Such clocks hardly ever bring the full sound out of the bells ; because, in order to do so, the weights would have to be so heavy, and the clock so large, as to increase the price considerably. A good bell, even of the ordinary thickness, which is less than in the Westminster bells, requires a hammer of not less than ^th of its weight, rising 8 or 9 inches from the bell, to bring out the full sound ; and therefore, allowing for the loss by friction, a bell of 30 cwt, which is not an uncommon tenor for a large peal, would require a clock weight of 15 cwt., with a clear fall of 40 feet ; and either the Cambridge quarters on a peal of ten, or the Doncaster ones on the 2d, 3d, 4th, and 7th bells of a peal of eight, will require above a ton, according to the usual scale of bells in a ring ing peal (which is thinner than the Westminster clock bells). Very few clocks are adapted for such weights as these ; and without abundance of strength and great size in all the parts, it would be unsafe to use them. But if the striking parts are made to wind up every day, of course }th of these weights will do ; and you may have a more powerful clock in effect, and a safer one to manage, in half the com pass, and for much less cost. Churches with such bells as these have always a sexton or some other person belonging to them, and in attendance every day, who can wind up the clock just as well as a clockmaker s man, The going part always requires a much lighter weight, and may as well go a week, and be in the charge of a clock- maker, where it is possible.}|undefined} 1em 1em 1em 1em 1em 1em 1em
