In 1857, when Smith and Wesson first started making revolvers, the guns they made were known as Tip Ups. At least that's the name we know them by today. Unlike the Top Breaks, which came later, and opened by rotating the barrel down, a Tip Up was loaded by releasing a catch at the bottom of the barrel, and then rotating the barrel up. Then the cylinder was pulled forward out of the frame. The cylinder was loaded and it was reinstalled on the frame, then the barrel was rotated down to close the latch and the gun was ready to fire.

This is a Number 2, Old Army. This model was produced from 1861 until 1874. This particular one left the factory in 1870. It is chambered for the 32 Rimfire Long cartridge and the cylinder held six shots.

Here is a photo of the gun broken open for loading. The rod under the barrel was used to poke the spent cartridges out of the cylinder for reloading.

A few weeks ago I came across another one. It was in very nice shape, although it has clearly been refinished. But something about it was a little bit unusual. The 'ejector rod' under the barrel had been partially turned down to a smaller diameter.

When I opened it up I saw that it had been modified to shoot 22 Rimfire ammunition. The chambers and the barrel had been sleeved. A little bit of steel had been welded onto the face of the hammer and shaped so it would fire the smaller 22 RF cartridges. The rifled bore was bright and shiny, like new, as were the sleeved chambers.

I have never wanted to shoot any of my other Tip Ups, even though I have a couple of boxes of the correct ammunition. The guns are too old and I did not want to chance it. But clearly this gun, with it's modern steel sleeves and chambers would be a different story, so it went home with me. The gun functions perfectly, and it locks up almost as tight as when it left the factory. No, I don't know yet exactly when it left the factory, but I suspect from the Serial Number it is a very early one. At some point in time, probably fairly recently, an unknown gunsmith did the conversion.

I did not want to shoot modern 22 Long Rifle ammo out of it, even though the barrel and chambers could probably take it, I did not want to subject the latch to the force of modern Long Rifle ammo. But then I lucked into a few boxes of CCI 22 CB Longs. Kind of like the old CB Caps, loaded very, very mild.

So I took it to the range and fired a few cylinders full out of it. What fun. The CB Longs recoil about like a BB gun. With its bright shiny new barrel sleeve the gun is very accurate. I didn't want to overdo it so I only fired a few cylinders full.

Here is a photo of the three different sizes of Tip Ups that S&W made, compared to a modern K frame 38. Top to bottom in the photo are a Model 14, No. 2 Old Army, No. 1 1/2 New Model, and a No. 1 Second Issue. The upper two are both 32 RF, the bottom one is chambered for what we eventually came to call the 22 Short.

S&W controlled the Rollin White patent when they were making the Tip Ups, which prevented any other American manufacturer from making cartridge revolvers. When the patent expired in 1869, other manufactures could start making cartridge revolvers too. The No. 2 was popular with Union officers during the Civil War. Not as powerful as the Cap & Ball revolvers built by Colt and Remington, but it could be reloaded much quicker.

S&W never made a Tip Up larger than 32 caliber, although they experimented with a 44 caliber prototype. They concluded the action and lock up of the Tip Ups was not strong enough for anything larger than 32 Rimfire. In 1869, when the White patent expired, S&W introduced their first Top Break, a much stronger design. The first Top Break they built was the 44 caliber American Model.
 
Very cool Driftwood. Nice acquisition. Thanks for sharing. I've wanted to pick up a tip up for several years, but never find the dollars to get a good example. Never thought I'd hear of a conversion or of someone shooting them nowadays.
 
Very cool; thanks for posting. I've never seen a tip up in person but I've read of them and seen pictures. An interesting bit of firearms history.
 
Everytime you post your revolvers, I leave this forum very jealous. You have some nice revolvers. Thanks for sharing. Im curious how it shot.

Driftwood,

Thanks for sharing those very fine guns and your very fine knowledge.

That sleeved .22 RF version is super keen-o-neato. Does make one wonder if that might not be a fun project for someone with a BP era top break as well....with CB powered rounds of course.

Thanks again.

Very out of the ordinary and very cool S&W revolvers! Really like the one modified for .22LR. Interesting bit of history to go along with those Tip-Up barrel guns.

The mechanism the Tips Ups used to lock the cylinder in place was very unusual, at least in modern terms.

Unlike almost every revolver made since then, the bolt was positioned above the cylinder, not below it.

In this view, the part extending back towards the hammer is the bolt. Yes, it is actually the bolt, trust me on this. SCSW calls it the Cylinder Stop Leaf.

Directly under the bolt in this view is a spring.

Side%20View%2001_zpsoq3drmnx.jpg





On top of the hammer is a rounded cam. Notice the front edge of the cam is wedge shaped.

Hammer%20Detail_zpsfiwutmsw.jpg





Here is a view of the spring under the hammer. Notice the fork shaped recess. The spring is split, it is only joined together near its front.

