14 Claims. l

This invention relates to the installation of aerial cable and more particularly to a machine for securing an aerial cable to a messenger or supporting strand. f.

One object of the present invention is to provide a machine for securing an aerial cable to a supporting strand in such a manner that the tension on the towing line secured to the front end of the machine forces the supporting strand into intimate engagement with the driving'wheels in the forward part of the machine housing.

Another object of the invention is the provision of a cable lashing machine which maintains the supporting strand and the cable in close relation and at the same time serving a lashing wire therearound to secure the cable and supporting strand together.

A further object ci the invention is the provision, in a cable lashing machine, of means for preventing the backward movement of the machine when forward tension on the machine isv released.

A still further object of the invention is the provision of a positive action driving mechanism for operating the rotating drum which carries the coils of lashing wire.

The machine of my invention is an improvement over the cable lashing machines shown in Patents 2,231,962, 2,272,253 and 2,544,313.

In the preferred form of my cable lashing machine, I provide a chassis having spaced apart stationary ront and rear portions and a rotatable cylinder or drum positioned therebetween and rotatable on the chassis. The forward part of the machine, that is, the stationary part, houses the driving mechanism for the drum and supports the front end of the machine. The rear end of the machine is provi-ded with means for supporting the rear end and provides means for holding the cable to be secured to the supporting in juxtaposition as it is lashed to the supporting strand. rihe rotating drum is provided with suitable compartments which are diametrically opposed and carry preformed coils of lashing wire. The wire from either reel is l out and wrapped around the supporting strand and cable as the machine advances along the supporting strand and secures the strand and cable togetherin sucha manner thatthere is little or no movement therebetween after the installation is, completed. 'Y v Y Means are located in the forward part of the machine associated with the driving means for preventing the lashing wire from slacking on. due to the lashing machine moving backward when forward ,tension on'the machine isreleased,

Means have also been provided in the forward part `of, the. machine and associated with the driving mechanism wherein the tension on the towing line controls the pressure of the driving wheelson the supporting strand by means associated therewith which forces the strand up into intimate contactwijth the driving wheels.

In the machine of my invention I have incorporated at the rear end thereof van improved means for supporting and positioning the cable and supporting strand just prior to the lashing wire being applied therearound. y

y The invention and the several features thereof will be more clearly understood from the following detailed description with reference to the acoompanying drawings in which: Y y

As shown in the drawings, the cable lashing machine of this invention comprises a chassis or frame I il having a longitudinally extending passage il therethrough. The front end i2 of the chassis it has mounted thereon an extended frame portion i3, on which there is mounted the driving mechanism for a rotatable drum 11i which is mounted on the chassis IG toward the rear of the frame i3. The drum is, is adapted to be rotated when the machine is t wed along the strand i5 by means oi the hand line l which is secured to the cable guide plate Il by the attachment i8. Y

As shown in Figs. 1, 2, 3 and 6, the front end housing I2 has mounted thereon an extending frame portion i3 which with the chassis lil forms the stationary part of the machine and contains the driving mechanism for the drum i4.

As shown in Figs. 2, 3, 5, 3, 15 and 16, the driving mechanism comprises a pair of V groove driving pulleys l and 2li, preferably made from a tough resilient material such as tire tread rubber. The pulleys is and 2i? are mounted axially on the shafts 2i and 22 which are journalled in suitable bearings 23, .25, 25. and 2S in the wall sections 21 and 28 of the housing. As shown, the wall sections 2 and 28 are spaced apart to form aeentral compartment 29 for the pulleys i9 and 2% and to provide on each side thereof the compartments 30 and 3l.

