Title: Improvements in or relating to power transmitting devices
IPC: F16D67/02
Filed: 1954-06-17
Abstract: 775,023. Disc brakes. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 16, 1955 [June 17, 1954], No. 17760/54. Class 103 (1). [Also in Groups XXIV and XXXV] A clutch-brake driving device for shoe sewing machines comprises a centrifugal mechanism and a rotary inertia member which control the slip in the clutch to maintain a substantially constant speed of a driven member (see Group XXIV). The driving shaft 16 of an electric motor carries a flywheel 20 which can be engaged by friction segments 22 on a disc 24 carried on an axially movable hollow driven shaft 30. The disc 24 can be braked by moving it axially into engagement with friction segments 38 on a flange 36 integral with a stationary surrounding casing 34. A rod 60 within the hollow shaft 30 has a coarse pitch screwed engagement at 67 with the hollow shaft and is connected at its other end through a ball thrust bearing 62 with a screwed stud 46. A treadle is connected by links 50 to the end of the stud 46 which is in screwed engagement with a threaded bore in a supporting arm 44, so that operation of the treadle moves the rod 60 &c. axially for clutch or brake engagement. The inner end of the rod 60 carries an inertia member 58, so that on acceleration or deceleration of the driven sewing machine, the shaft 30 screws along the thread 67 to decrease or increase the clutch engaging pressure and thus control the amount of slip in the clutch to restore the original speed of the sewing machine. Pins 77 on the inertia member 58 are connected by links 79 to the ends of centrifugal weights 74 pivoted on studs 26 carried by the hollow shaft 30. Springs 66 are adjustably tensioned to bias the weights 74 radially inwards. When the electric motor is running and the driven shaft 30 is at rest, operation of the treadle to engage the disc 24 with the flywheel 20 begins the operation of the shoe sewing machine. The inertia member 58 acts during acceleration of the driven shaft 30 to keep the clutch engaging pressure within the limits of available torque. As the speed of rotation increases, the centrifugal weights 74 move radially outwards, and the inertia member 58 is turned relatively to the driven shaft 30 to move the clutch plate 24 away from the flywheel 20 and reduce the torque transmitted to the driven shaft. If the treadle is not further moved, the driven shaft 30 will be rotated at an approximately constant speed irrespective of the load placed upon it. If the treadle is operated to stop the machine, the clutch plate 24 is pressed against the brake flange 36 and the centrifugal weights move inwardly until the inertia member 58 reduces the brake engaging pressure. In assembling the machine, a main casing 10 is screwed at 80 into the end casing 34 until adequate brake engaging pressure is obtained with the treadle in the brake engaged position, and is then locked by a screw and lug arrangement. An impeller 86 on the motor driving shaft 16 draws cooling air through holes 90, 92, 94 and ejects it through holes 88.

As shown, an apertured annular shield 15 having an applicator 16 is rotatably mounted on the tube around an annular window 20. The shield is adjusted by means of a hand-wheel 17, which corresponds to a hand-wheel 18 rotating the anticathode 21. An annular member 80 surrounds the end-member 43 of the tube and is rotatable with respect to it by means of pegs 81. The member 80 has a double flange overlapping the shield 15 and a covering member 82, and is provided with pins 83 co-operating with brake shoes 85 pivoted on pins 86. The pins 86 and similar pins 90 carry anti-friction rollers 88, 89 engaging within the shield 15. The pins 86 also project through slots 86<a> in the member 80 and are secured therein by split pins. Anticlockwise rotation as shown in Fig. 4 of the member 80 locks the shield 15 in position. Alternatively, the brake-shoes can be operated by a spreading cam rotated by a lever. A weight 95 on the shield 15 balances the applicator 16. The member 93 surrounding the shield 15 has an aperture 94 and a slot 97 for the insertion of a shutter or filter.
