MARSENA G; FrNcH, or FRANKLINVILLE, NEW YORK.

SASI-I-LOCK. v

To @ZZ whom t may concern."

Be it known that I, MARSENA Gr. FINCH, a citizen of the UnitedStates, residing at Franklinville, in the county of Cattaraugus and State of New York, have invented cer! tain-newV and useful Improvements in Sash- Locks, of which the 4following is a specification, reference being ing drawings. i

VThis invention relates to an improved sash lock and has forA its primary'object to provide asimple and eective device for securely locking 'the upper and lower window sashes together', and means for holding the movablelocling element in an inoperative positionso that the sashes may be moved relative to'each other. i

It is another and more particular object of the invention to provide Va simple and effective means for holding `the springpressed element of the. sash lock in its inoperative position, said means including a leaf spring fixed at oneend to the locking element and movable therewith, said spring having its other end offset for engagement over the edge of the base plate of the lock and adapted to be disposed in the path of the lower horizontal bar of the upper sash frame so that the spring will be disengaged from the base plate when the upper sash is moved to its closed position and thereby release the locking element.

It is a further object of the invention to provide a very durableandserviceable sash lock which may be readily applied to the ordinary window without necessitating any alterations therein.

With the above and other objects in View, my'invention consists in the novel features of construction, combination and arrange ment of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawing, in which,

Figure 1 is a fragmentary elevation showing my improved locking device applied to the window sashes; Fig. 2 is a top plan view, the locking element being in its normal position; Fig. 3 is a similar view showing the locking element latched in its inoperative position the upper sash being lowered; and Fig. l is a section taken on the line Jr-1 of Fim 8.

leferring in detail to the drawing, 5

had to the accompanydesignates a base plate which is secured by means of the screws, indicated at 6, to the horizontal top rail of the lower window sash Specification of Letters Patent.

7. A pin or stud 8 is centrally fixed in this base plate, and upon the same the locking lever 9 is loosely engaged at a pointA intermediate of its ends. The upper end of the stud or pin 8 is formed with a head 10.

Upon the base plate 5, adjacent one edge thereof, a lug 11 is xec, said lug having a laterally projecting lip 12 the lower edge of which 4is spaced from the base plate.V One end of a length of resilient wire, indicated at 13, is iixed to the lug 11, and the medial portion of said wire is formed with a plurality of coilsll engaged upon the pin or stud 8. The other end of the wire 13 is securely fixed tothe pin 15 mounted in the locking lever 9, as clearly shown in Fig. 2. One end of said locking lever is formed with a hook bill 16, and upon the other end of said leverV one end of'a leaf'spring `17 is securedupon the pin 18. rThe upper end of this pin is formed into a suitable nger plate 19. rlhe free end of the leaf spring 17 is angularly offset, as shown at 20, for a purpose to be presently explained.

Upon the lower horizontal rail of the upper sash 21, a `plate 22 is fixed, and upon said plate a curved keeper rod 23 is secured at one of its ends. The spring coils 14 normally act to hold the locking lever in the position shown in Fig. 2 of the drawing, wherein the hook bill 16 is engaged with this keeper rod, thereby holding the upper sash against downward movement and preventing upward movement of the lower sash. It will be noted that the opposite end-of the locking .lever is disposed beneath the lip 12 on the lug 11, whereby excessive strain upon the hook bill and possible bending thereof in the attempt to move the sashesv relative to each other, is obviated. rlhe inner edge of the hook bill on the lever 9 bearing against the rod 23, draws the meeting rails of the two sashes together and thus produces a tight joint or connection.

When it is desired to adjust the sashes, the operator simply forces the inner end of the lever 9 to the position shown in Fig. 3, wherein the same is disposed substantially in parallel relation to the rail of the lower sash. The upper sash may then be drawn downwardly and the free offset end of the spring 17 will immediately engage over the outer edge of the base plate 5 and hold the locking plate against return movement to its normal position under the action of the spring 14. The window sashes may now be Patented Dec. 19, 1916. Application mea May 1, 191e. serial-N0. 94,737.

moved to any desired positions with respect to each other. When the sashes are again closed, in the upward/'movement-oftheupper sash to its closed position the plate 22 will strike against the free end of the leaf spring 17 and force the same upwardly abfOYethe plate 5 on the lower sash so that the spring 14 may immediatley act touthrowtheflocking lever to its normal position and engage the bill 16 tliereoiiwith the curvedhkeeperrod 23, thereby .a gainf lockingA the sashestogether and holding the same. securely closed.
