Claim 5
Dependent Claim
55 words
The machine in claim 1 wherein said guide and spacer means has portions effectively offset toward said slab support means with respect to said cutting blade means to cause said portions to engage the slabs first, and has other portions effectively offset away from said slab support means with respect to said cutting blade means.
Claim 6
Dependent Claim
61 words
The machine in claim 4 wherein said second guide and spacer means has portions effectively offset toward said slab support means with respect to said binder plate retention means to cause said portions to engage the slabs first before plate engagement, and has second portions effectively offset away from said slab support means with respect to said binder plate retention means.
Claim 7
Dependent Claim
103 words
Apparatus for assembling panels and interconnecting binder plates into structural building units comprising: panel support and retention means arranged to retain a pair of panels in spaced parallel relationship; binder plate insertion means adjacent said first means, having binder plate retention means and having spreader and alignment means for pushing the panels apart against said panel retention means and aligning them with respect to said insertion means, said insertion means being shiftable toward the space between said panel support and retention means sufficiently to spread the panels and push the binder plate edges into the panels; and power-shifting means for said insertion means.
Claim 8
Dependent Claim
103 words
Apparatus for assembling panels and interconnecting binder plates into structural building units comprising: panel support and retention means arranged to retain a pair of panels in spaced parallel relationship; binder plate insertion means adjacent said first means, having binder plate retention means and having spreader and alignment means for pushing the panels apart against said panel retention means and aligning them with respect to said insertion means, said insertion means being shiftable toward the space between said panel support and retention means sufficiently to spread the panels and push the binder plate edges into the panels; and power-shifting means for said insertion means.
Claim 9
Dependent Claim
40 words
The apparatus in claim 6 wherein said portions of said spreader and alignment means are offset toward said panel support and retention means with respect to said binder plate retention means to cause said portions to engage the panels first.
