I, OSCAR CORDIER-LEVRAY, Mechanician, of Rue de Richelieu, 15, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as fol-
lows:-
This invention relates to a manual apparatus for mechanically cutting or
shaving short or long waste threads or clips, either longitudinal, transversal or
oblique that exist on the surface of tulles, laces, embroideries and other similar
articles after having been manufactured.
This apparatus is formed by the combination of a clipper or shears with a rotary
brush or an air blower forcing the loose threads, that have penetrated in the
teeth of the comb of the clipper, to come under the action of the cutting blades
or shears whatever be the length of these threads and whatever may be their
vertical, horizontal or oblique position, on the surface of the tulle, lace or em-
broidery.
This manual apparatus is provided with a handle held in the hand of the
operator so as to enable him to move it along on the tulle, lace, or embroidery, etc.
and to make the clips that are to be shaved by the to-and-fro movement of the
cutting blade, penetrate into the teeth of the fixed comb. This movement is
effected mechanically by means of a shaft passing through the axis of the handle;
and rotating by suitable means, either a rotating brush or to a blower so that the
hair of the brush or the air drives the waste threads or clips that have penetrated
in the teeth of the comb into contact with the cutting blade where they are im-
mediately cut on the edge of the tissue, without the latter being spoiled or deteri-
orated.
The shaft which passes through the handle can be either worked directly by
means of a small electric motor mounted on or in the said handle bar and con-
nected with a convenient source of electricity, or through a flexible shaft.

or Clips of Tulles, Laces, Embroideries and the like.
I, OSCAR CORDIER-LEVRAY, Mechanician, of Rue de Richelieu, 15, Paris, in the
Republic of France, 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 a manual apparatus for mechanically cutting or
shaving short or long waste threads or clips, either longitudinal, transversal or
oblique that exist on the surface of tulles, laces, embroideries and other similar
articles after having been manufactured.
This apparatus is formed by the combination of a clipper or shears with a rotary
brush or an air blower forcing the loose threads, that have penetrated in the
teeth of the comb of the clipper, to come under the action of the cutting blades
or shears whatever be the length of these threads and whatever may be their
vertical, horizontal or oblique position, on the surface of the tulle, lace or em
broidery.
This manual apparatus is provided with a handle held in the hand of the
operator so as to enable him to move it along on the tulle, lace, or embroidery, etc.
and to make the clips that are to be shaved by the to-and-fro movement of the
cutting blade, penetrate into the teeth of the fixed comb. This movement is
effected mechanically by means of a shaft passing through the axis of the handle;
and rotating by suitable means, either a rotating brush or to a blower so that the
hair of the brush or the air drives the waste threads or clips that have penetrated
in the teeth of the comb into contact with the cutting blade where they are im-
mediately cut on the edge of the tissue, without the latter being spoiled or deteri-
orated.
The shaft which passes through the handle can be either worked directly by
means of a small electric motor mounted on or in the said handle bar and con-
nected with a convenient source of electricity, or through a flexible shaft.
The construction of the movable cutter and the formation of the cutting blades
thereof are represented in the accompanying drawing. In this drawing similar
letters of reference designate similar parts throughout the several figures.
Figs. 1 and 2 are a front and side elevation respectively of the cutting or
shaving apparatus constructed according to this invention.
Fig. 3 is a vertical section of the apparatus along the axis of the operating
handle.
Figs. 4, 4, and 5 represent one constructional form of comb and cutter, and
Figs. 6, 6 and 7 represent another form of the comb and cutter or clipper of
the shearing machine.
The handle P is fitted internally along its axis with a metal tube a constituting
the casing for the transmission shaft o, which is provided with bearings o¹ ar-
ranged near its ends, so as to turn in the bores a¹ of the tube a, constituting the
bearing surfaces proper for the shaft o. The upper part of the shaft o is covered
by a sleeve b, fastened thereto by a pin b¹ and projecting beyond the upper
socket n which secures the handle P in its position. The sleeve b is provided with
a grooved pulley s. The socket n has an arm n² projecting from it, the reinforced
end n of which serves as a bearing and support for the axle q of two grooved
pulleys r. The sleeve b is provided with another pin 63, serving to connect a
shaft therewith which may, for example be flexible, or with another rotary driving
shaft,

page_text: The handle P has its lower part fitted into a socket c, cast in one piece with the
cover of the shearing mechanism, the socket c being provided with a side-arm c¹
serving, in this constructional form, for carrying the device which supports the
rotary brush. The brush-supporting-device is formed by an arm d, the end of
which is provided with a slotted hole d, in which the screw-threaded end c³ of
the arm can be adjusted and secured in position by a screw threaded nut e
screwed on to the part 2 and bearing against the arm d. The arm & has at its
other end a bored circular stem f affording a bearing for a shaft u, upon which
are fixed a grooved pulley t and the rotary brush g formed of bristles, or bundles
of metal or vegetable or animal products pass as closely as possible along the top
surface of the fixed comb of the shearing machine. The bristles. or fibres g¹ of
this brush may be replaced by a flexible metal blade of horn, celluloid or india-
rubber.
