SPECIFICATION forming part of Letters Patent No. 717,207, dated December 30, 1902.

Application liled March 22,1902. Serial No. 991390- (NO modem i T all whom it may concern.-

Be it knownthat I, CHARLES W. JAMES, a

.citizen of the United States, and a resident of the city and countyof Philadelphia, Stat-e of Pennsylvania, have invented certain new and useful Improvements in Wire-Weaving Machines, of which the following is a specilication.

My invention relates to improvements in.

jects of my invention are,rst, to furnish a machine which will crimp the consecutive warpwires in alternately opposite directions and pass through the loops thus formed the weftwires; second, to furnish means for flattening the warp-wires downupon the weft-wires after the latterhave been passed through the loops in the former; third, to furnish automatic means for feeding the' warp-wires step by step to the bending and attening dies; fourth, to furnish means for feeding the weftwires through the loops formed by the bending-dies in the warp-wires while the warpwires are still held by the dies; fifth, to furnish means for shearing 0E theweft-wires after being passed through the warp-wires,

and, sixth, to furnish certain other details, which will be hereinafter fully described.

In the accompanying drawings, forming part of this specification, and in which similar characters of reference indicate similar parts 'throughout the several views, Figure 1 is a front elevation of my wire-weaving machine; Fig. 2, an end elevation of Fig. 1; Fig. 3, a section of Fig. l on line A B; Fig. 4, a detached sectional view of the wire-bending dies; Fig. 5, a front elevation of the lower part 'of the machine, the feeding-rolls being removed; Fig. 6, a front elevation of the machine, the feed-rolls and the lift-bar being removed, showing the looping and cutting-off dies; Fig. 7, an end elevation of the cuttingo dies; Fig. 8, a view of the feedrol1s', some in elevation and some in section; Fig. 9, an enlarged end elevation, partly in section, of

the meanslfor feeding in the cross or weft wires; Fig. 10, a section of Fig. 9 on line C D. o isa bed-plate, forming the stationary head of the machine, to which are bolted the vis carried in guides e, carried by the sides() ZJ of the frame. The movable head d carries the movable portion f of the wire-bending dies and the movable portion g of the flattening 'dies, both of which will be fully de scribed hereinafter.

The movable head d is caused to reciprocate as follows: 71., Fig. l, is a pinion carried on a shaft e', which carries and is d-riven by a pulley j, which is driven by a belt (not shown) from any suitable source of power. 7c is a bracket bolted to bed a or frameb, which carries shaft The gear h meshes with and drives a gear Z, which is fast to and drives a shaft m, which carries a cam fn, adapted to engage a friction-roller o, carried loosely on shaft n, which is carried by movable head d. p represents nprights carried by head d, carrying at their upper ends yokes r, which carry a shaft s, Fig. 3, parallel with shaft m, which carries a friction-roller t. As the shaft m is revolved the cam n alternately'engages rollers o and t. When it engages the former, it depresses head d. When it engages the latter, it raises this head. The cam n is so shaped that it will after lowering the movable head hold this head for some time in its low- -est position and will after raising the head hold it for some time in its highest position to permit other parts of the machine to d'o their work at these times. V

The ends u. of the shaft upon which roller o is carried are arranged eccentrically to the portion which carries the roller and are car` 'ried in bearings fu, carried by the head d.

One of the ends of the shaft is furnished with teeth w, which gear with a worm w, carried by a shaft fy, carried by head d. .c is a hand-wheel, by means of which shaf y and shaft u may be rotated in order to lift or lower the roller o4 to decrease or increase the throw of the head d.

As the cam n is rotated its irregular form causes the distance between the shafts uand s to vary, and in order 'to permit this variation I interpose between the heads of the upacross the front of the machine,

. lin bearingsl9 10, carried by frame b. The

feed-rollers are intermittently rotated, being driven when the bending-dies are separated and being still when these dies are closed.

The means for. actuating the feed-rollers are as follows: 11, Figs. 1 and 2, is a cam carried by and rotating with the shaft m, which is adapted to engage and depress a slide 12, which is connected to an arm 13, pivoted at 14to the frame b. 15 is a link, the upper end of which isfconnected at 16 with the free end of arm 13 and the lower end of which forms or carries appawl 17, adapted to engage with a ratchet 18, fast upon the upper feed-rollercarrying shaft 7. the cam 1,1 engages and depresses arm 13, which depresses link 15, causing the pawl17 to rotate the ratchet 18 and shaft 7. 19 is a pawl engaging ratchet 18 verse movement thereof. 2() is 4a spring for returning slide 12, arm 13, link 15, and pawl 17 to their raised positions after the passage of cam 11. 21 is a slot in arm 13, which permits an adjustment of the slide l2 in order to -cause the camll, through the arms, link,

and. pawl, to `cause a greater or less movement of ratchet 18, as may be desired. 22, Fig. 1, is a which gears with a gear-wheel 23, of similar pitch, upon` the shaft `8, through which the two shafts are caused to be rotated simultaneously. y

' The feed-rolls (best shown in Figs. 3 and 8) consist of hubs 24, secured to'shafts 7 8 by set-screws 25 and of loose collars 26, carried by the hubs, Y being staggered, so that each collar upon one shaft is' held .between two others -upoirthe other shaft, and vice versa, as shownin Figs. 1 and 8. The ledges of the hubs 24' are chamfered 0E, as shown, so as to form a groove to receive the warp-wires 3 4,l upon the other sides of which rest -the collars 26, as shown.

