摘要： 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.

摘要： A delimbing device includes a cutting head assembly having (i) a cutting blade configured to cut branches off of a tree and (ii) a bar saw configured to cut through the tree. The device also includes a first support member supporting the cutting head assembly. The device further includes a second support member supporting the cutting head assembly. The device also includes a bearing assembly secured to the first support member and the second support member so that (i) the bearing assembly is interposed between the first support member and the second support member and (ii) the cutting head assembly can rotate relative to the second support member around an axis of rotation such that when a rotational force is applied to the cutting head assembly the cutting head assembly rotates from a first orientation to a second orientation. The bearing assembly is configured so that when the rotational force is removed from the cutting head assembly the cutting head assembly spontaneously returns to the first orientation from the second orientation.
