RAILWAY TRUCK.

Application filed August 1, 1924. Serial No. 729,440.

This invention relates to improvements in trucks for railway cars. 7

One of the objects ofthe invention is the provision of new and improved means for retaining in proper position the columns of railway trucks of the arch bar type which, through use, or displaced.

Another object of the invention is the provision of a new and improved brake supporting bracket for a railway truck.

Other objects of the invention are the provision or a truck column retainer member or clip that is cheap to manufacture, simple in construction, easily assembled in position on the truck, and when as'sembled will hold he corresponding column rigidly in position.

Other and further objects and advantages of the invention will appear from the following description taken in connection with the accompanying drawings, in which- Fig. 1 is a side. elevation of a truck of a railway car, with parts broken away;

. Fig. 2 is a section on line 2-2 of Fig. 1;

Fig, 3 is a section on line 33 of Fig. 1;

Fig. 4: is a top plan view of the device shown in Fig. 3 withthe head of the bolt removed; I

Fig. 5 is a detail o'f thefiller member; r Fig. 6 is a side elevation of a port on of a railway truck showing my'mvention in position thereon; r Fig. isa plan view of the same; I I

Fig. 8fis a section on line 8-8 of Fig. 6, with parts broken away; and Fig. 9 is a side elevation at right angles to that shown inFig. 8. r In the present construction of railway trucks of the arch bar type, the continual movement ofthebolster. relatively to the guiding columns and the strains and stresses between thesame often results in breaking and spreading the upper ends of'the -columns, which necessitates replac ng the mutilatedcolumns with new ones at con-- siclerable' expense. Furthermore, it is not uncommon for the brake supporting eyes onfthe truck columns to become broken oil inus; n ce i ating t sub u ion f 1 columns at .a 'oonsiderable expenditure of timea'nd labor. :My invent oncontemplates tlhelprovislon meansthat willflavoid. the neoessitybf sub have become deranged above. "to illustrate"o ne embodiment of the inof simple and"'inexpensive" or cli I stituting new columns for the mutilated or displaced ones.

On the drawing the reference character 10 designates a truck for a railway car comprising the upper and lower arch bars 11 and 12, respectively, the columns 13 interposed between the arch bars, a bolster 14 vertically movable between said columns and guided thereby, springs 15 for supporting said bolster and bolts 16 for holding the parts in assembled relation, all of which are of the usual or of any well known construction. The upper and lower arch bars 11 and 12, the columns 13 and bolts 16 mayv be considered as forming a truss for supporting the bolster 14 for carrying the same by the wheels 5. The columns 13 are provided with brackets or lugs 8 to which the brake supporting links 9 are adapted to be pivotally attached, and with grooves facing inwardly for receiving the bolts 16. They upper ends of the columns 13 are provided with flanges 17 extending upwardly at each side of the upper arch bar 11, see Figs. 1 and 2, for preventing lateral movement of said columns.

The rough usage to which railway trucks are subjected in the sudden starting, stop ping and bumping of-the cars often results -in spreading apart the top ends of the columns. It has been proposed to employ tie barsexten'ding from one column to the other toremedy this defect, but the use of these devices necessitates the insertion of thetie' bars between the top arch bar and 1 thecolumns, which is objectionable because it not onlyispreads the arch bars apart but raises the upper arch bar 11 out of the channels formedby the flanges 17. thereby dew priving the top arch bar of its necessary lateral support. V

Suitable means are provided 'for holding the columns 13; in position which does not possess In the vform of the device selected 'vention clip or; anchoring device provided for each column "and the parts are so constructed that when in position thecoL uinns are securely held within the recess or channel 'zformed 'by the flanges" 17. "As

shown in Figs. 'lfto ft, the anchoringdevice comprises body portion 18 ha ving ange's ""19 adapted 'toextend downthe objectionable features noted which the columns have become distorted or'-- spread apart, the top ar h bar is unfastened, the bolts 16 removed, the columns are 'straightenedor placed in normal position,

ioppositeside of the bolt and the anchoring devices are threaded on the top arch bar. The bolts 16 are replaced through the alined openings in the anchoring devices and arch bars and the parts secured in position in the usual manner. The clip or anchoring device forms a washer for the bolt 16. The top of the r p *ticn 18 may be, and preferably is,

provided with an upwardly extending lug 20 for engaging one side of the head of the bolt 16 to prevent the same from turning.

'The opening 21 in the body portion is preferably elongated whereby the same is adapted to be employed in connection with columns of ditterent widths. A. crescen shaped filler block 23 is adapted to occupy thatportion of the opening 21, not occopied by the bolt 16. If, for instance, the clip be employed on a truck having a coli an of less width thanthat shown in Figs 1 to l, the filler member 23 will be on the from that shown in Fig. l.

'" Not infrequently the brake supporting bracket on the column gets broken off.-

Formerly, in order to repair the truck, it

was necessary to replace the br'oken column at considerable time and expense. In Figs. 6 to 9 inclusive is shown a modified formof the anchoring device or 'clip that is provided with a brake support-ingbracket. lVith the use of this device, when the bracket is broken off it is only necessary to apply an anchoring device with a brake supporting bracket and reassemble the partswithout removing or replacing the column.

I As shown in Figs. 6 to 9 inclusive, the anchoring device or clip 25 is constructed similar to the clip shown in Figs. 1 to 5, except that it is provided with a depending angular flange '26 which is so constructedithat the sides 27 and 28 of said fiange willconforinto and engage two adjacent sides of I the column 13*. 28 of the depending flange 15 provided with The side a bracket 31 having the two spaced lugs 32 between which the brake supporting link 33 is adapted to be pivoted. The parts are so constructed that when the clip or anchoring device is in posit-ion on the truck, the bracket 31 will occupy substantially the same position as the corresponding brackets 8 in Fig. 1, whereby the brake 84-. will occupy its normal position.

In practice, if the columns 13 spread apart and the brake supporting bracket 8 is intact, the columns are straightened and the clips or anchoringv devices shown in 1 are employed. If, on the other hand the brake supporting bracket is broken oil the clip or anchoring device 25 shown in Figs. 6'to 9 isemployed.

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent tothose skilled in the art, and that various changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.
