WlNDOW.

SPECIFICATION forming part of Letters Patent No. 691,182, dated January 14, 12902. Application led March 5! 1901. .Serial No. 49,869. (No modehl To @ZZ whom it may concern.-

Be it known that I, EDWARD A. SANDERS, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a window; and the improvement relates to certain novel constructions and combinations of devices whereby the objects of my inven tion are accomplished. These objects are, iir'st, to provide a window with simple means by which either the upper or lower sash may be tilted away from the frame for purposes of Ventilating or cleaning and also to provide means by which the window-sash is counterbalanced by a single pair of counterweights and their cords, both when sliding vertically and when tilted outwardly; secondly, to so arrange the windowsash that the upper and lower sash can be tilted away from the frame simultaneously, and, thirdly, to provide a weatherproof construction for the window stops and sash.

My improved window is illustrated in the accompanying drawings, throughout the several views of which similar numerals of reference designate corresponding parts.

Figure 1 is a perspective view showing the lower sash tilted away from the frame. Fig. 2 is a vertical section through the center of the window on aplane at right angles to the plane of the glass. Fig. 3 is a horizontal section through the lower sash at right angles to the plane of the glass. Fig. 4 is a sectional detail of an upper and lower bar of the window-sash. Fig. 5 is a detail of the counterbalancing devices.

As is clearly shown in the drawings, the window consists in a frame l, which may be of the ordinary form; but in fireproof structures I prefer to construct the frame of sheet metal instead of wood. The upper windowsash 2 and the lower window-sash 3 slide up and down in the frame l, being counterbah an ced by the counterweights 4 and theirsash cords or chains 5. In order to permit either sash, such as the lower one 3, to tilt away from the frame, as shown in Fig. 1, for purposes of ventilation or cleaning and to be counterbalanced by its weights 4 not only when tilted, but also when being moved up or down vertically, I provide a pair of auxiliary strips or slides 6, one on each side of the window-sash, which slide vertically with the sash 3, between the outerstop l and the inner stop l1. Near the lower end of each slide is secured an inwardlyprojecting pin 6, which engages a slit 3l in the lower end of each side of the sash 3. The sash 3 is thus supported by the pins 61 and can be tilted outwardly upon them as pivots. A pulley 6" is secured to each slide 6, preferably at a height above the pivot 6IL equal to approximately half the height of the sash. The counterweight-cord 5 extends down past the groove of the pulley 6l when the sash is closed, and is attached at its lower end io a pin or other suitable fastening 3", attached to the side of the sash. When the sash is tilted out from the frame, as shown in Fig. l, the cord 5, which engages the pulley 6b, by being drawn out raises the weight 4:, counterbalancing the tilted frame 3. When the sash is in its closed or vertical position, its lower end rests in contact with the pins 6, and it may be slid up and down between the stops lL and lb like an ordinary window-sash, but carrying with it the pair of vertically-movable slides 6. The sash 3 can be entirely removed from the frame by tilting it away from the frame and raising it so that the slots 3 clear the pins (3, as shown in Fig. 5.

By the device above described I have produced a window having a sash that is counterbalanced by the same pair of weights both during its vertical movement and also when it is tilted. The sash-cord is at all times taut and cannot become entangled with the frame or sash. The vertically-movable slides 6 are concealed from view when the window is closed. l

In order to retain theslides 6 between the stops 1L and lb and to prevent their getting out of line when the sash is tilted, I provide a flange 1C along the inner edge of the stop lb, substantially as shown in Fig. 3. Sufficient clearance is left between the face of the slide and the face oF the flange lc to admit the flange 3c, carried by the sash 3. The fiange 3c fits between the flange lc and the slide 6 t make a tight joint and to keep ont the wind.

