WAGNER, on REMSEN', IOWA FASTENING DEVICE Application filed August 14, 1929. Serial No. 385,952.

This invention relates broadly to fastening devices, and has as its primary object the V provision of a device of this character, es-

pecially adapted for use with chairs, and 5 especially designed for use as a complemental anchor or fastening member for securing two ointed members in interlocked engagement.

A still further object of the invention is to provide a fastening device or anchor of this character which will be found especially useful for use with chairs for securing either the round of the chair in jointed or interlocked engagement with the leg, or the legs of the chair in jointed or interlocked engagement with the seat of the chair.

A still further object of the invention is to provide a fastening device of this character consisting mainly, in an elongated rod or bar formed'at one end with a prong or nailing member adapted to be driven into either the leg or round of the chair depending upon the purpose for which the device is to be used, and at its opposite end the rod is provided with either a similarly shaped prong or in lieu thereof provided on said opposite end with threads whereby the said end of the. de vicemay be screw-threaded into the leg or seat of the chair, depending of course, upon the purpose to which the device is put.

A still further object of the invention is to provide a device of the character abovementioned, which is simple in construction,

strong, durable, inexpensive, constituting! but 3 few parts, thoroughly practical, reliable, and eflicient in operation, and otherwise well adapted for the purpose designed.

Other objects and advantages of the invention will become apparent during a study of the following description taken in connection with the accompanying drawings; wherein:

Figure 1 is a view partly in section and partly in elevation of a chair seat and leg. showing the same in jointed or interlocked engagement and showing one embodiment of my invention applied thereto.

Figure 2 is a view partly in section and partly in elevation of a chair leg and supporting round, showing the application thereto of that form of the invention first illustrated in Figure 1.

Figure 3 is a perspective view of the fastening or anchoring device, the manner or use of which has been illustrated in Figures 1 and 2.

Figure 4: is a view similar to Figure 2, and showing the application of a modified form of the device,

Figure 5 is a perspective view of that form of device used in Figure 4.

Figure 6 is a fragmentary side elevation of a chair leg and supporting round therefor, and showing the application of another form of the invention.

Figure 7 is a perspective view of that form of the invention used in Figure 6.

Referring to the drawings, attention is first invited to that form of the invention illustrated in Figures 1 to 3 inclusive.

As shownin Figure 3, that'form of the device used in the figures just mentioned comprises an elongated shank 5, which shank may be of cylindrical cross section and formed of any suitable durable metal. At one end thereof the shank 5 is provided with a laterally disposed prong or piercing member 7 extending at right angles tothe shank. The prong or piercing member 7 as shown comprises a shank 6 of substantially rectangular configuration in cross section and tapering longitudinally to terminate in a substantially diamond-shaped piercing head or point 8, providing inwardlyfrom the free end of the member 7 oppositely extending lateral shoulders 8 serving to secure the head 8 embedded in the Work, and thereby retain the fastener against lateral displacement relative to the work. 7

At its opposite end the shank 5 merges into a point, and at its pointed end is suitably threaded to provide what may be termed a screw 9. 7

When using the device just described for securing a chair legto the seat thereof, it. will be seen, from a study of Figure 1, that the chair leg L is in jointed or locked engagement with the chair seat S through the medium of the usual mortised joints. The prong 7 is hammered into the leg L adjacent the jointed end of the leg, the diamond shaped head 8 insuring a positive gripping action of the piercing member with the leg.

The screw 9 of the member is screwthreaded into the chair seat S, with the shank 5 extending parallel to the chair leg L.

When used as shown in Figure 2, that is, for maintaining the round R of the chair in mortised jointed relation with the leg L, the prong 7 is driven into the round in the same manner as it is driven into-the. leg L in Fig.- ure 1, while the screw end 9 is threaded into the leg L, the shank 5 lying in substantially a horizontal plane and parallel to the round Attention is now directed to Figures 4; and 5, wherein it will be seen that the device as therein illustrated, comprises a shank 5 provided at one end with a piercing prong 7 similarin every detail to the piercing prong 7 of the member shown in Figure 3. However, at-its'opposite end the shank 5 is laterally ofi'set as at 10 and is then continued longitudinally to terminate in a piercing prong 11, the details of construction of which is in every way similar to the prong 7 In: using. the-devices just described, a prong 7 is hammered or otherwise driven into the round R? which round is in mortised jointed engagement with the leg L of the chair. Prior-to which embedding of the prong 7 into said round R. the prong 11 is driven or otherwise passed into the leg L, the offset portion 10 being imbedded in the leg, while the shank portion 5 extends into a suitable cavity or recess 12 extendinglongitudinally of the round R.

Attention is now directed to Figures 6 and 7, and it-willbe seen that the device as illustrated in these figures comprises a shank 5" bent laterally in the same direction at its opposite ends as at- 13, which lateral directed end 13 terminates in piercing prongs 7", the said prongs 7. being in every detail of construction the exact duplicate of the piercing prongs 7 and 7. A more detailed description of the prongs 7 is therefore deemed unnecessary.

Thusit will be seen that the device as just described and clearly illustrated in Figure 7 is of substantially U-shaped formation, the legs of the U constituting the prongs 11". In using this embodiment of the invention, one of the prongs 7 is pierced or driven into the horizontal member B! which may be the round'of a chair, while the other prong 7 is driven into the vertical member L which may be the leg of a chair. Thus it will be seen that the shank 5 extends parallel to themember R along the side of the member for the greater length of the shank R", the remaining portion of the shank 5 extending transversely of the vertical member 11".

From the foregoing then, it will be seen that .the device as illustrated in Figures 1 to 3 inclusive is especially designed and will be found the most desirable of the species for securing either the round of a chair to the leg of the chair, or the leg of the chair to the seat of the chair.

The forms of devices shown in Figures 5 and 7 could of course, be used for the same purpose as that form of'the invention illustrated in Figure 3 however, these last described forms of the invention are best suited for various. andlsundry purposes, wherein a device of this nature can be employed to advantage for securing any two jointed members in jointed engagement.

Even though I have herein shown and de scribed the preferred embodiments of my invention, itis to be understood'that the same is susceptible to changes fully comprehended by the spirit of the invention as herein described, and the scope of the appended claims.

Having thus described my invention, what I wish to claim as new is:

1. A fastening device for securing two jointed members in their jointed relationship, comprising an elongated resilient shank provided with threads adj acentone end thereof for threadedly engaging oneof the members and remote from said threads being provided with an integral prong extending at right angles thereto and terminating, in a spear head adapted to be embedded in the other of said jointed members.

2. A fastening device formedfrom a single length of wire. or like resilient material and comprising aflexible shank having, a threaded tapered end, and remote from said end having a lateralprojection merging into a pointed end and providedwith oppositely extending lateral shouldersinwardly from said pointed end.

3.. A, fastening device for. the purpose specified comprising a. flexible shank having. one end tapered and screw threaded, and at its other end being bent laterally to provide a lateral projection terminating in a spear head.

In testimony whereof I aflix my signature.

CHARLES B. WAGNER.
