Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed May 15, 1907. Serial No. 373,23.

To all whom it may concern:

Be it known that I, JACOB LUNDGREN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Braiding M achincs, of which the following is a specification.

This invention relates to that class of braid- '10 ing mai'whincs wherein two sets of bobbins are employed, and each thread from one set of bobbins is passed entirely around two bobbins of the other set during the braiding operation, as illustrated in my application for patent Serial Number 179,807, filed Novemher 4th, 1903, to which reference may be had.

I The object of my present invention is to I produce a more simple and eilicient machine of this class. i

'llaving this'objcct in view, the invention consists in the novel construction and combi nations of arts hereinafter fully described and particularly pointed out in the claims.

In the drawin: -l igure 1 is an elevation of a braiding machine embodying my invention. Fig. 2 is a sectional plan view thereof, enlarged, as seen from the line 2-2, of Fig. 1. Fig. 3 is a sectional plan View, as on the line 3-3, of Fig. 1, certain parts being omitted. Fig. 4 is a vertical section as on the line ti""4, of Fig. 2. Fig. 5 is a sectional detail showing one of the upper bobbin carriers, and adjuncts, and the position of one of the upper bobbins with. respect to the thread carrying arm l or one of the lower bobbins, when said. arm passes said bobbin.

The main frame of the machine comprises the bed plate 6, and the standards 7 and 8. Rising from the bed plate is a centrally arranged tubular post 9, to which is fitted the hub 10 of a frame 11, so as to be rotatable thereon.

Journaled in bearings 12 and 13 on the bed plate 6 is a driving shaft 14 which is provided on its outer end with a suitable driving pulley 15, and on its inner end with a beveled gear wheel 16', in mesh with a similar wheel 17 on. the hub 10 by means of which the frame 11 is rotated. Arranged around the 59 frame 11 and secured thereto, are upwardly projecting shafts 18. The upper ends of the shafts 18 support horizontally arranged plates 19 which extend toi'ard each other,

and terminate before meeting each other,

55 therebyleaviug open spaces bctween'thcir opposite ends, Arranged directly below the vertical spaces between plates 19 and? Extending through the spaces laetweentimplates 19 and 20, and fitted to the trac'ku ways 22, are sector-like carriers 23, adapted to travel around said tracl ways, the length of the carriers 23 being much greater than the distance between the adjacent ends of the plates .19 and the adjacent ends of the plates 20. The peripheries of the carriers 23 are provided with gear teeth, adapted to be engaged by the teeth of pinions 24, which are rotatably mounted on the shafts 21, and arranged between the plates 19 and 20. These pinions 24 are so placed and arranged with relation to each other and to the trackways 22, that during the rotation of said pinions, the carriers 23 willbe rotated about the tracirways 22, and that before the teeth of the carriers escape one pinion, said teeth will be engaged with another pinion. The pinions 24 are driven by gear wheels 25 on the upper ends oi sleeves 26 which are rotatably mounted on. the shafts 18. The lower ends of the sleeves 26 are provided with gear wheels 27 in mesh with a fixed gear ring 28, which is supported on suitable posts 29 rising irom the bed plate 6. Thus it will be seen that, through the gear just described, during the rotation of the frame 11, the carriers 23 will. be bodily rotated around the machine, and at the same time, independn ently'rotated about their respective trackways. Extending upwardly from the car riers 23 through the spaces between the adjacent ends of the plates 19, are frames 30 carrying the upper set of bobbins, 31. These frames 30 cariyposts 32, the upper ends of which are provided with thread delivery eyes 33 which receive the threads 34 from the bobbins 3] and deliver them to the braiding point,

Mounted on brackets projecting-from the sleeves 26, are lower bobbins 35; and fixed to the sleeves 26 are the angular thread guiding arms 36 for the threads 37 from the lower bobbins along which the threads 37 from the bobbins 31 are guided through suitable eyes,

plates 19 and 20, are circular grooves or as shown; The arm 56 provided with a vertical portion which. clears the ends of the supergiiosed plates 1?) and 20, and passes through the spaces between the ends of said plates and the next adjacent plates when the arm is rotated with its sleeve. Each arm 36 is also provided with a vertical portion 39 which clears the two next adjacent bobbins 31 during the rotation. of said arm. The free end of each arm 36 is provided with a threaddelivery eye, 40, from which the threads 37 are delivered to the braiding point. During the operation. of each arm 36 about its own axis the vertical portion 39 thereof describes circle around the two adjacent bobbins 31, under which the arm passes. It follows, therefore, that the paths traversed by the vertical portions 39 and the threads 37 carried thereby intersect each other and that two adjacent bobbins 31 are not only inclosed by the path traversed by one thread 37 but are also separately inclosed by the paths traversed by the threads 37 on the respective thereof. The timing of the movement of the carriers 23 around their track-ways with respect to the movement of the arms 36, is such that when. a particular arm 36 is passing a particular bobbin 31, the carrier of the bobbin will over that portion of its trackwav w. ch is vnthmthe path traversed by the vertical portion 38 of the arm, and that the same carrier, upon meeting the vertical portion. 38 of the next adjacent arm, will pass over that portion of its track-way which is withinthe path traversed by the vertical portion 38 of its next adjacent arm. Thus it will beseen that each bobbin 31 is alternately sup'oorted within the two paths traversed by t; e two adjacent rotatin arms 36,

in order to permit the passage of the threads 37 from the lower bobbins entirely around the bobbins 31 and threads 34, delivered therefrom which is one of the peculiar re quirements of a machine of this character.

The thrcads34 and 37 pass from the eyes 33 and 40 to the braiding point, which islocated at the lower end of a centrally arranged tube 41 through. which the product of the machine passes, and which is supported by an arm. 42 projected from a fixed shaft 43 which extends between the upper ends of the standards 7 and 8. I

The product of the machine passes up through the tube 41 and around a suitable take up wheel 44 which mounted loosely on the shaft 43. The take up wheel 44 is actuatedby a gear wheel 45, fixed to the side thereof, and in mesh with a pinion 46 on a shaft 47, having its hearings in the standards 7 and 8. ()no end of the shaft 47 extends outwardly and is provided with a gear wheel 4&8 in mesh with agear wheel 49 on one end of a SllQSf't shaft 56, mounted in a suitable bar iii. The other end of the shaft 50 is provided with a worm wheel 52 which is actuated by a I worm on the upper end of a vertical shaft 54.

The lower end of the shaft 54 has fixed thereto a beveled gear wheel 55, which is driven by a similar wheel 56 on the main driving shaft 14, to the end that when the main shaft 14 is actuated the take up wheel 44 will be rotated.

By the above described construction, it will be seen that when power is applied to the driving pulley 15, the rotation of the wheel 44 will draw the threads through the eyes 33 and 40, from the bobbins 31 and 35 respec tively, and up through the tube 41. During thisoperation, the threads 34 from the bohbins 31 are being delivered direct to the braiding point, and each thread 37 from the bobbins 35 is being guided by its arm 36 entirely around two adjacent bobbins 31; the two bobbins 31 that are inclosed by the path of one thread 37 being separately inclosed by the paths of the threads from the adjacent bobbins 35. Thus the threads from the two sets of bobbins 31 and 35 are braided together upon meeting the braiding oint, to produce a cord, and said cord wil be provided with a twist due to the bodily rotation of the bobbins 31 and 35 around the machine during the braiding operation.
