RUSSELLBUNKER, or HUDSON, wiSooNSI'N.'
i Letters Patent No. 62,604, 'dated Marck 5, 1867.
IMPROVED BURGLAR LRM.
To ALL WHoM IT MAY coNcERN:
Be it known that I, RUSSELL BUNKnn, of Hudsornin' the county of St. Croix, and State .of Wisconsin, have invented a new and improved Burglar Alarm; and I do hereby declare that the following isla Tull, clear, and exact description thereof, reference being had to the accompanying drawings, making apart of this specification, in whichn-A v Figure 1 is a viewo` the inside of a portion of a door 'showing the alarm applied to the door-latch. .Figure 2 is`a similar view, showing'the manner of connectingr the releasing pawl ofthe alarm to the tumbler on the stem of the door-knob.
Figure 3 isa top view of iig. 2.
VSimilar letters' of reference indicate corresponding parts in the three figures.
This inventionjs designed to afford a simple and efficient safeguard against the entrance of thieves into a' house or room through the door thereof, by applying to the inside of a door a train of wheel-work, which is acted upon by a spring, similar to a clock spring, for ringing a bell; such eontrivunco being connected to the latch oi' the door in s uchmanncr that the slightest movement ofthe door-knob will cause an alarm to bev struck,
saidmecha-nism being provided with a pawhlwhich can be set so as to stop the movement of the wheel-vrork when the alarm is not requircdto act, all as vwill he hereinafter described.
To enable others skilled in the art to understand my invention, I will describe its construction and operation.
In the accompanying drawings, represents a portion of a door to which my invention is applied Bis the jamb or frame of this door, and (i'isy Va latch-plate containing a common sliding spring-latch, a, which catches in the latch-guard C on the-door-fraine B. D is the door-knob, and D its stem, which oscillatcs the two tumblers b b, shown in iig. 2; and thus moves the latch back, whether the knob be moved toward the right or the left. Two cords, c c, are connected to the ends ofthe tumblers b b, pass through holes which are made through the latch-plate C, and connected to the long arni of 'c pawl or trigger, d, as shown in figs. 1 and This ltrigger .d is pivoted 1to the 'doorv at a suitable distance beliindthe latch-plate, and in such relation to the scapewl'ieel' c of a train of Wheel-work, that this trigger can beset so as to arrest the .movement of said wheel when-the wheel-'work spring z' is wound up, as represented in iig. 1. When the door-knob D isturned very slightly, the tumblers, one or the other,vvrill act upon the trigger d through' the medium of the cords c, and nievev this trigger so as' to release the lscape-wheel e. El-1e bell, F, is secured fast to Athe door A, and struck by means of a hammer, it', the rod la of which is secured firmly to the oscillating staff of `the pallets g, so that when the scape-wheel is free to turn,an'd is actuated by the spring i, thehammer h will continue to strikethe'bell until the force of saidl spring becomes exhausted. The wheel-Weth which I have represented islike the striking-works of a clock;
its frame, E, is'rnily securedy to the door A, and its spring can bc wound 'up by applying a' key to the statt j, around which saidA spring isywound.V Abovetho cscupement wheel e and pallets g, is, a stop,'f, which is a short bont strip pivoted to the. door, and intended for'prevlezrting the portiong from vibrating and releasing the scapewhool when the spring i is wound up, and the trigger d is released from this scape-wheel. Therefore,` when the spring'z' is wound up,`and it is desirable to keep it thus, and the stopfis` down upon the portion g', the knob of thc door can-be used freely without striking the alnrrn.l When it is desired to have the alarm struck, by a movement of the knob D the s'topfis moved from the portion @es shown in igs..1 and 2, and the trigger d isset, so as to arrest-the escapomont wheel e, as shown in fig. 1. i With the parts adjusted as indicated in fig. 2, the hammer fr will strike the bell until the spring i ceases to act.- When the trigger d is thus released 'from its wheel e, no movement of the knob D will bring it back again to its former position, as both cords, c c`,`connccting it withthe tumblcrs b b,'arc attached te its long arm, as shown.' It wili be seen from the above description that the -alerm contrivan'ces are very simple andnot liable to derangeinent' nor' failure, and that they can be conveniently applied to the latch-knob oi' almost/every door. i
Havingdescrib'od my invention, what I clainlias new, ud desire-to securcrby. Letters Patent, is- Combining an alarin mechanism,substantially as described, with'hI door-latch, in such manner that by moving such latch the cord c will release the trigger d from" the 'scape-wheel, and cause the alarm to strike, substantially as heroin set i'ortll.
