Application ined` october misas.' serial No. 64,950.. i l

This invention relates toV burglar-alarms for use in connection with doors and windows of buildings,A one 01" the 'objects of they i invention be-ing toprovide a simple structure 5 of this characterwhich can be installed readily and vwhich does not.` require the use oi electric current. p f

A further object is to provide a device which, while in use, will sound an 'alarm when a window or door is opened.

A still further object is to provide ap-4 v paratus ofthis character which can be constructed readily and will not easilyl get out of order. i v With the foregoing and other obJects'in view which will appear as the description proceeds, the invention resides in they cornbination and arrangement of parts and in the details of construction hereinafter de? `scribed and claimed, it being understood that changes inthe preciseembodiment 'of the invention herein disclosed may be made'v within the scope of what is claimed without departing from the spirit of lthe invention.

' In the accompanying drawing the preferred form of the yinvention has been shown. f

In said drawings l Figure 1v is a Vfront elevation showing the alarm applied to a window,y a portion of the bracket ofthe alarm being shownin section. v y Figure Q, is a side elevation of thebracket portionof-A the alarm and the parts mounted thereon. l y Figure 3 is a plan view of the structure shown in'Figure 2. i

Referring to the figures by characters of reference 1 designates -a base adapted to be mounted on a bracket SZ which can be attached to the upper portion of a window frame or door frame. stance a window 'frame'hasbeen shownat F lwith the 6 the freev end 'of which is slotted as vat?,` so as vto..,.strad'd1e andslidably engagea threadedgstem 8 secured to` and extending upwardly'frem the base 1e Qn this stern` is In the present -in-.

through an aperture. 12 in the base 1. This suitably located on the frameF and the endotfthe cord 'is attached-tothev window sash.

*A cord indicated Vat 11 is connected at oney v end tothe lever 6 and extends .downwardly r- 160 ycord isthen guided under a guide pulley 13 IV or other .movablestructure v i l Obviously, with the vparts attached to the window as shownthe movement of the winloosely engaging a portion of the cord 11.

This cord can beavery fine but strong one or can be in the form of a iine wire which would not 'be visible through the window under ordinary conditions. Thus, should one of the lights be removed from the sash any one attempting', to pass through the same or toreach therethrough rwould necessarily press against the cord 14 so that it would pull through the hook 16 uponcord 11 and thussound tliealarm. p

Whilethe structurelias been shown assembled'with la window it listo be understood that theI same'could also be applied to a door.` Furthermore a single'bell could `be coupledto a series of'windows or doors so that the opening of any one of them would result in thev sounding-of the alarm.

`It is toy be understoody that each time the cord llis pulled downwardly lever, 6v will compress spring 9 so that-when the' cord is released the leverwill be returned to its normal or raisedposition by the spring.y

alarm kherein described `could bevused vfor purposes other than those heretofore set,4 orth.` For [example the operating cord could be extended toI anlautomobile located outside of a buildingor to the doorsor windows of an out building.` Thus the alarm would be sounded should an attempt be It is to be understood of 'course that the f ion made to 'removethe automoble'or to enterv v the out building.
