This invention relatesfto a new'and improved safety reversible. window and hasfor one of its principal objects the provision, of a window, the.

sashesoi which can be readily reversed whereby 5: both faces of the glass may be simply and efliciently cleaned or washed without the necessity of getting outside the window with consequent annoyance, exertion and danger.

Another important object of this invention is to provide a reversible window which shall be particularly safe on account of being proof against wind and weather'as', forexample, any tendency ofhighwi'nds toblow the sash inwardly or to blow rain water, cold winds or the like through the space between the sash and the frame.

Another important object of the invention resides in the provision of a safetyreversible window wherein the. usual sash cords and weights are v eliminatedwithout, however, impairingthe emciencyof thev sash, whereby the window may be openedlby sliding the same up and down relatively in the frame,..and which window, furthermore, includesfa provision for automatically positioning the sash in any desired position with respect to the framewhen moved up or down..

A still further important object of the invention is to provide means in a reversible window for automatically locking the sash in position with respect to the frame when the same is Irioved inwardly into full'or part of a reversed position for cleaning orventilating purposes/ j A stillfurther important object of the invention isthe provision in a safety reversible window of means for afiording adequate ventilation of any degree whenever desired,.and additional means for 'locldng the sash in room ventilating position while at the same time rendering the same proof against burglars, sneak thieves, or other intruders. ,A further object of the inventionfresides in the provisionof means for readily holding ourtains ordrapes'aw'ay from the window frame in such a position that they will not be in the way whenitis desired to-open the windows for cleaning, ventilation or other purposes, This means is automatically adjustable to various widths of window frames.

stiles l8 are provided with inner retaining strips 20 and outer retaining strips 22 for the purpose of retaining the sashes in position in the frame.

Slidably mounted in the frame is an upper sash having a top rail 24, siderails 26 and a meeting" rail 28. A lower sash is also provided having a meeting rail 30, side rails 32 and a bottorn'rail 34-.

Fixed into the side rails of each of the sashes as best shown at 36 inFigure 3-is a portionof a weather-strip element preferably made of sheet metal or the like which has one edge38 berit over and forced into a corresponding slot in thesash element 32. Adapted to "cooperate with this weather-strip element 36 a" corresponding weather-strip element, preferably made iii-one piecebut formed'in several portions comprising an outer portion 40, an inner portion 42, and sideelements 44 and 46 respectively, all of which elements are formed froman integral strip as best shown in Figures 2 and-3. Adjacent th'e bottom o'f; the s'ashelement 32, the member 36 is pivotally mounted in the corresponding weather stripf member 4046 by'means ofa pivot'pin; or the like 48. The weather-strip elements 40 -46 are" preferably of approximately the same height as- 'theheight of a sash as'best shown by the' dot't'ed lines in Figure 7, and are slidably' mounted incorresponding notches or grooves'formedin the stile It in conjunction with the'retaining strip-23.

as best shown in Figure 2. In this manner the' sashes may be moved up and'down in the frame,

the weather-strip elements moving along there r In order to prevent a sash, particularly. the

. lower one, from falling or being blown inwardly bymeansof air pressure or the like,a latchelement- 50 is provided which fits through corre-= sponding openings'in theweather-strips as shown in Figure 2 and which is normally impelled into latching position bymeans of a helical springi52 positioned there-behindin its mounting "in the sash member 32. A push-button 54 positionedin a suitable casing 56 is fixed in the sash for manual operation for retracting the latch '50 when; desired. g m a In .orderto lock the sash assembIyin any-der,

.siredposition relative tothe frame when the sash is moved inwardly about the pivot"; a locking plate 58 is provided mounted on the outer "end of the pivot rod 48 as best shown in Figured,-

and adapted to cooperate with a: shoulderv 60 formed onithe rod or shaft 48 is acorresp'onding.

shoulder 62 which is formed on a sleeve 64 which sleeve, inturn, forms part of acasing 66in which the shaft 48' operates. This casing 676 is built into the sash at its lower outer comer, and in addition to forming a housing for the 'pivotal mounting,

also provides quite, a reinforcing structure forthe corner of the sash. 1It,will be obviousthat when the sash is rotated forwardly about ,the pivot point 48, for example; as shown in-FiguresB, 7,

and 13, the cooperation of the shoulders 60 and V 62 will force the plates 58 outwardly, there being one on each side of the sash, into locking contact with the inner face of the stile l8, whereby the sash itself, with its weather-stripping and appur-' tenances, is thereupon locked in that position and cannot be moved either upwardly or downwardly until it is again restored to its normal.

vertical position with respect to the window frame whereupon a pin Simounted on the rod48 (Figure-5) will ride inwardly on a shoulder 10 formed on the casing 64 and release the plate 58 from "grippingcontact with the stile l8.

As best shownin Figure 6, a portion of the rod 48 inside the housing 64 is cut away to form a stop 90 and a corresponding extension is formed in, the inner face of thehousing or sleeve 64 as best shown at 92, which extension, when the sash is emoved into horizontal position, will contact with the stop 90, thereby preventing any further downward movement of the sash,

In order to maintain the sash in desiredpo sition with respect to the frame and llntel, a

friction gripping means is provided as best shown inQFigure 8. This comprises essentially a roller or the like 12 positioned in a housing '14 which housing isfltted into a corresponding opening in the stile it. In the housing is a leaf-spring II which acts against one cylindrical face of the roller 1 2 this leaf spring being positioned at an angl'e sothat whenthe roller is forced downwardly, a'corresponding tension of the spring re sults. Q Adapted'to act against the cylindrical face oflthe roller IZis the element of the weather.- strip, and it will be evident that upon raising the sash, the rolleris forced upwardly out of contact with this element 46' and'an upward movementfofthe sash is, thereupon, readily Upon a downward movement, however, theroller is forced downwardlyrand on account of the position" of the jleaf-spring I6, 11 811131 8v action results which retards such downward movement,

and the relation of the fspringto theother parts andlthefstifl'nessthereof is such that while the.

