- the wings 21 of the door are suspended, and said wings, pillar, and all of the appurtenances of the revolving door structure are hung from and supported by the two-part central shaft made up as hereinbefore described of the hanger shaft 6 and the foot shaft 14, and obviously this central hanger shaft is carried by the truck 3 and its hanger 4, said truck revolving upon suitable rollers traveling over a circular track arranged on the cross-beam 2.

- a sheave-stmporting disk or web 45 secured within the bore of the pillar B and carrying the small sheaves 46 about which reversely pass the pull cords 17 of the locking plates, the ends of these cords being fastened to posts 48 carried by a disk 49 rotatablyanounted upon a bearing sleeve on the central hanger shaft as best shown in Fig.
- Said disk has connected thereto a pull cord 50 which is led through the pillar B to a suitable point, said pull cord 50 preferably passing over a tixed sheave 51, so that when the cord. 50 is pulled, the disk 4-9 will be rotated, the lock plate pull cords 4-7 will be sin'lultaneously pulled and the lock plates withdrawn, simultaneously releasing the wings which may then be moved to collapsed position.
- Each wing 21. is provided with a two-part pivot bolt 57 mounted near the outer edge of the wing 21, as clearly shown in Fig. 1, and provided with an operating device, such as a turn buckle 58, or any suitable projecting instrumentality, by means of which the ends of the two members of the pivot bolt 57 may be projected beyond or withdrawn within the top and bottom edges of the wing 21.
- the door and ceiling of the passage-way are each provided with a socket- 59 to receive the ends of the pivot bolt 57 when they are projected, these sockets 59 being located preferably as shown in Fig. 2, at the side and within the fixed curved side frame A of the doorway. ⁇ Vhen it is found desirable to remove the door from its central revolving position, one of the wings 21. will be swung to the angle where the pivot bolt 57 will register with the ceiling and floor sockets 59, whereupon the ends of the pivot bolt will be projected by means of the turn buckle 58 or other bolt operating device to engage these sockets.
- This arrangement is a very desirable one for the reason that the entire door structure can be quickly and easily thrown to one side out of the way and leave the passage-way entirely unobstructed, without the necessity of removing the door parts bodily from the doorway, but, on the contrary, leaving them in readily accessible posit-ion where they may be quickly installed in service again.

DAVID M. QUAY, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, 'I'O VAN KANNEL REVOLVING DOOR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
To all whom it may concern:
Be it known that I, I)A\Il) M. QUAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Revolving Doors, of which the following is a specification.
The present invention relates to doors, and particularly to that type now generally in use in vestibules, entrances, and the like, and conunonly known as revolving or turnstile doors.
The invention has for its objects: First: To improve the construction of such doors and the appurtenances for mounting and handling them. Second: To provide a door which will, under panic conditions, automatically yield to undue pressure, collapse to an open position, and leave a free passageway. Third: To provide a door which may be readily collapsed by an attendant or doorman, either at the door or at a distance therefrom, when such collapsed condition is desired. a
In the accompanying drawings I have illustrated one embodiment in order that the same may be clear to those skilled in the art, the various views detailing such features as are essential to the make-up and operation of the structure.
In said drawings,-Figure 1 is a general view of an arch or doorway having installed therein a revolving door embodying my improvements. Fig. 2 is a plan View showing the door members proper in active and collapsed condition in dotted lines. Fig. 3 is an enlarged detail, partly in section, to show the manner of hanging the door. Fig. -11: is a detail crss-sectional view of the central pillar and hanger, showing the hangeroperating gear and associated parts. Fig. 5 is a plan view of the pillar top, showing the lower half of the supporting race for the door members proper or wings, the normal position of the doors being shown in full lines, the dotted lines showing collapsed condition. Fig. 6 is a view similar to Fig. 5,
showing a slightly different form of wing. race. Fig. 7 is a sectional View showing a modified race. Figs. 8, 9 and 10 are detail views of wing locks to maintain the doormemloers or wings normally in proper posi- Specification of Letters Patent.

