Abstract
Abstract An adjustable depth groove cutter and support therefor for mounting on the spindle of a shaping machine. The cutter head includes a base plate having upstanding pivot pins formed thereon. A cutter having a plurality of groove cutting teeth is mounted on each pivot pin for eccentric adjustment with respect to the axis of rotation of the cutter head. The cutting tooth arrangement on the cutting blades is such that each tooth removes a small portion of the total cut so that the cutting work is divided among all of the teeth. As the cutter blades are adjusted eccentrically outwardly the depth of the cut is increased.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
An adjustable depth groove cutter for mounting on a rotatable spindle having a spindle nut comprising a generally cylindrical base plate having an axial bore extending therethrough for engagement over said spindle, a pair of upstanding generally cylindrical pins integrally formed on said base plate on opposite sides of said axial bore, a pair of cutter blades pivotally mounted on said pins, a washer having an axial bore extending therethrough for engagement over said spindle with said washer having a pair of diametrically opposed bores for engagement over the pins on said base plate, said washer clamping said cutter blades under pressure of the spindle nut, said spindle having a diameter substantially less than the diameter of the bores in said base plate and said washer and a sleeve mounted on said spindle to space said base plate and said washer axially thereon.
Claim 2
Dependent Claim
143 words
An adjustable depth groove cutter for mounting on a rotatable spindle having a spindle nut comprising a generally cylindrical base plate having an axial bore extending therethrough for engagement over said spindle, a pair of upstanding generally cylindrical pins integrally formed on said base plate on opposite sides of said axial bore, a pair of cutter blades pivotally mounted on said pins, a washer having an axial bore extending therethrough for engagement over said spindle with said washer having a pair of diametrically opposed bores for engagement over the pins on said base plate, said washer clamping said cutter blades under pressure of the spindle nut, said spindle having a diameter substantially less than the diameter of the bores in said base plate and said washer and a sleeve mounted on said spindle to space said base plate and said washer axially thereon.
Claim 3
Dependent Claim
160 words
An adjustable depth groove cutter for mounting on a rotatable spindle having a spindle nut comprising a generally cylindrical base plate having an axial bore extending therethrough for engagement over said spindle, a pair of upstanding generally cylindrical pins integrally formed on said base plate on opposite sides of said axial bore, a pair of cutter blades pivotally mounted on said pins, a washer having an axial bore extending therethrough for engagement over said spindle with said washer having a pair of diametrically opposed bores for engagement over the pins on said base plate, said washer clamping said cutter blades under pressure of the spindle nut, said cutter blades being provided with a plurality of teeth incorporated into a serrated circular arch so that when the blades are pivoted outwards eccentricity is obtained, the tooth closer to the pivot takes a greater amount of the cutting job and each succeeding tooth takes a gradually decreasing amount of the cutting job.
Claim 4
Dependent Claim
160 words
An adjustable depth groove cutter for mounting on a rotatable spindle having a spindle nut comprising a generally cylindrical base plate having an axial bore extending therethrough for engagement over said spindle, a pair of upstanding generally cylindrical pins integrally formed on said base plate on opposite sides of said axial bore, a pair of cutter blades pivotally mounted on said pins, a washer having an axial bore extending therethrough for engagement over said spindle with said washer having a pair of diametrically opposed bores for engagement over the pins on said base plate, said washer clamping said cutter blades under pressure of the spindle nut, said cutter blades being provided with a plurality of teeth incorporated into a serrated circular arch so that when the blades are pivoted outwards eccentricity is obtained, the tooth closer to the pivot takes a greater amount of the cutting job and each succeeding tooth takes a gradually decreasing amount of the cutting job.
Claim 5
Dependent Claim
28 words
A device as claimed in claim 2 wherein said teeth have a width substantially greater than the thickness of said cutter blade to provide a wider groove cut.
