This invention relates to buildings and particularly that portion of wooden structures adjacent to the glazed window sashes thereof, and the primary object is to provide a window frame .5 which constitutes an integral part of the building framework and which forms a weather and air tight juncture with the wall proper.

One of the important aims of the present invention is the provision of a window frame that is made of relatively heavy planks and which may be lore-fabricated and delivered directly to the job where it is assembled by the workmen as the framework of the building is erected so that no additional parts become necessary when handling the window sash.

This invention has for an even further object the provision of a window frame made of specially formed planks, each of which is arranged to constitute an element of the building framework and to be rigid enough to remain in an accurate place so that when the window sashes are installed, no blocking or time-consuming manipulation is required.

A yet further object of the invention is to provide a window sash frame for buildings, the parts of which not only form an integral portion of the building framework, but are so interlocked as to establish a completely air tight assembly, independent of either the outside or inside casing and trim.

Another important object of this invention is to provide specially formed framework for buildings with which doors or window sashes may be directly and operatively associated and which is made to establish a tight connection with the surrounding wall.

Further objects of this invention are to provide a window frame that will reduce the labor cost of installing; that will permit the contractor to purchase the complete window frame in a knocked-down condition but ready for assembly; that will permit windows to be installed at any time during the construction of the building; that produces a more rigid frame, making setting easier and more accurate; and that elim- Fig. 2 is an inside fragmentary condensed elevational view of the window frame installed.

Fig. 12 is a condensed fragmentary elevational 25 view of a building framework having door frame parts made in accordance with the modified form of the invention associated therewit- The framework it of buildings with which the Window frame embodying this invention is adapted to be associated, includes the conventional, vertical studding I2 and the horizontally disposed plates it that are usually lumber in the nature of tWo-by-fours and upon the outer faces of which is positioned sheeting It, over which is 5 placed building paper it and siding or other surfacing substance 20. The inner side of building framework it) has lathe 22 and plaster 24 thereon, and during completion of the building, the hereinafter described trim combines with- 40 members l6, I8 and 28 on the outside of the building and with

members

22 and 24 on the inside of the building to establish the desired appearance.

Since this invention is directed only tothe 45 window frame, it will be understood by those skilled in the art that the glazed window sashes 26 are operably mounted, whether through weights, springs, hinges or other equipment. The illustrated embodiment of the invention is "5 0 devoid of any example of means for movably mounting sashes 26.

The component parts of the window frame per se are made of heavy planks formed in a special manner and milled to interlock at the joints so that when the carpenter installs the component parts of the frame, only the parts supplied in the kit by the lumber yard, are necessary.

Each window frame comprises a jamb plank 28, the preferred form of which is sectional to present a main section 30 and a pair of completing sections 32. Main section 28 is wider than the two-by-fours from which studding and plates l2 and 14 respectively are made, and since the hereinafter mentioned elements are not needed on completing sections 32, the width of the latter may be the same as the remaining parts of the building framework.

The joint between section 30 and sections 32 is preferably in the nature of one having horizontal shoulders 34 so that part of the weight of upper plate [4 may be borne by this jamb plank.

In the illustrated embodiment of the invention a mullion type window has been shown, and Where such a window frame is used, mullion plank 36 forms a part of the structure. Head planks 38 equal in width to main section of jamb planks 28 interconnect the latter, or in the case of the mullion type shown, join together mullion plank 36 and jamb planks 28 so as to form the top edge of the opening wherein sashes 26 are disposed. The lower edge of this said opening is bounded by sill plate 40, the cross sectional contour of which is as illustrated in Fig. 5. A bead 42 projects outwardly from the normally lower face of sill plate 46 at the bottom of notch 44 which receives sill plank 46.

The upper face of sill plank 46 has a groove 48 created therein which extends its entire length and bead 42 enters groove 48 when elements and 46 are in the operative position. Sill plate 46 is further rabbeted to present a longitudinal groove 56 at one corner thereof which receives lathe and

plaster

22 and 24 respectively. 40 Another longitudinal groove 62 formed in sill plate 4!) is for the reception of a marginal edge .of siding 20 and the upper inclined face of plate 46 should have shoulder 54 formed thereon 'in the same plane as sill table 56.

