Title: Improvements in and relating to Electric Switches.
Filed: 1902-06-17
Granted: 1903-05-14
Abstract: 13,741. Lake, H. H., [General Electric Co.]. June 17. Electric railways. -Relates to a n e l e t r o magnetic switch provided with a time-lag device to hold the switch closed for a short time after the operating means has acted to open it, and applicable in a surfacecontact electric railway system to prevent the connection from the feeder to the sections of the working conductor from being broken when the collector shoe jumps or breaks contact with the conductor momentarily. Connection is made between two contacts a by a spring bridge A on the stem of a solenoid core C when current passes through the solenoid B. A catch on a spring lever b<1> then engages with the lower of a pair of toggle-levers a<1> connected to the bridge A to lock the core C in the raised position. When the solenoid circuit is broken, a loose armature F falls and oscillates a lever j, thereby rotating toothed wheels r<2> and r and flyer vanes q. After a short interval of time, a pin t<1> on the wheel r strikes the upper end b<3> of a spring lever b, with the effect that the locking-catch is released from the lever a<1>, thereby allowing the core C to fall and open the circuit of the contacts a. On again closing the circuit, the pin t<1> depresses the pivoted piece b<3> without affecting the levers b and b<1>. The time-lag device may be applied to switches having other means than those described for closing the switch or holding it closed.

Title: Improvements in Dental or Surgical Engines or Drills.
Inventor: BERCUT JULES JOSEPH
Filed: 1903-08-14
Granted: 1904-07-14
Abstract: 17,655. Bercut, J. J., and Cattin, A. H. Donat-. Aug. 14. Dental and like engines.-Relates to dental or surgical engines or drills. The tool-holder b, Fig. 2, is rotated by clockwork contained in a casing a, and consisting of a spring c which rotates a wheel d driving a train of wheels f, f<1>, f<2>, f<3>, f<4>, mounted between plates g, g<1>, a ratchet-wheel concentric with the wheel d being provided with a check-pawl. The holder b may be driven at different speeds by connecting it with one or other of the arbors of the wheels f, f<2>, f<4>. A brakej, actuated by a button k, bears against a grooved fly i on the axis of a wheel h' gearing with a wheel on the axis of a wheel f<4>. The spring-barrel is wound up by rotating the cap a', a clutch a<2> communicating the motion to the spindle c', to which the free end of the spring c is attached. Or the cap may be fixed, and the spindle c<1> have a squared end to receive a key. In a modification, the mechanism is contained in a case through one side of which the axes of three of the wheels of the train project, so as to receive the tool-holder. In an arrangement in which the drill can be rotated in either direction, a ring n, Fig. 8, driven by the spring-barrel has internal and external teeth, and the axle r containing the holder b rotates between plates q, q<1>, q<2> and carries a pinion r<1> gearing with a pinion s, on the axle of which is a wheel s<1>, which, by means of a stud t, can be put into gear with either of two wheels gearing with the internal and external teeth of the ring n. A stem u, Fig. 10, having a detent u<1>, carries, at its upper end, a head v which is inclined on opposite sides and terminates in a groove. When the pin t engages in this groove, the detent u<1> prevents the ring n from rotating, but when the stud t is moved into either of the positions 1 or 2, the spring w disengages the detent from the ring and allows the tool to rotate. The spring-barrel may be wound up by means of a cord passing round a pulley loose on the axis of the barrel and containing a spiral spring ; ratchet teeth on the side of the pulley are engaged by a spring- pawl mounted on a toothed wheel on the axis of the barrel, so that, on pulling the cord, the barrel is wound up, and then, on releasing the cord, the spring returns the pulley to its original position. The outer end of a lever bearing against a fly on the axis of one of the wheels of the train, may bear against an air bulb connected by a pipe to an air ball lying on the ground, so that, when the latter is compressed by the operator's foot, the fly is released and the mechanism put in motion. Similar means may be applied to mechanism in which a weight is used instead of a spring. Instead of the fly being on the axis of one of the wheels of the train, it may be mounted on a shaft driven from the shaft to which the flexible drill-shaft is connected.
