To all-whom it may concern: 1
Be itknown that I, HARRY W. DYER, a citizen of the United States and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Revolving Doors, of which the following is aspecification. i
This invention relates to revolving doors in whichthe leaves of the door collapse to provide an open passage and has for an object to provide a novel type of hinge for the door leaves whereby they can be collapsed from any position and folded together like the leaves of a book, also a construction of this jkind which is comparatively inexpensive to construct and readily collapsed and opened to the operating position. These and other objects; of the invention will be understood from the following specification and the accompanying draw- F 1 is an elevation'of a revolving door of the standard type embodying my invention;

Fig. 9 is an end elevation of the latching and pivot mechanism; and
Fig. 10 is a side elevation ofthe latching and pivot mechanism.
Revolving; doors of the class described have a central shaft supporting the leaves which revolve about this lcentre within a vertical cylinder the opposite sides of which are cut away to form the entrance. necessary that these leaves be capable of folding together so as to provide a clear open passage through the entrance in case of panic or in hot weather when an open passage is desirable; it is also desirable that the leaves be released between any pair and folded together from any position.
One way of securing this result heretofore used was to provide a plnlon gear around the central shaft and to mount hingeplates or discs on this shaft. The door leaf is pivoted 011 the hinge plate out from the centre and has a gear quadrant engaging with the pinion. This pivot is not fixed but is capable of moving in a circle about the centre shaft so that the leaves can rotate I about the centre, at the same time the leaves are capable of pivotal action which is, guided by the quadrant engaging the pinion on the shaft. This invention eliminates the use of the pinion and quadrant and the movable pivot, thereby reducing cost and friction and providing a construction that is positive in action.
Referring to the drawings, 11 is the cylindrical casing of the revolving door construction, 12 designating the revolving door mounted to revolve uponthe vertical shaft 13. The door as shown 1-11 Fig. 2 comprises four leaves 14, 15, 16 and 17 which are 7 pivoted on the pairof hinge plates 18 and 19 at the top and on the pair of hinge plates 20 and 21 at the bottom. These leaves are spaced 90 apart by the flexible connections 22. i This is a standard construction in revolving doors in which the number of leaves may be varied.
- Referring to Fig. 4 it will be noted that the collar33 on shaft 13 supports the top hinge plates 31 and 32 indicated at 18 in Fig. 1 and immediately below this another pair of hinge plates 34 and 35 indicated at 19 in Fig. 1 are supported in the same way by collar 36. A separate hinge plate is provided for each door leaf at the top and bottom of the door. From the sectional drawing in Fig. 4 it will be noted that these hinge plates are mounted on ball bearings and are hollowed out so that they rotate with comparatively little friction. All these plates are alike except for the bearing so that they can be quickly machined.
The plates are provided near their outer edges with holes as indicated at 37 and 38 inFig. 4. The pivots 40 in the door leaves are inserted in these holes as hereafter described. Each plate is alsoprovided with anzarcuate groove 41 concentric with the holes 37 and 38. On a radial line joining the holes with the centre this groove is depressed as indicated at 42 to receive the locking pin 43. It will be understood from the dotted outline in Fig. 3 that the hinge plate for each leaf has a corresponding arcuate groove and is provided with a pivot hole and a locking pin similar to that just described. W hen the locking pin 43 engages the groove 42 the hinge plate is rigidly locked to the door leaf and may rotate therewith about shaft 13. When the pin 43 is moved out of groove 42 then the leaf is free to move about the pivot 40 to the extent of the movement of pin 43 in groove 41. This enables the. leaves to fold against each other.
Fig. 5 shows the position of the door leaves when they are all folded in the same direction, however, the outer leaves 14 and 1.5 may be folded in the opposite direction to leaves 16 and 17 as indicated in dotted outline at 14 and 15.
