Improvements in Apparatus Employed in Cutting the Pile of Weft
Pile Fabrics.
I, GEORGE ROGER, of 34 Ellesmere street, Warrington, Lancashire, Master
Fustian Cutter, 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 :-
The improvements relate to apparatus for cutting the pile of weft pile fabrics,
wherein two or more lengths of cloth overlapping each other are stretched upon
one cutting frame, in manner such as is described in the specification of Letters
Patent granted to me, and numbered 5065 of 1892 and the improvements have
for object to obviate an evil hitherto for the most part attendant upon the cutting
of overlapping lengths of fabric, and to be hereinafter described.

In the cutting of weft pile fabrics on the hand frame, the cloth, as is well
known, is stretched upon the frame for a portion of its length at a time, and is
passed, at one end of such frame, over a board or cross-piece, called the "spear,"
having a sharp edge, which, by causing the cloth to dip sharply, enables the knife
to run out of each race in uniform manner across the piece.
But in cases where two overlapping fabrics are cut at one time, it is found in
practice that this advantage is not sufficiently obtained in cutting the upper length
of cloth. inasmuch as the double piece of cloth, when passing over the spear, causes.
a rounding off of the edge of the upper piece referred to in place of the sharp,
angular bend required; and, consequently, the running out of the knife from the
races of the upper piece is for the most part unsatisfactory, producing results which
detract from the appearance of the finished fabric.
To obviate this defect, and to carry out my improvements, I employ apparatus
which I will proceed to describe with reference to the accompanying sheet of
drawings, wherein Fig. 1 is a longitudinal section, and Fig. 2 a plan view of part
of one end of a cutting frame furnished and arranged in accordance with my
invention.
The same letters indicate corresponding parts wherever they occur.
"
"
Upon any convenient part of the frame a, and by preference behind the ordinary
spear as shown, I mount a special and extra spear c which may be of
metal, wood, or other substance as may be found most convenient, and of any
suitable shape in cross-section, but so as to present the requisite sharpness of edge.
This special spear is preferentially arranged at such position, vertically, that the
upper fabric & is lifted from contact with the lower fabric e as shown, in order to
avoid injurious marking of the latter by any pressure or friction upon its pile
surface, at or near the edge of the spear b, and for the same reason, I prefer also
to provide a special spear for the upper fabric d at the opposite or setting in
extremity of the cutting frame, (not shown in the drawings); which last-named
spear may be formed with or without the sharp edge, as desired.
In like manner, where more than two pieces are stretched in one frame, each
piece may be provided with a separate spear or spears.
The tightening rollers f, g, may be of the ordinary or any other convenient

page_text: character, and are mounted in such manner as to enable the cloths d, e, to pass
freely thereto over their respective spears. A suitable stop or stops may be pro-
vided, when requisite, to prevent the knife point from coming in contact with the
special spear during the cutting of the lower fabric.
Variations in detail may be made, such as in the material, dimensions and desigu
of the extra or special spears, and in the method of mounting the same, without
departing from the peculiar character of the invention.
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:
In weft pile cutting frames where two or more pile fabrics are stretched at one
time, one overlapping another, a special and extra "spear" for each overlapping
length of cloth at one or both ends of the frame, for the purpose and in manner
substantially as hercin shown and described.
