Application May 11, 1949, Serial No. 92,572 7 Claims. (Cl. 20-522) 1 This invention relates to improvements in window units and accessories, and more particularly to improved agencies and features in and of window units of sliding sash type, to enhance the ease of sash movement, to enhance the sealing qualities of the unit against air and thermal exchange, and very importantly to incorporate in a window unit improved provisions for manual removal of the sash from the sashway.
The subject developments constitute certain improvements over the subject matter of Letters Patent No. 2,426,474. issued to these-applicants August 26, 1947, and entitled Sash and Sash Guiding Means, attention being directed to-said patent fora more detailed description of certain difficulties prevailing in older conventional window units and certain practical solutions thereof, resulting from a continuing course of research and development leading tothe present improvements.
The present developments may be summarized as embodied in a window unit, usually of double hung sash type in which, in any open position of either sash it is susceptible of a virtually frictionless and eifortless lifting and lowering movement, and in which a degree of air-sealing effect is attained which exceedsthat of most if not all conventional window units equipped with weather stripping; a further and highly important phase of the present developments is realized in awindow unit in which the sash is susceptible of easy manual removal from, and reapplication to the sashway at any time, without tools or especial skill.
While the foregoing statement recountsmost of the major objects of the present improvements, there is further noted the objective attainment of improved accessory and hardware features possessing a high degree of individual and combination novelty, and all designed in furtherance of the purposes stated.
A further general object of theinvention is realized in a window unit providing the several advantages above noted, and yet which may be factory-produced so as to requirebut a minimum of assembly operations at the building situs, and whichmay be produced and sold, inspite of the added. features of useful novelty, within fully acceptable price. ranges.
Thev foregoing and many additional objects and advantages of the subject improvements will more clearlyappear from the. following detailed description of a preferred embodiment, particularly whenconsidered in connection with the accompanying drawing, in which:
Fig. l is a front or side elevational view ofa window unit as installed, and in which are incorporated typical embodiments of the presentimprovements, Fig. 1 being taken as viewed from the interior, or the room side of the window unit;
Fig. 2 is a vertical, partly sectional elevational view taken in a vertical plane, with certain of the parts considerably foreshortened, this View being particularly located by line 2-2 of Fig. 1;
Fig. 3 is an enlarged sectional view taken in a horizontal plane, from which intermediate portions of the-window sash have been broken away, Fig. 3 being taken along line 3--3 of Fig. 1;
Fig.4 is an isometric or perspective View of one form of' sash-carried fixture of the present assembly, including a guide roller for coaction with a track or rail element;
Fig. -5is a view similar to Fig. 4., of a roller fixture carried by the sash but differing somewhat in its structure and purposes from that of Fig. 4;
Fig. 6..isanenlarged, sectional elevation, furthershowing the construction of the fixture of Fig. 4 and its relation to the sash and sashway, Fig. 6 being located by line 8-6 of Fig. 3;
Fig. 7 is an enlarged'elevational View, partly in section, of a rectractible stop element for the upper sash, the location of this figure being indicated by line 1--1 of Fig. .2;
Fig. 8 is a sectional view taken in a horizontal plane particularly located by line 88 of Fig. 6, andshowing a retractible stop clement particularly adapted for coaction under certain conditions with the upper sash, and
Fig. 9 is an enlarged sectional view taken edgewise of. a portion of the rail or guide tracklocated at opposite sides of the sashway, Fig. 9 illustrating a camming-iormation on such track, which actsto urge the sash, when inor near closed position, into a weather-sealingrelation with an adjacent stop element of the sashway.
Referring now by. characters of reference to the drawing for a disclosure of theparts and their. functions, the upper sash is indicated generallyvat l0, and the lower sash generally designatedat H. Each such sash comprises sash stiles Hand l3, check rails is and i5, and the frame elements include the usual inside casing, stool, l7, apron l8, anda blind stop i9, and other suitable or usual framing. andsash elements, all familiar to those skilled in this art. There may, however, be mentioned for completeness, a vertical or pulleyjamb indicated at 25; into a groove or channel 26 of which is set the parting bead 28.
