Claims. (Cl. 2ll-52) This invention relates to improvementsin window units, and more particularly to improved framing in and of winates Patent dow units of sliding sash type such as to enhance the ease bodied in a Window unit for example one of double hung Q or horizontal sliding sash type, in which either sash is susceptible of a virtually effortless lifting and lowering or sliding movement, and in which a degree of air-sealing effect is attained which exceeds that of most if not all conventional window units. A further and highly important objective is realized in a window framing which permits easy removal of the sash from, and reapplication to the sashway at any time.

A further object of the invention is realized in a metallic sashway liner over certain of the elements of the sashway structure, and which is designed in furtherance of the purposes stated.

It is an important objective to realize as an article of manufacture a cover or framing element formed of a single strip of metal, and formed to provide a relatively smooth covering over the adjacent jambs of double hung window units, and sill head jambs of horizontal sliding windows. Of further advantage, the cover is inexpensive to manufacture, simple and durable in construction, and adapted to be quickly and easily applied to the sashway of the window unit to afford the several advantages noted above.

An additional and highly valuable objective of the present improvements consists of a snap attachment feature, facilitating attachment of the cover element to a parting bead or the like. Similar provisions may be utilized in other sashway or framing elements such as a resilient weather-sealing element.

The foregoing and many additional objects and advantages of the present improvements will more clearly appear from the following detailed description of a preferred embodiment, particularly when considered in connection with the accompanying drawing, in which:

Fig. 1 is a vertical, partly sectional elevational view taken in a vertical plane in the sashway, with certain of the parts considerably foreshortened, this view showing the location and configuration of recesses and camming portions of the cover element;

Fig. 2 is a fragmentary sectional view taken in a horizontal'plane showing the left hand side of the sash assembled in its sashway, and disclosing the structure which constitutes the window framing; t

ass sts Patented May 13, 1958- Fig. 3 is a fragmentary, sectional elevation, showing the configuration of the recesses formed in the rails, and their relation to the roller fixtures carried by the sash, Fig. 3 being located by line 3-3 of Fig. 2;

Fig. 4 is an enlarged sectional view taken edgewise of a portion of the rail or guide track located at opposite sides of the sashway, Fig. 9 illustrating a camming formation on such track, and

Fig. 5 is a sectional view taken in a horizontal plane showing the configuration of the cover or framing element as disassembled.

Referring now by characters of reference to the drawing, the upper sash is indicated generally at 10 and the lower sash generally designated at 11. Each such sash comprises the usual sash stiles and check rails 14 and 15 (Fig. 1), and the frame elements include the usual inside casing, stool 17, apron 18, and a blind stop 19, and other suitable or usual framing and sash elements, all familiar to those skilled in this art. The window framing further includes a vertical or pulley jamb 21 having a groove or channel 22 into which a parting bead 23 is fixed.

Located at each sashway, is a metal track element 24 provided with a suitable anchorage provision later fully described, such rails 24 being securely assembled in place in vertical position within the sashway. The term sashway as employed herein denotes the several channel-forming and frame elements within and along which each sash 10 or 11 is guidedly movable and normally restrained to operation in its own plane. For ex ample, as to the upper sash 10, the sashway is formed by the parting head 23, pulley jamb 21 and blind stop 19 at each of the opposite vertical margins, together with the transverse or horizontal elements at the ends of the window frame.

A plurality of roller fixtures generally indicated at 25 coact with the rails 24. These roller fixtures are preferably located in the regions of the opposite lower and opposite upper margins of each sash. The roller fixtures 25 are structurally and functionally described in detail in our copending divisional application Serial No. 92,572

noted above, but for completeness of disclosure it willbe noted that each such fixture includes a roller 28 provided with a V groove 26 engaging a bevelled or apexed rail-ball or roller-engaging head portion provided on each of the rails 25. Certain of the roller fixtures 25 include a leaf spring 27 by which a roller bracket 30 is carried,

27 tending to bias the roller outwardly of I each. spring the sash.

