SASH FASTENER.

Application filed May 24,

sition and thus provide greater security against the opening of sash by thieves and burglars.

In the drawings of one embodiment of my invention described and illustrated herein,

Fig. 1 is a plan, partly broken out for convenienee, showing the bolt in unlocking position;

Fig. 2, a similar view with the bolt in locking position; I

Fig. 3, a similar view on a smaller scale showing the fastener on a sash and in unlocking position;

Fig. 5, a cross-section detail on the line 55, Fig. 1;

Fig. 6, a plan of the fastener in adjustable looking or ventilating position; and

Fig. 7, a. partial elevation of two window F sash, partly open and locked withmy novel fastener.

' Referring first to Figs. 1, 2, my novel'tastoner comprises a base plate 1 of suitable size and material, as metal, provided with apertures 2, for receiving screws to secure the plate to the top of the lower sash 22. Fig. 3.

The inner end of the plate, Figs. 1, 2, which overlaps the inner edge of the sash has an eye 3 while the opposite and outer end carries a housing 4; fashioned to provide two.

curved tongues or fingers 5, 6, bent upwardly and inwardly from the edge of the plate and constituting bolt and handle stops hereinafter reterred to, for the handle and bolt.

A bolt operating handle 7, Figs. 1 to. 4;, herein in the shape of an elongated bail or loop, has one end curved downwardly and laterally, engaging the eye 8, and its opposite end provided with a bolt, or, as in this case, by being bent outwardly under the housing 1, to form the bolt 8.

The plate 1 is provide centrally with two laterally extended, upstanding and spaced ribs 9, 10, which act as a detent and a withdrawn bolt stops respectively for the handle 7 at opposite sides thereof. The handle 7. Fig. 1, is provided at a point near the bend forming the bolt with a flattened or grooved 1927. Serial No. 193,792.

section 11 which enables the bolt end of the member 7 to be slid longitudinally, Figs. 1, 2, beneath the fingers or stops 5, 6, in assembling.

The parts being assembled as in Figs. 1 to 4, the plate is secured to thetop of the lower sashnear the edge thereof with the handle lying down upon the sash and the free side of the handle member between stops 9, 10, Fig. 1. A plurality of holes 12 are drilled in the front face of the side stile13 of the upper sash 1 1,

Fig. 3, sufficiently deep to receive the bolt 8 when in described and locking position. Preferably a short piece of metal tubing large enough to receive the bolt 8 is then driven into each hole 12 to prevent the hole from being.

enlarged bythe action of the bolt in entering and withdrawing from the hole,

WVhen the sash are both closed, Fig. 4, and it is desired to lock them, the handle 7 is raised upright until its resiliency frees it from. the

rib or Withdrawn bolt stop 10, then is lowered until it is substantially parallel with the top of the lower sash 22 when it spreads, owing to its resiliency, and the bolt 8 slides outwardly beneath the fingers or stops 5, 6, and into the aperture 12, when the handle is again raised to position, Fig 2, and left to rest behind the ear 15 on handle stop (3. I

In this position it will be clear that the sash are both locked against upward or downward movement, and no knife blade or the like slid up between the twosash could be used to throw the bolt 8 laterally to unlock it, nor could the bolt be worked backwardly and withdrawn from the aperture 12 because of the withdrawnbolt stop .5.

If it is desired to leave the fastener so that either sash or both can be opened part way for ventilation only or in flCljUSll-ftblfi locked position, then after the bolt 8 has slid into the hole 12 the handle 7 is not raised as described, but is left lying on top oi the lower sash, in adjustable locking and ventilating position, Fig. 6.

Now it either sash or both are moved part way, the movement of one sash relative to the other will cause the bolt 8 to turn in its housing and against the corner of the slit 23 of the plate 1 as a fulcrum and the handle 7 to equal to the length of the handle, see Fig. 7,'

- shown in Fig. 6.

Neither sash, however, can be moved a greater distance than the length of the handle permits, the handle being made of desired length with this feature in mind. This feature permits a sash to be raised or lowered a limited distance as desired at night, for instance, or at any time for ventilation, with the assurance, however, that it cannot be moved any further and thus the security of the lock in an adjusted position is also obtained.

This lock is of great convenience on any sash, but particularly for use on sash in bungalows where the sleeping rooms are on the ground floor and where a partlyopened window leaves an especially favorable opportunity for annoyance.

This invention isn'ot limited tothe precise embodiment thereof described and illustrated." r
