CAR-TRUCK.

T0 all whom/ t nur/ zj concern: 0
Be itlrnown that I, CLARENCE H. HOWARD, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a'new and useful Improvement in Car-Trucks, of which the following is a specification.
My invention relates particularly to the transoms of a car-truck, and has for its object to simplify the construction and increase the strength and stability of the car-truck frame.
The invention consists in substituting for the two ordinary separately-constructed tran- .tion through the transom on line 3 3 in Fig.
1, the truck-bolster and spring-plank with the swing-hangers being indicated by brolren'lines lin Figs. 2 and 3. v
Like letters and numerals of reference denote like parts in all the figures.
co represents a preferably four-wheel car-I truck (omitting irrelevant details) having the wheel-pieces 1, end pieces 2, and truck-bolster 3, with the swing-'hangers 12 and spring-plank 5, all of which parts may be of the ordinary or other suitable construction.
Inl lieu of the two separately-constructed transoms ordinarily used between which the truck-bolster rides I substitute a suitably- 'shaped but preferably rectangular frame b,
- which surrounds the bolster 3 and is composed,
preferably, of cast-steel integral throughout. The frame com-prisesthe two side pieces 6, which correspond to the two ordinary'transoms, and the end pieces 7,.which unite the side pieces 6-together at their end s. The side pieces 6 and end pieces 7 are preferably of an inverted-L shape in cross-section, having their top horizontal flanges 6 and 7', respectively,
directed outward from the vertical legs (or walls of the opening 8 through the frame and united to each other, the usual clearance being allowed between the inner faces of the sides 6 and ends 7 for the play of the bolster 3, as in the case of the ordinary transoms./
The sides 6 are formed at the bottom with depending lugs 9, which are integral with the sides 6 and perforated, preferably, for bushings 10, through which pass the coupling-pins 11 of the swing-hangers 12, (shown by broken lines in Figs. 2 and 3,) 0r the bushings 10 may be dispensed with and the pins 11 passed directly through the lugs 9. Each end piece 7 of the frame is preferably formed beyond each side piece 6 with an extended portion 13, the outer face of the end piece 7 with its eX- tended portion 13, being adapted to butt or bear against the inner face of the corresponding wheel-piece 1 and the top flanges 7 of the ends 7 13 overlapping the wheel-pieces 1. The
frame b thus constructed is firmly secured to the wheel-pieces 1 by bolts 14, which pass transversely through the ends 7 13 and wheelpieces 1, and by bolts 15, which pass vertically through the top flanges 7 and wheel-pieces 1, as shown, the top anges 7 at their junction with the top flanges 6 of the side pieces 6 being curved toward the latter and forming gusset-stays -thereat I do not limit myself to the particular shape in cross-section nor configuration in top view of the frame as above described, as these may be varied as found most desirable in practice. Moreover, if desired, the extensions 13 of the ends 7 may be dispensed with without vdeparture from theprinciple of the invention,
IOOA
ing the said bolster, the sides of the said frame forming a double transom, and the ends of the frame being adapted to butt against the inner aces of the Wheel-pieces, the said ends having respectively a top flange integral with the body and overlapping the corresponding Wheel-piece, and means for securing the said frame to the Wheel-pieces, substantially as described.
2. In a car-truck, the combination with the Wheel-pieces and the truck-bolster, of a suitable frame integral throughout, and surrounding the said bolster, the sides of the said frame forming a double transom and having depending lugs integral therewith for the swing-hangers, the ends ofthe Jframe being adapted to butt against the inner faces of the Wheel-pieces, and means for securing the said frame to the Wheelpieces, substantially as described.
3. In a car-truck, the combination with the wheel-pieces and the truck-bolster, of a suitable frame integral throughout and surrounding the said bolster, the sides of the said frame forming a double transom and each end of the frame having an extended portion beyond each of the said sides, the said end with its extended portions being adapted to butt against the inner face of the corresponding wheel-piece andhaving a top flange overlapping the said piece, and means for securing the said frame with its extended portions to the wheel-Incom, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
