A friend's house my father took us to as children in the mid 80's had an ancient Sheffield handcar that was massive for me at that age. I was maybe 8 or 9 but had deadlifted 100lbs and was determined to get the thing moving. I also remember the first time I got it going and my sister nearly crapped herself, then I got it hauling ass! lol *The irony is, that family friend was an engineer but an actual Mechanical and Electronics/electrical engineer and I came to this video because I am an inventor, all around mechanical and electronics/electrical engineer.* I am researching the mechanism in relationship to an invention of mine.
I am more interested in the biomechanics of the work. If you are pushing down on the handle - does this decompress the spine? If so it is like a reverse of the deadlift.
This mechanism allows you to change the direction of motion (reverse), that is to go back? Or it can only move in one direction? Sorry, English is not my native language.
Look up the US-Patent US265987 online. There is nothing preventing the handcar going backwards. It just depends on which of the levers you push down first. (or in which direction gravity is pulling you)
Hi meka. I've just seen a video on a gear linkage that I think you'd be interested in. "three gears are possible - numberphile". The last example converts linear motion in one direction to linear motion at right angles in what may be the best possible way.
Um that's what you have a problem with. How About NO, eyes, ears, nose? Or the huge round discs for knees? Or the fact that they have NO hands to hold on to the levers? LOL yeah I think their over starched pants is the least thing to worry about.
The gear wheel is engaging/turning the axle directly, so it makes the axle turn in the opposite direction. There is no chain like you would see in a bicycle. If a bicycle didn't have a chain and the pedal wheel drove the front wheel by contacting it directly, you would have to pedal backwards to go forward.
@@Blazerfan11 Ah yes, I figured out after a bit that there the cog that is being turned is the one that is turning the axle, thank you! This whole thing actually reminds me of a rowing machine where you have the push phase and the catch phase :D
I came to this video to see how railroad handcars operate and to understand how actor Dick York (of BEWITCHED fame) had injured his back during the filming of the movie THEY CAME TO CORDURA.
Quando eu era criança eu via muito desses trolei manual na ferrovia perto da minha casa, e tinha também uns trolei motorizado que corriam com uma boa velocidade. Mas isso acabou!
I also own a hand car such as this one. With two people each would face the center of the car and pump using a hand on each side of the handle inserted into the walking beam. The direction of travel is obtained by kicking the wheel with the foot in the direction wanted.
hey i am back for a re come back to study about the handcar but i instead will make a model of a newcomen engine but powering a sheffield hand car so i am going to study more about this
The person who made a video about how a hand cart works has never seen a hand cart up close.... And even asked if people who have used a hand cart knows if this is accurate or not.... wtf!?!?!?
Do an animation like that just using math (no frame by frame animation) than say ouch. Do you think that I did not see that? I am waiting your animation to see how elbows move.
@@mekanizmalar Someone made this comment and it made me laugh(not at you , them). "0:20 Red shirt guy's trousers still stay standing when he bends" My response was.

The black haired men is standing wrong in my opinion. Take a look at US-Patent US265987 (on which this is clearly based on). it would be uncomfortable to stand like this. I did my own animation based on the patent drawing: commons.wikimedia.org/wiki/File:Hand_Car_Animation_with_men_-_small.gif From my point of view, it makes much more sense, when the two men are facing each other. Sure, only one can look a head, but: The hand car is on rails, man powered and has breaks.
Both men shown in my animation are in correct position. In actual Sheffield handcars there are 4 person powering the handcar. The way you show the men is not correct. There is one instance where one of front driver wanted to protect himself from cold wind and he powered the handcar backward. He died in an accident because he was not looking forward. Here is a link you can look at where people using correct powering position for the handcar I show in this animation. www.villagelife.com/news/handcar-derby-kicks-of-21-year/
Thank you for the reference. I was guided by the walking beam D in the patent drawing figure 3 where the handle bar E is connected in away/distance, so that the wallking beam would get in the way: commons.wikimedia.org/wiki/File:US265987-_Patent_drawings_colored_in.png (I colored the drawing because I think it is easier to read the drawing when the same part allways has the same colour) Interestingly, the patent is not describing how the hand-car is operated, instead it refers to "the usual way". I have found older patents showing a configuration that would easly allow the operators to stand as in your animation. Hmm... I presume that both ways of operating existed, but safety concern have since clearly pushed toward the operation shown in your animation. The position of the break also makes more sense how the people are standing in your animation. (yet: Seeing that the walking beam has no free run, speak it move up and down so long the car is driving, I can presume that safety really wasn't a primary concern in 1882)
why is it called a sheffield handcar? was it invented in sheffield? by someone called sheffield? consider recording your own audio, text to speech is not great. :)
Thanks for explanations of yesterday inventions, which may come back in an updated modern form.

I may be wrong but I do believe the simple mechanics is basicaly the same as a Treadle Sewing Machine.
also i thank you for teaching the mechanism so i noticed the large wheel with the piston part was simular to the steam engine so i took inspiration

@@sarowie Thanks for the answer, I was curious about this myself.
I want to miniaturize and adapt the pump mechanism into tiny go-karts.
Thank you for your comment and good luck in your endeavor.
We had a ride on toy made just like this,been searching for it,can't find one like it

Thanks Ray. When I see smart people like that it makes me more humble. It was a good video, I liked it.

Both of them mechanically formed.

I've seen one in person, but didn't get to ride on it.
Nice animation.
Thank you.
I own a Sheffield Hand car circa 1890 if you have questions please ask
Tom Wagnon how much is it worth
Quando eu era criança eu via muito desses trolei manual na ferrovia perto da minha casa, e tinha também uns trolei motorizado que corriam com uma boa velocidade. Mas isso acabou!
Yes, we replace everything manual to a power driver devices. Down size of it we all lost healthy life style.
I also own a hand car such as this one. With two people each would face the center of the car and pump using a hand on each side of the handle inserted into the walking beam. The direction of travel is obtained by kicking the wheel with the foot in the direction wanted.
Dear Roy, Thank you for your informative comment and support.
you don't own this
what software u used for that
Adobe Flash.
great video sir.....
Thank you.
It's complete BS!!!!!
Tricky to overtake when you race, should be Olympic.
I keep thinking it’s the announcer from BFDI
hey i am back for a re come back to study about the handcar but i instead will make a model of a newcomen engine but powering a sheffield hand car so i am going to study more about this
Thanks for the video very helpful
Thank you for visiting my channel and for your encouraging comment.
I hope you know it was completely fabricated
You are wrong they are a joy to ride.
The person who made a video about how a hand cart works has never seen a hand cart up close.... And even asked if people who have used a hand cart knows if this is accurate or not.... wtf!?!?!?
I had a toy made like this,me an my brother wore it out,never seen another one like it though
also i feel free to learn more
those elbows...ouch

On the other hand, you are right, it must be a magic to twist elbows like that.

robot voice is horrible
türk wtf
What a waste of time.
