` BUILDERS STRAIGHT WIRE ANCHOR Filed May 3'l 1930 Patented Mar. 31', 1931 `vUNrrED STATES STONEWALL J. IVICSPADDEN, OF ALPINE, TEXAS BUILDERS STRAIGHT-WIRE ANCHOR Application led May 31, 1930. Serial No. 458,714.

The object of this, my present invention, is the provision of anchoring means for straight wires such as are employed for making concrete. forms or the like, and the object of the l invention is the provision of a simple means for this purpose which will grippingly engage with ends of wires, each cut at a similar length, and effectively hold such wires on and between a form o r the like.

A further object is the provision of a clamping means for this purpose that comprises a flared or substantially cone-shaped member divided in halves, the confronting faces of each half or section having intermeshing teeth, the said half or section designed to receive the ends of form wires therebetween and the said sections being removably held together and the teeth thereof in biting engagement with the ends-of the wire through the medium of a ring which wedgingly engages the clamp.

To the attainment of the Vforegoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure l is a perspective view illustrating the application of my improvement in connection with a concrete form.

Figure 2 is a transverse sectional view therethrough.

Figure 3 is an enlarged side elevation ofthe improvement.

Figure 4; is a face view looking toward the toothed face of one of the sections of the clamp.

Figure 5 is a sectional view approximately on the line 5-5 of Figure 3.

While I have illustrated, in Figures l and 2 of the drawings, my improvement employed for holding the ends of wires that sustain the vertical posts in a concrete form against the longitudinal boards thereof, it is to be understood that the improvement is not to be restricted to this particular arrangement as 4:5 the same may be successfully yennployed in other connections where the ends of wires either permanently fixed or removable are to be clamped. Y

When employed in connection with a form it will be further understood as the concrete sets the clamps may be removed fromv the lower wires and employed to engage with the upper wires of the form. It will be also noted that the wires may be all cut the same length.

The side boards of a concrete form are indicated by the numeral l, the vertical posts by the numeral 2 and the spacer plates by the numeral 3. The spacer plates are, of course, removable and also the uprights 2 are not nailed or otherwise connected to the boar-ds l. At determined spaces throughout the length of the posts or uprights 2 and the boards 1 I bore alining holes and through these holes there are passed the usual holding wires 4. These wires, as stated, are all of the same length and have their ends projecting each a suitable distance beyond the posts or uprights 2 and it is these ends that the clamp constituting my improvement engages.

As disclosed by the drawings the clamp comprises a flared or substantially coneshaped member which is round in plan. The clamp comprises two halves or sections 5, re-

v spectively, and the flat confronting faces of these sides are provided with transversely ar- "15 ranged intermeshing teeth 6 and between the sections 5 the ends of the wires 4 are received. The widened ends ofthe clamps are forced against the posts or uprights 2V andV the sections 5 are slightly canted on each other as disclosed by Figure 5 of the drawings. Thereafter I arrange over the outer or nose end of the clamp a metal ring 7 and this ring is forced longitudinally over the clamp to bring the sections 5 thereof toward each other to cause the interengaging teeth to bite into the wire but such frictional engagement between the teeth and wire is not sufficient to sever the wire as the confronting faces of the clamps are at all times retained angularly lwith respect to each other, as disclosed by Figure 5 ofthe drawings. Y

It is thought the simplicity and advantages of the construction will be apparent to those skilled in the art to which such invent-ion re- A lates so that further detailed description will not be required. Y

Having described the invention, I claim:

A means for clamping the projecting ends of wires to afform or the like, comprising a 1509 substantially frusto conical member divided into halves and each section having its Hat Confronting face provided with transverse teeth to receive the Wire therebetween and a Wedge ring arranged over the clamp for holding the confontng faces of the clamp in biting engagement with the Wire butin angular relation to each other.

In testimony whereof I aix my signature.

STONEWALL J. MCSPADDEN.
