ANIMAL IDENTIFICATION DEVICE AND APPLICATOR THEREFOR

Abstract: The tag (T) of this invention is provided with passageways which permit air to flow to the area around the stem (18). A pin (P) of this invention is provided with a base (19) of soft plastic attached to the stem (18) opposite the conical point (17), thereby avoiding the tendency of the hard plastic, to produce irritation of the ear. A hard plastic button (24) on that end of the stem, may be surrounded by the soft plastic (19). An applicator (A) for installing the tags and pins of this invention comprises a pair of opposed arms (32, 33), pivotally connected to opposed handles (34, 35), by which the arms (32, 33) may be brought together to push the pin (P) through an ear (10) of an animal, into engagement with a socket (14) on the opposite side of the tag (T).

Description: Description ANIMAL INDE TIFICATION DEVICE AND APPLICATOR THEREFOR Technical Field This invention relates to animal identification devices and applicators therefor. Background of the Invention Identification devices are used for numerous types of animals, including cattle, cows, sheep and swine, and have been used for a number of years. Earlier devices included metal clips which were pressed onto the ear of the animal. The identification device of the Norman J. Hayes U. S. pat¬ ent No. 3,260,007, which has become known throughout the United States and in other countries, comprises the com¬ bination of a pin and a tag. The tag, formed of a softer plastic, is provided with a body on which numbers or other identifying indicia may be placed, connected by a neck with a socket on the outside of the tag and a hole extending to said socket. The pin, formed of harder plastic, is provid¬ ed with a conical point at one end of a stem, with an an¬ nular base at the opposite end of the stem. An applicator, which operates similarly to a pair of pliers, is provided with a spring clip for holding the base of the pin against one arm of the applicator, with the opposite arm receiv¬ ing the socket, with the ear of the animal between the con¬ ical point of the pin and the tag. The handles of the ap- plicator are moved together to move the arms toward each other, so that the conical point of the pin will be forced through the ear, then into the hole in the tag and finally into the socket, to retain the tag and pin together. One disadvantage of the pin formed entirely of hard plastic, necessary to provide sufficient hardness and strength to permit the conical point and stem of the pin to be forced through the ear and into the socket of the tag, has been the fact that since the base of the pin, which engages the ear of the animal, rather than yielding somewhat with movement of the ear, remains rigid and thereby tends to irritate the ear. This may produce a wound which may become infected. An additional problem, albeit at times somewhat minor in nature, is the fact that, as the conical point of the pin passes through the ear, flesh from the hole is 5 pushed toward the side of the ear adjacent the tag. Al¬ though the tag is formed of soft plastic and therefore does not tend to irritate the ear as much as a hard plas¬ tic part would, the wound at the exit end is more pro¬ nounced than at the entrance end, due to the tendency for 10 flesh to be pushed through the hole in the ear. Thus, a close fitting tag may tend to retard the circulation of air to the wound at the exit end of the hole in the ear, thereby slowing the process of healing and increasing the possibility of infection. Of course, with the socket 15 on the outside, the tag will lie flat against the ear, thereby reducing the possibility of the tag being caught by a fence, tree limb or the like and tending to pull out of or damage the animal's ear. Additional types of tags and applicators have been dev- 20 eloped, including that of U. S. patent No. 3,812,859, which utilizes a spring clip of a type similar to that of U. S. patent No. 3,260,007 to hold a socket end of a tag mounted on one arm of the applicator, and a piercing and support needle mounted on the opposite arm of the applicator. This 25 needle engages a central hole in a pin which is formed of soft plastic but which must be reinforced by the needle in order to pierce the ear and which also must be provided with a conical metal ring at the outer end of the conical tip, so that the extreme end of the piercing needle will 30. first penetrate the ear, followed by the metal ring and then the remainder of the pin. The pin may be a separate pin, or may be molded integrally with another tag, also formed of soft plastic. Although this construction per¬ mits the soft plastic to engage the ear at the entrance 35 end of the hole to the ear, the applicator must be disinfected between each installation of the tag. The tip of the pierc¬ ing and support needle enters the ear of each animal in turn, so that any infection or the like present in one animal is likely to be carried to another animal. The inconvenience of dipping the applicator in an antiseptic solution between each installation of an identification device, as well as the inconvenience of carrying around the antiseptic solution in a container which must be opened to permit the stem of the applicator to be dipped into the solution and then closed to prevent the entry of dust, debris from an animal or the like, are both deterrents to the use of such a system. The socket for the pin is on the inside of the tag, thereby re¬ ducing the possibility of infection due to lack of air cir¬ culation. Another type of identification device is disclosed by U. S. patent No. 4,021,952, which device includes a pair of tags, one of which is provided with a socket adjacent one end and the other of which is provided with a laterally ex¬ tending stem formed integrally therewith. Each of these tags and the respective socket and stem are formed of soft plastic. The stem has an enlarged head and an axial hole, into which a metal pin having a conical tip may