Application mea April se, 1921. serial ne. 186,684.

This invention as indicated relates to a window construction. More particularly sald invention includes a frictional suspension for a window and means for controlling the same.

It also'includes an interlocking lrela-tion between the window sash and the window frame whereby the support at one side of the window coaets with the support on the opposite side of the window both with respect to movementin the'plane of the window and transversely thereof with means for adjustlng the degree of tension or pressure applied at elther side of the window. It also has in view selfadjusting `guide members which will automatically compensate for expansion-or contraction of wooden window frames and sashes and present binding action or'undue freedom of motion. It ,also contemplates dispensing with a parting strip and vertical stops in a window construction, and includes features of construction incidental thereto.

To the accomplishment of the foregoing and related ends, said invention, then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the'following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a front elevation showin a double y window and window frame embo ying the principle of my invention; Fig. 2 is a central vgrtical sectional view of the structure shown in Fig. 1; Fig. 3 is aphorizontal sectional view through the upper and lower winv dow sashes'when in overlapped or opened 40 posltion; Fig. 4 is a detail sectional view showing a resilient guide memberand adjusting means therefor; Fig. 5 is a front view of the res1lient guide member showing the ad fjusting slot therein; Fig. 6 is an enlarged detail'view of the adjusting screw;`Fig. 7 is a fragmentary front elevation showing a modified form of construction; Fig. 8 l1s an.en larged horizontal sectional view of a portion of the structure shown in Fig. 7; Fig. 9 is a perspective view of an intermediate stop between the upper and lower window sashes; vFig. 10 is a fragmentary perspective view showing a stop block secured to the upper wlndow sash; Fig. 11 is a fragmentary perdthe resilient guide member with reference to spective view showin a stopifblock secured to the upper edge of t e lower window sash; and Fig. 12 is an enlarged horizontal sectional view showing the relation of the guide members and a pulley for the window cord. r

As is clearly shown in Fig. 1 of the drawing, the window construction comprises a frame 1 which may be formed without vertical stops and with flat vertical faces against which resilient guide strips 2 preferably terminating in beaded edges 3 are adapted to be secured. The guide strips have flattened portions 4.- at their extreme edges which are secured by means of'screws 5 or the like to the window casing. The strips are formed with an intermediate curved portion 6 which causes 70 said beaded portions to be spaced outwardly from said casing. An adjustingscrew 7 1s secured through said intermediate portion of said guide members, said screw preferably havin a screw-threaded shank 8 and an enlarge head portion 9 between which is provided-a narrow neck rtion 10. The head is preferably polygons. in shape to permit ad- )ustment of the yscrew by means of a wrench.

The threaded shank of the adjusting screw is adapted to be received .in an internally screw-threaded socket 11 embedded in the vframe or casing. vOpposite the position of the sockets, which are mounted at spaced points along the frame, each resilient guide strip is provided with a slot 12. Each slot is formed with a narrow portion adapted to engage over the neck portion of the adjust` ing screw, and with an enlarged ortion permitting the ready engagement o the ad]u`st ing screw with its socket when the parts are assembled. A shield (not shown may be appliedover open (portion of the s ot if it is desired to make the construction substantially water tight.

When the parts are engaged in operative p'qsition, the rotation of the ,screws in one direction will bring the inner shoulders adja-y cent the narrow neck portions against the resilient strip and force it outwardly, and rotation in the opposite direction will bring the outer shoulders into action and will positively move the resilient strip inwardly. Thus pressure or tension may be provided for its action relative to its coacting guide member resently to be described.

e window sash, if of metal, is preferably provided with grooved lateral edges and if of wood, is preferably channeled to receive a grooved metal guide plate. The grooved member in cross-sectional outline is preferably of more than semi-circumferential extent so that it may be engaged about said beaded edge of the resilient guide strip, heretofore described.

While a degree of friction sufficient to support a window in open position may be secured by having the area of contact of the grooved members and guide strips of large extent, it is desirable that the degree of friction be controlled. -Where the device is applied to structures subjected to great vibration as ocean vessels, railroad ears, or motor vehicles, it would be desirable to use grooved members extending almost around the beaded members vand apply a high degree of tension to the resilient guide strips so as to suspend the window firmly between spring members.

