WINDOW v Dec.' 2,5, 1951 Filed July 19, 1945 4 Sheets-Sheet 5 INVENTOR. GEORGE E-GALL A TTOEWEYS n Patented Dec. 25, 1951 -UNITED. STATES PATENT OFFICE 9 Claims.

This invention relates to windows and more particularly to improvements in window frames and sash and in the coaction therebetween.

It is among the objects of my invention to provide a window in which the sash may when desired have great freedom of movement relative to each other and to the window frame but the window will also be weather tight precluding substantially all movement of air, moisture or otherwise through or around the window, its frame and/or between the sash, i. e., through or around the window as a whole. Another object of my invention is to provide a window which when one or more of the parts thereof are constructed of materials which tend to expand and/or contract through changes in the seasons, temperature, humidity and the like, will be capable of retaining its desired characteristics of being freely operable as well as being weatherproof. A further object is to provide a window in which the sash may be easily positioned, wholly or partly opened or closed, and may be positively secured in any desired position against movement, willful or otherwise. A further object is to provide a window the sash of which may be bodily removed from the frame whereby to facilitate the washing of the exterior faces of the sash from the interior side of the window. A further object of my invention'is to provide a window in which the sash may be easily removed and/or replaced without injury to the sash or frame and by the ordinary and normal manipulation of the working parts of the window. Another object is to provide a window the manufacture, installation and use of which will be I economical and which is adaptable to practice in a variety of materials or combination of materials as may be chosen either for purposes of economy or for artistic or architectural eifects.

A further object is to provide a window frame of l such rugged and durable design and construction as to substantially eliminate the need for employment of separate lintels thereabove.

A more specific object of my invention is to provide a window frame one side of which is movable transversely 4of its length whereby to grip and/or release the sides of the sash as may be desired to carry out some or all of the above objects. Another object is to provide a window frame having a movable part engageable with the sides of the sash and having a yieldable sealing member through which to permit movement of the parts and maintain a weather-tight closure throughout the desired range of movement thereof. Another object of my invention is to provide a window having an adjustably movable part of the frame coacting with the sash in such a manner that the sash may have around the peripheral edges thereof yielding rubber-like sealing members which may be compressed on movement of the frame member in one direction and in which the frame member has sufficient movement to effectively release the compressible sealing members.

Other objects and advantages will appear from the following description of a preferred form of my invention reference being had to the accompanying drawings in which Figure 1 is an elevation of my window in situ in a wall opening; Figure 2 is a horizontal section taken along the line 2-2 of Figure 1; Figure 3 is a vertical section taken along the line 3--3 of Figure 2; Figure 4 is a vertical section taken along the line 4-4 of Figure l; Figure 5 is a fragmentary transverse section taken in the plane of the line 5 5 of Figures 2 and 4 at and above the level of the window sill; and Figures 6 and I are fragmentary sections similar to Figures 2 and 4 respectively showing provisions for window screens.

To illustrate a preferred embodiment of my invention I have shown in Figure l the window W comprising an upper sash I, a lower sash 2 and a frame 3 set in a wall 4. It will be noted that the window has a conventional hasp 5 and has an operating lever 6 which may lie substantially flush with the wall surface, see also Figure 2. The handle 6 actuates the mechanism which permits the release of the sash for relative movement and conversely brings about the tight engagement of the sash to form a weatherproof and leakproof joint between the sash and the frame. For the purpose of example and not for any purpose of limitation I have chosen to illustrate my invention using more or less conventional wooden sash I and 2 mounted for movement in'and coaction with a metallic frame 3. Preferably the frame members are formed of extruded light metal shapes as will more fully appear. I have chosen these materials for the purpose of illustration and to show the adaptability of my invention to the use of various materials and various combinations of materials.

