Be it known that I, ORVILLE R. VAN

' ,Vnoirrnx, a citizen of the United States, residing at. Tompkinsville, county of Richmond and State of New York, have invented certain new and useful Improvements in .Braiding-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to braiding machines for, braiding or weaving tubular fabric.

'oneiset 0 threads or strands is led from ,tubes carried by a rotating carrier, and the other set of threads or strands are led from tub'e's carried b oppositely moving shuttles. ;,1,-. -The object o the invention is to provide a i rac-tical machine of this class which shall e. simple in construction, certain in its =-."operation, and which" shall have a large product on at a low operating speed, and wh ch,because of its slow operating speed,

. the short movements of its reciprocating parts, and its simplicity of construction, shall be comparatively noiseless in operation and shall have great durability.

As a full understanding of the invention can best be given by a detailed description of a machine embodying the various features of the invention in a preferred form,

such a description will now be given in connection with the accompanying drawlngs showing such a preferred form of machine, and in which- Figure 1 1s a side view of such 'a preferred form of machine in elevation; Fig. 2 is a plan view of the machine; Fig. 3 is a. plan vlewpartly broken away of the weavmg or braiding mechanism proper, and

BRAIDING-MACHINE.

Patented Apr. 4, 1911,

.7 is a detail sectional view of one of the shuttles and thread guides taken on the same plane as Fig. 4, but with the thread guide in its outer position; Fig. 8 is a broken view of a. portion of the'product of the machine.

Referring to the drawings, the frame of the machine comprises a central table 10 from which radial frames 11 extend outward to an outer ring 12, the whole being supported by suitable legs or standards 13. The frames 11 are preferably also connected by an intermediate ring 14. The main drivin 16 and 17 extending downward from the ring 12 at opposite sides of the machine. The shaft is-driven through a driving pulley 18 which is mounted free to rotate on the shaft and to which the shaft is clutched when desired by means of a clutch disk 19 which is keyed to slide on the shaft and normally pressed away from the driving pulley by a spri'ng 20, and '\...ich is provided with a beveled rim for enga ing the beveled inner face of the rim of tie driving pulley when the clutchdisk is forced toward the driving pulley. For forcing the clutch disk toward the driving pulley, a hand lever 21 is provided which has a U-shaped or forked end formed to engage in an annular groove in the hub of the clutch pulley, the sides of said U-shaped end being tapered off, as shown at 22, so that when the U-shaped end of the lever is moved upward the clutch pulley will be forced against the driving pulley, and when the U-shaped end of the lever is moved downward the clutch pulley will be allowed to move away from the driving pulley under the pressure of the spring 20.

A stationary cam plate 25 is mounted on the table 10, and a. circular, plate or table 26 is mounted to rotate over the table 10 and cam plate 25, and is held in position by 'means of a short central hollow shaft 27.

shaft 15 is journaled in hangers Each carrier thread passes from its tube mountedgbn a post 31" through a tension device 32,, thence past a stationary guide to a take-up .arm 38, thence to'a vibrating guide 34, and thence upward :and inward to the point where the threads are braided tofgether. 'The number of osts'31', tension dei- 'vi'ces, take-up arms, an vibrating guides ,w-ill d'e nd upon the'number of threads to endzfor: twelve thread machine in which the [threa are dividedinto two sets of six ends.

beibrai ed, The machine shown is a twelve each, and 'the 'naachine therefore i has six of the'posts- 3l .-andisiii sets of-the devices for tubes on. t

controllin'gljthe threads which pass from the fe sixfpostsa' i The shuttles 35, ofwhich 'there are six .in the machine-showman mounted to travel around and adjacent to the peripheral faceof the. rim 30 of the table or carrier 26, on a track, on the rim-of the table formed by an 'formed .with concave inner'faces curved to upper vertical flange or rib 36 and a lower flange or shoulder 37. The shuttles are correspond with'the curve. of the rim of the table 26. The lower edge of each shuttle rests on the shoulder 37, and each shuttle is formed or provided with aninwardly extending grooved .pottionwhichrhns on the upper flange or rib36. The shuttles are held downin place on the rim 30 by a projecting flange which isformedby the edges of stationary plates 39-and movable plates 40 mounted on the upper face of the table. The movableplates 40 are arranged to slide inward to ward the-center of the table from the posi-- tion sho'wn'in the drawings to permit the shuttles to be. removed, being guided by the undercut edges 41 of the stationary plates 39' and 'securedin position by set screws 42 The front end or nose a of each shuttle runs close to the face of the rim of the-table 26, and'the outer surface of each shuttle is convexly curved to form a smooth surface for the passage of the carrier threads as hereinafter described.

