Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed Jul;T 6, 1905. Serial No. 268,377.

To all whom it may concern:

Be it known that I, WILSON E. SYMoNs, a citizen of the United States, residing at Pittsburg, in the county of Crawford and State of Kansas, have invented a new and useful Locomotive-Truck, of which the following is a specification. j This invention relates more particularly to improvements in four-wheeled leading-trucks of locomotives, though there are certain features of novelty not necessarily limited theretoi; as will be apparent to those skilled in the ar )ne of the principal objects is to provide a main frame cast in one piece, thereby greatly reducing the number of parts to be fitted, and consequently reducing the cost of manufacture and maintenance, while increasing the strength and durability of the truck.

Another object is to provide a structure of the above character that will permit the application of the wheels and axles without the necessity of jacking up the truck from the rails a distance equal to the length of the jaws or pedestals.

A still further object is to improve the various details of construction in order to secure simplicity.

One embodiment of the invention is illustrated in the accompanying drawings and is described' in the following specification. An inspection of the claims hereto appended will show thatthe invention is not limited solely to this embodiment.

' In the drawings, Figure 1 is a plan view of the truck. Fig. 2 is a side elevation of the same, the wheels on the nearer side being removed. Fig. 3 is an end elevation of the truck. Fig. 4 is a longitudinal sectional view the main frame, together with the separate pedestals and boxing-shoes detached. Fig. i 6 isa cross-sectional view through the main frame and equalizer-bars. Fig. 7 is a secj tional view onthe line 7 7" of Fig. 6. Fig. 8 is a detail sectional view on the line 8 8 of Fig. 5. Fig. 9 is a top plan view of one of the l binders for connecting the associated pedestals. Fig. 10 is a side elevation of the same.

In the embodiment illustrated a main frame is employed that is of a single piece and of cast-steel. This main frame consists i of side beams 11, end bars 12, connecting the ends of said side beams and integral therewith, and an intermediate transom 13, connecting the central portions of the side beams and formed integral with the same. Each side beam, as particularly lshown in Fig. 8, consists of an upright web 14, provided with inset upper and lower flanges 15 and 16, formedupon the upper and lower margins of the web. The flanges 15 and 16 terminate at the ends .of the side beams and the end bars 12 are inverted substantially L-shaped in cross-section, consisting of angularly-disposed flanges 17 and 18, the former of which constitute upright webs, and the flanges 18 projecting outwardly.

The transom 13 consists of a central bearing or femalecasting having a tubular bowlshaped body 19 with a circular top or bearing-plate 20, carrying an upstanding peripheral flange 21, and having a central bolt-receiving opening 22. On opposite sides of this bearing extend webs 23, integrally joined to the bowl-shaped' body and to the upright webs 14 of the side beams, as illustrated in Fig. 6. Lower flanges 24, extending on opposite sides of the webs 23 and located longitudinally along their lower margins, are integrally connected to the lower anges 16 of the side beams, while upper oppositely-projecting flanges 25, located along the upper edges of the webs 23, extend from the annular flange 21 to the upper flanges 15 of the side beams, these flanges 25 tapering in opposite directions, as shown in Fig. 1.

Depending from the end portions of the side beams are integral pedestals consisting of bearing-plates 26 and brace-webs 27. The outer sides of the plates 26 are provided contiguous to their upper ends with recesses 28. Cooperating with these integral pedestals are other pedestals 29, consisting of bearingplates 3() and bracing-webs 31, said pedestals also having tops 32, that bear against the under sides of the side beams 11 outside the integral pedestals and being secured thereto by bolts 33, which pass through said tops 32 and through the lower. flanges 16 of the side beams. The inner sides of the pedestals 29 are provided with seats 34 similar to the seats 28 of the integral pedestals. These seats are adapted to receive similar-shaped lugs 35, formed upon the upper ends of shoes 36, that detachably fit against the inner faces of the pedestals and are held in place by binders 37, bolted, as shown at 38, to the IOO IOS

IIO

boxes 40. Each of the equalizing-bars consists of an upright web 46, having offset upper and lower marginal flanges 47. A air of the equalizing-bars are associated wit side beam 1 1 of the main frame, being located on opposite sides of the same, as illustrated in Fig. 1, the bars tapering toward their ends, as

, shown. Hanger-stirrups 48 are pivoted by work when the ot means of bolts or pins 49 to and between the equahzer-bars of each set, and supported by .the hanger-stirrups are springs 50, which springs bear against the under sides of the side beams 11 at the juncture of the transom 13 therewith.'

The truck above described is very strong and durable and yet is com osed of very few parts, the main frame, inc uding certain of the edestals, being of one piece which can be rea ily cast and rerluires but little machineer parts are assembled therewith. At the same time by having the outer pedestals detachable the 4axles and wheels can be readily applied without the necessity of jacking the entire truck-body from the rail a distance equal to the height of the pedestals. The various parts are, furthermore, simple in structure, yet very strong to withstand the necessary jars and strains. At the samen time these parts are light in weight and can be readily manufactured.

` From the foregoing it is thought that the construction, operation, and man advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
