Patented Sept. 25, 191.7.

Application filed August 17, 1916. Serial No. 115,506.

2 '0 all whom it may concern:

Be it known that I, Bvnns W. KADEL, a citizen of the United States, residing in the county of Roanoke and State of Virginia,

5 have invented certain new and useful Im provements in Oar-Trucks, of which the following is a specification.

This invention pertains to car trucks and among the objects thereof is to provide a truck having :rigid oil oxes; that is, oil boxes that do not have a sliding motion in pedestals or guides. It is wellknown in the art that boxes of the pedestal type are considerably more costly 15 of construction and are likewise more costly to'kcep in repair.

Another object is to provide a system of equalizing members that, while being perfectly flexible, will yet, offer some resistance out of their normal positions and will induce forces that will tend to return the parts at all times to their normal positions. Other objects will appear as the description is set forth.

The invention consists of the formation,

combination and arrangement of parts as will be herein described and claimed.

I In the drawings, Figure 1 is a side elevag'tional view of a. truck embodying the fea- Sutures of my invention, and Fig. 2 a broken plan view of the same.

a In these drawings the truck is shown as sup lied with three axles-1, 2 and 3-these having the usual wheels 4 mounted thereon.

A side bar 5 extends along either side of the truck find there are secured to the opposite ends of it the oil boxes 6 and 7 for the end axles 1 and 3. This bar 5 is supported upon these end oil boxes and at either side of the middle axle 2 links 8 and 9 streettached to it at 10 and 11 respectively. The

,middle oil boxes such as 12 are each provided with longitudinally disposed arms 13 and 14 cast out from opposite sides of the same. Thus this oil box constitutes a rigid, centrally disposed lever of cast metal supported upon the middle axle and rotatable about its center as an axis. End equalizers 15 and 16 0 extend from the ends of these arms to the links 8 and 9, being connected to the latter at 17 and 18 respectively. ner ends of these end equalizers are supported by the central lever and the outer 6 ends of the same by the end oil boxes,

through the bar 5.

Thus the in-- The load of the car body is received on a center bearing plate 19 which is carried by a load supporting truck bolster 20. The bolster has arms such as 21 and 22 that extend outward and are supported upon the end equalizers 15 and 16 between the points of support of these levers. Springs 23 are interposed between the bolster arms and the equalizers for cushioning purposes. Guides 24 may be supplied on the side bar 5 to aline .the bolster and a guide 25 may be provided to aline the oil box 12 with respect to the side bar, this guide occupying a coalining opening in the under face of the bar 5. Guides 26 may also be supplied to aline the ends of the levers 15 and 16 upon the arms 13 and 14.

One of the special features of the invention is the method of supporting the ends of the levers 15 and 16 upon the arms 13 and 14. These supports are each made at two points 27 and 28, spaced longitudinally of the levers with respect to each other. By so supportin these parts there will be required some orce to swing the several levers out of their normal positions or to swivel the central lever about the middle axle. For such swiveling will change the relative lengths of the levers and tend at. all times to return the levers to their normal positions.

I am aware that trucks having a similar the guide 25 is employed, while there will I be some slight relative movement, between the side bearing 5 and the guiding flange 25 on the middle oil box, when equalities are encountered in the road bed, yet there is not' present the constapt and excessive vertical movement that when springs are interposed in the supports between two such engaged parts, as for example betwecn oil box. and pedestals in many trucks of the pedestal type.

exists in pedestal trucks as Having thus described my invention,

what I claim is:

1. In a six-wheel car truck, three axles with the customary wheels and oil boxes mounted thereon, the oil box for the middie axle having oppositely extending arms and comprising a centrally disposed longitudinal lever rotatable about the middle axle as a center, a pair of end lever members extending in opposite directions from opposite ends of the said central lever and supported at their inner ends thereby, the outer ends of said end levers being supported by the oil boxes of the end axles, the support of the end lever members upon the central lever being so formed as to offer resistance to any swiveling of the central lever about the center axle out of its normal position and to always return the lever to its normal position.

2. In a six-wheel car truck, three axles with the customary wheels and oil boxes mounted thereon, the oil box for the middle axle having oppositely extending arms and comprising a centrally disposed longitudinal lever rotatable about the middle axle as a center, a pair of end lever members extend ing in opposite direction from opposite ends of the said central lever and supported at their inner ends thereby, the outer ends of said end levers being supported by the oil boxes of the end axles, the end lever members being supported by the central lever in such'manner as to change the relative lengths of the levers when the central lever swivels around the middle axle out of its normal position.

In a six-wheel car truck, three axles with the customary wheels and oil boxes mounted thereon, the oil box for the middle axle having oppositely extending arms and comprising a centrally disposed longitudinal lever rotatable about the middle axle as a center, a pair of end lever members extending in opposite direction from opposite ends of the said central lever and supported at their inner ends thereby, the outer ends of said end levers being supported bycthe oil boxes of the end axles, an end lever member I being supported upon the central lever at two points spaced one from the other longitudinally of the truck.

4 In a six-wheel car truck, three axles with the customary wheels and oil boxes mounted thereon, a longitudinally extending side bar to the opposite ends of which are rigidly secured oil boxes for the two outer truck axles, the said side bar bein supported upon the said end oil boxes, t e oil box for the middle axle carrying longitudinally extending arms at either of its sides and forming a central lever rotatable about the middle axle as a center, end levers extending longitudinally from said central lever toward each end of the truck and being supported upon the said central lever at their inner ends, the outer ends of the end levers being supported upon the said side bar, and

means for applying the load of the car body to the said end levers between the extremities thereof.

5. In a six-Wheelcar truck, three axles with the customary wheels and oil boxes mounted thereon, a longitudinally extending side bar to the opposite ends of which are rigidly secured oil boxes for the two outer truck axles, the said side bar being supported upon the said end oil boxes, a centrally disposed, longitudinally extending lever to which is rigidly secured the middle oil box, said lever being rotatable about the middle axle as a center but only in harmony with the axial movement of the attached oil box, end levers extending longitudinally from said central lever toward each end of the truck and being supported upon the said central lever at their inner ends. the outer ends of the end levers being supported upon the said side bar, and means for applying the load of the car body to the said end levers between the extremities thereof.

6. In a six-Wheel car truck, 3 axles with the customary wheels and oil boxes mounted thereon, a longitudinally extending side bar to the respective ends of which are rigidl secured oil boxes for the two outer trucl i axles, the said side bar being supported upon the said end oil boxes, the oil box for the middle axle comprising a centrally disposed and longitudinally extending cast metal lever rotatable about the middle axle as a center, end levers extending longitudinally from said central lever toward each end of the truck and being supported upon the said central lever at their inner ends, the outer ends of the end levers being supported upon the said side bar, and means for applying the load of the car body to the said end levers between the extremities thereof.

7. In a six-wheel car truck, three axles with the customary wheels and oil boxes mounted thereon, load-receiving and supporting means and load-equalizing means, the said load-equalizing means embodying a central lever integral with the middle oil box and rotatable about the middle axle as a center, said equalizing means embodyin v also additional load-equalizing members a apted to cooperate with the said central oil-box lever, the said equalizing means being so formed as to give perfect equalization only when the said central oil box lever is in normal position and to give unequal distribution of the loads when the same is rotated out of its normal position. i

In testimony whereof I ailix my signature in presence of two witnesses.
