OILING DEVICE FOR JOURNAL BOXES.

Application ledFebruary 7, 1924-..k Serial No. 691,151. i

To all 'whom t may concern:

Be it known that I, CHARLns B. ROYAL, a citizen of the United States, residing at Chicago, in the ,county of Cook and State 5 of Illinois, have invented a new and useful Improvement inOiling Devices for Journal Boxes, of which the following is a specification. Y

This invention lrelates to means for lul bricating journal boxessuch as are used on' trucks of railway cars and the like.

The space beneath theV journal and with-` in the journal box is commonly filled with waste and oil is poured over this. This l oil is carried yto the journal by capillary attraction. "For many reasons this method of oiling the journal is very unsatisfactory.

The primary object of this invention is oil from the pocket in the bottom of the journal box to the journal as the latter rotates.

This and other objects are accomplished by this invention which is fully described in the following' specification and shown in the accompanying drawings in which:

Figure 1 is a longitudinal section through the journal box on the line 1-1 of Fig.,2;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1; and

Fig. 3 is a partial developed view of the` flexible oiling member.

The invent-ion is applied to a standard journal box having a housing 10, such as is commonly used on the trucks of railway cars and the like. The housing 10 surrounds the journal 11 on the endof the shaft 12, the journal supporting suitable bearing members 13 and 14 such as are commonly employed for this purpose.

The lower part of the housing 10 has a bottom 15 providing a pocket 16 beneath the journalfll. Within the space I have provided an oiling device comprising a flexible member made up of a seriesof felt strips 17 secure-d in any suitable manner as by stitching to an endless belt 18 which may be made of any suitable material such as cotton fabric.

Thisiexiblc member passes over two rollers 19 and 20 which are journalledvupon pins 21 and 22 which in turn'are carried by crossed bars 23 and 24 which are pivotally connected near their center, thelower Aend bearing upon theihousing bottom 15.

to provide a suitable means for conveying' AiS as follows:

These bars are connected by pins 25 .and 26 upon which is mounted a roller 27 which has a grooved or spiked surface 28, the latter bearing upon the inner surface of the flexible-member at ,the bot-tom of its swing. An operating lever 29 is connected tothe pin 25..

A tension spring 30 at each rend of the bearing connects the bars 23 and 24 'and serves to force the rollers 19 and 2O toward each other thereby pressing the felt strips 17 into contact with the journal.

In addition to the action already described, cil is fed to the journal by the flexible member which acts as a wick, conveying oil by capillary attraction from the y body of oil in the bottom of the journal box.

The method of operation of the device As the axle turns there is a small amount of friction betweenthe journal 11 and felt strips 17 which causes the flexible member to gradually move in the direction of the surface of thev journal with which it is in contact, but at a very much slower rate of speed. As this occurs the felt strips 17 pick up oil from the'k bottom of the journal box and carry it around into Contact with the journal, thereby thoroughly lubricating the same. In case, how` everit is desired that oil shall be quickly fed to the bearing, particularly when the bearing has remained stationary for a long period of time, the'operator raises the housing cover 10a and reaches in through the front opening, moves the lever 29, thereby causing the flexible member to be moved. thus bringing a fresh supply of oil into contact with the journal.

While I have shown and described certain embodiments of my invention, itis to be understood that it v1s capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my in-L vention as `b-roadly as possible in view of the prior art.

I claimz' .1. In a railway journal box, in combination, a journal having bearing upon its upper surface, a bearing housing surrounding said journal and having an oil pocket beneath the same, a flexible member adapt ed to dip -into said oil and to have frictional engagement With said journal to Cause said flexible member to move to carry oil to said journal, said flexible member oomprising a series of parallel strips of felt Secured to an endless fabric belt.

2; In a railway journal box, in combination, a journal having bearing upon its upper surface, a bearing housing surrounding said journal and having an oil pocket beneath the same, a flexible member adapted to dip into said oil and to have frictional engagement with said journal to cause said flexible'member to move to carry oil to said journal, said flexible member comprising a series of parallel strips of felt secured to an endless fabric belt, and meansv for mov ing said flexible member independently of the movement of the journal.

3. In a railway journal box, in combination, a journal having bearing upon its upper surface, a. bearing housing surrounding said journal and having an oil pocket beneath the same, a flexible member adapted to dip into said oil and to have friotional engagement with said journal to cause said flexible member to move to carry oil to said journal, said flexible member comprising` a series of parallel strips of felt secured to an endless fabric belt, and a sprocket engaging said flexible member for independently moving said member.
