Abstract: A dispensing device is pulled through a conduit while a coating material, such as a lubricant, is forcibly dispensed from the dispensing device and spread along the interior surface of the conduit. The dispensing device has an elongate tubular body with a hollow interior portion adapted for containing a supply of the coating material and having an opening in the body through which the coating material is dispensed. An elongate connector extends axially into the hollow interior of the elongate body through the leading end thereof and is connected to a piston located inside the hollow body. When the dispensing device encounters a frictional resistance as it is pulled through the conduit, the piston is pulled forwardly in the hollow body to forcibly dispense coating material from the dispenser and the dispenser thereafter spreads the coating material along the wall of the conduit.

Abstract: A wheeled cart adapted for facilitating transporting a plurality of coils of wire from one location to another on a construction site and for facilitating withdrawing the wire, as needed. The cart comprises a skeletal frame having a plurality of interconnected vertical upright and horizontal cross members defining open areas therebetween. Dispensers for coiled wire are suspended from certain of the horizontal members, the dispensers each having a generally horizontally oriented supporting base for supporting a coil of wire thereon and being adapted to facilitate freely unreeling the wire from the coil. Means is provided on the horizontal frame members beneath each of the dispensers for restricting lateral movement of the dispensers during movement of the wheeled cart from one location to another and during withdrawing of wire from the dispenser. The cart is also adapted for carrying and dispensing wire from spools.

Abstract: A wire reel for dispensing wire from coils or cartons including rotatable means for paying out the wire without twists or kinking, means to retard the rotation of the reel when wire is being withdrawn therethrough, means for quick disconnect of the suspending lines for the base plate from the plate and means for secure assembly of the disconnect means from the suspending means.
