4 Claims.

This invention relates to storm and screen sash for windows, the object being to provide a pair of metal frame members for glass or screen fabric that are slidably supported in the frame members after the manner of the usual double sashed vertically slidable windows, the frame being so constructed that the sash may be raised .or lowered and, due to a peculiarity 'of construction'of the supporting frame, being removable therefrom thus permitting a ready change from screened to glassed sash' for use at different seasons of the year.

Other features of the invention reside in the construction of the sash frame for the glass or screen member wherein a comparatively narrow rail is provided and thus permitting the frame portions in which the sash slide to fit the usual space between the screen stop of the window frame and the outer face thereof.

A further feature of the invention resides in the construction of the sash rail permitting thesame to be varied in length to conform to the width or length of the window opening.

These and other objects and novel features of the invention are hereinafter more fully described and claimed, and the preferred form of construction is shown in the accompanying drawings in which Fig. 1 is a view showing a window opening provided with my improved storm-or screen sash and frame. v

It has heretofore been common practice to provide a screen frame or a glassed storm sash which fits in the frame of a window and against the screen stop. A storm sash of this character when secured in place does not provide for ventilation, and one of the objects of my invention is to pro vide a frame in which sliding sash are mounted, which frame may be permanently secured in the space between the screen stop and outer face of the window frame and by making the sash frame ofmetal and narrow in width, suflicient space is provided to permit the sash to be raised or lowered and all within the space that has heretofore been used to support a single sash or screen frame.

In the accomplishment of the several objects of this invention, I have provided sheet metal frame members I of channel form in cross section throughout the greater part of the length thereof having the two side flanges 2 and 3, the inner flange 3 seating against the outer face of the screen stop 4 secured'to the window frame 5 in which the ordinary window sash 6 and. I are slidably mounted.

The sash 5 and 6 are here shown as the usual wood type of glassed sash but may be of any character, the only requirement being that a screen stop or other element be provided between the regular sash of the window frame and my improved metal frame and sash members and. both the screen stop 4 as well as my metal frame I may be secured to the window frame 5 by means of screws indicatedat 8 and 9 in Fig. 3.

There is a channel frame element I on each of the opposite sides of the window frame 5 and the outer flange 2 'of both members is interrupted to provide a space indicated at ID in Fig. l. The width between the flanges 2 and 3 is somewhat greater than the combined thickness of the upper and lower sash elements II and I2 as will be understood from Figs. 2 and 3. The sash rails are of sheet metal having a construction hereinafter described and providing U channels to receive glass I3 or a screen frame member, the edges of which fit in these rails and a packing element I4 is provided around the edge of the glass so that the glass tightly fits the frame and leakage of air around the glass is prevented. The screen member can likewise be fixedly supported in the channels in place of the glass. In the upper part of each of these channel members I are provided leaf springs I5,. I6 which bear against the sash rails, there preferably being a spring element It in the channel members I to engage the outer sash at about the point of junction of the upper edge of the lower sash I2 with the lower edge of the upper sash I I.

By the spring elements the upper sash is held tightly in engagement with the inner flange 3 of the channel member in which it is slidable and the sash at the junction of the upper and lower edges thereof also held in tight engagement while the lower edge of the lower sash I2 is brought to practically tight engagement with the window sill. Under the arrangement described, the lower or upper sash I I and I2 may be raised or lowered and still maintained under spring pressure.

In order -to remove the sash from the frame a space ID in the outer flange 2 of each side frame member is provided. The lower sash I, in my construction, is the outer sash member and not the inner sash member as is the case with the window sash 6 and 1. In order to remove the sash the space I0 is provided in the outer flange 2 and by raising the lower sash until the-bottom rail is above the uppermost point of the bottom portion 2 of the flange 2 it may then be moved outwardly and the sash by downward movement withdrawn through these openings In from the channel members I. The upper sash can then be removed in like manner. The members I remain in permanent position and either glassed or screened frames may be introduced thereinto by first introducing the upper sash to the position occupied by the sash II in Fig. 2 and thereafter a lower sash introduced to behind the spring members It and moved upwardly in the upper portion of the channel until the lower rail of the screen sash is above the upper end of the short portions 2 of the flange 2 and thereafter moved inwardly and thence downwardly tooccupy the'position of the lower sash l2 as shown in Fig. 1. v

It will thus be seen that the side frames I can be permanently -mounted in a window frame on the outer face of the screen stop 4, the storm sash readily removed for the summer period and screen sash introduced which in turn may be removed to permit introduction of the storm sash for the winter period. I

It is desirable that the rails of the sash elements and I2, whether of the glassed or screened type,

should be as narrow as possible to avoid so great a width of the channel members l as to project beyond the face of the window frame and thus they are made comparatively narrow with a packing element for the glass as described and, due to the fact that windowframes are not made to an exact size and the fact that the sash member should be a close fit in the frame members I provide the rails for the periphery of the glass or screen of U form in cross section as shown at 3 in Figs. 2 and 3 or at H and H in Figs. 4 and 5. These may be all of the same length if the frame is to be square and each have the tapered ends l8 and Hi. The base of the channelmember l1, as shown in Fig. 4, is continued to form a tongue 20 and at the opposite end is formed with a series of slots 2|, 2| and the rail l1, as shown in perspective in Fig. 5; should have the tongue element 2!] turned downwardly within the end of the base of the contacting member l1 and inrails described that they may be placed overthe edge of a glass for instance after having first, if necessary, cut the rails to' the desired length and without use of putty or like means the four rails are tightlybound together to the degree permitted by the mitered ends whereby the glass is securely held by the metal rails. With a screen fabric the edges thereof may be reinforced if desired in any approved manner to fit into the channel members l1 and II.

