Abstract

8840. Spaeth, M. April 26. Compasses, drawing.-In compasses for drawing spirals of different pitches, the leg a, which is prevented fiom rotating, screws into the nut m, which is pivoted at g to the working leg i. The end of the screw c is kept in contact with the lever d, and thus rotation of the leg i about the leg a results in the alteration of radius of the curve described. The length of the leg i is automatically adjusted as shown. In order that screws of different pitches may be used, the leg a is screwed into a sleeve n, which fits loosely in the socket m and is prevented from rotating by the pin o. The sleeve and leg can thus be removed, and another leg, having a screw oi different pitch, can be substituted.
