Application filed April 5,
This invention relates to a new and improved pressed steel side frame and more particularly to a side frame having journal boxes secured thereto yby welding, in such manner as to become an integral part there- Pressed steel side frames have heretofore been made and have been secured to journal boxes in various manners, as, for example, by being bolted to a horizontal face of the frame. According to the present invention the journal box is fitted into an ope-ning in the side frame and is thus secured against movement by the surrounding portion of the side frame. It is welded to the side frame to secure it lixedly to the frame as an integral part thereof.
It is an object of the present invention to provide a side frame structure having journal boxes integrally secured thereto and enclosed by a portion of the side frame.
It is a further objectto provide a construction of this character in which the side frame is formed of a pair of members welded together and in which they journal box extends through registering openings in the two side frame members and is welded to both said members.
' @ther and further objects will appear as the description proceeds.
I have illustrated a preferred embodiment of my invention in the accompanying drawing, in which- Figure 1 is a view of one-half of a side frame constructed according to the present invention;
Figure 2 is a front view of Figure 1;
Figure 3 is a view of Figure 2 as seen from the left;
Figure 4 is a section taken on line 4-4 of Figure 2; and l I" Figure 5 is a Section taken on line 5 5 of Figure 2.
The side frame as shown comprises two pressed steel members 11 and 12, the inwardly extending flanges of which are welded together along the line 13. As shown in Figure 4, the side frame members are U-shaped in cro-ss section through some portions of their area, these U-shaped members being welded together. In such p0rtions of the side frame as shown in detail in Figure 5, which is a section of the lower tension member, the side frame members 1924. Serial No. 704,314.
are L-shaped and are only'secured together by welding on a single line.
Each side frame member 11 and 12 has at each end an opening formed therein, the opening being surrounded by an inturned flange 14. As shown in Figure 3 these flanges 14 and 15 abut on the line 13 and are welded together. These flanges are formed by drawing down the metal from the interior of the opening surrounded by the flange. Y
The lower flanges 11 and 12 shown welded together in Figure 5, are welded to the flanges 14 and 15 at 16 as indicated in Figure 2, to stiften the construction. The
journal boxes 17 which are preferably formed of pressed steel are fitte'd into the opening encircled by the flanges 14 and 15. These journal boxes extend through upon both sides of the side frame and are welded to both of the members 11 and 12. They thus aid in strengthening the connection between the two members and adding to the rigidity of the construction.
These journal boxes, as shown in Figure 3, have the hinge member 18 welded thereto and also the member 19 welded inside the box, this member serving to maintain the usual dust guard in position.
I have shown one preferred form of my invention by way of illustration but it is to be understood that I contemplate such changes and modifications to meet varying conditions as are within the spirit and scope of the Vappended claims.
I claim:
1. Side frame construction comprising a side frame formed of pressed steel, an opening formed in the frame surrounded by a transversely extending flange, and a journal box fitted into the opening.
` 2. Side frame construction comprising a pair of pressed steel side frame members having inwardly extending flanges welded together, registering openings formed in the members, and a journal box extending through said openings and welded to the members.
3. Side frame construction comprising a pair of pressedfsteel side frame members having inwardly extending flanges welded togetherI registering openings formed in the members surrounded by inwardly extending flanges, and a pressed steel journal box fitted in said reistering openings and bearing against the anges.
el. Side frame construction comprising u pair of pressed steel side frame members having inwardly extending anges Welded together, registering openings formed in the members surrounded by inwardly extending anges, and a pressed steel journal bof; Fitted in said registering openings and bearing against the lizinges, said journal bonY being Welded to both suid frame members.
Signed at St. Louis7 Missouri, this Qnd day of April, 1924.
