Improvements in Machines for Dressing or Finishing Skins and
Hides.
I, OTTO STEGMEYER, of 145, Wilmersdorferstrasse, Charlottenburg, near Berlin,
in the German Empire, Machine Constructor, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in machines for dressing or finishing
skins and hides.
In machines as hitherto manufactured for the smoothing, polishing, etc., of
skins and hides the latter are fed between rollers by means of a vertical plate which
moves up and down and which for changing the motion must be fitted with com-
plicated mechanism and the skin or hide to be dressed or treated is hung over the
upper edge of this plate. The disadvantages of such an arrangement consist in
the great loss of time and in the rapid wear of the working parts of the machine
due to the constant change in the direction of the motion and to the consequent
necessity for the frequent application of the brake.
Now it is the object of this invention to obviate these disadvantages and to this
end I arrange that the plates, which enable the skins or hides to be placed upon,
and removed from, them whilst the machine is in operation, are kept in constant
movement and are caused to pass between the rollers from below upwards by means
of suitably guided endless chains.
In carrying out my invention I actuate the two endless chains, which as they
move upwards are caused to pass between brushing rollers and smoothing rollers
placed above the same by means of four chain wheels arranged in each standard or
support of the machine. The plates which carry the skins, and which are sus-
pended freely to the chains by pins are provided with an elastic covering and at
their lower ends with guide strips or pins which are just long enough to enable
them to pass between the chains. The chains are kept in constant movement
during the treatment of the skins, and at the same time the plates pass slowly
between the two pairs of rollers for spreading, smoothing and compressing the
skins or hides. The machine is operated through the medium of a pulley on a
shaft having toothed wheels which drive wheels on a second shaft on which are
mounted the uppermost chain wheels, by means of fast and loose pulleys on a main
shaft which drives one of the pair of smoothing rollers at a slow speed by means
of gear wheels. This roller slowly drives the other roller of the pair by means of
gear wheels on the axles of the rollers and a pulley on the axle of the first roller
drives, by means of a crossed belt, the pulley driving the chains. Another pulley
on the driving shaft causes the brushing rollers to rotate at a high speed by means
of open and crossed belts.
Notches or recesses are made in the inner sides of the standards or supports of
the machine, one set of the said recesses allowing only the endless chains with the

behind the rollers, guides the guide strips as the plates move downwards.
The skins or hides are laid upon the plates as the latter pass from the front
notches or recesses in the supports to the lowermost chain wheels placed under the
outer brushing roller, which is enclosed on the under side by a protective plate.
When the pins of a plate have passed over the lowermost chain wheel the plate
will, after its guide strips have passed the front recesses in the frame, be drawn up
between the two pairs of rollers and the skin or hide will be brushed by the brush-
ing rollers and spread and pressed by the metal rollers.
As it passes from the upper chain-wheels to the lower chain-wheels arranged at
the back of the machine the skin or hide is, on account of the inclined position
the plate is caused to take by the guides at the rear of the supports, set free
from the outer side of the plate and when it reaches the lower rear chain-wheels
it is laid either automatically or by a workman on a block,
The front metal rollers are mounted on bent levers and are suitably weighted
with movable or adjustable weights. Adjusting screws prevent the rollers, from
striking one another after the plates have passed between them.
The skins or hides can be laid on the plates and those which have been treated
can be removed from the plates without stopping the machine.
In a slightly modified form of the machine I only employ two chain-wheels for
each chain and in this case the skins or hides are placed upon, and removed from,
the plates as the latter pass from the upper to the lower chain wheels.

I, OTTO STEGMEYER, of 145, Wilmersdorferstrasse, Charlottenburg, near Berlin,
in the German Empire, Machine Constructor, 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:-
This invention relates to improvements in machines for dressing or finishing
skins and hides.
.
In machines as hitherto manufactured for the smoothing, polishing, etc., of skins
and hides the latter are fed between rollers by means of a vertical plate which
moves up and down and which for changing the motion must be fitted with com-
plicated mechanism, and the skin or hide to be dressed or treated is hung over the
upper edge of this plate. "The disadvantages of such an arrangement consist in
the great loss of time and in the rapid wear of the working parts of the machine
due to the constant change in the direction of the motion and to the consequent
necessity for the frequent application of the brake.
Now it is the object of this invention to obviate these disadvantages and to this
end I arrange that the plates, which permit the skins or hides to be placed upon,
and removed from, them whilst the machine is in operation, are kept in constant
movement and are caused to pass between the rollers from below upwards by
means of suitably guided endless chains, guide strips or pins upon the lower ends
of the said plates compelling the said lower ends to remain within the frame of the
machine.