The shuttles are driven in the direction opposite to the rotation of the table or car-;

rier 26 by means of pnshers 45 carried by a 28 and 49 will be timed, according to their, 60.

ring 46 mounted on the outer ring 12 of the. frame and held in position by means of re movable clips or plates 47. The ring 46 carries a skeleton bevel fgear 48 which meshes with a bevel gear 49 on the driving shaft 15 at the opposite side of the machine from the gear 28, so that the ring 46 "will be driven in ,the direction'opposite to. that of the rotation of the table 26. The gears ushers 45 are of hollowedseams fdrm of the outer side of the shuttle, and;

push the shuttles by engagmg them near their:

rear ends while leavinga Shuttle and. the-pusher until the. thread reaches thefpoin't of'engagelnent between the usher and the shuttle, at'which point the readwill be in engagement with smooth pusher, and the shuttle will be forced 'slightly'forward relatively to the pusher to.

allow the thread to pass; The inwardly projecting forward end of the pusher serves .to. prevent the shuttle from running ahead of its-proper position.

i The pushers are carried by movable sec-..

converging surfaces of the shuttle and the 'ee passage for the entrance and pass ng oft-breads between the.

tions 50 of a vertical flange vhich extends upward from the ring 4E said movable sections being pivoted at tli'e endsof stationary sections 51- of saidflangey and normally held in position by 'meansof suitable fastening devices 52 at their free ends. hen the fastening device52 of any movable flange section 50 is released, the flange sect-ion 50' may be thrown/outward to carry the pusher away from the shuttle and to give access to the face of, the rim of the table or carrier 26. ,Each of the shuttles 35 carries a tube of thread or yarn, andgas shown,'has

a longitudinal chamber or recess for the tube of thread open on-the side of the shuttle which runs against-the rim of the carrier 26 and provlded'ateach endwith a supporting and positioning spring 53 arranged so that the tube of thread, may be readily pushedinto place and then rotatably sup ported by the springs 53, and that the empty tubes may be readily pulled out; The

thread passes out from the interior of the shuttle through an opening in the top wall beneath a tension spring 54 and under a guide 55 from which it passes upward and inwai d to the braiding point.

The rim of the tableor' carrier 26 is formed with a number of vertical peripheral recesses corresponding tothe number. of tube pins or posts31, and in these'recesses are mounted ,the vibrating thread uides 34. Such guides 34 are formed .with a vertical back plate and with .top and botto'nt flanges spaced a distance apart'greater tl1a-n' thc ver-- tical thickness of the shuttle and which ex-n of the shuttles and above' the. li' emf travel of the top of the shuttles respe tit tely, and the upper of which flanges is fo d.or-cut tend below the line of travelofthe bottom away to permit the passage ofthe thread. The threadpassin through each of such guides enters from the top, passes downward to a guide pin or staple 56, thence outward under agulde pin 0r staple 57, and thence upward pasta guide pin 58 from which it passes upward and inward to the-pointiof braiding. When the guides-34 are in .their v inner or retracted positiQlh a'fll owndntFigs.

2 to 5, the outer run of the will be inside of the path of movement of the shuttle noses, but when the guides are in their outward position,.as shown in Fi s. 6

and 7, the outer run of the threads wifl be outside of the path ofzmovement of the shuttle noses, so that as a shuttle and an outwardly projected guide approach .and

