HERMANN lVALTI-IER REINHOLD, OF DUSSELDORF, GERMANY.

SPECIFICATION forming part of Letters Patent No. 767,439, dated August 16, 1904. Application filed May 9, 1904:. Serial No. 207,158. (No model.)

To ctZZ whom it may concern.-

Be it known that I, HERMANN XVALTHER REINHOLD, a subject of the King of Prussia, and a resident of Dusseldorf. Germany, have invented a certain new and Improved Cable- Clip for Suspended Cable-Railways, of which the following is a specification.

This invention relates to an improved cableclip for use with those suspended cable-railways in which the weight of the suspended trolley causes the cable to be gripped,whereas the cable is released when the said weight ceases to act on the clip.

In the improved clip a lever with arms .of unequal lengths is arranged between a vertical slide supporting the weight of the trolley and a horizontally-movable clamping cheek or clip arranged in the running-gear of the trolley, so that the movement of the vertical slide is transmitted to the clip with increased force. This allows of providing the vertical slide with inclined, horizontal, curved, or angular guide-slots, flanges, or the like for operating the double-armed lever. The increased clamping effect due to the lever also allows of using the clip for cable-railways in which the cable is gripped at or about the level of the wheel-axles to prevent the tilting of the trolley. The combination of the clip and lever also allows of gripping the cable at either side of the running-gear, as req uired-that is to say, the trolley need not be turned at the end of the track in order to return along the second cable. The arrangement also allows of negotiating curves of the track without uncoupling the trolley from the cable.

The invention is illustrated in the annexed drawings, in which Figure 1 is a vertical section on the line A B of Fig. 2, showing the simplest form of the clip and running-gear. Fig. 2 is a vertical section on the line C D of Fig. 1, and Fig. 3 a horizontal section on the line E F of Fig. 2. Fig. 4 is a section corresponding to that shown in Fig. 2, but illustrating a modification of the device which allows of gripping the cable at either side of the running-gear. Figs. 5 and 6 are a rear View and plan view, respectively, illustrating the passage of a curve with the clip shown in Fig. 4. Fig. 7 is an elevation illustrating the invention as applied to a cable-railway in which the traction-cable is arranged below the supporting-cable. Fig. 8 is a vertical section on the line G H of Fig. 7.

Between the side plates 1 of the runninggear is arranged the slide 2, to which the suspensory device 4 of the trolley is connected by means of the bolt 3. The slide 2 is vertically guided in the usual manner and is provided with guides 5, the purpose of which is to operate the clip or clamping-cheek 6 by means of the lever 7 when the slide 2 is pulled downward or lifted. The longer arm of the lever 7 is provided for this purpose with a small roller or a pin 8, engaging between said guides 5.

As already mentioned, the use of the lever 7 allows of opening and closing the clip by means of inclined guides or slots of the kind shown in Figs. 2 and 4 or by means of horizontal guides, as shown in Fig. 8. The guides can also be curved or angular. The difference as regards effect is only that if the slide 2 is provided with horizontal guides or grooves it must travel through a longer distance than if provided with curved or inclined guides, but will have only very slight friction to overcome. Angular and curved guides combine the two advantages of short stroke and slight friction and also have the advantage that the opening operation of the clip is first rapid and then more gradual, so that the wear and tear of the clip and the traction-cable is less than with inclined and horizontal guides.

The shorter arm of the lever 7 engages into a suitable aperture in the horizontal part 6 of the clip 6, as shown in Fig. 2. The said part 6 is rectilinearly movable in the bearings 9 and 10, which are integral with the side plates 1 at or about the level of the wheelaxles 11.

The bearing 10 is enlarged to receive the pivot 12 of the lever 7, and the slide 2 is provided with a vertical slot for the horizontal part 6 of the clip.

When the weight of the trolley pulls down the slide 2, the traction-cable 13 is pressed by the clip 6 against the outer surface of the bearing 9, the movement of the said slide being transmitted with increased force to the 1 clip for causing the latter to grip the tractionclip by means of the guides 5 and lever i.

In the form of construction shown in Fig. 1 a fixed clip 15 is provided which is integral with the bearing or frame part for the purpose of coupling the trolley with the tractioncable when traveling on curves or during the return journey, the cable being gripped by the end of the part 6 and the clip 15, as shown in Figs. and (3. During the journey in one direction, Figs. 5 and 6, lefthand side, the clip 6 grips the cable 13, passing round the pulley 16, and during the return journey, Figs. 5 and 6, right-hand side, the clip grips the cable.

For cable-railways in which the tractioncable 13 is arranged below the supporting-cable .18 the form of the device shown in Figs. 7 and 8 is used. In this form of construction one side plate 1 of the vframe projects down ward to a considerable extent and is provided at its lower end with the gripper mechanism. In this case the supporting-bolt Z) is not directly connected to the slide L, but to a slide 2, which is connected to the slide 2 by means of the rod 19. It is obvious that this form of construction can be executed exactly like that of Fig. 41 and that this gripper mechanism can be combined with that of Figs. 2 and ar -that is to say, the slide 2 and the parts 1 can be constructed exactly as shown in Figs. 1 to 4, the slide 2 being, however, also connected to a slide 2 above same in the manner shown in Figs. 7 and 8 or a similar manner, the slide 2 being provided with the supporting-bolt. A combination of this kind can be used for c; ble-railways with traction-cables above or below the supporting-cable and for tracks in which the traction-cable is partly below and partly above the supporting-cable.

I declare that what I claim is- 1. In a suspension cable-railway the combination with a supporting-cable, a traction-cable and a suspended trolley, of a slide adapted to be operated by the weight of the latter, a horizontally movable clip traversing said slide and means intermediate the slide and cable with increased force on movement of said slide in one direction substantially as described.

2. In a suspension cable-railway the combination with a supporting-cable, a traction-eable and a suspended trolley 01 a verticallyguided slide carried by the latter and adapted to be operated by the weight thereof, a horizontally-movable clip traversing said slide and meansintermediate the slide and clip for causing the latter to grip the traction-cable with increased force adjacent the plane of the trolley-wheel axles on downward movement of said slide, substantially as described.

3. In a suspension cable-railway the combination with a supporting-cable, a traction-cable and a suspended trolley, of a verticallyguided slide adapted to be operated by the weight of the said trolley and provided with a guideway, a horizontal]y-movable clip traversing said slide and a lever having arms engaging said guideway and clip respectively and adapted to cause the latter to grip the traction-cable with increased force on downward movement of said. slide, substantially as described.

4. In a suspension cable-railway the combination with a supporting-cable, a traction-cable, and a suspended trolley, of a verticallyguided slide adapted to be operated by the weight of said trolley, a horizontally-movable clip traversing said slide, means intermediate the slide and clip for causing the latter to grip at one end the traction-cable with increased force on downward movement of said slide and a second clip integral with the trolley and between which and the other end of the movable clip the traction-cable is also adapted to be gripped substantially as described.

In witness whereof I have signed this specification in the presence of two witnesses.