tion. Figs. ll and 12 are top and sectional views, respectively, of a slightly different form of wing lock. Fig. 15 is a sectional view showing one type of manually releasable wing lock. Figs. '14-, 15 and I6 are views showing a plurality of wing locks which are releasable manually simultaneously. Fig. 17 is a detail of the wing look ing bolt and turn buckle or nut.
In the description which follows the same reference characters are used to designate like parts in the several views.
The general structure of door and frame is not unlike those commonly in use, compris ing the usual curved side frame A, the central pillar I3, and the door member's or wings C which radiate, quartering, from the central pillar B. Except for these general similarities, however, the present structure di'tlers markedly from doors of this type with which I am familiar.
The arch or door-frame comprises the curved side frames A which arespanned by a cross-beam 2, centrally of which, depending from a rollerbearing truck 3, is a hanger 4, preferably adjustable by a screwthreaded and splined connection with relation to said truck. all as shown in Fig. 3. Secured to the lower end of said hanger 4, by a detachable connection, such as pin 5, is a supporting shaft (5 which lies centrally of the pillar IR and is splined near its upper end to a wing-race supporting-web 7 secured within the bore of the hollow pillar It, as best shown in Fig. 3. The lower end of the shaft (3 may be offset, as shown in Fig. 3, and is toothed so as to mesh with a gear 8 on a shaft 9 carried in suitable bearings within and intermediate the ends of pillar B (see Fig. 4t) said shatthaving a head l0 at its outer end pocketed within the enlarged shaft hearing or sleeve, to receive a wrench or other tool by which it may be turned and the gear 8 rotated; and, to lock said shaft 9, a ratchet 11 and pawl 12 are provided, said pawl 12 being mounted on pivot shaft 13 which may be rocked by its slotted head from outside the pillar B to throw the pawl 12 in andv out of the ratchet 11. Opposed to the offset, toothed lower end of hanger shaft 6, is a similar foot shaft 14 having an offset toothed end, which, ogether with the lower end, of
From the pillar B the wings 21 of the door are suspended, and said wings, pillar, and all of the appurtenances of the revolving door structure are hung from and supported by the two-part central shaft made up as hereinbefore described of the hanger shaft 6 and the foot shaft 14, and obviously this central hanger shaft is carried by the truck 3 and its hanger 4, said truck revolving upon suitable rollers traveling over a circular track arranged on the cross-beam 2. The wings 21 are provided at top and bot tom with arms 22 tipped with ball members 23, which ball members are clamped between the lates of the wing races 24 at top and 18 and 24 at the bottom of the pillar.
In the form of the invention shown in Figs. 1, 5 and 6, I have shown the ball members 23 as carried by the arms 22 and the race plates as being formed to receive these members, but obviously as shown in Fig. 7 the construction might be reversed and the race consist of the ring-like plate 23 while the arms of the wings would be made up of complementary top and bottom plates 24 of the contour to engage the ring race 23*.
The wings 21 are, of course, under normal conditions ninety degrees apart about the pillar A as shown in Figs. 2, 5 and 6, and the whole structure under ordinary traflic revolves as a unit. The wings 21 are locked tothapi-l'larso asto give a unitary revolving device by means of locking plates 25, as shown in Fig. 8, which shows the locking plate 25 carried by a shaft or rod 27 mounted in a suitable aperture in-the pillar B, said plate 25 being normally projected in the position shown by a spring 28 of suflicient strength to hold the plate 25 projected from its pocket and in engagement with the wing 21 and capable of holding such wing against independent movement relative to the pillar 13 under the conditions of ordinary traflic. If, however, undue and opposing pressure, as in a crush or panic, be brought to bear upon the opposite wings 21 of my improved door, the locking plates 25, see Fig. 5, will yield and thewings 21 move independently relative to the pillar B,
to the position shown in dotted lines in the upper half of the Fig. 5 referred to, the balls 23 traveling along the wing races under pressure to the dotted line collapsed position, it being obvious that only such wings as lie transversely to the passage-way would be collapsed, although in event of all of the wings 4 being crowded around by pressure against them all four would ultimately be brought to the dotted line position shown in the lower half of Fig. 5.
