25 Claims.

This invention relates to a method of and apparatus for assembling strands and more particularly to a semi-automatic apparatus by means of which the method may be practised for producing multi-conductor cords and the like.

In the electrical art, especially in telephone systems, it is desirable to employ multi-conductor cords for electrically connecting cooperating devices of the system. The Patent 1,954,979 of April 17, 1934, to William T. Barrans and Ben K. Ford illustrates an apparatus for automatically assembling one form of the multi-conductor cords.

An object of the invention is to provide a simple, eflicient and practical method of and apparatus for producing various types of strand assemblies.

With this and other objects in view the invention comprises an apparatus by means of which 20 a method may be practised for braiding a cover on strands to form cords wherein a timing mechanism automatically stops the braiding unit at selective intervals during which the operator may move the tubular guides for the strands beyond a the braiding point to produce slack in each strand so that portions of predetermined length of the strand may be secured to a gage member and the selective number of strands to be covered may be increased or decreased at will. Also, means is provided to cause the braiding unit to apply a closer braid at the beginning of each cord.

Other objects and advantages will be apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which Fig. 1 is a side elevational view of the apparatus, portions thereof being shown in section;

Fig. 2 is a front elevational view of the apparatus, portions thereof being broken away to illustrate the invention;

Fig. 3 is a fragmentary view of a portion of the strand controlling means shown in its raised posi tion;

Fig. 4 is a top plan view of the gage plate and associated parts;

Fig. 5 is a fragmentary view of one of the strand controlling elements, a portion thereof being shown in section;

Fig. 6 is a top plan view of the brake mechanism;

Fig. 7 is an enlarged fragmentary side elevational view taken along the line 1-1 of Fig. 2;

Fig, 8 is a fragmentary side elevational view of the structure shown in Fig. 7, and

Figs. 9, 10 and 11 are views illustrating some of the various types of cords which may be produced from the apparatus.

Referring now to the drawings, wherein like reference numerals designate similar parts throughout the views, numeral 8 designates a supporting table upon which is mounted a braiding unit 9. Although the braiding unit is a part of this invention it is not believed necessary to show it in detail in order to illustrate the invention. The braiding unit may be of any well known type comprising the usual rotatable carriers for respectively carrying the inner and outer sets l0 and ll of bobbins or cops to form a covering on strands i2 at the point l3, which hereinafter may be described as the braiding point. A stationary tube i5 extends upwardly through the braiding unit for rotatably supporting the latter and has a head portion l8 removably secured to the upper end of the sleeve and has apertures in spaced circular formation to guide strand controlling elements The elements II are relatively long, extending from points l8 shown near the bottom of Figs. 1 and 3 to positions near the braiding point i3 and are axially bored to allow the strands l2 to pass upwardly therein to and through apertures near their upper ends, the strands being held against downward movement by resilient members l9 (Fig. 5). The elements i! are rigidly held in radially spaced positions by a retaining member normally held in engagement with the upper edge 21 of a tubular guide 22 by means of a helical compression spring 23, the upper end of which engages the lower or inner portion of the head IS. The tubular guide 22 has an integral annular flange fixed to and rigidly held by a bracket 25 mounted upon the table 8. Slidably disposed in the guide 22 is a tubular actuating or lifting member 28 normally positioned with its upper edge 21 spaced a desired distance beneath the upper edge 2| of the guide, the purpose of which is to allow suiilcient movement of the actuating member before it is moved into engagement with the retaining member 20 to allow a sufiieient slack in each strand before moving the elements l1 upwardly.

Any desired number of strand controllinng elements may be employed, in the present instance there being six shown (Fig. 4), and for each element there is provided a reel of strand material, these reels, indicated at 28, being positioned in groups of three rotatably supported by shafts 30 removably supported by the table 8 (Figs. 1 and 2). A pair of sleeves 32, positioned in parallel relation and rotatably mounted upon rods having their ends fixed to brackets mounted upon the table, serves as guides for the strands being drawn from the reels (Figs. 1 and 3). The strands pass downwardly from the sleeves 32 to the lower end of the actuating member 28. To the lower end of the member 28 is removably secured an annular guide member 33 having rounded lower edges to guide the strand material as it is drawn upwardly to and through the strand controlling elements. I1.