The shearing apparatus is formed of a comb 2 of metal, horn or other suitable
material fixed at the lower part of the cover h upon a tenon h², opposite the fixed
spindle i and by means of a removable screw-threaded spindle p³, which traversing
this cover is fastened thereto by means of a milled screw nut p³, the top flange
of which is cut so as to form teeth p³. The screw nut p² rests upon a flexible
washer and its screw spindle p, hollowed at its top end, has a small lever q
pivotted thereto. A small spring located in the hollow of the spindle pl acts
upon the end of the lever to maintain said lever normally in an approximately
horizontal position and so hold it in engagement with one of the teeth p5 of the
screw nut, thus locking the nut in position when the tightening is deemed suffi-
cient. In the interior of the cover a furcated lever k is pivotally arranged
mounted
upon the spindle i, and located in the furcated part k is a friction roller
on the eccentric knob o2 integral with the shaft o. The portion of the lever which
lies opposite the fork is provided with a projection which so engages with a
corresponding opening provided in the cutter m, as to impart to this cutter a re-
ciprocating movement between the comb p and recesses h², forming guides for
the cutter, so as to be displaced above the comb against the base of its teeth.
وا
The cutting blade is formed of a plate m, provided with teeth m¹ and a heel
piece m² resting upon the top surface of the comb. The face of the plate which
lies opposite the surface, to which the heel-piece m² is mounted is provided with
a groove m³, which engages with the outer-most projection h³ of the cover h, which
serves as a guide and support for the cutter. The plate m is provided with open-
ings affording passage to the tenon h¹, without thereby impeding its movements.
A gut-string or a leather strap passing over the pulleys s, r and t admits of
motion being simultaneously imparted to the cutting blade m and to the brush g
by the rotation of the shaft o.
The teeth of the comb preferably receive the shape represented in Figs. 4 and 6,
that is to say, each tooth is rounded at its extremity and the clearings p between
the teeth are narrower at their open part than near the base of the teeth, where
the clearings are likewise rounded. The cross section of the teeth is triangular
as represented in Figs. 4 and 6. The teeth may also be slightly, bulged or the
angle at the apex of the triangle may be made more or less open, so as to cut
the threads more or less closely upon the fabric. Owing to the narrowing 7 of the
clearings, the threads freely moving in these openings 2 have the tendency of
descending more or less toward the base of the teeth, so as to come in a more cer-
tain contact with the cutting parts of the cutting blade.
The teeth of the cutter m may be either triangular, as represented in Fig. 7,
or cut normally at their free end and in this case the clearing m is narrower at
the outer opening than at the base, as represented in Fig. 5.
It is evident, that in proportion as the operator engages the loose threads
with the teeth of the comb p, the brush forces these threads towards the base of
the teeth in contact with the cutting blade or tool m, which by its rapid and con-
stant reciprocating movement cuts these threads clean off the fabric.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
1. A tool for cutting or severing loose longitudinal, transverse or oblique threads
from tulle, lace, embroidery and similar fabric, consisting of a hollow. handle,
arranged perpendicularly to the plane of the blades of shearing mechanism, the
cutting blade or cutter of which receives a reciprocating movement opposite a
rotary brush forcing the loose threads towards the base of the teeth of the comb
into contact with the teeth of the cutter; the said handle receiving within its
axis the rotary shaft, actuated by a flexible shaft or by an electric motor either
directly connected to, or independent of the handle and imparting a simultaneous
inovement to the cutter and to the brush, substantially as described.
2. The formation of the teeth of the comb and of the cutter, so as to present
clearings, which are narrower at the outer opening, than at the base, in order
to bring the loose threads more easily within reach of the cutter, substantially as
described.
3. The particular construction of the removable spindle for securing the comb
and the cutter in position the same being provided with a head or nut, the edge
of which is notched so as to admit of a lever being arranged in one of these notches
which lever is actuated by a spiral spring, located in the chamber or recess, pro-
vided in the extremity of the screw threaded stem of the said spindle, substantially
as described.
