(ci. 2li-521) 1 claim. 1

This invention lrelates'to window construction, and more particularly has reference to the type of window `construction that is particularly adaptedrfor 'use in concrete Abuilding structures, although it can as well be used in structures of other types.

An important object of the present invention is to provide a window construction wherein a plurality of channels are utilized, with each channel accommodating double hung sashes, the upper and lower sashes of each channel adapted to be recessed entirely within the wall above and below the window frame.

lAnother important object is to provide a window construction of the type stated wherein one set of sashes can be equipped with the usual glass panes, another set can be formed as screen sashes, and the third set can comprise reproof shutters of vermiculite or similar material.

Another important object is to provide a Window construction as stated wherein the upper and lower sashes of each channel have a cord and pulley connection with each other in such a way that the raising of the upper sash into the recess above the window will cause the lower sash to be dropped into the recess below the window, so that both of said sashes will clear the window aperture entirely if desired.

With the foregoing and other objects in vieW which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Fig. '7Y is a section on line 'i-l of Fig. 6.

.Referring to the drawings in detail', I have v2 particularlydesigned the window assembly .to be described hereinafter, so that it may be utilized in buildings'con'strcted allor in greatest part of `concrete or similar cernentitious "material. However, at this point it should be noted that as will be apparent hereinafter, the 'construction 'of the Vwindow assemblyY does not preclude its "use in other types of building structures.

In any event, in the illustrated "example a concrete floor 5 is provided-and a concrete 'ceiling i6, 'while 'I designates a concrete building wall `formed with an aperture for a window, and set into the concrete wall 'l at the sidesof saidaperture are the concrete posts 8.

Above the window aperture, I provide (Fig. 2) ain'inner top wall slab 9 andan outer top wall slab I0 spaced apart to define a jpocketil 'in which the 'upper sashes of the window assembly are adapted to be recessed in a manner t`o be 'described hereinafter.

Below the window aperture I provide the inner bottom slab I2 and the `outer bottom slab I3 spaced apart to define the lower pocket vlli 'receiving the bottom sashes. l

If necessary the pocket II can be 'extended upwardly above the ceiling 6 as shown lat I5, and the pocket I4 can be extended below 'the oor 5 as at I6.v K,

Mounted against the concrete posts 8 'are parallel vchannels I1, I8, andv I9 `respectively (see Fig. 5) and these are oija length to extend upwardly 'along the side walls of the respective lupper and lower pockets to the inner ends of said pockets. The channels I1, I8, i9 can be securely mounted in place in any suitable 'manner, but I prefer that the channels 'be vformed with openings 20 `-adapted to receive screws that can extend into the concrete posts 8 int'o threaded engagement with nuts embedded in said posts.

The channel I1 is adapted to provide-aslideway for the upper and lower window sa'shes, the channel I8 is adapted to provide a slidf'eway 'for the upper and lower screen "sashes, andthe channel IS is adapted to provide laslidewiay for the upper and lower Vflreproof shutters.

The construction of the window sashes. which will be the innermost pair of sashes in. most instances, will first be described, and the upper and lower window sashes are `generally-designated 2| and 22 and :are shown in partially open or recessed position in 1. yThe uppersash 2| is typical, and is provided with a metal frame including (Fig. 5) side plates 23 ofjme'tal ma.- terialwelded at 24, to horizontal plates` 25,;at the top and bottom of the sash. Horizontal this end, there are secured to the opposite sides of the sashes the outwardly extended channeled guides 3i (see Fig. 5) which are mounted for sliding movement in the respective sash runs or -channels Il.

By reason of this construction it will be seen that slidable mountings for the window sashes are provided, with there nevertheless being provided at opposite sides of each sash openings defined between the opposite side Walls of each of the channeled guides 3i These openings or vertical passageways are for a purpose to be apparent immediately hereinafter, there being secured to the respective upper corners of the upper window sash 2i the sash cords 32 that are extended upwardly as best seen in Fig. l, and are trained over pulleys 33 mounted cn brackets extending outwardly from the upper ends of the respective channels l1 as best seen in Fig. 4. Thereafter, the sash -cords 32 are extended downwardly within the channels il and are extended through the passageways described immediately above V(see Fig. 5). The lower ends of the sash cords 32 are then connected to the upper corners of the bottom sash 22.

By reason of this construction, it will be readily seen that when the upper window sash 2| is raised by a, user, the lower window sash 22 will move downwardly. Assuming that the upper sash 2| is raised to its maximum extent, in which it is recessed fully within the top pocket, the bottom sash 22 will be moved downwardly a corresponding extent, so that it is fully recessedwithin the lower pocket. Thus the window aperture is cleared entirely of theV sashes. In this connection, it will be appreciated that the sashes are of substantially identical construction, and are of the` same weight, so that one counterbalances the other during the raising andY lowering thereof.

Referring to Fig. '7, to the outer surface of the horizontal lower rail 2S is secured a plate 35 that extends downwardly over the joint between the top and bottom sashes when said sashes are in closed position as illustrated in Fig. 7, so as to provide a drip strip or joint covering means to preventleakage through the sashes to the interior of the building structure.

