In theembqdimentshewn, both'side rails 15 `and116 and top rail 17 are equipped with eXPanders of the character shownandvdescribed in `anyPatent No. 2,768,410. `As n the` sash of that patent, Vthe'eXpander Vscrewsmay beY omitted `from oneof.,the side rails.

:.f-Inithe :embodiment shown, `thelssliding Iinserts and 7 are identical. Each of them is provided with a frame made up of a top rail 30, a bottom rail 31 and side rails 32 and 33. Each of these rails is identical, and includes a glazing groove 34, and an outwardly extending flange 35, which runs continuously around the outside of the frame. The frame is held together with metal screws 36 extending into holes 37, formed when the frames are extruded. Panes 38 of glass, are held in position and sealed by means of rubber or vinyl channel shaped sealing strips 39 seated in the grooves 34.

The inserts 6 and 7 are put into the channels 25 and 26 of the frame in the usual manner of sliding windows. That is, the flange 35 along the top rail of the insert is inserted into the channel of the top rail of the frame and the insert is raised as high as it will go, at which time the lower edge of the flange of the bottom rail of the insert will clear the upper edge of the sill rail track, permitting the window to be lowered into place with the flange of the bottom rail of the insert within the channeltrack of the sill rail. This is shown in Figure 4, where, in dotted lines, the position of the insert for removal or replacement is shown.

The center post S is preferably an extruded bar, and is rigid. In the embodiment shown, it is provided on its front and back faces with mortises t) running the full length of the post, for the reception of sealing strips 5l which, in the embodiment shown, are wool pile. On its tWo side faces, the post is provided with channels 52 over which lips 53 extend part way.

At the top of the post 3 is a pad 55 of felt, rubber or other resilient material. Extending from the top of the post 8, near one side face, are two pins 56, projecting through and beyond the felt pad 55. At the bottom of the post 8, in the channel 52 on the side of the post at which the pins 56 are located, is a sliding block 60. The sliding block 60 carries a pin 6l projecting downwardly from the block 60. A handle 62 is fastened to the block 6i), and projects beyond the post 8, between the lips 53, as shown in Figure 6. A spring biased detent 64 is carried by the block 66 and projects from the inside face of the block. The detent 64 is received in the upper position of the block 60 (shown in Figure 5) by an upper dimple 67, and in the lower position of the block (shown in Figure 4) by a lower dimple 68. The upper dirnple 67 serves to hold the block in position with the pin 6l clear of the end of the post.

Also mounted on the post 8 is a universal locking device 70. The locking device 76 consists of a pair of rotatable blocks 71 mounted on opposite ends of a shaft 72.

The shaft 72 extends through a hole in the web between the two channels 52 of the post 8. In the embodiment shown, the shaft 72 has a head 73 at one end, an a nut 74 on the other, threaded, end. The blocks 7l are mounted asymmetrically on the shaft 72, so that one end 75 of each of the blocks projects beyond the reach of the sealing strips 5l, when they are turned in the direction shown in Figure 2. Mounted on the end 75 of each of the blocks 71 is a movable latch member 80, having a handle member 81. The latch Sil is mounted on the block 71 by means of a screw 82, which permits the latch 81 to be rotated manually.

The rails of the frame 5 of the embodiment of window shown in the drawings, are joined rigidly by any suitable means, such as bolts, rivets, or the like, to form the frame 5. The frame 5 is rigid and square. The frame is then set into the window opening, and the expanders are moved outwardly against the faces of the walls deiining the window opening by screwing the screw members, shown in Figure 2, until the felt strips of the expanders tightly engage the walls defining the window opening. As is explained in connection with the storm sash of Patent No. 2,768,410, the expanders conform to the contour of the wall, leaving the frame of the window rigid and square. The center post is then put into place by inserting the upper pins 56 into holes 59 in the web of the upper rail, as shown particularly in Figure 5, and, when those pins are in position, and the post is positioned vertically, by pushing the sliding block 60 against the bias of the detent 64 in the upper dimple 67 until the detent clears the dimple to permit the lower pin 6l of the block 60 to enter hole 69 in the sill rail. The entry of the detent 64 into the lower dirnple 68 holds the block 60 in that position.

The pins 56, being set near the right edge of the post 8, as viewed in Figure 5, make this post readily insertable from the right, by moving the lower end of the post clockwise, since the pins will make contact with the hole 59 in the upper rail while the lower end of the post is still swung well away from the vertical. It can be seen that by making two sets of holes in the upper and sill rails, the post can be installed from either side. The pad 55, being resilient insures a tight tit, and permits the post to be installed without distorting the frame. The locking device 70 is put into the position shown in Figure 3, with the blocks 7l turned to the position at which they lie substantially parallel with the channels 52, and with the latches 30 turned outwardly at right angles to the post 8.