In order that there may be no danger of jamming the wings 21', the ball race 24, see Fig. 5, is not made in the form of a true circle, but is in the nature of a flattened circle or lobe shaped, giving the appearance of a polygon having rounded sides as shown, so as to permit a substantially straight travel of the ball 23 in moving from its normal to its collapsed position, and prevent any jamming of the wing 21, as might be the case if the race were struck on a true circle, there being sufficient clearance with my improved race between the inner edge of the wing and the side of the pillar to insure collapsing of the wing without jamming against the pillar as will be clear from the dotted lines as in Fig. 5, which shows the wing 21 moving from its normal full line position to collapsed dotted line position.
In Fig. 6 a slightly different form of race is shown from that described and shown in Fig. 5, the inclosing walls of this race or course for the most part being straight walls instead of curved as in the other form, although in principle andin operation the race is the same, and, as will be seen, it is not a circular but is rather a flattened circular form, or one which approaches a rectangle. This feature of a non-jamming wing supporting race I regard as 0f-c0nsiderable importance, for it permits hurried displacement and collapsing of the wings by a crowd endeavoring to pass through the door without danger of such wings jamming and blocking the entrance.
The locking plates which hold the wings normally in the full line position shown in the various views may, of course, take several forms, and in Figs. 9 and 10 I have shown a side lock for engaging the inner edge of the wing 21 which comprises a boX 29 let into the pillar B and having a locking plate 30 which has slot engaging lugs adapted to drop into and lie within the bayonet slot 31, this block being backed by spiral springs 32 housed within suitable cases 33. These lock plates for holding the wings in normal position may be located in the sides of the pillar B as shown in Figs. 1, 5, 8, 9 and 10, or as illustrated in Figs. 3, 6, 11, 12 and 13, they may be located in the top of the pillar and engage the arms 22 of the wings 21, and obviously their looking and retaining action will be the same as the action of the locking plates just de scribed. In the form of locking plate shown in Figs. 3 and 6, the plate 34 is mounted in a suitable recess 1n the pillar with a proj ecting spring beneath it to hold it in locked engagement with the arm 22 of the wing,
the tail of the plate being slotted and pinned as shown at to its seat.
In the form of the top locking plate shown in Figs. 1.1 and 12, the plate 36 backed by spiral springs, as shown, is mounted within a box or holder 37 let into the top of the pillar B.
The locking devices heretofore shown and described have all been arranged to release automati ally under undue pressure, but in some instances it may be desirable to provide locking plates which may be operated by the attendant, when, for example, he wishes to collapse the wings and leave the door open, and in order that a suitable construction to accomplish this may be provided I have devised several ways of securing a manual release of these locking plates, although it will be understood that this manual release fea ture is additional to the automatic release under undue pressure on the wings, and in no way interferes with this automatic release. The simplest form of this manual released locking plate is shown in Fig. 13 in which the locking plate 38 of the top lock type let into a suitable seat in the pillar B, and the tail of the locking plate drops down to a cavity or opening 39 in the side of the pillar where it is provided with a bail 40 which is accessible on either side of the wing 21 (shown in dotted lines) so that an attendant may reach into the cavity 39 and pull down on the bail 4:0 to withdraw the plate 38 and release the wing. This, of course, involves the individual operation of each locking plate, and in order that these locking plates may be operated in pairs I have devised the construction shown in Fig. 1 1- in which the side locking plates 41 are let into suitable seats in the pillar B, such looking plates 41 being connected by suitable cords 42 with a pull cord or handle 43, proper running sheaves being provided over which these pull cords -12 pass, these running sheaves being mounted on a block 44: secured to the central hanger shaft hcreinbet'ore described. It will be obvious that with this construction the doors on diametrically opposite sides of the pillar may be simultaneously released by simply pulling on the cord 43 and through the pull cords 12 withdrawing the locking plates 11 into their pockets.
