. UNITE EDWARD POSSON, OF CHICAGO, ILLINOIS.

CAR-TRUCK.

To all whom it may concern:

Be it known that I, EDWARD POSSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Generally stated, this invent-ion relates to and has for its object to improve the construction of car trucks, and to such ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

More particularly and specifically stated, my invention is directed to the improvement of truck side frames of the arch bar type, and. has for its object the elimination of castings and of bolts in the side frame proper, and a resulting increased strength and durability in the completed truck frame.

These objects and others are accomplished in the improved truck, the preferred embodiment of which is illustrated in the accompanying drawings. In this preferred form of the truck frame, no castings are employed, pressed steel or wrought iron elements being substituted therefor. All of these parts are rigidly connected by rivets, and all bolts are eliminated from the side frame proper, the only bolts employed in connection therewith being the journal box bolts.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation showing a truck frame designed in accordance with my invention; Fig. 2 is a plan view showing one side of the truck frame; Fig. 8 is a fragmentary view in perspective, some parts being sectioned on the line 02 m on Fig. 1; Fi 4 is a fragmentary view in perspective, some parts being sectioned approximately on the line 50* as" on Fig. 1; and Fig. 5 is a fragmentary view in perspective, some parts be- Specification of Letters Patent.

ing sectioned approximately on the line as w on Fig, 3.

The numerals 1 and 2 indicate, respectively, the top and bottom arch bars, the numeral 3 the journal boxes and the nume 'al 4 the wheels of a truck of the arch bar type. Tie straps 5 are riveted at their inner ends to the bottom arch bar .2 and are extended under the journal boxes. Customary journal box bolts (3 are used to clamp the journal boxes to the overlapping endsof the arch bars 1 and 2, and to the undcrlyil'ig ends of the tie straps 5.

In place of the usual cast columns, I employ steel or wrought iron columns 7 that are pressed or rolled into channel form, and at their upper and lower ends are lapped or bent around the top and bottom arch bars,

respectively, so that, preferably, they completely embrace the same. The best possible connection between the sand columns and arch bars is made as follows: The upper ends of the columns 7 are slit at their angles (these slits being preferably made before the columns are bent into channel form), and the upper ends of their webs or intermediate portions are turned backward to form flanges 8 that bear directly against the inner surface of the top arch bar 1. The extended upper ends 9 of the side flanges of the said columns are then bent, one over the other and over the top of the arch bar 1, so that they tightly embrace the said top arch bar. Very much the same thing is done at the lower ends of the columns, that is, they are slit at their angles, (preferably before the columns are bent into channel form) and the lower ends of their webs are turned backward to form foot flanges 10 that rest directly upon the upper surface of the bot tom arch bar 2, and the lower ends 11 of the side flanges of said columns are bent, one over the other, and lapped around and under the said bottom arch bar in close contact therewith. Rivets 12 are passed through the top flange 8, through the top arch bar 1, and through the overlapped upper ends 9, and other rivets 1.3 are passed through the extended ends of the said flanges 8 and through the top arch bar. Rivets 14: are passed through the foot flange 10, through the bottom arch bar 2 and through the over lapped lower ends 11 of the columns. The lower ends of the columns 7 are preferably offset outwardly at 7 for a purpose which will presently appear. Channel -shaped pressed steel or wrought iron column bases 15, are seated on that portion of the bottom arch bar 2 that extends between the columns, and the webs of the upturned ends of-these column bases engage directly with the faces of the offset lower portions of the said columns. Angle iron or steel cross transoms 16 are seated in the angles of the column base 15 and rivets 17 are passed through their horizontal flanges, through the said column base and through the bottom arch bar 2.

Chafing plates 18, pressed or rolled into channel shape, are placed on the inner faces of the columns 7 and are secured thereto by rivets 19. The side flanges are cut ofl from the lower ends of these chafing plates 18 and these depending ends are overlapped with the vertical flanges of the angle transoms 16. Centrally located rivets 20 are passed through the lower ends of the chafing plates 18, through the upturned flanges of the angle transom 16, through the upturned ends of the column base 10, and through the webs of the cooperating columns 7, thus rigidly uniting the said parts. Other rivets 21 are passed through the lower outer edges of the said chafing plates, through the upturned flanges of the angle transom 16 and through the webs of the upturned ends of the said column base 10. Here, it may be noted that the columns 7 are but slightly wider than the arch bars 1 and 2, being only sufficiently widened to cause the vertical flanges thereof to straddle the said arch bars. The column bases 10 and the chafing plates 18 are preferably of the same width and both are considerably wider than the said columns. The upper ends of the rivets 17 are preferably countersunk into the horizontal flanges of the angle transom 16 so as to afford a smooth bearing for the spring bases, not shown. Also, the inner ends of the rivets 19 are preferably countersunk into the faces of the chafing plates 18, so as to afford smooth bearing surfaces for the truck bolster, not shown. Secured to the upper portions of the inner flanges of the chafing plates 18, are break hanger brackets 22, shown as formed by steel or wrought iron plates bent into channel-shape form. The inner and outer flanges of these hanger brackets 22, and the inner flanges of the chafing plates 18, to which they are riveted, are provided with alined perforations 23 through which a bolt pin may be passed to attach the break hanger links.

The arch bar truck frame illustrated is of the Master Car Builders type, but so far as my invention is concerned, may be much altered. I believe it to be broadly new and desire to claim broadly any kind of a truck frame in which columns are provided with end flanges or portions bent to embrace the arch bars and thereby interlocking the said columns and arch bars independently of rivets. The rivets are, of course, necessary to give the desired strength and rigidity, but additional and independent strength is given by lapping the ends of the columns with the arch bars. Also, the manner of forming and connecting the column bases to the columns, to the lower arch bar,'and to the transoms, is considered broadly new. Further, novelty is added by the application of the chafing plates and the manner of connecting the same to the columns, cross transoms and column bases. This arrangement gives a maximum load carrying capacity in the truck frame with a minimum of material, and at the lowest possible cost of construction. In the truck side frames proper, there are no bolts, and hence, no joints that can work loose, and the rivets, when properly applied, connect the truck elements as rigidly as if they were integrally united. The channel-shaped column bases, in addition to other functions, prevent the load from deflecting the bottom arch bar between columns, and they also aflo-rd a wide base to which the angle transom may be riveted.

One object of this invention is the provision of a multi-part pressed steel or wrought iron truck frame to displace steel castings. These side frames, complete, ex cept the journal boxes, or with the journal boxes applied for that matter, but without the transoms applied, can be built and shipped, and the cross transoms applied at the place and by the persons completing the erection of the trucks.
