two-Shot Capewells Can't Post

As a parachuting teen in the new 60s I was keen on having my gear function. Like everyone, I had two-shot capewell canopy releases. Just pull down the cover, squeeze dinky two buttons together, and your canopy would release sometimes. 2-shots purpose was to allow downed air crew the option of cutting away a canopy after an emergency over windy terrain. The GSA having determined that getting dragged across Tera firma to death after surviving a bail-out was counter productive and messy, added 2-shots as a back up canopy release to the hook knife and chaff in riser pockets.
- Me, being serious about function, pounds 2-ten-penny nails in a tree limb as a coat-hook for my risers. Saddled in. I mime a mal + cut-a-way which would drop me on my ass. No release. No drop. So, an engineering sort, I polish and file the release tabs. More failures albeit smoother. Whilst one side cut away the other didn't. Counting out-loud (i'm a student) ONE-THOUSAND: TWO THOUSAND: etc. etc. I'd get to big numbers before I'd get release. On one side, if any. That concern resolved, I determined that circular 28' C9 flat canopies did not warrant a cut-away noway and proceeded down the yellow brick road to Emerald City.

Years thereafter the introduction of the PC was joined at the hip by nasty spinning Hi-G malfunctions. Then there, in those days of "Reserve Pilot-Chute Removed for Sport Parachuting" shot-and-one-half capewells functioned better than the no-cutaway boogie dance of, "PULL! PUNCH! THROW IN DIRECTION OF SPIN! SHAKE LINES: ASSIST OPENING. . . " ... hope for trees.

Having about 15 cut aways on shot+1/2 and 25 -30 more on 3-rings has reinforced my confidence that sport reserve parachutes work well. Howsomeever, methinks that the USAF still uses shot+1/2s.... this is cool cauz they got no reserve. .... do they still jump rounds? Hope not.

The main reson for the capewell alos was to make the rigs inter-changable . The lines were sewn to the risers the main lift web became the risers etc . If you had a bad canopy but good harness pitch it all . If the rig was bad and a good canopy again pitch it all. Capewell was the name of the company that made the adapters. some Navy rigs only had them on one side to collapse the canopy if being drug in sea water. The 26 foot Navy reserve had sea pockets to help slow down the dragging process.

Oh yeah, all the services still use the old reliable C9 28' canopy as the emergency bailout rig. Harness and containers vary from the B12 but are basically the same rig as back in the '60's.

Capewells were originally designed to release canopies that were dragging aircrew to their deaths.

Then those silly skydivers started using Capewells for a role - in air cutaway - that they were never originally designed for.

The tension on Capewells must be at least double when you are hanging from a partially inflated main.

Gee Whiz Pat, you've done a lot of cut-aways!

We used to practice a far amount on a suspended harness with shot and a half's. I never had any trouble with them releasing.

We used two shots when static line jumping in the army. The ones they had forty years ago looked a little different than the ones in the pictures.

I knew some jumpers, in the early 70's, who had one shot capewells. I was wondering what you thought of them?

 The one shot capewell was mostly on the early crossbow pig rigs . while nice in concept they never really oneshotted. You could pull the covers down then smackthem both at the same time to be gone. That rig had the first RSL in 1964 but you had the make sure you released the right side slightly before the left as ther were no cross cpnnectors between risers. Obviously they worked for me many times with the ropes and rings Paraplane clouds

It may br the only rig now used in the P-3, but other rigs were, and still are, qualified to be used in the P-3.

You have to remember that the the P-3 was brought out in the '60's and the rig shown was not available until the mid to late late "90's.

lost in translation :)

All I meant to convey is that there are alternatives to C9s out there that some of the armed forces use. Otherwise, of course, you are 100% correct, and I wasn't arguing.

Perhaps I mis-spoke....I did not mean to imply that the C9 was used EXCLUSIVELY...only that it is still in use. By the way, what canopy is in that square-look-alike? I find it hard to believe it is a square.

It is called the Thin Pack or Dura Pack. It comes in 3 versions, the basic aircrew like the picture, a version for the P-3 and a third for the E2-C.
They also tried a civilian version.

It was originally developed by a company out of the Phoenix area called Simula. I am very familiar with it..I was involved in the testing both for the Navy and for the TSO. I did all the live jumps on it for the TSO.

Quite a display of various ways to release canopies. All employ the concept of leverage or other mechanical advantage to decrease the tension on the actual release point beginning with modifications of the capewll system, then to webbing arangements. This can be viewed as the evolutionary path to the 3-ring releases that are seen on virtually all modern sport rigs.

Fascinating and educational.

Except many of them evolved after the 3-ring system was already on the market.

Re: [mjosparky] two-Shot Capewells [In reply to] Can't Post

It was originally developed out of a company in Asheville NC, SEI or Safety Equipment International. I worked there directly with the Navy test jumpers and Engineers out of China Lake, CA to develop the packing and sealing processes of the P3 and E2C parachutes.