In the form of release device shown in Figs. 15 and 1G, I have made provision for sin'niltaneously releasing all four or any number of wings with which the door may be provided. As shown in these figures, I provide a sheave-stmporting disk or web 45 secured within the bore of the pillar B and carrying the small sheaves 46 about which reversely pass the pull cords 17 of the locking plates, the ends of these cords being fastened to posts 48 carried by a disk 49 rotatablyanounted upon a bearing sleeve on the central hanger shaft as best shown in Fig.
1.6. Said disk has connected thereto a pull cord 50 which is led through the pillar B to a suitable point, said pull cord 50 preferably passing over a tixed sheave 51, so that when the cord. 50 is pulled, the disk 4-9 will be rotated, the lock plate pull cords 4-7 will be sin'lultaneously pulled and the lock plates withdrawn, simultaneously releasing the wings which may then be moved to collapsed position. In order that the simultaneous release of these wings may be accomplished from a distance 1 have provided a pull spring 52 ot' sullicicnt strength to overcome the lock plate springs, said spring 52 being secured to the drum and to the disk elf), and being normally distendcd and held in active position by a tie connection 53 which carries a :t'usible section 54., which -fusible section is in circuit with an electric line ot' sullicient power to fuse the connection when the line 55 is closed, such line being conventionally shown in Fig. 16. \Vith this arrangement an attendant at a distance from the door may, by closing the line 55 through the switch 56, destroy the fusible section 54, releasing the tie connection 53, and allowing the spring 52 to rotate the disk 4-!) and withdraw the locking plates.
In order that the dooiymay be taken down readily and removed to one side of the passage-way, as for example, in warm weather, when closing of the passage-way is not necessary, I provide a convenient means for securing this taken-down condition, which means is best illustrated in Figs. 1 and 2 of the drawings. Each wing 21. is provided with a two-part pivot bolt 57 mounted near the outer edge of the wing 21, as clearly shown in Fig. 1, and provided with an operating device, such as a turn buckle 58, or any suitable projecting instrumentality, by means of which the ends of the two members of the pivot bolt 57 may be projected beyond or withdrawn within the top and bottom edges of the wing 21. The door and ceiling of the passage-way are each provided with a socket- 59 to receive the ends of the pivot bolt 57 when they are projected, these sockets 59 being located preferably as shown in Fig. 2, at the side and within the fixed curved side frame A of the doorway. \Vhen it is found desirable to remove the door from its central revolving position, one of the wings 21. will be swung to the angle where the pivot bolt 57 will register with the ceiling and floor sockets 59, whereupon the ends of the pivot bolt will be projected by means of the turn buckle 58 or other bolt operating device to engage these sockets. After this operation has been effected the other wings 21 will be collapsed, as hereinbefore described, the hanger shaft 6 will be disengaged from the lower end of the hanger 4L by removing the pin 5, and the said hanger shaft 6 will then be run down- &
Ward so as to clear the ceiling of the doorway by means of the gear 8 hereinbefore described. This will leave the pillar free at the top and resting upon its foot shaft 14, which foot shaft may then be lifted from its socket 20 in which it normally rests, and the central pillar with its collapsed wings may be rolled upon the ball foot '19, swinging about the pivot bolt 57 as a center, until the entire collapsed door structure will be brought to the position shown in Fig. 2 in dotted lines, at the right hand side of said figure, housing all of the parts within the side frame of the doorway and leaving the passage clear. This arrangement is a very desirable one for the reason that the entire door structure can be quickly and easily thrown to one side out of the way and leave the passage-way entirely unobstructed, without the necessity of removing the door parts bodily from the doorway, but, on the contrary, leaving them in readily accessible posit-ion where they may be quickly installed in service again.
