Mass., assignor to Framingham, Mass, a corporation of Massachusetts I Application August 6, 1932, Serial No. 627,797

14 Claims.

This invention. relates to attaching tickets, marking tags, or the like to material such as fabric, and to supplying pins or other fastening elements to mechanism for transferring such elements from the supplying means to and into fastening position in superposed plies, as through a ticket and a piece of fabric.

Fastening elements such as the pins which are used in machines of this general class are commonly supplied in the usual pin strips, comprising a. paper strip or tape having longitudinal rows of similarly spaced perforations, the pins being disposed transversely of the strip through these perforations. These strips are fed into the machines where the pins are removed from the strip and delivered to an attaching mechanism by which they are inserted or driven through a ticket for securing the latter to the material. The mechanical operation of removing each pin from such a strip and arranging it in position to be inserted through a ticket, is usually performed in a manner to require at least a plurality of movements of the pin in different directions, and frequently the mechanism provided for'this purpose is quite complicated.

Objects of the present invention are to provide for simplifying the operationv of transferring a pin or other fastening element from a carrier or supply strip into position to be inserted or driven into fastening position in a ticket or the like; to reduce the number of mechanical movements and/or of moving parts required for this operation; and also to provide apparatus for these purposes having an improved construction and relative arrangement of parts.

Fig. 4 is a combined plan and side elevational view of a pin; and

Fig. 5 is a longitudinal section through a portion of a pin strip.

The features of this invention are illustrated as embodied in a pin ticket machine of the general type disclosed in my copending application Serial No. 565,466, filed September'28, 1931, to which reference may be had for a more complete understanding of the principles and mode of operation of that machine, but it will be evident that the embodiment selected for illustration herein is also well adapted for use with various machines or devices which are well known in the art.

The illustrated embodiment comprises a descending chute or guideway Ill formed of spaced vertical guide members II and I2 having opposed parallel grooves l3 and M (Fig. 2), the groove I! being adapted to receive the point end of a pin while the other groove l3 preferably is enlarged as by being undercut to receive the head end of a pin. This guideway is closed at its lower end by a transversely extending member it which provides a base for supporting a stack or vertical row of pins in the guldeway. At each side of this guideway, preferably just above the pin supporting surface of its base member iii, are aligned apertures I1 and 18.

The pin driving or inserting mechanism comprises a pin driver rod l9 carried by a reciprocable pin driver block or head 2| which is adapted to receive reciprocating motion from an oscillating pin 22 operating through an arcuate slot 23 in a frame member 24, or any other approved mechanism may be provided for this purpose. The pin 22 seats in a vertical slot 26 in the block 2|, as shown. .These parts are so arranged that the pin driver rod l9 may reciprocate through the aperture l1 along the supporting surface of the base member for engaging a pin resting thereon so as to force this pin from the guideway through the aperture I 8 and through a ticket.

It .will be apparent that the pin driver mechato engage the end of the slot just as this pin is approaching the end of its return stroke. This provides for an intermittent reciprocatory motion of the slide bar 21. This bar is guided during this movement by the frame 24 and a guide bracket 28 (Fig. 2). A contractile spring 29 is connected to a fixed post 3| and to a pin 32 on the slide bar 21 so as normally to urge the slide bar to the left, as viewed in Figs. 1 and 2.

The ticket attaching mechanism comprises a vertically movable anvil 33 having a transverse groove 34 (Fig. 2) in its upper surface to receive and guide the body or shank of a pin during attachment. This anvil is adapted to be moved upwardly substantially to the position shown in Fig. 1 to engage and hold a piece of fabric 36 and a ticket 3! firmly against the upwardly conone edge 38 of a rear frame member- 39 and a similar edge of a front member 4| (shown only in Fig. 2), thereby bowing or bending the ticket to a shape to receive an attaching pin. It will be understood that when the anvil is in the position shown in Fig. l, the pin receiving groove 34 therein is aligned with the aperture |8 in the guide member l2. Preferably this guide member is formed to provide a downwardly extending beak or point 42 which is provided with a groove (not shown) in its lower surface to form a continuation of the pin guiding channel provided by the aperture I8. This beak is adapted to engage the ticket and to assist in holding the latter in the desired position during attachment.

