BASEMENT WINDOW STRUCTURE Lyon D. Evans, Louisville, Ky., assignor to Reynolds Metals Company, Richmond, Va., a corporation of l Delaware Application March 11, 1953, Serial No. 341,708

1 Claim. (Cl. 189-66) The object of this invention is to provide a basement window combining frame and sash which will permit double sealing against the weather without overlapping of the sections on either the interior or exterior. The entire frame and sash may be made of extruded structural members. This inventive construction enables the window sash to be opened to a horizontal position of rest that is at a 90 angle relative to the frame, and held in this position by the weight of the sash acting on the window frame. The sash may easily be removed and replaced without disturbing the frame assembly or removing any part thereof. When the window is open, by moving outwardly the window sash to a desired position, two holding arms, which are arranged to slide in the frame, receive the weight of the sash through use of the fulerum principle. wardly on the top of the sash, that part of the sash touching the frame slides up until it is in Contact with a bearing face on each arm. The weight of the sash operating on a fulcruin principle, forces the rear edge of the sash against the frame, firmly holding it there. In this position, and by slightly tilting the sash upwardly, it is possible to raise the sash to any position on the frame, and upon releasing it have it held in place against the frame.

The invention will be described with reference to the accompanying drawings, in which Fig. l is a View in elevation showing the frame and sash in position;

Referring to the drawing, a substantially rectangular frame, having a pair of spaced-apart vertical extruded frame members 1 and a pair of spaced-apart horizontal extruded members 2 and 2x is constructed of a size to fit a cellar or basement window opening.

As shown in Figs. lO and 4a, the extruded member 1 is provided with a vertical exterior wall 3 adapted to engage the vertical exterior wall 4 of the basement opening. The vertical frame exterior wall 3 is preferably provided with a flange 5, which ange contacts the basement wall surface. The vertical frame member 2 is also provided with an interior wall 6. A vertical wall 7 is disposed intermediate integrally and perpendicularly to walls 3 and 6.

The interior wall 6, which is disposed inwardly toward the cellar, has a section 8 disposed in engagementwith the wall 4 of the basement cavity. The wall 6 is also provided with a vertical integral strip 9, which is spacedapart and parallel to frame wall 7. A set-back faceplate 10 is integral with, perpendicular to and set back relative to exterior wall 3. A strip 11 is integrally and perpendicnlarly united to the free extremity of face plate l? and disposed in spaced-apart but opposed relation to strip 9.

The vertical members 1 are solid integral units, since all the parts described above` are longitudinal and thus may be extruded from a die. Thus the members 1, as well as all other longitudinal structural members to be described hereinafter, may be made from metal, such as aluminum, by means of an extrusion die.

The vertical members 1 are identical but are assembled to the basement walls 4 so that both of the walls 3 are disposed outwardly away from the basement window cavity.

The detail structure of the horizontal frame members 2 is shown in Figs. 6, 1l and 12. Turning to Fig. 6, it will be seen that the top horizontal frame 2 is somewhat different from the bottom frame 2x.

The top horizontal frame member 2 is provided with a horizontal ledge 12, to which is perpendicularly and integrally attached a vertical exterior wall 13, preferably having a flange 14 adapted to contact the exterior surface of the basement wall 4. The interior edge of ledge 12 is provided with a longitudinal depending leg 15 disposed at a right angle to ledge 12. A` depending face-platel is integral with and perpendicular to ledge 12, and is disposed in set back relation to exterior wall 13.

The depending face-plate 16 is disposed in spaced apart relationship to the depending leg 15, and is of a shorter length than is said leg 15. i

The bottom horizontal frame member 2x is provided with a horizontal ledge 17 (Fig. 6), an interior upright wall 18, and an interior depending wall 19 having a ange 20, adapted to contact the basement wall 4. Wall 18 is integral with wall 19 and ledge 17, the two walls and ledge forming a T-shape structure. The exterior end of ledge 17 is preferably turned upward at an oblique angle to forni plate piece 21. An upright face-plate 22, of a shorter length than upright wall 13, is integral with ledge 17 and is spaced apart relative thereto.

As shown in Fig. 14 the horizontal frame members 2 extend beyond the vertical frame members 7 and are keyed into grooves or cut-outs disposed in said horizontal 3 frame members 2 to form a secured integrated frame unit.

Turning now to the sash (Figs. 7, 8 and 10), the sash unit is of a rectangular shape made from four identical angular structural members 23, disposed outwardly from the window panes 24. Each sash frame member 23 has a center plate 25, to which is integrally united an exterior plate 26 disposed outwardly at a right angle to plate 25. A second plate 27 is disposed in spaced apart relationship to plate 26 and on the same side of center plate 25. An angle plate 28 is integrally united to the interior end of plate 25 on the side opposed to plate 28, said plate 28 being provided with a flange 29 against which the window 24 rests.

