Having thus fully described the manner in which I combine and arrange the respective parts of my permutation lever lock, I do hereby declare that I do not claim as of my invention either of the parts of this lock taken individually, but only as combined and co-operating with other parts in the manner set forth; but what I do claim as new and of my invention is, first, the manner of arranging and combining the hoop A with the revolving plate C, the partition piece F, and with, the key levers D; the pin that receives the barrel being placed eccentrically with the hoop, and the hoop and the plate C revolving with each other, as described. I also claim the Inanner set forth of arranging and combining with the key levers DD the intermediate levers E E, the auxiliary levers H, and the bolt levers G, which are raised and lowered by said auxiliary levers— the whole of them having fulcrum pins, on which they rise and fall, and not operating as slides in a direct line; by which arrangement they are rendered more certain in their action. I claim the manner in which I have arranged and combined the auxil- . iary levers with the clawed talons g, the bolt levers G, and with the respective studs l, m, and m, so as to operate for the purpose and in the particular manner herein set forth. I do not claim the use of talons with claws to engage in notches, or teeth on slides; but I limit my claim to the special arrangement herein made known. , o I claim the manner of employing a latch, K, in combination with the bolt J, levers G, lifting-piece or, and the spring s, for the purpose of preventing the pushing back of the bolt when it is but partially shot out; the respective parts concerned in this operation being arranged and acting sub
