1, 243, 711. Trysquares. QUENOT & CIE S. A. R. L. Jan. 2, 1969 [April 4, 1968], No.386/69. Heading G1X. A try square comprises a stock 1 made from two metallic channel section members 2 joined back to back and formed with projections 4 which space the members 2, a metallic blade 7 fitted in the space between the members 2, the stock 1 being embedded in a coating 11 of synthetic plastics material. The projections 4 of the two members 2 are preferably welded together and the blade 7 is provided with holes 8 in which tabs bent out of the members 2 engage to locate the blade, the tabs being additionally secured by welding. The synethetic coating meterial may be coloured or transparent and preferably extends through openings 15 in the members 2 to increase the rigidity of the coating 11. The edge 12 of the coating is disposed at 90 degrees to the blade 7, and in a modification of the invention the edges of the channel section members may be bent so that they extend to the surface of the coating 11 at the four corners of a section through the stock 1.

L. 1969年1月2日[1968年4月4日],编号386/69。标题G1X。三角架包括由两个金属通道部分构件2背靠背连接并形成有间隔构件2的凸起4的砧木1,安装在构件2之间的空间中的金属刀片7,砧木1嵌入在一个合成塑料材料涂层11。两个构件2的突出部4优选地焊接在一起,并且叶片7设置有孔8,从构件2中弯曲出来的突片接合在孔8中以定位叶片,突片另外通过焊接固定。合成涂层材料可以是有色的或透明的,并且优选地延伸穿过构件2中的开口15以增加涂层11的刚度。涂层的边缘12与刀片7成90度设置,并且是对涂层7的修改。在本发明中,通道部段构件的边缘可以弯曲,以使得它们在穿过坯料1的部分的四个角处延伸至涂层11的表面。
