2,996,720 TICKET FEEDING APPARATUS FOR HAND STAPLING MACHINES James G. Mackechnie, 1 Overlook Way, Winchester, Mass. Filed Nov. 30, 1959, Ser. No. 856,294 15 Claims. (Cl. 1-4108) This invention relates to stapling machines and particularly to hand staplers of the so-called plier type in which driver and clincher arm assemblies are relatively movable to drive and clinch a staple to an article or articles presented thereto.

More specifically the invention is directed to a tag or ticket feeding and folding mechanism or attachment which is especially adapted for incorporation in a plier type hand stapler and which is operable to feed between the driver and the clincher a tag or ticket at the free end of a strip supply carried by the stapler and to insert the same in folded condition for affixing a ticket to an article presented thereto in the normal manner, and, thereafter as the otherwise ordinary stapling operation takes place to automatically sever the folded ticket from the end of the strip and to advance the next ticket of the strip into position for a succeeding stapling operation.

A primary object of the invention is to provide a known type of commercial hand stapler with simplified mechanism operable as above set forth so as to enable tags or tickets to be aflixed to a variety of articles, as for identification purposes. The invention is particularly useful in placing tickets on garments for identification purposes, one example being the temporary ticketing of garment pieces in a dry cleaning or laundry establishment for proper identification and return to the customer.

Heretofore, apparatus satisfactorily adapted for stapling tags to garments and other articles in dry cleaning establishments and laundries have been available as a relatively specialized type of equipment and normally for handling a huge volume of pieces. Consequently they have been found practical only for locations where the expense is justified and the problems of maintenance of relatively complicated machinery is of secondary concern. Accordingly, another object of the invention is to provide an inexpensive piece of equipment for the purpose assigned which will be readily available to those handling a moderate or small volume of work and which will be Well within the means of the operator of smaller establishments. At the same time devices of the present invention may also be advantageously used where large volume ticketing operations are required and inexpensive and simplified hand portable devices can oifer superior results from the standpoint of convenience and otherwise.

The device of the present invention is particularly designed-for use in folding an identification ticket, or ticket used for other purposes, and. stapling it at-the edge of a I garment or other flat piece but it may be used as well' in tagging other articles of a cylindrical or other form having a relatively small cross-sectional dimension such as wire, plant stems and the like. In the latter instance the ticket or tag will normally be stapled with the portions adjacent the fold line thereof in surrounding relation to the article and the staple wire piercing the material of the ticket only. g The particular novelty of the invention and the above and other objects and advantages of the same will be apparent from the following description.

Illustrated in FIG. 1 is a commercial form of hand stapler with the device of this present invention mounted on it. The stapler by itself is a well known piece of equipment and will be recognized in the trade as a Bostitch plier-type stapler identified under model designation P6 Plier. Essentially the stapler unit comprises a driver arm assembly indicated at '10; a clincher arm assembly at 12 (pivoted relative to the driver arm at 14); a magazine assembly at 16 (also pivoted at 14 relative to the driver arm and clincher arm), and an operating lever at 18. Lever 18 is pivoted intermediate its ends at 20 to the clincher arm and at its inner end is hooked over a pin at 22 fixed in the driver arm. A magazine cover spring is at 24 and an elevating spring is at 26. Spring 26 is caught at one end on the lever pivot pin at 20 with a midsection thereof resting on the clincher arm and bearing at its other end against the underside of the magazine. The end of the magazine sliding cover is seen at 28 and as will be recognized is manipulated in known fashion to insert a supply of staples in the magazine.

As the stapler is grasped in the hand after the manner of a pair of pliers the lever can be raised to bring the clincher arm and an anvil (not shown) at the end 30 of the arm toward the magazine assembly. The clincher arm then forces the magazine upwardly against a driver (not shown) 'at the end of arm 10 to drive a staple from the magazine through the material of an article placed over the end 30 and in the conventional fashion clinches the staple on the :anvil. The springs serve to return the parts to the position of FIG. 1 whereupon an article can be removed with the staple fixed to it.

The invention as shown in the drawings has been in corporated in the assembly of a plier type stapler as generally described above. Briefly, there is added to the stapler a saddle type bracket 31, fixed by screws 32 to the driver arm and on which is carried a ticket guiding and feeding channel generally designated by numeral 34, and a feeding and folding arm 36 pivoted on a pivot screw 32 also fixing bracket 31 to the arm 32; a ticket roll housing 38 having an exit at 40 for a strip of tickets thereon to feed through to channel 34, the casing 38 being removably mounted on a bracket 42 fixed in any suitable manner (not shown) to the driver arm at the far side of FIG. 1; a ticket advancing arm 44 fixed at 46 (see FIG. 3) to the clincher arm, the arm 44 extending upwardly to cooperate with the channel 34 to advance the strip of tickets therein as will be later described.

