Applicationllanuary22, 1952, SerialNo. 267534 3 Claims,

iIhis "invention relates to a window construction and more particularly ":to combined sash guiding channels and weather ,strippingnand .it consists in the constructions, arrangements and combinations herein described and claimed.

It ,is the cardinal object of *the .i-nvention to provide sash guiding channels wherein the tinherent resilience of the channels provide a weather-tight fit with the window frame and sash members and in which .a self-equalizingaction is provided upon the sash-without the need for sash Weights, springs or adjusting meanspthe sashbeing eiiectively held against sticking, binding or .frattling .and will -,-maintain .the -sash at a desired position against slippage due to vibrations.

.More specifically, it is an objectof:theinvention to provide a -pair.-of @opposed ,guide channels for reception of :sash, .-.one-of the channels being fixed againstlateral movement, while the other guide channel is provided with asash engaging member having ,a .seat .for .snug reception of .a rabbet of .the sash, the: seat having .a .lateral resilience exertinga pressure formaintaining the sash seated in ,the fixed channel, ,yet ,yieldable laterally in the .ov-posite wdirectionwpermitting ready removal of ..the sash, .as ..may he required.

,It is a still further .objectof .the invention to providesashguiding channels which are of extremely simple construction and which may lbe readily installed in neworo'ldbuilding structures by average workmen and with a minimum .of labor.

. Additional objects, advantages and features .of invention will be apparent from the following description, considered inconjunction with the accompanying drawing, wherein Figure .1 .is afhorizontal cross section through a double'hung window frame embodying the "use of the sash guide channels.

Figure 2 is a fragmentary perspective view of the movable guide .channel.

Figure 3 is a top plan View thereof.

"Figure 4 isaredu'ced end vview of the movable channelillustrating a modified form of *means for slidably mounting thefree end'of the channel.

"Figure 5 is asimi'lar view'o'i the fixed channel, and

"Figure :6 is "a modified form of the movable channel.

In the present instance, we have preferred to illustrate "the guide channels in a "double hung window construction, in which the sash are vertically slidable.

nttentionis first invited--to-Eigure "1 of the raw wher n a w ndow f ame was shown,

having the usual uprights H and 12. Then);- right H has apair of channels rld'formed therein and the upright k2 is provided with a pairtof channels M, the channels I33 and wi l rbeingiarranged in opposed relation, as is customar fin order to slidably mount a sash therebetween.

'Within respective channels 131a guide channel i5 is rigidly mounted :as will be described, while in the channels Hi 1a laterally movable guide channel 1-6 is secured, these guide channels A5 I and I6 extending the full vertical lengths of the channels l3 and M of the window frame.

The guide channels [5 and- IB are .iormedtrom a 'singlestrip ofsheet metal, whichin the use of aluminum window sash, will be vconstructedwfmm springsteel, spring zinc -or other suitable metal which will permitfree sliding movements of .the sash members.

As clearly shown in Figures 1 vand 5,-.the-=channel 5 consists of parallel side walls =|J .and 4.8. of such depth as to be properly accommodated within the .channel :3 ofa igiven sized window frame. lhe wall 1 1 is bent at right .anglesand then downwardly .to providea wall 19 which v en-- tends parallel to the wall ,I I forming. a .bead .ZB'. The wall l9 .is of .suitabledepth and bent .at right angles to form v.a seat 2! .for one vertical edge ..of a sash as will be explained hereinafter. A second seat 22 downwardlyoffset with irespect to the seat 2| is formed of substantial "width. The material of the channel 15 is .nextaben't .to forma wall 23 parallel to the wall 1.8,.these walls being connected by a wall 2d forming a bead 2'5 lying .in the .same horizontal planes .as the bead 2E1, but of greater width. The walls 111 and .I'B have their ends inwardly bent to form respective base portions .26 and '2]. The base portion 26 terminates approximately beneath the "bead '25, while thebase portion 21 is of greater length and terminates slightly beyond the medial vertical axis of the channel. The base ,portion 121! is formed with apertures 28 suitably spaced for tree ception of. mounting screws 29 for securing .the guide channels [5 within the channels "f3 Lof'ithe frame. The seat 22 is also formed with an opening 3.0 alignedwith each aperture '28 so as i.to admit .the blade of .a screw driver for actuating the screws.

