RAILWAY CAR Filed May 17, 1944 2 sheets-sheet 2 Patented Nov. 5, 1946 RAILWAY CAR Charles L. Heater, Chicago, Ill., assignor to American Steel Foundries, Chicago, Ill., a corporation of New Jersey Application May 17, 1944, Serial No. 535,911

(Cl. S-222) 1o claims. 1

'My invention relates to railway cars and more particularlyto a novel suspension therefor.

The general object of my invention is to devise an arrangement in which the car body is resiliently supported directly from each wheel and axle assembly without the' use oi aconventional truck. In this manner I am enabled to use any desired number of wheel and axle assemblies by eliminating the trucks, each of which customarily 'comprises two assemblies.

The specic object of my invention is to design a railway car in which the car body comprises one or more transverse bolsters, each end of the bolster being rigidly secured to a pedestal casting comprising spaced hollow depending pedestal legs receiving therebetween a journal box carrying resilient means housed within said legs and aording support for the car body.

Another object of my invention is to provide in an arrangement such as above described a spring hanger roekably mounted on each journal box and aioiding a support for thecar supporting reesilent means.

In the drawings,

Figure l is a fragmentary side elevation of one end of a railway car embodying my invention, only one wheel and axle assembly being shown, inasmuch as the connection of each assembly to the car body is susbtantially identical.

Figure 2 is a fragmentary top plan view of the structure shown in Figure l, only one side of the car being illustrated, inasmuch as it is symmetrical about its longitudinal center line.

Figure 3 is a fragmentary sectional view taken in the transverse vertical plane indicated by the line 3--3 of Figure 1.

Describing my invention in detail, the car body comprises at each side thereof a side sill 2 connected at each end thereof to an end sill 4. The bolster 6 extends transversely of the car and is connected at each end thereof to the adjacent side sill, said bolster being connected intermediate its ends to the center sill l, Intermediate sills or floor supports 8, B extend between the bolster 6 and the end sill 4.

A pedestal casting generally designated I6 is rigidly connected as by rivets at I2, I2 to the body bolster 6, said casting comprising the spaced depending hollow pedestal legs I4, I4 dening therebetween a pedestal opening I6 (Figure 1), within which is received a journal box I8.

The journal box comprises an arcuate surface (Figure 3) on the top thereof affording a rockable seat for a generally U-shaped swing hanger 2, the spaceddependingarms 24, 24 of which 55 are provided with slots 26, 26 adjacent their lower extremities for the reception of a bar 28 which supports spring seats or support members 30, 30 slidably seated within respective legs I4, I4 for vertical reciprocation therewithin, each of said spring seats 36, 36 being formed with upstanding flanges 3l, 3i (Figure 1) affording positioning means for a spring 32 mounted on the seat 30, said spring bearing at its upper extremity against the horizontal web 34 integrally formed within the pedestal leg I4.

The journal box is provided at each side thereof with inboard and outboard grooved anges 36 and 38 for the reception of a wear plate 40, said plate dening with the adjacent side of the box a space within which the hanger 22 may swing, as hereinafter described, and each leg is provided with a wear plate or liner 42 for slidable cooperation with the adjacent plate 40. The journal box is provided on its outboard end with a hinge lug di. for pivotal support of an associated cover or lid, as will be clearly understood by those skilled in the art, and adjacent its inboard end the box is provided with an upstanding lug 46 (Figure 3) to which is connected by a bolt and nut assembly 4l the transverse member 48 of a substantially rectangular brake frame 50, formed and arranged, as will be clearly understood by those skilled in the art, -for the support of brake gear for the wheel and axle assembly 52, each end of which is mounted within the associated box i8 by means of a conventional bearing 54 and a bearing 'wedge 56 (Figure 3).

It will be understood that while the journal box I8 herein illustrated is of the conventional friction type utilizing a brass friction bearing 54 for cooperation with the wheel and axle assembly if desired any suitable roller bearing journal box assembly may be utilized.

it may be noted that because of the diagonal plane in which the swing hanger 22 is disposed in its normal position, as seen in Figure 3, a force is applied to the journal box tending to push it in an outboard direction off the axle of the asT sembly 52 and this force is resisted by the brake frame 5d, which is a substantially rigid rectangustructure connected at each end thereof to the associated journal box by the before-mentioned bolt and nut assembly fil and by the spaced bolt and nut assemblies 56, 58 (Figure 2).

The bar 28 is vertically reciprocable adjacent each extremity thereof within a slot 6) formed in the adjacent wall of .thehollow pedestal leg I4; and each extremity of -thebar is adapted for abutmentwith the adjacent surface (Figure 1) vof the spring seat 30, thereby maintaining said bar in assembled relationship. It will be understood that the slots 60, Bl] permit relative vertical movement between the pedestal casting i9 and the bar 23 as the car body oscillates on the springs 32, 32; however, the slots 60, B prevent relative movement between the pedestal casting and the bar 28, thus causing a rocking action of the swing hanger A22on the arcuate surface 2t of the journal box during such lateral movement. In this connection it may be noted that each slot 2t, as seen in Figure 3, is widened at its upper extremity to aiord limited pivotal movement of the bar 28 therein during swinging movement of the hanger 22. It may also be noted that, inasmuch as each hanger 22 is normally disposed in a diagonal plane inclined downwardly and outwardly of the car, lateral movement of the car in either direction causes a slight tipping or .tilting action thereof in response to the tilting of the opposed swing hangers 22, 22 at opposite ends of the wheel and axle assembly 32.

It will be understood that in my novel arrangement any desired number of wheel and axle assemblies 52, 52, within reason may be utilized in a single car, inasmuch as each wheel and axle assembly is afforded an independent connection to the car body.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown which is merely by way of illustration and not limitation as various 'and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
