- the three essentially-identical twisting-mechanisms are for twisting the cordstrands 28, 28, 21 and 28 of the three tapes 20 which are. made simultaneously. Therefore, only one 'of the three shafts, namely, shaft 88 and A collar ill -(Fig. 8) isflrmly secured to the tubular shaft 88 by a set-screw I I, and screws 12 (Fig. 8, only one of which is .shown) secure a table 13 to the collar 10.

will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over theprior art.
In the description and claims, the various parts and' st'eps are identified' by specific terms for convenience, but they are intended to be as generic in their application as the priorart will permit.

Fig. 17 is a front elevation of one of the three identical cord-strand removing-and-shedding members; and
Fig. 18 is a front identical cord-strand shedding-hooks.
Referring 'to'the drawings, Figs. 1 to 3 illus-' trate a corded tape 20 which can be manufactured on the machine of the present invention. The tape it includes a relatively-thin tape-body 7 2! formed of longitudinal warp-strands 22 inter- Y woven with transverse weft strands or weft picks 23, and'includes a relatively-thick twisted cord .25 formed of a plurality of. twisted cord- strands 25, 2t, 21 and 28, with the weft strands 23 woven transversely between certain of the twisted cordstrands as shown.
The main portion of the machine may be constructed in accordance with any one of a number of different types of weaving looms or machines modified in. accordance with applicants invention. The particular machine 29, schematically illustrated in the drawings, is adapted to simul- Fig. 3 is a transverse sectional view takenpn the line 3-3 of Fig. 2;

andincludes a main drive-shaft m, which by means of cranks 3t, and driving-rods 32 pivoted at 33 to the batten 3t, oscillates the batten about its pivot 35 (Fig. 5). The drive-shaft 30 also, through any suitable shuttle movement or mechanism 36, including the fiexiblestrap 31 which actuates any suitable operating mechanism mounted in the shuttle-box 38 secured on the front of the batten 36, serves to actuate the three positions, while permitting the cord-strands to shuttles 39 in any suitable way well known to v those skilled in. the art. v
The main drive-shaft 30 also serves todrive any suitable shedding movement 40 through gears and shafts M, 52, 43, M, 45 and 66' for actuating the harness-frames 41, 8.8 and 69. A harness Y frame 50 is. mounted to be stationary. Each of the two hamessdrames 41 and 48 has a plurality of heddles 5i which accomplishes the shedding of the warp strands 22 in a usual way well known to those skilled in the art. And each of the harness-frames 41 and. is provided with three large spaces tree of heddles, so as to provide ample space for the three sets of cord- strands 25, 28, v 21 and 28 of the three tapes being'made.
to extend through without hindrance totheir elevation .of one of the three shown in the fragmental drawing of each of the frames l1, 88 in Fig. '7. The harness-frames it and 80 cooperate together to bring about the proper shedding of the twisted cord-strands 28,
28, 21 and 28 as will be hereinafter described. The frame 88 carries nothing butthree twisted cord-strand removing-and-shedding members 88 (only one being shown) and the stationary frame ll) carries nothing but three shedding-hooks 81 (only one being shown).
The warp strands 22 can be fed to the machine in any suitable way from any suitable means,
and in order to interfere as little as possible with the illustration of the remainder of the mechanism in Fig. 5, are shown as entering from the rear of the machine at the right side of Fig. 5
and passing over the loom-beam 58 and then through the spaces between the wires 84 of the back-reed or warp-guide 88, then one set of alternate warps passes through the eyes of the heddles M of harness-frame l8 and a second set of :the remaining alternatewarps passes through the'eyes of the heddles Ii of hamess-frame 81.
