SPECIFICATION forming partrof Letters Patent N o. 745,659, dated ljecember 1, 1903. Application led November 17, 1902. Serial No. 131,893. (llo model.)
To all whom it may concern.-
Beit known that LRUD OLE PEAEEENB'ACH, manager, a subject of the King ofPrussia', Emperor of Germany, residing at 34: Pfaffendorferstrasse, Leipzig, Germany, have invented a new and useful .Improvement in Rope Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.
My invention relates to improvements in rope railways.
The object of my invention is to provide a device of this character which shall he simple in construction and efficient in operation.
A further object of the invention is to provide means by which the carriages ymay be drawn around curves by a simple and efiicient means. Y
A further object of the invention is to provide a structure by whichthe carriages on either track take the curve inthe same way and with equal facility.
A further object of the invention-is to pro- Vide means by which carriages can be drawn around curves without the use of an overhead coupling.
Other objects of the invention will appear more fully hereinafter.
Myinveution consists,substantially, in the construction, combination, location, and arrangement of parts, as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.
Referring to the accompanying and to the various views and reference-signs appearing thereon, Figure l 'is a top plan View showing a portion of a rope railway taken at a curve and embodying the princi- Fig. 2 is a View in transverse vertical section of the same. Fig. 3 is a similar view, on a smaller scale, taken on a straight part of the track and embodying the principles of my invention.
The same part is designated by the same drawings,
by a traction-rope, which is secured thereto either above or below the stationary cable. If the track is straight throughout its length, the tractionrope is generally placed below the stationary cable for the reason that in this position it is better located with relation to the load. In other words, its line of pull is 'more nearly opposite the line of resistance.Y
If, however, the track contains curved portions, it becomes difficult or impossible to so connect thetractiou-rope for the reason that it is liable tor fall on the outside of the de* pending portion of the carriage in rounding the,curve,^whereby its tension is exerted to bind or throw the carriage in a lateral or sidewise direction--that is, toward the center of curvature of the rounded portion of the track, This action does not occur if the tractiomrope falls on the inside of the depending portion of the carriage with relation to the curve, since the lateral tension is then taken up by the usual horizontal guide-wheels, which are provided at the curved portions of the track.
Accordingly by the usual Varrangement of rope'railways one of the tracks is correctly and the other incorrectly disposed for the purpose of carrying the carriages around acurve. This difcuity can be overcome byconnecting the traction-rope to the carriage at a point above the fixed cable; but this is disadvantageous for the reason that it causes an irnproper application of the tractive force.
In accordance with the principles of my invention I provide an arrangement by which the carriages on either track can be led around a curve by the use of a traction-rope and in such a manner that no lateral or binding strain is put upon the carriages of either track.
Referring to the drawings, the characters I and II designate the fixed cables or tracks of a rope railway. Z designates the supporting frame or arm for the cable I, while r designates the corresponding support for the cable II. These maybe disposed upon the usual trestle-frames in any desired manner and in suitable spaced relation. I have shown a convenient method of arranging these supports in Fig. 2, in which both are hung from a horizontal beam; but the supports r instead of being placed symmetrically with regard to M the center line of the railway, as indicated by dotted lines in said figure, are placed in the same relation as the support Z. In other words, both are on the same side of their respective tracks or cables.
f designates the grooved rollers of the carriage, and c indicates the respective hangers from the carriages upon which the usual buckets are hung. At the side of the hangers c are shown gripping-jaws g, arranged to grip and hold the traction-cables h.
1I indicates a series of vertical grooved rollers which support the traction-ropes when the latter is not held up by the grippers. At the straight portions of the track these vertical rollers are alone sufficient to guide the traction-rope; but at the curves additional means are employed in order to resist the lateral strain. b designates rollers which may be employed for this purpose horizontally disposed opposite to the path of movement of the traction-rope on the inside of the curve. rlhese rollers are preferably of comparatively large diameter and spaced around the curve at small angular intervals, as clearly indicated in Fig. l. Accordingly at each curved portion of each track the bearing-rollers b lie on theinside of the curve of the traction-rope, while the hangers c lie on the outside. In this way the hangers are not bound or clamped between the traction-rope and the bearingrollers b fo'r either track.
The construction may be modified in many ways-for example, as shown in Fig'. 3, which is particularly adapted to a straight portion of the track. The supportsl and r are secured upon a diagonal frame-beam, by which means they are disposed in the same relative way as above described.
The operation of my improved railway will be understood from the preceding description. The carriages move upon the xed cables I II, being drawn thereon by the traction-` ropes h. When a curve in the track is reached, the carriages on both tracks pass readily around it, the hangers always falling on the convex side of the traction-rope, whereby they do not interfere with the bearing-rollers b. The road may have two curves or, in fact, any number of curves, provided they all are in the same direction, and the principles of my invention will be equally applicable thereto. It is merely necessary that all of the curves be uniformly either right or left handed.
It is obvious that many different ways may suggest themselves to persons skilled in the art for mounting the respective tracks or cables on their supporting-trestle for enabling the carriages on both tracks of a rope railway to properly round a curve. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but,
Having now set forth the object and nature of my invention and a construction embodying the principles thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is-

3. In a rope railway having a curve, a iixed track following said curve, a carriage thereon having 'a hanger, a gripper on said hanger, and a traction-rope guided around said curve by horizontally-disposed wheels, said hangers falling on the convex side of the curve formed by said traction-rope, as and for the purpose set forth,
