COMPLETE SPECIFICATION.
A Double Knob or Button for Distinguishing Domestic and other
Animals.
I, WALTHER KUWERT, Altenfelde b/Tapiau in East Prussia, 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 :-
This invention relates to a double knob or button, made of celluloid, to be used
as a mark for distinguishing domestic and other animals. The button is fixed to
one of the animal's ears.
And in order that my said invention may be properly understood I have hereunto
annexed an explanatory sheet of drawings whereon:-
Fig. 1 is a side view of one part of the button.
Fig. 2 is an underside view of the same.
Fig. 3 is a side view of the button as it appears when both parts are fitted
together.
Fig. 4 is a section of the other part of the button.
Fig. 5 is an underside view of the same.
The button consists essentially of two parts a and b, the part a being provided
with a stem or shank e, carrying at its end, a divided spring-heel-piece d which fits
into a corresponding opening in the part b. The heel piece is luted in the opening
by a mixture of absolute alcohol and ether.
A special ink is used for writing on the buttons.
It consists of 100 parts of
absolute alcohol, 3 parts of nitrate of silver, and 3 parts of nigrosine.
This ink is transferred to the celluloid by means of a sharp and hard nib which
should not be too full. The writing is weather proof and does not fade and it can
only be removed by violent mechanical means.
Instead of using ink the writing may be sunk or burned in by means of a platinum
or other suitable apparatus.
The button is fixed to the animal's ear in the following manner :-
The ear required to be marked is perforated near the centre by a pair of cutting
nippers and the stem e of the part a of the button is forced through the perforation
thus made. The part is then promptly pressed against the end of the stem and
the spring heel piece d caused to enter the hole c. Before the part b is fitted in
place a drop of the alcohol and ether mixture is dropped from a flask, into the
hole c.
The spring-heel-piece d prevents the parts moving until they have been
made one by the action of the alcohol and ether mixture.
The buttons are manufactured in various sizes to suit different animals.
The number, name, and year of birth of the animal can be written on the
front surface of the celluloid disc where it can be distinctly seen, and the
pedigree of the animal together with the residence and name of the owner on
the other side.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
consider novel and desire to claim is :-
A double knob or button, as a mark for animals, consisting of two celluloid
discs, b, designed to receive an inscription, one of which has a shanke and spring-
heel-piece d which fits into a recess c in the other part, both parts being joined

page_text: together and the joint luted with a mixture composed of equal parts of alcohol
and ether, substantially as hereinbefore described with reference to the drawings
annexed.
Dated this 30th day of January 1894.
