Application October 31, 1949, Serial No. 124,589

2 Claims.

The invention relates to a window sash fitting, and more especially to a removable sash assembly for old and new windows.

The primary object of the invention is the provision of an assembly of this character, wherein its elements are prefabricated, and in this connection such elements can be readily and easily mounted in a window frame, either old or new, so that the sash will be balanced for sliding adjustment without the use of weights, chains, cords, or the like, and also that such sash may be conveniently removed from the window frame, without requiring the use of tools or the detachment of any part of the said window frame.

Another object of the invention is the provision of an assembly of this character, wherein it is novel and unique for the holding of the sashes of a window in place in its frame, yet permitting their removal therefrom with ease and dispatch,

the sashes being readily slidable when installed so that the same may be adjusted in the opening and closing of the window.

A further object of the invention is the provision of an assembly of this character, wherein each sash carries two sash balancers, these being essential for the removable fitting of the sash to the window frame and provide an equal tension at all times on the window jamb itself whether the sash is in open or closed position, while equally essential to the removable character of the sash :`l

is the fact that the slide rail from which the sash is disengaged is set at a slight angle of about l5 degrees to allow for positive clearance of the sash from the window frame.

A still further object of the invention is the provision of an assembly of this character, wherein the same is a knock-down type, and involves a minimum number of parts, so that such assem bly can be set up with ease and dispatch.

A still further object of the invention is the provision of an assembly of this character, which is simple in construction, thoroughly reliable and efficient in the working thereof, strong, durable, neat and attractive in appearance when set up, assures quick and easy removal of the sash from a window frame as well as replacement, and inexpensive to manufacture and install.

With these and other objects in View the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation, partly broken away at intervals of a window frame with the removable sash assembly in accordance with the invention.

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure l looking in the direction ef the arrows.

Figure 3 is an exploded fragmentary plan view of a modified form of sash assembly in accordance with the invention.

Similar reference characters indicate corresponding parts through the several Views in the drawing.

Referring to the drawing in detail, A designates generally a window-frame, wherein slides the upper and lower sashes B and C, respectively, the latter being of the usual well known construction with the slight exceptions as will be hereinafter more fully described.

The said window-frame A is provided on its inner side faces with the usual parting stop I0, the blind stop II, and the front stop I2, respectively, between which the sashes B and C operate. The meeting rails of each of the sashes B and C are channeled as at I3 and I4, respectively, in matched relation and correspondingly to the parting strips or stops I0, the channels I3 being of greater depth than the channels I4, so that such sashes B and C can be shifted crosswise of the window-frame A to enable the removal of such sashes or the replacement of the same after removal from the window-frame,

At the right-hand inner face of the windowframe A between the stops I0, Il, and I2, are the prefabricated inserts in the form of strips I5, each having its exposed surface set at an angle of approximately 5 degrees, as at I6, to allow for positive clearance of the sash cooperating therewith from the Window-frame A as will be clearly apparent from the drawing. Intermediate of this surface I6 is a semi-circular bead Il which is coextensive with the longitudinal extent of the strip l5, the bead being approximately one-eighth of an inch in depth. The spaces between the stops I0, II and I0, I2, as well as the spaces on either side of the stop 23 form guide rails or spaces in which the sashes slide.

The vertical side members I8 of each of the sashes B and C at their outer faces meeting the rails or strips I5, each is angled as at I9 correspondingly to the surface I6, and such angled surface I9 has intermediate thereof a longitudinally directed semicircular groove 2Q receiving the bead Il. The side members I8 are constructed in the manner just mentioned only at the righthand side of the window-frame A, while the vertical side members 2| of the sashes B and C at the left-hand side are of the usual construction or formation, excepting the channels I3 as heretofore mentioned.

