Definitions

  • This elastic or resilient means acting as a yielding coupling, may be termed a loose cou- W phng, and may consist of a spring, a magnetic i on opposite sides of a piston transmit the movements of a cranlr to the reciprocating, vspririg-supported cylinder.
  • Fig. 3 is a form illustrating the use ol'gas cushions.
  • the amplitude of the system is entirely dependent upon the damping'of the system, and if the damping decreases, the amplitude increases but the energy transmitted by the coupling will not be altered.
  • Fig. 4 is shown another form of an oscillating system of the kind described, provided with means for measuring the output or etlieiency.
  • a light-bar 26 To the movable part on rod 25 is secured a light-bar 26 by means of two arms 27 that is provided with a recording stylus 28. Inasmuch as the bar 26 shares the movement of the rod 25, thedeflection may recorded each time upon aistrip of paper travelling'over a paper support past the point 28.
  • the pendulum in its turn controlling an clock work, reacts in a controlling sense, that is to say does not permit the crank to make more than one rotation for each oscillation of the pendulum, 'lhe gauging oil the ratios of energy is etlected by the displacement of the V fastening members 43 and it, tor the coupling spring at; that is to say, by a change of coupiling.
  • I I v i igure it shows another modification, which lilrewise adapted tor the control at mechanisms tor-the measuring'ol time (clocks, or the like) by means of swinging systems.
  • 'lhe pitman rod 41,51 is omitted, and the elastic coupling in this. a single element, a coil spring 5% between the cranlr 53 and the pendulum.
  • the collecting springs may be *flat springs, and it would be possible in this connection to make use of air cushions or the like, instead of steel springs, .as "in Figs. 2 and 3.
  • the elastic means of the oscillat- 'ing system may beloc ated outside of the I 1 working cylinder'in the form of springs or" as separate compression cylinders as shown in Figure ll; or, second,.th e compression chambers which serve for the'collectlon or" accumulation .of energycoo erate with the" working chambers which are intended for the subsequent furnishing of the. energies to be consumed, as shown in Figure 12. 7
  • the elastic means may assume very different external configurations; thus, for example, visible springs have been employed in connection with some ofthe systems, while in other systems invisible earth-field performs endulum. But it is not only the earth field that may be used as a substitute for the elastic means, but in a general way any field of force may be utilized for the production of mechanical oscillations in combination with a mass; and of these, electric and magnetic fields of force are particularly adaptable.
  • Figures 15 to 17 illustrate a few additional forms of the invention as applied to oscillating electric motors of dynamo machines.
  • FIG 16 is a diagrammatic illustration of an armature oscillating in a'torq ue field.
  • This armature also, as shown in Figure 14, has to be connected with anelastic member, as a torsion spring, to tune the armature in conformity with the period of the triphase current.
  • anelastic member as a torsion spring
  • the coils should be short-circuited in anothelorder, coil 77, coil 78, coil 77 coil 78, and so on in succession; that is to say the coils 77 and .78 are alternately short--circuited, and the asynchronous motor is obtained.
  • the particu-' perform oscillations of a certain velocity it may be connected .to an elastic member which possesses an oscillating period of its own. in
  • any of the sys-' tems above described in con formitywith any system or of the individual oscillating period of the excited system may be performed by the displacement of the elastic means, thus, for instance, of the point of fastening of springs, or of the end of a compression cylinder, by which means the compression space is reduced; or by the control of valves and by a changing of the pressure with which the valves are forced upon their seats, or by a change of the gas mixture, or of the gas or steam pressure, and
