The invention relates to folding metal windows and has for its object to provide a window of this character which is both air tight and moisture proof.

5 A further object is to provide a window 1n which the parts may be folded to the sides and permit of substantially the entire area of the terfering with the other half; it being cus-V tomary in windows of this type to have to vopen one side before the other half can be K moved. l A still further object is to provide a simple means for locking either half of the window in any desired position.

Still another object is to provide a means for automatically locking the windows in their closed position so that if the windows were closed and one forgot to operate the locking bolts they could not be opened from the outside.

Other advantages are indicated below. lo Referring to the accompanying drawings forming a part hereof and illustrating the invention:

Fig. 1 is an elevation looking at the inside of the window;

Fig. 2 is a sectional plan view with inter-- mediate parts broken out for economy of space, and showing the window in its closed position. The view is at line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1, showing 0 one half of the window fully opened and the other half partially opened;

Fig. 4 is a longitudinal sectional view on a larger scale through the frame and sash. The view is at line 4-4 of Fig. 1;

5 Fig. 5 is a fragmentary Vdetail sectional view showing the window locked in its full open position. This view is takenl on line 5-5 of Fig. 3;

Fig. 6 is a view similar to Fig. 5 showing 0 the window locked in its partially open position. This view is taken on line 6- 6 ofv Fig. 3.

Fig. 7 is a fragmentary elevation, the handle being in section, of one of the Cremorne bolts used for locking the window in different position. This view shows the Window locked in its closed position;

Fig. 8 is a fragmentar detail sectional view taken on line 8-8 of ig. 2; and

Figs. 9 and 10 are fragmentar detail sectional views of the snap bolts use for locking the window. These views are taken on line 9-9 and line 10-10, respectively, of F1g. 2. Referring again to the drawings, the reference numerals 11 designate the side members of the frame and 12 the upper and lower frame members.

Hinged at 13 to the side frame members are side sash members 14 of section 15 of the folding window. The side frame members 11 are provided with continuous ribs or flanges 16 which in the closed position ofthe window as shown in Fig. 2vcontact with the Sash members 14 and form an air tight and moisture proof joint.

The opposite side sash members 17 ofthe sections have hinged thereto at 18, on the interior side of the windows. side sash members 19 of sections 20 of the folding window. The hinges 18 are preferably continuous hinges from the top to the bottom lof the window. The side sash members 17 of the sections 15 are likewise provided with vcontinuous ribs or flanges 21 which cooperate with the side sash members 19 of the sections 20 so asto exclude air or moisture when the window is closed.

The other side sash members of the sections 20 are'designated 23 and 24 and act as the meeting rails when the Window is in its closed position. The side sash member 23 has a plurality of ribs or anges 25 which cooperate with suitable parts on the side sash members 24 to make the window air tight and moisture proof when in its closed position.

susv

The upper and lower frame members 12 are provided with cross members extending from side to side. These cross members 30 are secured in position by screws 31 or other suitable means and have continuous and lower sash members 33 of the sections 15 and 20, see Fig. 4, are provided witliribs or flanges 34 to cooperate with suitable parts on the upper and lower frame members.

Secured tothe upper and lower parts of the sections 20, lpreferably at the top and bottom of the meeting rails 23 and 24 are rollers or studs 36 which are slidably mounted in the tracks or guideways 32. The .tracks or guideways 32 areprovided with slight jogs 37 (see Fig. 3) at their central portion so as to give the meeting rail 24 a slight outward movement just prior to it contacting with the rail 23 and insure against any possible interference.

It will be apparent from the foregoing description an'd an inspection of the drawings that both halves of the folding window may be readily thrown to the position indicated in the left hand part of Fig. 3 and that .s a maximum window opening without any obstructions whatever will be obtained. It will also be apparent that either half of the window may be opened at will without interfering with the other half. It will also be apparent that a simple construction is provided which is both air tight and moisture proof when the window is in its closed position.

The means for locking the window in its closed or any other desired position will now be described.

Mounted on the meeting rails 23 and 24 on the interior side of the window are Cremorne bolts 40, particularly illustrated in Figs. 7 and 8. The Cremorne bolts comprise two slides 41 and 42 which enter housings 43 secured to the meeting rails. These slides are moved simultaneously upward and downward by the rotation of a handle 44. When the windows are in their closed position and it is desired to lock them there the handles 44 are pulled downward, the ends of the slides 41 and 42 move behind keepers 45 and the window is locked so that it cannot be opened from the outside and will not vibrate due to the wind.

When either half of the window is fully opened or partially opened, a slight downward pull on the handles 44 will force the ends of the slides 41 and 42 against the cross members 30 and positively lock the windows in any desired position. In Fig. 5 the parts are shown in the position they would assume with the windows locked fully open and in Fig. 6 with the windows locked in a partially open position.

