BEAT OF THE PENDULUM.

A Device for Keeping It Plumb mid True at AH Times. The Illustration represents a leveling device adopted for attachment to a clock mechanism to control the pendulum and verge, whereby they will be iopt plumb, Irrespective of the frame carrying the clock mechanism proper. The clock mechanism may he of any desired construction, and the verge wheel shaft is Journaled In the frame at the back and In a bracket projected at the front, each bearing being formed with a boss having an integral stud, anu on the studs being pivoted the upper members of a U-shaped frame from which depends a weight. The front member of the U-shaped frame is at all times in front of the verge rod, while the rear member is straight. On the Inner fa’ce of the front member is pivoted a block in which Is Journaled one end of the verge spindle, its opposite end being held In tbo usual jprlng. The verge is thus carried by the weighted swinging frame, and the pen-

iulum ford at its upiifer end, after passtng througli the" verge, is swtirfed jn the usual manner to a poet, which Is also secured to .the back of the forward member of the weighted frame, whereby both the pendulum and the verge are kept perfectly plumb. The device is very simple and inexpensive.
