Cycling Patents of Yesteryear: No. 7 – Evan S. Connell Jr’s
Bicycle Attached Toy Machine Gun, 1951
The invention of one Evan S. Connell Jr of Santa Cruz California, a bicycle mounted toy machine gun that could be aimed in any direction along the horizontal and vertical plane, and which, in a variant of the playing card and peg, used a leaf spring connected to the gun trigger to make the firing noise of the machine gun, the spring running against the spokes when the trigger was pulled.

E. S. Connell Jr’s bicycle mounted toy machine gun. US Patent 2,667,720
The difference was that the playing card attached to the spokes made a constant sound every time
you rode the bike.
With the “toy machine-gun” attachment”, you could control the sound by pulling on the trigger which was
connected to a spring that was near the spokes. Squeezing the trigger would cause the spring
to touch the spokes creating the sound.
I used an old playing card on my bike to create the sound. But in my case, I was relating it to the
sound of a motorcycle.
Not that it sounded like a motorcycle...but for a kid it was cool!
It’s on the same principle like the “Persons Majestic Bicycle Siren”
But instead of a spring, you use a chain attached to the handlebars.
Pulling on the chain would move the roller towards the wheel causing the spinning
of the mechanism to create a “siren” sound. The faster you went the louder the sound.
