This invention relates to an improvement in a sash window and more particularly to one which may be manipulated to facilitate cleaning or to change or control ventilation.

The preferred embodiment of the invention discloses a unitary structure which may be mounted in a window opening and which consists of a frame, guides and sash.

The principal object of the invention lies in the provision of a window structure having an insertable or removable frame in which is mounted' a sliding sash.

Another object of the invention lies in the provision of a window construction, the sash of which may be. swung inwardly for the purpose of facilitating cleaning.

-A further object of the invention lies in the provision of a device comprising a sash and guide frame which may be assembled by the manufacturer and installed as a unit in a window open- Another and further object of the invention lies in the provision of a structure of this kind which is easily manufactured and installed and which, as a result, is economical to produce.

Other and further objects of the invention may be more clearly understood from a consideration of the following specification which is taken in conjunction with the accompanying drawings, and in which Fig. 1 is a front elevation of one modification of this invention in position of use;

Fig. 2 is an enlarged fragmentary horizontal sectional View of a frame, rails and sash, being taken substantially on the line 2--2 of Figure 1;

' Fig. 5 is a vertical sectional View, showing the removable frame;

- Fig. 6 is an enlarged vertical sectional view, taken substantially on the line 6-6 of Figure 2, showing the frictional engagement between sash and frame; and

Fig. 7 is a horizontal sectional view, similar to Figure 2, showing a slight modification of the structure of that figure.

' Referring to the drawings, one modification of the invention is shown mounted in a window opening, the walls of which are generally indias desired, or may be formed from wood or, 6

in fact, any convenient material. The vertical walls of the window opening are fitted with rails 16 which, through inner and outer flanges 1'7 and 18, are secured to the Wall. Connecting these flanges is an inner straight portion 19 having an inwardly projecting rib 21. The rib, along the inner face 22 in the present showing, is formed with a slight recess 23, the purpose of which willhereinafter be set forth. Formed in the lower ends of the portions 19, commencing adjacent the covering 12 and rib 21 are slots-24 which curve upwardly and inwardly and terminate in enlarged offset openings 25. The slots 24 are for the purpose of mounting a removable frame which supports the sash. The upper horizontal walLwhich 7 defines the window opening, is fitted with a metal. or other suitable plate 26. This plate is preferably identical with that of the rails 16, being formed with an inwardly projecting rib 2'7, connected with an extended flat portion 28. Referring to Figure 3, it will be noted that the ribs 27 and 21 coincide to form a continuous rib about three sides of the window opening.

The frame 39, comprised of rails 31 and stile 32 joined together to form a downwardly opening U-shaped member, supports and guides oneor more sashes. The rails 31 are each formed with inwardly projecting ribs 33 which terminate in flanges 34 engageable with the inner flanges 17 of the rails 16. These ribs extend the full length of the rails 30 and define the inner longitudinal edge thereof. The outer longitudinal edge of each of these rails terminates in a flange 36 which, when the frame is mounted in the window opening, lies in the recess 23 of the face 22.

Between the flange 36 and rib 33 is located a sash guide 37 which consists of a longitudinally extending outer portion 38 connected by flanges 39 which in turn are connected with flanges 40,

parallel with the face 38. Flanges 40 terminate in short flanges 41 which are parallel with the flanges 39. The guide 37 is joined to the rail 31 along the portion 33 in any suitable manner as by welding. It will be noted that the flanges 41 are not only spaced from the adjacent ribs 21 and 33 but from the base wall of the rail 31 as well, thus forming pockets 43, access to which is had through openings 45. The stile 32 of the frame. 30 is formed with a downwardly projected portion 46 having flanges 4'7 and 48. 1 Flange 47 terminates in an offset flange 50 which is engageable with the room face of portion 26. Adjacent the lower outer portions of the rails 31 are pins 51 which project into slots 24 of the rails 16. These pins are fitted with enlarged heads 52 which prevent disengagement of the pins from the slots. The pins 51 and heads 52 may only be withdrawn from the slots 24 when moved upwardly into the offset openings 25, which terminate the upper ends of the slots 24.

