Application-medhotelier-23, 1922. Serial No. 596,216.
To .alt ctr/tom it mcay concern Be .it known that 'rI,--.G.EORGE FRAN LIN NAN ,Mn'rra, a-citizeniof-the lln tedlgt ite and resident of Indianapolis, county of Marion, and State of Indiana, ihavesinvented acertain new and usefuloLQQk forWindow :Sas'h; and 1 .do hereby .declare kthat .rflle bfOllQWiIlg is .a full, clear, and ex ct description thereof, reference-being hadto the accompanying drawings, All which thke numerals;meter to alike pa ts.
. llOGl.. The chief .objeet ,of this invention Ilhiswinvention relatesto ay-window sash window prevents, "to .a considerable degree,
swayingof the window in :thecasing,
The chief feature of *the, invention in .ob-
taining complete 5 security when it is desired torhave windows oftthe guillotinetypeopen either at the .top or at theflbottoln, or .at
both the topand the bottom. vThe Jock when attached :to the windows secures the same together in the adjusted position and is only releasable from .the inside of the avindow by simply ,releasingthe latch.
The full nature.oftIiis'invention will be understood from the accompanying drawings and the following description and claim.
In the drawings Fig. 1 is a sideielevation- :11 view oftthe inside of the window construction to which the invention has been applied. Fig. 2 is an enlarged side elevational view of the cooperating window parts and the sash lock therefor. Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2 and in the direction of the arrows.
In the drawings 10 indicates a window casing providing the slides ll'for receiving the upper and lower Window sashes 12 and 13. In windows of the guillotine type, the upper and lower windows 12 and 13 are slid-ably supported in parallel planes and are adapted to slide by each other. 'As shown in Fig. 3 the lower portion of the upper sash frame and theupper portion of the lower sash frame each is beveled and said beveled portions are adapted to engage each othetiand form a,tight joint when the windows arein closed position} Uponone side portion ofthe upper window sash 1,2-thereis;secured astrap ,l{i,.as by rneansrofthe screws 15. This stra p 14 is provided withz centering recess ltiieh sa plurality .of sockets or recesses 17 which are inline with each, other and whichjherein are shown as textending entirely through the strap, thereby permitting the .Strapito be made by ajpunching process. Th6 length of the str p 14 ibeasdes efd, the same being determined by the. .nun beriof positions in which it ,is-jdesiretl. to lock the win; dows in opened relation.
Associated with the retaining s rap .14. is a 'latch construction and this ,is ,shown most clearly in Figs. 2 an'dB- flnsaifdtiguresithe ,latch construction 'is shown 35130111 prising a rectangular ilmusing portion d8, which rectangular housing portion is .open uponone face and its opposite iface is irevide'd with an aperture '19. Theapertured face likewise is provided withan integral projection '20, which projection extends inwardly into the housingend jformsas pring retainer. The housing suitably supports within the sa1ne, -and oppositelthe aperture 19, a pivot pin 21,;antl said pivot pin '21 .pivotally supports a bell crank .lever 22 having an arm portion 23 whic'lrextends through the aperture 19 and terminates in .a suitable jloop 2dadapted to -reeeive= ac ord :or chain 25 carrying a ring 26. [The other tend of the lever 22 terniinatesin two transverse wing portions 27 and a projecting "locking tooth ,28 having a beveled edge 29. Extending from .the tooth 28 is; a projection '30 which also is beveled, and-extending 11 wardly and oppositely from the beveled tooth 28 is a projection 31 which forms an other spring retainer. Intel-posed between the bevel tooth 28 and the apertured face of the housing 18 and surrounding both projections 20 and 31 is a coil spring 32 which normally presses the bell crank lever outwardly from the housing so that the tooth 28 engages the strap 14 and preferably positions said toothed portion 28 in one of the openings 17. The housing is likewise provided with a flanged base 33 which is suitably apertured to receive securing means 34, herein shown in the form of screws which secures said base, and, therefore, the housing to the upper portion of the lower sash 13 adjacent the strap 14.
From the foregoing it will be noted that the device consists essentially of but the fol lowing; a socket forming, strap, an integral housing, a pivot, a spring and a bell crank latch.
The operation of the device is as follows: WVhen the upper sash is raised from an open position, the wall of the apertured socket 17 engages the beveled edge 29 of the tooth 28 and tilts the pivoted latch in position to the spring 32, and thus the window may be moved upwardly to close the same. a similar manner the lower window sash may be moved downwardly and the pivoted latch will again be tilted as the beveled edge 29 engages the successive slot edges. However, when it is desired to move the upper window sash downwardly or the lower window sash upwardly, the flat edge of the tooth 28 engages the first socket 17 and is seated therein by means of the spring 32 and thus further relative movement of the two windows is prevented unless the lever is tilted by suitable means, such as the chain 25 herein shown, whereupon the window may be moved to the desired position and therein latched.
It will be noted that with the foregoing construction it is possible, see Fig. 1, to position the upper and lower window sashes in such relationship that an opening is provided at the top and bottom of the window frame or casing, thereby insuring circulation and also insuring that further opening movement is impossible, except from within the house or from the inside of the window. Any movement of the lower window upwardly will likewise move the upper window upwardly, and any movement of the upper window downwardly will likewise move the lower window downwardly, so that the relative positions of the windows are thus fixed. Should, however, the upper window be moved downwardly from with out, or the lower window upwardly from without, the construction is such that the window will be locked in the next lowest position etc. Therefore, any tampering with the window will serve to decrease the opening of the window.
The construction is such that the bell crank lever bears upon the strap 14 and thus rattling of the window is either prevented or materially reduced. Furthermore, the recess 16 serves as a guide to center the upper window with respect to the lower window in the relative movement of the two and this serves to position the strap 14: in line with the tooth 28. The position of the tooth 28 in any one of the sockets 17 serves to prevent swaying of the window within a limited range.
Another feature of the invention permits the removal of the usual center sash lock and this provides a clear glass field in the window. Another feature that the latch provides is that the same is self-locking as hereinbefore suggested and thus when the lower window is positioned in its lowermost position and the upper window in its uppermost'position, the latch automatically engages in the lowermost opening 17 and automatically locks the two windows together.
The invention claimed is:
A sash lock including an enclosing housing having but one open face and an opening in the opposite face, a bell crank lever pivotally supported therein by two opposite faces continuous with the before mentioned face, said lever having one end projecting through the opening and the opposite end adapted to extend beyond the housing through the open face thereof and said lever also having an inclined face and an edge for window locking purposes on the opposite end, spring means positionable upon within the housing and interposed between the housing and the lever normally forcing said lever locking end outwardly, and a spring retaining projection extending inwardly in and integral with said locking lever locking end and oppositely extending from the face and edge thereof.
In witness whereof, I have hereunto ailixed my signature.
