SPECIFICATION forming part of Letters Patent No. 724,804, dated April 7, 1903. v

Application led .Tuly 19,1902. Serial No. 116,145. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, JOHN LAWRENCE CAR- TER, a citizen of the United States, residing in New York, borough of Brooklyn, and State of New York,have invented certain new and useful Improvements in Rotating Storm-Doors, of which the following is a specification.

This vinvention relates to an improved rotatin g storm-door of that class in which a num- Io ber of radial wings are rotated Within a stationary casing having segmental side walls, said wings being capable of rotary motion, so as to permit ingress and egress through the passage-way of the stationary easing, or being capable of folding, so as to be swung into position at opposite sides of the passage-way along the segmental side Walls; and for this purpose the invention consists of a rotating storm-door which comprises stationary segmental side walls, a disk shaped ceiling, means for rotatably suspending said ceiling, folding wings suspended from .said ceiling, and means for locking said wings together at their inner edges, said wings being rotatable 2 5 with said ceiling.

The invention consists, further, of segmental grooves in the under surface of the ceiling for guiding the folding wings, so as to permit of their being moved to a position alongside of the segmental side walls of the stationary casing, and guideways at the upper ends of two of the folding wings which are adapted to receive the other wings that are supported normally on angularly-arranged 3 5 guideways on the ceiling, so as to permit them to be folded alongside of the side walls; and the invention consists, lastly, of certain details of construction, which will be more fully described hereinafter and finally pointed out 4o in the claims.

In the accompanying drawings, Figure lis a front elevation of my improved rotating stormdoors,showing the folding Wings of the ysame in radial position for use. Fig. 2 is a front elevation of the door, showing the Wings folded alongside of the segmental side walls of the casing, so as to provide an open passage-Way. Fig. 3 is a vertical section online 3 3, Fig. 2. I Fig. 4 is a horizontal section on 5o line 4 4., Fig. l, the rotating ceiling being re- "proved storm-door.

moved and shown in dotted lines. Figs. 5 and 6 are similarsections showing the wings respectively in folding and folded positions. Figs. 7 and S are respectively detail elevations of a pivoted wing and a sliding wing in relation to the ceiling. Fig. 9 isa detail end View of one of the sliding wings carried on a pivoted wing; and Fig. 10 is a horizontal section of the Wings, showing their relative position when arranged radially to one another 6o and connected or locked for rotary motion.

Similar letters of reference indicate corresponding parts.

Referring to thedrawin gs, A represents the Xed supporting portion or casing of my im- This casing comprises a base a, a top plate or ceiling a', and segmental side Walls h b. The ceiling a is made disk shape and is suspended'centrally from a beam B, that is supported on short sleepers B', that 7o are supported on an open stationary ceiling B2, to which they are bolted, as shown in Fig.

1. To the ceiling a is attached a center bolt d, that turns in antifriction-bearings d' of the beams B, as shown in Fig. 3. ATo the under side of the ceiling are secured guideways C, that are arranged at right angles and are provided with flanged guide ways or rails c for guiding the antifriction-rollers c of the shiftable wings E E, which are suspended by 8o means of hangers from said flanged guide- Ways in such a manner as to be readily slidable thereon, either for being entirely removed from the same orfor being moved onto the guideways f, that are attached to the upper ends of two pivoted wings E2 E3, the outer upper corners of which are suspended by pivoted bolts e from the ceiling e' and guided by means of L shaped lugs e in grooved segmental ways e2 at the under side 9o of the ceiling, said ways e2 being provided along one edge of the same with metallic guide -railsc as shown clearly in Figs. 7 and S.

When the wings E E E2 E3 are arranged in 95 position for rotary motion within the stationary casing A, as shown in Figs. 4. and 10, the lower ends of the wings E and E2 E and E3 are connected or locked by means of hookand-eye devices H or in any equivalent ma'nroo ner, so as to hold the lower ends of the wings firmly together. In the radial position of the wings when they are locked together by the locking devices the wing E abuts against the inner end of the wing E', while the wing E2 abuts against the inner end of the wing E, and the inner end of the wing E3 abuts against the inner end'of the wing E, as shown clearly in Fig. l0. It will be seen from Fig. l0 that the connection of the wings is not absolutely radial nor that the wings are all of equal width, the wing E2 being slightlylonger than the wings E and E, which are of equal width, and E3, which is still shorter, and in this arrangement they are suspended from the ceiling and rotate therewith. The wings may be provided with hand-rails or other suitable devices for this purpose.

The inner corners or apex of the stationary guideways C at the under side of the ceiling are recessed, so as to permit the free sliding of the rollers of the shiftable wings from the stationary guideways to the guideways fot the pivoted wings E2 E3. A corner-piece t', in line with the flanges of the guideways, facilitates in guiding the shiftable wings from the guideways of the ceiling onto the guideways of the pivoted wings. Whenever it is desired to fold up the wings, so as to form a clear passage-way, as is the case during warm weather or when rotary doors are applied to Ihedoors of churches, dsc., where a large number of people leave the building at a certain time, the devices H are disconnected and the pivoted wing E2 placed into position shown in Fig. 5, sidewisein such position that the shiftable wing E is enabled to pass beyond the inner edge of the same onto the guideway at the upper end of the pivoted wing E3. Then the sliding or shiftable wing E is moved over alongside of and parallel with the pivoted wing E3, as shown in Fig. while the pivoted wing E2 is returned into line with the shiftable wing E, so that this wing can be moved over from its guideway on the ceiling to the guideway on thepivoted wing E2 alongside of and parallel with the same, so that both pivoted doors E2 E3, with the shiftable wings E E, can be moved along the segmental guide-grooves of the ceiling into position alongside of the segmental side walls 'b of the casing, as shown in Fig. 6 by dotted lines, the arrows showing the direction of motion of the pivoted wings when each pair of wings is swung into position adjacent to the segmental side walls. In this position the passage-way of the casing is entirely open, as shown in Fig. 2, so as to permit the free and unobstructed passage of persons and of large articles, such as furniture and the like, through the passage-way.

Whenever it is desired to replace the wings into radial position, so as to be used as a storm-door, the pivoted wing E3 is swung inwardly into position in line with one of the guideways C of the ceiling, so that the wing E can be shifted from the same. After this motion the pivoted wing E2 is swunginwardly until its guideway is in line with the other guideway C, so that the shifting of the wing E can take place next, whereupon the wings are locked in the radial position thus obtained, so that the wings of the door may be rotated with the ceiling.

The outer vertical edges of the wings, as well as the top and bottom edges of the same, maybe provided with fiexible edge strips for preventing the ingress of air, as is customary in doors of this class.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In arotary storm-door, the combination, with a stationary casing provided with segmental side walls and an open passage-way between them, of a rotatably-suspended ceiling, and folding wings carried by said ceiling, two of said wings being pivotally supported on said ceiling and the other two being slidably supported on the same, the latter wings being adapted to shift diametrically on the ceiling to and upon said pivotallysupported wings so as to swing with the same to a position adjacent the segmental side walls of the casing, substantially as set forth.

2.