Turning now particularly to Figure 4 the frame 3 of my window may comprise a head I0 having an upward reenforcing flange II integral therewith as well asl downward reenforeing flanges I2 and I3 along with an inwardly positioned decorative and reenforcing ange IA,

the latter serving as a plaster ground or guide for the interior trim of the wall 4. As mentioned above the head IEB may preferably be formed of an extruded shape of such material as aluminum or may be rolled steel or other metal as economy and other considerations may dictate. Preferably the upward flange II is located inwardly of the exterior decorative wall surface, such as brick, and outwardly of the back-up tile, lath and plaster. The flanges I2 and I3 are preferably spaced to encompass the sash, sealing means and parts of the side frame members presently to be described. The bottom of the frame comprises the sill I5 preferably with a main sloping part I6 against which the bottom of the sash 2 bears, and a conventionally raised inward shelf portion I'I' lying'at-a higher level than the outward sloping portion It as shown. Preferably the shelf II has a lip I'Ia facing the sash and extending between the reveal flanges 25 and 42 of the sideframe members and has a downwardly extending return stripor flange lil corresponding to the decorative strip I/ above.

The head Iii and sill I5 respectively are joined and spaced by side frame members 2 and 4U of cross sectional form which I prefer to be substantially as shownin Figure 2. One of the side frame members 2li, leftwardly as viewed in Figures 1 and 2 is preferably of `a unita-ry extruded shape fixedly related to the head and sill. The side member 4o howeverhas movable parts and mechanisms presently` to be described by virtue of which the sash are gripped or released as may be desired. Both side 'framemembers 2) and 43 in addition to the functions about to be described, may also serve as structural columns resting on the sill and supporting the head of the frame. Preferably the side members are welded or otherwise xedly secured'to the head and sill on full bearing areas corresponding to their full crosssectional shape as shown in Figure 2 whereby to give rigidity and strength to the whole frame structure. The head and sill-preferably overlie the side members as at Illa and I5a, Figures l and 2.

The side frame member as shown in Figure 2 preferably takes a middle box-like'form v2i which with the central partition 22. Yconveniently forms separate wells for the sash weights 23 and 24 which may thus have free movement. Appropriate sash weight ropes o-r cables, see 82a, Figure 4, may pass over pulleys,- not shown, in the tops of the wells and connect the weight to the respective sash. A vertical flange 25 extending, as do the other parts of the member 25J, the full height of the frame lies inwardly at about the mid-portion of the central box structure 2l to set off the inner reveal of the window, and terminates-in a decorative trimming flange 2tv corresponding with the trimming flanges I4 and I8 of the head and sill respectively. The portion of the member 20 lying toward thefoutsideof 'sash' 2 thatthe "surface 32- serves for the sash I.

As shown in Figure 2 the flange Sil with the guiding rib 33 forms a longitudinally extending chan- 1 nel 35 for the sash I, and the rib 33 with the the window includes the stiffening flange 21 Y of the frame member.

l flange 34 forms a similar channel 3S for the sash Itwill beobSerVed that the rib 33 and flange 34 limit the depth of the channels Se and 36 whereby the sash'may be removed therefrom in a direction inwardly of the window whenever the sash are moved rightwardly no more than the height ofthe rib 33er the flange 34.

The side frame member 49, see also Figures 2 and 3, comprises a main channel portion 4I opening toward the sash and extending the full height The member 48 terminates on the inward side of the window in a flange 42 vcomplementary to the flange 2d above described and the flange 42, in turn terminates in a decorative trimming flange 43 corresponding to the trimming flanges I4, I8 and 2t. The member 4E) terminates on the outside side of the window in an outwardly extending angled flange 44 corresponding to the angled flange Y 28 and symmetrically disposed with relation thereto; the angled flange 44 terminating in a beaded terminus 45 having an exterior appearance corresponding to the bead 29, but the bead 45 contains a longitudinally extending groove 45 which receives and positively grips the outward longitudinal edge 41 of the sealing diaphragm 4B. I prefer that the channel 46 be extruded in the first instance with its opening wide enough to freely receive the edge 41 and, upon receipt thereof in the course of assembly of the parts, that the channel 45 be closed tightly upon the edge 4l' by forcible and permanent deformation of the material of the innerwall of the. groove 46.

