Referring now to the drawingsjin detail, and first to the typeof construction 'of a window frame for frame houses, 1 denotes the sillwhich slopes downwardly and out wardly, as conventional, and is provided at its upper side and for its full length with perspective of pulley stile in interlocked rela More speand useful features of construction and combinations of and the head of the side blind an inner outwardly-facingshoulder 2 and an outer outwardly-facing shoulder. The'sill is of thedouble horn type at'each inner horns & projecting beyond the the body portion of the sill with their outer faces coincidental withtheshoulder 3, and with the inner faces of the outer horns 5, the

latter pro ecting lateraliybeyond the horns t and having their upper races occupying lower plane Theopposite facesof-the body portion of the sill areparalleland in the under side of the sill are provided inwardly facing inner and outer shoulders 6 and 7 and downwardly-opening grooves 8 and 9.

Pulley stiles 10 abut against and are see cured to opposite ends of .thesill', having grooves llj conforming to and receiving the V i said pulley 1} stiles areconnected at or; near their upper .ends bythe head jamb I2, .junction with employed in frame respective ends of the sill, and

which j amb in conthe' pulley sill constitute a rigid. rectangular frame. Thepulley stiles. are provided with vertical grooves 13 c'ontaining the parting stops "14,

side with a groove lfi-receiving the upper end, the ends of stiles l0 and-the jamb is provided at its under,

parting stop l6,the'same engaging the upper ends of the, parting stops 14c. The outer edges of the pulley stiles 10 are provided withtaperedgrooves 17 and abutt ng against said edges and litting'down upon the $111 at the innerends of horns 4 are 'ver "ti'cal side blind stops vertical wedge tongues 19 snugly fitting the 18, said stops having grooves 17. Ahead blind stop QOfits against theouter edge of the head jamb and'bears at its oppositeends against and is secured to the side blind stopslS and is provided at its inner side with a horizontal wedge tongue 1 engaging a corresponding groove 22 in the outer edge ofthe head jamb 12. Vertical side casings 23 fitupon thesill "and against the side vertical tapered grooves 2st snuglyreceiving vertical wedge tongues 25 on tlie outer faces stops. Fitting upon the up per'ends of. the side casings, is ahead casing 26 provided at its lower edge witha' tapered groovel27 snugly receiving correspondingwedge' tongues 28 on the upper'ends blind stops and are provided with It will be'noted by of the side casings 23. The head casing is also provided in its inner face with a horizontal head casing 26, and is provided at its under side with a rabbet or groove 32 snugly fitting said head casing, and outward of the latter with a "water-drip groove 33 to serve as a water drip.

The pulley stiles 10 are provided in their outer faces with vertical grooves 34; receiving theadjacent edges of the ground pieces 35 forming the inner walls of the pulley. boxes, of which theouterwalls are constituted by the studs 36. The remaining features disclosed by Figures 1 and 2 are conventional and are simply identified by the following reference characters. A indicates building paper at the outer sides of the sheathing B V fastened to studs 36 and at the upper end of thecasing to the plates or studs E. C represents lathing and D plaster. F represents back bands and G, inside casing. H indicates inside stops and J the stool and K the apron. v

, Referring now to a window frame for use inmasonry houses, it will be noted that the sill37 has the shoulders 38 and 39 corresponding to shoulders 2 andy3,a nd that between I said shoulders tli'ebody portion of the sill is prolonged or extended as at 40, the outer edges of the extensions 7 7 being disposed in ward of the shoulder 3. of the body portion ofthe sill provide inner and'outer notches 41 and 42, the former of greater length. than the latter, and communieating with the inner ends of notches l l are grooves formedin the upper side of the body portion of the sill and having bottoms which taper from the upper surfaces of the sill adjacent shoul'ler 39to the opposite edge of the sill, these groovesreceiving the inner side walls or stiles fil of the pu ley boxes. The

pulley boxesconsist of'parallel spaced pulley stiles 51 and walls inner walls 53 and exterior walls 54, the walls 52 to 5 inclusive depending to a lower plane than wall or stile 51, which fits snugly in the groove 50. The inner wall 5 3 fits in notch 41 and wall 54 is stepped at its lower end so as to rest upon the sill coincidental with the shoulder 39 and to extend down into the notch 42 where it abuts against and'is secured to the wall 52, and said wall 54 is provided in itsinner face with a tapered groove 55 receiving-a corresponding wedge tongue 56.0n the outer edge of the pulley stile51, and secured tothe outer side or face of the wall 54, is a brick mold 57, reference to. Figures 5 and 7, that a vertical space is provided between the wall 54 andthe abutting side cas- The prolongations' tions with the opposingor inner ing 57bymaking the inner portion of wall 54- of increased thickness, this space being provided for the accommodation of waterproofbuilding paper and mortar seal. In

the respects mentioned, that is in the detail frame houses applies equally well to the framefor masonry houses.., For windows provided with a mullion, the latter consist-s of a vertical box 58 of which the outer wall 59 is provided .with vertical tapered grooves GO in its'inncr face receiving corresponding tongues 61 on the outer edges ofthe side walls of the box, and fastened to the outer face of the wall 59 is a casing 62 which matches the side and head casings and extends from the latter to the sill as customary. The jnxtaposed faces of the wall 59 and casing. .62, are channelled at 63 to provide an air space serving to prevent cupping or warping of said parts. v i

The grooves on the pulley stiles engaged by .the ends of the sill in the windowframe for frame buildings constitute dadoes to prevent air and water leakage at such points,

and, while not so shown, the head jamb in the wood construction also has dado connecfacesof the pulley stiles for the same reason. The grooves formed by and between the inner shoulder 2 of the sill and the parting stops of course receive the lower sash, not shown, and the spaces-betweenthe parting stops and the'outerblind stops the reception and operation of the outer sash, not shown, and the Various wedge-shaped tongue andv groove connections at every exposed joint constitute interlocks to prevent air, water anddust leakage, as well as impart to lllleWlIltlUW frame greater strength, rigidity and durability. The outer shoulder on the upper surface of thesill,-which is pitched to insure free drainage,-affords a water proof joint or abutment for a storm sash, not shown. The provision of thedouble horns provides for a connection therewith of the blind stops and the inner sides of the side casings whichis water proof ,and the sill has parallel upper and-lower faces to insure tight joints for the entire width of the jamb; The water drip grooves on the drip cap and sill are to prevent water from backing up, and the groove-8 in'the bottom of the sill is for the reception of the, underlying siding. v

As a whole to describe the description of the upper part of a window frame for provide the groovesfor the casing not only is thor- I easily assembled.

able construction, but it is also of economical construction as the parts can be readily and be thefir'st completely air-tight .orwatertight wood window frame, and it has gone into very extensive use.

From the above description, it will beapparent that I have produced a window frame embodying the features of advantage set forth as desirable inthe statement of the object of the invention, and which may be modified in minor particulars without departing from the spirit and scope of the appended claims.
