3. In a wedge having a central portion that tapers in cross section from one end to the other, wing members formed on said central portion, said wing members lying in spaced relation to said central portion and tapering towards the same and said wings terminating midway between the upper and lower edges of the Wedge, whereby to form pockets to effect additional Wedging functions. 7

4. In a wedge, a central portion tapered in cross section from one end to the other, wings formed on opposite ends of said central portion, said wings lying in spaced relation to said central portion, barbs formed on said wings, to aid in holding them in predetermined position and said wings terminating midway between the upper and lower edges of the wedge, whereby they disappear when the wedge is assembled.

5. In a wedge, a central portion tapered from one end to the other, wings formed on opposite sides of said tapered portion, whereby to effect additional wedging surfaces, said wings terminating midway between the upper and lower edges of the wedge, and notches formed on said Wings to aid in holding them in predetermined position.

6. In a wedge, a central portion tapered in cross section from one end to the other, Wings formed on opposite ends of said central portion, said wings lying in spaced relation to said central portion, barbs formed on said wings, to aid in holding them in predetermined position, and said wings terminating midway between the upper and lower edges of the wedge, whereby they disappear when the Wedge is assembled.
