Ap ic t filed Oc 1 1. se e in 8.67.27

T all whom it may GOflGm;

Be it known that I, JoH G. BARBER, 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.

My present invention relates to car trucks, and is particularly designed as an improvement on the car trnck disclosed and claimed in my prior Patent No. 963,978, of date July 12, 1910.

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 with some parts removed and some parts broken away, showing the improved. car truck; Fig. 2 is a plan view with {some parts broken away and some parts sectioned showing one of the truck side frames and about one-half of the bolster illustrated in Fig. 1; Fig. 3 is a detail in perspective showing one of the so-called bolster cheek plates; and Fig. 4c is a view partly in elevation and partly in transverse vertical section, some parts broken away, showing the same elements that are illustrated in Figs. 1 and 2.

The truck wheels 1 are indicated in diagram only in Fig. 1.

The numeral 2 indicates the cast steel girder-type side frames shown as provided with journal box tie straps 3. The side frames 2 have laterally projecting brackets at on the opposite sides of the central webs thereof, and the said webs are provided with openings above said brackets, cut away to afford clearance for the projecting ends of transoms or cross tie bars 5, shown as of angle type, and having their flanges riveted to the said brackets a. Certain of the rivets 6, which connect the horizontal flanges of the brackets 4 to the horizontal flanges of the transoms 5, serve to center the lower ends of inner and outer pairs of coil bolster supporting springs 7 that rest upon the horizontal flanges of the said transoms. Seated directly upon the upper ends of the springs 7, are spring caps 8.

The numeral 9 indicates the lower me1nber of three lateral motion roller bearing" plates -9, 10 and 11, and this lower bearing plate is provided with four depending legs that rest directly, one upon each of the spring caps 8. The inner and outer pairs of legs straddle the upper flange of the cast side frames 2 and hold the bearing plate 9 against movement transversely of the truck, but permit free vertical movements of the same under yielding actions of the springs. Laterial motion bearing rollers 12 are inter posed between the bearing plates 9 and 10 and engage the customary self centering seats on the said members. The plate 10 is shown as secured by rivets to the end portions of the Web of a truck bolster, the main body portion of which is made from a heavy I-beam 13. The plate 11 is placed upon the web of the said bolster and is also preferably secured thereto by rivets. The said plate 11 006 )erates with a top plate 14 and interposed rollers 15, to afford the side bearings or radial motion anti-friction devices of the truck. The bolster 13, as shown, is provided with a centrally located sleeve 16 that serves as one of the members of the center bearing, not completely shown.

The construction so far described is substantially that of my said prior patent above identified. In the present truck, however, the bolster is formed from commercial rolled steelI-beamwhich does not, for pro er strength, require as great width as the istance between bolster columns or bolster guiding lugs, Hence, the end portions of this bolster'13 are widened out or expanded by the applicant, to both sides thereof by so-called ,oheek plates 17, which are preferably steel castings secured to the flanges of a main body or beam 13 of the bolster, by means of rivets. These cheek plates 17 work between heavy bolster guiding lugs or columns 18, preferably cast integral on the side frames 2, but their flat projected faces 100 directly engage with the flat vertical faces of chafing plates 19, that are directly appliedto the opposing faces of the said lugs 18. These chafing plates 19 are preferably flanged so that they embrace the sides of the 105 detachably secured to the column lugs 18, 110 I which, by a single nut-equipped bolt 21 applied therethrough, has been shown in Figs. 2 and 4.

The cheek plates 17, inside of the truck side frames, are formed with strong laterally projecting stop lugs 22 that are engageable with stop shoulders 23 on the hanger brackets 19, to limit the endwise movements of the truck bolster transversely of the truck. Also, these lugs 22 work under horizontally extended laterally projecting stop flanges 24 formed on the said hanger brackets 20. The engagement of the upper extremities of the lugs 22 with the said stop flanges 24 limits the upward movements of the truck bolster when the load is removed, under the action of the springs 7. The said lugs 22, therefore, act as stop lugs to limit both the endwise movements of the bolster and the upward vertical movements thereof. The cheek plates 17, when riveted to the bolster, become a rigid part thereof, and in some instances, they might be integrally formed with the bolster, which may be cast or otherwise formed. However, there is an advantage in independently constructing the same, in that when worn out, they may be replaced by others. Also, it enables the said cheek plates to be made of a harder or otherwise different material than the main body of the bolster, also the chafing plates 19, when applied to the column lugs 18 become a rigid part thereof, which, in some instances, might be formed integral therewith, but are preferably separately formed.

What I claim is:

1. In a car truck, the combination with truck side frames having bolster guiding columns comprising bolster lugs and separately formed chafing plates rigidly secured thereto, of a bolster yieldingly supported on said frame with freedom for vertical and endwise movements transversely of the truck, said bolster having lugs, each of which engages two stops on the chafing plates of said columns, the engagement with one serving to limit the endwise movements of the bolster, and the engagement with the other serving to limit the vertical rising movement of said bolster.

2. In a car truck, the combination with truck side frames having bolster guiding columns comprising integral column lugs and separately formed chafing plates rigidly secured thereto, said chafing plates having extensions affording hanger brackets, the said hanger brackets having stop flan es and stop shoulders, of a bolster yielding ly supported on said side frames with freedom for vertical and endwise movements, said bolster having stop lugs that are engageable with the stop shoulders of said hanger brackets to limit the endwise movements of said bolster, and are engageable with the stop flanges of said brackets to limit the vertical rising movement of said bolster.

In a car truck, the combination with truck side frames having bolster guiding columns comprising integral column lugs and separately formed chafing plates rigidly secured thereto, said chafing plates having extensions affording hanger brackets, the said hanger brackets having stop flanges and stop shoulders, of a bolster yieldingly supported on said side frames with freedom for vertical and endwise movements, said bolster having separately formed rigidly secured cheek plates applied to the sides of its ends and formed with projecting stop lugs that are engageable with the stop shoulders of said brackets to limit the endwise movement of said bolster and are engageable with the stop flanges of said brackets to limit the vertical rising movements of said bolster.

at. In a car truck, the combination with truck side frames having bolster guiding columns comprising integral column lugs and separately formed chafing plates rigidly secured thereto, said chafing plates having extensions affording hanger brackets, the said hanger brackets having stop flanges and stop shoulders, of a truck bolster, the body of which is formed from a commercial I-beam, and is provided at its ends with. laterally projecting, separately formed cheek plates rigidly secured to the flanges thereof by rivets, and provided with outwardly projecting stop lugs that are engageble with the stop shoulders of said brackets to limit the endwise movements of said bolster, and are engageable with the stop flanges thereof to limit the rising movement of said bolster.

In testimony whereof I aliix my signature in presence of two witnesses.
