This invention relates to tools and devices such
as are commonly employed for the ear-marking
connected, as at E2, to provide spacedly-opposed,
relatively-longer handle portions 13 adapted for
of live stock, particularly cattle, and has as an '
spacedly-opposed, relatively-shorter jaw portions

A further object of the invention is to provide

live stock marking tool of means automatically
operable as an incident of tool manipulation to
facilitate removal of the tool from marking en

The conventional marking tool depicted by the
drawing comprises a pair of closely similar, suit
ably curved levers Ill and H formed to overlap
intermediate their ends and be pivotally inter 55
made. As conventionally constructed and com
monly used, the tool hereinabove described has
disadvantage in that the needles I 9 do not read

animal member when and as the jaw portions M
are permitted to separate, and in that the needle
points are apt, even under most careful handling,
to scratch, tear, and lacerate the animal mem
ber surface, particularly at and about the punc
tures constituting the desired pattern, with con
sequent blurring and loss of definition in the
jaw portions [4 of the tool are respectively closed
together or divergingly opened. Thus, the jaw
portions [4 being in their position of normal sep
aration, as shown in Figure l, the said yoke with
its bar 24 is held outwardly from the head I6 and
beyond the points of the needles ii] to de?ne, to
marking ultimately obtained.
