Pocket Caliper Gauge. 



This is a light and convenient tool, graduated on one 

 side to 64ths and on the other to lOOths of an inch, just the 

 instrument for taking the calibers of rods, hooks, lines, etc. 

 The thumb-screw is counter-bored to receive a spiral spring 

 which bears on the nut and washer, thus creating a moder- 



ate friction, which, when the nut is loosened, facilitates 

 the setting of the gauge to the desired measurement. It is 

 finished in the best manner, and opens two inches.
