13 claims. (CI. toi- 11) This invention relates to window frames. It will be described as incorporated in a window frame constructed of wood or similar material and of the type extensively used in the construction of dwelling houses. p

An object of this invention is the provision of a window frame which resists the leakage of air and moisture between the adjacent members o the frame.v

Another object is the provision of such a frame which includes elements so formed and inter tted that the parts are readily retained in place while they are being secured together.

In the accompanying drawing, Y Y y Fig. 1 is a perspective sectional view partly broken away and taken substantially on the vertical axis ot a window frame incorporating my invention; ,A u

Fig. 2 is an enlarged fragmentary section of a portion of the head jamb and associated parts;

Fig. 3 is a vertical section through a window Yframe head section illustrating the prior construction as contrasted with my improved construction; K

The frame shown in Fig. 1 comprises head and side jambs 5 and 6 respectively having grooves 7 and 8 therein in which are tted window sash stops 9 and 11. Adjacent the outer edge of the jambs are provided semi-cylindrical grooves 12 and 13 in which are iitted the beads 14 and 15 on the blind stops 16 and 17 respectively. ,The blind stops 16 and 17 are of the same shape and as the stop 16 is shown in enlarged section in Fig. 2, it will be described more in detail.

The blind stop 16 includes a body portion 1S which is interposed between the cuter edge 19 or the head jamb 5 and the inner side or face 21 of the head casing 22, which casing lies in a plane at right angles to the plane in which the head jamb 5 is positioned. The lower end 23 of the stop 16 extends a substantial distance below the lower edge 24 of the casing 22 so as to providea means against which blinds, a screen or a storm sash may be positioned. The lower end 23 of the stop 16 extends inwardly'a short distance under the lower face 25 of the jamb 5 and is adapted to have its inner face 26 engaged by a window sash or the like. As best shown in Fig. 2, it may be seen that the bead 14 is offset 0 inwardly from the body portion 18 of the stop 16 a sucient distance to make room for a substantially rigid bead or tongue 27 on the jam 5 between the groove 12 and the outer edge 19. When the

parts

5 and 16 are snugly tted together asshown in Fig. 2 they may be secured together as by-nails 28 without danger of relative slippage or movement between the jambV and the stop. g

In order that the casing 22 may be accurately vpositioned andV held in position while itis being nailed to the jamb 5 through the stop 16, I have provided a tongue or bead 29 which extends into a recess Elvin the face 21 of the casing 22. The groove 31 preferably has a beveled edge 33 engaging with a cooperating beveled edge 34 on the f bead 29. By the use of sucha beveled tting, it 'is possible to make a substantially moisture proof joint, particularly so if white lead yor the like is applied to the partsY as theyare being tted together. A vdrip -cap 36 is positioned on the upper edge of the head casing 2,2 and pref,- erably secured thereto as by nails 37.v The lower ends of the side casing 39 and the side jamb and side blind stop are positioned on and suitably secured to the window sill 41.

By a comparison of Fig. 2 with Fig. 3 it will be seen that my use of the specific stop construc- .tion having interlocking engagement with the jamb and the casing not only insures a more accurate assembly and permanent interlocking entogether as by nails43, but no straight line joints such. as illustrated at 45 and 46 inFig; 3 are present in Fig; 2, the various engaging surfaces are irregular `being broken by the grooves and -dow-and the other side 34 beveledis this:

When the sides of a bead and groove are straight, the members can Ybe pulled apart as far,

vas the 'depth of the bead without opening up any air passage. If both sides of the beadand groove are beveled, any pulling apart of the members opens up an air passage. On theother hand the vadvantage `of having the sides beveledis that they center themselves and are more easily assembled and a. tighter joint can initially be made 1 on account of the wedgng action. By making one side straight and the other beveled, I retain the advantages of both types and also avoid the disadvantages of both. Y

Thus the beveled side 34 of the bead 29 makes for an easy assemblyand initially wedges the bead into a rm engagement withthe groove especially on the opposite or straight side. If the casing should draw away fromthe stop, there would ordinarily bevno tendency toward ar@il gagement o1" the'parts when they are secured relative movement in a direction parallel to the window and if there were, it would be checked by nail 43. Thus the straight side of bead would continue to engage the straight side of the groove with the result that no passage would be opened up. There would however be a slot opened up across the beveled side and across the bottom of the groove. I prefer to have the straight side come on the side nearest the weather, so that there is less danger of water working into the slot which would thus be opened up, because the water would not be able to pass the engagement between the straight side of the bead and the straight side of the groove. A

In those instances where the blind stop is rabbeted into the jamb but is not interposed between the jamb and the casing, whereby the inside face of the casing directlycontacts the outer edge of the jamb, or frame member, the bead 29 would be formed on the edge of the jamb.

The

nails

28 and 43 are not relied upon to hold the stop against the edge of the jamb, because that function is performed by the interlocking bead- 14 and groove 12. The nails however do serve the function of preventing relative movement of the stop and jamb in` a direction parallel with the window. This is a shearing strain pull upon the nails rather than a pulling strain, and therefore the nails are much better able to continue successfully to perform this function.

Even apart from the foregoing function of the nails, the two beads 29 and 14 cooperate to maintain a tight seal of the blind stop against the jamb. The seal afforded by the groove 12 and thetongue 14 is one which resists relative movement of the parts transversely of the window but not in a direction parallel with the plane of the window. But movement of the blind stop away from the jamb in a direction parallel with the plane of the window is precluded by the tongue 29 which enters the groove 31 in the casing.

Y It will be understood by those skillled in the art that although I have shown a specific embodiment of my invention, it is susceptible of various forms and modifications without departing from the principle thereof as more particularl'y set forth in the appended claims. In the absence of other recognized generic term,I have used the'term jamb in the claims in the broader sense of including both the side jamb and the so-called head jamb.

I claim as my invention:
