This invention relates to a window and more particularly to a double hung window.

The primary object of the invention is to improve the ventilation in a room or like enclosed space.

Another object is to assure durability and weather tightness in a double hung window structure.

A further object is to hold the sash of the window against movement even though it may be part way open and thereby frustrate any attempted intrusion into a closed space without impairing the ventilation thereof.

The above and other objects may be attained by employing this invention which embodies among its features a window frame, a Xed sash midway between the upper and lower ends of the frame, sashes movable in the frame for closing the spaces between the upper and lower edges of the fixed sash and the upper and lower ends of the frame and coupling lmeans between the upper and lower sash to cause them to move in unison.

Other features include means selectively to couple and uncouple the lower sash from the coupling means to permit the lower sash to be raised or lowered independently of movement of the upper sash.

Still other features include locking means to hold the sashes in various adjusted positions.

Referring to the drawings in detail the frame of this improved window comprises a sill designated generally 20, a pair of Stiles each designated generally 2| and a lintel designated generally 22.

The sill 20 comprises a sheet metal bar of sub-` stantially Z-shape in cross section the web- 23 of which is provided adjacent opposite side edges with oppositely bent longitudinal flanges 24 and 25. The flange 24 forms the outer apron of the window frame and the flange 25 is provided at each end with an extension 2B. These extensions are bent to extend in parallel planes which lie perpendicular to the flange 25 along opposite end edges of the web 23.

The lintel 22 comprises a channel member 27 of a length substantially equal to that of the sill 2) and extending between the opposite side flanges 28 of the channel 27 are end walls 20 which cooperate with the flanges 28 and the web of the channel in forming a boX-like structure.

Each stile 2l is formed of a channel shaped body 30 the upper end of which is adapted to t between the side flanges 28 o-f the lintel against Van end wall 29 and the lower end of each stile is adapted to rest on the web 23 of the sill against an extension 25. The free edge of the outer flange 3| of each channel shaped body 30 is folded back upon itself as at 32 to form a reinforcement andnish bead and the upper end of the finish bead of each outer flange terminates in a plane which coincides with the plane of the lower edges of the side flanges 28 of the lintel. Formed in the web of each channel shaped body 30 between the flanges thereof is a pair of longitudinally extending spaced parallel grooves 33 for a purpose to be more fully hereinafter eX- plained.

A parting strip designated generally 34 is fitted in each channel shaped body 30 and each parting strip comprises a substantially channel shaped strip of sheet or extruded metal having a web' 35 which is offset adjacent one side flange to form a stop 36. Each side ange 31 is inwardly offset as at 38 and the longitudinal edge of each offset portion 38 is fitted into a groove 33 in one of the channel shaped bodies 30 to hold the parting strip in proper position therein. The offset portions 38 cooperate with the flanges of the channel shaped body in forming longitudinally extending runways A and B for the sash carriers .to be more fully hereinafter described.

Formed in each offset portion 38 of each parting strip 34 adjacent its upper end is a longitudinal slot 39 and formed in each offset portion 38 intermediate its ends is a similar longitudinal slot 40.

Carried by the web portion of each channel shaped body 39 adjacent its upper end is a spindle 4| upon which a grooved sash pulley 42 is mounted to rotate and a similar spindle 43 is carried by each web portion of each channel shaped body 3D intermediate its upper and lower ends. A sash pulley 44 is rotatably supported on each spindle 43 and these pulleys extend through the adjacent slots 39 and 40 as will be readily understood upon reference to Figure 7. A suitable endless sash cord or cable 45 is trained over the pulleys 42 and 44 on each side of the window frame and these cables or cords are coupled to the sash carriers of the upper and lower sash as will be more fully hereinafter explained.

Mounted for Vertical sliding movement in the runway A of each stile 2| is a sash carrier 46 and a similar sash carrier 41 is mounted to slide in each runway B. These sash carriers are substantially identical in construction and each is formed of a channel section comprising a web portion 48 (Fig. 10) having integral side flanges 49. A bridge piece 50 extends transversely adjacent one end of each channel section between the side flanges 49 and each bridge piece is formed with a sash cord or cable receiving notch A suitable stop 52 is clamped to each cable 45 as by a set screw 53 against the upper and lower side of each bridge piece 5| so that the cables 45 and sash carriers 46 and 41 on each side of the frame will move in unison.

