VENTILATING-SASH LOOK.

Application filed September 22, 1921. Serial No. 502,396.

To all whom it may concern Be it known that I, ELI F. BRIGKELL, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented'aVentilating-Sash Lock, of which the following is a full and complete specification.

The primary object of y invention is to provide a simple, neat and inexpensive sash- 1 0 lock comprising fixtures which may be readily and conveniently attached to theupper and lower sliding sashes of a window for securely locking them when the window is closed, and adapted also for operation to safely lock said sashes when either-one is slightly moved t'o open'the window for the purpose of ventilation. r

This principal object of my invention is accomplished in the present instance by means of a fixture or pivoted locking-bar attached to a side rail. of the upper sash and having a limited swinging movement from an approximately vertical position to a horizonta-l position, in combination with a fixthe outer end of the swinging locking-bar in its depending position to lock the sashes ture or engaging plate on the upper part of the lower sash; whereby when the window is closed the sashes will be securely locked in this position by engagement of the fixture on the lower sash with the outerend of the depending locking-bar carried by the upper sash, and when it is desired to partly open the window for the purpose of ventilzitionby either slightly raising the lower sash or lowering the upper; sashthe' locking-bar may he swung outward to firmly and safely lock said sashes against furtlier'movement by engagement of the fixture on the lower sash with the inner or pivoted end of said locking-bar.

particular construction and arrangement of the fixtures comprising the device for look ing the sashes of a window in both. a closed and slightly open position; all as hereinafter fully described and specifically set forth in the claims.

In the accompanying drawings, forming a part hereof Fig. 1 is a front elevation illustrating the application of my invention.

Fig. 2 is an enlarged front elevation of the sash-lock applied with the parts or fixtures in normal position and the sashes in closed position. i

Fig. 3 is a vertical sevtional View through position.

My invention consists, therefore, in the the window sashes to show the sash lock in side elevation.

Fig. 4: is a detail view of the plate for supporting the locking-bar and limiting its swingi g movement. i

Fig. 5 is a view of the locking-bar detached from its supporting plate.

Fig. 6 is a vertical sectional viewithrough the locking-bar and its attaching-plate, with the locking-bar disposed in its horizontal As illustrated in the drawings my invention is applied to that conventional type of window in which are employed upper and lower sashes 10 and 11 slidable in a frame in the usual manner, and the device which I employ for locking the sashes closed or slightly open comprises a fixture or swinging locking-bar 12 pivoted at its upper end in an attaching-plate 13 fastened to a side rail 10' of the upper sash 10 and a fixture or bent plate 14 secured on the upper rail 11 of the lower sash in alinement with the aforesaid swinging-bar, so that said plate may engage against movement when the window is closed (see full lines, Fig. 3) and may also engage the inner portion or pivot end of said swing- -ing locking-bar when the latter is swung outward and the sashes moved to open the window (see dotted lines, Fig. 3); it being understood that the attaching-plate which carries the locking-bar is provided with means, hereinafter particularly described, for limiting the upward swinging movement of said locking-bar so that it,may form a stop against any further movement of the sashes with respect toeach other.

-In the present: instance the attachingsplate is provided with holes to receive the screws 15 and at its'lew erend with spaced apart cars 16, '16, forming the bearings for the swinging lockiiig-bar 12, with a transverse shoulder 1'7 between the upper part of the ears so as to limit the upward swinging movement of said bar. as indicated in Fig. 6. and I prefer to make the locking-bar or stop device, carried by this plate of a metal bar bent upon itself with the terminals 105 turned abruptly outward to form pivots or gudgeons 12 12", by which. said locking-bar is pivoted in the cars 16 of the plate. :lhe looped end of the rod forming the lockingbar is the outer end when said bar is pivoted no in the mine, "and as the rod is of spring metzil'the free endsthereof on *whichthe gudgeons are formed may be brought together in pivotally;connecting-the lockingbar to the ears on the attaching-plate.

The fixture which is adapted to' cooperate with. the locking-her consists of a plate 14 having holes for theattaching screwswind an upturned inner end 1 1 forming a stop to limit the inward movement-(d fine depending locking-bar when the 1 sashe are "closed and I lso "a -n engaging portion "which bears against the inner p'oi'tion 0t sz'ti'd' locking-bar, near its pivot,*Whiflthedmr is swung oi'itufzi 'd find thelo wer sesh moved to the pertly open Jpo'sitio'n shown in *dotted dines -Fig. "3. v p In "itta'ehing Y the two ifi'xtii'res constit'uti-ng "I'ny ventileti ng s'ash lo'ck the bent plate 14iis first applied by seeuri'n'g the seine on the ineeting' reil 11 of the lower sash 11 immediately in"fro'nt' of one of the side rails 10 ofthe upper sash 10, sothet "th e'i'ipturned inner end 14 of t'hep'lete -will 'be etthe inneredge of t-he arforeseid "'r'ztil 11.

"the sashes. Of course the length of the locking-bar, or distance between the plates 13 and 1 1, determines the. extent to .which the window maybe opened, and asit is the purpose of the device to prevent the Window from 1 being opened suificiently to allow e person toenter *throughthe same the length of the swinging bar should be such as to permit the window to be openedonly slightly, HIS for instanceto the extent indicated in the drawings. The "lock therefore provides a sefen'i'eens by which the window may be partly! opened to ventilate a room, and the f -look in'g ber drops by gravity when the window is closed 1 the operation of 1 locking the sashes w in closed position iseutOmetic, as will i be understood When it is desired to' fully' open the window it is necessary only to first detach the locking-bar by disengaiging it from the spivot-ears of the ettach ingplate 13, thus *remov-ing -the stop device {and permitting theiplzttes to'pass each-other. It will be noted, however, that when thelocking-bar is in place it becolnesztpos-itivestop-device to --efi"ectually prevent -1noveni'ent ofthe "sashes-beyond a limited extent, and therefore provides a safe Ventilating sash-lock.