Preferably the tickets adapted for use in the device are as shown by FIG. 4. In roll form the strip of tickets is mounted on the spindle of the casing with the free end of the roll passing through the exit 40 above the guide channel 34. The line of separation between each ticket 50 of the roll is a scored or weakened transverse line 52 so that the endmost free end ticket may be readily severed from the strip. Each ticket is also provided with FIG. 2 on an enlarged scale is a front elevational view a central aperture or hole 54 for ticket advancing purposes and laterally at each edge of a hole 54 are aligned weakened lines 56 defining a mid fold line for embracing the edge of a flat article or encircling an article of a linear character such as wire, etc.

The device as generally described operates as follows: The strip of tickets at the beginning of a stapling operation extends from the housing 38 through the channel 34 (FIG. 5) to position the hole 54 of an endrnost ticket in a predetermined position opposite the spacing between the driver and clincher arm assemblies. The rocker or folding arm 36 is manually swung downwardly, picking up the endrnost ticket by engaging the exposed hole 54. Continued movement of the arm 36 pulls a portion of the ticket strip from the channel and inserts the lowermost ticket between the spaced arms 12 and 16. Movement of the arm 36 past the arm 16 causes the ticket to become creased or folded along the weakened lines 56, disposed on opposite sides of the hole 54. The lines 56 are such that once creased, a ticket will remain in a folded condition. The folding arm 36 may then be released, its spring 58 will return it to its FIG. 1 position. When the folding arm is returned by its spring 58 (FIG. 1) the friction between the ticket and arm serves to maintain the folded ticket in place between the arms 12 and 16, as shown in FIG. 6. On return of the arm 36 the operator then merely places the edge of a garment or other article to be tagged between the ticket halves and operates the stapler in conventional manner.

As shown by FIG. 7, the edge of an article 60 which has been inserted between the arms is thus tagged as the driver and clincher arms are brought together. Relative movement between the clincher and driver arms from the position of FIG. 6 to the position of FIG. 7 causes the following interaction of the various elements of the device.

As for severing the end ticket, the clincher arm first moves toward the driver until the halves of the partially folded end ticket are pressed flatly on opposite surfaces at the edge of the article 60. At this stage the clincher 12 has moved towards the driver sufiiciently to bear against the magazine '16 and would be substantially in the relative position shown by full lines in FIG. 7. Insofar as the ticket being applied is concerned it will be noted that travel of the end edge 30 of the clincher further from this position toward the driver, while the ticket and article are squeezed together and the staple wire is being driven, will cause the end of the ticket attached to the strip to double back over the edge 62 of the guide channel. Upward movement of the clincher arm 12 moves the arm 44 upwardly and a projection 64 carried by the arm 44 engages the ticket strip as shown in FIGS. 6 and 7. The ticket size is related to the parts of the device so that this doubling back over the edge 62 occurs approximately at the weakened transverse separation line 52 of a ticket. The upward movement of the clincher arm 12 and magazine assembly causes the ticket strip to be severed, or pulled apart, along the separation line 52 which, as described above, is located approximately at the edge 62 of the guide channel.

As the stapled ticket is torn from the strip the succeeding endrnost ticket is (FIG. 7), of course, positioned with its leading edge at the exit end of the guide channel. However, the advancing arm 44 with a ticket hole engaging projection 64 has been carried from the position shown in FIG. 6 upwardly to its position shown by FIG. 7 where the projection 64 engages the hole of the now next endrnost ticket of the strip. It will thus be seen that as the article with a ticket stapled to it is withdrawn from between the stapler arms and the parts of the stapler returned to their inactive position as shown in FIG. 5, the projection 64 has advanced the ticket strip to bring the hole of the endrnost ticket into position for engage-- ment by the folding arm for a succeeding cycle of operation.

It will also be noted after the folding arm has inserted the endrnost ticket in partially folded condition between the arms a ticket holding projection 66 engages the ticket hole 54 against return movement in the guide channel. The projection 66 retains the strip against rearward movement as the advancing projection 64 bears against the ticket in its upward travel from the position of FIG. 6 to that of FIG. 7. The frictional rubbing movement of projection 64 against the back of the ticket could otherwise cause a reverse travel of the strip.

In broad outline the tickets 50 of the strip supply may thus be successively stapled at the edges of a series of articles. The tickets may bear any desired indicia as consecutive numbering and varying colors to accommodate any system of identification which might be used. The various elements of the structure wil now be described in detail.

The ticket strip guide means designated generally by the numeral 34 is formed by a rear plate 70 and an overlying front plate 72 attached to it. Rear plate 70 is, in the construction shown, an integral part of the bracket 31 attachment arm plates lying at each side of the driver arm assembly 10, these arms being directed rearwardly at each side of the plate 70 and fixed by the mounting screws 32. In the upper portion of plate 70 which stands upwardly of the driver arm a recessed ticket groove 74 is formed (FIG. 8) to receive the ticket strip (see also FIG. 2) and guide the same. Centrally of the groove is an elongated slot 76 extending substantially from the top to the bottom of the upper extension of the plate for receiving the advancing hook or projection 64.

