7 Claims.
Our invention relates to devices for wrapping pipe with a web of protective material such as felt, paper or the like. It is adapted particularly for wrapping pipe preparatory for laying said pipe in ditches, as in pipe line Work in oil fields; water or gas mains in cities, and similar situations.
To properly protect the pipe from rust and electrolytic action it is customary to coat the pipe with some corrosion-resisting compound such as asphalt and to then wrap the felt or paper spirally about the pipe and nally paint the pipe thus Wrapped with another coating. Machines have previously been devised for this purpose, but such machines are costly and are not conveniently transported over rough ground. It is an object of our invention to provide a light and easily portable device for Wrapping a web or Webs of protective material about the pipe.
It is also desired to provide a device Which is supported upon the pipe itself and is counterbalanced and easily rotated on the pipe to accomplish the Wrapping operation.
A further object of the invention is to provide a device which is adapted to apply one or more layers of Wrapping material to a pipe, each layer being applied in an overlapped manner with the webs of each succeeding layercovering the laps or joints of the lower layer. l
It is another object of the invention to provide a device with means thereon to support and center the device upon the pipe and in which the supporting means also acts to iron or smooth out the wrapping material in position upon the pipe.
We also aim to provide a Wrapping device which can be readily operated by hand by a single operator and automatically advanced along the pipe Without diiculty.
This application is a continuation in part of application Serial #426,820, led February 8, 1930, now Patent #1,883,401, October 18, 1932.
The construction of our device and the manner in which it is operated will be understood from the drawings herewith, in which:
Fig. 1 is an end elevation of our improved apparatus shown in operative position upon a section of pipe.
Fig. 2 is a side elevation of the apparatus yWith the parts in their operative position.
Fig. 3 is a side elevation of the device disclosing a plurality of rolls carried on the forward and rear parts of the device.
Fig, 4 is a detail view on line 4--4 of Fig. 2 in the direction of the arrows, disclosing the supporting arrangement for the counterbalancing Weights.
In the operation of protecting pipe by painting and wrapping it is a very difcult matter in the field to apply the Wrapping material uniformly upon pipe sections, and particularly upon pipe lines which have already been placed. Various types of machines and mechanisms have been devised to accomplish the painting and wrapping simultaneously or to perform the operations separately. These mechanisms, however, are more or less complicated, and we have therefore devised the present invention, which is very simple and economical in its construction and may be Yreadily transported from place to place and operated by one employe.
The device is best seen in side elevation in Fig. 1 and comprises a frame or support 2, which is made up of two or more circular sections 3 and 4. Each section comprises two spaced members 5 and 6, which are suitably connected by rods or spacing members 1. The sections 3 and 4 are hinged at 9 in any desired manner and on the opposite side are arranged for connection by a latch I0 which includes a bolt II and nut I2, `which may be adjusted on the bolt to clamp. the sections 3 and 4 iirmly in position. The bolt II is adapted for insertion in a slot I3 formed in a lug I5 which extends from the periphery of one of the sections. It should be noted that the frame is of considerably larger diameter than the pipe which is to be Wrapped and is arranged to encircle the pipe. By loosening the nut I2 and unlatching the bolt I I the frame may be passed about the pipe and the latch again secured.
The frame 2 is adapted to carry one or more rolls I'I of wrapping material. The supporting arrangements for the rolls are substantially the same. The roll in each supporting arangement is mounted upon a shaft I8, which is carried by an auxiliary frame I9, which is in turn supported by an adjustable connection 20, such as a ball and socket joint. The joint 20 is carried upon an arm 2I connected with one of the sections of the frame 2. The arm is extensible by means of slot arrangement 2|. In this manner, by adjustment of the connection 20, the roll I1 may be disposed at any desired angle as regards the pipe which is to be wrapped. One end of the frame I9 carries a guide roll 23 over which the wrapping material is adapted to pass. In devices of this type it is usual to wrap the material spirally about the pipe, and in Fig. 2 of the drawings the rolls of material are shown arranged at proper angles so that the material in each layer will overlap the desired amount in order to form a seal upon the pipe. As the frame 2 is rotated about the pipe 25, the Wrapping material will be wound on to the pipe, as shown in Fig. 2, in an overlapped relation, and in View of the forward advancement of the machine with the arms 2| adjusted to the proper lengths, the webs of the upper layer will cover the laps or joints of the lower layer.
