' Be itz-known that 1, JOHN A. LAMONT, a citizen ofjthe United States, and resident of Granite City, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Built-Up Side Frames, ofwhich the following is a specification. I

My invention relates to railway cars, and has particular reference to a novel built up side frame for use in connection with car trucks.

An object in the construction of the present device is to provide for economy incost of construction. This economy is the result of the use of commercial rolled sections which are fabricated to form a substantially integral side frame structure.

A further ob ect is to lessenof such structures by so disposing the metal thereof that the greatest possible resistance is secured with minimum weight. present structure the principal parts of the truss, namely, the compression and tension members, are formed from commercial of the parts being formed by casting in steel or malleable iron.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is an elevation of a portion of a car truck side frame constructed in accord ance with my invention; Fig. 2 is a plan view of the same with a portion of the compression member brokenaway; Fig. 3 is a section on theline 3-3 of Fig. 1; Fig. 4 is a section on the line 4-4 of Fig. 1; Fig. 5-

is a view similar to Fig. 1, showing a slightly modified construction; Fig. 6 is a plan view'of the construction shown in Fig. 5, with the top arch bar removed; Fig. 7 is a longitud'nal vertical section through the construction of Fig. 5, and, Fig. 8 is a see- Fig. 5.

Referring more particularly to Figs. 1 4, it will be seen that I provide a compres sion member 10, of channel form, and a ten "1011 member 11, of T-shape, both of these -embers being preferably commercial rolled .niapes. Separating the truss at the middle portion-are the columns 12, acting as struts. The ends of the casting 13, journal box 14.

'to the columns 12, by means of rivets 1i, i

the columns providing guides 15, for a bolsterv and having an enlarged portion 16,

within which a bolster having lips or side guides may be inserted. compression member abuts against a shoulder 17, formed on the casting 13, and in order to insure a rigid connection I provide side grooves or recesses 18, in the cast lng near the top thereof, the flanges 19. of the channel being bent into these recesses. as best shown in Fig. 3. The tension member 11, is fitted into a recess in the casting 1.3. v as best shown in Figs. 1 and l. The. side flange 20, of the T, is terminated at the point 21, the web of the T being bent at or about the point of termination of the flange to lie in the plane of the web of'the channel 10, as indicated at 22,

are passed through the compression and tension members and casting and serve to hold the parts rigidly together. The casting is provided with suitable pedestal jaws 21L, between which the journal box 14, is held. A brace or filler 25, extends between the converging ends of the compression and tension members and rivets 26, unite these members to the web of the compression member. In the construction of Figs. 5 and 6, the compression member 27, is of channel form but is not crimped or bent into engagement with the casting, merely abutting against a shoulder '28, formed thereon, the flanges of the channel being sheared off to lie in the plane of the top of the journal box 29, which is integral with the casting 30. The tension member 31, is of T-shape, the flange of the T, terminating at 32. Theweb 33, of the T, continues over the top of the box and terminates at the point 34. Rivets 35, extend through the two members and the box and unite the parts rigidly. The strut orcolumns' 36, cooperate with the rolled shapes, the upper portion 37, being in the form of achannel and fitting within the channel of the compression member 37. The lower portion of the casting forming the columns is slotted to accommodate the flange of the T 31, as best shown in Fig. 7. As in the construction heretofore described, I provide an integral extension or brace 38, which lies at the junction of thetop and bottom arch bars. In the form just described, the journal box Rivets I Atthe ends the referred to the use of rolled shapes that pressed shapes might be used With equal facility and that therefore I consider the terms rolled and pressed as synonymous.

' nged section,

I claim: y

1. In aside frame, the combination of top and bottom arch bars composed of rolled or pressed shapes, and a casting at the ends of said bars, said casting including downward projections acting as pedestal jaws and provided with a diagonally extending recess, the arch bar composing the tension member being bent into the plane of the bar eomposing the comp ion member at the ends of the two members and occupying the recess in said casting, the parts being rigidly united to form a substantially integral structure, substantially as described: "l

2. In a .side frame, the combinat'on of top and bottom members and a strut, said top member being in the form of a channel, said bottom member being a rolled commercial a. flange of said-bottom mem= her being terminated at the point of'jun tion with said top member, the Web of said bottom member being bent into the plane of said top member, and a casting with which said top and bottom members cotiperate and to which they are rigidly secured, substantially as described.

3. In'a side frame, the combination of top and bottom members, said top member being channel compression member and T-shaped tension member, the members being brought into engagement at their ends, and a casting hav ng an integralportion lying between said tension and compression members at a the j ncti nv of the two as described,

the combination of tension member and P int. a j ent to member ubstantial y 5, In a side frame, comp ess on me ber,

' strut, said compression member being of rolled channel Shape and saidtension mem:'

ber of rolled Tisha 113e, a casting with which said members coiiperate at their ends, said casting having a T-shaped slot within which said tension member is accommor'l'ated, and a shoulder against which said compression member abuts, said casting also being provided with a brace located adjacent to the junction-of saidtension and compression members and adapted to stiffen the same, substantially as described.
