PAY 5 CENTS; LOCK YOUR BICYCLE (May, 1929)
PAY 5 CENTS; LOCK YOUR BICYCLE
A BICYCLE lock which works on the principle of a slot machine has won favor in European countries where the automobile has not displaced the two-wheeled machine in popularity. As shown in the picture at the right, the locking device is attached to the wall of a building. When a coin is inserted in the slot a stout chain is released with which the bicycle is fastened. A key is obtained at the same time.





Didn’t they have bike chains and poles in Europe at the time? This seems like a solution looking for a problem.
Would it be worth it to not have to carry a bike chain and padlock with you all of the time?
