LOO- MACHINES FOR SOWING— tal spindle on which are fixed the teeth or brushes, which, agi- tating the seeds in the box, cause them to fall through the holes into the tubes. Motion is given to this spindle by means of a toothed wheel upon the axle of the wheel E. This moves a small intermediate wheel, and this again the wheel K placed upon the end of the spindle. In this manner the spindle with its brushes or wheels revolves amongst the seeds, and by the motion which it gives to them, causes them to fall through the holes into the tubes, whence they are conveyed to the ground. When the spindle is stopped scarce any seeds fall through the apertures, and by means of a lever L, the workman has the power of throwing the moving wheel out of geer, and thus stopping at once the revolution of the spindle. BB are the shafts attached by means of hinges to the machine, between which the animal of draught walks; and A A are the handles upon which the workman presses, and by elevating which, he is enabled to lift up the seed-box and coulters, so that the lat- ter may, if required, be raised entirely out of the ground. G represents a part of a long wooden bar, with a rod and sharp piece of iron H, fixed to it by hinges at I. The purpose of this is, that when the machine moves across ridges, which is the way in which it is often employed, a mark or rut may be made in the ground: and when it returns the animal of draught walks in the rut or track which had thus been formed, and which is accordingly the guide or mark by which the workman is enabled to direct the course of the machine. This marker is made to be lifted to either side as may be required. The at- tachment of it to the machine is not shown, on account of the smallness of the Please note that these images are extracted from scanned page images that may have been digita
