JOHN TAYLOR, OF TROY, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 674,224, dated May 14, 1901. Application tiled February l, 1901. Serial No. 45,636. (No model.:
T0 @ZZ whom, t may concern.'
Beit known that I, JOHN TAYLOR, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Trucks; and I hereby declare that the following is a full, clear, and
exact description thereof, reference being had to the accompanying drawings, which form part of this specification.
This invention is an improvement in what are .known as short-wheel-base swing-motion double trucks, particularly adapt-ed for electrical street-railways, and especially designed to radiate on short curves and to be used under long open cars.
The invention consists in the novel construction of the truck-frame and also in the means for suspending the bolster-springs and spring-plank on swinging supports for the truck-frame, so as to permit swing motion or lateral movement of the bolster relative to the truck.
The invention further consists in the novel details of construction of the truck-frame illustrated in the accompanying drawings and hereinafter clearly described and claimed with reference thereto.
in said drawings, Figure l is a side elevation of the complete truck-frame. Fig. 2 is a transverse section thereof; Fig. 3, a plan view thereof; Fig. 4, a detail longitudinal section on line 44, Fig. 3. Fig. 5 is a detail showing the swinging bail-hanger, spring-plank, and truss-rod in correct position5-Fig. 6, a transverse section through Fig. 5 with one elliptic spring shown instead of two; Fig. 7, a detail showing the ellipticspring arranged directly over the center of the swing-hanger.
Fig. S shows the elliptic spring arranged lon-r gitudinally of the truck. Fig. 9 shows the elliptic spring set down between the mem;
bers of the spring-plank. Fig. l0 shows a modification of the swing-hanger. Fig. Vll
shows a modification of the spring-plank.l
Fig. l2 is a detail vertical section through the pedestal on line 12 12, Fig. l. Fig. 13 is a part plan and part longitudinal section through one-of the pedestals.
The truck is constructed of four malleable or steel pedestals A, the adjoining pedestals at the same side of the truck being connected at top by two parallel bars B, set edgewise and secured to suitable recesses or seats cin projections A3 at the tops of the inner jaws of the pedestals, as shown, and the adjoining pedestals are also connected below 'the bars B vby a single' transverse bar C, whose ends are fitted in sockets a in the lower ends of the inner-jaws. The bars C are arranged vertically edgewise at their ends,but are given aquarter-turn intermediate their ends, so that the central portions c thereof shall lie atwise, as shown, thus giving more room for the accommodation of the swinging hangers I, carrying the spring-seat, springs, and bolster, as hereinafter described, thus permitlting longer hangers to be used. The opposite over the j ournal-boxes E of the axles as usual,
springs e being interposed between the journal-boxes and enlargements or caps a2 on the upper ends of the pedestals to cushion the truck-frame upon the axles. The lower ends of the jaws of the pedestals are connected by short bars A2, the ends of which are fitted into rabbets or recesses a4 in the jaws and secured thereto by bolts or rivets a5, as shown, to preventispreading of the jaws. Secured between the bars B B and located centrally between the adjoining pedestals at each side vof the truck are hanger-castings F, which are preferably lipped over the upper edges of the bars B to relieve theirsecuring-bolts ofstrain, and to the inner face of the inner bars B and centrally-between the adjoining pedestals A are fastened bolster-guide castings G, which are preferably lipped over and under the bars and providedwith inwardly-projecting end lugs g, to which are secured the ends of transverse stay-bars H, by which the truckframe is centrally stayed and lateral spreading thereof prevented. The truck as thus constructed has few parts, but is very stiff and strong.
IOO
The hanger-castings F are provided with two vertical conical openingsf, through which pass the ends of U-shaped hangers I, which are suspended from said castings by means oi' nuts vl on their upper ends, said nuts being preferably convexed on their under sides and adapted to fit in enlarged concaved recesses f at the upper ends of openings f, thus permitting the hangers I to swing freely laterally of the truck-frame.
