Definitions
- Fig. 2 is a transverse section of the said pillar-plate and the barrel for containing the mainspring, such section being taken through the centers of the said plate and barrel.
- FIG. 3 is a top view of the nlain gear, the retaining-power ratchet and pawl, and the winding or barrel-arbor ratchet and pawl.
- Fig. 4 is a top view ofthe stop-works.
- Fig. 5 is a verticalsection of them and the bridge.
- Fig. 6 is a top view of the pillar-plate, a-ll the parts of the different gures being drawn on a scale three times the usual size.
- A denotes the pillarplate and B the barrel for containing the inainspring, the latter not being represented in the drawings.
- This barrel is formed with a projecting flange, a, for the purpose of enabling it to be fastened to the pillar-plate, into and through which it extends, as shown in the drawings, the said pillar-plate being formed with a round hole havin g a diameter equal to that of the barrel and for the reception of the barrel.
- Fig. 6 I have shown a top view of the pillar-plate, such also representing the capplate b of the barrel.
- This cap-plate is made in one solid-piece with the barrel, and both are secured in place by two screws, c c, extend.
- C is the winding-arbor, which steps or is pivoted into the cap-plate b, and turns in a bridge, d, arranged parallel to and with respect to the pillar-plate, and fas tened to it by posits.
- the stop-wheels E F are placed in sunken recesses made in the bridge-plate, as shown at d c.
- G is the main gear, which is arranged so as to constitute a cap or bottom to the barrel.
- the winding-arbor and main wheel are com bined in essentially the same manner as the main wheel and common fusee of a watch, excepting that with regard tothe part M of the winding-arbor which is within the barrel and around which the mainspring is coiled.
- the thickness of the part M should be such as torbring the main wheel just out of contact with the rim of the barrel, so that the said main wheel may turn freely and serve as a cover or bottom to the barrel.
- Such barrel is so supportedV by such plate as to entirely prevent it from being burstopen by such a recoil of the mainspring (an accident which frequentlyhappens) when the barrel rotates and is arranged entirely outside of the pillar-plate.
- This ⁇ ar rangement also enables the watch to be made thinner, comparatively speaking, as while the watch is being wound up the winding-arbor rotates in one direction, and in the opposite hour-hand of the watch.
- FIG. 7 is an inside viewof the main gear- Wlieel, showingthe retainingor,,maintaining power spring, et?, as ⁇ arrangedfin, an annular recess., b2,formed in thel said wheel.
- the loose end of the spring is shown as provided with a small projection, 02,'which, when the wheel is in place, extends into a corresponding hole made in the rctainin g or maintaining power ratchet, H, and thus connects such ratchet with the said spring.
- the retainingpower spring receives its force directly from ⁇ the barrel-arbor around which the inainspring is coiled.
