Application filed June 4, 1912.

To all whom it may concern Be it known that I, CHARLES Coormn, a citizen of the United States, residing at No. 322 Fifty-sixth street, Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Window-Sashes, of which the following is a specification.

This invention relates to window sashes and especially to that class in which the sashes may be reversed so that repairs may be made or the windows easily cleaned ""om either side and it consists of a new and novel arrangement of metal strips carried by the sashes on both sides and which retain the sashes in their operative position or which may be so adjusted as to disconnect the sashes from the guiding strips so that they may be rotated on a pivot carried by the metallic strips as will be more fully described in the following specification, set forth in the claim and illustrated in the drawings, wherein Figure 1 is a view of a window showing the improved sashes applied thereto. Fig. 2 is a side view of the window frame with the sashes tilted. Fig. 3 is across sectional view through the two sashes showing the strips adjusted to different positions. Fig. 4 is a detail sectional view. Fig. 5 is a view of the key for changing the position of the strips.

The invention maybe applied to any ordinary window sash of the usual construction but the sash grooves are dispensed with and the stop beads are separated to form channels 11 in connection with the parting head 12. The sashes 13 may be of the usual form and have the meeting rail 14: as usual, while the pulley stiles 15 are provided to house the weights 16.

The channels 11 are provided for the reception of metallic strips 17 formed, as will be seen, in cross section, with three sides and carrying about midway between their ends the block 18 having in its upper end the hook 19 for the sash cord and a pivot 20 which projects through the opening 22 at the side rail of the sash. The pivot 20 is provided with a threaded end with which a detachable head 21 may be engaged for Specification of Letters Patent.

holding the pivot in a retracted position as shown at the lower portion of Fig. 3.

Along part of its length the pivot 20 is formed with teeth 23 which may be engaged by the pinion 24 at the end of a key 25 and the object of these teeth and the key is to move the pivot longitudinally and to Work the strip 17 in or out so that it may occupy the position shown in connection with the upper sash in Fig 3 and where the strip is shown as being entirely within the channels 11, thus permitting the sash to clear it and revolve on the pivot 20 but where it is desired to retain the sash in its operative position so as to slide up or down, the pivot 20 is retracted so that the strip occu ies the position shown in the lower sash 0 Fig. 3 when the sash is obliged to retain its vertical position and is capable of sliding along the stop bead 10 and the parting head 12. The sash cord is attached at one end to the hook 19 and passes over the pulleys and is attached at its other end to the weight.

The herein described structure forms a simple and substantial device for permitting the rotation of the window sash within the frame; but such structure in nowise detracts from the efficiency of the sash in point of preventing the entrance of a perceptible amount of air into the room when the said sash is closed and the parts adjusted to admit of its being used as an ordinary sash, this air-excluding feature, of course, residing in the strips 17 and the provision of the opposed channels for receiving these strips.

What I claim as new is In combination with a frame and a sash each having a channel, the said channels being of the same transverse width, the channel in the frame being deeper than the channel in the sash, a strip U-shaped in transverse section arranged to slide in the channel of the frame and adapted to be completely received therein, the said strip also being adapted to be moved and partially received in the channel of the sash, a block held between the opposite side portions of the strip at a point between the ends thereof, a counter balance connected with the block, a bolt attached to the block and passing through the intermediate hortioxi of the strip and pivoted in the side of. thesash, and.

passing completely through thew'sameysaid bolt being movable longitudinally 1n the sash, and ahead mounted on the bolt and adapted to bear against the inner surface of the side of the sash.

In testimony whereof I have affixed my signature in presence of two witnesses.
