514,296. Loading 'refuse vehicles. WALKER BROS. (WIGAN). Ltd., WALKER. D., and ELFORD, E. J. March 30, 1938, Nos. 26543/39 and 26544/39. Divided out of 513,782. [Class 78 (iv)] [Also in Group XXXII] A vehicle for the collection and transport of refuse has a closed body with a loading opening in the roof, power-driven lifting-means for refuse containers, pivots attached to the lifting- means and attachable to the containers, and levers connected to the pivots coacting with stops on the vehicle to invert the container towards the end of its lifting movement so that its mouth projects into the opening in the roof. In the illustrated form the container is clamped in the two-part .securing ring 49 mounted on trunnions and carrying rollers 56 engaging guide rails 47; being also fitted with eyes for the attachment of cables 61 running to a winch 66. As the container is hauled up the guides the projecting arms 59 engage stops 78 and rotate it into the inverted dotted-line position 44. During the inversion a certain amount of vertical play between the securing ring and the container fittings allows the container to bump against the ring and dislodge sticking contents. The contents are discharged through a hole in the roof into the space 38 in the closed interior of the vehicle; the latter being fitted with a movable floor and wall for packing and discharging the load as. described in Specification 513,782. The charging hole is closed normally by a sliding door 80 connected by cords 86 to a spring roller 87, Fig. 15, at one end and also connected similarly to a spring roller 85 at the other end. Lugs 81 on the main hauling cables 61 engage the door and open it as the container moves upwards. Also laterally-projecting lugs 95, Figs. 1 and 2, on the hinged lid of the container, are arrested by ramps 96 so that the lid remains behind and is opened as the body completes the tipping movement. At the same time the continued movement of the body slides the lid into the position shown at 97. In some cases the lugs 95 may be detachable and fitted when the container is ready to be hoisted. A ring of bristles 45 prevents escape of dust during the transfer. The charging hole may be formed in a detachable panel which can be removed bodily and replaced by, others carrying doors of different shape for dealing with different .shapes of containers. A flexible barrier 98, Fig. 1, prevents entry of dust into the closed mechanism-containing compartment into which the door 80 slides. In dealing with small containers, a large guided skip receives the contents of a series of such containers and is hauled up the guideways to deliver to the vehicle when filled. The skip may be provided with movable screen's and hoods to confine dust during the tipping operation. Large containers may be transported to and from the vehicle by a trolley which is normally stowed under the vehicle: This trolley 121 has a platform 122 raised by links 123 when the handle 125 is forced downwards. Some containers may have detachable hinged lids which are applied to them during transport.and unloading only. The hinge 100 in such cases is fixed to the lid and is attached adjustably to the container by screw mechanism which permits alignment of the pointers 107, 108 to position the lid correctly for engagement with the ramps 96.
