. T0 aZZ whom it may concern:

Be it known that I, WILLIAM L. AUSTIN, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Railway-Oars, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part hereof.

This invention relates to the means of suspension or support of the bodies of railwaycars upon or with relation to the trucks. I-Ieretofore it has been usual to support the car-body by a center-pin under thecar,-resting upon a corresponding center-plate on the top of the truck. In cars in which a considerable weight is to be carried, while at the same time easy riding of the car-body is desired, as in combination steam-motor cars, in which the weight of the boiler and engine to be carried is considerable,.the objections to the supporting of the Weight .upon the floor of the car-body and the supporting of the carbody upon the truck in.the manner just referred to become very clearly apparent. The jars and vibrations of the car-body are increased, by reason of the great weight of the boiler and engine supported by the floor of thecar-body, to suchan extent as to interfere materially with the easy riding 'ofthe carbody, and by reason of the considerable friction between the truck and the car-body the truck does not swivel easily as the car passes curves.

The main object in View in this invention has been to improve the means of support or suspension of the car-body upon or with relation to the truck in such a manner as to overcome the difiiculties above alluded to.

The improvements have been designed with especial reference to their application to combinationsteam-motor cars, but are neverthe less applicable to cars of other types.

The invention will be more fully described hereinafter with reference to the accompanying drawings, in which convenient andpractical embodiments of the invention are illus trated for the purpose of enabling the nature of the said invention to be more'clearly understood.

In the drawings, Figure 1 is a View in side elevation of a structure which embodies the tion is concerned, except as may be indicated hereinafter, and it is therefore unnecessary to illustrate or describe the same in detail.

In Figs. 1 and. 5 of the drawings the floor of a car-body is indicated at A, and at B in Fig. 1 is represented in part a truck-frame,

which is provided with wheels b b in the usual manner. ..The vertical support, to which referenceis made hereinafter, rests upon and is carried by the truck-frame. I The structure shown in Figs. 1, 2, 3, and 4 of the drawings comprises a plateO, which rests upon the truck-frame and is provided with a vertical flange or collar D to form a seat for the boiler, which is indicated at E, and which in the present instance constitutes the support from which the car-body is suspended, the said boiler projecting through and above the floor of the car-body. A plate F in the structure shown is secured to the floor of the car-body in such manner as to carry the weight of the car-body and is provided with a flange .or

collar G, which fits around the support or of which are indicated in the drawings, each suspension rod or hanger being connected to the support E at one end and to the plate F or floor of the car-body at the other end. For convenience of attachment a suspension pad or bracket I is secured to the support or boiler E for each hanger H, the hanger passing through the bracket and having above the same a nut or nuts h, by means of which the length of each hanger can be adjusted easily. To provide for easy riding of the carbody and also for automatic adjustment'of the hanger as required by variations in the track, a spring h may be interposed between each hanger and its bracket, being shown in the drawings as a spiral spring resting upon the bracket, with a washer k interposed between v the nuts 72 and the upper end of the spring. As it is obvious that the swiveling of the truck with reference to the car-body as the car passes curves will deflect the hangers more or less from the vertical, a ball-joint bearing 7L3 is provided at each end of each hanger, one below the plate F and the other above the bracket 1, to allow for such swiveling.

In the arrangement illustrated in Fig. 5 the plate or ring 0, which rests upon the truck-frame and carries the boiler E, constitutes the support from which the car-body is suspended. A plate F is arranged to carry the weight of the car-body, substantially as described above, and is also provided with a flangeor collar G, which fits around the support, as before. Brackets I depend from the plate F for engagement with the lower ends of the suspension rods or hangers H, which are carried by the plate or ring G, nuts h, springs h, washers h and ball-joint hearing, 7? being employed by preference, as already described with reference to Figs. 1, 2, 3, and 4. The functions of the several parts included in the arrangement just described are substantially the same as the functions of the corresponding parts in the construction shown in Figs. 1,2, 3', and 4 and do not require further explanation herein.

It will now be readily understood that with a construction such as those already described the car-body is relieved entirely of the weight of the boiler and engine or other heavy parts which are supported directly upon the truck and that as a consequence the car-body will bethe easier riding. Moreover, as the weight of such parts is supported directly by the truck, while the weight of the car-body is suspended by the hangers, there will be no friction due to weight between the center-plate of the truck and the car-body and the truck will therefore swivel freely. There can be no side-swinging motion of the truck with reference to the car-body, as the flange or collar G and the cooperating part which is supported on and secured to the truck guide and cenprecise construction herein shown.

I claim as my invention- 1. In a'railway-car, the combination of a car-body, a truck swiveled upon a central guide, and suspension-hangers connected to said central guide and to the floor of the carbody and by which said body is supported from said truck.

2. In a railway-car, the combination of a oar-body, a truck, a support resting centrally upon said truck and projecting through and above the floor of the car-body and suspension-hangers connected at their upper ends to said support and carrying the car-bod y at their lower ends.

3. In'a railway-car, the combination of a car-body, a truck, a support resting centrally upon said truck and projecting through and above the floor of the car-body, suspensionhangers connected at their upper ends to said support and carrying the car-body at their lower ends, and springs interposed between said hangers and the support.

4. In a railway-car, the combination of a car-body, a truck, a support resting centrally upon said truck, suspension -hangers connected to said support and carrying the carbody, and ball-joint bearings interposed between the support and the hangers and be- Ltween the hangers and the car-body.

5. In a railway-car, the combination of a car-body, a truck, a support resting on said truck, a plate secured to the car-body and having a collar to fiti about the support, sus- 1 pension-hangers connected at their upper ends to said supportand at their lower ends to said plate, the contact-surface of said co1-. lar being rounded.

6. In a railway-car, the combination of a car-body, a truck, a boiler resting on said truck, and suspension-hangers connected to said boiler and carrying the car-body.

'7. In a railway-car, the combination of a car-body, a truck, a boiler resting on said truck, suspension-brackets secured to said boiler, and suspension-hangers connected to said brackets and supporting the car-body at their lower ends.

This specification signed and witnessed this day of March, A. D. 1898.
