Application February 5, 1948, Serial No. 6,372

truck without the necessity of removing the car body, thereby appreciably decreasing the time and cost of repair and lubrication of journal boxes to a minimum.

An important object of the invention is to provide a journal box which will be held in place by the weight of the rolling stock supported thereby,

eliminating the use of bolts or nuts, commonly employed in securing and adjusting journal boxes with respect to the axles.

With'the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a side elevational view of one end of a truck side frame of railway rolling stock, illustrating a journal box, constructed in accordance with the invention, as mounted thereon.

Fig. 2 is a plan view thereof, a portion of the truck frame being shown in section.

Fig. 3 is a vertical sectional view through the journal box illustrating a car axle as fitted therein taken on line 33 of Fig. 4.

Fig. 4 is a vertical sectional View taken on line 4-4 of Fig. 3.

Fig. 5 is a plan view of the journal box.

Fig. 6 is a side elevational view thereof.

Fig. '7 is an end elevational View of the journal box.

Fig. 8 is an end elevational view illustrating the journal box opening formed at one end of the side frame of a truck frame.

Fig. 9 is a sectional view taken on line 9-9 of Fig. 8.

Fig. 10 is. a vertical sectional view on line 'l0l0 of Fig. 9 with the members 5 and 9 assembled.

Referring to the drawings in detail, the reference character 5 indicates one end of a truck side frame, forming a part of railway rolling stock.

As clearly shown by Fig. 8 of the drawings, the truck side frame is formed with journal box openings which are formed with upper recesses 6 and lateral vertical grooves 1, the grooves l and recesses 6 being formed in the wall of the journal box opening.

The grooves I have one of their respective walls cut away as at 8 providing entrances to the vertical grooves I, the cut-away portions 8 extending inwardly from the outer edge of the journal box opening.

The journal box forming the subject matter of the present invention is of the roller bearing type and is adapted for use with practically any type of roller bearing now in production.

As shown, the journal box includes a substantially circular housing 9 in which the roller races II], are mounted, the roller races supporting the rollers II.

The housing 9 is somewhat smaller in diameter than the diameter of the opening in the truck frame, and has extending upwardly from the upper surface thereof, an enlargement [2 adapted to fit closely within the recess 6, the formation of the enlargement I2 being such that it will move readily into the recess 3 and be held therein by the weight of the car body, supported thereon.

Extending from opposite sides of the housing 9, are wide lugs l3 which have rounded outer edges designed to fit within the grooves 1. On positioning the journal box, it is to be understood that the truck frame will be elevated by means of a suitable jack, whereupon the lugs l3 will fall opposite to the cut-away portions 8. With the weight of the car body removed, the journal box may now be readily slid from the opening within the truck side frame. Removal of the journal box may be desirable in order to repair or replace worn parts in the bearings of the journal, or it may be necessary to repack the bearings. The journal may after repairs or repacking, be readily positioned on the axle of the rolling stock, in such a way that when the lifting jack is removed, the Weight of the car body will cause the truck frame to move downwardly, the lugs passing into the vertical grooves I, while the upper recess 6 accommodates the enlargement l2 preventing twisting of the journal box.

Having thus described the invention, what is claimed is:

In combination, a truck frame having a circular journal box opening, the wall of the journal box 0 opening having a recess formed therein adjacent REFERENCES CITED to ofgthe Journal 9 P the W The following references are of record in the of sand Jotililrnalt box opeii ng hazing1 verftlcal fil of this patent: grooves W1 cu -away por lOIlS ex en mg rom the lower ends of the grooves to the outer edge of 5 UNITED STATES PATENTS the opening, a circular journal box having lugs Number Name Date extending from the sides thereof movable in the 2 M Ord July 16, 1918 grooves and the cut-away portions, and an en- 1,343,618 0 lr June 15, 1920 largement formed on the top of the journal box, 1,636,757 e bu July 26, 1927 fitted into the recess and retaining the journal 10 2,047,243 Baahman ly 19, 1936 box in position within the journal box opening.
