The p ates 25 and 27 have the slots 29, and they are secured to the plates 20 and 21 by screws 30 extending through these'slots. By moving the plates 25 and 27 on the screws, the distance bet-ween the pins 26 and 28 may be varied so as to vary the width of the niateria The shuttles 31 are driven in the race ways 22 and 23.

The projections 38 extend from 4 5 the frame 37, and the roller 39 is journaled'i between-these projections on the pin 39. A plate 40 is also secured to the frame,and when the shuttle is in place it is in contact with the rear surface of the plates 10, 20, 21 A late 4-1 the front faces of the same plates adjacent to the race ways. The plates. 40 and 41 are of somewhat greater width than the race ways, so that the shuttles are held in place by them. Distance ieces 42 aresecured between the plates, anc these are of such length relatively to the thicknessof the plates 10, and 21 as to permit the plates 40 and 41 plates. Rollers 43 are journaled between the plates, and are of such diameterrelatively to the distance pieces as to engage the surfaces of the race-ways and relieve friction. The wire extends from the spool through the openings 44 in the plates 40 and .1 under the tension late 45 through the uide 46 to the coil The guide 46 has the extension 47 secured to the plate 41. A screw 48 extends from this extension and adjustment nut 41-9 is arranged on the screw, so that the tension may be varied. The guide 46 has the rounded surface, as clearly shown in Fig.

10, over which the wire runs as it extends laterally from the shuttle when put under strain as shown in Fig. 3. 'It will be noted that the wire runs slack except as the shuttles pass the extremeportion of the race way (position shown in Fig.-

Here the strain on the wireis suflicient to'give' the coils some 50 form this fabric the shuttles must traverse one of the race-ways, and return so as to lay its wire directly upon itself, and the wire of the other shuttle passes from one coil to another by its action in the opposite race way.

As shown in Fig. 3 the mechanism drlving the shuttle of the race way 22 is speeded exactly twice that. ofthe shuttle in the race way 23.

'For convenienceof description I will designate the shuttle 31 in the race-way 22 (see Fig. 3) as the first shuttle. and the shuttle 31 in the race-way 23 as the second shuttle. Starting with the position shown in Fi 3, the first shuttle will be driven out of the race way 22 into the part 23 of the race-way 2;} by the time the second shuttle reaches the tie traveling in the race way 22 twice as fast as the shuttle in the race way will travel the half revolution, while the second shuttle is traveling one fourth of the revolution. i The first shuttle remains in the part 23 dist engaged by anydriving mechanism until the second shuttle has been driven out of the race way 23 into the race wa'y 22, when the driving mechanism which has been operatmg upon the second shuttle. picks up the first it along the race way 23. This second shuttle will then be driven around the race way and into the part 23 of. the race way 23 before first shuttle has completed its travel through the race way 23, and the wire top of the race way that is, the first shut-' shuttle by its continued movement and forces I l l carried by this second shuttle will cross itself in contact as the shuttle passes from the race way 22 to the race way 23, and thisis true in each instance with relation to the wire The wire carried by the shuttle Tn the race way 23 passes from one loop to another as the shuttle passes from the race way 22 to the race way 23, the wire at this crossing not being in contact with itself,'but in contact with the preceding loop. By thus varying the r-elation of loops, that is, crossing-the wire in contact as the shuttle moves from the raceway 22 to the race way 23, and jumping from one loop to the next when the shuttle passes from the race way 23 to the race way 22. such a relation is given to the loops one carried by a shuttle traversing the race way to the other, that the wire when flattened p out forms the interlock at one side as shown at 125 in Fig. 12-, and the overlap as shown at 126 insaid figure. It will be understood, however that generically considered, this specific relation of the loops may bevarieddepending on the timing and speeding of the driving mechanism acting on the shuttles in the race ways. It will be noted that the axis of the coils formed'on the pins is at right angles to the plane in which the shuttles travel,

and that the fabric as it is forced ofl'the pins is in the form of a series of figure Bjcjoils in close contact whose axes are lengthwise of the fabric.