In the modication of the invention disclosed in Fig. 3, rolls of wrapping material are also supported on the rear end of the frame in such a manner that upon rotation of the frame -the wrapping material is applied in an overlapped relation, with the webs in upper layers covering the laps or joints of lower layers, thereby enabling the operator to apply .one or a plurality of layers of wrapping material of like or different materials to a pipe at one operation.-
Thel coating operation is preferablyl performed by swabbing or ragging the paint or coating material upon the pipe ahead of the wrapping machine. This is usually performed by extending a canvas or similar wiper beneath the pipe, and the coating vmaterial is pouredupon the pipe and evenly distributed on the pipe with the wiper. Employees draw this rag about the pipe in a manner to coat the tar over its entire surface. Immediately vafter this ragging has been accomplished, the pipe wrapping machine is rotated so that the web of wrapping material is applied to the pipe.
It is desired to have the apparatus travel along the pipe at such a speed that the proper overlap of the spirals will occur. To accomplish this we have provided a plurality of supporting members 30. These members may take any desired form, but we have here illustrated them as comprising a plurality of stems 3l, which are non-circular and adapted for sliding movement through bearings 32. An adjustable nut 33 is threaded onto the lower end of each stern and arranged to conne a coil spring 34 between the bearing and the collar 35. This spring normally tends to move the stem 3! inwardly with respect to the frame.
A stop pin 36 is arranged for movement Within the slot 31 in the bearing so that the supporting member will not drop inwardly or outwardly when the apparatus is being transported or is not in use. Above the collar 35 the stem is formed with a yoke 40 which carries a pin 4l and a roller 42. This roller may be of any desired width, but we have herein illustrated it as of substantially the same width as the web of wrapping material. These rollers 42 may be made of any suitable material, but it is intended that they'may be made of rubber or some resilient substance which will smooth the wrapping material applied at the forward part of the machine. It will be seen from Fig. 1 that the spring 34 tends to force the roller 42 against the periphery of the pipe or the wrapping material which has been placed thereon. In order to suitably support the apparatus and to prevent vibration thereof, as well as to cause it to travel uniformly along the pipe, we have provided two sets of these rollers, the forward set 48, which are carried on the frame section 5, and a rear set 49, which are carried on the frame section 6. The bearing 32 is supported upon a suitable bracket 52, which is connected to the frame members by a bolt-..43. It is to be understood that this bracket 52 may be moved about on the bolt 43 in order to adjust the angularity of the roller with respect to the axis of the pipe. By adjustment of the angularity of?, this roll the pitch or rate of travel of the apparatus with respect to the pipe will be controlled. A set screw 44 ls shown as carried by the bracket 52 and adapted to engage against the frame section. Thus, if the bracket is once adjusted, the set screw may be arranged to retain it in the proper position. The bearing 32 is connected with the bracket 52 by means of bolts 46 which are arranged to pass through the slots 41 in the bracket. With this construction the rollers may be adjusted radially of the frame in order to accommodate different sizes of pipe or to allow for excessive movement of the rollers in passing dresser couplings or other obstructions upon the pipe. Where ordinary couplings are encountered, the resiliency of the stem 3l, due to its mounting with the spring 34, will allow sufficient movement of the rollers to pass the coupling.
