Abstract

957,193. Securing screening elements. F. PARKER Ltd. Jan. 26, 1962 [Oct. 26, 1960], No. 36762/60. Heading B2H. [Also in Division E2] In a single or multi-deck screening apparatus at least one screening unit 4, Fig. 2, is adjustably secured to a frame 3 by a fastening element 8 in the form of a talon, at least one arm being secured to each talon to project outwardly through the frame, the arm or arms being rockable in fixed lugs 15, and held in an adjusted angular position by use of a wedge 17. Each screening unit 4, e.g. a wire mesh screen, is supported on fixed brackets 6 fitted with wear beading 7, and along its edges the element is bent to form a hook 11 protected by reinforcement 12. Each talon 8 is also bent at its lower end 10 to engage with the hook 11. Each arm 9 has an enlarged head 16 to engage the associated wedge 17, which has an inclined lower face engaging with an inclined upper face on a member 19 secured to a fixed bracket 14, Fig.3 (not shown). To tighten the unit 4 the head 16 may be raised by use of a tommy bar 23 inserted into a recess 22 and the wedge 17 is moved to prevent return movement of the head, the wedge being locked in position by a peg (not shown) fitted in one of several holes in the member 19. The wedge 17 also has an inclined side face 24 so that it can be used when turned on its side. The range of adjustment covered by the face 24 is complementary to that covered by the normal bottom face. In an alternative arrangement, Fig. 4, each head 16<SP>1</SP> is fitted with a pawl 25 engaging with a ratchet block 26 carried by the corresponding bracket 14. On raising the head 16<SP>1</SP> with a tommy bar the ratchet automatically locks the arm 9 against return movement. The apparatus on the screening elements may be vibrated, agitated, oscillated, or rotated.
