Patented Dec. a, 1917.

Application filed June 19, 1916. Serial No. 104,569.

To all whom it may concern:

' Be it known that I, JOHN W. GURRAN, a citizen of the United States, residing at Newport, in the county of Campbell and State of Kentucky, have invented a new and useful Oil-Circulating Journal-Box, of which. the following is a specification.

The present invention relates to journal boxes, and has particular reference to an improved construction of that type of jour nal box which is used on freight and passenger equipment cars, the improvements being designed to strengthen the journal box, and to more efliciently lubricate the journals mounted therein.

An object of this invention is to provide a journal box, which meets all of the re quirements of the Master Car Builders Association rules, and which at the same time is provided with novel means for effecting a constant circulation of the oil, when the ournal is in motion, and which will prevent the excessive waste of the oil which occurs by the use of all prior ournal boxes.

This invention also aims at the provision of means, in a journal box construction, which will hold the waste from rolling or shifting, and jamming against the side of the journal box, and prevent the waste from wiping off the oil from the journal, which would create undue friction and cause undue heating of the journal and the parts bearing against the same.

A further object of the present invention is to provide a passage or chamber in the bottom of the journal box, through which the oil may freely flow as it is returned from the journal, and which is not separated from the waste by a perforated wall, or the like, but which is closed at one side by the waste only, the waste freely absorbing the oil, and there being no openings to become clogged, nor inaccessible pockets to catch grit and dirt.

A still further object of this invention is to improve journal boxes to accomplish the above outlined results, without placing any loose or separate parts in the box. The in vention is embodied in a construction which is integral and cast with the journal box; which adds but little weight to the box, and which incurs but slight increased cost in the manufacture of the box.

The present invention also provides a journal box, for passenger equipment cars, or where the journal box is mounted in a pedestal, which is of such construction that the bearing surface between the journal box and the pedestal is increased substantially one hundred per cent. This feature of the invention doubly increases the life of the journal box, and the life of the pedestal; prevents the wearing of shoulders on the pedestal and prevents the tilting of the journal box, such conditions resulting in the jarring of the passenger equipment cars when in transit; and prevents the breaking down of the journal box, which latter is a factor of danger;

Other objects and advantages ofthis invention, which are of more or less importance than the above, will be fully brought out in the following specific disclosure of the present preferred embodiment, the same being illustrated in the accompanying drawings, wherein:

Figure '1 1s a slde elevation of a journal box for passenger equipment cars, showing the improved lateral bearing surface for contact with the pedestal.

Fig. 2 is a top plan view of the same.

Fig. 3 is a longitudinal central section through the journal box with a journal mounted therein, and showing the improved interior construction of the box.

Fig. 4 is a horizontal section through the same on the line 44 of Fig. 3.

Fig. 5 is a transverse section through the journal box on the line 5-5 of Fig. 3, showing the journal packing in position.

Fig. 6 is a sectional perspective view, taken through the box looking down into the bottom thereof, and showing the location of the bottom and transverse flanges and the inclined partition wall.

ieferring to these drawings, wherein like parts are designated by similar numerals of reference throughout the several views, 10 designates an integral journal box casting of the usual approved construction and design, as shown in Figs. 1 and 2. As shown in Figs. 3, 1 and 5, this journal box 10 has, at its rear end, the usual transversely extending dust guard chamber 11; a suitable dust guard 12 in the chamber 11, and which is mounted in the usual manner on the dust guard bearing 13 of the axle 14, the latter having a ournal 15 projecting into the rear end of the journal box 10, and provided on its extremity with the usual axle collar 16; has the usual journal bearing 17 against which the journal 15. bears; has the usual .journal bearing key 18 to support the'bearing 17 and has a cover 19 hinged in the usual manner upon the forward end of the journal box to close the same.

The present invention provides certain additions to the integral construction of the journal box 10, which strengthen the bearing surfaces of the box at its points of engagement with the usual supporting pedes- .tal, which retain the oil in the box, and which effect the complete and continuous circulation of the oil when the journal 15 is in motion. As shown in Figs. 8 to 6 of the drawings, the journal box 10 is provided in each side with a horizontal bottom flange or' wall 20. The flange or wall 20 is integral with the adjacent wall or side of the box 10, and preferably tapers in thickness from the side of'the box to its longitudinal free edge. The flanges 20 are located but a short distance above the bottom 21 of the journal box, to provide a relatively small oil receiving channel or chamber along the side of the journal box beneath the flanges 20. Y

The flanges 20 pro ect inwardly from the opposite sides ofthe journal box throughout a greater portion of the length of the same, being merged with the outer curved wall of the box, and have upper inwardly sloping faces. The said channels or chambers for the oil beneath the flanges are open along their inner adjacent opposite sides throughout the entire length of the box, so that the oil is permitted to flow freely from beneaththe flanges 20 over the bottom of the box.

The inner ends of the flanges 20 connect with an upwardly extending andrearwardly inclind inner partition wall 22. This partitition wall 22 extends substantially half way up within the journal box 10, and is inclined sufficiently to provide a relatively large space between the lower end of the same and the dust guard 12. This partition wall 22 is provided with a curved recess in its upper edge to fit the journal 15, and in which the journal turns.

