PIN-TICKET IVIAGHINE.

Application filed December 9, 1913.

To all whom it may concern.

Be it known that I, HERMAN Hnrnn, a subject of the Czar of Russia, residing at Brooklyn, county of Kings, State of New York, have invented an Improvement in Pin-Ticket Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to machines for making pin tickets for attaching to merchandise of various kinds and more particularly to an automatic device for n1aki11g wire pins or staples having doubled wire prongs for such tickets. The invention may be embodied in a machine of the general type of that shown in the patent to Kimball No. $57,782 granted August 18, 1891.

The invention has for an object to pro vide mechanism for makin staples having prongs of doubled wire folc ed at the points.

.Another object is to provide an automatic mechanism for making pin tickets in which the wire will be doubled at the points of the pin so that the pin when in use will not have sharp or jagged points to catch the threads of merchandise or injure the lingers.

in accordance with my present invention 1 provide a mechanism for making staples having doubled wire prongs and attaching these staples to blanks of cardboard or other material. The staple-forming mechai'lism includes means for bending the wire to a U-shape and means for folding or doubling the ends of the wire whereby the finished staple will present doubled wire prongs. In the embodiment illustrated the means for bending the wire operates first and the doubling means afterward, the order of operation however is not material.

The nature and objects of the invention will be more fully understood from the following specification and accompanying drawings in which the novel features will be particularly described and then pointed out in the appended claims.

Referring to the drawings in which I have illustrated a selected embodiment of my invention, V

Fig. 11 is a similar view showing the staple applied to the card, the card being shown in dotted lines.

Referring to the drawings in detail, a

supporting frame is indicated at 1. On this frame is mounted a bed, 2, which supports the staple-forming and driving mechanism and the wire feeding mechanism, a stand, 3, secured to the bed providing convenient means for the attachment of certain parts. Power is supplied by front and rear cam shafts 4 and 5, which are geared together to rotate in unison as by a shaft 6, and miter gears connecting each cam shaft thereto. These shafts may be driven from any suitable source of power.

Any convenient form of Wire-feeding mechanism may be employed, it being essential only that predetermined lengths of wire should be delivered to the staple-forming mechanism. In the form illustrated, a strand of wire 7 is intermittently fed through the hard steel die 8 secured in a bracket 9 fast to the stand, by a feeding mechanism comprising a slide 10, with a lever 11 pivoted thereon and operated by a link 12, controlled by a lever 13 and a cam 14 on the forward cam shaft. The rearward movement of the lever relative to the slide is limited by an adjustable stop 15 in the form of a wedge positioned against a stop pin 16 and held in adjusted position by a set screw. A jaw 17 is carried by the lever and is adapted to clamp the wire a ainst a corresponding jaw on the slide.

he movement of the slide depends upon the amount of free movement of the lever relative to the slide and may therefore be adjusted by means of the wedge 15, thus determining the length of wire to be fed. Upon each rotation of the cam the slide is moved forward and back, the wire being automatically gripped between the jaws on the forward movement of the slide and released upon the return movement thus providing an adjustable intermittent feed. A. knife 18 is slidingly mounted adjacent the die and serves to cut the wire after each feeding movement. The wire is fed through the die on a line above the plane of the bed and upon being cut, is dropped into position to be operated upon.

lVire bending devices receive the lengths of wire and bend them to form staples having double prongs, these devices comprising in the embodiment illustrated a die or former movable to and from operative position, a plunger and folder movable relative to the die and hammers to compress the prongs. It will be obvious, however, that the necessary relative movements of the parts may be obtained in other ways than that illustrated. The former is indicated at 19 secured to the lower end of a slide 20 and provided with two parallel flanges 21 and 22 around which the wire is bent to staple form. The slide 20 is vertically movable in a way 23 in the back of the face plate 24. The operation of the former and of the knife are such that both may be conveniently controlled by the same cam. Accordingly the slide is connected at its upper end to a bolt 25 to which bolt the knife 18 is also connected as by a clamp. An operating lever 26 pivoted at 27 and controlled by the cam 28 on the rear cam shaft engages this bolt and thereby operates the knife and former. A plunger 29 having a wire receiving groove 30 around its edge is adapted to engage the severed wire at its middle point and draw it through the former between the flanges 21 and 22 thus bending the wire to an approximate U-shaped form as shown in F 6, the end of the wire being brought into engagement with the grooved fingers 31 and 32 of a folder 33. The plunger 29 preferably rather closely between the flanges of the former. The folder is adapted to move forwardly folding the ends of the wire against the outer side of the flanges 21 and 22- thus giving the wire the form shown in Fig. The plunger 29 is slidably mounted in the folder 33 which in turn is slidably mounted in the folder guide 34 secured to the bed. The plunger 29 is operated by a lev-r 35 pivoted at 36 and controlled by the cam 37 on the forward cam shaft. A link 38 connectsthe lower end of the lever to the plunger. The folder 33 is operated. by a lever 39 pivoted at 4:0 and controlled by a cam 41 on the forward cam shaft. After the ends of the wire have been folded about the flanges of the former the folder is withdrawn and the former raised by their respective cams. I prefer to provide mechanism to compress the folded ends of the prongs in order thatthe points may be as small as possible and in order that the parts of each prong may lie close together. In the embodiment illustrated the prongs are compressed against the plunger 29 after the former and folder are withdrawn by hammers 42 and 43 the groove 30 in the plunger being of a depth equal to twice the thickness of the wire to receive the prongs. These hammers are pivoted to the face plate 2st by the screw bolt a l and are operated by links 4-5 and connected to the upper ends of the hammers and to a link d7 operated by a lever 48 pivoted at 49 and controlled by the cam 50 on the rear cam shaft. The face plate 24 to which the hammers are pivoted, is secured in place on a plate 51 fast on the stand 3, by six screws Retaining mechanism may be provided to temporarily hold the staple on the plunger dur ing the withdrawal of the former and folder and until the hammers have engaged the staple. Such mechanism may conveniently be carried by the hammers and in the embodiment illustrated consists of arms 53 and pivoted to the hammers by screw bolts and 56 respectively and pressed inwardly by springs 57 and 58 secured to the hammers. The screw bolts and 56 preferably extend through holes in the hammers and are screwed into tapped holes in the arms so as to be readily accessible from the front of the machine. The relative movement of each arm is limited by a pin 59 secured in the hammer and projecting into a hole 60 in the arm, the difference between the sizes of the pin and hole being such as to permit the desired movement of the arm relative to the hammer. lVhen the arms are in their outermost position relative to the hammers the faces of the arms are even with the faces of the hammers. These arms are pressed inwardly by their springs and are adapted to i engage the pin before the folder is entirely withdrawn so as to hold the pin in position on the plunger as the folder and former are retracted, the respective cams being so timed that the hammers will be moved toward i each other sufficiently to permit the arms to engage the pin when the folder is only partially retracted, the hammers engaging the pin after the folder has been entirely retracted and the former raised.