As shown in Figure 2 the side frame member 4i] does not `of itself receive directly or have direct contact with the sash I andv 2, but rather the sash are received in and guided by a separate member 5i? ypreferably of box-like cross-section which is movable rightwardly and leftwardly, as viewed in Figure `2, in telescoping relation within the channel 4I, having a fairlyv close'and free sliding fit therewith. The member 5B -extends the full height-of the frame member 4t and has a squared top in a close but free sliding fit or contact with the under surface of the head I and has its bottom surface area inclined to the inclination of the sloping part I6 of the sill `I5 upon which it stands in smooth sldable engagement.

As shown in Figure 2 the member 50 is similar in its form to the box portion 2i of the xed frame member 2G, and has sash receiving and guiding channels 5I and 52 which preferably correspond in form and shape to the channels 35 and 35V respectively of the oppositely disposed frame member 2B. The inward flange 53 with its inclined face correspondings to the flange 34; and rib 54 corresponding to the rib 33;*-the flange 55 corresponding tothe Yflange 3D with aninclined Surfacev 56 corresponding to the surface Y32 and Y a y Ibeaded terminus f 5T corresponding to the bead 3| and symmetrically disposed oppositely thereof. The beaded terminus 51 has an inner groove 58 in which is securely gripped and received the whole length of the inner edge 41a of the diaphragm seal 48 and is secured therewithin in the same way that the outer edge 41 is secured within the channel 46, that is, in a mechanically secure and substantially air tight relation.

The diaphragm member 48 is preferably formed of thin flexible metallic or other fluid impervious flexible and resilient stock of light gage whereby to facilitate the rightward and leftward movementof the box member 50, as viewed in Figure 2. whilst sealing off the elements, air and weather from entrance to the main channel 4| of the member 40 and/or between the sliding surfaces of the box 50 and the channel 4|. I have found for example that sheet stainless steel of about 30 gage or less will serve the purposes of this diaphragm seal and is capable of substantially endless ilexing within the requirements of life time operation of my window. Such a diaphragm will yield readily within the space provided for it, and will not be adversely effected by exposure to the elements throughout a desirably long life.

It will be observed that the sealing member 48 preferably takes the form of a deep U-shaped channel within and behind the angled flanged 44 whereby to be substantially inconspicuous either from the interior or exterior of the window and presents substantially no different appearance to the eye when the window is in use than does the empty complementary channel lying behind the angled flange 28 of the member 20.

As viewed in Figure 4 it will be seen that the diaphragm member i8 is cut squarely at the top but is cut at the bottom whereby to conform to the inclination of the sill l5 at least when the diaphragm is in the position which it assumes when the box member 50 is advanced to its leftward-most position, as viewed in Figure 2, that is to say, when the edge 41a of the diaphragm has its most leftward movement, the bottom edges of the side legs of the U of the diaphragm may, be substantially square and level while the curving portion of the U of the diaphragm preferably conforms to a helix whereby to accommodate the slope of the sill l5. Since the leg of the diaphragm terminating in the edge 41a is to have movement with the box member 50, and the opposite leg of the diaphragm is to have no bodily movement rightwardly and leftwardly (but may have some movement incident to the flexing of the diaphragm) the lower edge of the curved part of the diaphragm will in its helical form tend to rise away from the sill in part when the box element 50 is moved rightwardly. To accommodate the tolerances which are desirable in production of these members, having in mind the geometrical relation above discussed, I prefer to provide a rubber-like sealing member 60, see Figures 2, 4 and 5, which may be of substantially U-shaped form as viewed in Figure 2, and is preferably of angled section as shown in Figure 5, having an upstanding leg 6| secured to the lower edge of the diaphragm '66 and having a somewhat horizontally disposed wiping lip 02 lying on and sliding over the sill l5 in wiping and sealing contact, being urged downwardly by the resiliency of the member 60. By the use of the rubber-lke seal 60 the lower edge of the diaphragm need not conform precisely to the desired geometrical requirements and may merely be spaced closely enough to the sill I5 to permit the wiping edge 6'2 of the rubber-like seal 60 to have continuous contact with the sill whereby to exclude all movement of air and weather from between the lower edge of the diaphragm and the sill l5. The rubber-like sealing member 60 may be secured to the lower edge of the diaphragm 48 either by cement, vulcanization or otherwise as may be found most practicable. A similar sealing member 10, see Fig. 4, may be attached to the upper edge of the diaphragm and have wiping and sealing contact with the lower adjacent surface of the head I0 whereby to seal the movable joint between the diaphragm and the head.

