Dear Members:
This post was deleted by the Admin of WWA for no apparent reason nor warning...I strongly believe that I am being unbiased and courteous but most important, shooters of all disciplines including BR should know the truth or at least hear this side of the story for making their own conclusions and I am re-posting it in this forum.
The purpose of this information is the opposite to being controversial and is only a reconciliation of what has been said in the past and about muzzle devices/tuners and their inventors...
It will be very hard if not impossible to determine who actually invented “Muzzle Devices” (tuners included) because if we trace these artifacts around the US Patents Office, we find registers that go back to the late 1800’s and even before then…
One thing is a fact: Muzzle devices WERE NOT invented in the 1990’s...But we can say that they have been successfully used in Rimfire rifles in later years and that Bill Calfee has indeed done much research in stabilizing a barrel with the use of these devices and with other methods.
Bill’s claim of being “THE INVENTOR” of muzzle devices in the 1990’s I believe is just an INTENTIONAL OVERSTATEMENT to emphasize that he has been a great contributor to its success in .22 RF BENCHREST, this is very true and nobody can contradict this fact but somebody not understanding Bill’s overstatement may misjudge him and will see him as an IMPOSTOR and accuse him of PLAGIARISM...Accusations like these is what motivated me to start this thread.
By researching the USPTO office we find that It is a fact that neither Bill, nor anybody else we know is or was the inventor of muzzle devices and BC couldn't credit himself as the SOLE inventor simply because he has no invention/patent record, because I believe that he actually doesn't mean the literal context of his claims, and lastly and more important is because there are over 100 years of patented muzzle devices before he was even born...It would be just insane and ridiculous for anyone to pretend making such claims believable and I don't think that BC falls into this category, but only him and time will tell us what is going on...
In reality we all know what Bill Calfee means behind his statements and he DEFINITELY deserves much of the credit for these devices being used successfully in Rimfire Benchrest shooting, but we all know that he did not INVENT them.
A specific tuner for .22 RF was designed in 1990 (Years before Calfee's development era) by a couple of Swiss inventors (Bossard and Pesek) patent number 4913031, the device consists of a weight with vent porting and a lockable ring, this device has been used by Feinwerkbau, Steyr and Anschutz for decades and after improving it, it is currently also used by Swiss Bleiker and Grunig and Elmiger for their Olympic ISSF rifles very successfully...The device looks similar to a Harrell tuner with a Non-Funtional integral venting system and looks like this picture included below.
Many of the patented muzzle devices found in the USPTO are intended recoil reducers, suppressors, flash hiders, etc. that were designed mainly during war times and for military use, but most of them have proven to ALSO improve accuracy and this accuracy part is the origin of our current “Accuracy Tuners and Muzzle Devices”….Maybe down the road some other uses will be found for these artifacts and the name will be changed to ????
For anyone interested in reading more about what is being said, please log into the US Patents office (link below) and plug in any of the the patent numbers on the list below so you can review the claims and drawings of the device being patented.
http://patft.uspto.gov/netahtml/PTO/srchnum.htm
5279200 in 1994 Browning patented the BOSS system which is another variation of a tuner as currently used in .22 RF
4913031 in 1990 Bossard & Pesek from Switzerland patented a muzzle device specifically designed for damping vibrations & Oscillations for improving the “Hit” of a firing weapon.
4726280 in 1988 Guenter Frye patented an adjustable muzzle device for improving accuracy with a locking ring.
4211146 in 1980 Bradley patented a muzzle device consisting of 2 tubes of different diameter attached to the barrel for increasing accuracy.
2953972 In 1960 Sorenzen patented what he called: “A Muzzle Equalizer & Blast Minimizer for improving accuracy and minimizing blast” It is basically an adjustable threaded tuner that moves back and forth with a combination of porting for reducing blast and recoil.
3858481 – 1975 O. Harkness Compensator system for target and sporting rifles
2796005 – 1957 Shapel…A device called “Rifle Control Tube” which increases accuracy
2712193 – 1955 and 1951 Mathis…An adjustable Muzzle device with numbers like a current Harrell tuner
2656637 – 1953 Richards…While designed mainly for shotguns this device has adjustable porting, weight
and has setting numbers also like a Harrell tuner.
1401010 – 1921 Summers…Patented a muzzle device consisting of adjustable tubes/weight and even some kind of liquid cooling for the gases.
The list is endless and all you have to do is to follow the REFERENCE patents listed by the new inventors in order to find more devices and their evolution over the years.
Best wishes for a healthy and happy 2014 to all members.
