Abstract: 1,198,634. Container traffic; jacks. VICTORY TRANSPORT Ltd. 30 Aug., 1967 [29 Dec., 1966], No. 58198/66. Headings B8E and B8J. [Also in Divisions B7 and E2] In a motor-driven vehicle including a chassis 123 and a removable load-supporting platform 125, means for locating the platform 125 on the chassis 123 comprises co-operating male and female parts in the form of an elongated saddle 120 and an elongated member 124 respectively mounted on the chassis 123 and the platform 125 to extend transversely thereof. The saddle 120 has a pair of angles 121 which are received between members 126 to prevent longitudinal displacement between the platform 125 and the chassis 123, transverse movement being prevented by oppositely outwardly inclined locating plates 122 on the saddle 120 co-operating with inclined locating plates 127 on the member 124. In a modification, Fig. 14, the oppositely outwardly inclined locating plates 122 are replaced by oppositely inwardly inclined locating plates 161 co-operating with locating elements (162), Fig. 12 (not shown), replacing the plates 127. Clamping means (not shown), (see Division E2 ) secure the platform 125. Telescopic legs 131 are provided for supporting the platform 125 when removed from the chassis and each has a stay 134. The legs 131 may be compactly stowed as shown on the lefthand-side of Fig. 1. Hydraulic jacks 128 with a spring return may be used to lift the platform 125 off the chassis 123, after clamping means (see Division E2) have been released, to enable the legs 131 to be placed so as to support the platform to allow the jacks 128 to be retracted and the vehicle driven away. Screw jacks may replace the hydraulic jacks 128. Figs. 22, 23 show a screw 167 carried by a thrust bearing 170 and arranged to engage a concave bearing member 129. A threaded sleeve 168 is tightly fitted in the upper race 169 of the bearing 170 and is arranged to be rotated through bevel gears 172, 173 by a drive shaft 171. The drive is carried to another jack (not shown) by sprocket 174 and endless chain 175. Fig. 26 shows a jack in the form of a screw 16 rotatable in a nut 17. In Fig. 30 a screw 40 is arranged in a fixed bearing 41. Cross-bar 48 fixed to square section tube 47 sliding in an outer square section tube 49 is lifted when a square section inner tube 43 engaging a square section head 42 on the screw 40 is rotated. A jacking means suitable for lifting the platform off the chassis, but not attached to the latter, comprises a pair of jacks 105, Figs. 34, 35, and a bar 106 which may be passed through a hollow transversal provided at either end of the platform. Each jack 105 comprises a base plate 107 with a square-section inner sleeve 108 attached. A nut 109 is secured in the upper end of the sleeve 108 and a screw 110 axially movable through the nut 109 has a square-section head 111 to enable it to be rotated. A bearing portion 112 on the screw co-operates with a bearing shoulder 113 in the upper end of a square-section outer sleeve 114. Clamping means 115 comprising plates 116 on the beam 106 and bolts 117 enable the beam to be attached to either end of the jack. In the lower position the beam 106 is shown inverted. The jacks 105 can thus be used to lower the platform in two stages if auxiliary supports are used when changing the beams 106 from the top to the bottom of the jacks 105.
