Improvements in Leather Shaping Apparatus or Machines for use
in the Manufacture of Boots, Shoes, and the like.
A communication by JACOB ZEH, of Eglosheim, near Ludwigsburg, Wurtemburg,
in the Empire of Germany, Mechanic.
1, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 invention hereinafter described has for its object the production of a pressing
or shaping apparatus at a price which renders it attainable by any workman, and
by means of which the upper leathers for boots, shoes and the like, and especially
at those points which come in contact with the heel curve of the foot, can be pressed
or shaped, and that not only on the upper side of the heel curve but also in the
entire direction of the same towards the heel.
The invention will best be understood by aid of the accompanying sheet of
drawings on which,
Figures 1 and 2 are vertical elevations at right angles to one another, and
Figure 3 is a plan view of the apparatus, whilst
Figure 4, drawn to a larger scale, is a section through the part of the apparatus
where the pressing or shaping itself takes place.
The angularly shaped iron A is pivoted at o to the frame B which is fixed by
means of clamps to the board or table T. On the frame B, there is a framework b
in which revolves the spindle d which actuates the frame A. by means of the jointed
links e, the latter being first hung in the frout one of the two 1 shaped slits a
and a and the spindle d then turned by means of the handle k, whereupon the
iron A with the leather is drawn into the frame B. The jointed link e may, as
desired, be suspended in the second slit a', after the spindle & has been first turned
correspondingly further back, and the pressing or shaping may then be further
perfected.
The pressing or shaping itself takes place at the angle point of the frame B,
where there are three adjusting screws c, e and ce journalled into the stirrup C, by
adjusting which the pressing or shaping at the desired part may be more or less
strongly or perfectly done. The frame B consists of two parts joined together by
a spring which are provided on their inner sides with sheet zinc, or other metallic
plates, and which can be approached or receded from one another by means of
adjusting screws ccc. In order that the pressing or shaping may not alone take
place at the upper part of the heel curve but also in its continuation against the
heel, the iron A is tapered to a small degree (see Figure 4) so that the parts of
the leather lying further back from the top are also strongly pressed and drawn
through.
The position of the adjusting screws c², c², c³ is so chosen that the upper leather
is not pressed on the entire top but only in the proximity of the heel curve and in
its extension at the heel, whereas in the other positions it remains entirely
unoperated upon so that the leather is not in the least injured as is the case with
other shaping apparatus.
By making use of the spindle d, which is coupled by means of the link e with the
one end of the pressing or shaping iron A, the leather may be subjected to an
uncommonly strong pressure at the expenditure of a very little amount of
anipulation of the handle

page_text: The improved apparatus owing to its simplicity can be produced at a very low
price. The existing apparatus have only very slightly approached it in regard to
its capacity for work.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is-
..
1. A leather pressing or shaping apparatus consisting of an angularly shaped
iron A thickened at its rear, which turns on the elastic or springy half frame B,
the latter being provided on its inner side with a metallic plate, and which iron A
is coupled with a spindle d by means of a jointed link e so that on being turned by
the intermediation of a crank or other suitable turning appliance, the leather can
be brought into the frame B.
2. In a pressing or shaping apparatus of the kind described in Claim 1, and for
the purpose of treating the leather only at certain parts, the arrangement of a rigid
stirrup C taking onto the elastic or springy half of the frame B, on the one side of
which the halves of the frame can be more or less brought together by means of a
number of adjusting screws c', c², e, etcetera, so that the pressing or shaping can be
more or less strongly carried out at the part in question.
3. The application to the pressing or shaping iron A of the kind described in
Claim 1, of two or several shaped slits a al lying behind one another on the edge
opposed to the turning point into which the jointed link e may be placed in turn
so as to afford a gradual drawing in of the iron A into the frame B without
necessitating the employment of too large a spindle d.
