JOHN ISRAEL, OF DAYTON, OHIO.
BURGLAR-ALARNI.
SPECIFICATION forming part of Letters Patent No. 224,017, dated February 3, 1880.
` Application madonna 6,' 1879.
To all whom it may concern: i
Be it known that I, JOHN ISRAEL, of Dayton, in the county of Montgomery and State of Ohio, have invented certain newand useful Improvements in Burglar-Alarms, of which the following is a specification.
My invention relates to that class of burglaralarms which are applied to doors and windows to guard them, as exemplied in Letters Patent of the United States No. 193,002, granted to me July l0, 1877.
In the accompanying drawings, Figure l is a front elevation, and Fig. 2 is a side elevation, of my apparatus.
The percussion-tube A, its plunger, and the match-holder a are similar in construction to those shown in my patent `above mentioned, and are mounted upon the lamp-cylinder, asin said patent. The lamp-cylinderB is mounted upon a foot or bracket, b, which bends or projects outward, and is secured upon a carryingplate, O. This cylinder has a filling-hole, b, which is tightly closed by a screw-plug, b. The wick-tube D is made conical in shape, with the smaller endupward, and hasatightlyfitting conical cover, d, secured to a chain, the other end of which is fastened to the matchholder a.
A suitable reflector, E, is carried by an arm, e, pivotedto the carrying-plate back of the lamp-cylinder, and can be swung around its pivot, so as to be out of the way when not in use.
An alarm-bell, F, is secured upon the carrying-plate just below the lamp-cylinder, and is sounded by a simple clock-work and bellclapper of ordinary construction. The bell F is screwed upon the windingpost, so that the clock-work can be wound up by simply turning the bell.
A tripping rock-shaft, K, is secured upon the carrying-plate in -eyes k. One end, 7c', of this shaft is turned up and looped over the hammer or plunger of the percussion-tube, and the other, k2, is turned up so as to engage with the trigger j of the alarm-bell mechanism.
The operation of my improved burglaralarm, when organized as above described, is as follows: The apparatus is to be so secured upon the jamb of a door or window that the hammer ofthe percussion-tube, when set, will be tripped by any movement of the same.
The hammer being set, the rock-shaft turned outward so that its end k2 will engage with the trigger of the alarm-bell, and the bell being properly wound, should the hammer be tripped from any cause it will plunge forward, explode the cap, ignite the match and lamp, and trip the alarm mechanism of the bell by means of the rock-shaft.
In addition to the tripping rock-shaft above mentioned, I provide a tri pping-shaft, L, which is turned up at each end, one of which ends serves as a handle, and the other, Z, engages with the trigger of the alarm-bell mechanism, so that the alarm-bell may be sounded and stopped simply by rocking this shaft back'and forth.
The endl, which engages with the alarmbell trigger, is turned up so as to move in the same path with the end 7a2 of the rock-shaft, r
so that should it be desired to use the bell as a call-bell when the entire alarm is set, it will only be necessary to rock the shaft L, the end l of which will move the end k2 of the rockshaft out of engagement with the trigger without exploding the cap. By this means I am enabled to utilize the apparatus during the hours of the day as an ordinary call-bell.
The manner of applying this apparatus to doors and windows is well understood, and need not, therefore, be described.
By dispensing with the lamp and alarm-bell mechanism and simply using the/percussioncap as an alarm, and providing a suitable trip to be used in connection therewith, I produce a pocket-alarm for travelers 'which can be temporarily secured upon a door or window.
Having thus described my invention, what I claim as new, and desire to secure by Let'- ters Patent, is
l. The combination of the plunger, the rockshaft, and the alarmbell mechanism, substantially as described.
2. The combination of the rock-shaft, the alarm-bell mechanism, and the tripping-shaft L, whereby the alarm-bell can be utilized asa calLbell, substantially as described.
`In testimony whereof I have hereunto subscribed my name.
JOHN ISRAEL.
