Abstract
A motor actuated bell comprises a motor having a drive shaft and a cam means connected to the drive shaft. The cam means is engageable with an elongated hammer intermediate the opposite ends thereof to intermittently move the hammer away from a gong against the bias of an urging means. When the cam means becomes disengaged from the hammer, the hammer is moved along its axis into striking contact with the gong under the action of the urging means.
