Abstract

In combination with a saw machine having a relatively thin circular saw mounted upon an arbor with floating axial looseness and a saw guide defining a limiting control plane for guiding the leading edge of said saw, a splitter mounted for lateral movement and laterally positioned by the rear edge of said saw. A splitter for use in saw machines having a circular saw and comprising a pair of spaced contacts, each contact having a bearing surface for making contact with opposite sides of a circular saw, and a divider member having a plurality of resilient contacts that extend into a region above said spaced contacts and in trailing relation to the rear edge of a saw.

Claims

1. In combination with a saw machine having a relatively thin circular saw mounted upon an arbor with floating axial looseness and a saw guide defining a limiting control plane for guiding the leading edge of said saw, a splitter, means supporting said splitter adjacent the rear edge of said saw for lateral movement in a direction substantially parallel to said arbor, and means engageable with the rear edge of said saw for moving said splitter and maintaining said splitter in trailing relationship to the rear edge of said saw.

2. The saw machine of claim 1, said splitter having a pair of spaced guide plates disposed on opposite sides of said saw blade, the spacing between said plates being approximately equal to but slightly greater than the thickness of said saw blade, each guide plate providing an area of contact extending from the rear edge of said blade radially inward thereof.

3. The saw machine of claim 1, said splitter having a plurality of resilient contacts that extend into a region above the rear edge of said saw and occupy an area of splitting at least as wide as the kerf of said saw.

4. The saw machine of claim 3, certain of said plurality of resilient contacts projecting from one side of said splitter and certain other of said resilient contacts projecting from the opposite side of said splitter, the maximum lateral spacing between contacts on opposite sides being greater than the saw kerf of the saw, contacts on opposite sides of said splitter being moved relatively toward one another and resiliently stressed as cut pieces are moved through the machine.

5. The saw machine of claim 1, said saw having a large stiffening collar extending outward from the hub.

6. The saw machine of claim 1, said splitter comprising two plates, and means for disconnectably joining said plates to capture the rear edge of said saw.

7. The saw machine of claim 6, and further comprising a roll for transporting cut pieces through and beyond the saw, said roll being located in near proximity to the rear edge of said saw, and means for pivotally mounting each plate of said splitter from a support member vertically displaced relative to said roll, the bearing surfaces of said splitter being in front of said roll.

8. The saw machine of claim 7, and further comprising stop means for engaging the plates of each splitter and positioning the plates in pivotal and Guided relation to the rear edge of said saw, the pivotal fit between each plate of said splitter and said support member allowing the plates to be rocked upon the support member to move the splitter plates laterally and displace the plates from engagement with said stop means.

9. The saw machine of claim 8, each splitter plate being formed with an elongated slot having an open side oriented to allow said plate to be disengaged from said support member when it occupies a position pivotally displaced from a region of possible contact with said saw.

10. A splitter for use in saw machines having a circular saw, said splitter comprising:

a pair of spaced contacts, each contact having a bearing surface for making contact with opposite sides of a circular saw, a divider member having a plurality of resilient contacts that extend into a region above said spaced contacts and in trailing relation to the rear edge of a saw, each of said spaced contacts being formed on one of a pair of plates, respectively, and means for disconnectable joining said plates to capture the rear edge of the saw, each plate being formed with an elongated slot having an open side that allows said plate to be pivotally engaged with a support member.
