WILLIAM C. ANTHONY, OF STREATOR, ILLINOIS,.ASSIGNOR TO ANTHONY COMPANY F STREATOR, ILLINOIS, A CORPORATION OF ILLINOIS.

SPOOL.

Application led June 5, 1924. 'Serial No. 717,927.

To all whom t may concern:

Be it known that I, -WILLIAM C. ANTHONY,

a citizen of the United States, residing at Streator, in the county of La Salle and State of Illinois, have invented a certain new and useful Improvement in Spools, of which the following is a specification.

This invention relates to a spool for use in connection with hoists. It has for one object to provide a spool which may be of small diameter and which when used with ra cable will not kink or twist or votherwise injure the cable. It has for another object to provide a spool to which cable may be attached and with rela-tion to which the cable is free to rotate so as to avoid twisting. Other objects will appear from time to time throughout the specification and claims.

My inventionis illustrated more or Vless diagrammatically in the accompanying drawing, wherein:

Figure 1 is a side elevation of the spool showing the cable in section;

Figure 2 is an end elevation of the spoo lshowing the cable in place;

Figure 3 is a detail view showing the cab'le end.

Like parts are designated by like characters throughout.

The spool is formed of a main body A which is provided with a central bore A1 and a key-way A2. The body of the spool about which the winding surface A3 is formed is preferably of varying thickness so that the spool gradually increases in diameter from one end to the other. The

y winding surface is provided with a helical depression adapted to receive the cable as it is wound onto the spool. f At one end the spool is provided with a laterally extending generally circular flange B. At the other end it is provided with a flange C. This flange is provided with an outwardly extending enlargement C1, and a laterally bent cable receiving track or portion C2. VThis portion communicateswith an open-sided cable receiving pocket D provided with the enlarged outerA end D1 and the slotted side D2. The portion C1 also carries the cable receiving depression E which is curved as shown particularly `in Figure 2. This cable receiving portion E is eurved away from the winding portion A/3 of the spool and is preferably of a curvature at least as large as the smallest curvature of thespool proper.

The cable F is normally associated with the end enlargement F1 which `may be of any suitable construction, but is larger than the smallest diameter of the pocket within which the cable is fitted.

G is a Cotter-pin mounted in the portion D1 and adapted to prevent outward movement or displacement of the cable.

Although I have illustrated an operative device, still it will be obvious that many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention; and I wish, therefore, that my showing be taken as in a sense diag imniatic.

The use and operation of my inventionV are as follows.

The spool is associated usually ,withv some form of hoisting mechanism. To attach the cable, to the spool, the Cotter-pin is withdrawn, and the cable is drawn back so that the enlarged end does not at first come into the cable receiving pocket. The cable itself is then moved side-ways through the slotted side of the cable receiving pocket and is then drawn forward so that the enlarged end is brought into and seated within the cable receiving pocket. The cotter pin is then replaced and the cable is then held against lateral or axial displacement from the spool, and at the same time a construction is provided by means of which ready renewals and replacements of cables can be carried out.

vWhen the hoisting takes place,rthe spool normally rotates in the direction of the arrow in Figure 2. The cable is thus wound about the exterior of the spool. If the spool is associated with the hoisting means, the hoisting will be carried out in the "manner described. When the movement is to be reversed, usually the device which has hoisted is allowed to return, `largely if not entirely by reason of its own weight, and the spool is thus rotated in the reverse direction and the cable unwound from 'it by the weight of the device which it has hoisted. In such reverse movement considerable momentum is frequently develol'ied.v When the cable has been completely unwound from lthe spool, thespool will frequently continue its rotation in the unwinding direction. When this takes place, the portion E engages the cable and to a limited degree the cable is wound about that portion. Since that portion is curved it does not kink or crease or otherwise injure the cable, and by reason of its curvature, it serves as a track which absorbs the shock and cushions it and stops the reverse movement of the spool, without injuring the mechanism or the cable.

By reason of the loose mounting of the cable end within the spool, it may shift and rotate within this mounting and thus twisting of the cable about the spool is prevented, and normal winding and unwinding'of the cable is permitted.

The radius of curvature of the part C1 is constantly increasing. Its initial curvature is the saine as that of the small stportion of the main winding surface of the spool proper, and its radius of curvature increases constantly from that point to its upper or outer end. Thus the cable as it winds onto the portion C1 on the receiving part E is bentabout a curve of constantly increasing radius of curvature.

I claim:

l. In combination with a winding spool, a cable adapted to be wound thereon and means on the spool adapted, in combination with the cable, to cushion and stop reverse movement of the spool in the unwinding direction.

2. In combination with a winding spool, a cable adapted to be wound thereon and means on the spool adapted to contact the cable and therewith to push it and stop reverse movement of' the spool in the unwinding direction.

3. In combination with a winding spool, a cable adapted to be wound thereon and means on the spool adapted, in combination with the cable, to cushion and stop reverse movement ofthe spool in the unwinding direction after thecompletion of the unwind-- ing.

4. In combination with a winding spool, a cable adapted to be wound thereon and means on the spool adapted to contact the cable and therewith to push it and stop reverse movement of the spool in the unwinding direction after the completion of the unwinding. i

5. In combination with a winding spool, a cable adapted to be wound thereon and means on the'spool adapted to contact the cable while the latter is under tension, and therewith to push it and stop reverse movement of the spool in the unwinding direction after the completion of the unwinding.
