12 Claims. 1

This invention relates to a cable lashing machine such as used for securing aerial cable to a messenger or supporting strand and has for its principal object to provide a machine of this character for spinning a plurality of lashing wires about a supporting strand and one or more aerial cables to be supported thereby.

Other objects of the invention are to provide a cable lashing machine having a streamlined, light-weight construction which is easily handled and applied in working position on a messenger; to provide a lashing machine with a spinning head carrying a plurality of lashing wire reels and which is rotatable about the spinning axis through driving mechanisms actuated by the lay of each lashing wire progressively with movement of the machine along a messen'ger; and to provide a lashing machine having a substantially balanced spinning head to effect uniform tension and lay of the lashing wires.

Further objects of the invention are to provide a spinning head in which the housings for the driving mechanisms and reels enhance the structural strength of the head for reducing Weight; to provide a lashing machine with roller guides arranged in V formation to support the aerial cables in proper relative relation while they are being lashed to a messenger; to provide differential adjustment of the guide and supporting rollers through ratchet locks; to provide a lashing machine with a no back mechanism for holding tension on the lashing wires; to provide for ground release of the no back mechanism when desired; to provide the lashing machine With a carrying handle; and to provide a safety lock that is manipulated through the handle for locking the spinning head from rotation on its carriage or trolley while the machine is being transported or applied in working position.

In accomplishing these and other objects of the invention, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawings wherein:

Referring more in .detail to the drawings:

l designates a cable lashing machine embodying the features of the present invention and which is adapted for lashing one or a plurality of aerial cables, for example, three, designated A, B and C to a supporting strand or messenger D by means of spirally spun lashing wires E and F as shown in Fig. l.

The lashing machine includes a trolley 2 comprising a cylindrical body 3 forming a longitudinal passageway 4 having radially directed annular flanges 5 and 5 at the respective ends thereof mounting ring-shaped heads 'I and 8 respectively. The cylindrical body has a longitudinal gap or throat 9 connected with the passageway 4 and registered with openings ii) and H the heads I and 3 to pass the machine over a messenger and the cables to be lashed thereto as later described.

The front head 8 has a forwardly projecting flange i2 framing the end opening and gap of the cylindrical body. Project-ing forwardly from the flange in diametrically opposed relation with the gap are spaced apart extensions l3 and it to accommodate a trolley wheel therebetween. The trolley wheel is fixed on a shaft it having the ends rotatably mounted in bearings ll carried by the respective extensions l3 and I i as best shown in Figs. 2, 8 and 10. One end of the shaft I6 projects through its bearing and carries a ratchet wheel 18 having circumferentially arranged teeth i9 adapted to be engaged by the 3 tooth 28 of a pawl 2i. The pawl 2| is pivotally mounted on a pin 22 that is carried by a bracket 23 secured to the end plate 8 as best shown in Fig. 11. The pawl projects forwardly over the ratchet wheel and is connected by a spring 24 with the extension 14 so as to retain the tooth 28 thereof in contact with the teeth H! of the ratchet wheel ii! for preventing reverse rotation of the trolley wheel l5. The pawl, however, permits rotation of the trolley wheel in a forward direction since the teeth l9 are shaped to successively flip the pawl out of tooth engagement as the wheel rotates in a forward direction on the messenger. The pawl is adapted to be released so as to permit free rolling of the trolley wheel in either direction by means of a cable 25 which is reciprocable in a flexible housing 26 attached to the head 8 as shown in 11. One end of the cable 25 is attached to a pin 21 projecting from the pawl 2| and the other end is connected by a clamp 28 with a ring 29, the ring being pivotally carried in a bracket 38 attached to the head 8 adjacent one side of the gap therein. When the tooth 25 of the pawl 2| is engaged with a tooth iii of the ratchet wheel i8, the cable 25 retains the ring in the forward position so that when the ring 29 is rocked in the opposite position by means of a rope or chain 3|, the pawl 2| is rocked to lift the tooth thereof out of engagement with the ratchet wheel l8 and thereby permit freedom of movement of the trolley wheel l5 in either direction. The flexible member 3| is of sufiicient length so that it may be manipulated from the ground when desired.

The trolley wheel has a resilient facing 32 to enhance friction thereof with the messenger and the facing is provided with an annular groove 33 to facilitate retention and guiding of the wheel thereon.

