Abstract

792,697. Hook fastenings. CLIPPER MANUFACTURING CO., Ltd. (Clipper Manufacturing Co.). Dec. 30, 1955, No. 37470/55. Class 44 [Also in Groups X and XXXI] A platform 40 of a concrete cutting machine is pivoted at 46 to a wheeled support 10, a spring 76 urging the platform in an anti-clockwise direction and the platform and support being rigidly interconnectable by latch means 80. The means comprises a link 82 pivoted at 84 to the platform and carrying a hook 86 engageable with the support 10. The link 82 is urged in a clockwise direction by a spring 88, and the hook 86 engages the support on depression of the platform by a treadle 78. The hook can be disengaged by a pedal 90 pivoted at 94 to the link and carrying arms 92 adapted to bear on the support. In a modification, Figs. 6 and 7 (not shown), a pivoted and spring urged hook member is carried by the support and engages with the platform when the latter is depressed by a pedal, the member being released by a foot plate thereon. U.S.A. Specification 2,736,544 is referred to.
