687,564. Charging sealed refuse vehicles; raising and tipping bins. REY, F. Oct. 1, 1948. [Oct. 1, 1947 ; Sept. 27, 1948] Nos. 25598/48 and 25599/48. Class 78 (iv). The loading aperture of a refuse vehicle is sealed by a hood comprising sector-shaped parts 15, 34 pivoted at 23 to telescope into a fixed sector-shaped part 33 when engaged by a bin 3, Figs. 2 and 5, which is raised and tipped by a lifting cradle 1, 2. A closure plate on the telescoping hood is formed with an orifice 16 engaged by the mouth of the bin and normally closed by a flap 19 pivoted at 20 to the part 15 of the hood and operated by tooth gearing so that it automatically opens near the end of the inward movement of the hood and closes in the initial part of its outward movement. A hinged lid on the bin is opened and closed bv engagement of a hook 24 on the flap 19 with the handle 25 on the bin. The flap 19 is integral with a pinion 21, Fig. 6, engaging teeth on a segment 22 pivoted about the axis 23 and normally coupled to move the hood 15 by a spring pressed ball (not shown) on the hood which engages a recess 29 in the sector. As the bin 3 pushes the hood 15 and the segment 22 about the axis 23 the flap 19 remains closed until the segment 22 is arrested by a stop 31. Continued movement of the bin and hood then causes the pinion 21 to be rotated to open the flap 19 and with it the lid of the bin as shown in Fig. 5. During the reverse motion the flap 19 and the lid of the bin are closed when the segment 22 is held from movement with the hood 15, to which it is coupled by engagement of the spring passed ball within a further recess (not shown), by a rear stop 30. The hood 15 is mounted within a further hood 34 also pivoted about the axis 23 and moved by an abutment 37 engaging abutments 38, 38<SP>1</SP> on the hood 15. Inward movement of the hoods 15, 34 is limited by an abutment 35 on the hood 34 adapted to engage a stop 36 on a fixed hood 33. In an alternative construction the teeth on the segment 22 are replaced by a row of pins on an intermediate hood similar to the hood 34. The intermediate hood is coupled to the hood 15 by hook devices which are released to permit relative movement of the moving hoods when the intermediate hood is arrested by stops on the fixed outer hood. The cradle 1, 2 carries rollers 8 running in guides 9 at the rear of the vehicle. A hydraulic jack 12 pivoted at 10 to a bracket on the cradle and at 14 to the vehicle raises the cradle and bin until the upper roller 8 engages an abutment at the upper end of the guides 9. Continued operation of the jack 12 causes the lower rollers 8 to leave the guides 9 so that the bin and cradle tip about the axis 23 to bring the upper edge of the bin into register with the orifice 16 in the hood 15. The charging apparatus described may be manufactured as a fitting for attachment to existing vehicles.
