Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed June 16, 1909. Serial No. 502,510.

To all whom it may concern:

Be it known that I, JOSIAH H. SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Suspension-Railway-Car Frames and Supporting-Trucks Therefor, of which the following is a specification.

My invention relates to an improved construction of car frame, and improved construction of car trucks especially adapted for operation with the improved construction of car frame.

A further object is to provide an improved car frame having longitudinal roof beam sections arched or bowed upwardly at points adjacent the ends of the car frame, and supporting the car upon bowed springs, the latter secured pivotally to the trucks.

A further objectis to provide an improved car frame with an arched longitudinal beam or beams elastically supported upon improved trucks especially constructed and adapted to receive said arched beams, and which will permit of slight lateral movement of the car frame, and slight vertical movement of the car frame, but prevent separation of the car frame from the trucks, even though the springs or their pivotal supporting devices become broken.

A further object is to provide an improved construction of suspension railway car frame and car trucks supporting the same, that will permit the car the necessary movement in the ordinary operation of a railroad of this kind, but which provides safety devices, which come into operation in the event of injury to normally operating parts, so as to preclude any possibility of a separation of the car from its trucks.

A further object is to provide an improved construction of car frame, composed entirely of metal, and the several bars and plates constituting said frame being securely tied together, whereby an extremely strong and well braced structure is secured, and one enabling a car to be made attractive and ornamental in appearance, and yet capable of withstanding the greatest of strains and stresses, and practically rendering it impossible for one car to telescope another in the event of a collision, as the car is strengthened throughout, above and below by longitudinal bars or girders, and above and below by transverse bars or girders rigidly secured to the longitudinal bars or girders, and effecting a frame work tied securely in all directions, and resulting in a car of maximum strength and durability.

WVith these and other objects in view, the invention consists in certain novel features of construction, and combinations, and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a view in side elevation illustrating my improvements. Fig. 2, is an enlarged view partly in elevation and partly in section showing one end of the car frame and its supporting truck. Fig. 3, is a view in cross section through the car frame, and partly in section and partly in end elevation of the truck illustrating the structure of the truck, and the manner of supporting a car thereon. Fig. l, is a top plan view of the car frame. Fig. 5, is a view in horizontal section taken on the line 5-5 of Fig. l, and Fig. 6, is an enlarged fragmentary view in horizontal section showing a portion of the front end and corner of the frame taken at the same position as the section 5.

l, 1, represent the side frames of the truck, having yokes 2 secured at their ends, and elastically supported upon the journal boxes 3 by means of coiled springs 4.

5 represents the axles fixed to wheels 6, the latter adapted to run upon any approved suspension railway structure. The trucks are precisely alike, and the following description of one will of course apply alike to both.

To the inner face of the side frames 1, angle bars 7 are securely riveted, and cross channel bars 8 are secured at their ends to the angle bars 7 as shown, and a casting 9 is secured to these cross channels 8 at the center of the truck, and is provided with a socket to receive a journal 10 on a block 10 having depending flanges 10 at its ends, for a purpose which will more fully hereinafter appear.

The side frames 1 are made with downwardly projecting extensions 11, which are connected by parallel channel bars 12, the latter secured at their ends to the side frame extensions 11 by means of angle brackets 13 securely riveted to the frame and the channel bars 12. their ends, support brackets 14, and the latter provide bearings for pins 15, on which depending links 16 are pivotally supported. There are two pairs of these links at both ends of channel bars 12, and the links of each pair are connected by cross pins 17, on which nested bow springs 18 are secured, and project at their center through an opening 19 in a pocket block 20, supporting the block, and the latter is adapted to move vertically between bars 12, but is enlarged at its upper end as shown at 21, to limit the downward movement of the pocket. This block 20 is adapted to receive a depending journal 22 on a pillow block or casting 23, said block 23 is provided at its sides with upwardly projecting flanges 24; corresponding with the depending flanges 10 of bracket 9, and said flanges 10 and 2 1 secured to parallel arched channel bars 25, strengthened by plates 26 and 27 at the sides and bottom respectively, forming in effect, an arched longitudinal girder or beam of the car frame, as will be hereinafter pointed out more in detail. These longitudinal arched beam or girder sections are secured at their ends by angle brackets 28 with transverse girders 29 in the upper portion of the car frame. There are four of these main transverse girders, which are heavier and longer than the others, being made up of plates and angles as illus trated, and at points between these main girders 29, shorter and lighter transverse girders 30 are located as illustrated. These main transverse girders are connected by gusset plates 31 with longitudinal angle bars 32, and with vertical posts or columns 33, and the lower ends of these columns 33 are connected by gusset plates 34 with longitudinal channel bars 35 of the floor frame.

