Abstract: 1,188,358. Mower. C. VAN DER LELY N.V. 23 May, 1967 [17 June, 1966], No. 23996/67. Heading A1F. A mower propelled by a vehicle such as a tractor 52 comprises rotatable mowing elements 8 provided with cutting members 39 and arranged in a line, and is characterized in that at least one pair of mowing elements 8 is so disposed that the paths 64 traced by the outer tips of the cutting members 39 of the pair touch or intersect substantially in the track of a ground wheel 65 of the tractor 52. The blades 39 of each element 8 are attached by pins 35 locked by readily accessible split pins 36 to a U section member 31 fixed to a drum 17 which is rigid with a hollow driven shaft 9. Driving shafts 43 journalled within frame beams 7 interconnect the elements 8 through gearboxes 45, and to allow vertical swinging of the beams 7 universal joints 54 transmit power to the inner gearboxes 45 from a central gearbox 56. A further shaft 60 with universal joints links the gearbox 56 to the tractor power take off shaft. Barrel-shaped ground wheels 18 allow the elements 8 to follow the ground contour, and chains (53), Fig. 2 (not shown), connected to a lever 51 pivoted to the tractor frame are acted on by the tractor three point hitch to raise the beams 7 into vertical planes. Means for imparting an upward force on cut crop during operation comprise ridges 27 on the outer surface of each drum 17. In an alternative embodiment, Fig. 4 (not shown), a single pair of mowing elements 8 is provided, and further, Figs. 5-12 (not shown), an alternative embodiment of the mower element mounting and driving mechanism is disclosed.

Filed: 1920-08-23
Abstract: 156,073. Schworetzky, G., and Graaff, C. Dec. 31, 1919, [Convention date]. Addition to 148,227. Fire - extinguishing by foam. -In methods and devices of the kind described in the parent Specification for producing foam for fire-extinguishing &c., the pressure water is introduced through an inlet w into an annular chamber k and passes by the shortest possible path in an upward direction through oblique slits in fixed and movable plates n, p, the slits being so arranged that the water lifts the movable plate p and is at the same time given a rotary motion before coming into contact with the chemical powder in the upper compartment. The water thus impregnated passes by the shortest possible path through passages, opened by the raising of the plate p, into an annular chamber k<1>, and thence passes with a rotary motinn into contact with the second chemical powder in the lower compartment, the foam produced being discharged through a central tube r. When a more fluid foam is required, additional water is admitted from the annular chamber k through a valve v<1> into an annular chamber k<11> and thence into the lower compartment.

Abstract: 1493225 Rotary positive displacement devices CATERPILLAR TRACTOR CO 14 June 1976 [23 Oct 1975] 24532/76 Heading F1F A rotor for a slant axis rotary positive displacement fluid-machine such as a slant axis engine or pump, Fig. 1 (not shown) comprises a plurality of apices 42, Figs. 2 and 3, each having a sealing arrangement comprising an apex seal 62, disposed in a groove 60 and acted on by a spring 64, a bolt seal 68 disposed in a bore 66, a piston 70 acted on by a spring 72, and a passage 80 providing fluid communication between the bore 66 and the outside surface of the rotor. The apices of the rotor may be formed on the flange (40) Fig. 1 (not shown) of a slant axis mechanism and peripheral seals 50 may be provided to define with the apex seal, the bolt seal, the rotor and a stator in which the rotor is mounted, three chambers A, B, C, Fig. 3, at each apex. When fluidpressure in chamber A exceeds that in either chamber B or C, fluid under pressure is admitted to the bore 66 via the passage 80 and acts on the piston 70 which contacts the bolt seal 68 which is forced into sealing engagement with the surface 16. In the case of a pressure difference between chambers B and C, the seal 62 is displaced to abut one of the side walls of the groove 60 to allow fluid to flow to the annular space 78 between the balance piston 70 and the bolt seal 68 where it acts directly on the bolt seal 68.