By preference, each of the upper and lower sash is marginally routed or otherwise recessed to receive the roller fixtures 25. It will be notedthat, as described in the noted copending divisional application, certain of of spring type in which the roller 28 is urged or biased outwardly by a leaf spring 27, while of the fixtures are not the fixtures 25 are certain others of the rollers 28 resiliently mounted. It is possible to employ springsupported roller fixtures throughout, or in other arrange 4' ments with non-resilient roller fixtures on the sash.

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 31, and clearance is provided at the sides of the pulleystiles so as to permit depthwise sash displacement. I i i j Fig. 2 disciose's the structure of the window framing at the left hand side of thewindow unit, but it will be readily apparent that the right hand side is identical, being only reversed in position. I For the purpose ofpermitting removability of the sash, each of the rails 24 on one side of the frame, in the present example the. left hand side (Fig. 2) is provided. in.

particular locations along the sashway, with recessed or cutaway portions 32. There are two such recesses 32, one'i'fon eaclrof. the: rollers 28: on the left hand side (Fig. 2). of each sash; assuming two roller fixtures. 25" at this sidez. Tdreupper'pairofcrecesses.32'serve the lower sash rollers 28. A corresponding pair of cutaway portions 32 in: the; lower: part of the rail 24 serving the upper sash, accommodate,. for removal, the rollers. 28 of. 'sash i 10.

Asspreviously noted, the'manual removability of either the upper or lower sash. 10 -11 is provided for' when cach-suehrsashismoved to a more or less predetermined locationv in its own sashway. It is most practical to providea distinct removal zone for each such'sash as it.

Over-lying each=ofthe opposite pulley 'jamhs 21 is a specially: formedmetaljarnb' cover 33 which may be" providedin'strips or rolls as a'n. articleof manufacture,

and which'inpreferred form-includes abase prtion329g whichinefiect provides a-smooth planar overlayror: liner. betweentbe pulley jamb-21 andthesash; By preference, the jamb cover 33 is formed-of a metalotasnoncorrodingcharacter, such as anodic aluminum, or aluminum alloy sheet, and may be of rolled orextruded stock. The jambcover 33 is of such-a width that its side margins. extendslightly beyond the sashway proper and are either slotted-into or gripped between the adjacent elements, for example the member 19and into a region between pulley. jamb Z-Iand-an element of the lower trim of the frame. Thus, the side margins of the strip are concealed.

Thepr imary anchorage of the jarnb cover 33 consists ofaresilient, intermediate, inverted channel with sides 34, each side 34 including a formed internal bead or reentrant rib 35, each such rib engaging and gripping a conforming groove 36 in the parting bead 23. inter fitting arrangement securely anchors'the cover 33;

Secured as by riveting or otherwise through theoutr:

part of the resilient channel portion of cover element-33 just described, is a' dust pad indicated at 44 and-servings.

whenboth. sash are closed, as a seal between their adjacent marginal portions. This pad 44 forms of itself no part of present improvements, but is mentioned for completeness.

From Fig. 5, it is seen. that the base portion 29 of cover element 33 extends laterally outward of sides 34, and assumes an' angularv or slightly curved configuration in its disassembled form. The resilient sides 34 of the inverted channel are convergently related and the parts of base portion 29 on each side of resilient sides 34 are angularly related to give a curved appearance. When resilient'sides 34 are snapped on bead 23, the sides 34 are spread and hence resilient base portion 29, which is normally angularly related (Fig. 5), is held fiat against the jamb 21 as is shown in Fig. 2. Because of the normal angular disposition of resilient base portion 29, the cover element 33 is fastened to jamb 21 without the use of any screws ornails. The force exerted on jamb 21 by base portion 29, in itsfiattened, assembled state (Fig. 2)., is sufficient to retairu the base portion 29 securely against jar'nb' 21a in order for base portion 29 to exert this retaining force, it is obvious that sides 34 must secu'rely gripbeadi23.

