ELEVATOR.

SPECIFICATION forming part of Letters Patent N o. 579,430, dated March 23, 1897. Application filed November 2'7, 1896. Serial No. 613,536. (No model.)

To all whom, it may concern.'

Beit known that we, EDWARD L. HAIL and GEORGE HAIL, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Elevators, of which the following is a specification.

This invention has relation to elevators of the class known as passenger-elevators, which are employed for carrying persons between the iioors of a building. There are many dangers incident to taking passengers on and letting them off from an elevator-car, resulting from the possibility of the car starting before the door of the corridor is closed, and hence one of the objects of our invention is to prevent dangers of this kind by connecting the door of the corridor in such way with the motor-controlling device as to lock the same from action during the time that the corridor-door is open and until it is closed.

To these ends, therefore, the invention consists of an elevator having a driving mechanism for elevating and lowering the car, a device for controlling the movements of the driving mechanism and operated by aline, an opening device for the door of the corridor, a lock for locking the motor-controlling device, and connections between the dooropening device and the lock whereby when the door is opened by the said device the lock is moved into engagement with the motorcontrolling device to hold the latter from movement. 4

The invention likewise consists of other features of improvement, which we will hereinafter describe with particnlarity, and set forth in detail in the claims hereto appended.

Reference is to be had to the accompanying drawings, and to the letters marked thereon, forming a part of this speciiication, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure l is a more or less conventional view showing one form in which our invention may be embodied, there being illustrated in said figure a corridor-door, a motor-controlling device, a lock for the motor, a device for opening said corridor-door, and connections between said door-opening device and the lock for the motor-controlling which controls the lock for the motor-con- 6o trolling device, one door being represented as having been opened and the motor-controlling device being shown as locked. Figs.v 8, 9, and l0 illustrate latches for locking the door and which are arranged to be operated when the handle of the lever is grasped. ll shows in perspective the hook end of bell-crank lever.

Referring to the drawings, a indicates a Fig. the

corridor-door which is adapted to slide back 7o and forth to open and close the aperture leading from the corridoi' into the elevator-hatchway.

At l) we have indicated a shaft the movements of which control the movements of the mechanism for raising and lowering the elevator-car and is controlled by a pulley b' on which a controlling-line a: passes, which line may be actuated by the attendant on the car.

The raising' and lowering mechanism may 8o consist of a motor of any nature that it may be desirable to use-such as an electric motor, a hydraulic cylinder, cbcthe motor not being shown, as it forms no part of the present invention. which, as above stated, is affixed a pulley b for the controlling-line, (and between said line and the motor,) we rigidly secure a disk c, which is provided in its periphery with the notch d, and when the disk is in that position 9o which it will assume when the motor is at rest the notch d is in alinement with and is adapted to receive a sliding bolt c, which reciprocates in the guides f f. 'lhe said bolt is connected at its end with a line g, which 95 may be either a rope, a chain, or any other means for accomplishing the purpose to be f described, which line is passed around an idler-pulley h near the bolt and an idlerpulley i at the top of the well or hatchway 10o and has upon its end a weight j. The line extends throughout the length of the hatchdevice. 55

Upon the said shaft b, on

way in position to be engaged by the dooropenin g device orlevers connected therewith, as we will proceed to hereinafter describe.

The weight j is sufficiently heavy to hold the bolt e out of engagement with the notch CZ in the disk c, and in' order to throw the sliding bolt into the notch when desired we employa weighted lever Zt, having an end extending down into an aperture or slot in the bolt. Vhen the bolt is relieved of the weight j, the weighted lever 7s will throw it forward so as to enter the notch CZ in the disk c. For drawing down upon the line g, so as to throw the bolt c into engagement with the motorcontrolling device, we employ means which coact with the corridor-door, as we will now describe.

Z is a lever, fulcrumed at on. on a stationary support n, which is shown as on the wall of the hatchway. The leverpasses between two rollers o o, journalcd on the door a, and is cam-shaped or curved, so that when it is swung upon the pivot m it throws the door open, as will be understood.

The line g is provided with stops, clips, or attachments p, with which may engage the forked end q of a bell-crank lever r, pivoted on the wall of the hatchway in proximity to the line, and the end of the lever lr is connected by a link s with the end of the dooropening lever Z.

The end of the bell-crank lever to which the link s is attached is provided wit-h a camslot r', into which a pin S' on the link s eX- tends. The link slides longitudinally in guides s2 32, and the cam-slot is so arranged that the first movement of the lever Z upward will cause the pin s to thrust the rear end of the bell-crank lever upward and force the forked end downward to operate the lock for the motor-controlling device, the remainder of the movement of the lever Z not affecting the lever r, since the pin s travels in a straight portion of the cam-slot, as shown in Fig. 2. The rollers 0 o on the door are separated far enough to allow the lever Z to be moved sufiiciently to cause the locking of the motoreontrolling device prior to any movement of the door toward open position.

Now it will be seen from Figs. 1 and 2 that when the lever begins to move upward and backward the link s will be drawnl forward, rocking the lever r on its pivot, and thereby causing the forked end thereof to engage the clip or attachment p on the line g, thus forcing down the said line and allowing the weighted lever to throw the bolt e into the notch CZ of the motor-controlling device, and then the continued movement of the lever will cause the moving of the door to open position.

In Fig. 7 we have shown a series of doors (one being opened) each equipped with an opening device for operating on the line connected to the lock for the motor-eontrolling device, and from the said figure it will be seen that if any one of the said doors be opened the motor-controlling device will be locked.

The door-opening lever is provided with a depending portion t, having a knob or handle u on the lower end therecf,which may be grasped by the attendant on the car for throwing the lever upward and backward..

In Figs. 3 to 7, inclusive, we have shown the door opening and closing lever as operating to start the door toward open position immedi at-ely upon its being swung on its pivot, and in this case the entire movement of the lever is utilized in opening the door, although the motor-controlling device is looked before the door is moved to any extent. In all other respects the devices operate precisely the same as above set forth.

In Fig. S the door-latch a2 is pivoted at b2 and has a pointed hooked end to engage a catch on the door-framing. It is provided with a knob c2, being so placed as to be at the side of the handle u, sothat both may be grasped by the attendant at the same time to both unlatch the door and raise the lever to start the said door toward open position, the knob c2 being released as soon as the latch strikes the bridge e2.

In Fig. 9 the end of the depending arm of the lever is bifurcated, as at d2, thereby allowing the knob c2 to be placed below and near to the handle u in a position to be easily grasped.

In Fig. 10 the bifurcated end of the lever is provided with springs f2, which yieldingly engage the knob on the latch, so that in opening the door the operator merely takes hold of the lever-handle u and swings the lever upward, the springs drawing the latch out of engagement with the catch and then releasing it, as the latch is prevented from further upward movement by the bridge c2.

From the foregoing it will be observed that it is not necessary to always employ the mechanism for locking the valve in connection with a door opening and closing lever, as a hand-operated lever may be employed separately and independently of the door forlocking the valve-controlling devices.

fe make no claim herein to the means shown and hereinbefore described for opening the door per sc, this being the subjectmatter of our copending application, Serial No. 596,105, filed June 19, 1896.

It will be understood that we do not intend to limit ourselves to the precise details of construction as herein shown and described, nor to the particular form of motor-controlling line or device employed, since any other of the well-known electrical or mechanical controllers may be used.
