Application ieao'ctober 17, 1921. serial iro.A soz'sneA v To'uZZ whom itlma'y concern: y y

Be it known that I, BERNARD `HAUsMAN, a citizen of the United States, `anda resident of'the'borough of Man'hattan,. ofl the city of New York, intlie-Sta'te ofNew York, haveV invented certain new and' useful- Improvements inv VVind'oWs',l of whichthe following is a-speciication,reference beinghad to the accompanying'drawings, forming a part? hereof. f i i This invention relates'toi windows ofthe type known as double-hung, suchv as that shown in Letters Patent "ofi the United States No. 1,331,342', dated February 17, 1920, in which the sash; or each sash is arranged to slide vertically and is alsojarranged to swing inwardion'a horizontal axis for the purpose'of permitting ventilation without draft and also of permitting' ready access to both sides ofthe window, from within, for the' purpose' of cleaning. rPhe purpose of the'present invention is to' improve generally the construction shown and describedv inthe Letters Patent above mentioned', and more 'particularly "tot adaptv the sash supportingand-lockingdevice to metal construction, to provide for the concealment of the sash chains` by`which each sash is connected to the counter balancing vsash weights, to provide means whereby the sash weights, of theusual' square cross section, may be hung so as to travelin a plane parallel with the sashl and top'rovid'e means whereby the sashshall be locked by'its own swinging niovenient' against verticalfino'vement. Other features ofthe'invention will bel explained more fully hereinaftery 'with reference to the accompanying drawings in A which vthe invention is illustrated I asembodied'in suitable-'form in connection with .a window of usual fconstruction and in whichl f 1 Figure l isa view in front elevation, from within, of so much of the lower sashup per" sashandpjaIn'bv of the window frame as is' necessary to 'enable the application of the invention to be understood', the sash weight and chain being' shown -in `dotted"linfes 4while the lower'sash is represented inf its closed position. v I Figure 2 is a viewlofithe same in vertical section, as seen from the right lhand in Figure l.

The countel` balance or sash weight b is thus connected through* the chain b", the s tirrup b3, the stub b4, the plate b5- with its pivot,

and the link orarm c 'tothe sash. Y

' The armid; is also provided with Va stud ,di which projects toward the yadjacent box and on the box is securedV a locking plate e, whichfisgslotted,asat e, inwardly from.v

the .outer end of the plate, thatis, the` end .toward the outside of the Vwindow and is thickened at its inner end. The

plate' .ie is so placed that `the' slotv e.

is in alinement .withthe stud dofthe arm d when the lowersash is in its lowest or closed-fposition.k YTherefore as. soon as the]` inward 'swingingv movementof the sashis commenced, the-stud d5, moving with the arm d, as shownin Figure 3will enter the V slot Je and will thereby hold ,the arm (l from. upward land, downward movement The upper member of the plate 6,. above the slot c', is shorter than the lower memsasli is in a vertical position vand in readi ness to be moved upward; 'Itfwill be 'obv` served `that when the lower end of the arm al Vis thrust away fromithe sash by the above vdescribed cam action the rupper end of the arm willbe pressed toward the locking plate e and a. frictional stop to restrain free movementof the. partswillbe created." v

It is desirable to prevent thelsashyfrom being ,swung inwardly Yexcept whenJ it is inits lowe'stposition and forthat purpose ythere is fixed to thel boXa-stop a?, just 'above the level of they topv of the sash -@2,when

vai

ber, so that it does not interfere with the upward movement of thestudlcl6 when the the sash is in its lowest position, or, jwhat .is the same thingso far asthe action ofthe stop is concerned, just 'above the level of .somep/art whichfis Vfixed to the top "rail .ofthe sash and may be regardedas form*- ingV a part thereof. W'hen` the saslr-is-in vkits lowest position' the stop as does not prelvent the inward swinging ofthe sash, but as soon as `the sash isV raised from its lowA` Vest position the 4stop .as then Vprevents ,the yinward movement ofthe sash andformsa guide for the sash duringk its upward move-I ment. Y Y

To guide the sash in its continued upward movement there is mounted on the topy rail ...of the sash a spring pressed bolt orA latch ,f

which is adapted toenterthel vertical .rece'ss v a6 before mentioned and isfprovided" withV a knob.- f. Thelatch preventsrithe inward swingingfmovement vof the; sash when itis in its-lowest position and mustvjbewith@ drawn by hand topermit suchswinging movement and the knob f furnishes a means whereby the latch can be withdrawn and'at the same time the top of the sash can be pulled inward all in one operation.V

`At .the bottom of the Vsash is secured `a` pin orl ro'ller c which entersjthe vertical recess as and constitutes the pivot on which the sash is swung inward.

The advantages of the improved construction will be readily apparent without further explanation and it will also vbe understood that various changesin details of construction and arrangement can be made to suit different conditions of use without departing from the spirit of ythe invention which is not limited to the particular construction shown except as pointed out in the accompanying claims.

I claim as my invention:

l. In a window, the combination of a weight box having a vertical slot in its face plate, a sash, a sash weight traveling in the box, a sash chain located wholly within the box, a stud to which the chain is connected, said stud projecting through said slot, an arm pivotally connected at one end to the sash and at the other end to said stud, and a horizontally slotted stop on the face plate of the box, the arm having between its ends a projection adapted to engage said stop, whereby, when the sash is swung inwardly, the chain and the stud are held from swinging movement and the projection on the arm is brought into engagement with the stop.

2. In a window the combination of a weight box, a sash, a sash weight, a sash chain, a socketed vbracket secured to the sash, an arm pivotally connected at one end to the sash chain, a headed stud securedto the arm at its other end and forming a pivotal connection with the socketed bracket and a spring interposed between the head of the stud and the head of the socket, the

socket and the arm being formed with co-V f operating cam surfacesl whereby, when the sash is swung inwardly, the spring is placed under compression and the arm is pressed tightly against 'the socket to form a frictional stop. c Y

'3. In a window the combination of a weightbox, a sash, a sash weight, a sashchain, a socketed bracket secured-to the sash, an arm pivotally connected atone end to the sash chain, a headed stud secured to the arm at its other end and forming a pivotal connection with the socketedbracket,

a spring interposed between the head of the stud and the head of the socket, the arm BERNARD 'HAUSMAN