A further. highly advantageous feature of the present improvements consists in combining, preferably as a one piece structure, a" metal track element, such as the described member 24 in each sashwa' withthe jamb cover 33'. It will appear: particularly from" Fig. 2 that the rail element or'guide thus identified is formed by a double folded portion of the body of sheet metal forming the jarnb cover 33. The zone of fold, or bight, is, however, so con'tormed-to constitute thereof a rail head or ball 45. This ball or' head'portion 45 is engaged by the rollers '28,- andis'shown as'ofgenerally triangular sectional'shape, the opposite sides of the head presenting a slope-of the order of'45degrees to the plane of the flange or body: of the rail24. .It is noted as a preferred structure, to'for'mthe rollers 28W'ith both an inner groove 46 and'an-outer'groove 47;. the outer groove 47 conforming substantially in'siope to that of the'sides of the ball 45 of the rail or track 24, and the inner groove preventing contactof the roller 28 withthe apex of the rail'Zd.

The jamb cover 33,Ip'referably formed of a single piece ofmetal asnoted, is characterized'by a further important feature consisting of one or more fixed cam formations' 50pthe locations of such camming portions 50 beiug-best'showmby Fig. l; and'their detail best shown by Fig. 4. Each of these'fi'Xed cams 50' consists of a laterally'defiected:portion of the ball or head of the track in the regions shown, the deflection being'an outot-plane deformation of a; shortfsection of the radio a*direction tending torur ge the lower sash outwardlyof.

From-the foregeingitrwill'now have appearedthatthe jamb cover 33 in its most complete form includes in a-single structurefthe adjacent integral guide-'rail'or track 24; the' recesses 32 establishingthe zonesof sash removal; the resilient self-anchoring assembly including'the snapon feature of the janib=cover 33 identified with itschannel and reentrantTportion's as well as the weather-sealing etteets in; cooperation-with the sash stiles, provided'by the cammingiformation'stk Itisithought that the function of-theseveral portions otithewindow unitas an assembly; and in particular the metal cover element 33 constituting; a portion'ofthe window framinghas becorn'etully apparent from the foregoi-ng'description of partsj lt may be noted'for furthercompletencss that; assuming 1' it is desired to remover the upper sash, the sash 10 isvmoved to alowered position so that the rollers 28 on its left hand margin are brought opposite the lower pair of recesses 32, thus enabling a movement of thesash to the left (Fig. 2) with the sash margin brought into the normally unoccupied clearance space 31 of the sashway. This translatory movement is suflicient to cause the right hand side of the sash to clear its track and stops. The right band edge of the sash 10 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. 2) a distance such that the sash will clear the left hand stops, etc. of the sashway. Reapplication of sash 10 may of course be accomplished by a series of corresponding steps in reverse order from those described for sash removal.

Assuming the lower sash 11 to be in a normal operating relation to its sashway, and that it is desired to remove same as for cleaning or otherwise, the sash 11 is raised to an uppermost position such that its rollers 28 are opposite the pair of track recesses 32 which appear uppermost in Fig. 1. The sash 11 is then moved to the left (Fig. 1) so that 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. 2), and-clear of the sashway. Reapplication of this sash is, now obviously, made he reversing the sequence of steps recited.

It has been pointed out that the counterbalance tapes (not shown) are or may be virtually automatically disconnected incident to the aforesaid removal of sash, and are similarly properly reconnected to the sash upon reinsertion, the counterbalance tapes being held captive when the sash is out of the frame. As noted, the improvements making for this result are fully disclosed in and by copending divisional application Serial No. 92,572.

Although the invention has been described by making a particularized reference to a single preferred embodiment,the detail of description is not to be understood as restrictive, numerous variants being possible within the principles disclosed and within the fair scope of the claims hereunto appended.
