It is a very cunning mechanical appliance,
too, and has found favor to a great extent in England, where several
thousand heads of drawing and speeders are already supplied.
This invention was exhibited at the Centennial in 1876, although in a
somewhat crude state. Since that time it has been materially improved,
and mechanically is very nearly perfect now. Many attempts have been
made to apply a stop motion, which should be quick in its movement and
accurate in its result, to carding engines or the card, not one of
which, until the application of electricity, was worth the time spent in
putting it on. With the electric motion, however, all this is changed,
and the electric attachments are not of necessity so fragile as to be
un-mechanical or to be not practical. The advantage has also been
taken, in a mechanical way, of using cotton as one element, and, being
non-conducting, so that no trouble shall arise from contact with the
working parts of the electrical apparatus with the cotton itself.
To take into consideration all the possibilities that exist from the
railway can to the front of the fine speeder is not needed by the
practical reader, and would be useless to any other. The principle of
this invention is the supplying of a magneto-electric current from
a small magneto-electric machine attached to the card, speeder, or
whatever machine it may be applied to which generates the current, and
this machine is driven by a small belt from the main driving shaft.
