FREDERICK KLEIN, OF COLLEGE POINT, NEW-YORK, SSIGNOR T0 NATIONAL INDI- CATOR COMPANY, OF LONG ISLAND CITY, NEW YORK, A CORPORATION OF NEW Bambina MACHINE..

Application led .Tune 29, 1922. Serial No. 571,621.

To all whom it may concern.'

Be it known that I, FREDERICK KLEIN, a citizen of the United States, and resident of College Point, in the borough and county of Queens, city and State of New York, have invented certain new and useful Improvements in Braiding Machines, of which the following is a specification.

This invention relates to that type of machine in which two oppositely rotating tables or turrets are provided, each turret or table carryimr a series of spools or bobbins, the threa s from all of said spools converging at a braiding point above the machine and means being provided whereby y the threads from one series of bobbins will be interlaced with the threads from the other series of bobbins. The purpose of machines of this type is to produce a tubular braided fabric with or without a core. Such machines are'largely for braiding coverings on electric wires but of course it will be understood that they are capable of a great variety of uses.

@ne of the main objects of this inventionk is to suspend the inner series of bobbins at their upper ends on a rotatable turret in such a manner that the bobbins and the turret will rotate together and the use of an annular shuttle trackv will be avoided. This construction reduces the friction incident to the relative movement of the shuttles or bobbin carriers on the track.

Another important object of the invention is to provide a series of rotatable disks for supporting the carriers of the inner series and to provide said rotatable disks with means to permit the threads from the outer series of bobbins to pass under the bobbins of the inner series. The bobbin supporting disks constitute the inner turret or supporting member and revolve around the vertical axis of the machine and carry with them the inner series of bobbins. Each supporting disk is rotated around its own axis for the purpose of allowing the threads from the outer series of bobbins to pass under the inner series of bobbins as the Said inner series revolves around the machine.

Another object of the invention is to' provide means for guiding the outer ends of the inner series of bobbins. The purpose of this guidingmeans is to prevent any tendency of the shuttles or carriers to bind on the rotatable supporting disks. This machine is designed' or operationat a very high speed, and the louter ends of the inner series of bobbins tend to lift due to centrifugal force, and the guiding means is designed to hold the bobbins in a substantially neutral position and thereby to prevent the shuttles or carriers binding on the rotatable supportin disks.

There are other important o jects and advantages of the invention which will appear hereinafter.

Referring to the various parts by numerals 1 designates the base of the machine in 'tending rigid tubular post 2.

which is rigidly mounted an upwardly ex- In the base 1 is suitably mounted a horizontal drive shaft 8 carrying a pulley 4f at its outer end adapted to be engaged a. suitable clutch 5 to connect said driving pulley to the drive shaft, in the usual or any suitable manner. A beveled driif'fing pinion G is mounted on the innerend of the drive shaft, said pinion 6 engaging two beveled gears 7 and 8 and by means of which the bobbin carrying turrets are rotated in opposite directions, as will be fully hereinafter described.

Rotatably n'iounted upon the post. 2 is an inner driving sleeve 9 to the lower end of which a beveled gear 8 is rigidly secured. Mounted on the sleeve 9 is an outer drive sleeve' 10 which carries near its lower end the beveled gear 7. It is manifest from this construction that the driving sleeves S) and 1 0 will be rotated in opposite directions, the drive pinion 6 being arranged between said beveled gears. The driving pinion and the beveled gears 7 and 8 are preferably located within the, base of the. machine for safety and for convenience of oiling.

Rigidly secured to the outer driving sleeve, at a suitable point above the base, is an outwardly and downwardly flaring circular turret plate 11. To the outer margin of this turret plate is secured a series of upwardly extending arched bobbin supports 12, the lower ends of the two arms of these supports being substantially co-incident with the lower margin of the circular turret plate 11. As shown in Fig. 1 there are eight. of these supports 12 spaced equal distances apart around the turret. rlo the lower ends of the outer members of these arched supporting plates are secured carriers 13 which support the outer bobbins or thread carriers 14. These outer bobbins are supported ou horizontal spindles 15 mounted in suitable bearings in the carriers 13. The carriers 13 are connected together around the machine by brace bars 16.

The inner driving sleeve 9 carries on its upper end a spider frame 17 formed with eight radial arms 1S which extend outwardly and downwardly, as shown clearly in Figs. 1, 2 and 3 of the drawings. The lower outer end of each of these spider arms is tubular and forms a bearing for a short radially arranged shaft 19, said shaft extending outwardly and downwardly. To the upper end of each of said shafts 19 is secured a beveled pinion 20. Rigidly secured'to the upper end of the outer driving sleeve, just under the spider 17, is a crown gear 21 which meshes with all of the pinions 20. Rigidly secured to the outer lower end of each shaft 19 is a carrier supporting disk 22, each of said supporting disks being formed around its margin with an outwardly turned annular flange 23. Each of said suppm-tiingr disks is formed at diametrieally opposite points with two thread receiving and carrying notches 2i.

