Application filed April 5, 1912. Serial No. 688,629. Y- I To all whom it mag/convent: Y side' elevational` view, par-'ts beingl broken Be it known that I, GUsTAv KOMAREK, a citizen of the United St-ates, residing in St.. Louis and State of Missouri, have invented certain new andv useful Improvements in Car-Trucks, of which the following is a specification. j
My invention relates in general toA carl trucks, and moreparticularly to car trucks having cast metal side frames. i
rlhe form of cast metal sideframes for trucks in most general use at the present`l vtime comprises a pair of spaced columns cast integrally with the side frames, a portion of the bolster opening between the` columns being. widened to permit the passage between t-he columns of the end of a bolster having integral column guides on the sides thereof. In this form of cast side frames, the springs alone serve to retain the holster ends'within the upper contracted. portions of the bolster openings, and should the ends of the bolster accidentally :be lowered to register with the widened portions of the openings between the columns, the bolster Wouldbecome disconnected from the side frames. Furthermore, the greatest L wear to which truck side frames are subjected is upon the columns, owing to the constant vertical movement of the bolster ends relatively to the colunms, and as the columns are formed integrally with the side frames they cannot be replaced when worn.
My invention has for its object to provide a car truck of the type having cast. metal side'frames with means for permitting the convenient assembli of the` bolster with the side frames, which will prevent any* danger ofthe accidentaldisconnection of the bolster from, the side frames; which will permit the'convenient disassemblin of the j bolster from the side frames; an which ,will enable new columns to be readily substituted for worn columns.
A further 4object of my invention 1s. to
provide a car truck which will be strong and durable in use, and which will comprise parts. capable of being readily assembledI into secure operative relation, and also readily disassembled should occasion require.
My inventionl will be more fully described hereinafter with reerence to the accompanying drawing, in which the same is illus- Atrated as embodied in a convenient and practical form, and in which-Figure 1- is s.
The .same reference characters are used tov designate the saine parts in the several Iiguresof the dra Reference 'character A" designates the upper bar and reference character A2 the lower bar of a truck side frame formed in an integral casting.
B and B2 indicate the upper portions of' journal boxes which are also formed integrally with the cast metal side frame.
b, b2 indicate the lower portions of the respective journal boxes 'which are detachably secured to the upper portions. So far as my invention is concerned however, it'is not material whether part or all of each journal -box -is cast integrally with the side frame. My invention does not reside in, nor is it limited to, divided journalboxes as illustrated in the drawing. Nor is my invention restricted to a cast metal side frame, the bars of which are I-shaped in cross section, as the upper and lower bars which are formed in a single integral casting may have other cross sections without depart-ing from my invention.
The upper surface of the horizontal central portion of the lower bar A2 is widened to form an integral iiange a2 which serves as a spring seat, asjwill he clear fronrthe subsequent descriptionfw Q' rand C2 indicate transverse members ffor rigidly connecting the side frames Yof my improved car truck, each of said transverse members being Iformed in an integral casting and comprislng columns atits lopposite ends of a height to lit between the upper and' lower bars of the side frames. The transverse member C comprises vertical hollow columnsrc, o?, whichare connected at their lower ends by the bar c which is preferablyangular in cross section. 1 .The iother" The transversemembers C and C2 are assembled with the side frames by inserting the columns c', c2 between the upper and lower bars ofthe sideI frames, 'the columns y E2 extend vertically through the columns c',
c2 and also through registering openings formed in the barsy of the respective side frames. e and e2 indicate nuts located upon the lower screw threaded ends of the bolts which project below the under surface of the lower bar of the side frames..
The transverse members of the truck frame C and C2 are assembled with the sideframes with the horizontal flanges of their connecting bars c extending toward each other and seated at their ends upon the A spring seats a2 formed integrally with the tical surfaces of the ends of which are prolower bars of the side frames. The spring seats are preferably cut away so that the central portions thereof will be flush with the horizontal inwardly projecting anges of the angle bars ofthe transverse members. Suitable fastening devices, such, for
instance, as rivets e, secure the horizontal flanges of thercross bars to the underlying portions of the spring seats.
D and D2 indicate inwardly extending brackets formed integrally with the columns and each comprising a pair of apertured ears d', d2 fromwhich may be hung any suitable form of brake hanger.
