Referring to the drawings in detail this improved lclip designated generally IIJ comprises 'aA body I2 formed of sheet metal Ywhich is of sube stantially concavo-c'onvex throughout its entire length as will? be `readily understood upon refer` enc'e to lFigures '3l' 4" and 5. Extending outwardly fromth'e convex side of thebody I2 andextendingV longitudinally 'substantially throughout the entireV lengt-h thereof is 'a reinforcing rib I4 which in 'the preferred form 'of'the invention is hollow to form a groove le'which opens into the con'- cave Side of the body as will be readily understood upon reference to the drawings. f
One end of the body is bent in a direction-'away from the'rib I4f`to .forme a hook I8, and formed integrally with the 'opposite end' of the bodyis a leg- Zllwhich extends substantially perpendicular to lthep'o'rtion: of: the'fbody adjacent said 'leg and cooperates; with vthe hook IB in vdeiining a recess 24".;forK the; -receptionwofvan insulated cable C or the As illustrated in the drawings, the 'rib 1'4" like.
Y not only extends around with the hook '|283 but also continues alongV the leg 2li, and`form'ed in the alongtheleg 2'0'and"the portion of the body which lies: adjacent the leg 2li-with `an 'opening-24' which alignsfaXially-wth the portion ofthe rib that liesalong-'the leg: Formed'in thev outer 'surface' 'of'V the-'rib immediately around the Yopening 24 is-a"- seat126, and'formedin the rib I4 at the Venc'iremoteffromtheo'pening 24, is an aligning opening I3I. Carri'edby the leg 20'at the end thereof'fremote from the/#opening 24 is an apron `28"'wh`ich" as illustrated inv the Adrawings isibent .inward-1y.L
rib Iii-at the junction ofthe portion which'lies 2,570,957 l f Y j to lie against the inner face of the leg 20 and bridge the portion of the groove I which lies alongthe leg. and thus cooperate withthe opening Main guiding a fastening device such as a nail N in the portion of the groove I6 which lies along the leg 20.
In the preferred form of the invention the end of the apron 28 remote from its junction With the leg 20 is equipped with a tapered tongue 30, which when the apronv is bent back to lie adjacent the leg 20 will enter the portion of the groove IB which lies along the leg 20 so as to engage the shank of the nail and hold the nail or other fastening device in assembled position within the clip.
In the modied form of the invention illustrated in Figure 7, the body I 2a which corresponds in all respects to the body I2 and is provided with a longitudinally extending outstanding hollow rib Ida which corresponds in all respects tothe rib I4. The body I2a is equipped at one;
end with a hook. not shown, and at its opposite end with a leg 20a which corresponds' to the leg 20 of ythe structure previously referred to. The junction of the portion of the rib Ilia which lies along the leg 20a, and the portion of the rib Illa which lies along the portion of the body I2a adjacent the leg 20a is provided with a seat 26a which corresponds with the seat 25 previously referred to. and the rib is also provided at this point with an opening corresponding to the opening 24. The opposite end of the leg I 4a is formed with one opening which corresponds to the opening 3! in the leg I4. The apron 28a of the modied form of the invention which corresponds to the apron 28 previously referred to lis provided at its end remote from the leg 20 with a fiat edge 32 which when the apron is folded back to bridge the open side of the rib Ida and lie against the leg 20a. it will serve simply as a guard to prevent contact of a fastener passing through the hollow portion of the rib which lies along the leg 20a from engaging the insulation of an insulated cable. Y Y
In use it will be understood that the device assembled with a fastener. such as a nail N is placed over the cable orother device to be supported so that the cable or the like is received in the recess 22. The fastener, is then driven home and it will be evident that the apron 28 and tongue 30 will effectively serve to hold the fastening device on the cable and out of contact with the insulation of the conductor, and the cable will be clamped firmly against the support S.
While in the foregoing there has been shown and described the preferred form of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
