To'aZZiw/wm it may concern:

Be it known that I, R ooLF SALAMON} a citizen of Yugoslavia, residin at New-York city, in the "county of New ork and State of New York, have invented certain new and; useful Improvements 1n ,VVmdow Locks and" Alarms; of which fication.

the following :is a speci- This inventlon; has relation to window- 19 looks and has for an object to provide acom-y bined window lock andalarm device, intended for application to the sashes ofya window and' including means' for locking the sashes together in any relatively. adjusted position, and for locking one of the sashes I to the window frame, whereby they maybe immovably held, thus permitting the sashes to belocked in an openposition to secure ventilation. Y

2 Another object of the invention is to provide a combined window'lock and alarm de.-'

vice having the Characteristics above set forth and including in addition thereto an 7 alarm mechanism operatively associated with. the locking devices sothat in the event that I oneorthe other of the. sashes are moved inanatteinpt to raise or lower the same the alarm mechanism will be actuated to sounda signal. 1

In addition to the foregoing this invention comprehends improvements in the details of construction and arrangement of'parts to I be hereinafter described and particularly set forth in the appended claim.

In the accompanying drawings in which similar and corresponding partsarefdes1gnated by thesame characters of reference throughout the several views in which they appear.

Figure 1 is a view in vertical section through a combined window lock and alarm device constructed in accordance with my invention and illustrating the meeting edges of the sashes in edge view.

Fig. 2 is a view thereof tion.

Figure 3 is a vice and Figure 4 is a detail view in section.

With reference to the drawings, 10 indicates the lower sash and 11 the upper sash.

I Appliedto the front face of the upper sash is a vertical rail 12having a plurality of vertically spaced square openings 13 therein. .The window frame is indicated at 14 and secured to the side face thereof is a vertical in vertical secviewin top plan of the de- .rail-1'5'lilrewise having. openings lti formedtherein in spaced relation. vMounted uponi/ thetop'edge ofthe lower. sash 1 0 is a plate 17 having a sleeve 18ffor1n'ed thereinzextend-ii Q ing transversely. off thesash and designed to receivea threaded'rod 19. .iTo'the: inner end z of the rod there. is secured a square block 20.

which is provided witha reducedlextension '-21 enteringan opening infthe rod'19fand fheld therein against dislodgement but'in af mannerto permitrotation of the .rod 19 and.

" The devicefurther consists of rectan'gu- J larI casing 22 which is secured-to the front 5 face. of :the lowenSash and in'which. thereis mountedv a horizontal locking bar 23'designed for sliding movement andadaptedzto enter one :of-the openings 16, of the .rail 15.-= The,- block is shifted by:'mea-ns,of the pinion 2 L which is mounted-upon a rod 25"and,which engages teeth formedin the lower edge of,- i I the bar 23. .-It will be noted that the outer end of the bar' l s adapted for. slight vertical oscillation for" 1a, -purpose to' 'be presently.

To one endof said lever 35 there is connected a link 36 which in turn is pivotally connected to an arm 37 pivotally mounted within the casingand carrying at its outer end a hammer 38 designed to strike a gong 39.