The sash assembly illustrated is of a design including rolling elements for guiding each of the upper and lower sash to assure smoothness and ease of operation, and is further of such nature as to facilitate manual removability of the sash, as heretofore mentioned. I'he physical provisions for these purposes include, at the opposite sides of each sashway, a metal track element 30 provided with suitable anchorage provision, later described, by which each such rail is securely assembled in place in vertical position within the sashway. The term sashway as employed herein, denotes the several channelforming and frame elements within and along which each sash ill or i i is guidedly movable and normally restrained to operation in its own plane; for example, as to the upper sash, the sashway is formed by the members 28, 25 and It, at each of the opposite vertical margins, together with the transverse or horizontal elements at the ends of the window frame.
Coacting with the rails 39, there are provided in the assembly shown, a plurality of roller fixtures, which are of two types, respectively generally indicated at 34 (Fig. 4) and MA (Fig. 5). These roller fixtures are preferably located in the regions of the opposite lower and opposite upper margins of each sash as shown, and will be hereinafter more fully described, it being presently noted that each such fixture includes a roller provided with a V groove 4%, and each of the rails 30 is provided with a bevelled or apexed rail-ball or roller-engaging head portion, as will appear from Fig. 3 and be later detailed. Certain of the roller fixtures include a leaf spring 3 5B (Fig. 4) by which a roller bracket is carried, such spring tending to bias the roller outwardly of the sash, as will hereafter appear.
By preference, each of the upper and lower sash is marginally routed or otherwise recessed to receive the roller fixtures, and in accordance with the present construction the fixtures 34 are utilized at the upper and lower left hand margins of each sash it and H, as indicated, while in the upper and lower right margins of each sash are disposed the roller fixtures MA as shown by Fig. 5. A general distinction is noted between the two types of fixtures in that the units 34 of Fig. 4 are of the stated spring roller is urged or biased outwardly by a leaf spring 3413, while the rollers of the fixtures 34A are not resiliently mounted. This selection should be understood as without limitation as to possibilities of employing spring-supported roller fixtures throughout, or in other arrangements on the sash.
Further describing the spring-carried-roller fixture 34, the body portion thereof is formed of a channel element 340 which may consist of steel or other metal of requisite rigidity, the base plate 34D of the fixture being suitably apertured as shown for the reception of mounting screws (not shown). body are in the form of parallel flanges, preferably of a considerably greater width or depth in the lower portion (Fig. 4) of the fixture, and between these widened portions is located the relatively heavy leaf spring 34B attached to the base of the fixture as by rivets 34E. In this form of fixture the free end of the spring or spring arm 34B is attached to an end portion of a U- shape channel member 34F the sides of which are apertured for the reception of a headed pivot pin 34G constituting an axis element for the type, in which the The sides of the channel roller proper 34H, this latter being preferably and as noted, of non-metallic character for silence of operation and long life. The roller is preferably grooved as shown with the sides of the groove 40 bevelled at an angle of 45 degrees, other camming profiles being possible to effect a camming action between the roller and the track or rail 3%. The outermost margins of the widened ends of the channel body 340 are inturned as shown at 34J, so as to form stops in this region limiting the possible outward movement of the guide member 34F carried by spring 343 and thus limiting the possible movement of the roller 34H in a direction away from the sash.
Many of the features of construction of the roller fixture 34A are or may be identical with some of those of the fixture 3 but with the omission of the spring arm MB. In fixture 34A, the sides of the deepened ends of the channel body 3lAi are brought inwardly and extended lengthwise, such extrusions 34A2 being apertured for the roller pin HA3 serving the roller 34Ad, which is or may be identical with roller 34H described above. The base plate of the fixture 34A is apertured for mounting screws in a manner similar to the plate 34D above described.
By preference a clearance is provided considerably exceeding the usual spacing or tolerances in a sliding sash assembly, between the pulley stiles and each adjacent vertical sash stile, this abnormal spacing being provided along at least one, and preferably each of the opposite sides of each sash, as is indicated at 4|, and a more than usual clearance is provided at the sides of the pulley stiles so as to permit a latitude of depthwise sash displacement in either direction.
For the purpose of permitting removability of the sash, each of the rails 36 on one side of the frame, in the present example the left hand side (Fig. 1) is provided in particular locations along the sashway, with recessed or cutaway portions 53, there being two such recesses for the rollers on the left hand side (Fig. 1) of each sash, assumingtwo roller fixtures at this side of each sash, the upper pair of recesses 43 serving the lower sash rollers. A corresponding pair of cutaway portions 43 in the lower part of the rail 39 serving the upper sash, accommodate, for removal, the rollers of the sash I0. These track recesses. together with the clearance provided laterally of each of the sash as indicated at Al, enable each of the sash when positioned with its pulleys opposite the companion cutaway portions, to be laterally shifted, i. e. in the plane of the sash and to the left (Figs. land 3), to permit sash rem-oval, as will later be described more fully.
For completeness of understanding of the full assembly in a preferred form, it may be men tioned, although forming per se no part of the present improvements, that each unit will be provided with one or more sash counterbalance units indicated generally at 50 (Fig. 1) these being suggested as of spring type currently available to the trade, and including a counterbalance tape or other tension element 5|, the tape or like tension elements being attached to the respective sash by fixtures providing an automatic captive provision for the counterbalance tapes, incident to sash removal. These features and the fixtures by which this result is accomplished, constitute the subject matter of a copending application for patent by these applicants bearing Serial No. 82,594, filed March 21, 19%9, and entitled Sepa rable Connections Between Sliding Sash and counterbalance Means, to which attention is nectors and fixtures in a form.
range of opening and closing movement.
directed for: a detailed description of such conpresently preferred As before briefly noted, the manual removabilityof either the upper orlower sash Ill-I lis provided for'when each such sash is moved to a more or less predetermined location in-its own sashway. lthas-been found most practical to provide a distinct removal zone for each 'such sashas it approaches its maximum open position. Thus the upper sash Ill will, for purposes of removal, be brought near a bottom position, and the lower sash l i will be moved to or near its uppermost position. Such a selection of sash removal zones-assures the normal guided actuation of the sash throughout all or most of'its usual The sash removal provision in the present structure is identified in part with-the track or rail recesses 43,- it being here noted by way of a general explanation that these recesses permit ashifting'movement of the sash when the rollers on that side of the sash adjacent the recessed track are brought opposite such recesses and the sash thus permitted to be manually moved for example to the left as shown (Fig. l) to brin the rollers 34H into the recesses 43. The-complete sash removal operation will be later referred to. The general purpose of the recesses 43 in the track 30 is introduced at this point for better understanding of'certain features of a metal jamb cover constituting a valuable feature of themesent improvements, as will now be described.
Overlying by preference each of the opposite pulley stiles 25, is a. specially'formed metal jamb cover which may be provided in strips'or rolls as an article of manufacture, and which .inpreferred formincludes a fiat base portion tit which in eifect provides a smooth planar overlay or liner between the pulley stile 25 and the sash. By preference the jamb cover is formed of 'a metal of non-corrodingcharacter, such a anodic aluminum, or aluminum alloy sheet. The-jamb cover is of such a width that its side margins extend slightly beyond the sashway proper and are either slotted into or gripped between the adjacent'elements, for example the member is (Fig. 3) and into a region between the member .25 'and'an element of the lower trim of the frame. Thus the side margins of the strip are concealed'and securely anchored in place. The primary anchorage of the jamb cover consists of a resilient, intermediate, inverted channel with sides 6 including formed internal beads 62, engaging and gripping conforming grooves usually but not necessarily of wood, this interfitting arrangement securely anchoringthe cover. In'sorne assemblies, it may be desirable to add a second set of bead formations 62, which erve to retain an optional, resilient, wearing and sealing channel 6 IA, formed for example of stainless steel, as is advantageous in aluminum sash assemblies, this auxiliary channel having internal, longitudinal beads 52A. 7
Secured asby riveting or otherwise through the outer part of the resilient channel portion just described, is a dust pad indicated at 63 and serving-when both sash are closed, as a seal between their adjacent marginal portions. This pad forms of itself no part of present improvements, but is mentioned for completeness. Similarly,
there may be convenientlysecured as to thechannel *6! of the right hand jamb cover of the unit, one. or .moreangle stops 64, this provision serving upon: introducing the roller sash-to the sashway,
in the parting bead 2B,
toprevent overtravel of the right hand margin of the sash H, beyond its own sashway, in a depthwise direction.
