To all whom it may concern.
Be it known that I, Giusnrrn ALrANo, a subject of the King of Italy, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Elevator-Doors and Operating Mechanism Therefor, of
which the following is a specification.
A further object is to provide for con trolling a cage door or pair of doors and automatically collapsing a shaft door and turning the latter in an outward direction.
A still further object is to provide for automatically and simultaneously controlling the cage door or doors and the shaft doors, and for turning the doors last mentioned in an outward direction in the same operation, providing an unobstructed entrance to the elevator cage.
With the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described and claimed.

Fig. 10 is a section on the line 1010 of Fig. 9.
Fig. 11 is a detail view of one of the channeled members cooperating with the tripper of Fig. 9.
The mechanism for mounting and con trolling the shaft doors will first be described in connection with the construction of these doors. 1
Mounted on opposite sides of the shaft and adjacent to the doorway forming an entrance to the cage are a plurality of stationary vertical shafts designated 10 and 11, and pivotally or hingedly mounted on each of'these shafts are frames 12 and 14 in which the shaft doors are supported. Each frame carries a plurality of doors l5 and 16, the doors of oppositely located frames cooperating with each other to close the shaft opening along a central vertical line. Each shaft door comprises a plurality of members 17, 18 and 19, which are located in a horizontal position when the doors are in their closed position,that is in the position for protecting the shaft opening. Bars 17, 18 and 19 have pivotal connection with bars 20, 21 and 22 extending at an angle with the bars first mentioned, and the horizontally extending bars may be ofiset at their outer ends at a point adjacent to the pivotal mounting.
The lower bars of the upper doors are each provided with toothed members or pinions 23 rigidly mounted with reference to said bars and adapted to mesh with pinions 24: carried by the upper bars of the lower doors. The pivotal mounting of these pinions is shown at 25 and 26 and the pivotal mounting of the other bars of said doors is designated 27 The pivot members pass through the side bars 29 and 30 of each frame 12 and 14:, and said frames are pivotally or hingedly connected with vertical shafts 10 and 11 by means of apertured bracket members 31 and 32.
The pivot member 26 is provided on one ported on a vertical bar 39 secured to the spring 44.
Meshing With gear wheel 41 is a gear wheel 45 mounted on a short shaft 46 and adapted to have rotary movement imparted thereto by means of a tripper 47 cotiperating with a channel member 48 which is movable with the cage, and is provided with an inwardly flared portion 49, the flared portions of oppositely located members 48 converging with reference to each other. A stationary vertical guiding member or bar 50 is mounted in the shaft at each side and cooperates with channel member 48. The upper portions of oppositely located channels 48 may be connected by means of transverse bar 52, carried by the cage and offset at the points 53, and the lower ends of channels 48 are similarly connected by means of a bar 54 having its end portions offset at 55.
.The transverse bars mentioned are secured to the cage at points above and below the doorway. 1
Upon the movement of the cage to a proper position, the channels 48, or the end portions'thereof, engage the trippers 47 and rotate beveled gear wheels and 41, transmitting rotary movement to theframe or frames carrying the collapsible doors. This rotary movement of the frame causes the rotary movement of gear wheel 35, in view of the fact that the latter meshes with gear wheel 36 on the shaft and that said gear wheel 35 is mounted on the rotary frame and therefore moves about the axis of stationary wheel 36. The movement imparted to gear wheel 35 causes the movement of pinions 23 and 24, thereby collapsing the doors of the shaft at the time they are moved outwardly, the two operations being practically simul taneous.
The doors of the cage are similarly arranged and constructed, two of these doors on a given side of the shaft being referred to in the following description,and these doors being designated and 61. The doors 60 and61 on a given side of the cage are operated by means of a tripper 62 cooperating with a channel 63, the open side of the channel facing toward the interior of the shaft.
The endportions of the inner channels are deflected toward each other, and they are engaged by the tripper upon movement of the cage to a position opposite the doorway of the shaft The tripper 62 is carried on a short shaft 64-mounted betweenthe Sta-- tionary vertical bars 65 and 66 carried by the cage, and said shaft 64 acts under the influence of a spring 67 to hold the doors normally in a position to close the doorway of the cage. A similar spring 44 acts in I the same manner with reference to the doors of the shaft, although the spring last named acts directly to rotate the door frames and then to operate the doors.
The shaft 64 carries a pinion 72 which meshes with a pinion 73, and these pinions are rigid with reference to the upper and lower bars of the respective doors, whereby their rotation serves to collapse these doors in the manner indicated in connection with the doors of the shaft. It will be understood that the trippers operate to control the cage, a door therefor, means on the cage adapted to be engaged by means in the shaft for automatically operating the door, a collapsible shaft door mounted for movement on a vertical axis, and cage operated means for imparting a plurality of independent movements to the shaft door for opening the latter.
3. In a device of the class described, a cage, a door therefor, a rotatable and collapsible shaft door, and a plurality of rotatable devices each controlled by the move ment of the cage for operating said doors simultaneously, said rotatable devices each including meshing gear wheels and a rotatable trip imparting movement thereto.
4. In a device of the class described, a cage, a door therefor, a pair of shaft doors, each of said doors being collapsible, and means controlled by the movement of the cage for operating said doors simultaneously and a second pair of collapsible shaft doors, and means for collapsing the second pair upon the collapse of the doors of the pair first named.
5. In a device of the class described, a cage, a door therefor, a shaft door, each of said doors being collapsible and one of said doors mounted for movement outwardly, and means for effecting all of said movements automatically by the movement of the cage. I
