TRUCK.

SPECIFICATION forming part of Letters Patent N o. 72? 618, dated" May 12, hiApplication filed m 9,1902. Seri l No. 106,652. (No model.)

T0 at whom it may concern;

Be it known that I, JOHN M. HANSEN, a resident of Pittsburg, in the county of Allegheny.

and State of Pennsylvania, have invented'a new and useful Improvement inTrucks; and

I do hereby declare the followingtobe a full, clear, and exact description thereof.

My invention relates to trucks for railwaycars, and more especially to trucks of the diamond-frame type.

The object of my invention is to improve trucks of this character in details of construction,which are hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan View of myimproved truck. Fig. 2 is a side elevation thereof. Fig. 3 is a. transverse vertical section of the same. "Fig. 4 is a transverse vertical section of one side frame on the line 4 4,Fig. 2; and Fig. 5 is a horizontal section on' theline 5 5, Fig. 2.

My truck-frame comprises top and bottom arch-bars, tie-bars, columns, journal-boxes, and the like. The top arch-bar lis'of inverted-trough shape, having laterally-project; ing flanges 20f suitable width on its lower side. Thisiarch-bar may either have its ends open or else have them closed or boxedin, as-

shown in Fig. 2. The lower arch-bar 3 preferably is of rectangular cross-section and in general may be of the shape usually employed for members of this kind. The arch-bars are united by rivets 4 at their outer en ds and diverge from each other toward their centers. The tie-bars 4 may be of any-preferred form, preferably of rectangular cross-section, and,

are united to the lower arch-bars near their centers, while their ends are separated from the lower arch-bars to receive the journalboxes 6 therebetween. may be of any suitable or preferred construction.

These journal-boxes- They are separated from the arch-bars by meansof the liners 7, which lie between Between the top and bottom arch-bars, near their middle portions, are the columns 10, which are formed of pressed steel plates, having their vertical portions trough-shaped, as shown, and provided with laterally-projecting fla'nges 11 on their sides. The upper ends of these columns are suitably flanged, as shown at 12, for riveting to the flanges of the top arch-bars. The lower ends of the columns are bent to form the flange 13, through which they are secured to the lower arch-bar. Oolumn liners 14, formed of bent or pressed metal plates, are riveted to the inner faces of the columns and have their bent ends lying, respectively, underneath'the top arch-bar and above the lower arch-bar. These} liners are formed of quite wide plates and project inwardly a considerable'distance inside of the from side frame to side frame, being'riveted tothe side frames and-lying abovethe in- ;turned endsof the columns andliner plates.

This spring-plank supports the, usual sprin gs 17, upon which 'reststhe truck-bolster 18. This bolster may be of any preferred or desired construction and is provided'with the chafing-castings 19, which bear against wearing-plates 20, formed of rectangular pieces of plate metal attached to the inner faces of the column-liners. Riveted to the lower flanges of the topLarch-bar and lying between the inturned upper ends of the column-liners is a plate 21, which projects inwardly, as shown, and has its inner end flanged to present a bearing-surface of proper size to distribute the side thrust, said plate being adapted to come in contact with: the truck side bearing 22, attached to the bolster, and limit the sidewise movement of the bolster.

The truck will of course be provided with the usual brake mechanism; but, this forms no part of the present invention, and therefore will not be described. The particular form of brake mechanism shown in theg'drawings is intended to be illustrative merely.

The truck side frame described is very simple and strong. All of the parts are so formed that the rivets pass through outwardly-projecting flanges or the like, so that hand-riveting is avoided, thus making it easy and expeditious to assemble the same.

\Vhat I claim is- 1. In a car-truck, thecombination of side frames composed of top and bottom arch-bars, two separate column-posts having theirends flanged and riveted to said top and bottom arch-bars, said column-posts having their vertical portions trough-shaped, a springplank overlapping the lower flanges of the column-posts and secured to the bottom archbars and uniting the side frames, and a bolster having its ends projecting between the columns and underneath the top arch-bars.

2. In a car-truck side frame, the combination with top and bottom arch-bars, of two separate column-posts provided with flanges at their upper and lower ends for riveting to the top and bottom arch-bars, said columnposts having their vertical portions troughshaped and provided with laterally-projecting flanges, and column-liners applied to the inside faces of said colu m n-posts and secured to the flanges thereof, said column-liners having their top and bottom ends bent inwardly and lying respectively below the top arch-bar and above the lower arch-bar.

In a car-truck side frame, the combina tion with a top arch-bar of inverted-trough shape and provided with laterally-projecting flanges, of a bottom arch-bar riveted to said top arch -bar near its ends and diverging therefrom at its middle, and column-posts interposed between said top and bottom archbars and having their ends flanged and riveted thereto, said column-posts having their vertical portions trough-shaped and provided with laterally-projecting flanges.

4C. In a car-truck side frame, the combination with top and bottom arch-bars united near their extremities and diverging at their centers, of column-posts interposed between the diverging portions of said arch-bars, column-liners applied to the inner faces of the columns and projecting inwardly beyond the truck-frame, and brake-beam hanger-brackets riveted to said column-liners.

5. In a car-truck, the combination with a bolster provided with a shoulder, of a truck side frame comprising top and bottom archbars, column-posts interposed between said arch-bars, and a stop-plate secured to the top arch-bar between the column-posts and projecting inwardly and having its inner end lying in proximity to the shoulder on the bolster.

In testimony whereof I, the said JOHN 1V HANSEN, have hereunto set my hand.

JOHN M. HANSEN. IVitnesses:

A. B. FRASER, WM. BIRRMAN.