In Fig. 7 it will be noted that the leaf 17 is pivoted to the hinge plate 31 at- 40 and has the locking pin 43 movable in the groove 41. This pin is engaged by a motion plate 51 which is guided by the fixed pin 53 in the slot 52 and slides in the mechanism. The inrlined plane 54 of this motion plate engages the locking pin 43 and forces it out of the locking groove 42 as the motion plate is forced into the door leaf. This releases leaf 17 so that it can turn on pivot 40 and swing in either direction with pin 43 mov ing in groove 41. The motion plate 51 is forced under pin 43 when the adjoining leaf i6 is moved towards 17 these parts engaging as indicated at 56. Continued movement of 16 towards 17 after pin 43 is released causes 17 to move on the pivot 40 and a corresponding unlatching of leaf 16 is effected so that these two leaves become parallel as indicated in Fig. The motion plate moves under motion plate 51 and has a similar action with reference to a door leaf moving towards 17 in the opposite direction.
The action just described shows what takes place on hinge plate 31 to which the leaf 17 is pivoted. It is apparent, however that moving 16 towards 17 is equivalent to moving 17 towards 16 and a similar action takes place on the hinge plate to which 16 is pivoted, thus simultaneously unlocking the leaf 16 by its engagement with 17 as 17 is unlocked, these two leaves thus become free to move to a parallel position together as indicated in Fig. 5. The leaf 14 may now be moved around with the hinge plate until it is unlocked by engaging 16 when it can be moved on its pivot 40 to a position parallel with 16. A similar condition applies to leaf 15 so that all the leaves become parallel as indicated in the drawing.
The folded position of the door leaves relative to the center is illustrated in Fig. 6. The normal line of the leaf is indicated by a. The pivot 40 of leaf 16 or leaf 17 is moved by rotating the hinge plate to the line 0 which is parallel with a; and is therefore the line of the locking pin which rests in groove 41 at 58. The groove may, if desired, be slightly shouldered here as illustrated in Fig. 6 so that the shoulder checks the movement of the leaf. This groove, it will be noted is similar on both sides of the centre line b so that the leaves can swing in both directions on pivots 40.
The outside leaf 14 has the pivot pin swung to the position 40 on line 6 which is parallel with line a. hen in this position the locking pin is at the end of the groove as indicated in Fig. 5. The door leaf can thus swing on pivot 40 through the angle enclosed by the lines (Z in Fig. 6; as it swings it is automatically latched to the hinge plate when on the center of the groove and its movement is retarded at the position indicated by the lines 0 as the locking pin travels in the groove. Any of the flexible connections 22 may be released by unlatching their ends from the door leaves and any leaf may be rotated about the center 13 on its hinge plates independently of the other leaves and when two leaves engage as in Fig. 7 their latches are released.
The locking mechanism as illustrated in Fig. '8 is mortised into the door and is held in position by the cover plate 67 and screws 68 and 69. This mechanism comprises the casting 61 which supports the pivot pin 40. This pin is held in position by the set screw 66. The outer end of this casting is formed into a pair of jaws (SQ-62 which guide the sliding block 63 so that it has a longitudinal movement equal to the distance required for the locking pin to ride in slot 41. This block carries the locking pin 43 which is held in position by the set screw 64. The coil spring 65 normally moves the locking pin towards the pivot 40 so that this pin latches in groove 42 as the leaf is brought to the center. The groove 42'may be so formed that excessive pressure on the door will force the pin out of this groove or it may be formed so that the pin must be forced out of the groove by exterior means, either method of construction may be desirable to meet speciiic requirements. The motion plates 51 and 55 are placed on different vertical planes and engage the pin 43 as shown. The door leaf is placed in position by removing the cover plate 67, raising pins 40 and 43, setting the door on its hinge plates, moving the pins into the grooves and replacing cover 67.
From Fig. 4 it will be noted that the door leaves are mortised out to receive the hinge plates and that one hinge plate receives the pivot mechanism from the top and the other motion plates on the adjoining leaf.
The door leaves are moved from the collapsed to the operating position by swinging on the pivot 40 until the locking pin is latched in the groove and by moving the hinge plates to position when the connections 22 are secured.
