UNITED STATES PATENT OFFICE.

Y JOSEPH DEISS, OF RANSPAOI-I, GERMANY, ASSIGNOR TO PATOHETT BROTHERS, OF HALIFAX, ENGLAND.

FASTENER FOR SECURING CARD-CLOTHING TO- BARS OF FLATS.

SPECIFICATION forming part of Letters Patent No. 564,052, dated July 14, 1896.

Application filed May 28, 1894. Serial No. 512,751. (No model.) Patented in England August 2, 1892, No. 13,925, and in France November 3, 1893,1To. 233,813.

To aZZ whom it may concern.-

Be it known that I, JOSEPH DEIss, a subject of the German Emperor,residing at Ranspach, WVesserling, Alsace, Germany, have invented a certain new and useful Improvement in Fasteners for Securing Gard-Clothing to Bars of Flats, (for which I have obtained Letters Patent in Great Britain, dated August 2, 1892, No. 13,925, and in France, dated November 3, 1893, No. 233,813,) of which the following is a specification.

This invention relates to an improved clamp-fastener for fastening the card foundation fabric to the flats of flat carding-engines, the object being to provide a fastener which can bypressure exerted thereon be riveted or clenched, thereby absolutely securing one edge of the fastener to the foundation fabric, as distinguished from the. metal clamps having serrated edges as at present used, the fastening of which is found to be unreliable.

In the accompanying drawings, Figure 1 shows part of a strip of metal from which a clamp-fastener is to be made according to my invention. Fig. 2 is a cross-section of Fig. 1. Fig. 3 is an end view of the clamp bent to position as when applied to the foundation fabric and flat. Fig. at is a cross-section of flat and card-clothing secured thereto by my improved clamp-fastener.

1 is the strip of soft steel as ordinarily used for making a clamp-fastener. The strip has on one edge and at intervals of its length small protruding pins or prongs, 2 of such length that, when forced through the card foundation fabric 3, their points, coming in contact with the iron flat 4, will, by the pressure exerted by the usual machines for fitting the clamp in its position on the bar, rivet, clench, or turn up the points of the said pins or prongs 2 in the form of fish-hooks in the foundation fabric, (seeFigs. 3 and 4,) thereby absolutely securing one edge of the fastener to the foundation fabric 3, the other edge being secured, as is customary, by bending and folding it under the bar, as at 5.

I would have it understood that I do not limit the invention to the exact form or shape of the protruding pins or prongs 2 so long as it is provided that the latter are constructed, when pressure is applied, to pass through the foundation fabric and their points turn up hookwise in the fabric, and also that said pins or prongs are separated from each other by spaces or intervals of the metal strip, so as to avoid damage and injury to the foundation fabric.

What I claim is- A clamp-fastener for securing the edges of card-clothing to flats, consisting of a flexible metal strip having turned-down pins spaced apart on one edge thereof and integral therewith, the pins being adapted to pass through the foundation fabric and to be turned upward in the form of a hook and clenched therein, while the other edge is adapted to be bent under the flat, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
