Abstract: 509,227. Centrifugal machines. PATENTVERWERTUNGS-GES. HERMES. Nov. 29, 1938, No. 34796. Convention date, Nov. 29, 1937. [Class 23] A safety device for centrifuges and the like, whereby the drive is switched off and the brakes are applied before the cover is opened, has its actuating rod or like part held by a part of the cover locking-device against the action of a spring, in the position in which the motor is switched-on and the brake is released. In the form shown, the centrifuge bowl 3 is enclosed by a casing 1 standing on resilient feet 2. The bowl is driven by an electric motor 5 and a brake disc 9 at the lower end of the bowl shaft 4 rotates between two jaws 10, 11 which can be moved to braking position on the disc by means of a Bowden cable 12 secured to the fixed plate 13. The spring 14 presses on the pivoted lever 16 and maintains tension on the inner wire 18 of the Bowden cable which tends to apply the brake. The bowl and motor assembly is supported on a partition in the casing by means of the spring 7. The end of the lever 16 is mounted with a clearance between two nuts 23, 24 on the vertically sliding rod 19, and the lever 25 of the motor switch 8 is similarly mounted between the rings 26, 27. The upper end of the rod 19 terminates in a hook 33, and a toggle device 32 is arranged between the hook and the bearing 20. The cover 28 swings on the hinge 30 and has a rim covered with rubber 29 ; it is held closed by a locking lever 31 attached to the cover and locked by the toggle. When the cover is closed, the locking of the toggle raises the rod 19 and operates the levers 25, 16 to close the motor switch 8 and to release the brake jaws 10, 11. When the toggle is released for the purpose of raising the cover, the rod 19 drops under the action of the spring 14 and gravity to open the switch 8 and to put on the brake.

Abstract: 451,481. Drawing. HARTLEY, T. W., The Old House, Seisdon, Wolverhampton. Dec. 31, 1935, No. 36021. [Class 83 (iv)] A drawbench having a carriage carrying jaws which engage the stock and a part engaging a poweroperated driving member, has a retaining device for keeping the part which engages the driving member from engagement therewith during the return travel, automatic operating means being provided for actuating the retaining member and for releasing the gripping jaws from the work at the end of a drawing operation. A drawing- carriage 33 runs on wheels 34, 35 on frame members 1 which are spaced by the central channel bars 2. The carriage is driven in the drawing stroke by a chain 7 engaged by a hook 42 on the carriage, and is returned by a rope drive 29. The chain may be driven from an electric motor through gearing 17, 16, and a shaft 15, further gearing 19, 20 and a belt 23 driving the member 29 when clutch parts 26, 27 are engaged. The hook 42 is raised from engagement with the chain 7 at the end of a drawing operation by the ends of a pin 44 riding up inclines 82, and then into the forked ends of levers 83, continued movement causing the levers 83 to rise and a weight 86 to be swung past the vertical position, when it falls to a position limited by the stop 88. The hook is thus swung clear of the chain, and a notch 47 is engaged by a flat surface 56 on a pin 54 to retain the hook throughout the complete return stroke. At the end of this movement a rod 48 strikes an abutment 59 adjacent the die 5 causing levers 52, 53 to be rocked on the pin 54, and the hook is permitted to drop into engagement with the chain. The gripping jaws 61 engage inclined faces in their holder, and are moved to grip the stock by movement of the rod 48 through a lever 68 and a pin 65 engaging the ends of the jaws. The rod 48 is returned when a cam 81 is engaged by a roller 80 on a bell-crank lever 74, 76 connected to the lever 68 through a rod 78. The clutch parts 26, 27 are engaged to return the carriage by the driving member 29, by depressing a pedal 106 which actuates the clutch through a series of levers, and a rod or cable 96. The clutch is automatically disengaged by a roller engaging a lever with a cam action, thus rocking a shaft 98 in the lever system. The freed work falls on to deflector plates 117 and is delivered by them to the side of the machine. The plates are swung clear on passage of the carriage but are returned by counterweights secured to the plates by cables. Specification 451,480 is referred to.