A further highly advantageousfeature of the present improvements consists in combining, preferably as a one piece structure, a metal track elementsuch as the: described member 36 .in each sashway, with the jambcover. It will appear particularly from Fig. 3 that the rail element or guide thus identified, is formed by a double folded portion of the body of sheet metal forming the jamb cover. The zone of fold, or bight, is, however, so conformed to constitute thereof a rail head or ball 65. This ball or head portion engaged by the rollers HE and BQAI-I, is of generally triangular sectional-shape the opposite ides of the head presenting a slope of the order of degrees to the plane of the flange or body of the rail 35). At this point it may be noted as a preference to form the rollers MH and MAI-I with both an inner groove and an outer groove, the outer St (Fig. 3) will normally prevent contact of the roller with the apex of the rail. This arrange-- ment has been found by experience to conduce to longer life, a considerable increase in area of contact between roller and rail, and to conduce to a better camming relation between the track and roller for a purpose later better appearing.
The jamb cover, preferably formed of a, single piece of metal as noted, is characterized by a further important feature consisting of one or more fixed cam formations 51, the locations of such camrning. portions being best shown by Fig. 2, and their detail best shown by Fig. 9. Each of these fixed cams consists of a laterally deflected portion of theball or head '65 of the track Si) in the regions shown, the deflection being an out-ofplane deformation of a short section of the rail in a direction tending to urge the lower sash outwardly toward the parting bead 28 and'in sealing relation with the jamb cover in this re gion, and tending to urge the upper-sash It inwardly or toward the parting bead with a similar weather sealing effect. Thus when such deflecting cam portions are engaged by the sash rollers, the sash is desirably tightened with the noted sealing effects.
From the foregoing it will now have appeared thatthe jamb cover in its most complete form includes in a :single structure the adjacent integral guide rail or track; the recesses such as 43 establishing the zones of sash removal; the resilient self-anchoring assembly feature of the jamb cover identified with its channel 6! and reentrant portions -62,-as well as the weather sealing efiects realized in the improved present design requiring no-more than a single spring arm -such as 343 (Fig. 4). Though the camming coaction of the bevelled rail ball-t5 and the bevelled groove of the spring mounted pulley 35H, it will appear that at such-times as eachsash is urged into sealing relation to the parting bead, or -more specifically the jamb cover, the bevelled coacting track and pulley will act to displace the pulley inwardly along the plane of the sash against the loading of the spring arm 343 by which the pulley is carried. Thus when the track cam formation 6? acts on the adjacent pulleys 35H, the sash will be urged in a tightening direction depthwise of itself or across its own plane, against the loading of the spring arms.
Conversely, whenever for any other reason the sash is deflected in a depthwise direction from its centered position in the sashway, the ball 65 of track rail 31} in coacticn with the groove of the engaging spring mounted rollers, will by reason of the stated carnming action cause the spring or springs 3413, to center the sash. Thus by virtue of the camming effect between the rollers and the track the single spring 343 or plurality thereof if more than one such fixture be employed, will provide in eiiect, a compound spring action in that t ese springs will tend to center the sash in the sashwa-y both in a lateral direction, and in a depthwise direction.
In view of the provision of a more or less definite and restricted removal zone for each sash, in which manual removal may be effected, it is deemed desirable to preclude any possibility of casual or accidental movement of the sash out of its normal path. With this urpose, provision is made as to the lower sash as will best appear from Fig. 5, showing a part of the sash H to indicate a sash portion a little below its uppermost or full-open position. In the position of parts as here shown, the sash-carried roller is slightly below the nearest track recess 13, so that the roller remains in normal operating engagement with the adjacent section of track 3!). The sash ii is precluded normally from being raised above such position by a hinged stop arm generally indicated at Hi. This conveniently consists of a channel member which is provided with a linear marginal abutment H and with a second abutment margin i2 at a right angle to that shown at l i. This channel element is apertured in its upper left hand corner (as same appears in Fig. 6), for the reception of a pivot pin 13 which extends through a web or flange portion of the track as. The channel formation of this stop arm is such that the counterbalance tape El and one of the counterbalance connector fixtures CCF may extend between the sides of this channel and is so related thereto that the stop arm Iii clears this tape and fixture in any position of swinging movement of the arm. Since the abutment of the sash l or a sash-carried fixture with the abutment margin ii, will preclude the adjacent roller from reaching the track recess Q3, it will be seen as impossible in this situation to remove the sash. When it is desired to remove or reinsert the sash in a manner which will be described, the stop arm 19 is moved about pin 13 through a ninety degree angle in a counterclockwise direotion, to bring it to the dotted position shown by Fig. 6. It will now appear that the sash is permitted a further extent of upward travel which is sufficient to bring the adjacent roller 34H opposite the deep portion of the adjacent track recess 43, thus permitting a shift of the sash to the left for removal purposes. In
this manner the stop arm provides a definite abutment in one of its positions, which at once establishes for the operator the exact position of the sash to permit its manual withdrawal.