Split%20Spring%20Detail_zps8hsxrzsg.jpg





And here is the business end of the bolt, protruding down through the top strap. In this view the hammer nose is also visible, protruding forward through the recoil shield.

Bolt%20Detail_zpssmz1t8pd.jpg






The way it worked was, the bolt could pivot up and down slightly on the forward pin. The other two pins held a hidden spring in place which exerted pressure on the bolt to keep it down, locking the cylinder in place. When the hammer was cocked, the rounded portion of the cam would lift the split spring up, which in turn lifted the tail of the bolt up. This freed the business portion of the bolt from the cylinder locking slots, allowing the cylinder to rotate. Once the cam cleared the tail of the bolt and the split spring, the downward pressure of the hidden spring would cause the bolt to pop into the next cylinder locking slot as it rotated into position.

But when the trigger was pulled, the sharp wedge shaped portion of the cam would force the two sides of the split spring apart, allowing the hidden spring to continue to exert downward pressure on the bolt. The downward pressure kept the bolt engaged with the cylinder.

All in all, a very simple, elegant system.

Unfortunately the split spring could break where its two legs joined together. One has to look carefully when a Tip Up is found today to make sure both legs of the split spring are still there.



As for accuracy, the rear sight of the Tip Ups was a tiny V groove cut into the rear of the bolt. I am aiming one right now, and I can't even see the rear sight in the basement. I could barely see it in daylight at the range. I did a little bit of shooting off a rest, so I could steady the gun to see the sights, at a very close target. Accuracy was quite good, I shot a reasonably tight group. But practically speaking, if one was in a pool room or a battlefield, one would pull the pistol and point and shoot, probably without using the sights at all.

FWIW, the S&W First Model Hand Ejector (aka Model 1896) used the same kind of cylinder stop in the top strap, split spring and all. There has been some speculation as to the reason for reverting back to that system on what was otherwise a "modern" revolver, but IMHO, it was simply a matter of time. S&W needed to produce a swing cylinder revolver to compete with Colt and the First Model Hand Ejector* was it; the attitude from the front office was probably to "get something out there with a swing cylinder and we can refine it later." Actually, the system worked well the second time around, but was soon discontinued and not used again.

*The term "Hand Ejector" (or H.E.) was used for decades by S&W to distinguish its swing out cylinder revolvers from its top break designs, even after the last top break had been discontinued in 1940. The earlier guns were designated as "automatic ejector", meaning that fired cases were ejected automatically when the gun was opened, where the newer guns required a separate manual operation of the ejector. But, why replace something "automatic" with something that required an extra motion? That sounds like going backward. But the top break system could not be easily adapted to long cases, and attempts to do so had not been too successful. Since in the days of black powder, more power meant a longer case, S&W chose to go to the swing cylinder, which not only had a stronger frame, but could have a longer extractor stroke than was possible in a top-break.

Love your posts, Driftwood. A great way to learn about some old obscure firearms...from a person who owns them! Have fun!

Jim K makes a good point about the cylinder lockup system of the Tip Ups being resurrected in the first side swing revolver that S&W made. I would only make the comment that it is usually known as the 32 Hand Ejector, 1st Model, (Model of 1896) to differentiate it it from the 38 Hand Ejectors. By the time the first 38 HE was produced in 1899, S&W had gone back to putting the bolt below the cylinder, where it has been ever since.

Can't comment on why the bolt was above the cylinder, but Jim's argument for expediency makes sense to me.

This weathered 32 HE 1st Model shipped in 1898. The 32 HE 1st Model was replaced by the 32 HE 2nd Model in 1903 and the bolt was down below the cylinder again. Other distinctive features of the 32 HE 1st Model are the lack of a thumb piece to open the action. The cylinder is released to swing open by pulling forward on the ejector rod. And the slightly squared off appearance of the frame near the hammer was never repeated again either. The 32 S&W Long cartridge was developed for this revolver.

32HE%201st%20Model%2003_zpse8iiptp6.jpg





In this view the bolt, or cylinder stop, pivots on the pin above the cylinder.

The hammer has a similar cam, except in this case the cam is an integral part of the firing pin.

rearsightandfiringpin_zpsaad5d7b8.jpg





There is a similar split spring under the bolt.

splitspring_zps15effa86.jpg





The rear sight is an integral part of the bolt. The sight is positioned directly over the pivot pin. I suppose it was placed there so there would be minimum movement as the hammer was cocked. If you cock the gun slowly and watch the rear sight, you can see it rock slightly.

rearsight01_zps8edf7451.jpg





Here is the 'business portion' of the bolt protruding down through the top strap.

bolt_zps54afd4c2.jpg




There is a marked similarity to the Tip Ups, in this case a 32 RF No. 1 1/2 New Model.
