A still further object of my invention is the Referring to the sashes, it can be seen that the provision of novel means for weather-stripping upper sash 20 embodies side rails 2| and 22, a the window sashes so that a leak-proof Window top rail 23, and a bottom or mid rail 24. The dewill be had when the sashes are in their closed sired typ of glass pan 25 can be Secured in po' 40 position, the weather-stripping allowing the free sition in any preferred manner.

The lower sash 30 is constructed simhereinafter more specifically described, claimed, ilarly to the upper sash 20, and hence includes 45 and illustrated in the accompanying drawings, in the side rails 3i and 32, the bottom rail 33, and which drawings: the top or mid rail 34. The desired type of glass Figure 1 is a front elevation of a window, showpane 35 is secured to these rails. The width of ing the features of my invention applied therethe bottom sash is such as to freely pass the stop to, parts of the window being shown broken away beads l4 for permitting the swinging of the lower 50 and in section. sash into the room when it is desired.

Figure 2 is a vertical section through the win- These sashes can be counterbalanced in any dow taken substantially on the line 22 of Figmanner, and in the present instance I have shown ure 1, looking in the direction of the arrows. the top of the window frame provided with Figure 3 is a fragmentary horizontal sectional spring drums 36 for this purpose, and these drums 5L.i

carry fiat metal strips 3'! which travel in the channels I9 in the stiles. These strips are secured to the sashes in a novel manner, as will be later set forth.

In accordance with my invention I provide metallic or other slide plates 38 for the opposite sides of each sash, and these slide plates are received between the meeting faces of the beads I4, I5, and I 6. Particular attention is invited to these slide plates, and it is to be noted that each of the same are of an elongated character, and have welded or otherwise secured thereto top and bottom short cross plates 39 and 48, which project beyond the longitudinal edges of the plates. These projecting ends of the cross plates 39 and 40 define guide ears or ribs 4i which are slidably received within the grooves II and I8 formed in the window frame. This construction allows the free sliding movement of the slide plates, and prevents the plates from being displaced from the window frame.

The upper ends of all of the plates have welded thereto, or otherwise formed thereon, hooks 42 for receiving the lower terminals of the flexible strips 31. Hence, the counterbalancing means is connected directly to these slide plates. The extreme lower ends of all of the plates are provided with openings 43, which loosely receive elongated pivot pins 44, carried by the lower ends of the pivoted arms 45. These pivoted arms are countersunk within the lower sides of the top and bottom sashes, and are secured to the sashes by the use of suitable fastening elements, such as screws or the like.

From the description so far, it can be seen that the sashes are mounted for free sliding movement with the slide plates, and can be swung on the slide plates into the room.

In order to lock the sashes against accidental swinging movement relative to either slide plates, the side rails ofboth the sashes carry springpressed bolts 46, which are adapted to fit within the keeper openings 41 formed in the slide plates. These keeper openings 41 are a material distance above the pivot points of the sashes, and hence when the bolts seat within the keeper openings, the sashes will be firmly held against opening movement. It is desired to utilize the upper bolts 46 for preventing the lowering of the upper sash by unauthorized persons, when the sash is in its completely closed position, and when the lower sash is in a partly open position for Ventilating purposes. Hence, keeper plates 48 are disposed within the channels I9 of the upper sash. These keeper plates 48 have their upper ends provided with abrupt shoulders or faces against which the bolts are adapted to rest. Obviously, when the bolts engage these faces, lowering of the window is prevented. The keeper plates are of a wedge shape so that the bolts will strike against the inclined faces thereof, when the upper window sash is being raised, so that the bolts will not have to be manipulated during the raising of the sash.

Obviously, the upper and lower sashes can be detachably connected together, when the same are in their completely closed position, by the ordinary window sash fastener (not shown).

As intimated above, the lower sash I3 can be partly swung into a room for ventilating purposes, and held in such position against further movement by unauthorized persons. To accomplish this the outer faces of the stop beads l4 have countersunk therein keeper plates 50, and these plates are provided with one or more keeper slots 5| for the reception of the bolts 46 carried by the lower sash. In Figure 5 I have illustrated the lower sash in its partly opened position, and to swing the sash partly in the room the sash is raised a slight distance and the bolts are moved inwardly towards one another, and out of the keeper recesses 41 formed in the slide plates 38. The sash is now swung on its pivots 44 the desired distance into the room, after which the bolts are released for movement into the preferred keeper slots 5|. Obviously, persons on the outside of the window cannot reach the bolts to. manipulate the same.

