Abstract
Abstract A work table for a saw includes, a base member supporting elongated guide channels at an elevated position relative to the base member, a saw mounting plate slidably supported in the guide channels, the plate having a rectangular opening over which the base plate or shoe of a commercially available portable power saw is secured, a work supporting plate capable of being removably secured in alternative positions either below the saw supporting plate in which the table operates in the docking saw mode, or above the saw supporting plate in which the table operates in the bench saw mode, the work supporting plate having stops by means of which the saw supporting plate is secured in position when the work table is operating in the bench saw mode. The work supporting plate is formed with slots for receiving the blade of the saw in both modes of operation and for receiving mitre guages and work stops. The work supporting plate is convertible to two different ranges of widths by securing the plate to the work table in different positions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A work table for a saw comprising, a pair of spaced horizontally extending guide members secured to support members in a position that is raised from a support surface, a saw supporting plate engaged with and guided by said guide members for movement in a horizontal plane, a work supporting plate having an elongated slot which in use receives the saw blade of a saw secured to said saw supporting plate, and means on said guide support members for securing said work support plate in alternative positions below said saw supporting plate in which the work table can operate in a docking saw mode and above said saw supporting plate with the saw blade adapted to project upwardly through said slot in which the work table can operate in use in a bench saw mode, and means on said table for preventing movement of said saw supporting plate relative to said guide members when the table is in the bench saw mode.
Claim 2
Dependent Claim
162 words
A work table for a saw comprising, a pair of spaced horizontally extending guide members secured to support members in a position that is raised from a support surface, a saw supporting plate engaged with and guided by said guide members for movement in a horizontal plane, a work supporting plate having an elongated slot which in use receives the saw blade of a saw secured to said saw supporting plate, and means on said guide support members for securing said work support plate in alternative positions below said saw supporting plate in which the work table can operate in a docking saw mode and above said saw supporting plate with the saw blade adapted to project upwardly through said slot in which the work table can operate in use in a bench saw mode, and means on said table for preventing movement of said saw supporting plate relative to said guide members when the table is in the bench saw mode.
Claim 3
Dependent Claim
42 words
The work table of claim 1, wherein said guide members are channels arranged with their open sides facing each other, at least portions of the longitudinal edges of said saw supporting plate being engaged in said channels for sliding movement relative thereto.
Claim 4
Dependent Claim
42 words
The work table of claim 2, wherein said longitudinal edges have bearing blocks secured thereto for engagement with said channels, said blocks being adjustable laterally to increase or decrease the sliding force required to move said saw supporting plate along said channels.
Claim 5
Dependent Claim
30 words
The work table of claim 2, wherein said work supporting plate has at least one work stop removably secured thereto on one side of said slot and extending perpendicularly thereto.
Claim 6
Dependent Claim
19 words
The work table of claim 4, wherein there are two work stops, one on either side of said slot.
Claim 7
Dependent Claim
73 words
The work table of claim 4, wherein said work supporting plate is formed with a slot running parallel to said first mentioned slot and a further slot extending perpendicularly to said first mentioned slot on the other side thereof to said parallel slot, said slots being adapted to receive a slider on a mitre gauge, said slider being capable of being clamped in any position in either slot by means of clamping means.
Claim 8
Dependent Claim
53 words
The work table of claim 6 wherein said parallel running slot is adapted to receive said saw blade in the bench saw mode by securing said work supporting plate in a position which is rotated through 180° to the said bench saw mode position, whereby the table has a greater rip width capacity.
Claim 9
Dependent Claim
36 words
The work table of claim 3, wherein said channels are C-section channels and said bearing blocks have grooves receiving the flanges of said C-section channels whereby the channels are tied together by the saw supporting plate.
