Abstract

6225. Freitag, A. April 3. Journals; lubricating.-Relates to lubricating- devices for horizontally-mounted shafts, eccentrics, trunnions, crank-pins, &c. Fig. 2 shows the application of the invention to a horizontal shaft. An oil reservoir c is formed in the bearing d, and communicates with the shaft a by passages f. The ends of the bearing form chambers enclosed by overflow edges e, which take into grooves b in the shaft, thereby permitting the lower part of the shaft to dip into the oil bath, the oil being carried round or sucked up by the rotating shaft. The sharp edges h on the shaft return the oil to the reservoir. The oil is distributed by the lubricating- channels g, and is supplied through apertures closed by a screwed stopper i, and in the end chambers are holes, closed by screw stoppers, for cleaning purposes. In Fig. 4, the invention is shown as applied to a crank-pin and connecting- rod end. The crank-pin l is formed with a collar m for retaining the end n of the connecting-rod. A channel in the lower portion of the end acts in conjunction with chambers c to form an oil reservoir. The chamber nearest the crank is formed by a divided plate o, having a central aperture the edges e of which take into an annular groove b in the crank-pin. The other chamber is formed by a plate covering the outer end of the crank-pin. Oil is supplied, through an opening closed by a plug q, to a ring groove s surrounding the collar and communicating with the oil reservoir. An eccentric may be similarly lubricated from a reservoir within the strap, formed by overflow edges entering annular grooves in the eccentric.
