Abstract: 372,765. Machines for working land. MURRAY, J. B., Astwick Manor Farm, Hatfield, Hertfordshire. Feb. 3, 1931, No. 3487. [Class 6 (i).] In a machine comprising a rotary shaft on which are mounted arms for carrying ploughshares, which arms are arranged to slip relatively to the shaft on meeting an obstruction, the arms are each coupled to the shaft by a spring-loaded dog clutch having a single dog the leading edge of which is inclined, for the purpose of insuring that an arm after slipping will resume its proper position relative to the other arms at the end of a revolution of the shaft. The rotary shaft is mounted in ball bearings protected from dust by felt washers. It is driven from land wheels or from the powertake-off shaft of a tractor 10 through chains 14 and a clutch and gearing in a case 13. The clutch may be operated by a lever 47 and a cord, and the gearing may be connected to the power shaft by an extensible and universally jointed shaft 15. The arms 30 carrying the shares 31 and mouldboards 32 are adjustably bolted to flanges 20 on sleeves 19 on the rotary shaft 12. Each sleeve 19 is formed with a single V-shaped dog 22 and a notch 23 engaging with a corresponding notch 23 or dog 22 of the adjacent sleeve or of end members 25 splined on the shaft 12. End compression springs 28 press the sleeves 19 and members 25 into contact. Dust is excluded by sleeves 24, 27 and felt washers 21. The shares are arranged helically around the shaft so as to come into operation successively. The helix may make one or two turns around the shaft 12, or there may be a right-hand helix and a left-hand helix. Land wheels 34 are mounted on a cranked axle 33 which may be rocked to raise the plough by means of " self-lift " mechanism comprising quadrants 36 engaging pinions 38 on the wheels 34. A catch 40 for holding the wheels 34 in lowered position may be released by a lever 39 and trigger 41. The depth of work is regulated by screws 43 engaging with the crank arms of the axle 33. A curved guard 45 above the shaft 12 carries spring tines 46. The thrust along the shaft may be balanced by the use of landslides attached to the shares, or a thrust wheel mounted to run in the last furrow cut previously. It may also be balanced by moving the shaft 12 into an inclined position. The mouldboards may be made up of curved prongs or strips.
