Abstract

859,584. Drawing-tables. BERGMAN, P. G. Sept. 24, 1959, No. 32516/59. Class 52(3) A drawing board 2 is adjustable vertically with a constant inclination by a parallel motion linkage 4, 8 in which the upper element 4 is approximately L-shaped, thus allowing a table top 7 to lie directly above the supporting shaft 3. In a modification, Fig. 4, linkages 4, 10, 11, 12 form two parallelograms and the counterweight 9 is replaced by torsion springs.
