Title: Improvements relating to revolving doors
Inventor: SMITH HOWARD JOHN TREWEEK
IPC: E06B3/90
Filed: 1965-11-05
Abstract: 1,084,708. Revolving door installations. D. A. RIDDLE. Aug. 25, 1966 [Nov. 5, 1965], No. 47121/65. Heading E2M. A revolving door installation comprises a motor driven rotary door assembly having a floor 3 and which is divided by partitions 2 into a series of compartments each of which has a pedestrian platform 18 rotatably coupled to door driving mechanism so that when the door assembly rotates through a predetermined angle a compartment platform is automatically turned through a-compensatory angle such as will facilitate exit of a pedestrian from that compartment. In a preferred embodiment, shaft 1 carrying partitions 2 is coupled at its lower end to the upper element 31 of a dog clutch, the lower element 30 of which is coupled to hub 22 of floor carrier 8 and driven by shaft 17 rotated by electric motor 21 via gearbox 20. The circular floor 3 has rollers 5 on its periphery which run on a track 6 and is supported by webs 7 on carrier 8. Pedestrian platforms 18 are supported by spigots 9 and springs 10 on arms 11 fixed to shafts 12 in bearings at the periphery of carrier 8. Each shaft 12 has a pulley 13 engaged by endless driving belts 14 which also pass around pulleys 15 on pedestal sleeve 16. A microswitch (see Fig. 4) may be provided beneath each platform 18 in circuit with the electric motor so that whenever a person steps on or is standing on the platform the motor is energised to rotate the door and platforms. Alternatively starting and stopping of the revolving assembly may be controlled by means of photoelectric cell assemblies in each compartment (see Fig. 5) or in the approach and departure paths to and from the installation. A pressure sensitive device or proximity switch may also be used in the latter instance (see Fig. 6). The dog clutch is constructed so that in the event of excessive pressure upon the partitions the clutch elements disengage thus causing microswitch 41 to operate and stop the electric motor. Alternatively, each partition may have a switch controlling the electric motor, displacement of any partition from a radial position as a result of excessive force causing operation of the associated switch to stop the motor (see Fig. 7). In order to ensure that arrest of the revolving door assembly occurs only when a compartment is aligned, with an exit or entrance, a switch located peripherally of the assembly for operation by cam surfaces on the partitions may be provided. Manual rotation of the partitions, the floor remaining stationary, may be carried out after withdrawing a pin coupling the partitions to the floor (see Fig. 8). An hydraulic pump and motor may be used instead of an electric motor and mechanical drive and each pedestrian platform may have its own electric or hydraulic motor. Chains and sprockets, or gears, may be used to transmit rotary motion to the platforms instead of belts and pulleys.

Filed: 1969-09-29
Abstract: 1,273,757. Mowers. JACOBSEN MFG. CO. 29 Sept., 1969 [18 Oct., 1968], No. 47769/ 69. Heading A1F. A tractor supports gauged, castor mounted mowers 57, 58, 59 directly in front of each of the ground wheels 11, 12, 13. The engine and other parts of the tractor are distributed such that the weight of the tractor and mowers is evenly placed on each of the ground wheels and the seat 43 is placed in a position over the centre of gravity of the machine. Steering of the tractor is effected by articulation of the rear wheel 13. Motive power is supplied by a rearwardly mounted engine 46 through a fluid transmission conducted from the pump (168) Figs. 4, 10 (not shown) through the hollow framework of the tractor and by flexible tubes 177, 179 to the rear mower motor; by tubes 172, 173, 174, 175 to the two front mower motors; by pipe lines 164, 166 to the two front wheel traction motors and by tubes 102 to the cylinder 97 powering the mower lift ram 101. The two front mower motors are fed by the transmission in parallel to give a differential effect. When out of the neutral position the mower motors are also in parallel drive which drive is in series with the traction drive to the wheels so that the tractor speed is in a fixed ratio with the mower rotation. Further the drive to the mower lifting ram 97 is similarly in proportion to the tractor speed. Lifting of the mowers is accomplished on extension of the ram which through the links 103, 121. pivots cam plates 113, 127 upwards in a vertical plane to engage rollers 114, 128 respectively pivoting the lift arms 74 about pins 76 on the tractor frame. This lifts the front mowers mounted on the other end of the lift arms 74. The rear mower is lifted by means of a linkwork 121 also powered by the ram 97 which includes an adjustable lost motion coupling before it operates the cam plate 138. In this way the mowing may be started and finished along a line at right angles to the mowing direction. The cam plates are profiled with projections 119, 154 so that when in the raised operative position the ram need not be powered to hold the mowers off the ground. To lower the mowers the drive to the ram must be reversed to disengage the cam plates at which time the lowering of the mowers is cushioned by springs 155.
