How a Retractable Ballpoint Pen Works
Вставка

- A ballpoint pen seems simple: press a button you can write, press again and put it in your pocket. Yet inside a clever mechanisms turns that simple push into all sorts of other motions. This video uses detailed animation to look inside the iconic Parker Jotter ink pen and see how it works. You can become an advanced viewer of engineerguy videos by signing up at www.engineerguy....
I could listen to this guy narrate my own murder and I'd still be interested.
Hahaha I totally agree!
If I was earing someone tell me how I was going to be murdered, I'd also pay close attention.
You should check out his audiobook
"Now, the murderer will attempt to dismber the corspe. You can see that he has expertly hidden it under the floor boards. Later, when the police investigate, he will crack."

I clicked this video so quickly when I saw it in my subscribe feed!
+Luke Beacon I clicked it four times...
+MrGeekGamer I only pressed the mouse button twice, but it emitted four distinct clicking sounds.
+StraightOuttaJarhois I thought you were joking for a second, but that's actually true. Never thought about it.
StraightOuttaJarhois next video: how a mouse button works!
It is incredible how quickly this has become my favorite channel.
Gosh I've been taking apart pens and putting them back together for ages and really happy to have the physical process of how the cam turns explained to me. The other day I took one apart that used another spring to complete a circuit when pressed making the pen glow.
This video is meant for the %10 who don’t disassemble their own in class
more like 1%
But it is incredible that Parker Company wasn't confident in ball points, despite the patented device, and didn't put their logo on the first ones. I wonder if those are worth something now...
This is such a simple product - but to just think of the hours people spent on designing and prototyping back in the 60's it's an amazing feat of Engg. As always a great pleasure listening to you describe every single last detail of this pen. Kudos :)
Taking a pen apart and putting it back together is the first right of passage that an engineering takes
I have been wondering the details of this for 20 years, I never put 2 and 2 together with the spring and the angle. Thank you for sovling a small mystery in my life.
Great video! I remember just clicking my cheap retractable pen over and over again and watching the mechanisms at the top slowly rotate. Nice to see the mechanics explained so clearly.
Its such simple items that we use pretty much everyday that have some of the most incredible engineering! Thank you so much bill for these truly wonderful videos. I look forward to the next video!!!
I have a pristine black parker jotter. I will never write with it. The most satisfying click ever. Its a treasure.
I used to get bored in class and would take them apart and put them back together. Probably done it hundreds of times. Pretty ingenious.
I have actually sat with a magnifying glass to figure this out, but it happened so quick I never really figured it out. I could tell the cam body went around and around, but couldn't work out the locking mechanism step by step action.
+lazygamerz i did the same during a slow class and i semi-figured it out. Altough i could never describe it as elouqently as Bill does.
It seems like a surprisingly complex (although elegant) mechanism for quite a simple action.
Have you guys considered starting a Patreon campaign, like Crash Course, or Smarter Every Day?
I'm having LEAN workshop flashbacks from this. We have to improve process flow in a retractable ballpoint pen factory. It used a similar but slightly different mechanism. I must have put together and taken apart 100 pens that day. I never thought about what exactly caused the clicks. That was a very nice visual you put together there.
bill... i have been talking about the 3rd style click pen for years. I never saved one and now I can't find it anywhere. That design warrants an animation. It is one of my favorite designs. using the ink tube as a buckling spring is ingenious!
I always love your videos, the visuals used were great!
I have one of the newer Parker jotter pens, and I absolutely love it. This video made me love it even more by learning the engineering that went into this beautiful pen.
I’ve been using Parker Jotters for years, so was thrilled to see this video. Well done!
Great video! Thanks!
You can apply the pen mechanism to any product/tech and your engineering prof. will give your high marks.
I could never completely wrap my head around this concept. Amazingly well done video. Thanks!
I've taken a pen apart before, but this video and the animations explain some neat details I've never thought about. Love it.
This guy is a genius. If only because he can explain things so simply.
Tanks! A video about the mechanism of the click-less, silent Caran d'Ache Ballpoint Pens would be very interesting too.
Wow, this was great, and I was worried I'd get lost after seeing that patent page. Engineering is amazing.
This is so complicated for ten for a dollar pens. What a glorious feat of engineering!
Great video and animation as always. I looked up how click pens worked before but nowhere can I fine a more straightforward and clear explanation.
Nice animations, it would be very difficult to explain without them.
as a mechanical design engineer, some very common daily engineering applications (like the ball pen) accumulate some many efforts of engineers generations by generations. The mechanism of ball pen is still very insightful for mechanical design.
That moment when you ask ur friend to borrow a pen and you give it back in pieces ur friend be like: *;-;*
These renderings are beautiful to work through each of the motions, thank you for this.
an everyday object that we take it for granted and take it as a simple thing hides an ingenious mechanism inside of it!
Thank you for this clear, well-illustrated demo! Now, could you please create a video about the compact, alternate-action electrical switch in the tail cap of a flashlight?
Where can we suggest subjects?
I think the ToastMaster is the cleverest invention of the 1930s. It self lowers, self raises and uses infrared to know when the toast is done.
I would love an exposition on those water bottles that let liquid out when you suck, but not when you squeeze.
+Walter Clark Wait, they had that stuff in the 30s but now in the 2000s im burning my toast? Is evolution going backwards?