In order to guide the aerial cables into lashing position, the front head 8 carries

brackets

34 and 35 that are pivotally mounted on opposite sides of the passageway through the trolley on studs 36 and 3'1. The

brackets

34 and 35 depend from the studs 36 and 31 alongside of the gap in the head and have inwardly directed terminals 38 that are adapted to extend across the gap and mount the lower ends of

shafts

39 and 48 respectively. The other ends of the shafts are carried in bearing brackets 4| and 42 that are attached to the

brackets

34 and 35 near their pivotal mountingwhereby the shafts are positioned on upwardly and outwardly diverging axes to rotatably mount

elongated guide rollers

43 and 44. The

rollers

43 and 44 are thus supported in V form across the entrance end of the passageway 4 whereby the aerial cables ride within the V in bearing contact with the

rollers

43 and 44 as shown in Fig. 8. The position of the

guide rollers

43 and 44 thus brings the cables together in a substantially triangular form and in position so that the aerial cables A and B are adapted to closely engage the messenger with the aerial cable C tangentially contacting the aerial cables A and B.

In order to retain the guide rollers 43 land 44 in cable supporting position against action of coil springs 45, the plate 8 is provided with brackets 46 which pivotally mount latch levers 41 having ends 48 that are resiliently retained in engagement with the back sides of the

roller brackets

34 and 35 by coil springs 49 (Figs. 3 and 12). The opposite ends of the levers 41 project slightly beyond the periphery of the head 8 to provide handle portions 50 by which they may be rocked against action of the springs 49. As soon as the ends 48 of the levers pass below the

roller brackets

34 and 35, the springs 45 (Fig. 8) swing the roller brackets out of position across the gap in the head 8.

The levers 41 are mounted on cross pins 5| and the springs 49 are retained in position by sleeving them on arcuate guides 52 that are carrled by the levers 4'! and which move into openings 53 in the head 8 as the levers are rocked to release the

roller brackets

34 and 35. The springs 45 are connected to the flange extensions l3 and M and with arms 54 projecting upwardly from the roller supporting brackets.

Mounted on the outer face or the rear head 8 in substantial alignment with the sides of the gap therein and above the gap in the head are

parallel guides

55 and 56 having inwardly facing flanges 51 spaced from the head to provide guide grooves 58 slidably retaining oppositely disposed flanges 59 of a trolley wheel mounting bracket 60 which carries a freely rotatable trolley wheel 6| corresponding in construction with the trolley wheel |5 previously described for supporting that end of the trolley. Mounted on the flanges of the trolley wheel bracket are pivot pins 32 carrying depending levers 63 having a series of laterally disposed ratchet teeth 64 which are retained in engagement with ratchet teeth 65 on the overlying portions of the

guides

55 and 56. The levers 63 are normally retained in tooth engagement by coil springs 6-6 interposed between the free ends of the levers and sides of the wheel bracket. The teeth 64 and 55 are shaped so that the wheel bracket can be shifted toward the passageway 4 through the cylindrical body of the trolley but the teeth retain the bracket from movement in the opposite direction unless the levers are moved together to release the teeth thereon from the teeth of the guides. To facilitate movement of the levers, the free ends thereof are provided with pins 8'1 that are adapted to be gripped oy the fingers of the operator. The pins also facilitate movement of the wheel bracket to a retracted position. The trolley wheels are thus adapted for rolling support on the messenger to carry the machine therealong under pull of a cable 68 that is connected with a ring 69 which is attached to the forward head on the opposite side of the gap with respect to the rin 29 previously described.

The end of the trolley carried by the wheel BI is closed by an arcuate plate or gate H1 that is hinged at one side of the plate on a stud H to swing to and from closing relation with the gap. The gate is retained in closed position by a catch 12 that is pivoted on the end plate by a screw 13 and which is provided with a hook I4 adapted to engage a keeper 15 attached to the underside of the gate as shown in Fig. 10. The catch has an arm I6 extending from the opposite direction to release the catch. The catch is normally retained in latch position by a coil spring H having one end hooked to the arm and the other to a screw 18 on the guide 56. The inner periphery of the gate 18 corresponds in radius to the pasthe rollers. The opposite side edges of the plate are guided in groooves 89 and 9B of parallel guides ill and 92 that are mounted on the outer face of the gate 16 at the respective sides of the circular opening. The guides have overlapping flanges 93 provided with a series of ratchet teeth 94 that are engaged by ratchet teeth 95 on pawls 96 and ill. The pawls are pivotally mounted on the slide plate by means of pins 98 journalled in brackets 93 attached to the slide plate 81 and forming housings for enclosing the ratchet levers. The ratchet levers are moved into and out of contact with the ratchet teeth on the guides by levers I03 pivoted on the pins and Movement of the slide plate 81 is limited in the direction of the trolley roller by a lug I04 that extends from the guide 9I. The movement of the plate 81 is limited in the opposite direction by a lug I35 carried on the gate at a point directly 7 below the opening formed thereby.

With this construction, it is obvious that the aerial cables are kept in substantially triangular formation and in contact with the undersideof the supporting strand ormessenger, the position of the rollers being adjustable to conform with the diameter of the cables.

