[Class 78 (i)] In a shoot for discharging coal or other lumpy material, in order to cushion the impact of the material with the shoot a layer of the material is formed in the shoot adjacent the entrance by means of a transverse bar 1 lowered to within a few inches of the base of the shoot. The bar is counterweighted and, in the form shown, slides in guides 6 and is raised and lowered by the chain and sprocket gear 9 ... 14, being locked in the lowered position by a clamp 15 engaging the handwheel 8. In modifications, the bar may be raised and lowered by a link and lever system and instead of the guides 6 the ends of the obstruction bar may be carried by radius rods.
