ieved that the harder the link the greater
its tensile strength, but upon actual test this was found to be a fatal
error.

Our leather links are saturated with a mixture of tallow, neatsfoot oil,
etc. This makes them very pliable and increases their toughness, so that
they will stand a strain three times as great as a piece of hard rolled
sole leather.

In manufacturing this belt, the joining together is important. The links
must be accurately assorted as to thickness, and the outer links
countersunk, to admit the bolt. Then the most valuable improvement of
all is our "American joint" (see Fig. 1).

By close inspection you will observe that it is absolutely necessary to
use half length bolts for the width of wide leather link belts.

Examine Figs. 2 and 3. In the latter you will notice one length of bolt
placed on a round faced pulley. That belt must either bend or break, and
in any case it will not give satisfaction; but, on the other hand,
examine Fig. 2; here two half length bolts are used, and ingeniously
joined in the center. It gives just pliability enough to lay the belt
flat upon the pulley. We experimented for some time before perfecting
this important improvement.

We also took out four patents for different methods of joining, but
abandoned them all and adopted the "American joint" system (Fig. 1) as
the most efficient, simple, and reliable. It gives the belt an unbroken
flat surface and is far superior to anything so far introduced for that
purpose.

We have not stopped at _flat_ link belting, but have turned our
attention to manufacturing round solid leather link belting, and believe
that we have almost attained perfection in that line. As the
illustrations clearly show, there is quite a demand for inch and upward
solid round belting, and the difficulty always has been to join such a
belt together. All steel hooks, etc., do not seem to satisfy. This, our
new invention, is so simple that it hardly needs explanation. A belt of
this kind can be taken apart in a short time, and shortened or
lengthened at pleasure.

Now, Mr. President and gentlemen, I shall be glad to answer any
questions in reference to these link belts, or give any further
explanation you may desire.

Question.--Can these link belts be used on dynamos for electric lights?

Answer.--Yes. In England they are used almost exclusively on dynamos.
However, they run only 700 revolutions per minute there, whereas our
slowest dynamo runs 1,
