SPECIFIGATION forming part of Letters Patent No. 521,086, dated June 5, 1894.

Original application led August 3l, 1893, Serial No.484,46`2. Divided and this application filed May 12l 1894. Serial No. 511.041. (Ne model.)

To all whom t may concern.-

Beit known that I, ROBERT W. HABE, a citizen of the United States, residing at Allegheny, inthe county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in fire doors to cover the hatch-ways of elevators.

The object of the invention is to provide novel means whereby the doors of several floors may be carried Aon top of the elevator car, and stored at the top of the elevator shaft; furthermore, to so construct all the parts of the mechanism that the operation, of storing the doors on the supports and lreleasing the same, will be entirely automatic.

With these objects in view the invention consists in novel combinations and arrangements of parts to be hereinafter more particularly described and specifically pointed out in the claims.

The machine 'is especially designed and adapted to be used on side-post elevators, yet with slight changes it may be operated on those having corner posts.

The invention is also particularly applicable to elevators of high speed, but it can be operated equally as well on slow speed or freight elevators.

In describing the invention in detail reference is had to the accompanying drawings, forming part of this specification, in which like numerals of reference indicate corresponding parts in the several views, in which- Figure 1 is a view in front elevation of an elevator shaft, showing the doors landed in position at their respective floors. Fig. 2, is a similar view showing the doors resting on the vhangers at the top of the elevator shaft. Fig. 3, is a view in side elevation partly in section, showing the arrangement of the door hangers, the supports for the doors and their operating mechanism on the car being omitted. Fig. 4, is a detail view ofthe releasing mechanism arranged to the side-post of the elevator shaft. Fig. 5, is a view in side elevation representing the mechanism of the slidp ing bar retracted and showing in dotted lines the position ofthe same when retracted. Fig. 6, is an enlarged detail view of the mechanismv arranged to the side post of the elevator shaft corresponding with Fig. 4, but more clearly illustrating a different position.

In the drawings 1, represents the side posts of an elevator shaft; 2, the elevator car; 3, the fire doors; 4, the guides attached to the sides of the elevator car for the reception of the adjustable upright standards or supports 5, which form a support for the doors .while riding with the elevator car, vsaid supports being adj ustable through a horizontal leverY 6, pivotally secured at 7, to the sides of the elevator car, while at its opposite end an arm 8, is secured, which has notches 9, 10, for the reception of the stationary pin 11. To the horizontal lever 6, are pivotally secured near its center, links 12, forming aV and carrying levers 13 fulcrumed at 14 and engaging the said supports 5.

The numeral 21, represents a recess in one of the side posts which contains the spring 22, pivoted at 23, and working against a spiral spring 25, and a bolt 26, extending and operating through an aperture 27, in the side post; embracing the side posts are anti-friction guides 28 and 28%, having rollers 29, and inwardly extending portions 30; onl the outer face of the guide 28 is a transverse slot 31, also a hinged support 31%, which operate in conjunction with the guide, which also carries on its outer face links 32, forming with the links 33, a diamond as shown in dotted lines (Fig. 5) of the drawings. 32, are secured together by a pivot 34, said pivot extending into and being movable in the slot 31. At the opposite end the links 32, are pivoted to other links 33, as at 35, and

These links also to the supports 36, whichoperate through which is the usual mode of supporting doors roo of this class.

For the purposes of a clear explanation as to the modus operandi of this device, let us suppose the doors are all in position at the landings (as shown in Fig. 1,0f the drawings) and itis desired to place them on the supports. The door supports on the elevator car are raised to the maximum limit by the engagement of the pin 11, with the notch 9, of the arm S, when the elevator car is started, and as the supports come in contact with the doors which ascend on to'p of the standards or supports, the doors are carried to the top of the shaft and while ascending, the top fioor comes'in contact with the anti-friction guides 2S which retract the supports 3G, and the side of the elevator car depresses the spring 22, which is arranged in the path of its travel and thus forces the bolt 26 out through the side post and forms a seat for the hinged support, the latter riding above the bolt. Then the elevator car reaches this point the doors are above the supports 36, and the latter having been retracted so as to pass under the doors as described above, on the ascent of the car door, as the elevator car. is lowered, secure the doors. The supports 36, are prevented from returning to their normal position at this time on account of the support 31-1^, resting on the bolt 26. The lower door 1s provided with apertures in its under side for the reception of the pins 39, on the supports 36, preventing lateral motion of the said supports. As the elevator car descends in its course below the spring 22, the spiral spring 25, which has been depressed takesits normal position forcing the spring 22, inwardly and with `it the bolt 26, which forms the rest for the hinged support 3l-; this will allow the latter to drop a short distance as illustrated in Fig. 4c, while the doors are held in position on the support by the force of gravity and the pins 39 heretofore referred to, while the elevator car returns to the ground iioor and the supports 5 thereon are lowered to aposition levelwith the beam of the elevator car. While so adjusted, the car may run up or down without disturbing the doors, it being understood that a stop is securedon the operating cable at a suitable distance fromv the top to prevent the cars ascending sufliciently to disturb the doors when the supports 5 on the car are lowered. When it is desired to close the opening 0n the elevator shaft, the supports are'adjusted to the next notch 10, and the elevator car ascends to the top ioor of the building, engages the doors and lifts them above the supports. The guides 28 however with this adjustment are not raised far enough to bring the lower edge of the support 313,-, above the bolt 26. The supports 36, retract automatically by reason of the gravityof the mechanism, after the supports are removed, the doors are allowed to descend with the elevator car and at the several landings are arrested as heretofore explained. The entire operation is simple and wholly automatic.

Particular attention is called to the fact that in an emergency, or in case of coniiagration, the elevator car may be run to the top of the building to carry down the doors without the aid of a person accompanying the elevator car.

It will be understood that various changes may be made in the detail construction of this device without departing from the general idea involved. v

An application iiled by me Augustll, 1893, Serial No. 484,462, contained a description of the device herein claimed, this application being a division thereof.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. In an elevator, the combination with a car having adjustable supports or standards adapted to carry a series of doors,ofa device for supporting said doors at the top of the shaft,and means for automatically extending and automatically withdrawing said device when the doors are raised from engagement therewith, substantially as described.

2. In an elevator, the combination with a car having supports or standards, of a series of hatch doors adapted to `be carried there by, a device for storing said doors at the top of the shaft, and means for automatically retracting and automatically extending the device, substantially as described.

In an elevator, the combination with a car, of a series af hatch doors adapted to bc carried on the top thereof, a device at the top of the shaft adapted to receive the doors, and

IOO

means for automatically retracting and autoy matically extending said device, for the purpose described.

In testimony whereof I aix my signature in presence of two witnesses.
