, Therefore, the strip shown in Figure 3 conserted in recesses 18 inthe ralls 19 of the Patented Jan. 5, 1932 sraras Parent orriea WILILIAM H. MCH'UGH, 0F ELDORADO, KANSAS, ASSIGNOR 0F ONE-FOURTH T0 CLARENCE IR. FRISBY, OF ELDORALDO, KANSAS SASH LOCK AN D WEATHER STRIP Application filed June 28,

This invention relates to window fastening means and it involves means for guiding the window sash in the frame and for positively locking the window sash in any desired position in the frame, the guiding means being so constructed that it provides a weather-strip.

The novelty of the invention will be described hereinafter, reference being had to the accompanying drawings in which:

Fig. 1 is a perspectiveview of a window frame and a pair of sashes to which my invention is applied.

Fig. 2 is a view partly in perspective and partly in section of a window. frame and a sash to which my invention is applied.

Fig. 3 is a perspective view of part ofthe sash-guide and weather stripv and Fig. 4 is a fragmentary perspective view of the sash.

The upper and lower sashes are both constructed substantially alike so it will be necessaryto describe in detail only one of them.

The window frame 1 consists of the usual sides, top and bottom except that in each sash guide-groove is a combined weather strip and guide formed of. a single sheet of metal to provide side flanges 2 and 3 and an intermediate trough-shaped guide having flanges 1 and 5 at right angles to the flanges 1930.

sashes. The cases have tubular extensions 20 which open at the inner edges of the rails through plates 21. In the tubular portions are bolts or detents 22 having collars 23 against each of which one end of a coil spring bears, the other end of the coil spring bears against theplate 21. Outside the plate 21 is a cam actuating lever 25 pivoted to the bolt or detent 22, the cam face 26 of the lever riding on plate 21 to cause the withdrawal of the end of the lever from the teeth of the pinion gear when the lever is in the dotted line position shown in Figure 2, that is, when the lever is swung down to rest upon the stop 27 carried by plate 21.

When the lever 25 is in the position shown in dotted lines in Figure 2, the pinion will be free to'rotate. Then, the sash can be raised or lowered because the pinion will ride on the rack. Sash weights may be used if necessary but they will not always be required. When the sash is in the proper position, that is, either raised or lowered, the operator can swing the lever to the full line position shown in Figure 2 so that the bolt Will-engage between the teeth of the pinion and lock it against turning. Then, the sash will be held against movement in either direction. In other words, the window lock is thus pro- 2 and 3. Therefore, the guide has a central vided.

2 and 3 by means of which the guide can be fastened in the groove 7 in the flange.

The window sash, for example, the one designated 8, is provided with an edge groove 9 having side flanges 10 and 11 which overlap the flanges & and 5 so thattheyride in grooves 12 and 13 formed by the flanges 4: and 5 and the rabbet strips 14 in the frame.

stitutes an eflicient weather strip. In the vertical portions of the grooves 6 are racks 15. Meshing with the teeth'of the racks 15 are pinion wheels 16 in cases 17 .which are in- From the foregoing it will be apparent that the device is simple in construction and easy to operate, that the metallic grooves for the racks not only retain the racks but that the strips render the sashes weather-proof.

What I claim and desire to secure by Let" ters-Patent is I In combination, a window frame having a 'vertical rack, a sash having a recess therein,

a hollow metal housing in the recess'having a tubular portion extending through one rail of the sash, a plate on the tubular portion secured to the rail of the sash, a pinion in the housin meshing with the rack, a springpressed b0 t in the tubular portion extending through the plate, a cam-lever connected to the extended end of the bolt, the cam portion of which bears against the plate to permit the bolt to be withdrawn out of engagement 5 with the teeth of the pinion, the spring being eflI'ective to urge the bolt into engagement with the inion, and a stop member carried by the p ate below the lever to limit the swinging movement of the lever.