The inserts 6 and 7 are then placed in position in the channels 25 and 26, as has been explained heretofore.

It can be seen that it does not matter whether the inserts 6 and 7 are put respectively on the inside or outside of the window, or on the right or left side of the post 8. They are interchangeable. When, as shown in Figure 2, they are in closed position, the flange 25 of the side rail 32 of each of the inserts is within the channel 25 or 26, as the case may be, of the side rails and 16, the anges of the top and bottom rails of the inserts are within the channels and 26 of the top and sill rails of the frame, and the anges of the rails 33 of the inserts 6 and 7 are snugly against the sealing strips 5l along the full length of the post 8.

In order to lock the windows in position, the outside insert is first pushed to its closed position, while the inside insert remains at least partly open. The block 7l on the side of the post adjacent the edge of the ange of the rail 33 of the outside insert is turned at right angles to the post, and the latch is turned to engage the outer side of the ange, as shown in Figure 2. The latch is tapered slightly so as to wedge the flange and rail 33 against the felt 51. The inside insert is then slid to its closed position, and the remaining locking device is positioned similarly to lock it in position and to hold it snugly against the sealing strip 51. It can be seen that the locking members are arranged to operate on either side, so that it makes no difference whether the insert 6 is on the left side and the insert 7 is on the right, as shown in Figure 2, or whether their positions are reversed. The locking device is operative in either position.

In removing the inserts, the inner insert 7 may be taken out, the removable post 8 taken out, and the outside insert 6 removed. If the window l is a storm window on the inside of a sliding prime window, the inserts of the sliding prime window can be removed through the frame of the window 1. If the prime window is of a different type, it can be washed, or replaced, as if the frame of the window 1 were not there.

Numerous variations in the construction of the window of this invention, within the scope of the appended claim, will occur to those skilled in the art in the light of the foregoing disclosure. For example, various means may be used to keep the sliding block 69 in place. The handle 62 can be provided with a threaded shank, engaging in a threaded hole in the block, so that the handle can be tightened against the surface of the web of the post 8 to maintain it in any desired position. In lieu of the two pins 59 in the upper end of the post 8, a short slot may be provided in the web of the top rail, yand a short tab or ear can be provided on the top of the post 8. In order to facilitate the installation of the post, a small stop member can be provided on the under surface of the web of the top rail, adjacent the corner of the post in its mounted position, so that the post can simply be slid until it reaches the stop, and the pins inserted within the holes in the top rail. The kinds of sealing strips which are used form no part of this invention, and can be made of any suitable material. Also, the precise configuration of the various members, and their means of joining, may be varied without departing from the spirit of this invention. Thus, for example, the frames of the sliding insert panels may be mitered at their corners, instead of being butt joined. The center post may have a different cross-sectional coniiguration, so long as provision is made for sealing members along the sides, and for accommodating some form of anchoring means at the top and bottom of the post. So also, the sill rail may be given a different cross-sectional configuration, although the one shown has the advantage of permitting the insertion of a sealing strip at the bottom, as shown particularly in Figure 4'. The locking device 70 can also be somewhat differently constructed. For example, the shaft 72 need not have a head at one end and a threaded section at the other. It may take the form of a pair of tap screws, or a double ended threaded shaft, or it may simply be peened at the ends, for example. I-t may also contain a means for biasing the 4block members 71 toward the post, so as to hold them snugly and continuously in frictional engagement therewith.

In windows more than about four lights high, a cross bar can be run between the side rails of the frame, to delne an upper window area and a lower window area. Normally, the upper window area will be in the nature of a transom, with a single light which is not designed to slide. However, the upper part of the window can also be made with sliding insert panels. The cross bar is preferably made inverted U-shaped in cross section, with a heavy, thick web between the depending legs of the U. `Outboard of each or the legs are two, oppositely directed receiving lips, one forming a channel into which the flange of the upper rail of the insert panel of the lower window extends, and the other forming a channel or track into which the lower flange of the upper window panel extends. When such a cross bar is used, the center post of the lower window extends into the channel between the depending legs, and requires only a single pin top and bottom, because the post is held against turning by the legs of the cross bar channel.

Having -thus `described-the invention, what is claimed and desired to be secured by Letters Patent is:

In a window structure of the horizontally sliding insert type, the improvement comprising a window frame with upper and sill rails having inner and outer panel-retaining means, a vertical center post extending between the upper and sill rails and intermediate the inner and outer panel-retaining means, and manipulable mounting means releasably connecting said vertical center post with said upper and sill rails, said center post being provided with a universal lock comprising blocks mounted on opposite sides of said center post on an axis at right angles to the long axis of said post, for movement between a position With the long axis of the block parallel to the long axis of the post to a position with the long axis of the block at right angles to the long axis of the post, and a latch member rotatably mounted on an end of said block on an axis parallel with lthe long axis of said block.