When it is desired to swing the lower sash completely into the room, either for ventilating purposes or for washing the opposite faces of the window pane, or for re-puttying the pane, the sash is slightly raised and the bolts moved inwardly toward one another so as to release the sash from its slide plates. The window sash can now be swung completely into the room, but during the swinging movement the slide plates have a tendency to raise, which acts as a disadvantage when the outer face of the pane is being washed. I therefore provide manually actuated slide bolts 52 carried by the side stiles of the window frame. These bolts 52 can be mounted in suitable housings, or the like, 53, embedded or countersunk in the styles. These bolts 52 are adapted to be moved in the path of the slide plates 38 for the lower sash, and hence upward sliding movement of the plates is prevented.

Means can also be provided for preventing upward sliding movement of the slide plates for the upper sash when the upper sash is swung into the room. This means can consist of stop pins 54 carried by the stop beads I5 adjacent to their lower ends, and the lower or mid rail 24 of the sash can carry fingers 55. Thus, when the upper sash is moved to its lowered position, and swung into the room, the fingers 55 will engage the pins 54, and upward riding movement of the sash will be prevented.

In Figure 6 I have shown both of the sashes swung into the room, and obviously when the sashes are in this position the outer side of the pane of the upper sash can be easily washed and re-puttied if the occasion demands. It is to be also noted that when the sashes are in this position complete ventilation is had through the window opening.

It is essential that windows of this character be thoroughly weather-stripped so that the same will be leak-proof during inclement weather and the winter season. In the drawings I have illustrated one efficient means for weather-stripping the window, and, as shown, the parting and stop beads I5 and I 6 are provided with metallic strips 56 and 51, respectively, which are adapted to fit within longitudinal grooves formed in the side rails of the sashes when the sashes are in their vertical position. The top rail 23 of the upper sash is provided with a groove 58 for receiving a metallic weather-strip 59 carried by the lintel l2 of the window frame. The bottom rail 33 of the lower sash is provided with a groove 59 for receiving a metallic weather-strip 60 carried by the sill I3. The mid rails of the top and bottom sashes carry the interfitting metallic strips 6|.

In order to hold the lower sash firmly in its lowered position against rattling movement, I provide leaf springs 62. These leaf springs 62 are set in the lower ends of the channels I9 for the lower sash. When the sash is moved to its lowermost position, these springs engage the slide 30 lower cross plates carried by the slide plates proplates 38 for the lower sash and the pivot pins 44. Hence, all side or lateral shifting movement of the lower sash is taken care of.

From the foregoing description it can be seen that I have provided an exceptionally simple and durable means for forming a window having sashes capable of both sliding and swinging movement.

Changes in details may be made without departing from the spirit or scope of my invention, but what I claim as new is:

I claim:

1. In a window construction, a window frame having stop and parting beads, the opposite faces of the beads being provided with vertical guideways, slide plates slidably mounted between the beads having upper and lower guide ears projecting laterally beyond the longitudinal edges of the slide plates slidably received in said guideways, arms pivotally mounted to the lower ends of the slide plates, Window sashes for the frame, means securing the arms to the outer faces of the side rails of the sashes, and means for detachably locking the sashes to the slide plates at a point spaced from the pivot pins of the arms.

2. In a window, a window frame including stop and parting beads, the facing sides of the beads being provided with vertical guide-ways, slide plates mounted between the beads, upper and jecting beyond the longitudinal edges thereof and received within the guide-ways, pivot arms having pivot pins loosely received within the lower ends of the slide plates, window sashes for the frame, means connecting the pivot arms to the sashes, the slide plates being provided with keeper openings above the pivot pins, and lock bolts carried by the sashes for movement into and out of the keeper openings.

3. In a window, a window frame, including side stiles having longitudinal channels and stop and parting beads, facing portions of the beads being provided with vertical guide-ways, an upper sash, slide plates for the upper sash received between the parting bead and one stop bead, laterally projecting guide ears on the slide plates received in the guideways, pivot arms secured to the sash having pivot pins loosely received in the lower ends of the slide plates, the slide plates being provided with keeper openings, spring-pressed bolts carried by the sash for movement into and out of keeper openings, and latch plates disposed in the channels having abrupt upper ends disposed in the path of the bolts for limiting downward movement of the slide plates and the sash, the outer face of the keeper plates being inclined. toward the abrupt face, as and for the purpose" specified.
