Abstract

1369935 Luffing boom apparatus CLARK EQUIPMENT CO 27 June 1972 29961/72 Heading B8H [Also in Division E1] A device 10 for attaching an implement 16 to a pair of spaced actuating arms comprises an elongate member 20 adapted to engage the implement, a pair of brackets 21, secured to the member 20 and extending transversely thereto, for mounting the arms, and releasable means spaced from the member 20 for securing the brackets to the implement. The elongate member 20 wedges under an overhang 18 on the implement and the brackets lie on a shelf 19 on the implement, to which they are secured by the engagement of hooks 30 with holes 31, into which they are urged by springs 33 acting on lever arm 40. Alternatively, Figs. 5, 6 (not shown), the hooks may be urged into position by the engagement of rollers (53) with bars (54). The mounting of the hooks may include eccentric bushings (55), Fig. 7 (not shown), to adjust the position of their pivot axes. Instead of hooks 30 there may be axially slidable wedge members (81), Fig. 8 (not shown), urged into the holes 31 by springs (84) and raised by lever (90). Or, Figs. 11, 12 (not shown), axially slidable wedge members (110) may be controlled by separate over-centre linkages (112). The device is secured at 24, 25 to the loading arms (14) and tilt cylinders (15) of a front end loader (11), Fig. 1 (not shown), and the implement may be, for example, a bucket, snow plough, sweeper, log grapple or fork lift.
