Abstract: 5412. Jones, L. M., McLeod, C., and Clokey, W. J. March 14. Reaping-machines.- Relates to detail improvements. The height and inclination of the main frame are adjusted by the following mechanism :- The axle B of the main wheel carries at one side a pinion b<1> engaging a pinion D on the main crossaxle E of the machine. The axle B at its outer end carries an arm b, on the end of which is pivoted a brace J connected to the draught-pole. A brace J<1> at the opposite side of the pole is pivoted to the machine substantially in a line with the axle B. The braces J and J<1> are connected together by a cross-bar J<2>. The brace J carries a bar j, on which the seat standard is supported. The tilting-lever F<2> is attached to a rock shaft f<1>, mounted in bearings on the pole and on the brace J. A crank on the end of the shaft f<1> is connected by a link f<5> to a portion of the main frame, so that, by operating the lever F<2>, the frame is tilted rearwardly o r f o rwardly around a centre line passing through the axle B and pivot of the brace J<1>. The frame is raised or lowered by means of a worm I operated by a crank shaft i and gearing with a worm-wheel G on a spindle g, on which is also secured a. wheel H gearing with a segment d on the shaft E carrying the pinion D. On operating the pinion D by the above-described gearing, it rolls around the pinion b<1>, and the frame is raised or lowered. In order to operate the gate in the cam track which determines the movement of the platform rakes, and to prevent the rakes from sweeping the platform when required, the following mechanism is provided :- The gate P', Fig. 1, is mounted on a spring- actuated spindle provided with an arm 5, Fig. 2, which is adapted to be engaged by a notched lever R., The lever is provided with a projection adapted to engage one of a series of teeth on a drum S adjustable longitudinally on a square spindle o'. The drum S is adjusted by means of a fork s connected to a spring arm T, the upper end t<2> of which is cranked and can be fixed between projections on a plate according to the adjustment required. The shaft o<1> carrying the drum S is provided with a worm-wheel driven by a worm n on the spindle of a bevel-wheel N gearing with a bevel pinion on the end of the shaft E. The shaft o<1> is mounted in pivoted hangers o', which may be swung outwardly to throw the wormwheel out of gear with the worm n, and thus prevent any of the rakes sweeping the platform. The hangers o<2> are swung outwardly by a rod V connected to an eccentric pin v operated by rack- and-pinion gearing from a link 8 connected to a rock-shaft mounted parallel to the shaft f<1> and provided with a foot-plate. The hangers o<2> are returned to their normal position, when pressure is taken off the foot-plate, by a spring acting on the above-mentioned rack. The inner portion m of the grain table is fixed to the frame, and the main portion M is hinged to the part m at 12, 12. A pivoted bail W can be fixed in either of the positions shown in full and in dotted lines in Fig. 2, and in the latter position forms a fulcrum support, so that the grain table M may be folded up on its hinges 12, 12. The main inner divider bar 13 carries corn-lifting bars 15, which are secured to the bar 13 hy a special pin joint, so that they may be released from their operative position and allowed to fold over with the grain table M. The pitman is connected to the heel of the knife-bar by means of a pin which is held in position by a spring catch pivoted on the pitman.
