ROTARY BRAIDIING-MACHINE.

Specification of .Letters Patent.

Patented Dee. 3,1912.

Application filed September 3, 1909, Serial No. 516,089. Renewed March 2B, 1912. Serial No. 686,972.

To att whom tz may concern.'

Be it known that l, Annen PETERSEN, a subject of the King of Denmark, residing at 'nthrop, in the county of Suiolk and btate of Massachusetts, have invented new and useful Improvements -in Rotary'Braiding-hlachines, of which the following is a specification.

This invention relates to an improved rolo tary braiding machine, and the object is to provide a braiding machine which shall be capable of operating at a high rate of speed and increasing the output over machines heretofore used. This result is attained by providing' a set of spoolcarrie'rs traveling in a regular pathof movement in one direction, by providing a body rotating'in the opposite direction andfcarrying another set of spools and by providing strand carrying .20 levers which throw the strands alternately over and under the spool carriers.

Another important result obtained is that no slack forms in the strands and, therefore, no take-up devices are required. I

:175 The invention consists in the novel feautres of .construction and 'in the combination and arrangement of parts set forth in the following specification and particularly pointedv out in the appended claims.

Referring to the drawings: Figure 1 is a plan of; a braiding machine embodying my lnventi'on. l Fig. 2 is a side elevation of the same. Fig. 3 is a detail sectional view taken on line 3-3 of Fig. 1. Fig. 4 is an enlarged detail plan section taken on line 4-4 of Fig. 2 and partly broken away to save space in the drawings. Fig. 5 is a side elevation of one of the strand carrying levers and the bracket on which it is pivotally supported. F ig. 6 is a detail elevation viewed from the center of the machine showing two spools of'the upper, series and one spool of the lowerlseries, the lower Spool being shown on its spool carrier and driving gears being also shown.

Like numerals refer to like parts through` out .the several views of the drawings.

Iln thedrawings, 10 is a main driving shaft journaled in bearings 11 and l2 on a 5,0 frame 13 having legs 14 to support the saine on the floor'. A spider l5 constituting a part of the frame of the ,maehineis provided with a hub 16 in-which is secured a hollow stationary spind1e'l7 surmountedby'a. bushing 18. A sleeve 19 journaled on the spindle 17 has secured thereto a bevel gear 20 meshing into a bevel pinion 21 fast to the shaft 10, said gear and sleeve being preferably supported upon a radial ball bearingl 22. Journaled on the sleeve 19 is a miter gear 23 meshing into a miter gear 24 fast to the shaft 10, the former gear being preferably supported upon a radial ball bearingl 25. Fast to the .miter gear 23 is a large evel gear 26 in to which a series of bevel pinions 27 mesh, said bevelpinions being mountedy on shafts 28. The plnions 27 are arranged in pairs and the shafts of each pair terminate in a bracket 28 fast to a rotary member 29, while the outer ends of said shafts terminate in a ring 3() which is secured to the member 29 by a series of webs or spokes 31 thus constituting the member.. 29 'and the ring 30 a single rotating body, the member 29 being fast to and driven by the sleeve 19.l

It will be understood'by observing the ratio of the gears 20 and `21 and gears '23 and 24, that the member 29axid ring 30 are rotated in the saine direction as the gear 26', but at a less speed, the consequence being that the bevel pinions 27 are rotated on their own axes and revolved about the gear 26.

A series of thread-mass carriers 32 all .separatev and distinct from each other are mounted to slide in ways 33 formed in the ring 3() and upon ways 34 formed onthe brackets 28', said thread-mass carriers having formed thereon or fast thereto segmental gears 35i which are adapted4 to mesh into the pinons 27 in succession cach segmental gear being arranged to mesh with each succeeding pinion before passing out of mesh with the preceding pinion. be seen that the thread-mass carriers 32l are revolved about the ecnlerof the machine in a direction opposite 'to the direction of rotation of. the ring 30 andmember 25) and are maintained in their proper spacing with relationto each other.

Each of the thread-'mass Carriers 32 supports a spindlc upon which thc spool 37 is mounted to rotate.

- upon a rod 40 fast to said spool cartier the several strands' leading from ther-'several lthread carriers 39 tothe braiding point at The thread wound on` the spool 37 `leads therefrom around a guard.

ln this way it will ring-30, the threads leading from Vtheir respective spools to thread guides 45, respectively, and thence through thread guides 46,

v respectively, secured to brackets 47 mounted upon the ring 30, the last mentioned thread guides being located at'the axes of strand carrying levers 48 pivotally supported upon said brackets. The threads pass'from the thread guides 46 through thread guides` V49,

' 50 and 5l mountedl upon the levers 48 and thestrands extend from the last-mentioned thread guides through vertical slotsi52 in the ring 30 and through the spaces-'Which separate lthe brackets 28 from each other, to the braiding point atthe bushing 18. The funcpose said levers have journaledthereon Cain tion of the strand carrying levers 48 is to throw their strands alternately over and under the thread-mass carriers 32 to cause 'tivo series of strands to interlace With each other at the braiding point and for this purrolls 53 located in a serpentine slot 54 in a stationary cam 55 mounted on uprights 56 forming a part of theframe 13.

It will be observed that the t-Wo series of spools move .in regular circular paths -con-` centric with thecenter of the machine and the-"only reciprocating pa'rts of the machine are the strand carrying levers 48, and it is possible to make these levers so light that the machine is capablev of operating at a much higher speed than has-heretofore been possible. Furthermore, it is possible by increasing the number of the Strand carriers as by having two strand carriersto each spool carrier to interlace the strands to introduce a greater number of strands than there` are spool carriers, if desired, thus causing the fabric to be built up With greater rapidity than has heretofore been possible.`

1 I will now proceed to describe the' feeding mechanism. The hub 16 of the spider 15 supports a i* bracket 57 on which is rotatably supported an idler drum58 which guides the braided fabric as it passes'downwardly inside of the hollow spindle I7. vThe fabric passes from the idler 58 lseveral times around a feed` drum 59- -fast to a shaft 60 journaled in a vbearing 61.f ast to the frame 13, said shaft having fasttlierto a bevel gear 62 meshing into a bevel pinion 63. 1 The bevel pinion 63 Y is 'fastito a shaft 64 journaled in bearings 65 and 66, said shaft havingalso fast thereto ,a'wo-rm'gear 67 which meshes with a worm 68 fastfto the main driving shaft 10.- -As the mainfidriving shaft Vis rotated, the gearing just described imparts the proper rotation to the feed drum 59, therebyfeeding. the fabric from the machine at the'proper speed.

Yhile I have described the ring 30 carrying one setof spools` as rotating in one directionand the spool carriers 32 carrying the other set of spools as revolving inthe opposite direction, it uill be evident that vtheir motion is necessarily only relative and I have chosen in the present instance to move them in opposite directions forcenvenience of-construction and for attaining two to increase the speed of operation of the machine Without increasing the actual speed of rotation of any one of itsparts.

Having thus described'my invention, what -cure is:

1.v A rotary braiding machine having, in combination, a series of thread-mass carriers having segmental gears thereon, a series of pinions adapted to mesh successively with said segmental gears, a gea-i' meshing with said pinions, a body on which said pinions are journaled and upon which said carriers are supported and guided,a series 'of threadmass supports mounted on said body, means to imparta rotary motion tosaid body and said gear in the same direction but at differentspeeds, a series of strand-carriers carried by said body, and means acting on said strand-carriers to cause'the same to carry the strands leading from said thread-mass supports alternately over and under said thread-mass carriers.
