One of the objects of the invention'is to pro vide sash guides particularly designed to facili tate the installation and removal of window sashes. a 7

Another object of the inventionis to provide improved sash guides w ich more .a wood to metal contact on the siidmgsur'races; in a con struction which may readily be assembled Q1 disassembled.

Another object of the inventi n is .to provide metal sash guides constructed for ease of fassembly with the window sashes 'aiid with the.

window frames in which they are to be placed to decrease the time required for installing windows, and yet provide a window construction which has excellent weather-proofing character.- istics.

Numerous other objectsand -.advantages.of the invention will be particularly pointed out hereinafter or will become apparent from a reading of the specification and upon reference to the drawings.

Referring further to the drawingaat: the v0D- posing sides of therwinjdow f rameithere. are provided the following assemblies 110i ,metal parts. One strip of metal rising :lverticallyqaat the :right side ofthe window :frame is generallyidesignated as-Aand includes. a;fiat slideway le-for theinner sash .flprovided ;at yvertioal' intervals [with holes such as v2 and .aceU'j-shapedschannelmontlon 1173'.

which. fits snugly into a groove 4 provided in the vertical window frame member 5.

Beyond .thechannel 3 toward the outside vof the window is another flat slideway .6 which terminates at a folded flange I, outside of which the strip is folded back upon itself providing .a channel'between thesurfaces 8 and 9 into which the screen guide or retaining strip is fitted, as will be better understood by reference to Figures 1 to 3inclusive. The'fiange 1 serves as the out' side guide for the upper sash.

The screen guide or retainer is the structure generally indicated as B iii-Figure 4 and has two portions Ill-and ll which interlock with the por tions '8 and -9 of the strip A, with the outside retaining flange -I2--folded-back upon itself, as illustrated. The frame of the screen is indicated as l3-i-in Figure 1.

is apparent in Figure :1, the strip C at the left-side of the window frame is-identic'al with the right hand stripA, as thus far described. Howevenas will be explainedlater, onehas an integral inside -guide -for the inner sash, while the other has a separable inside guide. The screenretainer D is "similar to B.

The -vertical metal stripsA, B, C, andD are assembled and inserted into the window frame member's-s and -I4, and are secured therein "by na'fls, screws, or in any other suitable manner. Thereafter, theupper sash I5 will-be inserted until it occupies the position shown in-Figure 2. Next, the parting strips 11 and 16, which are fielded-strips of metal having considerable resllie'nc'e which tends :to spread their vertical legs apart; are inserted into the channel 3- in the vertical-metal strip -A,- and into the corresponding' chann'el in strip -C. These parting strips hold the sashes snugly against the opposing guide -'-fl'anges, yet permit them to slide freely from the top to' -thebottom of-the window frame. The resil-ient legs on the parting strips, bearingon the--ihsides0f the "channels 3, prevent-any passage-of lair therethrough, and thus serve also as weather strips.

The-lower' 'sash l 8 --may now be inserted, 'inthe manner indicated in-Eigure .2,\until it'occupies the f-ullyinserted positionof Figure 1. Thereafter;a-removablestrip, generall indicated as E, having-oneleg I9for contactingthe verticalinner surfacebf the lower sash and another leg --20 whichmay be inserted between the section 2 of the-guide A and the:adjacent surface of the windew-frame 5, is-inserted until it occupies the position shown in sFigureil. After itis in place-the screws j l, {which had-previously been loosened will now be tightened, thus locking the section 2 against section 20 which will hold the part E firmly in place. The screws 2! may be spaced at any desired intervals to pass through holes 2 in the guide member A and through V-shaped notches 22 provided in the guide E. Thus when the screws are slightly loosened, the member E may easily be withdrawn. By running the inner or lower sash up or down access to all of the screws is easily obtained.

The integral flange 23 on the vertical sash guide shown at the left of Figure 2 cooperates with the resilient parting strip 16 to snugly guide the inner sash.

Preferably, the removable guide E and the permanent guide 23 will extend the full height of the window frame in order to provide a uniform guide for the inner sash all the Way to the top of the window and to afford a uniform appearance. The removable part E, however, is easily removed simply by the use of a screw driver, while the parting strips l6 and ii, after the inner sash has been removed, are easily pulled out either with the fingers or with a pair of pliers. Thus it will be :appreciated that without any unusual equipment :in the way of tools, both sashes may be removed or reinserted with great ease, and yet when they :are reassembled and locked in position the entire :assembly affords an excellent weather proof con- .struction with metal-to-wood sliding contacts for lboth sashes.

