Abstract
Abstract An attachment is mounted on the support of a dial indicator having a reciprocable actuating stem, and a measuring blade is pivotably mounted on a shaft in the attachment. An actuating arm is mounted on the shaft and has an inwardly curved portion which contacts the stem of the dial indicator so as to actuate the dial indicator in a linear response with respect to the angle indicated by the measuring blade.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
In an angle measuring attachment for a dial indicator having a reciprocable actuating stem, the combination including a mounting bracket rotatably adjustable relative to the indicator about the axis of said stem and having a bifurcated extension substantially parallel to said stem and spaced therefrom, a shaft pivotally mounted in said bifurcated extension, a measuring blade secured on said shaft by set screw means outwardly of said extension, an actuating arm secured by set screw means on said shaft between said bifurcations, and means on said actuating arm for actuating said stem linearly in response to a pivotal movement of said measuring blade when measuring an angle.
Claim 2
Dependent Claim
107 words
In an angle measuring attachment for a dial indicator having a reciprocable actuating stem, the combination including a mounting bracket rotatably adjustable relative to the indicator about the axis of said stem and having a bifurcated extension substantially parallel to said stem and spaced therefrom, a shaft pivotally mounted in said bifurcated extension, a measuring blade secured on said shaft by set screw means outwardly of said extension, an actuating arm secured by set screw means on said shaft between said bifurcations, and means on said actuating arm for actuating said stem linearly in response to a pivotal movement of said measuring blade when measuring an angle.
Claim 3
Dependent Claim
59 words
In an angle measuring attachment as claimed in claim 1, said linearly actuating means comprising an inwardly curved portion having a rounded end on the outer end of said actuating arm to contact the end of said actuating stem so that said arm and said actuating stem are movable in response to the angular position of said measuring blade.
Claim 4
Dependent Claim
15 words
