1. Door Bell's Pull Handle and Interior view

Several years ago we visited the Breakers, Vanderbiltís family's estate in Rhode Island. I remember seeing a handle mounted in one of the rooms and at first could not make out its purpose. After tracing the wire that ran from it, I discovered that it rang a bell in a kitchen several floors below.

Ever since seeing that bell, I've wanted to build one like it that would be directly wired and would play rhythmically at least 7 times for each string pull. I also wanted to design a solution that would not rely on the wire tension strength of the pull. The solution that I came up with is based on a traditional pulley-based bell and a cam driven oscillator. This combination enables uniform activation and eliminates the possibility of the user over- or under-pulling. The linear pull handle motion is translated to the bell's angular motion via a rotating gear and a spring-controlled rod.

4. A Push Rod Door Bell

This manually activated exterior door bell uses a push rod and two springs. The copper accordion spring transfers the motion from the exterior handle while the curved spring restricts the movement of the bell. The spring supporting the bell is made of an old hacksaw blade.


 

    

5. Self Circulating Water Fountain

The water fountain is based on a self-circulating system. The basin contains water and has an embedded water pump (hidden inside the peacock). One side of the curved tube over the basin is connected to the pump. The tube contains a number of holes (just over the glass beads) that act as the discharge orifices.
