CLUTCH FOR AERIAL ROPEWAYS.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed December 13, 1905. Serial No. 291,569.

To wZZ whom, it may concern:

Be it known that I, GiULIo CERETTI, a subject of the King of Italy, residing at Milan, Italy, have invented certain new and useful Improvements in Clutches for Aerial Ropeways, of which the following is a full, clear, and exact specification.

My invention relates to improvements in aerial ropeways; and the same has for-its ob 'ect more particularly to provide a simple, efficient, and reliable device whereby the carriers or load to be conveyed may be automatically coupled to or uncoupled from a traveling hauling rope or cable.

Further, said invention has for its objectto provide a coupling for carriers traveling u pon a fixed rail or rope and conveyed by means of a traveling rope or cable, which may be arranged tooperate in a plane either above or below said rail or rope.

To the attainment of the aforesaid objects and ends my invention consists the novel details of construction and-in the combina tion, connection, and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like numerals of reference indicatelike parts, Figure 1 is a side viewof an apparatus constructed according to and embodying my said invention, the same being shown in combination with a fixed rail and disengaged from a superposed hauling-cable. Fig. 2 is a top or plan view of the same, showing the same in engagement With said cable. Fig. 3 is a section taken on the line 3' 3 of Fig. 1, and Fig. 4 is an enlarged detail perspective view showing the construction of the movable jaw member of the clutch and the means for actuating the same. I

In said drawings, designates the carriertruck, comprising the side members 1 1 united by transverse webs 12 12, forming guides. At the opposite ends of the truck 10, intermediate the side members 11 11, are mounted grooved wheels 13 13, adapted to ride upon the rail 14 in the ordinary manner.

At the upper edge of one of the side members 11 are provided an integral upwardlyrojecting jaw 15 and forwardlyprojecting ugs 15* 15 in which is pivotally secured a movable jaw 16, having a depending arm 1.7. 18 denotes a sliding link which is mounted to reciprocate transversely the carriertruck 10 and has its: opposite ends extending through the side members 11 11. The forward-projecting end of said link 18 is provided with a recess 20, adapted to receive the lower end of the depending arm 17 of the movable jaw 16, and the rear end of said link is bifurcated and adapted to embrace the upwardly-projecting portion 21 of a block 22, which is adapted for vertical movement in the guides or webs 12 12, intermediate the side members 11 11 of the carrier-truck.

The upper portion 21 of the block 22, located between the bifurcated end of the link 18, is provided with an inclined cam groove or slot 23, which cooperates with a roller 24, mounted upon a pin 25, secured transversely 'in the bifurcated portion of the link 18 and.

extending through the inclined slot 23 of the block 21.

The block 22 is further provided with a longitudinal aperture 26, in which is disposed a shaft 27, the ends of which extend through vertical slots 28 in the side members 11 11, and 29 29 denote bearings or frames secured to the projecting ends of said shaft 27, which bearings or frames have their opposite ends bifurcated and provided with rollers 30 30 adapted to ride upon inclined or curved railsections 31 31, arranged and conveniently secured in position at opposite sides of the rail 14 at the point or points where the jaws 15 16 are designed tobe released of their engagement with the operating-cable 32 inorder to stop the travel of the carriers or the load conveyed.

Upon one end of the shaft 27 ,intermediate the side member 11 and the frame 29, is mounted a bearing 33, which is adapted for attachment to the upper end of a yoke or arm 34, carrying a bucket or other device at itslower end to receive the load to be conveyed.

The operation of the apparatus is as follows: When the parts are in the position illustrated at Fig. 1, the movable jaw 16 will be released and permit the cable 32 to ass freely intermediate the same and the xed jaw 15. As soon as the bucket (not shown) attached to the lower end of the arm 34 has been filled or discharged, as the case may be, the same is shifted so as to cause the rollers 30 30 to leave the inclined orcurved rail-sections 31 31, and thus permit the weight of the bucket (whether filled or empty) to draw downward the block 22 in the carrier-truck '10, and insodoing the forward end of the link 18 and the lower end of the arm 17 of the movable jaw 16 will be Ioi the carrier-truck and is forced outward and the upper end of said movable aw forced toward the fixed jaw 16 and firmly grip the traveling cable 32 and cause the carrier-truck l0 and its attached parts to move therewith.

When the apparatus arrives at the receiving or discharging station, the rollers 30 30 Will ride up upon a similar set of inclined or curved rail-sections, as above described, and in so doing reverse the operation just described and release the movable jaw 16 of its engagement with the cable 32 and cause parts to stop until the same are again placed into operation.

Having thus described my said invention, what I claim, and desire to secure byLetters Patent, is