A mechanism is provided to move the actuating member 28 upwardly when the braiding unit is stopped. This means comprises a treadle 38 having an adjustable stop 38 to limit its downward movement, the treadle being fixed to a shaft 48 journalled in brackets 4| secured to the table 8. Movement of the treadle downwardly to the dotted line position (Fig. 1) causes a rocking of the shaft 48 clockwise and a similar movement of a spring arm 43 and a lifting arm 44, which are also fixed to the shaft 48. The spring arm 43 has its upper end connected to one end of a helical tension spring 45, the other end'of the spring being secured to a fixed bracket 48 mounted on the table. The purpose of the spring 45 is to rock the shaft 40 counter-clockwise to return the actuating mechanism to its normal position when the foot treadle 38 is released. Pivoted to the outer end of the lifting arm 44 is a link 88 connecting the arm operatively to a lever 5| between the ends of the latter. One end of the lever 5| is fixed to a hollow shaft 53 rotably mounted upon a solid shaft 54 which extends from one side of the table to the other where its ends are rigidly secured thereto, as illustrated in Fig. 2. A similar lever 58 is also secured to the hollow shaft 53 at one end thereof and, in its normal position, extends inwardly and downwardly in a direction parallel to the lever 8| (Figs. 1 and 2). Pivoted to the inner ends of the levers 5| and 88 are links 51 which extend downwardly therefrom and have their lower ends pivotally secured to guide member 33. In this manner the actuating member 28 is operatively connected to the treadle 38 to be moved upwardly when the treadle 38 is moved downwardly. The purpose of this movement of the actuating member 28 is to move the controlling elements" above the braiding point I3 so that the operator may, when the braiding unit is idle, form loops in certain of the strands I2 being covered so that uncovered portions will be present at the end of each cord section.

Whenthe controlling elements I! are moved upwardly through the actuation of the treadle 38 their upper ends pass through apertures 88 in a gage unit 8| (Figs. 3 and 4) so'as to position the strands projecting from the elements thereabove. By viewing Fig. 4 it will be observed that the unit 8| has a relatively large aperture 82 concentric with the advancing cord and provided with a plurality of radially extending spring compressed plungers 83 having concave inner ends conforming to the cord as it leaves the braiding point to serve as guides for the cord. Slots 84 extending from the apertures 88 to the aperture 82 provide passageways for the strands I2 as they are moved upwardly during upward movement of the elements I1. A plurality of slots 85 extending radially for desired distances from points near the aperture 82 adjustably receive retaining elements 88, which in the present instance are in the form of resilient hook members, around which the strands I2 may be looped or bent. The retaining elements 88 may be formed with collars larger in diameter than the cross sectional dimensions of the slots 85 and may be adjustably ing integral portions by the aid of which the unit may be secured to a cross bar or member 88, the ends of the latter being supported by upright bars 88, the lower ends of which are rigidly mounted in brackets upon the table 8.

The cross bar 88 has also fixed thereto a bracket 12 for supporting a shaft I3 for a plu- 1 rality of idler pulleys I4. The finished cords or strand assemblies which are held together by the braiding material are directed upwardly about one of the pulleys 14 around which it passes to a groove of a capstan I5, the latter being rotatably mounted upon a shaft 18, suitably supported by the cross bar 88 and driven from a constant speed means (not shown). The inner end of the shaft 18 has fixed thereto an arm 11 carrying in its outer end a pin '18 normally urged inwardly by a spring (not shown) and positioned to be forced into any one of a plurality of apertures I8 circularly disposed about the shaft 18 in the adjacent end of the capstan. The pin I8 may be moved outwardly by the aid of a head member 88 which may be gripped by the operator.

Means is provided to automatically stop the actuation of the braiding unit at predetermined intervals or after a cord of a predetermined length has been formed. This means, in addition to mechanism for automatically disconnecting the braiding unit from its driving means, includes a braking means to quickly stop the unit. The braking means (Figs. 1, 2, 6, '7 and 8) comprises an endless chain 85 passing around sprocket wheels 88 and 81, one or both of which may be driven by constant speed driving means (not shown), for example that employed to drive the braiding unit 8, to advance the upper portion of the chain in the direction of the arrow at a predetermined speed during actuation of the braiding unit. Mounted upon the chain 85 is a cam block 88, the upper surface of which is tapered to ride beneath a brake actuating member 88 adjustably mounted upon a horizontal element 88. The member 88 is adjustably secured to the element 88 by means of a bolt or other suitable means extending through one of a plurality of elongated slots 8| in the element. This brake actuating member also has a tapered surface 82 positioned to be engaged by the tapered surface of the cam block 88 when riding therebeneath to' cause movement of the member 88. and the element 88 upwardly through an are controlled by a link 83 and a lever 84 which are pivotally s'ecured to and support the element.

