Specification Accepted, 5th Apr., 1887
I, CHARLES KNOWLES TOMLINSON, of the Firm of Tomlinson and Hayward of
Beaumont Manor, Lincoln in the County of Lincoln, Manufacturer, do hereby.
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and asceriained in and by the following statement :-
This invention relates to cattle marks or studs, and by means of numbers, or other
characters, stamped, impressed or otherwise recorded thereon, the pedigree or geneo-
logical relationship of an animal is identified; that is, the mark after having been
once attached or fastened, is an inseparable one; and upon one or both of the stud
heads of which, a number or other record is impressed or made, which refers to the
register of the strain or lineage of the animal, recorded in the stock book of the
herdsman.
Figure 1 represents in side elevation, and figure 2 in vertical section, a two part
car mark, constructed according to my invention. Figure 3 represents the same dis-
united, or before the parts are put together. Figure 4 represents a horizontal section
upon the dotted lines A B figure 1, while figure 5 shows the central stem of the one
pari, upon an enlarged scale; it also shows in section the securing tongues, or the
incans, whereby the one part is connected to the other part, and which said section is
upon the dotted lines CD figure 6, which shows in plan, a spring disc or plate pierced
about its middle, with spring tongues disposed in the direction of a diameter.
Figure 7 shows a plan of the underside of the tubular stem and base of the back part,
which is made from a cruciform blank of sheet metal. Figure 8 shows a top side
view of the tubular hollow stem of the other part of the mark, and which is made
from a cruciform blank figure 9. Figure 10 represents the inside plate of the front
part.

The same letters of reference indicate corresponding parts in the several of the
Drawing.

page_text: A is the front part, and B is the back part of the ear mark, the former of which
consists of a tubular hollow stem a, open at its top, with a flange or base a at its
bottom, all made out from a single blank of sheet metal. bis the front shell of the
body part of the mark, whose edges are turned over the outer edges of the securing
disc c, by means of which, the inside parts are enclosed and affixed in position within
the interior of the body part. d is a thick ring, or washer, and e is a spring securing
plate, pierced about its middle, and with affixing or securing tongues e, with its con-
caved inner edges presented to each other, and which said edges take within a groove
of the other part, on the parts being put together. The other or front part B consists
of a tubular stem, with a circular and divided base 2, and with an annular groove
or rut, near the end of the stem part, and which end is rounded off, to facilitate
the springing thereover of the presented tongues e², of the scuring plate.e. gis
the front shell, with its boundary edges turned over an inside disc h, between the
inside of which, and the underside of an iron disc i, the base 2 of the steni f' is firmly
secured.
In securing the mark, an animal's ear is pierced or slit in a suitable manner, and
the stem a of the part A passed therethrough. This having been done, the stem f of
the other part B, is then passed into the hollow stem a of the part A, and then pressed
home, which then becomes inseparable, or unable to be disunited.
The pressing home, causes the rounded end of the stem, to deflect inwards the
tongues e² of the plate e, and on the said tougues passing over the rounded end or
head as aforesaid, the said tongues snap and spring into the annular groove or
rut 3, and thereby secure the two parts A and B together, as hest seen in Figures 2,
4 and 5.
Although I have described that A is the front part, and B the back part, yet this is
immaterial, as A may be the back, and B the front.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is.-
First. A cattle mark, consisting of two parts, in which the stem carried by one
part, takes into a hollow or tubular stem carried by the other part; and which said
parts, are made inseparable, or not to be again parted, by a spring tongue, or spring
tongues, free ended catches, or their mechanical equivalents, carried by, or contained
within the one part; taking into or engaging with an annular groove, or engaging ai
the back of a shoulder or shoulders, (annular or otherwise) on, or carried by the stem
of the other part, and which said parts are constructed substantially in the manner as
herein described and illustrated.
Secondly. In a two part, cattle mark, or stud, as herein described and set forth in
the several figures of the drawing, consisting of the part A, with a siem a, back,
front disc c, washer d, and spring plate e, (with its free tongues or catches e²) inter-
posed between the underside of the base a² of the hollow stem a, and the ring d,
while the part B consists of a stem f, annular groove f³, base, front, and washer i,
interposed between the base of the stem, and the front shell aforesaid; and which
said parts are constructed and arranged, as described and set forth.
Thirdly. Making or forming the stem a, and its base a², of the one part, and the
stem, and its base of the other part, from a cruciform blank, substantially as
described and set forth in figure 9.
