Abstract
Abstract There is disclosed a work clamp and tool guide assembly which comprises a base plate, a crossbar secured to, and extending transversely across, the undersurface of the base plate, first and second upright posts, one each at opposite ends of the crossbar, a guide rail with distal apertures received over the first and second upright posts and locks to fixedly secure the guide rail at preselected heights. The workpiece is clamped between the guide rail and the base plate and can be oriented for right angle cuts by a fence which extends along at least one side of the base plate. A work tool such as a router, saw and the like can be guided across the surface of the workpiece with its edge against the guide rail.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A work clamp and tool guide assembly with a base plate which comprises: (a) a base plate; (b) a crossbar having distal vise means to secure said crossbar to the undersurface of said base plate at the forward edge of said base plate; (c) first and second upright posts, one each located and fixedly secured at an opposite end of said crossbar; (d) a guide rail having a substantially greater depth than width, a smooth, unbroken vertical guide surface, and a smooth, unbroken clamping undersurface, and coextensive with said crossbar with distal, transverse through bores slideably received over said first and second upright posts; (e) guide rail locking means operatively engaging each of said posts to fixedly secure said guide rail at adjustable positions thereon, and (f) a fence fixedly secured to said base plate and extending along one edge of said work piece orthogonal to and rearward of said clamp and tool guide assembly.
Claim 2
Dependent Claim
155 words
A work clamp and tool guide assembly with a base plate which comprises: (a) a base plate; (b) a crossbar having distal vise means to secure said crossbar to the undersurface of said base plate at the forward edge of said base plate; (c) first and second upright posts, one each located and fixedly secured at an opposite end of said crossbar; (d) a guide rail having a substantially greater depth than width, a smooth, unbroken vertical guide surface, and a smooth, unbroken clamping undersurface, and coextensive with said crossbar with distal, transverse through bores slideably received over said first and second upright posts; (e) guide rail locking means operatively engaging each of said posts to fixedly secure said guide rail at adjustable positions thereon, and (f) a fence fixedly secured to said base plate and extending along one edge of said work piece orthogonal to and rearward of said clamp and tool guide assembly.
Claim 3
Dependent Claim
48 words
The assembly of claim 1 wherein said vise means comprises first and second flanges, one each, mounted transversely of said crossbar, at opposite ends of said crossbar, and screw clamp means threadably received in one of said flanges whereby said crossbar can be secured to said base plate.
Claim 4
Dependent Claim
18 words
The assembly of claim 1 wherein said crossbar is secured to said base plate orthogonally to said fence.
Claim 5
Dependent Claim
18 words
