FERDINAND E. CANDA, OF NEW" YORK, N. Y.

TRUSSING FOR RAILROAD-CARS.

SPECIFICATION forming part of Letters Patent No. 426,238, dated April 22, 1890.

Application filed February 27, 1890. Serial No. 342,000. (No model.)

To all whom it may concern:

Be it known that I, FERDINAND E. CANDA, of New York city, in the county and State of New York, have invented a new and Improved System of Trussing Railroad-Cars, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which-- Figure 1 is a longitudinal section of an ordinary car-body, and Fig. 2 is a longitudinal section of a car-body embodying myiinproveinent.

Similar letters of reference indicate corresponding parts in both views.

My invention consists in dividing that portion of the length of the car between the body bolsters into four or more panels by the addition of one or more cross-sills and necessary supporting-struts.

The old plan of trussing in general use divides the length or distance between the bodybolsters of acarinto three panels A B C, using two cross-sills D D,with either two or four longitudinal truss-rods F, as shown in Fig. 1. These longitudinal truss-rods F receive the strain direct from the cross-sills D and struts a and carry it to the body-bolsters b, from which it is distributed to the trucks, the ends of the rods being anchored in to the end sills c.

In my system of trussing I use the same plan described above; but I introduce in it one or more additional cross-sills D below the level of the earfioor, as shown in Fig. 2, with another set of two or four truss-rods F, also placed below the car-fioor, anchored either in end sills c or body-bolsters b. This central set of truss-rods takes up the strains in the central panels and distributes or carries them to the cross-sills and struts forming the end panels, and thence to the body-bolsters and. trucks, as before described. In addition to this, I introduce into the construction of the car lateral rods F anchored to body-bolsters. (Shown by the dotted line in Fig. 2.) These rods are to represent an absent load-in other words, to hold the car down when empty, so that should the car be placed in a train of loaded cars when empty and backed into a siding or elsewhere it will not be broken by being raised in the center, as the lateral rods will hold the center down to its camber lines. Cars frequently fail under this service, and this construction is especially applicable to iron cars, (cars constructed with iron sills,) making it possible to build them longer than heretofore and at the same time secure a much better distribution of materials in their construction.

As willbe observed, the auxiliary sills, struts, and truss-rods are placed below the floor-level to allow of supporting the central portions of the car without interfering with the carrying capacity of the car or in any way obstructing the floorspace. This construction is of great importance, especially in flatcars.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a system of trussing railroad-cars, the combination, with the car-body, of auxiliary truss-rods placed below the floor-level for supporting the central portions of the car, substantially as specified.

2. A ear-body provided with two sets of truss-rods placed below the floor-level and oppositely arranged with respect to each other, substantially as specified.
