To all whom it may concern 7 Be it known that 1, JOHN M. Ronnrnvo, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain, new and useful Improvement in Car-Truck Side Frames and JournallTioizes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to whichit appertains to makeand use the same, referones being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an end elevation of a car truck side frame of my improved construction and showing the housing which combines with said frame to rorm'the journal box. Fig. 2 is a vertical section taken lengthwise through the center of the journal box. Fig. 3 is a horizontal section taken through the center of the journal box. Fig. at. is a vertical section taken approximately on the line d--d of Fig. 2. Fig. 5 is a vertical section similar to Fig. 4 and showing a modified construction of the combined side frame and journal box. Fig. 6 is a horizontal section taken approximately on the line 6-43 of Fig. 5. Fig. 7 is a detail sectional viewof a further modified form of the combined side frame and journal box.

This invention relates generally to cast metal side frames for car trucks, and more particularly to the construction and arrangement'of the journal boxes positioned upon the ends of the side frames.

The primar objects of my invention are, to provide a ivided journal box whose essential parts that receive and resistthe greatest strains are constructed of a very strong and tough material and the other parts of a material of comparatively less strength; to provide a journal box having a removable lower shell or housing that is symmetrical on both sides of its longitudinal axis in order that it may be readily positioned on either end of the side frame; third, to rovide a reversible and interchangeable lin for connecting the end of the side frame with the shell or housing of the journal box and fourth to provide a constructionwherein worn or broken parts can easily and quickly be replaced.

Further objects of my invention are, to provide a simple, strong and rigid construction wherein a portion of the truck side frame and a housing or special form are combined to form the journal box, to provide a simple construction wherein the housing forming the lower port-ion of the box may be easily and quickly applied to or removed from the truck side frames to permil; the axles to be moved endwise relative to the side frames when the truck is being assembled or taken apart, and further to provide an interchangeable and reversible block or link, which, when properly posi tioned, forms a portion of one of the side walls of the journal box.

A further object of my invention is to generally improve the construction of the divided journal box shown in my Patent #856,492, dated J one 11, 1907.

To the above purposes my invention consists in certain features of novelty herein after more fully described and claimed.

Referring by numerals to the accompanying drawings, and particularly to the construction illustrated in F igs. 1 to l inclusive, 1 and 2 designate respectively the compression and tension members of a cast metal side frame, said members being united at their ends and extended a sullicient distance beyond the meeting point to form a head 3, which forms a support for the housing or shell of the journal box- The bottom flanges of the tension member 2 of the side frame extend horizontally beneath the head 3, said flanges being widened at this point to form a plate 4 which serves as a top or cover plate for the journal box. The top flange of the compression member 1 extends over the head 3 and unites with the outer end of the plate 4 to form a lug 5 which is perforated transversely in order to receive a bolt or pin utilized in attaching the upper end of the link or block, hereinafter more fully described, and which is utilized as a connection between the end of the truck frame and the housing that forms the lower portion of the journal box.

Formed integral with the plate 4 near the inner end thereof or adjacent to the point where said plate unites with the tension member 2 is a depending transversely disposed web 6 provided on its inner face with an integral lug 8 against which the side lugs of the journal bearing engage. The underside of this web is provided with a beveled face 9,.and the ends of said web are provided with beveled faces 9. Formed integral with the web 6 and with the bottom flange of the tension member 2 1s a pair of depending webs 10, the same being transversely perforated in order to receive a pin or bolt 11 utilized in attaching the inner side wall of the journal box housing to the side frame. The housing formin the lower portion of the journal box is preferably cast in a single piece and comprises a shell 12 which is substantially U-shaped in cross section, having an opening 13 in its outer end. This opening is normally closed by an ord nary journal box door (not shown) that is hinged in the usual manner upon lugs formed on top of the housing. The inner end of the shell or housing 12 is provided with an opening 14 for accommodating the endof the axle, and formed in said inner end is a vertically disposed pocket 15 adapted to receive a .suitable dust guard. The upper portion of one of the side walls of the shell or housing 12 is cut away so as to form an opening 16 of such size as to re-' ceive the web 6, and the edges of this opening are inclined or beveled to correspond with the beveled faces 9 and 9 on the bottom and front and rear ends of the web 6. Formed on top of the end portions of the shell or housing 12 are transversely disposed overhanging llps 17 which engage corre- .When the shell or housing is properly applied to the side frame one'pair of these heads occu ies a position inunediately adjacent to t e depending lugs 10 and said parts receive the pin or bolt.11. The opposite side wall of the shell or housing is cut away at its upper end to form an opening 16, equal in size to the opening 16, previously described. Thus it willbe seen that the sides of the shell or housing 12 are'symmetrical and identical in construction, and therefore said shell or housing can be readily appliedto either end of the side frame. Such construction materially reduces the first cost of parts, and likewise lessens the cost of repairs.

