yThis invent-ionrelates to a thread p'rotec` f tor for internally threaded pipe ends, couplings, andthe like, and has for its y'objectthe provision of afsimply constructed inexpensive protector whichmaybe readily and securely attached tothe end of a pipe or coupling to prevent injuryto the thread thereof when it is being handled or is in transit. f
VAn embodiment of the invention is illustrated inthe accompanying Vdrawings of which Fig. lisa plank view of a disk out of which the protector is formed; Fig. 9.a vview similarto F ig. l showingthe protector in a l5 further stage of its manufact-ure; Fig. 3 Aa Y rperspective view of they complete protector;
- andfFig. 4 a centralAk cross sectional view of the protector and t-he end of a pipe coupling in which the protector is yarranged The protector provided according to this invention is formed from a metal disk having va diameter substantially equal to the outer diameter of a coupling with' which it' is vadapted rto be employed. v From the center -of the disk a plurality of tongues, preferably two, arek st-ruckvand bent downwardly at right angles to the plane of the disk, and A are'then preferably pressed to arcuate shapey conforming to that of the inner wall of a pipekor coupling. For securing the protector kin place, threads areformed on the outer faces of the tongues for engagingthe internal threads lof the coupling. f c,
Referring now to the drawing, the inventionis illustrated` in a simple form as comprising a metal Vdisk l, from the central porl tion of which a pairof tongues 2 and 3 are formed by. slitting the disk in the manner yindicated in Fig. l and then pressing the portionsbetween'the slots downwardly and outwardly to positions at right angles to the plane of the disk, and opposite to e-ach other. AIn r'addition to being forced downwardly, the .tongues are preferably pressed to arcuate lshape conforming to t-he inner walls ofa 7 coupling, and have threads 4 formed on their outer faces for screwing the protector into a coupling,vsu`ch as that illustrated at 5 in Fig. 4. c f The disk, as stated above, is preferably made with a diameter which is substantially the same as the outside diameter of a coupling to which it is adapted to be attached, or at least a diameter suh'icient to adequately protect the end of the coupling from being jammed kor injured when the protector is in place. To position the protector in the end of a coupling, tongues 2 and '3 are inserted in the end thereof and the protector rotated until disk l abuts against the outer end of the coupling, as illustrated in Fig. 4.
The simplicity and economy of construction, as well as the adequate protection afforded by the protector, will be readily appreciated by those skilled in the art. The protector may be made in various sizes, and may be used repeatedly. Although it covers only a portion of an internal thread of a pipe or coupling, nevertheless the protector so firmly grips the thread, and its peripheral margin so protects the end of a pipe or couplin'g that the thread as a whole is adequately protected l According to the provisions of the patent i statutes, I have explained the principle and 70 opeiation ofy my invention, and have illustrated and Adescribed what I now consider to represent its best embodiment. However, I
desire to have it understood that, within the 'scopeof the appended claims, the invention 80 may be practised otherwise than as specifically illustrated and described.
I Vclaim as myv invention:
l. A thread,fprotector for internally "threaded pipe couplings and the like, com- S5 prising a disk having a plurality of tongues bent downwardly from the plane thereof and provided with threads on their outer faces forengaging the internal threads of a pipe n or coupling, the disk having an annular mare annular marginal portion for protecting the p end of the pipe or coupling'.V Y
3. A thread protector Afor internally threaded pipe couplingsand the like, com#A prising a metal disk having arpair of tongues struck out of the Center thereof and bent downwardly at right angles thereto and op-v positegto each other, the outer, faces of said f tongues being provided with threads for enn gaging the threads of a pipe or coupling,V and thediskhaving an annular marginal portion for protecting the end ofva pipe or coupling. In testimony whereof, I sign my name."