Brackets 88 rigidly mounted upon the table 8 pivotally support the link 83 and the lever 84. The lever 84, although shown in two parts fixed tothe ends of a shaft journalled in its bracket, may be considered as a single lever to simplify the description. The upper end of the lever 84 is operatively connected to a lever 88 through an adjustable link I88, the lever 88 being pivoted at IN to a stationary bracket or support I82 mounted upon the stationary portion I83 of the braiding unit 8. The stationary portion.|83, as illustrated in Figs. 1 and 2, is circular in general contour, having an outwardly projecting annular flange I04 upon which is movably disposed a brake ring I05 having secured thereto, at spaced positions, brake shoes I06. The general formation of the brake shoes I06 is illustrated in Figs. 6, '7 and 8, each brake shoe having a tapered surface I08 positioned away from a similarly tapered surface I09 of one ofthe rotatable carriers of the braiding unit so that when the brake shoes are raised these surfaces will be brought into intimate engagement to cause the brake shoes to stop rotation of the braiding unit. The brake ring I05, carrying the brake shoes I06, is moved through the actuation of the lever 99, the operative connection between the ring and the lever consisting of a pin I I2 carried by the ring and receivable in the upper slotted end of the lever as i1- lustrated in Fig. 1. It will be observed that through the action of the cam block 88, on the chain 85, in engagement with the actuating member 89 to move the element 90 in a clockwise arcuate path, controlled by the link 93 and the lever 94, clockwise movement is imparted to the lever 94 to rock the lever 99 counter-clockwise through the link I00, causing clockwise movement (Fig. 6) of the ring I05 and brake shoes I06. Cams II4 having tapered surfaces II5 are disposed in cut-away portions of the annular flange I04, where they are rigidly secured in place adjacent the brake shoes. Diametrically opposite the lever 99 and mounted upon the brake ring I05 is a latch cam I20 having a tapered surface I2I positioned to engage a latch I22. The latch I22 is pivotally mounted at I23 upon an arm I24 and is held in engagement with the tapered surface I2I by means of a flat spring I25. One end of the arm I24 carries a pin I26 which is movably disposed in an elongated aperture in the latch cam I20, while the other end of the arm is secured to one end of a tension spring I21, the other end thereof being fixed at I28 to a stationary support (not shown). A stationary lug I29 fixed to a suitable means (not shown) is positioned to be engaged by the latch I22 to hold the ring with the brake shoes in inoperative position. The mechanism actuated through the movement of the brake actuating member 89 caused by its engagement with the cam block 88 moves the brake ring I05 clockwise (Fig. 6) a sufficient distance to cause the latch cam I20 to move the latch I22 free of the stationary lug I29. When this takes place the spring I21 is rendered effective to cause a continued clockwise movement of the brake ring to move the brake shoes carried thereby so that their tapered 5 surfaces I I6 will ride on the tapered surfaces I I5 of the cams I I4 (Fig. '7) to move the tapered surfaces I08 of each brake shoe into intimate engagement with the tapered surface I09 of the rotatable carrier, thus stopping the braiding unit. The brake mechanism is held in this position until the operator is desirous of again causing actuation of the braiding unit 9 and chain 85, at which time the block 88 moves free of the member 09, allowing the entire brake mechanism r to return to normal position against the force of spring I2'I to move the latch I22 again into engagement with the stationary lug I29. The element 90 is of sufficient weight to cause the brake mechanism to return to normal position, yet if desired it may be assisted by a spring or other suitable means.

This brake means illustrates one means for stopping the actuation of the braiding unit. It should be understood that other means may be associated with the brake operating means to assist in stopping the braiding unit. For example, a switch (not shown) for opening and closing an electrical circuit through an electric motor, which might be employed to drive the braiding unit, the sprocket wheels 86 and 81 for the chain 85 and the capstan shaft I6, may be positioned to be closed by the element as it reaches its uppermost position in the actuation of the brake means to open a circuit to the suggested motor, the switch being operable when the element 90 advances to its lowermost position to close the circuit. The possibility of employing such switch controlling means is apparent and not believed necessary to show in detail in order to illustrate the invention.

With this apparatus a continuous covering material is formed through selective stages of operation of the braiding unit, the latter being stopped at predetermined intervals through the braking means including the mechanism for actuating the brake shoes I08 and other means (not shown) associated therewith to disconnect the braiding unit from its actuating means. The time interval of operation of the braiding unit coupled with the speed of advancement of the finished products through the rotation of the capstan I5 determine the length of the strand assemblies formed by the apparatus. The length of these strand assemblies may be varied by securing additional actuating members 89 to the element 90 and/or by securing additional earns 88 to the chain 85. Furthermore, strand assemblies of varying lengths might be formed by varying the relative positions of the actuating members 89 on the element 90 or the relative positions of cam members 88 on the chain 85.