The bobbins 25 ofthe inner series are each mounted in a carrier frame consisting of an upper carrier head 2G; two outwardly and downwardly diverging side bars 27 connect'- ed to said head, and a large outer shuttlel plate 28 rigidly connected to the lower ends of the side bars 27. 'lhe bobbin spindles 25b are mounted in suitable beariiqgxs` formed centrally of the carrier head and in the shuttle plate, as shown clearly in Figs. 5,

7 and 1() of the drawings. Each shuttle plate 28 is substantially elliptical in forni with its longer axis horizontal and its end pointed. The side bars 27 are connected to the shuttle plate 28 near the ends of said plate. The carrier heads 26 are also substantially elliptical in form with their longer axis substantially horizontal and the side bars 27 are connected to said heads near their ends. l

Each carrier head 26 is arranged between two adjoining supporting disks 22 and is adapted to be engaged with and supported by said disks. Each carrier head is formed on its upper surface with two curved channels or grooves 29 which are adapted to receive the flanges 23 of the engaged supporting disks. The carrier head is also cut out on its upper surface to receive the supporting disks so that the upper surfaces of the carrier and the supporting disks will be substantially Hush with each other. The, two supporting disks are at an angle to cach other and the carrier head is dished slightly to bring its engaged port-ions into parallel relation with the supporting disks, as clearly shown in Fig. 7. To lock each carrier head to its engaged supporting disks, a cover plate 30 is provided, said plate being secured to the carrier plate by means of screws 31. The cover platcis of the same outline as the carrier head but is slightly larger in order to form an etlicient thread guide and to serve in the manner of a shuttle. as will be more fully hereinafter described. On the outer margin of each cover plate is formed a thread holding lip 82 with which the thread from the inner bobbin engages. The shafts 19 of the supporting disks are so arranged that the supporting disks are in planes inclined inwardly and downwardly toward the axis of the driving sleeves. The carrier heads are supported by said disks in such a position that the axes of the bobbins of the inner series incline outwardly and downwardly from the carrier heads. The inner series of bobbins are preferably suspended from their upper end at an angle which they would assume under the influence of the centrifugal force due to the speed of the rotating turret.

Each shuttle plate 28 is provided on its .loll

outer or lowerl side with .a horizontally extending g-uide shoe 33 which extends substantially` throu hout the length of the shuttle plate an is adapted to engage and slide freely in a grooved guide track 34. rIhis guide track is sectional, with open place 35 at the ends of said sections; and each sec-z4 tion is rigidly secured to the upper inner side of the arched supports 412. These supports 12 are carried by the outer turret late 11 so that the guide track sections wi rotate with the outer turret. The ide shoes 33 hold the carrier heads 26 in t eir roper angular relation with their engage supporting disks and prevent any binding which otherwise might possibly result from the high speed o rotation of the inner turret. It 1s manifest that there might be a tendency for the outer ends of the 'sus ended bobbins to rise and thereby cause a inding of the carrier heads on the supporting heads, when the inner turret is rotatin at high speed. The shoes are of sucient length-to brid e the spaces between the sections of the gui e track.

Each bobbin 25 of the inner series is rovided at-its outer end with a ratchet w eel 36; and pivoted on each shuttle plate 28 is a locking pawl 37 which is held yieldingly in engagement with the ratchet wheel by light spring 38. The lookin pawl is formed with an outwardly exten ing thread engaging arm 39. The thread from-the bobbin passes around a ri id guide pin 40 mounted on one of the si e bars27 and then around the thread enga ing arm 39 and thence tothe thread gui ing lip 32 of the cover plate. From the lip 32 the thread passes directly up to the braiding point, as shown clearly in Figs. 1 and 2; The locking pawl 37 holds the bobbins against rotation. When, however the tension on the thread is suliicient to swing the locking pawl out of engagement with the ratchet wheel, the bob bin will turn and release a supply o f thread. The tension s rings 38 will then swin the locking pawl ack into engagement with the ratchet wheel. In this way a too free rotation of the bobbin 25 is prevented.

Rigidly mounted on the base of the ma-V chine is a ring41. Secured to this ring is a series of upwardly extendin `stationary thread guides 42. These threa guides are so arranged that they extend up into the arched supports, 12, as clearly shown in Fig. 2, the upper ends of said guides rising to a point slightly above the horizontaly center line of the shuttle plates 28. The thread guides are inclined on their outer surfaces and serve to engage the threads from the outer series of bobbins and lift them above the points of the shuttle plates 28 in order to insure said threads passing over said plates and `consequently over the outer series of bobbins. They are .ary threa located in the desired positions around the supporting ring 41 in order to secure the desire over an braiding threads. These stationary thread guides are .clearly shown and described in my Patent 1,465,554, granted Au 21, 1923.

