Application filed April 20, 1927. Serial No. 185,164.

This invention relates to window structures, and particularly to those employing steel sash.

The upper sash of a window is generally awkward to operate as it requires the opening of thefllower sash, unless a Window stick is used. I provide an operating handle by which the sash can be readily moved. T 0 this end I employ a hollow jamb, a sash weight inside the jamb and a sash operating handle connected to the weight, the jamb having a slot therein, and the handle projecting through the slot. The slot is preferably on the inner face of the jamb where it will be out of the way. The weight is connected to the sash by a cord or chain, and I preferably employ a second cord from the bottom of the window, passing around a pulley and extending upwardly to the sash weight so that there is, in effect, a continuous belt. This is particularly desirable for lowering the sash. I The weights for the top and bottom sashes generally lie side by side in the jamb, and I provide guide means for preventing interference between these weights. The operating handle serves as one guide, and I employ a separator inside the jamb as a supplemental guide.

In steel window construction, the sash is provided with sidewise extending plates which project through slots formed in the jamb. The slots ordinarily permit ingress of cold air, thus causing a drafty window. I provide a weather strip adapted to lie over the slot, when it is engaged by the sidewise exp tending plate on the sash, but free to move back' from the slot when it is engaged by such plate. The weather strip is preferably boxlike in character and formed with a pair of cooperating leaves. The plate extends between the leaves and into the space defined by the box-like weather strips. The leaves bend backwardly when they are engaged by the plate, but. if the sash is moved along the weather strip, close off the opening.

I further provide a convenient means for gaining access to the interior of the jamb. This is accomplished by leaving the jamb open on one or more sides, and providing a cover which fits over the opening. Preferably the cover is held in place by only a few small fastening members, but the jamb is so constructed that it has a recess engaging one edge of the cover plate.

I further provide flanges on the jambs the leaves spring together and which serve several useful functions. They are so positioned that they lie over and protect the edge of the plaster. They are also useful in that they accommodate a cover plate when it is desired to place two of my improved'frames side by side so as to make a mullion.

In the accompanying drawings illustrating the present preferred embodiment of my invention, and certain modifications thereof,

F gure 1 is a front elevation of a window,

Figure 2 is a vertical section to enlarged scale partly broken away, taken on line 11-11 of Figure 1,

Figure 2 is a view showing a modified structure providing a shelf,

Figure 3 is a horizontal section to enlarged scale partly broken away, taken on the line IIIIII of Figure 1,

Figure 3 is a section on the line III -III of a portion of the jamb,

Figure 4 is a view corresponding to a portion of Figure 3 and showing a modified arrangement of sash weights,

Figures 5 and 6 are cross sectional views taken through the weather strip showing its action, and k Figure 7 is a. view correspondin to Figure 4, but showing a. modified form of 1amb.

Figures 1 to 3 show a window frame comprising ahead 2, a sill 3 and hollow jambs 4.

Each jamb is made from a piece of sheet metal bent to form an outer wall 5, a back wall 6, a

double flange 7 and a guide member 8. A late 9 is secured to the back wall 6 and extends along the inner wall of the jamb. It carries a channeled member 10 which cooperates with the guide portion 8 to form a slot 11. The upper sash 12 works in this slot. It is provided with a sidewise extendplate 13 which projects through the slot ing sidewise movement of the window is limited by a strip 14 which holds the glass in lace in the sash.

he parts above described are the principal permanently installed parts of the jamb. It will be seen that this construction leaves an open front which makes the inside of the jamb readily accessible. The opening is covered by a plate of generally angular form, having a portion 15 which projects along the front face of the jamb, and a portion 16 which proiects along the inner face. The portion 16 is bent to form a guide member 17 cooperating with the channel 10 to form a slot 18. The

slot 18 accommodates the lower sash 19 of the window. This lower sash is provided with a sidewise extending plate 13*. Here again sidewise movement is limited by a glass retaining plate 14.

The outer edge of the portion 15 lies in a receptacle 20 formed at the front of the outer wall 5. This recess comprises the space between an outwardly turned flange 21 of the metal forming the jamb proper and a reinforcing angle 22 which is placed inside the jamb. The cover is held in place by screws 23 The sashes are provided with channel-like meeting rails 24 having flanges adapted to lie over one another, as shown in Figure 2. A spring-like weather strip 25 is provided to seal off the space between'the flanges. As shown in'Figure 3, the end portions of the meeting rails are provided with lips 26 extending into the channel-like space between the sashes and formed by the member 10. The small space at the bottom of this channellike groove is filled with a block 27.

The upper sash 12 is balanced by sash weights 28 connected to the plates 13 by chains 29. Pulleys are provided at the top of the frame to accommodate these chains. Similar pulleys and

chains

29 and 30 are provided for the sash weight 28 which balances the lower sash. The upper sash is also provided with a chain 29 extending from the lower portion of such sash around a pulley 30 at the bottom of the window and terminating in the bottom of the weight28. A handle is provided for operating purposes. It extends inwardly, then forwardly and then inwardly through a slot 32 formed in the cover portion 16. With this construction there is no need to use a window stick to operate the upper sash, nor it is necessary to open the lower sash. If the handle 33 is raised, the upper sash will be lowered, due to tension applied through the chain 29".

