Abstract

In the casting of concrete pipe, etc. the reenforcing mesh must be kept in spaced relation to the form during the introduction of the concrete. This invention pertains to a novel spring wire spacer attachable to and detachable from the mesh and having a projection engageable with the form to space the mesh properly.

Claims

1. An article of the class described, comprising a one-piece element of spring wire having a basic component configured to provide first and second legs extending toward and joined together by a bight, said legs and bight lying generally in a common plane and each leg having an end portion remote from said bight, said end portions lying generally on a line included in said plane and the bight lying to one side of said line, an elongated lever arm projecting in one direction away from and generally perpendicular to the plane and having a junction with the first leg portion, a relatively short third leg projecting away from the plane in the direction opposite to that of the lever arm and generally perpendicular to the plane and having a junction with the second leg end portion, said third leg having an end portion, a spacer leg spaced from the plane at the side thereof from which the third leg projects and having a generally right angular junction with the third leg end portion and extending from said third leg end portion in substantially '"'"''"'"''"'"''"'"'right-angle'"'"''"'"''"'"''"'"' relation to the aforesaid line and lying on that side of the line opposite to that at which the aforesaid bight lies.

2. The invention defined in claim 1, in which the end of the lever arm remote from the plane is formed As a hook.

3. The invention defined in claim 1, in which the bight is in the form of a V and the first and second legs converge toward the V at an angle on the order of 90*.

4. The invention defined in claim 1, in which the spacer leg is related to the third leg at an angle on the order of between 82* and 88*.

5. The invention defined in claim 1, in which the relationship between the lever arm and the spacer leg is substantially '"'"''"'"''"'"''"'"'9 o'"'"''"'"'clock'"'"''"'"''"'"''"'"' and viewed endwise along a line lying in said plane and extending between the respective junctions between the first leg and lever arm and the second and third legs.
