Abstract

1,173,820. Sharpening machine cutters in situ. E. M. ELEN. 13 May, 1968 [30 May, 1967], No. 24939/67. Heading B3D. [Also in Division D1] A knife blade 12 rotating about a horizontal axis 12A for tearing up rags is sharpened by a pair of sharpening stones 27 which are mounted on a common cradle 24 and normally biased by spring 30 away from the blade but which are moved into contact with the blade by operation of the handle 14 which is connected to the cradle through a link 18 and a spring 31. The handle rotates about shaft 15 and rotates with it the link 18. The Cradle is rotatably mounted about a horizontal axis 24A on a curved arm 22 which is freely rotatable about shaft 15. The stones are double bevel ground for reversal, and the grinding edges 28 of the stones contact opposite sides of the blade 12. When handle 14 is depressed in direction 21 spring 31 extends and pulls cradle 24 downwards by rotating arm 22 against face of spring 30 until stones 27 engage blade 22.
