JOURN AL-B OX ASSEMBLY.

Application filed August 6, 1923. Serial No. 655,864.

To all whom it may concern:

Be it known that I, MARION W. HOL- LINGSWORTH, residing at Terre Haute, in the county of Vigo and State of Indiana, and being a citizen of the United States, have invented certain new and useful Improvements in a Journal-Box Assembly, of which the following is a full, clear, and exact descri tion, such as will enable others skilled in t e art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention,

though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is an elevational side view of a preferred embodiment of my invention showing a journal box applied to a car sill at the outer side of the car wheel;

Figure 2 is a plan view of the car part to which the journal box assembly is applied;

Figure 3 is an end view of'the assembly;

Figure 4 is a vertical sectional view taken on line H of Figure 1 looking in the direction indicated by the arrows; and

Figures 5, 6, 7 and 8 are respectively similar to Figures 1, 2, 3 and 4 but showing the wheels outside of the journal box assembly and car part; and

Figure 9 is a vertical section taken on line 9-9 of Figure 7 looking in the direction indicated by the arrows and showing'the roller cage in position within the journal box and relative position of the oil reservoir.

My invention relates to that class of journal box assemblies particularly adapted for use on industrial and like cars operated under severe service conditions and exposed to the unequal stress of travel over stretches of uneven track or sharp curves.

The principal object of my invention is to provide a ournal box so assembled with the car as to minimize the 'ar of service upon the journals and axles oused Within the box.

Another and important object is to provide means associated with the box and car for absorbing the shocks of impact or sudden pulling strains.

In the drawings, 10 is a side sill of a car until its inertia is overcome, the box also rocking in a reverse direction during buffing operations when the axles tend to surge forward after the car body will have been checked in its forward movement. This surge and lag of the axles will set up a vibrating movement of the respective boxes under service operations and is ieidingly absorbed by the journal box assembly resiliently applied as hereinafter described.

The journal box is fitted with a-plurality of dowels 14; rising from its upper arcuate face 12 and 1preferably arranged. in the axial center of tie box. These dowels are received in recesses 15 in the underside 16 of the car side sill l0 and are there held in interlocking engagement by means of a plurality of vertically arranged box guiding bolts 17 rigidly held within the sill 10. As best shown in Figures 1 and 2, these bolts are arranged at opposite. sides of the dowels and enter openings 18 in opposite ends of the journal box 11. The bolts 17 are preferably fitted with nuts 19 let into pockets 20 in the underside of the sill 10 and with nuts 21- at their ends at the upper side of the sill thus holding the bolts rigidly against longitudinal displacement caused by the vibrating movements of the journal box at the bolt lines.

The journal box bolt openings 18 are shaped to provide bell-mouthed or flared portions 22 at their ends to prevent possible interference with free journal box movement at the bolt positions. The journal box is further provided at the bolt openings 18 with embossments 23 surrounding the lower ends of said openings and forming spring abutments for springs 24 surrounding the lower ends of the guiding bolts 17. The springs are supported by the nuts 25 adapted to adjust the springs to any desired degree of compression.

To prevent undue wear of the side sills 10, the underside thereof is protected against the action of the rocking journal box by a wear plate 26 and provided on its upper face with a tie plate 27, both .plates perforated to receive securing bolts 28 connecting them to each other and to the sill. The bottom wear plate 26 is perforated to receive dowels 1% of the journal box 11, both plates being also perforated to receive the guide bolts 17, said perforations in the bottom plate being large enough to permit the passage of the shoulder nuts 19 and their respective washers to facilitate removal of the bolts 17 without disturbing wear plate 26. Y

he body of the box 11 at the axle line is circular in transverse cross-section being designed to receive a roller bearing assembly comprising a roller cage 30 abutting a shoulder 31 at the inner end of the jour1 at box and 'itliciently greater in diameter than the axle 13 to provide a space between them toiaccommodate a set of rollers 32, the asscmblv being held from displacement by caps 33 also designed to provide an oil reservoir 234 for lubricating the roller assembly. lhe box caps are held in position by a number of screws 35 tapped into the journal box as shown in Figure 4. A suitable oil plug 36 is provided in the cap 33 to permit charg ing of the oil reservoir 34.

A modification of the assembly of Figures 1 to 4, inclusive, is shown in the remaining figures of the drawings. In this modification, the car wheel 9 is outside of the side sill 10 instead of between the sills as in the preferred embodiment. Such relative disposition of wheel and journal box would require a slight change in the construction of the journal box to permit ready lubrication of the roller assembly. Figure 8, showing a vertical section taken on line 8-8 of Figure 5, looking in the direction indicated by the arrows, illustrates a box 41 formed with an oil well portion 37 providing a reservoir for the oil which ultimately reaches the rollers 38 through oil ports 39 in the roller cage 40. The oil is introduced to the reservoir through openings 41 closed by plugs 42 at opposite sides of the box as best shown in Figure 9. The box thus modified is open at both ends to receive axle 43 which extends outwardly beyond the box and respective wheel 9 and is fitted with a wheel retaining collar 44: held in position by a pin 45.

In both forms of the invention the car sill is supported upon the journal box at a fixed height above the axial center of the box when the car is at rest, but upon movement of the car body under draft or impact the dowels 1.4 will be moved to one side of a vertical plane through the center of the axle and cause the box to rock on its axis and compress one of the springs 24 at the side of the box. The expansive power of the compressed spring will yieldingly resist further tilting of the box and react to return the box to its upright position. If the curved face 12 of the. box is struck from a point on the axial line below the center of rotation of the box as shown in the drawings, the car body will be raised upon tilting movement of the journal box, whereupon gravity will operate to cause the car body to return to its normal position of rest above the axle, thereby supplementing the spring in restoring the box to its upright position.

From the foregoing it will be noted that there has been provided a journal box assembly which automatically restores the journal box to its normal balanced position at the center line of the axle and Wheel, and one in which the boxes are held against permanent displacement relatively to the sill. It will also be noted that the top and

bottom plates

27 and 26 respectively, when connected in the manner above described, operate as a unit to prevent disruption of the assembly parts.
