THOMAS H. SYMlNGTON, OF BALTIMORE, MARYLAND.

RAILROAD JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 764,507, dated July 5, 1904. Application filed July 3U, 1901. Serial No. 70,300. (No model.)

To 1/.ZZ whom it may concern.-

Be it known that I, THOMAS H. SYMINGTON, a citizen of the United States of America, and a resident of Baltimore city, State of Maryland, have invented certain new and useful Im provements in Railroad J ournal-Boxes, of which the following is a specification.

My invention relates to a journal-box for car-axles of the usual round or square bottom form, which is familiarly known as the Master Oar-Builders type.

It consists of a box square at the top and round orl square at the bottom, having' an aperture in the rear through which the axle passes and a door in the front by which the waste and lubricating oil or grease may be in serted. As the journal revolves in use the oil, being' liquid or converted into liquid by the heat of the journal, falls to the bottom of the box, while the waste rolled up by the motion of the journal is packed on one side of the box and frequently drawn entirely away from the oil, so that a box will often become heated, although it contains a large quantity of oil and waste.

My invention consists in the introduction into the interior of the journal-box of two or more radial ribs which are cast integ'ral with the box and which are located at or about the lower corners of the box and which project inward toward the journal as far as the shape of the journal will permit. They are made either straight upon their edges or preferably serrated upon their edges and are parallel or approximately parallel to the axis ofthe journal, the object being to hold the waste when packed into the journal-box in contact with the journal and prevent it from rolling up on one side of the box in the direction of travel of the journal. The ribs form, with the side wall of the box, a well upon the side of the box, which will contain the oil and which when the box is packed with waste may be filled with oil and a less quantity of oil employed than would be thecase if the ribs were omitted. Furthermore, these ribs by their position in the box strengthen the box and it is possible to make the box lighter than has heretofore been possible.

In the drawings similar numerals of reference indicate similar parte throughout all lig- NPGS.

Figure 1 is a Verticaltransverse section of the box and axle, showing waste an d oil in the box. Fig. 2 is a vertical longitudinal section of the box without the journal. Fig. 3 is a horizontal longitudinal section of the box, showing the ribs in plan.

Referring te Fig. l, l is a journal-box having an opening in the rear 2, through which the axle 3 is passed. The box, as shown in this ligure, is round at the bottom 4, and on the interior at the lower corners of the box are longitudinal ribs 5 5, which extend from one end to the other of the box and are located approximately radial of the journal. (i 6 are a pair of ribs also longitudinally located on the interior of the box on each side and lying in the same horizontal plane and in a plane which is parallel to the axis of the journal and very close to the plane of the axis of the journal.

The edges of the ribs 5 5, as shown in Figs. 2 and 3, are made of a shape to conform to the contour of the axle, the bearing-surface of the axle being of smaller diameter than the head and shoulder. For this reason the ribs 5 5 are made on the edge of a shape which will conform to the shape of the axle.

As shown in Figs. 2 and 3, the portion of the ribs 5 5 which is opposite the bearingsurface of the axle is provided on its edges with a series of notches 7 7.

In practice the operation of my invention is as follows: Vhen waste is packed into the journal-box under the axle and between the ribs 5 and 6 on each side of the axle, it will `be held by those ribs and prevented from passing from one side to the other of the journal-box and rolling up wholly on one side, and it will also be held and prevented from riding up under the bearing-block, which rests upon the top of the axle, and thus the packing will be enabled to perform its function for a longer period of time and with a smaller quantity of lubricant than would be the case with any other construction. The serrated edges of the ribs 5 5 hold the vaste, which may be packed over them against the journal, and `prevents lateral motion of the waste, so that it will not IOO an angle to each other and in lines approximately radial of the journal, the space between the ribs being open, whereby packing may be inserted between the ribs and under the journal without removing the journal from the boX, said ribs forming the upper surface of a space to be packed with waste.

2. A railway journal-box oi' standard type, having a pair oi' ribs integral with said box projecting inwardly toward the journal at an angle to each other and in lines approximately radial of the journal, the ribs extending in the box beyond the end of the journal, whereby packing may be inserted under the journal and between the ribs without removing the journal from the box, the ribs being provided upon their edge with serrations and notches, said ribs forming the upper surface of a space to be packed with waste.

3. A railway journal-box of standard type, having a pair of ribs integral with said box and projecting inwardly toward the journal at an angle to each other, the space between the ribs being open whereby packing may be inserted between the ribs and under the journal without removing the journal from the box, said ribs forming the upper surface of a space to be packed with waste.

Signed by me at Baltimore, Maryland, this 25th day oi' July, 1901.