Located in compartment 33 and mounted on the end of the pulley shaft 22, is the gear 32 which is in constant mesh with the idler gear 33 mounted on the shaft Si which is journalled in the bearing in the wall section 2l and the web member 35. Also in constant mesh with the idler gear 3S is the gear 3l which is mounted on the end of the pulley shaft 2i which has mounted on each end thereof the bevelled gears 3S and 38 which are in constant mesh with the bevel pinions lil and il! which are mounted on the shafts i2 and L33. The bevel pinion 46, which is mounted on the shaft 2, is located in compartment one end of the shaft being journalled in the bearing 44 in the web 36 and the other end journalled in the bearing l5 in the frame il). In a similar manner the bevel pinion 4 El is mounted on the shaft i3 in the compartment 3|, one end of which is journalled in the bearing Lit of the web ill' and the other journalled in the bearing 48 of the frame lil.

Located on each end of the shafts l2 and t3, which extend into the housing i2, are the pinion gears 49 and E3; these gears are in mesh with the segmental ring gear 5I which is secured to the drum IQ by bolts 52 and is provided with a radial slot 53 which is of substantially the same Width as the passageway H in the drum meinber lil and the opening 5d in the chassis It and housing i2, as shown in Figs. 17 and 18. These openings are provided to permit the machine of this invention to be placed astride the strand i5 and the cable CA as shown in the various figures.

As shown in Figs. 3, 6, 17 and 18 and in more detail in Figs. 17 and 18, there is secured on the front face 55 of the drum i4, adjacent the outer periphery thereof, by bolts 55, a segmental ange or track member l. This, like the ring gear 5l and the face 55, has a. portion cut away to provide an opening therein which is in alignment with the opening all of the drum 513 and the passageway l l in the chassis I0.

Mounted in the housing l2, in circumferential relation with respect to the ring gear 5i, and rotatably supported on the walls thereof by suitable axles 58 are the guide rollers 59. These guide rollers are in engagement with the track member and serve as the front end bearing for the drum ill.

The rear end of the drum it, as shown in Figs. 6 and 2Q, is rotatably supported in the rear end housing et' of the chassis of frame lil, by suitable rollers axially mounted on the wall of the housing. As shown in Fig. 2S, two sets of rollers are provided; one set 5i is mounted in axial relation with respect to the drum iii on suitable supports 62 and in contact with the segmental track 53. Another set of rollers 54 is mounted radially on the supports with the' axes at right angles with respect to the axes of rollers 52 and serve as an end or thrust .bearing for the drum I by engagement with the outer end thereof. Thus, we have the drum it rotatably mounted on the rollers iii and the rear end housing Se and on the rollers 59 in the iront end housing i2 and rotatably driven by the power transmitted by the friction-al engagement of the V pulleys le and 2Q with the strand l5, thus driving the gears 32 and 3l and the idler gear 33, which in turn transmits pcf-.ver to the bevelled gears 38 and 39 which drive lthe p-inions f il and Il! and through the shafts l2 and e3, drive the pinions @il and 5d which are in engagement with the ring gear 5l mounted on the drum l Il.

The pinion gears i9 and 53 are so located with 'respect to the slot 53 in the ring gear 5| that the power transmitted to the drum if! through the ring gear and its associated gears, is constant, as long as the V pulleys it and 2i? are in engagement with the strand and the machine is being towed therealong, since at no time is the ring gear 5I out of engagement with one or the other of the vpinion gears i9 and 59.

