page_text: Cutting, Splitting, Paring, and Skiving Leather.
I CARL HERRMANN RAEB of 32" Charlotten Strasse Berlin, in the Empire of
Germany, Shoe-Manufacturer, do hereby declare the nature of this invention and in
what manner tho samo is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention is designed to supply a better and quicker mode of cutting splitting
paring skiving strips of leather such as welts stiffenings runners small straps and
other pieces much used by Shoemakers and also of paring the edges of boots
and Shoes.
These various operations are now usually effected by cutting from the plain leather
by means of the ordinary Shoe knife a work which is not only tedious and fatiguing
in itself but which demands great skill to accomplish satisfactorily.
My improved instrument consists of one or more broad blades, chiefly straight, but
some of which may be bent or curved at one side, one of which blades is so attached
to a metal frame with a handle that it can be moved forward or backwards on a fixed
pin working in a slot in the blade, and can also be elevated or depressed; and it is
furnished with a guide-hook two movable guide cheeks, an adjustable fork, an adjust-
able bridge, a bottom plate, several separate adjustable fence or guide plates, and
several set screws and thumb screws, so as to adapt it for a great variety of work.
I will now proceed to describe it in reference to the accompanying drawings.

constrained thereto by the hook F while the guiding-cheek b, on the other side of y
presses always against the upper side of the leather and closes up the seam of
the boot.
Corresponding to the desired width of the remaining edge of the leather the guide-
check b, is set high or low by means of screws. Through the simple form of the tool
curves are cut as easily as straight edges, any desired strip is removed and the edge
is uniformly pared.
Finally by means of the small taper fork G as shown in Fig. 14-16, the tool can
be used to cut small straps. To effect this the fork G can be attached to the guide-
hook F by removing the plate E from the pin before named, (Figs. 4 and 5), and as
in the previous case, the separated strips of leather are drawn backwards and upwards
in a similar way through the opening ².
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 :-
1st. A cutting instrument for splitting paring trimming or skiving leather consisting
of changeable adjustable blades fastened by means of a set screw to a metal frame,
which is furnished with a bridge, guide-checks, guide-plates, a guide-hook, bottom
plate, set screws, thumb screws and a special form of fork, as herein described and
set forth.
2nd. An instrument for Shoemakers and like uses, capable of being adjusted for
paring boot-sole edges, cutting small straps, splitting and skiving leather as herein
described and set forth.
3rd. A cutting tool for various kinds of cutting work connected with Shoemaking
comprising the blade attached to the ground-plate B, in combination with the
bridge D, the guide-cheek b, the plates E, the guiding-hook F, the fork G, and the
necessary adjusting screws, as herein described and set forth.
