Definitions

  • MOVEMENT REGULATING ARRANGEMENT Filed Jan. 23, 1957 2,941,417
  • the invention relates 'to a movement regulating arrangement with an oscillating system comprising a permanent magnet and a spring and controlling a magnetic escapement wheel.
  • Such movement regulating arrangements are described, for example, in the Clilford German patent specifications Nos. 809,420; 812,615; 914.837-and United States Patent 916,160.
  • the present invention deals with improvements in the construction of the magnet as well as the whole arrangement of the movement regulator and the design of the adjusting and regulating means.
  • the invention has for its object to produce a movement regulating arrangement in the form of an independent group of parts (so-called escapement).
  • the oscillating system composed of a magnet and a spring, is fixed on the frame of the movement regulator or the train of gears coordinated thereto by means of a support which, according to the teaching of the Clifford German patent specification No. 809,420 is located approximately in the centre of gravity of the oscillating system or near an axis which passes through the centre of gravity.
  • a support which, according to the teaching of the Clifford German patent specification No. 809,420 is located approximately in the centre of gravity of the oscillating system or near an axis which passes through the centre of gravity.
  • the support on the bearing frame of the movement regulator so that it can turn about an axis extending parallel to the axis of the escapement wheel.
  • the oscillating system can, according to a further feature of the invention, be accommodated together with the escapement wheel and also at least one gear wheel connected up in series therewith, or preferably two such wheels, in a special movement frame composed of two movement plates and spacing posts, the movement frame being provided with connecting means for mounting on a movement frame (time movement) comprising the driving spring, the remaining parts of the chain of gears controlling the movement regulator, the hand driving gear and, if necessary, other gears such as for example striking or alarm gears, in such a manner that the movement plates lie in pairs approximately in the same planes.
  • Magnet movement regulating arrangements of the type here coming into question are somewhat sensitive to fluctuations in power. This applies particlarly to 8- day timepieces.
  • a power compensating device known per se can be fitted in the chain of gears between the driving spring and the movement regulating arrangement; a suitable device is shown in the Clifford German patent specification No. 875,592.
  • Fig. 1 is a perspective view of the permanent magnet
  • Fig. 2 shows in a similar View to Fig. 1 the bridgeshaped passage safety member
  • Fig. 3 is a side elevation of the movement regulating arrangement with the front plate of the movement removed, and
  • Fig. 4 is a top plan view of Fig. 3.
  • the permanent magnet as a whole is designated by 10 and composed of two congruent laminae 1-1 and 12.
  • the magnet body 10 is of substantially U-shape, the ends of the pole arms 10a and 10b being directed inwards and form opposite pole end faces 10c and 10d.
  • the magnet laminae have two punched holes 10e.
  • Dovetailed recesses 10] and 10g are formed in the ends of the magnet arms 10a and 10b.
  • These recesses serve for receiving rivet lugs 15a and 15b formed on a bridgeshaped non-ferrous part designated as a whole by 15, which part is riveted to the magnet lamina packet and serves to catch with its curved middle part 15c the escapement wheel 16 by its pole teeth 16a, when it is about to fall out of step with the oscillating system composed of the magnet and oscillating spring 13, for example in the event-of a jolt.
  • the oscillating spring 13 is provided with a tongue 13a by means of which it is fixed by a screw on the support 17, the support consists for example of section brass and has a turned pin 17a by means of which it is riveted to the movement plate 19 with an interposed friction washer 18.
  • the support has a transverse bore 17b to enable the introduction of a long pin from the side, with the aid of which pin the support can be adjusted very accurately in relation to the escapement wheel 16 for regulating the distance of penetration of the magnet poles 10c and 10d.
  • Movement regulating device with an oscillating system comprising-apermanent magnet and a spring for '3 controlling an escapement wheel
  • the permanent magnet being U-shaped in plan and is composed of at least two at least partly congruent laminae constituted by a material in the form of layers, said layers having recesses within one edge thereof, and a reinforcement member fitted on the magnet and secured in the recesses and co operating with an escapement wheel, the permanent magnet having its end faces opposite each other, the reinforcement member being composed of non-magnetic bridge provided with depending lugs by means of which it is secured in the recesses.
  • Movement regulating device in which the recesses each have a swallow-tail configuration.
  • a magnet for use in a magnetic escapement mechanism for an electric clock comprising a U-shaped member in plan composed of at least two at least partly congruent laminae in the form of layers, each layer having' recesses within one edgethereof, and a bridge rein forcement member secured in the recesses and composed of a non-magnetic bridge provided with depending lugs by means of which it is secured in the recesses.
  • a magnet for use in a Clifford magnetic escapement mechanism comprising'a U-shaped member in plan composed of at least two at least partly congruent laminae in the form of layers with each layer provided with at least two recesses in the outer ends of the legs of the U, and a bridge reinforcement member secured in the recesses andcomposed of a non-magnetic bridge material across the outerends of the legs, said bridge being secured in the recesses by means on the bridge.
