RQPEWAY.

SPECIFICATION forming part of Letters Patent No. 626,783, dated June 13, 1899.

Application filed November 7,1898. $erial No. 695,722. (No model.)

To aZZ whom it may concern:

Be it known that I, W'ILLIAM DUSEDAU, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Ropeways, of

which the following is a specification.

My present invention pertains to improvements in aerial ropeways, and resides principally in a ,novel way or manner of supporting the ropes.

In previous structures, so far as Iam aware, the carrying or stationary rope or cable has rested on saddles or support-s firmly fastened to the ropeway-towers, while the traction or moving rope or cable has been carried by rollers or sheaves which were placed on the towers below the bucket of the traveling cars. \Vith my present invention I do away with the fixed support for the carrying-rope and substitute therefor a saddle or support which is so mounted that it can rock or swivel in its bearings. I furth ercarr y or support the traction rope or cable by a sheave that holds said rope near to the carrying-rope and above the traveling buckets.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my improved supporting device; Fig. 2, an end elevation, portions of the device being shown in section; Fig. 3, a top plan view of the saddle; Fig. i, a similar view of the supporting-bracket, the saddle being removed; and Fig. 5, a view showing a slightly-modified form of attaching the saddle.

Referring to the drawings, A denotes a bracket designed to be attached to the ropeway-tower, each tower in the ropeway being provided with two of the devices, one on each side. The brackets are preferably of the form shown, though of course they may be changed in design to meet the circumstances and re quirements of any particular case.

Upon the upper face of the bracket is mounted a saddle B, said saddle in the form shown in Figs. 1 and 2 being provided with laterally-extending lugs or studaxles O,which rest in suitable rounded bearings formed in the upstanding arms D. It will thus be seen that the saddle is free to rock upon its axis and to accommodate itself to the varying inclination of angle of the carrying-rope E, which rests thereon. The upper face of the saddle is rounded out (seeFig. 2) and is also curved lengthwise, as indicated in Fig. 1, so that the rope does not bear throughout the entire length of the saddle. The cross-curvatu re forms a good seat for thea'ope or cable, while the longitudinal curvature permits the saddle to rock as the inclination of the rope varies under the load.

In the lower end of the bracket there is secured an axle F, upon which is mounted a sheave-wheel G, the traction-rope H passing over said sheave, as indicated. It is preferable that the sheave should be provided with some means of lubrication, and in the 0011- struction illustrated the axle is shown as formed with ways or channels I, which are in communication with a pipe or reservoir J, secured to one side of the bracket. Channels I open out into similar openings K, formed in an antifriction-bushing L,which is interposed between the sheave and the axle F. It is manifest that any desired form of hearing may be employed.

In Fig. 5 I have shown a construction wherein the saddle is formed with two depending arms M, which embrace a lug N, which extends up from the bracket, a through-pin 0 being employed for holding the parts together and allowing the saddle to rock or tilt, as required. Other forms of attachment of the saddle to the bracket will readily suggest themselves.

The advantages of the construction above set forth are manifold. The saddle will always take the inclination of the carrying-rope and will thus prevent the rope from injury by not being properly placed in the groove of the saddle. The traction-rope is always carried by the supporting-sheave, and any downward pressure or strain is likewise taken up by the carrying-sheave. The rope will be lifted from the sheave only as much as is necessary to permit the grip of the traction-rope to pass freely. IVith most all of the previous .constructions in this line the car lifted the traction-rope from its roller beneath the car and carried it for quite a distance, thereby putting just that much more weight upon the carrying rope or cable. Any downward strain caused by the tension of the traction-rope, as

tirely avoided. The carrying rope is subjected only to th e weight of the cars, the weight of the traction rope or cable and the downward pressure thereof being carried by the; supporting-sheaves, consequently relieving the carrying-rope from this work.

By the use of a sufficient number of sad-;

dles and sheaves large vertical angles in a line can be easilyovercome without difficulty.

Having thus described my invention, what I claim is 1. In a ropeway, the combination of a bracket or support; a saddle pivotallymounted thereon; and a sheave also carried by the bracket below said saddle, substantially as and for the purpose described.

'2. In a ropeway, the combination ofa suitable support; a saddle having a relatively long continuous bearing-face formed thereon, said saddle being free to rock or tilt longitudinally but held against endwise movement; and a carrying rope or cable resting directly on the upper face of the saddle.

In a ropeway, the combination of a suitable bracket or support; a rocking saddle mounted thereon and held against endwisc movement; a carrying-rope resting in said" saddle; a sheave also carried by the bracket or support at a point slightly below the sad-- dle; and a traction-rope resting upon said sheave.

4. In a ropeway, the combination of a carrying-rope; a traction-rope; a rocking support for the carrying-rope said support being held against e'ndwise movement; and a support for the traction-rope located below the rocking support and in close proximity thereto.

5. In a ropeway, the combination of a carrying-rope; a support for said rope pivotally mounted and held against endwise movement, the upper face of the support being curved substantially as described; a traction-rope; and a sheave for supporting said tractionrope, the sheave being located in close proximity to the rocking support, substantially as described.

6. In combination with bracket A provided with bearings upon its upper face; a saddle mounted on said bearings and free to rock or tilt longitudinally, said saddle being formed with a curved seat and held against endwise movement, substantially as described; and a sheave carried by the bracket below said saddle.

7. In a ropeway, the combination of a suit.- able support; a saddle having a long contin uous conveXly-curved bearing-face formed thereon, said saddle being free to rock or tilt longitudinally but held against endwise movement; and a carrying rope or cable resting directly on the upper face of the saddle.

In witness whereof I hereunto set my hand in the presence of two witnesses.

WILLIAM DUSEDAU.
