COMPLETE SPECIFICATION.
Improvements in and connected with Spurs.
I, GUSTAV KÜHN of 4, Promenaden Strasse Gmuend Suabia, Manufacturer,
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:-
The removable spurs hitherto known have the drawback that they are too
complicated in construction and consequently are too costly so that in practical use
they have found little or no success. A great want is still felt for spurs of simple
construction easily affixed and equally easily detachable from the heel. This
requirement is supplied by the spur adjustment which I have invented and which is
constructed on the most simple method possible and in such a manner that it can be
fixed in place without any special apparatus and without any great exertion. For
this purpose slots in the sides of the arms of the spur are brought into connection
with catches forming part of a spring holder placed in the heel of the hoot in such
a manner that the spur when in use presses firmly against the end part of the heel.
The accompanying drawing shows my improved arrangement as follows:-
Figure 1 illustrates a view from below of a heel with the spur in position.
Figure 2 is a side elevation of the same.
Figure 3 shows a plan after the removal of the heel plate, the projecting plate
and the
spur itself.
Figure 4 shows a section on the lines xx of Figure 1 after removal of the spur.
Figure 5 shows a view from behind and
Figure 6 shows the method of securing the spur whilst Figures 7 to 10 show
details of the mechanism.
The heel consists of two parts ab secured together, of which the upper part a
serves for the reception of the locking apparatus for the spur c and is provided with
a rim a which prevents any movement of the spur in an upward direction whilst
the end part 6 bears behind a projection d which prevents any movement of the
spur downwards.
The locking device which is clearly shown in Figure 4 is located in an aperture
formed in the upper part a, consists essentially of a rectangular box e Figure 7 in
which the bar provided with projections 12 is placed. The latter is normally
pressed forwards by means of a spring g Figure 3 and is provided with two points f
with which the arms of the spur engage. For this purpose the said points flare
formed somewhat hook shaped as shown in Figures 3 and 9 whilst the arms of the
spur possess recessed grooves c' Figures 10 to 10ª.
In order to prevent dust or dirt from entering the box e the same is protected
and enclosed by means of a shutter h Figures 4 and 8. In order to secure a correct
adjustment of the latter upon the box e the same is provided with guides e¹ which
engage in the grooves of the shutter.
The above described parts having been secured into the heel of the boot in the
proper manner the bar is pressed against the box to the right by means of the
spring g Figure 3.
When it is required to affix the spur, this is effected in the manner specially
shown at Figure 6, that is to say the points f' are pushed into the recesses c¹ of the
arms of the spur after which the spur is turned upwards and at the same time
pressed to the left Figure 6 and drawn forwards so that it comes to rest above the
projection d. This baving been accomplished the spur is drawn to the right by

page_text: means of the pressure of the spring a consequently is pressed firmly against the
hinder part of the heel whereby the slipping or working loose of the same is
entirely prevented.
It would be clear from the above that the insertion of the spur can be
accomplished easily and simply whilst the removal thereof can take place equally
easily.
The spur of my invention has the great advantage that whilst being so easily
adjusted to the heel it can in consequence of its simplicity be quite as cheaply
manufaatuund on the num
CLAIM.
Spur with spring holding device characterised by having a retaining bar f con-
trolled by a spring which is placed movably in a box e let into the heel and provided
with points or projections with which the arms of the spur engage in such a
manner that upon drawing the said spurs forwards and upwards over a projection d
forming part of the heel the said spur is held firmly pressed against the hinder part
of the heel.
