Definitions

  • the present invention relates to a device for converting electric signals into mechanical displacements of a controlled member.
  • the device comprises a continuously rota-ted shaft, a series of juxtaposed wedges slidable transversely of said shaft whereby each relative displacement of one end element of said series of wedges with respect to the other end element in a direction transversely of the wedges produces a corresponding displacement of said controlled member, means for maintaining the wedges of said series constantly one against the other, at least one eccentric driven by the said shaft, a connecting rod for each wedge, pivotally connected to the eccentric and connected through a pair of links to two levers disposed on either side of the said shaft and each adapted to rock in a plane perpendicular to said shaft, means being provided for locking one of the two lovers under the action of one of the said electric signals, so that a single lever of each pair can simultaneously rock and produce a single displacement of the corresponding wedge.
  • Figure 1 is a side elevation partly in section along the line II of Figure 2,
  • FIG. 2 is a section along the line II-II of Figure 1
  • Figures 3 and 4 are similar to Figure l and show the Figure 5 is a section along the line VV of Figure 1.
  • the device comprises a shaft 1 on which is mounted an eccentric 2 to which a series of five connecting rods 3a to 3a is pivotally connected.
  • the shaft 1 is continuously rotated in the bearin 's provided in the frame 4, by a source of energy not shown.
  • the end of each of the connecting rods 3a to 32 is connected by a pair of links 5a to Sc and 6a to dc to two 'levers'la to'7e and 8a to Sc disposed on either side of the shaft!
  • a connectingrod 3 a pain of. links 5 and 6 and a pair of levers 7 and 8, which forman assembly constituting one of the five units of the device, are situated in an elongated aperture 13 formed in a wedge 14.
  • the five wedges 14a to are juxtaposed and bear on the frame 4 and supports 15 ( Figure l) disposed within the latter.
  • a plate 16 formed with elongated apertures 16a maintains the wedges 14a to 142 against the frame 4 and the supports 15.
  • the device comprises in addition five pairs of electromagnets 17a and 18a to 17c and 18e, one for each of the units.
  • Each of the pairs of electromagnets 17 and 18 has a common armature 19a to 1% consisting of three limbs 19 19 19 by means of which two magnetic circuits can be obtained.
  • the five electromagnets are supported by a base plate 20 secured to the frame 4 by means of screws 21. They are so arranged that the levers at 7 and 8 in their lower dead centre position rest on the limbs 19 and 19 respectively of the armature 319.
  • the limb 19 is longer than the other two limbs 19 and 19 and is formed with a. V-shaped notchhaving rounded sides, which is adapted to cooperate with a latch 23 provided on each of the links 5 and 6.
  • the device hereinbefore described operates in the following manner:
  • the thickness constituted of the assembly of wedges 14a to Me between the push rod 24 and the surface 4a of the frame depends upon the position of each of the wedges and may be varied by disprogramme;
  • any change in the position of one or more of these wedges will vary the thickness of the wedging means which they form between the surface 4a of the frame and the push rod 24-, which is possible by virtue of the fact that the latter bears resiliently against the Wedge 14a.
  • the variation of the thickness of the wedging means formed of the wedges will ultimately result in variations of the axial position of the push rod 24, in accordance with a digital programme. It is obvious that the displacements of the push rod may be utilised for the automatic control of the members of a machine.
  • the wedges may be so designed that the variation of the thickness of the wedging means which they form results in accordance with a predetermined binary code, from the displacement, under the action of the levers, of each of the wedges.
  • a predetermined binary code from the displacement, under the action of the levers, of each of the wedges.
  • the conversion of the electric signals into mechanical displacements is effected with a power amplification, since the power necessary for effecting these displacements is supplied by the shaft 1, that is to say, from an independent and continuous energy source, so that the power of the electric signals may be very low.
  • the electromagnets 17 and 18 merely have the efiect of holding the levers 7, 8 fast when they light- 1y touch their armature at zero speed. Consequently, they supply no mechanical work.
