Improved Machine for Shearing or Trimming the Margins of Cloth or
Fabric.
I, GUSTAV JOSEPHY, of the Firm of G. Josephy's Erben, of Bielitz, Austrian
Silesia, Manufacturer, do hereby declare the nature of said invention to be as
follows:-
The longitudinal shearing machines, hitherto generally used in removing
uprightstanding hairs and other projecting parts of clothes or fabrics and in
smoothing the upper face of textile fabrics, are attended with the disadvantage
that they leave at either end of the piece of cloth a strip or margin which has
to be sheared separately as the actual shearing or cutting mechanism cannot be
brought sufficiently close to the seam. In order to shear or trim these margins
and ends Levis' or Davis' transverse shearing machines are resorted to in prac-
tice. These machines however involve the necessity of winding the goods first
upon one roller, so as to trim one of the margins, and then from that roller on
to a second roller, whereon the other margin is trimmed; and when the marginal
shearing is thus completed the material has to be unwound from the second
roller, so that this process involves three successive operations, viz. the winding
of the cloth on one roller, its transfer to another roller and its unwinding from
the latter. The performance of these operations requires two attendants and
entails an expenditure of time quite out of proportion to the amount of useful
work performed, considering especially that the width of the margins to be
sheared or trimmed, scarcely ever exceeds 200 or 300 millimetres. Besides, the
shearing machines used for the purpose, being generally constructed for a cut"
of at least 1.160 metres wide, take up a large space; the shearing table or bench,
together with the shearing device or cutter, of the cross-shearing machines
heretofore known, being supported by a spectacle-shaped frame or structure
forming the connection between the two side frames or cheeks of the machine,
while the material is made to pass under the cutting or shearing device through
the spaces, left free between the said cheeks.
«
The object of the present invention is to provide means whereby a consider-
able saving of time and space; simplification of the work, and effectual protec-
tion of the goods are effected, the goods as they come from the longitudinal
shearing machine, in uncovered or open layers, being conducted into a machine
so constructed, according to this invention, as to directly shear or trim the
margin of the cloth as it is supplied from the longitudinal or main shearing
machine. In the improved machine the cutting or shearing device, and the
bench or table, which is left free on one side, are arranged in such a manner
that the material to be trimmed enters the mechanism laterally and is thereby
protected from damage.
The shearing device proper, namely the cutter roller and its under cutter, may
be supported in a sliding voke, preferably in the shape of a stirrup frame, the

page_text: shearing table or bench being also connected to said yoke or frame, but so that
an open space is left at its opposite end.
This sliding yoke is adapted to travel on the suitably shaped upper edges of
the cheeks of the machine frame, the latter being fitted with means, such as
nippers, hooks or the like for firmly holding the cloth, at one end, and with
other means at the opposite end of the frame, such as bands or chains, forming
a stretching device for adjusting the required distance within the whole length
of the machine, in accordance with the width of the cloth or fabric to be operated
on, and thus to secure the proper stretching of the said cloth.
The cloth or fabric piled up next to the machine, from the rest, passes over a
suitable guiding beam, but under the cheek of the corresponding side frame up
to the shearing table or bench, whereupon it is fixed in position by the said
holding and stretching device and the shearing gear then comes into operation.
Inasmuch as the machine itself is unencumbered by any appliances requiring
much room, it may be built as narrow as may be desirable, say from 200 to 300
millimetres downwards.
The practical advantages afforded by this new machine by simplifying the
work and thereby reducing its cost, are obvious, since the tedious operations of
winding and unwinding the cloth backwards and forwards, which have been
unavoidable hitherto, are by the present contrivance rendered unnecessary, so
that an equal or greater output can with the new machine be secured at the cost
of less labour, both the number of hands employed and the space occupied by
the apparatus being greatly reduced.

