In the drawings, A is a pedestal of a car- The drawings illustrate the new elements which are embodied and are integral with this tension-spring support, and they show it to be provided with a centrally-located springholding cup 2', having its bottom 11 below the plane of the lower sides of the lugs I I and forming a seat for the lower end of the said spring, while the side walls 6 serve as a reinforcing element for sustaining the spring in a vertical position and from deflection when in active service. It is also shown to be provided with a central perforation 2' calculated to receive the lower end portion of a central guide-bolt J, which may pass through the bore of the body of the tension-spring for stiffening the same when this invention is to be employed in trucks of cars intended to be run at high speed or on roads having heavy grades or sharp curves. This spring-support is also shown to be provided with abutments 2', calculated to have bearing against the side walls a a of the jaws of the pedestal and the tiepieces K K, secured to the lower ends of the members or horns of the pedestal for preventing said spring-support shifting in any direction. l

J is a central guide-bolt provided with a broad head j, which latter is seated in the recessed seat ll, formed with the housing B, while its body passes through the bore of the tension-spring G and its lower end portion through the central perforation i of the spring-supgort I. In some cases this guidebolt may be omitted, if preferred, yet in most cases I prefer to employ it for supplementing the reinforcing element of the side walls 1' of the spring-receiving cup of said springsupport.

K K are tie-pieces secured by their ends by means of bolts It to the lower ends of the horns of the pedestal for securely holding the said horns of the pedestal from spreading when the truck of which it forms a part is loaded. This tension-spring G and its supporting-piece I may be modified in their form, as may be found to be advantageous for embodying this spring in trucks of cars for elastically supporting the housing within the pedestals of the truck, without departing from the spirit of this invention.

hen the truck (not shown) embodying tension-springs G, as above described, is in active service, these springs react against the load-bearing springs E and impose on each such a degree of tension as to cause them to carry the load, whether light or heavy, without jolt-ing or sudden shocks or vibrations, as heretofore attending trucks of old 0011- struction, while at the same time the endwise thrusts of the car-axles of the truck will be opposed by the elastic elements derived from the use of these tension-springs, as above described.

Having described my invention, what I claim is The combination with ahousing, of an aXlejournal, contained within a pedestal of a cartruck, and a load-supporting spring interposed between the pedestal and said housing and having its end portions seated in recessed seats provided respectively with the pedestal and housing, of a recessed seat integral with the lower side of said housing, a spring-support secured to the lower ends of the horns of the pedestal, and provided with a springreceiving cup-form seat, and a central perforation in the bottom of said seat, of a tensionspring held under tension and contracted be tween said housing and spring-support, and the central guide-bolt having its head end within the lower side seat of the housing, and its body portion working in the central bore of the tension-sprin g with its lower end working through the central .perforation in the seat of the springsupport, substantially as and for the purposes set forth.