The partition wall 22 has, at its lower end, a horizontal forwardly projecting flange 23, which extends transversely across the rear end of the journal box 10 in the plane of the flanges 20, and which merges into and connects with the inner ends of the same. This transverse flange 23, like the flanges 20, tapers toward its free edge, and provides an inclined upper face adapted to direct oil, falling on the flange, into the central portion of the journal box. 7

A slot or passage 21 is formed through the transverse flange 23, and through the lower end ofthe partition wall 22, to permit the free flow of oil from behind the wa l 22 forwardly into the journal box. The bottom 21 of the journal box has, at its rear end between the dust guard 12 and the wall 22,

a transversely extending oil well 25, formed preferably by the depression of the bottom 21 at that point, to receive and collect oil which is thrown ofl from or dropped by the journal. The upper edge of the partition wall 22 is spaced from the dust guard 12 to provide therebetween a passage suflicient only to permit the oil to pass down into the well 25 from the journal 15.

From Fig. 5, it will be noted that the usual journal packing 26 is compressed or jammed into the lower part of the journal box 10, and is wedged or forced down between, and slightly beneath, the free edges of the flanges 20, to bind and hold the packing 26 in the bottom of the box. The packing 26 forms opposite lateral walls along the inner opposite sides of the lateral oil channels to confine the bulk of the oil beneath the flanges 20, and to permit the free absorption of the oil by the packing or waste through the entire length of the box, without the passage of the oil through perforated walls, or the like, which frequently become clogged. The bottom flanges 20 are spaced above the bottom 21 a suflicient distance only to permit the wedging of the packing 21 beneath the free edges of the flanges. It will be noted that the width of the flanges is greated than their distance from the floor or bottom of the box and that the flanges are closer to the bottom of the box than they are to the journal. This arrangement of the flanges prevents the packing from extending too far beneath the same, and provides for an uninterrupted oil passage in each side of the journal box extending from end to end thereof.

The wedging of the packing between the flanges 20 insures the retention of the packing in the central portion of. the journal box, and prevents the packing from becoming jammed against the side of the box, in which position it bears with undue friction against the journal 15, and wipes oil' all of the oil from the same. lVith the journal boxes having no means for holding the packing in place, the journal bearings and the journals themselves become heated to an excessive degree.

The journal box 10 has the usual external vertically extending ribs 27. a rrangrd near the opposite ends, and at the opposite sides of the box 10, for reinforcing the latter.

A feature of this invention is to provide bearing blocks 29, which may be cast integral with the box, and which are disposed on opposite sides of the box and n'iidway between the end ribs 27, and are of substantially the same width and thickness as the intermediate bearing ribs usually employed. These blocks 29 increase the bearing sun faces over one hundred per cent. at the op posite sides of the journal box, and prefer ably extend, as shown to ad Vantage in 1, from the bottom of the box to a point substantially two-thirds the height of the journal box.

Vertical ribs 28 extend upwardly from the upper end, and from the opposite edges of the bearing blocks 29, the ribs 28 being spaced apart, and the intervening upper edge of the blocks 29 being beveled outwardly, as at 80, to prevent accumulations of dirt, moisture, and the like, which would tend to grind and injure the bearing faces.

l/Vhen the journal box is mounted in a pedestal, of the approved and well known construction, the blocks 29, at the opposite sides of the journal box, present broad flat bearing faces for contact with the transversely extending reinforcing webs of the pedestal, so that the usual grooving and weakening of these webs cannot take place, as is the result with the use of the spaced apart vertical ribs now usually formed at the opposite sides of the journal box. The journal box usually has about one and onehalf inches vertical play in the pedestal, and the blocks 29 are made of suflicient height to provide ample bearing surfaces for the journal box against the pedestal at all positions of the journal box. As the webs of the pedestal, and the blocks 29 of the journal box, have relatively broad faces lying in contact throughout practically their entire extents, the lives of the pedestal and the journal box are considerably prolonged, on account of the wide distribution of frictional contact or pressure which is had between the journal box and the pedestal.

In operation, when the journal 15 is rotated, its frictional cbntact with the hearing 17 heats the ournal, and the heat of the journal increases the capillary action of the oil in the waste. The oil is thus fed up nardly against the journal from the bottom of the journal box.

The more friction between the journal 15 and its bearing 17, the more heat is pro duced, and consequently the more rapid is the absorption of the oil by the waste, as the latter feeds the oil upwardly against the journal. The oil which tends to pass out of the rear end of the journal box is thrown off from the inner end of the journal against, and into the passage behind the wall 22, and is deposited in the oil well 25. Oil flows forwardly from the well 25 into the lateral channels beneath flanges 20, and from there it is absorbed by the packing 26 and carried upwardly against the face of the ournal 15.

The oil which drips upon the upper face of the inclined partition Wall 22 is deflected downwardly over the wall, through the slot 24, or over the flange 23 into the bottom of the journal box.

It will thus be observed that there is a free circulation of oil, and that there are no perforated walls, screens, or the like, to impede the flowing of the oil. The well 25 is depressed in the bottom 21 of the journal box to not only retain a quantity of oil in the well, but also to catch sediment and any foreign substance which may be found in the oil.

These flanges 20, and the partition wall 22, provide ample space for a quantity of oil, and prevent the forcing out of the oil from the box when the waste, or journal packing, is squeezed into the box in the usual manner. When the waste is forced into the journal box, the oil is forced to the top, and instead of flowing out of the inner or back end of the box onto the ground, runs into the space between the partition 22 and the dust guard 12, and circulates through the lateral channels, and is absorbed by the waste.

The oil chamber, between the partition 22 and the dust guard 12, will also contain air, which will assist in maintaining the oil, and surrounding parts of the journal box, from overheating. The partition wall 22 confines the packing in the journal box, and holds it out of the oil chamber.

The increased bearing surfaces at the op )osite sides of the journal box 10 materially increase the life of the box, and the life of the pedestal in which the box may be mounted, and effect the smooth riding of the passenger equipment cars.