A different form of construction, particularly in relation to the fastening means of the meeting ends of the side and end sash rails is shown in Fig. 7; In this form of the invention an end rail 40 may be provided with an aperture 4| to receive an end 42 of the tongue 43. In this form the tongue is not an integral part of the rail and to secure the same to' the rail-4|l one end thereof is inserted through the aperture 4| and bent over the outer face of the member 40 and the body part extends outwardly through the open end of the channel 40 and is then bent downwardly at a right angle thereto as shown by the portion 44 and the terminal end 45 may be inserted through the aperture 46 provided therefor in the side rail 41. These rafls 40 and 41 each have a tongue of the character shown'in Fig. 7 at one end and the opposite end has a series of apertures which permits the same to be cut to length for different sizes of the sash as described relative to the form of rail shown in Fig. 4.

The end 45 of the tongue 43 is placed through the necessary aperture of the rail 41 to bring the mitered ends of the rails 40 and 41 to tight engagement ,and the said end 45 is then turned upwardly over the member 40 as indicated by the dotted lines; This arrangement is preferable in some instances over that shown in Fig. 4 in which latter figure the tongue is shown'as an integral part of the rail. Such integral part,

i 1 through repeated use, may become broken in which case the entire rail would require to be discarded. By the structure shown in Fig. '7, some material is saved and if the tongue becomes broken the parts connected with the rail may be removed and a new tongue inserted. It

is also to be noted'that the portion 42-may be spot-welded in place if desired. The invention therefore is not limited to any special form or the window as has heretofore been the case.

By use of the adjustable lengths of rails for formation of thesash elements the width of the same may be made to correspond to the spacing of the frame elements I and thus there is a cooperative relation between' the sash rails formed to permit variation in length in conjunction with the two separate and independently secured frame elements whereby a storm or screen sash and frame arrangement is provided that is adjustable to comparatively slight variation in width of openings in the window frame in which the same are mounted.

It isalso believed evident that the structure is v of a comparatively simple and inexpensive nature and that the various objects of the invention are attained by the construction described, it being understood however, that various changes may be made in the construction without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus fully described my invention, its 1 utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is- 1. A sash and frame construction (for use in conjunction with a window frame comprising a pair of channel members independently mounted in opposite vertical sides of the window frame, a pair of sash slidably mounted in the said channel members, spring elements in each channel member bearing against the sash rails, the outer flange, of each channel member being cut away intermediate its length permitting the lower sash element to be removed by first-raising the sash element until the bottom rail is above the lower edge of the cut out portion, the spring members permitting the bottom edge of the sash to be moved outwardly through the cutout portions of the channel members and thence downwardly to remove the same and the second sash being removable in the same manner and introduced to position in the reverse manner, the arrangement of the parts providing that the lowermost sash of the pair is on the outer side of the uppermost sash of the pain.

2. A sash construction for use in conjunction with a window frame comprising a pair of U- shaped' channels independently mounted on op posite vertical sides of the window frame, the open sides of which face each other, a pair of sash for mounting in the said channel members, said sash members having metal rail elements, and when in the'respective upper and lowermost positions, have the lower rail of the upper sash and the upper rail of the lower sash occupying substantially the same horizontal plane, spring means in the said channels for holding the sash in the channel frames in slidable relation therein, the outer flange of each of the channel members intermediate their length having an opening to permit removal or introduction of the sash members in the erected channels substantially as described.

3. A storm or screen sash and frame construction for window frames having a screen stop spaced to the rear of the outer face of the window frame comprising a pair of U-shaped metal channels secured to opposite sides of the window frame having inner flanges engaging against the screen stop, a pair of metal sash having opposite sides engaging in the channel member in slidable relation, the widthbetween the flanges of the channel frames being greater than the combined width of the two sash elements and slidable therein, a

plurality of spring elements secured to the outerflange of each channel member andengaging the sash rails respectively slidable therein and holding the meeting rails of the sash in comparatively tight engagement when in the closed position, the outer flange of the channel members being cut away forming an opening above the lower end thereof through which the'sash elements may be removed. p

4. A sash construction for use in conjunction with a window frame comprising a pair of U shaped channels independently mounted on respectively opposite vertical sides of the window frame with the open sides facing each other, a pair of sash for mounting in the said channel members, the sash having metal rail elements of such form that when in the respective upper and lowermost positions the lower rail of the upper sash and the upper rail of the lowersash occupy substantially the same horizontal plane in face contact, spring means positioned to apply pressure to the said cross rails to thereby maintain the same in face contact when the sash are in closed relation, the outer flange of each of the channel members having an opening, the upper end of which terminates below the plane of the meeting rails and through which the bottom cross rail of the lower sash may be moved outwardly and thence downwardly to remove the same and the second sash being removable in substantially the same manner and both re-introduced to position in the channel members in the reverse manner, said channel member between the inner and 40 outer side flanges being of a width to receive both said sash and spring means.