be slipped, with the base of the conical tip having a diameter corresponding to the enlarged head on the tag stem. The metal stem of the in reinforces the stem of the tag, while the metal conical tip of the pin not only pierces the ear but also displaces the hole leading into the socket so that the enlarged head of the hollow stem of the second tag will enter the socket and retain the two tags together. The metal pin is removed after a tag is installed, by making the stem of the pin longer than the stem of the second tag so that the metal pin, after installation of the tag, can be pushed from the opposite side of the ear to move the conical tip away from the socket. Thus, the conical tip can then be grasped by a workman and the installation pin removed. Of course, either the installation pin must be discarded after each installation or sterilized before reuse. The socket on the tag of the U. S. patent 4,021,952 is also placed adjacent the ear, so as to min¬ imize the area of the tag which engages the ear around the hole produced by installation, thereby permitting better circulation of air to the wound at the exit end of the hole in the ear. However, such a socket, normally produced by a boss or ring having a thickness which is considerably greater than the thickness of the tag, spaces the tag from the ear a corresponding distance, thereby increasing the possibility of the tag catching on a fence wire or the like and becoming lost or producing damage to the ear of the animal. A variation of the support type of tag stem is shown by U. S. patent No. 4,209,924, in which a steel point, closed and conical, is molded to the end of a hollow neck or stem of soft plastic, while an installation rod, as on a tool, is inserted in the hollow neck to push the tip and stop through the ear, then remove the rod without the need for sterilization between tag installations. Among the objects of this invention are to provide a novel animal identification device; to provide a novel ap¬ plicator particularly adapted for installation of such identification device? to provide such an identification device which includes a tag which is provided with a socket on the side opposite the ear for reception of the head of an attachment pin or the like; to provide such a tag hav¬ ing such a socket but which permits circulation of air to the wound at the exit end of the hole in the ear of the animal; to provide a novel pin which has a conical point on the stem of sufficient strength, such as corresponding to that of hard plastic, for penetration Of the ear and attachment to a tag having a socket therefor, but which is provided with a soft plastic surface at the base of the in or 0 f a second tag from which the pin extends; to provide such a pin which has a construction which readily transmits the force produced by an applicator for a tag and pin combination; to provide such an applicator which is particularly adapted to install the tag and pin of this invention; to provide such an applicator which more secure¬ ly holds the pin or a second tag having a pin extending therefrom; to provide the combination of an applicator, tag and pin or second tag having a pin which avoids the necessity for sterilization of any part following install- ation; to provide such an applicator which more securely receives a tag having a socket on the side away from the ear of the animal; and to provide each such tag with a socket, a pin with a conical point or tag provided with a stem having a conical point and applicator particularly adapted for installation of the tag and pin or dual tag combination, each of which is readily manufactured * and operates in an effective and efficient manner. Summary of the Invention An animal identification tag is provided with a socket having a well for receiving a conical point or the like of a stem of a pin on the opposite side of the tag from an ear or the like of an animal. This tag is provided with a plurality of passages for permitting a flow of air to the area around the stem, to promote healing of a wound prod- uced by the conical point when passing through the ear and perhaps extruding flesh from the hole so made. These pas¬ sages may be provided by undulations, such as alternating troughs and ridges extending toward the hole on the side of the tag which abuts the ear. Such passages may also extend through the head of the tag, from the outside to the inside, at positions around the socket, although the latter are less preferable to the former when mud or heavy dust conditions tend to clog the passages. An attachment pin, which extends from a base or from a head of a second taq, is formed of a hard material, such as plastic, and includes a stem extending from a conical point to a button OMPI which is imbedded in a softer plastic. The softer plastic engages the ear to reduce irritation sometimes produced by a hard plastic of the pin. To facilitate adherence of the soft plastic base to the hard plastic button, the stem has a groove adjacent the button, the side of the button oppos¬ ite the stem is convex and the button has a series of cir- cumferentially spaced holes. An applicator for installing the pin and tag has a pair of arms, connected across a com¬ mon pivot joint to handles for opening and closing the arms. One arm has a platform for the pin, provided by lat¬ erally extending wings and a rim around each side and its rear which acts as a stop for the pin. Each arm has a clip with a front slot and a tab at each side of the slot for respectively engaging the base of the pin on one arm, and the head of a tag on the other arm. Each clip is pivotal by side flanges on a pin and engages a compression spring at the rear. The opposite arm has a longitudinal slot to receive the socket of the tag and a ledge around the soc¬ ket engaged by the head of the tag. A perpendicular edge, around the ledge, engages the head of the tag to position the hole leading to the socket in alignment with the pin carried by the first arm.

