Specification of Letters Patent.

Patented Dec. 8, 19114.

Application filed March 13, 1913. Serial No. 754,042.

To all whom. it may concern:

Be it known that I, FRANKLIN R. Esnnaon, citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Vindow- Sashes, of which the following is a specification.

This invention relates to new and useful improvements in window sash structure and as its principal object contemplates the provision of a window sash which may be readily and conveniently manipulated to place the outside of the pane in such position that it may be cleaned from the interior of the room.

WVith reference to the drawings, wherein, I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a front elevation of the several parts of the invention in assembled position. Fig. 2 is a vertical sec tional view of the window sash. Fig. 3 is a detail view with the parts of the structure broken away to more clearly illustrate the operation of the interior portion of the device. Fig. 1 is a detail perspective of the guide me. bers employed in connection with the removable sash. Fig. 5 is a detail view in side elevation of the roller mounting. Fig. 6 is a fragmentary sectional view showing the latch for the top sash.

Proceeding now to the description of the drawings, the numeral 1 designates a rectangular window casing of ordinary and usual structure having the guide strips 2 and 3 on each side.

Slidably mounted within the window casing 1 are the movable frame members of my invention designated as upper and lower frames by the numerals 1 and 5 respectively. Interiorly of the frames 41 and 5 are arranged a pair of sashes 6 and 7 which are normally arranged to move up and down with the movable frames 4: and 5. As a means for permitting the glass panes to be manipulated so that a person standin on the inner side of the window may have ready access to the outside of the pane for the purpose of cleaning it, I have mounts the sashes 6 and 7 between the frames 4: and 5 in such manner that either or both of the sashes may be partially released from the frames i and 5 and the upper ends of the inner frames 6 and 7 swung outwardly and disposed horizontally with the normal outer face 01' surface of the sash uppermost as illustrated in Fig. 2. To this end I have provided the frames 1 and 5 with the vertical guide members 8 which are preferably formed of a length of sheet metal, the longitudinal edges of which are turned or rolled and bent inwardly as at 9 to form a T- sliaped channel within which the rollers 10, rotatably mounted on the free ends of the laterally projecting pivot pins 11 carried by the frames 6 and 7, are disposed for sliding movement. The pins 1.1 are preferably secured to a reinforcing strip 12 attached to the frames 6 and 7 by screws 13 or other suitable fastening means. The innermost edge 9 of each guide member 8 is provided wlth a cut away portion as illustrated in Fig. 4 to permit the insertion of the rollers 10 within the channel portion of the members 8. The rollers lOare secured to the sashes 6 and 7 adjacent to their upper ends for a purpose to be hereinafter disclosed.

Tn its normal or assembled position, the frame 7 in vertical position and in order to prevent the outward movement of the lower portion of. the same with the resultant displacement of the member 7, I provide a latch 11 mounted on the lower horizontal member of the frame 7 and arranged to engage a keeper member 15 secured to the frame 5 as illustrated in Fig. 1.

For holding the top sa. h or frame 6 against swinging movement and supporting it in closed position at the upperpart of the member 1, I employ a pivoted latch 16, the lower end of which is adapted to engage a suitable slot formed in the lower horizontal member of the member 4:. The member 16 carries a laterally and outwardly extending latch tongue 17 which is preferably made in the form of an L, the one leg of the L being riveted or otherwise secured to the member 16 and disposed so that the lateral leg or latch tongue 17 is spaced from the lower horizontal frame member of the frame 4: thus permitting it to rest on the free end of the pivoted keeper member 18 mounted on the upper horizontal frame member of the frame 5. It will thus be seen that the latch member 16 in connection with the member 18 performs the double function of holding the glass sash 6 against outward movement and resultant displacement and at the same time holds the sashes 6 and 7 in closed locked position.

The actual construction of the invention being thus disclosed it now remains to describe the manner of manipulating the sashes when the windows are to be cleaned, briefly as follows: In swinging the lower sash 7 into the position indicated in Fig. 3 the latch let is disengaged from the member 15 and the frame is swung outwardly being pivoted during this movement by the roller pins 11. As the frame is swung outwardly the rollers move downwardly through the guide members 8 and the sash assumes the position shown in Fig. 3. The sash may then be swung upwardly again being pivoted 011 the members 11. The surface of the glass, which in assembled position of the sash, was formerly on the outer side of the window is then innermost and may be readily cleaned. A similar method is employed in manipulating the upper sash 6 and in this connection it will be observed that the frame 6 may be dropped to the bottomv of the window frame 1 and the member 7 raised to the upper portion of the member 1, thus enabling the operator to more conveniently clean the window.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is

Copies of this patent may be obtained for five cents each,

the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily Vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claim.

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

A device of the character described comprising a window casing, a sash frame slidably mounted therein, guides arranged vertically Within said frame member formed from strips of sheet material having their side portions bent inwardly to form overhanging flanges, guide member being provided with a cut out forming a passageway, a sash having one end portion pivotally mounted in said frame, and pivots connected with the free end portion of said sash and adapted to pass through the passageways of said guide into and out of engagement by the flanges of said guides.

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