For certain installations such as those requiring the ready removal of the window, or an equivalent structure, such as a screen, the grooved member may be formed with a shallow groove not engaging about the beaded ed eof the strip, but in such constructions adjustment of the friction must be provided for/solely through control of the pressure of lhe resilient strips inwardly toward the win- Where the construction is to be used in small boats, or in motor vehicles, or other instances, where a single window, or a single movable window sash is required only a single resilient guide strip need be provided at each side of the window, and the flat marginal portion of the guide strip may be se cured to the outer or inner portion of the frame as desired. Where upper and lower movable window sashes are required, as in most dwellings and other buildings, the invention provides for the omission ofthe vertical stops and the parting strip now commonly used. Thus, as is shown in Fig. 2 of the drawing, the upper sash 21 is supported upon guide strips 22 secured to the frame outside of the plane of the window, and the lower sash 23 is supported upon guide strips 24, secured to the' frame. on the inside of the v plane of the window. The upper frame memer 25 of the upper sash is provided with abeveled. face to Contact with a like face on a stop 26 at the top of the frame, and the lower frame member 27 of the lower sash is likewise bev- The other lower and upsashes are beveled, to coact with each other Vwhen the windows are in closed position.- It

will be noted that the resilient guide strips are slightly sprung apart as the beveled facesreferred to arebrought into contact and the windows held irmly in closed position.

completely In order to prevent air or moisture enter;v

ing between the resilient guide strips, where the usual parting strip between the upper and lower sashes is dispensed with, an intermediate stop 33 is provided (see Fig. 9) between the resilient strips at each side of the frame at the meeting line of the upper and lower sashes. The stop is preferably a member formed with a flange 34 for securing the same to the frame and provided with channels 35, 36, on its upper and lower sides, adjacent its respective lateral edges. The channels are widened adjacent the flange 34 and are open at the narrower ends. Stop blocks 37, 38, secured respectively to the lower portion of the upper sash and the upper portion of the lower sash (see Figs. 10 and 11) and extend into the space between the resilient guide strips, the narrow'neck portions 41, 42, of

said blocks not interfering with the free sliding action of the Window sashes on the guide strips. The stop block 37 is adapted to engage into the channel 36 of the intermediate stop and the stop block 38 with the channel 35. The contact faces 43, 44, of the stop blocks may be slightly beveled to coact with in any desired position. Where very heavy windows are to Ibe euipped with resilient guides, it may be found desirable-to provide counterweights and cables and pulleys. These may be concealed behind the resilient guide Strips which are made of larger size. In such constructions the use of parting strips between the upper and lower sashes would also be desirable to facilitate making the construction weather tight. In .the modified form of construction shownin Figs. 7 and 8, the lateral edge of the sash 51 carries a guide member 52 formed with a bead at its outer edge. A resilient strip 53 secured to the frame is folded upon itself to provide a groove 54 at its freel edge and has a rearwardly projecting flange 55 providing a housing for the counterweight.

The counterweight 56 is supported on a cable 57 extending over a pulley 58 supported at the top of the guide strip on a pivot pin 59 supported in ears 61 inte rally formed in said gulde strip. The cable 1s positioned by said pulley centrally over the groove in the guide strip.

The resilient guide strip 53 is provided with adjusting screws 62 to control the tension or pressure upon the beaded guide member. In addition there is provided means for adjusting thefriction of the groove upon the beaded guide. This comprises an adjusting screw 63 engaged inthe rearwardly extendin flange and passing through an aperture in t e body portion of the resilient strip and controlled by means of a thumb nut bearing against the body of said strip. Thus by means of said nut the clamping action of the grooved member may be controlled.

Other modes of my invention may be employed instead of the one explained, change being made as regards Lthe mechanism herein disclosed, provided the interengaging and interlocking to prevent lateral separation, and` means operable in either direction for adjusting .the 'amount of such frictional engagement.