OMPI , WIPO Detailed Description of the Invention As illustrated in Fig. 1 of the drawings, a tag T of this invention may be attached by a pin P to an ear 10 of the head H of an animal such as a steer, cow, calf, sheep or a member of the swine family. The relative size of the tag may decrease as the size of the animal decreases. Each of the pin P and tag T is an improvement over the pin and tag of U. S. patent No. 3,260,007. Thus, the tag includes a body 11 on which a numeral or other identifying indicia may be placed, with a neck 12 tapering upwardly at each side to an annular head 13 from which a socket 14 extends outwardly at a central position. A central axial hole 15 leads to an outer well 16, for a purpose described later. The pin P, utilized with the tag T of this invention, may be similar to the type shown by the aforesaid U. S. patent 3,260,007, in order to overcome the disadvantages thereof through ventilation by the construction of tag T, in accor¬ dance with this invention, which produces faster healing of the wound produced by penetration of the ear by the pin. However, the preferred construction of the pin, in accor¬ dance with this invention, as in Figs. 2 and 6, include a conical point 17 and a stem 18 which are formed of a hard plastic, such as glass filled nylon, while stem 18 is at¬ tached to a base 19. As the pin point 17 is pushed through the ear and into the hole 15 of the tag, it will expand the socket 14, then permit the socket to retract as soon as the point 17 reaches the well 16, in which the base of the conical point is seated to prevent withdrawal of the pin. At that time, a portion of stem 13 will occupy hole 15, as in the position of Fig. 2. Pin P may be installed by an applicator similar to that of the aforesaid U. S. patent 3,260,007, but preferably further constructed in accor¬ dance with this invention, as exemplified in Figs. 10-13. A disadvantage of making the entire pin P of hard plas- tic in order to provide a conical point which is sufficiently hard and a stem which is sufficiently strong to penetrate the ear and engage socket 14, is that a base 19 of the tag, when made of hard plastic, will rub against the side of the ear and thereby rub a sore spot on the ear, which may be¬ come infected. However, the tag T, which engages the op- posite side of the ear, does not produce the same effect, since it is formed of a relatively soft plastic material, such, as polyurethane. Thus, the base 19 of the pin is formed of a soft plastic, in accordance with this invention, as described later. In accordance with this invention, as shown in Figs. 3-5, a series of troughs 20, such as three, extend radi¬ ally inwardly from the periphery of head 13 to the inside of hole 15, as well as fron the area of neck 12, with the troughs 20 being equally spaced and being separated by ridges 21 which abut the ear of the animal, as will be evident from Fiq. 2. As shown, trouqhs 20, as well as ridges 21, are disposed 120° apart, although the number and spacing of the troughs and ridges may vary from that shown. Preferably, the outer edge of one trough is centered on neck 12 to insure air flow to the bottom of the area around hole 15, with the opposite ridge 21 centered at the upper end of head 13. Thus, with the three troughs and ridges shown, the centers of the remaining two troughs will be at 60° from upper center. The oblique top plan of Fig. 4 is a view looking directly into the trough 20 of Fig. 3, the center of which is located 60° to the right of upper cen¬ ter thereof. Each ridge 21 narrows as it approaches the center hole 15, so that each trough 20 which flanks it, will have a width, at the hole 15, approaching the diameter of the hole. The inner end 22 of each ridge 21 may occupy a minimum portion of the circumference of the hole, as in Figs. 4 and 5, and the end 22 may slant outwardly to pro¬ vide additional space around hole 15. Between the bottom of each trough 20 and the crest of each ridge 21, the lat- ' eral contour may curve smoothly, as in Fiq. 4, to form un¬ dulations. Thus, the troughs 20 provide ventilation to the area of the ear 10 which is penetrated by pin P upon _CMFI Wli'CJ - - installation, i.e. around the stem 18 where the conical point 17 has pushed through the skin and perhaps wedged outwardly a circle of flesh. The