Abstract: 454,195. Scavengers' vehicles ; separating. CAMBESSEDES, J. E. F., 18, Boulevard Arago, Paris. Dec. 5, 1935, No. 33800. Addition to 437,154. [Class 108 (i)] [See also Group II] In the apparatus described in the parent Specification for sorting household rubbish and depositing it into compartments in the vehicle body, means are provided for continuous sorting, improved devices are provided for gripping and discharging soft articles and for recovering waste fabric and papers and collector receptacles are provided in the body oompartments. The rubbish is raised by means of balanced buckets 2, Fig. 4, interconnected by a chain 3 and driven through a sprocket 10 from the main engine shaft 55, Fig. 1, and discharged into a shoot 11 on to a belt 12 having at one end a rotary magnetic separator 13 whereby magnetic products are separated and moved in the direction of the arrows 14 into the first compartment 15. The remainder falls on. to a screen comprising parallel bars 16 and shaken by adjustable eccentrics 17 whereby small hard material such as stones are sorted out and drop on to a further screen 18. The finer parts fall directly through into the container 21, the next larger parts into the container 22 and the large articles which have rolled from one screen to the other are discharged into container 23. The unsorted material then proceeds to the elevator 29 comprising parallel chains 31, transverse bars 32, Fig. 5, having secured to them needles 34 passing through apertures in plates 35 also secured to the bars 32, slots being formed in the plates 35 so that they strip the needles and carry the material into position to be pierced by prongs 37 carried by chains 39. The material such as woody matters and very soft articles which are not pierced by the prongs 37 drop into a tiltable container 41, while the pierced material, such as paper, rags, vegetables, are carried by the chains 39 rearwardly and are acted upon successively by a soft oscillating brush 42, a stiffer oscillating brush 43, and a fixed comb 44 whereby the materials are discharged into the container 41 and into transverse channels 45, 49 respectively, the transverse channels discharging by means of chains 46 into tiltable containers disposed on either side of the body. The chains 39 are mounted resiliently by means of levers 50 and a spring 53 while the plates 35 on the elevator 29 are also resilient. Fig. 3 shows the arrangement of mounting the tiltable containers 21 which are provided with rollers 27 running on rails 28 and are also carried by arms 24 pivoted to the body whereby the filled containers can be withdrawn from the body and turned upside down for emptying purposes. In a modification, the elevator comprises chains with plates 92 having teeth 93, Fig. 11, and with buckets 90 also' provided with teeth. Material shot on to the screen 95 is partly picked up by the teeth, while the material which has passed through the screen 95 is picked up by the buckets 90. The soft articles are detached by the comb 98 and pass down the inclined plane into compartment 101. The hard articles in the buckets are discharged by the buckets opening as shown and their contents discharged into compartment 102 or into compartment 105 by passing along the grid 103 which is reciprocated by a cam 110 on the shaft 109 driving the sorting devices. The elevator is carried by the rear door pivoted at 112 which when raised permits the screen 103 and plane 99 to be lowered to allow the body to be emptied by tilting, the successive compartments being emptied as their divisions or partitions are removed or lowered.