IOO

In applying my invention I prefer to construct one edge of the sash, preferably either the top or bottom, as shown in Fig. 4, where 7 is the slot in which the glass is slid vertically, after which the edge of the sash is closed by means of the transverse sliding cap 8, engaging and inclosing the edges of the sash 3. When the window is closed, the piece 8 is locked in place, its ends being prevented from moving by the sides of the frame l. When it is desired to replace the glass, however, the piece S may be slid off from the frame 3, thus opening the slot in which the glass is held, and the glass can be then slid out and replaced. The glass is preferably held in the sash by inwardly-curved sheetmetal beads 9, which extend around the periphery of the glass and press the glass with a yielding pressure. At the side of the pane opposite the inwardly-curved bead is an inclined flanged strip 9, secured by clips 9b to the sheet l0, sufficient clearance being left between the strip and the sheet l0 to allow water of condensation to pass between them. The glass may be cemented or puttied or otherwise secured to the sash; but I prefer to secure it in the manner above described, which is illustrated in Fig. 4. Accumulated moisture or condensation runs down the inside of the glass and passes down behind the bead 9 and thence under the bottom edge of the glass, where it is carried outside the window by the sheet l0, forming the bottom of the sash. The inwardly-curved beads 9 are preferably made as shown in Fig. 3, both of ,thebeads and the side of the sash-frame being made from a single sheet of metal, the edges of which are bent to form the beads 9, the part of the sheet intermediate lthe two edges forming the sides of the sash 3 and the flanges which guide the sash and also the back which covers the face of the slide 6 when the window is closed. The back, the two sides, and the two beads form a hollow sash, which is substantially U-shaped in cross-section.

For cheapness and convenience in manufacturing I prefer to make the inner stopy 1f of the upper sash independent of the windowframe. In this case the stop is provided with a flange 1d, secured by means of bolts le to the side of the frame l.

To give greater stiffness and holding power to the beads 9, I provide a strip 1l of sheet metal having its edges rolled into the form of beads lla. The beads of this strip are then telescoped with the beads 9 by which they are held. The strip 1l thus prevents the beads 9 from springing apart and gives great strength to the metal sash.

What I claim is- 1. In combination with a windowframe and a sash mounted therein; a pair of slides vertically movable between the sides of the sash and the sides of 'the frame; inwardlyprojecting pins secured to the lower ends of said slides; recesses in the lower ends of the side members of the sash adapted to engage said pins; a pulley rotatably mounted on each vertically-movable slide above the pins; a pair of sash-cords carrying counterbalanceweights and secured to the sides of the window-sash at points substantially midway the height of the sash; said cords extending vertically upward in the rear of the pulley-A grooves when the sash is vertical, and adapted to pass under said pulleys and to draw up the counterbalance-weights when the sash is tilted out from the frame.

2. In combination with a window-frame and a sash mounted therein; a pair of slides vertically movable between the stops, the sides of the sash and the sides of the frame; inwardly-projecting pins secured to the lower ends of said slides; slots in the lower ends of the side members of the sash adapted to engage said pins and a pulley rotatably mounted on each vertically-movable slide above the pins, substantially as described and for the purposes set forth.

3. Awindow-sashhavingits sides composed of a sheet-metal strip of substantially U- shaped section, the sides of said strip being bent back upon themselves and having their inner edges curved inwardly to yieldingly hold the pane of glass, substantially as described.

4. The lower member of a window-sash comprising a sheet of metal underneath the lower edge of the pane, theinner edge of said strip being flanged upwardly and having its upper end curved inwardly to form a bead to yieldingly hold the lower edge of the pane, and an inclined strip on the opposite side of the pane, all forming means whereby the lower edge of the pane is held yieldin-gly and condensation from the surface of the glass is carried underneath the edge of the pane and delivered outside the window, substantially as described.

5. In combination with a window-frame; a pair of oppositely-placed slides vertically movable between the stops of said frame; a tilting sash mounted between said slides and pivotally connected to them near its lower end; and a pulley mounted on each slide above the pivotal connection, substantially as described.

G. In a window, the combination with a tilting sash; of a pair of counterbalancecords secured to said sash and carrying balance-weights at their outer ends; of a pair of pulleys mounted at the side of the casing and engaging said cords when the sash is tilted outwardly, but permitting the cord to pass freely back of said pulleys and not in contact with them when the sash is raised vertically.

In testimony whereof I affix my signature in presence of two witnesses.
