BUBGLAR 'ALARM.

Be it known that we, -WILLIAM D. Htn PETI'I and CHARLES C. HanTzoon. citizens of the United States, residingat Monroe, in the parish of Ouachita and State of Louisiana, have invented new and useful Improvements in Burglar-Alarms, of which the followingis a specification.

This invention relates to burglar alarms, the object of the invention being to provide a simple, reliable and effective device foraudibly indicating when a window sash or Specification of Letters Patent.

Application filed June 19, 1912.

' minal door has been opened, the'devi'ce being applicable to the ordinary sash arrangement used in windows, and being applied easily by any unskilled person.

A further object of the invention is to provide means whereby during the day time the operativeparts of the alarm may be thrown out of operative relation to each. other, so that the sashes may be raised. and lowered, without interfering wit-h thealarm mechanism.

Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed outin the'claims hereuntoappended. I

In the drawings: Figure 1 is a vertical cross section through themeeting rails of a pair of sashes, showing the alarm applied thereto. Fig. 2 is a View in elevation of the same. Fig. 3 is an enlarged detail view, showing the main parts of the alarm tripping mechanism in their relation to each other. Fig. 4 is a detail view of the hinged and folding lug.

Referring to the drawings, 1 designates the bottom rail of the upper sash, and 2 the top rail of the lower sash.

The burglar alarm embodies a base plate 3. provided with any suitable number otj holes c adapted to receive screws or like, fasteners, whereby said plate is secured to the inner face of the meeting rail 2 of the lower sash, in a manner illustrated in Figs.

1 and 2; Extending outwardly from the l base plate 3 is the post l of a rotary hell 5, 5

containing suitable mechanism, such as a hammer and actuating IllOCllEllllHll therefor, 5 whereby when he hell released and 11- l lowed to he revolved by the usual spring. the l bel is sounded. Extending upwardly from Patented July 22, 1913-. eel-n1 No. raises.

the bell a plunger trip or rod 6 which, when pressed downward or toward the center, of the bell. releases the mechanism which causes the bell to be sounded. Extending outwardly from the top of the plate 3 is a bracket 7 having an upwardly extending ter portion 8, upon which is pivotally mounted, at 9, a sleeve 10, through which passes a lever 11, the same being threaded to receive one or'more nuts 12 and 13, by means of which the lever 11 may be adjusted 'in the direction ofits length, fora purpose which will hereinafter appear. The bracket 7 is also provided with a guide opening 14, through wh ch the plunger trip 6 is arranged "to slide. as shown in Fig. 1, said trip being normally upheld hymeans of a coiled spring- 15 which. extends around the plunger trip (3 and is interposed between the bracket 7 and a head or shoulder 16 at the upper end of the plunger rod. The lever 11 rests upon thehead 16 of the plunger, so that when said lever is depressed, the plunger is correspondingly depressed, thereby'releasing the mechanisln which actuates the bell Connected to the bottom rail 1. of the upper sash is an outwardly projecting lug 17 which cooper ates with the extremity of the lever 11, for depressing thelever, either when the uppef or lower sash is opened.

.In the preferred embodimentof this invention, the lug 17 is hinged at 18 to a bracket or attaching plate 19secured to the rail 1 of the upper sash, as by this arrangement the lug 17 may be folded back against the sash or into arecess in the face of the sash, so as to be out of the path of the lever 11, thus enabling the device to be thrown out ofuse in the day time. Furthermore, the lever ll may be moved outward in the direction of its length. so as to carry the inner end thereof out of the path of move' ment of the lug 17, even when it is in a projecting position, as shown in. Fig. 1. Either of the adjustmentsreferred to will throw the device out of operation in the day time. when it not needed. and either one of said elements will enable the device to be thrown into operation, when desired. If desired. a set screw 20 may be used for fixing the adjustment of the lever 11 in the l CQ\'O 10.

What is claimed is: I

1 ln a burglar alarm. a rotary bell, a

,plate on whicn said bell is supported, a

bracket on said plate, a lever fulerumed on said bracket,- a plunger arranged to be operated by said lever and adapted to trip the bell actuating Inechanism, anda lug with which the lever isj'adapt'ed to come into conplate on-which said bell is supported, a

bracket on said plate, a lever fulcrumed on sand bracket, means for adgusting said lever in the directionv of its length, a plunger arranged to be operated by said lever and 15 adapted to trip the bell actuating mechanism, and a lug with which the lever is adapted to come into eontact upon movement of the sash in connection with which the alarm is used.

In testimony whereof we aifix our signatures 1n presence of two witnesses.
