WINDOW.

SPECIFICATION forming part of Letters Patent No. 557,653, dated April '7, 1896.

Application filed November '7, 1893. Serial No. 490,271. (No model.)

To (oZZ whom it may concern.-

Be it known that 1, WILLIAM H. DEAN, a citizen of the United States, residing at 'est Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in lVindows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement on the window shown and described in my application filed June 15, 1892, bearing Serial No. 6,772; and the object of the same is to so construct the sashes as to make them have the appearance as nearly as possible of the ordinary sash and to bring them together at the central portion thereof and also to permit the bottom sash to be flush with the top of the frame.

A further object of the invention is to apply attachments and convenient devices to the window which will render it more efficient in operation and use.

With these and other objects in view the invention consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a window embodying the improved invention. Fig. 2 is a longitudinal vertical section of the same.

Similar numerals and letters of reference indicate corresponding parts in both views.

Referring to the above figures, the numeral 1 designates the upper sash, and 2 the lower sash, each of which is composed of an outer or sliding frame and an inner or swinging sash 7, the latter bearing the glass and being hinged to the former by means of the hinges C, which enable it to be swung within the room to facilitate the cleansing of the glass. The swinging sashes 7 and sliding frames are rabbeted on all four sides to enable them to come flush when closed, as well as to form a barrier to the entrance of drafts or moisture. The swinging and sliding sashes are retained in a closed position by means of the sliding locks or bolts 18, one at the upper and the other at the lower corner of each of the swinging sashes 7, opposite the side bearing the hinges C, the object of two locks on each sash being to more successfully resist any pressure tending inward, such as that caused by heavy winds, and further to prevent disagreeable rattling.

In order to enable the lower sash 2 to go flush with the top of the stationary frame, I have caused the ordinary guide-strip & to be positioned slightly back of the side guidestrips 5. The object of having the lower sash 2 go up as far as possible is to allow the upper sash 1 when lowered to swing inward on the hinges 0 clear of the lower rail of the lower sash 2.

A rabbet 3 is formed in the upper rail of the top sash 1 to receive the cross guide-strip at as the top sash is forced upward against the stationary frame.

On the under surface of the top rail of the lower sash 2 is formed a rabbet similar to one on the upper surface of the bottom rail of the upper sash 1, and between which rabbets is positioned a stationary bar 6, the ends of which extend into the side guide-strips 5, the object of the bar 6 being to prevent flies or other insects from entering between the top rail of the upper sash 1 and the bottom rail of the lower sash 2 when the sashes are in the position adapted for opening or swinging inward the inner sash '7 of the upper frame 1.

In order to permit of ventilation and at the same time prevent flies or other insects from entering the room, I have employed an ordinary screen 8 in connection with the window. It is manifest that as the lower sash 2 is forced upward and the upper sash 1 lowered, the outer screen 8 resting on the lower sill of the window, the inner sash 7 of the upper sliding frame 1 can be swung inward without affording ingress to flies.

The many advantages derived in the facility of cleaning the windows, &c., by making it possible to swing the glass-bearing frames 7 within the room are apparent, and when for any cause, such as reglazing in a more suitable locality, it is desired to remove the swinging sashes 7 from the sliding frames 1 and 2 the hinges C can be constructed with a slip-pin 19.

One of the principal objects of so constructing the window as to permit of the upper swinging sash to be opened only when it is lowered, aside from the appearance afforded having a groove formed in its top edge, staby such construction, is to obviate the dantionary bar 6 placed in said groove, and havger of disturbing or injuring curtains or other ing its ends project into the side strips 5, sub- 1 5 drapery suspended from the upper portion stantially as set forth. 5 of the stationary frame if the upper sashwere In testimony whereof I have signed this to swing inward from above the lower sash. specification in the presence of two subscrib- Having thus described the invention, what ing witnesses. is claimed as new is v y In a window, the guide-strips 4, 5, placed ILLIAM DEA) IO out of line with each other the sliding sash Vitnesses:
