Title: Safety device for trains and other vehicles having a single driver
IPC: B60L3/02
Filed: 1931-07-07
Abstract: 371,692. Controlling vehicles. BIANCHI, G., 18, Via Jacopo Nardi, Florence, Italy. July 7, 1931, No. 19586. Convention date, July 8, 1930. [Class 103 (i).] A device for stopping a vehicle if the driver becomes incapacitated comprises a step or seat which is moved by the instinctive movements of the driver so as intermittently to make and break an electric circuit or which controls a further device adapted if the circuit remains either made or broken for a predetermined interval, to apply the brakes and cut off the power. The step or seat comprises a circular plate D mounted to oscillate about a central support P against the resistance of springs. A series of peripheral contacts C are connected alternatively to the positive and negative poles of a source of current or as shown alternate contacts are connected to one pole and the plate D to the other pole the other contacts being insulated. The. circuit of an electromagnet E is thus made and broken by the tilting movements of the plate. The armature H of the magnet has projections T, T<1> whereby in either of its extreme positions it holds a rod A in position with a half-nut Q slidable thereon engaged with a screwed shaft V driven either from the vehicle or by an independent power source. If on account of illness the driver is supported inert upon the plate D or leaves his position so that the circuit of the magnet E remains either made or broken, the nut Q travels along the shaft V until it engages in succession members K, K<1> which cut off the power.and apply the brakes. Normally, however, by reason of the movements of the driver, the interval during which the magnet is energized or de-energized is insufficient for this purpose and the nut is disengaged and drops back to the starting point.

[Also in Group XXIII] In cutting tobacco issuing through a mouthpiece 10 by rotated disc knives 13 mounted planetwise on a rotated drum support 14, the continual wear on the knives by grinding discs 20 is compensated by continually moving out the mouthpiece 10. The mouthpiece 10 is moved out by a slide 35 operated by a piston in a hydraulic cylinder 70, the pressure being generated in another cylinder 72 by a piston 73 on a screw spindle operated by a worm drive 36. One or more rotated grinding discs 20 also follow the wear of the disc knives 13 by being mounted on a slide operated by hydraulic cylinder and piston under the same hydraulic pressure generated by the piston 73 pushed by its screw spindle in the worm drive 36. An independent motor 76 rotates the grinding wheel 20. The same hydraulic pressure also moves, in the direction A, a trueing diamond 31 for the grinding wheel 20 to take up the wear. The diamond 31 on arm 32 is swung across the face of the grinding wheel 20 by gearing 80. Dust is sucked out of the casing 81 by a pipe 82. The hydraulic circuit may be replaced by mechanical means, Fig. 3 (not shown). The disc knives 13 may be rotated by individual motors 16, Fig. 3 (not shown). Various forms of disc knives with detachable cutting rims are in Figs. 5, 6 and 7 (not shown).  Reference has been directed by the Comptroller to Specification 701,400.