As shown in the drawings the sash carriers 46 for the lower sash have their webs 48 disposed against the inside anges of the channel members 39 while the sash carriers 41 have their webs 48 disposed against the outside anges 3| of the channel members 39. Formed in the side anges 49 of the lower sash carriers 46 on opposite sides of the frame are longitudinally spaced bolt receiving openings 54 the purpose of which will be hereinafter explained.

Seated on a suitable angle bracket 55 (Fig. 2) fixed to each parting strip intermediate its ends is the lower edge of a relatively fixed sash 56 which is of such a width as to fit between the parting strips 34 on opposite sides of the window frame and rest against the beads 36 thereof. A binding strip 51 extends along each vertical edge of the sash 56 and pivoted as at 58 to the inner side of each binding strip 51 is a latch 59 having a tongue 60 which is adapted to t into a slot 6| formed in an adjacent parting strip 34. A suitable finger hold |52A projects outwardly from the edge of each latch 59 opposite the tongue 60 to facilitate the manipulation of the latch.

Mounted for vertical sliding movement in each runway A is a side channel 63' of the lower sash 64. The web of each channel 63 bears against an adjacent leg 49 of a lower sash carrier 46 and tted to the upper edge of the lower sash 64v ad'- jacent each side edge thereof is a tubular housing 65 in which a bolt 66 is mounted to slide along an axis which lies perpendicular to the plane of movement of the sash. The bolts 66 when projected are adapted to enter opposed Vopenings 54 in the sash carriers on opposite sides of the sash, so as to cause the sash 64 and its carriers 46 to move in unison. A knob 61 projects radially fromeach bolt 66 and through an L-shaped slot 68 in its respective housing so as to facilitate its manual projection or retraction. Obviously by the simultaneous retraction of the bolts the lower sash may be raised or lowered without imparting movement to the carriers 46 and. by projecting the bolts 66 into the holes 54 at different elevations, the sash 64 will be held at different elevations relative to its carriers 46.

An upper sash 69 carries, along opposite side edges, side channels 19 which slide in the runways B in unison with the sash carriers 41. Each web of each channel 19 lies against a flange 49 of a carrier 41 and Secured to each carrier 41 immediately below and in abutting relation with the lower edge of the upper sash 69 is a supporting bracket 1| so that when the carriers 41 are moved by the cables the sash 69 will move in unison therewith, it being understood that when the carriers 41 move downwardly, the sash 69 will follow under the force of gravity.

In order to lock the lower sash 64 and the upper sash 69 against movement I provide one of the stiles 2| with an opening 12 which is surrounded with an outstanding internally screw threaded socket 13 for the reception of a set screw 14, the inner end or point of which is adapted to impinge against the web 48 of one of the sash carriers 46 (Fig. 6). It will thus be seen that both the lower and upper Sashes may be locked in any adjusted position and against relative movement. It is to be noted, however, that while the carriers 46 and 41 will be held against movement and the upper sash 69 so held, the lower sash 64 will be susceptible to vertical movement by extracting the bolts from the openings 54. In this way a wide variation of Window opening may be achieved.

As shown in Figure 2 the lower sash 64 when closed overlaps the lower edge of the xed sash 56 and the upper sash 69 when closed overlaps the upper edge of the fixed sash 56. A weather v tight junction is eiected between the Xed sash and the-movable sashes through the medium of meeting rails 15 which in the present instance take the form of molded strips of soft rubber or a synthetic substance fitted over the upper land lower edges of the sash 56 and bearing lightly on the inner surface of the sash 69 and on the outer surface of sash 64.

While the frame as a whole may be prefabricated as a unit by permanently joining the opposite ends of the sill 2|] with the lower ends of the stiles 2| and opposite ends o the lintel with the upper ends of the stiles, I may nd it advantageous, for shipping purposes to so construct the frame that it may be shipped in a knocked down condition and to this end I provide the web 21 o the lintel 22 near each end and adjacent each side flange 29 with a slot 16 and in the sill 29 I provide similar slots. These slots are adapted to receive hook shaped ears 11 formed integral with and at the upper and lower ends of the side flanges of the channel 36 forming the Stiles 2|. After so entering the ears 11 in the slots 16 a screw is introduced through a countersunk opening 19 formed in each end wall 29 of the lintel and each extension 26 of the sill to enter an opening 19 formed in each channel member 39 near each end.

