Abstract

854,603. Hasp fastenings. CHENEY & SON Ltd., C. W., TOMKINSON, F. M., CHENEY, H. W., and SHERWOOD, G. M., [representatives of CHENEY, C. W.]. April 22, 1959 [April 22, 1958], No. 12682/58. Class 44. In a spring-loaded hasp fastening of the toggle kind comprising an attachment plate 6, a manually operable lever 13 pivoted by a pin 15 to opposite side lugs 16 thereof, a hasp link 17 pivoted to said lever, a spring permitting said lever to have a snap action into two predetermined positions consisting of the release position and the over-centre fastening position of the hasp link to a catch plate 9 respectively, an integral cross-bar is provided between the lugs of the attachment plate, said cross-bar serving as a tie bar to said lugs for resisting displacement thereof under stresses imposed by the operation of the fastening. As shown the spring 23 is fixed to the attachment plate by an eyelet 27 as disclosed in Specification 852,588 and its end engages a tongue 22 on the lever 13. The crossbar 24 is provided with a slot 25 which receives a pilot dowel 26 depending centrally from the base of the catch plate 9. In a modification a coil spring surrounding the pivot pin 15 is substituted for the blade spring 23. The lever 13 is provided with side flanges 14 which provide a shallow recess at the back of the lever which can accommodate a key operated locking mechanism which co-operates with an upwardly turned lug 32. on the attachment plate 6.