Against the raised edges 78 at the sides of the recessed plate portion the front plate 72 is fastened as 'by the screws 80 to overlie both the upper and lower portions of the rear plate. The front plate 72 is also provided with a central longitudinal slot 82 matching the slot 76. Below slot 82 is a leaf spring 84 riveted centrally to the plate 72 at its upper end and at its lower end has the check projection 66 fixed to it and extending through an opening 86 of plate 72 for contact with tickets passing through the guide. As seen in FIG. 3 the lower section of the rear plate is formed with an apron 88 to insure engagement of the projection 66 with the ticket hole.

It will be further noted that the lower attaching screws 80 are provided with spacers 90 (FIG. 3) for greater separation of the plates at the bottom end of the upper plate portions for cooperation with the advancing hook 64.

The advancing hook or projection 64 is formed as a nib on a sliding piece 92 having a reduced shoulder at 94 to slide up and down in the slot 76 and a stem: passing through the inturned end 45 of advancing arm 44. A spring 96 around the stem holds the slide 92 yieldably pressed rearwardly against the recessed inner surface 74, the spring being seated against the end 45 and cap 98 threaded on the stern. Thus a snug fit of the slide 92 during its travel back and forth in the slot is assured and adjustment of spring tension may be had to compensate for any chance frictional binding of the slide 92 or inturned end 45 against the plate surfaces.

As will be seen from FIG. 5 and FIG. 8 the hook 64 engages the lower edge of a ticket hole 54 while the 1ongitudinal half portions laterally thereof are flexed forwardly by the underlying buttons located as at 100 in the lower section of [the recessed groove 74 (see also FIG. 6). The flexing action of the buttons 100 on the ticket imparts a stiffness to the ticket in the area of the hook engagement with the ticket hole. Thus when the hook engages the hole at the top of its stroke, as in FIG. 7, and advances the strip downwardly to the position of FIG. 5 the stiffness imparted to the ticket prevents any chance disengagement of the hook from the hole 54.

It will be realized that the greater separation of the plates 70 and 72 by spacers 90 at the bottom of the recessed portion 74 is provided to enable the strip to advance (on manipulation of the rocker arm 36) and be drawn over the hook during the feeding operation of inserting the partially folded end ticket between the driver and clincher (FIG. to FIG. 6). With the increased spacing between the plates at this point there is no chance for the projecting hook 64 to tear the ticket as the latter is drawn over it. For added insurance the slot 82 is provided in the outer plate. Furthermore while the ticket frictionally rubs to a certain extent against the hook and is in turn frictionally rubbed by the hook on upward travel of the hook from the position of FIG. 6 to that of FIG. 7, the slot 82 permits the ticket to give along its central section and thus assist in avoiding any excessive drag which might otherwise damage the paper material. It Will also be seen that the spring mounting 100 keeps the projection 64 rearwardly in the recess during its upward travel.

Insofar as the projection 66 is concerned it will readily be seen from FIG. 5 that the mounting of this projection on leaf spring 84 means that forward movement of the ticket strip may readily push the projection out of the way and that the leaf spring may be of a strength to merely return the projection toward the apron 88 so as to engage a hole 54 for holding purposes only. Thus projection 66 causes no excessive drag or rubbing action on the ticket.

The feeding and folding rocker 36 is provided with arms straddling the driver arm and pivoted on the screws 32' as best seen in FIG. 2. A folding bar 110 connects the arms adjacent the outer end of the rocker and central-ly of the bar is a projection 112 to pick up the hole of the endmost ticket and insert the latter into position as in FIG. 6. Bridged across the top of the arms is a stop bar 114 which as best seen in FIG. 6 serves to contact the end face at 30 of the clincher arm to limit the travel of the rocker and position the partially folded end ticket in the proper relationship between the stapler arms.

The amount of clearance necessary between the end 30 and the edge 62 is sufficient to accommodate the material of an article duiing a stapling operation without damage to the article. It will be realized that articles with materials of varying thicknesses will be stapled when using the .device for tagging garments for identification purposes.

Accordingly, the amount of clearance will normally be that sufiicient to properly handle the thickest material which might be presented to the device. If by chance the end ticket is not completely severed, it will be realized that on parting movement of the driver and clincher the rocker 36 can be actuated to bring the stop bar 114 down against the end of the clincher arm (as in FIG. 6). The lower edge of the bar 114 provides a cutting edge for tearing of the stapled ticket while at the same time the rocker 36 feeds the 'next'ticket between the stapler arms.

For tagging articles such as wire, plant stems, and other articles of a similarly small diameter the clincher arm may furthermore be modified by providing a slightdepression transversely of the arm as shown at 120 in the various views. It will be appreciated that clearance is thus provided for a proper stapling operation and that the ticket will then be wrapped around this type of article. The depression may, of course, be of various dimensions to accommodate different articles for tagging and may be furthermore selectively located to provide a tight or loose wrap of the identifying ticket.
