Patented Aug. 25, 1953 UNITED. STATS ATENT OFFICE 4 Claims.
This invention relates to window construction for buildings and walls, where such are commonly employed, and more particularly to a frame and sash structure of the type that has removable features, draft prevention qualities, and makes the use of sash weights unnecessary.
In a particular form of frame and sash structure, frictional holding devices are mounted on the peripheral surfaces of the sash to guide and frictionally hold the sash in the channels of the window frame, as well as to provide features of removability. Such a form is indicated in the application, Serial No. 196,996, filed by the applicant on November 22, 1950- for Letters Patent of the United States. There are certain limitations to this form, which the present application is designed to overcome. In the first place, the holding devices consist of rollers of irregular contour traveling on rails in the window frame in such a manner as to provide a wedging effect that will bring the sash structure tightly against themselves and the ribs forming the channels, in which the sash slides. The specific structural details of the holding device used in this invention provide for rolling contact that .Will hold securely when the sash is positioned to suit the user, while at the same time permitting the sash to be readily operated by the user. Further the device is automatic in action and easily controlled by the operator. It is simple in construction, attractive in appearance and can be produced at relatively low cost.
One object of this invention is to provide a new and improved holding device and window construction that will avoid one or more of the disadvantages and limitations of the prior art.
Another object of the invention is to provide a window structure including an arrangement that will permit its manipulation to prevent undue air and rain leakage between the sashes and window frame; be removable and replaceable readily; and having a holding device incorporated in it to avoid the need for sash weights.
A further object of the invention is to provide a new and improved window sash construction that will tend to bind itself against leakage in the frame and otherwise anticipate any tendency to rattle or free itself from the holding device used with it.
Other objects of the invention will become apparent as the invention is more fully set forth.
To illustrate the general principles of the invention, operation and its conformity with the above objects, reference is made to the accompanying drawings. These drawings in conjunc tion with the following explanation present a. particular form by way of example that will enable the invention to be fully appreciated while the claims emphasize the scope of the invention.

Similar reference characters refer to the same parts throughout the drawings.
In the drawings, a conventional form of window frame Ill of rectangular contour is indicated. It is boxed in at the vertical sides 60 to fit into the building construction for which it is adapted. The inner walls I! of the vertical sides are constructed to receive the two sliding upper and lower sashes l2 and I3 used in it. The left hand inner faces of the walls I I are formed to provide a parting strip [4 in the middle, at the sides of which are angular channel surfaces [5 which rake towards the strip. Each of these channels [5 is surmounted by a thin fiat strip l3 of metal or other suitable material and fastened in place by screws l7. Longitudinal recesses l8 are provided at the sides of the channels I5, and serve to act as tracks for the peripheral longitudinal lips l9 atthe edge of the sash stiles 20. They are formed arcuately at 2| to cooperate with the arcuate portions 22 of the exterior surface of the channels I5 of the frame, when the sashesare allowed to settle themselves in the frame. This takes place under the action of;theiwedgind propensity of the sash surfaces against the strips E6.
The sash stiles have a sectional contmma$ dicated in Fig. 2. The lips i9 fit into the tracks l8 and the arcuate surfaces 2| and 22"coordinate with each other, with the inwardlyextending' angular surfaces 23 running on" the? strips I31 A molding strip 24 is attached'to' theupper horizontal rail 25 and is cutout at' 61 to-serve as a guide running on the strip I' l; This-keeps the sash aligned properly in the frame; It also extends outto seal up the space betweenthe front and rear sashes l2 and I3 when the window is closed, and the upper rail 25- is in alignment with the lower rail 26. When this happens-the lower bar 23 of the upper'window I 2 brings a ledge 21 on it against the molding strip 241mderneath.
The right hand stiles 20 of the lower sash" l3 and the right hand stiles of the upper'sash i2 have their inner surfaces 28- and 29 respec tively contoured to receive the window panes 33 and 32 respectively'andgive same an attractive appearance. They are held in place in any conventionalor suitable manner.
The left hand or opposite wall interior surfaces of the vertical sides of the window frame are fiat but inwardly angular with a rail [9' 1mbedded and fastened to them. On this'ira'iltrav els aroller 35 having a tapered exterior adapted to angularly conform" with the rail I 6; This roller 35 has an axle fixed in a bearing36 :moun ed on a cylindrical body 31 reciprocatable' in the well 38 ofa cylindrical shell 39 and pressed'forward or outwardly resiliently by a coiled-propel ling spring. 49. An open or. cup-like chamber-4| is provided in the body 3'? in a position oppo site to that of the roller, and a stem 42 integral with the body 37 extends through and beyond it. The stem 42 is arranged to align with the interior of a sleeve 43 extended inwardly into the-well 38 and is movable in it. The bottom 44 of the well supports thesleeve rigidly. The stem .42 is long enough to extend just beyond-the outer face 45 of the bottom 44 so that amovable lug 48 is pivoted with a small spring 49 forcing it outwardly. The spring 49 is imbedded in-the stem 42, and acts in a direction at right angles to the axis of the cylindrical parts. Apair of slots 59. disposed oppositely to one another in the wall of the shell serve. as guideways fora transversely projecting rod 5| to travel up and down it. The rod 5l'is installed transversely in. a passage 52 through the cylinder 31 andis arranged.- to keep. the latter positioned properly aligned with the roller, so the latter will travel on the rail H3.
