600,143. Window catches. WALKER, J. H. (trading as PETFORD & POUNTNEY), and JONES, G. Sept. 28, 1945, No. 25207. [Class 44] A window fastener comprises a channelled bracket 1 carrying a spring 2 and a pivot 4 for a lever 3 and a catch member 5 having an overhanging portion 5b and a recess 5a, Fig. 3. The lever 3 has a nose 3a which, engaging the spring, maintains the lever in either of the two alternative positions. An oversized bearing hole 3c allows the lever some lateral displacement. The catch is fastened by depressing the lever 3 so that it slides past the rounded head 5c of the catch 5 and is engaged in the recess 5a. In unfastening, the lever is lifted clear of the recess 5a, displaced sideways to clear the hook 5b and lifted into the upright position.