F designates a bolster, the'opposite vervided with spaced pairs of column guides f", f2 which engage the outer and'inner surfaces of the respective columns c and 02 so as to securely unite the bolster with the side frames but lat the same time so as to permit a free vertical movement of the ends of the bolster relatively to the columns.
G andy G2 designate nests of springs which support the ends of the bolster and are supported between columns upon the spring seatsofthe side frames.
g and g2 indicate woodenbloclrs interposed between the lowerends of the springs and the spring seats.
In assembling the parts of my improved car. truck, the bolster is placed between the transverse members with the pairs of columns located between the column guides on the bolster ends, after which theI transverse members with the bolster between them are secured to the side frames by inserting the columnslbetween the upper and lower bars of the side frames and then passing the bolts through the registering holes in the top'and bottom bars and intermediate col` u nins. The ends of the horizontal flanges of the angle bars forming parts of the transverse members are then secured by the rivets e to the spring seats. The springs are then interposed between the spring seats and the ends of the bolster.
F rom the foregoing description it will be observed that I have invented an improved car truckcomprising cast metal side frames and two cast transverse members rigidly,
though detachably, -secured to the side frames and serving to securely retain the bolster in locked engagement with the side frames. It will be further observed that each of the transverse members is in the form of an integral casting comprising a bar, at the ends .of which columns project at right angles thereto, and that by providing two of such transverseY members suitably spaced apart, the pairs of columns for guiding the bolster ends are formed between thel upper and lower bars of the side frames.
While I have described more or less in detail the specific form in which I have illustrated my invention as embodied, yet I do* not wish to be understood as limiting myself thereto, as I contemplate changes. 1n form, proportio-n of parts, and' substitution of equivalents, as circumstances may require, or as may be deemed expedient.
l. In a car truck, the combination with cast metal side frames cach-comprising integral vtop and bottom bars, of a pair of transverse cast metal members each comprising a column at each end thereof and an intermediatev angle bar cast integrally with the `columns and unit-ing the lower ends thereof, and means' for securing said trans' verse members to the side frames with'the col umns on their corresponding ends spaced apart to form openings for the end ofthe ybolster and with the horizontal flanges of the angle bars extending toward each other at the bottoms of the said bolster openings.
.2( In a car truck, the combination with cast .metal side frames each comprising integral top and bottom bars, of a pair of transverse cast metal members each corn-v prising a column at each end thereof and an intermediate angle bar cast integrally with theV columns and uniting the lower ends thereof, and bolts passing vertically through the to-l`r andbottom bars of the side frames and through the interposed columns, thereby uniting the tra-nsverse membersto the side frames and spacing apart the columns on the bers to form openings for the ends of the bolster, the horizontal flanges of the angle bars extending toward each other at the bottoms ofthe said bolster openings.
3. In a car truck, the combination with cast metal side frames each comprising integral top and bottom bars, of a pair of transverse cast metal members each comprising a column at each end thereof and an intermedate angle bar cast. integrally with the columns and uniting the lower ends thereof, means sec ring the 'columns of the' transverse mem ers between the upper and lower bars of the side frames toform openings for 11-5 corresponding ends of the transverse mem? the ends of the bolster, a spring seat formed integrally with the upper surface of the central portion of the lower bar of each side formed integrally on the upper surface of' the central portion of the bottom bar, of a pair of transverse cast metal members each comprising a column at each end thereof and an intermediate anglev bar cast integrally with the columns and uniting the lower Aends thereof, the spring seats being -cut away to receive the horizontal ianges of the adjacent ends of the angle bars, and means for securing the columns between the top and bottom bars of the side frames and for securing the horizontal fianges of the angle bars to the spring seats. i
'5. In a car truck, the combination with' j cast metal side frames, each comprising integral top and bottom bars, of a pair of transverse cast metal members each 'compris-x ing a column at each end thereof and a brake hanger bracket projecting inwardly from each column, each of said transverse members also comprising an angle bar cast integrally with the columns and uniting the lower ends thereof, and means for securing the said transverse members to the side frames with the columns on their corresponding ends s aced apart to form open- `ings` for the en s of the bolster-'and with the horizontal anges of the angle bars extendin toward each other at the bottoms of the said bolster openings. a
