WINDOW STRUCTURE.

Application led April 12, 1926. Serial No. 101,669..v

My invention' relates, more particularly,

to window structures ofthe type comprising vertically movable upper .and lower sashes which are offset one from the other to of each being moved throughout vthe eight of the window frame.

My primary objects are to provide a construction of window structure whereb the window sashes may be so manipulate ythat both sides of the window panes therein may be rendered readily accessible, more partic-l ularly, for washing from the inside 'of the o o l U window; to provide improvements in wm- `dow structures of the type above referred to, and more particularly of the typewherein the window sashes are "pivotally mounted in frames which slide u and down in the window frame, to the en that the same, or substantially the same, transparent areas lpresented by window structures of the common type, w1ll be presented in window .structures embodying myimprovements; to provide improvements in window structures of the eneral characterabove stated and resenting the features above referred to, to the end that window structures of the type referred to and as commonly provided, namely,.of such construction that the window sashes have no movement in the window frame other than an up and down movement, may be readilyv and economically rel 4vmodeled to embody my improvements, without reduction'of the transparent areas ofthe window structure. v

Referring to lthe accompanying drawmUs:-

Figure 1 is a face view of a window structure embodying my improvements, viewing the structure from the inside of the room. Figure 2 is .a vertical sectional view taken at the line 2-,-2 on Fig. 1 and viewed in the direction of the arrows. Fi ure 3 is a plan sectional view taken at the lme 3-3 on Fig. 1 and viewed in the direction of the arrows, this view showing by full lines the lower, inner, sash in lowermost closed position, and by dotted lines one of the positions occupied by this lower sash when swung inwardly, and the position occupied by the removable sash stop cooperating therewith to permit this sash to be swung inwardly. Figure 4 is an enlarged broken view taken at the line 4 on Fig. 3 and viewed in the direction of the arrow; and Figure 5, a perspective view of the u per sash and the -frame in which it is pivota y mounted.

ermit Referring to the articular construction shown, the window frame is represented at 6, the opposite lateral side walls 7 and 8 of which, contain vertical grooves 9 and 10, and 11 and 12, respectively, extending sub- \stant1ally the full height of the window opening, the grooves 1() and 12 being located .toward the outer side of the frame 6 and in parallel spaced relation to the grooves 9 and 12, respectively.

Slidable up and down in the grooves 9 and 11, is a frame 13 of general rectangular form and preferably formed of metalv adapting the side members 14 and 15 thereof and the top and bottom members 16 and 17 thereof, to be made relatively thin and still resent the desired strength. The side mem ers 14 and 15 are shown as provided adjacent their lupper and lower ends with lugs 18 and 19, and 20 and 21, respectively, at which this frame extends into the grooves 9 and 11 and by means of the side walls of which latter this frame is guided in its up and down movements, the upper lugs 18 and 2O servino as means for attachment thereto of the usual window sash cords for counterbalancing the weight of this window section. V The frame 13 is equipped with a window sash proper 22 which may be, and preferably is, formed of wood and is of a shape and size to fairly snugly fit within the opening provided by the frame 13. The-sash 22, which is equipped with a pane 23 of glass, is pivotally connected with the frame 13 to swing on a vertical axis, and to this end the sash 22 is rovd'ed, adjacent one lateral edge thereo namely, the right-hand edge in Figs. 1, 3 and 5, with lugs 24 and 25 containing vertically disposed openings therethrough and into which ldownwardly andv upwardly projecting pivoting pins 26 and 27 carried by lugs 28 and 29 provided on the top and bottom members 16 and 17 of the frame 13, extend, thereby permitting the sash 22 to be swung on the pivots thus provided into and out of the full line position shown in Fig. 3.

The window frame 6 at the edge thereof adjacent the pivots 26 and 27, is provided with a cleat 30 so positioned as to overlap `and form a tight joint between it and the adjacent vertical side member of the sash 22 when this sash is in the closed position shown by the full lines in Fig. 3, it being intended that this cleat be permanently secured in place. The window frame 6 at its los - section of the window.

opposite side is provided with a vertical cleat formed of an upper section 31 permanently secured to the window frame and a lower section 32 in vertical alignment with the section 31, but removably7 secured 1n place, as for example by hinging it to the window frame, as represented at 33. The cleat formed of the sections 31 and 32 cooperates with the adjacent edge portion of the sash 22 in the way describedof the cleat 30, the cleat section 32 extending slightly above the upper edge of the fr ame 13 when the latter is in lowermost positlon, as shown in Fig. 1.

