This invention relates to journal boxes and axles for mine cars and similar cars in which the track wheels surround the axle between the bearings which support the car body. The bearing is of the self-aligning type. p V

The object of the invention is to provide a structure which allows economical manufacture and easy assembling and separation of the parts and provides good control of end thrust and also provides good lubrication.

JOURNAL-BOX AND AXLE 1927. Serial No. 186,959.

B adapted to bear against the outer transverse face of the flange, A

The hub has a flange, B extending in- HUGH W. SANFORD AND HARRY V]. JQNES, OF KNOXVILLE, TENNESSEE, ASSIGNORS ward over and beyond the flange, A The hub flange has a lateral extension, 13*, on which is an inner face, B far enough from the axle to receive a key, B, between the axle and the face, A On the key is a pin or stud, B extending outward radially to,

the axle into the socket, B formed in the extension, 3*, of the flange, B It will be observed that whenthis key is in position,

it will bear on the face, Aflformed by cutting away the flange, A and thus hold the hub from turning on the axle, whereby the wheel is made fast on the journal. WVhen .this key and pin are absent, the wheel is loosefree to turn on the journal. When the key and pin are in position and the,

journal is free from the axle box and pedestal, the wheel maybe moved outward on the journal, the key sliding on the face, A and on the journal. hen the wheel has been removed'from the ournal, the key and pin may be removed from the hub. Then the Wheel may be returned to its position to be loose. This provision for rendering the wheel fast or loose is made because some operators of cars having the bearings distinct from the wheels prefer to have one wheel free to turn on the axle, particularly when the tracks on which the cars are used have curves' Then while traversing curves the wheels may turn independently of each other.

The part of the journal which extends outward beyond the wheel hub is surrounded by the bearing box, C. This box has anend Wall, O extending over the end of the journ'al. The inner end of said box is closed by a cap, G which surrounds the journal and also the adjacent end of the hub, B The cap has at each side of the structure a lateral ear, G which bears against a similar ear, C seated on the body of the bearing box. A bolt, C extends through the ears to bind them firmly to each other. The interior of the body of the box, C, is cylindrical. The cap, G has an annular shoulder, C, extending into the body of the box, C, and bearing V the journal and the end of the against the inner face of said box. The engagement thus made tends to prevent the cap from moving transversely 011 the end of the body of the box, C. The interior of the 'box is faced with a steel lining, C Beferential groove, D A ring, D surrounds the journal, A within those grooves. As will appear further on, this ring serves to keep the rollers within the bearing box when the box is removed from the journal. I

Opposite the end of the journal, the wall, C is provided with a recess, C in order that end thrust can be taken by the washers, E,

' and the cap, C

In the lowerpart of the bearing box is a reservoir, C, formed by chambering the lower half of the wall of the box. Two ports, C afford communication between the reservoir and the interior of the box. A port, C allows passing of lubricant from the reservoir through the cap, C An annular upri ht flange, C forms a part of the cap and extends close to the hub, B therebeing a space between said flange and the main wall of the cap. A horizontal annular flange, C ,,also surrounds the hub, but this'fiange is spaced from the hub far enough to receive between that flange and the hub two metal washers, E and a felt or similar packing washer, E between the washers, E Four cotters, E extend through the flange, C back of the washers, E and E and hold said washers against the flange, C Said washers, particularly the felt washer, El, are made to fit to the hub sufficiently close to prevent the passing of 4 oil or dust.

In the space enclosed by the flange, C and the end of the hub and the main wall of the cap are two larger washers, E, which are thinner than the space between the end of the hub and the cap wall and are loose on the journal, so that said washers are free to turn on the journal by the occasional frictional engagement between the washers and hub. These washers are free from each other. Hence each may rotate independently of the other.

'Each washer, E, has a radial wing, E

(Fig.4.)

In the upper part of the Wall, C of the axle box a port, F, in which is seated a removable closing member, E, which may be a grease screw in which is a spring-controlled .ball valve of welhknown form.

The interior of the hub is provided with between the flange, C

'B, outward on a channel, B extending entirely around the hub to form a lubricant reservoir. A horizontal groove, B", is formed in the interior face of the hub from the reservoir, B to the outer end of the hub and the washers, E.

Lubricant introduced through the port, F, is received into the space bet-weenthe end of the journal, A and the adjacent part of the wall, C Thence the lubricant moves by gravity into the space between the rollers, D, and along the length of the rollers, and some of the lubricant is then carried with the rollers in their movement around the journal. Some of the lubricant passes downward through the port, C into the reservoir, C and thence through the port,

'C to the washers, E, and into the space and the main wall of the cap, C. Itis preferable to introduce enough lubricant to cause the filling of all or the greater part of the reservoir, C". This will effect immersing the lower rollers, D, in the lubricant and will cause the lubricant to rise along the washers, E, to the height of the lower part of the journalfand thence through the groove, B", into the reservoir, B of the hub. The washers, E and E are intended to substantially prevent the escaping of oil between the cap and the hub. The rotation of the washers, E, in unison or independently of each other will cause those washers to carry oil upward and distribute the oil over all the faces of said washers. This action is aided by the wings, E Thus these washerswill be subjected to a minimin of friction through contact with each other and with the end of the hub and with the adjacent face of the main wall ofthe cap. When there is end thrust tending to move the journal, A, and the wheel, the car body the hub, B, will press the large washers, lb, against the main wall of the cap. Under that condition, lubrication of the faces of the washers, E, is needed to reduce friction between the 'meeting faces of the washers and between the right hand washer and the main wall of the cap and between the left hand washer and the end of the hub.

ner by bolts extending through thebolt holes, From the plate, G arms, G extend downward at each side of the axle box in position to bear against the side of the axle box and against the cars, C To increase the contact between these arms and the axle box, each side of the axle box is provided with an upright bearing face, C The ears serve as abutments for the pedestal arms.

Below said faces, C, the arms are turned laterally away from each other and each is provided with an aperture, C, which receive the ends of a stirrup red, C. Each end of said rod extends through the adjacent aperture and receives a nut, C The stirrup rod, C is spaced far enough from the lower face of the axle box to allow downward movement of the axle box or upward movement of the pedestal when the car is passing over irregularities in the rail track. During movement of the car, the pedestal may rock on the summit of the upper face of the axle box for maintaining the alignment of the axle box and the axle and the rollers, D, in the manner already known in this art.

It has already been stated that thrust by movement of the axle box toward the wheel hub is taken by the cap, C and the end of the hub and the washers, E. other direction is taken by the arms, G, and the axle box ears,

lVhen it is desired to remove the axle box, the stirrup rod, C is removed from the pedestal arms, G Then that part of the car body is raised until the pedestal arms are above the ears, C and C. When that has been done, the axle box is free to be drawn outward along and off from the journal. If the wheel is to be removed, that part of the car is to be raised sufliciently to allow the wheel and axle box to clear the pedestal arms.

The metal washers, E and the packing washer, E may be inserted and removed when the cotters, E, have been removed.

The washers, E, are to be inserted and removed through the flanges, C and G, the wings, E, of said washers passing through the notches, C, in the flange, C (Figs. 2 and 13.)