The machine also includes a spinning head I08 that is rotatably mounted abouttheaxis of the cylindrical body of the trolley. The. spinning head. includes a substantially cylindrical casing I01. The casing I31 has rounding endsterminating in inwardly extending end'flanges I08. and I09v encircling the endflanges of the cylindrical body of the trolley. The housing also has alongitudinal gap H3 in the circumferential wall thereof and the sides of the gap are, definedpby inwardly extending parallel flanges III: and; H2 spaced apart according to the spacing of thelongitudinal gap in the trolley.

Fixed to the outer side of the rear end flange is an angle H3 having one fiange; fixed; to the end flange of the housing by fastening devices such as screws H4. The other flangev extends outwardly toward the end plate 1 and forms a track H5 which is supported on a plurality-of circumferentially spaced rollers IIB. carried on the trolley, the rollers IIG being mounted on heads I I1 having eccentricallyv positioned shanks I.I8 that are carried by the end plate1. the shanks being rotatably adjustable in the end plate to permit adjustment of the rollers and thereby maintain the track in concentric: relation with the tubular body of the trolley. The track also has a gap I I9. The opposite end of the spinning housing has a similar track I20. fixed to the end flange I39 but which is of larger diameter for support by a series of circumferen tially arranged rollers I2! adjustably carriedon the end flange 8 in the same manner astherollers on the end flange i. The housing is, thus adapted for rotatable support about the axis of the trolley. Formed in diametrical opposite sides of the housing are reel recesses I22 and I23 car.- rying spindles I24 and I25respectively. Mounted on the spindles are reels I26 and I21 carrying the lashing wires E and F. The reels may beretained on the spindles by means of latches I28 and I29 that are carried by the spindles and latch over the hubs I39 of the reels. The; wires areguided from the reels by grooved guide pulleys; I that I are eccentrically. carried; on disks- I 1. The driving track is extended across the gap in the end plate by an arcuate segment I49 attached to the inner face of the gate 1%, the ends of the segment being provided with tongues I56 which engage in slots i5! and IE2 on opposite sides of the gap so as to take the end thrust when the friction rollers bear upon the gate. The friction rollers are maintained in contact with thedrive track by means of rollers I53 that are rotatably mounted on pins I54 carried in brackets I55 secured to the outer face of the end plate 6. The rollers are set so that the. peripheries thereof extend through slots I55 in the end plate and bear against the edge of the outwardly extending flange forming the track iii). In order to further supplement driving contact of the friction wheels I46 and H3?- against the tracks, the

studs. are mounted on slide plates I8! having guidesupport on the spinning head to move the wheels, against the track under pressure of springs I82.

The trolley wheel I5 at the front of the machine and related cable supporting rollers are covered by a housing I51 which is secured in position on the trolley by screws I58. The housing has anvend. opening I59 and gap I30 which registers with the passageway and gap through the; body of the trolley. The housing carries a messenger guide IGI which is adjustable with respect to the messenger by a screw I52 carried in the housing and which passages through a guide slot I63 in a tongue I64 of the guide. The tongue also carries a pin IE5 that is guided in a slot I66 of the housing I51 to cooperate with the screw- I62 in retaining'the guide in vertical position. The guide has a fork end I61 that straddles the messenger.

In order to facilitate carrying the lashing machine and application thereof to a messenger, the side of the spinning head housingopposite the gap therein is provided with an arcuate recess I68 thatis bridged by a longitudinally extending handle I69; The handle is of hollow formation and contains a bolt actuating lever I10 which pushes a bolt I1I that is reciprocable through an opening I12 in the flange I09 into a socket I13 carried by the head 8. The lever has a dependingportion I14thatis adapted to be engaged by the fingers when the handle is gripped so as to project the bolt I1I into engagement with the socket.v I13. The bolt IN is retained in contact withthe socket I13 by a rounded end I15 on the endof theboltengaging in a groove I16 of the lever. To, project the bolt Ill, the lever I'EEI has an-inclined cam portion I11 which bears against the bolt. I1I when the lever I10 is moved upon gripping ofv the handle. To release the bolt IN, the. lever I1Ilhas an upwardly projecting end I18', that is pushed downwardly by the thumb to disengage the rounded end I15 of the bolt In from the groove I15, the bolt being retained under action of a. spring I19 that is sleeved over the bolt and has one end bearing against the housingzgand its-opposite end bearing against a collar: I 80. on the. bolt.

In'rusinggthedevice;the reels of spinning wire are applied to the spindles I25 at the respective sides of the spinning head and the ends are extended under the guide pulleys I35 and then looped about the grooves of the pulleys I42 and I43. The machine is carried to the point of application by the handle 63 with the lever I'iIl in position so that the notch IlE thereof engages the rounded end Il of the bolt I'lI to hold the bolt in engagement with the socket I73. The spinning head is thus locked from rotation with respect to the trolley with the gap H9 thereof registering with the gap 9.

