Title: Improvements in apparatus for driving securing means such as staples and the like
IPC: B25C1/04
Filed: 1962-02-06
Abstract: 979,463. Stapling-machines. D. HAUBOLD. Feb. 6, 1962 [Feb. 11, 1961], No. 4563/62. Heading B4C. Pneumatic hand-tool for driving staples &c. comprises a piston 18 driven by compressedair and operating a driver 20, and a cylinder 17 to which the compressed-air is also fed to return the piston. The driver 20, members 22 carrying a buffer plate 23, and spacing tubes 21 are mounted on a pin 19 in the piston, which is held in the raised position by a magnet 32 or a mechanical lock. Operation of a valve 15 by a lever 14 connects the air supply chamber 13 with a duct 16 opening into the top of the cylinder and produces a working stroke of the piston. During this stroke, air beneath the piston is exhausted through the driver-passages 25, 28, which are sealed at the end of the stroke by contact between the buffer 23 and a rubber &c pad 27. The driver 20 may be slotted to facilitate the escape of air. A hole 30 in the piston allows compressed-air to pass to the cylinder-space beneath the piston, until the supply is interrupted by release of the lever 14. The valve 15 then connects the cylinder-space above the piston to exhaust passage 29, allowing the compressed-air beneath the piston to raise it against the magnet 32. There is a magazine 26 for the staples, and a non-return valve may be fitted to the underside of the hole 30. In a modification, Fig. 2, a tube 34 acts as the buffer or supports a buffer 37 for a solid piston 33, and air is fed to the cylinderspace beneath the piston, when this is at the bottom of its stroke, along a channel 36 in the cylinder-wall. The piston 33 may be made of light metal or plastics and include a disc of magnetic material. Instead of exhausting through the driver-passage 25 the lower cylinder-space, this may be exhausted through a side opening 41, Fig. 3, controlled by a disc 42 carrying seals 43, 48 and held in the raised position by a spring-pressed ball 45 engaging a groove 46 in the cylinder-wall. At the end of down-stroke, the piston 33 displaces the disc 42, closing the exhaust port 41. As before, a channel 36 leads compressed-air beneath the piston, which is again returned by releasing the lever 14. Towards the end of the return stroke, a shoulder, Fig. 5 (not shown), on the driver engages the underside of the disc, returning it to its raised position of Fig. 3. In a further construction having a side channel 36, Fig. 6, the driver and exhaust passage 25, 55 is sealed at the end of the down-stroke by an enlargement 54 on the driver 20. Instead of a side channel 36, the piston may have a larger clearance in the cylinder.
