Polishing Hides and Skins.
We MARIUS MARTIN and VICTOR MARTIN of the city of Paris, in the Republic of
France, and ERNEST SCHLOESSER WILLIAM SCHLOESSER and FERDINAND SCHLOESSER
of 45, Saint Thomas Street, London, Leather Merchants do hereby declare the nature
of the said invention for IMPROVEMENTS IN APPARATUS FOR SHAVING, OR SCRAPING,
DRESSING, AND POLISHING, HIDES AND SKINS, and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement:
The object of this invention is to perform various operations necessary in the
preparation of skins for tanning, and also in dressing them, such operations consisting
in shaving, or scraping, the skins and smoothing or pressing them, with steam, or gas
heated cylinders, such operations being performed on skins either in a wet or dry
state.
The apparatus employed for effecting this is of C form, and by the removal of
some of its parts, and the substitution of others therefor, the various operations are
inore effectively carried out.
.. Figs., 1, and 2, represent a front, and side view, of an apparatus of the description
embodying my invention.
Fig. 4, is a side view of the same, some of the parts being removed, and others
substituted in their place, in accordance with the operation required to be performed.
In this case it is provided with a table A, capable of a backward and forward motion,
on which two other tables T', T", are mounted.
Fig. 3, is a transverse section of Fig. 4, taken at the line A, B.
Fig. 5, is a plan showing the sliding table A, a part of the machine being a

page_text: With reference to Figs. 1 and 2.-S. and D are two revolving cylinders, the lower
one D can be raised or lowered by aid of the foot pedal P, and cranked lever P¹, to
bring it more or less near the cylinder S, to accommodate the thickness of the skins
under operation.
Having raised it as required it is then secured in position by aid of a pressure
regulator Rou the support R. This regulator comprises two bevil pinions R
Ra flywheel R and screw working up and down in the centre of the wheel R².
On turning the flywheel R this screw rises or descends as desired, the lower end
pressing more or less on the pedal P, which communicates its motion to the cranked
lever P, and so to the lower cylinder D, or to the table, for keeping it in the required
position in accordance with the amount of pressure desired to be produced.
The cylinder S, is or may be furnished either with sharp spiral blades, running
from right to left, or helical blades on one side only, very sloping to produce the best
cutting effect, for shaving the skins, or it may be covered with emery cloth for
scraping or rasping them, or it may be perfectly smooth for ironing or hot-pressing
the skins, in this latter case it is heated internally with gas or steam or some
equivalent.
The skin is placed on the table T, so that the operator can move it about as required
by turning the table with the hand.
In Fig. 4, the supports K shown in Figs. 1 and 2 are removed as well as the
cylinder D, and in lieu thereof a table A, is substituted, worked by hand as already
mentioned, and capable of sliding backwards and forwards, and raised to the
cylinder S by means of the pedal P and its accessories already mentioned, and
balanced by the counterpoise C.
On this table two others T T running on rollers are mounted. The skins to be
operated on are placed on the upper table T. On this cylinder S and in front of
the cutting blades (above which latter they slightly rise) are non cutting blades of
india rubber, or other flexible matter, serving to spread the skins out, before the
shaving takes place.
The pressure regulator R¹, mounted above the lever of the pedal by aid of its
auxiliaries, admits of the instantaneous separation, either of the cylinders S. D,
Fig. 2, or of the cylinder S and table T" of Fig. 4, so that the skins are operated on
equally throughout all their irregularities.
This regulation is necessary on account of the varying thickness of the skins..
The operator can by this method of regulation, finish the work without any
inconvenience, either by the use of the sliding table A, or the rotating cylinders D. S.
According to the operation to be performed a cylinder or other device inay be
employed, covered with india rubber, brushes, stuff of some kind, or other supple
material, which can be either fixed, or movable, for keeping the cylinder D, clear and
clean whilst in use.
A fan or blower, can be used driven by the machine, furnished with an air conduit,
striking on the skin, so as to keep the latter, from rising against the upper cylinder S,
whilst the skin is being moved about.
In smoothing skins, especially calf, and sheep skins, to make them supple, and
glossy, they are ironed, with the cylinder S, heated internally, with gas, or steam, in
this case the cylinder is smooth.
Having now particularly described, and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1st. In skin preparing, and dressing machines, two rotating cylinders S, D, brought
more or less together, by aid of the pedal P, and cranked fever, the pressure of the
lower cylinder D, on the upper one S being effected by aid of the pressure regulator R¹,
on the support R.
2nd. Covering the upper cylinder S, with emery cloth, or furnishing it with spiral
cutting blades, running from right to left, or one side only very sloped, for being as
effective as possible in shaving.

page_text: 3rd. In machinery of the description herein referred to, a lower table A, capable
of a backward and forward motion, balanced by a counterweight C, and raised or
lowered by the pedal P, in conjunction with the tables T, T" running on rollers.
4th. In apparatus as herein described, the employment of a cylinder, or other
device, covered with brushes, cloth, or other flexible matter, for pressing against, and
clearing, or keeping clean the lower cylinder D.
5th. Before the cutting blades on the cylinder S, non cutting blades of india rubber,
or other flexible substance, serving to spread the skins out, on the table, before the
shaving commences.
6th. In machinery for dressing skins, a hollow cylinder, heated internally with
gas, or steam, for pressing, smoothing, and giving a gloss to them.
