Application July 12,
1935, Serial N0. 30,958
Renewed June 2, 1936 7 Claims.
' 'l'.'his invention relates to a device for protecting threads on pipe ends and other such threaded articles when being handled and during transportation thereof.
The object of this invention is to provide a new and'improved means of protecting the threaded ends of pipe, in the nature of a substantial collar lhaving a yielding member coiled therein before being mounted on the end of the pipe.
Another object is'to provide a reinforced yielding thread engaging member.
To these and `other'means the invention resides in certain improvements in combination of parts, and is illustrated in the accompanying drawing wherein- Fig. 1 is an elevation of a pipe having a protector embodying my invention applied thereon, the protector and pipe end being shown in section.
Fig. 2 is an end elevation of the thread protector.
Fig. 3 is a sectional view of the means of fastening the ends of the resilient member to the substantial body.
Fig. 4 is a perspective view in part of the substantial body showing the tongue pierced and formed from the body.
Fig. 5 is a part sectional view of the protector and a pipe showing the protector in a locked position.
In the drawing I have shown the protector as applied to a pipe 1. The protector comprises a band 8 having an inturned flange 9 and arranged to overlie the end of said tubular articles. The opposite edge of the' band 3 is provided with a circumferential bead' I0 extending inwardly in relation to its diameter and its inner diameter being slightly greater in diameter than the outside diameter of the tubular article to be protected. Spirally coiled within the band 8 is a compressible yielding thread engaging 'member II. It is important that the thread engaging member be kept from rotating spirally within the band but not from moving slightly laterally therein and that it be held against the inner wall of the band 8. To accomplish this a reinforcing member I2 is provided within the thread engaging member I I, to hold the thread engaging member in position to prevent the accidental removal of the yielding member I I during the shipping or handling of the band previous to the installation thereof onto the pipe. ends I3 of the yielding member II from rotation around the band in assembled relation to the band 8 when the band is being applied to the pipe,V
In order to prevent thetongues I4 are lpierced and formed outwardly from the body of the'band providing openings I5 through which the ends I3 of the yielding member II are inserted. Then the tongues I4 are depressed to the position indicated in Fig. 3 to securely clamp the ends I3 against the body of the band 8.
The band with the yielding member therein may thus be placed on a pipe end by simply rotating it to position as shown in Fig. 1 whereby the inturned flange 9 abuts the end of the pipe. Then by the further rotation thereof the yielding member will be drawn against the tapered edge I'I of the bead I!) wedging the yielding member I I between the threads and the band 8 for retaining the protector on the pipe. This feature is plainly illustrated in Fig. 5.
I have shown a thread engaging member that can be saturated with oil or any nonrusting compound to prevent the threads from becoming rusted when subjected to a damp atmosphere and thus preserve the threads in good condition until the pipe reaches the place where used.
This invention consists in the construction, combination, and arrangement of the parts as described and shown in the accompanying drawing and is sought to be dened in the appending claims. It is to be understood, however, that the invention may be embodied in other ways, and that changes may be made therein without departing from the spirit of the invention and the scope of the claims.
Having thus described my invention, what I claim is:
1. A thread protector for covering the threads on the ends of tubular articles comprising an annular band having one edge thereof taperingly beaded inwardly, and a reinforced yielding member helically coiled within the body of the band and adapted when mounted on the threads to have engagement therewith to embed itself between the thread and to wipe the threads of foreign matter when the protector is being removed from the pipe.
2. A thread protector for covering the threads on the ends of tubular articles comprising an annular band having one edge taperingly beaded inwardly, a reinforced absorbent thread engaging member coiled within the body of the band, said absorbent member being means for retaining rust resistant compound and said reinforced member being adapted when mounted on the thread to have wedging engagement therewith to secure the band in position on the article.
.3. A thread protector for covering the threads on the ends of tubular articles comprisingan annular band having a circumferential inturned flange at one edge and a tapering bead at its other edge, a reinforced thread engaging member helically coiled therein between the said flange and the said bead and the ends of said thread engaging member securely anchored to said band, said thread engaging means being previously coiled therein and when mounted on said tubular articles to have wedging action with the threads to secure the band in position on th article.
4. A thread protector for covering the threads on the ends of tubular articles comprising arrannular band having a circumferential tapering bead on one edge, a reinforcedyieldingV thread f engaging element previously coiled against the inner surface of the band and adapted to-fbe ro v tated on the threads into wedging relation to said tapered bead causing said yielding member to be embedded in between the threads of the pipe for securing a protector on the object to be protected. v v i 5. A protector for the external threads of pipe comprising an annular band having one edge ilanged inwardly, the opposite edge being circumferentially taperedly beaded inwardly, a reinforced thread engaging member coiled within the body of the band between the said flange and the said bead, including means for securing the ends of the thread engaging member to the said band and when being assembled on the pipe the said thread engaging member being so arranged to be drawn vagainst the said tapered beaded edge for securing the protector to the article to be protected.
6. A protector for the external threads of pipe comprising an annular band having one edge inturned and arranged to contact with the end of the pipe, its opposite edge having a tapered bead extending radially inward, the inner diameter thereof being of slightly greater diameter than the external diameter of the threads, a reinforced fibrous thread engaging member spirally coiled against the inner wall of the said band and arranged to wedge the band on the pipe by the rotation thereof, said thread engaging means being previously coiled within the said band.
7 A protector for the external threads of pipe comprising an annular band having one edge inwardlyY bent to overlie and contact with the end of the pipe, its opposite edge having a tapered bead extending radially inward and the inner diameter thereof being of slightly greater diameter than the external diameter of the pipe, a reinforced fibrous thread engaging means helically coiled within the said band between the said flange and the said bead, the ends of said engaging means being secured to the said bands and the rotation of said bands in relation to the pipe will wedge the thread engaging means against the said bead and between the threads of the pipe anchoring the device on the pipe, the said thread engaging memberv being` coiled within the band before the said band is applied to the pipe. n
