REVERSIBLE WINDOW.

Application filed July 9, 1917.

To all whom it may concern Be it known that I, NICHOLAS M. STARQK, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Reversible Windows; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in slidable window sashes, particularly those which are pivoted to swing out of alinenient with the window frame.

It is primarily an object of this invention to provide means whereby wind-ow sashes may be pivotally as well as slidably mounted in a window frame for permitting ready access to both the inside and outside of the panes thereof. This provision allows both the inside and outside of the window sashes to be cleaned from the inside of the room.

In carrying out this principal object, minor objects of the invention consist in an improved sliding connection between the sashes and the adjacent portions of the window frame; any means for normally retain-' ing the sashes in vertical position and against accidental movement out of alinement with the frame; and any means for retaining the sashes in different positions when moved out of alinement with the frame.

vVltl'l the foregoing objects and advantages in view the invention resides in th novel features of construction combination and arrangement of parts which will be hereinafter more particularly described and claimed, and shown in the accompanying drawings wherein:

Figure 1 represents an upper left hand corner of a window frame showing the portion of an upper sash therein, parts of the frame and sash being broken away and shown in section to more clearly illustrate certain features of theinvention.

Figs. 2 and 3 are horizontal sections taken substantially on the planes of the lines 2-2 and 33 of Fig. 1.

Fig. 4 is a vertical sectional view through a window frame showing the manner in which the sashes thereof may be swung to certain positions.

In the illustrated embodiment of my invention, it will be noted that the improvements Specification of Letters Patent.

are applied to ordinary wooden sashes and frames. It is obvious, however, that the same arrangement could be also used with all metal frames and window sashes with only slight modifications. It will also be apparent that the invention be applied to ordinary windows already in use as well as those which are just being constructed.

The frame 1 is of ordinary construction, it being provided with the usual weight box 2 and the exposed portions which are covered by a trim of any preferred design. The frame is also designed to receive upper and lower sashes 3 and @i respectively which slide vertically in channels formed in the opposite side walls of the frame by means of the outer strips 5 of trim material and the head 6.

In order to apply my invention, it is necessary that the sashes 3 and i be somewhat narrower than the usual sashes provided for standard size frames, inasmuch as the improvements are disposed between the side walls of the frames and the adjacent side edges of the sashes. The opposite side edges of the sashes have a substantially H-shaped sheet metal strip 7 disposed thereover, the arms 8 of the strip being engaged with the inner and outer sides of the sashes to which they are secured by screws or the like 9. The arms or flanges 10 of the strip 7 are disposed substantially in alinement with the arms 8 and project beyond the edges of the sashes as clearly shown in Figs. 2 and 3. They may be formed in any desired manner, but are preferably constructed in the manner shown that is to say, by bending the strip longitudinally upon itself adjacent to its longitudinal edges. This is also most desirable, inasmuch as the strip is of light sheet metal.

The arms or flanges 10 being disposed longitudinally throughout the length of the sashes form one part of cooperating guides for movable contact plates 11, one of which is disposed on each side edge of each sash. These plates are, also, in the form of strips of sheet metal, they being preferably longitudinally concaved with their outer edges bent laterally as at 11 for engagement with the outer surfaces of the flanges 10. Substantially U-shaped reinforcing plates 12 are disposed between the contact plates and the adjacent members 7 and the laterally bent edges 13 thereof are spaced from the similar portions of the contact plates and are designed toengage the inner surfaces of the flanges 10.

Expansion coil springs 14 are also disposed between the contact plates 11 and the adjacent edges of the sashes, whereby the former will be continually urged outwardly away from said sashes. The combination of these springs, however, will be overcome by pressure on the contact plates so that the latter will be enabled to be moved inwardly, and during both inward and outward movement they will be guided by the guides formed by the flanges 10, 11 and 13.

Positioned between these parts and the adjacent walls of the frame are carriages 15, which are substantially U-shaped, the distance between their arms 16 being approximately the width of the channels formed between the strips 5 and 6. These carriages are each of a length substantially equal to the height of the sash with which it is used and are provided with rollers 17 for sliding contact with the frame. To form bearings for the rollers, the arms 16 of the carriages are bent laterally inwardly and then toward the outer face thereof, as shown at 18. Said outer faces of the carriages are longitudinally convexed and are adapted to engage with the concave faces of the contact plates 11. I

Each sash has a pivot stud 19 extending from its opposite side edges substantially midway the length thereof, said studs being projected through the contact plates 11, the reinforcing plates 12, and the convex faces of the carriages, thereby pivotally mounting said sashes to the adjacent carriages. Since the springs 14 will normally urge the contact plates outwardly, it is obvious that there will be considerable frictional engagement between said plates and the carriages so that a pivotal movement of the sashes will be re stricted, thus preventing accidental movement of said sashes. They may readily be slid vertically in the frame, however, and retained in any position therein by the usual counter-balancing weights disposed in the weight boxes 2, the sash cords 20 for these weights being drawn over pulleys 21 and secured to the carriers by means of cross strips 22 each connecting the portions 18 thereof.

In order to dispose the inside of one of the window sashes inwardly to clean it, or for any other purpose, it is swung about the pivot studs thereof, as shown by the dot and dash lines in Fig. 4. Because of the frictional engagement between the contact plates and the carriages, the sashes may be main- Gopies of this patent may be obtained for tained practically in any angular position relative to the frame. Furthermore, it is also obvious that since the pivotal connections between the sashes and the frame are movable, said sashes may be reversed regardless of their position in the frame. Also, said sashes may be slid vertially inthe frame after or during pivotal movement thereof, as well as before.

I claim:

The combination with a frame and a window sash or the like disposed therein, of means of mounting the window sash or the like for sliding and rotative movement in the frame comprising a plate substantially H shaped in cross section, the longitudinal flanges extending from one side of the plate being secured to the inner and outer sides of the sash or the like at one edge, the longitudinal flanges extending from the other side forming one part of cooperating guides, a movable contact plate longitudinally concaved and having its longitudinal edgesbent laterally for sliding engagement with the outer surface of the guide flanges of the H-shaped plate, a reinforcing plate substantially U-shaped in cross section and disposed between the H-shaped plate and contact plate, said reinforcing plate having its flanges engaged with the inner surface of said contact plate and spaced from the flanges thereof to slidably receive the guide flanges of the H-shaped plate therebetween, a carriage U-shaped in cross section disposed between said contact plate and the adjacent wall. of the frame, the face of the carriage being longitudinally convexed for engagement with the concave face of the contact plate, a pintle extending from the H-shaped plate and slidably disposed through the reinforcing plate and contact plate, said pintle being journaled in the convex face of the carriage, a pair of expansion springs positioned between the reinforcing and the H shaped plates and disposed one on each side of the pintle, roller bearings formed on the carriage by bendinnithe flanges the eof latorally inwardly and then toward the outer face thereof, rollers disposed in said bearings for sliding contact with one wall of the frame, and sliding pivotal connection be tween the other wall of the frame and the p glzjacent edge of the window sash or the In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
