Hello again,
JD: I wasn't questioning anyone's knowledge in saying that I was still confused. Yes, I am new to the site as a participant in the forum, but I've been using the site for years. The photos helped me, but still didn't answer my basic question. I didn't see it as an insult to say I was still confused. You seem to suggest this in your comment. I've handled many fine longrifles and caprifles. I've had a fantastic Peter Berry apart on my bench for photos and measurements. In fact, I have an S.Hawken/ St.Louis rifle in my posession right now, a sporting rifle with walnut stock, in superb condition ( no capbox ). I have all the Hawken associated books, including Jim Gordon's boxed set. Now, I have the article that you posted to help me out. Thanks. The scholarship in the article is commendable. Good photos too. All help is appreciated. I didn't need the mini lecture.
Don's response helped me the most because he appears to know how the Track box is constructed. It has what might call a lever or a leg that is cast into the lid. It's on the inside and at a right angle to the lid surface. The lever is under the hinge. So, my guess is that it functions as a cam. Incidentally, the boxes in the photos posted are not the cast box, or at least not like mine, which has only one screw centered on the top surround, like the rifle on page 389 of Gordon's book. Since it must function as a cam, then it must keep the lid shut, and perhaps keep it steady when open.
Don: I'm assuming the box you described had this lever. The hill on the spring would push the lever toward the hinged edge of the box, keeping the lid closed? When lifted open, the lever would climb the hill a bit and when on the other incline the lid would be held open? Is this basically what you recall? I'm feeling like I'm on the right track, but could use more affirmation. This would make devising a catch unnecessary. Please let me know if I'm on the right track ( no pun!).
Once again, thanks much to ALL of you for your help. It's really incredible that folks would extend themselves to help one another.
Sincerely,
Norm Vandal
