' Theinvention forming the subject matter of this application relates .to window frame construction of the usualsliding sash type. i The main object of the invention is to provide a weather proof Window frame constructed so as tobe readily adapted for use with different forms of building constructionsuch as brick veneer, shingles, stucco, orj I I j 1 Figure {1' 1s a fragmentary spective of'thewindow sill,

'ticular form of joint between the lower ends masonry walls, drop ,or lap'siding. Another, object of the invention is to proprevent' air and moisture seeping from the outside of thebuilding to the inside thereof, and having relatively few parts interchangeabletoadapt the frames for useJin various types of building construction.

, A further object of theinvention isto pro- 7 vide a window' frame construction in which the jambs arerconnected to the sill so as to eliminate the water trap commonly formed the ends of the jambs and the ,partingstrip,

in the frames heretofore in general use.

Still another object of the invention 1s to construct the sill so as to recelve a continu- .ous wedge; member atits' bottom to eliminate the-use of loose wedges on the job, and-to ensure that the sill remains in position under the impact of blows resulting from the 'constant raising and loweringfof' the window sashes. f p

Another object of the invention is to provide a window frame construction in which the outside casing and jambs are connected by a tongueiand groove joint covered by a blind stop which takes the place of theordinary outside casing projection, used toform one side of the groove in which the outside sides in .an improved construction between the sill of the frame and the window stool: whereby weather, is prevented fromseepingv through the frame from the outside of the sill to theinner walls of the building.v

' Other objects of the invention will become apparent as the detailed'description thereof ll c'Oc'eeds.

In the drawings: A W e F lgure 1 1s afragmentary perspective view clearness, of disclosure;

showing the par of the jambs and the sills; a

' Figure '5 is a fragmentary vertical transverse section through the head of" the window frame and the trim connected thereto, and illustrating a modification frame construction shown in- Figure 1; Flgure dis a horizontal section taken exploded perof the window through an'intermediatemullion of a multi-' ple window frame, constructed inthe same" manner as that generally disclosed in Figure 5;and

Figure 7 is a vertical transverse section 3 through a windowlsill constructed in accordance'with the present invention;

- As'jshown in Figures '1 to (at of the drawings, the window frame comprises a pair of jar'nbs 1 and 2' (seeFigure-4n) ,-connected at their lower ends to a sill '3, and at their upperends to ahead 4. 1 The sill 3 is machined near its inner edge toform a downwardly [and outwardly beveled shoulder 5 which is adapted to contact {with'the correspondingly I beveled bottom rail of the insidesash when the latter isflowered in closing position againstthe sill 3; The shoulder 5 intersects the plane face 6 of the sill; andthis plane face continues to a second shoulder? formed by arabbet 8, terminating at the round cor- ;nered outer edge 9 ofthesill.

The uppe'rnarrow face 10 of. the sill im-' mediately back of the beveled shoulder 5 is provided with aigroove'll to receive a strip 12 of brass or other suitable material which projects from the upper face 10' into a groove outof a singlepiece of fmaterialr'abbeted 13 formed in the lower face ofa rabbet 14: i

iwith which the bottom face of the window stool 15 ,is provided. From Figure-.1 of the drawings, it. is evident that the vertical face of the. rabbet 14 forms a shoulder seating against the inner face of the sill 4. A packing strip 16 nailed against the inner vertical face of the sill 4 below the stool 15 serves to receive the apron 17 forming a trim finish against the plaster board or other suitable finishing material 18 of the building construction in which the frame is used.

The outside of the sill 4 is machined to form an inclined rabbet 19 adapted to receive a wedge shaped strip 20 extending throughout the length of the sill, and seated upon a 1 and down in their guide. grooves in the side jambs.

The wall-in which the frame is mounted is shown as formed by jan outerlayer of sheathing 22 covered by siding 23. The lowor face of the sill 4,,is provided with a groove 24adapted to receivethe upper edge of the siding .23 and forms therewith. a weather proof joint to prevent air and moisture leaking into the inside of the building from the outside thereof. Thesill has its outer edges rounded off to prevent slivering or denting and the lower face of the sill nearthe outer ed e thereofis provided with a weather drip 25. It will be apparent that the Slll construction at the lower facethereof pro- 6 groove vides a perfectly. weather tight and solid joint between the sill itself and the wall in which the frame is set. r

7 Referring to Figure 4, attention 15; directed to the fact that the outer edges of the

window jambs

1 and 2 terminate a short distance from the shoulder 7 on the sill 4, (see Figure 2). The lower end of the jamb 1 is rabbeted on its front face to form a'tongue 26 fitting tightly into the dado 27 formed in the sill 4. The shoulder 28 -formed by this rabbet fits, as a lip, closely againstthe upper face 'of the sill 4.