The Navy has since taken control of all the drawings, which is why SEI, bought and moved to Phoenix, renamed Simula, then bought by Armor Holdings, then finally sold to BAE Systems no longer manufacture them. They called it the Durachute and did not have much demand for their civilian version.

And yes, it had a Five year repack cycle due to the vacuum sealing process.

It was developed by Simula a company in Apache Junction just outside of Phoenix. SEI is a division of Simula. AERO a company owned by Joe Crotwell was involved in the testing of the base unit testing and also the P-3 and E2-C versions. If you were working with the guys at China Lake you will remember the King Air used in testing. That was AERO,s plane. At time I was director of air drops with AERO.

The guy in the gray jumpsuit is the Simula rigger who was responsible for most of the design work.

Re: [mjosparky] two-Shot Capewells [In reply to] Can't Post

Okay...a little of my background with SEI. I worked at SEI in Asheville,NC from 2000-2003. I worked with 3 designers and several individuals who jumped and did R&D with the P3 prior to my arrival there. At the time, SEI was not owned by anyone else. It was purchased by Simula while I was there. Simula opted to close the Asheville site in 2003 and moved it to Apache Junction, AZ. I still keep in touch with several of the navy test jumpers that jumped, Gabbard, Mark Esposito and Howie Tomlinson. Tomlinson still works at China Lake with the 2 vacuum sealed systems the Navy developed with the company I worked for. I never made a trip to do the test drops, that was prior to me arriving. I assembled, packed, vacuumed sealed, and closed the systems before shipping to the navy. I just wanted to add a little bit more of the history of the Durachute, not to stir up any animosity.

I jumped (and used) One-Shots after I got off student status. Mine certainly didn't work that way... Just pull the cover all the way down and you were gone. I did 2 intentional (practice) cutaways and one from an actual mal with them and they always worked perfectly (and way faster than 1.5 shots).
There were some who said you should pull them down to the cocked (half open) position and then slap them to the harness, but it just was not necessary.

the cutaway I remember with my one shots was when I had to cut away from my hot 5tu and due to the 'slippery' gloves I was wearing I only released one side as my hand slipped off the other cover. So I transitioned to a more exciting instant streamer.

Hi Roger,

If you used OneShots then you were a rarity as they only came on the CrossBow rig.

Security would sell the OneShot capewells ( I bought a set from them ) but few knew this. And of course Capewell developed the 1 1/2 shots soon after and that became the most installed/used device.

You post is correct. However, when Security brought out the CrossBow with OneShots they said to activate them as lekstrom says; a 2-step process; although there was no mention of activating one side before the other.

I bought mine from Mid Ohio Parachute where I bought all my supplies for rig building. There were only a couple of us at Z-Hills using them. Some thought they were dangerous and would release with just a knock, but they would stop half way open and you had to pull them near 180 degrees to actually release. I was jumping a lot of the early squares and liked the idea of a quick cutaway in case of a bag lock or other high speed mal. In 7 years, 1000 jumps and 3 cutaways (2 intentional), I never had a problem with them and would not hesitate to jump with them again though there is no reason these days with the 3-Ring.

Re: [RogerRamjet] two-Shot Capewells [In reply to] Can't Post

A couple guys in our club had one shots. It was my understanding that if you jerked the covers down, it would cut you away. The thought of that scared me. Yep, I'm a "Wuss". I was happy and safe with my shot and a halfs.

I used to put my arms out, and try to sit up, to soften opening shock. My para-commander often had slammer openings. One day I had a really fast, hard opening. My arm tore the cover open on my shot and a half, on the right side. I kept thinking....man I'm glad I didn't have one shots! That would have cut one side away.

I looked up to people who jumped pig rigs with one shots. They were brave soles in my book.Wink

No you don't have to list every rig. The reason for the original reply is because you said this:

Quote:

I just wanted to let people know that it wasn't only the Crossbow rig that had them. If that wasn't in there I wouldn't have responded and cite another example of a rig that had them. I will have to work on the clarity of my responses as they are apparently being taken in a way not intended.

My first cutaway was on two shot capewells(1973). Lots of exposed metal for the reserve to go by. I quickly switched them over to shot and 1/2's.

Plenty of exposed metal on those too, saw my 1st fatality about '76 with a belly-wart pilot-chute hung up in an activated shot & a half's...I went to R3's the next day.

And to think that most of us, felt relatively safe, jumping that junk! "Ignorance is Bliss".

I was taught. Throw ripcord away. Assume the cut away position. Cut away. Left arm across the capewells, look, pull reserve with your right hand.

I think most of us were taught that way, but if a student had a Stevens lanyard...good luck! Wink

Hi Mr T

I think the only jumping that will be around in 25yr's might be Tandems If the industry continues to head in the direction it's going.Frown

Fun jumping might continue in a tunnel or there will be a app for that. Unsure

Times change, shit happens, the latest and greatest etc.

