again folded back against the sash and are in position to balance the vertical movement thereof. At the same time the links 35 are folded back between the weather strip members 23 and 33 and hold the members 28 against vertical movement. Thereupon the sash moves vertically opened position as for ventilation, the pins 45 are moved into position in the openings 45 and may be brought to rest in notches 59 in the lower wall of the grooves 45 and the latches 53 are again swung up into engagement with the keepers 45 and enter the inner grooves 55 and thus hold the keepers against longitudinal movement. At the same time the latches close the inner ends of the grooves or passageways 45 and thus the pins 45 will beheld in the grooves while permitting limited movement of the upper edge of the sash ior holding the same in the position shown in 'Figure 3.

The upper sash 65 is guided and held in its uppermost or closed position by combined fixed weather strips and guideways 6I, preferably of in the weather strips 28 which serve as guides therefor.

The sash is held or controlled in its sliding and swinging movements by novel means which will now be. described. Brackets or bearing blocks 44 are set Iin recesses intheframe strips 24 and provide substantial continuations of such strips. These blocks have transverse slots or grooves 45 to permit the passage of pins 46 which extend laterally from the sides of the sash, these pins being `secured to the sash rails by integrally formed straps 41 as shown in Figure 10. When thesash is in normal or sliding position these pins move in the slots 23 in the sides of the frame and engage with the inner edges of the frame strips 24 to guide the sash in its vertical movement.

In order to prevent the pins from moving out through the grooves 45 during the sliding movement, keepers or guide members 43 Yare slidably mounted in the blocks 44 as shown in Figure 12, and have end portions 49 at right angles thereto for closing the inner ends of the grooves 45 or to make continuous guideways for the pins 45. These keepers are urged toward inner position by means of springs 50 which are interposed between projections 5| on the keepers and suitable abutments on the blocks. They are provided with handles 52 for drawing them out or to adjusted positions. Y f

These keepers are held in adjusted positions by means of latches 53 which are pivotedy at 54 to the blocks V44 and which have handles or projections` 55 for swinging the same. These catches engage with grooves 56 and 51 in the bar portions of the keepers 48. The sides of the latches 53 are also preferably notched as shown at 53 for engagement with the grooved portions of the keepers.

When the lower sash is set for sliding the keepers 43 are pulled out and the latches 53 are swung up to engage with the outer grooves 51 and hold the keepers in their outer or projected positions. When in such positions the lugs or projections 49 close the inner ends of the openings 45` as indicated in dotted lines in Figure 14 and the lower sash will slide freely in its ordinary manner.

When it is desired to swing the lower sash in- Wardly as for cleaning as shown inV Figure 2, the

substantially the cross section shown particularly in Figure 8. 1 These weather strips have channel shaped portions with legs 62 which engage with slots 63 in the sides of the sash and preferably have plates or back portions B4 which engage with the parting strips 25 and have flanges or ribs 65 which t tightly in grooves in the strips as shown. This construction makes a particularly weatherproof arrangement and prevents any air or wind from passing between the sash. The fixed guide members 5l terminate at approximately the center of the window frame or at the bottom of the top sash when it is in raised position. Somewhat similar combined weather strips, guideways, and pivotal supports 65 extend, when in normal position, from the lower ends of the guideways 6| V4to points adjacent to the lower portion of the frame where they are vpivoted on pivots 61 to longitudinal metallic strips 63 which are fastened to the parting strips as shown in Figure 9 and have ribs extending into the strips to make tight closures therewith. ,The guide members 65 are also channel shaped in cross section and have legs 53 which engage with the slots 63 in the sides of the upper sash when it is slid downwardly. These guideways have stops or projections 10 adjacent to the pivots 51 for limiting the downward movement of the sash, the arrangement being such that when the sash engages with said stops the upper edge will be substantially in alignment with the tops of the guide members 53, and freed from the fixed upper guide members so that thesash may be swung inwardly or to cleaning position by swinging the sash and the guideways therewith on the pivots 61.

The upper sash is also counterbalanced by means of any suitable weight or spring counterbalances which have supporting cords or ribbons 1I which extend from the frame or box in the usual manner. The lower ends of the ribbons 1l are secured to slides 12 which Vengage with vertical Vgrooves or guideways 13 in the sides of the frame in order to' guide or support them in their vertical movement. Links 14 are pivoted at V15 to the slidesj12 and are pivoted at their opposite or lower ends to the sides or the sash 55 by means of pivots 16.

