IMPROVEMENT IN BURGLAR-ALARM LOCKS.

Specification forming part of Letters Patent No. 20,333, dated May, 1858.

To all whom it may concern:

Bc it known that I, ADDISON COREY, of the town of Gasstown, in the county of Miami and State of Ohio, have invented anew and useful Improvement ona Door-Lockwith Attachvmerits5-and Ido hereby declare that the following is a full and exact description thereof, ref;`

voltaopistol, for the better protection .of perJ sons and propertyfrom burglars entering their apartments while asleep, giving warning of the presence of the same, that they may be taken and secured. o

To enable others skilled in the art to make and use my invention I will proceed' to describe its construction and operation.

A lock may be made of any size or pattern desired, with theoutside knob, A, Plate I, divided into two sections and insulated, so that the par which works the latch will screw tightly into one of these parts, that it may be taken off and another putin its place whenever desired.

The knob 'may be made of brass or other metal, and insulated with' gum-shellac or any other substance accomplishing 4the same; or mineral or other kinds of knobs may be constructed with two pieces of metal embedded in them as ornaments orv otherwise, and con nected as hereinafter described.

A ferrule or ring, a, is made to slide on the l knob at c, and another, `b, to slide on the bar of the knob, these ferrules being made of wood, ivory, bone, or some nonconductin,g,` substance.

'These two pieces thus put on and the knob screwed on tightly brings one part of the knob in connection with the bar and the other with an insulated wire, d e, passing along in a groove'in the har d and cemented in its place with gum-shellac, and terminating with an in sulated conducting-cord, As, fastened to an insulated metal piece inserted in the upper part of the lockframe or otherwise, as 'at s.

The lock is provided with a lever, p, operated on by aspring and fastened o n the righthand end of the boltj` and working on a piu at the lower end,so that, taking hold of the top of the lever 1J and drawing it back, the. bolt f will draw back and catch in the notch e, and then it is set. Now, if the knobbe turned either way, the two arms at t will press on'the wart at u or u and bear the boltfdown out of the notch c, and allow the spring to throw the leverp forward with ajerk; and, also, the lever t, having two horns, o o,`which, it' pressed .either up or downrwll pressoneither of the two pins in the piece h, which turns on the center pin, and draw the bolt f down out of the Y notch e, as before, by thearm w,- and, again,

if a key be inserted which is not provided with The piece l: is fastened to the boltj so as to work up and down, but not lengthwise with regard to the bolt, 'and the bolt j is to throw this point k out or in the key-circle, so that another key will not pass when the point is in the circle of the key, and the key q q having two notches so arranged as to pass over the pointltando o, and unlock the bolt g and throw the boltj hack and bring the point k out of the way of the main key, which unlocks the bolt m. The bolt ghas two pins in it to work against the upright arm of l, so that after bolt m is locked g will lock and move l into the notch at m and hold the main bolt m fast until g is unlocked. There is also asliding button,:r, Plate II, fastened to the bolt g, that it maybe fastened fromthe inside, and no key can unlock it,which secures the boltm from being unlocked. 't is the piece or tumbler which slides on the bar d and works the latch.

im anda are the bolt andlatch ofpa common lock, The boltj' iszlplaced by the side of n, q by the side of m, and j bythe side of i, as will be seen in the lock.' There are two keys to be used with the lock,the one to llock and unlock the bolt g with its two notches, as seen at q g,

and the other to lock and unlock the bolt m, and the keys can be varied in different locks. The attachments are, B, a galvanic battery, arranged with a clamp and treadle, y, Plate II, to hold the galvanic plates over and out of the solution, which treadle is to be connected to the lever p in the lock, so that when the knob is turned or a key or wire inserted which may will instantly light up the room, and a voltaic pistol, M, is to be attached, when desired, in order to scare the robbers away when too timid to go out and take them. Any or all of these attachments may be used at the same time.

What I claim as my invention, and desire 'to secure by Letters Patent, is I The application to door-locks of theinsulated knob, these extra bolts, levers, and springs in this arrangement with any lock, and these dseveral galvanic attachments in combination with the lock, as herein described, or any others substantially the same, and which will produce the intended effect.v
