To all whom 'it may concern:

Be it known that l, JACOB J. SCHALLER,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Revolving Doors, of which the following is a specification.

My invention relates to an improvement i in the class of revolving doorsjn/which of its embodiment Fig. 2 is a broken view in plan section showing the wings in their folded position; Fig. 3 is a vertical section taken through one of the hinges connecting a wing with the center-post,l on line 3-3, Fig. 4; Fig. 4 is a section on line L1-4, Fig. 3, and Fig. 5 is a view showing the two hinge-members in unassembled rela-tion with the connecting links and spring and stopdevices on the members. g

The casing 6 shown comprises the usual members of arc-shape in cross-section forming the passageway, with an axially rotatable central post 7, from each corner of which radiates a wing, four wings being represented in Fig. 1, numbered, respectively, 8, 9, 10 and 11, hinged to the post and separably connected` as by chains 12 for causing the door to be operated in the ordinary manner, under normal conditions, by passing through the passageway.

y rlhe`primary object of my invention is to. provide a hinged construction of the post and wings whereby each wing may be turned on its jhinge through 270 degrees of a circle,

c or approximately that extent, to fold the wings into the parallel relation represented in Fig. 2, when desired, as in case of panic or to have the door in collapsed condition for any other purpose. That object is accomplished by the following described construction.I

The post 7 is of square cross-section with rounded corners. Each wing is a solid'structure, being rigid or non-sectional throughout; and it is hinged at its mner edge tothe post, that edge being rounded like the adjacent post-corner, and has exible weather-stripping 13 let into it. The hingeconnections are provided at proper intervals along the rotary post, thus near its 'upper and lowerends, and also at one or more in' termediate points, as may be required. Each hinge comprises two link-connected mem- The members 14, of metal, are let into'the post corners and maybe fastened 1n place by screws, represented at 15 in Fig. 5. This member is centrally bored longitudinally to accommodate a pintle 16 and is formed at intervals on its face, which is rounded to conform to the post-corner, with sockets 17, of which two are represented,

and at corresponding intervals at its back with tubular housings 18, projecting rearwardly into the post, for spring-pressed studs 19. The other hinge-member 20, also of metal, is let into -the rounded wing-edge and may be fastened by screws,`as represented at 21. rlhis mem-ber has sockets 17a formedin its rounded Aface to register with those inthe companion-member, and is, like the member 14, bored to receive a pintle 16a; i and the member 20 is provided with'housings 18a extending backwardly from the innerends of the sockets 17a and containing, like the housings18, spring-pressed studs 192. Similar links 22 it at corresponding ends in the sockets of each hinge-member 14 and are rotatably held therein by a pintle 16, and they fit at their opposite ends 1n the sockets 17 a of the companion hinge-member 20 respectively registerin with the sockets 17. The opposite ends o each link, which should be rounded, as shown, contain depressions 23, each in position to register with an adjacent spring-pressed stud when the corresponding door-wing is in its normal ppsition, represented in Fig. 1, of radiating om a post-corner, to admit the stud into the depression for holding the wing yield ingly in that p'osition.

Chains 12 are represented in Fig. 1 as the means extending between the wings for connecting them; and each chain is shown to be permanently fastened at one end to a face of one wing and to releasably hook at its opposite end into an eye 24 on the o posing ile the intend b crowd against them, thereby overcoming the' yielding comparatively slight resistance of the spring-pressed studs or stops, and the pressure will turn those wings outwardly on their hinges to the position in which they are represented on Fig. 2, thus through 270 degrees, or thereabout; and in attaining that Y position they will, respectively, encounter the

wings

10 and 11 and turn the latter to extend as represented in that figure, thus causing all of the wings to be parallel between the sides of the casing-passageway, which thus become unobstructed.

The hinge construction, moreover, enables the rounded inner edges of the wings to meet the rounded post-corners, whereby not only the desired full extent of turning the wings is attainable, but there is no appreciable space between the meeting surfaces, so that the door, in its normal operating condition, is practically draft-proof, though the strip 13 may nevertheless be provided to effectively seal the joint.

ll realize that considerable variation is possible in the details of construction thus specically shown and described, and I do not illustrating a single specific or referre embodiment of my invention to e limited thereto; my intention being in the following claims to. claim 'protection naeaeov upon all there may be of novelty in my in- -on their hinges through approximately 270 degrees of a circle, and spring-stops on the hinge-members for engaging the link-ends to yieldingly hold the wings in their radiating position.

2. ln a revolving door, the combination oie a rotatable center-post of square cross-section having rounded corners, hinge-'members in each corner of the post, non-flexible onepiece wings having rounded inner edges, hinge-membersin said edges of the wings, said post and wing hinge-members presenting opposing sockets, links pivotally conined at their opposite ends in said opposing sockets to hold the inner wing-edges in close relation to the respective post-corners and permit the wings to be extended radially from the post-corners and to be turned, from any angle against opposite post-sides independently of each other on their hinges through approximately 270 degrees of a circle and be folded to-extcnd side by side parallel with each other, and means for releasably connecting the wings one with another in their radiating position.
