One of the best known inventions of Tom Bass was a bit that did not irritate the mouth of the horse.  Tom's opinion was that many horse problems were related to the wrong bit being used.  Below is an actual Tom Bass Bit and a drawing of a horse with one.

Tom developed the new gentle bit but refused to patent it.  However, Tom did sell the bits as shown by the 1900 ad below.
