PIPE WRAPPING MACHINE 2 Sheets-Sheet 2 Filed May l0. 1950 INVENTORS Patented Feb. 28, 1933 UNITED STATES PATENT OFFICE" KELLIS H. BURTON AND HERMAN KRAMER, OF TULSA, OKLAHOMA, ASSIGNORS, BY MESNE ASSIGNMENTS, TO THE PHILIP CAREY MANUFACTURING COMPANY, A GOR- PORATION OF OHIO PIPE WRAPPING MACHINE Application filed Kay 10,

Our invention relates to wrapping -machines and more particularly to apparatus of that character for wrapping pipes and like cylindrical objects.

Before laying steel conduits in the ground, a coat of asphalt or like preservative is commonly applied to the outer surface of the pipe to prevent deterioration thereof. Due to the inherent drawing'qualities of the soil, the preservative tends to become disengaged from the pipe and adheres to the soil. In order to retain the coating of asphalt in intimate contact with the conduit, a layer of paper, preferably in the form of strips, is wound around the pipe. This operation has heretofore, been ordinarily accomplished in factories by rotating the pipe to wind paper thereon from a spool supported in stationary brackets. I

The principal object of this invention is to provide an apparatus for winding paper around a stationary pipe in the field, from a roll supported on a frame rotated around the pipe.

. A further object of our invention is to provide means for readily adjusting the amount of lap applied to the successive turns of covering material when wound spirally around a conduit.

Other objects of the invention are to provide means fOr'preVenting adhesion of the traction rollers tothe preservative coating, including means for a plying additional covering to the portion 0 the conduit requiring a heavy covering.

In accomplishing these and other objects.

of our invention we have provided improved details of structure the. preferred form of which is illustrated in the accompanying drawings, wherein:

device mounted on a conduit illustrated in cross-section. I

Referring more in detail to the drawings: 1 desi nates a pipeline preferably su ported ahove the ground in a position to e coated with a preservative and wrap ed with paper prior to being permanently la1d in the ground.

Mounted on the pipe or conduit is a pipewrapping machine 2 including spaced frame members 3 and 4, havin horizontal portions 5 and inclined legs 6, t e members 3 and 4 being preferably formed of angle bars com prising

flanges

7 and 8 directed outwardly and downwardly respectively.

Cross bars 9 and 10, fixed to the flanges 7 of the horizontal portions 5 by bolts 11, space the frame members and are provided with aligning bearing

portions

12 and 13 respectively for a purpose presently described.

Extended downwardly at right angles to the frame members and from the forward ends thereof are legs 14 and'15, also preferably constructed of angle bars, including inner flanges 16 fixed to the frame members by rivets. 17, and outwardly directed flan es 18 in alignment with the flanges 7 of t e frame members.

Rotatably supported between the lower I ends of the downwardly extending legs 14 the rollers in adjusted relation to the shaft,

the distance for spacing the rollers depend:

ing on the diameter of the conduit being wrapped.

In like manner a threaded axle 30, mounted f s between the inclined rear legs 6, in bearings 31, carries spaced rollers 32, identical in construction to the rollers 22 previously described. V

The frame and rollers above described provide a truck adapted to be longitudinally portions and moved on the pipeline and to rotatably sup port the wrapping mechanism 33, including a yoke frame 34, provided with an arch 35 extending upwardly between the longitudinal the frame member, and fixed tothe cross bar 9 and to the inner flange 8 by bolts 36.

Attaohdd' to the opposite faces of the yoke frameare duplicate yoke plates 37, having neck portions 38 formed complementary to the arch of the frame, and downwardly 4 extending

arcuate arms

39 and 40, spaced at of the yoke members over a conduit.

their lower ends by blocks 41 and 42 secured thereto by bolts 43. Lower portions 44 of the blocks are extended below the ends of the arms 39 and to mount spaced

bars

45 and 46, normally securedthereto by bolts 47, but detachable from the arm to permit mounting With the construction above descrlbed, a

substantially circular opening 48 is formed in the yoke member for receiving a rotatable carrier ring 49, including a relatively thin rim portion 50, adapted to be mounted in grooved rollers 51 interposed between the oke plates and between the spaced bars on Its 52 in an equally spaced, annular series surrounding the axis of the rotating ring.

A removable section 53, having slots 54' for receiving tongues 55 on the carrier ring, is provided for admitting the conduit into the carrier ring when mountin the wrapping machine on the conduit, olts 56 ex- ;tended through aligning openings in the tongues of the ring and rooved ends of the 2 may removed jointly therewith when mountlng the machine on a conduit.

Meshing with the ring gear 57 is an idler gear 61 rotatably mounted on a bolt 62, extended through a concentric openin 63 in the gear, through openings 64 in t e neck 50" port ons of the yoke plates, and through a s acmg collar 65 mounted between the plates.

enlarged portion 66 of the bolt forms a shoulder 67 for seating against the front yoke plate, and a nut 68- is threaded on the bolt to securely mount the idler gear inalignment with the ring gear.

