I Have a growing collection of metronomes.
Below is a sample of what is in the collection.

A few unusual metronomes
Pinfold's Patent Metronome
This metronome dates back into the 1800's. This metronome uses no outside mechanical mechanism. You put the pendulum in motion and then watch it. When the oscillation become to short you give it another "push". Here it is in it's case.
This picture shows the movable weight that adjusts the speed of the pendulum.
Here is the metronome set up and ready to go. There is no sound with this metronome. It is nothing more than a pendulum with an adjustable weight to control the oscillation speed.
The radio sized cabinet of the Trinome. Metronome operates on 117 VAC. This is probably one of the most unusual metronomes available. White spots on black cabinet are dust.

The speed lever engages speeds ranging from 19 to 29 revolutions per minute. The three beat-levers (bell, tick, tock) engage beats numbered 1 to 8, singly or in combination. It is possible to get three totally unrelated rhythms going at the same time. They will have beat one in common.
The rear view of the Trinome showing the various gears and cams necessary to get the different rhythms and tempos.
This is a model 8380. Wooden case is 6 1/2"x5"x3"
This metronome also gives four pitches; F, A, Bb and C in addition to being a full function metronome. Unit operates on two 9 volt batteries.
Rhythm Trainer RT-10
Here is another unusual metronome. Rather large at 12" wide, 5" high and 2 1/2" deep. Huge 5" dial to select tempo. Does duple or triplet rhythms. Also gives adjustable "A" and "Bb" pitches.
Now here is undoubtedly the most unusual metronome in my collection! A Tel-A-Tempo. This mechanical monstrosity has a motor, a strange disk speed control, two "door bell" type tone bars and a whole bunch of other electronic "stuff". It actually works with lights flashing and tone bars sounding. Bet you won't see another one of these in a long while!
The label, sure looks as if they made more than one...
A view of the insides. the portion on the right is the top/sides/back cover. yes there are lights on the back also! The silver block is the resonator to one of the tone bars (the bar is mounted upside down on this resonator block).
Here is a close up of the tempo control. A motor under the gray disk spins the disk. A rubber tired wheel on the other side of the reddish block contacts the wheel and depending on where the wheel contacts the disk, the tempo is derived. The reddish wheel on this side of the disk is the contactor wheel. One revolution of this wheel gives one electrical impulse to the lights and tone bars.
