Hydraulic powered lubricator and sprayer

Claim 1

Apparatus powered by hydraulic fluid pressure for the delivery of liquid and semiliquid materials, such as a viscous fluid, a thixotropic gel or a gel-type grease, said apparatus including the combination of: means for pressurizing hydraulic fluid, a hydraulic motor powered by the pressurized hydraulic fluid, valve means for controlling said hydraulic motor, a container forming a supply reservoir for said liquid and semiliquid materials, pump means driven by said hydraulic motor to withdraw the material from the container while pressurizing the withdrawn material, an open-ended collar having an open discharge orifice in the side wall thereof, a conduit line to interconnect said pump means with the open discharge orifice of said discharge means for discharging pressurized material, resilient wiper means at the opposite ends of said collar to form an internal chamber wherein the pressurized material delivered by said conduit line is discharged from said open orifice onto the surface of an article while passing through the collar between said resilient wiper means, and means to control the discharge of the material from said open discharge orifice only by controlling the pressurization of the material by said pump means.

Claim 9

A method of discharging liquid and semiliquid materials including a thixotropic gel onto a surface of a cable prior to the passage of the cable into a conduit, said method including the steps of: attaching to an end of said conduit an open-ended collar having an open discharge orifice in the side wall and resilient wipers at opposite ends, thereby forming a chamber to discharge said materials onto the cable, using a hydraulically-driven pump to withdraw and pressurize such material from a reservoir to flow within a conduit line, continually discharging the pressurized material within the conduit through said open discharge orifice that essentially remains in open communication with the conduit line and the chamber in a directly dependent relation to the existence of pressurized material by the hydraulically-driven pump, terminating the discharge of the material by the discharge means only by diverting the supply of hydraulic fluid from the pump to thereby terminate pressurization of the material withdrawn from the reservoir, and detaching said open-ended collar from said conduit.

Claim 10

A method of discharging liquid and semiliquid materials including a thixotropic gel onto a surface of a cable prior to the passage of the cable into a conduit, said method including the steps of: attaching to an end of said conduit an open-ended collar having an open discharge orifice in the side wall and resilient wipers at opposite ends, thereby forming a chamber to discharge said materials onto the cable, using a hydraulically-driven pump to withdraw and pressurize such material from a reservoir to flow within a conduit line, continually discharging the pressurized material within the conduit through said open discharge orifice that essentially remains in open communication with the conduit line and the chamber in a directly dependent relation to the existence of pressurized material by the hydraulically-driven pump, terminating the discharge of the material by the discharge means only by diverting the supply of hydraulic fluid from the pump to thereby terminate pressurization of the material withdrawn from the reservoir, and detaching said open-ended collar from said conduit.

Claim 12

A method of applying a high-stress lubricant in the form of a thixotropic gel onto a surface of a cable prior to passage of the cable into a conduit, said method including the steps of: attaching to an end of said conduit an open-ended collar having an open discharge orifice in the side wall and resilient wipers at opposite ends thereof forming a chamber to discharge the thixotropic gel lubricant onto the cable, stressing the thixotropic gel lubricant up to pressures of the order of 10,000 pounds per square inch by using a hydraulically-driven pump to pressurize the gel withdrawn from a reservoir and thereby increase the viscosity of the gel to flow within a conduit line, continually discharging the stressed thixotropic gel lubricant from the conduit through the open discharge orifice toward the surface of said cable to receive the high-stress lubricant, terminating the discharge of the thixotropic gel lubricant only by diverting the supply of hydraulic fluid from said pump to thereby terminate the pressurization of the gel withdrawn from the reservoir, and detaching said open-ended collar from said conduit.

Claim 13

A method of applying a high-stress lubricant in the form of a thixotropic gel onto a surface of a cable prior to passage of the cable into a conduit, said method including the steps of: attaching to an end of said conduit an open-ended collar having an open discharge orifice in the side wall and resilient wipers at opposite ends thereof forming a chamber to discharge the thixotropic gel lubricant onto the cable, stressing the thixotropic gel lubricant up to pressures of the order of 10,000 pounds per square inch by using a hydraulically-driven pump to pressurize the gel withdrawn from a reservoir and thereby increase the viscosity of the gel to flow within a conduit line, continually discharging the stressed thixotropic gel lubricant from the conduit through the open discharge orifice toward the surface of said cable to receive the high-stress lubricant, terminating the discharge of the thixotropic gel lubricant only by diverting the supply of hydraulic fluid from said pump to thereby terminate the pressurization of the gel withdrawn from the reservoir, and detaching said open-ended collar from said conduit.
