STAPLE-BINDING DELIVERY MECHANISM FOR PRlNTlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 510,845, dated December 12, 1893. Application filed August 19, 1893. Serial NO. 433570. (No model.)

To all whom it mag concern.-

Be it known that I, LUTHER O. CROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York,

have invented certain new and useful Improvements in StapleBinding Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a to part of the same.

This invention relates to that class of stapling devices more .particularly adapted for attaching together or binding the plies of moving material such as the product delivered from a printing mechanism; and more particularly to that class of stapling mechanisms which are of the rotative type or such as have staple inserting means that move rotatively to co-operate with a clinching device in the operation of inserting the staple and clinching its legs, whereby the rapid onward movement of the material to be stapled may be maintained and a rapid production of the finished product take place, as is more particularly set forth in my application, Serial No. 464,007, filed February 28, 1893.

The invention as embodied herein consists of a rotative mechanism in which the staple holder or presenting tool is made to oscillate and thus moveto and from the staple setting point, and the invention embraces the novel constructions hereinafter fully described, shown and claimed.

The drawings illustrate a practical struct- 3 5 ural embodiment of the invention, in which- Figure 1 isaside elevation of so much of a delivery apparatus of a printing machine as is necessary to illustrate the combination therewith of this improved stapling mechan- 4o ism. Fig.2 is a side elevation of the stapling mechanism opposite to that shown in Fig. 1. Fig. 3 is a plan view thereof, showing more particularly the wire feeding mechanism. Fig. 4 is a longitudinal sectional elevation 5 through the upper member of the compound tool, on the line a of Fig. 6, and shows the staple bender in plan and partly in section. Fig. 5 is a-similar view on the line 5 of Fig. 6, and shows the staple driver in plan. Fig.

6 is alongitudinal sectional central elevation the rollers 75, 76.

of the compound tool when the same is in the raised position shown in Fig. 1. Fig. 7 is a front end elevation ofthe staple holder or presenting tool. Fig. 8 is a plan view of the wire cutter. Fig. 9 is a perspective view of one of the cams. Figs.10 and 11 are front and side elevations of the staple clinching device.

Although no machine for the production of the material to be stapled is shown herein, it is to be understood that the rollers 75, 76 illustrate a pair of rollers through which plicated sheets or webs are carried outward for delivery, as from a printing machine. The plicated sheets may be led for final disposition, into a folding machine, whereby they will be doubled one or more times and laid fiat in a pile. WVhen, however, the product passing the rollers is in the web form the plicated web or webs will be severed transversely by a cutting mechanism and the resulting sheets be finally delivered as by folding. In this improved means for delivering such products the same are to be united to gether in, onor along their ultimate binding line by small wire staples passed through the plies and clinched in place, the stapling apparatus for applying these staples being preferably located between said delivery rollers 75, 76 and the final delivery apparatus, as the cylinders A, B, which latter may be supplied with cutting and folding mechanisms, one or both, as is common in the printing art and as is fully set forth in my said application, Serial No. 464,007.

As the preferable object of the stapling mechanism is to unite together plicated material received from a printing machine it will be understood that the printing machine may be of any construction that will produce sheets or webs plicated as they emerge from Thus two or more printing machines provided with means for associating sheets or webs will produce a compound product as one consisting of two or more sheets or webs, while a printing machine having two or more sets of complete printing mechanisms operating upon a single width of web or sheet and provided with a slitter or slitters and a longitudinal folder or folders,

will produce a plicated product; hence, it will be understood that this stapling mechanism is adapted as a part of the delivery appara tus of any printing mechanism that delivers sheets or webs plicated by associating rollers, bars or folders, and whether or not, when webs are printed upon, the same are severed into sheets before or after the same reaches the delivery rollers 75, 76.

In the structure of stapling apparatus shown, the parts are arranged to set the staples at right angles to the travel of the material to be stapled. I11 this arrangement there must of course be as many of these stapling apparatuses as it is desired there shall be staples in the material. Ordinarily two staples will be sufficient, but three or more maybe setlin an aligned row widthwise of the material or transversely to its run through the apparatus, but it may be here remarked, that by slight modification, mechanisms may be arranged so that the staples Willi) be set in the direction of the run of the we In this stapling apparatus, as illustrated, the staple is formed, carried to and presented at the staple setting point, by a staple inserting means, the holder or presenting tool of which oscillates from the point of reception of the staple to the setting point thereof, where it is inserted and clinched in the material by means of a driver or inserting tool, in this instance reciprocating in said holder or presenting tool, and a stationary co-operating clinching die. The oscillation of the holder or presenting tool is preferably so timed that as it approaches, reaches and passes the staple setting point, its direction of and speed of travel is that of the moving material through which the staple is to be inserted, and in which it is to be clinched or set. In the return movement of its oscillation this holder or presenting tool returns to the wire feeding mechanism, cuts off a staple length of wire, and said wire length is formed into a staple and delivered Within the presenting tool or holder, ready for a repetition of the downward movement or carrying or presenting operation.

