Adjustment Of Repeated Signaling

[Krion]

Hello! Just a disclaimer, I am vastly unfamiliar with much of the inner-workings of clocks and need some help. I have only built a simple Graham Escapement clock, previously. I need to build a clock that triggers a single signal to occur three times at equally spaced time intervals. These time intervals need to be adjusted after each trial for a total of three trials (we are only given five minutes to adjust). I was looking into striking clocks, but I am unsure of whether you are able to adjust the interval at which it strikes or if it is even doable considering my inexperience. I have also considered adding a lever system that triggers a visual signal, but the dropping weight does not strike the lever with enough force to trigger it. Currently, I am trying to research more into it, but I find it hard to understand a lot of material. A bit of advice would be greatly appreciated!

Does it have to be mechanical? This would be an easy task for a small computer like a Raspberry Pi or Arduino.

Yes, it has to be mechanical. No electrical components are allowed.

What if you take a simple time-only movement and add three radial holes to the center arbor. Tap the holes. Then make three "paddles" that screw into the holes. Those paddles then intersect a lever (that you add) that when lifted by the paddles (three times per hour) trip your signal. Screwing the paddles in and out will alter when the lever is released.
