Abstract
Abstract A clip is disclosed for insertion in a hole in the side of a paving form. A paper sleeve, diamond-shaped or rectangular in cross section, covers one leg of a tie bar, and the sleeve is supported in the clip. After a slab is poured and the form is removed, the clip and hole identify the position of the tie bar, which is pulled outwardly in preparation for the next pour. The rectangular protective sleeve can be used without the clip, in that it positions the leg of the tie bar closely adjacent the paving form, without the interposition of extra concrete around the edges of the sleeve.

Total Claims: 14
Claim 1
Independent Claim
106 words
The combination of a paving form containing apertures and: a support clip, having hanger and restraining portions for retaining the clip in one of the form apertures, and a support portion connected between the hanger and restraining portions; a tie bar, having a first leg and a second leg extending at substantially right angles to the first leg; and a protective sleeve, substantially enclosing one leg of the tie bar and received in the support portion of the support clip, which sleeve is formed of a material readily broken open to expose the tie bar after concrete is poured on the other side of the sleeve.
Claim 2
Dependent Claim
106 words
The combination of a paving form containing apertures and: a support clip, having hanger and restraining portions for retaining the clip in one of the form apertures, and a support portion connected between the hanger and restraining portions; a tie bar, having a first leg and a second leg extending at substantially right angles to the first leg; and a protective sleeve, substantially enclosing one leg of the tie bar and received in the support portion of the support clip, which sleeve is formed of a material readily broken open to expose the tie bar after concrete is poured on the other side of the sleeve.
Claim 3
Dependent Claim

Dependent Claim
22 words
The combination of claim 5, in which the support portion of the protective sleeve is formed to accommodate the diamond-shaped protective sleeve.
Claim 9
Dependent Claim
143 words
The combination of a paving form containing a plurality of apertures, spaced at intervals along the form: a support clip, having hanger and restraining portions for retaining the clip in one of the form apertures, and a support portion connected between the hanger and restraining portions, said hanger portion being shaped generally like an inverted U, and said restraining portion providing a force against the paving form, to maintain the protective sleeve abutting the form; a tie bar, having a first leg and a second leg extending at substantially right angles to the first leg; and a protective sleeve, substantially enclosing one leg of the tie bar and received in the support portion of the support clip, which sleeve is formed of a material readily broken open to expose the tie bar after concrete is poured on the other side of the sleeve.
Claim 10
Dependent Claim
143 words
The combination of a paving form containing a plurality of apertures, spaced at intervals along the form: a support clip, having hanger and restraining portions for retaining the clip in one of the form apertures, and a support portion connected between the hanger and restraining portions, said hanger portion being shaped generally like an inverted U, and said restraining portion providing a force against the paving form, to maintain the protective sleeve abutting the form; a tie bar, having a first leg and a second leg extending at substantially right angles to the first leg; and a protective sleeve, substantially enclosing one leg of the tie bar and received in the support portion of the support clip, which sleeve is formed of a material readily broken open to expose the tie bar after concrete is poured on the other side of the sleeve.
Claim 11
Dependent Claim
14 words
