11 Claims.

One object of my present inventionis to provide a circle window of simple and inexpensive construction which has the desirable ieaturerof being openable without the necessity of providing a recess in the wall adjacent the window frame to receive the sash of the window.

Another object is to provide a circle window in which there are a pair of semi-circular sashes, one of which is fixed and the other of whichis rotatable so that it can assume either a closed position opposite thefixed sash or an open position when rotated to register with the fixed sash;

Another object is to provide a circle window in which the movable sash is guided in its movement by a combined guide means and weather strip arranged annularly of the window frame.

still another object is to provide the two sashes with meeting rails, one ofwhich' has a convex portion and the other of which hasa weather strip extending therealong and adapted to engage the convex portion and thus seal the joint between the meeting rails against air infiltration when the movable sash is in closed position, the convex portion serving to prevent distortion-of the weather strip as the movable sash, during the closing operation thereof, approaches closed position.

A further object is to provide a combined clamping and supporting bolt for the movable sash, which predetermines its path of rotary movement and which can be utilized to urge the meeting rails to bend toward each other, thus providing frictional engagement of sufficient magnitude between the movable sash and its guide means to lock the window in any desired position of adjustment.

A further object is to provide a circular window frame built up of lagging, the sections of which are so formed that the fixed sash is supported against movement, due to a distinctive shape of one section of the lagging and retained in position by a semi-circular blind stop which can be sprung into position in a groove especially provided therefor by another section of lagging of distinctive shape.

Still a further object is to provide an outer casing for the frame having joints which are eiiectively protected against the weather by rabbeted key blocks and which is of such internal diameter that it permits insertion of a screen having a circular frame to a position limited partially by the blind stop mentioned in the preceding objeot and partially by the section of lagging in which the blind stop is mounted.

With these and other objects invlew my invention consists in the construction, arrangement and combination of the'various parts of my device, whereby the objects contemplated are attained as hereinafter more fully setforth, pointed out inmy claims and illustrated in the ac'com- 5 panying drawings, in which:

Figure 1 is a vertical sectional view througha circle window embodying my invention and showing a screen mounted therein.

Figure'Z is a horizontal sectional view on line 2--2 of Figure 1, showing the frame mounted in the wall of a frame house.

Figure 3 is a sectional view similar to Figure 1 showing :the frame arranged for application to a brick or masonry wall. 15

Figure 4 is an outside elevational view of a circle-window, one oithe key blocks being removedand only a small section of the screen being shown in position. I

Figure 5 is a sectional view on line 5-5 of Figure 1 showing a semi-circular blind stop for the upper sash of my window; and

Figure 6 is a sectional view on line 15-6 of Figure 1 showing how the upper sash is mounted and supported in the frame of the window. 25

On the accompanying drawings I have used the reference numeral III to indicate an outer casing member. The member Hlis formed of several sections, the joints between which are indicated at H. These joints may be glued anddoweled to-: gether in the *usual manner, the dowels being indicated'atrll. I r

The iram'eiof the window is made of annular piecesor ringsof lagging indicatedat l3, [4, I5, l6iand II, respectively. The shape of the ring of lagging I3 is shown in Figure 5. It comprises a lower :half having an inner surface of a predetermined radius, such'suriace being indicated at i8: This surface is cut-away as at H! adjacent the lower part thereof to provide a sloping sill for waterdrainage, as willhereinafter appear. The upper half of the ring is formed at a relatively larger. radius indicated at 29. The purpose of this arrangement'is so that a'semi-circular blind stop 2| may be mountedandsupported therein. Support of the'blind stop is securedlby shoulders 22 which form the transitions from the radius l8 to the radius 20.; The blind stop, as indicated bydottedlines, may-first havelone I end inserted in position, whereupon the dotted 50 end may then be sprung on to its shoulder 22 and the blind stop will thereafter remain in this position;

The blind stop 2| normally retains an upper sashUS in position in the window frame but may be sprung out of the position shown by full lines when it is desired to remove the sash US from the window frame. The upper sash US includes a bottom rail 23, a semi-circular stile 24 and radial mullions 25.

As shown in Figure 6 the ring I4 is provided with a lower half of a radius indicated at |8a and an upper half having a radius indicated at 20a. This provides shoulders 22a, the same as in the case of the ring [3. It will be noted by referring to Figure 1 that the radius at 20 is slightly larger than the radius at 20-11, while the internal radius of the outer casing I0 is substantially the same as the radius 20a. Accordingly, when the rings of lagging forming the window frame are fastened together, the upper sash US can be inserted through the members In and I3 to its position in the ring l4. Its inner face will then rest against the ring [5 which, it will be noted, has a smaller inside radius than the radius 20a of the ring I4. Thereafter when the blind stop 2| is sprung into position, the sash US is effectively supported and normally retained in its desired position but can subsequently be removed if necessary for repair or replacement.

