TO who??? it y OOH/667%: bar,-of the side frames of the truck, said side Be it known that I, BENJAMIN NV. TUCKER, frames being duplicates of each other.

a citir en of the United States, and a resident Intermediate the central portion of the up of Newark, in. the county of Essex and State per and lower bars of each side frame is seof NewJersey, have invented certain new and cured an open frame 13, comprising the ver- 5 5 useful Improvements in Car-Trucks, of which tical members 14 14, the lower horizontal memthe following is aspecification. her 15, extending inwardly from the lower The invention relates to improvements in ends of said vertical members, and the upper car-trucks, and particularly to improvements horizontal members 16 16, extending outo in car-trucks of the diamond pattern; and my wardly from the upper ends of said vertical 6o invention consists in the novel features and members 14 14, said frame 13 being prefercombinations of parts hereinafter described, ablyin one integral piece of metal and definand particularly pointed out in the claims.

(Not shown.) The lower member 15 of particularly at their'central portions, and to the frame 13 is secured by bolts 17, passing so construct and connect said side frames that through said member 15 and also through the the squareness of the truck may be preserved lower arch-bar and tie-bar and being adjacent and yet that the truckwheels may be able to the lower ends of the vertical members 14,

25 to so construct and secure the transoms that T he frame 13 at ts Outer edge is preterthey are rendered capable of withstanding seably flush with the outer vertical edge of the vere strains, and a further object of the inside frame, and in the preferred construction vention is to provide at the central portions of as a whole I the said frame 13 at its inner edge each side frame arectangular frame secured extends inwardly to a substantial distance 30 to the upper and lower bars of the side frame beyond the inner vertical edge of said side 30 and extending inwardly therefrom to receive frame, whereby the said frame13 is made to the springs, whether the latter be groups of constitute a substantial structure of great coiled or elliptic springs, forthe bo:ster,which strength and durability and affording not with the construction presented may be of the only a means for connecting the upper and 3 5 minimumdength. lower bars of the sideframe and of receiving The invention and satisfactory means for the ends of the transoms, but furnishing a carrying the same into effect may be fully unsubstantial reinforcement of said transoms derstood from the detailed description hereinat the inner sides of the side frames and also after presented, reference being had to the aca suitable flooring or support (represented by 4 companying drawings, in which the member 15) to receive the groups of coiled Figure 1 is a side elevation of a diamond springs (not shown) upon which the ends of truck embodying. my invention, the wheels the bolster (not shown) are usually supportand the pedestahframes for the axle-boxes ed. The invention is not confined to the embeing omitted, because they form no part of ployment of coiled springs for the support of 45 the present invention. Fig. 2 is a top view, the ends of the bolster, since, as is well known, partly broken away, of same; and Fig. 3 is a car-truck bolsters may be supported upon a sectional view of same on the dotted line 3 3 elliptic or semi-elliptic springs, and when it of Fig. 1. g V is desired to employ such springs it will be In the drawings, 10 designates the upper found that the present invention presents a 5 arch-bar, 11 the lower archbar, and 12 the tiestructure capable of supporting the hangings oo for such springs, as will be hereinafter mentioned. The frame 13 is therefore a substantial frame, extending intermediate the upper and lower bars of the side frame and being greater in Width than the width of the side frame, so that it (said frame 13) may eX- tend inwardly beyond and from the side frame to reinforce the transoms and afford abundant space for the bolster and its springs, it being possible with the present construction to employ a bolster of the minimum length whether coiled springs or elliptic or semi-elliptic springs are used for supporting the same.

The transoms 21 are of angle-iron formation, and in the preferred construction these transoms are arranged as illustrated in the drawings, the horizontal members 20 of the transoms being between the upper members 16 of the frame 13 and thelower surfaces of the upper arch-bar 10, and the vertical members of said transoms being against the facing vertical sides of the members 14 of said frame 13, to which members 14 the said transoms are preferably being secured by rivets 22. The transoms 21 connect, as usual, the side frames of the truck, and said transoms extend from the outer edge of the frame 13 at one side of the truck to the outer edge of the like frame at the other side of the truck, the end portions of said transoms being in contact with the upper portion of said frames 13, whereby they become reinforced and strengthened by said frames.

The transoms 21 due to their construction and the fact that their upper horizontal members are intermediate the upper arch-bar and the members 16 of the frame 13 are rendered extremely durable and capable of supporting any parts which it may be desired to suspend from themas, for instance, hangers for elliptic springs to receive the ends of the bolster. The transoms when arranged as shown are at their ends supported by the frames 13, and with said frames 13 afford a very durable structure capable of resisting the usual strains which come upon car-truck transoms, and also of supporting any parts which it will be desired to suspend from said transoms.

The box strap-plate 19 may be in one or more pieces, but is preferably in one integral piece, and in the present instance said strap rests upon the upper arch-bar and at its end portions extends over and upon the upper members 20 of the transoms 21, to which said ends of said strap 19 are secured by bolts 23. The strapplate 19 does not cover the space at the inner edge of the side frames and intermediate the transoms, and the end portions of the strap 19 are the important parts thereof, although increased strength is secured when the strap is in one integral piece, as shown.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-truck, the side frames comprising upper and lower bars, and the frame 13 intermediate said bars and comprising the vertical members 14, outwardly-extending upper members 16 and inwardly-extending lower member 15, said frame 13 being interposed between-the upper and lower bars of the side frame and at its inner portions extending inwardly beyond said side frame, combined with the angle-iron transoms con necting said side frames and at their end portions engaging said members 16 and the upper portion of said members 14, and means for securing said transoms and frame 1% to said side frames; substantially as set forth.

2. In a car-truck, the side frames comprising upper and lower bars, and the frame 13 intermediate said bars and comprising the vertical members H, outwardly-extending upper members 16 and inwardlyextending lower member 15, said frame 13 being interposed between the upper and lower bars of the side frame and at its inner portions extending inwardly beyond said side frame, combined with the angle-iron transoms, 21 connecting said side frames and engaging said members 14 and 16, the strap-plate 19, and means for securing said strap-plate, upperbar, frame 13 and transoms together; substantially as set forth.

Signed at New York, in-the county of New York and State of New York, this 24Cth day of August, A. D. 1903.
