RAILWAY SIDE FRAME.

Specification of Letters Patent.

Patented A112. 31. 1920.

Application filed October 28, 1919. Serial No. 333,903

To all whom it may concern:

Be it known that I, CLAUS J. WERNER CLASEN, a citizen of the United States, residing in the city of Davenport, county of Scott, and State of Iowa, have invented certain new and useful Improvements in Rail- Way Side Frames, of which the following is a specification.

My invention relates to side frames for car trucks and has as its principal object the provision of an improved side frame of the integral journal box type which shall possess the characteristics of increased strength and durability combined with economy of manufacture.

The novel features of my invention are pointed outwith particularity in the appended claims. The invention itself, however, With further objects and advantages, will best be understood from the following description taken in connection with the accompazaying drawing in which Figure 1 is a top plan view of a side frame according to my invention;

Fig. 2 is an elevational view of the side frame illustrated in Fig. 1, part being broken awa F 1g. 3 is a transverse sectional view of the frame shown in Figs. 1 and 2, taken on the line 33 of Fig. 1;

Fig. 4 is a section on the line 44 of ig. 5 is a section on the line 5-5 of F ig 2; F ig. 6 is a section on the line 6-6 of ig. 7 is a section on the line 7-7 of Fi 2' I Fig. 8 is a section on the line 8-8 of Fig. 2; I

ig. 9 is a section on the line 9-9 of Fig. 10 is a section on the line 10-10 of Fig. 2.

he side frame illustrated in Figs. 1 to 10 inclusive comprises longitudinally extending top and bottom members or chords 1 and 2 respectively and two columns or struts, such as 4, extending between members 1 and 2.

The top member 1 is connected to the bottom member 2 at points near the ends of the frame. Struts 4 divide the space between members 1 and 2 into three apertures, the central one of which is roughly quadrilatnel shaped or U-shaped in cross section throughout most of their lengths, the central webs of these members being on top in the case of member 1 and at the bottom in the case of member 2. Struts 4 are integral with members 1 and 2 and are also channelshaped or U-shaped in cross section, the central plates or Web of these struts being on the sides toward the said central aperture,

I provide outwardly-extending beads, such as 5, around the edges of said triangular apertures, said beads being widened outwardly in sectors near the lower ends of struts 4 to form flanges such as 6. The outwardly-extending flanges 6 serve to reinforce the frame at the angles formed be tween struts 4 and chord 2.

Between the struts 4, the chord 2 has an upper central or horizontal web 8, and in this sector the chord 2 has also outstanding flanges, such as 9, at each side thereof in the same plane as web 8, forming therewith a spring seat 10 in which is an aperture 11 for interlocking the spring plank, not shown, with the side frame. It is evident that in the sector between the struts 4, except at aperture 11, chord 2 is of box section.

The top member 1 extends somewhat beyond the points of junction between itself and the bottom member 2, and in the angle thus formed I provide journal boxes, such as 12, which are integral with members 1 and 2, the central webs of chords 2 merging into the side walls of the boxes as illustrated in Fig. 4. The top member 1 extends across the tops of the journal boxes 12, the depending flanges of member 1 being integral with the tops of the boxes. Member 1 1s preferably open at both ends as appears at 1 13 to permit the ready removal of cores.

boxes is of great strength, especially when the up er 0 0rd member extends over the tops 0 the journal boxes, thus formin an integral box section therewith. It wil be seen also that the pro'ecting flanges 6 increase the stren h of tl ie entire frame without materially increasing its weight, while the box section at the spring seat also reinforces the entire structure.

Having thus described my invention, I claim:

1, An integral metallic side frame for car trucks, comprising column members, a top member, a lower member, and a journal box at each end of said lower member, said column, top and bottom members being all of U section, said top member extending above the tops of said journal boxes.

2. An integral metallic side frame for car trucks comprising column members, a top member, a lower member, and a jour nal box at each end of said lower member, said column, top and bottom members being all of U section, said top member extending above the tops of said journal boxes and forming a box-like structure therewith.

3. An integral metallic side frame for car trucks comprising column members, a top member, a lower member, and a journal box at each end of said lower member, said column, top and lower members being of U cross section, said lower member comprising a spring seat which closes the U between said columns, said top member extending above the tops of said journal boxes.

4. An integral metallic side frame for car trucks comprising columns, a top member, a lower member, and a journal box at each end of said lower member, said column, top and lower members being of U cross section, the said lower member comprising a spring seat designed to interlock the spring plank with the side frame, said to member extending above the to s of said journal boxes.

5. An integral si e frame for car trucks comprising columns, a top member, a lower member, a journal box at each end of said lower member, and brake beam hanger brackets attached to the back of the frame, said column, top and bottom members being all of U section, said top member extending above the tops of said journal boxes.

6. An integral metallic side frame for car trucks comprising columns, a top member, a lower member, and a journal box at each end of said lower member, said column, top and bottom members all being of U section, said column members being spaced to form a bolster opening, the free edges of the U shaped members bounding, on each side of the central bolster openlng, an opening of substantiall triangular shape, said top member exten ing above the tops of said journal boxes.

7. An integral metallic side frame for car trucks comprising columns, a top member, a lower member, and a journal box at each end of said lower member, said column, top and lower members being of U section, said U shaped column and lower members having flanges extending out wardly from their free edges at their points of juncture.

8. An integral metallic side frame for car trucks comprising columns, a top member, a lower member and a journal box at each end of said lower member, said column, top and bottom members being of U section, said column-members being spaced apart to form a central bolster opening and having their central webs bounding said opening, said top member extending above the tops of said journal boxes.