A provision similar to the foregoing, but serving the upper sash Hi is shown in part in Fig. 2
translatory movement to and in somewhat greater detail by Fig. 7. In this case a channel or angle element T5 is secured as by a screw It in a position close to the lower end of the outer sashway serving the upper sash H]. The screw 16 or if desired, a separate screw, extends through a movable plate element 11 with sufiicient clearance that the member 11 which constitutes the stop proper may be moved into either of two sash-abutting positions, the vertical spacing of which will appear from the arrangement and proportions of a generally G-shape slot '58 in the member 51. The normal relation of parts with the sash it in place, is as shown in full lines by Fig. 7 wherein it will appear that it is impossible to lower the sash I0 below an abutting relation thereof with a bridge or ledge 89 of the member Tl. It may be noted that this latter may consist of a short length of channel or angle stock or may consist of a channel element providing a doubled plate portion IT. When it is desired to remove the sash H) from the sashway, the member if is first lifted slightly and moved to the right as same appears in Fig. 7, then lowered or dropped, and is given a short bring the member 11 into a position in which the shank of screw "it occupies the upper extremity of the slot 18 (see dotted position, Fig. '7), and in which the abutment 8E3 occupies a position sufficiently lower to enable the upper sash to be lowered to a point such that its left hand rollers 34H may enter the lower pair (Fig. 1) of the track recesses 43 and permit the preliminary shifting movement for sash removal.
It is felt that the function of the several portions of the window unit as an assembly, and of the several fixtures and items of hardware as described, will. have become fully apparent from the foregoing description of parts, but it may be noted for further completeness that, assuming it be desired to remove the upper sash, this may be readily done by lowering the stop ll, then bringing the sash iii to a lowered position such that the rollers t ll-I on its left hand margin are brought opposite the lower pair of recesses t3 (Fig. 1) thus enabling a movement of sash iii to the left (Fig. l) with the sash margin brought into the normally unoccupied clearance space 4| as is shown by dotted lines in Fig. 3. This translatory movement is suiiicient to cause the right hand side of the sash to clear its track and stops. The right hand edge of the sash may then be brought bodily toward the operator as with a swinging movement, then moved edgewise or in its own plane to the right (Fig. 1) a distance such that the sash will clear the left hand stops, etc. of the sashway. Reapplication of sash ID may of course be accomplished by a series of corresponding steps in reverse order from those described for sash removal.
Assuming the lower sash ll to be in normal operating relation to its sashway, and that it be desired to remove same, as for cleaning or otherwise, the stop arm it, positioned normally as in Fig. 6, will be raised to the dotted position, after which sash ii is raised as far as now permitted by the arm, the abutment E2 of which will stop the sash with its rollers opposite the pair of track recesses 43 which appear uppermost in Fig. l. The sash ii is then moved to the left (Fig. l) to bring it to the dotted position (Fig. 3), when the right hand stile of the sash will clear the adjacent frame elements and may be swung toward the operator, then shifted to the right (Fig.
.1), and clear of the sashway. Reapplication of this-sash is; now obviously,,made by reversing the sequence ofstepsrecited, it beingnoted that the provision of one or more stop lugs such as 64 (Fig; 3) will now preclude inadvertent movement of the sash beyond its own sashway.
It has been pointed out thatathe counterbalance tapes areorimay bevirtually automatically disconnected incident to the-aforesaid removal of sash, are similarly properly reconnected-to the sash vupon reinsertion thereof, being held captive when thesash .is out of the frame. As. noted, the-improvements making for this'result are-fully disclosed insand byapplication Serial No. 82,594.