The handle portions 59 of the levers 4? are engaged to rock the levers against action of their springs 49. The springs 45 then swing the

roller carrying brackets

34 and 35 out of position to open the throat or gap 9 of that end of the machine. The gate '10 is then swung to open position as shown in Fig. by shifting the catch "2 to release the hook I4 thereof from engagement with the keeper E5. The gate then swings downwardly and outwardly away from the throat or gap 9 so that the entire machine may be then applied over the messenger and the aerial cables that are temporarily supported thereon, the trolley wheels I5 and SI being seated to roll along th .messenger as illustrated in Figs. 8 and 9.

The

roller carrying brackets

34 and 35 are then moved into position so that the rollers close the gap 9 at the forward end of the trolley and support the aerial cables as shown in dotted lines (Fig. 8). In this position, the latch levers 4! move into engagement with the roller brackets so as to lock the brackets in cable supporting position. The gate '10 is then closed and latched to carry the rollers '19 and 86 in position for supporting the aerial cables at the opposite ends of the machine. The trolley wheel GI and rollers 19 and 8E! are then adjusted to properly center the aerial cables and messenger with respect to the axis of rotation of the spinning head. These adjustments are effected by releasing the levers 63 from tooth engagement with the ratchet teeth 65 and sliding the trolley wheel bracket along the guides until the trolley wheel is in proper position, after which the levers 63 are released and the springs 65 return them into position so that the teeth thereon engage the teeth of the guides, to support the trolley wheel in adjusted position.

The

rollers

79 and 80 are adjusted by sliding the plate 8'! in the guides SI and 92. This is effected by releasing the teeth 95 on the pawls 9E and 9? from engagement with the teeth 94 on the guides 9I and 92. After the plate has been shifted to bring the rollers into desired position, the pawls are allowed to return into position so that the teeth thereof engage the teeth of the guides and which look the Plate from further movement. The free ends of the spinning wires are then attached in fixed relation to the messenger and aerial cables. A rope or other flexible connection 68 is connected with the ring 69 and a rope or flexible connection is made with the ring 29. The yoke I61 is adjusted with respect to the messenger by loosening the nut of the screw I62 and moving the yoke to desired position, after which the nut is re-engaged to retain the yoke in position. The spinning head is then released by tripping the lever I79. This is effected by applying pressure on the projecting end I18 and shifting it downwardy through the handle so that the spring I19 on the pawl III withdraws the bolt from engagement with the socket I13. The spinning head is then free to rotate about the axis of the trolley upon application of draft power to the flexible connection 68.

As the machine is drawn along the messenger, draft on the spinning wires and pay thereof from the storage reels causes the pulleys M2 to rotate about the axis of the studs I44. Rotation of the pulleys causes the friction wheels It! to roll along the track I48 and eifect rotation of the spinning head about the axis of the trolley. This movement of the trolley causes the spinning wires to be Wound spirally around the messenger and the aerial cables as shown in Fig. 1.-

Tension is kept upon the spinning wires in case of slacking oif of the draft power applied by the flexible connection 68 by the ratchet wheel I8 which is connected with the trolley wheel 15 so as to thereby prevent any retractive movement or back up of the machine. In case it is desired to release the tension, this is effected by pulling on the flexible connection 3|. This movement rocks the ring 29 and pulls on the cable 25 to lift the pawl 2| out of engagement with the ratchet wheel. Upon release of pulling force, the spring 24 returns the pawl in engagement with the ratchet wheel to prevent further back up of the machine.

With the machine in operation, it is obvious that two spirals are wound around the messenger and aerial cable and that the aerial cables are retained in tangential contact and in engagement with the messenger so that the spirals of lashing wires are drawn tightly therearound with the spirals formed by one wire in spaced relation with the spirals formed by the other wire.

The reels I30 include spaced disks H34 and I having rolled peripheries I86. The centers of the disks have openings IBI encircled by annular corrugations I88 to seat the ends of a sleeve I89. The sleeve I89 has tongues I9I that extend through slots I92 in the corrugations and are bent retractively over the outer faces of the disks to retain the assembly. The openings I81 are of a size to be freely passed over the spindles i2 5 and I25. The lashing wires have the inner ends suitably anchored to the sleeves as by extending the ends through openings in the sleeves and after being wound on the reels have their outer ends temporarily anchored in a slot I92 of the rolled rim of the outermost disks prior to application of the reels to the spindles. After application to the spindles the outer ends are disengaged and wrapped around the pulleys I42 and I43 respectively.

From the foregoing it is obvious that I have provided a cable lashing machine which is adapted to spin a plurality of lashing wires and which supports one or more aerial cables in the required position to be secured by the lashing wires.