Installed in each vertical side member 2l at the left-hand side of each sash B and C is a pair of spaced upper and lower sash balancers 22 which frictionally contact the left-hand side of the window-frame A when the said sashes are tted thereto, and maintain these sashes to normally have the beads il interfitting the grooves 20 for sliding engagement of such sashes in the frame A and to hold the said sashes B and C in adjusted positions Without the use of weights, cords or the like as is customary for hanging in the windowframe A. The said balancers 22 keep both sashes B and C snug against the sliding rails and in this manner eliminates the need for weather stripping on one side of the window.

Now, when it is desired to remove either or both sashes B and C from the window-frame A it is only necessary to push such sashes to the lefthand side of the latter to have the bead I1 at the right-hand side of the said window-frame clear the channel or groove 20 and on outward swinging movement the sash will become removed from such window frame.

In Figure 3 of the drawing there is shown a slight modification of the assembly constructed Yin accordance with the invention, wherein the right-hand jamb side of the window-frame has the parting stop 23, the angled surfaces 24 and beads 25, respectively, involved in a single unit 26, and in both the preferred and modiiied forms of construction, each can be manufactured as a kit, prefabricated and disposed of for adaptation to old or new windows, the sashes being machined for cooperative tting to the kit.

What is claimed is 1. The combination of a window frame and a pair of sliding sashes therein, pairs of permanently fixed blind stops and front stops afxed to the window frame on the front and rear faces thereof, respectively and extending the entire length of the frame, and a pair of permanently amxed parting stops on the opposite sides of the frame, said pairs of blind stops, front stops and parting stops forming two pairs of sliding rails facing each other in juxtaposed position, said pair of sashes having facing channels for loosely engaging the ends of said parting stops whereby either of said sashes may be moved parallel to a line extending between said parting stops, the sliding rails at one side of said frame each having a bead and a portion of the sashes engaged in said last named rails, each having a groove engaged by its corresponding bead, said last named sliding rails each having its exposed surface set at an inclination to a vertical plane which is at right angles to the plane of its sash, and to form an angle with the plane of the other pair of sliding rails, whereby to allow for clearance of the sash during its removal from the window frame, the opposite portions of the sashes from those having grooves having plane surfaces engaging plane surfaces on their corresponding rails, and at least two spring pressed members housed in each sash for engaging the plane surfaces of the said rails, the said sashes being of greater Width than the distance between the innermost portions of the opposed sliding rails and less than the distance between the outermost portion of those rails accommodating the plungers and the innermost portions of the opposite rails whereby to leave spaces between the sides of the sashes having said spring pressed members and the rails engaged thereby to permit removal of the rails Without disturbing said blind stops, front stops and parting stops.

Z. The combination of a window frame and a pair of sliding sashes therein, pairs of permanently fixed blind stops and front stops affixed to the window frame on the front and rear faces thereof, respectively and extending the entire length of the frame and a pair of permanently aixed parting stops on the opposite sides of the frame, said pairs of blind stops, front stops and parting stops forming two pairs of sliding rails facing each other in juxtaposed position said pair of sashes having facing channels for loosely engaging the ends of said parting stops whereby either of said sashes may be moved parallel to a line extending between said parting stops, the sliding rails at one side of said frame each having a bead and a portion of the sashes engaged in said last named rails, each having a groove engaged by its corresponding bead. said last named sliding rails each having its exposed surface set at an inclination to a vertical plane which is at right angles to the plane of its sash. and to form an angle with the plane of the other pair of sliding rails, whereby to allow for clearance of the sash during its removal from the window frame, the opposite portions of the sashes from those having grooves having plane surfaces engaging plane surfaces on their corresponding rails, and at least two spring pressed members housed in each sash for engaging the plane surfaces of the said rails, the said sashes being of greater width than the distance between the innermost portions of the opposed sliding rails and less than the distance between the outermost portion oi those rails accommodating the plungers and the innermost portions of the opposite rails whereby to leave spaces between the sides of the sashes having said spring pressed members and the rails engaged thereby to permit removal of the rails without disturbing said blind stops, front stops and parting stops, said spring pressed members including a pair of spring pressed plungers having ilat faces for engaging the plane surface of said rails.
