Abstract: A flowable lubricant is metered in pulses to a chain drive under the control of the computer programmed to respond to measurement of the chain drive speed so that, when the speed of the chain drive is below a threshold level above which centrifugal force can cause loss of lubricant, the lubricant can flow in pulses to the chain drive. When, however, the speed of the chain drive rises to the threshold value, the pulse dispenser is blocked and the supply of lubricant pulses is terminated. The lubricant pulses which are not supplied during the interval are stored. When pulse supply of lubrication is restored, the stored lubricant pulses are supplied.

Abstract: An automatic lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected to a machine to be lubricated and an opposite side, a piston in the vessel movable forward toward the one side to force the lubricant from the outlet, and an electric drive connected to the piston and electrically energizable to advance the piston forward. An electric power source is connected via an electrical circuit to the drive for periodically energizing the drive and thereby advancing the piston an increment and pumping a dose of the lubricant from the outlet.

Abstract: An automatic pressurizable lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected to a machine to be lubricated, a cover, and a cap fittable like a piston in the vessel and forming with the cover a substantially closed compartment holding a supply of a reactive liquid. The cover is formed with a seat opening into the compartment and extending along an axis and a removable partition closes the seat and segregates it from the liquid-holding compartment. A cartridge body fittable in the seat is movable therein between a partially inserted position and a fully inserted position and is formed unitarily of plastic with a cylindrical collar formed with a pair of diametrally opposite cutouts and having an outer end. The outer end moves from nonengagement with the partition in the partially inserted position to engagement through the partition in the fully inserted position.

Abstract: A lubricant dispenser has a housing, a piston subdividing the housing into a pair of compartments one of which is generally closed and the other of which is adapted to be connected to a machine to be lubricated, a body of a reactive liquid in the one closed compartment, and a body of a fluent lubricant in the other compartment. The piston is movable against the lubricant body to force same from the housing to the machine. A reactive element in the one compartment can react with the liquid and form a gas when immersed in the reactive liquid to push the piston with the gas against the lubricant body and expel the lubricant from the housing. The reactive element is constituted as a coherent block by a multiplicity of particles of an active substance capable of reacting with the liquid and forming a gas on reaction therewith and a multiplicity of particles intermixed and in electrically conductive engagement with the active particles of a substance that is substantially less reactive.

Abstract: A cartridge containing a current-generating cell and a gas-generating cell electrically connected therewith is received in a cylindrical seat of a bottom part of a unit fitting into an end of a lubricant receptacle housing and closing this end thereof. The lubricant receptacle housing can be connected by a fitting at the opposite end of a machine to be lubricated. The unit has a cover cap on its bottom part which can be forced off the latter when gas is generated in the unit to displace the lubricant out of the housing.

Abstract: An automatic pressurizable lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected via a conduit to a machine to be lubricated and another open side and a cover engaged over the other side and fitted with a cap fittable snugly like a piston in the vessel and forming with the cover a substantially closed compartment holding a supply of a reactive liquid. The cover is formed with a seat opening into the compartment. A gas-generating cartridge fits into the seat and has an element capable of reacting with the liquid and forming a gas. A removable partition closes the seat and segregates it from the liquid-holding compartment. The cartridge is constructed so as to remove the partition and contact the element with the liquid for generating gas in the compartment and forcing the cap like a piston away from the cover into the vessel to pressurize the fluent lubricant therein.

Abstract: A dispenser of a flowable medium, especially a lubricant, with a flexible wall tube forming the pumping chamber which is connected to a container for the flowable medium by a check-valve and feeds a dispensing nozzle. The pumping chamber is deformed by a plunger actuated by a lever in turn displaced by a solenoid whose linearly displaceable rod bears upon the lever.

Abstract: A lubricating and cleaning unit for chains and rails has a pair of parallel shanks of a shoe and a crosspiece receiving a U-shaped brush in a groove which distributes lubricant through bores in the shanks and crosspiece of the brush to respective bristle bundles. One or more automatic feeders can be connected to threaded openings of the lubricant-distribution bores opening along the sides of the body. The unused openings are closed by plugs.

Abstract: The invention concerns a device for the continuous supply of liquid or viscous mediums, in particular of lubricants, and includes a container subdivided by means of a separation device or similar into a chamber for holding the medium and a pressure gas chamber, and a device which can be triggered into action at any time for the electrochemical generation of gas which builds up pressure inside the pressure gas chamber, causing the separation device to expand or shift, which in turn causes the medium to be dispensed.