I believe that various means can be devised for locking the windows in closed position and open position. However, I prefer that a means such as shown in Fig. 6 be used for this purpose. In this gure there is illustrated a means for locking the windows in closed position wherein a swinging latch 36 has a beveled hook 3l at its lower end adapted to engage in registering openof swinging said latch to open or unlatching position when the hook 31 is out of engagement with the bottom sash 22. For this purpose, the shaft di extends out of the sleeve 40 as best seen in Fig. 7, and is extended laterally to provide an operating handle 32 accessible from the interior of the building structure. When the window sashes are moved to closed position, the cam portion or beveled surface of the hook 31 will be cammed outwardly so las to permit the latch to enter the registering openings 38 and 39 after which the latch 36 will automatically move to a position in which the hook 31 will engage the bottom sash. A stop 43 is provided limiting movement of the latch in one direction, and for the purpose of automatically engaging the latch with the bottom sash, I provide the spring 43* secured to the latch and to the bottom rail of the upper sash respectively.

I also provide a means for locking the windows in any selected open position, and to this end there is provided in the top rail of the bottom sash a sliding bolt arrangement wherein a sleeve 45 extends through said top rail of the bottom sash and has rotatably mounted therein the shaft i3 of non-circular cross section, there being secured to the projecting portion of the shaft 35 the operating handle il for rotating said shaft.

. Secured rigidly to the inner end of the shaft 43 ings 38 and 39 of the top and bottom sashes re- Vwithin said sleeve the shaft il! of non-circular cross-sectional conguration that is engaged with the upper end of the pivoted latch for the purpose for rotation thereby isV the disc 38V and pivotally secured to the disc at diametrically` opposite points are the retractable bolts 49 that extend through openings in the opposite sides of the bottom sash so as to engage in any of a series of openings spaced vertically of the channels il thus to permit the vsashes to be locked in a selected openposition by adjustmentvof the bolts i3 to the dotted line position illustrated in Fig. 6.

Referring now to the construction which I prefer to utilize for the middle set of sashes comprising the screen sashes, reference Ashould be had to Figs. 2 land 3 .in which it is seen that each screen sash is provided With a frame which is formed from channel members 5i) in which are mounted wood fillers El. Screen mesh material 52 has its marginal portions engaged under retaining strips 53 formed with suitable openings through which screws extend for the purpose of securing the marginal portions of the screen mesh material between the strips 53 and the wood fil-1ers 5l. TheseY screen sashes formed as described are connected by a cord and pulley arrangement exactly `as in the case of the window sashes, and the screen sashes slide in the middle channels I3. Thus, elevation of one screen sash to its maximum extent causes the other screen Sash to drop into the bottom pocket to its maximum extent so as to clear the window aperture entirely of the screen sashes whenever desired. This would be desirable in the wintertime perhaps, or on any other occasion when screen sashes are not necessary.

Referring now to othe outer channels i 3,' these accommodate slidably mounted iireproof shut ters the construction of which is best shown in Figs. 2 and 3, each fireproof sash comprising a frame composed of channel members 54 einbracm ing the marginal portions of a vermiculite shut- Y ter member 55 reinforced by wire mesh material 56.. Ordinarily, thereproof shutters can be recessed entirely within the upper and lower poehets, but if a fire occurs in a nearby structure, the shutters can be swiftly moved to closedV position, and in said position will hold back as much heat as the concrete Wall 1 itself. This is desirable because a window is a vulnerable point in a concrete building, when a combustible structure is burning closely adjacent thereto. By provision of the fireproof shutters, the concrete structure in which it is preferred the window assembly be used is made wholly iireproof so far as ring of said structure from an adjacent burning structure is concerned.

Referringr again to Figs. 2 and 3, immediately A above and below the window aperture I provide the spacers extending transversely across said aperture and disposed between and spacing apart the sash runs il, I8 and I9. These spacer members are each comprised of (see Fig. 3) opposed top and bottom channels 51 and 58 embracing the upper and lower longitudinal edges of a concrete bar S9 reinforced by wire mesh 5S.

The window stiles and rails may be constructed in several ways, but I prefer to use stock channels about {'-5 x 2 inches for stiles and top and bottom rails, and le X 11/2 inches for meeting rails with the open side inside to be covered by a steel plate, spot-welded or ibrazed or screwed on where it is necessary to remove plates for repairs.

Further, I believe it is also desirable to mention that the screen sash can be made similarly to the window sash and i-ireproof shutters, with a wooden core in the hollow space extending around the sash frame, to which core the screen may be tacked. A face plate ci the frame can then be screwed on, and this plate, whenever necessary, can be removed for the purpose of repairing screens.

What is claimed is:

In a window assembly for supporting upper and lower sashes in a Window opening having spaced vertical side walls, vertically spaced channel members secured to opposite vertical side Walls of the window opening, said channel members opening into the vwindow opening and defining Within and between them vertically spaced sash runways, a pair of spaced laterally inclined arms carried by each channel member adjacent the upper end thereof, said arms extending into the window opening, a pulley mounted in each pair of arms for rotation about a horizontal axis which lies parallel to the walls of the Window opening to cause diametrically opposed portions of the periphery of said pulley to lie midway between adjacent runways, sashes mounted in adjacent runways to move vertically in the window opening and cables trained over the pulleys and connected to the sashes to cause the sashes to move in unison and in opposite directions in the runways.
