CAR-BOLSTER.

Specicaton of Letters Patent.

Patented Mar. 26,

Application led October 26, 19H. Serial No. 656,827.

To all whom 'it may concern.'

Be it known that I, JOHN MCE. AMES, residing at Dongan Hills, Staten Island, NeuT York, and being a citizen of the United States, have invented certain new and useful Improvements in Car-Bolsters, of which the following is a full, clear, and exact descri tion, such as will enable others skilled 1n the art to Which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate thefpreferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construei .tion shown and described7 as it is obvious that various modifications thereof Will occur to. persons skilled in the art.

#In said drawings: Figure 1 is an elevationalrview of the bolster. Fig. 2 is a plan View. Fig. 3 is an end view. Fig. 4 a sectional viewvthe section being taken on line rI`he object of the invention is to provide asiinple, strong and light cast bolster especially adapted for tank carservic, in the construction of which car side sills are omitted. the bolster extending at its base outwardly to combine therewith side bearings and at the top to form a tank cradle of sullicient length to properly support tanks up to 10,000 gallons capacity or over, a feature of the invention being the omission of the greater portion of the vertical bolster web in the vicinityT of the center sills of the car so as to permit of considerable transverse and rotative movement of such sills when being applied and connected with the bolster, as well as to provide a '.vide gap between said sills and the bolster web. when the sills are in position, so as to permit ready mani ulation of riveting tools used to rivet the Sil s and bolster together. To that end the bolster shown is a single casting comprising integral to and bottom connecting plates between Wiieli are the vertically disposed sillattaehing flanges (so called) and beyond these flanges come the sill gaps, While beyond said sill gaps are provided triangular extensions which,y along their upper faces, receive YWood tiller blocks upon which rests the tank and said triangles terminate at,

their lower angles in bolster side bearings adapted to coperate with the usual side A.

bearings carried by the car trucks. p 1

Referring to the parts, 1 is the bottoni plate which is Wider near its middle portion than near the ends and is provided at `its middle portion with a center bearing exten! sion 2 adapted to cooperate with the center bearing plate usually carried by the truck.

3-3 are longitudinally extending flanges which project downwardly'and outwardly from the plate 1 and serve as reinforcing flanges.

Disposed centrally above the, plate 1 isa: pin socket 4 which is connected by a vertical` web 5 with what are herein called sill at;` taching flanges 6, said flanges com arising vertical Walls which extend from the ott'oni` plate 1 to the top plate 7 of the bolster, the usual pin gap 8a being provided in the web 5 between the sill llanges G. The bottoni*y plate l beyond the flanges 3 is provided withV laterally extending flanges 8, which curve upwardly to near the vicinity of the `-ob liquely disposed ribs 9, thence downwardly and outwardly in relatively horizontal lines to form the side bearings 10.

Extending inwardly from the top and bot`- toni plates and the ribs 9 are bolstervv'ebs?. 11 which terminate a considerable dist-ance" from the sill flanges 6, before referred to,' thus providing sill gaps Whiohare Wfl-def enough to permit of' projecting the sills:7 .i

through said sill gaps while said sills are yin horizontal position: then rotating suoli sills to vertical position; that is, with the webs of the sills in contact with the sill attaching flanges 6. Between the top and bottom innerl ends of these flanges 11 the limer face of'tliel top and bottoni bolster plates 1.7 are pref--l erablyY flattened, as shown in Fig. 1, so as to provide a iride flaty bearing upon which may i rest the supporting sills of the car durmg.

the time the underfralne parts ,rc being assembled and after the sills are riveted in position to the [langes G. The gaps 12 thus provided between the top and bottom bolsterI i plates, the flanges 6 and the webs 11 are of` sufficient extent to permit ready insertionJO sills heilig projected through said gaps while said center sills are provided with draft lugs,

and such appurtenances as are commonly connected with center sills in tank oars, and

- ferred to.

the aps extend suiliciently to permit the sills eing projected through said gaps while the sills are horizontally and obliquely disposed, after which the sills may be placed in vertical position upon the sill seats 1" and moved inwardly into contact with the flanges 6, to which flanges said sills are secured by rivet connection, the gaps 12 being large enough to ass the riveting tools used to secure the sil s in'position through said gaps, thus permitting the use of pneumatic or other riveting tools and materially redueing the cost of assembling the underframe parts.

