  • Lubrication system for a wood cutting machine
    Patent number: 6363981
    Abstract: In the operation of wood cutting machines such as delimbing machines which use chain saw cutting devices, it is common to either position the lubricating oil reservoir above the chain saw cutting device to create a gravity-fed system or couple a pump apparatus to the chain saw cutting device. Both arrangements may limit the flexibility of placement of the components comprising the lubrication system. The present invention provides a lubrication system for a wood cutting machine in which a receptacle receives lubricating fluid from the reservoir by use of a source of supply pressure within the receptacle. A source of discharge pressure operates on the receptacle to transport the lubrication fluid to the cutting chain device.
