Definitions

  • a pin pallet for a timepiece escapement comprises a pallet plate stamped from thin sheet material and having a pair of laterally spaced openings, a pin member comprising a U-shaped wire being bonded to said plate with its arms extending through said openings to constitute the pins;
  • FIG.1 A first figure.
  • the diameter of 0.25mm of the part which is driven into the pallet generally is greater than to the thickness of the pallet, so that the depth of the hole in the pallet is smaller than the diameter, which increases the uncertainty of the correct position of the pin in respect to the plane of the pallet.
  • a different known construction describes a pin-pallet made from metallic wire, which, with respect to the present invention, leads to a reduction of the noise of a time piece, by using a pallet with elastic arms. This has the disadvantageof a much more complicated and expensive fabrication than in the case of the execution proposed by the present invention.
  • the present invention describes a flat pallet plate having two laterally spaced openings constituted by holes or notches in the arms of the pallet plate, and the two pins which are fixed inthose holes, openings or notches consist in the bent parts of a metallic wire.
  • the pallet consists in a thin blanked plate 1 and a straight piece of wire 2 bent into U-shape and whose extremities or arms 3 and 4 are at right angles to the bight portion and constitute the pins. These extremities are introduced through openings constituted by holes in the pallet and which are of slightly greater diameter that that of the pins.
  • the wire 2 is fixed by bonding such as soldering or cementing, for example its bight portion, to the adjacent side of the pallet.
  • a wire, having a bight portion 9, is soldered into notches 10 in the pallet 1" the pins being constituted by the extremities 11 and 12 of the wire 9, which are bent at right angles.
  • a pin pallet for a timepiece escapement comprising a pallet plate blanked from thin sheet material having a pair of laterally spaced openings therethrough;
  • a pin member constituted by a U-shaped wire including a bight portion of a length to span the distance between said openings and substantially parallel arms substantially perpendicular to said bight portion;
  • said pin member being mounted on said plate with its arms extending through said openings to constitute pins and its bight portion engaging one surface of said plate, and
  • a pallet according to claim 4 wherein theex tremities of the wire which form the pins, are pressed-in at an angle of said polygonal openings of the pallet by the spring effect of the wire, before they are fixed definitively to the pallet by bonding.
  • said openings comprise notches in the edges of said plate
  • said means bonding said pin member to said plate at said notches.
  • a pin pallet for a timepiece escapement comprismg a a pallet plate blanked from thin sheetmaterial having a pair of laterally spaced openings therethrough: a pin member constituted by a U-shaped wire including a bight portion of a length to span the distance between said openings and substantially parallel arms substantially perpendicular to said bight portion; the thickness of said plate being less than that of said wire, a
  • said pin member being mounted on said plate with its arms extending through said openings to constitute pins and its bight portion engaging one surface of said plate, and
