Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1897 edition. Excerpt: ... Hammer--Electric Insects The Incandescent Lamp. The Electric Dancer. This amusing toy originally was produced to be operated entirely by band. Tbe electrical modification is based upon the principle of the vibrating bell, and needs but a short description. The cuts show one construction very clearly. A box contains the motive mechanism. This consists of an electro-magnet with a soft iron armature carried by a spring. A. wire from the battery goes directly to the magnet. The other terminal of the magnet connects with the armature spring at L1. The other end of the spring is bent at right angles at Ls, and carries a platform on a support L3. This is the dancing platform. A contact spring, S S, is carried by the armature spring. A contact screw, C, is adjustable as regards its contact with the spring S S. From it a wire runs to the binding post, B, to which the other battery wire is attached. The magnet may have as cores round iron bars f inch in diameter, 1 inch long, and wound to 1 inch diameter, with No. 26 silk covered wire. The action of a current on such mechanism is to keep the platform in constant vibration, which may TEE ELECTBIG DANCER.?5 be regulated and modified over quite a range of action by the screw, C.

When a current passes, the figure begins to dance, and keeps it up as long as the battery supplies enough energy. Another way of working it is to make the figure do the making and breaking of the circuit. For this end, the binding post, B, should be connected to the curved suspension-rod, instead of connecting with the contact screw, C.
