To all wwnt 17m/y concern,.- l

Be it known that l, CLYDE COLMAN, a citizen of tie United States of America, and a resideutoi Chicago, in the conutyof Cook and 5 State oi' Iliinois, have invented certain new -and useful improvements in Burglar-Alarm Systems, of which the following is a specification. Y The presentin ven tion relates to au electric Io protective system against'burglars, and more particularlyzto-that class of sn'chsystems inV which the alarmmechanism is located within a guarded-structure, an example of which may be foundfin Reissue Letters Patent No. "vr r; 1l,626,to Coleman, Deane, and Donnell, dated August 17, 1897. f The objectsof the presentimprovements areas follows: iirst, to provide a simple, dubranleI and eiective means for preventing aczo 4cess t`o the alarm mechanism through the sonndmpassagemthe alarm strucf" ture with apnimrsemf disabling or the destruction of suchalarm mechanism,and which :means in the simpler form of the present in- 'ention involves an electrical barrier inter osed betweenthe mechanical barrier and thev alarm mechanism and in the more advanced orm of the `presentinvention the-interposiion of such 'electrical barrier between a duv'lieate arrangement of' the mechanical bar- "t'ne innermost mechanical barrier must be passed after the destruction of the electricall barrier before the alarm mechanism can be 1 which'such alarm mechanism Will be operative beforeit lcan be lreached through such nner-most mechanical barrier, all as will herenafter more'fully appear, and be more particnlarly'pointed out in the claims; second,

,4 forsuch guarded structures for alarms andother allied .uses that is very sen-- "structure-or the structures adjacent thereto;

third,- to provide in connection witnsuch structu re,apertredfor the emission of sound,

Agctempt is made to u1 ufle the alarm mechanism riers in front of the alarm mechanism, so that l reached, thus affording an interval of time in' to provide' a simple and efficient form of elecs itive to .anyvnnautliorizeddisturbance in its'v l--parts in 'the several views.