presence of the troughs 2Q, which occupy only a portion of the periphery of the head 13 and. the circumferential extent as well as the width of which may vary from that shown, insures that air for ventilation of the wound produced by penetration of the pin through the ear will not only assist in curing the wound, but also act to deter or prevent an infection which is sometimes produced with such a type of ear tag. As stated previously, the base 19 of the pin is formed of a soft plastic, conveniently the same material, such as polyurethane, as that utilized in making the tag T and is molded directly onto the stem 18, around a button 24 of the stem which extends laterally outwardly within the base 19. A groove 25 extends around the stem adjacent the button 24 and four or other suitable number of holes 26, such as oval, extend through the button, as in Fig. 7, in order to improve the attachment of the softer plastic of base 19 to the stem and to insure the maximum amount of soft plastic engaging the ear of the animal. Conveniently, the underside of button 24 may be convex at 27, opposite stem 18, while the periphery of the base 19, generally out¬ wardly from the button 22, may be provided with annular sides 28 which taper outwardly toward each other. Point 17, stem 18 and button 24 of the pin P may be molded in a tag T 1 of Fig. 7, corresponding in size and shape or differing from tag T of Fig. 1 but shown in Fig. 7 as having a corresponding neck 12' extending to a pin base 19' which is integral with the remainder of the tag. Except where joined to neck 12', base 19' is similar to base 19 of the pin of Fig. 5, while button 24 and the re¬ maining parts, i.e. the conical point 17, stem 18 and groove 25, may be the same as shown in Fig. 6. n alternative ventilation construction of the tag, shown in Fig. 3, may be utilized under appropriate cir¬ cumstances, by providing a series of apertures 30, such OMPI as four, which slant inwardly from the base of socket 14 to the underside of a head 13' , in order to transfer air to the underside of the tag and to the area of the wound produced by penetration of the pin. There are certain en- vironments, such as where mud or blowing dust are prevalent, in which such apertures 30 may tend to clog, in which the preferred form of the invention of Figs. 1-5 would more desirably be utilized. The tag T of this invention may be produced by inject- ing the plastic into a mold cavity having essentially the same size and shape as the tag, with allowance for shrink¬ age, with the mold being separable longitudinally into two halves, i.e. around the edges of the tag, for removal of the completed tag. Conveniently, a plunger which pushes the completed tag out of one half of the mold, may be cylin¬ drical and engage the outer end of the boss 14, so as to push the tag off the pins by which the hole 15 and well 16 are produced. Additional ejection pins may engage approp¬ riate spots on the body 11 of the tag. The composite pin of this invention may similarly be produced in a split mold but having movable inserts which initially form the button 23 and groove 24 " when hard plas¬ tic, such as glass filled nylon, is injected into the mold, as at the button, but are then withdrawn to leave a cavity corresponding to base 19, after which a softer plastic, such as polyurethane, may be injected into the base-forming cavity. The alternative, of course, would be to form the conical point 17, stem 18, button 23 and groove 24 of hard plastic and then insert the stem and button into a mold cav- ity in which the base 19 is formed. However, this latter is especially time consuming and thus considerably more ex¬ pensive than the molding of the pin in one mold cavity. Boy, Farrel, McNeil, Nissei and Van Dorn molding machines have been found to be suitable for this purpose. When the in is incorporated in a second tag, such as tag T' of Fig. 6, a similar mold may be utilized, except that the cavity for forming the tag is similar to the portion of a mold OMPI cavity in which the neck 12 and body 11 are formed. An applicator, by which the pin and tag are held and then the pin thrust through the ear of the animal to lock the pin to the tag with the stem of the pin remaining in the ear, may be constructed in accordance with this inven¬ tion, such as applicator