When mullion plank 36 is not used to present a pair of openings, sill plate 40 extends completely across theopem'ng to be glazed, but where a mullion window is to be created in the structure, mullion plank 36 extends through sill plate 40 and head plank 3a to be joined with members as and 46, as seen in Figs. 1, 2 and 8. Any additional blocking necessary to rigidly secure the parts of the window frame to the framework of the building may be introduced and where the mullion plank is employed,

vertical blocks

60 and 62 respectively should be interposed to prevent sagging of upper plate 14 when weight is carried thereby, particularly directly over the openings formed by the window frame. 60' Central section 30 of jamb planks 28 have a plurality of longitudinally extending tongues 64 integral with one edge thereof, which edge is the one normally toward the outside of the building. The other longitudinal edge of jamb plank 30 is rabbeted so that a longitudinal groove 61 is formed for the reception of the ends of lathe 22 over which is spread a layer of plaster 24.

'I-Iead planks 38 likewise have longitudinally 0 extending tongues 66 integral with the normally inner edges thereof, while the opposite longitudinal edges are rabbeted to present groove 68, which serves as regards lathe and plaster Hand 24 respectively, as does groove 61 of jamb plank 30. u The inner faces of jamb planks 30 and head planks 38 are grooved to receive and operably maintain parting stops 16 in position. These par-ting stops may be glued, nailed, or otherwise fastened when the parts of the window frame is finished by applying grooved molding 12 directly to tongues 64 of jamb plank 3i) and directly to tongues 66 of head plank 38. This molding extends inwardly over the opening outlined by

planks

30 and 38 and combine with parting stop 10 in forming a most satisfactory slide-way for the outer window sash 26.

The line of juncture between molding strips 12 and sheeting I6 is approximately midway between the sides of the respective

underlying planks

36 and 38, and this joint is in turn covered by finishing strip 74 which extends along the two sides and top of the window frame. The drip cap 76 may be mounted upon the finishing strip I4 along the top of the window frame.

The inside of the window frame is finished through the use of a conventional trim plate 78 that is secured directly to the inner edges of head plank 38 and jamb plank 36. The width of this plate 18 is great enough to overlap the line of connection between

members

30 and 38 and the

other elements

22 and 24 of the building, and a molding 80 that cooperates with parting stops 10 in producing a slide-Way for inner sash 26 overlaps the joint between plate 18 and the inner surfaces of

planks

30 and 38.

Reference to Figs. 3 and 4 will indicate the manner in which the relatively wide jamb and

head planks

30 and 38 respectively, cooperate with the remaining parts just described, to establish a tight head and jamb independent of the casing and trim, that will not permit the passage of air as is the case where pro-formed window frames are set into place and blocked between studding of the building framework.

An extremely narrow mullion is permitted when window frames embodying this invention are introduced into the building walls. The preferred manner of building the mullion is shown in Fig, 6, where mullion plank 36 is grooved along the opposite sides thereof to receive parting stops 10 which are of the same nature and form as those introduced into the grooved formed in the

aforesaid members

30 and 38. Molding 80 extends upwardly along the inner faces of mullion plank 36 and channel member 82 secured to the outside edge of mullion plank 36 combines with parting stops 76 and said molding 8! in establishing slide-ways for the two sashes 26.

Where a wider mullion is desirable, the structure is as shown in Fig. 7. This illustrated embodiment of the invention is shown to indicate the manner in which a mullion type window may have a wider mullion for the-purpose of accommodating the various kinds of sash-operating mechanism that are now on the market.

Mullion planks have longitudinal, integral tongues 92 along the outer sides thereof to receive and hold molding strips 94 between which a filler plank 96 is'secured. Finishing plate 98 (while not necessary to create an air tight structure) is shown to indicate a manner of applying trim which overlaps the joint between elements 94 and 96. The inner side of this wider mullion has a plate 99 that fits into opposed grooves 9| in planks 90 to bridge the space therebetween. An ordinary finishing plate I60 cooperates with molding 86 in furnishing a'finish.

