Our invention relates filler assembly for the center sills of railway cars. The center sill filler now approved by the American Association of Railroads is objection able in that it is made as a one piece casting. It;;

to a new and improved 7 Claims. (01. 213-417) is, therefore, necessary to machine the sides of casting now acceptable. Due to the limited working space between the center sills of the car and the consequent inaccessibility of some parts of the structure requiring welding, all attempts to provide a satisfactory welded center sill filler have been unsuccessful.

The primary object of the present invention is to provide a welded filler block assembly which 7 may be completely formed in sections with the use of suitable jigs prior to insertion between the center sills Of the car.

A primary feature of the invention consists in providing a filler block assembly formed of two,

separate castings respectively secured to rolled sections which are adapted to be attached to the center sills of the car, the castings being secured to the rolled sections and to each other before the assembly is inserted between the center sills of the car.

Another feature of the invention consists in providing the castings of the filler assembly with curved portions which, when the castings are suitably secured together, mutually cooperate to provide a king pin receiving opening.

A further feature of the invention consists-in respectively providing a pair of oppositely disposed members with rigid castings, each of which has an upright portion which is welded at one edge to one of said members and is formed with a curved portion adjacent the other edge, the castings being rigidly connected so that the curved portions thereof will cooperate to mutually form a king pin receiving opening.

A still further feature of the invention consists in providing a filler block assembly having castings respectively welded to oppositely arranged members, the castings being Welded together in a direction which is substantially parallel with;

the longitudinal axis of the car and the members being adapted to be secured to the center sills after the castings are secured to each other.

A still further feature of the invention consists in providing a combined center sill and rear .draft gear stop assembly involving a pair of castings respectively rigid with a pair of oppositely disposed members, rear draft gear stops being welded to the forward ends of said members and reinforced by substantially horizontally arranged ribs welded to the members, the members being adapted to be respectively secured to the center sills of the car after the castings have been welded to each other.

Other and more specific features of the invention, residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be pointed out in the appended claims.

Figure 8 is a detail view taken on line 88 of Figure 3.

Referring more particularly to the drawings, I indicates the center sills of the car, each of which is preferably of Z section having a web 2 and oppositely projecting top and

bottom flanges

3 and 4. The free edges of the top flanges of the sills are conveniently disposed contiguously to each other so that they may be welded securely together as indicated at 5.

The filler block. assembly may advantageously employ a pair of inwardly opening rolled members 6 of channel section. These members may 7 be twelve inch standard channel sections each havin top and bottom flanges I and 8 respectively connected by a web 9. Secured to each of the members 6, preferably by welding, is a casting I0 formed with a web II and a base plate portion l2. The upright web of each casting is welded, as indicated at l3, to the web 9 as well 3 as to the top flange l of the channel with which the casting is associated. The free end of the web of each casting is formed with a circular portion [4 which extends on opposite sides of the web and its axis of curvature is substantially vertical.

Integrally formed with one edge of each curved portionld.is..a..rigidifying rib-.|.5 adapted to extend substantially longitudinally of the car. The outer face of the rib of each casting preferably terminates in line with the free edge of the other part of the curved portion and they both are advantageously in line with thezaxi'sroficurvature. By this construction, neither of the..cast-. ings is right nor left. At its upper'emi thezrigidifying rib l5 merges into an inclined top fl'ange [6 of the casting and at itsloweriendiit'isinttegrally formed with the base [2.

The curved portions [4 of the castingsare preferably so formed that, when the castings are f secured to-eaclr other, they fo'rm a'sub'stantially vertical opening forreceiving a king pin (not shown) which affords a pivotal comoection betrucki- The-castingsmay be advantageously connected by being welded: as indicated at- H, which may extend continuously along the inner face of "the rigidifying rib M of each casting where I2 where they abut the rigidifying ribs of the castings; The wcastingsmay also-be-weld'ed, as indicated at [9, along-the under sides of the-base portions ofthe castings without the necessity" of grinding because-the welded areaof the bases is' sufficiently spaced above the-lowest portions thereof-f Before the castings are securedtogether' and j theassembly thereafter" inserted between the center-sills; thecastings" are separately secured to' their cooperating channel sections;- The two parts of the center filler may, therefore, be easing to itsmemb'er; as indicated at l3; the upper edge of the top flange 16 may also be welded, as-shown at 24-, to thetop flange-1 'of the member'and the base plate lz 'may'be'welded, as at 25, to the bottom-flange=8. The-base portionu of'each casting may be also secured to its associated member by a pair of 'rivets 26 which pass through lugs or ears- ZIQfthe base plate and the 'outerportions of the bottom flange 8 of member 6, it being seen that the'ears or lugs restl uponthe-top ofthatflange. To prevent the rein-forcing ribs-22"of' the back stop" from interferingwith" eitherthe'driving or bucking of the rivets26; each of the ribs'22"'is cut away, as inf dicated at -28, and continues 'rearwardly substanti'ally reducedin'width'to the webll of the adj acent'casting.

Fillerstrips 29' are preferably tack welded at their-opposite ends; as indicated at 30'tothe top tweerrthebodyof the-'raili'oad carand the car it *abuts'the curved portion-of the other-casting.

In addition, the castings-may bewel'ded, asindicated'at l8; along thetop 'of thebase plates der side of the top flanges 3 of the center sill so as to vertically position the assembly correctly within the sills. A rear tie plate 3| of conventional construction may also be tack welded to the top flange 1 of one of the members 6. After the castings are separately welded to their channels 6 they are brought together into contiguous relation andweldedto each other as previously described.

By assembling one-half of the center filler independently of the other, it is possible to securely weld to each channel all parts of the device connected to it. As previously indicated, the. two main parts of the filler are separately assembled on jigs so that, when the two parts are welded together, they form a rigid center filler-1' assembly of" the width desired for insertion between the center sills. The necessity of compromising design or of risking the failure to weld or of other means of attachment is entirely eliminated, since the partsof the filler which would be inaccessible'for welding when the filler is inposition between the center sills may be easilywelded to'th'e rolled sections before the two parts of the filler are welded'together and placed between the sills. Even the welding together of the two main parts of the filler is preferably accomplished before the filler'is placed between the sills. Thus an extremely rigid'and all-welded center filler is provided.

The webs 9 of the channels Band the webs 2'of the center sills are formed with aligned openings so that, after the flller is placed between the sills, rivets may be'inserted the openings for securely connecting the center filler to the center sills. The top flanges Tof'the channel 6, together with the fillers 29, may also be-advantageously formedwith aligned openings for registering with similar openings in the'top-flanges 3 of the center sill to receive additional rivets for connecting the filler to the sills.

It will, of course, be appreciated that by using conventional channel sections 6, sections of the desired length may be obtained by simple cutting. Various-changes and modifications may be made in the structure illustrated and described without departing from the spirit and scope of the invention as defined in the appended-claims.
