BRAID'ING-MACHINE.

7'0 all whom it may concern:

`Be it known that I, VICTOR BEAUREGARD, a citizen of the United States, residing at New York city, in the` county of New York and State Aof New York, have invented new and useful Improvements in Braiding-Macbi'nes, of which the following is a specification. i

This invention .relates to an improvement in braiding machines, ofthat class in which strips of sheet materiall are braided into the form of a tube, and the objects are, first. to provide a si1nplecheap, and durable machine for tubular braiding in which strips of sheet material, such, for instance, as paper fiber may be braided into tubular form; second` to prevent the strands from catching and tearing off when they pass 'over one another; third, to maintain a substantially uniform tension on the portions of the strands which intervene between the reels and the pointI of braiding; fourth, to provide devices to lock the reels against backward rotatiouwhen strands become broken; and fifth, to provide feeding mechanism which shall not crush nor distort the tubular fabric and which shall feed said fabric at a constant uniform rate of speed, @aid feed being readily adjustable by the operator.

lhe invention consists vin the combination and arrangement ef parts set forth in the followingl specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a plan view of my improved braiding machine. Fig. 2 is a section, partly in elevation, online 2 2 of Fig. 1, looking in the direction of the arrows on said line. Fig. 3 is an enlarged detail plan section-taken on line 3 3of Fig. 2. Fig. 4 is a section, partly in elevation, on line 4 4 of Fig. l, looking in the direction of thearrows on said line. Fig. 5 is an enlarged side elevation of one of the reels, together wthla reel standard andreel carrier. Fig. 6 isa detail sectional elevation of a portion of the parts illustrated in Fig. 5, partly broken away and with a portion of the reel standard yindicated in dotted lines. Fig; 7 is a plan section on line 7 7 of Fig. 5. Fig. 8 is a section, partly infelevation, taken on line 8 8 of Fig. 5, looking toward the right in said figure. Fig. 9 is an enlarged detail section, partly in elevation and partly brokenaway, en line 2 2 of Fig. 1, looking in the direction of the arrows in said figure. p

.l Like numerals refer to like parts throughout the several views of the drawings.

In the drawings is a guide-plate provided with sinuous intersecting guide slots 16 and 17. The guidef plate 15 is also provided with recesses' 18, 19, 20, 21, 22, 23, 24 and 25 formed therein. Stationary shafts 26` 27, 28, 29, 30, 31, 32 and 33 extend upwardly within the recesses 18, 19,-20, 21'; 2223, 24 ,and 25, respectively. Spur gears 34, 35, 36, 37, 38, 39, 40and 41 are journaled on the shafts 26, 27, 28, 29, 30, 31,- 32 and 33, respec- Specification of Letters Patent. i Application and March 19,1906. serai No. 306,738.

A series of four. reel'carriers 53. all identical in construction engage the slot 1.6 and are adapted to travel therein. A series of four rcel carriers 54, all identical in construction, are adapted to travel in the guide-slot 17. The series of reel carriers 53 is moved Each of the reel standards 57 has a shaft 60 journaled i therein; A 'reel 61, consisting of plates 62 and 63, is

the shaft 60,

is provided with pins 66 by which said ratchet may be moved rotatively. A coil spring 67, fast at one end to the shaft 60 and at the-other to the winding ratchet 65, acts to normally move the shaft 60 in the direction of the arrow c l(Fig. 5). The tension of said spring may be adjusted by moving said winding ratchet 65- in the direction of the arrow rl (Fig. 5), a stoplpawl 68 acting to hold said ratchet" in its adjusted position. 69, journaled on the shaft 60, has wound thereon a strip of paper fiber in the form of a roll, .the inner end of said roll being fastened to said disk. thumb-nut 70 A' disk the shaft 60 'may be adjusted nsaid shaft to cause the reel plate 62 to bear with more or less pressure upon the disk 69 n. A brakedrum 71 is pinned to the disk 69and moves rotatively" fand'rotateswith the -rsel plate 63vby reason of a stud 73 which passes through said ratchet and said reelplate. A brake-band 74, preferably formed of very thin sheet v metal, surrounds the brake-drum 71 and both ends of i said brake-band are inserted-in a jaw' 75 formed inthe stud 73, as illustrated in Figs. 5, 6 and 8. It will be' pressed stop 78. A helical extension spring 79, fastatV one end to the brakegarm 7 6`and 'atlthe other end to the ratchet 72, acts to hold the end 77 of said brake-arm in contactwith the stop 78.

In the lnormal operation of the machine the tension of the strand 80, leading ,from the reel 61, acts" to hold the end '77 of the brake-arm 76 against the stop 78 With such force as to overcome the tension of thespring' 7 9' sullicientlyito allow the brake-arm 76 to be swung toward theright (Figs. and 6)-thereby holding the brake-band 74 loosely around the brake-drum 71. If

the friction oi the reel plate 62 against the disk 69 and a the roll of fiber, should not be great enough, or, 'if the viblation of Athe machine should cause a slipping oi saidroll of fiber faster than the strand leading therefrom istaken'up by the braiding process, the-tension of the spring 67 would become diminished by atendency to left-handed rotation of the shaft 62 in'the na-V v ture of a gradual slipping of the reelplate 62against said disk and roll, if it were, not for the brake hereinbelore described. 'ShoulfLsuch a slipping occur beyond the normal slipping, 'due to theunwinding of the roll in' the process of braiding, the tension upon the strand .80 becomes diminished to such an extent that the end 77 ofthebrake arm76 has a tendency to move away from the stop 78, but said end being held in contact `with said stop by the spring 79, the reel plate 63,

through which the stud 73 passes, moves very slightly in the direction of the arrow f(Fig. 6), thus `causing said stud to be rocked in the direction o the arrow e (Fig. 6) by the pull ofA the spring 79 upon the brakearm 76, thus causing the brake-band 74 to grip the of fiber thereon, against rotation until in the'operation.

