CHRONOLOGY OF INNOVATION
UNITED STATES PATENTS RELATED TO THE TRUMPET
1848 – 2014
VOLUME I: DRAINAGE SYSTEMS
R. DALE OLSON
R. Dale Olson's “Chronology of Innovation” is a series of writings that describes and critiques every United States patent even granted related to the trumpet and other brass musical instruments. Completed, the work will represent the largest writing of its kind related to technology of brass instruments.
The author, R. Dale Olson, has categorized patents according to a system that differs from that of the United States Patent and Trademark Office, so as to be more accessible to musicians.
The first book in this series relates to “Drainage Systems”, or, more prosaically, “water-keys”. Not all fluids accumulated within the interior of brass instruments may be removed using a traditional water-key. Some fluids escape through the valves, leading to a second category of “drainage devices” that are typically located under the valve section, not within the bore.
Prior literature on the subject is restricted to a very few passing mentions concerning this overlooked, but crucial, element within the design of brass instruments. To compensate for this deficit, Olson has created a 158-page book that provides a comprehensive treatment of this aspect of brass instrument design. Provided is an historic underlayment of the issue, a chapter concerning the acoustical concomitants of the water-key, and critiques of each of 51 inventions that have been accorded a United States patent.
Chapters include
- An Overview of Drainage Devices
- A List of All United States Patents Related to Drainage Devices
- Seven Appendices
- A Comprehensive Name Index
- A Complete Bibliography and References
The first United States patent describing a drainage device was an invention by George F. Dallon of Flatbush, New York, on April 21, 1863, and the most recent at the time of publication was by Titus Hutchinson, Sr. of Jacksonville, Florida on December 11, 2014. In the intervening 151 years, drainage devices were invented that included “passive” designs which simply accumulated moisture and “active” inventions requiring the continual operation by the performer. These devices have been located on nearly every part of a trumpet, including one invention that proposed three “discharge valves” or “spheres” positioned on the leadpipe/tuning slide alone!
Only a very few patents address the issue of potential acoustical effects resulting from a water-key, but Olson has explored the subject in detail.
CHRONOLOGY OF INNOVATION: AN OVERVIEW
A SERIES OF WRITINGS BY R. DALE OLSON
“Chronology of Innovation” is a series of writings that describes and critiques every United States patent even granted related to the trumpet and other brass musical instruments. Completed, the work will represent the largest writing of its kind related to technology of brass instruments.
The author, R. Dale Olson, has categorized patents according to a system that differs from that of the United States Patent and Trademark Office, so as to be more accessible to musicians.
Olson has long been recognized as one of the foremost international authorities regarding the design, acoustics, construction, history, and performance of the trumpet. He holds Masters degrees in Trumpet Performance from the University of North Texas, and in Experimental Psychology from California State University, Fullerton. He has lectured at numerous universities, and multiple presentations to the International Trumpet Guild. At the age of 25, Olson became Director of Research for the firm of F.E. Olds and Son, Inc., and has consulted with other makers over a career now covering over seven decades. His professional performing career covered over fifty years. After extensive research and active participation in the field of brass instrument technology, some of Olson’s selected works are now being published. His writings have been referred to as “…paradigms of precision in research and writing”.
The total number of each Volume within the “Chronology of Innovation” series will approximate 10 – 15. Volume I, “Drainage Systems”, was published in 2018, and Volume II, “The Trumpet Mute” is being announced in October, 2020. Volume III, the title and subject of which has not yet been disclosed, is anticipated to be available early in 2021.
Each Volume contains an exceptionally full background of each subject, including the history, design, acoustical implications, and context of the subject patent. The original graphic from the original United Sates patent, with a full description and critique of each invention is provided.
The length of each Volume differs as a function of the subject matter. Volume I, “Drainage Systems” is a 158 page book, whereas Volume II, “The Trumpet Mute” is 441 pages. Subjects that have fewer patents, such as “Cybernetics and Ergonomics”, will obviously be shorter, whereas those with numerous patents, such as “The Trumpet Mouthpiece”, will be much longer.
Musicologists, collectors, organologists, instrument makers, pedagogues, and performers have already begun to acquire this large collection of brass instrument technology.
R. DALE OLSON
Holding and Master’s Degrees in Trumpet Performance (University of North Texas), and Experimental Psychology (California State University, Fullerton), R. Dale Olson brings a new level of expertise to the fields of brass instrument acoustics, design, construction, history, and performance. In 2007, he was named Distinguished Alumnus of the University of North Texas.
Over a period in excess of sixty years, Olson has been co-researcher in brass instrument acoustics and design with Dr. Robert W. Young (then President of the Acoustical Society of America), acoustician William T. Cardwell, Jr., and instrument maker Zigmant J. Kanstul.
He has delivered lectures at numerous Universities and over ten presentations at International Trumpet Guild Conferences.
Although now retired from performance, Olson performed professionally on trumpet for over 60 years in all genres.
Olson was Director of Research for the firm, F.E. Olds and Son, Inc. for nearly a decade, and later consulted on instrument design and testing for firms such as Besson and Kanstul.
His writings are examples of in-depth, deeply researched, precise works that expand the boundaries of the subjects at hand, and are not simplistic restatements of previous authors. Olson’s works typically carry large numbers of references, indices, and appendices to assist in future scholarly investigations.

This product actually lives up to the title of indestructible.
Size: Large (Pack of 1), Product Packaging: Standard Packaging, Size: Large (Pack of 1), Product Packaging: Standard Packaging
This is the only toy I've had which my dog hasn't destroyed in minutes. I have had a few others that will at least last a few months, but Kong extreme has held up over the years. I like the fact that I can stuff it with treats, bits of other "indestructible" toys and seal it up with peanut butter, then pop it in the freezer to give her an extra 15 minute challenge. I have a couple so I can clean one while she's busy with the other. This size seems to be the best for a ~90lb. dog, the large end being roughly the same size as a tennis ball, which she loves as well.

Great product but choose a size or two up
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Nice quality toy for long lasting and engaging play! One star docked for the sizing—I don't usually expect to need an xl anything for my 45lb border collie but he cant even fit his canine teeth into the large size to ease the jerky reward out in "hard" position but "easy" position he doesn't even tough the toy just grabs the jerky. Got an XL and it has been great for the jerky both easy and hard positioning. The larges I keep around for liquidy and frozen treats to keep the mess contained and they work very well for that.

Truly for Aggressive Chewers
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Excellent product for aggressive chewers. The black Kong doesn't last forever BUT it is the most reliable toy I've used with my 60# pitt mix. I've returned so many toys that were advertised as for this girl's level of enthusiasm that I no longer buy anything else.

Excellent tug toy!
Size: Large Triple, Size: Large Triple
My dog had this set of 3 interlocking rings for 7 years and they finally broke. I was so happy to be able to get a replacement set that is just as durable as the original! Just ask our Gretzky to, “get your rings” and she knows exactly what to find. She can tug these for an hour and not lose interest. She loves them. They are the perfect size for her to grab comfortably and for her human playmate to hold onto the other ring in opposition. Gretzky is half Boxer, about 85lbs and all muscle. For her first set to withstand years of tugging without breaking was surprising but they’re made well and as long as you don’t allow your dog to just sit and chew them, they’ll give you years of tugging playtime!
