BALL-IFRENG-E MAOHENE.

Application filed July 8, 1927. Serial No. 204,314.

This invention relates to machines for making what is commonly known as ball fringe i. e. a tape having a series of loops extending laterally from one of its edges and spaced at predetermined intervals longitudinally of the tape; each loop supporting a ball consisting of a plurality of strands of soft twisted yarn bound together at the common center of the ball by a wire, or other securing means, which also passes through the aforesaid loop and secures the ball to the loop.

With machines in general use at the present time,it is necessary to feed the tape to the ball making and securing mechanism by hand, placing each individual loop on what is known as the forming horn of the machine. This operation is necessarily slow, therefore, the production of fringe on any given machine is low, and further necessitates a separate operator for each machine.

The principal object of my invention is to replace the manual tape feeding operation by automatic mechanism for successively placing the loops on the forming horn, re-

' moving the loop, with a finished ball attached thereto, from the horn, and automatically advancing the tape to permit the efiicient accomplishment of these operations.

In the tape in general use, the threads forming the two sides of the respective loops lie in the same general plane, which is sub stantially common with the plane of the body of the tape. With this formation of the tape, the adoption of automatic mechanism for feeding the tape and automatically placthe loops on the ball forming horn would be practically impossible. I have overcome this objection, by producing a tape in which the general plane of the loop extends substantially at right angles to the plane of the body of the tape, and which forms the subject matter of a co-pending application, Serial No. 152,391. filed December 3, 1926.

In the hand fed machine, the ball forming horn was of a curved construction to facilitate the manual placing of the loops on the horn. I have replaced this curved forming horn with a straight horn.

The details of my invention will be fully disclosed hereinafter,reference being had to the accompanying drawings, of which 1 a plan view of a ball fringe ma.- chine having my automatic feeding mechaattached thereto;

Fig. 2 is a front elevation of the machine shown in Fig. 1;

Fig. 3 is an enlarged plan view of the feeding mechanism, forming the subject of the present application Fig. d is a sectional elevation taken on the line 1-4, Fig. 3;

Figs. 5 and 6 are sectional elevations of various details of the machine;

Figs. 7 to 14 inclusive are plan views illustrating the various successive operations effected during the formation of a ball and the removal of the loop which supports the finished ball from the forming horn; and

Figs. 7 to 1 1 inclusive are elevational views of the mechanism shown in and corresponding to Figs. 7 to 14 respectively.

Referring to Figs. 1 to 5 of the drawings, the main rigid frame or bed plate of a ball frin e machine is illustrated at 1, being provided with a plurality of bearings 2, 3, l, 5, 6 and 7. A main operating and cam shaft 10 is rotatably mounted in the bearings 2 and 3. A. second cam shaft 11 is rotatably mounted in the bearings d and 5, parallel to the shaft 10. A connecting cam shaft 12 is rotatably mounted in the bearings 6 and 7 and extends at right angles to, and between the shafts 10 and 11. The shafts 10 and 12 are connected by a pair of cooperating mitre gears 13 and 14, and the shafts 11 and 12 are connected by a pair of cooperating mit-re gears 15 and 16.

In a bearing 20, formed adjacent the front edge of the rigid frame 1 intermediate the cam shafts 10 and 11, is slidably mounted a vertically movable hollow post 21 having a head 22 rigidly secured to its upper end, and a collar 23 rigidly secured to its lower end. Levers 24, 2d are pivoted at 2st to depending extensions of the rigid frame 1. The levers 24; are each pivotally connected at one of its ends to the collar 23, and at its opposite end to a bifurcated link 25. The forks of the bifurcated link 25 are slotted at- 26 for the accommodation of the cam shaft 12, which is provided with a cam 27 engaging a roller 28 rotatably mounted in the link 25 intermediate the forks thereof. Rotation of the shaft- 12 will lower the post 21 in its bearing 20. A spring 29 is adapted to raise the post 21, and maintain the roller 28 in operative contact with the cam 27.

The post head 22 is provided with integral ateral extensions and 31, which form guideways for the following ball V forming mechanisms. r

Slidably mounted in the extension 301s a ball forming plate 35, provided at its inner end, adjacent the post 21, with a pairof parallel longitudinally extending horns 3G and 37.

and 3? are convergent, fori'ning a threat 38 therebetween into which the loosely twisted strands of ball forming yarn e are adapted to be pressed; The convergent edges of the horns 86 and are each provided witha wire receivin roove 39 and d0 respective ly, which extends along said convergent edge from the point of the respective horn into the said throat and therearound toa point within the opposite convergent edge, the two grooves, at the points of the horns, lying in a substantially horizontal plane, and the portions of the groove within the jacent substantially horizontal planes, parallel one with the other.

The horn 87 is adapted to receive, successively, the loops y of the fringe, the tape body 1? thereof being fed past saidhorn in sub stantially a horizontal'plane; the loops y occupying a vertical plane permits them to be slipped over the horn 37 as the tape 40 is advanced relative to the horn; A cooperatingpresser plate 41 is slidably mounted in the extension 31 of the post head 21, and is provided with a curved end 42 in which is formed a horizontal wire engaging groove 43.

The ball forming plate 35 is provided witl ahead 4% engaged and operated by a cam 45 on the cam shaft 10, a spring 46 return ing the plate to its normal inoperative posi vtion. The presser plate ll is provided with a similar head l? engaged by a cam 48 on the cam shaft 11, 'a spring s19 returning this plate to its normal inoperative position.

ll igidly secured to the upper face of the bed plate 1 is a bracketht), to which is secured a guide 51 for the ball forming yarn z, a spring wire 52 acting as a brake against the said yarn to retainit in any position to which it may be moved in the guideSL.

The yarn 2 passes through an eye 53 formed in an arm 54. V

The arm 54 is pivoted 05 to a bracket SG'i-igidly secured to the bed plate 1. One

end of the arm i i operatively engages the head 5''? of a vertically movable anvil which is slidably mounted in the bracket 50. The opposite end of arm 5% is engaged by an operating cam 59 securedto the cam shaft 10 by means of which the anvil 58 islowered,

The inner adjacent edges of theliorns' throat lying in ada hardened steel bushing 61 rigidly held in the bracket 50. The bushing 61 acts as one element of'a shear, for cutting the continuous length of wireinto short pieces of predetermined length, the other element of the shear comprises a blade 62 slidably mounted in the head extension 81. A pin 63 extends downwardly from the blade 62, through the head extension 31, and is engaged by one end of a bar (5 f slidably mounted, in a guiceway (35 on the bed plate 1. The opposite end of the sliding bar 64 is provided with a head (36 engaged by a cam 67 on the cam shaft 11, which moves the blade 62 in a direction to cooperate with the hardened steelbushing fil to shear the wire, a spring 68 returning these elements to-theii' normal positions and maintaining the bar head 66 in operative contact with the cam 67. I v. v

The wire to is fed forward a predetermined distance tomeasurethe length of a portion thereof sullicient to form one of the ball taining rings, by a. cam 70 secured to the cam shaft 12, which engages a lug 71 on a wire feedinghead 72, slidably mounted on the bed plate 1. The wire feeding head 72 comprises a substantially rigid finger 73 and a relatively movable finger 74, by means of which the wire to may be gripped between the two fingers during the forward or feeding movement of the head 72 and. released therefrom during the rearward movement thereof.

The movable finger 74 is pivotally and sh'dably mounted on a horizontally disposed rod 75 supported by brackets 76, 76 secured to the bed plate 1, and has arm '4"? adapted to be held in operative"engagement with a cam 7 8 on thefca m shaft 11. v'lhe linger 73 consists of a spring plate secured at one of its ends to the under side of the arm 77 of the movable linger 74, its opposite end slidfably resting on a bracket 79 S8C1lr6Cl to the bed plate 1. The resiliency of the-spring plate comprising the finger T8 maintains the arm 77 in contactwith the cam '78.

As the cam 7 8 rotates, thearm 77 rides onto the low portion thereof permitting the finger 74 to be moved away from the finger78, due to'the resiliency of the material of which the finger 73 is composed, to release the grip on the wire 20. t the same time, a spring 80 returns the head 72 to its rearmost position, and maintains the lug 71 thereof in contact with the head advancing cam 70, on the cam shaft 12. The cam 7 8 then operates the finger 74 to again grip the wire w for a subsequent feeding of the said Wire.

v Slidably mounted within the extensions 30 and 31 respectively is a pair of ball yarn shear blades 81 and 82, each of which are provided with a vertically projecting pin 83 and 84: respectively. The pins 83 and 8e are respectively engaged byv one end of a lever 85 and 86, pivoted at 87 and 88 to the bed plate 1. The opposite end of each of the levers 85 and 86 are respectively engaged by cams 89 and 90, secured to the cam shaft 12. A spring 91 is connected at-its opposite ends to and extends between the cam engaging ends of the levers 85 and 86, thereby maintaining these arms in operative engagement with their respective cams, and tending to move the shear blades 81 and 82 to their inoperative or separated positions. I

The machine so far as described is in general use, with the exception of the straight loop receiving horn 37 of the ball forming plate 35, the loop receiving horn in the old machinesbeing of a curved construction as above noted. These old machines required the manual feeding of the tape to the machine and the placing of the loops on, and their subsequent removal from, the curved horn used in these machines, by hand.

