rhis invention has reference to apparatus for cutting cloth along its length and has for its object to provide a simple an-d convenient apparatus for this purpose which may be attached to a loom to cut the cloth as it is woven, or to a machine on which a roll of cloth is mounted and is wound off on to another roller or rollers.

Apparatus for cutting cloth according to this invention comprises one or more cutters each -comprising a blade and a blade holder, the latter being slidably mounted on supports mounted on or forming part of the loom or other machine on which the apparatus is used, with the blade or blades facing the cloth as it is wound on to a roller or rollers whereby by adjusting the blade holder or holders on their supports the width of the cloth, the cloth may be cut or slit into any desired widths.

The invention is more particularly set forth with reference to the accompanying drawings wherein- Fig. 1 is a front elevation of apparatus according to the invention.

Fig. 2 is an end elevation.

Fig.13 is a plan.

Fig. 4 is a perspective view of a bracket and Fig. 5 is an end view of a securing collar.

The apparatus which is shown in the drawings as applied to a weaving loom, comprises a bracket 6 mounted at each end of the loom breast 1, over which the cloth, not shown, passes to the take-up roller. The brackets 6 project forward of the loom breast 'I and toward the oncoming cloth. Each bracket 6 is `provided with two holes 8 and 9 one below and in front of the other, and through these holes there are passed two wires or rods I which are secured in place by nuts or other fastening means, on the outside of the brackets 6.

Slidably mounted on these wires or rods II) are blade holders II each comprising two complementary parts I2, each of substantially rightangled triangular shape, the vertical edge being toward the loom breast I and the hypotenuse toward the oncoming cloth; the hypotenuse being bevelled at I3 on the outside. These holders have holes corresponding with the holes 8 and 9 in the brackets and between them is a third hole provided with a short screw and nut I4, and the top hole has extensions I on the outside faces in the form of collars, provided with grub screws I6, the collars affording a larger bearing face on the top wire or rodV Ill than can be obtained only by the width of the holder, and the grub screws I6 providing means whereby the holders can be clamped at any position desired along the wires or rods IU.

The blade II used in the holders is `a thin steel blade having three aligned holes in it, and for this purpose a safety razor blade may be used. The holes in the blade i'I are so aligned and spaced that when the blade is mounted in the holder I I the top wire or rod IU will pass through the top hole of the blade holder II and blade I'I, the :bottom wire or rod I0 will pass through the bottom hole 9 and the securing screw I4 will pass through the middle hole, and secured by a nut will clamp the sides I2, I2 of the blade holder and the blade I'I tightly together.

It will be appreciated that the blade I'I is inclined upward and away from the cloth, as it passes to the breast beam I so that as the cloth encounters the blade the effect is that of a sliding cut, and owing to the bevelled edges of the holder, forming together la V or wedge shaped edge the blade is held in a central position between any two adjacent warp threads between which it may be placed, the warp threads thus being guided to the sides of the blade and being protected from damage by the blade, which might be caused by any irregularity of movement of the cloth.

In using the apparatus the wires or rods I0 are secured in the bracketsV 6 at one end, and the holders II with the blades I'I mounted in them are threaded on the wires or rods after which the latter are secured at the other ends in the brackets and the holders are adjusted to and secured in their cutting position. The wires or rods I0 are not intended to be rigid but to be slightly flexible so as to allow a certain amount of give to the vibration of the cloth.

While the invention has been described as applied to a loom it will be understood that it can just as easily be applied to any other machine in which cloth is wound .from a roller on to another roller or rollers. It will also be understood that any desired number of cutters may .be used according to the width required for the final width or widths of the cut strips.

What I claim as my invention and desire to secure by Letters Patent is:

A cloth cutting apparatus having .a `pair of transversely extending, non-rigid rods disposed one above the other and in Adifferent vertical planes, blade holders supported for sliding movement along said rods and each comprising a pair of right-angled triangular plates having openings for the passage of said rods, that edge of each of said plates forming the hypotenuse of the triangle being bevelled and each plate having a collar eX- tending laterally therefrom in encircling relation to the opening for one of said rods and a radially extending screw threaded into each of said collars for clamping the plate on said rod, and means for clamping each pair of plates together.

JOHN SLINGSBY TAYLOR.
