DOOR ANDiWINDOW FRAME Felix P. Blanchard, San Antonio, Tex. Application December 1, 1947, Serial No. 789,091

This invention relates to window frames, and more particularly to an improved window or door frame so constructed and arranged that it may be readily incorporated as a complete unit into the structure of a building during .the construction thereof, with a minimum amount of'labor and material expense.

' .It'is an object of this invention to provide an improved window frame of the kind to be more particularly described hereinafter, of suflficient building construction, and there assembled by securing the separate members together, they being formed to the desired shape and size before shipment.

A further object of this invention is to provide a frame of this kind,.having grooves or rabheted edges for the reception therein of the desired sheathing into the edge of the frame, thereby .obviating the requirement for the use of trim about the edge of the frame to provide the finished appearance thereof. g A still further object of this invention is to provide a window and door frame of this kind which may be readily assembled by..merely nailing the ends of the component parts thereof to the adjacent part whereby the frame may be assembled with unskilled labor, and the finished frame is such as toform a finished assembly when incorporated into the adjacent building structure without the use of added trim materials.

With theabove and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims. In the drawings,

Referring to the drawings, the numeral 25 designates generally a window frame which is formed of separate vsideand end members which maybe formed before the assembly thereofiproof a side jamb view of the side viding a type of packaged window frame. The

frame 25 is so constructed and arranged that the components thereof may be completely formed at the point of manufacture .and shipped in knocked-down form to the location of the :job where they may be readily assembled by merely securing theends of component frame members together. The assembly .is such that no skilled work is required and the frame is of sucha struc ture that there .is no need for .extra frame workv for supporting the wall structure about the window. l

extending stri 68 along the length thereof. The

strip ,88 is formed at an angle relative to the surfaces 64 and 65. The .strip 68 is adapted to be disposed horizontally relative to a building, While the surfaces 64 and 65 are adapted to .be inclined downwardly and outwardly of the wall on which the sill 2! is supported. The strip 68 terminates shortof the edge of the horizontal shelf :59, forming a shoulder 18 spaced outwardly from the inner longitudinal edge of the sill 21.

As shown in Figure 7 of the drawings, the shoulder 18 forms a stop for the screen 45 used as in Figure .5, interiorly of the frame with a casement window. The lower surface 65 of the sill 2.! is formed along its inner longitudinal edge with a rabbet or recess H within which the sheet rock of the inner wall may be engaged. A second rabbet or recess :12 is formed along the longitudinal inner lower edge of the body 62 and the upper edge of the recess H.

. The finishing strip 14 may be engaged par .tially within the rabbet l2 and partially overlying the sheet rock of the inner wall.

The upper surface .64 of the sill 21 is formed at its opposite ends with a substantially flat downwardly and outwardly inclined .surface 75 with which the lower end .of the side members 28 and 29 maybe abuttingly engaged. The flat surface follows generally the main cross sectional contour of the sill '21, having the forward portion thereof downwardly and outwardly inclined with a substantially horizontal inner surface 16 formed as a continuation thereof.

A notch H is formed at the opposite ends of the sill 21 for registry with the grooves 52 of the side frame members near the front edge. A notch 18 is formed at the opposite ends of the inner edge of the sill 21 for registry with the rabbets 54 of the side frame members, and a notch i9 is formed adjacent the notch 18 for registry with the rabbets 55. The rabbets 31, 55 and 79 form a peripheral recess about the frame 25, within which the trim material may be engaged when desired. The rabbets 36, 54 and TI form a larger recessabout the frame 25 outwardly of the recess formed by the rabbets described above, within which the adjacent edges of the inner surface of the wall may be engaged with the frame 25.

The grooves 3'4 and .52 form a peripheral groove about the fram 25 for engagement of the inner Surface of the wall. with the frame to. form a complete attached structure. As. the edges of'the wall adjacent the frame 25 terminate substantially within the frame members, the use of added trimming material is. not necessary, although it may be added by incorporation of the trim ma'- terial in the extreme inner peripheralgroove as described above. The notches at. the ends 'of the, head member and sill provide for the continuation of the recesses and grooves about the periphery of the frame.

In the use of double hung windows. in the frame 5,. it is necessary to provide means for supporting the counterbalance for the windows 80., Normally such windows are counterbalanced by a sashweight, not shown in the drawings, connected to the windows themselves, by a flexible member or cord 89. The side frame members 28 and 29 are formed thereof with an opening as 8I- extending therethrough from the inner face through the outer face... The openings 8.1- on opposite side frame members are substantially in alignment. through the. inner confronting faces of th side jamb adjacent. the upper ends members. As the side members 28 and 29* normally abut vertical supporting members as 82 in the assembly of theframe to a wall, the vertical members 8.2 must also be provided with an opening as .84 therethrough, in registry with the openings 8i.

A plate as 85 may besupported on the side of the member 82 opposite from the jamb member, for providing sufficient space for the attachment of the pulley members to be described hereinafter. The cord 88 for supporting the windows is trained overa pulley .86, rotatably supported within the opening 8| of the jamb members 28 and 29. For supporting the pulley 86, I have provided a tubular sleeve member 8! engageable in the opening 8|. The tubular memberB'I'may be rectangular in cross section and is formed with a peripheral right .angularly disposed flange 88 about one end thereof.

Tangs as .89 may be struck from the body of the tube .8! along the vertical sides thereof for penetrating engagement within the frame member 28 for holding the tube 81 against sliding in the opening 8|. A series of vertical barbs as :98 are fixed to or formed on the upper and lower flat surfaces of the tube 81. The barbs 90 are directed inwardly and upwardly relative to the lamb member v29 for penetrating the jamb member at the upper and lower ends of the tube. The tangs 89 and the barbs 90 rigidly secure the tube 81 within the opening 81 of the side member 28.

An axle as 9| the tube8'i and the on this axle. The

is supported transversely of pulley 86 is rotatably mounted cord 88 is trained upwardly from the windows 6 0 and over the pulley 86 where it may then descend to the-sashweight.

As shown in Figure 4, where the walls are of a. total thickness greater than the diameter of the pulley 86., more than one of such pulleys must be used. For this purpose the plate as is formed with an opening 92 therein, in registry with the openings. 84 and 8|. A second pulley 86 is carried by a reversed tubular member 81 in confronting relation to the first tubular member, for carrying the cord '80 across the width of the wall. While the pulley 88 is of a diameter greater than the thickness of one of the side members as 28, when the frame 25 is incorporated within a building and fastened to vertical members of the. wall, a plurality of pulleys and their supporting members .81 must be used.

The frame members 26, 21, 28, and 29, while described in their assembled relation, are placed in this relation by simply nailing the vertical side members 28 and 29 to the horizontal end members 26 and 21. The vertical members are correctly positioned relative to the horizontal members by the snug engagement of the vertical members against the shoulder 41 of the head lamb member and the shoulder 94 on the sill member. The shoulder 94 is formed by the lowering or smoothing-of the outerend of the sill member to provide the surface 15 above described.

In Figures. 11 to 20 there is shown members of a. door frame formed in a manner similar to the window frame described above. In Figures 11 and 12 there is shown a head jamb member 108, formed with a fiat lower surface [81. The head iambmember I is formed with a groove I 82 extending along the length thereof on the upper surface, spaced inwardly from the outer edge thereof. The head jamb member I80 is adapted particularly for use with an outside door. The outer wall covering of ship lap is adapted registry with the grooves of said side jambs, and means securing each of said jamb members to an adjacent jamb member.