In order to lock the sash 65 in the supporting member 55, or to prevent sliding of the sash out of such guideways when in lowered position, the ends of the links 14 extend a short distance beyond the pivots 15 and are adapted to engage with slots 11 in the legs of the rguide members 66 as shown in Figures v15 and 16.

When the two "windows are to besrwung in, wardly as forcleaning, theV lower'sash is irstY adjusted as shown in Figure 2. The upper sash is then pushed down until its top edge .is freeY from'the fixed guides 6| at which time the lower edge is in engagement with the stops 10. The top of the sash is then pulled inwardly to swing the same, together with the guideways 66 on the pivots 61. As soon as the upper edge of the sash moves out of alignment with the fixed guides the lower 4ends of the links 14 will be swung on the pivots '56 a suiicient distance to cause them to enter the slots 'l1 so that the sash will thereupon be locked in the guideways 66 and will remain locked until it is again s-wung to vertical position.

The sash may Valso be provided with transverse weather strips in the usual manner and other window hardware provided such as the catch 18 lfor locking the sash in closed position. The various weather strip and guide members may beiformed of extruded metal, rolled or made of sheet metal or in any desired manner to secure the shapes necessary for the various parts. It will also be noted that, while I have shown a double hung window, parts may also be utilized yfor single windows, and other changesmay be made in the details of construction in order to adapt the invention to different windows, without departing from the scope thereof as set forth in the following claims, in which I claim:

1. The combination of a window frame having vertical channels therein, strips and guideway members at. the sides of the frame, links connecting the lower portions of said members with the frame, slides movable in said channels, counter-balances connected with the slides, links connecting the slides with said members adajacent to the first-named links, pins on the sides of the sash which engage with the channels for guiding the sash in its vertical movey ment, and means for holding the pins in said channels at times, said means also being adjustable to permit the pins to be disengaged from the frame whereby the sash may be swung on said links.`

2. A device as per claim 1 in which the means for controlling the pins comprises blocks in the sides of the frame having grooves to permit the passage of the pins, keepers mounted transversely of the blocks, springs for urging said keepers to innermost position to close the channels, said keepers having projections to close the inner ends of the slots when in retracted positions, catches pivoted on the outsides of the blocks and serving to close the outer ends of the slots when swung to one position and also serving to engage with the keepers to hold them in retracted positions.

3. The combination with a window frame having channels therein, of combined weather strip and guideway members at the lower ends of said channels, links connecting the lower portions of said members to the frame to provide pivotal and swinging engagement of said members with respect to the frame, a sash having grooves in the sides for slidable engagement with said members, slides mounted in said channels, links connecting the slides with said members above said first-named links, counterbalances connected with said slides, pins on the sides ofthe sash which engage with said channels for guiding the sash in its vertical movement, grooves at the sides of the sash to permit the pins to be disengaged from the channels to lswing the sash on said links, and adjustable means for fastening thefpins in the channels and permitting them to be disengaged from the channels.

4. In a window of the character set forth, the combination of a frame, stationary channel combined weather,

shaped guideway and weather strip members extending from the top of the frame to approxi-l mately the middle thereof, a sash having grooves for engagement with the legs of said channel shaped members, similar channel shaped members normally in alignment with said iirst-named members and having their lower ends pivoted to the sides of the frame, guideways in the frame, slides mounted in said guideways, links connecting the slides with the sides'of the sash, counterbalances having ribbons connected with said slides, the lower ends of said links extending beyond their pivotal connections with the sash and adapted to engage with slots in the legs of said last-named channel shaped members, the arrangement being such that the window may be slid downwardly to engage with said lastnamed channel shaped members and then swung inwardly with said last-named channel shaped members whereupon the ends of the links will engage with the slots to hold the sash in xed position with respect to said pivoted members.

5. In a window, the combination of a frame, fixed guide members extending downwardly from the top of the frame, pivoted guide members normally in alignment with said iixed members and extending to the lower portion of the frame, means for pivotally connecting the lower ends of said pivoted guide members with the frame, a window sash slidably engaging with said guideways and normally held in sliding position, said window being adapted to swing with the lower pivoted guide members when in lowermost position and means for automatically locking the sash to said pivoted guide members when the sash is swung out of sliding position.
