SHEET-STOCK AXIALLY DRIVEN PERMANENT FASTENER Filed July 14, 194.1

' Application July 14, 1941, Serial No. 402,285
This invention relates to permanent securing means for axially driven fasteners within channels or bores provided therefor, and more particularly to such fasteners produced from sheetstock.
The objects-of "the invention are to provide 'a permanent securing meansfor sheet-stock fasteners adapted to be driven within passages provided therefor in fiber, metal or other stock that is less hard than the fastening device; -to provide for a sheet-stock fastener integral resilient portions having cutting shoulders rearwardly extending beyond the inner wall surface of. the path of the driven fastener; and to provide for such a fastener a shank of such form adapted to fit the particular passage prepared therefor. A
With reference to the accompanying drawing, the Figure 1 is an upright face view of the pre-- ferred form of the device; the Figure 2 is an upright side-view; the Figure 3 is a cross-section of.
and said twisting formation providing fin a cutting corner shouldert projecting the device on the line 3-4 of the Figure 2, the section of the device being illustrated in connection with the inner wall-surface of the-passage prepared therefor; the Figure 4 is an uprightface view of a modified form of device; the Figure 5 is an upright side view of the'device illustrated by'the next previous figure; the Figure 6 line 6-6 of the Figure 5, the sectionof the device being illustrated in connection with the inner wall-surface of the passage prepared therefor;
is a cross-section of the modified device on the the Figure 7 is an upright perspective view of a I further modified form of device; the Figure 8 is an upright side view'of said further modified form; the Figure 9 is a cross-sectien'of the device on the line !9 of the Figure 8, the section being illustrated in connection with inner wallsurface of the bore prepared therefor; and the Figure 10 is a diagrammatic sketch of detail;
Withmore particular reference to the accompanying drawing the numeral l designates the sheet-metal bodyof'the preferred form of the device illustrated by'the Figures 1, 2 and 3. The sheet-metal body leis provided in strips of any desired width and length and the side edges 2 and I of both extremities are transversely cut at intervals, as at '4, to provide at alternate out sections a series of fins 5 along said edges 2 and 3.
Following the cutting process, or simultaneously therewith, the fins l are formed and twisted up outof the plane of the body strip l and out of alignment with said edges 2 and teach fin i being divergently directed away from the free ends slightly beyond its respective edge 2 or 3. The
The socket or passage, designated by the inner wall-surface ID, for the driven insertion of the shank I of the device being determined and prepared, the free end 8 of the shank 8 is initially placed within the entrance to the passage until the pair of fins 5 adjacent said free end 9 obstruct the further entrance by reason of their cutting corner shoulders projecting beyond the path of the shank 8 and the inner wall-surface III of the passage, as illustrated by the Figure 3. Sumfrom their normal positions, with regard to the inner wall-surface l0, so that they, each pair in succession, are made to enter the passage until the shank 8 is fully driven home, the tension of resiliency causing each shoulder 8 to bear its cutting corner I against the wall-surface l0. Upon subsequent separating strain, such strain will be met and resisted by said cutting shoulders 6 digging into the inner wall-surface it of the passage and thereby establishing an'opposing abrupt shoulder II in the inner wall-surface it in locking engagement with each of the shoulders 6 of the fins I, thereby permanently secur ing the device within the passage prepared therefor, the opposing abrupt shoulders 6 and ll being shown diagrammatically by the Figure 10.
The modified device, illustrated by the Figures 4, 5 and 6, is quite similar to that of the pre- 'ferred form, excepting that its head IA and shank IA are formed from a single thickness of a sheet-metal body IA of which the head IA is formed by axially cutting into the end of the metal bodystrip IA with two equally spaced cuts and bending the two outer end portions 13 and IC inone right angled direction and the center 3A of the shank 8A are cut transversely-at equal of the strip I, as best illustrated by the Figure 2,
intervals and the cut sections are similarly formed as in the preferred form, excepting that, in form, the successive cut sections are twisted for each Y in alternate directions out of the plane of the sheet-metal body IA and out of alignment with the edges 2A or 3A and divergently directed toward the head 1A to provide the fins 5A. The manner of driving and securing the device within the inner wall-surface IDA of the passage prepared therefor is identical with that of the preferred form. I
The further modified form of the device, illustrated by the Figures 7, 8 and 9, is intended primarily for a bore into which the shank of the device .is .driven. The sheet-metal strip form of the body I and the head 1 is identical with that of the preferred form. The shank of this modified form, while it employs .the parallelly associated sheet-metal shank portions, as in the preferred form, is provided with only two fins 53 at the free end of said shank portions, each bent divergently upward and outward. The manner of driving and securing this modified form of the device within the bore provided therefor is very similar to thatof the preceding forms, except-v ing that, as illustrated by the Figure 9, the corners of the upturned fins 53 provide the cutting shoulders 60 that, as thedevice is driven within the inner wall-surface IOB of the bore, the resilient fins 5B are made to yield inwardly to admit the shank, and upon separating strain the cutting shoulders 60 dig into the inner wall-surface IOB thereby providing abrupt shoulders in said wall-surface that oppose the cutting shoulders 60 of the fins 5B.
I claim:

A. permanent driven fastening means comprising a folded strip of sheet-metal providing a closely associated double thickness of a shank; a head integrally formed at the folded extremity of the shank; a reduced width of the strip at the free ends of. the shank; resilient fins integrally formed within the side edges of both shank' portions by means of cuts at intervals therein perpendicular to the said side edges and a porbeing the outwardly twisted comer portion of said alternate sections directed divergently toward said head and normally extending beyond.
