Patented Jan. 20, 1931' PATENT OFFICE FRED RADCLIFFIL OF PHILADELPHIA, PENNSYLVANIA CAR-JOURNAL OILER Application filed Septeniber 20, 1929. Serial 1T0. 894,026.

7 The object of the invention is to provide a device for oiling the journals of street and railway car axles by the continuous supply of oil from a reservoir or tank carried on the journal box; to providea device of this nature in which the oil is fed from the reservoir or tank to an oil channel in the bearing and thence transferred to the journal through appropriate ducts connecting with the channel, the means connecting the reservoir with the channel being valve controlled and belng within the box so as to reduce to a minimum the possibility of its being tampered with by unauthorized persons; to provide a journal oiler of which part .of the equipment comrises a wiper plate disposed opposite the caring and yieldingly impelled against the journal and carrying an oil absorbent material in contact with the journal; and to provide a construction which is of simple form, susceptible of cheap manufacture and ofa character that will permit its installation on existing equipments without any modifications of the latter.

With this object in view the invention consists in a construction and combination of parts of which a preferred embodiment 1s illustrated in the accompanying drawings,

wherein:

Figure 1 is a sectional view of a conventional journal box showing the invention applied in operative position.

Figure 2 is a side elevational view of a portion of the journal box broken away to expose the bearing and wiper plate.

Figures 3 and 4 are transverse sectlonal views on the planes indicated by the l1nes 3-3 and 44 respectively of Figure 1.

Figure 5 is a bottom plan view of the wiper plate and its attendant supporting spring.

As illustrated, the invention is shown employed in connection with a conventional journal box 10 provided with a spr n actuated cover plate 11 which, when raise permits access into the interior of the box for any attention that may be necessary to the bearing 12 and its attendant wi er plate 14. The bearing 12 is of the usual orm and is seated under the wedge 15 in the usual manner but to incorporate the advantages of the. invention is provided with a longitudinal channel 16 with which spaced radial ducts 17 communicate and permit any oil received into the channel flowing on to the journal 18.

The oil supply is carried in a tank or reservoir 19 mounted on top of the journal box and secured thereto in any appropriate manner,

the tank extending out over the hinge 20 of the cover 11. To clear the latter and the actuating spring of the cover, it is formed with a clearance space 21. The removable plug 22 closes a filling opening'on/top of the tank through which the latter {may be supplied with oil.- The contents of the tank are subject to atmospheric pressure by reason of the vent formed in the top as shown in Figure 1;

or the removable plug 22 may be provided with such vent hole.

To conduct the oil from the tank or reservoir to the channel 16, there is provided a flexible tubular member 23 one end of which is taped in to the forward end of the hearing, as indicated at 24 and the other end of which is connected with a valve 25 which is in com munication with the tank 19 at the bottom. The plug 26 of the valve is formed with a kerf 27 by means of which a screw driver or similar tool may be employed to actuate the plug and secure the desired seating of the latter to permit the flow of oil from the reservoir into the channel at approximately the rate it is required. The flexible tubular conductor 23 and its attendant valve are housed within the journal box so as to be unexposed and where the likelihood of tampering with' the valve by unauthorized persons is reduced to a minimum.

The wiper plate 14 is made preferably of I formed and is therefore an integral part of the latter but which is provided with an, additional reinforcing arm 33 extending from it to the upper convolution of the spring. The s ring is of a compression form and when the sldes of the 100 30, the spring bearing on the bottom of the journal box forces the wiper plate towards the journal, keeping the absorbent mat 29 in con-. tact therewith, so that the oil which flows through the ducts 17 and on through the journal is caught by the mat and therefore retained for use-on the journal.

The wiper-platemay be readily moved when desired by raisin the cover 11 and thereafter depressing t e plate and withdrawing itand its supporting spring from the box. Thus the removal of mats 29 is rendered easy and the substitution of the new wiper plate when necessary made possible without difiiculty,

Since the oil that passes from the ducts on to the journal is not dissipated by being deposited on the bottoin'of the journal box but is caught by the wiper plate and thereby kept into contact with the journal to effectively exhaust its lubricative properties, the supply from the reservoir may be only at the rate necessary to accommodate the ournal in addition to what is conserved by the wiper plate. The invention having been described what is claimed as new and useful is:

1. A car journal oiler for use in connection with a journal box having a bearing mounted therein and formed with a longitudinal channel, the journal box having an access opening closed by a cover plate, a reservoir mounted on top of the box, a flexible tubular conductor connecting the reservoir with the channel, and

a valve inter osed in said conductor, the valve and the con uctor being interior to the journal box.

2. A car journal oiler for use in connection with a journal box having a bearing mounted therein and formed with a longitudinal channel, the journal box having an access opening closed by a cover plate, a reservoir mounted on top of the box, a flexible tubular conductor connecting the reservoir with the channel, and a valve interposed in said conductor, the valve and the conductor being interior to the j ournal box, the valve havin its plug formed with a screw kerf for actuation by a screw driver or like tool and being disposed close to the access opening.

In testimony whereof he aflixes his signature.