Referring to Figure 2 the member 50 preferably comprises two sash weight receiving wells 8| and 82 separated by a partition 80 carrying pulleys, not shown, over which weight cords such as the card 82a may pass and join the sash and weights. The rightward wall 83, as viewed in Figure 2, of the member 50 1ies parallel with the wall of the bottom of the channel 4| of the frame member 40, and carries a pair of brackets 84 and 85 in the lower zone thereof and a similar pair, of which one, 81, is shown in Fig. 3. The several brackets are suitably secured to the wall 83 as by rivets or other means. The pairs of brackets in turn carry, preferably rotatable, horizontally extending pins 86 and 88. The pins 86 and 88 along with their supporting brackets are preferably respectively spaced appropriately away from the top and bottom ends of the member 50, whereby to distribute the forces exerted upon the member 50 substantially evenly throughout the length thereof. Two pins so spaced are adequate for small and moderate sized windows. More pins similarly carried and properly spaced may be provided in larger windows to coact with appropriate actuating means or cams, presently to be described. Preferably the pins 86 and 88 are restrained from axial movement by proximity of the ends thereof to the walls of the channel 4 Juxtaposed to the pins 86 and 88 respectively are slidable channel members 90 and 9| each containing inclined cam surfaces defined by inclined slots 92 and 93 formed in the legs of the channels respectively, which slots receive the ends of the pins 86 and 88 respectively as shown in Figures 2 and 3. The channel members 90 and 9| each have in the base thereof a longitudinally extending slot, such as 04 in the channel member 90- and 95 in the channel member SI, through which pins or bolts 06 and 91 respectively extend and guide the channels 9| and 80 in their sliding movement upwardly and downwardly within the channel 4| of the member l0 as shown in Figure 2. The bolts 96 and 01 are xedly secured in the member 40 whereby to guide the channels 90 and 9| in their respective movements. A rack 98 is secured to the channelv member 90 and an oppositely extending rack 99 is secured to the channel member 9| through which the channels are given equal and opposite upward and downward movement under the influence of the pinion |00 which engages both racks. The pinion |00 is mounted upon a pinion shaft |0|; the assembly of the pinion shaft and racks being contained, journaled and supported within an appropriate housing |02, the latter being secured to the wall of the member 40 in the base of the channel 4| between the sliding channel members 90 and 9|. As shown in Figure 2, the pinion shaft |0| extends through the member 40 within an appropriate bearing and sleeve and out tnroughthe wall surfacing where it is engagjedfbyv tleelvever"6".'v APreferablylaiiiishingplateJ 3fis'""set int'Ot'tHe @trimming-edge 4'3i'bf the' member-'lid wherebyto proteotthe Walllsurface fromv fffi'erent andmanipulation" of /the'lever E1- Asviewed in Figure-31; elo'ckw'isefrotaticrrof*V the appreciated thaty theangled-slope of-gthe'ffslots 92 ands andthe corresponding "edgesfthere'of.-v which respectively bearupon"thefpinsl 86 and ataken withthe sizeof the pinion' I'i'iilwill. give any desired mechanical: advantage for moving. the box member rightwardly and leftwardlyA asviewed inigure 2, .and the: exertion of substantially any desirable force upon the edges of the sash.

In thisposition of the parts it will be observed-that: the channels engaging the lateral edgesof' the' sash affordampleguidance for the desired movement ofthe sash-while offering no substantial resistance-to such movement. movement of' the'member dtoward the memberV position-of either or beth `ofL them that"involun'v tary-"movement thereoffcan besecurlelyprevented.