Asjb'estshown in '9, the top railf24 I the upper sash is weather-stripped with respect, tothe 'lintel it by means of a strip 18 of metal or other" suitable material formed in the correspondinggrooves inthe lintel l6 and rail, 24,ithe metal stripbeing preferably held in positionby nails or the'likelll."

In Figure 10 is shown a methodv of weatherproofiingthe meeting rails wherein a weatherstrip 82 isattached to the rail 30 and, avenue- 7 sponding strip grooved at itsbottom, as shown at 84, is attached to the sash rail 28. The line of juncture between the lower sash rail 34 and the sill I4 is protected; by means not a weather-strip 86,, shaped as best shown in Figure 11, attached to the sill Iitselfby means of nails or the like 88,

, As best shown in Figures 12 and 13, an appliance for permitting of an inward opening ofthe lower sash 32 a slight distance for thepurpose of ventilation, while at the same time locking the same in this position, is provided. This consists of 'astrip 94. hingedly mounted to a plate 96 fixed on the fa'ce of the sash rail 26, and which strip. hasfa groove," formed therein, widened at I to permitthe entry of the head I! ate. cone-.-

sp ndingly shaped latching element I02 fixed to theinner face of. the upper edge of the lower sash sashis held in position against the actionof grav- 4 f ity, it can be readily'moved downwardly by a suitable pushing force.

32. When the head of the element I02 is fitted into the groove 08 of the metal strip 94, it will be obvious that the lower sash will be permitted only a correspondingly limited movement about its pivot as best shown in Figure 13. This allows of free ventilation, while at the same time preventing unauthorized entry through the window.

A modified form of the combination ventilating and locking means shown in Figures 12 and 13 is presented in Figures 18 and 19 wherein the meeting strip 28 is provided with an upstanding latch element I04 fastened thereto and which has a head I06 for the purpose of loosely retaining a locking plate I08 thereon. This locking plate has a slot I I therein which slot teminates in an opening I I2, the opening being substantially circular, but having one side II4 restricted to an elliptical curvature. This opening is large enough to encompass the base of the element I04 and the base of a corresponding latching element I I6, which is likewise provided with a locking head A rotation of the plate IIO about the elements I04 and H6 into a position shown in the dotted lines in Figure 19 will, on account of the partially restricted circumferential portion II4 of the opening II2, bring these two elements into locking relationship with each other, thereby preventing opening of the window.

Additionally, a movement of the element H in the slot IIO when the plate I08 is in the position shown in the full lines in Figure 19 will result in an opening of the window sashes into a position similar to that shown in Figure 13, allowing venitlation but prohibiting unauthorized entry.

In order that the sashes may be moved into open position as shown in Figures 7 and 15 without interfering with draperies or the like I20, a supporting element is provided for retaining the draperies out of the way of the sashes.

This supporting element is best shown in Figure l4 and comprises a rod I22 telescopically fitted into a tube I24, both the rod and the tube having at their outer ends a bracket I26 which supports the curtain in an out of the way position as shown in Figure 15,

A clamping element I28 is positioned around the tube I24 as best shown in Figures 14 and 16, and an operating handle I30 is pivotally mounted in this clamping element, the same being provided with a heel I3I which, when the handle is turned to the right will lock the heel against the tube I24, thereby retaining the entire bracket in desired position in a window recess or frame. A link I32 is pivotally mounted to the handle I30 which link operates in a slot in the rod I22 and abuts in stopping relationship against the end of the slot as best shown in Figure 17. This supporting bracket can be readily removed when not in use and may obviously be adjusted to any width of window in a very short space of time. Furthermore, it will occupy only a very small space when not in use.

It will be evident that herein is provided a safety reversible window which combines many advantages, namely those of ready accessibility for washing of both faces of the glass, suitable weather-stripping against rain, winds and the like, provision of desirable means for ventilation and accompanying protection against burglaries as also other important features, such as automatic locking when closed, automatic positioning when open, and automatic self-support whereby sash cords and weights are eliminated.

We are aware that many changes may be made, and numerous details of construction varied throughout a wide range without departing from the spirit of this invention, and we, therefore, do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

We claim as our invention:

1. In a window frame, upper and lower sashes, grooves in the frame, stiles and weather-strips on the sashes, portions of said weather-strips slidably mounted in the grooves, and other portions of the weather-strips affixed to the sashes, together with a pivotal connection between the sash weather-strips and the frame weather-strips whereby the sash may be tilted inwardly, said pivotal connection including means for locking the sash in position with respect to the frame upon such inward tilting, said means comprising a shaft, a plate on one end of the shaft adapted to contact with the face of the stile, a housing in the sash through which the shaft passes, and cooperating cam means on the shaft and housing for forcing the plate into locking relationship with the stile upon downward movement of the sash, together with further means on the shaft and its housing for releasing the plate from locking position upon upward movement of the sash, said means comprising a pin mounted in the shaft, and a corresponding cam face'on the shaft housing.
