    • 1402090 Mobile jib cranes; load handling SHAW TREW & SMITH Ltd and D G SHAW 4 Oct 1972 [6 July 1971] 31551/71 Headings B8B, B8H [Also in Divison B7] A mobile, telescopic jib crane comprises a chassis 1 with forward and rearward portions 2, 3, a rearwardly extending beam 30 from the forward portion 2 slidably engaging the rearward portion 3. The beam 30 is mounted on a swivel 35 on the forward portion 2 to permit relative oscillation of the two portions 2, 3 about the axis of the beam 30 when travelling over rough ground. The telescopic jib 10 is pivotally connected by a tie linkage 6 to a carriage 7 slidable on the rear portion 3, a pair of rams 8 being pivoted at 38 on the carriage 7 and at 9 on the jib 10. Mutually inclined links 12, 13 are also pivoted at 9 and, respectively, at 32, 33 on the forward and rear portions 2, 3. Further links 14 are pivoted on the carriage 7 at 15 and at 34 on the links 12, 13. When the rams 8 are extended the jib 10 is raised and the wheelbase reduced the front wheels 4 taking up an extreme position indicated at 4a. Conversely when the jib 10 is lowered the wheelbase extends to increase the stability of the load. Fig. 3, shows the steering arrangement for the front wheels 4. A lever 41 is pivoted at 42 and at one end has a pair of rams 40 pivoted at 43, their other ends being pivoted to the forward chassis portion 2. A further pair of rams 45 is pivoted to the lever 42 at 44 and at 46 to king pin mountings 48 on the front axle beam 47. Operation of the rams 40 effects steering movement of the wheels 4, the rams 45 being inoperative and acting as a track rod. With the rams 40 inoperative the wheels 4 may be inturned, as to 4b, by extending the rams 45, to permit a slowing operation of the crane. A fork-lift unit (20), Fig. 5 (not shown), may be fitted to the forward chassis portion 2 and may have a tilting mast (24) and folding forks (22). The jib 10 and fork-lift unit (20) may be used separately or jointly.

The buckets of an endless bucket conveyer comprise an L-section plate 1 pivotally supported about its forward end in the direction of travel and a pair of side plates 5 mounted on the inner links of a pair of spaced chains 2. The spaced chains 2 have common pivot pins 4 extending across the conveyer and acting to pivotally support the forward end of the plate 1 by means of lugs 1d attached thereto. The trailing edge of the plates 1 have a lip 1e which rests upon the following pivot pin 4. The buckets are discharged by a pair of hexagonal wheels 7 rotatable with end sprockets 3 and contacting the underside of the plates 1, as they pass around the sprockets, to move them outwardly about pivot pin 4 relative to the side plates 5. The plates are prevented from excessive outward movement under gravity during the return run of the conveyer by lugs 9 attached to the links of the chains 2.

A side discharge mechanism for endless belt conveyers comprises a thrust member 7 pivoted about its lower end 9 and adapted to be raised against the underside of the operative run of the conveyer 1 to impart an inverted V cross-section to the belt for discharge to both sides thereof. The upper edge of the thrust member 7 carries a central roller 5 of larger diameter at its centre than at its ends and cylindrical rollers 6 mutually inclined on both sides thereof. The thrust member is moved from its inoperative position 7a to its operative position by an hydraulic ram 10 pivoted at 12 and attached'to the thrust member 7 by brackets 11 on either side of an opening 13. A framework 3 supports the ram 10, the thrust member 7, conventional idler rollers 2, the return run of the conveyer 1b and has downwardly inclined lateral guide members 15 to deflect discharged material clear of the conveyer assembly. In an alternative embodiment (not shown) the thrust means may move in the vertical direction only.

    • 1,105,602. Endless conveyers. SHAW, TREW & SMITH Ltd., and D. G. SHAW. 18 June, 1965 [19 March, 1964], No. 11585/64. Heading B8A. An endless conveyer has a conveying surface 1 provided by a pair of series of plates 2, 2 each of which is pivoted at 5 to a roller chain 4. The plates 2, 2 of each series have a lap joint 3, to provide continuity of the conveying surface in the operative run. As shown in full lines the plates 2, 2 are mutually inclined in a trough-like manner, so as to be able to convey material such as coal, the gap between the plates 2, 2 being closed by a spine 11. The roller chain 4 runs on a platform 15 which may be raised by hydraulic means (not shown). When the platform 15 is raised the two series of plates 2, 2 are mutually inclined in an outwardly downward direction so that side discharge of the conveyed material can take place as shown in dotted lines. Discharge may be obtained from one side only by having only one series of pivoted plates 2, the other series being fixed. Alternatively or additionally tracks 14 may be vertically operable either together or independently. All the plates 2 may be pivoted about a common central longitudinal axis, e.g. in a hinge-like manner, in which case a spine 11 is not required. In a further arrangement a single series of pivoted plates 2 may co-operate in the operative run with and travel relative to a fixed plate or like surface mutually inclined to the single series of plates 2 in the conveying condition (not shown).
