An encyclopædia of agriculture [electronic resource] : comprising the theory and practice of the valuation, transfer, laying out, improvement, and management of landed property, and the cultivation and economy of the animal and vegetable productions of agriculture, including all the latest improvements, a general history of agriculture in all countries, and a statistical view of its present state, with suggestions for its future progress in the British Isles. Agriculture. 2759. Rapson's slop drag for carriages going down hill (figs. 383, 389, and 390.) con- jKD sists of five or more of wood, pieces " united on the out- side by a strong jointed iron hoop ; the wood pressing upon the nave of the wheel. The first, a fixed pivot (a), from the hoop, is fixed to the under side of the frame of the cart; from the other extremity of the hoop of the brake proceeds a bar (6), which slides through the plate or socket (c) fixed to the side of the cart frame; a vertical perforation is made through the bar (b), just behind the plate, to receive the pin (d), which is likewise chained to the shaft: this pin, so placed, prevents any force applied to the chain from tightening the brake on the nave of the wheel. Fig. 389. represents the interior of a wheel on level ground, the nave surrounded by the brake, which, by its own gravity, is hanging loose, leaving the wheel perfectly free. Fig. 390. shows a wheel on a declivity, the chain drawn tight by the pressure of the breeching on the horse ; the brake, of course, closely surrounding the nave, and forming an effectual drag. Fig. 391. is a bird's-eye view of the whole apparatus, exhibiting the framing of the cart, the shafts, wheels, and brakes; the chains also are shown, passing from the bars on each side, each round a horizontal pulley on the shaft, and attached to the ends of the breeching. Thus it is evident that, when a cart, furnished with this drag, is going down hill, the load, pressing the breeching against the horses, d