Referring now to Figure the construction at 'Ithe bottom of the window frame is exceedingly simple, it being sufficient to provide only a single strip 0f metal extending across the bottom of the frame, this element being generally designated as F and being shaped as indicated to provide one flange 24% which faces against the bottom window frame member 25, the folded section 26 upon which the screen sash i3 may rest, a middle section 27 located as indicated at the bottom of the sash slideways, and an upwardly extending folded .flange 28 which is adapted to extend into a groove 229 provided in the lower sash l8. A folded section 35 on the part F completes the horizontal :surface on which the bottom of the inner sash :rests. The folded flange 28 and the groove 29 in the sash contribute to the weather stripping of the entire assembly. Of course when the inner .sash is being removed it is first lifted off the flange 28.

Figure 6 shows how the top or the window construction is finished to cooperate with the parts heretofore described to provide a neat, weather proof construction. A single metal plate extends across the top of the window frame, being generally designated by the letter G, and has a downwardly extending flange 3i adjoining a horizontal section 32. A channel 33 is formed therein similar to the channel 3 and extends into a corresponding groove, not shown, in the adjoining top member of the window frame. A horizontal section 35, and a downwardly extending flange 3:? complete the metal construction at the top of the window. I provide a folded metal insert 36, similar to the folded parting strip ii, to fit snugly into the channel 33, preventing the upper edge of the .outer sash from rattling and holding it snug and in a weather proof relationship. The insert 36 may be made removable or not, as desired. It does not require removal during the insertion or removal of the upper sash, for it will be apparent that the upper sash may be lowered before re- ,moval sufiiciently to clear the insert 36.

In view of the narrowness of the parting strips 4 l6 and I! only a narrow ledge 31 need be pro vided on the inner sash to effect a tight seal with the lower margin of the outer and upper sash, as shown in Figure 6.

The construction herein shown and described is easily coordinated with a wooden box frame for the window, as is indicated in the drawings: Obviously a metal frame may be used instead of a wooden frame.

Although I have' shown and described one ar:- ticular embodiment of my invention, I do not desire to be limited to the exact details of construction herein shown and described. It should be understood that the invention comprehends all variations and modifications within the scope of the appended claims.

I claim as my invention:

1. Sash guides for embracing opposite mafgins of inner and outer sliding sashes comprising a sheet of metal adapted to be vertically positioned in each of the opposing vertical margins of a rectangular window frame, each sheet of metal having parallel slideways for the inner and outer sashes, a right-angle flange at the outside margin of the outer slideway in each sheet forming a lateral outer guide for the outer sash and an inner guide for a screen frame, a narrow channel in each vertical sheet between said slideways extending laterally outside the plane of said sash slideways for interfitting with a groove in a vertically grooved window frame, removable, laterally expansible, metal parting strips inserted into said channels, consisting of strips of metal bent upon themselves to form adjacent resilient legs, the inner sash slideway at one side of the window frame having an integral right-angle extension constituting an inner lateral guide for the inner sash, and a removable vertical strip of right-angle transverse cross section having one right-angle leg overlapping the inner sash guideway at the other side of the window frame, and its other leg providing an inner lateral guide for the inner sash, and means for releasably securing the last said strip to said inner sash guide and a surrounding window frame in said overlapping position.

2. Vertical sash guides for a window having two sliding sashes, comprising a sheet of preformed metal for each of the opposing vertical sides of the window frame, each sheet having a flange thereon to constitute an outside guide for the outer sash, two parallel surfaces in each sheet constituting slideways for the outer and inner sashes, and separated by a U-shaped channel extending laterally outside the plane of said sash slideways for interfitting with a groove in a vertically grooved window frame, an integral flange on one said sheet forming the inner guide for the inner sash, a removable flange constituting an inside guide for the inner sash, said guide being detachably connectible to the other preformed sheet, means in the inner slideway of said other sheet for securing said removable flange to said inner slideway in operative position, and a pair of resilient metal parting strips inserted into said U-shaped channels at opposite sides of the window for yieldably pressing the two sashes against their adjoining outer and inner guides and providing a weatherproof seal between the sashes and the parting strips.

3. In combination with vertical sash guides as set forth in claim 2, a member adapted to be placed in the top of the window frame to cooperate with the upper ends of both sashes and having a cross section transverse to its length identical with the transverse cross section of the first described vertical sash guide, and a U-shaped window frame, a laterally expansible removable metal parting strip for each channel, inner and outer sash slideways in each sheet on opposite sides of said channel, one sheet having an integral flange constituting an inner guide for the inner sash, a removable metal strip of transverse right angle cross section having one leg constituting an inner guide for the inner sash and its other leg being inserted between the inner sash slideway of the other sheet and the window frame, and means releasably locking said latter strip in operative position.
