WINDOW AND CASEMENT.

Toall' whom it may concern Be it known that I,

V CRITTALL, a subject of the King of Great up and down in metal jambs. The body of the jamb consists of a flat metal plate which is preferably the head of a T the stem of which is let into the wall. Along the outer edge of the plate there is a flange pro]ect1ng at right angles from it. This flange may be conveniently formed'of an angle iron riveted to the plate. A strip of bronze or the like is preferably fixed to the inner faceof the flange. Near the middle of the plate is fixed a grooved bar, on the inner side of which is preferably fixed a strip of bronze or the like. A second grooved bar is fixed at the inner edge of the plate. Each sliding frame consists of a double flanged or trough shaped bar and the outer faces of the outer flanges of these bars preferably have fixed to them strips of bronze or the like. The strip on the outer flange of the upper frame slides in contact withthe strip on the inner face of the flange of the jamb plate, while the inner flange of the upper frame runs in the groove of the central grooved bar. The strip on the outer flange of the lower frame slides in contact with the strip on the inner side of the central grooved bar, while the inner flange of the lower frame runs in the groove of the inner grooved bar. Each frame is provided with rollers (preferably four) which are pivoted between their flanges and bear againstthe outer faces of the two grooved bars.

The invention is applicable to the casements described in the specification N 0. 1,002,228 the outer frames of such casements being made to slide up and down in the jambs as above described. The draw ings show such an'arrangement.

Figure 1 is an outside front elevation and Fig. 2 is a vertical section on the line 2- 2, Fig. 1; Fig. 3 is two local horizontal sections, the front part being on theline 3-3,