On the-A other ,hand'forciblef' 9 sash were jimmied from its lower-most position still it would not then become freely movable because the resistance afforded by the grip upon the sash of the members 2| and 50 would persist even after a strained initial movement and even after the hasp 5 or any other such instrumentality were broken by a jimmy For like reasons children too small to reach or operate the operating handle 6 (which handle can, of course, be made removable against the contingency of undesired manipulation by larger children) will be unable to move the sash from the position that will alford desired ventilation for their sleeping quarters without offering the child either the hazard or temptation of falling through the' window opening.

When the member 50 is moved rightwardly from the position shown in Figure 2, it will be seen that the sash may be readily removed from either or both their respective guiding channels for the purpose of cleaning, replacement 0r repair. Fol` washing it is most convenient to lower the sash I down to substantially the level of the lower sash 2 and then swing the right ends of both sash, as viewed in Figure 2, inwardly, pivoting the sash loosely and separately in the channels 354 and 36 until the outside face of the upper sash is freely accessible for cleaning. Thereafter the upper sash may be allowed to rise under the influence of the weights 23 and 8| in and adjacent its guiding channels v35 and 52, whilst the outer surface of the lower sash is being cleaned. In like manner in the course of new construction the complete frames will be installed in the building walls and then left sashless until such time as the sash are desired to be installed by mere manipulation of the member 50 and the attachment of the sash to their respective sash weight cords.

The same facility of movement of the member 50 that permits the insertion and removal of the sash I and 2 also facilitates the insertion and removal of storm sash or screens for association with and removable attachment to the angled flanges 28 and 44 and closing contact with the head ange I2 and the sill portion I6 of my window frame, `see Figs. 6 and 7.. In Figure 6 the member 50 has been moved to substantially its extreme rightward position, and it may be assumed that the sash I and 2, suspended by their vsupporting cords, have been held inwardly of the window frame whereby to permit the insertion of the screen or storm sash |20 through the opening between the edge 3| of the flange 30 and thev edge 51 of the flange 55. The screen or storm sash |20 may have been given an inclined upward movement under the suspended window sash I and 2 whilst the latter are held inwardly; it being practicable to move and insert the screen |20 so that its upper edge preferably rst contacts the vunder surface of the head I8 of the frame inwardly of the fiange I2 thereof whereby to permit the bottom edge of the sash to clear the step II as it isA swung leftwardly as viewed in Figure 4, about its top edge as a center. After the screen |20 has been swung generally into the zone of the outside reveals behind the angled fianges 28 and 44 and outwardly of the flanges 30 and 55 it can then be freely moved rightwardly with its right frame member |2| lying more or less within and between the legs of the diaphragm 48. From this position the left frame member |22 of the screen |20 may be moved and swung to the right of the edge 29 of the flange 28 to permit the brackets f 10 |23, of which two or three may be vertically spaced along the edge |22, to be slid over and engage the outer face of the bead 29 whilst the shoulder |24 of the frame member |23 engages the inner face of the bead 29. On the rightward frame member or edge I2! of the sash |20 I provide movable U-shaped clips |25 which may be rotated about the axis i25a from the position shown in Figures 6 and '7 to a position where the outer leg |26 of the clip |25 freely exposes the shouldered face |21 of the frame member I2! to contact with the inward face of the bead of the angled flange 44. `With the clips |25 in their open position the screen |20 may be swung to the position shown in Figure 6 and then a quarter turn of the clips |25 will bring the legs |26 thereof into the position shown in Figure 6 to secure the screen in place. Meanwhile the bottom edge 30 of the sash |20 may rest upon the sill portion I6 as shown in Figure 7, and the top edge |3| may be spaced downwardly somewhat from the under surface of the head I0 but will have contact with the inward face of the ange I2, the rightward face as viewed in Figure '7, which lies in the plane of the outward face of the sash |20 as well as in the plane of the outward faces of the langled flanges 28 and 44, see Fig. 4. After the screen or storm sash |20 is in place the sash land 2 may be returned to operative relation tothe channels 35, 35, 5| and 52 Where they may again be guided and/or grasped by leftward movement of the member and used without interference from-the screen or storm sash |20 whilst the latter remains in the position shown in Figures 6 and 'l'. Removal of the screen or storm sash |20 will require merely the reversal of the operations mentioned for insertion, all of which is preferably done from the interior of the room or building in which my windowis disposed.