Slidable up and down in the vertical grooves 10 and 12, is a frame 34 of the same construction as the frame 13, this frame being guided in the grooves 10 and 11 by lugs at its lateral sides as explained of the frame 13, the lower lugs of the frame 34 being represented at 35, it being understood that the upper lugs thereof, (not shown), would be connected with the sash-weight-cord lfor cooperation with the upper, outer sliding The frame 34 contains a sash 36`pivotally mounted therein as explained of the sash 22, the upper pivot of this outer sash beingrepresented at 37, and its pane of glass at 38. The window frame 6 is provided, between the vertical planes in which the respective window sections are movable, with parting strips 39 and 40. The parting strip 39 which extends the full height of the window opening, may be provided as a single section and permanently secured to the window frame. The parting strip 40 is formed of two vertically aligned strip sections 41 and 42, the lower edge of the section 41 extending above the upper edge of the frame 34 when the latter is lowered in the window frame to its lowermost position. The strip section 41 may be permanently secured to the window frame, if desired, whereas the strip 42 is provided as a removable section, and to this end it is preferably provided with a plate, or the like, 43, which depends below the lower edge of the strip 42 and is adapted to extend into a slot 44 in the bottom cross member of the window frame, the u per end of the section 42 preferably exten ing into a recess 45 provided between plates 46 secured to the lower end portion of the section 41 at opposite sides thereof.

The parting strips 39 and 40 are preferablv of such dimensions as to provide a close sliding fit between them and the window sashes. The window frame 6 at its front strip portions 47 and 48 overlaps the front surfaces of the vertical side members of the saslli136 and forms a close sliding fit therewit l It will be understood from the foregoing that the sashes 22 and 36 slide up and down in grooves provided at opposite sides of the window frame 6 and with the walls of which the sashes have relatively tight sliding fit thereby renderin the window structure substantially air tig t.

It will further .be understood that the sectional parting strip 40 and the cleat formed of the vertically aligned sections 31 and 32 form stops preventing the window sashes 22 and 36 from swinging inwardly, in the normal condition of the window structure, but by reason of their displaceable sections 32 and 42 permitting of such inward swinging of the sash as and for the purpose hereinafter described.

Assuming that it is desired both sashes 22 and 36 be swung inwardly on the frames 13 and 34 in which they are carried, as for example to permit of the ready cleaning of both sides of the window panes of the two sashes by a person standing on the floor, the operator, assuming the inside frame 13 Vto be in normal, lowered, position, swings the cleat sections 32 outwardly to the dotted position shown in Fig. 3, the operator first turning the turn button 31u to release the section 32, and thereupon swings the sash 22 inwardly as for example to the position shown by dotted lines in Fig. 3. The operator then raises the frame 13 and sash 22 to the top of the window frame and lowers the frame 34 and sash 36 to the bottom of the window frame whereupon, upon removing thc lower parting stripsection 42, the outer sash 36 may be swun inwardly as in the case of the inner sash as above stated.

It will be understood from the foregoing description that the window structure, according to applicants invention, may be comparatively simple and inexpensive, per mitting of the ready mani ulation of the sashes upon thc respective rames in which they are carried, to facilitate cleaning and repairs, and all without sacrifice of the area of transparent surfaces provided by the windows. Furthermore, particularly in vicw of the fact that the relatively thin frames 13 and 34 are provided, window structures of the form as commonly provided may be readily remodeled at comparatively little expense to present my improvements and without sacrlfice of transparent area.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. The combination of a window-frame, upper and lower frames movable up and down in said window-frame, guides on said window-frame for said upper and lower frames, window-sashes mounted in said upper and lower frames and movable relative thereto, and removable stops on said window-frame for said sashes for holding the latter against displacement in the frames in which they are mounted.