This ticket attaching mechanism may also include a mem er 43 which is disposed between the front and rear frame members 4| and 39 and is mounted to pivot on a pin 44. This member is provided with a spear-like point 46 adapted to enter between the plies of a ticket for spreading or separating such plies to receive and enclose the point of a pin. The under surface of the point 46 also assists in guiding the point of the pin between the plies. The member 43 is connected to the slide bar 21 by means of a pin 41 which operates in a slot 48 in the rear frame member 39. A spring pressed guide 49 may also be arranged yieldably to engage the longitudinal edge of a ticket for assisting in holding the latter in position for attachment.

In accordance with this invention fastening elements, here shown by way ofexample as pins for attaching the tickets, may be supplied continuously from a carrier or pin strip 5| by leading the strip toward the guideway l to a position to bring the ends of the pins carried thereby substantially into the opposed grooves I3 and H. The strip may then be led downwardly along the grooves for a suitable distance and then led away from the guideway. Once the pins enter the grooves l3 and I4 they are restrained and effectively held from moving away from the guideway with the strip It will be seen that as this strip is carried away the pins will be effectively separated therefrom and the free and unattached pins are therefore successively discharged or deposited one upon another in an approximately horizontal position forming a vertical row or stack of such pins in the guideway. Preferably the strip 5| is led away from the guideway around a suitable guide such as a roller 52 which may be mounted on the upright guide members I and II. It will be evident that other suitable guides or devices may be provided for directing the strip through the desired course to and from the guideway as will be understood by those skilled in the art when informed by this specification. While the strip carried from the guideway may be disposed of in any suitable manner, it is preferred to provide a winding spool or reel 56 for taking up this strip, and it is contemplated that this take-up spool may be operated with a step advance motion in properly timed relation in any approved manner to supply an additional pin substantially as the pin driver rod I9 is withdrawn to position for driving a pin. While the reel may be actuated in any suitable manner, as by a spring 55, as shown in Fig. 3, it is preferably operated by ratchet mechanism actuated by the slide bar 21 in substantially the same manner that the pin strip feeding mechanism is operated in my copending application previously identified herein.

Pins 53 of the type illustrated in Fig. 4 are par- 5 ticularly adapted for use with this apparatus. These pins comprise the usual shank or body portion and pointed end, but have a head in the form of a relatively small, approximately circular disk 54 having substantially the same thickness as the diameter of the body or shank, thereby enabling such pins to lie flatwise against each other in substantially parallel relation. The disk heads 54 may be readily formed by flattening the heads of pins of the common and well known form. These pins are disposed wholly on one side of the strip 5| and transversely thereof and are arranged substantially against each other with their head and pointed ends projecting freely beyond the longitudinal edges of the strip. The pins are releasably secured to the strip along their intermediate or shank portions by means of suitable adhesive material. Preferably the pins engage the adhesive substantially in line contact, as illustrated in Fig. 5. A broad band or contact between the pin and a tacky or hard drying adhesive film or coating would tend to cause tearing of the pin strip or to remove an objectionable amount of adhesive material upon removal of the pins in the manner described herein.

While any suitable water soluble gum or 9. normally moist or tacky cement (such as used, for example, on ordinary surgeons tape) may be employed with reasonable success as the adhesive 5 film or coating, I preferably use a plastic, nondrying adhesive (commonly termed self-sticking or pressure sensitive) upon which the smooth or polished surface of the pins will adhere without the necessity of moistening the coating and without taking up an excessive amount of the adhesive upon removal of the pins. Such a plastic adhesive may consist of a well masticated rubber compound suitably plasticized by resin or other softening agents well known to the art and applied to the sheet 5| in solution with a volatile solvent or by other known methods.