In the modication illustrated in Figures 11 and 12 the lower ends of a stile designated generally 89 is fixed to each end of a sill designated generally 8| while the upper end of each stile is connected to a lintel (not shown) which corresponds in all respects to the lintel previously described. The sill 8| like that previously described comprises a web 82 having along one longitudinal edge a downwardly extending apron 83. The sill also carries at opposite ends, end walls 84 carrying, at the ends opposite the edge of the sill carrying the apron, inturned ilanges 85. Extending along the edge of the web 82 opposite that carrying the apron 83 are longitudinally spaced aligning hinge barrels 86. A flap 8l carrying longitudinally spaced hinge barrels 88 which fit between the hinge barrels 86 is pivotally connected to the web 82 through the medium of a hinge pin 89, and welded or otherwise attached to opposite ends of the flap are arms 80 which when the window is closed lie adjacent the inner flanges of the stiles 8D.

Carried at the upper end of each arm 90 is a bracket 9| carrying upwardly extending spaced ears between which one end of a link 92 is pivoted as at 93. A bracket 94 is xed to each stile 80 in spaced relation to the sill 8| and has pivoted thereto as at 95 a pair of links 96 which in turn are pivoted as at 91 to the link 92.

Each stile 80 comprises a channel member having inner and outer flanges 98 and 99 between which is located a parting strip I corresponding in all respects to the parting strip 34 previously described. The parting strip of each stile cooperates with the ilanges 98 and 99 in forming inner and outer runways C and D in which sash carriers |0| corresponding to the sash carriers previously mentioned are mounted to slide. A xed sash |02 corresponding to the fixed sash 56 is mounted between the stiles 80 on the parting strips |00 and mounted to slide on the sash carriers in the runway D is an upper sash (not shown), while a lower sash |03 is adapted to slide in the runway C with the sash carriers Il. Like the sash carriers 46 the carriers |0| for the lower sash |03 are provided with longitudinally spaced bolt holes |04 for the reception of bolts |05 corresponding to the bolts 66 previously described. The lower portion of each ilange 98 is cut away as at |06 from the sill to the top of the sash |03 so that when the bolts |05 are retracted with the sash 03 in lowered position, the sash may be swung outwardly as shown in full lines in Figure 12 to serve as a window ventilator. Of course, when the sash |03 is in vertical position as illustrated in the dotted lines in Figure 12, it will align with the runway C and may be moved upwardly therein.

In use the sashes 64 and 69 serve to counterbalance one another and when the bolts 66 are projected into the lowermost openings 54 in the carriers 46 both the upper sash 69 and the lower sash 64 may be moved into a position wholly to overlie the xed sash 56, thus effecting a maximum of ventilation. Should it be desired to raise the lower sash 64 without moving the upper sash 69, the bolts 66 may be withdrawn from the lowermost openings 54 in the carriers 46 and the sash 64 raised and again locked in elevated position by projecting the bolts into any of the openings 54 above the lowermost. Both the upper sash 69 and the lower sash 64 may be locked by turning the set screw '|4 in a direction to cause the point thereof to impinge on the carrier 46 with which it aligns and thus it will be seen an infinite number of adjustments may be had.

In using the modied form of the invention illustrated in Figures 11 and 12 it is evident that not only may the upper and lower sashes be opened to the desired degree and locked by the mechanism previously described, but that the lower sash |03 when in its lowered position, may be swung outwardly to serve as a window Ventilator simply by withdrawing the bolts |05 from the openings |04 in the sash carriers |0| While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

1. In a window of the type having vertically movable upper and lower sashes, a window frame which includes vertically disposed stiles each having spaced vertical runways therein with the runways of one stile being opposite the runways in the other stile, vertically spaced pulleys mounted on each stile with opposite portions of their peripheries disposed in adjacent runways in their respective stiles, cables trained over the pulleys on the respective stiles, elongated channel shaped sash carriers slidably mounted in the runways in spanning relation with the pulleys and cables therein, means carried by the cables and engaging the sash carriers for moving said sash carriers as the cables are moved, and sashes mounted in the runways and connected to the sash carriers for movement in unison therewith.