The driving mechanism for the shuttle is as follows:Gear 50 is ournaled on the shaft 14; and is driven by gear 51 011 the driving shaft 5. The gear 50 drives the gear 52 which is journaled on the shaft 13. A

driver 53 is fixed on the gear 52, and is shaped to engage the roller 39 on the shuttle, and to drive the shuttle through this engagement. A similar driver 54 is fixed on the gear 50. The driver 53 drives the shuttle through the race way 22, and the driver 54 through the race way 23.and these drivers are simply arms carried on the hubs of the gears 50 and 52, and are of such length that their ends will engage the rollers 39 on the 13:

, coils from a direction "fact that it is always in a downward direction, so that it is assisted bygravity as Well -as the momentum of the shuttle. The driver 53 alternately drives a bobbin one revolution and runs idle one revolution, so that al- 5'3, travels twice as fast as lution. As each succeeding coil ismade, the wire forming it is drawn in back of the preceding coil, so asto force the fabric made up of the preceding coils off from the pins 26 and 528. It then moves intoa guide way, the bottom of which forms an anvil 55 for'the ham vidcd with a stationaryside 56 and a movable front face. of a slide plate 59. The rear end of this plate is guided by the pins 60 and the front of the slide rests on'the anvil, and is secured by the screw 61 which extends through the slot 62. The hammer is carried.

64 by means of a pin 67. The rod termi- -nates in an eccentric strap 69 which operates upon the eccentric 70. Theeccentric is fixed on the driving shaft 5. With each revolution of the driving shaft,.therefore, the

hammer is depressed and engage'sand'flattensthe coils fez-med on the pins. Followingthe operation of this mechanism, the ec-' centric 70 on the drive shaft reciprocates the link 68. (See Fig. 1). Thelink 68 or con necting rod is pivotally connected by means of the bolt 67 withthe lever 64 and through the connection reciprocates the lever 64. The hammer plate 58 'andconsequently the hammer is reciprocated with the lever 64, (see Figs. 4? and 1). It will be noted thatthe flattening process changes the axis of the lengthwise of the fabric to a direction approaching'a. right angle to the general plane of the fabric.

Itis desirable that the sides of the fabric be engaged as it isdepressed or flattened so straight. To accomplish this a bracket 71 is secured to thehammer plate 58*. A rod 72 extends through this bracket and adjusting nuts 73 arearranged above and below it so that the rod may be adjusted. The-bellcrank lever 74 is pivoted on the bracket 76. The bracket 76 is formed by a projection The movable side is formed by the is pivotally connected with a to the lever fabric.

I from the bracket '77, and the bracket 77'is secured to and extends forwardly from'the plate 10. The upperarm of the bell-crank lever extends through a perforation 81' (see Fig. 2). It will be readily seen that as the hammer descends the side wardly through the action ofthejbell-crank lever. The fabric inthis stage ofits development will have its coilsclose togethenin longitudinal direction, and for most fa'brics it. is desirable to lengthen it. A'device for this i's 'shown in detail in Figs..5, 6 and 7.;

57 is pushed in It is in'position to receive the fabric as it comes fromthe' flattening hammer, and ust as the fabric is engaged by thhammer, and length ens or stretches itwhile the'fabric is in the grip of the hammer. Thislengthening mechanism and the. succeeding mechanisms cooperating on the fabric are supportedby, a plate 78 which extends longitudinallyfof themachine; One end of this is supported by a bracket 77; and the other in any. convenient manner not shown. guide plate .82 isbent around the plate 78, the sides beinglbrought up and having an inwardly extending edge 83. A slide 84 moves in the guidethus' formed. It is proplate so; a

vided' with a slot 85 through-which the fabric passes. The clamping finger 86 is pivoted onthe bl0ck 84 y means of a pin 88.

