MEANS FOR RADIATING CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 480,830, dated August 16, 1892.

Application led April 28. 1892. Serial No. 430,999. (No model.)

To all whom it may concern.-

Be it known that I, HORACE REsLEY, a citizen of the United States, and a resident of Cumberland, in the county of Allegany and State of Maryland, have invented certain new and useful Improvements in Railroad-Car Mounting; and I do hereby declare the followlng 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.

My present invention relates to railroadcar mounting,and is designed,priinarily, as an improvement on my patent, No4-11,976, dated December 2, 1890.

The rocking motion of railroad-cars, especially in rounding curves, throws the greater weight toward the inner rail, thereby lessening the weight on the outer rail and tending to make the truck jump the track. My invention aims to avoid this danger by automatically adjusting the trucks to the rails so that their axles will be in the radial lines ot the curve, which causes the train to move easily along the track without throwing the weight of the train disproportionately on either rail and preventing the wheels of the train from impinging against the outer rail.

With these ends in view the invention contemplates a swinging post pivoted or hinged to a plate secured on the car-body above the ends of each upper bolster, which post operates in a countersunk portion of a bearingplate secured on the upper bolster, said bearing-plate being bent upward to provide a rest for the car-body on turning a curve.

My invention further consists of the construction and arrangement of parts, as will be hereinafter fully described and claimed.

To enable others to readily understand the invention, I have illustrated the same in the accompanying drawings, in which- Figure l is a side elevation. Fig. 2 is a transverse sectional view on the line a of Fig. l. Fig. 3 is a detail view showing the position of the swinging post on the inner end of the bolster when rounding a curve. FigAf is a detail view showing the position of the swinging post on the outer end of the bolster when rounding a curve.

Refer-rin g to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates the bottom of the car-body, and B B the trucks, which are pivotally connected to the car-body by kingbolts a. The lower bolster b is connected with the cross-piece Z9 on the truck by pins or bolts C, and suitable coiled or elliptical springs c are interposed between the lower bolster and the cross-piece on the bolts C or other bolts to provide a yielding bed for the car. At the outer end of each lower bolster, on the upper side thereof, is a bearing-plate D, which is partially or Wholly countersunk, as desired, and is constructed and bent to form a depressed seat CZ and a shoulder d in front of said seat. y This plate is rigidly secured to the bolster in a suitable manner, and by countersinking the same it is more eitectually held fromV displacement. preferably made of one piece of metal; but this is not essential, and it may be constructed ot two or more pieces and solid at cl', if desired. Above these plates, on the outer end of each upper bolster E, is a plate e, which is countersunk, preferably, and provided with an upwardly-extending offset or shoulder e, which affords a firm hold upon the bolster and prevents a backward strain, and displacement of the plate. A swinging post or spar F is pivoted or hinged to the plate e at one end, and it extends downward and rests in the seat d of each bearing-plate on the lower bolster. It will be observed that these swinging posts are pivoted on opposite ends of the plates e on the same side of lthecar and on the same ends of said plates on the opposite ends of the holsters for a purpose hereinafter described. 'lhese plates e and swinging posts F are preferably made of strong metal, as they are designed to partially sustain the weight of the car and are subjected to the various uneven and unusual movements of the car, which they are designed to obviate.

The operation of my improvements may be stated as follows: Vhen the car is traveling along a straight track, the swinging posts will be inclined at a slight angle to the body of the car and fitted in the seats d of the bearing-plates, the swinging posts on the same The bearing-plate is IOO side of the car being inclined reversely toward each other and the shoulders d being on opposite sides of said posts. When the car is rounding a curve, the outer rail being always higher than the inner rail the outer edge of the car-body and outer sides of the trucks approach each other, which is also largely due to centrifugal action; but the swinging posts on the inner sideof thecar-body will assume a vertical position and maintain the carin its properlevel. As the car reaches and begins the curve, the increased pressure on the outer side of the car forces the swinging posts in the direction in which they are inclined reverselyto each other, andthis forces the outer ends of the front truck forward and the corresponding end of the rear truck backward. This position of the trucks will thus bring the axles thereof into diagonal positions with reference to each other and the axes of the Wheels into the radial lines of the curve, which adapts the truck to move easily and smoothly around the curve without unduly impinging against the rails. At the same time the inner ends of the trucks will move toward each other, and the swinging posts will thus be forced into a vertical position and elevate the inner side of the carbody, keeping the car-body in a level position.

To relieve the swinging posts of as much strain and weight as possible, the shoulders d are provided,and the outer side of the car may rest partially upon said shoulders as the curve is being rounded. When the curve is rounded, the devices will automatically return to their original positions.

My improvements may be adapted to all kinds of railway-cars, locomotive-trucks, and to other cars or vehicles.

I am aware that changes in the form and proportion of parts and details of construction of my invention may be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the trucks of a car and the body mounted thereon, of the swinging posts hinged to the car-body and arranged to bear against the truck-bolster and adjust the trucks to a curve of the track, substantially as described.

2. The combination, with the trucks of a car and the body mounted thereon, of the bearing-plates on the lower bolster and the swinging posts hinged at one end to the carbody and adapted to bear at their free ends against said plates, substantially as and for the purpose described.

3. The combination, with the trucks of a car and the body mounted thereon, of the bearing-plates secured on the lower bolsters and having depressed seats and the posts depending from the body and fitted 1n said seats and adapted when rounding a curve to adjust the trucks so that the axles thereof will be in the radial lines of the curve, substantially as described.

4. The combination, with theutrucks of a car and the body mounted thereon, of the swinging posts pivotally secured to the carbody or upper bolsters and the bearngplates on the lower bolsters, having seats to recelve the free ends of said posts, substantially as and for the purpose described.

5. The combination, with `the trucks of a car and the body mounted thereon, of the swinging posts pivotally hung from the upper bolsters and the bearing-plates secured on the lower bolsters beneath said posts and having seats to receive the free ends of the posts and also provided with the shoulders to sustain the car-body, substantially as described.

G. rlhe combination, with the trucks of a car and the body mounted thereon, of the lower bolsters on the trucks and the upper bolsters on the body of the car, the bearingplates secured on the lower bolsters, and the shoulders on said plates to receive the weight of the car, substantially as described.

7. The combination, with the trucks of a car and its body mounted thereon, ot' the bearing-plates secured on the lower bolsters and having depressed seats therein, the plates secured to the upper bolsters, and the swinging posts pivoted or hinged to said plates and having their free ends fitted in said seats in the bearing-plates, substantially as described.

In testimony whereof Iax my signature in presence of two Witnesses.