After leaving the feed-rollers and before passing to the bending-dies the warp-wires pass through a lift-plate 27, Figs. 3 and 5, which .is'carried by guides' 28, carried by the mov. .able head d;

'.2 29 repesents stops carried by guides 28 for lifting or depressing the lift-plates, and 30 Y f stops carried by base-plate a,

warp-wires have been fed inl by the feed-rollers and the movable lift-plate rests when As the shaft gm revolves.

to prevent a re' .upon and turning :with

Aslide 51 is depressed gear-wheel fast upon shaft 7,.

the collars upon the two shaftsy head d lowered, the dies f2 will have bent the warp-wires 3 4 one up, the next down, the next up, the next down, and so on, forming in one wire a'n upward loop and in the next one a downward loop directly opposite the first loop7 all the warp-wires being bent in a similar manner. The dies f2 are furnished with openings or grooves 31, (best shown in Fig. 4,) through which the weft or cross wires 32 are passed while the dies are closed.-

When the dies f2 are closed, the sprocketwheel 33, Figs. 1 and` 2, carried by shaft m through chain 34, drives sprocket 35, upon the shaft 36 of which is a bevel-gear 37, which drivesa bevel-gear of which is a gear-wheel 40, Figs. 2 and 9, which gears with and drives a gear 4l, fast to a shaft 42, carried in bearings 43, carried by the frame b. 44 is a anged pulley, carried by'and turning with shaft 42, 45 a presserwheel loose .upon shaft 39 and driven by pins 46, carried by gear 40. The pins 46 enter holes 47 in the end ofthe presser-wheel 45, which holes are of. somewhat greater diameter than the pins 46.

48 is a movable friction-wheel carried upon a shaft 49, one end of which is loosely pivoted at 50 to the frame b, and the'other end of which is carried by a slide 51, the upper end of which is adapted to be engaged and moved downward by a cam 52, Figs. 1 and 2, carried shaft m. When the by cam 52, the roller 48 is caused to' bear -upon presser-wheel 45, which is lowered so as to bear firmly against the weft-wires 32, which are then by the presser-M1145 and the rpulley 44 driven in through the dies f2 and between the loops formed on the wires by these dies'.- The camr 52 is made in two pieces 53 54, which may be shifted around on thel shaft so as to increase or decreaseits operative face in order to cau'se the feeding of the weft-wires to be longer or shorter as may be necessary for different widths of cloth. f

The general operation of the machine is a." follows: Supposing'the movable head to be lifted and the dies opened, the warp-wire feed-rollsl 5 Gare rotated through the mechanism driven by shaft m through cam 11, as previouslyA described, and the warp-wires which are now lifted clear of the lower dies by the lift-bar 27 and the fabric already woven,are moved the proper distance inward. The movable head d is now moved dow'n, the dies j"2 engaging and bending the warp-wires and the flattening-dies g3. flattening outthat portion of the fabric that is between them.

38, fast upon the shaft 39 IOO After the warp-wires have been bent the dies are kept closed for some little time, owing to the form of the operating-cam n, and during frame b, and thenthrough the perforations 31,.for`rned partly in the upper and partly in' ner end of the-dies or guides 55.

the lower wire-bending dies' f2, and through the loops formed in the Warp-wires'by the dies. The cam 52 is set so as to feed the weft-wires across the entire series of warp-wires, which may extend completely across the machine or only part way, depending upon the width of the fabric being woven. After the weft-Wires have'been passed through themachine the movable head is lifted, and as it rises it carries up with it the Glitter 56, Figs. 5, 6, andt 7, which shears off the weft-wires at The in- As soon as the movable head is fully raised the warpwire feed-rolls 6 are again operated, and the warps are again fed in. l The machine is particularly adapted for weaving heavy wires, which -may be of any desired cross-section.

In Vorder that the feeding-rolls for the warpwires-.may be selfadjusting for different thicknesses of wire, the screws 25, that secure their hubs 24 to the shafts, pass vinto longitudinal slots in' these latter, (best shown in Fig. 8,) and atl one or both ends of the shafts are springs 61, of rnbberorother Silitable material, Which normally tend to lclose the hubs against one another, but which permit them to move apart to'adjust themselves to wires of different diameters. l62 represents collars fast to shafts 7 8, which hold the outer ends of the springs 61 firmly.