To illustrate the operation of the apparatus, let it be assumed that strand assemblies formed of two strands I2 .are to be formed. While the braiding unit 9 is at rest the operator, by moving the treadle 38 downwardly against the tension of spring 45, causes the levers 5I and 56 to move counter-clockwise about the shaft 54 to lift the links 51 and therewith the actuating member 26. As shown in Figs. 1 and 2, the upper edge 21 of the actuating member 26 is positioned below the upper edge 2I of the tubular guide 22 upon which the retaining member 20 for the strand controlling elements I'I normally rests. Therefore, the vertical movement of the actuating member 26 from its lowermost position, shown in Figs. 1 and 2, to the position where its upper edge engages the retaining member 20 brings about the forming of slack loops in all the strands adjacent the reels 28. This slack in the strands is maintained, as illustrated in Fig. 3, as continued vertical movement of the actuating member, through the downward movement of the treadle 38, moves the retaining member 20 with the strand controlling elements I! upwardly against the force of the spring 23 to move the upper ends of the elements beyond the braiding point I3 and above the gage member 6I, Figs. 3 and 4. With the elements I] in the and eventually secured to a take-up reel (not shown). After the elements I! and their actuatingmeans have returned to their normal positions the braiding unit may then be set in motion, forming a covering on the selected strands, the braiding unit continuing the forming of the covering on the strands until the desired length has been reached, at which time the cam block 88 will ride beneath the member 89, causing actuation of the mechanism linked with the brake ring I05 to cause actuation of the brake shoes I06 to stop rotation of the braiding unit. At this point the operator may again actuate the treadle 38 to move the strand controlling elements I! to their uppermost positions and i if it isdesired to form strand assemblies as illustrated in Fig. 10, this form having loops I20 and l2l in the strands free of the covering material, the operator may draw the strands through their respective elements I1, which is easily accomplished due to the slack loops formed near their reels, and hook the strands over selected retaining elements 66, as shown in Fig. 4. The strand controlling elements I! are again allowed to return to their normal positions. formed in the strands may represent the end of one strand assembly and the beginning of another. Although the covering is continuous this covering and the strands may be severed to form individual strand assemblies. To eliminate unravelling of the covering material when it is cut at the juncture of the strand assemblies, means has been provided to form a very close weave of the covering material at this point. This is accomplished by the operator withdrawing the pin 18 from the aperture 19, in which it is disposed, and allowing the pin to rest upon the surface .of the capstan 15 the desired position between two of the apertures so that when the braiding unit is set in motion the shaft 16, which is operated in synchronism with the braiding unit, will not cause advancement of the strands until the arm 11 has been moved clockwise through the rotation of the shaft 9. sufficient distance to align the pin 18 with the next aperture and .allow its spring (not shown) to cause operative connection between the shaft and the capstan. The close weave caused by this mechanism is illustrated at I22, Figs. 9, 10 and 11.

The operator may, if he chooses, continue to form the strand assemblies illustrated in Fig. 10 by carrying out the same steps as previously described. However, additional strands may be added to those already being presented to the braiding unit to form strand assemblies, as is illustrated in Figs. 9 and 11. This is brought about by moving the strand controlling elements to their uppermost positions, selecting the additional strand or strands, and fastening the free end or ends thereof to selected retaining elements 66, and after the controlling elements II have again been lowered and the braiding unit again set in operation, this additional or these additional strands will be included in the cover formed by the braiding unit. The retaining elements 66 are so constructed and embody sufficient resiliency to hold the strands until, during the advancement of the completed strand assemblies, they are pulled upwardly and freely released therefrom.

Although only three different types of strand assemblies are shown in the drawings, numerous other types of strand assemblies may be formed. Furthermore, only six strand controlling elements I! are shown, but it should be understood that The 100138 any desired number. of these elements maybe employed to present desired groups of strands to the cover forming means, namely the braiding unit. Furthermore, a plurality of strands may be passed through each element. It is, therefore, possible to present any desired number of strands to the cover, form measured loops at the juncture of the strand assemblies, which is accomplished through the gage member BI and its adjustable retaining element 86, and if so desired any selected number of strands which has been fed to the braiding unit may be withdrawn therefrom by severing such strands while the strand controlling elements are in their raised positions.

In the present embodiment of the invention a braiding unit is illustrated for weaving a' continuous cover to which strands may be fed, but it should be understood that the invention herein disclosed is illustrative only and may be widely modified and departed from in many ways without departing from the spirit and scope of the invention as pointed out in and limited only by the appended claims.
