To all whom it may concern.-

Be it known that I, WILLIAM W. MoCALLIP, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for IVeaving and Selvaging Diamond-Mesh Wire Fabric; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for weaving wire fabric of the kind known as diamond-mesh, because the diagonals of the mesh stand in the direction of the length and width of the fabric although the mesh may, in fact, be of square form.

In the particular kind of machine to which the present invention relates there is a frame containing two angularly-arranged pairs of parallel rotary shafts, each pair carrying fingers or teeth adapted as the shafts are revolved to elevate and depress alternate wires to form sheds through which the weft-wires are inserted, the fabric being intermittently moved from the position where every other wire israised to a position where said wires are depressed to successively form new sheds into which the weft-wires are inserted to'make the fabric.

The present invention consists, first, in the provision of improved devices for guiding the wires inserted to manufacture the fabric; second, in improved means for feeding and holding the fabric in proper position while being woven; third, in improved means for beating up or forcing into proper position in the fabric the weft-wires; fourth, in the provision of an improved wire elevator and depressors adapted to reach wires that have passed beyond the range of the regular elevators and depressors so that the fabric will be properly woven at its edge as well as in the body thereof; fifth, in improved devices for reeling or rolling up the fabric as it comes from the weaving-machine, and, sixth, in the provision of means for making a selvage in the fabric.

In the accompanying drawings, Figure 1 is a general plan view of the machine, some parts being omitted. Fig. 2 is an elevational view of the right-hand side of the machine,

some parts being omitted. Fig. 2 is a detail in perspective of the shed-forming and beating-up devices. Fig. 3 is a vertical sectional view on the line a a, Fig. 1, to show the wireguiding and beating-up devices. Fig. 4 is an elevation of the same viewed from the fabric side. Fig. 5 is a plan view on a larger scale than appears in Fig. 1 of the selvage-applying mechanism. Fig. 6 is an elevation of the same viewed from the fabric side. Fig. 7 is a vertical section on the line a n, Fig. 6, looking to the right. Fig. 8 is a section on the line to 20, Fig. 6, showing the wire-bender looking to the right. Fig. 9 is a side View of the rack and pinion for operating the bender shown in Fig. 8. Fig. 10 is a sectional view illustrating in edge view the improved elevators and depressors. Fig. 11 is a plan view of the same, and Fig. 12 is an elevational view showing the fabric reeling or rolling devices.

Like characters of reference in the several views designate corresponding parts.

1 designates an upper eccentric-shaft, to which is hung and by which is operated a bar 2 to contain the wire-depressing fingers 3, and 1 designates a similar shaft, to which is attached a bar 2, containing wire-elevating teeth 3. The two shafts l and 1 are connected by a sprocket-chain 1", (see Fig. 2,) and all four of the shafts are driven from a belt-wheel 1, (see Fig. 1.) operating the shaft 1, the latter having miter-gears engaging similar gears on the shaft 1. There are. as before indicated, two pairs of shafts 1 and 1, each pair operating two sets or series of teeth, the shafts being arranged at right angles to each other, as indicated in Fig. 1, so that as the fabric is moved in .the process of Weaving each of two series of alternate wires at each side of the fabric is first elevated and then depressed to form a shed, through which the strands that go to make up the fabric are inserted. The teeth for elevating and depressing the wires are shown herein to be of the hollow varietythat is, provided with a horizontal strand-guiding eye open at one side and toward the fabric. T o prevent the strandwire being inserted from turning aside out of its path through said eyes, I provide several or all of the eyes with beards or covers shaped like a sector of the body of the guiding-eye yieldingly held over the openings at the sides.

The beards are designated a. (see Figs. 3 and 4,) and they can be mounted on a red at, hinged in ears 4c" on the bars 2 and 2. A spring at is provided to hold the beards against the openings of the strand-guiding eyes, so that as the fabric is fed the beards will yield and allow the fabric to pass to its next position. After a pair of wires is inserted the whole body of the fabric is fed or moved to a new position. To properly effect this, I now provide fabric-moving devices consisting of wheels or rollers of the kind indicated at 5, having their peripheries furnished with pyramidal projections 5, adapted to {it in the mesh of the fabric, said fabric-feeding wheels or rollers being mounted on a main intermittently-driven shaft 6 and auxiliary shafts 6*, connected with and driven by the main shaft through sprocket-chains or other gearing. The main shaft 6 is intermittently driven by the eccentric-shafts 1, appropriate and well understood gearing being interposed for effecting such in termittent motion. 1 have discovered that it is particularly important that the fabric within the angle between the shafts 1 be held from distention laterally or longitudinally, otherwise there is likely to be irregularity in the weaving and buckling of the fabric. Hence 1 locate one or more of the wheels or rollers 5 within said angle, as seen in Fig. 1.