The interchangeable and reversible blockor link 22 is adapted to close the opening between the outer wall of the shell or housing and the endof the top plate 4, said block or link being provided on its four edges with beveled faces that engage correspondin beveled faces on'the shell or housing aroun the openings-16 or 16 and a beveled face on the underside of the head between the plate 4 and lug 5. Formed integral with this block or link on the outside thereof is a pair of verticall disposed ribs 24, the ends of which are per orated in order to receive shell or housing 12. This block or link is i made symmetrical in order that it can be interchanged and reversed in position so as to be used at either end of the side frame. Formed on the inner face of the block or link 22 is a vertically disposed stop or lug 27 against which engages the corresponding side lugs of the journal bearing. The end of the axle, the journal bearing and the journal bearing wedge are shown in dotted lines in Figs. 2 and 4. The journal bearing wedge is prevented from moving outward by the usual lugs 28 formed on the shell or housing12 at the upper end of the opening 13.

It will be noted in my improved construction that the plate 4 and web 6 form the top and a portion of the inner sidewall of the journal box, and that the block 22 which forms a ortion of the outer side wall of the journal ox, serves as a link whereby the outer portion of said journal box is connected directly to the end of the side frame. When the ends of the ribs 24 are properly connected to the lug 5 and perforated heads 21, the plate or block 22 fits snugly between the outside wall of the shell or housing 12 and the end of the plate 4, and as said block or plate 22 is forced into its seat, the beveled faces 23 engaging against the correspondin beveled faces on the shell or housing and the end of the plate 4 tend to move these parts away from one another, thereby pulling the overhanging lips into close enga ement with the ribs 18, and form a tight joint between the beveled faces 9 and 9 and the corresponding beveled faces around the edge of the opening 16. To separate the parts in order to move the axle and wheels endwise away from the truck frame, it is only necessary to remove the pins or bolts 11 and 2G and the plate or block 22 is now free to be swung upward, thereby permitting the shell or housing 12 to move outwardly away from the side frames with the axle.-

By my improved construction much time and labor is saved in the assembling or dismantling of trucks, and when the shell or housing is properly applied to the end of the side frame and the detachable plate or block is properly positioned to connect these two parts, a very strong, substantial journal box 1S formed and the joints between the assembled parts are practically oil and dusttight. The shell or housing forming the lower portion of my improved divided journal box is made symmetrical on both sides of its longitudinal axis in order that it may be applied to either end of the side frame, and likewise the block or plate 22 is made symmetrical in order that it may be reversed in position or interchanged when applied for use.

models .in 7 the outer stop lugsfor the journal bearing wedge are formed on the outer end of theplate 4, which last mentioned-plate is necessarily extended outward the proper ilh till

distance to carry said lugs. This construction necessarily requires a comparatively longer housing, or shell 12, but by said construction the proper distance required by M. C, 18. standards are maintained within the journal box and only one size of shell or housing is required for bearings of the various acce ted capacities.

It is evldent that slight changes may be resorted to in the construction and relative arrangement of the parts herein shown and described without departing from the spirit of my invention, the scope of which is set. forth in the appended claims.
