ELEVATOR-DOOR-OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 476,773, dated June 14, 1892.

Application filed December 12, 1891- Serial Na. 414,856. (No model.)

T0 all whom it nuty concern:

Be it known that I, GEORGE NV. ARCHER, of Rochester, in the county of Monroe and State of New York, have in vented certain new and useful Iinprovernents in Elevator-Door- Operating Devices; and l do hereby7 declare the following to be a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures of reference marked thereon.

My present invention has for its objects to provide a device for Operating the doors of elevator shafts or Wells, whereby the move- Inent of the car or cage will serve to open the door when it approaches a fioor, maintain it open while the car is standing there, and close it again positively when the car inoves in either direction; and to these and other ends the invention consists in certain novelties in construction and combinations of parts, all as will be hereinafter described, and the novel features pointed out particnlarly in the clai ms at the end of this specification.

In the drawings, Figure 1 is a view looking from the shaft toward the door, showing the Operating devices in the well and on the car. Fig. 2 is a horizontal sectional view on 'the line w x of Fig. 1; Fig. 3, a side view of the devices on the car and well; Fig. 4, a sectional view on the line y y of Fig. 1.

Similar reference-numerals in the several figures denote similar parts.

The car or cage 1 of the elevator may be of the ordinary or any preferred construction, upon the front side of which is arranged a standard 2, said standard having at top and bottom bearings for a shaft 3, to which is connected a rack at by arms 5 and G,the latter being continued rearward and downward, forming an Operating handle or lever for turning the rack and shaft to the positions shown in full and dotted lines, Fig. 2. A spring 7, connected to the lever G and Operating on the standard, tends to move the rack into the position'shown in dotted lines, Fig. 2, out of engagement with a gear-wheel, farther on described.

The door 8, one being arranged at each floor, may be of any desircd construction, though I prefer to make it, as shown, of strips 9, secured to a backing 10, of canvas or similar flexible material, and to provide guides 11,in which it runs, extending upward and forward, as shown, said door being counterweighted or supported on spring sash-balances, so that it will require little power to run it.

Arranged at the side of the door-opening and within the well is a plate 12, having a lug 13 at one side, and upon a bolt or pin 20, extending through this plate, is pivoted a gear 111, having a crank-pin 18 thereon connected by a connecting-rod or ptrnan 15 with the door 8. In the present instance this connection is formed by a lever 1G, pivoted at 30 in the well, connected at one end to a link 31, pivoted to the lazy-tongs 17, which is in turn fastened to the lower end of the door and at the other to the pitinan 15, the arrangement being such that when the Crank-pin on the gear is in lowest position, as in dotted lines, Fig. 1, the door Will be open, and when in highest position it will be closed.

The rack 4, located on the car, is preferably beveled at the ends, as shown in Fig. 3, and the space between the lug 13 on the plate 12 and the edge of lthe gear is such that when the rack is turned so as to engage the gear the lu g 13 will hold it in engagement against the tension of the spring 7 until it has moved out of engagement, when the spring will move the rack to the position shown in dotted lines, Fig. 2. Normally the rack on the car is in the position shown in dotted lines, Fig. 2, the door is closed, the pitman 15 being in line with the center of the gear and the wrist-pin above thev center, so that it is impossible to open the door eX- cept from withinthe Well, and the car can be raised and lowered without Operating any of the doors in the well. VVhen the operator in the car wishes to stop at any floor, just before he reaches it he moves the handle 6 so that the rack will be in position to engage the gear and holds it there until the beveled end Strikes the lug 13, which latter will hold it in engagement with the gear, and the continued movement of the car Will rotate the gear a halfturn, which will be accomplished When the car is level with the floor, when the car may be stopped in the ordinary manner. The lug 2 v wawa 13 holds the rack in engagement and prevents the closing of the door until the car moves away, and then, no matter' in which direction it moves, the gear will be rotated a half-turn 5 and the door closed and locked as before.

Instead of having the spring 7 hold the rack out of engagement, it could as well be made to hold it in position to engage the gear, in which event all the doors would be opened and closed by the car unless it were desirable to pass them. l/Vith this arrangement there is no possibility of the doors being left open accidentally or of the doors being closed when the car is at the floor.

The device shown herein is simple, easily operated, and, I find in practice, admirably adapted for the purpose.

I claim as my invention- 1. The combination, With an elevator-car and the movable rack thereon, of a door leading into the elevator-Well, a gear connected therewith, With which the rack engages and adapted by its rotation to operate said door, and a stationary projection in the well co-operating With the rack and retaining it in engagement with the gear While the car is in proximity to the door, substantially as described.

2. The combination, with an elevator-car and the rack pivoted thereon, of a door leading into the well, a gear connected thereto, with which the rack engages and adapted by its rotation to operate said door, and a stationary lug in the Well co-opcrating with the rack and retaining it in engagement with the gear while the car is in proximity to the door, substantially as described.

8. The combination, with the door 'leading into the elevator-\vell,a gear connected thereto and adapted byits rotation to operate said door, of an e1evator-car,a movable rack thereon, a spring for moving the rack out of engagement with the gear, and a stationary projection in the Well co-operating with the rack and retaining it in enga-gement with the gear while the car is in proximity to the door,substantially as described.

4. The combination, with an elevator-car having the movable rack thereon, of a door leading into the well, the plate secured in the well, having the lug at one side, the gear connected to the door and Operating by its rotation to open and close it, and the pivot-pin securing the gear to the plate, substantially as described.

5. In a door-Operating device for elevatorwells, the combination, with the door and operating device therefor located in the well,ol` a car and a device on the car co-operating with the one in the Well for aetuating the door, capable of being moved out of co-operative position, and a stationary projection or retaining device engaging the device on the car and maintaining the two devices in connection when once engaged until the door has been opened and closed, substantially as described.