The object of my present invention is to eliminatethese manual operations, and to provide for the automatic mechanical feeding of the tape, the automatic placing of the loops on the straight horn of my present machine, and the subsequent automatic removal of the loops from the horn with a formed ball attached to each one thereof.

The mechanism comprising the features of my invention, see Figs. 3 and 41, consists of a bearing 100 rigidly secured to the head 22 of the vertically slidable post 21. In the bearing 100 is rotatably mounted a pair of parallel shafts 101 and 102. t On one end of the shaft 101 is rigidly secured a tape feed wheel 103, and on the corresponding end of the shaft 102 is rigidly secured a presser wheel 104, between which and the feed wheel 103 the body-tape w is gripped.

The said body tape passes from a source of supply to and between a set of straightening rollers 105, 106 and 107, each of which is rotatably mounted on a common support 108, secured to the base plate 1. These rollers remove all wrinkles from the body tape :0, and arrange the said tape in a substantially .vertical plane, with the loops z thereof positioned above the tape, and are adapted to retard the advancement of the tape, thus maintaining it under tension between the gripping point of the cooperating feed and presser wheels 103, 10 1 and the set of rollers 105, 106, 107.

The tape :0 advances from the roller 107 in a vertical plane to a vertically extending guide 109, which is secured to the bed plate 1 adjacent the wheels 103, 10 1.

The tape 00, between the guide 109 and the upper side of the periphery of the feed wheel 103, is twisted from a vertical plane, at the guide 109, to a substantially horizontal plane,

at the said upper side of the periphery of the feed wheel 103. At this point the loops y, the general plane of which is at right angles .to the plane of the tape body a", are carried into the path of, and are placed on the outer end of, the straight horn 37 of the ball forming plate 35, the body tape a being sup ported by the wheel 103 in a plane extending through the center of the horn 37 and plate 35.

After passing around a portion of the periphery of the feed wheel 103 and over a portion of the periphery of the presser wheel 104, the finished fringe, consisting of the body tape with the finished balls attached to the loops y thereof, passes through the hollow post 21 to any suitable receiving receptacle.

The shaft 102 is carried in journal blocks 110, 110, slidably mounted slots 111 formed in the bearing 100 and movable therein by means of adjusting screws 112, whereby the presser wheel 10%1 may be moved with respect to the feed wheel 103 to vary the amount of pressure exerted on the tape w.

On the ends of the shafts 101, 102, opposite those occupied by the wheels 103 and 10s respectively, are gears 113 and 11 1, respectively, which intermesh and thereby effect synchronization of the rotary motions of the wheels 103, 104. The gear 114 also meshes with a gear 115, rotatably mounted on a stud 116 secured to the head 22 of the vertically movable post 21.

A ratchet wheel 117 is rigidly secured to the gear wheel 115, by means of which the gear 115 is rotated, and thereby rotates the wheels 103 and 10% in intermittent steps effecting a peripheral movement thereof, sub stantially equal to the longitudinal spaces between the loops W on the tape :0. A pawl carrier 118 is also pivotally mounted on the stud 116, and a pawl 119 is pivotally mounted on the carrier 118, being held in operative engagement with the ratchet wheel 117 by a spring 120. A spring detent 121 engages the ratchet wheel 117 and prevents back lash thereof, after the wheel has been rotated by the pawl 119.

The pawl carrier 118 is oscillated about the stud 116 by a link 122, one end of which is pivotally attached to the pawl carrier 118 and the opposite end of which is pivotally attached to one end of a lever 123. The lever 123 is pivoted at 124 to a bracket 127, rigidly secured to the base plate 1, and is provided with a rotatably mounted cam roller 126, which is engaged by a cam 125 rigidly secured to the cam shaft 10. A spring 128 maintains operative engagement between the roller 126 and the cam 127.

A stripper 130 is slidably mounted in the extension 30 of the post head 22, immediately adjacent the ball forming plate 35. The stripper 130 lies in a vertical plane between the plate 35 and the adjacentside of the tape feeding wheel 103 and is adapted to be moved horizontally for the purpose of stripping the loops g from the horn 37 after the formed ball has been attached thereto. The end of the stripper 130, opposite that which effects the stripping operation, is provided with a laterally extending pin 131, which is positioned al lnv 137 of the bell-crank lever 134 is equipped with a roller 138, engaged by a cam 139, rigidly secured to the cam shaft 10. A spring 140 maintains the roller 138 in operative engage ment with the cam 139, and withdraws the stripper 130 to its inoperative position.

