The Ryder Self-Locking Meter Box.
Among the advantages of the Ryder self-locking meter box may be mentioned that the opening in the center of the top for admitting the key is closed automatically by a lead plug which will not corrode and which prevents dirt, water and cold air from entering the box. The key for unlocking the top is of such a shape that it serves as a handle by which to lift the same. 1’he key cannot be removed without leaving the top in a locked position, with absolutely no chance for the meter reader to leave the box open. Being a quick box to lock and unlock, it saves much time for the meter reader. Owing to the shape of the key and to the fact that the locking device is not visible from the top, it is a very hard box to unlock without a special key made for that purpose, so that boys or unauthorized parties have the greatest difficulty in tampering with the meter—a point of much importance. It is also as durable as any box made, in addition to all of its other advantages. The guard underneath serves as a protection to the spring when the top is held upon the pavement in reading the meter, and also makes it impossible to force the spring down far enough from the top to break it, as only enough room is allowed to unlock the box freely. Every box is finished and fitted with great care, so that satisfaction may be guaranteed users. The Ryder self-locking meter box and Morris patent meter box top are made by the Clarksville Foundry & Machine Company of Clarksville, Tenn.
