PIVOTING DEVICE FOR FOLDABLE REV OLVING DOORS.
'['o all whom .it may concern..-
Be it known that I, EDWARD C. HAvrLAND, a citizen of the United States, residing at 290 East One Hundred and Thirty-fourth street, New York, county of New York, and State of New York, have invented certain new and useful Improvements in Pivot-ing Devices for Foldable Revolving Doors, fully `described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention'v` relates to that class of foldable revolving doors, in which the wings which revolve within a segmental door-casing are jointed together so as to be folded iat, and thereafter moved to one side of the door-casing so as to leave an unobstructed passage through the same. tions, two of the wings are rigidly connected and projected upon opposite sides of the center bolts upon which the wings t-urn, and in the present invention transfer-bolts (or bolts upon which the folded wings may turn to be swung close to the casing) are fitted to move vertically in one of the rigid wings near its outer edge, and fitted to sockets in the floor and ceiling of the casing near one edge of the casing segment, and these transfer-bolts are connected with the pivot-bolts by mechanism which prevents the retraction of the pivot-bolts or transfer-bolts from their sockets until the others are inserted in their sockets. Vithout such a mechanism connecting the pivot-bolts and Itransfer-bolts, either might be withdrawn before the other was seated in the sockets, and the wings would then be unsupported and liable to fall, especially if a gust of wind should strike them in such unsupported condition.
By my construction, the weightof theV operative position, and in dotted lines in their shifted position. Fig 1a shows a means to suspend the wings. Fig. 2 is an elevation of the Wings removed from the casing; Fig. 3 is an elevation of one of the Specification of Letters Patent.

wings with the floor and ceiling in section, and the two sets of bolts directly connected by levers; and Fig. 4 is a similar view with a locking-bar to govern the transfer-bolts and actuated by the pivot-bolts, a portion of the wing adjacent to the pivot-bolt being broken away to show the concealed bellcrank.
.In Fig. l, a designates the usual casing formed with opposite segments; the two wings connected rigidly together, and o the :wings hinged thereto near the center so that they can be folded,as indicated in dotted lines b and c adjacent to one of the casing segments. The wings b and c are shown `1n their operative position with ties a connecting them together, with one of the rigid wings b in line with a socket d in the floor of the casing, with a transfer-bolt e fitted to such socket. `The pivot-bolts f at the center of the wings are shown movable inwardly in Fig. 3, by means of links g jointed to the bolts and to a crossbar .h which is fulcrumed upon one of the Afixed wings intermediate to its top and bottom, and provided with means for turning it when desired, in the usual manner. Packing flaps f are shown at the sides of the wings. The transfer-bolts e are shown in Fig. 3 connected with the pivotbolts f by a lever i pivoted upon one of the wings Z9 and jointed to each of the bolts by a slot j and stud 7c. When the pivot-bolts are advanced, as shown in Fig. 2, the transferbolts are retracted; and the opposite is true when the pivot-bolts are retracted. In transferring the wings to the side of the casing, as indicated by the dotted lines b', 0, in Fig. l, one of the rigid wings is moved until the transfer-bolts come coincident with their sockets d, d in the licor and ceiling, and the support of the rigid wings can then be transferred from the pivot-bolts to the transferbolts; but owing to the mechanical connection between the two, shown in Fig. 3, the pivot-bolts cannot be retracted from their sockets without advancing the transfer-bolts into their sockets, so that the wings are securely supported when the pivot-bolts are retracted. The folded wings are then in readiness to swing parallel with the side of the casing, as indicated yby the lines b, c', and remain secured by thetransfer-bolts,because the latter cannot be retracted until the pivot-bolts are swung back over their sockets and are advanced into the same.
Fig. 4 shows a locking-bar Z actuated by connection with one of the pivot-bolts, for preventing the retraction of the transferbolt from its socket; but leaving the retraction of the transfer-bolt to be effected by hand when the pivot-bolts have been proj ected, which operation retracts the locln'ngbar from interference with the transfer-bolt. The locking-bar Z is movable longitudinally across the inner end of the transfer-bolt e, and is connected with the pivot-bolt f by a bell-crank m, and is shown projected across the path of the transfer-bolt by the retraction of the pivot-bolt. The locking-bar and bell-crank are both concealed within the thickness or substance of the wing b, but the portion of the wing adjacent to the bellcrank is broken away to show its connection with the other parts.
In Fig. 8, the levers z' are shown exposed, as well as the links g which move the pivotbolts, but such parts may obviously be concealed within the door, if desired, the same as the locking-bar and its bell-crank.
In revolving` doors having foldable wings which are transferred to the side of the casing, as shown inFig. l, the weight of the wings when revolving is commonly suspended from an anti-friction journal above the upper pivot-bolt; but such arrangement is not shown in Figs. 2, 3 and 4, as the means for sustaining the weight of the doors when rotating is immaterial. I have, however, in Figs. l and la shown a means of suspending the wings detachably from a center kingbolt, the top of the wings at the center being provided with a rabbeted socket or hanger n adapted to fit a collar o upon the lower end of the king-bolt p. The king-bolt is journaled in the beam g over the ceiling e and has a socket in the lower end adapted to receive the upper pivot-bolt f. The hanger is open at one side, as shown in Fig. l, to permit the Wings to be swung off of the king-bolt when the pivot-bolt f is retracted, i
and the wings are pivoted upon the transferbolts. The bolt f prevents any displacement of the hanger from the king-bolt when the wings are arranged to revolve in the casing.
Fig. 2 shows the wings detached from the casing, to show the slight change caused in the wings by l:he addition of my improvements; the wing b at the right hand side of the figure showing the visible parts of the housings g for the transfer-bolts, and all else being concealed from view.
Having thus set forth the nature of t-he invention what is claimed herein is:
1. In a foldable revolving door, the combination, with foldable wings, of pivot-bolts at the center of the wings, transfer-bolts movable vertically in one of the wings near the edge, and mechanism controlled by the pivot-bolts for locking the transfer-bolts when the pivot-bolts are retracted.
2. In a foldable revolving door, the combination, with foldable wings, of a pivotbolt at the center of the wings, transfer-bolts movable vertically in one of the wings near the edge, and mechanism connecting the pivot-bolts and transfer-bolts, for retracting one when the other is advanced.
3. In a foldable revolving door, the combination, with foldable wings, of a pivotbolt at the center of the wings, transfer-bolts movable vertically in one of the wings near the edge, means between the top and bottom of the door for projecting the two pivot bolts simultaneously, and means connected with the two pivot-bolts for simultaneously imparting a reverse movement to the transfer-bolts.
. 4. In a foldable revolving door, the com- EDWARD C. HAVILAND.
