Beit known that I, JAMES H. Gmsnv, a citi- -zen of the United States, residing :at-Pittsburg,

ion the coun/ty of Allegheny and State of Penn- Sylvania, lhave invented certain new and.use' ful Improvements in VVind'ows; 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 lnvention relates to certain new and useful improvements in windows for dwellings and other buildings, and particularlv to that class ot' windows which are pivoted vertically and adapted to rotate into an open or closed position. l Prior to my invention, so far as I am aware, pivoted windows have been so constructed and normally arranged with reference to the sill that the sash in itsrotary movement has always moved in a plane slightly above the planer of the window-sill, and consequently a neat or weather-tight joint could not be made.

' Efforts to overcome this inherent disadvantage have been suggested, consisting in providing the sill with a molding or strip adjacent to that half of the sash which in its rotary movement traveled away from the inside of the sill; but a concomitant .disadvantage of this larrangement laid in the fact that themolding or strip formed a check y against the rotation of the sash beyond one-half ofa completecir- "cle, and consequently great dii'iculty has been experienced in cleaning the outside. surface ofl the wind ow, and the further disadvantage has existed inthe fact that that half of the sill which f of necessityfwas devoid of the molding or strip was in a conditionI to admit between it and the window-sash wind, dirt, and rain, another disadvantage ofthe construction referred to lying in the fact that the entire weight of the sash is at all times exerted upon the lcentral,

lower vertical pivots and a consequent saglging of the same takes place each side of said `pivot to such an extent that the sill is marred and defaced bythe rotary movement of the sash. There has also been suggested in the type of windows made up of two wings respectively hinged to. opposite sides of the frame and opening and closinglike a` door an arrangement in which one of the swinging wings is capable of a slight Vertical movement on its ,hinges and is provided with a tensionspring which tends to hold it in elevated position. In order to hold the window closed in its lowered position, a lock is provided which vertically-movable sash.

Similar letters of reference indicate'like parts in the several figures of the` drawings.

A represents an ordinary window-frame with the sill B'provided with a rabbet or seat for the lower rail of thesash (Las is customary in the construction of Windows in which the sash is raised andi lowered to open and close thewindow, this vseater rabbet in the sill being essentially necessarytoform aguard against the entrance of wind, dirt, and rain when the window is closed. lhe'sash C is swung centrally upon vertical pivots DDt'. The upper one, D, is formedintegral with a rectangular plate E, and the latter is V secu-reid to the frame by screws ai. The lower piv t D' is formedintegral'with a plate'E, which plate is secured by screws Z) in a mortise on IOO Iio

the under sideof the lower -rail of the sash and formed with two longitudinal channels g g to permit of the movement, hereinafter described, of the eccentrics.` The sash is made lessthan the length of the opening in the frame, and consequently when the lower rail of the sash is properly seated upon the sillor in the rabbet thereof the upper rail ofthe sash will be below the under side of the npper part of 'the frame, and to close the space thus created I provide an ordinary follower I.the window.

F, lwhich rests upon the upper rail ofthe sash and is lifted thereby when the sash is raised and falls by gravity when the sash is lowered. This follower -is mortised out centrally to surround the upper pivot-plated) when the said follower is lifted, as is clearly shown at Fig. 2.

G is a lplate mortised in the upper rail of the sash and secured by screws Gand forms a guide andcircumferential support for the upper pivot D, and G is a similar plate secured b'y screws ci within a mortise in the sill B to rlnilarly guide and support the lower pivotv Above the lower pivot-plate E and within a mortise inthe lower rail of the sash is located a casting H, which is secured in place by the same screws b which secure the plate :,E'. This casting H is cored out centrally, as clearly shown, and when in position forms withthe plate E' a journal-box-for the shaft of the lifting device to be presently explained. The casting His also formed with two longitudinal channels e e to receive and guide the. eccentrics employedl to lift the sash.

The liftingdevice consists,'preferably, ofia single casting composed of an arm or leve`r I,

journal K. and preferably two eccentrics L,

so that said eccentrics will straddle or lie one each side'ofthe lower pivot D when in place. In locating the lifting device the journal K thereof is placed within the cored-out portion or box in the casting H, and the plate E is then putin place to confine the journal, the eccentrics L L being arranged within the channels e e," and the parts thus adjusted are secured within the mortise in the lower rail of the sash by the screws-. It will be seen that the lifting portions of the eccentrics L terminate in substantially straight feet at f,

so that after the cam-face portions of the eccentrics when rotated by the lever I have liftil the sash away from the sill to the extreme limit of movement the straight foot portions f will rest upon the guiding-plate G', and prevent the sash from dropping and the journal K from accidental rotation, and when in this position the lower edge of the sash is suliciently far above the sill of the frame to permit the former to be freely rotated to open When the sash is closed and the eccentrics are returned Ato their normal transition, the extensions or lnose portions g' g fs'wing under the solid portion of the plate G and thus form a substantial and, strong sashlock which prevents the lifting and rotation bf the sash unless the lifting device on the inside of the sash be lirst operated. If vthe locking device be thought unnecessary, the ec- Vcentrics L L may be made without'the extensions g g'; but I prefer to make them as described.

In lieu of the liftingdevice described Imay employ, any other suitable lifting devicesuch, for instance, as the modification shown at Fig. 8--consisting of .a rack and pinion. and though yI prefer the one fully described I do not wish 'to be limited in .that particular. The casting constituting the lifting device should of course be proportioned to the weight it is designedto lift, and, if thought desirable, the lever may be cast separate from the journal and eccentrics and adaptedl to it a square head formed on the journal.

In lieu of the followerF the upper rail of the sash may be provided with a spring-strip F', (shown at Figs. 10 and 11,) the springs tending to keep the upper edge of the strip always-in contact with the under side of the upper part of the frame A, or any other suitable means may be employed for closing the space between the sash and frame. It will also be understood" that in lieu of arranging the lifting devices within a recess or mortise in thelower railof the sash they may be reversed and placed within the sill, though I prefer to arrange them as described and illustrated.

Having described the construction and arrangement of the severalv parts of my improved window, I will now proceed to describe the operation of the same. The window being in a closed condition and it being desired to open the same, the lever I is turned to the right, as indicated by 'the arrow, until the journal K has rotated sufficiently far for the eccentrics to lift the sash free from the rabbet in the sill and for the feet or straight portions of the eccentrics to rest upon the plate G', during which movement the follower F has been lifted up into itspocket or box in the upper portion of the frame A. The sash may noW be freely rotated upon its vertical pivots D D at any angle to the natural plan-e of the window and to such an extent that the outside surface of the sash (or glass) is readily accessible from the inside for the purpose of cleaning the same.v When it is desired to -restore'the sash to its closed'position, it is rotated in a reverse direction until it reaches its normal plane within the frame. Thelever I is then thrown back and the weight of the sash causes it to descend within the rabbet in'the sill and to rest with its entire weight throughoutits entire width upon .the sill, and, as the sash lin ordinary use is for a greater portion of the time closed, it will be seen that its own weight perates to keep it in true and stiff condition, thus avoiding the sagging or distortion occurring inl pivoted windows as ordinarily con-r structed.

While I lhave herein illustrated and de- IOO scribed the means which-.I prefer for carry; lng .out my said invention, itis vf Jbvious-that'.-

other and equivalent means may be employed for that purpose, 'and I therefore do not limit thescope of my said invention vfurther than as dened in the claims hereto appended.

. What I- claim as new, and 'desire to'secnre by Letters Patent, is-.- v
