SPECIFICATION forming part of Letters Patent No. 761,470, dated May 31, ,1904.

Application filed October 11, 1902. Serial No. 126,876. (No modeI.) I

To all whom it may concern:

Be it known that I, DAVID GnssNER, a citizen of the United States, and a resident of -Worcester, county of Worcester, and State of Massachusetts, have invented a new and useful Improvement in Card Clothing for Napping-Machines, of which the following is a specification.

In my Patent No. 561,220 I haveshown in Figure/L a napping-roll in which the cardclothing is spirally wound on opposite sides of the central transverse plane. In practice the application of the card-clothing in this manner has been attended with difficulty in consequence of the tendency of any uncovered space extending circumferentially to produce Wrinkles in the cloth treated by the nappingroll. The card-clothing for napping-rollers is manufactured in narrow strips, generally from three-fourths of an inch to seven-eighths of an inch in width, and the problem of winding such narrow strips so as to produce an opposite spiral on each'half of the roll with the ends properly secured and without the objectionable circumferential vacant space above referred to is one that has not, I believe, been solved until my present invention.

In the accompanying drawings, Figs. 1, 2, and 3 represent in detail a form of fastening or buckle thatI prefer to use in carrying out my invention. Fig. t represents in plan and edge view an inserted piece or tongue employed in carryingout my invention. Fig. 5 is a detail showing a buckle part attached to said tongue. Fig. 6 is a central portion of a napping-roll containing my invention.

1- is thenapping-roll;

2 and 3 are the usual strips of card-clothing by which the opposite ends of the same are covered. 7

4c is a strip of the outline a b 0 d c f g 72, shown in Fig. 4.

5 is a screw by which the smaller end of each consist of a plate 7 containing the book and aplate k, containing the slot Z, with which said hook engages. The plates are respecpared in the form shown in Fig. 4 of-sufficient width from a to 7b to provide suflicient body at that point to give a secure hold for the screw 5, is secured at that end by such screw to the roll and is wound aroundthe roll until the ears 6 c and f g straddle the end a h, as shown in Fig. 6. The said ears have already been provided with buckle members corresponding to buckle members riveted to the ends of two card-clothing strips 2 and 3. Thereupon the said two card-clothing strips are secured by said buckles to said ears, respectively, and the napping-rollis turned, while the two strips are held in such position as to be wound in opposite spirals toward the opposite ends of the roll, being secured, respectively, to the opposite ends of the roll in any suitable manner.

Although I do not wish to limit myself to the form, of inserted strip or tongue shown in Fig. 4, nevertheless said'form possesses very portion of Fig. 4:. The wires 0 and p of the strips 2 and 3 are in lines parallel with the edges of those strips,'and their points are directed in planes parallel with such edges, so that when such strips are applied to the roll the points of their wires are directed in spiral lines diverging toward the opposite ends of the roll. The position of the wires is thus adapted for causing the cloth to keep its width It contains in passing through the machine and for reto show this divergence in spiral lines of the points of the wires of the strips 2 and 8. The slight space occupied by the screw 5 and the buckles 6 and 7, although not occupied by wires, extends principally longitudinally of the roll, and therefore has been found in practice to have no substantial tendency toward producing wrinkles.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an article of manufacture, a tapered tongue of card-clothing adapted to be secured at its smaller end to a napping-roller and at its larger end to the ends of two card-clothing strips.

2. As an article of manufacture, a card-clothing tongue, the side edges of which are at angles with the lines of'wires thereon.

3. As an article of manufacture, a card-clothing tongue, the side edges of which are at angles to the lines in which the points of its wires trend.

4. As an article of manufacture, a tapered card-clothing tongue, the field of its larger end presenting two widths for the attachment of card-clothing strips and an intermediate width corresponding with the smaller end of said tongue.

5. In combination,with the roller,two strips of card-clothing wound in opposite spirals and an intermediate card-clothing tongue.

6. In combination, with the roller,two strips of card-clothing wound in opposite spirals, an intermediate card-clothing tongue and means of attachment between said strips and said tongue.

7 In combination, with the roller, a tongue of card-clothing in which the lines of wire run circumferentially and two sections of cardelothing flanking the same in which the wires run in opposite spirals.

In testimony whereof I have signed my name in the presence of two subscribing witnesses.
