reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a new and useful improvement in elevators, and particularly to that class known as passenger-elevators, although from the following description it will be seen-that it is applicable to all elevators wherein a person is obliged to ride in order to manipulate the same.

,The object of this device is to insure to a great extent the. safety of a person within the elevator should any of the mechanisms employed in the operation of the same become elevator to descend in a rapid or dangerous manner.y

Figure I is a perspective view of a portion of an elevator-shaft, a cage arranged therein, and my invention applied 'to said shaft and cage. Fig. II is a vertical longitudinal section through a portion of the shaft and cage, the view )eing taken through the doors thereof.

A represents an elevator-shaft of usual construction, which is provided with the ordinary sliding door a.

B represents the cage or elevator proper, which is designed to traverse the interior of the shaft A in a manner well understood. This cage is composed of a iioor 1, side walls 2, back wall 3, front wall 4, and a roof 5, and

`attached \to said cage in any well-known manner areJ the operating-cables 6. The front wall 4 of this cage B is provided with a door-opening b, which is designed to register with the door-openings closed by the door a of the shaft. This door-opening b is entirely open at its upper end-that is, there is no upper frame member-and formed in the roof 5 of the cage is an opening or cut-away portion 7, which opening forms practically a continuation'of, the door-opening b, but is disposed approximately at right angles thereto. 8 designates a trap-door, hinged at 9 to the roof 5 of the cage, and is designed under ordinary conditions to cover the opening 7, whereby a complete roof for the cage is provided.

10 indicates a plurality of preferably horizontally-disposed rungs, arranged within the Specication of Letters Patent.

shaft A, and are so positioned as to be out of the path of travel of the cage B, but are directly opposite the door-opening b and the roof-opening 7'. These rungs are located at suitable distances apart and between the upper end of the opening closed by the door a of one lio'or of a build ing and the lower end of the door of the floor of the building there next above.

In the event of the cage starting to fall too rapidly, due to some accident to its operating mechanism, an occupant being fearful of his safety will reach his hands outwardly through the door-opening b of the cage and grab hold of some one of the rungs 10, doorframe, lattice-work, or sill of the door a, holding on thereto while the cage descends, which action on the part of the occupant will cause his arms or head to contact with the tra -dcor directly above him, o en the same, an permit the entire body of tl e said occupant to pass through the cage unharmed, where he may remain until assistance reaches him.

In order that each occupant, should there be more than one, will not have to successively open the trap-door with his arms or head, as above described, I have arranged a simple device whereby when the door has been once opened itwill remain in such condition until it is manually closed. This device consists of a counterweight 1.1 so posi- -tioned on the trap-door that its weight when the door is closed tends to keep it in such position. However, after the door has been opened this weight is thrown to such position that gravity will cause it to hold said trap-door in the aforesaid desired position.

In order to prevent bruising or otherwise injuring the occupant, I make this trap-door of any very light material, such as thin wood or aluminium, which.,can be opened without offering but very little resistance.

Obviously the trap-door and rungs can be utilized should the cage sto between iioors by the occupants in ascen 'n to the floor above, and after said cage has een emptied of its passengers all necessary repairs to the cage, shaft, &c., can be made without endangering persons lives.

While I have shown the trap-door as extending only over part of the top of the cage, it will be understood that I may in some cases extend this door over the entire width of the -cage.
