IMPROVEMENTS IN MACHINERY FOR SHAVING SKINS FOR LEATHER MAKING
Year: 1878

page_text: LETTERS PATENT to Désiré Carpentier, Manufacturer, of the City of Paris, in
the Republic of France, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR SHAVING SKINS FOR LEATHER MAKING."
Sealed the 13th December 1878, and dated the 24th June 1878.
PROVISIONAL SPECIFICATION left by the said Désiré Carpentier at the
Office of the Commissioners of Patents on the 24th June 1878.
DÉSIRÉ CARPENTIER, Manufacturer, of the City of Paris, in the Republic of
France. "IMPROVEMENTS IN MACHINERY FOR SHAVING SKINS FOR LEATHER
MAKING."
This machine consists of two uprights connected by a table below and cross bar
above on which a frame oscillates, having at its lower end two traverses furnished
with bronze blades, and between which the shaver or cutting tool moves.
In cases where a beam or girder is at disposal the frame may be fixed thereto,
and so dispense with the uprights.
The upper surface of the table is a cylinder whose axis is the cross bar; this face
is covered with zinc and receives the skin.
The knife or shaver, properly so called, is a rectangular box of bronze having
ears, and capable of sliding between the traverses. In this box is a plate oscillating
on screws maintained vertically. On the plate is attached the support of the
shaving or cutting blade, capable of sliding on it wherever directed and maintained
by guides; this cutting tool support can ascend or descend by means of a regulating
screw.
The skin is held by nippers; the skin being spread on the table the workinan
oscillates the frame, changing the position of the shaving tool each time; then the
Pas GIL

page_text: blade takes off a shaving, more or less thick, according to the height the blade is
from the skin, which is regulated by the scrow.
In returning the plate turns on the screw, so that the knife only brushes the
skin. The blade only projects slightly from its holder, so that it is prevented
cutting too deeply. The skin nipper is formed of a movable bar actuated by levers
admitting of griping the skin between this bar and the table.
By replacing the knife with a glass whose edges are rounded the apparatus may
be used for polishing leather.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Désiré Carpentier in the Great Seal Patent Office on the 21st December
1878.
DÉSIRÉ CARPENTIER, Manufacturer, of the City of Paris, in the Republic of
France. "IMPROVEMENTS IN MACHINERY FOR SHAVING SKINS FOR LEATHER
MAKING."
This Invention relates to apparatus for shaving skins, and consists of the
following parts shown in the accompanying Drawings, of which Fig. 1 represents
an elevation of the machine; Fig. 2, a section at X, Y, of Fig. 1; Fig. 3, an
enlarged and detailed view of the shaver and its regulator; and Fig. 4, a section
at P, Q, of Fig. 3.
A, A, are two frames united by a table H and cross bar C, C, on which a frame B
oscillates, bearing at its lower end two traverses E, F, furnished with bronze
blades; it is between these blades that the shaver moves. Where a beam is
at disposal the frame B may thereto be connected, and so do away with the
uprights A, A.
The upper surface of the table H is a cylinder whose axis is at C, C, and this
face is covered with zinc, which receives the skin.
The shaver, properly so called, is a rectangular box of bronze having ears, and
capable of sliding between the traverses E, F. In this box is a plate K turning
or oscillating on screws o, held vertically. On the plate K is mounted the blade
support J, sliding at will thereon, and maintained by guides; this blade support J
can ascend or descend by means of the regulating screw L. Finally, on the blade
support is fixed the blade I, which is the working part of the machine.
The action of the machine is as follows:-One end of the skin is fixed between
the jaws of the skin nipper U; the skin being spread on the table the workman
oscillates the frame B, changing the position of the tool each time; then the blade I
takes off a shaving, more or less thick, according to the height of the blade, which
is regulated by the screw L; in the return stroke the plate K turns on the screws O
in such a manner that the blade only rubs on the skin. The blade only projects a
little beyond the blade support, whose tail prevents the blade cutting too deep.

page_text: The skin nipper is formed of a movable bar U manoeuvred by a system of levers
allowing of locking the skin between the bar and the table; in fine, the machine is
equally applicable for shaving in tannery, for hollowing tanned skins, and also for
polishing leather; in this latter case the blade is replaced by a glass with rounded
edges.
"
R is a cross bar support of the skin nipper U; S, handle of the opening lever S¹;
S", transverse guide; S, coupling; R, axis of the opening lever; T, shaft of the
skin nipper; t, upright of the latter; x, stop lath of the skin nipper.
In witness whereof, 1, the said Désiré Carpentier, have hereunto set my hand
and seal, this Nineteenth day of December, in the year of our Lord One
thousand eight hundred and seventy-eight.