The improved means for moving or beating up the inserted wires consists of a beaterarm 7, secured to a shaft- 7, journaled in brackets 7, projecting from the side of the bar 2. Keyed to said shaft 7 is a tappetarm 7 and a tappet-arm '7, projecting in opposite directions from the shaft. The tappetarm 7 is operated by a crank-arm 7 on the shaft 1 to throw the beater-arm 7 inward toward the fabric, and thus move or beat the inserted or weft wire up ,to its proper position in the fabric. \Vhen the crank-arm 7 has passed the tappet-arm 7, the bar 2 is drawn downward by the operation of the eocentric-shaft and the tappet-arm 7 brought against the upper end of the bar 7, thus returning the beater to its original position between the teeth.

I have further discovered that itwill some times happen that the wires along the edge of the fabric are not regularly interwoven. This is because the wire elevating and depressing teeth as heretofore constructed do not reach the ends of the wires after they pass to a point out of the vertical plane of the bars 2 and 2. This point I have indicated at A, Fig. 1. To reach such wires, I

These added and they are with wire-bending tongues 10.

preferably composed of two parts, a shank and a blade, the shank being attached to the bars 2 and 2 and the blades adjustable horizontally on the shanks at right angles to said bars, so that the operative ends may be set to act at the most favorable points on the wires to depress and elevate them. This adjustability of the teeth 3" ant 3" is advantageous because the fabric to be woven will vary in the size of mesh as well as in tlie strength and character of wire used.

As fast as the fabric is woven it is important that it be properly reeled or rolled up, so I propose to provide at the rear of the machine a frame 8, containing a shaft 8, having thereon rollers like the rolls 5 for en gaging the mesh at the under side of the fabric as it comes from the machine, and a parallel shaft 8", containing a plane roller 8, yieldingly held by a spring 8 against the inner side of the cylinder of fabric. To keep the roll or cylinder of fabric from falling over,1 provide a roller 9, journaled in a frame havingside bars 9" pivoted at 9 to the side of the frame 8 and having suitable means for holding it in position.

o come now to the apparatus for apply ing a selvage to the fabric. This apparatus comprises, generally stated, first, means for taking a pair of the crossed ends of two wires at the edge of the fabric and bending them horizontally, so that they stand parallel to each other; second, means for bending them upward and inward over the selvage wire, and,third, means forlooping or clenching them down around the selvage wire.

Referring to Figs. 5 and 6, the character 10 designates a frame which is adjustably secured to and reciprocated with the bar 2, and 11 designates a frame that is similarly secured to and reciprocated with the bar 2". These two frames are arranged on the bars 2 and 2, so that they stand in approximately the vertical plane of the edge of the fabric as it progresses through the machine, as indicated in Fig. 1. On the inner face of the frame 10 are two symmetrically-shaped sliding plates 10, having their lower ends formed The plates 10" are connected by links 1O with the opposite sides of a disk 10, centrally journaled in the frame 10. The outer end of the journal of the disk 1O has secured to it a crankarm 10'', that is intermittently struck by the cam or inclined end 1 of an arm 1 on the shaft 1, so that the wire-bending tongues 1O are brought toward each other to bend the ends of the wires together. A spring 10*" between the sliding plates 10 will serve to separate the tongues after the cam 1 has passed the crank-arm 10". During this bending operation the wires in the body of the fabric are kept rigid by means of a grooved vise member 10*, working in conjunction with a similarly-grooved vise member 11 on the frame 11. *hen the tongues 1O are descending into place on each side ofa pair of crossed ends of wires, a bending-finger 11 on a shaft 11", journaled in the frame 11, is given a partial rotation by a rack-bar 10 on the frame 10, turning a pinion 11 on the shaft 11 This finger 11 turns the paralleled ends of the wires up into a position, as seen in Fig. 8, where they can be bent down around the selvage-wire 12 by means of a vertically-acting die 10 working in conjunction with a bed member 11 on the frame 10. It will be observed that each of these operations takes place during a single revolution of the shafts 1 and 1.

The operation briefly is as follows: For convenience in practice, a small piece of fabric for a starter is firstmade up by hand. This piece is put into the machine so that the longer unwoven ends lie alternately under the teeth 3 and above the teeth 3. With the wires so placed and the eccentrics of the shafts 1 and 1" in the position seen in Fig. 3, a shed is formed through which new strands are inserted by the attendant. By the application of power the shafts 1 and 1 are then each given a complete revolution, during which the several operations hereinbefore' referred to are performed. The beating-up operation and the operation of the benders 1O at the selvage take place first-that is, during the first portion of the revolution of the shafts 1 and 1. The fabric-feeding operation follows these operations or while the bars 2 and 2 are sufficiently separated from each other to allow free movement of the fabric. hen the bars 2 and 22 approach each otlier-that is, during the final portion of the revolution of the shafts 1 and 1-the bending-up and the bending-down operations at the selvage take place and new shed formed.

Modifications in the forms of the parts shown and described can be made without departing from the substance of the invention.