Sashes 54 and 55 are mounted in the guides 37. Each sash is provided with outwardly opening rails 56 which are reinforced by outwardly opening channel members 57. The combined thickness of one wall of the rail and one wall of the channel is approximately that of the space between the fiange 41 and face 22 of the rib 21.

Attached to one side wall of the channel member 57 is a leaf spring 59 which, when the sash is in place frictionally engages one of the flanges 39 of the guide 37. Pressure of the spring against this fiange causes the inner face of one wall of the channel member 5'7 to engage the opposite face of the flange 39. The upper stile 61 of the sash 54 opens outwardly and is reinforced with a channel member 62. Similarly the bottom stile 63 of the lower sash 55 is reinforced with an outwardly opening channel member 64. The lowermost stile 66 of the upper sash is formed by two interengaging elements 67 and 68, the element 67 having a flange 69 spaced from a flange '70 of the element 68 to provide a full width horizontally extending recess '72. The upper stile '74 on the lower sash 55 p is provided with a recess '75 formed by spaced stripping 78 is located between the flanges 69 and 40 77. The formation and location of the trim for securing the glass 80 is common practice, forming no part of this invention and will not, therefore, be described.

It will be noted that the upper stile 61, when the upper sash 54 is in closed position, lies between the flanges 48 of the frame stile 46 and the rib 2'? of the portion 26. Stile 63, when the lower sash 55 is closed, rests adjacent the shoulder 13 of the covering 12, being cut to fit the sloped portion 14.

Adjacent the upper portion of the movable frame 30 and mounted in the rib 33 is a locking structure which consists of a rotatable latch 81 mounted on a pin 82. The pin is supported in the flanges of the rib 33 and is arranged with one end projecting through the outermost flange. The exposed end of the pin is provided with an angularly shaped opening with which a key may be engaged to rotate the latch 81. A tapered slot 84 is formed in the rail 16 with which the latch 81 is engaged to lock the movable frame 30 in position within the window opening.

In Figure '7 of the drawings, is shown a slight modification of the previously described guide 3'7. In this instance, the guide 86 is joined to the central portion of the frame stile 31 in any suitable manner as by welding and is formed with flanges 8'7 and 88 which define recesses 89. In these recesses are located the leaf springs 59. The principal difference of this structure is in causing the springs of each sash to exert outward pressure, thus moving the adjacent stiles of the sashes into close engagement. The disclosure of Figure 2 shows the sashes being urged away from each other.

The assembly and installation of a device of this type is very easily accomplished. The window opening is lined, so to speak, with metal rails 16, sill covering 12 and upper stile or portion 26. These four elements are installed separately, being joined together and to the walls of the opening 10 in any expedient manner. The frame 30, guides 37 and sashes 54 and 55 may be assembled at the factory and installed as a unit in the window opening. The installation is accomplished by moving the sashes within a frame to a position substantially as shown in Figure 4 of the drawings, engaging the pins 51 with the slots 24 by projecting the heads 52 of said pins through openings 25. The frame may now be moved downwardly, pins 51 following the slots 24 until a point is reached where the stile 32 of the frame will move into position beneath the portion 26 and the flange 49 of the frame engages a flange of the portion 26. A key may now be inserted into the rectangular opening 83 of the pin 82 and when rotated causes the latch 81 to engage the wedge shaped slot 84. When both latches, one in each rail of the frame, are engaged with the rails 16 which define the window opening, the structure is complete and the sashes may be vertically reciprocated at will.

It is not uncommon to find a sliding sash having an arrangement which permits swinging inwardly to permit cleaning. It is unusual and novel, however, to arrange an upper and lower sash in a pivotal frame which, through the manipulation of one or more latches, may be swung inwardly to permit cleaning of both upper and lower panes of glass simultaneously. It will be noted that by means of this construction, it is possible to quickly install the window or remove it and also that the adjustability or removability in nowise affects the weather proofing features which prevail when the sashes are in closed position.

While applicant has shown and described but two modifications of the invention, he does not intend to be limited thereto since it is obvious to those skilled in the art that other modifications or adaptations may be made without departing from the spirit and scope of the invention as defined in the hereunto annexed claims.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is:
