This invention aims to provide-simple means whereby an upper window sash may be locked to a lower window sash, in adjusted positions, so as to leave a'ventilating open- 1'. ing of greater or less size above the upper edge of the upper window.

The device comprises a bolt and a keeper plate wherewith the bolt engages. The invention proposes improvements in the mounting of the bolt and improvements in the keeper plate, the construction being such that the operator does not have to bore a hole for the reception of the end of the bolt unless he wishes to do so.

It is within the province of the disclosure to improve generally, and to enhance the utility of, devices of that sort to which the invention appertains.

which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of.

bolt in a plane close to the face plate that is attached to the bolt casing;

, Figure 8 is a longitudinal section showing how the bolt works when no hole is bored in the upper sash for the reception of the end of the bolt;

Figure 4 is a cross section on the line 44 of Figure 3;

Figure 5 is a cross section on the line 55 of Figure 3;

Figure 6 is a perspective view showing one end of the bolt casing.

Figure 7 is a longitudinal section showing how the device looks when a hole is bored in the upper sash to take the inner end of the bolt.

The numeral 1 marks a window frame in which an upper sash 2 and a lower sash 3 are mounted to slide. A keeper plate 4 is attached by securing elements 5 to' one stile of the sash 2. The plate 4 has outstanding, longitudinal reinforcing ribs (3. The plate 4 is provided with openings 9, the plate being struck outwardly, as at 7, above the openings, to form shoulders 8, and to form shoulders 28 which slope downwardly and outwardly above the shoulders 8. The reinforcing ribs 6 are located on opposite sides ofthe shoulders 8.

i A tubular casing 10 is mountedin'the lower sash 3 andhas an opening at its inner end, as Figure 8 will show. At its outer end, the casing 10 has laterally extendedflanges 11 I which, when the casing 10'is in place, may With the above and other ob gects in view,

becountersunk into the lower sash 3, as shown'in Figure 7. A face plate 12 abuts against the flanges 11 of the casing 10. The casing 10 is provided'at its outer end withfingers 14 located opposite to each other, and 90. remote from the flanges 11. The fingers 14 are received in notches 15 in the edges of the face plate 12, and are heldthereing elements 16 hold the face plate 12 againstv the outer surface of the lower sash 3.

A bolt 17 slides in an opening 21 in the face plate 12, theopening 21 having oppositely-disposed lateral extensions 22, shown best site-disposed outer shoulders 24, the shoul ders 23 and 24 being in alignment, lengthwise of the bolt17,as Figure 7 shows. The shoulders 23 are of such" size that they can go through the extensions 22 of the hole 21 in which the bolt 17 slides. There is a head 25 on the outer end of the bolt 17 and the in by being welded or riveted down. Securbolt has longitudinal grooves 26 that extend within the head.

The bolt 17 may engage the shoulder 8, as shown in Figure 3, and when the bolt is rotated on its axis, the shoulders 23 and 24: are disposed on opposite sides of the face plate 12, thereby to lock the bolt against movement either inwardly 0r outwardly.

If there is a recess 27 in the upper sash 2, the operator can slide the bolt 17 lengthwise, so that the outer shoulders 2st are with in the tubular casing 10, and then, by rotating the bolt so that the outer shoulders 2a are not lined up with the extensions 22 of the opening 21, the bolt will be held advanced, in the position of Figure 7.

By PIOVltllllg both the shoulders 23 and the shoulders 24, the operator may use the seat 2-7, as in Figure 7, or dispense with it, as in Figure 7, some persons objecting to boring into the sash to form the seat 27.

When it is desired to hold the bolt retracted, the bolt can be rotated until the inner shoulders 23 are lined up with the extensions 22 of the opening 21, the bolt being moved outwardly through the extensions 22. Then, if the bolt be rotated through a small arc, the inner shoulders 23 will engage the outer surface of the face plate 12, and hold the bolt retracted.

Having thus described the invention, what is claimed is:

In a sash-holding device of the class described, a tubular casing open at its inner end, a face plate having an opening provided with reduced lateral extensions, a bolt slidable in the opening and of sufficient length to project beyond the inner end of the casing, the bolt being supplied with inner and outer shoulders spaced apart longitudinally of the bolt by a distance approximating the thickness of the face plate, the shoulders being so shaped as to pass through the lateral extensions of the opening when the bolt is moved longitudinally, spring means in the casing for advancing the bolt, the bolt being rotatable to engage the inner and outer shoulders with opposite sides of the plate, thereby to hold the bolt partially advanced, the bolt being rotatable to engage the outer edges of the outer shoulders with the inner surface of the plate when the bolt is fully advanced, thereby to hold the bolt in such position, the bolt being rotatable to engage the inner edges of the inner shoulders with the outer surface of the plate to hold the bolt completely retracted, and means for securing the face plate in place with respect to the casing.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

SYLVESTER ELMO SONGEY.
