SPECIFICATION forming part of Letters Patent No. 786,575, dated April 4, 1905. Application filed November 23, 1904. Serial No. 234,035.

To all 1/710711 if III/Ill] concern:

Be it known that l. ARTHUR Liesonurz, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented a ccrtain ncw, useful, and Improved ('ast-Steel Car-Truck, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming-a part of this specification, in which i Figure l is a side elevation of a car-truck ei'nbodying my invention. Fig. 2 is a plan view of onehalf of the car-truck, the truckbolster having been removed to disclose the spring-seal. which is formed upon the truck beam or side frame. Fig. 3 is an end elevation of the truck, one-half thereof being in vertical section on the lines 3 8" of Fig. 1. Fig. i is a transverse vertical section of the side or truck beam on the line B P of Figs. 1 and Q, and Fig. 5 is a detailed side elevation of the truck-beam above referred to.

This invention relates to railway-trucks composed of metal, and has special reference to improvements in trucks of that class where-- in the journal-boxes are rigidly secured in the truck-frame and whercin'the truck-bol--- ster is supported by springs upon the side f'ames of the truck as distinguished from those trucks wherein the bolster is supported bytransverse transoms. in a truck of this general class the truck-bolster is generally quite as long as the car-axles, and its ends extend through or be 0nd the side frames, the springs for supporting the bolster being arranged substantially in the vertical planes of the said frames. c

My invention relates particularly to improvements in the side frames of trucks,

. though not particularly or specially confine-d to such parts.

The object of the invention is to provide a car-truck which shall be of. less weight and cost than others of this class and which shall he. composed of fewer parts.

Another and distinct object of the inveniion is to so improve the construction of the side frames of car-trucks as to provide ample spaces for the bolster-springs and yet afford ample strength, and. furthermore, enable the the placement and the removal of the bolster without requiring the side frames to be taken down or dismembered. r

A further objectof my invention is to provide a bolster supporting and guiding Ll'utgli frame or beam that may be made in a single piece. I

The particular object of the invention is to proride'a. car-truck in which the usual transoms shall be dispensed with and in which single-part truck-beams, one on each side of the truck, shalltake the place of the arch-bars, truck-columns, spring-seats, and minor associated parts commonly used to connect the journal-boxes of a truck and support the ends of the truck-bolster.

ventioh is to provide scar-truck of the described class'whereof the chief members may be made of cast-steel.

Broadly defined, my invention consists in a 'car-truck'thatis characterized by side beams which have tops that are adapted to guideand support the truck-bolster and the ends of which beams restupon and are secured to the tops of the journalboxes of the truck, and a further: characteristic of my invention is that the bolster end guide openings or jaws in the sides of mytruck are. open at the top, so that the bolster may lie-removed without disturb ing any other part of the, truck except the light detachable bolstea-stops.

Specifically dclincthmy invention embraces and resides in a truck having sidc beams that are provided with upwardly-extcnding bolster-columns and an expanded or widened top, which latter is preferably integral with the beam and serves as the seat for the bolstersprings. The side members thus equipped with spring-seats and bolster-guides l generally make of cast-steel, and my invention desire, however, to state that though I prefer that eacl. distinct complete member of my truck shall be a single metal, preferably steel, casting, said membe'rsmay be constructed of one or more pieces of rolled, pressed, or cast metal, and I do not limit my invention to a A further and particular object of the in takes its special name from these castings.

Because of this shnpez'of, the beams the bolsten. is, in effect, swung or hung lroin the tops of the journal-boxes, and its lateral thrusthas little torsional effect upon the hlHClPlJQ-RER'IS.

The ends of the beam are straight and rest squarely upon the tor ot' the jGLllZDQl'bOXQS. The bottom of the beam is substantially in the plane of the bottoms of the journal-boxes, end the tie-oar 5 is bolted or otherwise secured to the lizo-ttom flange 11' of the truck-beams. Large bolts 13', extending between the ends of the beam 4: end the tie-bar 5, embrace the boxes 3 to bind the parts end 5 firmly upon said journal-boxes: The bolts pass through,

Referring to Fi 5, it will be seen that the side beam is provided with a bolster-space that is open at the top, being formed by the jaws or columns 1% that rise from the ten of the beam.

The angles perform the office of preventing the spreadingapart of the two truck-beams, being assisted therein by. the column and columnguides of the bolster.

, beams and hangers.

and, with a simple bar, constitutes the means for securing the bolster and spring in proper place. In addition to these functions I make the side beams of my truck toperform the further service of supporting the brake-beams of-the truck- The brake mechanism of the truck is not shown in the drawings; but it will be seen that each truck-beam is provided with two vertical bracket-likewebs 19, arranged upon the upper inner side thereof 'abovethe top web 10. These brackets 19 are preferably integral with the columns or bolster-guide 14 and areprovided with lugs 20, having holes for pins and adapted to support the brake- Thus the columns or the spring-seat plate, or

both, may be formed separately and bolted or fastened upon the top of the beam proper.

This is alsotrue of the brake-hanger lugs,

and it is also obvious that both the longitudinal and the cross-section of the truck-beam,

as herein shown, may be modified to meet special requirements, and generally, as it is obvious that numerous modifications of my invention will readily suggest themselves to one skilled in theart, I do not confine the invention to. the specific constructions herein shown anddescribed. I
