WINDOW CONSTRUCTION.

Application fil ed August 18, 1928. Serial No. 300,593.

This invention relates to window sashes and more particularly to a novel and improved mounting for the sash proper whereby it may be swung or rotated on a horizontal axis for the purpose of cleaning the window.

One of the objects of my invention is to construct a window sash having provision for allowing a swinging movement of the upper or lower sash on a horizontal axis pivot thus permitting the outside surface and sash of the window to be cleaned from the inside of a room.

A further object of my invention is to construct a sectional window sash operable in the usual guides of a window frame, one of said sections being rotatable on a horizontal axis so as to be swung relative to the second section at different positions in the window frame.

A continued object of my invention is to provide a top and bottom window sash 0perable in the usual guides of a window frame, including provision for partially rotating the upper and lower sashes on horizontal pivots relative to the said frame so as to per-,

mit of ventilation in a room.

To enable others skilled in the art to more fully comprehend the underlying features of my invention, reference is had to the accompanying drawing forming a part of this specification in which- Fig. 1 is a front view showing my invention.

Fig. 2 is a vertical sectional view, the bottom window frame being shown in dotted lines in one of its positions.

Fig. 3 is a vertical sectional view showing the top window frame when lowered and in dotted lines illustrating one of its positions.

4 Fig. 4c is an enlargedsectional view showing the locking means in the window frame proper.

Fig. 5 is a cross sectional view through the locking means.

Fig. 6 is a cross sectional view through one of the pivots.

Fig. 7 is a view partly in section showing the position of the adjusting roller.

Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views,

5 designates the inside frame and 6 the outside strips of the frame of a window sash having the usual pane of glass 7. The top and bottom window sashes are similar in construction and consequently a description of one sash only will be necessary for a complete understanding of my invention. The top and bottom sashes are adapted to be positioned in the usual frame of a building having vertical guides. The said sashes and frame may be of metal or of wood.

Referring particularly to Figs. 4i and 6, it will be noted that the inside frame 5 is provided with a recess or opening 8 extending from top to bottom and that the outside strips 6 with similar recesses or openings 9 directly opposite thereto. The recess or open ing 8 is considerably deeper than the recesses or openings 9 for a purpose presently to appear. 1

Located within the recesses 8, 9 for horizontal sliding movement'therein, I provide a locking channel bar 10 substantially U- ,shaped in cross section and extending from the top to the bottom of each sash. The locking channel baris of a depth to bridge the space between the inside frame and the outside strips andlock the two sections together in one position, as shown for instance in Fig. 4, and in which position, the sash may be moved up and down in the frame guides. The channel bar, however, is adapted to be moved inwardlyto thedotted line position, as shown in said figure, in order to clear the recesses or openings 9 and thus permit the inside frame to move or rotate relative tothe outside strips. In order to accomplish this operation, the inner side or wall 11 of the locking channel bar has permanently attached thereto the head 12 of a screw bolt 13 which is movable in a sleeve 14 extending horizontally and partially through the frame. The threaded portion of the bolt 13 meshes with an internally threaded knurled roller 15 rotatable on the sleeve 14, said roller extending into acurved recess or opening 16 in the frame. Consequently by rotating the roller and advancing the threaded bolt, the locking channel bar-10 may be moved to the left or to the right to its locked or released position. When in the released position, said inside frame may be rotated relative to the outside strips in the following manner.

Substantially intermediate the top and bottom of each sash and at each side thereof, I provide a pivot bolt 16 held in a sleeve or bushing 17, said bolt and sleeve extending through an opening in the wall or side 11 of the locking channel bar. The head 17 of said pivot bolt engages the inner end of the sleeve or bushi g l and n he ter nd f id pivot bolt is a countersunk lock nut 18. The inner frame may thus swing on the pivot bolt when the locking channel bar is released from the outside strips.

From the above construction, it will be seen that I have provided a sash that may be swung on a horizontal axis so that access to the out-side of the sash may be had for the purpose of cleaning the window and the sash proper if so desired from the inside of a room. For instance, in Fig. 2 I have shown the bottom sash in dotted lines, in one of its positions, and in Fig. 3 the top sash, when lowered, is shown also in dotted lines, in a second position. Under ordinary c0nditions, the sashes are rotated for cleaning purposes when in their lowered positions, but it will also be seen that if so desired, both the top and bottom sashes may be partially rotated when lowered and raised'when it is desired to ventilate the room permitting the foul air to leave through the top and the fresh air to enter through the bottom.

While I have shown and described my invention with some degree of particularity, it

will be realized that other modifications and changes maybe resorted to under special conditions. I therefore do not wish to be limited and restricted to the exact details shown and described but reserve the right to make such changes and modifications as may fairly fall within the scope of the subject matter now being claimed.

Having shown and described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A sash of the class described comprising an inner frame having outer strips adapted to slide in the guides of a window frame, said frame having; deep recesses in the sides thereof, said strips having recesses therein ,seo

opposite to the first mentioned recesses, a

channel bar movable from a locked to a released position in said recesses, threaded means for actuating said channel bar to release the said frame from the said strips in one position, and pivot bolts extending through the said channel bars and connecting the frame with the strips whereby said frame may be rotated when the channel bars are in their released positions.

2. A sash of the class described comprising; an inner frame having outer strips adapted to slide in the guides of a window frame, said frame and strips having outer and inner opposed recesses and a locking channel bar located therein, a threaded element connected to each of said channel bars, an internally threaded roller cooperating with said element for advancing said bar from a locked to a released position whereby said frame may be moved relative to the strips and pivot bolts connecting the frame and strips whereby said frame may be rotated.

3. A sash of the class described comprising an inner frame having outer strips adapted to slide in the guides of a window frame, said frame and strips having opposed recesses extending from the top to the bottom thereof, U-shaped channel bars in the recesses and at the sides of said sash, a threaded element attached to the inner wall of said bar, a sleeve for said element, a roller cooperating with said threaded element and located in a recess in the front side of said inner frame and pivot bolts connecting the said frame with the outer strips whereby said frame may be rotated when the channel bars are in their released positions. 1

In testimony whereof I affix my signature.
