Title: Improvements in centrifugal fan rotors
Inventor: LETTS ROBERT ARTHUR
IPC: F04D29/28
Filed: 1958-07-14
Abstract: 864,544. Centrifugal fans. AIRSCREW CO. & JICWOOD Ltd. June 8, 1959 [July 14, 1958], No. 22462/58. Class 110 (1). In a centrifugal fan rotor of the kind in which the blades are adhesively secured by their extremities to opposing supports, relative outward radial movement of the blades is prevented by interengagement of their extremities with the supports, the interengagement also relieving the adhesive joints of centrifugal load. Fan blades 1 formed with flanges 8 engage in channel-section supports 2, 3 and are secured by adhesive. The fan blades are preferably wider radially than their flanges, Fig. 3, to form shoulders butting on the circumferential edges of the supporting channel 9. One edge of the channel may be turned in as at 13. In alternative constructions a continuous rib 14 may be provided in the support 2, Fig. 5, or spigots 15 on the flanges 8 engaging in holes in the supports 2, 3, Fig. 9. The flanges 8 are shaped so as to be self-locating, even on rotors of different diameter from that for which the blades were designed. For variations of up to Œ20% the gaps between flanges are small enough to be filled with adhesive. The side edges of the flanges 8 may be either truly radial, curved so that adjacent flanges nest into each other, or inclined to the radial where overlapping blades are required.
Patent GB-382338-A (GB)
Title: Improvements in brakes
IPC: B60T13/74
Filed: 1931-08-08
Abstract: 382,338. Brakes. BRETTELL, F. G., 59, Chancery Lane, London.-(Bendix Brake Co. ; 401, North Bendix Drive, South Bend, Indiana, U.S.A.) Aug. 8, 1931, No. 22485. [Class 103 (ii).] The starting motor for the engine of a motor vehicle is used to apply the brakes. Rotation of the motor in one direction starts the engine and in the other direction applies the brakes. The shaft 26, Fig. 1, of the starting motor 12 which operates the gear ring 44 on the vehicle engine flywheel by means of the usual starter drive 42 is extended into a gear housing 32 and carries a one-way roller clutch 50 and freely mounted on the shaft is a worm 60. The clutch 50 allows the motor shaft to revolve freely in one direction for starting the engine and in the other direction causes the worm 60 to be driven by the shaft by means of teeth 64 on the clutch and the worm. The worm drives a worm wheel 66 in such a direction that the teeth 64 are pressed together. The worm wheel encloses a coil spring clutch comprising a coil spring 70, Fig. 2, the ends of which engage lugs on flanged members 72, 74 connected respectively by shafts 86, 90 to the brake gear 84 and the brake pedal 88. When the brake pedal is depressed relative movement of the members 72, 74 expands the coil 70 into engagement with the worm wheel and the brake pedal, spring 70, members 72, 74 and brake arm 84 move together to apply the brakes and the effort of the motor is added to the operator's effort. To allow the brakes to be applied by the operator when the electric current fails as the worm gear is irreversible a spring 164, Fig. 1, is provided against which the worm 60 may be moved when the wheel 66 is rotated by movement of the pedal 88 and expansion of the clutch spring 70. The electric circuit is shown in Fig. 4 and comprises a starter switch which when depressed connects a contact 114 and lead 144 to earth through contact 106 and stem 100 and bridges contacts 116, 118 by means of a contact 108 so that a current passes through the field winding 164 and through the armature 136 in one direction. When the starter switch is released and the brake pedal 88 is depressed a switch 94 on the brake pedal tread is closed which connects a lead 148 to earth so that a circuit is closed through the armature in the opposite direction and through the field winding by means of contacts 108, 110 which bridge contacts 114, 116 and 118, 120 respectively.
