BRAIDING MACHINE.

Application filed October 20, 1923. Serial No. 669,648.

To all whom it may concern:

Be it known that I, MAX Knrssrnr, a citizen of the German Republic, residing at Wyomissing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Braiding Machines, of which the following is a specification.

My invention relates to braiding machines; and my main object is to provide for so controlling the movement of the bobbins in the production of flat braids as to enable the flat laying of awide strand, or. of a plurality of narrow strands, at the edges of the fabric, by avoidance of the well-known twisting or buckling action thereon which is incidental to the turning of the carriers upon a terminal race-circle. A further object is to provide an improved bobbin carrier whereby extended support for the carriers is provided, and which is particularly adapted for use in securing such non-twisting movement of the carriers though otherwise advantageous. The' invention is fully described in connection with the accompanyf ing drawing illustrating a preferred embodiment thereof, and is clearly defined in the subjoined claims.

Fig. 1 is a diagrammatic plan-view indieating a carrier race-way comprising the minimum of tworace-circles; each of these being a terminal circle and showing an alternative loop-extension through which certain carrier shuttles may be traversed while others pass directly around the circle.

Fig. 2 is an enlarged cross-sectional view, on the line 22 of Fig. 1, but showing in detail 8. preferred form of my improved bobbin carrier and its relation to the race-way late of the machine, the usual .horned rive ears therefor being indicated by dotted ines.

Fig. 3 diagrammatically indicates in a sin 1e showing the edge-wise distortion of bot a single flat strand, and a, group of three strands, as ordinarily braided; while Fig. 4 indicates the improved elfect sought for and attained by means of my invention.

Fig. 5is a eating a modi shown, provides for changing the order of dia ammatic plan view indiarrangement; which, as

three disconnected carrier shuttles as they travel around each terminal circle.

The intersecting race-circles 6, 6, are formed as usual in the top plate 7 of the machine; the central' quoit 8 which, forms the inner wall of each circle, being mounted upon a central post on which the meshing toothed wheels and horned carrier drive discs are mounted as in ordinary braiding machine construction; the posts 9 and carrier drive discs 10 only being indicated.

These drive discs 10 commonly engage depending pins or projections 16 of the carriers to traverse shuttle portions 16 of the latter in the race-way circles 6, 6; said discs belng formed with any desired number of so-called horns or projection-engaging recesses, the arrangement of which is indicated the plan views by dotted radial lines 10,

The improved bobbin-carrier indicated in Fig. 2 comprises a base plate 20 on which the bobbin or bobbins 21 three as shown, are mounted; said base plate being provided with two ivotally secured shuttle portions, each of w ich p'ortions comprises a shuttle 16 adapted'to travel in the race-way, a pivot 16 an aged in an end pivot aperture of the base p ate, and a depending drive projection 16" for engagement b The spacings of these s uttle portions on the base plate 20, corresponds with the spacing of the horns 10 on the drive discs 10 so that two adjacent horns of the latter will constantly en age the same to jointly support the base p ate and bobbins thereon; one of the pivot apertures 20 in said base plate being elongated as indicated so as to permit of required free movement in the race-way.

the drive discs 10.

To overcome the twisting action upon the 1. er of the travellingshuttles is accomplished by providing said terminal circle 6 with a loop extension 6 having its spread inner ends 6 arranged to communicate with the race-circle as controlled by means of a suitable switch 25, this control being determined as desired by an ordinary jacquard or pattern mechanism operating in well known manner upon the spring pressed switch bar 25 or by means of a gear driven cam such as that shown in Thun Patent No. 898,939 of Sept, 15, 1908. A carrier shuttle 16 which is admitted to the loop extension 6 of therace circle, may

have its drive projection 16 engaged by special horn gears indicated by the dotted circles 10", 10, 10 and driven with the series of toothed gears on the posts 9, so as to properly traverse said carrier through the loop extension 6.

In Fig. 1 three bobbin supporting carrier base plates 20 are shown; one in midway position and the others aspassing around the respective terminals so as to reverse the order of their respective shuttles 16. Following the midway carrier plate 20 in the direction indicated by the arrow, it will be seen that its advance shuttle, marked 1, is represented by the dotted line showing of said plate as having been entered into the loop extension 6 of the race way by the opening of the switch thereto; the switch however being shown as subsequently moved so as to open the direct race-circle-path for the succeeding shuttle, marked 2; so that the latter will be put into advanced position as it is traversed on this shorter course, while the shuttle l is made to traverse the loop extension 6* and. to take second position in the reverse travel of the plate 20 through the race circles 6, 6. This reversing of the relative positions of the carrier shuttles 1 and2 neutralizes the twisting effect incident to passing them around the terminal as usual, without such change in their order, and insure the fiat laying of the bobbin strands as indicated in Fig. 4.

It will be seen that my improved carrier base plate 20, with its spread shuttles 16, 16 supwrted at all times upon different portions of the top plate 7 of the machine, itself provides a peculiarly steady support for the bobbin or bobbins 21 carried thereby, with obvious advantage in all cases; and that it is especially advantageous in effecting the reversal in the order of movement of the shuttles as above described or eliminating twisting action upon the strands. This latter action however may be eifected without employing such improved base plate as is indicated in diagrammatic view Fig. 5; the latter also showing a modification of my main invention in which the order of progression of three successive shuttles, each forming part of a separate carrier, is provided for. In this case, as will be seen, two

neeeeeo loop extensions, 6 and 6 respectively, are added to each terminal race circle with separate switches to control their communication with the race circle- 6; the length of the longer loop extension 6 being adapted to lengthen the course traversed by the first carrier shuttle 1, sufiiciently to permit the second carrier shuttle 2 to get ahead of it owing to the shorter course provided for it.
