Abstract

1,226,837. Stapling machines. D. HAUBOLD [trading as DIETER HAUBOLD INDUSTRIELLE NAGELGERATE]. 15 July, 1968 [13 July, 1967], No. 33657/68. Heading B4C A pneumatic stapling device including a manually operable control valve for connecting the space above a driving piston reciprocable in a cylinder with a source of compressed air or with the atmosphere comprises an auxiliary valve which can be adjusted to condition the device for "auto-fire" or "single fire". Initially air in a reservoir 3 passes to the upper surface of a valve body 14 and the lower surface of a slide valve 27 via an opening 19 in a housing 11 and a bore 15 in a stem 16 and chamber 34, respectively to maintain the valve body and slide valve in the position shown. Depression of button 18 opens the space 34 to atmosphere via a bore 39, and air pressure forces the valve body downwardly and away from seat 21 to permit air to flow via bore 5 to the cylinder to effect driving of the piston. The cylinder has apertures (46) (Fig. 1, not shown) such that when the piston has completed its working stroke compressed air will flow into a chamber 45 and will act on a valve piston 49 which is biased by a compression spring 51. When used for "autofire" a screw-threaded cap 56 will be so adjusted as to permit air to flow via bore 31 into the space between the valve body and slide valve, and return the valve body to the position shown. Sealing ring 24 is moved away from seat 23 to allow the space above the drive piston to communicate with atmosphere. The driving piston is returned to its initial position by compressed air in the chamber 45 acting on the under-side of the piston via ports (47), the pressure of air in the chamber 45 drops the auxiliary valve piston 49 returns to the position shown to open the bore 31 to atmosphere via bore 55, and the valve body is again moved downwardly to recommence the driving stroke of the driving piston. Adjustment of a screw-threaded nut 56 will vary the speed of operation of the device during "auto-fire". For "single-fire" the cap 56 is adjusted so that the compressed air pressure does not overcome the force of the spring 51 acting on the auxiliary valve piston.
