latter. The weight is usually hung inside, as the centrifugal foice
of a rapidly revolving carrier tends to prevent an outside carrier
dropping quickly enough to prevent kinking when the thread
slackens. The weight is thus also more protected from dirt, but
this arrangement makes the threading somewhat more troublesome.
Fig. 11 shows a carrier without bobbin, but when a bobbin is placed
on it the thread is first run through the eye near the center of
the standard, then through the stop-motion eye, then up through the
eye at the top of the standard, down through an eye in the lever e,
through the tension-weight eye, and then through the eye at the top
of the hollow spindle, whence it goes to the braid former. This
makes a total of six eyes to be threaded. On both styles the short
lever at the top is arranged so as to be lifted clear of notches in
the top of the spool by the tension of the thread, but when this
tension ceases the lever drops into a notch and prevents the bobbin
continuing to unwind. Fig. 11. Fig. 12. Fig. 13. Fig. 11.--Vertical

ordinary braid two gears are of course the least possible number
that can be used. On large lace machines there may be as many as
60. In making the simple "soutache" braid previously noted the horn
gears at the end are always made with an odd number" of teeth and
the middle gears with an even number of teeth. The reason for this
is readily seen, as the end gears have to carry each bobbin
completely around and start it in between two other bobbins on its
return course. The...