+sc0tte1
I know. That's why the thing is so incredible. No motors. Just rods of special metal that expands with heat. And a thermostat that looks at the toast.
I found his email and suggested it, but like all famous youTubers, he never looks at suggestions.
+Walter Clark WHaa? Since when did toasters have some sort of system that "looked" at the toast to see if it was done? I thought it was all just done via timers, as that seems to be the simplest way of doing it as all bread is mostly similar. Or are you referring to a specific toaster? I've never heard of the "toastmaster".. if so, why do modern toasters burn toast?
+kekejojo1212 Glad you asked. Yes today they are timed, but the original Toastmaster patent had four mirrors that allowed a thermostat to ONLY see the surface of the toast; not the heating elements. When the toast radiated some amount of heat, it triggered the thermostat and the heater was turned off. That meant the mechanism that kept the toast down cooled down and the toast slowly rose. It took about 7 seconds to rise up instead of popping up which is probably what most people want.
I remember as a kid taking apart my pen and trying to figure out how it worked; oddly fascinating video!
Super presentation...in a "very" engineering style! LIKE!
That's such a clever mechanism
Great video! I've actually taken it upon myself to understand how a click pen functions a few years back by disassembling and some thinking. Truly magnificent design if you ponder about it long enough!
You're the only to make pens an interesting video. Amazing!
finally i can go back to my project thx this video was hard to find
Another awesome video! Great work, keep it up! Start naming the physics principals at work in each product and you'll have a winner every time.
This vid helped me repair my Parker Jotter pen. Thank you!
A little piece of art and ingenuity...
What a great video - love it! I'm not an engineer or anything like that - but I just love knowing how things work.
Bill, you really can sell a pen! good explanation, thanks.
At the end they were so humble ♥️👍
As always, excellent video
Excellent video! I wonder if mechanical pencils works with similar mechanisms..
So satisfying to watch!
this is such a high quality video
Excellent video! Really clear explanation. Thank you!
This is amazing. Such beauty in an everyday pen.
Fantastic explanation into how something works as always!
What a delightful video! I would love to see more of the same, examining other everyday objects.
I’m intrigued by the triangle thingy pen at the beginning
boy you sure know your pens...that was awesome thank you!
Thanks so much for making this lovely video! Very informative and I have never even thought about how pens work!
please keep it up bill
In love with this channel !
Brilliant channel. Super smooth and informative
Pure genius!
YOUR BACK!!!!!!
Now I want to see how the third type of mechanism you described works.
When your teacher tells you to stop clicking your pen out you need to click it again to retract it
+engineerguy - Fantastic explanation. Thanks for sharing.
those are good pens!
Wonderful explanation. One comment: miss the background music you used to have.
Engineering is like useful art.
Great video. I love retractable pens! Maybe now I'll know how to fix a pen (or refer to this video) if it ever happens lol.
This channel deserves more subs! Keep rocking, you're awesome.
Same design used in the push button electric switch
You're amazing. Thank you for all your works.
Pretty neat. I'm still a die hard fountain pen guy, though.
I did the exact same thing in a boring English class in middle school. It felt nice to figure how it works XD
Вместо стержня поставить шток с мебельным колесом и получится отличный миханизм для установки под диваны или камоды, для легкой дальнейшей транспортировке по квартире, приподнял угол с колесом, шток выдвинулся и зафиксировался, потом еще раз поднял, колесо спряталось, и шкаф стал на свои ноги.
Wounderful
That was great.
I have always owned a Parker pen. Black ink. I like the balance and the clean look. And the price point is nice. I think the arrow is a nice touch in the design of the pocket clip. I've tried many different brands of pen but I have always found the Parker to be the most reliable. I usually lose the pen and buy a new one... ;-)
I use both Parker and Papermate pens and find them equally reliable. I've had my present Papermate for 20 + years.
How do the Ballograf pen mechanism and the Fisher space pen mechanism work?
great video
Brilliant.
thanks always love these
Watched 15 times, it's a beautiful!
Ingenious!
What about that, thin graphite that you put in pen instead of pencils, how do they work?
Love your videos.
I really love this channel!
I was curious about why the top that you push was loose in the writing position, but sprung back in the retracted position. One day at school when I had nothing to do for 15 minutes, I stared at a clear-bodied Pilot G-2 pen and clicked it over, and over, and over until I figured out how it worked.
I never knew I needed to know this, but I hella did
In a recent business trip to the east coast of Africa (Tanzania & Nigeria) I found out that a "click" pen is held to high esteem. As my partner & our potential business partner were finalizing our deal, I pulled out my "click" pen and the room went silent. Our hosts explained to us that because the "click" pens were more expensive, as such, local merchants using these were seen as more successful. All because of a "click".
Congratulations!
This is intense.
My grandfather gifted me a pen which I thought was just a normal parker, I saw this video and I realized it is the same pen that he has and says in one of the first click pens. Mind blown
i feel complete after watchin ur vids ! Great work ! Team #Engineerguy
Your videos are always the highlight of my subscribe feed ;-) Can I ask, what are you using for the animations? They are flawless!
keeping those algorithms happy...
Twenty-five years ago, I had passed the thesis exam for rotary head pistons, explaining the working principle of this in 2 mins.
Is that the Jade colored parker jotter?
