Specification of Letters Patent.
"sweeten-atelier; anntocn ma WINDOWS.
Patented July 2, ate;
Application filed Mann e, 1am. fierim No. 549,315.
- lowing is a specification.
- My invention relates to improvements in burglar alarrns for windows, and it pertains w mere especially, among other things, 1st, to,
I erence to the accompanying the. device" for automatically starting the alarm signal when either one a'pair of window sash is raised or lowered, and find, to the device for simultaneously locking the twosashes of -a windriw together as' the alarm signal is sounded.
My intention is further explained by rel drawings, in
wl1ich V l igurev 1 represents a side view ofa' portion of a windo u'ovided with my C0111? bined signal alarm and lock, and Fig. 2 is a front View of the device shown Fig. 1.
Like parts are represented by the sauic reference numerals in both views.
1 represents the upper and 2 window-sash. I
3 is a signal bell. The bell 8 is or. ordithe lower nary construction, such for example, as those known as spring actuated bicycle signal bells, the spring of which, when wound up and released, causes a hammer to vibi ate rapidly against the bell. 4: is a push button, which is connected with the releasing inechanisrn of the signal bell, whereby as said push button is-moved toward the bell, the alarm signal will be released and the alarm will be sounded until the actuating mechanism of the signal has run down. The bell 3 is provided with a supporting bracket- 5, by which it is rigidly connected with the upper rail 6 of the lower window sash. d
7 are bracket retaining screws.- l
8 is a locking bar, which is slidably supported from the bracket-5 in apertures-9, 9, and is adapted to yieldingly-bear at its 1nner end against the vertical plate it). The vertical plate 10 is rigidly secured tothe front surface of the upper sash '1 by a plurality of screws 11 and is provided with a plural ity of apertures 12 located'at short intervals apart for the reception of the inner end of said actuating bar. The har 3 is provided with a. trlthsv-ersely' arranged'pin 13,- which seryes as a stop to the spiral spring 14, said spi'mg" libeing interposed between said pin and the-vertical member 15 of said bracket 5, whereby said actuating bar 8 is yieldingly retained, asstate'd, against thevertical plate 10, and w icreby-saidbar is forced into the apertures .12, as soon as it is brought in trontof the same. Thus it will be (ibvious that when the lowersash is raised, or the apertures 12 will be caused to rhgistenwit-h each other," when said. bar 8 will be thrown by the recoil or" saidspring into one of said apertures, whereby the-wimlow sash will-he locked. Theouler end of the bar '8 is provided with an upwardly and outwardly inclinedbearing surface 16, which is retained in contact with the push button a of said signal bell, whereby as said locking bar S is thrown into the locking positimrwith the upper sash, as stated,sa id push button it will be forced inwardly, whereby the actuating spring of the signal bell will be released and the'signal bellwillrbe sounded, as stated. 1t is obvious that while the platev lOlis preferably-used to prevent wear and friction of the sash, such plate may be dispensed with, in which case, the actuating bar will bear directly against the front surface of the sash and-will be'thrown by the recoil-lot said. spring into the holes l? of the saslnjwhich are formed beneath the apertures 12 of said plate. I It will be understood that'the front or protruding endof the locking bar 8 is curved upwardly terininating on a. higher plane than its inner end in sucha manner that as it is thrown forwardly by the recoil ment with the sash, its upper edge is adapted to yieldingly bear against the lower end' of the push button, whereby said push button will lOG'HIOVGCl upwardly, thereby causingthe signal bell 3 to be sounded.-
Having thus described my invention,what I claim as new, and desire to secure'hy Lett-ers Patent, is
l. Thecombination' of a pair of window sashes, a signal bell provided with a push button connected with the lower member ol' said sash, a locking bar connected with said sash,- means for retaining saidbar in yielding contact with said push button and the "upper sash of said pair, said upper sash beof the spiral spring 14: into locking engageupper sash lowered, said-locking bar 8 and ing PIOVidGdWith one or more recesses for the reception'of one end of said locking .ba'r, said locking bar being adapted as either 7 one of said sashes is moved to be automatieally thrown into locking engagement with one ot said recesses and the signal bell thereby sounded.
, 2. The combination 'o' f'a pair'of windowsashes, a bracket provided with twosvertical members connected with the upper rail of 'thelower sash, a signal bell providedwith a push button supported from the front memher of said bracket; a locking bar curved upwardly at its front end slidably supported plate being rigidly secured to one of the vertical members of theupper sash, spring actuated means for retaining said locking .bar in yielding. contact with said -vrtical pla'te andi the lower side of said push button,
said bar being adapted as either one of said sashes is moved to'be automatically thrown into locking engagement witli one of. the re 'cesses of said bar, said bar being'adapted as -it is thrown'forward into one of said recesses to actuate the push buttqn of .said
signal-bell, allrsubstantially-- as and for the purposes specified.
In testimony whereof .I aflix my signature in the presence of two witnesses.
