Abstract

912,242. Blasting. MACMILLAN, W. R. July 1, 1959 [April 3, 1958], No. 10774/58. Class 60. Means for retaining blades in radial grooves of side plates of shot blast impeller wheels comprises a pair of locking blocks which are adapted to lie radially along the back of the blade and are supported by resilient means from a block spacing the side plates, the blade being provided with lugs adapted to displace temporarily the locking blocks during insertion into the wheel and thereafter to engage the locking blocks to retain the blade. Locking blocks 10, 11 are mounted on legs 14, 15 of a wire spring 12 secured to a spacer block 13, and have tapers 16, 17. During insertion of the blade 6, which may be tapered as described in Specification 912,241, wedge-shaped lugs 7, 8 on the blade force the blocks 10, 11 towards each other, and when the blade is in position, the blocks 10, 11 engage behind the lugs 7, 8. The blade is removed by an extractor tool comprising a member having two wedgeshaped ends to displace the locking blocks and also comprising a claw member which passes down between the locking blocks to engage a recess in the back of the inner end of the blade.