:then through the usual weft-packing reed 88 of the batten 84, then to the weaving-and-twisting point 88 where they are woven to form the three tape-bodies 2i of the three tapes 28, and then 7 close together. The three essentially-identical twisting-mechanisms are for twisting the cordstrands 28, 28, 21 and 28 of the three tapes 20 which are. made simultaneously. Therefore, only one 'of the three shafts, namely, shaft 88 and A collar ill -(Fig. 8) isflrmly secured to the tubular shaft 88 by a set-screw I I, and screws 12 (Fig. 8, only one of which is .shown) secure a table 13 to the collar 10. The table '18 rests upon a washer 18 which, in turn, is supported upon the frame cross-member 18. The hub 18 of the gear 88 is secured to the shaft 88 by the setscrew Tl. A cord-strandtwisting-head 18 has a collar 19 at its upper end which is firmly secured upon the lower end of the tubular shaft 85nd jacent the underside of the frame cross-member 88, by being threaded thereon and may be held in non-rotatable locked position in any given threaded position by means of a set-screw 8|. Four rods or bars 82 of the twisting-head. 18 are ilrmly connected to the collar to and flare downward to a head-plate 88 to which they are firmly secured.
Firmly secured to the table 18 arefour spoolholding pins 8!, on each of which is mounted a spool 8|. As the four cord- strands 28, 28; 21 and 28 of the cord 28 of one of the'tapes 2| are fed from the four spools 88 'in essentially-identical manner, only one of these cord-strands will be specifically described in its passage from a spool 88 to its position outside of the head- -plate 88.
assays-7 twisting movement, onLv one space 82 being- 88 of Fig. 8, passes through the eyelets 88 and 81 secured to the tubular shaft 88, then passes between the pair of strand-.tensioning frictiondisks 88, which latter disks are normally held adjustably pressed together by means of a coilspring 89 and nut 90, then passes through an eyelet 9| mounted in the tubular shaft 88, then passes downwardly through the tubular shaft 88 and through an eyelet 92 secured to'the headplate 83, then through an eyelet 93 carried in pass similarly downwadly through eyelets 8B in the head-plate '83 of the twisting-head l8 and then all four cord-strands pass forwardly through one of the three large open spaces 91 (Fig.- 6,
only one of which is shown) of the back-reed the parts it carries, will be specifically described.
80. The coil-springs 98 equalize the tension on each of the cord-strands so as to avoid excessive tension being placed on any of the cord-strands as the head-plate 83 rotates.
In making one of the tapes 20 illustrated in the drawings, the cord- strands 28, 28, 21. and 28 of such a tape are given one-quarter of a complete twist for every four picks of the weft strand 28. although it will be appreciated that a greater or less number of picks per quarter-twist could be employed. Thus, by observing Fig. 2 of the drawings, it will be seen that four picks are illustrated as passing transversely beneath the cord- strands 28 and 21, then four more picks pass beneath the cord- strands 28 and 28, and 'so on. Thus, for each complete cycle consisting of forward and back movement of the batten 88 in packing one pick, the two harness-frames l1 and 48 shift to their opposite positions to change the shedding of the alternate set of warps 22 to produce a simple basket-weave construction as illustrated in Figs. 2 and 3 of the drawings, although it will be appreciated that any other desired weave for the tape-body 2i may be accomplished by employing a suitable number of harness-frames and operating them at proper timing and sequence,
all as is well understood by those skilled in the art.
rotation of the twisting-head" in order to pro-.
duce the particular corded tape shown in the drawings. All weft picks pass transversely between the four cord-strands with two cordstrands above and two below each pick, although the angle of passage of the portions of the picks that extend between the cord-strands varies in successive picks of anygroup of four picksin accordance with the stresses which are present as the result of the twisting of the cord strands.
In order to at all times maintain a proper sheddin! of the cord-strands, so that two cord-strands are always in the upper shed and two in the lower Inasmuch as four weft picks are formed for shed when any pick is being formed by passage of the shuttle 39, special mechanism is employed as will presently be described. As will be seen from Fig. 50f the drawings, the head-plate 83 of the twisting-head I8 is at such a height above the horizontal plane through the weaving-and-twisting pointBQ, that the two strands 21 and 28 in .Fig. are in proper position in the upper shed without any mechanism being needed to move them to this upper shedded position, but merely as a result of the head-plate 83 being located well above the horizontal plane through the weavingand-twisting point 59. In order to shed the cord- . strands 25 and 26 and bring them into their lower shed position, the removing-and-shedding member 55 carried by the harness-frame 49, andthe shedding-hook 51 carried by the harness-frame so, are employed.
