Tidenden," Copenhagen, Denmark, for an Invention of "IMPROVEMENTS

PROVISIONAL SPECIFICATION left by the said Anthon Steenberg at the
Office of the Commissioners of Patents on the 22nd November 1881.

AND SHOES." [A communication from Albert Hansen Christensen and Gustav
Lund, of Oröskjöbing, Denmark.]
This Invention consists in making the bottom part of the heel movable, so that
it may be easily turned round when worn on one side. without removing it from
its connection with the upper part of the heel. This is effected in the following
manner: To the upper or fixed part of the heel a disc having a boss on its
underside is secured, and into this boss the square head of a screwed pin is
fixed. To the upper side of the disc a spring is rivetted, a notch being made in
the front part of the heel to give free scope to the motion of the spring.
To the bottom part of the heel another disc is secured, and in the middle of the
disc is a round hole corresponding to the boss on the upper disc, which acts as the
centre on which the lower disc turns. A small round disc having a square hole is
inserted between the leather of the bottom part of the beel and the lower disc, the
square hole fitting over the square bead of the screwed pin. The two parts of the
heel are connected together by means of a nut, the two top layers of the leather
forming the lower heel being made with a hole to allow of the nut being
screwed on.
The lower portion of the heel thus far prepared is then secured to the upper part,
the nut being screwed on so that while being secure the lower heel will be free to
turn round as required. The remaining layers of leather to complete the lower
portion of the heel are then pegged on. In order to prevent the heel turning round
when not required the spring is provided with a pin, which takes through holes
formed in both the upper and lower discs to receive it.

ANTHON STEENBERG, Patent Agent, Editor of the "Industri Tidenden,"
Copenhagen, Denmark. "IMPROVEMENTS IN MECHANICAL HEELS FOR BOOTS 5
AND SHOES." A communication from Albert Hansen Christensen and Gustav
Lund, of Aroskjöbing, in Denmark,
This Invention consists in making the bottom parts of the heels of boots and
shoes moveable, and so connecting them with the upper parts that they may be
easily turned round when worn on one side without the necessity for removing 1
them from their connection with the upper parts of the heels.
In the accompanying Drawing, Fig. 1 is a sectional view of a boot heel
constructed according to this Invention, shewing the different parts in position and
the remaining Figures shewing the various parts in detail.
A is the upper or fixed portion of the heel, and B the lower or moveable portion 1
of the same. To the upper part A a disc a is secured by screws, and in the centre
of this disc a and on the underside thereof is a boss b¹, to which a screwed pin c
having a square head is secured in any convenient manner, see Fig. 2. 'Onto the
upper side of the disc a spring d is rivetted (see Fig. 3), and to give free scope to
the movement of this spring a notch g is made in the front of the heel, as seen 2
in Fig. 1. The spring d alone is seen at Fig. 4.
To the bottom part of the heel B a disc b is secured by screws. In the centre of
this disc b is a round hole (see Fig. 5) corresponding in diameter to the boss b' on
the underside of the disc a.
When the two discs a and b are placed together the boss b¹ enters the hole in 2
disc b and forms a centre on which the disc b can turn.
m is a small round disc with a square hole n in the centre (see Fig. 6), and this
disc is inserted, as shewn in Fig. 1, between the leather of the lower part B of the
heel and the disc b. The square head of the screw c projects into the square hole n
of the disc m. The bottom part B of the heel is connected to the upper part A. by 3
means of a nut p, which is screwed onto the screwed pin c, a recess q being formed
in the part B to receive it.
The part B is connected to the part A before the layers of leather marked 1, 2, 3,
are fixed onto the part B. The nut is first screwed up, so as to allow of the bottom
part B of the heel being turned round when required, and the layers 1, 2, 3, are 3
then pegged on. In order to prevent the part B turning round when not required
the spring d is provided with a fixed pin e, which projects through a hole in the
disc a and enters corresponding holes in the disc b.
The number of holes r, shewn in the Drawing at Fig. 5, is four, and consequently
the moveable part of the heel can be fixed in four different positions, but the
number of holes is not limited.
Having now described the nature of this Invention for "Improvements in
Mechanical Heels for Boots and Shoes," as communicated to me, and explained the
manner of carrying the same into effect, I claim,—
In a boot heel formed in two parts, as A and B, the means, substantially as 4
herein shown and described, for connecting the said parts together, so that as

page_text: the heel becomes worn on one side the lower part may be easily turned round to
present a new wearing surface without removing it from the boot or shoe.
In witness whereof, I, the said Anthon Steenberg, have hereunto set my
hand and seal, the Eleventh day of May, in the year of our Lord One
thousand eight hundred and eighty two.
