' Application led June 20, 1914. Serial No. 846,264.

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 improvements in 1o braiding machines employing a set of spaced carriers adapted to carry a set of threadsupplying devices, a common carrier adapted to carry a, second set of thread-supplying devices, means for supporting and' rotating said set of carriers' and said common carrier in opposite directions to each other and for causing threads delivered from the said de,- vices carried by the common carrier to move sinuously through the spaces between and around the spaced carriers and the threadmachine shown and described in my Letters Patent No. 1,144,716, dated June 29, 1915, to

which reference may be had.

rlfhe object of my present invention is the simplification of the mechanism employed 3u for guiding the threads delivered from the .thread-supplying devices of the common' carrier sinuously through the spaces between and around the spaced carriers and the thread-supplying devices, carried thereby, as will be hereinafter fully ldescribed and particularly claimed.

In the accompanying drawings, illustrating my invention: Figure 1, is a side elevation of my improved .braiding machine,

parts of the thread guiding arms for 'the upper thread-supplying devices being 'broken away. Fig. 2, is a view of one o f the upper thread-supplying devices and its carrier detached from the machine. Fig. 3,y isa development of a portion of the braid produced by my improved' machine.' Fig. 4, is a view, partly in section, of one of the thread Aguiding devices for'the lower threadsupplying devices. Fig. 5, is a front elevation of the machine, partly in section, on line 4 4 of Figli. Fig. 6, is a horizontal section,.on line 6 6 of Fig. 5. Fig. 7is a horizontal section, on line 7-7 of Fig. 5. Fig. 8, is a vertical section of the lower portion of the machine, on line 8-8 of Fig. 6. Fig. 9', is a plan ofthe outer and inner members between which the endless sinuous course is formed and which support the sectional track.

Referring to the drawings, 2 designates the base of the machine frame, 3 a central standard rising fixedly from the 'base and 2O three outer standards rising ixedly from the base and spaced around the central standard 3. Secured on the central standard 3 is a horizontal plate 18, and secured on the outer standards 20 is a horizontal plate 21, in the same` horizontal plane with and surrounding the plate 18, but spaced therefrom and providing an endless, sinuous course between the two plates 18 and 21, as clearly shown in Fig. 9.

Rotatable on the central standard 3 below the plate 18is a carrier 8, carrying a set of thread-supplying devices 9 which `are mounted on suitable brackets 10 secured to the carrier 8. The carrier 8 is rotated by the main shaft 11 through co-acting bevel gear wheels 12 and 13 securedto the/carrier 8 and shaft 1l, respectively. The main shaft 1l is mounted to turn in bearings 14 and 15 on the base 2; and the main shaft l1 is provided with a pulley 16 by means of which` it may be driven.

Secured on the outer portion of thecarrier 8 is a sectional, internal gear ring 29 which surrounds and coacts with the outer portions of small gear-wheels 28l secured on the lower ends of a circular set of regularly spaced vertical shafts `27 extending up through the plates 18 and 21 and rotatable therein. The upper ends of the shafts 27 have small gear wheels 26 secured thereto and the inner portions of the gear wheels 26 co-act with teeth formed on the outer portions of a circular set of regularly-spaced carriers 23, carrying a set of thread-supplying devices 24, corresponding in number with the devices of the set 9. The set of carriers 23 slide in and are supported and guided by a sectional annular track 22 which is formed bythe plates 18 and 21 and parts secured thereto and which is intersected by the sinuous course 35, as clearly shown in Fig. 9. f

The threads from the lower thread-supplying devices 9 pass first through guide eyes 19 on the bottom of the carrier 8 and then up through vertical tubes 32 and from the tops of the tubes 32 to the braiding region A. Each tube 32'is carried by the from the center of the machine, as the tube n moves through a slot 33 in the carrier 8 through which the tube 32 extends, andalso through the space between adjacent sections of the gearring 29. The tubes 32 also-eX- tend up through the sinuous course 35 to a position near the same level with the tops of the upper thread supplying devices 24; Each tube 32 is surrounded by an anti-friction roller 34 (see Fig. 4)' adapted to cooperate with the walls -of the sinuous course 35.