In the ordinary window frame construction, the dado 27 is made as wide as the jamb is thick, and forms a well having one edge directly open to the weather, with the face of the jamb serving as a means for conducting rain, snow and moisture directly to this edge. This poor construction is usually aggravated by the parting bead groove 30 extending to thebottom of the sill dado, and

7 not being filled by anything, since the parting head is always stopped against the'upper face of the sill. In this invention, the window sill dado is completely filled throughout its length, and theshoulder 28 prevents direct access of moisture thereto.

The parting bead groove 30 is less in depth 4 than the shoulder 28, so thatthe bottom of groove 30 terminates against the upper face of sill 4 and allows part of shoulder 28 to remain as a protection for the dado joint between the jamb and sill. It will be apparent that this construction completely eliminates the. water trap formed at the sill end of the parting bead in a window frame of ordinary construction.

The joint between the sill 4 and jamb 2 is exactly the same as the joint between the sill-andjamb 1. The same joint is used between the sill and the jambs of any intermediate sash box mullion of a multiple sash frame.

The stile 31 of the outside casing has its lower end butted against the horn 32 of the sill 4, and this end is rabbeted to fit over the beveled weather drip shoulder-7 and permit theinner face of stile 31 to contact. with the edge of jamb 1. As shown clearly in Figure 2, the edge of the jamb 1 has a head 33 seated in afigroove 34 formed inthe back face of the stile 31. V

The bead 33 is not centered on the edge of the jamb 31; it .is located toward the rear face of the jamb so that it extends clear down to the bottom of the dado 27 in the sill 4. Preferably the edge of the bead 33 is flush with the bottom of the shoulder 7 so that when thelower end of stile'31 is rabbeted, I

the edge of the head will fit against the stile throughout its length. The sill dado is of the same depth throughout its length; and, preferably, has its bottom flush with the upper the shoulder 7. and the rounded edge 9,

thereby eliminating any weather trap which would occur if the dado were of greater depth.

The upper end of the stile 31 has atongue 1 35 formed thereon to fit into a groove 36 formed in the lower edge of the head 36 of the outside casing. This casing head 36 extends along the head 4 from one jamb to another of the window frame and the groove 36 then constitutes a drip groove to prevent water or moisture creeping toward the head 4.

' The head 4 is of the same width as the

jambs

1 and 2; and has one edge provided with a' groove, while the other edge has a tongue 38 formed thereon to fit in a groove 39in the rear face of the casing head 36. The upper edge of the head 36 is squared to seat in a rabbet 40 formed in the lower face of a cap moulding 41, having the usual drip groove 42. The upper face of the moulding 41 is downwardly beveled to shed the weather, and a rib or flange 43 is formed thereon to provide a seat for the lower edge of siding 44 or other finish for the outer wall of the building.

The window jamb and head construction vary somewhat with the character of the wall in which the window is to be arranged.

In order to use the same "style of outside casing,,jambs, sill and head Where sheathing is interposed between the Figure 2) has a strip 46 secured to the inner edge thereof. This strip 46 is provided with a tongue 47- fitted into agroove 48 formed or not, as desired.

on the inner edge of the jamb 1; The strip 46 is'also provided with a groove 49 adapted to receivena tongue similar to tongue 47 on a strip similar to'strip 46- in cases where it is desired or .necessary to use wider a-mbs;

which may be widened merely; by securing several edges of strips 46 to the edges of the window jambs. These strips 46 may be continued down past. the sill to form a backing for the apron 17 The strip 16 can be used corresponding construction will, of course, be necessaryffor the head of this type a in cross section to the strip 46 must be nailed or otherwise secured to the inside edgeof the .head 4, which has its saidinside edge 811111131? ly grooved to receive the tongue formed on .said strip. The captrim 53 may have its lower edgeprovidedwith a tongue 54 adapted to fit into'the groove 55 of the strip 52 or I to fitintothe groove 56 formed on t-heinner head. A bead 58 may be suitably secured in.

