RAILWAY-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 598,449, dated February 1, 1898. Application tiled July 23,1897. Serial No. 645,725 (No model.)

T @ZZ whom t may con/cern.-

VBe it known that I, JOHN TAYLOR, of Troy, in the county of Rensselaer and State of New York, haveinvented certain new and useful Improvements in Trucks; and I hereby declare that the following is a full, clear, and eX- act description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvementin trucks for electric railways; and it has especial refprovements.

- and spring-hangers.

erence to the connections between the truckframe and suspending springs and to certain other novel and useful details of construction and combinations of parts hereinafter described and claimed. Y

In the drawings, Figure l is a side elevation of a complete truck embodying my im- Fig. 2 is an enlarged vertical longitudinal section through one of the pedestals and connected part of frame, spring,

Fig. 3 is a detail transverse section on line 3 3, Fig. 2, looking toward the pedestal. Fig. 4 is a view of the hanger-casting detached'. Fig. 5 is a view of a slight modification of this casting. Fig. 6 is a vertical section on line 6 6, Fig. l, showing the center stay. Fig. 7 is a transverse section of the stay on line 7 7, Fig. 6. Figs. 8, 9, and l0 are detail views illustrating the connection of the motor-sustaining bar to the frame.

Referring to the drawings, A A designate the pedestals, whichare connected at top by parallel side bars B B, that are bolted to iianges o; of the pedestals, leaving a clear space therebetween for the accommodation of the inverted semi-elliptic springs C, which rest upon the axle-boxes D, while their outer ends are connected by links E to hanger-castings F, underlying the side bars B B, as shown. Each casting F is provided with side lips f f to embrace the outer edges of the opposite bars B and prevent it twisting or turning thereunder, and the inner lip f of the cast--l ing projects upward sufficiently to carry an inwardly-projecting-teat f2, Fig. 4, which is adapted to engage a recess or hole ein the inner side bar, so as .to uphold the casting and prevent longitudinal slip thereof on bars B. Instead of a teat]02 the lip may be secured in passing through a hole f2 in lip f',the teat being omitted. I prefer the teat, however, as the nut on the bolt is apt to work off or be sheared off and is more troublesome than the teat. Each casting is also provided with pairs of depending ears F', which are perforated for the passage of a transverse bolt G, which can be retained by a cotter g. The casting is, moreover, slotted, as at F3, between the ears for the accommodation of thelower ends of the pair of links E, which are hinged on bolt G, and their upper ends are loosely connected bya suitable bolt or rivet to the eye on the adjoining end of the spring O, as shown. Preferably the linksE are connected to the spring by stout countersunk rivets, so that the spring and links canv play vertically freely, butsnugly, between the side bars B B. It will be observed that the outermost ears F are directly under bars B B, so that the place by a countersunk or flush-sunk bolt f4,

principal lift or weight of the load is sustained from lateral vibration thereby, while free to expand and react according to the strains incident to usage. This construction has been tested and highly approved, because of its simplicity, ease of access, and interchangeability.

The lower ends of the legs of each pedestal A are connected by a bottom stay H, the ends of which fit into rabbets A in the legs and are retained by bolts h, dropped through vertical openings in the bottom webs of the legs, as shown. In the truck shown the weight of the car is carried at its extreme endshand consequently the braces and trusses tend to close the jaws of the pedestals upon each other and cramp the axle-boxes. This is overcome by the bottom stays I-I, arranged as shown and described. The inner leg of each pedestal is, moreover, provided with a lateral socket A2 for the reception of the end of a flat bottom bar J, which is set vertically edgewise, and an important feature is the fact that the socket A2 is so located that the bolt h can be dropped IOO in behind the socket and end of bar A, so that itcan be removed and replaced without disturbing bar A.

The bottom bar J and upper bars B B are rigidly connected by a center stay K, Fig. 7, the upper end of which is embraced between bars B Band lipped thereover and thereunder, as shown at la 7c', and its lower end is also lipped over and under bottom bar J, as shown at 7a2 k3, so that shearing of the securing-bolts K' K2 is absolutely prevented.

The motor-hanging bars L areV preferably connected to the bars J by means of anglebolts M, and the ends of bars L are reduced, as at L', and forged with eyes L2 for the passage of bolts M. The motors can be easily raised or lowered slightly in relation to the frame by simply turning bars L up or down, as shown in Figs. 8 and 10, respectively.

The other parts of the truck can be constructed as in some of my former patents- No. 1:32167, for instance-or in any desired m3111161.

It will be observed that the entire weight of the car-body is placedat the eXtreme ends of the truck, and consequently the weight of the car-body tends to force the pedestals toward each other and compress bars J longitudinally. The ends of said bars J are made square and accurately iitted into sockets A2 kof the pedestals and are held therein by the` compression due to the weight of the car-body, no bolts or other fastenin gs being required,

` because the pedestals tend to close upon the sides of the pedestal, having pairs of ears; and the links hinged to said castings by a bolt transiixing said ears; with the spring having eyes on its ends hinged'to the upper ends of said links, for the purpose and substantially as described.

2. The combination with the castings F having ears F' and lips f, f', substantially as described; of the links E connected to said castings, and the spring connected to said links, for the purpose and substantially as described.

3. The combination with the side bars of 55 the truck-frame, the inverted 'semi-elliptic spring located intermediate said bars, and the depending links swung from the ends of said spring; of the lipped castings F underlying said bars and provided with slots F2and ears F', and the bolt G transiixing said links and ears, for the purpose and substantially as described.

et. The combination of the parallelside bars B, B, and the hanger-castings F thereunder each providedwith upstanding flange f', having a teatf2, engaging an opening in one of the bars to retain the casting in place; with the spring, and the links connecting said' spring to said castings for the purpose and substantially as described.

5. The combination with the side bottom bars of a truck,` of motor-sustaining bars L having reduced ends L', and the angle-bolts M 'for securing said sustaining-bars to the bottom bars of the truck, for the purpose and substantially as described.

In testimony that I claim the foregoing as my own I aiiix my signature in presence of two witnesses.
