NEW ZEALAND
PATENTS ACT 19 5 3 COMPLETE SPECIFICATION "IMPROVEMENTS IN ANIMAL EAR TAGS"
I/WE- GEOFFREY NOEL DUMBRELL of 403 Glenferrie Road,
Malvern, Victoria 3144, Australia, an Australian citizen hereby declare the invention, for which I/we pray that a patent may be granted to me/-*is-> and the method by which it is to be performed, to be particularly described in and by the following statement
198938
This invention relates to an animal ear tag and it refers particularly to a two-piece ear tag of the self-piercing type comprising a male member and a female member the latter having an opening to receive the head of a stem of the male member, the stem head being capable of forming an opening in the ear of an animal to which the tag is to be attached, and one of said members having a tag of suitable size and shape to carry indicia to show ownership and/or other information.
It has been proposed to provide such ear tags and plier-like applicators for the tags - see New Zealand Patent
Specification No. 162710/164351 and Australian Patent Specification No: 58854/65. such applicators there is a pin of relatively small diameter onto which the male member is placed, the outer end of the pin extending through the male member, and the outer end of the pin effects the initial operation of piercing the ear. The stem of the male member is then forced through the opening to extend the opening and pass through the ear and into the opening in the female member, the stem of the male member having a head of enlarged size which acts to hold the two members in assembled relationship on opposite sides of an animal's ear once it has passed through the opening in the female member.
164351
In the said New Zealand Patent specification No* 162710/ the stem of the male member is described as having at-' Its 'v outer end a flange and at that
198938
hard material through which the end of the pin projects, as mentioned above.
Australian -Patent Specification ' No: 58854/65 -describes a male member made' of relatively rigid material and New Zealand
162710/164351
Patent Specification / describes a male member of softer material having a hard metal insert at the outer end of the stem.
In both these proposed constructions the pin (of the applicator pliers) for holding the male member is of relatively small diameter and is long enough to project right through the male member and beyond the outer end of its stem, and it is believed that, in use, the pin would tend to bend so that it would no longer operate correctly to force the head of the stem (including the hollow spike in the latter case) through the opening of the female member. Also, as the end of the pin penetrates the ears of successive animals it is clear that cross-infection can occur. Further, the two members of the tag may be pressed together, tightly on opposite sides of the ear, so as to prevent a free circulation of air about the opening which has been made in the ear of the animal, and that can lead to infection.
This invention has been devised with the object of providing an ear tag of the same general type as described and illustrated in the two said patent specifications, and applicator pliers for use in applying the ear tags, which will not possess the disadvantages mentioned above;.

198938
Another object is to provide an ear tag of the type mentioned wherein the two members when fitted together, will be held in spaced-apart relationship such that there can be a circulation of air between the animal's ear and the parts of the tag, and wherein once the two parts are assembled it will be very difficult to pull them apart.
The constructions of ear tag previously proposed and described in th^ Australian Specification Nos. 58854-/65 and New Zealand Patent Specification No. 162710/164351
/ effect a piercing and spreading apart of the flesh of
0 the ears to which the tags are applied and do not form clear-
cut openings in the ears. Yet another object of this invention is to provide an ear tag which will cut an opening in the ear to which it is applied, such that the cut will heal more readily than a pierced opening.
A further object is to provide an ear tag of the type mentioned having a male tag member of polyurethane or other relatively soft material and a hardened spike or pointed head at the outer end of the stem of that male member which is adapted to fit on a pin (of the applicator pliers) shorter 20 and of larger diameter than hitherto provided, and which will be more economical to make and lend itself more readily to mass production procedures than that described in New Zealand patent Specification No. 162710/164351.
A still further object is to provide an applicator ■^5 for ear tags of the type mentioned which will not possess the disadvantages mentioned above, particularly those

associated with a pin of relatively small diameter and substantial length, and which will not lead to cross-infection from one animal to another.
objects in view provides an ear tag of the type mentioned consisting of a male member and a female member adapted to be fastened together in spaced relationship, wherein said male member has a hollow stem of relatively flexible material with a neck of reduced external dimension at the outer end of the stem, and a relatively rigid pointed head member having an integral shank fastened in the outer end portion of the hollow stem, the tapered and pointed outer end part of the head member projecting beyond the neck and the maximum transverse cross-sectional size of that tapered outer end part being greater than that of the neck, and the shank having means for locking it in position in said / said pointed head member being imperforate and being adapted to penetrate an ear of a selected animal and to pass through an opening in the female member so that the neck of said stem will engage in said opening.
when the male and female members are fastened together there is a spacing between them which is greater than the thickness of the ear of the animal to which the

