CARP'UNDERFRAME.

i as'will enable others skilled in the arty to which it appertains to make and to use the same, reference being' had to the accom vanying drawings, which illustrate the .pre erred form of the invention, though .it isto be understood that' the invention is not limited to the exactdetails ofconstriiction shown and described, as itis obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a plan view y The object of the invention-is to provide asimple, light and strong metal underframe fork railway ears with a single plate girder center sill in which the compression member isdivided at the rear of thev bolsters and passes beyond saidbolsters to form draft members either extending to end sillswith-l out interruption or serving as supporting means for separatedraft beams or sills `rwhich may be connected therewith as is commonly done withy the ends of separated center sills which extend beyond thebolsters. In this car the greater part or all the load is carried by the single plate girder center sill, the web and tension member of which terminate Vpreferably between the holsters and the compression 'member extends fromv end sill to end sillto serve bei tween the holsters as parts of the center sill land beyond the holsters as draft :sills whereat the said compression 'members'are sep- Specication of Letters Patent.

` arated c suiiiciently `to .receive between" ',tliemV the usual draft rigging, notshown'. V*For the pur ose of securing the rearl end vortion's o these draft Asill extensions 'bo ster filler castings areprovidedwhich haverela tively parallel sidefaces and curved rear portions and the-'draft sills are riveted; to

said filler castings and to the upstanding inner vianges of the bolster diaphraglnswhile a continuous sill cover plate connects center sill. Continuous yZ-sha'ped sidesill,

members are supported by the' ends'ofrzthe bolsters and transverse 'members andfon these sills are carried the usual side nailing strips, shown in dotted linesin Fig.'Y 3,

though it is evident thatother forms of side sills or their vequivalent may vbe substituted if desired, this invention relatingprincipally to the monosill funderframe; andi its associated parts as used in one construction.

Referring to the parts, Av is the "single center sill of plate girder formr extending relatively `from `near the bolsterA B shown to the same relative distance 'from its companion bolster at the otherend fpor-V tion of the 'cal'. Said holsters comprise pressed. diaphragms 2, top and bottqmeoyer plates 3 4, center-castings 5, and` flanged4 plate 6, by means of which the ,'Zfsliiiped side sills 7 are connected therewith. f

The center casting differs invformfrom that usually' employed in thatl the reanportion thereof 8 is curved to better adapt it for use in connection \vith..thlelpeculiarV `bers which extend from the end sillsklfO' in parallel lines past the bolsterdia'phragms and there converge as shown ,in Figflto .form parts of the compression member 1.1'

tion of the web platerare securedapair of angles 13 which are. substantially coextendiverging from the ends of said web plate 65 l sive with said web plate as best shown'in Fig. 2.

Resting on the upper flanges of the niembers 11 is a longitudinally extending -sill cover plate 14 which may he duplicated, if desired, and said sill cover plate extends to and is secured to the bolster cover plates 3 by suitable rivets.

Extending transversely of the car underframe are truss members comprising the upper channels 15 which extend over the center sills and to the side sills, and the lower channels 16 which extend below and are secured to the-bottom flanges of said Z-shaped side sills and extend through the web plate 12 of the center sill, as4 best shown in Figs. 2 and 4. i a i Connecting the top and bottom channel members 16 are webs 17 of channel form which are securelyV riveted in position. Above the tension'angles 13 of the center sills are brackets 18 which are provided with laterally extending flanges 19 through which rivets extend to secure said flanges to the webs of the compression members, the web 12 and the upper legs of the tension angles 13, said brackets 18 being cutaway as shown at 2,0, to accommodate the lower flanges of the compression members 11.

It will be observed that the bottom members 1G of the transversely extending truss, just described, extending through the web plate 12 causes said web plate and the compression members 11` to serve as struts for the transversely extending truss.

Between the transversely extending trusses and the holsters are cross bearers 22 of channel form in cross section which are secured by suitable flanged plates 23 to the side sills and to the compression members of the ,center sills. Extending from the holsters are diagonal braces 24- which are preferably angle shaped in cross section, and said diagonal braces have their vertical legs cut away so that the horizontal legs thereof may pass over the top cover plates 3 of the holsters and be secured to said .top cover plates and to the outstanding horizontal flanges of the holster diaphragms, as best shown in Fig. 1. The opposite or outer endsv of said diagonal braces also have their vertical legs cut away and the horizontal flanges thereof are se-` cured to the plates25 which are riveted to the upper flanges of the ,channel shaped end sills andto the Z-shaped side sills.

lfVhat is claimed as new is: 1. In a .car underframe, the combination comprising holsters each with an opening relatively at the middle thereof, a. filler in each of said bolster openings, a single built- -up center girder with a vertical web' plate between saidv holsters, compression members forming parts of said center girder and and extending through said holster' lat each side of said bolster filler, and a cover plate extending between and connecting said hol- Y sters.

2.A In a car underframe, the combination with side sills, holsters, a, built-up plate girder center sill with tension members terminating between said holsters and compression members diverging from the ends of said tension members and extending 'heyond said'bolsters, a sill cover plate connected with said holsters, and filling members within relatively central openings of said holsters and separating the extensions of said compression members.

3. In a car underframe, the combination with side sills, holsters, a plate girder center sill with tension members terminating between said holsters and compression members extending beyond said holsters, and a transverse truss one member of which extends below said side sills and through the web plate of said center sill.

4. In a car underframe, the combination with side sills, holsters, a plate. girder center sill with tension members terminating between said holsters and compression members extending beyond said holsters, and a cross bearer having olie member extending to said side sills and another member pass.

(5. In a railway car, the combination comprising holsters, end sills and channel shaped draft sills between each holster and end sill, said draft sills converging between said holsters and being connected together, and means clamped between the connected portions'of said draft sills connecting all of said draft sills together.

7. A car provided with a single plate girder center sill extending from end sill to end sill and provided with an intermediate weh and tension member said web and tension members terminating between the holsters, said sill comprising separately formed compression members diverging from the ends of said tension member.

8. A car provided, with a flanged web cenvter sill, a pair of channel shaped draft sills secured to said center sill web between the holsters and senii-circular holster `fillers fitted between curved portions of said draft sills.

9. A car underframe comprising a holioo ster and a single plate girder center sill, coincident with the points of divergence of said center sill comprising a compression said center sill, anda Cover plate of said member` extending beyond said bolster and center sill extending beyond the ends of said a :Web plate and tension member terminat- Web plate and being fixed to said bolster's.
