Counterweight shell for clocks

Abstract

A counterweight shell for clocks includes an elongated body of cylindrical shape, open at one end and having a bottom wall as an integral part of the body and having a central aperture. A rod with its opposite ends threaded is axially nested within said body with one end projected through said bottom wall, and receives a nut threaded thereon which bears against said bottom wall. A top cap having a central aperture and an integral annular flange is nested over the open end of the body, with the other end of the rod projected through said cap. A hook having an apertured shank receives and is threaded over the rod other end to retainingly engage the cap. The bottom wall has a central portion which is axially indented into the body for completely enclosing said nut. The body, bottom wall and cap are of aluminum, the body and bottom wall being drawn or extruded. The outer surface of the body, bottom wall and cap are annodized to a color simulating brass. The invention further includes the method of making such counterweight shell which comprises deep drawing or extruding an aluminum disc to form an elongated body of cylindrical shape open at one end and having an integral bottom wall. A further step includes the stamping of aluminum cap to have an annular flange. A further step includes brushing the body, bottom wall and cap and a final step includes annodizing the body, bottom wall and cap to a color simulating brass. The shell and cap may be made of brass.
