PIPE-WRAPPIN G MACHINE.
Application filed June 27, 1922. Serial No. 571,198.
To all whom it may concern:
Be it known that we, LELAND S. RosnNnn and FRANK I. DOANE, citizens of the United States of America, and residents, respec tively, of the city and county of San Francisco, and Berkeley, county of Alameda, State of California, have invented a new and useful Pipe-Wrapping Machine, of which the following is a specification.
Our invention relates to pipe wrapping devices. One of the objects of the invention is the provision of an improved pipe wrapping machine in which the pipe is rotate-d and fed forwardly thru the machine by the same feed rollers. Another object of the invention is the provision of a pipe wrapping machine in which the ratio between the s eed of rotation and the speed of longitudinal movement of the pipe may be readily adjusted to determine the pitch of the spiral characterizing the strip of covering as it is rolled upon the pipe.
Our invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of our invention. It is to be understood that we do not limit ourselves to the showing made by the said description, as we may adopt variant forms of the invention within the scope of the claims.
In the drawings, Fig. 1 is a front elevation of the machine, portions of the structure being broken away. tional view of a portion of the machine, the plane of section being indicated by the line 2-2 of Fig. 1. Fig. 3 is a plan view of the machine.
In terms of broad inclusion, our invention comprises a machine in which a pipe may be covered by a strip wound helically thereon. The end of the strip is applied at an angle to the pipe, and the pi rotated and at the same time fed forward y, so that the strip is drawn upon the pipe. The pipe is rotated and fed thru the machine by a plurality of feed rollers, which are mounted for pivotal movement about an axis perpendicular to their axis of rotation, and means are provided for moving the rollers on their res ective pivotal axes so as to adjust the ratio'between the speed of rotation and the speed of axial movement of the pipe. If the axis of rotation of the feed rollers is Fig. 2 is a sec-' parallel to the axis of the pipe, rotation of the feed rollers will effect merely a rotation of the pipe, but if the rollers are turned out of such parallelism, each in equal degree, the pipe is not only rotated but fed forwardly as well, and the ratio between these two movements, that is to say, the pitch of the spiral described by a given point on the surface of the pipe depends on the an ularity of the adjustment. If the feed rol ers are turned to an angle of 90 from the first position so that the rollers are turning in a plane coincident with the axis of the pipe. no rotary movement is given to the pipe, but only axial movement.
Means are also provided for simultaneously driving the feed rollers; for permitting radial adjustment toward and from the axis of the plpe to accommodate different sizes of pipe; for simultaneously adjusting the angularity of the feed rollers to the axis of the pipe; for feeding a strip of wrapping material to the pipe: and for impregnating the wrapping material with a waterproof composition. such as asphalt, immediately before the wrapping material reaches the pipe;
More particularly, our machine comprises a frame of which the chief parts are a pod estal 2, and preferably three radial extensions 3,. rojecting from a central barrel 4. In each rame portion 3, a hollow shaft 6 is mounted for pivotal movement about the axis 7, which extends radially from the axis 8, passing thru the center of the barrel 4 and coincident with the axis of rotation 9 of the pipe 10.
Mounted for axial movement in the hollow shaft 6, but not rotatable therein because of the key 11, is a hollow shaft 12 provided with threads 13 and carrying a hand wheel 14 threaded thereon. A coil s ring 16 is interposed between the hand whee and a bridge plate 17 The hand wheel bears on one side against a portion of the frame, and by turning the hand wheel the sleeve 12 may be moved radially onits axis 7, the spring 16 tending to keep the adjustment fixed but permitting limited outward movement. The lower portion of the sleeve is provided with a yoke 18 within which a shaft 19 is journaled. A knurled feed roller 21 is fixed on the shaft so that the axis of taneously rotation 22 of the feed roller intersects the axis 7, which also passes midway between the lateral faces of the roller. On the end of the shaft 19 is a beveled ear 23 in mesh with a similar ear 24 fixe on a shaft 26, which is journa ed in the sleeve 12 and extends upwardl therethru and thru the coil springs 16 an bridge plate 17, and thru a gear 27 splined on the. end thereof. The
Means are also provided for turning the shafts 6 simultaneously, to adjust the angularity of the feed rollers, that is to say, the angle which the axis 22 makes with the plane determined by the axis 7 and the axis 9. Fixed on each hollow shaft 6 is a segment of a gear 36 adapted to be meshed with a gear 37 mounted for rotation on the end of the barrel 4, opposite the mounting of the gear 31. The gear 37 is retained on the barrel by a collar 38 provided with brackets 39, in which the hand wheel controlled shaft 41 is journaled. The shaft 41 is provided with a worm 42 engaging worm teeth formed on the hub of the gear 37. Rotation of the shaft 41 by the hand wheel effects a turning of the gear 37 and a simultaneous movement of each of the hollow shafts 6 about their respective axes 7. Because of the irreversible character of the worm the shafts 6 are retained in their adjusted position without additional locking means.
From the above it will be clear that the feed rolls may be adjusted radially to engage a pipe of any desired size within the range 0 the machine and by then backing off the hand wheel a trifle, the rolls are resiliently held against the pipe by the springs 16 which give sufficiently to permit the rol s to accommodate themselves to any inequalities in the surface of the pipe. The angularity of the feed rolls is then adjusted in accordance with the width of the covering strip and the amount of the lap, if any, by the hand wheel 40. Rotation of the gear 31 effects a simultaneous rotation of the feed rollers and the rotation and axial progress thru the machine of the pipe.
Means are also provided for feeding a str'i of covering material impregnated with hot bituminous compound to the pipe. Arranged ad'acent the mechanisms ust described is e framework comprising a tank barrel 4, on which it is retained H 51 in which a quantity of material such as asphalt may be heated by any suitable source of heat in the fire-box 52 formed in the lower (portion of the frame. Elements 53 dispose on the frame are provided with means for mounting a roll 54 of the material to be wound on the pipe. This material 55 is led over a guide roller 57 downwardly into the body of hot asohalt over the roller 58 then upwardly past the scraping bars 59 which remove the surplus material clinging to the strip and over the aide roller 61, which is a justable vertical y on the slideways 62, by means of the screw 63. The strip then passes to the pipe at an angle determined by the pitch of the helix characterizing the wrapping as it is ap lied.
In Figs. 1 and 2 the feed rol ers are shown at such a setting that only rotation of the pipe would be effected, but under service conditions it is obvious that the rotational axis of the roller 61 must be in parallelism with the rotational axis of the rollers 21, since the angularity of the feed roller axis 22 determmes the pitch of the spiral winding, and the roller 61 must of course be perpendicular to the direction in which the winding strip is delivered. The first length of pipe is fed thru the feed rollers and the winding strip started by hand. As the end of the piece approaches the feed rollers, a suitable plug is inserted and another length of pipe attached. The operation of the machine is thus substantially continuous. The lengths of pi e are separated later as desired by cutting t ru the covering and removing the connecting plug.
The apparatus of our invention is particularly suitable for covering fabricated or cast pipes of varying diameters and may readily be adjusted to pipes of different sizes and to different conditions in the winding of the covering strip. A special factor of usefulness of our machine lies in the fact that it may be set up and operated at the point where the pipe is to be used.