I provide a lower sash LS having an upper rail 23a, a semi-circular stile 24a and radial mullions 25a. The lower sash LS is provided with a peripheral groove 26 for guiding and weatherstripping purposes. Mounted in this groove is an inwardly directed flange 2'! of an annular weather strip W. The weather strip W may be made of bronze or any suitable resilient and rust-proof metal and is annular in formation. It has attaching

flanges

28 and 29 which may be fastened as by nails 30 to the lagging rings l5-and l6. During assembly the circular weather strip W is arranged in the groove 26 of the lower sash LS before the lower sash is placed in position in the frame. Before the circular inside stop 3| is mounted in the frame, the weather strip W together with the lower sash LS are inserted through the rings l6 of the flange 28 rests against the fixed upper sash US. The lower part of the fiange'29 is aligned with the joint between the lagging rings l4 and IS. The nails 30 are then driven into position, the lower sash LS being rotated during this operation to permit progressive access to the full circumference of the weather strip W.

A clamp bolt 32 is mounted through the rails' 23 and 23a and provided with a wing nut 33. This clamp bolt, as shown in Figure 2, is effective to urge the rails 23 and 23a towards each other at their center, thus slightly bowing them and producing suificient friction between the ends ofthe rail 23a'and the guide and weather strip W to prevent undesired rotation of the lower sash LS. When the wing nut 33 is released, the lower sash can be readily rotated a half turn to open position or returned to closed position, as desired. For convenience in the opening and closing operations, I provide a knob 34 substantially spaced from the center of rotation.

The rail 23a of the lower sash has a convex molding 35 extending throughout its length. Secured to the rail 23 of the upper sash is a weather strip W of resilient bronze or the like.

The weather strip W comprises an elongated leaf anchored as by means of nails 36 along one side edge thereof, the free side of the leaf resiliently engaging the convex molding 35 when the lower sash is in closed position. At the center of the weather strip W a perforation 37 is and I1 until the outer edge provided for the clamp bolt 32. The coaction of the weather strip W and the molding is such that an efiective seal against infiltration of air and water is provided whenever the window is in closed position.

The resilience of the weather strip W will permit the bending of the rails 23 and 23a, as shown in Figure 2, yet maintaining the weather seal contact between the weather strip W and the molding 35. Due to the convexity of the molding 35, the lower sash LS may be rotated from an open to a closed position without distorting the weather strip W. When the outer edge of the molding 35 engages the weather strip, it gradually and progressively springs the weather strip toward the rail 23 and finally permits full line contact between the elements W and 35 adjacent closed position of the lower sash.

In Figures 1 and 4 I illustrate the window frame as being mounted in a wall 38 of a frame house. I provide key blocks 39 which serve the double purpose of the usual ornamentation for circle window frame casings and protect the joints H of the circular casing [0 from the weather. I rabbet the backs of the key blocks, as indicated at 40, so that they fit over the outer edge of the casing l3 instead of being mortised into it as in the usual construction. Thus the key blocks provide a protective cover for the joints and can be neatly mounted on the casing 10.

Where my window frame is to be used in a brick or masonry wall, as indicated at 4! in Figure 3, the key blocks 39 are omitted and a circular molding 42 substituted. The lagging ring I4 is also provided with a portion out at a radius indicated at la in Figure 1. This portion and the portion M of the ring !3 provide a sloping sill for permitting drainage of water from within the window frame outwardly on to the casing l0 and finally down the outside of the house.

Within thecasing HI I mount a screen S, the frame of which is indicated at 43. The screen engages the stop 2| and also the ring l3 adjacent its radius l8, whereby the stop and ring serve as a screen stop. The screen may be held in position by any suitable means, such as hooks 4 and eyes 45 at the sides of the screen and window frame. The lagging ring I! serves as a plaster reception groove to interlock the whole frame in the wall. An inner circular molding 46 serves as an inner casing for the circle window. In addition to the clamp bolt 32 a look (not shown) can be provided, spaced from the center of rotation, if desired.

I have provided a circle window frame which has many advantages of construction and assembly from a manufacturing standpoint. At the same time the fixed sash is effectively supported and retained in position and the movable sash is arranged for ready adjustment. The joints between the sashes and between the movable sash and the frame are efiectively sealed against infiltration of air. These joints are such that the movable sash can be made substantially smaller than the frame, thereby providing sufiicient play to eliminate the possibility of the movable sash swelling and binding in the frame. The parts of the structure are so arranged that installation of the window frame and of the sashes in the frame is a comparatively simple and easy matter.

T, Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