A illustrated in Figs. 9-17. As shown in Figs. 9 and 10, an applicator A, similar to a pair of pliers and often referred to as pliers, is provided with an arm 32 adapted to carry the pin P, as in Fig. 3, and an opposed arm 33 adapted to carry the tag T. Arm 32 is moved by a handle 34 and arm 33 is moved by a handle 35, with a pivot ring 36 of Fig. 9 connecting arm 33 with handle 35 and an opposed, corresponding pivot ring 37, shown in Figs. 14 and 15, connecting arm 32 with handle 34. A pin 38 ex- tends through an appropriate hole in each of the opposed rings 36 and 37, as described later. After the pin and tag have been placed on opposite sides of the ear and the ear 10 disposed in the space between the pin P and tag T, with the applicator in the position of Fig. 10, handles 34 and 35 may be moved toward each other, so that arms 32 and 33 will pivot about pin 38, from the position of Fig. 10 to the position of Fig. 9 and pin P will be thrust through the ear of the animal and into socket 14 of the tag, so that cone tip 17 will seat in well 16. in P is retained on arm 32 by a clip 39 and tag T is retained on arm 33 by a corresponding clip 40. Clip 39 has an angular flange 41 at each side and is pivoted on a pin 42 which extends through each flange adjacent the inner edge of the latter, pin 42 conveniently being a spring type pin, i.e. in a hollow rolled form with a longitudinal slot and formed of resilient material with the ends turned out¬ wardly to clamp against the respective flange 41. Similar¬ ly, clip 40 for tag T is provided with a flange 43 at each side, each of which is pivoted on a pin 44, which extends through the arm 33 adjacent the inner surface thereof and may be formed in the same manner as pin 42. A slot 46 in the front end of clip 39, as in Fig. 12, accommodates stem 18 of nin P and preferably has a width a few thousandths of an inch greater than stem 18 of the pin so as to center the pin. A pair of tabs 47 of clip 39 engage the base 19 of the pin, on each side of slot 46. A punched offset 48 at the opposite end of clip 39, as in Fig. 12, engages one end of coiled spring 49 of Fig. 10, which urges the tabs 47 of the clip against the base of the pin, while a well 50 of Fig. 14 receives the opposite end of spring 49. A slot 51 in the outer end of clip 40, shown in Fig. 13, has sufficient width to clear the base of cone tip 17 of pin P as it moves into the socket of the tag, while a pair of tabs 52 engage the inner surface of head 13 of the tag on each side of slot 51. Similar to clip 39, a punched off¬ set 53 in the opposite end of clip 40 engages one end of a spring 54, the opposite end of which is received in a well 55 of Fig. 16, To accommodate flanges 41 of clip 39, a pair of oppositely disposed grooves 56 of Fig. 14 extend downwardly from the upper edge of arm 32 past a transverse hole 57, shown in dotted lines and through which pin 42 of Figs. 9 and 10 extends, while a corresponding pair of grooves 58 of Fig. 16 extend upwardly, on each side, from the lower edge of arm 32 past a similar transverse hole 57, through which pin 44 extends, to accommodate flan¬ ges 43. The outer end of arm 32, as in Figs. 11, 12 and 14 and in accordance with this invention, is provided with a plat¬ form 60 on which the base 19 of pin P rests and against which the pin is held by clip 39. The front end of plat¬ form 60 is open, as shown, while a wing 61 extends laterally from each side of arm 32 to enlarge the width of the plat¬ form, A rim 62 at each side facilitates the placement of the pin on the platform, the distance between the rims being greater than the diameter of head 13 of the pin, while an arcuate curved rear wall 63 may be positioned so that when the edge of head 13 engages the rear wall, the pin will be centered longitudinally, the lateral centering of the pin by tabs 47 of clip 39 being described previously. ( OMFI As in Figs. 11 and 16, the outer end of arm 33 is provided with a slot 64 which, accommodates movement of the pin through, the tag socket and thus has a width approximately the diameter of well 16 in socket 14. Spaced from the un- derside of arm 33 a distance corresponding to the height of socket 14 of tag T, is a ledge 65 against which the end of socket 14 abuts, to resist the thrust of the pin P through the hole 15 in the tag and