Patented June 17, 1930 UNETED STATES PATENT @FFME MARTIN I, HARGER, 0F NEVELL, PENNSYLVANIA, ASSGNOR OF ONE-THIRD TO CHARLES O. DOWNEE, OF NEVTELL, PENNSYLVANIA, .AND ONE-TI-IERD T0 KERFOQT W. DALY, OF CHARLEROI, IPENNSYLVANA JOURNAL BOX Application filed October 31, 1927. Serial No. 229,844.

This invention relates to journal boxes for vehicles and has been particularly devel oped in its application to journal boxes for railway cars for transporting ore and other 5 commodities in bulk, ancL which at the place of delivery are not uncommonly emptied by raising the cars bodily and overturning them. Suitable apparatus is in such case' provided for engaging the entire car and The invention resides primarily in the form given the journal box. Secondarily, it includes lubricating apparatus, capable of conjoint use with the box form in which. the invention primarily is found. The lubricating apparatus, so conjointly useful, is capable also of independent use.

In the accompanying drawings Fig. I is a view in vertical section and on the axial line of the car axle, through a journal box embodying my invention. Fig. II is a horizontal section in the plane indicated at ll--IL Fig. I. Fig. III is a view in transverse section, on the plane indicated at lll-IH, Fig.

Referring to Fig. I, the journal box as a whole is indicated by the numeral l, in assembled position with the axle of a car, which axle is indicated by the numeral 2. From the showing of Figs. I and III, the bearing block has, for purposes of illustration, been omitted. lt will be understood that the block is in the complete assembly interposed between the surface of the axle and the upper wall of the journal box. In Fig. I the box is shown to be open at 16. A. proper closure for this opening will of course be provided.

The journal box, as will be seen, is of the general shape now familiar, for it is desirable that it conform to the standard of the American Railway Association, and it contains the following? particular provisions. It includes, within, a false bottom 3 which slopes from the inner and outer walls of the box downwardly toward the center, where there is an opening. Between this false bottom 3 and the true bottom 4 of the box a well is formed. At the outer end of the box a pocket 5 constitutes an enlargement of the well space, and so, similarly, atv the inner end, the well is made continuous with pockets 6 which extend on either side of the axle. The car ordinarily is overturned laterally; and itrwill be understood that, given the structure described, provided witha quantity of oil less than sucient to submerge the false bottom 3, substantially all of the oil will, uponl the overturning of the car, flow into one or more of the pockets 5 and 6, 6, and be retained there. VOn restoration of the car to normal position the oil will return to the bottom of the well.

Supplementing the eEect of the sloping false bottom 3 in carrying the oil when the car is inverted, into the pockets 5 rand 6, 6, small downwardly inclined lips 11 and l2 are provided within the journal box and at the inner and outer ends of lthe box and above the false bottom 3. These lips will serve, when the car is inverted, to retain wh at small quantities of oil may be found above the false bottom, and prevent any appreciable spilling of it. The lip l2 is prolonged semi-circularly, as will be seen on comparing the'` drawings one with another, to the end that when the car is inverted, surplus oil may not dribble over the axle and be wasted, but may be carriedto and retained in the up per'part of the box.

For the purpose of carrying the oil to and distributing it upon the bearing surface of the axle 2, when the car is in normal position and running, a. distributing disk 7 'is provided. This distributing disk 7 is'rotatable in'bearing blocks 8, which are mounted in guides 9, and backed by springs 10.. The disk 7 is mounted beneath the axle with its own axis in parallelism with that of axle 2. It depends at its lower periphery into the body of oil maintained in the journal box beneath the false bottom 3, and it bears under spring tension tangentially upon the axle. As the car travels and as the axle 2 rotates, the disk 7 by its tangency upon the 'axle is caused to rotate on its own axis, and as it rotatesV it carries oil from the well into which it depends, to, and distributes it upon, the

as to transfer from the well relatively large quantities of oil to the bearing surface of the car axle. To this end the disk has a relatively broad face, and its face is grooved into shallow, rounded undulations, andthe disk is thickest at its rim.

More particularly, the face of the disk is provided with a medial crest 13 of maximum diameter, andupon this medial crest 13 the disk makes tangency upon the axle 2. From Y crest 13 the face of the disk recedes on gentle curves, and rises again to two marginal crests 14 of somewhat less, though not greatly less,

diameter. In consequence of these details of shape, when the car is moving at relatively slow speed, the oil (Which will be of relatively heavy and viscous nature) will tend to flow over the face of the disk and pass to the axle in'two streams, on either side of crest Y 13. And when speed increases, the augmented ow of oil will be chiefly centrifugal, from the two minor crests 14 directly to the axle.

'The box is preferably provided with a bottom opening, normally closed by a removable `plate 15. vUpon this plate 15 the guides 9 rest, and the bottoni opening is of suflicient size that the lubricating apparatus may be withdrawn through it. This bottom opening affords access to the interior of the box, for all purposes, icluding that of the insertion and removal of the lubricating apparatus.

The journal box of this invention is intended to be used without the usual packing of waste, and is intended to avoid and prevent fl the great losses with which railways now have to deal, consequent upon hot boxes.

In operation, the well in the bottom of the box is filled with lubricating oil (which, as has been said, is relatively heavy and viscous within its walls a false bottom which extends in the direction of the length of the axle to which the box when in service is applied, from the opposite inner and outer journal-box walls to an intermediate opening, and oilretaining pockets formed with thev journalbox walls and at the inner and outer ends of the journal box, with which pocketsthe space beneath the false bottom is at the inner andi outer ends thereof in communication.

in nature) preferably to a level nearr though somewhat below lthe level of the opening through the false bottom 3. As the car travels, the disk 7, which conveniently is journaled substantially in the opening in the false bottom,'bearing at its periphery yieldingly upon the axle 2, is rotated by theturning axle. Since it dips into the body of oil beoverturning'escape through the opening in the false bottom, flow to right or left, as the case may be, and are caught by the wings 11 and 12, and returned, whenthe ca r is righted again, to the well.
