CAR-TRUCK.

Specification of Letters Patent.

Application filed August 27, 1908. Serial No. 450,406.

To all whom it may concern:

Be it known that 1, WILLIAM E. WooDAnn,

- The improvement claimed is hereinafter fully set forth.

ln the accompanying drawings: Figure 1 is a plan or top -view, partly 'in section, of a car truck embodying my invention; Fig. 2, a side view, in elevation, of the same; Fig. 3,, a-half transverse central section; and, Fig. 4, a half transverse section in the plane of one of the axles.

In the practice of my invention, I provide a truck frame having two side members, each of which isan integral metal plate, and comprises a top bar, 1, a bottom bar orpedestal tie bar, 1", and pedcstaljaws, 5, said side members being connected one to the other, on opposite sides of the transverse central plane of the truck, by two transoms, 2, which, in the instance shown, are of channel section, but may be of any other suitable and preferred form. to the side members through the intermediation of 'lilling castings, 3, the webs of which are bolted to the side members, and which have lateral flanges bolted to the transoms. The transoms and side members are also connected by gussots, 4, secured to them by vertical and horizontal bolts, the. connections being preferably, as shown, made through the intormediation of angles, 1", which serve, further, to stiil'en the side members.

Journal box guides or pedestal wear shoes, are bolted to the outer sides of each pair of pedestal jaws, 5, between which guides are iitted the journal boxes, 9, which inclose the bearings, S), for the journals, 8, of the axles, 8, on which the wheels, 7, of the truck, are secured. The journal box guides, extend through the openings between the pedestal jaws, and project from the outer sides there of practically throughout their entire width or transverse d1mens1on, their projection from the 111 nor sides of the side members be- The transoms are secured ing only for the slight extent which ivill suflice to enable the inner flanges of the j ournal boxes to clear them, and the frame side members, 1, are therefore located in vertical planes inside of, or nearer to the longitudinal central plane of the truck than, the vertical central planes of the journals, 8. The truck frame is movable vertically, relatively to the journal boxes, on which each of its side members is su ported by a single equalizer, 10. The equllizers, 10, are straight bars, of rectangular section, which extend longitudinally adjacent to the outer sides of the side members, 1, from one'of the journal boxes of each side member to the other, their vertical planes being in or near the vertical central planes of the journals, 8, and their ends resting on the tops of the journal boxes.

The side members are supported on the I equalizers through the intermediation of helical equalizer s rings, 11, which are coiled. around springro s, 12, suspended, at their upper ends, on, and depending from, the equalizers, said e ualizer springs abutting, at their lower en s, on spring seats, 12, fitted on the spring rods, and, at their upper ends, on spring sea-ts, 12 bolted to the adjacent side member, below the equalizer, through upwardly and downwardly extending lateral flanges.

A spring plank, 13, is suspended from the transoms, 2, by swing hangers, 14, journaled .on swing hanger pivots, 15, which are fitted in swing hanger pivot bearings, 16, on'the tops of the transoms. A swing bolster, 17, which, in this'instance, is shown as of U or channel section, and having its vertical members stiffened by angles, 17, but which may be of any other preferred form, is su )orted on the spring plank by semi-elliptic olster springs, 19, two pairs of which are interposed between the spriiw lank and seats, 17*, located near each of t 1e ends of the bolster. The webs of the filling castin s, 3, of the transoms, serve as end stops for t 1e bolster and wear plates for the adjacent ends thereof. Acenter casting, 20, and side bearings, 21, of the ordinary form, are secured to the bolster, at the middle and ends, respectively.

The form and relation of the side members and edestals above described are such aseto simp ify the construction and minimize the enabling single straight equalizers to be applied, instead of pairs of equalizers having upwardly bent ends, as heretofore employed, and, by reason of the frame construction used, necessary in, trucks of the M. C. B. type. The forgings for equalizers of the latter form are more complicated and diflicult to make, and are subject to the risk of injury in bending, from which the straight equalizers are entirely exempt.

I claim as my invention and desire to secure b Letters Paten In a car truck, the combination of two plate metal side frame members, having pairs of integral pedestal jaws adjacent to their ends, journal box guides fixed to and projecting, for the major portion of their transverse dimension, from the outer sides of the pedestal jaws, axles journaled in jour- .nal boxes fitting between said journal box guides, wheels fixed on said axles, transoms interposed between the side frame members on opposite sides of the transverse central plane of the truck, filling castings bolted to the side frame members and to the transoms between the ends of the latter, angle plates secured to the side frame members and extending from the transoms to the pedestal jaws, gussets secured to said angle plates and to the transon'is, single straight bar equalizers supported on the axles exterior to the side frame members, and equalizer springs interposed between and bearing on said equalizers and the side frame members.