of braiding the slack hereinbefore mentioned has been l taken up and the normal tension on the strand has been restored, whereupon the friction of said roll of fiber against the reel plate 63 acts to-move said reel pla-te in the direction of the arrow g (Fig. 6) with suicient force to cause the end 77 of the brake-arm 76 to boar against the stop 78 with its normal pressure, thus causing the brake-band 74 to become loosened from the brakdrupi 71, whereupon the roll oi fiber resumes its normal slipping with relation to the reel 61.'

The. re'el standard 57 is provided with an arm 81 formed integral therewith. A guide-finger 82, pivoted at 83 to the arm 81, 1s provided with guide-pins 84 and S5. between which the strand 80 passes. The

arm 81 is provided with pins 86 and 87 through which ,ratchet 72. It', however, the strand 80 should become 4ranged to slide within the hollow post 91. and fast connected vto the gu ide-finger 82 by a link 90. `While Athe strand 80 is under' tension, the gi1idetinger 8,2 acting onthe link and the stop-pawl 88 Aacts to hold said .sto'p-pawl out of engagement with the severed, the right hand'end of the guide-finger 82 (Fig. 5) drops of its own weight to thel position shown' in dotted lines, thereby causing the 'stop-pawl `8b to engage the ratchet '72, lockingth'e reel`61. against backward rotation. It will be understood that the. reel mechanisms are all identical in' construction and that the foregoing description applies to them all.

A'hollow post 91. is lprovidedvat its upper end with a stationary ring 92 iast thereto. A tubo 93 is ar- 1 thereto is a stud 94 on which is jonrnaled a ca1nroll 95. A cam 96,v journaled on the exterior of the hollow .l post 91,',is provided with an undulatory face 97 which f engages the ycam-roll 95. AA grooved pulley98, vtermed integral with the cam 96, is driven by a roundbelt 99 irom-a'grooved'pulley 100 last to the shaft 43. The

.rotation of the cam 96 acts to impart a vertical reciprocatory movement to the tube 93. A movable ring 101 is Iformed integral with the tube 93. The'stationary ring 92- is provided with' slots 102 which register with 'slots 103 formed in 'the tube 93. -Through those slots Aextend presser arms'104 providedwith presser rolls 105, journaled on said arms.l I flhepresser arms 104 are pivoted at 125 to a vcollar 106 surrounding the post 91 and fasttheret'o. Adjusting screws 107, having screw-threaded engagement with the collarlO,

are provided with collars 108 fast thereto. Helical compression springs 109 bear'at theirl lower ends againslthe collars 108 'and at their upper ends against the presser arms 104 which are slotted to receive the ad-l justing screws 107. The presser arms 104 may b adjusted .by turning the handles 110 of the adjustingscrews 107. W.. 'j i Extendingupwardlyl from the guide-plate 15 are4 posts 111 Aand 112 `on which is'mounteda frame-,113. A vertical shaft 114 is journaled in the frame 11.3 and has fast to its upper end a sprocket-wheel 115 and to its lower end a tapered mandrel 1.16,l said mandrel being provided with a screw-thread upon which to braid the fabric. 'The sprocket-wheelV 1145 -is driven by a chain 117 from a 'sprocket-wheel -118 fast to a vertical shalt 119. The shaftf119 isljournaled in bearings in the frame 113 and the'guide-plate 15,'respectively, and is driven by a gear-120 'whichrneshes Vinto the gear 42.;- The tension of the chain 117 is maintained by an idler roll 121 journaled on an'idler arm 1 22, said arm being adjustably mouhtedon the frame 113.

The operation' is'as follows: Starting with the `part- Yshown in the posit-ions` illustratedin Figs. l and 2, the

strands 80 leading from thereels l'having'- been pre- 120 viously braided upon the mandrel 116, the sries of reel carriers 53, together withl lthe reels-and mechanism thereon, are moved'in the guide-slot '16 in the direction of the arrows a,while the reel carriers 54,

together with` the 'reels and mechanism thereon`,are` 12 5 ing on the mandrel 116. The reel standards 57 are 130 free to swivel upon their respective reel carriers, and

by reason of the, strands 80 leading therefrom through the guide-fingers 82 are, maintained in their radial relation'to thecenter ofthe-mandrel IlGV-t'hat is, the

axis-of each reel is at' all times at right angles to a plane in which .the median axial line ot`- said .mandrel and the median axial line of the spindle 58 are located.

As the'tubular fabric is braided on the mandrel 11.6 it is fed downwardly therefrom by the rotation of said mandrel, Its rate of feed may be `governed by adjusting the presser rolls 105 with more or less pressure against said fabric. The braided fabric passes downwardly through the tube 93 and from thence may be carried through thev flooring and rolled up' upon any suitable reel (notAshoWn). As the strands 80 cross yand re-cross on the stationary ring 92, any tendency which they may have to catch on the edges of each other is overcome by the movable ring 10] which is reciprocated vertically, .as hereinbeiore described, and which imparts to the portions of the strands which intervene between the guide-fingers 82 and the mandrel-11G a very rapid vertical vibratory movement.
