F R. LONG COUPLING NUT Fie July 30, 1936 Patented jan. 12, 1937 J naman STATES P-ATENT oFrcE mlzw N constructed as to become easily broken when subjected to a hammer blow in either driving the coupling nut home or releasing it to separate the union.
.Acordingly, a primary object of the present invention is tovprovide a coupling ring or socalled lug nut having a substantial body portion formed exteriorly with a plurality of angularly related faces for a portion of the depth thereof while the remainder of such depth is formed with radially projecting lugs of special formation. These lugs project sufficiently beyond the maximum diameter of the body to afford proper anvil faces andalso adequate leverage not only to convert a hammer blow or the like into rotary motion but also to distribute the force of the blow to opposite sides of the body to avoid breakage of they lugs. i
A further object of the invention is to provide a lug nut or coupling which may also function as a pipe hanger when used in connection with a support.
With the above and other objects in -view which will more readily appear as the nature of the invention is better understood, the' same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated and claimed.
A preferred and practical embodiment of the invention is shown in the accompanying drawing in whichz- Fig. 1 is a perspective view illustrating the application of the invention.
Fig. 2'is a side-elevation of the present improvement.
Fig. 3 is a top plan View of the invention installed for use, portions of the same being broken away to more completely illustrate the mode of In the embodiment of the invention shown in the accompanying drawing the same includes in its organization a body designated generally as- I, which is of annular formation having an internally threaded portion 2 for engaging with the 5 threads 3 of one portion of a pipe couplng and the interior annular shoulder 4 for engaging with a rib or shoulder on the mating part. of the coupling. i
The body is externally provided with a plural- 10 ity of tool engaging portions designated generally as A and B arranged in adjacent relation transversely of the axis of the body thereby to enable the body to be engaged by either a wrench or a hammer for imparting rotary or turning move-15 ment thereto.
The tool engaging portion A preferably comprises a plurality of fiat contiguous angularly related faces 5 which may in effect provide a hexagonal or other form of nut adapted for wrench 2 engagement. The said faces 5 are disposed in tangential relation to the annular face 6 of the body. Adjacent to the said angularly related faces 5 the body is provided with the tool engaging portion B, namely, the offset wings 1--1 which 25 are of substantially triangular formation with the apices 8 thereof extending outwardly beyond the body and considerably beyond the faces 5 as willbe apparent from the drawing. The side edges of the triangular extensions 'I-'l form anvil faces 9 which diverge inwardly from the apices fiitoward the body so that the anvil faces of opposite triangular members not only meet as indicated at IO but said faces lie substantially tangentially to the annular body' portion 6 previously referred to.
From the foregoing it will be apparent that the body of the nut or ring is provided for a portion of its depth along its axis with contiguous angularlyA related faces and for the remainder 40 of its depth is provided. with the triangular lug extensions. This arrangement makes it possible for 'a wrench to have free access to the tool engaging portion A without interference from the triangular lugs 1 and also makes it possible for ,45 a hammer (indicated in dotted lines in Fig, 1) to have adequate purchase on the anvil faces 9 of the triangular lugs without interference from the wrench engaging portion. Thus, when it is desired to tap the coupling home it will be apparent that the force of the hammer blow is distributed over substantially 180 degrees of the circumferenc'e of the annular or ring-like body thereby effectively to impart the full 'force of the blow to the coupling body without breaking the lug and at the same time ob e-.vethe full henefit of the hlow in completely seating the couplne. The triangular lugs 'i are therefore a distinctive 'feature of the invention. Moreover, their location with relation to the wreneheng'aging portion has the advantage of making itpossible to use a wrench and hammer simultaneously, if desired.
A further practical advantage of the lugs 'l is that they may provide a. pipe hanger asillustrated-in Figs. and 5. For example, suitable bracket means including the arms or pins ii-ii may be secured to a support and the lugs 'l-l may rest thereon In the example shown the arms or pins li'-li may be formed from a single U-shaped piece of metal. The supports may be placed at the'location of the lugs wherever the union happens to be located and will eflectively prevent retrozrade movement of the pipe line. The distinctive feature is that the coupllinn has outwardly extending means for. enge i fa sup--v aoerme I claim:-
