Specification of Letters Patent.
ALARM, SIGNALING, AND CONTROLLING DEVICE.
Patented Nov. 11, 1913.
Original application filed October 17, 1911, Serial No. 655,163. Divided and this application filed November To all whom it may concern Be it known that I, EMIL HEINRICH BOOK, en neer, a subject of the German Emperor, an residing at 4 Nachodstrasse, Berlin, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Alarm, Signaling, and Controlling De- ..vices, of which the following is a specification.
This invention relates in general to alarm,
' signaling and controlling devices, and in particular to the combinatiomwith such devices, of a. vibration contact, as is more fully T described hereinafter.
This application is a division of application NO. 655,163, filed Oct. 17th, 1911.
. In order to make my invention more clear, I I refer to the accompanying drawing, in
which similar letters denote similar parts throughout the'several views, and in which:
.Figure l-is a dlagrammatical representation ofone form of construction of my improved device, ard Fig. 2 is a similar representation of a slightly modified form of construction, th box being omittedQ I 1 Referring to Fig. 1, the casing or box 36 is closed by moms of the lid 37 The electric line is markel and passes through the needle 38, the ring 39, the rod 41 and the stand-12. As soon as a vibration is produced, the needle 38 which is secured to an elastically suspended weight 161, will intermittently move away from the interior wall of ring 39. In consequence thereof the cur rent flow ng through line 40 will be intermittently interrupted. The interruption of the current may be utilized to deenergize a closed circuit relay, thereby allowing its armature to drop, which in turn may control an alarm device in any well known manner. It shall be hereinafter described how this is effected accordin' to the present invention. The needle 38wi 1 be generally resting elastically against-the inside wall of ring 39. This ring 39 can be horizontally displaced by means of a rod 41 adjustable in a stand 42, so that the needle 38 will bear more or less tightly against the inner side of ring 39;
it i 5 evident that the needle will answer more Serial No. 730,307.
quickly to any vibrations, the more lightly it is pressed against the inside of the ring; By displacingthe rod 41 in the stand 42 the sensitiveness of the device may be regulated at will. The. box 36 is now simply placed on an article to be guarded, say on a safe. If it is now attempted to forcibly open the safe the vibrations caused thereby will be transmitted to the box and cause the needle i 8 todvlbrate, whereby t e alarm will be reease fWhereas in Fig. 1 the alarnris actuated by the breaking of a closed circuit, the provision is made in Fig. 2, that the needle 38 will on vibrating not only leave the ring 39 but also come in contact with a small disk 162, and thus intermittently close a line 165. By the intermittent closingof the circuit 165 a continuous bell signal arranged at another point will be operated, as this is also employed with the hereinafter controlling device. The present vibration contact device is a particularly accurately acting one and this is the consequence of the fact, that the elastically suspended weight 161 will vibrate but slightly under the influence of slight vibrations, but that these vibrations of the weight will be greatly amplified by the length of the needle 38. It must be further seen that the mass of the needle 38 should be but very small with regard to the mass of the weight 161.
Having now described my invention what I desire to secure by a Patent of the United States is:
1. In a device of the class described,
in combination, an elastically suspended Weight, a needle of light mass secured there trical contact member positioned adjacent In testimony whereof I have signed my the lower end of said needle, said needle name to this specification in the presence of being adapted to vibrate relatively to said two subscribing witnesses.
