To aZZ whom it may concern.-

Be it known that we, JAMES HoYLE SMITH, fustian-master, residing at Longsight, Manchester, in the county of Lancaster, ANDREW GODDARD, warehouse-manager, residing at Stockport, in the county of Chester, and LLOYD I-IIGGINBOTTOM, engineer, and THOMAS MANNOOK, engineer, residing at Longsight,

England, aforesaid, all being subjects of IO the Queen of Great Britain, have invented certain new and useful Improvements in Knives for Cutting Pile Fabrics, (for which Letters Patent have been obtained in Great Britain, No. 11,437, dated August 22, 1887,

and No. 16,996, dated December 10, 1887; in Germany, patent of addition, November 24, 1887, on No. 46,146, of September 21,1887; in France, patent of addition, October 6, 1888, on No. 186,020, of September 22, 1887; in Austria-Hungary, dated January 11, 1891, No.

38,959; in Belgium, patent of addition, Octoher 6, 1888, No. 83,503, on No. 78,926, of September 19, 1887, and in Italy, dated September 29, 1890, No. 28,397, issue date October 2 5 80, 1890;) and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

0 The knife which forms the subject of our present invention is more particularly intended for use on the machines for cutting the pile of velvets, fustians, plushes, and other pile fabrics, for which we have filed applications for Letters Patent. The common fustian-cutters knife, which is used on the ordinary fixed frame, may be used on our said machines; but should the knife puncture the fabric, as it is liable to do, the high speed at o which the fabric runs does not allow time to withdraw the blade before a long tear or split is caused. In our improved knife the out ting-blade is fastened to a hinged carrier in such a manner that if the blade does pierce the fabric it is automatically released and instantly swings around, permitting the material to slip off the knife.

In the accompanying sheet of drawings, Figure 1 is a side View, and Fig. 2 a plan, of a knife constructed according to our invention.

ais the handle, preferably formed, as shown, of two flat strips of wood with distance-pieces between them.

In Fig. 1 part of one side of the handle is broken away to show the construction more clearly.

The knife-blade d, which is of the usual form, is held in a carrier 0, which is pivoted in the end of the handle a at c. A trigger h is pivoted in the end of the handle a. at .h', and is adjustable for length by means of the piece 2', which is notched to receive the knife cl. An arm j is pivoted to the upper part of the trigger it at j and, rests upon a cross-bar Z in the handle. A notch m in the carrier 0 engages with the end of the arm j, and a flat spring 6, fixed to the handle, presses the carrier down upon this arm.

The position of the parts of the knife when ready for use is as shown in the drawings; but if the knife enters the cloth the trigger h is pushed away by the cloth sliding up the' blade and draws the arm j out of the notch m. The spring 6 then pushes down the carrier and leaves it free to turn around into the position shown by the dotted lines, so that as the fabric passes along it slips off the knife with perfect freedom Without any danger of tearing the said fabric and leaves only a small puncture, which is practically invisible. A triangular projection C is fixed on the under side of the handle, and in using the knife this projection is pressed up against a ledge on the table of the machine, so that the point of the knife always projects to the same distance from the edge of the table and lies at the correct angle on the material, and the pro j ection C,being broad 011 the base,insures the knife being held upright, which is very important. 9o

Having fully described our invention, What we desire to claim and secure by Letters Patent is- 1. A device for cutting pile fabrics, consist- 5 ing of a handle having a movable knife, in combination with a trigger normally holding the knife in position,but adapted to be moved to release the knife, the latter when released being free to be automatically withdrawn 10 from the fabric, subtantially as described.

2. A device for cutting pile fabrics, consisting of a handle having a movable knife, in combination with a trigger normally holding the knife in position, but adapted to be moved :5 to release it, and a spring to start the knife when released, substantially as described.

3. A device for cutting pile fabrics, consisting of a handle havinga knife pivoted thereto, in combination with a trigger normally holding the knife in position, but adapted to 2c be moved to release the knife, the latter when released being free to swing round and be withdrawn from the fabric as the latter moves, substantially as described.

In testimony that we claim the foregoing 2: we have hereunto set our hands this 6th day of March, 1888.