Attention is directed to thefact that the groove 30 is not sufiiciently deep tohave the bottom thereof aligned with the faceofthe tongue 26 at the lower endof the j amb.

Of course, it will be understood that the sameconstruction of designed to preventwater blind stop extendsalong the head of theframe and along the j amb 2 at the other side of the Window. I. V a a In the formshown in Figures 5 and 6 of the drawings,the

strips

46 and 52 are omitted,

because in thisacase the outside sheathingis omittedand thesidingis naileddirectly to the studding. In order to use the same thickness of sash inthis modification of frameall that is necessary is to use a sash bead 63 of parent that the same outside casing and the 3 same =jamhs, head and sill of. the window frame may be used. All that is necessary to compensate for the omission of the'sheathing, i

45 and-the strips 46 an'd52 is to provide sash heading and window sill trim somewhatnarrower to compensate for differences in width cfthe jambsii v;From the.,-foregoing description, it will. be.

apparent'that I have provided a substantially. weather be readilyadapted for use in walls of different thicknesses. It will-also be apparent that 1 of window frame; that is, a strip 52 similar I proof window frame which may have provided a window frame construction to the headcasingor through thejambs or sill to thein sideof the-walh orto .the inside of the building of which the wall forms a part. The

tongue and groove construction is such' as 'to cause eachxmemberoffthe frame to interlock with the other members so that there is only one'wayin which the frame can be setup exactly square. Ther'eis noopen joint befrom feeding. back tween the side and head casings'of the present frame, since this joint is made weather proof by the tight tongue andigrooveconstruction.

The rabbeting of the lower. ends of 'the jambsto-eliminate' the ordinary water trap formedby the partingbeadgroove is one of. themost important features of the invention, 1,; 'becausefit prevents the formationof a well'or ordinarily causes trap for ,thewater. which the l at this point and allows the a p W t0 b drawn into the house by heat and capillary attraction. o

The metallic weather strip between the 1 dow sill-andthe stool forms another important element in the prevention of weather leaking through the frame into the interior of the building) The rabbeting of the outside 1 12 0 casing at the lower ends forms a water tight joint with the outside" weather drip shoulder of the sill.

. Thisshou'lder also forms a convenient stop against which the lower end of a V the outside casing may bepositioned and nailed.

The continuous wedge is an essential part of a window frame of this type, because the sill thereof is designed to have-the slope about three times, as great as that which is normally employed in v ordinary window frame con-,

V the annexed claims.

1,29 window stool rabbeted to contact with the 3 having a rabbet formed in its lower face between the sides thereof, and a continuous wedge shaped member'seated in said rabbet ing its lower edge grooved throughout its "*9 having transverse dados formed therein, a

struction. Moreover, this wedge forms a solid base to receive the impact of the sashes as they are lowered in the frame, and thereby prevents separation of the sill from the lower ends of the jambs.

While I have described my, invention as embodied in concrete form and as operating in a specific manner in accordance with the provisions of the patent statutes, it should be understood that Ido not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing from the spirit of my invention, the scope of which is set forth in What I claim is:

' 1. In a window frame, a sill having an upstanding portion formed on its upper face and extending along the rear side thereof, a

edge of and seat on said portion, said stool and portion being provided with registeringgrooves, and a tongue seated in said grooves.

2. Ina window frame construction, a sill to give the sill a predetermined slopewhen the lower face of the wedge is seated on a horizontal support. 1 V

3. In a window frame construction, a sill, a pair of jambs and a head, and outside cas V ings tongued andgrooved to said jarnbs and head, the head of said outside casings havlength to receive tongues on the upper ends of the stiles of said casings and to form a water drip groove betweensaid ends.

edge and 4.-In awindow frame construction, a sill pair of jambs having tongues at their lower ends filling said dados and having shoulders butted against'the upper face of said sill, eachljamb having a tongue along. its outside centered in alignment with the tongues on said-ends, outside casings ooved to receive the tongues'on saidjam s, and 1 blind stops secured-to said jambsl and the edges of said casings.
