Rolling block thumb operated block lever
Oct 4th, 2011 at 11:52pm
 
I've seen a few rolling blocks that have an external lever attached to the breech block pin on the right hand side of the action and is used to raise or lower the breech block after the hammer is pulled back. Is their any connection between the breech block pin and the breech block needed so this works???. Set screw or pin needed. Thanks, Frank

Frank run a search. There have been several threads on this over time.Plus one of the Mags had a big article on the RB conversion. With side lever. If you can't find it let me know and "maybe" Smiley I can find the article. Whitey

You can do it one of a couple of ways.  A screw between the block and the lever axle, or a key in grooves in both.

And if you are really talented you can convert it to roll back the hammer as it rolls back the breech block, this was going to be the last model of the rolling block made by Remington, but not with a side lever. They show a nice example in the Roy Marcot book on rollers. Fruend and Gove also made a conversion that rolled the breech block and hammer back at the same time.

At the same time ?
How can that happen? The hammer must roll back first to make clearance for the breech block to roll back, no?

I dont have Marcots book. How does it work?

You have to buy that book, darned good reference material. Anyway, with out looking at it taken apart it is hard to say, the thumb piece on the breech block is mounted on a separate plate of steel that is in turn pivoting on the breech block. When you first put pressure on the thumb piece it rotates the hammer back by engaging a cam on the side of the hammer, and then when the hammer is back far enough  the thumb piece hits a pin or stop on the breech block and then rotates it down. Nice huh. That is the Remington version. Remington did produce this one but very limited and not many have survived.
The Fruend conversion did it underneath, they took the hammer and added a spur that connected into a pocket that was cast into the lever, when the lever was rotated down the hammer was rolled back and when it was far enough back to let the breech block move it disengages the spur on the bottom of the hammer and just rolls the breech block back. Not really complicated at all. Fruend made a few of these and had a patent to cover its design. Fruend did have a few different patents on roller mods.

I saw one many many years ago. cant remember if it was in a book or where. Do remember it being a novelty.  When I studied the design it seemed to me it would place a lot of pressure on the lever which pushes the hammer back. cant remember if it was a side lever or under lever design.  

Must not have been worth the effort.  Neat though, would love to have one.  

Heres a picture of a under lever roller.  Very interesting rifle. sort of a Hines 57.  Hammer has to be cocked by hand first.

Joe, that looks very Heinz indeed,  but also quite attractive, at least to my taste, though the colors could be a bit more muted. For some reason it looks like owl eyes staring at me. Cheesy    Do you have any more data  on it.

I am developing an interest in the midsized #2 rollers and am thinking a side or under lever on the smaller frame in a smaller caliber might be interesting.

Which one of the Marcot books has the data on the side/under lever versions.  I have the sporting rifle book but don't recall seeing anything on alternate lever versions

The Jan/Feb 2010 ASSRA journal has an article by Ken Erickson showing his side lever conversion

Westeners schutzen roller may be based on an action by Nagant (belgium). They used to make rifles that looked like under-lever rolling blocks, but were somewhat more complex internally. I once tried to buy one in an auction but it went for a lot more than I expected.

That Germanic /Americano  underlever 38/55 rolling block schuetzen rifle was at the Hamilton Montana 100 shot match last year.  

Think the owner told me he had it made per his specs.  The rifle shows nice work.   Dont know who did the work.  Dont know exactly what it was before.

Had my camera on the wrong setting all that weekend, hence the blue'r than regular blue colors.   

I hadnt noticed the owl face. It does look like an owl with the carving.  Grin

Didn't DeHaas illustrate a manually cocked underlever conversion of a roller in his Gunsmithing Idea Book?  I'll have to find my copy and check.

The info is in Marcotts Sporting Remington Roller book. It was the last design and to me looks like a Whitney patent. The same book also shows under lever and side levers by frontier gunsmiths such as my favorite Fruend, and Gove.  Both used designs that you had to cock the hammer back first, and then later they came up with a design that cocked the hammer and rolled the breech block back. Very inventive folks. And to think they did all that work with no power tools at all. Just had or foot operated.
I also have the Fruend book and it is a great reference book for their work. I have always wanted to build one up but never have the time or money.
