Abstract
Abstract A mounting-device for a pin-router for use on a conventional radial table saw which attaches in the same manner as a saw blade and uses the saw's elevation mechanism. The device has a housing with an opening for receiving the saw motor shaft. Mounting brackets on the housing attach the housing to the horizontal beam of the radial saw to prevent pivotal movement of the housing about the saw motor shaft. An adjustable support yoke secures the pin-router in the housing so that the pin-router longitudinal axis is normal to the plane of the saw table.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A pin-router mounting device for use with a radial table saw of the type having a flat table, a vertical post fixed to one edge of said table, a vertically adjustable horizontal beam extending at a right angle to said post over said table and being movably secured to said post for selective vertical movement, and a radial saw motor secured to said beam and having a saw motor shaft, comprising: a housing having an opening adapted to receive said radial saw motor shaft; locking-means for engaging said housing on said motor shaft; mounting means on said housing for attachment to said horizontal beam to prevent pivotal movement of said housing about said motor shaft; and adjustable support means for removably securing said pin-router in said housing so that said pin-router longitudinal axis is normal to the plane of said table.
Claim 2
Dependent Claim
141 words
A pin-router mounting device for use with a radial table saw of the type having a flat table, a vertical post fixed to one edge of said table, a vertically adjustable horizontal beam extending at a right angle to said post over said table and being movably secured to said post for selective vertical movement, and a radial saw motor secured to said beam and having a saw motor shaft, comprising: a housing having an opening adapted to receive said radial saw motor shaft; locking-means for engaging said housing on said motor shaft; mounting means on said housing for attachment to said horizontal beam to prevent pivotal movement of said housing about said motor shaft; and adjustable support means for removably securing said pin-router in said housing so that said pin-router longitudinal axis is normal to the plane of said table.
Claim 3
Dependent Claim
143 words
A pin-router mounting device for use with a radial table saw of the type having a flat table, a vertical post fixed to one edge of said table, a vertically adjustable horizontal beam extending at a right angle to said post over said table and being movably secured to said post for selective vertical movement, and a radial saw motor secured to said beam and having a saw motor shaft, comprising: a housing having an opening adapted to receive said radial saw motor shaft; locking means for engaging said housing on said motor shaft; mounting brackets on said housing for attachment to said horizontal beam to prevent pivotal movement of said housing about said motor shaft; and an adjustable support yoke for removably securing said pin-router in said housing so that said pin-router longitudinal axis is normal to the plane of said table.
