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.

Asurion worked as intended.
After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim.
The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount.
While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss

Don't waste your money - these people will not help you
On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number.
Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again.
Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned.
It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact.
At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.

Asurion is AWESOME!
Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION!
I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered!
Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion!
The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place.
Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄
Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone.
This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair
specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage.
But, I can live with that.
All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously!
Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.
