METHOD OF MAKING PAPER-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 341,432, lated May 4. 1886.

Application filed November 4, 1885. Serial No. 181.835. (No model.)

To all whom t may concern:

Beit known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Springfield, in the county of Hampden, State of Massachusetts, have invented certain new and useful Improvements in Methods of Making Paper-Fasteners, of which the following is a specification.

This invention relates to vmethods for making of fabric that class of paper-fasteners described and claimed in my application Serial No. 178,073, filed September 24, 1885, which fasteners consist of two thicknesses united at about the middle, and have four free ends.

The invention has for its object the making of such fasteners of a single piece of textile fabric, as hereinafter set forth.

In the drawings accompanying and forming a part of this specification, Figure l is a side view of a piece of woven or knitted fabric. Fig. 2 is an edge view of the same. Fig. 3 is an enlarged end view of a strip ent from said fabric. Fig. 4 is a similar side view of the same. Figs. 5 and 6 are respeetivelya greatly-exaggcratcd side and an end view of the strip of woven fabric, showing` how the threads are arranged.

Similar characters in all the figures.

In carrying myimproved method into effect I first prepare a woven or knitted fabric, A, which consists of two thicknesses, C D, formed into one at regular intervals, as at E, during the process of manufacture. This fabric is then cut on lines a a I) b, Figs. 1 and 2, thus producing the strip shown in Figs. 3 and 4, having the four free edges 2, 4, 6, and 8, all united at E. From this strip the fasteners are cut, as indicated by dotted lines at d, e, and f. Fig. 3 is substantially an edge View of the completed fastener, which has the four similar free ends, 2, 4, 6, and S. The outer (or inner) surfaces of all the ends are now coated with an designate the same parts adhesive substance-as glue, gum-arabic, or the like-when the fastener-is ready for use.

Of the two kinds of textile fabric above mentioned I prefer to use that produced by the method of weaving. Such a fabricI have shown on a very large scale in Figs. 5 and 6. Each of the two parts C and D is composed of the usual warp and filling threads, of which those of the Warp are in some way interlocked at E with the filling or Woof of the opposite part. This is readily accomplished by means of ordinary Jacquard looms by methods that are well known to those familiar with that class of weaving machinery. 'The method I prefer is shown in Fig. 6, wherein the warpthreads cross over each other at E, those from end 2 running into end S, and from end 4 into end 6. Two of these threads are designated, respectively, by3 and 5, the woof being designated by 9. In practice I con sider that it will be sufficient if abouttonehalf of the warpvthreads are crossed, as described, the remainder continuing each in the same part C or D.

In this application I make no claim to the improved fabric herein described, having` described and claimed the same in another application of even date herewith.

Having thus described my invention, I claim- The improved method herein described of making flexible paperfasteners of the class specified, it consisting in first preparing the material into a double-thickness woven or knitted fabric united substantiallyT as described, and then cutting the fastener from the fabric, the united part thereof being at about the middle of the fastener, substantially as set forth.