COMPLETE SPECIFICATION.
Improved Machine for Shearing or Trimming the Margins of Cloth or
Fabric.
I, GUSTAV JOSEPHY, of the Firm of G. Josephy's Erben, of Bielitz, Austrian
Silesia, Manufacturer, do hereby declare the nature of said invention, and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to machines for shearing or trimming woven fabrics, such
as cloth, in which a spirally wound cutter (cutter roller) operates in conjunction
with an under cutter and the object of my invention is to provide for means
especially for shearing the margins of cloth left at either end of the piece pre-
viously treated on the longitudinal shearing machines now in use.
The longitudinal shearing machines, hitherto generally employed in removing
upright standing hairs and other projecting parts of clothes or fabrics, and in
smoothing the upper face of textile fabrics, are attended with the disadvantage
that they leave at either end of the piece of cloth a strip or margin which has
to be sheared separately as the actual shearing or cutting mechanism cannot be
brought sufficiently close to the seam. In order to shear or trim these ends
Levis or Davis transverse shearing machines are resorted to in practice. These
machines however involve the necessity of winding the goods (as shewn in
Figure 1 of the accompanying drawings) first upon one roller a, so as to trim
one of the ends, and then from that roller on to a second roller b, whereon the
other end or margin is trimmed; and when the marginal shearing is thus com-

page_text: pleted, the material has to be unwound from the second roller b, so that this
process involves three successive operations, viz. the winding of the cloth on one
roller, its transfer to another roller and its unwinding from the latter. The
performance of these operations requires two attendants and entails an expend-
ture of time quite out of proportion to the amount of useful work performed,
considering especially that the width of the ends to be sheared or trimmed
scarcely ever exceeds 200 or 300 millimetres. Besides, the shearing machines
used for the purpose, being generally constructed for a "cut" of at least 1.160
metres wide take up a large space; the shearing table or bench t in the said
Figure 1 of the drawing, together with the shearing device or cutter m of the
cross-shearing machines heretofore known, being supported by a spectacle.
shaped frame or structure e forming the connection between the two side frames
or cheeks of the machine, while the material is made to pass under the cutting
or shearing device through the spaces o, left free between the said cheeks.
Now, according to my invention, the goods, as they come from the longitu
dinal shearing machine, in uncovered or open layers, are conducted into a
machine so constructed, as to directly shear or trim the end of the cloth as it is
supplied from the longitudinal or main shearing machine. In the improved
machine the cutting or shearing device, and the bench or table, which is left
free on one side, are arranged in such a manner that the material to be trimmed
enters the mechanism laterally and is thereby protected from damage.
I attain these objects by the mechanism illustrated in the accompanying draw-
ings, in which Figures 2 is a cross-section, Figure 3 a plan, and Figure 4 a
longitudinal section of an example of a marginal shearing machine constructed
in accordance with this invention. The shearing device proper, namely the
cutter roller m and its under cutter, are supported in a sliding yoke or stirrup
shaped frame p. The shearing table or bench is also supported by the said
frame but is connected thereto at one end only, having an open space fat
its opposite end.
The sliding frame supporting the shearing gear is adapted to travel on the
suitably shaped upper edges of the sides or cheeks ss of the machine frame
which frame is fitted at one end with a series of stationary nippers, hooks h or
equivalent means, for firmly holding the cloth w, while at its other end similar
devices are arranged upon a carriage d. This carriage may be connected to
a stretching roller g by means of bands or chains e, or be made controllable from
some other equivalent device, so as to enable it to be adjusted at any required
distance from the other end of the machine in accordance with the width of the
cloth to be operated on and thus to ensure the proper stretching of the said cloth
The cloth folded or piled up next to the machine, from the rest, is drawn upon
the tablet over the beam i and under the cheek of the side frame s; whereupon
it is fixed in position by the devices h h¹, and the shearing gear then comes into
operation.
Inasmuch as the machine itself is unencumbered by any appliances requiring
much room, it may be built as narrow as may be desirable, say from 200 to 300
millimetres downwards.
The practical advantages afforded by this new machine by simplifying the
work and thereby reducing its cost, are obvious, since the tedious operations of
winding and unwinding the cloth backwards and forwards, which have been
unavoidable hitherto, are by the present contrivance rendered unnecessary, so
that an equal or greater output can with the new machine be secured at the cost
of less labour, both the number of hands employed and the space occupied by
the apparatus being greatly reduced.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
A nap or pile shearing machine wherein the cutting or shearing mechanism

page_text: proper and the table or bench, which is free on one side are so arranged that the
material to be operated upon enters the machine laterally thereby enabling the
margins or ends to be sheared.