The latest and greated will save fuel and time,reduces the NOISE level, for the NIMBYS, reduces the carbon foot print, slow down global warming wll help save the planet, less injuries, no more airport issues, listening to McNasty whineing etc.

The new age "jumpers" won't know any better.Unsure

Anyone else want to take a guess about the future of the industry and the sport in 25 yr's. We'll hook up in 25 yr's and laugh about who got the closest and how far off we were.

R.

In 30-40 years I see jumping gone full circle. Dawn somewhere on the great plains, a couple guys climb in a 170. Climb to altitude, push the door open and jump out. No cameras, no notam, no DZ, no go light, no nothin, but a skydive.

Re: [patworks] two-Shot Capewells [In reply to] Can't Post

I don't know who exactly I am replying to, but: This tread has gone far afield from the question about how a Capewell/One Shot works.

To the original guy who queried how 'One Shot'Capewells work: Please follow along with the progression. . The tang which ultimately holds the first two Capewells closed, is located at the bottom of the trapezoid fitting which is sewn to the risers. This tang is a hardened steel projection, which is held in place by the sliding portion of the female (attatched to the harness) fitting. For the two shot and the shot and a half, It does the real work of taking the strain of opening shock and the weight of the parachutist.

Covers: The covers (there are three) prevent an accidental release, and of course also help to hold the riser fitting in place. The first Capewell in common use was the "two shot" which requires the pulling down of the cover, and then the user presses the side buttons together. Not very reliable, as the pressure is sometimes great, and as Pat Works related-one side sometimes releases and the other one doesn't.

Shot and a half: See the pictures of Mr PC Chapman. The cover is pulled down/open and the cable loop with the two swaged balls pops out rather nicely. You put your thumbs in and pull down hard, and the cable pulls the two projections together, and when those projections release, the sliding block moves downward, which releases the tang. When the tang is released, the riser flies way, the same as the two shot.

One shot cover. It is also spring loaded and pops open when you pull it down. Same idea as the first two above.
The difference between the "One Shot" and the first two is this: There is a short internal cable which is attached to the hinged cover on one end, and to the sliding block on the female fitting. The sliding block slides down Just like the previous ones. If my memory serves me correctly, the 'one shot' trapezoid fitting attached to the riser lacks a tang. This is unimportant, as the sliding block still locks the 'long arm' of the riser fitting behind it. Once the sliding block moves downward, the trapezoid riser fitting is released-tang or not. The release of the bottom portion of the 'long arm' of the riser fitting is what allows the riser to fly away/release. So. The design difference of the 'One Shot' is that there are no upper projections to be pulled together. The spring loaded cover alone is the security. The operational advantage of the "One Shot" is that the downward motion of the block (which holds the bottom portion of the trapezoid riser fitting) is accomplished by the short piece of cable connecting the outer cover to the sliding block. (Additionally, the cover is hinged). If you pull it down far enough, it releases the riser with one motion and there is no necessity to regrip anything. Hence the name "One Shot"

It does require a full pulldown/stroke to accomplish the release. Very shortly after this third permutation of the Capewell release was invented, the three ring of Bill Booth came into play and so there weren't that many "one shots" used on sport rigs.

There are several-many USAF film, professional, full color, on deployment and use of the Capewell Mfg. '2-shot' canopy riser release. The storyboard and narration highlight that the release was so that a downed air crew could release one-side of the canopy prior to being drug to death. Texas A&M ROTC we ate 'em up.... lots of nice ejections, hard landings, and landing winds that gave pucker. Somewhere these films still exist. ?

Re: [patworks] two-Shot Capewells [In reply to] Can't Post

In reply to:
As a parachuting teen in the new 60s I was keen on having my gear function. Like everyone, I had two-shot capewell canopy releases.

Me too. I went through jump school in 1960 with the 82nd Airborne at Ft Bragg. I started sport jumping with the XVIII Airborne Corps club. The only release we had on both military and sport rigs were 2-shot Capewells.

I witnessed my first fatality when jumping with the Corps club on Sicily DZ. My free fall instructor went in because of the great difficulty with 2 shot Capewell when packing in the gritty sand of the DZ.

He was a bit heavy, the wind a bit strong and guys would often do the first step of cutting away before landing so disconnection of one side would be easier and we wouldn't get dragged.

About 250 feet from the ground he did the first step but something went wrong...probably a poor closure of the Capewell...and the riser came completely disconnect with the first step. He never had time for his reserve to inflate.

I vaguely remember that we filed off a tab on a part of the assembly which caused what I describe to happen. Too long ago to remember exactly what we did to the assembly, maybe someone else can remember the exact modification.

Don landed about 100 feet from me. It was scary and horrible. Needless to write, those who made that modification went back to original equipment after that.

Note: I just re-read this. Actually, sport rigs didn't exist back then. We jumped military canopies with gores removed. During the time period the Army team jumped seven gore TU modifications which were considered "too hot" and dangerous for "beginners" like myself,
