DefinitionThis class is not intended to include the lubrication generally of machines of every kind; but it is intended to include those devices employed to lubricate bearing parts in a machine where such lubricating device forms no part of the machine structure. Where the lubricating device is a part of the machine, where the structure is modified to admit of lubrication, where the particular or peculiar operation of the machine governs the operation of the lubricating device, or, in other words, where there is a special combination between the lubricating device and the machine in connection with which the lubricating device is used, then such device is classified with the machine to which it belongs. Exception: Where the machine is operated by air, steam, or water and the same means used to operate the lubricator, then such lubricator belongs to this class, provided the structure of the machine is not modified. |
Lines with other classes and within this classWhere the machine is operated by air, steam, or water and the same means used to operate the lubricator, then such lubricator belongs to this class, provided the structure of the machine is not modified. An example of this exception is in this class (184), subclass 52. For further search upon this line, see Class 384, Bearings, appropriate subclasses, and also the particular class in which the machine or device itself belongs. (1) Note. Where the modification of a journal-box is no more than a hole to admit a lubricant or allow it to escape and a lubricating device is used in connection with such a journal-box, the device will go in this class (184) unless there is a particular combination between the journal-box and the lubricating device. The following classes have the noted subclasses, which are classified on the basis of the lubrication of solid, relatively movable surfaces or the materials used therefor. |
