INTERLDCKING MECHANISM FOR A'IORS.
Specification of Letters Patent.
Application filed November 25, 1912 Serial No. $053,958.
To all wbomz't may) concern:
Be it Known that we, JOHN S. MUGKIJ': and THOMAS H. STRALEY, citizens of the United States, residing in Philadelphia,
county of Philadelphia, State of Pennsyl-' Vania, have invented certain Improvements in Interlocking Mechanism for Elevators, of which the following is a specification.
The object of our invention is to simplify the construction of the means for operating the electromechanical or mechanical interlocking means for elevator-st -This type of mechanism prevents the door at a landing from being opened when a car is not at a landing and prevents a car from being oper ated after itcomes to a stand opposite the landing when the door is opened and the mechanism cannot be operated until the door is closed.
In the accompanying drawings:
Figure 1 is a rear view of the operating stand, which is located within the car, the parts being in position at rest when the'car is stationary and at a landing. This view also illustrates the landing door open and the mechanism locked;
Fig. 2 is a view similar to the upper portion of Fig. 1, showing the parts in position when the car is ascending; and
Fig. 3 is a view similar to Fin. 1 with the parts in position when the car is descending.
Ne have illustrated in diagram a part of the landing and the floor of an elevator car showing a type of mechanism at the landing and onthe car such as illustrated in the patent of John S. Muckle, No. 583,331, of 1897, although it will he understood that any of the well known mechanisms of this type may he used without departing from the essential features of the invention.
Referring to the drawings, 1, 1, in. the present instance-are two standards mounted on the floor of a car 24: and these standards carry a frame 2 having a segment 3 with end and central stops, as shown. 4 is a lever pivoted at 5 to the frame 2. On this lever is a toothed segment 6. The teeth or. this ment mesh with teeth of a pinion 7 which is geared to the mechanism fox-controlling the movement of the elevator. 8 is a, shaft mounted in a hearing 9 depending from the one arm of which is connected loya rod 1% to the interlocking mechanism on. the car. The other arm of the lever 13 has a depressed portionglo and is flared at each side of this depressed portion, forming; bearings 16 and '17. the pivot 5 and has a roller 18 which rests in a depressed portion of the lever, when the lever is in the central position, Fig. 1. The interlocking mechanism is that shown and (lQSClilX-Xl in the patent granted to John Muckl, No. 583,331 oi .llday E28, 1897, and consists of a plunger connected hy a rod on to a bell crank lever 27' which is attached to the rod 14-. This plunger has a flange 28 which is engaged by a weighted locking device 29 which is held out of action by a projection on the door 30 at the platform which is at the landing 31. a. roller on the plunger press a spring latch 33 when the plunger is projected so to release the door. ll hen the lever 4- is in. the position illustrated in 1 it is looked as soon the door is opened, asthe inching device 29 is released and engages the'projecting plnngcr 25. ll hen the door is closed, the locking device 29 is -forced to disengage the plunger, after which the lever lcan he turned either to the position shown in Fig. 2 to cause the car to ascend or to that shown in Fig. 3 to cause the car to descend and the lever 13 will he moved to retract the plunger 25, releasing the latch so that it will lock the door 30. in order to stop the car, the lever is moved to the central position, Fig. 1, the plunger projected and as it comes to a stop it will press the latch As soon as the door is opened the lock 29 will he released and will a gain look the lever 4 and the intervening mechanism.
\Ve claim:
1. The combination in an operating device for elevator interlocking; mechanism. of a stand; an operating: lever pivoted to the stand and connected to the means for stoppin g and starting the elevator car, said operatingr lever having an extension; a lever also pivoted to the stand; and a. rod connected to one arm of said lever and extending to the interlocking mechanism of the car, the other arm of the lever having depression for the reception of the extension of the operating lever, the two levers being so arranged in re speet to each other that when the operating ill lever is in the central position the extension is in the depression of the other lever and when the operating lever is moved to either side of the center it will depress the arm of the lever, which is connected to the interlocking mechanism.
2. The combination in an operating device for elevator interlocking mechanism, of a car; a stand mounted thereon; an operating lever pivoted to the stand and arranged to assume either a central position or a position at either side of thecenter, said lever being connected to the means for stopping and starting a car and having an extension beyond its pivot; a roller on the extension; a lever pivoted to the stand; a rod connected to one arm of the lever and to the interlocking mechanism of the elevator, the other arm having a depression and having a bearing on each side of the depression so that when the operating lever is in the central position it is located in the depression and when the operating lever is moved to either side of the center the roller Will'assume a position on either one of the bearings and will depress said arm of the interlocking lever.
In testimony whereof, we have signed our names to this specification, in the presence of two subscribing Witnesses.
