Gaylord A. Brinson, Mooreland, Ind." v Application February 21, 1945, Serial No. 579,065

My present invention, in its broad aspect, has reference to improvements in circular and revolving window sash, thereby insuring any desired degree of ventilation, and eliminating sash weights'and cords, and the like, and providing a sash which is easily operated, will not stick or become loose, and which is weatherproof, sturdy and practical. More particularly, it is my purpose to provide a circular window made up of companion revolving semi-circular sashes, having a common axis of rotation to the end that the sash sections may be rotated with respect to each other to assume any desired position between fully open and fully closed positions; and there is provided means for locking the sash, and improved means for mounting the sash in unique and improved frames to the end that mounting and demounting the sash is a relatively simple matter. Furthermore, improved means are provided for preventing accumulation of water, and an improved and simplified sash and frame assembly.

Other and equally important objects and ad-- vantages of my invention will be apparent from the following description and drawings, but it is pointed out that changes in size, shape, form, materials, and construction and arrangement of parts is permissible and within the purview of my broad inventive concept and the scope of the appended claims.

In the drawings, wherein I have illustrated a preferred form of my invention Figure 1 is a front elevation;

Figure 2 is a section on the line 2--2 of Figure 1;

Figure 3 is a section on the line 3--3 of Figure 1;

Figure 4 is a front view of the frame;

Figure 5 is a section on the line 55 of Figure 4;

Figure 6 is a front view of one of the sash elements, and

Figure 7 is a section on the line 'I'I of Figure 6.

In the drawings wherein like characters of reference are used to designate like or similar parts- The numeral I designates a base, such as a wall or the like, in which is fitted my circular window frame 2. The frame 2 is formed with similar upper and

lower sections

3 and 4, respectively, joined together at their meeting ends by plates 5 attached by screws 6. The outside of the frames are annularly grooved as at 1. Each frame section is formed with an outer rim or annular frame or flange 8, and two stepped annular contours 3 Claims. (01. 20-52) 9 and In of which contour 10 has the larger diameter and supports the inner sash element ll, while contour 9 supports the outer sash element I2; These will hereinafter be called the sash supporting elements of the frame. At the lower part of the rim orflange 8 of the lower frame section 4 is an inclined opening l3, constituting a drain, and as shown in dot-and-dash lines in Figure 3, the base I has a sill l4.. 1 l

Each sash element (H and I2) is semi-circular, and the rim l5 of the outer sash is internally grooved, as at [6 to receive the flange I! of the stationary supporting frame I8, mounted in the contour H] to carry the inner sash element II. The inner sash rim H! of the inner sash is also grooved as at 28 to receive the flange of the frame 18. In assembling the sash in the frames, the outer sash is first mounted, then the stationary supporting frame I8, and then the inner sash ll, after which an inner circular framing rim 2| is screwed, as at 22, to the frame to maintain the sash and frame assembly. The framing rim M has an internal diameter substantially the same as the internal diameter defined by the flange ll. Each sash has a cross bar 23 and side extension 24. The cross bars over-lap and at a point midway the ends there is mounted a pivot bolt 26 which constitutes the axis of rotation of the sashes. The pivot bolt has a washer 21 and a knurled removable head 28 with a threaded shank 29 engaging in a threaded bore in the bolt body. The extension 24 tends to relieve the bolt 26 of the full load of the sashes since they engage the frame to extend the bearing surface against the frame over one-half of a circle and divert a greater part of such load to the frame 2. These extensions also function to hold the sash when assembling the device. Slots 30 are formed in the upper and lower sash to facilitate rotating the same, and spring latch pins 3| are provided to hold the sash in open and closed positions. Each latch has a keeper 32 and a head 33, and a spring 34 normally holds the pin 35 in engagement with an opening 36 in the opposing sash.

Each sash is grooved as at 31 and glazed with a suitable semi-circular pane 38 held in place by a molding 39 with a weatherproof putty or plaster filler 4B. Screws or other attaching means may be used to mount the moldings 39, depending on the material used.

From the foregoing it is believed that the operation and advantages of my invention will be apparent, but it is again emphasized that interpretation of the scope of my invention should only be conclusive when made in the light of the subjoined claims;

I claim:

1. A circular window construction, comprising a circular frame provided with internal circular walls of different diameter, said frame formed of semi-circular sections meeting end to end, a plate fixed to both sections at their point of jointure to hold the sections in assembled circular relationship, a sash confining flange. on the outer part of each section, a semi-circular sash fitting in one of said circular walls inwardly of said sash confining fiange, a circular stationary sash sup porting frame element mounted; theirarne inwardly of said sash adjacent said sash, a sash confining flange on the stationary sash support ing frame, the rim of said; sash being rabbeted.

at rotation, a framing rim secured to said frame.

outiizardly of said last mentioned sash to retains-aid sashw in said frame, the, internal diameter of said rim being equal; to. the internal diameter of said sash retainingfianges; a cross bar on each.

semi-circular sash, side extensions on each cross bar, said extensions adapted to relieve the weight of said sashes on said pivot means and provide holds for mounting said sashes, and a latching device for holding the sashes in open and closed positions.

2. The invention, as defined in claim 1, wherein said pivoting means includes a two-part pin engaging in an opening in the cross bars of the sash, and one part being externally threaded and having a head, and the other part being internally threaded and having a head.

3. The invention, as defined in claim 1, wherein the latching device includes a spring pressed retractible pin having a keeper and a head and mounted-on; one sash and engaging in an opening in the companion sash.
