- Be'it known that I, JAMES, Ma'TAiibiga citizen of the United States, residin at Detroit, 1n the county of-WVayne and-tate-Of lxlichigan, have invented certain neW, and useful Improvements inLocksgrand I; do

hereby declare the following ,to be: afull, clear, and exact description :of the ;1;nventio1i,fsuch as will enable othersilskilledcin the art to which it appertainszto make and use the same. 7

' I A- further object This.v invention relates "to locks, 'and'aims to provide a lock of novel'rand'slmproved construction, and. using axscreivgthreaded' key for; releasing "the shackle or] similar member;

is the provision ofa lock mechanism which can: be contalned within a possibility ;of ethe -lock 1 being ---;'picked or opened Withoutthe aidof the required key. I

Another object is the provision .{fin the lockof a guard'ror, barrier 'awhich. prevents the operation of the 'lock for opening it, until such guard 0r ,barrier.is actuate'dby the key. V

.A still further, pi'ovision 'of such a lock embodyingtwogcorrelated move able parts, one, to engage the shackle or similarmember, and theother normallyoperable to prevent the first named ,Inemher fromlbeing moved to. releasing position, such members being controlled-by a key-having separate threaded or. equivalent portions for first, moving the second namedhmember inorder-that the firstnamed member can then be moved to releasing position. k Another object isithelj arovisiongof anovel key for operating the lock, embodying; in

'dependentlyroperable members, one-for pre+ paring the lock so that the other manipulated to open the lock;

can be With the foregoing and other objects in view, which will be apparentlas the descripr Y Y tion proceeds, the 'iinvention-resides in the construction and arrangement" of parts here inafter described: and claimed,;it being-{un derstood' that changes can be "made within the scope of 'jwhat is claimed'without de parting from thespirit of the-invention.
