  • a resilient spring bumper 37 is mounted inwardly of the inner surface of the side frame member and in position to be engaged by the leg portion 22 of the festoon arm 18 to limit pivotal movement of the festoon arm 18 around its pivot 19 in a counterclockwise direction.
  • a reaction member 36 attached to side frame member 5 limits the clockwise pivotal movement of the festoon arm caused by self energization of brake means 3,'hereinafter described in greater detail, upon termination of withdrawal of the wire.
  • a hook member 40 is pivotally mounted on the pin 17 supporting sheave 16 and which is adapted to be engaged with a pin 42 on the leg portion 24 of the festoon arm 18 to hold the festoon arm 18 well forwardly of the frame.
  • brake means In connection with the aforementioned components providing for substantially constant tension of wire withdrawn from a reel over a predetermined range of move ment of the festoon arm, it will be observed that brake means, indicated generally at 3, provides for the retarding rotation of the reel so that it does not overrun wire being withdrawn from the coil.
  • the brake means 3 as best seen in FIGURES 1, 3 and 4 comprises a brake drum 44 suitably mounted on shaft means 45 of the reel and shaft assembly 2, and from which a pair of pins 46 project axially and into openings provided in the adjacent reel side plate 47.
  • the brake means 3 as seen in FIGURES 1 and 3, further comprises brake shoe means 48 defined by a pair of leg members 52 and 53 which at their diverging outer end portions carry brake shoes 54 and 55 for braking engagement with the P ripheral surface of the brake drum 45.
  • a transverse reinforcing plate 56 connects the leg members 53 and 54 inwardly of their diverging end portions, and a spring holder, in the form of a rigid hollow pipe 57, is mounted on the plate 56 to lie between parallel spaced apart upper portions 58 and 59 of the arms 52 and 53.
  • a plate member 60 extends across and is secured to the upper ends of the legs 58 and 59.
  • Brake spring means in the form of coil spring 62 is received and supported in the rigid hollow pipe 57.
  • Brake shoe mounting means for mounting the brake shoe means 48 on the festoon arm 18 comprises a slide member 65 mounted between the parallel portions 58 and 59 of the legs 52 and 53 of the brake shoe means for movement between. end plate 60 and the open upper end of hollow pipe 57.
  • the slide member 65 is formed with an opening into which a pin 66 carried by the leg portion 23 of the festoon arm 18 is received.
  • the slide 65 is thus mounted for sliding relation between the arms 58 and 59 of the brake shoe means in response to movement of the festoon arm 18.
  • a coil spring 67 extends between festoon arm 18 and brake shoe means 48 to position the latter with respect to the brake drum 44.
  • the brake spring means 62 will be loaded between the slide 65 and the plate 56 of the brake shoe means to yieldingly bias or engage the brake shoes 54 and 55 into engagement with the periphery of the drum over a predetermined range of movement of the festoon arm toprevent the reel from overrunning the wire being withdrawn from the reel.
  • the slide 65 Upon movement of the festoon 18 to a predetermined end position in the clockwise direction at which the slide 65 fully collapses the brake spring means 62 within the hollow pipe 57, the slide 65 will then rigidly engage the hollow pipe 57 and, when this occurs, the brake shoe means 48 will self energize into substantially non-yielding engagement with the surface of the brake drum 44.
  • the brake torque thus applied to the brake drum is many times that of the yielding frictional braking action in the normal operation of drawing wire w from the reel.
  • large or high brake torque through self-energization of the brake shoe means arrests movement of the reel and holds it against rotation.
  • a small or slight releasing force is sufiicient for the wire to be withdrawn from the spool.
  • the self-energizing action of the brake means provides for application by toggle action of the brake shoe means to the brake drum.
  • the apparatus shown in the drawings provides for the facile and easy manual loading of a heavy reel and wire coil thereon onto the frame 1.

  • the cam followers 80 and 81 are preferably low friction rollers and are secured to the ends of the shaft 46 in any suitable manner.
  • Brackets '82 and 83 as best seen in FIGURES 1 and 2 have latches 84 and 85 pivotally mounted thereon so that when the cam followers 80 and 81 are supported on the cam follower surfaces 10 of the supporting means 8 and 9 the latches 84 and 85 may be swung in position over the cam followers to retain the reel and drum assembly in position on the frame as shown in FIGURE 1.
  • the festoon arm 18 In loading a reel with a coil of wire thereon onto the frame the festoon arm 18 is first disposed to its end counterclockwise position to dispose the brake shoe assembly 3 in position free of the brake drum of the reel to be placed on the frame.
  • the festoon arm is held in such position as above described by the aforementioned latch and pin 42.
  • the reel is then positioned with the portions of the peripheries of the reel sides in engagement with the inclined surface 71 of the tread 70, and upon movement of the reel on the peripheries of its rims inwardly of the frame, the reel is raised slightly to dispose portions of the shaft means onto the surfaces 75 of the ramps 73 and 74 with the reel then rolling into the frame on these ramp surfaces to the point where the cam followers $0 and 81 engage with the cam follower supporting surfaces 1% of the support means 8 and 9, respectively. Thereafter, the latches 84 and 85 are disposed to the position shown in FIGURE 1 to retain the reel in position on the frame.
  • the latch 40 may then be released from the pin 42 and the festoon arm moved in a counterclockwise direction to engage the brake shoes of the brake shoe means with the surface of the brake drum. Thereupon, upon stringing of the wire through the festoon as before described, the let-off apparatus is ready for operation. It will be observed that in loading a reel onto the let-01f stand as above described that only a portion of the necessary work is achieved by rolling the peripheries of the reel sides up inclined surface 71 of the tread 70. A preliminary roll of less than one inch is sufficient to easily roll the reel to the point at which shaft means 45 is deposited onto surfaces 75 of the ramps 73 and 74.