As shown in Fig. 9, the sash is provided with a T-shaped separator piece 30, the T arms of which have a raised flange 31 against which the window pane 24 rests. A triangular layer of putty 32 is disposed against the window pane and the adjacent contacting structural members, thereby keeping the window pane 24 in place.

The sash is removably secured to the vertical frame members 2 (Figs. 4 and l0) by means of opposite fulcrum arms 33 adapted to support the weight of the sash against the member 2. A button 34, provided with a shank 35 is secured to each fulcrum arm 33 by co-action with a cylindrical separator 36 having a bore-hole. Each fulcrum arm and its button is secured to the center plate 25` by means of a headed pin 37, which pin may be provided with screw threads adapted to engage the bore-hole walls of said separator 36.

The button 34 slides vertically in the grooved channel formed by opposed spaced apart walls 9 and 11, relative to plate 7 which latter is spaced apart from said walls 9 and 11. Pin 37 is secured to the vertical sash wall center plates 25 at a point intermediate its ends. As shown in Fig. 6, the walls 9 and 11 are provided near their tops with curved cut-outs 33 of a diameter greater than that of buttons 34, thus providing for easy insertion or removal of said buttons 34 from confinement by strips or tracks 9 and 11, thereby facilitating the entire removal of the sash and the two fulcrum arms away from the frame.

As shown in Figs. 8 and l0 the exterior walls 26 of the closed sash lie against face- pieces 16 and 22 of the top and bottom horizontal frame members 2, and the vertical sash walls 26 lie against face-pieces 10 of the vertical members 1. Similarly in the closed sash, the short plates 27 engage the wall 15 of the top horizontal frame member and wall 18 of the bottom horizontal frame member, while` plates 27 disposed in the vertical sash members 23 (Fig. 10) engage the interior of wall 6.

The overall result is that the rectangular sash when in closed position engages the corresponding rectangular frame in a double spaced apart linear manner on each of the four rectangular sides, thereby sealing out the weather fromV the basement in a dual manner.

As shown in Figs. 4 and 4a the sash may be lifted upwardly by a handle 39 (Fig. l5) secured to T-shaped separator 30. The top of the sash is moved outwardly causing the part of the sash below pin 37 to move inwardly. The sash then may be caused to assume a horizontal position (Figs, 3 and 4). The sash then may be moved up or down the members 1 with the buttons 34 riding in the confining channels of the vertical members 1. In horizontal sash position the bottom sash wall 26 rests in weighted frictional contact with walls 10 of the vertical frame members, thereby preventing falling of the sash since the center of gravity of the horizontally extended sash tends to rotate it clockwise thereby forcing the edge of wall 26 to grippingly engage the frame walls 10.

The sash may be locked to the frame by means of an angular swing latch 40 riveted by rivet 41 to the top of top sash frame plate 25 (Figs. 11 and 12). 'I'he swing latchV 40 may be a single plate piece having a center section 42, a depending finger grasp 43, and upright lug 44. A cooperating lock pin 45 is secured to center plate 12 of the top horizontal frame member 2. In the closed position the lug 44 is disposed behind pin 45 (Fig. 11) so that the sash cannot be raised. In the open position, the finger grasp 43 is swung outwardly so that lug 44 is disposed to one side of pin 45, thereby permitting the sash to be raised.

This invention has been described by means of an illustrative embodiment but obviously it is of the broader scope as claimed herein.

Having described my invention, what I claim and desire to secure by Letters Patent is as follows:

A Casement window structure adapted for doubly sealing out the weather and made from linear extruded structural members comprising a frame having longitudinal substantially tubular and substantially rectangular extruded vertical members having channels therein, said channels being of a T-shaped configuration with the stem of the channel forming a slot in said substantially tubular member and forming a pair of spaced apart offset linear abutment and load bearing surfaces disposed on each side of each slot, said frame having horizontal top and bottom frame members, the top frame member being substantially Z-shaped and the bottom frame member being sub stantially T-shaped, each of said top and bottom frame members having a pair of offset spaced apart linear abutment non-loading bearing surfaces, a sash adapted to both slide and swing and provided with a pair of peripherally disposed vertical extruded members and a pair of peripherally disposed horizontal extruded members secured to said vertical members, said sash members having a pair of offset spaced apart linear abutment surfaces adapted to engage the corresponding pair of spaced apart abutment surfaces of said frame members, at least one swingable fulcrum arm pivoted to the sash and having a headed stud at one end adapted to slide in a confining manner in the slot formed between the walls of and` constituting the T-shaped channel of a co-acting vertical frame member.
