MEANS FOR ATTAGHING ROPES OR CABLES TO WINDING DRUMS.

Application filed December 30, 1921. Serial No. 525,929.

To all whom it may concern:

Be it known that I, ARTHUR GORDON FRENCH, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Linotype and Machinery l Vorks, Altrincham, in the county of Chester, England, have invented new and useful Improvements in Means for Attaching Ropes or Cables to Winding Drums, of which the following is a specification.

This invent-ion relates to improved means same rate, but it sometimes happens that through expansion and contraction of the cable, the level of the delivery board is dis turbed, which level, with the winding mechanism in ordinary use, can only with ditliculty be re-established.

According to the present invention this difliculty is eliminated by so attaching the cable to the winding drum as to enable it to be readily adjusted circumferentially thereon. v

This invention will now be described with reference to the accompanying drawings in which Figure 1 is a side elevation, partly broken away, of the improved winding drum, showing the cable attached to the drum and also broken away;

Figure 2 is a plan of Figure l, and

Figure 3 is a vertical section on the line 3-3 of Figure 1.

In carrying out the invention, the winding drum 1 is provided with the usual flanges 2 to prevent the cable 3 from slipping over the ends thereof, and with two peripheral openings 4, 5 (shown best in Figure 2), one of which, say 4, enables the cable 3 to be passed inwards from the winding surface of the drum to a groove 6 formed in one side face of such drum. This groove 6 extends around the said side face to a position at which it reaches a passage 7 extending transversely through the drum and connecting with a similar groove 8 in the opposite side face, which latter groove connects with the peripheral opening 5, through which the cable again passes out on to the winding surface'of the drum, the cable within the passage forming what may be regarded as a bight.

The

grooves

6, 8, in thetwo side faces are of relatively different depths, the groove 8 being less and the groove 6 greater than the diameter of the cable 3, which latter is retained in the grooves by

annular rings

9, 10 secured to the respective sides of the drum by screws 11 and bolts 12 respectively. By reason of the difference in the depths of the

grooves

6 and 8, the ring 9 attached to the side having the deeper groove 6 does not press on the cable 3, whereas the ring 10 attached to the side having the shallower groove 8 presses on the cable and securely clamps it to the Winding drum.

With a drum constructed as before described, the cable can be readily adjusted for levelling the pile delivery board by slacken ing the ring 10 so as to release the cable 3,

which can then be pulled around the drum in either direction, and after the level has thus been restored or adjusted, this ring 10 is tightened to again clamp the cable to the drum.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is i 1. The combination with a winding drum and a single cable adapted intermediate its ends to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving access to the cable from said periphery to the grooves, two rings adapted to partially enclose the grooves, and means securing one ring positively to each said side face one for tightly clamping and the other for loosely retaining parts of the cable intermediate its ends in the respective groove.

2. The combination with a winding drum and a single cable adapted intermediate its ends to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving access to the cable from said periphery to the grooves, two rings adapted to partially enclose the grooves, one adapted to bear on the cable and the other adapted to bear on the drum,

and means securing the rings to the respec tive side faces, one in contact with a part of the cable intermediate its ends for clamping it tightly within the respective groove and the other out of contact therewith for retaining the cable loosely within the pertinent groove.

3. The combination with a winding drum and a single cable adapted intermediate its ends to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving access to the cable from said periphery to the grooves, two rings adapted to partially enclose the grooves, one adapted to bear on a part of the cable intermediate its ends and the other adapted to bear on the drum, means securing the rings to the resoective side faces, one in contact with the cable for clamping it tightly within the respective groove, and the other out of contact therewith for retaining the cable loosely within the pertinent groove, and a passage for the cable extending transversely through the drum for mutually connecting together the two grooves' 4. The combination with a winding drum and a cable adapted to be coiled around it, a substantially annular groove in each side tace of the drum, two openings in the periphery of the drum giving. access to the cable between said periphery and the grooves and a passage for the cable extending transversely through the drum for mutually connecting together the two grooves, the cable entering this passage clockwise on one side of the drum and leaving it anticlockwise at the other side, so that said cable can meet and leave the periphery of the drum in the same direction and in the same tangential plane.

5. The combination with a winding drum and a cable adapted to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving access to the cable inwards from the periphery to one of the grooves for one end of the cable and outwards from the second groove to the periphery for the other end of the cable, a ring adapted to partially enclose one of the grooves, and means securing said ring positively to the respective side face for tightly clamping in the groove of that face a portion of the cable intermediate its ends.

6. The combination with a winding drum and a cable adapted to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving access to the cable inwards from the pe riphery to one of the rooves for one end of the cable and outwards from the second groove to the periphery for the other end of the cable, two rings each adapted to partially enclose one of the grooves, and means securing one ring positively to each said side face, one for tightly clamping to the drum a portion of the cable intermediate its ends, and the other for loosely retaining another such intermediate portion of the cable in the respective groove.

7. The combination with a winding drum and a cable adapted to be coiled around it, of a substantially annular groove formed directly in each side face of the drum, openings in the periphery of the drum giving ccess to the cable inwards from the periphery to one of the grobves for one end of the cable and outwards from the second groove to the periphery for the other end of the cable. a passage extending transversely through the drum mutually connecting together the two grooves and within which the cable forms a bight intermediate its ends, two rings each adapted to partially enclose one of the grooves, and means securing one ring positively to each side face, respectively for tightly clamping and loosely retaining in the respective groove-s, portions of the cable at respectively opposite sides of the bight.

In testimony whereof I have aflixed my signature hereto.

ARTHUR GORDON FRENCH.
