Abstract
The present invention relates to a motor driven type bell striking device to be employed in electric bells. The device incorporates a cam coupled with the rotating drive shaft of an electric motor, the cam translating the rotary motion of the motor to an oscillating action which serves to impel a piston, the piston then impelling a striking member which is coupled with the base or frame of the bell by a spring. In one preferred embodiment, the previously mentioned spring is a coil spring which wraps around the piston. In a second preferred embodiment, a leaf spring is employed. In both embodiments, the energy of the moving piston is translated into inertia in the striking member. Because the striking member is relatively free floating in the direction in which it moves, a sharp, clear ring sound is made possible with each impact of the striking member.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
