5 ing of the window, either from within or from without; control over the extent to which the window may be opened; security of the window mechanism against tampering; and general good appearance. Windows constructed in accordance with the invention are specially suitable or adaptable to serve as detention windows, in hospitals and other institutions where criminal or mentally deranged persons may be confined.`

In the drawings, Fig. I is an elevation, from the inside, of a window conveniently embodying our invention, with theV left hand iainb and associated parts in vertical section in the plane oi the lower sash.

Fig. II is a fragmentary vertical section, taken as indicated by the line and arrows II-II in Fig. I.

Fig. III shows a horizontal section through the window :lamb and associated parts, taken indicated by the line and arrows III-III in Fig. I, on a larger scale.

Fig. IV shows a horizontal section through the counterbalance housing, taken as indicated by the line and arrows IIT- IV in Fig. I, on a larger scale.

Fig. V is a fragmentary edge View of the jamb and the counterbalance housing from the left of Fig. I, on a larger scale.

Fig. VI is a fragmentary vertical section through the counterbalance casing, taken as indicated by the line and arrows VI-VI in Fig. IV.

Fig. VII is a tilted or perspective View of a sash cable cover.

Fig. VIII is a fragmentary vertical section through the window sas'nes and their meeting rails at the sash lock, which also appears in section, and,

Fig. IX is a tilted or perspective view cfa part of the sash lock. v

As shown in Figs. I and II, the window cornprises lower and upper sashes lo, 11, arranged to slide vertically in a window frame consisting ci vertical jambs 12, 12, a sill 13, and a head 14. In Fig. III, eacn of the jai/nbs l2, 12 is shown as of a general I-section, including flanges l5, 15 that form the inner and outer stops or guides for the sashes 10, 11 and engage in the masonry of the wall, and also a thickened central portion to which is secured an I-shaped parting strip 16, associated with resilient weathering 17, and cooperating with the flanges 15, l5 to form the sash ways of the jainb.

The sill i3 is shown as of a channel section, and the head lli is cornposed oi an inner channel .section and cuter I-section, with their flanges riveted or otherfise suitably secured tege" er. The rails that orin the sashes lo, il are of a channel section. As shown in II and VIII, the meeting rails 18, 19 oi the sashes 1G, l1 have sloping flanges 18a, 19a that o erlap vertically and make Contact with one another to forni a tight joint. t The counterbaiances 20, 2o for the saslies 10, 11 are located behind the jainbs 2, l2 and, as here shown, are of a coil spring type. These counterbalances 20, 2G are arranged side by side and are enclosed in common casing or housing 21 having feet 522, 22 which. are secured to the outer face of the jainb 12 by suitable astcnings, such as rivets 23. The counterbalances 2D, 20 are'connected to the sashes 10, 11 by flexiblenietal tape connections 25 extendle ing out through the lamb Wall to the sashes 10, 11. As shown in Fig. l, the lower ends oi these tape connections 24, 25 are attached to hooks 2o secured inside the channeled bottom rails 28, i9 of the sashes lo, 1l projectinO- into vthe chan- 5 neled side rails 29. counterbalance 2O may be ci any suitable or preferred type, here shown as comprising a o` 3i) mounted to rotate in a frame formed by spaced plates 3l interconnected by angular corner members which are secured to a base plate Sby suitable fasten-ings, such as bolts Sil. The tapes 24, 25 enter housing 2l through slots in the janib wall and have their ends hooked 'through openings in the drum 30, as shown at 36. A spiral counterbalance spring 37 within the drum 30 has one end hooked on the drum wall as indicated at 38 and the other end hooked into a stationary central hub 39 mounted in the plates 3l.

As shown in Figs. I, IV, V and VI, the jainb wall directly in front of the counterbalances 2i), 20 is formed by the counter-balance base plates 33, 33, which lie in and fill corresponding openings in the webs of the jarnb l2. 'Fliese plates 33, 33 are secured to the lugs or feet of the coun-- terbalance housing 21 by suitable fastenings, such as screws 41, so that the counterbalances 2U, 20 can be conveniently attached and removed. The housing 21 not only encloses and supports the counterbalances 20, 20, and protects them from dirt, plaster, grout, etc., but also interconnects the portions of the lamb 12 above and below the area of weakness where the janib web is cut away to receive the plates 33, 33, in which are` the tape openings 35, and reinforces this portion