tag is attached, so as to permit circulation of a
198938
The applicator has a stud or pin to engage in the hollow stem, the inner end of the shank of the head being engageable with the outer end of that stud or pin.
It is preferred that the pointed head have, at about the middle of its shank, a shoulder to bear upon an internal shoulder in the hollow stem of the male member so as to firmly hold the pointed head in position. It is also preferred that the tapered outer 10 end part of the head be made with a peripheral groove or recess which
198938
will provide a cutting edge operable when the pointed head is pressed through an ear of an animal to co-operate with a shoulder of the female member and cut an opening in the ear.
The pointed head is preferably made of metal - such as brass - and the female member and remainder of the male member may be made of a resilient or flexible plastics material, such as polyurethane or polyethylene.
In order that the invention may be readily understood and conveniently put into practical form reference will now be made to the attached illustrative drawings, wherein:
Fig. 1 is a plan view of the male tag made according to this invention;
Fig. 2 shows a side elevation of the male tag;
Fig. 3 is a view in cross-section on the line and in the direction of the arrows 3-3 of Fig. 1;
Fig. 4 shows the pointed head member on enlarged scale; Fig. 5 illustrates in plan view one design of female tag member; and
Fig. 6 is a transverse cross-section on the line and in the direction of the arrows 6-6 of Fig. 5«
The male tag member has a base part 11 which, as shown, is substantially circular in shape and has a stem 12 extending substantially normal to it from a central location. At the outer end of the stem 12 there is a neck 13 of reduced external diameter, providing a shoulder 14. Extending through the stem 12 and base II is a co-axial opening or passageway 15 which is
_£C

198938
• io
shouldered at 16 so that the outer end part 17 thereof is of reduced diameter.
Mounted in the outer portion of the stem 12 is the pointed head member having a head 18 and a co-axial shank 19, the shank 19 being of a diameter to fit tightly in the outer end part 17 of the passageway through the stem 12 and near its inner end it has an integral collar 20 adapted to bear upon the shoulder 16 and resist withdrawal of the pointed head member from the stem 12.
The pointed head 18 is generally of conical shape and it has a circumferential groove 21 between the pointed outer end 22 and the rim 23, forming a cutting edge 24. The rim 23 is of a diameter substantially the same as that of the major part of the stem 12, somewhat larger than the neck 13.
The female member has a flat flap 26 with a co-planar neck 27, extending normal to which is a cup 28 with a recess 29 and an opening 30. The opening 30 is a little smaller in diameter than the stem neck 13, and the recess 29 in the cup 28 is large enough to accommodate freely the pointed head 18, the depth of the recess 29 being such that the pointed outer end 22 will not project beyond the rim 31 of the cup.
The length of the opening 30 through the base of the cup 28 and neck 27 is the same as the length of the neck 13 of the stem 12 so that the pointed head 18 may be pressed through the opening 30 and into the recess 29, when the neck -13 will be gripped tightly in said opening with the base of

the neck 27 pressed against the shoulder 14. Thus, the female member will be held in spaced relationship with the base 11 of the male member, and that spacing is greater than the thickness of the animal's ear, so as to permit circulation of air across the ear.
When the pointed head 18 is being pressed through an animal's ear and into the opening 30 the cutting edge 24 of said head will co-operate with the underside of the neck 27*
which then acts in the same manner as an anvil, to cut an opening in the ear. It is believed that such an opening,
being a relatively clean cut, will heal more rapidly than will a pierced opening.
It is apparent that the pliers for applying the two parts of the ear tag to an ear of an animal may be of the same general design and adapted to operate substantially in the manner as illustrated and described in the New Zeal and Patent
Specification Nos. 162710/164351 and Australian Patent Speciiipat±e«ri_ S8S54/<bS

With this construction that is not necessary.
When the male tag member is securely engaged with the female tag member the tight engagement of the stem neck 13 in the opening 30 ensures that the material of the neck 13 engages tightly on the shank 19 of the head member, whereby to ensure retention of that head member in the male tag member and inhibit disengagement of the two parts of the tag.
The solid pointed head member may be fitted into the moulds for formation of the plastics male tag member Whereby to mould the tag member integrally with the pointed head member, or it may be applied to the moulded plastics male tag member as a subsequent operation.
It is to be understood that the shape of the base 11 of the male tag member and the flap 26 and neck 27 of the female tag member may be made any satisfactory shape to suit individual requirements and that the sizes and proportions of the two tag members may be altered as desired. All such modifications in details of design and/or construction.