. pass each other, the nose of the shuttle will pass inside of the outer run of the thread carried by such guide and the thread will be drawnaround the curved outer surface of the shuttle -as shown in Fig. 7. It will be .noted that this outer run of the carrier thread between the guide pins 56 and 57 is a free run; that is, the thread is .not inclosed, but is free-or open so that it may be engaged by anddrawn out in a loop around the shuttles. The guides 34 are given their reciprocating outward and inward movements by 'means of a cam groove 60 in the up er face of the stationary cam late 25, eac 1 guide being provided with an inwardly extending stem 61 which carries a cam roll running 1n the cam groove 60. The movement of the guides 34 need be only the very short movement required to move the outer run-of the carrier thread back and forth these guides across the path of movement of the noses 'tomove the carrier thread clear across the path of movement of the body of the shuttle. The take-ups 33' o erate to pay out the carrier threads as t ey 'pass outside the shuttles and to take up the slack in the threads after they have passed around outside of the shuttles. 'llhese take-ups are formed by pivoted arms fwhich are gwen a positive-take-up movement by means of vertically sliding racks 65 jwhich engage pinionsyfa'st ,to the arms and which racks are operated by means of al vertical cam 66 on the cam plate 25, the racks being shown as provided with cam roll: running on the"face of such cam. The can (56 is formed and timed to correspond with the cam 60 and with the travel of the shuttles, so that after the guides 34 have been projected to their outer positions and when the front end of the shuttles are passing the guides, the takea up armswill moved forward and downward to give the necessary slack to permit the carrier tlneads to pass around the shuttles, and as the shuttles pass beyond the guides thetake-up arms will be positively raised'to take up the slack. In the machine shown, which weaves the threads in a simple overand"underjor basket stitch, cum ()0 is formed to project and retract the recipro I eating guides 34 in unison and in time with the meetings 'of the guides and the shuttles so that the shuttles will pass alternately all outside and then all inside of the carrier threads, each'shu'ttle passing alternately inside and outside of successively carrier threa'ds.

The tension devices 32 maybe of any suitable form. An ad'usta-ble tension device,

such as shown, is pre erred.

The .wire, cable or other article or form about which the threads are to be braided is fed upwa rd through the hollow shaft 27 to and past the braldin point. The machine shown is intended ior braidin a covering on an electric conductor or cahle, and

is rovided with means for 1iding andv fee in the conductor or ea le upward throng the machine comprrsln a lower guide wheel 70 carried by brac tets below the plate 10 and an upper feeding and guidin wheel 71 which is driven from the driving shaft 15 through miter gears 72, vertical shaft 73, worm 74,, worm gear 75, gears 76, 77 and 78, and gear-7a, meshing with a ear 80 on the shaft of the guide and feeding wheel 71. Such gearing is timed to cause the conductor or cable to move upward at the desired speed relatively to the speed of the weaving-mechanism, and accordin to the desired character of the weave. he gears 76 and 7 8 are preferably change gears to permitof variation in thespee movement'iof the cable or conductor, and to provide, for

the gear 77 for adjustment of. V ars 76 and 7.8 of difierent sizes, the gear 7 is carried by an adjust-' able arm 81 mounted to swing about the axis-of the gear 78 and held in its adjusted position by means ofa bolt and. nut cooperatin with a slotted downwardly extending ranch 82 of the arm 81, and the shaft of the gear 77 is mounted to be adjustable in a longitudinal slot in the arm 81.

In the o eration of, the machine, the carrier threa s being threaded from the tubes on the pins or osts 31 through the res ective tension (evices, take-up arms andr ci rocating guides, and thence upward to the raiding point, and the shuttle threads passin from the guides on the shuttles upwar to the braidingpoint, the carrier or table 26 is rotated in the direction of the arrow in Fig. 3, and the shuttles are driven in the opposite direction to make successive revolutions in time with the rotations of the carrier 26. The guides 34 through the operation of the stationary cam 60 are reciprocated in unison and in time with the movement of the shuttles so that as the shut tles pass the guides, the outer run of the carrier thread in each guide is presented alternately insideand outside oft-he path of is indicated by Fig. 8.

If it is desired to have the machine operate as a circular loom, that is to cause the shuttle threads to interweave with threads from tubes or bobbins on non-rotating supports, it is only necessary to have the table 26 remain stationary and cause the cam disk to rotate in either direction .at half the angularveloeity of the shuttles. \Vith'the machine operatin in this-way, one set of threads in the joduct will extend longif; tudinally of th fabric and the otherset'rof 9' It will be understood that instead of have 1 threads will run spirally aroundthe fabric.
