Abstract
A strand being pulled through a conduit is automatically lubricated.
Claims40
Apparatus comprising
- a pump to force a viscous lubricant from a supply to a lubricator at which the lubricant is to be dispensed onto a strand that is being pulled through a conduit, the pump including a gear pump,
- a battery-powered motor to drive the gear pump, and
- a foot pedal to control the motor.
An apparatus comprising
- a pump to force a lubricant from a standard-sized bucket of lubricant to a lubricator at which the lubricant is to be dispensed onto a strand that is being pulled through a conduit, the pump including a flange configured to mate with an opening of the bucket and support the pump above the bucket, and
- an auger that draws lubricant from the bucket, the auger being driven by a motor, the motor being mounted above the flange, the auger projecting below the flange.
A method comprising
- drawing a lubricant from a supply to a reservoir using an auger,
- forcing the lubricant from the reservoir between two meshing gears into a supply line, and
- delivering the lubricant through the supply line to a lubricator to apply a lubricant to a strand as it is pulled through a conduit.
Apparatus comprising
- a lubricator at which lubricant is to be dispensed onto a strand that is being pulled through a conduit,
- a pump to force a viscous lubricant from a supply to the lubricator, the pump comprising a pair of gears to force the lubricant from a reservoir to an outlet for a supply hose,
- a battery powered motor to drive the pump, the motor having different transmissions to vary the amount of lubricant applied to the strand, and
- a mechanism to feed lubricant from the supply to the reservoir, in which the mechanism comprises an auger geared to the gear pump, and in which the anger is driven to oversupply the reservoir relative to the amount of lubricant being pumped by the gear pump.
