Abstract
Abstract An integrally molded synthetic resin mitre box has an elongated base portion, rigid post members spaced along one side thereof and a rigid guide member on the opposite side thereof. The guide member and posts have aligned vertical channels therein opening at the top surface thereof and providing guide channels for a saw blade at varous angular orientations relative to the longitudinal axis of the mitre box. The post members and guide member are of generally hollow construction with inverted columnar portions providing the channels. The base portion is provided with apertures, and a depending lip is provided along one side for secure placement against a worktable or the like.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
157 words
A mitre box comprising an integrally molded structure of synthetic resin having an elongated base portion, a plurality of rigid post members spaced apart along one side thereof, and a rigid elongated vertically extending guide member on the opposite side thereof aligned with one of said post members, said guide member and said one post member having aligned vertical channels therein extending perpendicularly to the longitudinal axis of said structure, said guide member having at least one additional vertical channel therein spaced along the length thereof from said first mentioned channel therein and extending at an angle to the longitudinal axis of said structure, another of said guide posts having a vertical channel therein aligned with the angular channel of said guide member, said channels opening at the top surface of said posts and guide member, said post members and guide member each having a peripheral wall extending upwardly from said base portion and a cavity therewithin.
Claim 2
Dependent Claim
157 words
A mitre box comprising an integrally molded structure of synthetic resin having an elongated base portion, a plurality of rigid post members spaced apart along one side thereof, and a rigid elongated vertically extending guide member on the opposite side thereof aligned with one of said post members, said guide member and said one post member having aligned vertical channels therein extending perpendicularly to the longitudinal axis of said structure, said guide member having at least one additional vertical channel therein spaced along the length thereof from said first mentioned channel therein and extending at an angle to the longitudinal axis of said structure, another of said guide posts having a vertical channel therein aligned with the angular channel of said guide member, said channels opening at the top surface of said posts and guide member, said post members and guide member each having a peripheral wall extending upwardly from said base portion and a cavity therewithin.
Claim 3
Dependent Claim
23 words
The mitre box in accordance with claim 1 wherein said cavity of each of said post members and guide member is downwardly opening.
Claim 4
Dependent Claim
42 words
The mitre box in accordance with claim 2 wherein said post members and guide member have sidewall portions extending transversely of the length of the channels therein and a bottom wall portion extending between said sidewall portions to provide a closed channel.
Claim 5
Dependent Claim
43 words
The mitre box in accordance with claim 3 wherein said post members and guide member each include inverted columnar portions extending downwardly from the top wall thereof and within the periphery thereof to provide said channels with their side walls and bottom walls.
Claim 6
Dependent Claim
21 words
The mitre box in accordance with claim 1 wherein said channels extend to adjacent the top surface of said base portion.
Claim 7
Dependent Claim
95 words
The mitre box in accordance with claim 1 wherein there is provided at least one post member spaced to either side of said post member containing the perpendicularly extending channel, said spaced post members having channels therein of different angular orientation than that of the other and cooperating with aligned channels in said guide member, said guide member having a multiplicity of channels spaced along the length thereof cooperating with said channels of said spaced post members and providing to a saw received therein different angular orientations relative to the longitudinal axis of said structure.
Claim 8
Dependent Claim
27 words
The mitre box in accordance with claim 1 wherein said structure includes upstanding guide flanges spaced along said opposite side thereof and spaced from said guide member.
Claim 9
Dependent Claim
33 words
The mitre box in accordance with claim 1 wherein said base portion includes a plurality of apertures for seating threaded fasteners or the like to secure said mitre box to a support surface.
Claim 10
Dependent Claim
28 words
The mitre box in accordance with claim 1 wherein said base portion has relatively large spaced apertures extending therethrough to permit sawdust and the like to fall therethrough.
Claim 11
Dependent Claim
54 words
The mitre box in accordance with claim 1 wherein said structure includes a depending lip portion extending below the plane of said base portion and along one side thereof whereby the inside surface of said lip portion may be pressed against the edge of a worktable or the like to provide firm support therefor.
Claim 12
Dependent Claim
137 words
The mitre box in accordance with claim 1 wherein there is provided at least one post member spaced to either side of said post member containing the perpendicularly extending channel, said spaced post members having channels therein of different angular orientation than that of the other and cooperating with aligned channels in said guide member, said guide member having a multiplicity of channels spaced along the length thereof cooperating with said channels of said spaced post members and providing to a saw received therein different angular orientations relative to the longitudinal axis of said structure and wherein there is included upstanding guide flanges spaced along said opposite side thereof and spaced from said guide member, the opposing wall faces of said posts, guide member and flanges being substantially vertical to permit stable seating of a workpiece thereagainst.
Claim 13
Dependent Claim
80 words
The mitre box in accordance with claim 1 wherein said base portion includes a plurality of apertures for seating threaded fasteners or the like to secure said mitre box to a support surface and wherein said structure includes a depending lip portion extending below the plane of said base portion and along one side thereof whereby the inside surface of said lip portion may be pressed against the edge of a worktable or the like to provide firm support therefor.
