Abstract

967,129. Sawing. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 20, 1962 [Dec. 20, 1961], No. 48098/62. Heading B5L. [Also in Division E2] A device for locking and tensioning a saw blade 1 on the frame of a sawing machine of the reciprocating type comprises two tensioning systems, each co-operating with one of the ends of a saw blade and consisting of a base 2 adapted to be connected to the frame, support means 3 movable with respect to the base in order to hold the blade in one plane, pivoting means 5 for locking the blade on the support means, and a mechanical connection 8 between the support means and the locking means, one of the systems being a driving system and comprising means 11, 12, 14 for successively controlling the pivoting movements of the locking means and the displacements of the support means with respect to the base. The pivoting means on the driving system consists of an L-shaped lever 5 having two arms, one of which is connected by a pin 6 to a fork 7 and the other of which is connected by a pin 15 to a slide 11 which is movable relative to the base 2 and support 3 by a screw-and-nut mechanism 12, 14, the lever also being connected to the support 3 by a connecting-rod 8 and pins 9, 10. The support 3 has a projection 4 for engaging a hole in one end of the blade, the hole in the other end of the blade being engaged by a projection 4a on a slide 3a movable on a base 2a. A similar lever 5a and fork 7a is provided to retain the blade on the support 2a. To release the blade, the nut 12 is rotated to axially move the screw and slide 11 so that the lever 5 is pivoted to move the fork 7 from locking engagement with the blade 1 and projection 4, the slide moving until it abuts the support 3. Further rotation of the nut 12 moves the support 3 and the blade to cause the support 3a to slide relative to the base 2a and the lever 5a to pivot and remove the fork 7a from looking engagement with the blade and projection 4a. The blade can thus be removed and replaced, the new blade being tensioned by rotating the nut in the opposite direction. In an alternative embodiment, the nut 12 is replaced by bevel gearing and a sleeve nut. The device may be used in a machine which is in a place inaccessible to human operation, e.g. in a radio-active atmosphere, the nut or bevel gearing being operated by remote handling devices. If the saw blade breaks, the system 2a is operated by interposing a rod between parts on the supports 3, 3a so that movement of the support 3 causes movement of the support 3a.
