George Riblet, Patent 1021890
granted April 2, 1912 "Slide Trombone"
This is the patent referenced on the engraving of early
trombones. It covers several design features, including an improved
tuning-in-slide mechanism and extended stockings. It is unclear what,
if any, relationship there was between Mr. Riblet and F. E. Olds.
Reginald Olds, Patent 1821397
granted September 1, 1931 "Piston Valve for Wind Instruments"
Reg Olds' first patent; it covers the spring and valve
system used in some early Olds trumpets and cornets.
Reginald Olds, Patent 2021323
November 19, 1935 "Stationary Inner Slide Tube for Trombones and
The original fluted slide patent, using longitudinal grooves drawn into the surface of the inner slide. This design
would have been difficult to produce (as mentioned in the introduction
to patent 2106327). At one point, I did not think that it had ever
actually been used, but it was apparently produced for a short period
of time, as evidenced by this
Patent 2106327 granted
January 25, 1938 "Stationary
Inner Slide Tube for Trombones and Similar Instruments"
An improvement of the design in patent 2021323, using a
"duo-octagonal" cross-section in place of the earlier fluted version. Olds applied for this
patent on September 1, 1936 - less than a year after receiving
the patent for the fluted slide. Slide tubes of this pattern were standard on Supers and Recordings, but they pop up on other
models (like this
Standard) on occasion. There's a rumor that Olds never actually
made duo-octagonal tubes after the move to Fullerton, but was simply
working through a large stock of tubes drawn prior to the move from Los
Angeles. A obscure point of terminology: since the term "fluted" actually refers to a grooved surface, its use to describe tubes made under this patent is not technically correct.
Reginald Olds, Design Patent 110493
granted July 12, 1938 "Trombone"
The trademark one-piece streamlined braces used on the
Olds trombone. Variations on this design can also be found on the Recording and Studio models.
Reginald Olds, Patent 2260723
granted October 28, 1941 "Piston Valve for Musical Wind Instruments"
A grooved valve design, simlar in concept to original
slide covered by patent 2021323. As with 2021323, I have neither seen
nor heard from anyone who has seen a valve using this design.
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.
