    Joint Check pictures and operation Archived Message

    John had written in asking about this mechanism and I had a circa 1897 Grade 3 apart and decided to take the joint check from the barrels. Now I can see why they discontinued it. What a marvel of mechanics. I know that only the very best machinists worked on these.
    I've enclosed a few pictures to show how it works: The action is opened, the pins are in the slots of the receiver, as the barrels go downward the inside cam is rotating and when the curved piece comes in contact with the extractor stem it pushes it out. Upon closes the breech it reverses itself and the extractor is either pushed by hand or closed by the barrel closing fully.

    Also I posted back to John about the serial number being on the joint check, it is the serial number to the gun.

    I also put a few pictures of how the safety worked on these pre-1913 guns, very interesting and yet very simple. From the patent of Oct.5, 1886 this shows how the safety was used. I would love to be able to see a pre Oct.1886 and see what type of safety they used.


    Count the different steps just to make this piece.




    Trigger assembly with safety pin circa 1897

    The safety post is missing from this gun. I think I will put one in it, because I would feel safer
