STEEL RAILWAY-FREIGHT-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 578,579, dated March 9, 1897. Application filed January 6, 1897. Serial No. 618,185. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK S. OWEN, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have. invented certain new and useful Improvements in Steel Railway- FreightOar Trucks; and I do declare the following-to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon which form a part of this specification.

My invention relates to improvements in trucks for railway-cars, principally for use under freight-cars, and has advantages over those heretofore in use, and especially over the form in general use known as the archbar truck, composed partly of metal and partly of wood, put together with rough bolts passing through unfinished holes and subject to racking, twisting, and getting out of alinement, thereby causing vexatious delays and expense and great uncertainty of cars reaching their destination on time or without being wrecked when mounted on such trucks. Besides, the old-style trucks are needlessly heavy and therefore entail the necessity of hauling non-paying dead-weight.

To overcome the disadvantages enumerated, I have constructed a truck of light but sufficiently strong shape, and have used therefor many parts of pressed steel, all my parts being solidly and unyieldingly riveted together, except where it is necessary for them to be removed, in which instance the The thrusts of the wheel-flanges against the rails in the old-style truck forced the frames out of square, causing hot boxes, excessive rail and flange wear, and friction to be overcome by the locomotive, thus impairing its earning capacity, while causing its useless wear and tear and the extra expenditure of oil and fuel. In my truck its weight is carried upon springs over the axle-boxes,thus reducing the dead-weight which unyieldingly bears upon the rails and hammers their joints in its passage and jolts and destroys the car-body and its contents. I unite the ends of my truck transversely, thus making one side assist the other in resisting shocks incident to curving and also affording a means to secure the brakes to the outside of the wheels, where they are more readily applied or removed, and more certain to be more carefully inspected than when hung inside, where they are not so readily seen, thus saving time in renewals-either in the shop or in case of failure upon the road in train service, and also by the ease of inspection insuring better and more certain service and less liability to damage of cars, their loads, and the railway from accidents. My truck is so constructed that its users can make their own repairs, thus saving loss of service from having to transport the truck a distance to its makers or to provide at much expense an equipment of special machinery and shops for such repairs.

I am aware that there are others who have experimented to overcome the objections to the arch-bar trucks heretofore so generally used, but in my construction I have embodied features which are new and useful beyond such constructions which have preceded mine, and which are wholly essential to overcome all of the evils heretofore existing, and which have only been partially touched upon by others.

I attain these objects by the mechanism illustrated in the following drawings, in which Figure 1 is a side elevation. Fig. 2 is a plan of one-half of the truck, both sides being alike. Fig. 3 is an end View of one-half of the truck. Fig. 4 is a vertical section on line 00 m, Fig. 2.- Fig. 5 is a vertical section on line y y, Fig. 2. Fig. 6 shows panel-plate before being bent to shape.

Similar characters of reference refer to similar parts throughout the several views.

The sides of my truck are composed of central panels 1, preferably of pressed steel having flanges 2 3 4 5 turned inwardly, the flanges 2 4 being narrower than 3 5, which project at quite a distance inward, as will be further described hereinafter.

4 and secured thereto are pedestals 6 7, formed of U-sect-ion bars either rolled or pressed, the bars being bent to the shape of an inverted n, the connected top of which reaches exactly flush with the topof flange 3 of panel 1, and the ends of the downwardly-extendin g Adjoining the flanges 2 IOO legs 8 9 passing somewhat lower than the flange 5 of panel 1. I

At 10 11 12 rivets attach the pedestal 7 to the flange 4, the rivets 11 12 having countersunk heads to clear the axle-boxes introd need into the pedestals. Rivets l3 secure the pedestal 7 to the panel 1. The pedestal 6 is secured exactly similar by rivets to panel 1. Above and along the top of flange 3 of panel 1 I place a bar 14 of U section, which I secure by rivets 15 to flange 3. The bar 14 also extends over the tops of the pedestals 6 7 within their flanges 16 17, and thereafter is downwardly turned over the outer legs 9 of the pedestals 6 7, conformin g to the shape thereof, snugly fitting and secured by rivets 18 19 20,

, the rivets 19 20 having countersunk heads inside the pedestals for the purpose heretofore mentioned regarding rivets 11 12. l/Vhen about midway down pedestal-legs 9, the bar 14 is bent to reach out horizontally from the pedestal, as seen at 21. Along the bot-tom of the panel 1 and snugly fitting underneath its flange 5 a bar 22 is placed and secured thereto by rivets 23. The ends 24 of the bar 22 are turned downward within the flanges 16 17 of the pedestal-legs 8 and are'secured to the pedestals 6 7 by rivets 25, which have countersunk heads to clear the axle-boxes, as heretofore noted.