J ournalled in the bearing

portions

12 and 13 of the plates 9 and 10 is a shaft 69, and

keyed to the shaft between said bearing portlons 1s a driving pinion 70 meshing with the;

idler gear 61. Secured to the forward end of the shaft 69, by a key 71, is a bevel gear 72 adapted to mesh with a bevel pinion 73 fixed to a transverse 'shaft 74, journalled in

bearings

75 and 76 secured to the outer ends of the frame members 3 and 4 by bolts 77. The shaft 74 may be rotated from either end by a crank 78 removably mounted on squared end portions 79 of the shaft.

- From the foregoing it will be apparent that l by rotating the crank, the ring gear is rotated at reduced speed around the conduit and this reduced rotary movement is utilized for winding a strip of covering material around the conduit from a spooling mechanism 80, supported on the ring gear by a bracket 81, having a shank 82 extended through an opening 83 in the gear and threaded on its outer end for receiving a nut 84.

mentary socket 86 of a spool head 87, on the inner end of a tubular shaft 88, rotatably supporting a roll of covering material or paper 89.

The supporting bracket is further provided with an arcuate slot 90 for receiving a curved arm 91, pivotally attached by a pin 92 between ears 93 integral with the head of the spool.

A series of openings 94 in the curved arm are adapted for selectively receiving a pm.

95 extended through aligning openings in the bracket member and through one of the openings in the curved arm, so that the spool of wrapping'material may be adjusted in angular relation to the ring gear to effect a greater or less amount of lap when winding material spirally around the conduit.

Means for applying tension to the roll of wrapping material to prevent unrestrained rotation thereof, includes a bar 96, having a head 97 on one end slidably movable on a shaft 98 integral with the head of the spool, a spring 99 being attached to the spool and to the head portion for normally urging the bar into engagement with the paper. The opposite end of the bar terminates in an inwardly depending flange 100, and attached thereto is a cord or the like 101 running over a pulley 102, mounted in the end of the tubular pulley shaft, the inner end of the cord Provided on.the rear end of the bracket is a ball portion 85 for seating in a complebeing attached to a spring 103 anchored said tubular portion.

In orderto simultaneously move the wrap; p'ng machine longitudinally on the conduit while rotating the carrier ring, a primary driving sprocket 104 is fixed on the shaft 74 in aligning relation with a sprocket 105, keyed to a shaft 106, journalled in bearings 107, secured to the facing flange 18 of the

angle members

14 and 15 by bolts 108, a chain belt 109 running over the

sprockets

104 and 105. Lateral movement of the shafts 74 and- 106 is prevented by collars 110 fixed to said shafts adjacent the inner faces of the bearings.

j A smaller sprocket 111, further secured to the shaft 106 adjacent the sprocket 105, is

connected by a chain belt 112 with a final tion rollers to the preservative on the conduit,

especially during warm weather, we have pro" vided means, nowto be described, for laying a track of paper or the like on the conduit ahead of the traction rollers, the track further serving as additional protection for the preservative when throwing dirt on the conduit to fill the ditch.

Secured to the lower ends of the facing flanges 18 of the

legs

14 and 15, by rivets or the like 114, are bracket members 115 having forwardly directed lateral ears 116 for pivotally receiving therebetween the arms 117 and 118 mounted on aligning bolts 119.

Rotatable on a shaft 120 extended through aligningopenings on the outer ends of the arms 117 and 118, is a spool 121 adapted to receive a roll of track-laymg material 122.

A pipe wrapping machine constructed as described is assembled on a conduit by removing the

bars

45 and 46 and the connected sections of the driving gear and carrier ring. With. the traction and trailer rollers supporting the machine on the conduit, the removable sections are again secured to the carrier ring and the

bars

45 and 46 are again attached to the yoke, the outer ends of the wra ping or track-laying rollers are secured to t e conduit and the crank is mounted on either end of the shaft 7 4 to suit the convenience of the operator.

Upon rotation of the crank, the machine is slowly drawn along the pipe by the traction rollers running over the track laid from the roll 122. Simultaneously the carrier ring is rotated through the train of driving, idler and driven sprockets, carrying therewith the roll of wrapping material.

If it is found, upon winding the conduit, that an insuflicient amount of lap is produced in the spiral windings, the pin 95 is inserted through the next upper opening 94 in the curved arm to effect a greater inclination of the wraping roll in relation to the carrier ring. To decrease the amount of lap, it will be obvious that a reverse movement of the roll is necessary. I

If the coating of preservative is sufficiently firm to prevent adherence of the traction rollers thereto, the track-laying apparatus may be readily detached from the machine by removing the bolts 119. 4