The longitudinal bars 32 and the outside longitudinal bars 35 of the floor frame are connected at regular intervals by posts or columns 36, and a plate 37 is secured to all of these posts at the side of the car, and extends from the lower edge of the car to a point about midway the height of the side of the frame, so as to provide a series of window spaces between the bar 32, the upper edge of plate 37, and the posts or columns 33 and 36. This plate is strengthened at its upper edge by means of angle bars 38 and 39, and by inclined sill plates 4:0, and con stitutes in effect a longitudinal girder, which adds materially to strengthen the frame.

The top portion of the car frame is given a shape such as ordinarily given to passenger coaches, to provide a series of ventilator spaces tl. The ends of the car frame are formed by parallel curved upper and lower channel bars 42 and 4-3 respectively, secured by the forward gusset plates 31 to the bars 32 and 37 and posts or columns 33, and are These channel bars 12, near braced and strengthened by vertical bars 14 and plates 45 as clearly illustrated, particularly in Fig. 3.

The floor frame as shown most clearly in Fig. 5, comprises the bars 35 and bars 16 parallel therewith, extending throughout the length of the car frame. These longitudinal bars 35 and 46 are braced and strengthened by lateral bars 47, located at suitable intervals throughout the frame. The posts or columns 14 at the ends of the car frame are slightly curved in cross section as shown most clearly in Fig. 6, to give to the car a neat and finished appearance, and dispenses with sharp angles at the corners of the structure. This Fig. 6, also illustrates a window frame as, secured to the posts or columns 44, and a front plate a5, which is secured to the columns or posts and the bars 42 and 43, and cut out to form window openings 50, and leaving door openings 51 at the sides and both ends of the car as shown in Figs. 2 and 3. lVith a car frame of this character, it will be noted that the longitudinal beam sections 25, which are connected to the main transverse girders 29, and the latter connected by gusset plates 31 with the vertical columns or posts 33, and these latter to the floor frame, insure an extremely strong frame work, which with the parts above described, constitute, in effect, cradles, whereby the entire weight of the car is supported upon the arched longitudinal beam sections 25, and these latter are supported upon pillow block These pillow blocks 22 are mounted in the pockets 20, and the latter are supported upon the springs 18, so as to elastically support the car and allow it vertical movement within certain limits. A. little vertical movement is desirable, but only such as to provide a slight cushioning action to take up vibrations, but this movement must be very slight, and it will be observed that bracket 9 will limit the upward movement of girder 25, while the contact of block 29 with cross bars 12 will limit the downward movement.

It will further be observed that as the springs 18 are supported at their ends upon hanging or pivoted links 16, the spring is permitted to bow and straighten, the contraction and expansion of the ends of the springs toward or away from each other being compensated for by the pivoted links. If one of these links or the spring at one end should become broken or disconnected, the pocket 20 would be supported directly upon the cross girders 12, and there could be no possibility of the car separating from the truck and falling to the ground. In fact, it will be observed particularly by reference to Fig. 2, that in order for the car to leave the truck, it would be necessary for the longitudinal girder to break through the bars 12, in addition to some breakage in the spring or its supporting links, and as these bars 12 are short and may be made of any desired strength, it can be readily understood that a structure of this kind would be extremely safe.

Emergency wheels 52 are revolubly connected to the outside of the truck side frames, and are disposed so as normally not to engage the rails of the track, but are positioned slightly above the rails, so that in the event of the breakage of an axle or a truck wheel, these auxiliary wheels will come into action and ride upon the rails to prevent tumbling of the trucks.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.
