punch or bending-fork 72 is imparted by 'a cam, 7*, upon. the

shaft 63, audits operation is such that it bears upon and compresses the material while the staple itcontains is being driven and clinched, and is then retracted. It thus directs the staple-legs in lines parallel with its internal grooves, and guides them so tha.' they will protrude through the material in proper rela' Within the bending-fork or cutting-punch 72 is a reciprocating hammer or driving-rod, 75, held back by a pin, 76, which engages a pin, 77, projecting from the hammer or driving-rod 75, and which, when-released by the retraction of the pin 76, is driven forward by a spring, 7 8. The forming-mandrel 71 and pin 76 are both attached to a crank-lever, 79, .fulcrumed at 80, and moved back and forth by a cam, 81, on the motion of this lever withdraws the forming-mandrel 71 from before the staple, the latter bei ng still held in position by the grooves 73, the pin 76 releases the pin 77, permitting the spring 70 to drive slider 88.; These lugs sion on the staple,

curely held and guided by the longitudinal grooves in the bending-fork or cuttin'g punch 72., so as to prevent their bendingwhile the staple is being driven through the paper, and to present them in the proper relative positiouto the clinching mechanism for its operation uponthenr. The ends of the staples are received in suitable cavities in the edges of the plunger or clinch'er stock 43. The mechanism for clinchingor bending over the ends of the staplesis represented in Figs. 5, 6,.and 7, and consistsof plates carrying legs orv jaws 89 90 91-- '92, which plates slide between fixed. plates" 101,

which constitute theplu-nger or clincher stock. Figs. 5 and 6 show the positions of the partswhen the staples are driven, and before they areclinched. Fig.7 shows the-position when they are clinched. 0n the' head of the vertical shaft 63 is a disk or wheel, 95, from the upper surface of which project 7 two pins, 99 and 100, which operate a rockshai't,'82, mounted horizontally in bearings under the cross-head. This rock-shaft has 'a pair of tnppets, 83 and 84, on which the pins 99 and 100 not successively. Upon the shaft Sit-are rigid arms 85 87, projectingin oppositedirections,

sliders 86 and tutet'he. plunger or clincher stock 89 and 91rep'resenthorizontal. lugsor jaws on the or jaws are arranged alternately, as represented, so that themetion of the-shaft82 in one direction, by de pressing the slider 86 and elevating the slider 58, moves the two lugs or jaws 89 and .90 toward each other, and the two lugs .or jaws 91 and 92 toward each other. e I

I As soon as the downward stroke of the cross-head 19 has formed the box within the mold, and the staple has been driven, in the manner explained, with its legs resting between the lugs 9Land 92, the rotation of the shaft 63throws the pin 99 against the tappet 83, rocking the shaft 82 in one direction, bringjug together the pair of lugs "91 92, so as to bend the two legs of the staple *tpward. each other, flat againstthe surface of: the material,

. and efl'ectually. secure them without the neces'sity, of subsequent hammering. This positioi ot' the'parts ijs. shown fin Fig. 7-. The

took again descends The legs of the staples are se-' by the main frame in such and respectively connected to 88, which two sliders constiwitha new blank, previously-.lln-ished box isexpelledthrough the bottom of the mold.

A modification inthe construction of the plunger or clincher stock is illustrated in Fig. '2.-- -In this case the body of the plunger or clincher stock ismade in one piece, with a single slider working in it. The motion .of the shaft in one direction throws down this slider, .to .benddo'whthe upper part of each staple,

and the reverse Imotiou opens I the cavity, as before.

Thisopeni'ng' of the cavity is per. formed directly before the action ofgthefliammer or driving 75, and is followed by the clinching action just described. The. elevation ot the plunger or clincher stock itself then bends )up work is connected at one end. only with its support, and the staple forming and inserting mechanisms are carried in a head supported relation to the plunger 01' clincher stock that thereis provided a. free passage for thematerial operated .upon in ,a

the clincher-stock, and between 'it audthe stapling mechanism. This'construction facilitat'es the presentation and removalot the work, and: it also admits of-the" introduction of the clinching mechanism-into abox to- -clinch a staple onthe'inside of such hollow articles. he heads which carry the-staple 'forming and inserting-mechanisms are supported inways 94 in the faces oi" the standards .2 of-thetrame-work. In these 'ways the said heads are adjustable,.' by means of setscrews95, to and'from thep'lunger or clincher stock which supports thework, and thus adjust the staple forming and inserting-mechanv isms in. such relatiouto the staple-clinching mechanisms. as to adapt the" machine for operation upon diiferentfthickuesses of work.-
