Abstract

955,721. Stapling machines. BIRMINGHAM SMALL ARMS CO. Ltd. Sept. 19, 1960 [Sept. 17, 1959], No. 31669/59. Heading B4C. An impact device for applying upholstery clips or staples &c, comprises a striker 1 mounted in a guide 2 secured to a housing 3, a spring-urged piston 11 on the striker slidable in a cylinder 12 secured to the housing 3, and a spring urged sleeve 17 slidable between housing 3 and cylinder 12. Air is supplied to the bottom of piston 11 through a spring loaded valve 24 and inlet port 15. The valve is controlled by a lever 25, and clips 6 are supplied to the end 5 of the guide from a magazine 8. In operation valve 24 is actuated to move piston 11 and striker 1 upwardly against spring 22, and a clip 6 is pushed into end 5 of guide 2. End 26 of the piston engages flange 18 of sleeve 17, and moves the latter against spring 19 until the sleeve clears outlet ports 16. The air in the cylinder passes through an opening 21 in the housing thus reducing the cylinder pressure, and spring 22 moves striker 1 to drive the clip into the article. Due to the movement of lever 25 towards handle 4 to open valve 24, a pin 27 connected to the lever engages a collar 28 on the sleeve and restrains it against downward movement, and exhaust ports 16 remain open thus producing a single impact for each operation of trigger 25. Specification 933,761 is referred to.
