-3--3 of Fig. 4. p f Figs. 4 and 5 are plan sections on the wells -1 and'2, the sheaves 3 and 4 for the line 4- 4 of Fig. 1, showing the sashes in sash-cords, which, in the case of my invennormal and in swung-in positions, respece' tion, are necessary only at one side of the tively. j y 7 1 "casing. It also includes the inner stop strip Thecasing A includes' the sash-weight tions 19 in which the pivot-pin for the anti- "5, rigidl mounted on one side of the casing;

the simi ar hinged stop-strip 6 at the other side thereof; .and the stops 7 and 8. The present day construction of top and sill portions remains unchanged.

Mounted upon one side-wall of said casing A and extending vertically from the sill to a point just below the sheaves 3 for the sash-cords, are two parallel channel- strips 9 and 10, the former having one side-flan e abutting against the edge of the stop-strip 8, and the channel 10 being spaced from the channel 9, a distance equal to the width of the usual stop or guide 7 normally provided between the strip 5 and the-outer stop ,8. Openings are provided in the middle or webportion of each channel, 9 and 10, for thereception of screws or other fastening means 11. l v A The side-flanges of the channels 9 and10 are provided with opposed edge-flanges 12 to thereby choke the mouth-portions of said channels and provide guide-rails for the leaves 13 of the hinges for the upper sash B and the leaves 14 ofthe-hinges for the lower sash C, said leaves 13 and 14; being substantially similarly constructed. Each thereof is provided along one edge with the sleeves 15 for the hinge-pin 16 and, on one face with parallel L- shaped flanges 17 and 18, the free portions of which are spaced from the leaf a distance substantially equal to the thickness of the flanges 12 of the channels. Disposed on the inner opposed faces of said flanges 17 and 18 are projecfriction roller 20 is mounted, there being an opening 21 in the leaf to accommodate said roller 20. j

The said leaf is adapted for engagement with a channel by inserting the roller and free portions of the l.- shaped flanges 17 and 18 into one end of the channel for same either before or after the latter is mounted on the casin A. Thus the roller 20 rides upon the mi die or web-portion of the channel and the free portions of the L-shaped flanges ride upon the inner faces of the flanges 12. c

The channels are very shallow so as to require the side edge of the window-sash to be cut off to an extent less than the depth of the stops 7 and 8.

The leaves 15' for the hinges of the lower sash are associated with leaves 22 secured and set into the side-edge of the sash a depth Sufiicient to also receive the leaf 15, the pivot portions thereof being provided with flat faces to become flush with the inner face of the sash, in order to present a neat appearance.

The leaves 15 for the hinges of the upper sash di-fler from. the leaves 15 for the hinges of the lower sash, in that they are provided, each, with an edge flange 28 at the free end of which are the pivot sleeves for the pivot-pin. These hinges are of the three-leaf type and includethe L-shaped leaf 24 pivotally associated at one end with the leaf 15 and at the other end with the plane or flat leaf 25 which is secured to the sash, the latter being recessed a depth sufficient to receive the leaves 15, 2d and 25, and also to receive the outwardly projecting portions of the leaves 15 and 24, it being very desirable that no parts of the hinges project beyond the front and rear faces of the sash for purposes of neatness of appearance and in order that the stops 7 and 8 may be retained.

' In swinging the upper sash into the room, it first turns on the pivot between the leaves 24 and 25 through an arc of about forty-five degrees. Then the leaves 24 are swung through an arc of about ninety degrees relatively to the leaves 13 with which they are associated and the sash A may then be further swung until its total arcuate movement has aggregated about ninety degrees. The outward projection for the flanges 23 of the leaves 13 of the hinges'for the upper sash,

obviously throws the side edge of the upper sash, whenturned to its last-named position, outwardly from the plane of the leaves 13 a distance greater than the thickness of the sash, this being obviously advantageous in that it permitsthe upper sash to be turned to extend erpcndicularly to its normal position simi arly to the lower sash as shown in Fig. 5.

As shown in Fig. 1, only a little more than one-half of the stop 6 is hinged to the cue? 1 ing along its outer edge, it beingnecessary to raise the lower sash C, to clear the sill,

before it can be swung to the position shown in Fig. 5; The stop 7 includes a'removable portion which is iremovably mounted in the casing, the removable portion being ,that

which extends from'the sill to. about'the height of the hinged portion of the strip 6.

no I

It is fitted at its lower end into thepocket in the sill and is further held in place by the shoulders at the ends of the beveled meeting indicating the corner atthe inner edgeof the bottom'face of the bottom rail of the upper sash. lit will be noted that there is clearance between the shoulder 32 and the stop '7, such clearance' being also provided be tween said stop 7 and the similar shoulder (31) of the bottom rail of the upper sash, In order to remove the removable portion of the stop 7, the lower sash is first swung into the room and the upper sash lowered until its bottom rail is just above the window sill. The upper end of said removable pertion of the stop 7 may then, because of the aforesaidv clearance, be swung out of its oove until its upper .end clears the lower tending from the sill .to the same height as the channels.--The side edges of the sashes opposing said'strips are beveled ofl, as shownm Fig. 4, in order to permit said sashes to swmg on their pivotal axes. "Anti-friction roller carrying fixtures, which include the rollers,30,-are'mounted in recesses in said beveled edges of the sashes at about the same elevations as the hinges at the other I due to hinge-sag.

edges thereof, said rollers riding on the I strlps 29 and-coactingwith the hinge-rollers to cause the sashes to be easily raisedv and lowered to prevent binding of said sashes Preferably only one sash-weight is provided for each sash and the cords thereof attached, to the bin ed edge portions thereof and trained over t e sheaves 3 above the uper ends of the channels. Thus, the sheave ures for the other side. of the windowcasing may be omitted-and a saving effected. In order to swing the upper sash into the rodm, it must be lowered to the same posi tion as the lower sash, and the stop 26 removed. a 5 I It will be noted that the channels and hinges may be interchangeably asseeiated with either sideof the' window-casing, this being very advanta eous from the mantl facturing and insta ation standpointsa Inasmuch as, window -frames, and the sashes therefor are manufactured in standardsizes as to thickness of side rails of sashesand corresponding width of guide grooves therefor, the channels ca n be made, in widths to fit the latterand the hinges to fit'the sashes, the construction allowing for suflicient tolerance to obviate :close and accurate fitting during installation The latter is thusrendered so simple that persons' other than skilled mechanics-may effect. the

same withease, using only an ord nary plane and a chisel for the purpose.

" It will further be noted the removal of the stop 7 atone side of an ordinary window 1- frame and the small amount of labor re uired to cut the same to provide the remova le portion and then replace the upper 'portion per'manently and leave the lower portion removable, and that of removing, cutting and replacing the innerstop or turn, all labor-is confinedto the his removable stop that, aside upperand lower close fittin of thesashes in the frame and to overcome inding thereof when the sashes set of superposed hinges secured to the nonbevelled side of each sash and providing sides of said sashes being bevelled to permit are swung to open and closed positions, a

pivots for the sashes, one set of the hinges provided witha pair of oppositely disposed L-shaped flanges, and means fined to the frame and overlapping said flanges for slidably securing the hinges to the frame.
