CAR-UNDERFRAME Specification of Letters Patent.

Application filed February 3, 1908. Serial No. 414,007.

To all whom it mayconcern:

' Be it known that we, VICTOR M. SUMMA and JAMES T. ST. CLAIR, both citizens of the g United States, residing at St. Louis, Missouri, 5 have invented a certain newand-useful Imrovement in Car-Underframes, of which the ollowing is a full, clear, and exact description, such as will'enable others skilled in the art to which it appertains to make and use 10 the same, reference being had to the accom- I 1panying drawings, forming part of this specication, in which Figure 1 is atop 1 plan View, partly inv sec-- tion, of a car unde rame constructed in accordance with our invention; Fig. 2 is a longitudinal sectional view of the underframe, showing the center sill in side elevation; and Fig. 3 is a cross sectional view of the underframe, the righthand; half of said ,20 figure being'taken adjacent the bolster and having a center sill constructed in accordance I-.'W1th our mvention but it 'will, of course, be understood that our improved sill could begus'ed as the side sill of an under-frame instead of as a center sill.

Referring to the drawings which illustrate the preferred form of our invention, 1 designates the com ressionmember of our improved sill wh1ch referably consists of a channel that exten' s from bolster to bolster 40 of the underframe, said channel being arranged with its side flanges or legs projecting downwardly, as shown in Fig; 3. The tension member of the sill also consists of a channel iron 2 arranged with its side legs or'flanges projecting downwardly an'd'extending from olster to bolster, said tension member lying in the same vertical plane as the com ression member. Struts are interposed etween said compression and tension members to produce a long deep fgirder, said struts consisting of a number 0 pairs of vertically disposed members 3, preferably angles, that are arranged outside of the side flanges of the.

tension and compression members 1. and 2 with one leg or flange projecting laterally therefrom.

Pairs of oppositely incline-d diagonal struts 4 are arranged between the vertical stints 3 and are connected at their opposite ends to gusset plates 1 and 2* secured to the side flanges or legs of the compression and tension members 1 and 2, respectively, the lower ends of the vertical struts 3 also being connected to the gusset lates 2 on the tension" member. Some of t e vertical struts 3 are. connected at their up er ends to separate gusset plates-1 secure to the side flan es of the compression member, as shown in ig. 2, and the other vertical struts are connected at their upper ends to straps 1 which pass over the compression member 1 of the center sill, as shown in Fig. 3.- The inclined struts 4 can either be formed from commercially herein shown com rising both angles and flat bars. Preferah are secured to the webs of the compression and tension members throughout a ortion of their length to strengthen same. longitudinal sill of this construction is strong and light and can be manufactured at a low cost so that itforms a very efficient center sill.

for the unde'rframe of s -car.

The bolsters of thennderframe each consists of a pair of parallel channels Glarranged with theirhorizontal legs projectingin 'opposite directions and extending from side sill. to side sill of the underframe, the side sills 7 also consisting of channels arranged with their horizontal legs projecting outwardly, as showninFigf3.

Hexagonal to and bottomrover plates'S are secured to t e horizontal flan es of the being connected together at the ends of the sill by web plates 9. The outer end of each ly,- reinforcing plates 5 rolled, angles or-flat bars, the construction bolster channels '6 and the ends of t e trussed.

etween the horizontal legs on tension and compression members 1 and 2 of the web plates 9 is provided with an inte--- gral flange 9, as shown in Fig. 1, that is secured to the web of the adjacent bolster chan- 1 nel and the connection between the. center sill and bolster isfurther strengthened by means of angle-shaped members 10 connected to the web of the bolster channel and to the inside faces of the web plates 9, as shown in Fig. 1 and also by means of short pieces 11 of angle iron secured tothe outside faces of .the web plates 9 and to. the bottom cover plate'8 of the bolster, as' shown in Fig. 2.

The draft sills 12 consist of channels that are connected to the channel-shaped end sill 13 and to the bolster, and diagonal braces 14 are arranged between the bolster and end sill, as shown in Fig. 1 The cross-bearers of the underframe consist of deep channels 15 and comparatively shallow channels 16 connected at their opposite ends to the side' sills and also secured to the laterallyprojecting fiielnges of the vertical struts 3 of the center S Having thus described our invention, what we claim as new and desire .to secure by Letters'Patent is:

1. A longitudinal sill for a car underf rame, consisting 'of channel-shaped tension and compression members havmg their webs arranged horizontall and struts interposed between saidmem ers; substantially as described.
