DIRECT AND MESNE .essrennnnrs, re 'rHn PHILIP canny MANUFACTURING oom- IPANY, A CORPORATION OF OHIO 'rnue'x Arrnennnnrron EIPE'WB-APPING MACHINES Application filed September 8, 1930. Serial No. 480,508.

Our invention relates tofiwrapping ma chines and more particularly to conveying apparatus for.p1pe wrapping maclunes-of the character described in our co-pending application Serial Number d51,227

a The principal ;objeets ofourinvention are to provide means for stabilizing a wrapping machine during its longitudinal movement along a conduit, to provide means for facilitating the removal of a machine from a conduit, and to provide for transportation of the dismounted apparatus from one location to another. I

In accomplishing these and other objects of our invention wehave provided improved details of structure the preferred form of which .is illustrated in the accompanying drawings, wherein: v

Fig. l is a perspective view of a pipe-wrapping machine mounted on aconduit'andsupported,.partia lly, by a stabilizing wheel running on the ground.

Fig.2 is a perspective view of the machine dismounted from the conduit and supported on truck wheels for transportation.

Fig. 3 is a perspective viewxof an armor shaft used both for supporting the stabilizing wheel and for facilitating dismounting and transportation of the machine. a

Referring more indetail'to the drawings:

1 designates a conduit adapted to receive a pipe-wrapping machine, generally designated 2, including a frame 3 provided with rollers 4 for longitudinal movement of the apparatus on the conduit.

An extension 5 of the frame supports a motor 6 for driving traction wheels 7 of the machine through chains 8 and 9 operably connected by a countershaftt), through gears 10 and through a clutch 11.

Mounted on the forward end of the frame is a yoke member 12 for rotatably receiving a carrier ring 18 which is driven from the motor through a train of gears 14 and through aring gear 15 fixed to the carrier.

The carrier is provided with a removable section 16, and tie plates 17 extending across the ends of the yoke members, are detachably secured thereto to adapt the apparatus for convenient mounting or dismounting from a conduit.

A spool 18 for wrapping material 19 is supported from the carrier-ring so that retation of the carrier and simultaneous longitudinal movement of the machine will wrap material from the spool in spiral form around the conduit. 7

A wiping apron 20, further supported from the carrier on a rod 21,'is yieldingly anchored to the spool element by a hook 22 for urging the wrapping material into intimate engagement with the conduit.

The apparatus thus far described does not constitute a part of our present invention but is disclosed and referred to in connection with our invention to present a complete embodiment of the apparatus when equipped with the stabilizing and transportation means now to be described in detail.

The means for stabilizing the machine as t is moved longitudinally on the conduit includes a socket member 23, preferably comprising a relatively short end of pipe welded, as at 24, to the upper surface of the frame and in transverse relation to the conduit. This socket member is adapted to receive an arm or shaft 25 directed laterally from the machine andwhich is secured in the socket by a pin 26 removably extended through aligning openings 27 and 28 in the socket member and shaft respectively;

Threaded on the outer end of the shaft 25 is a head or T fitting 29, positioned in vertical relation'to the apparatus and a tubular stem 30 adapted to extend through'said fitting is welded or otherwise secured at its lower end to a fork 31 for rotatably mounting a stabilizing wheel 32 therebetween on a transverse shaft or axle 38; cotter pins 34 or the like extended through the axle adjacentits ends serving to retain the wheel in the fork.

The stem 80 is further provided with a series of transverse apertures 35 and across pin 36 is selectively extended througheither of said apertures to support the machine through the shaft 25 and T fitting, thereby preventing rocking of the wrapping machine by blots 40 and having downwardly inclined portions l1 twisted at right angles to the remainder of the arms and provided near their 7 outer ends with aligning openings 42 for receiving a shaft or axle l3 adapted to rotatably carry the wheel 37.

At angular bracket 44: is fixed to the yoke 12 preferably by bolts 45, and a pair of arms 46, having openings l7 adjacent their lower ends aligning with an opening 48 in the an-' gular bracket, are secured by bolts 49 to a vertical standard 50 of the frame.

A transverse shaft or axle 51 is extended through aligning openings in the angular bracket lfand pair of arms 46, and through the hub of the wheel 38. Cotter pins 52 and washers 58, as shown in Fig. 2, may

be used for retainingthe'shafts in the re- With a wrapping machine mounted on a" conduit in operable position as shown in Fig. 1 the shaft 25 is anchored in the socket member 23 by the pin 26, and together with the stem inserted through the T fitting 29 transmits a portion of the weight of the .machine to the stabilizing wheel, thus preventing excessive swaying of the machine on the conduit. 7

When a string of pipe has been wrapped and it is desired to transport the machine to another pipe string, the section 16 of the carrier ring and the plates 17 are removed to permit dismounting of the machine from the conduit. By then removing the pin 26 the stabilizing assembly including the shaft 25 are detached from the apparatus and disassembled. The shaft 25 is next inserted in the socket member 54 for rotating the frame on the conduit to engage the truck wheels 37 and 38 with the ground as shown in Fig. 2. As soon as the weight of the machine rests on the truck wheels the apparatus may be readily removed from the conduit-and transported for further pipe wr'apping operations. If desired, a handle bar 56 may be inserted through the T fitting 29 to facilitate these operations.

What we claim and desire to secure by LettersPatent is:

1. In combination with a pipe wrapping machineincluding a frame, brackets extending laterally from the frame, means for securing the brackets to the frame, wheels rotatably mounted on said brackets, and means on the machine for rotating the frame on the pipe to engage said wheels with the ground, and for effecting transportation of the machine.

2. In combination with a pipe wrapping machine including a frame, brackets extending laterally from the frame, means for securing the brackets to the frame, wheels rotatably'mounted on said brackets, a socket member secured in angular relation to the frame, and a shaft adapted for seating in said socket member to rotate the machine on the pipe for engaging said wheels with theground and for eflecting transportation of the machine.

"3. In combination with a pipe wrapping machine including a frame, a bracket extending laterally from the frame, means for securing the bracket to the frame, a wheel rotatably carried by the bracket, and means permitting rotation of the frame of the pipe wrapping machine while on the pipe so as to bring said wheel into position for transporting the machine away from the pipe in adirection at an angle to the longitudinal lay of the pipe.

4. In combination with a pipe-wrapping. machine including a frame, pairs of brackets extending laterally from the frame, means for securing the brackets to the frame, a wheel rotatably mounted between each pair of brackets, and means on the machine for rotating the frame on the pipe to engage said wheels with the ground for transporting the machine. In testimony whereof we afiix our signatures.
