The improved doublehung window forming the subject matter of thepresent invention comprises a frame orcasing 5 having weight compartments 6 and provided with upper and lower sashes 1 and 8, saidsashesbeingmounted for vertical sliding movementwithin the casing'and so construct-' edas topermit the sashes to be swung inwardly to open osition when desired. 7

Secured to-the frame or casingi andextendg ing7 thefentire height thereof, are outer hinge members 9, preferably formed. of sheetmetal and including angularly disposed portions llland 7| l.- the metal atthe ends of said portions being 'c'urled' or rolled to formtubular members or. sleevesflz and l3.7 One oflthese-hinge members is secured to each side of the casingby screws or similar fastening devices- I4, with .the. portion. Ilthereof extending. withinthe casingand disposed atfsubstantially right anglesto the portion ID, as best' shown in Figure 5 of thedrawings. I

Secured. to the verticalstiles of the lower sash 8 by screws I5, is acompanion hinge'member. I6 having a terminal. sleeve I] which fits within the sleeve 12, of the adjacent hinge member so as to permit sliding movement of the lower sash there onand also to permit said lower sash to be swun laterally to open position when desired.7- 'Securedjto the inner face cft'he frame of the upper.

sash 1 isa filler strip l8 and fitting over said filler strip andsecuredthereto and to the upper sashQby ajsuitable fastening device 19,.is an upper hinge member 20 provided with a terminal sleeveil 'whichfits within the sleeve 13 in the adjacent outerhinge member 97 and thus permits the upper sash to beadjusted vertically within the windowframe and alsoto swing laterally, to open position. Extending through the interen gaging sleeves and operatively connected with the 'upper and lower isashes, are windowc'ordsview "of the 1 22 which extend overisuitable pulleys 23 mounted in the frame and thence downwardly within the compartment- 6 for attachment to suitable weights 24. The sleeves [3 of the outer hinge members 9 are offset with respect to the sleeves I2 thereof so as to permit the upper sash to be swung inwardly to open position without interfering with the lower sash, the rear edge of the upper sash being cut away at 25 to permit swinging movementrof the upper sash without binding shownin Figures ,9 to 12 inclusive of the drawings. This assembly-comprises a vertically disposed substantially U-shaped member or strip 26 extending the entire height. of each sashiand provided with laterally extending flanges 2'l,jthe

portion 26, being adaptedto 'fit'within a seating 3 groove 28 formed inthe adjacent face of the win a terminal angularlip 30' which coac'ts with" a I cam 3| for the purpose of. releasing the U-shaped 1 .inember 26 from within. the groove 28 when it is desired to swingthe'jadjacentfsash'inwardly, as will be morefully explained hereinafter.fEach seated in eachjreces s is a fmetal casing 33 having outwardly bowed springs 3 attached thereto and 1 which serve to normally and .yieldably hold the 3 sash is providedwith a longitudinal recess32 and member 26 within the seatinsj roove so asto insure a weather-tight joint between the parts.

When; the member '26 is in extended position, 1 the flanges ,21Iwill bear .against, the adjacent portionof the casing33 and limit the inward movement of said member. Two 3| are preferably'provided for each window sash, each cam being secured'to a stub. shaft 34' journaled I in the adjacent window sash, and each stub shaft i being provided with'a terminal slot35 adapted to 1 receive a suitable tool for turning the cam. EX-

- tending laterally from each recess 32 and com- 3 municating therewith, is an auxiliary. recess: 36 3 which serves to receive the adjacent cam 3| and cause the U-shaped members or strips 26 to seat within the adjacent grooves 28 and thereby holdthe sashes against'swinging movement and,

I for swinging movement, it will be understood ,do'w frame." Extending, laterally from one side of each Ueshaped member 26 is an arm 29 having at the same time, insure a weather-tight contact 7 between the parts. While both sashes may be slid vertically at any time and each is, mounted that theinner sash must be swung inwardly to theposition indicated by dotted lines of Figures 3 and '5 beforethe oute'n's'ash 1 canbe swung inwardly to the position shown in Figure 5.

The construction of the'sleeve hinge members and their attachment to the sashes is such that either sash may be swung inwardly to open position' so that the window may be used'in the same manner as'an inwardly swinging casement window. If desired, a suitable packing 3% may be seated in the window frame and the'groove 28' formed in said packing in order to assist in providing a weather-tight connection.

3 In Figure'laofthe drawings, there isillustratedamodifie'dfmm of the invention designed to reinforce "and strengthen the side stiles of the sashes. .Inthis form ofthe device, onefof the vertical stiles of each sash is reinforced and strengthened by theprovision of a metallic casing 3'l1and'slidably mounted withinsaid casing is a hollow actuating member '38 which-receives the cam 39, said actuating member being provided with terminal hook'portions Mlada'pted to engage suitable-lips 4| carried by the U-shapdmember or strip42, there being bowed springs s31; disposed within the. casing 37' for causing the U-shaped stri 42 to yieldably engage the groove in'the casing when the cam 39 is moved to re 3 leased position. In this form of the device, when thecam-is rotated, the hooks .40, by engagement I with the lips 41, will retract the U-shaped'strip to'permit longitudinal movement of 'the arm 29 I whenthe cam .is rotated.

It will thus .be seen that, underordinaryv con T ditions, the upper and lower sashes. maybe ad- 'justed vertically of the window fr'ame'to any de 3 sired position and in which event the sleeve hinges act as guides, itbeing understood, of

course, that there will be sufficient clearance be- I tweenthe U-shapedmemberlfiand the groove 2a to permit vertical slidinginovement of the sashes while, at the same time, insuring a good 3 weather-tight contact with the window frame. 1 When it is desired to swing either the upper or lower sash inwardly to open position, a suitable tool is inserted. in 17116 slot-35- of the adjacent stub shaft 34 and the cam3l carried thereby rotated soas to retract the ,u-shaped member 1 against'the. tension of the bowed springs 34 and 5 thus release said U-shaped member from the v groove'28 so that either-sash is 'free'toswing 1 laterally to. open position withv the sleeve hinges 1 I as pivots.

verse direction, the Springs 34 will automatically By rotating the cams 3| in the re- 42 against the tension ofjthe springs 43 and,

3340 when the cam is moved to released position, the

springs '43'will cause the strip '42 to automatically-'seat within the roove in the casing, as will bereadily understood; While the sleeve hinge 'm'ounting'and weather strip assembly is particularly designed for use on windows of wood construction, it will, of course;

be understood 'thatthe'device maybe usedwith equallygood results on a metal window. It will also'be understood'that thedevice may be made in' different sizes and shapes and constructed of any suitable material without departing from .the spiritof the invention.

Having thus described th invention, what is.
