Abstract

1,225,910. Fastener driving tools. D. HAUBOLD, [trading as DIETER HAUBOLD INDUSTRIELLE NAGELGERATE]. 2 Oct., 1969 [4 Oct., 1968], No. 48436/69. Heading B4C. A pneumatically actuated fastener driving device comprises a driving piston 4 reciprocable in a cylinder 2, a chamber 3 into which air ahead of the piston is forced through apertures 6, 7 when the piston is on a working stroke, and a valve which controls the air pressure in the chamber 3. In operation the piston is forced downwardly by compressed air and the air below the piston is forced into the chamber 3 via apertures 6, 7. When the piston passes aperture 7 compressed air above the piston passes into the chamber via that aperture. When the pressure in chamber 3 overcomes force of spring 17, the valve members 12, 16, 18 and 19 move to the left (see Fig. 3) to close communication between chamber 3 and aperture 7. The force of spring 17 may be adjusted by varying the position of an adjusting screw 14. An elastic buffer 9 is provided within the cylinder.