The shedding-hook 51 and harness-frame 50 are at all times stationary, as will be'seen from Figs. '11 to 16 illustrating successive stages of the shedding of the fourcord-strands. While four weft picks are being formed in the tape, the headplate 83 will rotate through the stages illustrated in Figs. 11 to 16 inclusive. The positions of rotaasea'ro'r tion illustrated in Figs.- 12, 13 and 14 each represent one-sixteenth of a rotation from the position shown in the preceding figure. The, position shown in Fig. 15 is a iurther one-thirty-second rotation from the position shown in Fig. 14, and
Fig. 16 represents a further one-thirty-secondro tation from that shown in Fig. 15. As stated heretofore, the shedding-hook 51 is permanently stationary and acts solely in the role of a hold-' ing-hook or -member to hold in a downwardlyshedded position such of the cord-strands as are brought beneath the hook-portion 98- of the shedding-hook 51 to engage the under surface 99 of the hook-portion 98. While the head-plate, 83. rotates through one-eighth of a rotation from the position of Fig. 11 to the position of Fig. 13, the member 58 temporarily remains stationary. By the time the head-plate 83 has rotated another one-sixteenth of a rotation to the position shown in Fig. 14, the member 58 has been raised to the per shedded position shown in Fig. 16, and also causes the strand 21 to he slid down along the sloping-surface I83 of the member 51 until it passes beyond the point I84 of the hook-portion I 98' and into engagement with the under surface 88 thereof.
I Now with the cord-strands 25' and 28 in the upper shed and the cord-strands 2B and 21 in the lower shed, four weft picks will have been interwoven across between thecord-strands as thus shedded, until the head-plate 83 has again rotated to a position corresponding to that illustrated in Fig. 13 and the member ti again goes through the cycle of operation from its position in Fig. 13 through the positions illustrated in Figs. 14 and 15 to itslowermost position in Fig.
16 in which latter position the strands 2! and 28 will be in the lower shed, and strands 25 and 28 will be in the upper shed, and so on for as long as the machine continues in operation to make the tape 20 having the twistedcord 24 as shown.
If it were to be desired to make corded tape in which the cord was formed of more cord-strands or less cord-strands than four, or in which there were more picks or less picks than four per quarter twist of the cord-strands, it will be obvious to those skilled in the art as to what changes would need to be made in the machine 29.
The invention may be carried out in other specific ways thanthose herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all y 1 changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
We claim:
l. A machine for making corded tape including: drive-means; cord-forming means driven by said drive-means and including arotary cordstrand twisting-head, and constructed and 'ar-' ranged to twist a plurality of longitudinal cordposition shown in Fig. 14, but this does not affect the individual strands so far as their efiective shedded position is concerned'because, while the rotation of the twisting-head 83 has caused the positions of the four strands to be shifted somewhat, the strands 21 and 28 are still in a suitable upper-shedded position, and when the member 56 moved up from its lower position in Fig. 13 to its upper position in Fig. 14, although it released the strands 25 and 26, they promptly engaged against the under surface 99 of ,the hook-portion 98 of the shedding-hook 51 so that the strands 25 and 2d are still held in their lower-shedded position.
But in view of the continued rotation of the head- 'plate 83, and the consequent rotation of the four eyelets 96 which form the anchor-points of the cord-strands as they pass through the eyelets 96 of the head-plate 83, the strand 21 isv finally shifted transversely of itself to a position near the member 56, so that as the member 56 now moves downward to the position shown in Fig. 15, the hook-surface I00 of theh'ook-portion "ii of memcord-strand from said shedding-hook and shift another cord-strand into-a shedding-position engagement with said shedding-hook.
and reciprocable means adapted to repeatedly shift a cord-strand into a shedding-position engagement with said shedding-hook.
3. A machine for making corded tape including: drive-means; cord-iorming'means driven by said drive-means and constructed and arranged to twist a plurality of longitudinal cord-strands into a relatively-thick cord extending longitudinall oi! the tape; weaving-means driven by said drive-means and constructed and arranged to interweave longitudinal warp strands and transverse weft strands into a relatively-thin tapebody, and weave at least some of said weft strands transversely between certain of said twisted cordstrands; a, shedding-hook adapted to hold a plurality of said cord-strands in a shedding position; means adapted to repeatedly remove a cordstrand from said shedding-hook; and means adapted to repeatedly shift a cord-strand into a shedding-position engagement with said shedding-hook. w
