WINDOW.

SPECIFICATION forming part of Letters Patent'No. 783,164, dated February 21 1905.

Application filed July 22, 1904. Serial No. 217,633. I

To all whom it may concern.-

Be it known that I, ADAM WOELFEL. a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Windows; 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.

My invention relates to. a novel construction in a window, the object bein to provide a device of this character in which the sashes may be turned inwardly for the purpose of easily washing the panes on their inner and outer faces; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is aview in elevation, partly in longitudinal section, of a window constructed in accordance with my invention. Fig. 2 is a detail plan section, on an enlarged scale, on the line 2 2 of'Fig. 1, both the upper and lower sashes being shown at the lower limit of their movement and swung open. Fig. 3 is a fragmentary detail plan section, on an enlarged scale, on the line 3 3 of Fig. 1, the lower sash being removed.

I am aware that windows have been constructed which are operated on the same general principle as in my invention; but the construction thereof, so far as I have been informed, has been complicated or objectionable for other reasons.

In windows it is generally desirable that all fixtures should be invisible as far as possible,

' for the reason that the exposure of too much hardware is usually objectionable. It is also desirable that the operation of the same should be as simple and efiicient as possible, and to these ends my device consists in mounting in the guides A and B between the blind-stops C plates D, each provided between its ends with a pivot for a plate E, which is provided with an inclined slot F and is adapted to be turned up and be received in a recess G of said plates D out of the path of each of the sashes H and J. The said plates D are disposed between the limits of movement of said sashes and a distance about equal to the length of each sash. Said plates E are so hinged to the plates D that when the same are turned down they are limited in their movement, so that they cannot be turned farther than a horizontal position. In the lower end of each sash in vertical alinement with the inner end of the slot in each of said plates E, I provide a pin K, and in the upper end of each sash in vertical alinement with the inner end of each slot of the upper plates I provide a projection L, having an enlarged head M. A section end of each of the inner blind-stops on that side of the frame opposite to that on which the plates are mounted is made removable in any convenient manner.

My device is operated asfollows: When it is desired to clean the windows, the lower sash is first raised to a position about the upper end of the lowermost plate D, and the plate E pivoted thereto is then turned down, as is also the corresponding plate E, mounted in the outer guide. The lower sash is then lowered until the pin at the lower end of same enters the said slot in said lower plate E, and. the upper plate E is then turned down, and thus inserted over the top projection L. The removable section of the inner blind-stop is then removed and the said sash turned inwardly until the cord is exposed. The latter is provided with a ring O at its end, which is inserted over a hook P in said sash and is removed and inserted over a hook Q, provided therefor on the frame. Said sash may be freely turned on its pivot, so as to enable the outer face of the pane to be easily cleaned, and in turning same the said pin and. projection at the lower and upper ends of said sash will move to the outer ends of the slots. The slot in the upper plate E is of less width than the head M of said projection except at its inner end, so that after said projection enters the outer end portion of said slot it is practically locked in position. The slot in the lower plate E extends at a greater incline, and its inner end is deflected inwardly, so as to form a pocket R in which the pin on the lower end of the sash is received, so as to bring said pin in vertical alinement with said projection L and hold same against longitudinal movement in the said slot. To turn the outersash,

the operation is substantially the same, the lower plate E being turned down, the outer sash then lowered, and the upper plate being then turned down in the same manner. The removable section of the blind-stop is then taken out and said outer and upper sash turned inwardly until the sash-cord is exposed and disconnected therefrom. The said outer sash cannot be turned quite as far as the inner sash, for the reason that the latter remains partly in its pivot, and to enable the same to .be turned sufliciently inwardly to enable easy access to the outer face of the pane the plates E supporting the said outer sash are made of greater length than the plates E supporting said fixtures may be easily applied to old windows as well as new.

I claim as my invention A window comprising a frame and sashes vertically movable in guides in said frame, the blind-stops at one side of said frame being partly removable, two plates disposed in each of the guides at the other side of said frame between the limits of movement of said sashes and at a distance apart equal to the length of the latter, a leaf pivotally mounted on each of said plates and movable through an arc of ninety degrees, said plates being provided with recesses to receive said leaves and retain same out of the paths of the sashes when not in use, each of the leaves of the upper plates being provided with an inclined slot enlarged at its inner end, and each of the leaves of the lower plates being provided with a slot disposed at a different angle than the slots of the leaves of said upper plates and being deflected outwardly at their outer ends, thus forming recesses disposed in vertical alinement' with the inner ends of the slots of the upper leaves, a pin on the lower end of each sash adapted to enter the inner ends of the slots of the lower leaves, and a projection on the upper end of each sash, having an enlarged head adapted to enter the enlarged inner ends of the slots of the upper leaves, said pins and projections being adapted to move to the outer ends of said slots when the sashes are turned, substantially as described.

In testimony whereofl have signed my name in presence of two subscribing witnesses.

ADAM WVOELFEL.
