WINDOW FRAME isa'aseriai No'. 355,865; latent No. 1,790,428. Divided and this appucation filed December 13, 1930;;7Seria1 No'. 502,216.
proof and can be matedV at the point of as-V sembly, irrespective of expansion and contraction of the wood composingthe same. In the window frame art the connection betweenVV the blind stop and the pulley stile respectively was, vat first, of flat formation. In the practicalart this was called a fsurfaced four sides connection. For windproofing and weatherproofing the connection relied entirely upon the tightness of theconnection between the lflat contacting surfaces of the blind stop and pulley stile respectively.
The practical art later utilized a tongue and groove connection between these parts in an eort to increase the weatherproof and moistureproof qualities of the connection'. These tongue and groove connections com.- prised a square bottom groove and a round nose tongue or a square tongue. In the industry today the sections constituting the window frames are required to be shipped in knock-down condition to the point of assembly. Thus they may be manufactured in the State of Washington and vshipped in knocked-down condition to say the State of New York. Due to the expansion and contractionV a tight interlitting connection be# tween the tongue and walls of the groove could not be obtained because the grooves necessarily were required to be of considerably wider dimensions than the tongues. Y
Such connections, therefore, would afford `merely an air baffle but their waterproofing characteristics proved to bel negligible. As
the result, in the practical art, it has been my experience that manufacturers considered the disadvantages attending the use of the square groove and ktongue connection to outweigh their advantages and as the result, up until i I the advent of this invention, most practical workers in the art preferred the original con struction wherein the faces between the blind stops and pulley stiles respectively were flat. '5-
lMy invention is based upon thevco'nception thata blind stop` may be provided .with oppositely beveled walls of taperediformation acting in cooperation with complemental tapered tongues, which'tongues are preferably not-as great in length as the groovesfoll the purpose hereinafter stated. F o
I have found that this construction actually seals the connection against weather because of the constantly contacting faces -of the tapered tongues with the grooves irrespective of problems` of expansion and contraction, when shipping in knocked-down condition, the parts constituting the window frame.
By the utilization and embodiment of my invention in window frames theparts ofthe frame maybe shipped to the ob and there' assembled with convenience and accuracy, aA weather-tight joint between the pulley stile and the blind stop is insured; warping of `the parts is prevented, and a permanently true.-
groove is provided in which the sash may slide i without binding. The parts may also be ac-k curately assembled without the necessityof special tools and also without the necessity of skilled labor. r l :Referring now to the drawing wherein corresponding numerals represent like'parts, Figure l illustrates one complete example ofthe physical embodiment of the invention in a horizontal perspective view in section at one side ofthe windowframe; j Y,
Figures 2 and 34 are sectional views'y of a portion of a pulley stile with wedge-shaped. tongues and a blind'stop .or strip having complementary grooves in its face; V- n Figure l is a sectionalview partly in perspective of a portion of a window frame in which .asingle tongue and "groove is used, yand Figures 5`and6 .are sectional views showing respectively a portion ofthe pulley stile and a portion of the blindstop of Figure 4j This application is a divisional of' my a plication ASerial N o;,.`555,865,v filed April-1 ,j
shown, and the parting strip 4 is'secure'd inV the usual manner in the groove provide ,in the inner face of the stile.
,.The groove for the upper vsash is formed by the parting strip 4 andtheoverlapping edge 5 of the blind stop 6, the latter being partly-covered by the outer casing 7. The blind stop 6 is wider thanthe thickness of the pulley stile to provide the overlapping edge V5 after the. sash and a suitable number of nails are used to secure the blind stop in the edge of thepulley stile.
Y :For-useas guides in accurately assembling the parts, to secure a weathertight joint, and to interlock the parts to prevent warping, the
edige of the pulley stile adjacent. the blind stop is provided with a pair of spaced parallel tongues 9 and 10 which are wedgeshaped incross section, with both sides being correspondingly tapered, and these tongues areitted into complementary grooves 11 and 112 in the adjoining face of the blind stop. The depth of the grooves'is preferably greaterthan the depth of the tonguesin order that thefwedge-shaped tongues may be forced into'lthe grooves to `insure maximum frictional contact of' the `sides of' the tongues with `the`side walls of the grooves and Ito h'oldj the` adjoining faces of the Vpulley stile andthe blind. stop in 'close' contact. These' tapering-sides of the tongues and tapering side wallsofthe groove "also insure atight joint even .though shrinkage should take place lin either thev stile or blind stop. Y
The stile and blind stop are thus capable p oflbeing assembled-with accuracyV as the tongues and grooves act as guides to secure tightness and true alignment in assembling the parts. v Y v j 4In' Figures 4, 5 and 6 the invention is disclosed wherein the stile 13 has a single groove 14- and the blind stop 15 has a single complementary groove 16; application is. addressed to this latter invention.' Y
f -As willbe noted froman inspection of Figure 4, the blind stopl is grooved -near an ential expansion or contraction of the blind stop and pulley stile respectively.
The tongue and groove connection thus performs not only a wind baille but a weathertight, seal joint, as well. ,j
VAsi the grains of the stile and vblind stop run in different directions these parts themselves, together withk the tongues andgrooves, s
aid in stiffening the frame against warping and in maintaining the sash groove intruealignment, thus avoiding the danger of bindig the sash. Y
Having thus described my invention, what I claim is:
^ In a window frame, the combination with ay pulley stile having alongitudinally eX- tending "tongue near one side thereof, said tongue havin its-opposite edges correspondingly tapere vrelatively to each other to define a wedge-shaped element, of a'blind stop having a groove complemental in shape tothe. tongue, said groove being placed near the corresponding side of the blind stop, and a fastening device driven into the blind stop in a perpendicular 'direction whereby to equalize the compressive forces relative to said tapered contacting surfaces, said fas-v tening devicev being offset from thetongue and groove connection whereby to preventl The claim of thisv edge thereofandfthe pulley stile has formed `thereonfthe wedge-shaped tongue -14 near acorresponding edgethereof.l This is highly important because it provides a space for the nail 8, inl` a perpendicular. direction, wherebyto equalize compressive forcesrelatilve tothe taperedf contacting surfaces withoutysplitting the. tongue. If a tongueand groove-connectionwere placed in the middle,
