Figil is an *elevational' View of a drumprovided with the cable attaching means embodying this invention.

Fig. 2 is an end elevational view of the drum.

Fig. 3 is an enlarged fragmentary, sectional view taken on line III--III of Fig. 1.

Fig. 4 is a sectional View taken on line IVIV of Fig.3.

Fig. 5 is a fragmentary, sectional view taken on line V-V of Fig. 3.

Throughout the several views like reference characters refer to similar parts and the numeral ll] designates a drum suitable for receiving a cable '0 thereon. This drum is provided with the usual cylindrical shell or body l2 about which the cable is to be wrapped and also end walls I4 which extend beyond said drum shell to form flanges IS. The inside connection between the flange and cylindrical shell is provided with a fillet I8. A drum shaft 2|] is axially disposed in the drum by welding as at 22 or by any other of the well known means so that they turn together. One of the end walls I4 is radially slotted at 24 to register with a slot 26 formed in the cylindrical shell l2. These slots are of substantially the same width and are adapted to receive a bell-crank lever 28 with its one arm 30 extending inwardly into said drum and its other arm 32 extending radially to protrude into the drum cavity.

When the cable C is in position, as shown in the drawings, it will be noted that it is slightly olT-set diagonally of the axis of the drum as shown in Figs. 4 and 5. The bell-crank; lever hole 42 is preferably formed to present sharp corners at 56. When it is found necessary to remove the cable, the operator turns the screw 46 so as to move the lever arm 30 downwardly toward the drum axle, thereby releasing the grip of the bell-crank lever on cable C so that the cable will be free to be moved from its position in the bell-crank lever. After the cable has been removed, the new cable can be inserted and the screw 46 turned in the reverse direction to force bell-crank lever about its fulcrum or bearing 34 so as to force cable diagonally of the axis of the drum into the corner formed by the shell 12 and the end wall 14. By means of this type cable engaging means the cable is secured against undue distortion and therefore may be more tightly gripped than would be the case if the cable was simply forced against a planar surface.

Since it is quite evident that the bell-crank lever is so constructed that it engages the cable opposite the fillet I 8, that portion of arm 32 opposite the cable might be removed without interfering with the operation of the lever. However, when constructed as shown With the hole 42 in arm 32 less material will need to protrude into the path of travel of the cable.

It will be noted that the bell-crank lever is easily removed from its position in the drum by simply removing the screw 46, thus making it possible to quickly insert a bell-crank lever having an opening 42 suitable for receiving the particular cable to be used.

Minor changes might be made both in construction and arrangement of the parts without departing from the spirit of the invention.

What I claim as new and desire to be covered by Letters Patent is:

1. In a device of the character described, a hollow drum having a cylindrical body and a radial flange, a bell crank lever fulcrumed within said drum and having an apertured arm intersecting the juncture of said cylindrical body and radial flange to receive a cable, and means to rock said bell-crank lever about its fulcrum whereby said cable is tightly gripped between said cylindrical drum, radial flange and bell crank lever.

2. In a device of the character described, a hollow drum having a cylindrical body and a radial flange, a bell-crank lever fulcrumed in said cylindrical body with one of its arms positioned to intersect the juncture of said radial flange and cylindrical body, said arm having an opening formed therethrough suitable for receiving a cable therethrough, the other arm of said bell-crank lever being provided with an adjustable screw operable to rock said bell-crank lever on its fulcrum whereby the cable thread through said lever arm will be securely gripped between said bell crank lever and said drum.

3. In a device of the character described, a drum having a cylindrical body and a radially disposed end flange, a bell-crank lever fulcrumed within said cylindrical body with its one arm positioned to extend from said cylindrical body to rest against a cable positioned at the juncture of said cylinder body with said end flange, and with its other arm positioned substantially parallel with the axis of said drum and provided with an adjustable screw operable to oscillate said bellcrank lever whereby to securely grip said cable against said drum.

4. In a device of the character described, a drum mounted on a shaft and having a cylindrical body and a radially disposed end flange, a bell-crank lever fulcrumed within said cylindrical body with its one arm positioned to extend from said cylindrical body to rest against a cable positioned at the juncture of said cylinder body with said end flange, and with its other arm positioned substantially parallel with the axis of said drum and provided with an adjustable screw having its inner end resting against said shaft and operable to oscillate said bell-crank lever whereby to securely grip said cable against said drum.

5. In a device of the character described, a cylindrical drum radially slotted and mounted for rotation, a bell-crank lever fulcrumed within said drum slot with a perforated end thereof protruding from the periphery of said drum to receive a cable therethrough, and adjustable means operable to oscillate said lever about its fulcrum to securely grip said cable against said drum.

6. In a device of the character described, a cylindrical drum radially slotted and mounted for axial rotation, a lever fulcrumed within said drum slot and having an apertured end portion extending outwardly from the periphery of said drum to receive a cable therethrough, and a screw operatively mounted on the other end of said lever operable to force said lever about its fulcrum and to force said cable against said drum whereby it is secured to said drum.