The handle member 31 acts as a guide and prevents interference between the

weights

28 and 28. Supplemental guide means comprising a plate 34 is also provided. These guide means insure that the weights will never strike one another.

By reason of the amb construction above described, there is provided a box-like space immediately behind the slots 11 and 18. Each of these box-like spaces is filled with a Weatherstrip 35 comprising a back and sides, and cooperating spring leaf portions 36. These spring leaf portions are bendable about the corners 37 of the box-like weather strip and when they are engaged by a

plate

13 or 13, they occupy the position shown in Figure 5. Those portions of the weather strip not engaged by a

plate

13 or 13" will lie in the position shown in Figure 6, thus sealing off the slot 11 or 18, as the case may be. It

will be understood t at if a

plate

13 or 13 is maintained at full 1 hickness for its entire height, there will be a relatively short tapered opening immediately above or below the sash, but in the main, the slot will be closed oil by the action of the leaf portions 36. It will be understood, of course, that the box-like weather strips extend the full height of the window frame.

Figures 2, 2 and 3 illustrate a construction which prevents chipping of plaster adjacent the window. Referring first to Figure 3, it will be noted that at the end of the flange 21 there is provided an outwardly extending flange 38 which overlaps the plaster P on the adjacent wall. With this construe? tion there is no danger of the plaster being chipped or broken out. At the top of the frame, the head 2 is provided with a similar outwardly extending flange 39. For an ordinary sill, such' as shown in Figure 2, no such construction is necessary because there will be no plaster to be engaged. In some cases, it is desirable to extend the sill outwardly to form a shelf, as indicated in Figure 2. In this case, I extend the sill outwardly to form a shelf 40 and then downwardly, as shown at 41. An angle member 42 is provided, thus leaving a recess 43 for the edge of the plaster, similar to the recesses provided by the

flanges

38 and 39.

An important advantage of the flanges 38 lies in the fact that they make possible a simple but very desirable mullion construction. This is shown in the right hand portion of Figure 3, where two adjacent flanges 38 are' covered over by a channel member 44.

The outer walls 5 of the j amb lie side by side and draw bolts 45 extend between them. A

washer 46 extends from one jamb to another beneath the channel 44 and a cover plate 47 is provided on the outside.

Figure 4 illustrates a modified construction wherein the upper sash 48 is balanced by a weight 49 lying at the inside of the jamb, and the lower sash 50 is balanced by a weight 51 lying at the outside of the jamb. This necessitates crossing the window chains over one another, as shown in the drawing, but permits of using an operating handle 52 which is on the front face of the j anib instead of on the inner face. With the construction either of Figure 3 or Figure 4, it is still possible to remove the cover plate for the jamb by removing the handle proper from the supporting member.

In either embodiment of the invention, it will be noted that removal of'the cover plate for the jamb will permit removal of the lowor sash, after which it is a simple matter to remove the channel members 10 and take out the upper sash. IVhile this can be readily accomplished from the inside, it cannot be done from the outside.

Figure 7 shows a modified construction wherein the inner face of the jamb is made substantially plane. This is done by terminating the back wall 6 of the amb in a the plate when engaged there flange to which is secured a plate 53. The plate extends backwardly and is then bent to form an inwardly extending portion 53, and is then bent again to form a forwardly extending portion 54. The front edge of the portion 54 forms one wall of a slot for the upper sash. The cover portion 16 forms one wall of a slot for the lower sashand the space between is filled by a plate 55 lying in substantially the same plane as the portions 54 and 16*. In other respects the construction is substantially similar to what is shown in Figure 3.

The invention as herein described is the present preferred form, but it will be understood that it may be otherwise embodied within the scope of the'following claims.

I claim 1. In a window construction, a. hollow frame member having a slot therein, a sash having a sidewise extending plate projecting into the slot, and a pair of weather strip portions extending over the slot from either side thereof, the portions being adapted to sub-- stantially close the slot when they are not engaged by the plate, but to move back from the slot when engaged by the plate.

2. In a window construction, a hollow frame member having a slot therein, a sash having a sidewise extending plate projecting into the slot, and a box-like weather strip lying behind the slot, the plate extending into the interior of the box-like strip, the strip having leaves tending to spring toward one another so as to close off the slot, but adapted to spring apart and lie on oplp site sides of 3. In a window construction, a hollow frame member having a slot therein, a sash having a sidewise extending plate projeotin into the slot, and a weather-strip lymg behin the slot, the weather-strip being hollow, having one edge portion engaging one side of the plate and extending around the ed e of the plate to engage the other side thereo the portions of the weather strip 1 ing to opposite sides of the plate being a apted to spring toward one another was to close off the slot.

4. In a window construction, a hollow frame member having a slot therein, a sash having a sidewise extending plate pro'ecting into the slot, and a weather-strip lying hind the slot, the weather-strip being hollow, having one edge portion engaging one side of the plate and extending around the edge of the plate to engage the other side thereof, the weather-strip substantiall filling the hollow portion of the frame mem er in which it lies.

5. In a window construction, a frame member, a relatively movable sash member, and a weather-strip carried by one of the members and engageable with the other mem-' ber, the weather-strip bein' hollow but having a longitudinally exten ing slot, the sides of the slot being movable toward or away from one another, the sides of the slot being adaptedto engage opposite sides of the member other than the one carrying the weatherstri 6.
