METHOD' oF WEAVING wlRE.

SPECIFICATION forming part 0f Letters Patent N0. 692,407, dated February 4, 1902. Application filed May 9, 1901. Serial No. 59.414. (No specimens.)

To all whom, t may concern:

Be it known that I, WILLIAM J. WRIGHT, a citizen of the United States, residing at Pitts burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Methods of Veaving IVire, of which the following is aspecification, reference being had therein to the accompanying drawings, forming part of this specilication, in which- Figure lis a plan view of a number of spindles and spiral ceiling-guides assembled in proper relation to produce a continuous woven fabric and showing the same in course of construction. Fig. 2 isa cross-sectional View taken on the line II II of Fig. l. Fig. 3 is a similar view at right angles on the line III III of Fig. l, showing the coiling-guide and also the feed-rollers. Fig. 4 is a view of several pairs of interwoven coils as they are delivered from their spindles -with the intervening interwoven supplemental connecting-coil. Fig. 5 is a similar view, but showing all of the coils equally arranged. Fig. 6 is an enlarged detail sectional view of one of the spindles and guides.

Myinvention consists of an improved method of weaving wire into a fabric or netting by means ofinteritting spiral coils, whereby t-he full width desired may be made at one time of any desired number of wires simultaneously and continuously and in one operation. Heretofore in making wirework of this description it has been the practice to form but two intertting spiral coils upon a forming-spindle and then join each one of such pairs of interwoven coils by a single interwoven separate coil with the next adjacent coil of another similar pair, repeating such operation until the required width was obtained.

In the practice of myinvention a plurality v of spindles 2, having the usual spiral grooves 3 8, are mounted in suitable housings 4 at such a distance apart as will admit of the location between the spindles of separate guides 5, which for approximately the full length of the spindles are straight. These guides have in one side a groove 6 of sufficient size to admit the wire, but partly closed, so as not to allow the wire to escape outwardly, and at or above the delivery end of the spindles each of these guides is formed into a spiral 7 of the same pitch and relative position as the spiral grooves 8 of the spindles, the groove 6 55 thereof being maintained on the inner side, as shown. By reason of the close arrangement of the pairs of spirals to the next adjacent pair it will be seen that the spiral guide 7 may be looped through the alternate oppo- 6o site spiral loops of such pairs without interference with the forward progress of the coils, whereby when the independent spiral coils 8 are finally delivered from the ends of the guides 7 they will travel forward in the same 65 relation to the coils 9 10 from the spindles 2 and will interengage with such coils. By reason of the close proximity of each independent pair 9 lO to the next adjacent pair sufficient clearance is allowed for free en- 7o gagement and interaction, and it will be seen that such assemblage and interaction of the coils wili be continuous throughout the operation. As delivered from the spindles and spiral guides the interwoven coils will assume 7 5 the arrangement and relation to each other shown in Fig. 4 of the drawings, while after having been subjected to an equal tension all over the coils will be symmetrically arranged, as shown in Fig. 5. 8o

The forward feed of the wires is accomplished by means of the customary feed-rolls ll, and it will be understood that such other details of construction necessary to embody the invention in practical form in an operative mechanism are properly Within the province of the designing engineer or are the subjects of other inventions and do not necessarily form essential parts of the present invention.

It will be understood that such wires as are' referred to by the term adjacent are those wires which in the completed fabric lie adjacent to each other and are connected by the additional wire, or, in other words, the adja- 95 cent wires 9 9, Woven by any two adjacent spindles 2 2 and are connected by the independent coil S, formed on the ceiling-guide 5 and its spiral terminal 7.

It will be understood that several wires may roo be passed through or around the same groove so as to, in effect, form one Wire, and Wherever the term coil or other synonymous term is employed it is intended to include such plural wires. It Will also be understood that the fabric may be Woven in flat form, as in making mattresses, or that the spindles and guides may be arranged in cylindrical form, so as to Weave bags or similar articles.

Having described my invention, what I claim isl. The method of making wire fabric consisting in simultaneously forming pairs of interwoven spiral coils and independently forming intervening connecting-coils between such pairs, substantially as set forth.

2. The method of making Wire fabric consisting in simultaneously forming pairs of interwoven spiral coils and independently forming intervening coils and alternately engaging the same with the adjacent members of the pairs, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
