Automatic lubricating device for remotely operable bowden cable

In a remotely operating device including operating means having a fixed housing and an operating lever grippably pivotally mounted on said housing;

• actuating means disposed remotely from said operating means;
• and a bowden cable including an outer wire and an inner wire for interconnecting said operating means and said actuating means, the improvement comprising an automatic lubricating means for the bowden cable, said lubricating means comprising a bracket projecting from the housing and having an inner-wire receiving hole;
• an outer-wire holding means comprising an oil cover threadedly coupled to said bracket and an oil cap slidably fitted in said oil cover, said oil cap having a recess for receiving the outer wire and an inner wire receiving hole wherein said outer wire can be adjusted by movement of said oil cover relative to said bracket;
• wherein when the oil cover is fitted to the bracket, an adjustable volume lubricating oil storage chamber is defined by the bracket and the oil cover;
• wherein the volume of said storage chamber is variable with the forward and backward movement of the oil cap, and one end of the inner wire is connected to the actuating means while the other end passes through said receiving holes and the lubricating oil storage chamber and is connected to the operating lever and one end of the outer wire is connected to the actuating means while the other end is fitted in the recess of the oil cap for moving the oil cap in a direction which increases the pressure in the storage chamber when said operating lever is pulled and for restoring the oil cap to its original position when the operating lever is released;
• and wherein the interior of the bowden cable between the outer and inner wires communicates with said lubricating oil storage chamber through the inner-wire receiving hole formed in the oil cap whereby lubricating oil flows between said inner and outer wires thereby reducing friction therebetween.
