SPECIFICATION forming part of Letters'Patent No. 499,236, dated June 13, 1893.

y Application tiled January 28, 1893. Serial No. 460,452. (No model.)

To all whom it may concern:

Be it known that I, JOHN LEWIS, a subject of the Queen of Holland, and a resident of New York, in the county and State of New York, haveinvented certain new and .useful Improvements in Windows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, lnakinga part of this specilication.

This invention relates to windows of that class wherein the sashes are arranged not only to slide vertically but to swing on horizontal pivots so that the outside of each sash may be turned in readily for purposes of cleaning and so forth or so that the sashes may be turned edgewise to remove obstruction to the free passage of air.

The object is to simplifyv the construction so as to reduce the cost and to diminish the liability to get out of order, and to make the entire removal of either or both sashes a matter of ease. l

The invention consists in the construction hereinafter described and claimed.

In the drawings: Figure l is a perspective view of awindow-frame and sashes having my improvement-s applied. Fig. 2 is a vertical section on the line oc-:c of Fig. l, showing both sashes in their normalpositions. Fig. 3 is a similar section but showing both sashes raised as far as possible. Fig. 4. is likewise a similar section but showing .the hinged portion of one side of the frame swung outwardly to permit access to the sash weights or preparatory to swinging one or both of the sashes. Fig. 5 is a section on the line y-y of Fig. 2. Fig. 6 is a partial horizontal section on the line z-z of Fig. 1. Fig. 7 is a similar section but showing the hinged portion aforesaid swung outwardly as in Fig. 4, and the lower sash turned on its pivots.

The window-frame A is for the most part of ordinaryconstructionfand is provided as usual with sash pulleys B, B, over which pass the sash-cords C, C, attached to the sashes and to the weights D, D. The recess cabove the upper sashE is somewhat deeper than usual so as to permit the sash to be pushed up far enough to clear its lower rail from the upper rail of the lower sash F. Above the middle line the sides d', d', of the frame may be formed, as usual, with parting strips a2 and guard strips as, a4. Below the middle line, however, the parting strip a2 and the guard strips CL3, a4, on each side are secured to or are formed by grooves in a board or plate d5 which is hinged at one edge to the side d of the frame, and may be provided at the other edge with a catch or other fastening device 0.6. Each side of the frame is cut open, as at al, so that the board or plate a? becomes a door which can be opened easily to give access to the sash weights D, D. Above the opening of each side of the frame is formed with a groove or grooves d8, a8, which are entirely covered when the plate a5 is in its normal position. The grooves a8 may be extended aboveA the middle, as indicated in Fig. 2,-but it is not necessary. The side bars of each sash are perforated at about the middle to receive pins e and f, as shown, which are movable longitudinally and are provided each with a suitable lknob orv handle e and with a head e2 to which the sash-cord is attached.

Normally the boards or plates d5, a5, are closed against the sides of the frame and the 'sashes areyfree to slide up and down as usual without turning. When, however, it is desired to turnor swing either sash upon its pivots both sashes are first pushed up as far as possible and the boards or plates a5, a5, are

swung outwardly, as shown'in Figs. 4. and 7.

The sash to be turned is then drawn down and its pins e, e, or f,f, are pushed in so that their inner ends enter the grooves as. When the sash has been pushed down as far as possible the pins aforesaid rest upon a stop-plate a. and the sash may then be turned upon the pins as pivots. If it is desired to remove the sash entirely the pins are drawn ont of the grooves and the sash can then be taken out bodily. Both sashes can be drawn down and swung or turned together, if it is desired to remove all obstructions to the circulation of air, the upper sash in this case resting to some extent upon the lower as the two are turned.

' Y I am aware that many constructions have been devised to permittheswingingofwindowsashes, but all of these constructions are too expensive, too complicated, too cumbersome and too apt to get out of order to permitthem IOO to come into general use. My improved construction can be operated at all times without dimculty, has no part-s to be broken easily, and adds but little to the cost of an ordinary Window-frame.

I claim as my invention- 1. A window-frame having its sides grooved and plates to cover said grooves and carrying on their outer faces the parting strips and guard strips, in combination with a sash having in its side-bars horizontally movable pins which can be pushed in to engage said grooves, substantially as shown and'described.

2. A window-frame having its sides grooved, a stop plate forthe lower ends ot' said grooves, and plates to cover said grooves and carrying ou their outer faces parting strips and guard strips, in combination with a sash having in its side-bars horizontally movable pins which can be pushed in to engage said grooves, substantially as shown and described.

3. A Window-frame having its sides grooved, plates hinged to the sides of said frame to cover said grooves and carrying on their outer faces parting strips and guard strips, and

catches to hold said plates in position,in combination with a sash having in its side-bars horizontally movable pins which can be pushed in to engage said grooves, substantially as shown and described.

4. A Window-frame having a deep recess above the upper sash to permit the same to be pushed above the middle line of the frame and having its sides grooved below the middle line, plates hinged to the sides of the frame below the middle line to cover said grooves and carrying on their outer faces parting strips-and guard strips, in combination with upper and lower sashes having in their side-bars horizontally movable pins which can be pushed in to engage said grooves, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