To enable my invention to be fully understood I will describe the same by.
reference to the accompanying drawings in which:-
:
Figure 1 is a side elevation of a machine constructed according to the invention:
Figure 2 is a front elevation thereof: .
Figures 3, 4 an. 5 are views of details; and,
Figures 6 and 7 are views illustrating a modification.
pass
The two endless chains a; which as they move upwards are caused to between
brushing rollers r, r¹ and smoothing rollers q, q¹ placed above the same, are
actuated by means of four chain wheels 1, 2, 3, 4 arranged in each standard or
support A of the machine. The plates b, b' which carry the skins, and which are
suspended freely to the chains a by pins z (Figures 4 and 5) are provided with an
elastic covering and at their lower ends with guide strips or pins u which are just
long enough to enable them to pass between the chains.. The chains a are kept
in constant movement in the direction indicated by the arrow Figure 1, during the
treatment of the skins, and at the same time the plates b, b¹ pass slowly between
the two pairs of rollers r, r and q, q' for spreading, smoothing and compressing
the skins or hides.

The machine is operated through the medium of a pulley on a shaft k having
toothed wheels h, h which drive wheels g, g on a second shaft f on which are
mounted the uppermost chain wheels from fast and loose pulleys on a main shaft v
which drives one of the rollers q at a slow speed by means of gear wheels w and o.
This roller slowly drives the other roller q' of the pair by means of gear
wheels, on the axles of the rollers and a pulley p on the axle of the first roller
drives, by means of a crossed belt, the pulley i actuating the chains as shewn in
Figure 1. Another pulley s on the driving shaft causes the brushing rollers
to rotate at a high speed by means of open and crossed belts and of the pulleys t, t¹.
Notches or recesses 6 and 7 (Figure 1) are made in the inner sides of the standards
or supports A of the machine, one set of the said recesses allowing only the
endless chains a with the pins z of the plates b, b' but not the guide strips u of the
plates to pass; the guide strips compelling the lower parts of the plates to remain
within the frame of the machine. A plate 8¹, arranged behind the rollers q, guides
the guide strips u as the plates move downwards.
r,
The skins or hides are laid upon the plates as the latter pass from the front
notches or recesses 7 in the supports to the lowermost chain wheels 4 placed
under the outer brushing roller r which is enclosed on the under side by a pro-
tective plate 8.
When the pins of a plate have passed over the lowermost chain wheel 4 the
plate will, after its guide strips u have passed the recesses 7 in the frame, be drawn
up between the two pairs of rollers and the skin or hide will be brushed by the
brushing rollers r, and spread and pressed by the metal rollers q, q¹.
As it passes from the upper chain-wheels 1 to the lower chain-wheels 2 arranged
at the back of the machine the skin or hide is, on account of the inclined position
the plate is caused to take by the guides at the rear of the supports, set free from
the outer side of the plate and when it reaches the lower rear chain-wheels 2 it is
laid either automatically or by a workman on a block 5.
The front metal rollers q¹ and r¹ are mounted on bent levers and are suitably
weighted with movable or adjustable weights. Adjusting screws d prevent the
rollers from striking one another after the plates have passed between them.
The skins or hides can be laid on the plates and those which have been treated
can be removed from the plates without stopping the machine.
In the slightly modified form of the machine illustrated in Figures 6 and 7 I
only employ two chain-wheels 1 and 2 for each chain and in this case the skins
or hides are placed upon, and removed from, the plates as the latter pass from the
upper chain wheels 1 to the lower chain wheels 2.
Having now particularly. described and ascertained the nature of my said

page_text: invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a machine for dressing or finishing skins and hides of the kind wherein
the said skins and hides are travelled by endless chains, freely suspending the
plates carrying the skins or hides and providing them at their lower ends with 5
guide strips or pins which compel the lower parts of the said plates to remain
within the frame of the machine and to assume a suitable position for enabling the
skins or hides to be placed upon and removed from them substantially as described
and illustrated.
2. The improved machines for dressing or finishing skins and hides herein before 1
described and illustrated in the accompanying drawings.
