6441 T Clinograph. 



The clinograph is a very useful instrument when a number of lines are required at an angle to the base line 

 other than are found on an ordinary set square. The arc attached to the movable arm is divided to degrees, and 

 a clamping screw tightens to an auxiliary strip of metal, which presses on arc and holds firmly when set. 



Two working edges are provided so that angles and opposite angles of any degree are accurately obtained. 



Made in dyed hardwood, with two celluloid edges and German silver arc, engine divided.