With the rollers mounted as just described, it seems apparent that the wrapping material applied at the forward part of the machine will be pressed firmly and smoothly against the pipe. Referring to Fig; 3, it will be noted that auxiliary ironing rollers 60 are provided for pressing the wrapping material applied from the rear end of the machine to the pipe. These rollers, only one of which is shown, are mounted in yokes 6| adjustably connected by means of bolts 62 to spring arms 63 carried by the member 6 of the frame by bolts 64, the spring arms being extensible by means of slot 55 and clamping bolt arrangement 66. By means of the yoke and clamping bolt arrangement 62, the rollers can be readily placed at the same angularity as the supporting and ironing rollers 48 and 49, thereby eliminating any tendency to drag. These auxiliary pressing rolls may be eliminated whenever desired.
A restraining band or clamp 24 may be provided so that suitable tension may be placed upon the roll Il or the guid'e roll 23 in order to prevent the material from unrolling too freely. The forward set of guide rollers 48 tend to iron out or smooth the wrapping material immediately after it has been applied so that any wrinkles or bulges in the material will be removed and the material will slide about the pipe in order to remove them, due to the tension upon the web of the material. The rear rollers 49 are adapted to travel upon the material after several spirals have been applied to the pipe.- These rollers are so spaced from the forward rollers 48 that they will travel substantially upon the lap of the wrapping material and cause a sealing'of the joint along the spiral.
After the wrapping material has been applied withour improve-d mechanism, an outer coating of protective material or paint may be applied, if desired, either by a suitable painting mechanism or by ragging, as the rst coating was applied ahead of the wrapping apparatus. v
, The wrapping apparatus we have shown and described is primarily adapted for manual operation. The frame is passed about the pipe to be wrapped and it is thereafter rotated by the operator grasping the rods l and rotating the entire frame. rJzhe forward rollers 48 and rear rollers "0.9 will be adjusted with an angularity so that the apparatus will travel along the pipe at the proper rate, and the overlap of the wrapping material when once adjusted will thereafter be uniform.
For the purpose of balancing the machine so that it can be more readily operated, itv is provided with Weights 53 carried by arms 54, adjustably attached by clamping bolts 55 engaging in circumferential slots in the circular sections of the frame. Referring to Fig. 4, it will be noted that the weights are adjustably attached to the arms 54 by clamping bolts 56 engaging in slots 51. By means of the above adjustments, the operator is enabled to procure a very delicate balance of the machine so that it may be operated with a minimum of eort. Referring to Fig. 2 having diametrically disposed wrapping rolls, the weights may be dispensed with, as the rolls tend to balance each other. However, if only one roll of wrapping material is applied, with the other roll and supporting frame detached, there is a tendency to unbalance the frame, which requires increased eiort of operation. To overcome this, all the weights may be eliminated with the exception of one weight, which is diametrically disposed to the roll of wrapping material, and by means of the various adjustments disclosed, a normal adjustment forbalancing one roll full weight and when exhausted may be procured, so that the machine may be operated with a minimum of eiort.
Referring to Fig. 3, disclosing four wrapping rolls, all the weights may be eliminated, and it will be apparent that if the operator desires to apply these rolls, weights may be applied and adjusted at suitable places to maintain a normal balancing of the machine.
There will be no inconvenience in passing the roll of material about the pipe as is now encountered in hand operations. There will be no wrinkles or bulgesin""th"'rnaterial as it-will be ironed about the pipe by the rollers.
Our invention has the advantage of being economical to construct and easy to operate. One man can wrap the material upon the pipe where it takes four men to apply the liquidv coating thereto. The web of wrapping material is not only smoothly and evenly wound about the pipe but it is forced firmly against the pipe so that the coating previously applied makes a firm bond between the wrapping and the pipe. Also, by means of the plurality roll-supporting arrangement, a plurality of layers of wrapping material may be applied to effectively cover pipes to protect them under all conditions, the layers being applied in such manner that the webs of upper layers cover the lapping joints of lower layers.
While the device is particularly adapted for hand operation, it is to be understood that it is capable of power operation if so desired where mechanical devices are easily available.