The wire feeding, staple forming, holding, presenting or carrying and inserting tools or devices are all supported upon a stationary plate bracket 100 which projects from an arm 101 that is secured to the frame of the ma chine and is suitably located beneath the delivery rolls 75, 76 through which the plicated material to be stapled is fed onward for delivery.

The movements of the stapling mechaih isms are imparted by a connecting rod 51, that is reciprocated by timely movements imparted by a cam 52 which is for convenience shown as fixed upon theshaft of the cylinder A, which is one of a pair A, B that supports cutting mechanisms, by which the stapled material is severed into sheet lengths, and which may also carry folding devices for folding the staple sheet if desired. This cam 52 is suitably shaped to give the requisite movement to the staple holder or presenting tool and the staple driver inserting tool or device reciprocating therein, so that the speed of movement of the holder or presenting tool at the time of the setting of the staple shall c oincide with the movement of the material in which the staple is to be set.

The stationary plate bracket 100 1s provided with a wire feeding slot 9 through which the wire 4 is fed by means of a reciprocating clamping slide 20, that is guided in an arm 21. The wire received from a wheel is passed through said slot and nipped in the feed ng direction by a pawl 22 carried by the slide and held against any return movement by a pair of spring seated dogs 23, 2 1, the necessary reciprocatory motion being given to the slide 20 by means of a bell-crank 25, and a reciprocating rod 26, abowl attached to wh ch runs in the slot of a vibrating cam 27, which cam swings on the shaft 28 over which shaft the rod 26 slides by means of its bifurcated end.

The holder or presenting tool and the forming tools have their center of motion upon the shaft 28 so as to have a rotative movement, namely, an oscillation. The carrier, 29, which contains the forming anvil 31 and provides cooperating bending arms 2, 3, is SIIOWH'IIJ section in Figs. 3,4,5 and 6, and ahead which is provided with a wire slot 10 for the recep tion of the staple length of wire that is fed to it through the directing slot 9 in the plate feed 100. This carrier 29 has a downward movement determined by i a rest block 30 which supports said head with its wire slot 10 aligned with the slot 9, so that the staple length of wire may be fed into said head to a distance suitable for the formation of a staple, and said carrier 29 is capable of rising above said block 30 a suitable distance in aid of the operation of forming the staple. The head of this carrier 29 is made hollow to a size adapted to receive, support and guide a reciprocating forming anvil 31, that carries a rack 32 through which it is moved to and fro by means of a rocking segment 33 carried by a lever 34 that is hung in bearing arms 5, 6 fast to the anvil 31, the slotted upper end of which lever 34 is controlled by a pivot 35 fixed to the plate 100.

