Abstract
Abstract A horizontal elongated and upwardly opening channel structure is provided and includes upstanding longitudinal sides interconnected by means of a bottom extending between and connected to the lower marginal portions of the sides. The sides include at least one pair of corresponding upwardly opening notches formed therein aligned along a path extending transversely of the channel structure and a pair of generally parallel guide structures are supported from and extend between corresponding upper marginal portions of the sides on opposite sides of the aforementioned notches with the opposite ends of the guide structures projecting outwardly of the remote sides of the sides. The guide structures are provided for guiding the supporting opposite side marginal portions of the support plate of a power saw therefrom for guided movement of the power saw along the guide structures with the cutting blade of the saw disposed in the aforementioned path and receivable through the aforementioned notches for cutting through a workpiece disposed in the channel structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A horizontal elongated and upwardly opening channel structure including upstanding longitudinal sides interconnected by means of a bottom extending between and connected to the lower marginal portions of said sides, said sides including at least one pair of corresponding upwardly opening notches formed therein aligned along a path extending transversely of said channel structure, a pair of generally parallel guide structures supported from and extending between corresponding upper marginal portions of said sides on opposite sides of said path with the opposite ends of said guide structures projecting outwardly of the remote sides of said sides, said guide structures being adapted to guidingly support opposite side marginal portions of the support plate of a power saw therefrom for guided movement of said plate along said guide structures with the cutting blade of said saw disposed in said path.
Claim 2
Dependent Claim
138 words
A horizontal elongated and upwardly opening channel structure including upstanding longitudinal sides interconnected by means of a bottom extending between and connected to the lower marginal portions of said sides, said sides including at least one pair of corresponding upwardly opening notches formed therein aligned along a path extending transversely of said channel structure, a pair of generally parallel guide structures supported from and extending between corresponding upper marginal portions of said sides on opposite sides of said path with the opposite ends of said guide structures projecting outwardly of the remote sides of said sides, said guide structures being adapted to guidingly support opposite side marginal portions of the support plate of a power saw therefrom for guided movement of said plate along said guide structures with the cutting blade of said saw disposed in said path.
Claim 3
Dependent Claim
40 words
The combination of claim 1, wherein said channel structure includes downwardly projecting opposite end leg means for supporting the channel structure in elevated position relative to a horizontal support surface upon which the lower ends of said leg means rest.
Claim 4
Dependent Claim
43 words
The combination of claim 2, wherein the opposite ends of said channel structure include downwardly opening socket defining structures supported therefrom, said leg means comprise opposite end upstanding elongated leg members whose upper ends are removably upwardly telescoped into said socket defining structures.
Claim 5
Dependent Claim
94 words
The combination of claim 3, wherein each of said socket defining structures includes a clamping jaw element shiftably supported therefrom on one side of the socket defined thereby for movement within the socket toward and away from the other side thereof, and adjusting means carried by each of said socket defining structures and operatively associated with the corresponding jaw element for adjusting the latter toward the other side of the corresponding socket, whereby to clampingly secure the corresponding leg member in the socket between said jaw element and said other side of said socket.
Claim 6
Dependent Claim
60 words
The combination of claim 4, wherein each of said socket defining structures includes peripherally extending wall portions, one of said wall portions including an opening formed therein, said jaw element of each socket defining structure loosely received through said opening, said adjusting means comprising a screw threadedly engaged with each socket defining member and abutted against the corresponding jaw element.
Claim 7
Dependent Claim
25 words
The combination of claim 1, wherein said bottom includes a plurality of transversely spaced channel members underlying extending along and secured to said bottom wall.
Claim 8
Dependent Claim
54 words
The combination of claim 1, including a panel member overlying and secured to said bottom wall, said panel member being constructed of a material which may be cut by a wood saw, the lower marginal portions of said notches being disposed above said bottom wall and below the upper surface of said panel member.
Claim 9
Dependent Claim
73 words
The combination of claim 1, wherein said sides include two pairs of upwardly opening notches formed therein with one pair of notches being generally centered relative to a path extending transversely of said channel member at right angles relative to the longitudinal centerline thereof and the other pair of notches being generally centered relative to a path extending transversely of said channel member angularly displaced generally 45° relative to the longitudinal centerline thereof.
Claim 10
Dependent Claim
40 words
The combination of claim 8, wherein said channel structure includes downwardly projecting opposite end leg means for supporting the channel structure in elevated position relative to a horizontal support surface upon which the lower ends of said leg means rest.
Claim 11
Dependent Claim
43 words
The combination of claim 9, wherein the opposite ends of said channel structure include downwardly opening socket defining structures supported therefrom, said leg means comprise opposite end upstanding elongated leg members whose upper ends are removably upwardly telescoped into said socket defining structures.
