Abstract

335,919. Penkala Tvornice D. D. Jan. 31, 1929, [Convention date]. Void [Published under Sect. 91 of the Acts]. Addition to 335,918. Setsquares.-Two of the arms 14, 15 of a setsquare &c. are connected to the third arm 16 by pivots 30, 31 and are connected together at their outer ends by a press-fastening &c. 29 so that they can be disconnected from each other and then turned into alignment with the arm 16 so that the whole forms a ruler. In Fig. 6 all the arms are slotted to enable a square having any desired angles to be formed.
