Definitions

  • This invention relates to braiding machines and has for an object the provision of an improved braiding machine of the type in which braiding carriers are moved in intersecting sinuous paths by means of v rotating drivers with devices which hold the respective carriers against the drivers at their peripheries through a portion of their rotation, and which release the carriers at 1 appropriate transfer regions where a carrier is passed from one driver to another and is thereby carried in a rev'erscly curved part of the sinuous path until the carrier is again transferred to the next driver of the series, and so on throughout the system of drivers.
  • An object ofthe invention is to provide the carriers with terminal flanges adapted to be held in recessesnear the upper faces of the actuating drivers, and to be gripped therein by means carried on the hubs of the drivers, and acting to force the flanges against the under surfaces of removable plates covering the recesses, the machine being organized to permit unusually ready removal of the carriers for purposes of changing the carriers or inspecting the underlying parts without undue disorganization of the machine.
  • Another object of the invention is to provide holding devices for the above purpose in the form of dogs pivoted upon the hubs of the drivers in such balanced position as to be normally given a bias by centrifugal force and gravity away from holding position, and to provide means in the form of annular cams co-axially disposed adjacent to the drivers and adapted to force the dogs positively into holding position, so that the dogs are quick-acting and sensitive in their operations and constitute effective holding I devices which do not get out of order nor deteriorate rapidly, but operatewvith uniform regularity and are more reliable in action than existing devices for thepurpose.
  • Another object is to permit the use of cams which can be formed inexpensively to effect the desired movements of the carriers, and which can be exchangedquickly to produce different types of product. 4
  • Another object of the invention is to provide a machine adaptable to the manufacture of a wide variety of products, includingflat and tubular braids ortapes, and which can be used in the production of such different articles as flat wire tape for tire beads, sheathing for insulated electrical conductors and delicate ric-rac in diverse patterns.
  • Still another object is to provide a machine which can be operated reliably at extremely high speeds and with a minimum of friction Hill noise, by operators of less than average s ill.
  • the rovision 01 means to eifect automatically t e thorough and continuous lubrication of the operating instrumentalities, and to prevent soiling of the product by the lubricant; a cognate object being the organization of the operating parts, and the lubricant circulating devices, in such a manner as to concentrate the fluff or fibres given off by certain materials and to utilize the same as a filter for the lubricant.
  • Anotherobject is to provide an extremely sensitive detector mechanism adapted to stop the machine quickly upon failure of the sup ply or upon arrivalof a defectiveportion of thread, before the defect can result in a flaw in the final product.
  • Fig. 1 is a view in vertical section of a braiding machine in the construction of which the invention has been embodied, with parts shown in elevation Fig.2 is a horizontal section on the line 22 of Fig. 1, upon an enlarged scale.
  • Fig. 3 is a fragmentary, detail view in side elevation of the headof the machine shown .in Fig. 1.

  • a series of carrier driver disks is provided for actuation by the gears 16 and 18, and of these disks there'may be any suitable number, eight being shown in the illustrated embodiment, numbered 21 to 28, these disks being supported in such a manner as to permit the attach mentto their upper faces of flanged carrier members 6 to b", in the manner best understood by reference to Fig. 4,'which'illustrates also a preferred type of braiderunit sup ported by the carrier Z2 and designated generally by thereference character B.
  • driver disks 22 to 27 are preferablyof substantially identical construction throughout the series, and similarly connected with their respective gears 16, so that the following description of the now preferred form of structure associated with the driver disk 22 will serve as a description of each.
  • the driver 22 is preferably fo'med integrally with a hub 30 co-aXial with the gear 7 16, and is provided with four arcuate peripheralrecesses 32 to receive the flange 33 with which each of the carrier members 6 to Z)" is provided, so that as each carrier flange engages with one of the transfer disks its flange '33 enters one of these arcuate recesses 32 and fits snugly against the curved wall 31 thereof, being embraced between the driver 22 and a cover plate 22, the latter having its periphery cut away at 34 to clear the central post or neck b' of the carrier.
  • means are provided to hold the carrier positively against the disk 22'while the same rotates from the transfer point at which it receives the carrier to the transfer polnt at which the disk passes the carrier on e to the adjacent disk, where the carrier is re leased and is picked up by the adjacent disk and is there held by similar positively acting means.
  • the now preferred form of holding means comprises two sets of dogs 35 and 36 mounted on pivots 39 in radial slots 37 and 38 formed in the-hub 30 of the gear 16, the dogs being formed with yokes in which are anti-friction rollers-40 adapted to run upon a cam 41 mounted upon a stationary plate 112 extending horizontally across the casing.
  • All of t iese dogs are preferably so formed that by the action of centrifugal force and gravity they will be given a bias downwardly away from the flanges 33 of the carriers, tending normally to occupy the position oi the dog 35 in Fig. 4, and in pursuance of .the invention the cam 41 is provided with annular face tracks '53 and 55, of a. contour respectively adapted to force the dogs 35 and 36 upwardly into the position shown in Fig. 4'at 36.
  • dogs 35 have the dogs 35 control the transfers of carriers outward bound from the disk 21, while the dogs 36 control the transfers of carriers bound toward the disk 21.
  • dogs 35 arespaced 90apart in their slots 37 and the dogs 36 are spaced 90apartin the slots 38.

  • the ratio of the gear 61 to gear 62 is two and one half to one, so that the slide 57, and
  • each dog 44 is raised and lowered once upon each complete rota.- tion of the disk.
  • the disks 21 and, 28 may be provided with a different number-of dogs than that shown, and the gear-ratio will be then varied according to the work to be performed.
  • the casing 1 serves as a reservoir for fluid lubricant, 70, which preferably is maintained at a height sufficient to reach the gears 11, 16 and 18, which accordingly derive their lubrication directly therefrom.
  • the hubs 30 and 47 are preferably channelled, as at'71 and 72, to give access of the lubricant to the bearing studs 17 and 73, and the latter are provided with spiral channels 74, terminating in peripheralgrooves 75 to which the lubricant elevated by the'rotation of hubs 30 and 48, passing from the grooves 75 to channels 76 by which it is conveyed by centrifugal force to the carrier seats 32 and thence flows by gravity down over the dogs 35-, 36,44 and the cam tracks 50, 52, 53, 55 and their associatedparts, includin the slide 57, gears 61 and 62, etc., so that a the co-act-ing parts are constantly'flushed with lubricant,- automatically.
