To all whom it may concer-n:

Be it'known that I, BYRON C. RIBLET, a citizen of the United States of America, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Tramway Bucket and Rope Clips and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iguresof reference marked thereon, which form a part of this specification.

My invention relates to improvements in clips for attaching a bucket to the tractionrope of aerial wire-rope tramways; and the objects of my invention are, irst, to provide a clip provided with a universal joint that permits of universal movement of the bucket relative to the traction-rope in all directions; second, to provide a clip having a ball-andsocket-joint connection between the tractionrope and the bucket that is easily and quickly disconnected. I attain these objects by the mechanism illustrated inthe accompanying drawings, in which-'- Figure 1 is a perspective view of a fragment of an aerial wire-rope tramway, showing a trolley-bucket mounted on the stationary or track rope and connected to the traction-rope by my improved universal-joint clip. Fig. 2 is a plan view of my improved clip. Fig. 3 is an end elevation of my improved clip. Fig. 4 is a side elevation of the socket part of the balland-socket joint of my improved clip. Fig. 5 is a side elevation of the ball part of my improved clip. Fig. 6 represents aside elevation of one-half of the socket part of my improved clip. Fig. 7 is a plan view of a modiiication of the socket part of my improved clip, and Fig. 8 is a section of Fig. 7 on line 8 8.

Similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates the track or stationary rope g 2, the traction-rope, and 3 the trolley of the bucket; 4, the pendants of the bucket; 5, the bucket of a tramway, and 6 a cross-bar that extends across and is secured to the pendants ofthe bucket. While a tramway-bucket contains the above parts, the term bucket as hereinafter used in a general sense implies a complete bucket. To the cross-bar 6 I secure by bolts 7 and the rivets 7 A lates 8 and 9, which form the base of a brac et that forms one part of the clip and which. I call the socket member of the clip. From the base members 8 and 9 a stem 10 projects at right angles, at the end of which a hollow ballshaped spherical socket 11 is formed. This hollow ball forms the socket of the universal joint of my clip. The interior of this spherical socket is preferably made round and spherical. This socket and its stem and the base is made in two equal halves 12 and 13, that are separated through the center of the ballsocket. The two halves ofthe base are preferably made with projecting lips 14, which extend around and fit against the edges of the cross-bar and with the bolts hold the two halves of the base in alinement. The two halves of the socket are bolted together by a bolt 15, that passes through both halves of the stem. A recess 16 is formed in the terminal end of the shell of thesocket to form a passage for the stem 17 of the ball 18, which is formed on the body portion of the ball part of the clip. The body of the ball portion of the clip comprises a narrow rectangular plate 19, one side edge of which is provided with a curved groove 20, in which the traction-rope rests. At the opposite side edge of theplate 19 from the grooved edge right-angled integral marginal lugs 21 and 22 are formed that project from the rear side edge and from adjacent to the opposite ends of the plate. Through these marginal lugs apertures 23 are formed adjacent to the opposite ends of the plate, in which are placed the ends of yoke or V bolts 24, the ends of which are threaded and are rovided with nuts 26, that screw against t e rear side of the lugs. The curved portions of these V-bolts are iiattened out in the form of a thin band or ribbon 25, that surrounds the rope and the plate, and when the nuts 26 are tightened clamp the rope in the groove and to the plate or body portion of the clip. From the center of plate 19 the stem 17 projects and terminates in a ball 18, which fits snugly, but pivotally, in the hollow shell of the spherical socket. The ball is inserted in the spherical socket by separating its halves, which is done by removing the bolts 15 and 7 and the half 12. tween the halves and the half 12 again bolted to the cross-bar and then to the other half by replacing and tightening the bolts 7 and 15. The recess in the socket permits the bucket and cross-bar and the socket to swing vertically through an arc of a circle of about fortyiive degrees above and below the horizontal The ball is then inserted be- IOO center oi the clip. The bucket and socketv are also free to swing vertically in a plane horizontal to the axes of the traction and stationary ropes, as the socket can turn freely on the ball in any direction. The bucket is tohus enabled to swing in any direction on the all.

In Figs. 7 and 8 I illustrate a modification of the construction of the socket and of the clip. In this modification the base-plate and the stem of the socket are made in one integral piece, and the base is secured at both ends to the cross-bar, preferably by rivets. As constructing the base and stem and socket in one integral casting make it necessary that some other method be employed to introduce the ball into the socket than that shown in Figs. 2, 3, and 4, I preferably construct the socket in the following manner: I form a laterally-extending hollow casing 28 on one side of. the socket and make the aperture in it large enough t-o permit the ball to be inserted through it into x the socket. I preferably make this aperture round, and the terminal end ol the casing, as well as the socket, contains an aperture for the ball to pass through. In the round aperture of the casing I fit a plug 29, the inner end of which is concaved to iit snugly the surface of the ball. I secure this block in position by a split pin 30, which I extend down through the casing and block. To remove or insert the ball in the socket, it is only necessary to remove the split pin and the block, when the ball can be moved laterally in and out of the socket.

My invention is simple, durable, inexpensive, and easily and quickly applied to the buckets and the traction rope or tramways.
