granted April 2, 1912 "Slide Trombone"
This is the patent referenced on the engraving of early Olds
trombones. It covers several design features, including an improved
tuning-in-slide mechanism and extended stockings. It is unclear what,

The first fluted slide patent, using grooved inners. This design
would have been difficult to produce (as mentioned in the introduction
to patent 2106327) and may have never seen production . I've never seen an example, nor have I talked to

read through the patents, you might notice that all of the Olds patents
were filed by the
legal firm of Hazard and Miller. In addition to being involved with
the Los Angeles Tool Works (and thus Frank Olds'
one-time employer/business associate), Henry T. Hazard
was a significant figure in the history of Los Angeles, having served
as both City Attorney and Mayor (1889-1892). In 1887 he built Hazard's
Pavillion, a 4,000+ seat auditorium that was, at the time, the largest
structure of its kind in the city and was the predecessor of the
structure that came to be known as Philharmonic Auditorium, the home of
the Los Angeles Philharmonic Orchestra from 1920 until the early 1960's.
