Specification of Letters Patent.

Patented. Jan. 12, 1909.

Original application filed June 8, 1908, Serial No. 437,4:60. Divided and this application filed September 3, 1908.

Serial N To all whom it may concern:

Be it known that I, FRANK \VINnsoR DENI- soN, a citizen of the United States of America, and resident of 55 Papineau avenue, in

the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in a Machine for Cutting Lengths of Cloth or other Material; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in a machine for cutting lengths of cloth or other material, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts whereby the material is carried with the lateral movement of the knives in relation to the frame of the machine and the line of out not disturbed.

The objects of the invention are to supply 2 5 a simple means of cutting strips of material particularly for such uses as belting, to save waste of material by obviating any chance of the cut getting out of line, and generally to devise a cheap and efficient machine.

The drawing is a perspective detail of the mechanism apart from the frame.

Like numerals of reference indicate corresponding parts in each figure.

The present a plication is a division of application Seria Number 437,460, filed on the 8th of June, 1908. f

Referring to the drawing, 1 is the bale of material carried on the shaft 2, said shaft being suitably supported in a frame.

3 1s a tension roller journaled in suitable bearings in a suitable frame in advance of the shaft 2.

4: and 5 are rollers .journaled in a suitable frame at a higher elevation than the roller 3 and on the same level, but spaced apart and parallel.

6 is a rod parallelly arranged in the space between the rollers 4 and 5 and supported thereabove by the brackets 7, said rod having a limited slidable movement in its supports.

8 are knives adjustably mounted on the rod 6 and set at any desired position thereon and also arranged to extend downwardly into the space between the rollers 4 and 5 so that when the cloth material is stretched over said rollers, the knife or knives will penetrate the said cloth or material.

9 is a guide adj ustably secured on the rod 6 and having a fiat face below said rod adapted to engage the edge of the material passing over said rollers at and 5, said guide being arranged and set on said rod 6 by a suitable set screw extending therethrough and abutting said rod.

10 is a spiral spring encircling the rod 6 inside the bracket 7 and arranged to keep the guide 9 always in contact with the edge 12 of the material, the collar 11 being fixedly mounted on the said rod 6, against which one end of the spring is placed, the other end abutting the bracket 7. It will be thus seen in any movement of the material passing over the rollers in a lateral direction in relation to the frame of the machine, the guide 9 will always follow the edge of the material which it abuts and as the guide 9 and the cutting knife 8 are held rigidly, the same distance one from the other, no variations can occur in the line of cut in the material for it must always be the same width as the length of rod between the knife and the said guide, until said knife is readjusted for a different width.

The means of drawing the cloth over the rollers 4 and 5 is neither described nor is it illustrated in the present papers, for the reason that it may be done in so many ways, that is to say, this mechanism may form part with another machine, or else the rollers 4E and 5 may be driven and be of larger diameter than shown and so carry the goods thereover without any further assistance, and again the material may be drawn over by another roll, which may be the receiving roll, therefore, any suitable means as already stated may be employed for insuring the c0ntinuous forward movement of the cloth or other material, further, itmay not be absolutely essential to the operation of the invention to have a pair of rolls as arranged, that is, a parallel pair of rolls, for one roll might operate equally well and the out be made on top of that roll into suitable grooves thereon.

Various modifications may consequently be made, without departing from the spirit of the invention.

WVhat I claim as my invention is:

1. In a machine for cutting lengths of rod in fixed positions in relation to said knife, and a spring cushion cushioning said rod between said guide plate and the rod support.

2. In a machine for cutting lengths of cloth or other material, a pair of rolls, suitably spaced and supporting the material in passage, a rod supported between said rolls longitudinally in relation to said roll and adjacent thereto and lengthwise movable, a knife adjustably secured to said rod and arranged to extend into the material passing over said main roll, a guide plate adjustably secured on said rod in fixed positions in relation to said knife, and a spring cushion cushioning said rod between said guide plate and the rod support.

Signed at the city and district of Montreal, in the Province of Quebec, in the Dominion of Canada, this third day of August, 1908.

FRANK WINDSOR DENISON.
