Detachable and Fastenings.
I, SEBASTIAN KISTLER, of Adl. Medenau, in the Empire of Germany, Manu-
facturer, 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 an arrangement for quickly and easily changing or
renewing the wearing surfaces of the soles and heels of boots and shoes, in which
the parts are more durably connected than has hitherto been possible even when
the wearing surfaces of the soles and heels have been permanently connected by
iron or wooden nails.
The disadvantages of this latter and still the most usual method bave frequently
led to the manufacture of various forms of detachable fastenings and a great
number of such constructions have been tried. They however all suffer from the
evil that although detachable a durable union between the detachably connected
parts is not obtained and for the following reasons.
The various forms of fastening have been adapted for holding together the
abutting surfaces of the parts composing the soles and heels but it has been
overlooked that it is less the surfaces than the edges of the parts to be connected
that require holding together as is evidenced by the usual method of soleing in
which the nails are placed not so much in the middle of the soles and heels but
chiefly at their edges.
Even when the wearing. surfaces of the soles and heels have been thus
permanently attached they frequently become loose because in walking the foot
strikes sometimes against blunt and sometimes against pointed objects the former
breaking the nails, the latter working into the dividing slit above the wearing
surface of the sole or heel and tending to detach it. If this takes place when a
permanent nailed connection is used it will take place still more when a detachable
connection is used which will naturally be acted upon more easily by pressure and
blows against outside objects.
In order to make a serviceable detachable connection it is necessary to avoid any
slit or opening between the connected parts and as it were to incorporate the
detachable part along its whole edge with the inner portion which forms a
permanent part of the shoe. This may advantageously be done by providing the
outer sole a or outer heel 6 Figure 1 with a projecting clip a 6 all around its edge
this clip piece may be of elastic material such as rubber or flexible material such as
leather drawn inwards by an elastic cord around its edge.
A shoe sewn with a projecting welt is preferably so altered as to form a project-
ing edge c not only in front and at the sides of the sole but also at the end towards
the heel.
The clip a clips over the welt or projecting edge and springs into the angle d.
In a similar manner a recess f is provided in the upper part of the heel for the
elastic clip b¹ of the outer heel to catch into. By this means the dividing slits g or h
are wholly covered and protected even from the entrance of moisture. Above all
however outside objects cannot penetrate into the dividing slits and there have a

page_text: separating action, for the soles and heels although double are outwardly only single
pieces.
If it be wished to change the sole, this can easily be done by first drawing down
the clip a¹, and then loosening the connecting buttons i.
At the heel the metal wedge shaped head k takes the place of these buttons.
This head and the outer heel b to which it is secured may be drawn sidewise away
from the upper portion e, after in this case also first turning down the elastic
clip b¹.
Figure 2 shows a partial section of another arrangement for utilizing the com-
pression buttons at the same time as sole protectors.
Figure 3 shows an underside view of a sole so constructed.
Figure 4 shows on a larger scale and partly in section one of the clamping
buttons.
In this case the upper portion of the compression button or fastening (see
Figure 4) is fastened to the inner sole l. It has a hole or eye formed through it for
the ball shaped head of the under portion 2 of the fastening to be passed through
-the ball shaped head is slotted down the middle for the purpose of rendering
spring like whilst the stem of the under portion passes through the outer sole a
and is here flattened to a broad head 23. The portion of 2 which serves as a stem or
shank is coned outwards the stouter end carrying the broad head so as to give a
good hold on the ground. The connection of the two soles is effected by pushing
the ball shaped head of the under portion 2 through the hole in the upper portion 2¹
when it is held by reason of the fact that this head is of greater diameter than
the hole and can only be forced through the latter by reason of its being slotted.
In this way not only is a very powerful hold obtained for the buttons, but also
at the same time an effect is obtained which otherwise could only be obtained by
specially putting in separate sole protecting nails. Such nails are easily lost
whereas this is impossible with the heads ³ as they remain firmly attached to the
buttons.
The arrangements above described are distinguished by great simplicity and are
cheaply manufactured. The changing of the soles and heels may be effected in the
shortest time. They can even be put together more quickly than by nailing; and
the passage of water between the soles is effectually prevented.
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 I
claim is
1. Fastenings for detachable soles and heels, characterized by the detachable
sole or heel being formed with a clip of elastic material to grip over the edge of the
inner sole or inner heel, in such a manner that the dividing slit between the parts is
covered and the passage of outside objects into the slit prevented.
2. The clamping buttons i, the upper portion i¹ of which is carried by the inner
sole, whilst the under portion 2 passes through the outer detachable sole a, and is
here flattened to a head i³.
3. The clamping buttons i having the parts 2 which pass through the outer
detachable sole a made conical for the purpose of giving sufficient hold upon the
detachable sole a.
4. Fastenings for detachable soles and heels arranged substantially as herein-
before described and illustrated in the drawings annexed.