When applied under slight pressure to this deformable, non-stiffening adhesive coating, the pins are retained by a suction effect between their smooth surface and the yielding surface of the plastic adhesive. Hence it is not essential to limit the contact to an extremely thin band or line; for the adhesive has greater internal cohesion than adhesion to the polished surface of the pins 55 and consequently is not carried away by the pins when the latter are separated from the strip by axial movement thereof.

In the operation of this apparatus the ticket to be attached is advanced to a position substano0 tially above the anvil 33. The material to be ticketed is passed between the anvil and the ticket and the pin driver head 2| through its connection with the pin 22 is caused to begin its advance stroke from right to left, as viewed in Figs. 1 and 2. This advancing movement of the pin 22 permits the slide bar to advance under the influence of the spring 29 so that the lever 43 is moved downwardly, and this causes the spear-like point 46 to enter between and separate the plies of the ticket 31, while the latter is substantially flat so as to provide an opening or recess to receive and enclose the point of the pin. The anvil 33 then moves upwardly and bows 0r crimps the fabric material 36 and the ticket 31, forcing the latter against the concave edges 38 of the members 39 and 4| substantially in the manner illustrated in Fig. 1. The pin driver rod during its advance stroke passes from the aperture l1 along the pin supporting surface of the base member I5 and engages the head end of the lowermost pin and forces this pin through the aperture l8, through the ticket and the material, along the groove 34 in the anvil, and again through the material and into the body of the ticket. As the point of the pin is advanced to pierce the ticket the second time, the lower grooved edge of the spear-like point 46 guides the point of the pin into the opening formed by the point 46. While the point of the pin is being inserted in this way, the ticket is supported on its lower side by the cusp-like member 50. As the pin driver head 2| and the pin driver rod l9 are withdrawn on the return stroke to their extreme right-hand position, the slide bar is actuated to raise the member 43 out of the ticket.

From the foregoing it will be evident that the pin strip 5| constitutes a movable or traveling member or pin carrier which is adapted to convey pins substantially continually from a source of supply, as from a reel or other magazine, and that the pins so deliveredare received by the guiding means Ill and drected along a path determined by the grooves l3 and M, to the attaching means. While in the illustrated embodiment the pin strip has been shown as the movable member, it will be understood that the operation of detaching the pins from the strip may also be performed by effecting relative movement between the guiding means and the strip to cause the pins to enter the guiding means and subsequently separating these members,'or in other instances the strip 5| may remain substantially stationary and the guiding means may constitute the movable member. It will also be seen that the opposed grooves l3 and I4 maintain the pins properly aligned in superposed or side by side relation in a substantially vertical row. As the strip 5| is carried away fromthis guiding means about the roller 52, the pins become free and unattached. The operation of the pin driver rod I9 serves to remove a pin from the lower end of this row and as the pin driver rod is withdrawn from beneath the lowermost pin of this row the strip 5| is advanced to bring another pin against the surface 111, and this movement'of the strip 5| about the roller 52 serves to detach another pin from the strip and this pin then constitutes the uppermost of the row of free and unattached pins until the operation is repeated by operating the pin driver to remove another pin from the lower end of the row.

The term fastening element as used herein is intended to include fasteners which are similar to the illustrated type of pin having a flattened head as well as other forms of pins, as for example a pin consisting of the ordinary shank and pointed end but having no head, or a pin having its head formed in other ways, as by bending the shank to provide a head portion. Other forms of attaching elements which are somewhat similar to a pin, but not ordinarily described as such, are also intended to be included in the term fastening elements. For instance, straight or bent pieces of wire with or without point or head, but which may be used in an attaching machine to form a clip or staple,

may be fed or delivered to attachingmechanism in substantially the same manner.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
