SUSPENSl'ON-CABLEWAY AND ROPE CARRIER.

SPECIFICATION forming part of Letters Patent No. 631,601, dated August 22, 1899. Application filed March 11, 1899. vSerial No. 708,683.. (No model.)

T0 all whom it may concern:

Be it known that I, GUsTAF PERSON WERN, of the city of New York, borough of Manhattan, in the county and State of New York,have invented a new and Improved Suspension-Cableway and Rope Carrier, of which the following is a full, clear, and exact description.

The invention relates to aerial hoisting and transporting devices; and its object is to provide a new and improved suspension-cableway and rope carrier arranged to properly support a carriage or traversing rope and a hoisting-rope between the carriage and the towers, to avoid slack in said ropes, and thereby insure a proper propulsion of the carriage along the suspension-cableway and a ready raising and lowering of a load.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the'claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement as applied. Fig. 2 is an enlarged plan view of the improvement at one of the towers. Fig. 3 is a plan view of the carriage and the ropes connected therewith; and Fig. 4 is a transverse section vof the hanger-rope and clamp for moving the hanger to position, the section being taken on the line 4 4 in Fig. 2.

A standing cable A is stretched between suitable towers B B or other structures or elevated points, and on said cable are mounted the pulleys C of a traveling carriage C, connected with a traversing or carriage rope D, extending over pulleys E E2 on the tower B and a pulley E on the tower B and passing from the pulleys E E2 to a suitable drum under the control of the operator to impart a traveling motion to said traversing rope and move the carriage C forward or backward on the suspended cable A.

In the carriage C are journaled the usual' sheaves F for hoistinga fall-rope G, carrying a fall-block H for supporting a load, said hoisting-rope G passing over a pulley G in the tower B and then passing to the usual hoisting-machine under the control of the operator for raising and lowering thefall-block H and the load carried thereby.l

On the carriage C and preferably near the upper end thereof is secured one end of a hanger or carrier rope I, extending over a pulley I', journaled in the top of the tower B, to then wind on a drum I2, likewise j ournaled in said tower and provided with a rope I2, carrying a Weight I4 for turning said drum I2 and winding up the hanger-rope I during the return movement Of the carriage, as hereinafter more fully described. The hanger-rope I serves to carry the hangers J J J2 J 2 successively forward for properly supporting the carriage-rope D and the fall or hoisting rope Gr and for supporting the same at intervals, so that none of the ropes are slack. When the carriage C is near the tower B, then the several hangers J J J2 J 2 are assembled near the said tower, and when the carriage C moves outward in the direction of the arrow a then said hangers Vare successively moved in the same direction and at intervals to support the carriage-rope and the fall or hoisting rope at suitable intervals between the carriage and the tower B. Each hanger J is provided with grooved pulleys K, journaled in the frame L of the hanger and adapted to travel on the Asuspension-cable A in the Inanner hereinafter more fully described.

The rope I is preferably made with two strands spaced apart, as plainly shown in Figs. 2 and 4, and said strands are rconnected with each other at intervals by clamps forming projections O O' O2 O3 of increasing size, as is plainly shown in Fig. l, to engage sets of pulleys N N' on the hangers J J' J2 J2, respectively. The sets of pulleys N N' 011 the several hangers are spaced apartin such a manner that the first clamp O can readily pass between the pulleys N N of the hangers J J2 J 2, but engages the set of pulleys N N' of the first hanger J, so that when the carriage moves outward the clamp O after passing through the pulleys on the hangers J 2 J 2 J strikes the pulleys on the hanger J, and thus moves the hanger along as the carriage proceeds. As

