UNITED STATES? WILLIAM B. eA'rEs'oE WILKINSBURG, PENNSYLVANIA.

REVERSIBLE wmnowl Application filed. August 24, 1923.

This invention relates to a reversible window construction and particularly to a'pivot therefor.

The invention has for one of its primary objectsto provide a new and useful pivot for reversible windows.

A further object of the invention is to provide, in combination with a reversible window, reversible strips and a pivot construction designed to carry the weight of the sash on the frame instead of the reversible strips.

The invention may be readily understood by reference to the accompanying drawings, in which:

Fig. 1 repersents a side elevation of 'a pair ofrever'sible windows in a frame;

Fig. 2 shows, on a larger scale, a transverse section through one side of a sash and frame at the pivot;

Fig. 3 is a transverse section in the plane of line III-1110f Fig. 1, but on a larger scale;

Fig. 4 is a section of the pivot in the plane of line IV-IV of Fig. 2; and

Fig. 5 is a front view of one of the members of the pivot for the window.

Fig. 6 is a modificationshowing a pivot for a vertically pivoted window.

In the drawing, 5 represents the side of a window frame and 6 designates the two sashes. Extending down'the side edges of each sash is a longitudinal groove 6 Inset in each side edge of each sash at its middle is a metalplate 7 having a square hole or socket 8 in its center and having a recess 9 therein which'is in line with and conforms to thegroove 6 in the sash.

Interposed between the side edges of the sash and the frame in the usual manner, one at each side of the sash, is the reversible strip 10. These strips are substantially wedge shaped, beingwider along one edge than the other, the inside corner 11 of the thicker edge bearing against the frame.

This arrangement permits the strips to rock. On each strip is a longitudmal rib 12 which is disposed nearest the thinner edge of the strip. These ribs are adapted to fit into the respective grooves 6 of the sashes with which they cooperate. The strips. as shown in Fig. 1, are co-extensive with the length of the sash against which they are fitted, the strips for the upper sashes overlapping those for the lower sashes, as shown in Figs. 1 and 3.

Serial No. 659,038.

On the inner face of each reversible weather strip is a resilient metal weather striplB. Ineach reversible strip is a hole 14, enlarged at 15, this hole being located opposite the square hole 8 of the plate 7 in the part of the sash with which the respective strips cooperate.

Secured to the frame at the proper points are metal plates 16 on each of which is a stud 17. Radiating from each stud are a plurality of grooves 18. Fitted over the stud, and rotatable thereon, is a trunnion member 18 having a head 19 on which are two diametrically opposite teeth 19 adapted to engage in the grooves 18. The trunnion extends through hole 14 and has a squared end 20 adapted to fit into socket 8 in plate 7.

The metal plates 16 may be secured to the frame by screws 21 or other suitable fastening means passed through an ofi set extension at the side of each of the plates. Embracing the trunnion 18 and confined in the enlarged opening 15 in the strip is a compression spring 19 which urges the teeth 19 into the grooves 18.

In operation, when the windows are closed: the ribs on the reversible strips are received in the grooves of the sashes. WVhen one of the windows is swung open, the rib is forced out of the groove, rocking the strips inwardly on edge or corner 11. The swinging movement of the window imparts a rotary motion to trunnions 18. When the window is swung out at the'desired angle, ribs 19 will be forced into grooves 18, to hold the window against movement. These cooperating teeth and groove in effect form a ratchet.

The reversible strips may be secured in place by screws at opposite ends, passing through loose holes inthe strips and engaging in the frame, each screw being indicated at 22. The hole 14 is large enough to permit of the strip being rocked without binding, on the trunnions.

\Vith this arrangement, a holding ratchet is provided for the windows, while the weight of the sashes is supported directly on the frame.

In the modification shown in Fig. 6, a pivot is shown for a vertically pivoted win dow. This pivot includes a plate 23 having a stud 24, about which are radially arranged notches 25. This plate is secured to the bottom of the frame.

Secured to the bottom of the sash is a co operating plate 26 in which is a hole to receive stud This plate has ribs 27 for engagement in the notches 25. The weight of the window tends to normally hold the cooperating teeth and grooves of these members in engagement with each other, but by applying suiiicient p essure, the window may be swung, stud 2 1 acting as the bottom pivot. Any suitable pivot, not shown, may be provided for the top of the sash, also not shown.

I claim as my invention:

1. The combination with a sash, a frame and a reversible strip interposed between the sash and frame, said strip having a projection entered in the sash and being movable relatively thereto, of means for pivoting the sash in the frame comprising cooperating members on the sash and frame, one of said members projecting through the strip and having a socket therein, and a stud on one of the members entered in the said socket.

2. The combination with a sash and a frame and a reversible apertured strip interposed between the sash and the frame, of means for pivoting the sash in the frame comprising cooperating members on the sash and frame, one of the members passing through the aperture of the reversible strip, one of the members having a stud thereon and the other member having a socket for receiving the stud, and a spring in said a )erture.

The combination with a sash and a frame and a reversible apertured strip interposed between the sash and the frame, of means for pivoting the sash in the frame comprising cooperating members on the sash and frame, one of the members passing through the aperture of the reversible strip, one of the members having a stud. thereon and the other member having a socket for receiving the stud, and teeth on one of the members yieldably engaged in grooves provided on the other member.

4. The combination with a window frame, a sash, and a recessed reversible strip between the frame and sash, of means for pivotally supporting the sash on the frame and for holding it in various positions to which the sash may be turned, said means including a trunnion engaging the sash and rotatable therewith, said trunnion extending through the strip, a stud member on the frame on which the trunnion rotates, a spring in said recess surrounding the trunnion, and cooperating grooves and teeth on the trunnion and stud member.

5. The combination with a window frame, a sash, and a recessed reversible strip between the frame and sash, of means for pivotally supporting the sash on the frame and for holding it in various posit-ions to which the sash may be turned, said means including a trunnion engaging the sash and rotatable therewith, said trunnion extending through the strip, a stud member on the frame on which the trunnion rotates, cooperating grooves and teeth on the trunnion and stud member, and a spring in the recess of the strip and disposed around the trunnion and confined between the stud engaging end of the trunnion and the strip for yieldably urging the trunnion toward the stud.

(3. The combination with window frame, a sash, and a reversible strip between the frame and sash, of means for pivotally supporting the on the frame and for holding it in various positions to which the sash may be turned, said means including a plate on the sash having a square hole therein, a trunnion member passing through the reversible strip and having a square inner end engaging the hole in said plate, a head on the opposite end of the trunnion, a spring around the trunnion received in a recess in the reversible strip for urging the trunnion outwardly, said trunnion having an axial hole in said head, a plate secured to the frame, a stud on said plate extending into the hole in the head of the trunnion and providing a bearing for the trunnion, said stud carrying plate having notches therein, and means on the end of the head of said trunnion for engagement in the notches.

In testimony whereof I affix my signature.
