Description
I. KEATH'l Locks.
Patented Dec. 17, 1872.
r DN vll - To all whom it may concern:
Be it known that I, JOSEPH KEATH, of Ash j Grove, in the county of Iroquois and State of Illinois, have invented a new and useful Improvement in Locks, of which the following is a specification:
a My invention consists of a series of bolts in two parts arranged for being sepa-rated after they are shot by a peculiar detaehing apparatus, so that the parts of the bolts whereon -the keys act may be moved without affecting the partsby which the door is secured, and the bolts cannot be withdrawn till the two parts are connected again. My invention also consists of a regulator combined with the bolts Vin a manner to readjust the bolts after being disarranged and confused to prevent the picking of the lock. t Figure 1 is a front elevation of the lock with f the front plate removed and part of one of the .bolts sectioned. Fig. 2 is a horizontal section. P Figs. 3, 4, and 5 represent the keys. Figs. 6, 7, `and 8 represent awl-shaped instruments, to 'Y j be used in connecting and disconnecting the bolts. Fig. 10, an elevation of the front plate j fof the lock. Fig. 11 is an elevation of the Y yplates which separate the bolts. Fig. 12 is an l. elevation of the back plate 5 and Figs. 13 to y f 18, inclusive, represent thetumblers in elevaa tion and plan views.
Similar letters of reference indicate corre- 1 Y spending parts.
A A1, and A2 represent the parts of a series 'of three bolts on which the keys act. B, B1, land B represent the parts which'project from the lock to fasten the door. rIhe parts A, A1, and A have each a hinged piece, C, pivoted tothe end next the parts B with a notch, D, which hooks upon. a cross bar or pin, E, on the B, &c., for-eon11ecting both parts of the "f boltstogether. These parts C swing laterally ontheir pivots to pass the bars or pins E for connecting and disconnecting the two parts. They are pushed back by the awl-shaped instruments F G H, one for each bolt, so arranged in' respect of its length that, when .pushed into the lock-case till the shoulder comes against the case, it deects the piece 0 ciently to pass the bar E, with which it engages.' The said pieces are pushed back again, and held in connection with the parts .'B, Sto., by springs H. The crossbars E exfj QUNTTEn STATES.

tend. from one to the other of the two prongs, J, between which the pivoted pieces U enter for engaging them, and the rods ofthe instrumentsfor pushing the pieces C ot the second and third bolts back also pass between these prongs. A stop-pin, K, on each of the parts t to arrange the bolts to have three movements,
two being imparted by one key and one by thel other. G1, O2, and G3 represent the keys. Each one has a stud or arm, o, for throwing the bolts, exactly alike in all respects, except as to length, in which they all differ. Each bolt has three notches, b d e, in which the arms of the keys work to throw it. In this example the notches of the front boltA-also, the second oneA1 are adjusted for using the keysO1 and C3, and those of the third bolt A2 are adjusted for keys O1 and G2.- N represents the tumbler for the front holt, O the tumbler for the middle bolt, and l? the one for the rear bolt. They are arranged in a case, Q, below the bolts, and have a stud-pin, R, for entering them to fasten the bolts when shot, in ease it is not desired to detach the two parts. Sufficient space is provided in the case Q to allow the tumblers the requisite movement for engaging and disengaging the bolts, and a spring, S, is provided under each to throw the pin into the hole when they coincide.
To lock the lock, begin with the front bolt,
usiugkey C1, whiehmoves the bolt outward one stage; then use key O3, moving it another stage; then use key 01 again, givingit the last outward movement; then detach the partO by the short instrument F, and throw the part A of the bolt back one sta-ge by key O1; then throw it back another stage by key O3; and, lastly, another stage by key O1. The tumblers are detached by the shanks ofthe keys,which press them down in the case Q. rIhe other bolts will be actuated in the saine way with the appropriate keys, which will be known by 2 resbala the marks f on the sides to indicate when they are inserted far enough for the pins or arms to enter the notches in the bolts. The different marks show the positions of the keys for the different bolts they are to act upon.
The' regulator consists of the cylinder T withconneeting-cords U and a key, V, Figi). rEhe cylinder is turned by the key to the right after the key G2 has been put in to detach all the tumblers, and when all the bolts are disconnected the cylinder, being turned as far to the right as it can go, will brin g all the bolts so they can be actuated properly for locking or unlocking. I
It will be seen that when the bolts are shot1 and the parts on which the keys act detached from the other parts, the lock cannot be unlocked even though that part of the case con tainingI the said parts acted on by the keys be blown oit'.
l propose to have holes in the lower edge ot" the case, so that powder poured in at the keykole for blowing up the lock will run through, to a space below.
Having` thus described my invention, claim as new and desire to secure by Letters Patent- 1. A series of bolts for a lock, constructed in two parts and arranged for disconnecting the parts acted upon by the keys from the parts which lock the door after being shot, substantially as specified.
2. The combination, with a series ci lockbolts constructed and arranged in two parts for being,I disconnected as described, of a regulator, substantially as speciied.
