i To all whom it mcy concern:

Be it known that We, JOHN P.' WILLIAMS and HERMANN HUHN, both citizens of the United States, and residents of New York, in the county and State of New or Gratings, of `which lthe following is a specification. i Y l n This invention relates to that class of electrically-protected grille-.work or gratings which 'are adapted for use at or in doors, windows or other openings of abuilding or structure to be protected, and which operate, vwhen an attack is made upon their' parts, to close van electric circuit and cause an alarm tobegiven.' i

vOur improvements are adapted for effective use upon any structure to be protected,

v=or in the construction of prison cells to prevent prisoners from making escape without giving an' alarmp, or the inventlon may be applied tothe doors and wmdows ot' a prlson lfor alike purpose.

The object', of our invention is to provide a'n improved protective grille-Work or grateffectlve ing or cutting lthe "bars, and which will furthermore possess advantages in point of simplicity, strength, positive operation and Thecomponent parts of our invention are assembled, and electrical connections made, in such a manner that an ,attack in any way disturbing the normal status of the construcerethrough, especially by bending, clap,k pmg, or cutting the bars, will cause an electrilcircuitto be instantly closed and an alarm given.

A structure composed ofv our electricallyprotected grille-work such as a safe or vault or storage compartment.

In the drawings-Figure 1 is an elevation. showing our improved electri :ally-protected grille-work or grating applied to a window opening of a building and arranged to ol struct said opening and prevent lpassage York, have invented certain new yand usefullmprovef ments in Electrically-Protected Grrille-VVorkk or grating may lbe, 'built to surround any olncct to be. protected,

Referring` to the drawings, our electrically-protected. grille-work --or grating is shown 'at A, applied to a window opening, B, of a building, C. i g

They improved grille-worker grating, in the type of construction `herein shown, come prises top and bottom supporting barsor members, l1 and Q, and vertlcal bars or members, 3,. the parts ofthe structure being vas.- sernbled and electrified in such a .manner that an alarm circuit, forming a part thereiof, will be operated to sound an'alarm in case an effort is inade to gain entrance .throughv the structure by bending, clamping,

sawing, cutting or otherwise attacking the same. The top and bottom supporting members 1 and 2 are similar in construct-ion and are composed of outer and inner channel Corresponding parts in all; the figures are members, and 5, spaced apart throughout and insulated one from the other, said channel members being of metal or other 'con-` ducting material. The outer channel members 1 consist. ot' central webs, 6, having apertures, T, and spaced flanges, 8, lover which caps or co\'ers S), are placed andsecured. This constructitm provideschambers, 10, in which are housed the inner channel members 5, which comprise central webs` 11,'having apertures, 19., therein and spaced flanges, 14, thereon.

The vertical bars or members 3 of the structure are ot` metal' or other conducting 4material and comprise outer tubular bars, 15, preferalily reduced at the endsthereof,

tas at 1G, to,snugly tit into the apertures 7 of the uebs (3 ot' the outer channel members 4, and inner bars, 17, spaced from the tub'ular bars'l throughout and insulated therefrom by sleeves, 1S, ot fiber or other insu-v lating material which are seated over the ends Yof the inner bars '17 and in the ends oi? the outer tubular bars 15, as shown in Fig. 9. The 'insulating sleeves 18 are proa ably ,,copiposcdrfentii'e a saw, file or otl at 23'and 24, to th vided with annular flanges, 19, which, when the parts are relatively assen'ivbled', lie-betweentlie central-webs o' and `ll of the outer and inner channel members 4 and 5 respecf tively,and insulate one fromthe other.v Tlle'- innei" bars l'hmay be solid, asherein shown,l or they may be tubular if desired. The ends of Said bars 1T aretlhreaded, vas Q0, ai'i'd are passed through the apertures 12 in the ivebsi itl4 of the ,inner Achannel members 5, and' nits, Q1, are threaded ends to securelyY bind the structure together, as will be readily understood Cross pins. are provii-led tans'yei'scly at une enilof the innerbars 17 '(or at both ends, if desired), for thef purpose of makingr contactwitli thes'iia'reil llanges 8 of the outer channel memberl -l-,- io close an alarm circuit, slioiildatliey inner liar l be'rotaied by theaction ol. asini/,tile on other instrumentI in anattempt to sever the same. 4 t Y EThe structure above described, is piefihff ly 'ot conducting ma-l tei-iai, except the insulating sleeves iti. iInr the preferred 'electrical 5circuit. arg rangement, vthe foutei" and inner channel members tand 5. are' respectively' co'i`i`iieoted,