any desired type of staple driving mechanism may be employed. I have illustrated a mechanism similar to that shown in the previously mentioned patent to Kimball and this mechanism is arranged back of the lOO llO

staple forming mechanism. ,It is therefore necessary to provide means to transfer the staple from the staple forming position to the driving position. The means illus- 5 trated is most clearly shown in Figs. 3 and S. The staple having been formed on the plunger 29 is held in the groove thereof by. the hammers and their pivoted arms directly in front of an opening, 61, in the plate 51 and 2d the hammers forming guides to prevent the ends of the wire catching against the plates at the edges of the opening. The plunger is adapted to move through this opening carryin the staple to position over the anvil 62 of the driving mechanism. A spring-pressed retaining catch 63 pivoted to the stand at 04 engages the loop of the staple and holds it in place as the plunger is withdrawn. T he end of the plunger is recessed, as indicated at 65 to permit the catch to engage the loop of the staple. A plunger 66 descends as the plunger 29 is withdrawn and clamps the staple against the anvil, the plunger 66 being operated by a lever 67 pivoted at 68 controlled by a cam 69 on the rear cam shaft. The opening (31 inthe plates 5 and 2a are of substantially the size of the outside of the staple and thus assists in holding the staple in proper position for driving.

The blanks usually in the form of a strip of cardboard are fed across the machine between the guides 70 and 71. The feeding mechanism for the blanks as to its specific construction forms no part of my present invention. This mechanism is illustrated as of the same construction as shown in the aforesaid patent to Kimball No. 457,782.

0 The strip of cardboard is introduced between the guides 70 and 71 from one end thereof and is advanced at proper intervals by means of feed rollers 9ft and 95 between which it passes and to which an intermediate revolving motion is imparted as by means of a pawl 96 and ratchet 97, the latter being fixed to the shaft 98 of the roll 95 and the two rollers being geared together by suitable cog wheels 99 and 100. The

pawl 96 is carried by an arm 101 which is hung on the shaft 98 of the lower feed roller and operated in any suitable manner as for example by the grooved cam 102 on the shaft 4.

The staple having been received between the anvil and the plunger 66 is in position to be bent by the plungers 72 and 73 which bend the points and loop downwardly over the edges of the anvil. The plunger 72 is slotted as indicated at 7 1 so as not to interfere with the retaining catch 63. The plungers 72 and 73 are connected to a collar 75 and operated by a lever '76 pivoted at 77 and controlled by the cam 78 on the rear cam shaft. The anvil is moved to and from its operative position by a lever 79 pivoted at 80 and controlled by a cam 81 on the rear cam shaft against which cam the lever is held by a spring 82. The anvil is adapted to be retracted after the staple has been bent around it by the plungers '72 and T3, and the plunger 66 then moves downwardly forcing the points of the staple through the blank 83 lying on the bed with its edge projecting over the recess 84 in the 7 bed. T he staple is then in the position relative to the blank shown in Fig. 10. The plungers 66, 7s and 73 are mounted in a slot in the stand and are retained therein by the plate 51.

The loop of the staple is folded against the underside of the blank by a setting up tool comprising a slide 85 and a pivoted member 86. A fixed cam 87 cooperates with a cam surface 88 of the pivoted member 85 forcing the pivoted member upwardly at the end of its movement whereby the loop of the staple and the ends of the wire are bent closely against the underside of the card,the plunger (SG being held down against the top of the blank during the operation of the setting up tool. A spring 89 bears down upon the pivoted member holding it in proper position. The setting up tool is slidably mounted in a guide 90 secured to the bed and is operated by a lever 91 pivoted at 92 and controlled by a cam 93 on the rear cam shaft.
