[Class 69 (i)] [Also in Groups XXXII and XXI] Means for converting a vehicle into a liquidcarrier for fire-extinguishing, decontaminating, &c. purposes comprise a collapsable structure adapted to be erected on the vehicle floor to support or form a collapsable liquid-container connected with a pump. The sides of the vehicle may assist in supporting the walls of the container in part and further foldable or collapsable members be provided to complete the support. In the construction shown in Figs. 5, 7 the recess 14 carries a tray 38 normally closed by sections 11, 12 which are held erect in the operative position by struts 46 and the liquid container is formed by a collapsable structure comprising substantially rigid end plates 49 and side plates 50, e.g. of metal, hinged to the tray 38 by strips 51 of canvas &c. To permit the plates 49, 50 to fold flat into the tray, the ends of the side plates 50 are inclined and connected by substantially triangular-shaped canvas &c. pieces 52 to the end plates which are bolted in the upright position to the sections 11, 12 or are slidably secured thereto so as to be raised and lowered therewith. The side plates 50 are held erect by vertical stanchions engaging slots in the floor battens and reinforced bv inclined struts 58. The container is connected through a strainer 61, hose 60, valve 62, and conduit 63 fitted with a hose coupling, to a pump 64 the delivery side of which is connected to twin pipes 65 fitted with hose couplings. Instead of drawing liquid from the container, the conduit 63 may be connected to a mains hydrant or external reservoir, the valve 62 being closed. Fig. 9 shows a further construction in which the container has rigid foldable ends 11, 12 and flexible sides 74 reinforced by one or more bars 77, oppositely-disposed bars being connected by ties 78. When the ends are folded bars 80 thereon engage the base 81 to form pockets for stowing the flexible sides. The sides are sealed to the ends to a level a little above the highest liquid level and in order to prevent splashing, flexible flaps 73 on the upper edges of the sides are adapted to be secured to the end sections 11, 12 by bars 75. Mechanical, hydraulic, manual, or power means may be provided for raising the floor sections. As shown the sections 11, 12 are connected by cables 88 to a manually-operable winding drum 89. In another construction the container is composed of rigid foldable side and end members provided with co-operating sealing means comprising e.g. tubes or rods fitting into opposed grooves in the adjacent parts, clamping means maintaining the sealed connections. When a separate flexible container is used, it may be folded or rolled up to lie below the vehicle floor or stowed elsewhere in the vehicle. For example, a container which collapses concertina or bellows-fashion may be housed under the vehicle roof and lowered by cables &c. into position.
