Description

Patented June 14, 1932 UNITED STATES FRED RADGLIFFE, OF SCRANTON, PENId'SYLVANIA CAR JOURNAL LUBRICATOB Application filed April 1, 1929. Serial No. 351,556.

The object of the invention is to provide an appliance parioularly adapted as a means of providing a constant lubricant supply for the journals when used in connection with railway cars, whether they be in urban, interurban, or fast and heavy railway service; to provide a construction of this kind that provides for working the lubricant by its proper conservation, until its lubricating properties are exhausted, thus making for high economy and efliciency and to provide a construction of this nature which is of simple form and therefore susceptible of cheap manufacture and easy application ,to the present form of rolling stock without any modification of the axles or journal boxes thereof.

With this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing, wherein:

Figure 1 is a sectional view showing a car journal and axle, the view being taken in the plane of the axis of the journal.

Fi re 2 is a sectional view on the plane indicated by the line 22 of Figure 1.

Figure 3 is an elevational view of Figure 1, but partly broken away.

In the application of the invention to practice, no modification is required in the journal 10 of the axis 11 or in the journal box 12, but the journal bearing 14 which is of the journal form is bored axially to provide a longitudinal channel 15. It is likewise drilled to provide ducts 16 communicating with the channel 15 and opening on the journal face of the hearing, so that any lubricant entering the channel 15 will find its way on to the journal 10.

In practice, it is necessary that the ducts 16 be just large enough to supply oil to the journal in the quantity needed and in practice it i has been found that ducts one-sixteenth of an inch in diameter provide the necessary supply for cars in urban service, while their diameters should be twice this or two-sixteenths for fast and heavy railway service.

The lubricant is admitted to the channel 15 through a flexible tubular conductor 17 coupled to the bearing 14 as indicated at 18, this conductor being connected withasu plytank 19 at the bottom of the latter to w ich it is connected by means of a union 20 and inter posed cook 21 by means of the latter of which the rate of supply to the channel may be controlled or cut off, depending upon the position in which the cock is set.

A supply tank 19 may be provided for each journal and suspended from the car body or some appropriate part of the running gear adjacent the journal to be supplied, as practice may dictate, or a single tank may be employed for supplying the several journals of each car, it being necessary only, in the latter plan, that a separate tube 17 be run from the tank to each bearing.

A follower plate 22 is disposed in embrae ing relation to the journal 10 diametrically opposite the bearin 14, this follower plate being depressed at the center portion as indi- 79 cated at 28, and a shield or fabric wiper 24: lies in the follower plate, filling the depres sion 23 thereof. The wiper is held yieldingly in contact with the journal 10 by means of the follower plate supporting elements 25 which, in the form illustrated are in the form of spiral s rings of which the terminals are formed with hooks 26 detachably engaged with eyes 27 on the lower edge of the bearing 14. The oil or lubricant which finds its way 30 to the journal 10 finally saturates the wiper and the journal is thus kept effectively lubrieated, and as long as the oil is active and provides good lubrication, its presence on the journal retards the flow through the ducts 16. As the lubricating properties of the oil on the journal arelost with a tendency of the journal surface to dry, the oil in the channel 15 flows more freely through the ducts. Thus as the cock 21 has been set to provide the W proper initial flow into the channel 14, the supply to the journal is thereafter automatically taken care of.

The depression of the follower plate at the center portion provides for the reception of 95 a wad of the fabric wiper and thus as a reservoir to which excess lubricant may be directed to keep the wiper'thoroughly saturated. By this means, excess lubricant is not 7 carried over the side edges of the follower plate, as would be the case were the depressed portion not provided.

For investigation of the condition of the journal, it is frequently necessary to remove the follower plate and this may be readily done without detaching the springs 25, it being only necessary to slide the follower plate out of the loops formed by the springs. In

the replacement of a new spring, it is a comparatively easy matter to engage it with the eyes 27 plate, thereafter forcing the latter in between the journal and the springs. Obviously the tank may be vented to permit the ready flow of the oil therefrom.

The invention having been described what claimed as new and useful is:

In combination with a car journal and bearing therefor, a supply tank in valved communication with the bearing, and a follower plate disposed vdiametrically opposite to the bearing and yieldingly impelled toward the j0urnal,.the follower plate being provided with a mat interposed between it and the journal, and having a depressed portion at the center filled with the material of the mat. In testimony whereof he afiixes his signature. v
