THOMAS P. SINK, 0F FAIRTON,NEW JERSEY.
Letters. Patent No. 109,954, dated December 6, 1870.
IMPRQVEMENT IN ALARM-LOCKS.
The Schedule referred to in these Letters Patent and making paxt of the lame.
To all whom 'it may concer-n.
Be it known that I,` THOMAS P. SINK, of Fairton, in thel county of Cumberland and State of New' Jersey, have invented an Alarm Door-Lock; and I do hereby .declare the following to be a full and correct; description ofthe same, reference being had totheaccompanying drawing, in which- Alock with two gun-barrels, one of which will be discharged by the insertion of a key, and the other by the shooting of the lock-bolt when properly arranged, so as to operate as a burglar-alarm.
a a indicate the gun-lock hammers.
b b, the door-lock bolt.
c c is a key-trigger.`
d d is a trigger with an alarm-wire.` v e e show a shoulder of the lock-bolt.
ff are the gun-barrels g g are the hammer springs.
h, the bolt-dog.
i e is the alarm-wire.
The object of this invention is to construct a door- .lock of the usual shape and size with gun-barrels that can be readily made use of when required as an alarm.
" The object of the receiver, as shown at g. 4, isto prevent the wad of the charge from striking the door; itis also intended to connect this receiver with an alarm-bell, if needed.
The ltrigger c c is' made to cover the key-hole when the hammer is cooked, and thereby operates the gunlock when anything enters the key-hole. y
The trigger d ll is made to operate by the shoulder e otl the lock-bolt b, and also by the alarm-wire 'i e'.
It will be seen, by the drawing herewith, that the trigger c, when the gun-lock is cocked, presents to the key-hole a bevel surface, so that when the key orV l pick-lock enters the key-hole it cornes in contact with the bevel of' the trigger, and it slides. sidewise as the key is pushed against it. By this means it springs the gun-lock before the key comes in contact with the bolt of the door-lock, and by this means the alarm will be