A vertically extending cylinder-.141 is rigidly secured to the ri id bracket 50. A plunger 1s slidably mounted 1n the cylinder 141, and consists of a large head portion 142 of substantially the same diameterras that of the hereof the cylinder 141, and a stem 143 of, reduced diameter which projects through an aperture of substantially equal diameter thereto formed in the upper end wall of the said. cylinder. A spring 144 encircles the stem 143, and is confined in the cylinder between the head 143 of the said plunger and the said'end wall of the cylinder. A pin 145 is secured in one side of the plunger head 143, and projects through a slot 146 formed in the side of the cylinder 141, thereby limiting the movement of the plunger in the cylinder and preventing rotation of the plunger therein. The head 143' is also provided with a dependingpoint .147 which is adapted to engage the upper face'of the born 37 and thereby move the loop g into the throat 38 of the ball forming plate as this plate advances to form a fringe hall. V

In the operation of the'machine, the cam shafts 10, 11 and 12' are continuously rotating and assuming that the elements of, the machine are occupying the positions illustrated in Figs. 1 to 5 of the drawings, with a loop y] on the outer end of the hornj37, the

alun 'er 21 head 22 and the head extensions 7 30 and 31 will be raised until the ball form-- ing slate 35, carried by the extension 30, and the opposing presser plate 41, carried by the extension 31, are in a horizontal plane coincident with that of the center of the hardened steel bushing 61, through which the wire 10 is being advanced'bythe wire feeding head 72. The anvil 58 is lowered to a'position immediately adjacent the projecting portion ofthe wire w, between the said wire and the ball yarn a. The ball forming yarn 2 now lies between the horns 36 and 37 (see Figs]? and 7 The point 147 of the plunger 1.43 is in. engagement with the upper face of the horn 37, between the loop 9 and the end of the horn. The'presser plate 41 then advances toward the wire to, the wirew lying within the horizontal groove 43 in the curved end 42 thereof. The wire to is now pressed against the anvil 58 by the presser plate 41, and the wire-shear blade .62 advances and shears the wire between its beveled edge and the side ofthe wire guiding aperture formed in the bushing 61, .(see Figs. 8 andS The presser plate continues to advance,'and' thereby bends the wire 10 around the anvil 58;withthe ends of the wire in alignmentwith thegrooves 39 and in the innerconvergent edges of the horns 36 and 37 respectively (see Figs. 9 and 9). The ball forming plate 35 new advances toward the anvil 58 and the ends of the wire 10 enter the said grooves 39 and 40, after which theanvil is withdrawn to itsinoperative position, as is thewire-shear blade 62 The ball forming yarns is now engaged by the convergent edges of the horns 36 and 37 and by the-wire to (see Figs. 10 and 10 As the plates 35 and; 41 advance toward each other, one end of the wire wenters the loop 3/ and thereafter the yarn eisforced into the throat 38 of the plate 35, the point 147 of the plunger 143 moving the loop 'y along the horn 36 into the throat 38 thereof, as the plate 35 advances. Further relative'movement of the plates 35 and 41, toward eachother, causes the ends of the wire, in following the grooves 39 and 40, to be bent completely around the yarn a, to secure the yarn to the loop (see-Figs. 11 and 11). The post '21 and the partscarried thereby are now lowered (see Figs/12 and 12) and thereby drawv the yarn 2 through the guide 51, where it is frictionally gripped by the spring 52, thus the length of the piece of yarn e which is to form a'ball is measured. The yarn shear-blades 81 and 82now advance toward each otherto cutthe measured length of ball forming yarn (see Figs, 13 and 13*).

The stripper130 then advances into engagement with the loop between the tape a: and the formed ball a, and as the shear blades 80 and 81, and the forming plate 35 and presser plate'41, recedethe stripper. 130. moves the loop y oil the horn 37, and then recedes immediately thereafter. At. thistime, the pawl carrier 118 is turned on the stud; 116 bythe cam 127, the pawl 119 engages one of the notches of the ratchet wheel 117, thereby rotating said ratchet wheel and the gear 115, which, through the gears 113 and 114, rotate the tape feed wheel-103 and presser wheel 104, to move the loop y with the formed ball a away from the forming position and positioning anew loop y in the path of and onto the end of the horn 37. The cycle of operations just described is'then repeated for the i successive formations of fringe balls and their attachment. to the loops of the tape, which forms the body of the fringe.

The operations. being entirely automatic permits the machine to be operated continuously at a considerably higher-rate of speed than permissible in a hand fed machine, and eliminates the necessity of employing an operator foreach machine, as one operator can, with ease, look after a number of theautomatic machines, thus the production on a given number of machines is greatly increased and the cost of-operation is materially reduced.