Attached to the legs 8 of pedestals 6 7 are diagonal braces 28, secured by countersunkhead rivets 29, lying within the flanges 16 17 and thereafter passing upward and united to bar 22, flange 5, and transoms by rivets 31. Attached to the legs 9 of the pedestals 6 7 are diagonal braces 32, secured by countersunkhead rivets 33, lying within the flanges 16 17 and thereafter passing upward and united to bar 14 and transverse ties 34 by rivets 35. Thus it will be seen that the pedestals of each side of the frame are secured to the panels 1 through bars 14 22, braces 28 32, and by rivets directly through the panel and its end flanges 2 4, making a strong but light strnc ture.

The lower ends of pedestal-legs 8 9 are spaced by the tie 27, seated on and overlapping them, and the legs 8 9 are held against the tie 27 by bolts 36, which pass through the lower ends of braces 28 32, bar 22, and pedestal-legs S 9, and have lock-nuts 37 and key or split pin 38 to ,prevent any jarring off. Transo1ns30 extend across the truck adjacent to its transverse central line, one being each side thereof. These transoms are preferably made of mild steel pressed to shape, being in depth equal to the distance between flanges 3 5 of panel 1, their section being U-shaped, having the flanges extending outward, the

flanges being wider at the center than at the ends of the transoms, where they are curved outward, forming feet 39, which are secured to the inside of panel 1 by rivets 40, to flange 3 by rivets 41, to flange 3 and bar 14 by rivets 42, to flange 5 by rivets placed same as 41, and to flange 5, bar 22, and braces 28 by rivets 31,

1 are carried well in toward the center of the truck, the distance only being limited by a clearance for the wheels, and much farther than can be done in those constructions where the brakes are hung to the outside of the transoms. The length of the flanges 3 5 atthe inner extremity corresponds with the overall measurements of the transoms at the same point, and thereafter the flanges 3 5 lengthen in diagonal lines to a distance equal to the distance between the flanges 16 17 of pedestals 6 7.

At the center of the truck is a center plate 43, preferably of pressed steel, overlapping transoms 30 and lipped over the same at the outer edges 44. Under the center plate is a tie-support 45, of pressed steel,which extends somewhat beyond the center plate transversely, has its top 46 directly under the center plate and flush with the tops of transoms 30, and from the top 46 flanges 47 extend downward against the inside of transoms 30. Orimps 48 are formed in the tie-support 45, longitudinally at its center, to give added support to the center plate 43 and also to add to its own strength. Rivets 49 unite the tiesupport to the transoms 30, while rivets 5O secure the center plate 43 to the transoms 30 and rivets 51 secure it to the tie-support 45. At the center of the truck, at the lower side of the transoms 30, I secure a tie 52 by rivets 53. Thus it will be seen that transoms 30 are securely and immovabl y tied to each other by center plate 43, tie-support 45, and tie 52. King-bolt hole 57 is formed in center plate 43, support 45, and tie 52 Side bearings 54, preferably formed of pressed steel, are secured to flanges 3 of panel 1 by rivets 55. I wish to call particular attention to the fact that my construction is devoid of any gussets, which are so extensively used in other constructions of trucks.

The transverse ties 34 at each end of my truck extend across from one side structure to the other and are straight, except as to their ends, which curve inwardly and rest in pockets 56, formed by flanges 26 of bar 14, where they are secured by rivets 35. The ties 34 not only tie the ends of the frames beyond the pedestals and assist one side to resist the shocks and strains subjected to the other side, but they also provide a' means whereby the necessary brake-shoes and brake-beam suspensions, hangers, and springs may be attached to enable the brakes to be applied to the outside of the wheels,where they are much more accessible for the purposes of renewals and inspection than when applied to the inside of the wheel, and the work of application, repairs, and inspection being thus greatly fa 'cilitated insures greater service to the truck,

its car, and the goods carried thereby-I have made my truck of few pieces and have no small flanged or gusset pieces in its con struction, and while pressed steel has been mentioned in describing such details as center plate and side bearings it is in noman; ner essential that such must be used, as those members will be of such construction as to conform to those now used by railway companies to secure uniformity in adapting my truck to cars already in use.

It will be observed that my centralpanel 1 is of the same construction for each inwardlyprojecting flange 3 5 and has as secure a hold upon the lower flanges of transoms 30 as upon the upper flanges, and can have its flanges 3 5 extend inwardly upon the transoms 30 for a much farther distance than where they must be kept out of the way to clear brakes hung inside of the wheels upon the transoms, thus afiording greater strength at the union of the sides and transoms than heretofore secured in other like structures and greater security against the twisting of the frame sidewise, aside from the added securing given by the transverse ties 34.

Having now described the manner in which I prefer to carry out my invention, but with out limiting it to the exact form of its parts or the exact fastening of those parts to each other, I claim- 1.