The components 35, 33, 31, 38, 49 to 52' inclusive are parts of a holding unit 83. A flange plate 53 is mounted on the roller end of the unit and has holes 54 through which screws 55 pass to hold it to the sash stile and generally flush with the surface thereof. When the roller 35 is pushed back into the shell 39 it is out of the way. The side of the stile is drilled to receive a locking detent 56. This locking detent consists of a screwed-in sleeve 59 attached to the wall of the shell 39 with a plunger 5! operable exteriorly for engaging the head of the stem 42. This plunger is used for loosening the lug48 from contact with surface" 45 of the shell 39 when the roller is restrained in the shell and flush with the face of the stile. A coil spring 58 holds the plunger inside the sleeve 59 until the user pushes the plunaertagainst the spring.
In the operation of the invention, the removable"'sashes'--are inserted sideways in one side of the window: frame with the roller 35 retracted in the shell 39 and held in this position due to the engagement of the detent plunger 51 with the lug 48 and then directing the sashes in a tilting;manner-against theleft: hand side of the sash,- intothe left: hand side'of the frame, as showninFigure 5: Then the right hand side of the sash: is pushed'back into: place. This fiattens the sash'up' against the strip l4. Then the detent 56 is: operatedbypushing against the spring 58v so the plunger 51 releases the lug 48 and allows rol-ler 35 to;be forced outwardly by the-spring 49- to, frictienally engage the sash. The rollers permit sliding movement of the sashes during'opening. and closingthereof. The tapered rollers 35 of all the: holding units used travel on. the. angularerails -and tendt0 wedge the sashes against the strips-and provide'tightness. This isbyreason-of. the angular positions of therails and that of the tapered'faces of the rollers. This eliminates drafts andrattlingv At the same time, this. construction affords sufiicient friction to enable the sashes to beheld in any position theymaybe lifted to. This overcomes the need for sash weights to balance the sashes.
Any movement of the'sashes up and down in the frame tendsnto. press them towards the middie of. the frame. and against each other. The removal of. the sashes is'accomplished by a processopposite. to their insertion and placement inthe frame.
It will be noted that theformation of the stem 42 is thatof acylindrical shaft with its swinging head 48- overhung to=catch readily on the bottomsurface 45 of. thebody 39 and does so automatically. The plunger. S'L'makes contacts with a wearing pad 62 provided. ontheheadmember when the operator pushesonit. Thi releases the head off thesurface. The opposite end portion 65of the stem 42". isreduced in diameter to make it fit? more effectively in the hole 56 arrangedinj the partition fif4' f'or it. The normal position of the roller inthe holding unit is within the shell. out of the way. When released to project from the shell, the'roller' under the action of the propelling spring 49 presses outwardly and'makes contact'witli the rail in the windowframe. The stem 42passes through the sleeve 43; which serves asa positive guide and controlsthe inward movement of the body, as well-as a post for retaining the spring 49 from bending or getting out of alignment. The rod 5| passing'through the body 31 into the slot 5% prevents the body with its roller 35 from twisting out of linewiththe rail and latter runs on. Otherwise the roller would'riot beheld in proper alignmentand unnecessary or undesirable alignmentbetween these 'two wo'uldresult. The flat barBl extending out'fromtherail of the lower sash-J3. serves a's awhandlefor manipulating the r 5 sash both during raising and lowering, as well as removal and insertion in the window frame. A resilient stop clip 68 is used for locking the lower sash I3 in its raised position.
While but one form of the invention is indicated in this application and shown in the drawings, it is not desired to limit it to this particular form as it is appreciated that other structures and construction could be made that would employ the same principles and come within the scope of the appended claims.
Having thus described the invention, what is claimed is:
1. In combination with a window having opposite vertical walls, a parting strip located medially of the walls to form channel surfaces slanting inwardly towards the opposite ver tical faces of the strip, a pair of window sashes cooperating with the window frame, aligned conical rollers carried by an outer edge of said sashes, said rollers being slidable along the aforesaid channel surfaces and means for forcing said rollers against said channel surfaces whereby the sashes constantly tend towards each other to insure tightness therebetween.
2. The combination set forth in claim 1, wherein the rollers are received in housings provided in the sashes and means for locking the rollers within the housings and out of contact with the aforesaid channel surfaces, to allow removal of the sashes from the window frame.
3.