-As shown in Figs. l, 2, 5, 8, 15 and 16 and more in detail in Figs. 8, l5 and i6, means are provided for forcing the strand l5 up into intimate engagement with the V pulleys i9 and 2D. The lmeans as shown comprises a vertical shaft E6 rotatably mounted in the guide bracket 67, which is secured in a recess in the wall 28 of the casting, which forms the 'compartment 29, as shown in Fig. '21, by the screws 68. The lower end of the ,shaft 5t," as Showni'tbevfiisfflgiiresfy; nel. particularly infligs'and l15p-is provided with an arm V59 vwhich''extends at rightanglesfwith respect to the shaft Stand has rotatably Imounted thereon 'a roller,member lil which is adapted to engage the strand E5; as shown` Iinthe various figures and .with particular reference .to Figs.l y6 and V15, and force the stiand'lll' up into intimate engagement with'thestrand whenthe shaft'it and its associatedv parts are moved upwardly. In itsnormalposition, as shownin thedotted lines inFlg. 2, the roller 79 of the arm 63 bears' against `but doesjnot exert pressure against lthe strand. LSince it is Vd'esirable that .thejrstrand'fl 5 bei forced upwardly [into Yintiniate engagement withthelpulleys 'I3 and Zton/lywhen :the mae ,chine :is in ,operationnieans have been proyided Acontrolled .'by the v`lforiifarti' tensionon"'the' tow line i6 which applies pressure on the roller Vlll and the consequent forcing upwardly of the strandw I5 linto intimate engagement withrthe pulleys I9 and 2li to provide the necessary tractionY to drive the mechanism which wraps the wire WR around the strand l5 and the cable CA, as shown in Fig. 1.

As shown in the various gures, the means for forcing the roller l@ upwardly into intimate ensagement with the pulleys i9 and 2c, comp-rises a-.braoket member .l which is secured to'the outer face ofthe guide plate i? by means of suit-- able rivets i2. The member i extends upwardly and has its extended portion in engagement with the shoulder 'i3 on the'member it which is pivotally supported on the frame it by means of the bracketvlE and the pin '55. A

. The free end il ofv the member 'M has a tapered conguration andfis bent Vat substantially right angles .to provide, the extending arm i8 which is adapted to 4engage the underside of theroller supporting arm V(iii when the member 5M is forced upwardly Vby the bracket ltwhen a force,,in the direction indicated bythe arrow in lFig` 18,k is applied to the guide plate il by the tow line i6 and its associated attachment i8.

In order to maintain Ythe roller l'iin engagement with the strand l and in such a manner that the :torce applied is knot sufficient to cause the strand l5 to be intimately engaged with the pulleys lil and 2l), a coil spring loris positioned between the. frame iii -and aprotuberanceonthe member lt. This spring, sinceY ,itv is .conned between the frame l@ and the member ld, forces the-member ill outwardly which,in turn; causes the extending arm portion lll to engage the roller supporting arm SS and maintain it in juxtaposition. Y l Y 'When the Ylashing machine is Ato be. placed on or removed from the supporting strand i5, the

armt9 .and its associated 4roller lll, as shown by n,

2, 5 and 8, and more in detailV in'jlig. 4 16,` there is pivctally mounted on the 'outer side of the bracket 811, by means of the' screw .lill,.and,lever arm H32, the upper end lllsof the arm 02 is bent substantially at right angles'andis in' engagement withA the underaccessi 7: side of the onset arm |04 which extends up.- wardly.V and is pivotallysupported byv the screw |05, as shown in Figs. 2 and 5. The upper end |05 ofthe arm Hlfis in engagement with, a pin |01-y on the arm |08 which is also pivoted on thgscrew |05.V

The upper or free end of the. arm |08 is provided with an aperture through which one end of the coil. spring |09 passes, the other end being secured to the pin H located on the frame casting of. the machine, thus biasing the arm |03.in the direction of the arm |04, and holding thepin |01l on the arm |08, in engagement with the end. of the offset arm |09.

Located on. thearm |08, as shown inFig..15:, is an extending tooth member which is adapted to engage the teeth |12 on` thev ratchet wheelV |13, whichis secured to the. shaft 2| thus providing a ratchetv device for the driving mechanism.