'The laterally movable channel 15 will now --be described, attention being'invited particularly to Figures 1 and '2 of the "drawing, wherein it "will be seen that the guide channel 16 comprises "a base'foot -34 of a width to occupy the major 01 tion of the channel M of the frame and is anchored to "the avall of -the channel byi-means is! suitably :spaced screws f32 he base foot a l die the wall 33. The wall 35 stops short of the base foot SI and is reversely bent and continues upwardly at an acute angle as at 36 and thence bent in a horizontal plane to form a seat 37. A Wall 38 integral with the seat 31 and extended at right angles thereto is bent to form a bead 39 being horizontally disposed in the same plane as the bead 34. A wall 40 integral with the head 39 is provided, arranged in spaced parallel rela tion to the wall 38, and the wall 43 terminates in an inwardly directed flange 4| disposed beneath the head 39.

A suitable number of mounting clips 42 are employed in the installation of the guide channels I6 and in the present instance comprises a strip of aluminum bent into substantially Z-shaped formation providing a base 43 which is apertured for reception of suitable screws 44, an integral vertical wall 45 and a horizontal wall 45. However, in Figure 4, a modified means for slidably retaining the free end of the channel It is shown, wherein a screw 42' is passed through an opening formed in the flange 4| admitted through an opening formed in the bead 39. The shank of the screw is smooth for the major portion of its length and obviously a series of such screws suitably spaced will be employed in the mounting of the channel.

As clearly shown in Figure 1, the frame I includes respective parting strips 41 and 43 positioned between the pair of guide channels I and I6. The guide channels I5 are vertically positioned within the channels I3 of the frame II! and secured therein by means of screws 29, the narrow beads of the guides being presented toward the outsides of the upper sash 49 and the lower sash 50.

The guide channels I6 are next mounted in respective channels I4 of the frame and in this instance, a suitable number of clips 42 are properly positioned in the channels I4 next adjacent but spaced from the parting strip 48 and the inner wall 5I of the frame, with the flanges 45 presented toward the inside of the frame. The guide channels I6 are now positioned in the channels I4 and this is accomplished by presenting the flange 4| behind the horizontal wall 46 of the clip, which may be readily accomplished by virtue of the resilience of the metal forming the parts. It will be noted that the terminal end or flange 41 is unattached and free to be flexed permitting the wall 33 to move into position within the channel I4 of the frame I0. The guide channels I6 are then secured within the channel I4 by screws 32 and since the screws are located rearwardly of the inclined plate 36, openings 52 are formed in the plate to admit the blade of a screw driver. It will be apparent that the plate 36 and associated parts may be moved laterally inward so as to align the openings 52 with the screw heads, so that the screw driver may be readily manipulated.

The inner face of the upper sash 49 and lower sash 50 are each provided with vertical rabbeted edges 53 and 54 respectively, for accommodation of the beads and 39 of the channels I5 and I6.

In order to install the sash within the guides I5 and I6, the upper sash 49 is the first to be placed, which is accomplished as follows: The sash is arranged with the bead 39 seated in the rabbet 53 anda lateral pressure to the left as seen in Figure 1 will flex the inclined plate as and assoc ate parts inwardly of the channel, providing ample clearance to admit the positioning of the opposite side of the sash within the fixed channel I5 and when properly aligned, release of lateral pressure upon the sash, the latter will be moved into engagement within the channel I5. The lower sash will be similarly installed and obviously when it is desired to remove the sash for cleaning or other purposes, the sash is merely moved laterally against the resilient plate 36 until the fixed channel I5 is cleared, and preferably the inner sash 50 would be the first to be removed.

In Figure 6, a modified form of the movable channel is shown, wherein the inclined plate 36 is formed with an intermediate horizontal portion 55 through which an opening 52' is formed, aligned with the mounting screw 32, and eliminates the flexing of the plate 35 to align the opening with the screw.

From the foregoing it will be seen that we have provided guide channels which have a weathertight fit between the frame and sash members, the latter having a self-equalizing action by virtue of the spring tension of the movable channel and that no adjusting means are required to maintain a snug fit upon the sash members.

While we have shown and described preferred forms of the invention, this is by way of illustration only, and we consider as our own all such modifications in construction as fairly fall within the scope of the appended claims.
