Description:

"The principal object of my invention is to render the pulley what is termed a self-lubricating one, it containing a reservoir for holding oil, such reservoir having one or more or a series of educts, each of which contains a reservoir for holding oil, such reservoir having one or more or a series of educts, each of which contains or is to contain a strainer consisting of a plug of leather, or other suitable material, such as will not only serve as a filter or strainer, but as a means of slowly delivering the oil or lubricating fluid upon the revolving shaft of the pulley while the latter may be in revolution."
