Improvements in Spurs.
I, JOSEF OSTER, of 17 Brietestrasse, Bonn, in the Empire of Germany, Judge's
Assessor, 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 relates to spurs, the object being to so construct them that they
can be taken to pieces.
For this purpose the heel-piece of the spur is composed of two branches jointed
or hinged together, the arm which carries the rowel, with its central spike, being
adapted to be unscrewed from the heel-piece and, when screwed into it, fixes the
two branches together and prevents them moving.
In the accompanying drawing,
Figure 1 is a plan of a spur constructed according to my invention, the parts
oeing shewn fastened together:
Figure 2 is a detached side view of the rowel-carrier and its central spike:
Figure 3 is a plan of the heel-piece; and,
Figure 4 is a rear view of the joint or connection of the branches of the
heel-piece.
The two branches 6 and 6' of the heel-piece are united together by means of a
joint, the branch being, for this purpose, forked at g; into this fork g the end f
of the other branch is so secured as to turn upon the pin d. The form of this
joint is such that the branches can only be moved towards one another to the
extent shewn in Figure 1. The end of the arm 6, which end is curved or cut
obliquely at f, then comes in contact with a correspondingly shaped curved or
oblique surface formed between the arms of the fork g on the branch b. A.
screw-threaded hole is made in the end of the branch b, into which hole the
carrier a of the rowel is screwed. For this purpose the end e of the rowel-carrier
which comes against the heel is constructed with a screw terminating in a point
which serves as a central spike. In order that the carrier a after it has been
screwed in may hold the two branches of the heel-piece firmly together, it is
provided, at the point where the screw begins, with a shoulder, the flat surface of
which is then closely applied to the two outer surfaces of the halves of the joint
which are made flat.
A spur of this construction is applied to a boot-heel in the following manner :-
The heel-piece, from which the rowel-carrier has been first removed, is opened,
placed over the heel and closed upon it, the lateral spikes k fixed on the free ends
of the branches being pressed into the heel.
The rowel-carrier a is then screwed into the hole of the arm b until the stop e
of the carrier a is in close contact with the two halves of the joint. By this
means the pointed end of the screw c which forms the central spike is driven into
the heel which is represented by a dotted line in Figure 1, so that the spur is
firmly attached to the heel. The spur is removed from the boot-heel by a reverse
series of actions.
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
--
1. A spur having its heel-piece constructed of two parts or branches jointed
together, so that they can be opened outwards or brought towards one another,
and a rowel-carrier provided with a spike adapted to be screwed into one of the
branches of the heel-piece and to enter the boot-heel, thereby preventing the

page_text: heel-piece from opening and keeping the spur firmly connected to the heel,
substantially as hereinbefore described.
2. The improved spur herein before described and illustrated in the accompanying
drawing.
