COMPLETE SPECIFICATION.
An Improved Ear-clip for Marking Stock.
I, THOMAS OLIVER TURNBULL, of Kawhia, in the Provincial District of
Auckland, in the Colony of New Zealand, Sheep Farmer, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention has for its objects marking, dating, or numbering stock such as
sheep and cattle by cheap and simple means and performing these operations with
facility and in a better and more convenient manner than heretofore.
In order that my invention may be most easily understood I will now proceed to
describe the same and for that purpose shall refer to the accompanying sheet of
drawings.
Fig. 1, is an enlarged view shewing the upper part of my improved ear-clip for
marking stock.
Fig. 2, is a similar view in section shewing the lower part of my improved ear-
clip for marking stock with fixed center pin.
Fig. 3, is a similar view in section shewing the lower part of my improved ear-
clip with loose center pin.
Fig. 4, is a similar view in section shewing my improved ear-clip as in use.
a, b, & g, are circular plates made by preference of tinned iron or other suitable
metal or material which is flexible and not easily acted upon by the weather.
These plates are dished or made slightly concave as shewn for strength and by
presenting a rounded surface externally are less liable to be entangled by grass or
similar objects. They may be painted or enamelled in any desired color. I prefer
to make them circular in shape as shewn on the drawing and of a size large
enough to conveniently allow of marks, dates, or numbers being printed or stamped
thereon.
Fig. 1, shews the upper plate a, which is provided with a hole as shewn of a
diameter equal to the reduced portion of the shank of the pin or stud c, (Fig. 3)
and h, (Fig. 2), and is split or cut as shewn at d, for a purpose to be hereinafter
described. Fig. 2, shews the lower plate, which is provided with a pin or stud h,
having a pointed head k. This pin or stud is made either fixed to or solid with the
circular plate g. Fig. 3, shews an alternative form of the lower part of my ear-
clip in which the lower plate b, is perforated with a hole of a diameter large
enough to allow the pointed stud or pin c, to pass through the same. This pin or
stud is provided with a head f, slightly larger in diameter than the hole in the
plate b, and is also provided with a groove near the point capable of receiving the
upper plate a, (Fig. 1). Fig. 4, shews the upper plate in position on the stud or
pin c, as in use, and also shews an alternative form of the stud or pin c, and lower
plate b.
The method of attaching my ear-clip is as follows:-The ear of the animal to be
marked is punctured by the pointed head e, and the pin or stud c, (Fig. 4) which is
made of a length suitable for this purpose, inserted, and afterwards passed through
the hole in the plate a, the slits or cuts d, around the said hole allowing this to be
done with facility. The metal in the plate a, displaced by this operation is then
pressed back into its former position and being now underneath the head e, and
fitting in the groove in the stud c, firmly and safely secures the same and provides a
neat and simple ear-clip for marking stock.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is,
1. The combination with a plate such as g, (Fig. 2) having a pin or stud such
ash, either fixed to or solid with the said plate g, and having a reduced part and
pointed head k, of a perforated plate such as a, (Figs. 1 & 4) having slits or cuts
such as d, substantially as described herein and illustrated in the accompanying
drawing.
2. The combination with a plate such as b, (Fig. 4) having a pin or stud such
as c, either fixed to or solid with the said plate b, and having a groove near the
point, and pointed head e, of a perforated plate such as a, (Figs. 1 & 4) having slits
or cuts such as d, substantially as described herein and illustrated on the accom-
panying drawing.
3. The combination with a perforated plate such as 6, (Fig. 3) and a perforated
plate such as a, (Figs. 1 & 4) provided with slits or cuts such as d, of a grooved
pin such as c, (Fig. 3) having a head such as f, and pointed head such as e, sub-
stantially as described herein and illustrated on the accompanying drawing.
4. The perforated plate a, (Figs. 1 & 4) having slits or cuts such as d, sub-
stantially as shewn and for the purpose specified.
