DEVICE FOR LUBRICA'TING CAR-JOURNALS.

SPECIFICATIQN forming part of Letters Patent No. 701,029, dated May 27, 1902.

Application filed Augnst S, 1901. Serial No. 70,759. (No-model.)

T ztZZ whmn it may concern:

Be it known that 1, JOHN E. GILL, a citizen of the United States, residing at Franklin, in the county of Venaugo and State of Pennsyl- Vania, have invented certain new and useful Improvements in Devices for Lubricating Car-Journals, of which the following is a specification.

My invention relates to improvements in devices for lubricating car-journals.

One object of my invention is to provide a device of simple construct-ion for'positively supplying lubricating material to a car-journal which shall be durable, reliable, and easy of access.

Another object of my invention is to provide such a device which shall not depend upon capillary action for its supply of lubricating fluid.

These and such other objects as may be attained by my invention are illustrated in the accompanying drawings, in which- Figure 1 is a horizontal section through a car-axle box containing my invention on the 1 line 1 1 of Fig. 2 looking in the direction indicated by the arrows. Fig. 2 is a sectional view on the line 2 2 of Fig. 1 looking in the direction indicated by the arrows. Fig. 3 is a similar View to Fig. 1, showing a modified form of my device. Fig. 4 is a cross-sectional view on the line 4 4 of Fig. 3 looking in the direction indicated by the arrows. -Fig. 5 is a detail showing a modified form of my lubricating-padsupport. Fig. 6 is an enlarged detail showing the oil-supply inthe modified form of my device, and Fig. 7 is an enlarged detail showing the application of onefeature of my invention to a different form of padsupport.

Like letters of reference indicate the same parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, A indicates a car-journal box.-

B is the car-journal.

C is a thin metal plate pivotally connected to the inner arms of the pivoted levers D, which extend through the sides of the journal-box and are actuated by the weights E, by means of which the plate 0 is normally and yieldingly held snugly against the under surface of the car-journal B.

As is more clearly shown in Fig. 5, the

plate 0 is in the form of a shallow tray and is adapted to receive and hold an absorbent pad F against the under surface of the journal.

In the simpler form of my device the pad F is placed in or about the tray C, and the supply of oil is poured directly into the tray 0 and upon the pad F. This supply of oil isrcneWed from time to time by the men having charge of oiling the car-bearings. By virtue of the constant action of the weights E the pivotal mounting of the levers D and the'pivotal connection between the lovers D and the plate or tray 0 the oil-pad F is at all times kept snugly in contact with the under surface of the journal, directly below the brasses G, thereby insuring a positive and continuous lubrication of the journal-bearing. If desired,

the plate or tray C may be made of extremely thin and flexible metal, in which event a pivotal connection between the plate 0 and the levers D would not be essential, although I consider the pivoted construction preferable.

While my construction as above described is also adapted for use in connection with wicks which shall extend from the pad F to a supply of oil in the bottom of the journalbox and shall keep the pad F supplied with oil by capill-ary'action, in which event, of course, suitable openings for such wicks would be provided through the plate 0, I prefer to keep my device continuously supplied with oil by means of the modified construction shownrin Figs. 3 to 6, inclusive. In these figures it will be observed that the plate or tray 0 is provided with extensions or lips 0. These extensions may be provided on either or both sides of the tray and are intended to support corresponding extensions of the pad F, although, if desired, the extensions on the pad F may be dispensed with. These lips c extend beyond the journal B and are designed to receive oil from oil-inlet ports h, (see Fig. 6,) which connect by suitable passages with oil-cups H, mounted upon the journal-box at a point above the under side of the journal. In the simpler embodiment of this feature of my invention these oil-cups are mounted directly on the top of the journal-box, and the oil-inlet, port h opens into the journal-box immediately above the lips or extension 0, so that as the oil drops from the oil-cups it is received by the extension 0 and flows thence to the lubricating-pad F. Of course with this construction the rate of oil-supply can be regulated in any usual manner.

The device in Fig. 7 is the familiar one of alubricating-pad which is supported against the under surface of the journal by means of a spring I. Such a pad as now used is supplied with oil by means of wicks extending from such pad downwardly to an oil-reservoir. Adapting my invention to a pad of this description the pad is provided with lat eral extensions 0', which may either be extensions on the pad itself or may be merely laterally-extending devices for receiving the oil as it is fed from the oil-cups H and for carrying such oil to the pad 0.

Of course my invention is subject to various modifications in detail. For instance, each of the levers D may be independent of the other levers and may be so formed that the outer arm thereof shall act as the weights E. So, also, the exact form, contour, and dimensions of the pad-support C may be varied considerably without departing from the spirit of my invention; but these and similar modifications are all contemplated by my invention.

While in the simpler embodiment of my invention, as shown in the drawings, weighted levers are used for holding the lubricatingpad in contact with the journal, I do not wish to be limited to the use of weighted levers for this purpose, as any suitable means for yieldingly holding the levers in the desired position may be used.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a car-journal, of a journal-box, an oil-reservoir, and means for supporting said reservoir adjacent to the under side of the car-journal, said means comprising a counterweighted lever hinged directly to said reservoir and extending through, and fulcrumed on, one wall of the journal-box, substantially as described.

2. The combination with a car-journal, of a journal-box, an oil-reservoir within said journal-box, and a counterweighted yoke comprising a pair of arms which extend through and are fulcrumed in one wall of the journal-box, the inner ends of said arms being hinged to one end of the oil-reservoir, substantially as described.

3. The combination with a car-journal, of a lubricating-pad, means for yieldingly hold ing said lubricating-pad against the under surface of the car-j ournal, oil-receiving means extending laterally from said pad beyond said car-journal, an oil-cup mounted above said pad, and means for supplying oil from said oil-cup directly to said lateral extension, substantially as described.

4:. The combination with a car-journal, of a lubricating-pad, means for holding said lubricating-pad yieldingly against the under surface of the car-journal, oil-receiving means extending laterally from said pad beyond said journal, and an oil-cup mounted above said pad. whereby oil may be fed from said oil-cup directly to said oil-receiving means, substantially as described.

5. The combination with a car-journal, of a journal-box, a lubricating-pad within said journal-box, means for yieldingly holding said pad against the under surface of said journal, oil-receiving means extending laterally from said pad beyond said journal, an

oil-cup mounted upon said journal-box and means providinga passage leading from said oil cup to a point within said journal-box, whereby oil may be dropped from said oilcup directly to said oil-receiving means, substantially as described.
