Complete Accepted, 27th Sept., 1887.
We, EDWIN MARTIN, of Wellington Mills, Lindley, near Huddersfield, Yorkshire,
Manufacturer, THOMAS FRED DRAKE, and JOHN WILLIAM JOHNSON, of the same
place, Finishers, do hereby declare the nature of this invention to be as follows:-
This invention has reference to prior Letters Patent granted to the said Edwin
Martin and Thomas Fred Drake on the 12th of February A.D. 1885 No. 1931.
The invention comprised in such Patent consisted in the use of an elastic tube over
which the cloth traversed as it was being sheared or cropped by a rotary knife above
it. The special use of such tube was to allow the knots under the cloth to sink or
be depressed into the said elastic tube so as to prevent damage to the cloth by the
rotary knife.
In practice we have found that the friction of the cloth in passing over the tube was
sometimes sufficient as to roll or force the tube out of the bed or groove in which it
was partially inserted.
The object of our present invention is to provide means to prevent the travelling fabric
from pulling the tube out of its bed or groove, and this we accomplish by making the
tube with one or more projecting flanges which are inserted in the bed and held fast
by screws, bolts, or other means; or the tube may be covered or wrapped around with
a narrow sheet of india rubber or other substance, the longitudinal sides of such
covering being held fast in the cutting bed by any glutinous substances, or by screws,
bolts, or other suitable means. By this means the travelling cloth cannot force the
tube from its bed as is now the case.

Finishers, 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 has reference to prior Letters Patent granted to the said Edwin
Martin and Thomas Fred Drake on the 12th day of February A.D. 1885 No. 1931.
The invention comprised in such patent consisted in the use of an elastic tube over

The special use of such tube was to allow the knots under the cloth to sink or be

knife.
In practice we have found that the friction of the cloth in passing over the tube was
sometimes sufficient as to roll or force the tube out of the bed or groove in which it
was partially inserted.
The object of our present invention is to provide means to prevent the travelling
fabric from pulling the tube out of its bed or groove, and this we accomplish by
making the tube with one or more projecting flanges which are inserted into the bed,
and held fast by screws, bolts, or other means; or the tube may be covered or wrapped
around with a narrow sheet of india rubber or other substance, the longitudinal sides
of such covering being held fast in the cutting bed by any glutinous substances, or by
screws, bolts, or other suitable means.
In order that our invention may be more fully understood, we will make reference
to the accompanying sheet of drawings illustrative thereof, wherein Fig. 1 is section
of a cutting bed such as is used in machines for shearing or cropping fabrics by
means of the rotary helical cutter a. Our india rubber or elastic tube, which is shewn
at b, formed the subject of a prior Patent granted to present applicants No. 19,318.
This tube we now propose to make with a projecting rib or flange c, which elastic
tube and projecting flange are made secure in grooved bars d and e. The rib c is
fastened in position either by glutinous substances or by bolts f; by which means the
travelling fabric shewn at 9 cannot roll or force the tube out of its groove, as it
sometimes did without the use of the rib c.
Fig. 2 shews that the tube 6 may be formed with two ribs or flanges c and c³, and
made secure to the grooved bar d by plates h and bolts f.
In Fig. 3 we shew that the tube b may be kept in position by means of a thin piece
of india rubber or other suitable material; placed over the top of the tube, the
longitudinal sides of such thin piece of india rubber or other material being

wrapped around the said tube b as shewn in Fig. 4, and the longitudinal edges thereof,
made secure by being passed down between the two parts of the grooved cutting
bed d and e, and secured together by bolts f. It will be necessary for the material j
to be thin and pliable, so as not to destroy the effect of the yielding tube b.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
The several means and methods substantially shewn and described herein for
preventing the yielding tube 6 from being forced out of the grooved bed by the
friction of the travelling fabric.
