`*Application filed November 8, 1924. Serial No. 748,665.v

taken on the line 3-3 of Figure 1; and

. Figure 4; is a view similar to ,Figure 3 taken on theline of Figure 1.v

Similar reference numerals in all of the figures of the drawing designate like parts.

Referring to the drawing, it will be seen that the improved window comprisesan upper pane 1 0, and a lower pane 11, fthe upper Apane being preferably xed in position in any suitable manner and having its lower edge supported upon a filling strip 12, in-

serted in a recess 13 formed 1n the sides of the window frame 14, whichy is preferably -constructed of concrete and precast prior to v its mounting within the walls of the buildmg. l

The lower pane 11 is mounted vto slide freely up and downto various positions, andits vertical edges engage the free ends of spring-guide members secured in position within the recesses ,13 at both sides of the window and extending approximately the full length'of the window and preferabl constructed of spring-brass material. Eac 40 of the spring-guide members is constructed of sheet-metal and is bent to form legs 16 and 17 arranged at right-angles with re'- of the frame by suitable fastening means 19,

and its free end 'is bent backwardly and spaced from the main portion of the/'leg to form a spring-tongue 20 adapted to frictionally engage the adjacent vertical edge of l the lower pane.

Figure 3 1s a transverse sectional view y Pane 11 is also frictionally held in place against the spring-guides 18 byl suitable pads 21, (preferably formed of felt), secured to the rear faces of the window-frame stops 22, each stop preferably having its rear face formed with a portion 23 adapted tolie'approximately parallel to the panes and a remaining portion 24 inclined from said parallel ortion 23 to provide a widened space forming part of the reces:J -13 and into whichy is adapted to extend the leg 17 of the spring guide. The felt pads21 have one end secured to said parallel portions of the stops 22, and are bent backwardly over said secured ends on the parallel portions, and then each has its other end secured to the said inclined portion of the stop.

Stops 22 are preferably formed of concrete and precast before assembly, as is the frames or 'ambs heretofore described.

- n the sill of the window, also preferably 1,695,903V APATENT OFFICE;

formed of concrete, is formed a groove 25 irri," f

which is located a sill-pad 26 of felt, against.

and upon which the lower edge of the lower pane 11 contacts and rests when said lower pane 1s down or 1n 1ts closed pos1t1on, and

at the top of the window is arranged a pad 27 lfixedto a horizontal stop member 28 and ladapted to extend across the path of the lower pane and engage the front faceofthe upper pane adjacent to its upper ed e.

It is understood that themvertical remova le stops 22 and the horizontal stop 28 can be cast together as a unit, or separately, as

desired.

Lower pane 11 is preferably provided with a knob or knobs 2 9 adjacent to its lower edge with which the .pane can be vraised or lowered as desired, These knobs ca n be secured to the glass in any suitable manner, preferably by cement. y E i I' To assemblel the arts of the window, the upper pane is first xed in position upon the filler strips 12, then .the spring-guides are placed and fixed in-position with their guidlng legs 16 bearin at against the surface.

dow-sill, all danger of breakage by contraction or jarring is eliminated.

3 These windows-are'especially adapted for use in fire-proof constructions having precast jambs and window-stops, and more especially Iin all windows of standard narrow designs where an overweight of the glass will not be an objection.

ltheupper pane is shown of less length than the lower pane, and the' upward movement of the lower .pane is limited bythe upper ad 27, but it is understood, that if desired, t e upper edge of .the lower pane caribe made to slide into a pocket at the top side of the window.

If necessary, especially where a heavy sliding paneis used, window locks can be used at the sides thereof to hold the same in adjusted positions.

The special formation shown of the spring-guides is essential, in that` the springpane vstationary at any raised position desired,

tongue is unhampered, and its .angular shape and folded front edge make the remaining part substantially rigid.

Having fully described the invention, what is claimed, is:

. 1. In a window construction for concrete structures, an upper sashless pane fixed in position against movement, a lower sashless pane which extends into recesses at the sides of the window frame, a guide at each side ofthe window extending continuously the full height thereof and provided with a leg adapted to engageone face of the upper pane and press it against an abutment of the precast frame and said leg being also provided with a spring-tongue adapted to en-v I gage the full length-of the adjacent vertical `edge of the lower pane at all times, and" precast side stops having Iiexible pads for engaging the face of the lower pane adjacent its vertical edges to ret-ain lthe same in position.

2. In a window construction for concrete structures, an upper sashless pane fixed in position against movement, a lower sashless pane which yextends into recesses at the sides of the window frame, a guide at each side of Athe window extending continuously the full height thereof -and provided with a leg v adapted to engage one face of the upper pane vand press it'against an abutment of the pre- A cast frame and having a turned-back free edge to form a rigid spacing-guide for the lower frame, vided with 'a spring-tongue 'adapted toengage the full length of the adjacent vertical edge of the lower pane at all times, 'and ,precast side stops yheaving. iiexible pads for engaging-the face of the lower its vertlcal edges'v to retain t position.
