' 2 Claims. (CI. 20-49) -This invention relates to window constructions of the double-hung type wherein the sash slide vertically with respect to the window frame. It pertains more particularly to a window construction wherein the sash may be moved pivotally with respect to the frame, in addition to their sliding movement, so as to provide for ventilation and also to dispose themso that the outside surfaces of the windows may be conveniently Washed.

The primary object of the invention is to provide a window construction of the character referred to wherein the upper and lower sash members are pivoted to elements slidable in the window frame, the sash and slidable elements having interlocking means rendering the joints therebetween weatherproof and also preventing pivoting of the sash members. outwardly of the frame while they are positioned for ordinary sliding movement.

Another object of the present invention is to provide manually releasable means for holding the sash members against pivotal movement inwardly of the frame when such movementis not desired, the means'being so constructed that it has a comparatively large area of contact with the window stops so as to eliminate possibility of forcing the window inwardly, either by wind pressure or bypersons attempting to gain. unauthorized entrance through the window into a building. In other words, the largeness of the bearing surface of the means referred to with respect to the window stops practically precludes the possibility of forcing the said means through. the window stops even though the latter are formed of comparatively narrow wood strips according to conventional practice. In addition to providing a large bearing surface the means referred to also provides for weatherproo-fing inasmuch as it closes spaces above the slidable members which otherwise would permit the entrance of air.

With the above and other ends in view the invention is more fully disclosed with reference to the accompanying drawings, in which Figs. 1, 2 and 3 are vertical sections illustrating different positions of adjustment of the sash members;

Fig. 4 is a fragmental section of the frame and sash;

Figs. 5 and 6 are top plans of the means for preventing the sash from pivoting;

Figs. 7 and 8 are elevations of said means, and

Fig. 9 is a fragmental section illustrating the sash pivot.

Like characters of reference are employed throughout to designate corresponding parts.

In-the drawings the numeral i designates a window frame having spaced stops 2 secured thereto and extending vertically thereof, each stop having a groove 3 extending throughout the length thereof. Slidable between the pairs of stops 2 are side rails 4, each side rail being formed of sheet metal and having a tongue 5 slidably received in the groove 3 of the adjacent stop 2, reference being had more particularly at this time to Fig. 4. From the tongue portion 5 the side rail has an integral portion which extends parallel to the inner face of the stop 2, as designated at 5, thus providing a surface for sliding engagement with the stop. The wall 6 as viewed 7 in. cross section terminates at the groove formation I, which is disposed inwardly of the inner surface of the stop 2, and a tongue formation 8 is provided at the inner side of the groove. The tongue formation 8 is supported by a wall 9 extending therefrom in the direction of the main body of the rail 4 which contacts with the inner surface of the frame member I. At the other side of the rail 4 a wall l extends inwardly of the window parallel toand in contact with the other stop 2 and the wall l0 supports a tongue l.

The sash member I 2 has a metallic member I 3 of substantially channel form secured thereto, the member l3 having a groove formation it normally receiving the tongue 8 and a tongue formation l5 normally received in the groove 1. At the other side of the sash [2 the member I3 has a groove formation It normally receiving the tongue ll.

Referring to Fig. 9, the metallic member l3 has a comparatively heavy metal reinforce l1 secured thereto, as by Weldinggand supporting a pivot pin I8. The pivot pin I8 is preferably in the form of a rivet. The lower end of the rail 4 has a protuberance formed inwardly thereof with a metal reinforce 20 secured thereto and receiving the other end of the rivet l8. Themembers 4 and I3 are thus pivotally connected together so that they may be relatively moved in order to permit movement of the sash to the various positions of adjustment illustrated in Figs. 1, 2 and 3.

Due to the interlocking engagement of the several tongues and grooves above described, the sash is prevented from being pivoted outwardly of the frame i. This interlocking engagement also provides for weatherproofing of the joint between the rails and sash. Additional weatherproofing is provided for by a channel member 22 which is nested within. the rail 4 in sliding engagement with the walls 9 and I thereof. Springs 23 normally press the channel-shaped sealing member 22 into engagement with the surface of the metallic member I3.

To restrict pivotal movement of the sash in.- wardly of the window to any desired extent links 24 are pivotally attached tothe sash and have pins 25 slidable in slots 26 in the channel members 22, a wall of each slot having a series of spaced notches 21 adapted to receive the pins 25. By engaging the pins in different notches the sash may be held. in an inclined position for ventilating purposes, such as shown in Fig. 2, a horizontal position for ventilating or washing purposes as shown in Fig. 3, or it may be held at different positions ranging between the two extremes illustrated.

Referring to Figs. to 8 inclusive, there is illustrated means for holding the members l3 against pivotal movement with respect to their rails l so that the sash may be moved vertically in the customary manner. This means comprises an angle bracket having a portion 28 secured to the top surface of the meeting rail 29 by screws or other fastening elements 30, and a portion 3| extending downwardly in contact with the outside surface of the sash member l2. At each side of the bracket portion 3| are formed hinge parts such as shown at 32 and plates 33 are hingedly connected to the bracket portion 3| by such hinge members. At the top of each plate 33 is a wall 34 formed with a slot 35 receiving a pin 36 on a head 31. The head 31 is connected to a sliding bolt 38 in such manner that the latter is free to rotate with respect thereto. The boit 38 is slidably received in the substantially cylindrical guide member 39 on the bracket portion 28. The guide 39 has a lengthwise extending slot 40 through which an actuating pin 4| extends, and one of the side walls of the slot is provided with notches 4'2 adapted to receive the pin 4| in such manner as to prevent the bolt from moving lengthwise with respect to its guide.

As illustrated in Figs. 5 and 7 the bolt 38 is in a position holding the plates 33 projecting from the sash and engaging adjacent stops 2. When so positioned the sash is free to move vertically of the frame but cannot pivot with respect thereto.

In Figs. 6 and 8 the bolt is in a position holding the plates 33 parallel to the edge of the shaft and removed from between the stops 2, and the sash is free to pivot with respect to the frame.

Although a specific embodiment of the invention has been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.

What I claim is:

1. In a window structure including a frame, a movable window sash, channel-shaped side members receiving side portions of said sash and having opposite surfaces disposed toward adjacent sides of the frame, each of said side members having a longitudinal groove between said surface and said frame along one vertical edge of the sash and having a second longitudinal groove along the other edge thereof, channel-shaped members interposed one between each of said first named channel shaped members and an adjoining side of the frame and closed by said surfaces, each of said second-named channel-shaped members having border portions of its opposite longitudinal edges positioned for sliding movement in said grooves.

2. In a window structure including a frame, a movable window sash, channel-shaped side members receiving side portions of said sash and having opposite surfaces disposed toward adjacent sides of the frame, each of said side members having a longitudinal groove between said surface and said frame along one vertical edge of the sash and having .a second longitudinal groove along the other edge thereof, channel-shaped members interposed one between each of said first named channel-shapedmembersand an adjoining side of the frame and closed by said surfaces, each of said second-named channel-shaped members having border portions of its opposite longitudinal edges positioned for sliding movement in said grooves, stop members, and side members each having a tongue along one edge thereof positioned in one of said grooves and having a tongue along the other edge thereof positioned for sliding movement in a groove in an adjoining stop member.
