Title: Improvements in lawn mowers
IPC: A01D34/54
Filed: 1948-09-06
Abstract: 653,202. Lawn-mowers. RANSOMES, SIMS & JEFFERIES, Ltd., and PLUMB, A. B. Sept. 6, 1948, No. 23448. [Class 6(ii)] A lawn-mower has a rear framework carrying the cutting mechanism and provided with a ground roller and a front framework mounted on side wheels, the two frameworks being pivotally connected and relatively adjustable to regulate the height of cut by means of a handoperated spindle rotating in the rear framework and engaging a nut in the front framework. Fig. 1 shows a mower in which each side frame is in two parts 1, 2. The side parts 1, 1 are rigidly connected by a cross-stay 3 to form a rear framework carrying the axle 4 of a ground roller 5, the shaft 14 of a cutting cylinder 6 and a bottom blade 7. The side plates 2, 2 are rigidly connected to a tubular cross-stay 8 to form a front framework provided with ground or side-wheels 9, 9. The two frameworks are pivotally connected, bosses 10, 10 on the side plates 2, 2, Fig. 2, being mounted to oscillate on extentions of bosses 12, 12 on the side plates 1, 1. The bosses 12, 12 form housings for ballbearings for the shaft of the cutting cylinder. The side plates 2, 2 have bosses 15 fitted with bearing bushes 16, 16 for the stud axles 17, 17 of the side wheels. The side wheels have spur gears 18, 18 driving pinions 19, 19 on the shaft 14. Mounted to rotate in a swivel 23 on the cross-stay 3 is a screw 20 engaging in a cylindrical nut 26 mounted to swivel in the cross-stay 8. To adjust the height of cut, the screw 20 is adjusted by rotating the handle 21. This rotation produces relative movement between the front and rear frameworks, the rear framework pivoting about the ground roller so that the cutting cylinder and the bottom blade are raised or lowered according to the direction of rotation. The bottom blade 7 is mounted on a carrier 27 having end bosses 28 oscillating on the roller axle. The blade 7 is adjustably held relative to the cutting cylinder by spring-loaded bolts 32 passing through the carrier 27 and a web 33 of each side plate 1. Upward movement of the bottom plate is limited by stop screws 29. When the lawn-mower or the cutter-mechanism is motor-driven each side frame is in one piece pivotally mounted on the axle of the ground roller, while supported forwardly on an axle having cranks for the stub axles of the side wheels. A cross-stay rigidly connects the side plates and carries spaced brackets supporting the motor. The height-adjusting screw is held between crank arms on the forward axle and passes through a bar carried by the brackets. Rotation of the screw moves the crank arms to swing the forward axle about the stub axles of the side wheels and thus raise or lower the side plates and hence the cutting-mechanism.

Abstract: 1,115,733. Vehicle suspension. FABRICA ITALIANA MAGNETI MARELLI S.p.A. 8 June, 1965 [5 June, 1964], No. 24237/65. Heading B7D. In a vehicle pneumatic suspension, suspension units D 1 , D 2  for individual wheels or left and right wheels on the same axle are connected to fittings 62, 64 of a levelling valve A which also has a fitting 46 for connection to a supply of compressed air from a supply C through an isolating valve B. The levelling valve A is connected to the body and a lever 16 connected by a pivot shaft 14 to the valve is connected to the suspension. A cam 18 is connected to the pivot shaft 14 and engages a roller 20 mounted in a hollow push-rod 22. The valve casing forms cylinders 36 and 26 for the reception of pistons 28 and 34 connected by a piston-rod 30. A spring 47 urges the pistons 28 and 34 downwardly into the position shown. The fittings 62 and 64 are sealed off by valves 54 having stems engaged in an annular groove 48 in the piston 34. The piston set 28, 30, 34 is hollow and is sealed by a valve 40 acted upon by a spring 42. An aperture 68 connects the interior of the piston set with the space G between the cylinders 26 and 36 and at its upper end the interior of the valve is connected to atmosphere by an aperture 25. When the isolating valve B is closed, the levelling valve is in the position shown and the suspension units are isolated from one another. When the isolating valve B is opened, compressed air is admitted to the space F causing the piston set to rise against the abutment 45 and opening the valves 54. If the suspension height is such that the push-rod 22 opens the valve 40, compressed air will flow into the units via the space G and valves 54, but if the push-rod does not contact the valve 40, air will flow from the units through the space G, interior of the push-rod and through aperture 25 to exhaust. Modifications are described in which the stems of valves 54 are shaped to engage a correspondingly shaped shoulder on the piston set, and in which the valves 54 are vertically disposed and are tripped by a flange on the piston set.