In its, normal or operative position. as shown in the various figures, the tooth on the arm |08, will be in engagement with the teeth ||2 on thewheel. |13, and due to the spring |09 will be held in contact therewith and prevent counterclockwise movement of the drive pulleys I9 and 20 and the subsequent riding backward on the strand of the lashing machine, with. the consequent releasing of the back tension on. the lashing wire, WR.V

Whenthe roller. and guide. plate assembly is opened,asshown injjig. 1l, 1c repar.atoryv to placing, the.. machine on or removing it from the strand and cable, the,l pin 86.0n the yoke 85 will engage the.Y bottom portion of the. arm |02 and Will f.0rce,it inwardly a slight distance andsince the. opposite end. of,` the arm |02 isin engagement. with thev lower end portion of the offset a1m |04. it will cause this arm to pivot on the screw |05, bear againstv the pin |'|.0 and move the armV |95 inwardly, thus, disengaging the tooth f,romv the.. teeth |,|.2 on.the ratchet wheel ||3, therebyv permitting thedriving pulleys or wheels `I l' and. 20 to rotate either in a clockwise .or

counter-clockwise direction. This structure pro,- vides a positive automatic means for preventing the machinel fromslidingbackward on the strand with the consequent loosening of the lashing wire, when forward tension on the tow line isreleased,

but permits the driving mechanism to rotate freely when the roller and guide plateassembly is opened during placement or removal of the machine on the strand.

A Sshowmin, Eigs, 6,A '7,y 17 and 18 and; more particularly, in Fig. 20,l aA guide pulley. |14, in alignmentA with the V-pulleys I9. and 2|), is locatedonthe interiory of the rear housingr 60 for supporting theV machine on the strand |5'..

Located on` the, rear end housing |50` of the chassis I0.,- which contains the rollers, f or supporting. the rear endofl the drumL |,4, is, means for forcing the-cable CA upwardlyv into engagement with the strand l5 and maintains, it in juxtapositionwhile thelashing wire WRisbeing. served therearoundasshown in Fig. 1. As shown particularly in, Fig. 4, cable positioning guidesare mounted on the face; |15. of, the rear housing: 69. and are adjustableto accommodate various sizes of cable. Secured to the.face.||5 of thevr rear housing 60, above the passageway screwsA |.B and. H1, are the bracketmembers H5 and ||9. These, brackets are spaced apart and areprovidedwith extending ear portions and |2|7 which have journalled therein the ends ofr aI horizontally extending.r threaded. shaft., |22

It will'l thus be observed. that upon rotation of the knob |23', either clockwise or counter-clockwise, the shaft |22 will be caused to rotate and since the members |25. and |21 and their associated members |32 and |33 with the rollers mounted thereon are operatively connected to the members |26 and |21, the rollers |38 and |39 will travel either toward or away from each other, thereby reducing or enlarging the space between the rollers |38 and |39, and since the connection between. the two sets of Lshaped members is exible,y to a degree, the rollers will conform to any irregularities of the cable sheath. while still confining. the cable therebetween and preventing undue sideward movement.

Associated with the rear cable guiding means heretofore described, and positioned adiacent to it, is a means for lifting. the cable CA into close proximity with the strand l5 just prior to the application of the lashing wire WR. The cable lifting means as shown in the various gures and with particular reference to Figs. 4, 612 and 13, is mounted on the face ii 5 of the rear housing 00 by means ofsuitable brackets |413 and |55, which are secured on each side of the passageway I| below the brackets I i8 and 9, which support the guide rollers |30 and |39by means of vscrews |55 andy |41'.

The brackets |44 and |45, as shown, are provided with spaced apart outwardly extending ears or lugs MiB-44S, and it-|09, in which the ends, of the vertically extending threaded shafts |50.and |5| are mounted.. The threaded shaft |5| is journalled in the ears Mil-|99, and is adaptedltobe rotated either clockwise or counterclockwise by means of the knurled knob |52 located on the upper end of the shaft |5|, and the shaft |50, which is flat onits rear side, is xedly secured in the ears Mii- |48 by pins (not shown). Hingedly. positioned on the shaft |5|, between the earsv |49j-|49, and in` threaded engagement vwith the shaft is the internally threaded boss member |53, whichVA is provided withl a downwardly` extending ear portion |54 in which there isI secured the outboard shaft |55, which extends across the passageway and has mounted thereon a. roller |55. As shown, the free end of the shaft 55 has secured thereto by means of the pin |57, a bifurcated sleeve member |58 having spaced apart extending arm portions i 59 and |60. The member |58 has pivotally mounted in its bifurcated end portion, between the arms |58 and |59, by means of the spring |6i, a spring biased latch or dogt |52, the end portion of which is notched at its and is arranged to engage the iiattened rear side of the shaft |50 as shown in Fig. 12 and lock the roller assembly closed. with the internally threaded portion of the bifurcated end of the sleeve |58 in engagement with the threads on the shaft |59.

