The present invention relates to windows;

and it involves certain improvements, here-.

described, whereby the sash be moved into theinterior of" the room in whichjthe. window .is located to or sashes may enable theouter face or faces thereof to be readily cleanedf According framecontaini'ng the sash or, sashes is mounted in a stationary. main frame secured in the window opening, and is designed to moverelatively to the latter frame in a dia vertical axis.

:rection to bring the sashes within the room, such movement preferably taking place about The side members of the sash or sashes are preferably connected by upper and lowerpairs of links-to the corresponding, side members of theauxiliary I frame to enable the sash toswing bodily between a position in which it is disposed wholly within the from the frame; the upper pair of links {outwardly and downwardly of its own weight into open position when released. The several pairs of links are connected at one end to forks carried by brackets secured, to the side members of the auxiliary frame; and these forks are preferably provided' with threaded stems which fit rotatably and adjustably in sockets formed in the brackets in order to permit a slight vertical change in the height of the pivot points to be obtained. l I I In the accompanying drawings forming a part of this specificationz] Figures 1 and 2' are diagrams showing a in accordance with my 111-.

sash mounted vention in closed and open positions, respectively;

Fig. 3 is a view similar to Fig. 2, but showing a slightly different arrangement of the supporting brackets;

Fig. 4 isa diagram showing two superposed sashes equipped with a device for operating them simultaneously; i

Figs. 5 and 6 are enlarged detail views of two forms of brackets; v V

Fig. 7 is a front elevation of a complete window, with both sashes closed;

Fig. 8 is a central vertical section of Fig. 7, but also showing in dottedlines the sashes and auxiliary frame in' open position.

Referring more particularly to the drawto the invention, an'auxiliary.

(or,-if preferred, there'may be the auxiliary-frame 25 is hinged along one .OfJtS vertical s de edges,

to the adjacent vertical s1de member of the fixed or mainframe 23."

The sashes 2&- .(assum1ng' that two areutilized, as represented in Figs 7 and 8) are" bodily into and out of designed to move frame 25; their outward movement preferably taking place automatically when the sashes are released, due to the weight of the sashes and to, the special mounting illustrated in detail in Figs. 1-6. Each sash, as therein shown, is supported by upper and V a single I sash only disposed in the frame). Inthe arrangement illustrated in Figs. 7 and 8, v

as indicated at 26,

lower differential arms'l and 7; the shorter upper arms 4c beingpivoted at their upper ends at 5 to the-side members of the sash and at their lower ends at 6 to brackets 15 secured to the corresponding members of the frame 25, while the longer-lower arms 7 are pivoted .at their upper ends sash sides and at their lower ends at 9 to similar bracketsfastened to the frame sides. The several brackets 15 may be at tached either to the inner faces of the frame sides (Figs. 1 and 2) or to their'rear faces (Figs. 3 and 4), and'they are formed with screw holes 16 (Figs. 5 and 6) for the insertion ofthe fastening screws therethrough'. These brackets, moreover, are equipped with forks 18 having threaded stems .17 which are adjustably engaged in threaded openings or sockets formed vertically in the brackets so that the forks maybe raised or lowered.

This vertical adjustment of the forks may be effected simply by rotating the fork itself (F g. 5) or byforming akey opening'21 (Flg. 6) through the bottom of the bracket at 8 to the to enable a key to be engaged with the forated, as indicated at 20, to permit suitable inga vertical rod 14 which is pivotally connected at 13 to the free ends of angular extensions 12 of the lower sash links 7. The

brackets 15 in this form of the invention are replaced by brackets 10 of slightly different shape which, however, may be, and preferably are,v provided with forked portions wherein the links '61 and 7 are pivoted, as before.

I claim a'smy invention:

1; A window, comprising a stationary mainframe, an auxiliary frame mounted in and movable relatively to the main frame, brackets secured to the side members of the auxiliary frame, vertically adjustable forks mounted in said brackets, a sash, and upper and lower link connections between said forks and the corresponding side members of the sash to enable the latter to move bodily out of and into the auxiliary fr me; said auxiliary frame being movable in a direction to bring the sash into position to enable its outer surfaceto be cleaned from within the interior of the room wherein the window; is located. i v

'2. A window, comprising a frame, brackets secured to the side members thereof, vertically adjustable forks mounted in said brackets, a sash, and upper and lower link connections between said forksand the corresponding side members of the sash to enable the latter to move bodily out of and into said frame.

3. A window, brackets secured to of, vertical forks having threaded stems which are rotatablyand adjustably mounted in threaded vertical sockets formed in the brackets, a sash, and upper and lower link 7 connections between said forks and the corresponding side members of the sash to enable the latter to move bodily out-of and into said frame.

In testimony whereof I afiix my signature -LUIS ESTRADA I comprising a frame, the side members there-