Supported upon the hangers I is a springsupport O, or what is commonly termed a spring-plank, consisting, as shown, of two metallic bars set vertically edgewise and having their ends notched on their under sides, as at o, to fit on the lower portion of the hangers I, these bars being securely connected together and held a proper distance apart by means of interposed castings P, which project below the bars sufficiently to form stepsp for a truss-rod Q, which lies intermediate and below the bars O; butits ends are carried up over the lower portions of the hangers and through cap-plates q, fitted over the ends of the bars O, as shown in Figs. 5 and 6, and secured in place by nuts q'. Thus a very strong spring plank or support is formed. The castings P also extend above and are lipped over the upper edges of bars O to form spring-seatsp', upon which are supported pairs ot' elliptical springs R R, which are arranged transversely of the truck-frame, but parallel with the spring-plank. Each pair of springs is set a little inward from the ends of the spring-plank, as shown, so that their outer ends will not project inconveniently beyond the sides of the truck. On these springs R is supported the bolster S, which may be of any suitable construction, but is preferably made of a stout truss-shaped wooden beam S, strengthened by two metal side bars s, set' vertically edgewise and properly secured to the wood beam. The bolster lies between the bars I-I H and the castings G and is guided thereby. It is, however, shorter than bars I-I, so that it can have a certain amount of longitudinal movement transversely of the truck-frame, the bolster having the same extent of movement transversely of the truck-frame thatthe springplank O has and in addition has an independent movement on the spring-plank due to the springs R. By reason of this capability of swing motion of the bolster the truck can easily round curves without disagreeable tilting of the car-body and without binding of the wheel-flanges on the rails or in the railgrooves.
The bolster S is provided with a plate and socket or other suitable connection T for attaching the car-body thereto, as is usual, and is also provided with the side bearing-plates N, attached to bars s near each end to prevent undue lateral oscillation of the car-body on the bolster. It will be observed that by reason of the twist in the lower bars C of the side frames of the truck I am enabled to use longer hangers above these bars and can thus get in larger springs and can keep the bolster nearer to the rails than would be possible with the same size of spring if bars C were straight. By this construction a very short wheel-base is obtained, and the motors are to be hung on the outside of the axle with the ends dropped down. This truck can swing around very short radii curves without interfering with the side steps on open-car bodies, and the car-bodies can also be carried very low down and only one step need be used.
Figs. 5 and 6 show the construction and arrangement of the springs and hangers as I propose to build them, only one elliptic spring being shown in these gures, which Will be sufficient in trucks for somes makes of carbodies and will enable me to make shorter wheelbase trucks.
In Fig. 7 the elliptic spring is shown as arranged directly over the center of the swinghanger. This hanger maybe made of a single U-shaped bar, as shown in Figs. l to 6, or, as shown in Figs. 7, 10, and l1, it may be made of two side pieces V, having eyes c on their bottom connected by a rod V', as shown.-
These side rods V may 'ne suspended from the castings F by nuts t', as indicated in Fig. 7, or they may have eyes QJ on their upper end, Ithrough which are passed pins U2 to hang them from the castings. This pin can be made long enough to extend across to take in both ot' the eyes on the upper end oi' the swinghanger, if desired. Fig. 7 also shows another form of bolster that may be used. Such form of bolster is not claimed herein.
Fig. 8 shows how the elliptic springs may be arranged longitudinally or" the truck, the center of the spring being in the same position as in Fig. 5, but the spring being turned around so as to lie parallel with the side frame of the truck.
In Fig. 9 the bars 0 of the spring-plank are set farther apart and the castings P are replaced by drop-castings P2, which allow the spring-seats to come below the top ot' the bars O, thus enabling me to use higher springs without raising the bolster in relation to the truck-frame.
Fig. 1l shows a moditlcation of the springplank, which in this case is formed of a single dat bar O2, laid Iiatwise and trussed by the rod Q, the springs being arranged thereon as in Figs. 5 and 6. In any case the springs can be arranged as in Fig. 7, if desired-that is, with the center of spring directly over the swing-hanger, in which case the truss-rod might be dispensed with.
Any suitable braking mechanism may be used with these trucks, the brakes being hung on the inside of the truck-frame and between the wheels, as partiallyindicated in the drawings, so as not to interfere with the motors or any ot' the movable parts of the truck.
l/Vhile I prefer to use full elliptic springs to support the bolster on the spring-plank, it is obvious that other forms ol' springs might IOO be employed, and therefore I do not limit myself to the use of full elliptic springs, nor do I limit myself to the employment of the twisted bottom bar C, except where specifically mentioned in the claims, in which I have summarized the essential features of my present invention.
I do not herein claim, broadly, the employment of U-shaped hangers between the pedestals carrying the springs and bolster, as these form the subject-mattei' of a compatiion application filed herewith, (Case No. 387,) the present application being designed to cover more particularly the construction of the truck-frame and the arrangement of hangers, spring-plank, springs, and bolster.