Automatic locking means are provided at the juncture of the sections 15 and 20. This automatic locking means comprises snap bolts 50, particularly shown in Figs. 9 and 10. These snap bolts are mounted iii the side sash members 19 of the sections 20. These comprise housings 51 having bolts 52 @.XQDCling upwardly and downwardly. These bolts are beveled at their ends 54 and are spring pressed in a locking position by springs 55. When the window is pulled closed the ends of the bolts will latch past the lower frame members and enter openings 56. A handle 57 operates a cam mechanism 58 so that when it is desired to open the window the handle 57 is manipulated, the snap bolts are Withdrawn and the window pushed open.

It will be plain from the foregoing if the window were closed and the Cremorne bolts weie not locked, the snap bolts would spring in place and prevent the window from being tampered with from the outside. It will likewise be apparent from the foregoing that the window may be easily and quickly locked in any desired position.

Pull handles 60 are secured to the sash members 19 to facilitate the closing of the windows. The glass 61 may be secured in the sash members in any well known manner.

Considering Figs. 2 and3, it is noted that there are two pairs of folding window-sashes, the members of each of which pair are indicated by 15 and 20, at each side of the central meeting rails. Each sash 15 is hinged to a vertical frame member 11 at 13 so as to swing outwardly. The inward vertical edged portion of each sash 15 has hinged to it at 18 a sash 20, the hinged spindle of hinge 18 being on the inward side of each pair so that each sash 20 may be swung inwardly and brought up against the outwardly swung sash 15 when the two sashes are in fully open position. The hinged edge of each sash 15 is provided with the fiat extruded ribs 16 and the hinged inner vertical wall of each vertical j amb 11 is provided with corresponding flat extruded flanges. When either or both sashes 15 are j closed, these extruded ribs abut to form weathertight joints. The opposed hinged edges of each pair of sashes 15 and 20 are similarly provided with extruded metal ribs that form complementary weatliertight abutments, when the two sashes are in alignment 1n closed position.

The inward free vertical edges of the frames of the two sashes 20 are similarly provided with extruded joint-forming ribs as above noted and these ribs coming into cooprative contact, when the window is closed, form weathertight joints for the latter mentioned sash members which form the vertical 1 meeting rails. It has been pointed out that in the opening and closing movements of each pair of sashes 15 and 20, the sash are guided at top and bottom by abutments extending either into an upper track groove or an under track groove 32; there being an upper and an under track groove and each sash 20 being provided with an upper and under roller or stud 36 which work in the track 32.

Each track is horizontally disposed and ex- I tends lengthwise of a top or bottom frame casing member, as the case may be.

It is an important feature of this invention to provide for the opening of either pair of sash by a push on the handle 60 in the outward direction. (See right hand of Fig. In such movement the extruded ribs on the inward edge of the right hand meeting rail or member 24 is initially withdrawn by a very slight angular movement from its Contact with the complementary extruded ribs on the opposed meeting rail. On the other hand, an outward push on the handle 60 of the left hand pair of sash 15 and 20 would similarly withdraw at a slight starting angle the eX- truded ribs on the vertical edge of the left hand meeting rail, leaving the right hand pair of sash in closed position. The slight )ogs 37 referred to aid in securing the desired slightly angular withdrawing movement of f one set of these extruded ribs from contact with the other.

The automatic locking devices including the snap bolts 50 are located for each pair of hingedly connected sashes 15 and 20 in the outward edge portion of an inward sash 20. These bolts automatically snap into locking position (Fig. 10) and when either pair of hingedtogether sashes are brought into aligned closed position, that pair of sash is automatically locked in position; and even if the Cremorne locking devices of the meeting rails are not moved into locked position, one or both pairs of the hinged-together sashes 15 and 20 are certainly locked in closed position.

Referring to Fig. 4, it is noted that the upper and under members containing the tracks 32 are detaehably secured in place. These members are indicated by 30 and are made detachable because when the track walls become worn, themembers may be replaced. They also reinforce the adjacent window or doorway frame members. It is here noted that while the invention above described is referred to as an improvement in windows, such Windows may be long doors with either glass` or solid panels.

Various changes may be made in the details A invention. The members referred to as sash are in reality structures Which may be win.- dow or door frames oftransparent or solid material an d made of glazed Windows or shutters r otherwise, as desired.

` What I claim is:

The combination with a stationary metal trarne having upper, under and vertical side edges; and the opposable vertical edges of the inner frames being eontactible, one with the other, when in aligned position; the members of each pair of frames being swingable into an outside iiatwise, folded position; upppr and under lengthwise-extending straig t, metal,`lengthwise channeled guide tracks and metal, frame-carried studs projecting into the channels of the guide tracks and cooperating with walls thereof during the opening and closing movements of the frame; and an automatic locking device for each pair of frames said guide tracks being detachably secured each to a stationary frame jamb and also serving as a lengthwise and Widthwise reinforcementl thereof; side walls of the guide tracks being laterally jogged midway between their ends for lateral movements of cooperating studs to secure joint-forming Contact without interference of the opposable edges of the innermost movable frames.
