## Abstract

The invention concerns an arrangement in the supply of rope to the speed limiter of an elevator. The arrangement comprises at least a braking device for braking the rope being supplied to the speed limiter. As new rope is being fed to the speed limiter, the new rope has been fitted to run via the braking device and under a diverting pulley in the lower part of the elevator shaft and passed further from the diverting pulley over an upper speed limiter pulley to act on the safety gear of the elevator.

## Claims

### Claim 1

Arrangement in the supply of rope to the speed limiter of an elevator, said elevator comprising at least a hoisting machine and an elevator car suspended to be supported by the hoisting machine and fitted to move along guide rails in an elevator shaft, and said speed limiter comprising at least an upper rope pulley placed essentially in conjunction with the speed limiter, over which pulley the speed limiter rope has been fitted to run, and a diverting pulley which is placed essentially in the lower part of the shaft and under which the speed limiter rope has been fitted to run, and a safety gear, to which the rope is secured, wherein the arrangement comprises at least a braking device for braking the rope supplied to the speed limiter, said braking device being fitted to maintain a sufficient tension of at least that portion of the rope which runs over the rope pulley to permit gripping during the supply of new rope.

### Claim 2 (depends on 1)

Arrangement according to claim 1, wherein that, as new rope is being supplied to the speed limiter, the new rope has been fitted to run via the braking device and under the diverting pulley in the lower part of the elevator shaft and further from the diverting pulley over the upper speed limiter pulley to act on the safety gear of the elevator.

### Claim 3 (depends on 1)

Arrangement according to claim 1, wherein the arrangement comprises a rope feed device, on which the braking device is disposed and which rope feed device has been fitted to be movable with the elevator car.

### Claim 4 (depends on 1)

Arrangement according to claim 1, wherein the braking device has tensioning elements provided with adjustment of compressive force and arranged to maintain a desired tension of the new rope passing through the braking device.

### Claim 5 (depends on 1)

Arrangement according to claim 1, wherein the braking device has locking elements for locking the new rope so as to keep it immovable relative to the braking device during normal operation of the elevator.

### Claim 6 (depends on 1)

Arrangement according to claim 1, wherein the rope feed device comprises a lever arm hinged to be movable in a vertical plane, to the free end of which are fastened both the first end of the rope coming from the upper rope pulley of the speed limiter and the rope going from the rope feed device to the safety gear.

### Claim 7 (depends on 1)

Arrangement according to claim 1, wherein the braking device has at least two mutually parallel braking plates (34, 35) having vertical grooves in the middle of their side surfaces, said grooves being fitted opposite to each other in the braking device, and the new rope has been fitted to run in the space formed by the grooves through the braking device.

### Claim 8 (depends on 1)

Arrangement according to claim 1, wherein the braking plates are provided with grooves of mutually different sizes so that each braking plate has one groove on either side and that the two grooves on the same braking plate are of mutually different sizes.

### Claim 9 (depends on 1)

Arrangement according to claim 1, wherein it has been adapted to supply new rope to the speed limiter by moving the elevator car upwards.

### Claim 10 (depends on 1)

Arrangement according to claim 1, wherein it has been adapted to supply new rope during a jump-lift from a reel placed on the elevator car so that the new rope going through the rope feed device is passed through the braking device, in which braking device the tension of the rope is adjusted to be such that the friction on the upper rope pulley of the speed limiter is sufficient to activate the safety gear if necessary even during a jump-lift.

### Claim 11 (depends on 2)

Arrangement according to claim 2, wherein the arrangement comprises a rope feed device, on which the braking device is disposed and which rope feed device has been fitted to be movable with the elevator car.

### Claim 12 (depends on 2)

Arrangement according to claim 2, wherein the braking device has tensioning elements provided with adjustment of compressive force and arranged to maintain a desired tension of the new rope passing through the braking device.

### Claim 13 (depends on 3)

Arrangement according to claim 3, wherein the braking device has tensioning elements provided with adjustment of compressive force and arranged to maintain a desired tension of the new rope passing through the braking device.

### Claim 14 (depends on 2)

Arrangement according to claim 2, wherein the braking device has locking elements for locking the new rope so as to keep it immovable relative to the braking device during normal operation of the elevator.

### Claim 15 (depends on 3)

Arrangement according to claim 3, wherein the braking device has locking elements for locking the new rope so as to keep it immovable relative to the braking device during normal operation of the elevator.

### Claim 16 (depends on 4)

Arrangement according to claim 4, wherein the braking device has locking elements for locking the new rope so as to keep it immovable relative to the braking device during normal operation of the elevator.

### Claim 17 (depends on 2)

Arrangement according to claim 2, wherein the rope feed device comprises a lever arm hinged to be movable in a vertical plane, to the free end of which are fastened both the first end of the rope coming from the upper rope pulley of the speed limiter and the rope going from the rope feed device to the safety gear.

### Claim 18 (depends on 3)

Arrangement according to claim 3, wherein the rope feed device comprises a lever arm hinged to be movable in a vertical plane, to the free end of which are fastened both the first end of the rope coming from the upper rope pulley of the speed limiter and the rope going from the rope feed device to the safety gear.

### Claim 19 (depends on 4)

Arrangement according to claim 4, wherein the rope feed device comprises a lever arm hinged to be movable in a vertical plane, to the free end of which are fastened both the first end of the rope coming from the upper rope pulley of the speed limiter and the rope going from the rope feed device to the safety gear.

### Claim 20 (depends on 5)

Arrangement according to claim 5, wherein the rope feed device comprises a lever arm hinged to be movable in a vertical plane, to the free end of which are fastened both the first end of the rope coming from the upper rope pulley of the speed limiter and the rope going from the rope feed device to the safety gear.