The to bolster plate 7 is, as shown in Fig. 1, flliit or provided with horizontally projecting flanges 13 throughout its middle portion and rises obliquely upwardly to provide seats for the wood blocks 14 which are shown in position in Fig. 1 and in the left hand portions of Fig. 2. i

The top plate is provided with longitudinally extending strengthening ribs 15 which extend outwardly from the vicinity of the sill flanges 6 and extend slightly beyond the ribs 9, thereby providing side walls for the inner`ends of the wood blocks 14, before re- This top bolster plate is reinforced also by means of a thickened portion 16 which is deepest above the bolster webs 11 and gradually decreases inthickness, as shown in the sectional view Fig. 4, disappearing in the flanges 13 at or near the out` ward extremities of said flanges above the middle portion of the bolster and this thickened portion sharply converges, as shown in the plan view Fig. 2, terminating near its outer ends in inclined seats 17, against which seats rest. the inner ends of the wood blocks 14. Thus the wood blocks 14 are held in position at their inner ends by contact with the abutments 17 and by the vertical flanges 15, while the outer end portions of said wood blocks are recessed and tit over the integral studs A18 which extend above the top plate portions 7 as best shown in Figs. 1 and 2. Beyond the studs 18 the bolster is bifureated. as best shown in the plan view Fig. 2. and perforations 19 extend through the hifnieated portion of the bolster. This bifurcation is provided so as to permit connecting with the bolster yokes adapted to receive either the lower ends of tank bands eonnnonly used in tank cars, or as means for supporting running boards. but as this invention relates solely to the bolster, such connections are not shown.

.Extending obliquely downwardly from the hifureated outer ends of the holster are ribs 20 which, with the ,oblique ribs 9 and the oblique extensions 7 ilate, forni triangles terminating at their hase in the side bearings 10 before referred to, and between these ribs is a web portion 2l which projects inwardly, as best shown of the top holsteinL in Fig. 1. Projecting outwardly and downwardly from the obllque ribs 20 are lugs 22 which are preferably perforated and serve as supports for means adapted to support' running boards not shown.

Bytie terni plate as here used I do not mean to indicate a separately formed sheet metal plate commonly used as a bolster cover plate', but refer generally to the somewhat flattened top and bottom bolster portions cast integral with and which serve as connectors for the laterally extending ,tri- `angular parts indicated.

The bolster designed for service is' intended to be used with channel cen'ter sills and assuming said sills to be 13 channels the 'gaps 12 would be more than 13 across at their lon est measurement so as to permit the sills to ge turned on their sides and ma nipulated as may be through the said ga/ps.

What I claim is:

1. In an integral cast bolster, a. plurality of relatively triangular flanged portions terminating in side bearings, a connecting bottoni portion comprising a pin socket and sill attaching flanges and a continuous top portion provided with timber retaining means.

2. A tank car bolster comprising an integral casting, having triangular upwardly extending portions terminating in side bear? necessary to pass ports at their upper portions, top and bottoni connecting portions, en intermediate center pin socket and sill attaching flanges and having enlarged sill gaps between said portions.

3. A tank car bolster comprising an integral casting, having inwardly flanged triangular upwardly extending portions terminating in side bearings at their lower ends and in tank supports at their upper portions,l top and bottom connecting portions, an intermediate center pin socket and sill attacli' ing flanges. and having enlarged sill gaps between said portions.

gral casting, having triangular upwardly extending portions terminating ,in side bearings at their lower ends and in 'tank supports at their upper portions, longitud' al y flanged top and bottom connecting por 0 an intermediate center pin socket and attaching flanges, and having enlargedv gil gaps between said ortions.
