ence being had to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of one end of my improved underframing. Fig. 2 is a vertical sectional view of the same partly in side elevation. Fig. 3 is a sectional view on line 3-'3 of Fig. 1. Fig. 4 is a sectional view on line 4.-4 of Fig. 1. Fig. is a sectional view on line 5 5 of Fig. l.- Fig. 6 is a sectional view on line 6 6 of Fig. 1. Fig. 7 is a sectional view on line 7"-7 of Fig. 1. Fig. 8 is a sectional view showing a modified form of connection.'

This invention relates to a new and useful improvement in underframes for cars; the object being to construct an underframe in which the tension and compression members of the several load-carrying elements are in tegral with vertical juxtaposed webs, the latter being connected together by means of suitable fastening devices.

By making the underframes inthe mani ner above described, it is possible to cast the top and'bottom sections without the use of core boxes.

While I have shown my improvement as applicable to an underframe in which the load-bearing members are made up of sections, it is obvious that the division lines between the sections may be located at points other. than those shown, and also that, if desired, the top and bottom members-may be in one piece and integral throughout, respectively from end to end and side to side 0f the car.

In the drawing the end sill is shown as consisting of a vert-ical flange 1 and a top flange 1a, from which extend the vertical flanges 2 and top flanges 2a of the draft sills, connected in turn to the vertical ange 3 and the top flange 3a of the bolster.y These parts are preferably integral and constitute` the upper or top flanged section of the end of the underframe. section has/"a vertical flange 4 iuxtaposed to The bottom flanged side-bearings, as usual.

The .ends of the end sill and bolster members are preferably formed to receive fastening devices, by which they are respectively connected to side sill members 7, these latter being in the form of commercially This rolled channels and extending throughout thel length of the car. It is obvious, however, that the side sill members could be integral with the bolster and end sill members and ycross-bearing membersl of the underframe if desired.

The bottom section of the bolster member is preferably provided with an inwardly extending shelf-like projection 6b, from which extends a vertical web 6, slightly spaced apart from a companion web 3 on the upper section and between which is received vertiIcal web 8 of the centersill member. 8 has flanges8a and transversely extending vertical webs 9 which have top flanges 9a extending to the side sills.

10 is the vertical web of the bottom member of the cross-bearing section, which has flanges 10a riveted to the shelf`-like extension 6b, and Ivertical webs 11 juxtaposed to the webs 9 and preferably riveted thereto. Webs 11 have bottom flanges 11a; as shown in Fig. 6. The-vertical webs constituting the center sill members arelpreferably crossed over at the intersection of the cross bearing, as shown in Fig. 5, as are also the webs 9`and 11 ywhich constitute `the cross-bearing member. By virtue of this construction, when the parts are assembled and the vertical webs riveted together, `they will be* interlocked. Fig. 6 shows this crossing over of the webs 9 and 11.

At theextremities of the sections carrying the center sill and cross-bearing members, the vertical webs of the center sill portion. preferably extend beyond the horizontal ex tremities, so as to form splice plates.,as shown at 12, Fig. 2, wherebyv the parts are connected together, and, if desired, horizontal shelf-like extensions 12 may be provided on the top or bottom flanges, or both,

for the purpose ofstrengthening the connection.`

In Fig. 4, I have shown the end sill vertical Webs 1 and 4 as integral with the draft sillsv of the underframe.

In Fig. 7, I have shown the vertical webs 8 and 10 of the center sill on the top and bot-- tom members respectively as being in aline- .ment, that is, not crossed over.

In Fig. 8, I have shown the connection between the vertical Webs as being produced `by rivets passing through interposed washers 14; the object of these washers being to provide points of contact around the rivet openings only, thus leaving a space between themajor areas of the contiguous faces so that irregularities on the surfaces of the castings at this point may be compensated for.

. What I claim is:

1. A car underframe whose principal load-carrying members comprise juxtaposed transverse vand longitudinal integral webs v verse and longitudinal members, T shaped.

4. A car underframe composedof top and i bottom members, each of which has vertical webs juxtaposed to the vertical webs of the other member; said webs interlocking with each other and being connected to' gether to form` draft sills and` transverse members.

5. A car underframe composed of top and bottom members, each of which has vertical webs juxtaposed to the webs of the other member; said webs being arranged at right angles ltoeach other, interlocked and connected together.

6. A car underframe comprising top and bottom sections, Tshaped in cross section and vhaving longitudinal and transverse members with the vertical webs of said members juxtaposed to each other to form the draft members and bolster members.

.7. .A part of a car underframe composed off companion castings comprising transin cross section and having their vertical webs juxtaposed and connected together.

8. A part of a car underframe composed of companion top and bottom members, T shaped in cross section and whose vertical webs are juxtaposed and connected together; said webs being longitudinally and transversely dispose 9. A car underframe comprising top and bottom members whose vertical webs are juxtaposed and connected together' to form draft sills and cross bearings; said underframe being made up in sect-ions and having shelf extensions extending from one section under another.

10. A car'underframe comprising top and bottom members, Tshaped in cross section and whose vertical webs are juxtaposed and connected together; said webs being disposed longitudinally and transversely to form draft members and members for supporting side sills and interlocked with each other.

11. The car underframing having an end sill composed of top and bottom companion members formed with vertical webs which are juxtaposed andl connected togetherI to form both the face' of the end sill and members extending at right angles therefrom, to provide attaching faces for draft rigging. v

12. A car underframing having draft sills comprising upper and lower members hav` ,ing vertical webs which are juxtaposed and connected together, and which have laterally extending upper and lower members forming supports for side sills.

13. A car underframing having a bolster member composed of upper and lower members having vertical webs juxtaposed and connected together to form said bolster and part of the draft members.

. 14. A car underframing having a bolster member consisting of two oppositely-arranged T shaped members having extensions forming portions of longitudinal members and whose vertical ywebs are'juxtaposed and connected together. j

15. A car underframing having a longitudinal member, a cross-bearer formed on portions of said longitudinal member, said cross-bearer consisting of top and bottom T shaped members oppositely-disposed and having their vertical webs connected together.

16. A car underframing whose transverse and longitudinal.load-carrying parts consist of two oppositely-disposed T shaped members whose vertical webs are connected together.

17. A car underframe whose main loadcarrying parts consist of two oppositelydisposed T shaped members whose vertical webs are juxtaposed and connected together to form longitudinal and transverse members.

18. A car underframe whose draft and transversemembers consist 'of two oppoconnecting the extremities of the transsitely-dispsed T shaped members' whose versely-disposed members.

vertical webs are spaced apart and astenln testimony whereof I hereunto affix my ing devices passing through the spacing signature in the presence of two witnesses,

19. A car under rame 4consisting of an f end sill, draft sill, bolsters and cross-bearers, ALBER J MCCAULEY' all of said parts comprising two oppositely- 4lVitnesses: disposed T shaped members whose vertical M. P SMITH,

1o webs are connected together, and side sills Jnssm CLARK.