The thread from each upper thread-supplying device 24 passes around vertical pins 37 on its carrier 23, thence to and through guide openings ina vertical pin 38 on its carrier 23 and from the upper end of the pin 38 to the braiding region A.

The braided material B passes/from the braiding' region A up through a guide tube 36 secured to an angle arm 39 which is vertically adjustable in a bracket 40 carried b a pair of horizontal shafts 41 and 42 whic extend between and are supported by side standards 43 and 44 Xed on the base 2, the

bracket 40 being ixedto the shaft 41, the

shaft 41 being vfixed to the standards, and the shaft 42 being rotatable in the standards.

. The braided material B passes up from the tube 36 to and around a grooved take-up wheel 45 mounted to turn loosely on the fixed lshaft 41 between two `fixed collars thereon. The'take-up wheel 45 has a gear wheel 46 formed thereon which co-acts with a pinion 47 secured on the rotatable shaft 42.

Secured on the outer end -of the shaft 42 isl a gear wheel 48 co-acting with a gear wheel 49 on one end of a short shaft 50 mounted to rotate in a bearing 51 on the standard 44. The other end of the shaft 50 has a worm wheel 52 secured thereon which is driven by a'worm 53 secured on the upper end of a vertical shaft 54 whichismounted to turn in a bearing 55y on the standard 44. The lower end of the l'shaft 54 carries a beitel gear wheel 56 which co-acts with a similar wheel 57 on the main driving shaft 11.

The operationof the machine is as follows: Power is applied to the main shaft 11 to rotate yit in the direction of the arrows in Figs. 1, 5 and 6 thereby rotating the carrier 8 in the direction of the arrows in Figs.

1 and 7 and rotating the take-up wheel 45, at a much slower speed, inthe direction of the arrows in Figs. 1 and 5, by the gearmg between the take-up wheel 45 and the main shaft 11. As the carrier 8 is thus rotated 5 in ythe direction of the-arrows in Figs. 5 and 6, the gearing between the carrier 8 and the set of carriers 23 rotates the set of carriers follow the sinuous course 35 by the rollers 34 engaging the walls thereof. This 'operation causes the tubes 32 to intersect the path of the upper thread-supplying devices 24 and to move toward and from the center ofthe machine from the outside to the inside and from the inside to the outside of said path. This operation also causes the tubes 32 to mover.

between the adjacent sections of the gear ring 29 so that thetubes 32 may pass around the outside of the shafts 27 supported by the plate 18 and around the inside of the shafts 27 supported by the plate 21, this being an important feature of my invention.

The gear wheels 26 are.so related to the teeth on the carriers 23 that before the teeth of a carrier 2,3 leave a gear wheel 26 they are engaged by the next adjacent gear wheel 26, so thatthe carriers are always maintained equally spaced from each other while being driven.

The tubes 32 move around the machine with the,` devices 9 in the opposite direction to the devices 24, andthe timing of the movement of'each tube 32 with respect to the movement. of the devices 24and their carriers 23 is such' that each tube32 will pass between the devices 24 and between their carriers 23, and around the outside and then around theinside of two adjacent devices 24 and their carriers 23 in alternate succession, and between each succeeding two adjacent devices 24 which were passed around by each tubes precedingv tube, thus causing the i tubes 32 to interweave the threads from the devices 9 between and around the devices 24 yand the threads delivered therefrom for the production of the braid illustrated in Fig.

3. in which each thread passes over and under two threads-in alternate succession'and between the two threads overand under which the next adjacent thread passes. As rapidly as the braid B is formed, it is drawn up through the guiding tube 36 by the`take` upwheel 45 which also draws the threads from the thread-supplying devices 9 and 24,

during, the weaving of the braid.

I claim:

In a braiding machine, the combination of a supporting frame, two horizontal plates supported on said frame and disposed in the and said rotatable carrier in opposite direc'- tions to each other, and a set of verticallyarranged thread-guiding tubes for said second set of devices, said tubes being movable on and carried by said rotatable carrier and extending through and guided by said sinuous coursewhen the carrier isl rotated.
