, l This invention relates to an improved drive rlngiof the type used by electricians, for example, to hang wires or cables to supporting surfaces. Driverings of theftypehere under consideratienjare, in general, well known and have been,
used for many years for different types of electrical installations. It is prerequisite for many jobs thatjthe drivering be galvanized soas to be abletofwithstand the corrosive effects of high humiditypr other factors obtaining at the place o'finstallation. Ithas been found that'in comirierciallyavailable"drive rings a small chip of I the galvanizing material forms between'the eye- 1 let'foflthe ring and the collar of the nail when thefl ing andhail are assembled. When the I mechanicdrives'the drive ring into its supporting position, his repeated hammer blows frequently dislodge this chip, and not infrequently the chip flies intothe mechanics face, sometimes injuring his eyes. It is accordingly among the objects of thisinvention to provide an improved drive'ringwhich obviates the foregoing disadvantage, among others.
In the drawing, wherein are shown three possible embodiments of my invention,
Figured is a perspective view of the drivering;
I iiFigurez-zais an .enlarged top plan view, of the drive ri uFigure 31isan enlargedbottomplan view of the drive ring Q.-- i

Figure 8 is a horizontal section taken along the line 8-8 of Fig. 7.
Similar reference characters refer to similar parts throughout the views of the drawing.
In accordance with one embodiment of my invention, the drive ring comprises a generally U-shaped member or loop, oneend of which is bent to form an eyelet through which the nail member of the drive ringis forced. This nail 2Claims. (Crus -71 member includes a collar, preferably nearer one end of the nail than the other, and between this collar and the pointed end of the nail, the shank of the nail is slightly enlarged to a diameter slightly greater than the diameter of the eyelet on the loop. The rest of the nail shank is of substantially the same diameter, or perhaps of slight- 1y smaller diameter than the eyelet. Thus the nail may be slid freely through the eyelet until its enlarged shank portion enters the eyelet. This ,portion is then forced into the eyelet, but it is of such short axial length that there is in sufficient galvanizing material to gather together and form achip between the eyelet and the col.- lar ;when the collar is firmly seated against the eyelet. I
Referring now to Figure l of the drawing, the
drive ring comprisesa generally U-shaped mem-,
ber or loop, generally indicated at I0, havinganl; eyelet ll formed on one' end thereof, through, which a nail, generally indicated at I2,extends.' Loop I0 comprises two legs I3 and ld joined we base I5, eyelet II beingformed on the endof leg I3. The diameter of theeyelet is preferably held within relativelynarrowtolerances, andmay have for example, diameter of .130 in. V
Still referringlto FigureLleg I4 ofloop I0 is bent inwardly somewhat toward leg I3 but, as shownin Figure 2,. out of a vertical plane pass ingthrough leg I3. Thus, theloop-legs I3 and I4, make installationpf the wire or cable to be suspended by the drive ring a very simple matter,
as such, cable can either be threaded through the loop, orcan ,bepassed between leg I4 and the q-ter vend I'm of. nail I2, as is desiredor ex:
peditiousa In other words, withleg I4 bent as described, an access opening I 6 (Figures 2,-a'nd 3 between leg I4 and-nailqend I 2a is provided for the ready reception-of awire or cable not thicker than the dimension ofthis opening. I The open-. ing Iaccordinglygreatly facilitates, the suspension, ofthe-wire or cable, andalso. advantageously, displaces the freeendof leg II l oftheeyeletfrom the nail h fidullmwhich is ,tobe struck bye,
hammer when driven into the wall.
As shown in Figure 4, nail I2 includes a pointed end I21) and a collar I! which is preferably positioned nearer the nail head In than the pointed end I 2b. Adjacent collar I! the shank of thenail is slightly enlarged, as at I8, and preferably includes a tapering portion I8a which varies in thickness from the diameter of portion I8 to the diameter of the nail shank. For example, if the nail shank measures .120 in. in
diameter, enlarged portion I8 may advantageously have a diameter of .130 in. Of course, the difference in diameter of the nail shank and portion I8 may be varied within reasonable limits, depending on particular conditions, or difierent sizes of drive rings.
Prior to assembly of loop I0 and nail I 2, the two parts are galvanized in a customary manner. This, of course, decreases somewhat the diameter of eyelet II, and increases somewhat the diambe slightly greater than that of the eyelet, thisportion of the nail must be forced through the eyelet until collar ll rests or abuts thereagainst.
Inasmuch as the axial length of enlarged nail portion l8 preferably approximatesthethickness oi the wire forming eyelet II, however, only approximately one-half of the enlarged portion will be engaged by the inner diameter of the eyelet during the final assembly operation. The extent of this engagement is so slight that no chip of galvanizing material will form, but yet the nail and eyelet are securely heldtogetherw With the nail l2 and loop 10 thus assembled, itwillbe seen (Figure 1) that loop leg 13 extends substantially at 'right angles to nail; I2, while loop leg 14 is directed somewhat inwardly toward eyelet H and is accordingly not parallel to leg I3. This feature, together with the bent-over characteristic of leg l4, as best shown in Figures 2 and 3, provides a highly efiicient loop .or
'ringfor the reception andretention of the wire or cable. Furthermore, when the electrician installs the drive ring, there is nothing in the immediate vicinity of the nail head 12a to impede ordeflect his hammer blows, and accordformed as by knurling that portion-of the nail:
This typeof en'- largement has certain advantages under given conditions, and upon being forced" through the shank adjacent collar l1.
' loop eyelet, effectively maintains the loop and nail in properly related assembly.
Still another manner of forming nailportion is shown in Figures '7- and 8; "As
shown in Figure'I; an enlarged portion ZU 'may b'e formed-by scoring or grooving that portion of the nail shank adjacent collar l'l by a suitabletool' to-form valleys 21 r and adj acent ridges 22, these rid'ges extending beyond the diameter of the the enlarged" nail shank, and accordingly forming the characteristic enlargement which, when forced through the loop eyelet, maintains the parts in properly related assembly.
Accordingly it may be seen that I have provided a drive ring which attains the several objects set forthv in a.- thoroughly. practical and efficient manner. a
I claim:
1. A drive ring having one end thereof bent back on itself to form an eyelet, and a nail extendable through said eyelet, said nail being thickened at a portion spaced from its pointed end to adimension slightly larger than the dimension of saidv eyelet, that portion of the nail between its thickened portion and its pointed end having substantially the same diameter as said eyelet, whereby the nail may be easily slid through said eyelet to said thickened portion and the thickened portion thereafter forced into said eyelet to retain said eyelet and nail in assembled relation, at least the thickened portion of said nail being galvanized. v
2. A drive ring having, one end thereof bent; back on itself to form an eyelet, a nail extendable, through said eyelet, said nail being thi'ckenedat. a portion spaced from its pointed end tola dimenj-J sion slightly larger than the dimension'fof said,
. eyelet, that pozrtion of the nail. between. its, thickened portion and its pointed end vhavingj substantially the same diameter as, said. eyelet;j whereby the nail may be easily slid through said} eyelet to said thickened portion and. the. thickened portion thereafterforced into said eyelet to; retainsaid eyelet and nail in assembled relation} at least the thickened portion of said nail'beingj galvanized, and a stop collar on saidnail at'the. outer end of said thickened portion to limit'pas; sage of saidunail' through said eyelet.