into the well 16. The remainder of head 13 abuts the underside of arm 33 and the tag is re- tained by clip 40. The inner edge 66 of the groove formed by ledge 65, as in Fig. 16, may be positioned so as to be abutted by socket 14 and thereby position the tag socket in alignment with pin P. It will be understood that, al¬ though the parts associated with arms 32 and 33 are des- cribed with reference to the top and bottom, or underside, of each, these terms are only relative and are based upon the position in which the parts of the applicator are shown in Figs. 9 and 10. Thus, it will be understood that, when the applicator A is utilized to install a tag in the ear of an animal, as in Fig. 1, the applicator may be held in a vertical position, with the handles 34 and .35 upright and beneath the ear, as well as in a horizontal position or any angle between vertical and horizontal. Also, the ear of the animal may be twisted so that the applicator may be held at a different angle to the horizontal. Additional parts of the applicator include a spring 69 which extends between abutments 70 and 71 of handles 34 and 35, respectively, to urge apart the handles and therefore the respective arms 32 and 33. The opposite ends of spring 69 may be received in a well 72 in handle 34 and a well 73 in handle 35, each of these wells being shown in dotted lines in Fig. 10. Pin 38 of Figs. 9 and 10 extends through a hole 75 in ring 36 of Fig. 17 and a hole 76 in ring 37 of Fig. 15. When the rings 36 and 37 are interfitted together, pin 38 may be inserted into the holes 75 and 76, aliqninq these holes as it does so. One end of pin 38 may be con¬ veniently provided with a flange adapted to engage a O PI countersink 77 at the outer edge of either hole 75 or 76 with the opposite end of pin 38 having a conventional slot or groove into which a conventional split retaining ring may be spread by a conventional tool for insertion, the retaining ring being accommodated by the opposite counter¬ sink 77. An annular groove 78, on the inside of each ring 36 and 37, as in Figs. 15 and 17, accommodates a conven¬ tional bowed spring washer which maintains a slight clear¬ ance between rings 36 and 37, thereby increasing the ease with which the applicator may be operated. For more ac¬ curate interfitting of the two halves of the applicator together, arm 32 may be provided with an arcuate surface 79 and handle 34 with an opposed arcuate surface 80, for encircling opposed arcuate portions of ring 36, as in Figs. 9 and 1Q, while arm 33 may be provided with an arcuate sur¬ face 81 of Fig. 17 and handle 35 with an arcuate surface corresponding to surface 79 but in opposed position to sur¬ face 80, for encircling opposed arcuate portions of ring 37. To limit the. opening movement of the arms and handles, an abutment 83 may be formed at the rear edge of surface 79 of handle 34 and an abutment 84 on handle 35, while an abutment 85 may be formed at the front edge of arcuate sur¬ face 80 and an abutment 86 on arm 33. When moved to the open position of Fig.10, abutments 83 and 84 and abutments 85 and 86 will be in engagement, as shown. For limiting closing movement of the arms and handles, abutments 87 and 88 may be formed on arms 32 and 33, respectively, so that these abutments will engage when the applicator is moved to the closed position of Fig. 9. The relative position of abutments 83 and 86 are shown in Figs. 15 and 17, respec¬ tively, of abutments 85 and 87 in Fig. 14 and of abutments 84 and 88 in Fig. 16. As will be evident, the applicator of this invention requires only that the pin and tag be placed in position, the arms of the applicator placed over the ear or the like of the animal and the handles squeezed together, whereupon the applicator may be slipped off the ear. This ease in use contrasts with those applicators having a stem attached to one jaw, which reinforces the pin, but which requires the applicator to be fully opened aqain, after closinq, before it can be removed. Althouqh a preferred embodiment of a pin, tag and ap¬ plicator of this invention have been illustrated and des¬ cribed and additional embodiments also illustrated and described, it will be understood that other embodiments may exist and variations thereof used, without departing from the spirit and scope of this invention.
