Lubricant applicators

Apparatus for constantly supplying lubricant to a bearing, comprising a container having an outlet in an end thereof and adapted to be connected to the lubricating system of a bearing, a separator movably mounted in the container spaced from and movable towards said outlet and dividing said container into a lubricant chamber on the outlet side thereof and a gas chamber on its opposite side, said separator including means for preventing gas from moving from the gas chamber into the lubricant chamber, electrical current and gas generating means in the container and in communication with the gas chamber, said current and gas generating means including a cell having therein a cathode spaced from an anode, an electrolyte confined within the cell and at all times in contact with the cathode and the anode, means in the cell preventing the flow of electrolyte from the cell while permitting gas to flow therefrom to be gas chamber, an electrical circuit in the container external of the cell and extending from said cathode to said anode, and switch means in the circuit for, when activated, completing said circuit so that an electrical current flows through said electrolyte between said cathode and said anode to cause generation of gas by said electrolyte which exerts pressure on said separator to force lubricant in said lubricant chamber out through said outlet.

Apparatus for constantly supplying lubricant to a bearing, comprising a container having an outlet in an end thereof and adapted to be connected to the lubricating system of a bearing, a diaphragm near an end of the container remote from said outlet expandible to force lubricant in the container out through said outlet, a gas chamber in the container behind the diaphragm and in communication with the diaphragm, a cathode spaced from an anode in said chamber, an electrical circuit outside the chamber for connecting the cathode to the anode, a battery connected in said electrical circuit, an electrolyte in continuous contact at all times with the cathode and the anode and switch means for, when activated, completing said electrical circuit so as to cause electrical current flow through said electrolyte and the consequent generation of a gas by said electrolyte which exerts pressure on the diaphragm to force lubricant out through said outelt.

Apparatus for constantly supplying lubricant to a bearing, comprising a container having an outlet in an end thereof and adapted to be connected to the lubricating system of a bearing, a diaphragm, disposed near an end of the container remote from said outlet, which is expandible to force lubricant in the container out through said outlet, a spherical gas chamber in the container behind the diaphragm, said chamber comprising a cathode and an anode arranged around a central axis and formed by interleaved segments separated from each other by insulating means therebetween, an electrical circuit connected at one end to the cathode segments and at an opposite end to the anode segments, a battery connected in said circuit, an electrolyte in the chamber in continuous contact at all times with said anode and said cathode, switch means for, when activated, completing said electrical circuit through said electrolyte so that a gas is generated by said electrolyte and a gas passage extending from above the electrolyte in the chamber out of said chamber for directing generated gas against the diaphragm to force lubricant out through said outlet.
