MEANS T0 ATTACH A RING TO PIPE Filed May 16, 1955 Iva/mix MEANS TO ATTACH A RING T PIPE Ervin Beauregard Yeargan, Bakersfield, Calif. Application May 16, 1955, Serial No. 508,546

2 Claims. (Cl. 287--52.09)

This invention relates to a means whereby a ring or collar can be attached to the outside of pipe without rcquring the services of a welder or the like, as was the practice heretofore.

An object of my invention is to provide a novel means to attach a ring to pipe, whereby the ring can be quickly and easily mounted on the outside of pipe so that the ring will not move longitudinally of the pipe, and thus providing a stop in one instance for a tool which might otherwise slide along the pipe, or the ring may include a cleaning or scraping mechanism thereon for the purpose of scraping the inside of adjacent pipe.

Still another object of my invention is to provide a novel means to attach a ring to pipe whereby the ring can be positioned between the top and bottom collars of a pipe centralizer, said ring being easily attachable to the pipe after the centralizer is mounted thereon.

Still another object is to provide a novel means to attach a ring to pipe which is simple in construction, effective in operation and which will effectively hold the ring against longitudinal movement on the pipe after a setting mechanism has been released.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a side elevation of my ring attached to pipe and positioned between the collars of a pipe centralizer.

Figure 2 is a side elevation of my novel ring construction.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is a fragmentary longitudinal sectional view of a modified form of ring construction.

Figure 5 is a longitudinal sectional view of the ball retaining tube of the type utilized in Figure 4.

Figure 6 is a fragmentary side elevation with parts broken away and illustrating the use of my ring as a scraper.

Referring more particularly to the drawing, the numeral 1 indicates a pipe or tubing upon which my ring 2 is mounted. As shown in Figure 1 the ring 2 may be used as a stop in connection with a pipe centralizer 3 consisting of upper and lower collars 4-5, respectively, and bowed spring arms 6 mounted on and extending between the collars 4-5. The centralizer 3 is used for the purpose of holding the pipe 1 in the center of a bored hole, or within casing, and since the collars 4-5 are loosely mounted on the pipe 1 the centralizer could move longitudinally of the pipe as the pipe string is lowered into the Well. To prevent this longitudinal movement of the centralizer 3 it is necessary to use a ring such as my ring 2 as a stop, and the ring is positioned between the collars 4-5 and surrounding the pipe 1, substantially as shown in Figure l.

The ring 2 consists of two complementary arcuate sections 78 which, when attached together, encircle the pipe 1. The ring sections 78 are secured together at 7 2,812,200 Patented Nov. 5, 1957 diametrically opposite points by means of loose pins 9, which pins extend through a hinge-like structure formed on each of the sections 78, as shown. The pins 9 can be readily removed in order to permitthe sections 78 to be assembled on the pipe 1. The ring 2, as thus far described, is assembled on the pipe 1. How- 1 ever, a means must now be provided to prevent the ring from moving longitudinally on the pipe. This is accomplished as follows:

A pair of vertically extending channels 11-12 are formed on the section 8 of the ring 2. The channels 11-12 taper inwardly towards the upper and lower edges of the ring 2, respectively, and these channels are open on the inside and define a tapered enclosure with the outer surface of the pipe 1. Between the channels 11- 12 I provide a tube 13, which may be an integral part of the section 8 and of the channels 1112, or it may be a separate part, as will be subsequently described. A pair of balls 14-15 are positioned within the tube 13 and are pressed outwardly by the spring 16. The balls 14- 15 are held within the tube 13 by a key 17 which extends through appropriate holes in the tube 13, and above and below the balls 1415, respectively. In this position of the key 17 the spring 16 is compressed, the balls are held within the tube 13 and the ring 2 can be readily fitted onto the pipe 1. By withdrawing the key 17 the balls 14-15 are free to move upwardly and downwardly, respectively, and urged by the spring 16. The halls then move into the channels 11-12, respectively, and the tapered walls of these channels will guide the balls 1-4 15 against the outer surface of the pipe 1, thus wedging the balls against the outer surface of the pipe and against the tapered walls of the channels 1112. Thus the ring 2 will be securely attached to the pipe 1 and will be immovably held thereon. If desired the tube 13 can be a separate tube, as shown at 18, and this tube will contain the balls 14-15, as shown in Figure 5. The channels 1112 are then open at their inner ends providing an appropriate space 19 in which the tube 18 can fit. The key 17 releases the balls 1415 in the same manner as previously described, and the ring 2 will be mounted on the pipe 1 in the same manner as described above.

In Figure 6 I have shown the ring 2 constructed as a scratching or scraping tool, in which wire fingers 20 are fixedly mounted on the outer surface of the ring 2 and project therefrom, so that these fingers can scrape or scratch the inside surface of pipe for the purpose of cleaning the same. The ring 2 is held onto the actuating pipe in the same manner as previously described. It is thus evident that the detachable ring 2 can be used not only as a stop, but also as a cleaning tool, if desired.

Having described my invention, I claim:

1. A ring attachment to a pipe, said ring surrounding the pipe, the ring having a recess in the side thereof and a tube positioned in said recess, vertical channels in the ring extending upwardly and downwardly from said recess and from the tube therein, said channels being tapered towards the pipe and defining an inclosure with the outer surface of the pipe, said tube being open at both ends thereof, a pair of balls in said tube, spring means in the tube engaging both of the balls to press the bails outwardly and into each of said channels, and means releasably engaging the balls to retain the balls within the tube.

2. A ring attachment to a pipe, said ring surrounding the pipe, said ring having a recess in the side thereof and a tube removably positioned within the recess and adjacent the pipe, said tube being parallel to the pipe, vertical channels in the ring extending upwardly and downwardly from said recess and the tube therein, said channels being tapered towards the pipe and defining an inclosure with the outer surface of the pipe a pair of balls in said tube,

a spring within the tube engaging both of the balls to press said balls outwardly into said channels, and means extending through the. tube and enggxging the bglls tp retain the balls within the tube and-with the spring corn- 5 pressed. 7
