N ow, sincevtheconstructionmf the upper and lower sashes; slides",- andtheir oo-relat ing parts is similan; I- will: describe' in "detail tlIB-IIIGthOd-Of construction of the lower sash; slides,- and -1 othev: parts -connected thereto and cooperating;therewithix To [the slides 3 angle jstri'ps 5 are so securedthat one leg \of; each forms a :guide'for the plates :7 which extend the' full length of the sash' and are fastened one orr eaeh side'of Ithela'tteL; Thepla'tesfi -hh:ve' their front edges bent over outwardly .1 so that when thesash'iisin alignment with itsslid's these edges will each en'ga-gepthe front' margin of oneof the legsfi; The other legs 8 of the anglestripsextend outwards in'tlie stile grooves2 contiguous to -the rearsuw a faces of the slides-andsubstantiallythe full width of the latter. 1 v I Attached to-the frame 1' between the' stile grooves 2- are weatherstrips110 hav ing i11 wardly ,projecting portions 9 between the legs 8 and the -rear of the! slides --3. The latter are grooved longitudinallyfas shown at 3" to reoeive -the=-for?wardlyy;flexed murgins-9 oftheportionsg, Thus the-portions-9 of thealweatherstrips "form positioned between r the slides 3 and th-legs 8 of the angle strips and the forwardly flexed-margins 9 hold the opposed'slidesin spaced relation to one another.

' Inside: the frame- 1 erethe usu'aL sash weightsl2 having ordinary sashcords 13 fastened thereto; Thelutte'r-pess =-upwa-rds around the I usual" pulleys; '14, down between the stops2 and'yinto' the vertiea-l-slots l5 in the slides: -Towards-the -top gof the la'tta recesses 16 are provided to receive" the blocks' 17 which are heldin-position bygscrews 18 which pass through-thedegsJfi of, the-angle 100 pulleys 20. Around thesash cords 13 stops 23 are securedwhich contact the upper surfaces of the blocks." 17 when the sash has beenswung outwards to the, desired angle.

We prefer to use metal sash cords in which case the stops 23 are soldered to the cords. This .arrangementof-the blocks also providesmeans for holding the sash cords in line between the upper pulleys 14: and the blockst 7 On the lower endof each leg 6 a member 24 is fastened, these members '24 have outwardly projecting tlanges30 at their lower ends. Througheach leg 6 and member 24 is an opening 25 which forms a bearing for its pin 26. Intermediately'of their length tllB-PlIIS are provided with flats 27 which slide into slots 28-cut in the lower ends of the plates 7 The endsof the pins adjacent tothe flats are normally held in position by, means of spring catches 29 mounted on i the inner sides of'the plates.

The opposite ends of the pins have cams 31 thereon, which are adapted to force spring clips 32 againstthe front ofthe stops 2. These spring clips are secured at one end of the flanges 30. In this manner the rotation of the sash is em ployed to force the clips in engagement with thefrontstops to hold the sash and slides against vertical movement when the sash is in an inclined position. 1

- When the sash 4 has been swung inwards the spring catches 29 may be pulled towards one another and the ends'of the pins 26 released so that the sash may be removed from between the slides;

At the upper ends of the legs 6 lockingmembers 33 are revolvablymounted. These locking members have eccentric portions 34 which are so positioned with respect to the outwardly and rearwardly flared edges of the plates 7 that the said edges make contact with the eccentric portions and cause the locking members to turn as the sash swings back into alignment with the slides. The upper portions 35 of the locking members are offset outwardly so as to turn clear of theedges of the plates and have inward projections 36 at the front which turn down in front of the sash as the eccentric portions are revolved. In-this manner positive means are provided for preventing the sash from accidentally falling back into inclined posi- 22 indicates cavities .in the sidesof i shown, it is understood that the invention is susceptible to such modifications asfall with-- in the scope of the appended claims.

What we claim as our invention and desire to secure by Letters Patent is 1. In a window arrangement, the combina-- tion of a frame having stops therein, slides adapted to move vertically between said stops and having longitudinal grooves'in their rear sides, weather strips attached to said'frame and extending longitudmallybetween said stops, inwardly projecting poi-5 tions on said weather strips, a sashpivotally mounted between said slides, angle-shaped members on said slides, one leg ofeachfof said members being adjacent to said sash and the other leg of each of said members extending outwardly behind the inwardlyprojecting portions of said weather strips,

and forwardly extending portions integral with the inner ends of the inwardly projecting weather strip'portions takinginto the longitudinal grooves insaid slides. V

2. In a window, the combination of a frame having stops therein, slides vertically movable between said stops, a sash between. said slides having recesses-1n its outermar glns at-its lower end, plates onsaid outer margins having slots therethrough from TOW their lower ends, other plates on said slides having outward flanges attheir lowerends,

pins rotatably mounted intermediately of their length in said slides and said other plates, said pins havingfiats thereon to engage said slots so that-said pins and sash rotate together, spring means for holding said pins in said slots,spring members secured to said outward flanges having sub-- stantially vertical portions: substantially parallel with said stops and inbent outer ends, and camson'the outer ends of said pins adapted to force-the substantially vertical portions .of'said spring members into engagement with said stops.

3. In a window arrangement,-the combination of a frame having stops therein,

slides adaptedto move verticallybetween said stops, a sash pivotally mounted between said slides, pulleys rotatably mounted on said slides, other pulleys rotatably mounted in said frame at its upper end, sash weights in said frame, sash cords having one of their ends attached to said sash, passing aroundsaid first named pulleys, up and around said other pulleys, and having their opposite ends-attached to-said sash weights, blocks secured to said frame betweensa-id first named pulleys and said other pulleys having openings through them through which said sash cords pass, and stops around said cords between said blocks and said other pulleys, said cords and stops being adapted to move as said sash is swung pivotally so that the latter strike the upper side of said bloc-ks when said sash has been swung outwards to a predetermined an 1e thereby limiting the pivotal movement 0% said sash, and said sash weights being adapted to bal- 10 ance said sash during its pivotal movement.