Secured to the lower margin o the turret plate 11 is a series of outwardly and upwardl1 extending thread guides 43. These threa guides 43 are located between the arched supports 12 and coincident with the open spaces 35 between the guide track sec# tions 34. Each guide 43 is provided with a notch or depression to `receive the thread 14" from the outer bobbin 14. These notches under arrangement of the arel slightly below the vpointed ends of the l thread guides 42. The spaces 35 are provided in the dguide track to permit the stationuides 42 to carry the threads 14 outwardly yond said track and over the shuttle lates 28. The threads from the outer bo bins pass through suitable thread guides and tension devices 44 and 45; and rom the thread guides and tension devices 45 the threads pass directly to -the notches in the thread guides 43.

In operation the inner turret carrying the inner series of bobbins rotates in the direction indicated by the arrow a: in Fig. 1; and the lower turret carrying the outer series of bobbins rotates in the direction indicated by the arrow y. The supportin disks 23 are rotated through pinions 20 an crown gear 21. The carrier heads 26 are supported at all times by their engaged supporting disks. y The notches 24 in the supportin disks are so placed and the rotation of sai disks 'is so timed that when the threads 14a from the outer series of bobbins rest in the notches'of the thread guides 43 said threads will be received in the notches 24 of the supporting disks and carried under the carrier heads 26. At the same time the shuttle plates 28 are diverting the threads 14a under said shuttleplates so that the threads 14a will pass freel under the inner series of bobbins. When t e threads 14a are engaged by the stationary thread guides 42 said threads also will be engaged within the free notches 24 of the supporting disks andA als' The movement of the threads 14a (around the carrier head 26 is illustrated diagrammatically in Figs. 12 to 16 inclusive. Three threads are shown and for convenience of reference they are lettered a, b and c. The supporting disks D and E rotate in the directions indicated by their arrow. The direction of movement of the supporting disks and their attached carriers around the machine is indicated by the arrow Referring to Fig. 12, the threads a and c are in position to be engaged by the stationary thread guides 42 and'lifted away from the supporting disks and caused to travel up over the carrier heads A and C. The thread b is engaged in the notch of the thread guide 43, and the shuttle plate 28 of the carrier head B, moving in the direction of the arrow causessaid thread I) to pass under said shuttle plate and the head B. The disk D is rotating in the direction indicated by its arrow and the notch in said disk receives the thread b and permits it to pass under the head B. The rotation of the disk D is so timed that the thread will pass under the head B practically without contact with the disk D. Thel purpose of notching the supporting disks and rotating them is to provide a tree path for the threads from the outer set of bobbins to pass under the heads of the inner bobbins. The positions of the threads a and c traveling over the carrier heads and the thread b traveling under the carrier head are shown in Fig. 13. In Fig. 14 the threads have made one half of their movement around the carrier heads. The thread b has passed out of the notch of the carrier disk D and is about to enter the notch 24 of the adjoining carrier disk E. In Fig. 15 the threads are shown as completing their travel around the carrier heads. In Fig. 16 the movement of the threads around the carrier heads is complete. movement over the carrier head A and is in position to enter one of the notches in the supporting disk D. The thread b has completed its movement under the carrier head li and is in position to be picked up by one of the stationary thread guides 42 and caused to travel over the carrier head C. This over and under movement of the threads from the'outer bobbins is continuous around the entire series of inner carriers and their supporting disks. When the threads 14a are in positions illustrated in Figs. 1, 3 and 12 they extend in a straight line from the notches of the thread guides 43 directly to the braiding point. They lie slightly within the notches 24 of the supporting disks and directly between the ends of adjoining carrier heads 26. In this position they are easily diverted under the carrier heads 26 through the movement of The thread a has completed itsA the shuttle plates 28, and over the shuttle plates and the carrier heads of the inner series of bobbins by the stationary thread guides 42.

It is manifest from the foregoing that there are no reciprocating parts 1n the machine. There is no track on which the carrier of the inner series of bobbins operate. A small part only of the supporting disks are in engagement with the carrier heads so that the friction between these engaging parts will be slight. It is manifest therefore that a machine constructed in accordance with this invention may be operated at very high speeds without noise and without undue wear on the parts and with little or no strain on the braiding threads.

When the machine is used for braiding a cover over a core, the core passes upwardly through the tubular post 2 and the braiding structure is wound over the take up wheel mounted above the machine, as illustrated in Fig. 2. The braiding threads are united at the braiding point just above the spider 17 and the spider arms are so shaped that they will not, in any way, in` terfere with the movement of the threads during the braiding operation.

The supporting disks and the bobbins of the inner series may be arranged at any desired or desirable angle with respect to the braiding point; and the bobbins of the outer series may be supported and rotated in any suitable manner.