When it is desired to either raise or lower the roller |56, to accommodate cables'of different sizes the latch member |62 is depressed, which causes the notched end |63 to become disengaged from the flattened rear portion of the shaft |56 thereby permitting the assembly to rotate on.' the shaft and swing open, as shown in Fig. 13. After the assembly has assumed the position as shown in Fig. 13, it may be raisedor lowered by the manipulation of the knob 52, thus when the assembly has been adjusted it may be returned to its normal or operative position and locked in place by the latch mechanism as heretofore explained. A

The drum ifi, as shown in various iigures, and with particular reference to Fig. 7, is provided with diametrically opposed compartments |64 and |65 in which there is conined by means of the gates It and |67 the coils of lashing wire |68 and |63. The gates |56 and |67 are hingeably mounted on the ears il! and 72 by suitable pins |73 and llt on each side of the passageway mounted across the top compartment CP is the cross member i7@ which provides a suitable handie for Uripping the machine to place it in position on the strand it. Locking means comprising the spring biased hinged bolts |75 and |76 and threaded wing nuts |77 and |73 securely hold the gates |56 and |67 in their closed position and conne the coils of lashing wire |63 and |59 between the protuberances |79 and me on the gates and the inner walls of the compartments |66 and |65. Journalled in the gates |556 and i557 are guide rollers |87 and |32. These rollers are located in suitable slots and are positioned over the protuberances |73 and |89 each of which are provided with circularly disposed apertures |83 and |84.

1n order to facilitate the feeding of the lashing wire WR from the coils |68 and |69 and to reduce the friction as much as possible, the axes of the rollers i8! and H32 are disposed at an angle and are in alignment with suitable guide rollers |85 and it which are rotatably mounted in the rear of the drum adjacent the end thereof. As shown the lashing wire WR, after leaving the coil |50, passes through the aperture |34, over the roller i8! one turn around the roller |85 over the roller |36 and thence around the strand I5 and the cable CA, as shown in Fig. ll.

A suitable cover |37 is provided on the forward end of the machine, over the driving mechanism and is held in position by means of suitable bolts 98, as shown in Fig. 9. y

In the application of the lashing machine of this invention to the practice of securing aerial cable to a supporting strand by means of a wire lashed therearound, in place of the usual cable rings, the following sequence of operation is V in their respective compartments |4 and |55.

l@ One coil, that is, the reserve coil |69 is left ine tact after it has been placed in position but the wire in the coil |53 is threaded through the aperture |83 over the pulleys or rollers |8l, |65, and |86, and is pulled outwardly a sufficient amount to provide an adequate length of wire for securing it to the cable CA and the strand it, prior to the operation ofthe lashing machine. liter the coils of lashing wire |67 and it have been positioned in the compartments and |55 in the drum id, as heretofore described, the strand tensioning roller 7G, mounted on the bracket 7| swung open from its normal or operating position across the passageway il. rl'he next step is to swing the rear cable supporting roller gigiitwout of its position across the passageway ii and adjust the vertical rollers |33 and its to the proper sizeof cable. The machine is then placed over the strand and cable with the strand I5 positioned in the grooves of the gpulleyrssldand limand in the groove ofthe rear pulley or roller li.
