Book 3 — Cannon-Shell Dinner Bell

Reading edition

Being called to dinner by the stirring peal of a bell made of a cannon shell is a novelty in use in Toronto. The bell shown in the sketch was made of a 3-in. brass shell, and when struck with a gavel gives out tones that penetrate throughout a large house.

Illustration from The boy mechanic, book 3: 800 things for boys to do

Its Tones Penetrate a Large House

The cap piece was removed at A, and an eyebolt fastened in place with a nut on each side. The gong was suspended from a wall bracket made of a band of brass fastened to the wall.—Contributed by James B. Noble, Toronto, Canada.