Therod 99 terminates in mod 99 is an eccentricstrap which is operated upon by the eccentric 101. This eccentric is so timed with relation to the'eccentric 70 that the arm shown'inand the finger 86 forward while the hammer is up, and this action is reversed so that the wire is gri ped by the finger justas the wire has been ward the rightby the arm 93 throws the arm 89 and with it theblock 84 and finger 86 toward the right, and this carries with it the fabric, lengthening device works with great accuracy with-relation to the-number of coils,

instance. As this occurs,the wire forming the span is forced between the blades 25 and 27. and the bottom of. the preceding coil, thus forcing the bottom of the preceding coil outwardly, and this twists the trans verse portion extending from the bottom of this coil. There would, of course, be a neutralizingtwist in the transverse portion extending from the top of the same coil were it not for the fact that this transverse portion continues to the shuttle, so that this long span of wire takes up the twist without appreciably affecting the transverse portion. In each instance, therefore, the bottom of the coil being forced outwardly, the transverse portion is twisted so as to give the re sulting fabric a tendency to curl upwardly or toward the top. If the direction of movement of the shuttles were forced so that the tension on the span of wire would be taken up at the'top instead of at the bottom, this tendency would of course be reversed;

. The torsional elastic limit of wire is in creased by giving itan initial twist beyond its elastic limit. For example, if a wire is twisted slightly beyond its elastic limit, it will be found that its torsional, elastic limit in the direction that it has been twisted has been increased, while its torsional elastic limit in the opposite direction is decreased. For some uses stays are subjected to very sharp bends in one-direction so that it is very desirable to have them able to stand these bends without taking a permanent set,

while at the same time,- iiexure in the opposite direction is not so great. Where this is the case, giving to the stay an initial twistv in the transverse portion, thus increasing its resistance to a permanent set in that direction, is therefore desirable. The present machine is capable of doing this, not only with a single wire but of coiling a fabric with this initial'twist and at the same time associating a plurality of wires. Of course, as the stay is forced oft of the coiling pins, it has a tendency to curl up. To avoid this I have The anvil'102 of this forming hammer is carried by the plate 78 and is convex longitudinally of the plate, that is. has its axis across the fabric and parallel to its plane. hammer 103 (see Figs. 1 and 11) is similarly faced. so that the fabric is given a set in a direction reverse to that in which it. has a tendency to coil, and the result is that the fabric after passing the forming hammer will normally lie in alinement. The hammer is carried by the hammer plate 104, and this plate extends through a guide formed by an extension 105, on the bracket 63 and also The extends through a guide lbs. This guide is supported by a cross iece 107 extending across the maphine. s cc Figs. 1 and 4). A lever 108 is pivotal y secured by'mea'ns of a pin 111 on a lug 110 extending from I the bar 107. The pin 67 extends through I the end of the lever 108 so that the lever is operated by the eccentric 70. It will be noted, however, that the lever 108 is fullever 74 is fulcrumed at its end, so that the hammers 108 and 58 alternate in their movement. In this way the hammer 103 is in its upper position as the fabric is pulled out by the lengthening device.

It is also desirable with some fabrics to tion, and this can be accomplished by shaping the faces of the anvil 102 and hammer 103 as shown, and these faces are not only curved longitudinally, but also laterally for this purpose. This lateral curving of the face of the anvil and hammer is clearly shown in Fig. 11.

The fabric after leaving the hammer 103 passes through a guide 112, and then between the rolls 113 and 11%. These rolls are sion. The wheel 1121 is journaled on a shaft 116, and this shaft 116 is slidingly mounted on-the pins 117. The pins extend upwardly from the plates 78 Springs 118 are tensioned against the shaft 116 and nuts 119 are screwed onto the pins 117, so as to varyon the shaft 115 and is intermittently driven forward asthe machine operates, A link 121 is pivotally secured to the hammer plate 104. It is pivotally connected with a block 122, and the block 122 is pivotally mounted on the arm 123, the arm being journaled on the shaft 115. The block 122 is so shaped relatively'to the wheel 120 as to engage it as the rod 121 is pulled upwardly, and thus carry the wheel 120 with it, and on the downward stroke of the hammer, the block releases the wheel 120 and permits the block to move over the surface, so as to engage a guide wa; F0 iiiitten the fabric.
