vI am able to attainthese -anaotner V oloioots of the Ainv n1ii-on .by LProviding -fmovabie :bolt moana such as a spring-actuated rotatable plate., gn vone check rail -of a window. for.V engagement lwith a holdinefmeans Suohas afoatoh haring-an overhanging lip,fon the .other check rail of thawindow.f I then. provide Vmeans Afor.automatically noldinsthemovable.boltin looked position .when the .Window Vis closed; land thiscan Well .be the Spring-of the sprinseaotnatednpiate, and .means foi-:automatically ,holding the bolt in open vvvpesition while. the window lis fleeingi opened. This elast. meanscan be a spring-.actuated stop which moves into,.place when ,the rotatableEplateismoved into; an y unlocked position, .and which K is knocked out of ,engagement Withthe plate once the platefhas moved pastthe lipin theoateh. Then, to cornplete fthe fastener,. there .is :provided means for automatically locking the Window when .it is closed. This can bean inclined plane .forming the top of theoatch.and against which the rotatable plate slides until it finally moves into locking position,
A Window fastener of thertype disclosed herein-has many advantages overthe old type fastener that is moved entirely by hand. It also has many advantagespover thefolidnary .spring-operated fastener. With this fastener the Window is lockedbymerely closing it, andit is locked v.so tightlythat'it cannot be openedfrom the-outside withoutbreaking the glass. The fastener also-has theY advantage that when thefmovable portion is shoved by hand to an unlocked position it is automatically held --in this position so that the window may Ybe.raised with both-,hands operatingonjt at-A the gsame time.l
The invention Will be described in detail as applied to the embodiment illustrated in the ac- 6. Claims. Cl. 22927336) 2. compari-ring drawings. of the drawings, Fisinfe 1 is aplan yiew ofthe Window fastener ina locked position; FgureZ is a front elevational View similar to Vliligure 1; Figure 3 is a View taken along theline 3T3 of Figure 1; Figure 4 is a plan View of the ,fastener in Aopen position; Figure 5 is a front elevational view similar to .Figure 4; Figure `6 is an elevation showing the position of the fastener members While the bottom sash of the window is being raised; Figure 7 is an elevation, partially broken away, showing the position of the fastener members When the bottom sash has been raised a still greater distance; and Figure 8 is a viertv `rtaken alongv fthe line 8--8 of Figure 4.
theembodiment shown the fastener comprises a base mounting l0 for the rotatable .plate or bolt Il and fastened to the top of the check rail l2 ofthe lower sash by means of two screws. Positioned just opposite on the top ,of the check rail l`3'of the upper sash isthe .mounting I4 for the catch I5. into which the rotatable plater II turns to lock-.the Window. The rotatable plate is rotatablylmountedon its base by means of a rivetorfbrad |56; yso that it is free to turn through at leasta 90 anale when ,it isin position to engagetheoverhanging lip I1 in the catoh I5; The rotatable plate I.I is provided with a rounded handled I8 for turning the plate vand Vwith an inclined surface I9l sothat, when it is in locking position, it will Wedge against the lip IK-'l of the catch and hold the tvvo check rails tightly together.
I n :order `to move `the rotatable plate automatically into locking position there is provided a strong springg ofthe hair-pin type, preferably looated .within the pbase mounting lo' of the rotatable `plate vIL-I. Thisspring is arranged so that it is under great tension when the rotatable plateisin completely open position.
The catch 1-5 which the rotatable plate LI en;-
saeeeornnrises a rounded nortionl risinsto a.
peak .and having anovernaneine 1in Wunder Whioh thelrotatableplate lookswhen the fastener isin looked position- Tlie rounded portion 2i fornisaninolneol :rounded .Snrfaoe-22 over which therotatabieplate-slides when the, window is being raieedandiowered.
Inprderto hold the rotatableplate I I in open position when the Window. is to` be raised there is provided .a Sprine-operatedstop. ze (Figures) mountedjn the basel ofthe catch [-5. This stop has a retaining surface 24;Whichauto.-
matically engages the rotatable platel I and holds it open.
`The operation of l the self-locking fastener is as; follows: ,Withl the. fastener in lockedfposition as shown in Figuresl var1d 2 thehandlel of; the rotatable plate ll isgrasped .by thehand and turned in a counter-clockwise direction. When the plate has reached full open position the stop 23 and onto the inclined surface 22 of the .Y
peaked catch I5. Then the raising of the window is continued to the desired position.
On lowering the window the rotatable plate II again engages the inclined surface 22 of the peaked catch and, operating against this inclined surface, is forced around in a counter-clockwise o direction, thereby applying tension to the plates spring 20. When the rotatable plate I I nears the bottom of the inclined face 22, and has reached the bottom of the overhanging lip I'I, the bottom of the plate strikes the top of the retaining surface 24 of the stop 23 which projects out beyond the inclined face 22. Then on lowering the window the last fraction of an inch the stop 23 is pushed down out of the way by the plate and the spring 2B forces the plate around, in a clock- Wise direction, under the overhanging lip II; thereby automatically locking the window.
Having described my invention in considerable detail as related to one embodiment of the same it is my intention that the invention be not limited to these details but rather be construed broadly within its spirit and scope as set out in the accompanying claims.
I claim:
