UNITED STATES PATENT OF ICE.-

FRITZ PASTOR, OF KREFELD, GERMANY.

METHOD O1: FIGURING VELVET.

To all whom it concern:

Be it known that I, FRITZ PASTOR, silk and velvet finisher, a subject of the King of Prussia, German Emperor, and resident of Krefeld, in the Province of the Rhine, in the Kingdom of Prussia, German Empire,

have invented an Improved and useful Method of Figuring Velvet, of which the following is a specification.

This invention is based, first, on the fact that some vegetable and animal threads are more or less heat-proof than other vegetable and animal threads; second, on the oognizance that this behavior of the material, of

which the threads consist, may be usefully employed for figuring velvet of,t-he kind, in which the threads forming the pile are less heatproof than the threads forming the ground-fabric. This is the case particularly-with velvet, in whichthe pile-threads consist of cotton and the weftand the warp-threads consist of silk.

In carrying my invention into praetice, I heat the velvet on its back-side at those portions where it shall become figured on its front-side. This heating is effected by embossed plates or rollers, the embossed por-' tions showing the figuring which shall be is to say, they have no more the power to hold in place the corresponding portions of" the pile on the surface proper of the velvet, which is proved by the fact, that these portions may easily be removed from that surface by means of a brush. There becomes thus v1sible at these portions the upper surface of the ground-fabric, and these portions of the silken ground-fabric represent the figuring to be roduced.

celerated by providing the velvet by any of the known dressing or finishing methods with appropriate means, I have found that The before-described process may be ac- Specification of Letters ratent. I Patented Sept. 10-, 19 12. Application filed April 1, 1912. Serial No. 687,933. i

by. thus preparing the velvet, the cotton pilethreads become more easily friable and can more easily be removed after the heating.

Having now described my invention, what I desire to secure by a patent of the United States is:

l. The method of figuring velvet of the kind in which thematerial of the pile is less heatproof than is the material of the groundfabric, consisting in heating the velvet on its back-side at those portions Where-it shall become figured on its front side so as to render friable the respective portions of the material of the pile and'making them thereby removable, and removing said pile-portions.

2. The method of figuring velvet of a kind in which the threads forming the pile are less heatproof than are the threads forming the ground-fabric, consisting in heating the velvet on its rear surface at those places where it shall show figures on its front-surface, said heating being such as to render the respective portions of the pile-threads friable and making them thereby capable of being removed, and removing said portions of the pile-threads;

3. The method of figuring velvet of the kind in which the material of the threads forming the pile is less heatproof than is the material of the threads forming the ground-fabric, consisting in heating on the under side of the velvet parts of such ex-v tent' and contours as correspond to the fig it shall become figured on its front-side 'so' as to render friable the cotton-thread portions exposed to the heat and making them thereby removable from the upper side of the velvet, and removing said cottonthread portions.

' 5. The method of figuring velvet, consistfinishing method with appropriate means, heating the thus prepared velvet on its rearing in providing the velvet by a dressing or surface at those places Where it shall show In testimony whereof I aflix my signature figures on its front-surface, said heating in presence of two witnesses. being such as to render the respective portions of the pile-threads friable and making FRITZ PASTOR 5 them thereby capable of being removed, and Witnesses removing the said portions of the pile- GEORG VON BEOKERATH,
