  • the escapement wheel 88 is, in turn, engaged with the pallet pinion 93 which is journalled within aligned openings 94, 95 in the dial plate and an inwardly offset tab 96 of the train plate.
  • r1 ⁇ he speed of rotation of the escapement wheel 88 is controlled by a balance unit 100 mounted within openings 101, 102 in the dial and train plates, a jewel screw 103 being provided for adjusting the end shake of the balance unit 100 during the assembly of and later adjustment of the time piece.
  • the escapement mechanism thus controls the rate of rotation of the barrel 40 by the main spring 41 which, in turn, limits the speed at which the barrel wheel 39 rotates the cannon pinion 34 and the minute and hour hands.
  • the balance unit and escapement control the speed at which the barrel gear 64 is permitted to rotate the sweep second hand 46, di'- rectly, through the engagement of the third wheel 50 with the sweep second pinion 48.

  • the detent 112 at the opposite end of the click 109 extends-upwardly through an opening 114 in the train plate 56 and is in ratchet engagement with the ratchet wheel 72, thus preventing backward rotation ofthe ratchet wheel 72 when the main spring 41 is wound.
  • a stem block 120 is shown to be mounted between the facing sides of the dial and train plates by means of a bolt121.
  • One end of the stem block 120 is bifurcated and includes a pair of spaced apart parallel arms 122 that have aligned openings 123 within which avstem 125 is rotatably and slidably supported.
  • a drive pinion slidably carried upon a flat 126 of the stem 125 is rotatably supported within the slot 128 between the bifurcated arms 122.' Because of the non-circular opening through the ⁇ drive pinion 127 and the correspondingly shaped flat portion 126 of the stem, the stem may be moved axially, ⁇ while being drivingly connected to the drive pinion. Both the dial and train plates are provided with aligned slots 130, 131 through which the diametrically opposite sides of the drive pinion 127 are received.
  • a winding wheel 133 rotatably supported upon a shaft 134 that extends through an arcuate slot 135 inthe train plate is carried upon the free end of a winding lever 136 that has an opening 137 at its opposite end for rotatably receiving one of the stake posts 70b.
  • This winding lever is mounted on the netrior side of the train plate and a winding wheel 133 is normally urged into meshing engagement with the ratchet wheel 72 by a spring extension 139 that abuts againsta downwardly struck stop portion 140 of the train plate.
  • the adjacent side of the drive pinion 127 is in constantly meshing engagement with the winding wheel 133, whereby rotation of the stem 125 in the normal winding position shown in FIG.
  • the setting lever 14S having a spring portion 148, is also pivotally mounted upon the stake post 70b adjacent to the inside surface of the face plate 27.
  • the free end of the setting lever 145 is provided with a follower tip that is in sliding engagement with a circular cam 152 secured upon the stem 125.
  • the came152 engages the follower tip 150 and rotates the setting lever 145 against the action of the spring portion 148 that is in abutment at its free end with another stake post 70a.
  • a setting wheel 155 rotatably carried upon a shaft 156 of the setting lever 145 is drawn intoy meshing engagement with an intermediate setting wheel 158 carried upon the shaft 159 and which is in constantly meshed engagement with the minute wheel 3-6.
  • rotation of the stem 125 in the outwardly extended time-setting motion shown in FIG. 16 permits the setting wheel to rotate the intermediate setting wheel 158 to effect rotation, of both the minute and hour hands through the v minute wheel pinion, 37, the cannon pinion 34, and associated minute and hour wheels 36, 34.
  • Outward movement of the stem 125 is limited by a stop cock'153 carried upon' the train plate and projecting into the path ofmovement of the cam 152.
  • the trainplate is also provided with a terminal 161 for one end of the hair spring associated with the balance unitv100, and with a pivotally mounted time adjust-ment plate 162 connected to the opposite end of the hair spring, in a well known manner.
