Frame-Plate on which is placed the Train of Wheel-Work i, 2, 3, 4. which is much the fame as in otherClocks, and is governed by a Balance and Regulator asin them. But for a Spring and Fusee, there needsnone in this Clock, their Effects being otherwise an-*swered, as we shall fee.

41. In this Machine the great Wheel 1 is placed, inthe Centre, or upon the Axis of the Movement, andthe other Wheels and Parts towards one Side, whichtherefore would prove a Biafs to the Body of the Clock,and cause it to move, even on a horizontal Plane, forsome short Distance; this makes it necessary to fix athin Plate of Lead at C on the opposite Part of theHoop, to restore the Equilibrium of the Movement.

42. This being done, the Machine will abide atrest in any Position on the horizontal Plane HH ; butif that Plane be changed into the Inclined Plane DE,it will touch it in the Point D ; but it cannot rest there,because the Centre of Gravity at M acting in the Di-rection MT, and the Point T having nothing to sup-port it, must continually descend and carry the Bodydown the Plane.

43. But now if any Weight P be fixed en the otherSide the Machine, such as shall remove the Centre ofGravity from M to the Point V in the LineLD, whichpastes thro’ the Point D, then it will rest upon the In-clined Plane, as we have shewn in the Cafe of theRolling Cylincbr ; for this Instrument is founded on thefame Principle.

44. If now the Weight P be supposed not fixed, butsuspended at the End of an Arm, or Veftis ; whichArm or Lever is at the fame T me fastened to a Cen-tral Wheel 1, moving on the Axis M of the Machine,which Wheel by its Teeth shall communicate with theTrain of Wheels, (jfc. on the other Side ; I fay, inthis Cafe if the Power of the Weight P be just equal tothe Friction or Resistance cf the Train, it will remainmotionless all one as before when it was fixed ; andconsequently the Clock also will be at rest on the In-clined Plane.

45. But supposing the Weight P has a Power fupe-
