ELEVATOR SAFETY Nl ECHANISM.

SPECIFICATION forming part of Letters Patent No. 601,536, dated March 29, 1898.

Application filed October 5, 1897. Serial No. 654,124. (No model.)

` T @ZZ whom it may concern:

- Be it known that I, JOHN T- TAYLOR, of New York city, in the county and State of New York, have invented a new and Improved Elevator Safety Mechanism, of which the following is a full, clear, and exact description.

V as to stop the car, the clutches being actuated by automatic devices on the car.

The object of this invention is similar to that disclosed in my pending application, Serial No. 622,661, filed February 9, 1897-that is to say, to provide means whereby the conductor of the car may throw the clutch intol operation should the automatic devices act too slowly or fail entirely.

This specification is the disclosure of one form of my invention, While the claims dene the actual scope of` the invention.

Reference is to be had to the accompanying drawing, forming a part of this specification, which is a fragmentary sectional view of my invention.

The elevator-car 1 moves in the Well between the guideways 2 and has clutch-bars 3 sliding transversely to engage with the guides, so as to arrest the movement of theelevator. At the top of the well on a support 4 is mounted a pedestal 5, carrying a bull-wheel 6, geared with the centrifugal governor 7. The centrifugal governor 7 actuates two clampingsegments 10 through the medium of a lever 8 and a link 9.` Running over the bull-Wheel 6 is a rope 11, which has yielding connection with suitablelink mechanism 12, through the medium of which mechanism the clutch-bars 3 are moved in and out to engage and disengage the guides 2. This link mechanism, as shown, consists of a lever 20, fulcrumed upon the car and engaged by a spring 21, secured to the rope 11, a rod 22, pivotally connected to said lever and mounted to slide vertically in a guide 23 .upon the car,levers 24, fulcrumed upon the car at 24 and connected at their adjacent ends to the rod 22, and togglelevers 25, pivotally connected at their opposite ends to the car and tothe clutch-bars, respectively, while the jointed ends of the togto operate so as to project outwardly the bars 3 and stop the movement of the car.

My present invention is an electromechanical apparatus to cause the operation of the clamping-segments 10 from means within the car, and consequently under the immediate control of the conductor thereof. An electromagnet 13 is situated on the support 4 and has its armature 14 connected by a bar 15 with a lever 16, which is in connection with the link 9 and with the clamping-segments 10. The magnet 13 may be properly energized by suitable means-such, for example, as primary batteries 17. An insulating-tube 18 runs from a point adjacent to the batteries 17 and magnet 13 to the car 1. The tube 18 carries the conductors of the electromagnetic circuit, and by operating the push-button 19, to which the wires are connected, such circuit may be closed. Upon the closure of this circuit the armature 14 is attracted to the magnet 13 and the clamping-segments 10 are caused to hold the rope 11 and effectthe operation of the clutch-bars 3. It is thus that I place the clutch-barsimmediately under the control of the operator of the car.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the elevator-car, normally inactive arresting mechanism thereon, a rope connected to said mechanism and held to normally travel with the car, an engaging device for holding said rope stationary, an electrically-actuated mechanism for operating said engaging device, conductors extending from the car to said electrical mechanism, and a circuit-closer located upon the car and connected with said conductors.

2. The combination ofthe elevator-car, nor- IOO mally inactive arresting mechanism thereelectromagnet to the car, and a circuit-closer on, a rope connected to said mechanism and located upon the car and connected With said held to normally travel with the ear, a clampconductors. ing device for holding'the rope stationary, an

5 armature operatively connected to the clamp- Witnesses:

ing device, an electromagnet for attracting J. HARRY NICHOLSON, said armature, conductors extending from the LORETTA E. HICKS.