When the movable element 50 is in about the position shown in Figure 6, i. e., in a position of extreme rightward movement into the channel 4|, the pins 86 and 88 will have been moved to the outward ends of the inclined slots 93 and,92 as shown in dotted lines at 86a and 88a respectively. It will be observed that the slots terminate adjacent straight vertical edges 92a and 93a on the legs of the channels 90 and 9|. Further movement of the channels 90 and 9| toward each other as induced by the racks and pinion will move the channels relative to the pins 86 and 88 whereby to position the pins onthe surfaces 92a and 93a beyond the open ends of the slots 92 and 93 and thereby free the pins 86 and 88 from retained engagement with the channels 90 and 9|. In this free position the member 50` along with the pins 86 and 88 and their supporting brackets may be bodily withdrawn from the channel 4I, exing the diaphragm 48 in the course of such movement. When the member 50 is withdrawn from the channel il it may be swung leftwardly and upwardly as viewed in Figure 2, the diaphragm 48 serving as a strap hinge to facilitate such movement whereby to open the channel `lll for inspection and/or repair of the channel, rack and pinion mechanism or replacement of the parts thereof. Conversely in the initial assembly of the parts the order of operations may be reversed; the rack, pinion and channel mechanisms being first inserted and mounted in the channel 4I and then the channels 60 and 9| drawn together in their most proximate positions for receipt of the pinsf86 and 88 upon the surfaces 92a and 93a. Thereafter movement of the channels n 90 and Si to positions `similar to thatshownfin Figure 3l draws the member 5l! yinwardly ef the `.cl'iannel 4I more or -less `as may be desi-red.

In the initial assembly ef the whole freine,` tbe head, sills and head members are first secured As shown in Figure-2 the end of the pinion opits erating shaft l 1li preferably has a (square ornencircularshanl; uponvivhioh the hub ofthe lever 35 may be remeyeblyatteehed, ,As above mentioned removability of the lever 16 permits the sash `I and n2 to be gripped in anydesired position and left in such position substantially tamper-proof by removal `of lthe lever 5. The--remoyability of the lever -8 also -playsianother role. V'When the sash are firmly gripped between the members v5i! and 2l the lever Gmay be removed and reset on .s

the non-circular shank ofthe shaft .mi to `be proximate to 4the, removable stop pin 6a but spaced therefrom in the direction which Will permit substantially one -full turn of the lever n.6 -in the direction to release :the (sash before sentant-- ing the stoppina. I prefer that the inolin'aticn ,of the camslots S2 vand vjftalzen with the geared relation .of the pinion lLe!) to the racks 198 and 13,3 be such that a little less than one ful-1 turn of ,the lever 6 will move the ymember.lig! just enough to kpermit substantially free vmovement of the sash l and ,2 for any :desired upward or dovm- Ward adjustment thereof. The removable stop pinta therefore :reminds the Imabililll-ator to turn the lpinion lliil no more than necessary for this simple and ordinary regulation-of .the position of `the sash. When greater .movement of -themomber 5E! is vdesired the stop `pin @a .fis merelyre.- moved from -thegplate -lb3so that the lever 6 may be turnedas manyrevolutions as desired for any of the purposes above described. It may vbeemen.- tioned in passing Ythat movement of the member 5B away from the member 2l Awill so thoroughly free the sash of any vmaterial `friictional engagement inthe sash guiding channels of .these menu L a the degree of frictional drag existing `between l sash and Window Aframes.