Because of the interlocking relation of

sections

36 and 32 of jamb plank 28, head plank 38, mullion plank 36, sill plank 46, sill plate 40, sill table 58, molding I2 and parting stops 'I0these elements together with member 50 should be pre-formed and packaged for delivery directly to the job. The length of sections 32 may vary because of the distance between plates Id of the building framework I0. These sections 32 may be somewhat longer than necessary, for it is not fatal to the effectiveness of this rigid window frame structure to have the carpenter cut the ends of sections 32 which abut plates I4 so that a tight fit is insured.

The lower end of mullion plank is slightly reduced in width so that the tongue 31 may extend through notch 4H formed inwardly from the inner edge of sill plate 40. The shoulders created by the production of tongue 31 rest upon the upper face of sill plate 40, while the squared end of mullion plank 36 engages a notch 47 in sill plank 46.

With these aforesaid parts supplied, it is easy for the cabinet maker to finish the Window frame both inside and out by using stock materials from which to form trim plates I8, molding 80, finishing strip M, and finishing plates 98 and I00. The conventional depending apron 84 may also be used on the inside of the window frame immediately below sill table 56.

The modified form of the invention illustrated in Fig. 8, discloses the manner in which jamb planks IEiI terminate at the member I02 which is set between studding I2. Head planks I04 engage jamb planks IOI and mullion plank I as before set down, and sill plate I08 is identical to the one employed in the preferred embodiment.

One skilled in the art will readily recognize that the concepts of this invention might be embodied in door frame structure, and one illustrated form of door frame, comprising parts formed as contemplated, is shown in Figs. 9, 10 and 11.

In this instance, plate I20 is supported by studding I22 in the normal manner. The head plank I24 is wider than plate and studding I20 and IE2 respectively, and extends outwardly to each side thereof to present a portion wherein notch I26 is provided.

As is illustrated in Figs. 3 and 4, the studding has a covering on the inner side, which is made up of lathe and plaster I28 and I30 respectively, while the outer covering constitutes the conventional sheeting I32. The thickness of the inner and outer covering is the same as the depth of notches I26 so that the outer longitudinal edges of head plank I22 lie in the same plane as the outer faces of these coverings. An air tight joint is thereby established, which, while helped by trim plate I34 and finishing strip I36, is not ineffective without them. The drip cap I38 overlies strip I33 and siding I40 is usually a part of the structure.

The inner face of head plank I24 has a groove M2 therein to receive a relatively wide parting strip I44 against which main door Hi0 and screen door I48 engage to limit their movement when such doors are hung on the frame. J amb planks I50 along each side of the opening wherein door I46 is to be hung, is of the same nature as head plank I24 in that it has notches I52 to receive a marginal portion of the inner covering comprising lathes I28 and plaster I30, and the marginal portion of sheeting I32. A dividing strip R54 is pressed into groove I50 which, like groove I42, is along the inner face of lamb plank I50.

When installing jamb planks I50 in the manner illustrated in Fig. 9, the main sections thereof are disposed along each side of the opening wherein door M6 is to be placed. End sections I58 are joined to the opposite ends of the main sections to completely fill the distance between upper plate I20 and the lower plate, not here shown. These upper sections I58 combine with main sections I50 in establishing a rigid support in the nature of one of the stu-ddings I22, and when jamb planks I50 are placed in the framework of the building, to reach from plate to plate a connecting member I60 having a width the same as plate and studding I20 and I22 respec tively, is employed with an additional short plate I62. The blocks I64 are conventional and may be supplied where desired.

In the form of the invention shown in Fig. 12, jamb planks I'I0 are of the same character with respect to width and grooving, as jamb planks I50. I-Iead plank I12 in this form is likewise of the same character as head plank I24. In this instance, jamb planks I10 do not extend to upper plate I20 but terminate against a short plate I'M Which joins studding I22 and which is supplemented by a short plate I76.

The nature of the door. and window frame elements, with respect to their Widths, groovings and relation with inner and outer covering and remaining parts of the building framework, is the same in the door frame as for the window frame installation. Both the door and window frame serves as a support at an integral part of the building framework and permits the establishment of an air tight joint around the window or door frame which needs no calking, covering or other form of weatherproofing.

The parts of a window frame and a door frame, made in accordance with the broad concepts of the present invention, as well as the manner of combining said parts with the framework of a building, have been made clear during the course of the foregoing description, and since structures of a type other than that disclosed might be made without departing from the spirit of the invention, it is desired to be limited only by the scope of the appended claims.