The staple holder or presenting tool is shown in Figs. 3, 5 and 6 in section. It is hung to oscillate upon the shaft 28 and has the cam 27 attached to it. This presenting tool 39 is capable of moving downward to or slightly beyond the dotted position of it shown in Fig. 1, and upward to a position slightly above that shown in full lines in the same figure. This presenting tool 39 is recessed longitudinally to form two holding arms 7, 8, the inner sides of which are provided with longitudinal slots approximately of the size of the wire from which the staple is formed, into which the staple legsare carried or drawn during the formation of the staple, as will presently be explained. This holder or presenting tool 39 is also provided in its inner sides with longitudinal guide slots in which reciprocates the driver or inserting tool 41. This driver 41 is provided between the base of the presenting tool 39 and its own rear end with a spring42 preferably supported on a rod, as shown, and on one side there projects from the driver 41 a stud 43 that engages a fixed cam plate 44 as the stapling inserting means moves upward, and a trigger cam 45 as the said staple inserting means moves downward. This trigger cam'45 is pivoted so as to slightly swing,it being'held in its forward position against a stop 47 by means of an arm 46 attached to its shaft and borne upon by a spring 48. The oscillating movements are imparted by means of the cam 52 through the connecting rod 51, which vibrates a two armed swinging lever, to one arm 53 of which the connecting rod is attached, and the other arm 54 of which is connected by a link 55 with a rock arm 56 attached to the rear end of the staple holder or presenting tool. When the said holder or presenting tool 39 which carries or transports the staple from the forming point presents it to the inserting point of the material and moves with it down to the setting point, afterward makes its upward or return movement, it will not only come in contact with the carrier 29, but lift the same from ofi the rest block to a distance sufiicient to enable the cutter 36, which is fixed to the holder or presenting tool to sever a staple length of wire by the movement of said cutter past the wire feeding slot 9, and immediately following the cutting of the wire as the upward concerted movement of the carrier 29, and the holder or presenting tool 39 is continued, the slotted arm 34 will move over the 'pin or stud which will act to rock the segment 33 rearward, and through the rack 32 impart a like movement to the forming anvil 31 which will in such rearward movement draw the wire length inward thus causing the bending arms 2, 3 to bend the ends of the wire length at right angles to its central body portion, thereby converting the same into a staple, the legs of which are drawn within the grooves in the inner faces of the arms of the holder or presenting tool 39 while the crown or head of the staple rests against the end of the driver or inserting tool 41, as seen in Figs. 5 and 6, which driver 41 is then held in its rearward position by means of its arm 42 bearing in senting tool 39, and, as that member further descends, the staple will be transported or carried by it into position relative to the material foritsinsertiontherein. Now while this holder or presenting tool 39 is makingits downward movement its stud 43 will pass onto the rear face of the trigger cam 45, the curvature of which will slightly but still further compress the spring 42, and, when the forward end of the holder or presenting tool 39 has reached the setting point for the staple, the'stud 43 of the setting tool the arm 43 of the driver will pass off from the lower end of the trigger cam 45, thus releasing the spring 42, which will suddenly and with great power quickly expand to thrust said driver or inserting tool forward until it is arrested by the rear ends of the arms 7, 8, thus carrying before it the staple, causing the same to be entered through the material and the legs thereof to be clinched by a suitable clinching device as a fixed block 37 having a shallow recess or die with curved ends therein. This inserting and clinching operation will, therefore, be performed while the staple holder orpresenting tool is moving in the same direction and with substantially the same surface speed at which the material is traveling, and hence be performed without injury to the moving material, and as soon as the staple is inserted and hasits legs clinched down, it will be relieved from any hold by the presenting and inserting tools .so that the same may be retracted or moved upwardly while the material carrying the staple moves onward. During this downward movement of the holder or presenting tool 39, and it may be during its partial return, a wire length is again fed forward into the head of the carrier 29, and when the holder or presenting tool 39 moves upward, its stud 43 will pass in front of the trigger cam and making contact with the cam plate 44 will be gradually moved rearward, thereby compressing the spring 42, and when the holder or presenting tool 39 comes in contact with the carrier 29 it lifts the same, causes the cutter 36 to severawire length, the segment 33 torock and draw the forming anvil rearward, thus bending such wire length into staple form, and depositing the same in the grooves in the arms of the holder or presenting tool 39 with its crown or head resting in front of the driver or inserting tool 41.

The staple inserting means consist generally of astaple holder or presenting tool which holds or presents the made staple so that its legs shall properly enter the material, and a tool or driver which acts to compel theentrance of the staple into the material. The holder or presenting tool may also act as a tool or driver for inserting the staple into the material, but it is preferable in this form of the mechanism that a separate and movable tool or driver shall be present.

The clinching mechanism may be of any suitable form but as herein shown, and asjs preferred, since the operation of the setting mechanism is a very rapid one, said setting tool may be a simple block or clinching die 37, as shown in Figs. 1, 10 and 11, the face of which is provided with a transverse recess, the ends of which are slightly curved to cause the staple legs to bend inward. or toward each.

other, and which recess is continued downward in the block so that the clinched staple legs may pass out of or oil from the same Without obstruction, and it is preferable to continue the curvature or inclination of the ends of this recess throughout the depth of the block, so that the actual clinching may be prolonged slightly to insure a perfect operation.

The cylinders A, B, are shown by peripheral lines only, since they may be provided with simply cutting mechanisms, or cutting and folding mechanisms, asis fully described in my said application, Serial No. 464,007, and in my applications, Serial Nos. 483,191 and 483,192, filed August 15, 1893.