the carriage proceeds, the second clamp O passes through the pulleys of the hangers J 2 J 2 to Iinally engage and abut against the pul- IOO leys of the second hanger J, so that this hanger is moved along as the carriage proceeds farther, but is located a distance from the iirst hanger corresponding to that between the two clamps O O. In the same manner the next hanger J2 is carried along by the clamp O2, and finally the hanger J3 is carried along by the clamp O3, so that the several hangers are extended at intervals between the carriage C and the tower B to properly support the carriage-rope and the hoisting-rope and avoid slack therein. As the carriage C moves outward and pulls along the rope I, the latter unwinds from the drum I2, and the rope I3, having the weight I4, is wound up on said drum. IV hen the carriage C is on the return movement in the inverse direction of the arrow a', then the rope I is automatically wound up on the drum I2, owing to the weighted rope I3 rotating the drum I2 in the inverse direction, said rope Is unwinding from the drum. rlhe several hangers J J/ J2 J3 remain at a standstill until the carriage C finally comes in contact, first, with the hanger J to move the salne along in the inverse direction of the arrow cd, and then the hanger J abuts against the hanger J and moves this hanger along, and so on until the several hangers are gathered up and returned to their previous normal position near the tower B at the time the carriage C has reached its starting-place.

In order to support the hoisting-rope and the carriage-rope in the several hangers, I prefer to provide the same with suitable pulleys I?, as indicated in the drawings.

By having the two strands for the hangerrope I connected with each other by the clamps, as shown, a very strong rope is provided, and consequently a proper pull is exerted on the several hangers to insurea positive forward movement ot' the hangers as the carriage proceeds on its outward journey.

The upper strand of the traversing rope D passes between supporting-pulleys C2, journaled on the frame of the carriage C, as is plainly indicated in Figs. l and From the foregoing it is evident that the device is very simple and durable in construction and the hangers are moved outwardly at the proper time as the carriage proceeds without undue friction or strain on any of the parts of the device.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A device of the class described, provided with a hanger-rope, consisting of two separated strands, and clamps for connecting the strands with each other at intervals, said clamps increasing in size, for the purpose speciiied.

2. A device of the class described, provided with a carriage, a hanger-rope having one end attached to said carriage, a series of clamps secured and spaced on the said hanger-rope, hangers for supporting the hanger-rope, a

hoisting-rope, adapted to be engaged by said clamps, to move the hangers successively along the carriage proceeds on its outward journey, and a weight-driven drum, for automatically windin g up the hanger-rope when the carriage returns, substantially as shown and described.

3. A device of the class described, provided with a carriage, a hanger-rope having one end attached to said carriage, a series of clamps secured and spaced on the said hanger-rope, hangers for supporting the hanger-rope, a hoisting-rope, adapted to be engaged by said hangers, to move the hangers successively along as the carriage proceeds on its outward journey, and a Weight-driven drum, for automatically winding up the hanger-rope when the carriage returns, said carriage then returning said hangers, substantially as shown and described.

1l. The combination, with a cableway, a carriage mounted to travel thereon, a traversing rope for moving said cableway, a hoistingrope connected with said carriage, a hangerrope attached to said carriage and moved ou tward by the same, a drum on which said hanger-rope winds and unwinds, clamps on said hanger-rope, and placed a suitable distance apart and increasing in size from the carriage rearward, and hangers for supporting said traversing rope and said hoistingrope, and mounted to travel on said cableway, each hanger having a pair of pulleys for engagement by a corresponding clamp on the hanger-rope, substantially as shown and described.

5. In a cableway, the combination with a standing cable, a carriage,and means for hauling the Same, of a hanger-rope, one end of which is attached to the carriage, the hangerrope moving with the carriage, means having connection with the other end of the hangerrope for automatically maintaining the tension of the hanger-rope as the carriage moves toward or from said means, and hangers mounted on the standing cable and serving to be moved by the hanger-rope along said cable in unison with the movements of the carriage.

6. In a cableway, the combination with a standing cable, a carriage mounted to move thereon, means for hauling the carriage, of a hanger-rope, a drum around which the other end of the hanger-rope is wound, means operating with the drum to automatically control the same, whereby to maintain the tension of the hanger-rope as the carriage moves toward and from said drum, and hangers mounted to travel on the standin g cable, the hangers being moved by the hanger-rope in unison with the movements of the carriage.
