JAMES W. GIBNEY, OF BUFFALO, NEW YORK, ASSIGNOR TO W. P. TAYLOR COMPANY, OF

BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.

GAR-PEDESTAL.

To all whom it may concern:

Be it known that 1, JAMES W GIBNEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improved Oar-Pedestal, of which the following is a specification.

This invention relates to an improved car pedestal and journal box and the object of the invention is to form the complementary supporting surfaces of the pedestal and journal box so that they will be of considerable extent and without abrupt corners and thereby equally distribute the wear strain and prevent excessive wear at any point.

The invention also relates to certain details of construction all of which will be iereinafter escribed and claimed reference being had to the accompanying drawings in which,

Figure 1 is a front view of the improved pedestal with a car journal box in position thereon. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged transverse section through the improved pedestal and the car journal box on line a a, Fig. 1.

In referring to the drawings in detail like numerals designate like parts.

The pedestal consists of the horizontal top cross member 1 and two depending vertical members 2 and 3. A rib or enlargement 4, extends from each of the inner corners of the members 2 and 3 and is provided with an inner surface 5 which is curved and formed without abrupt corners in cross section. A car journal box 6 is adapted to be mounted or supported between the vertical members 2 and 3 of the pedestal and is provided on its sides with vertical grooves 7 which are Specification of Letters Patent.

Application filed January 20, 1908.

Serial No. 11,770.

complementary curved in crosssection to correspond with the curve of the ribs or enlargements 4. Four of the ribs a are preferably employed two on each member and a similar number of grooves 7, are formed in the journal box, two on each side. The in ner surface 5 of the ribs and the surface of the grooves may be chilled in casting to iarden the same. The ribs are made slightly smaller in cross section than the grooves to permit a little play to the journal box when the car is traveling.

The great advantage of this construction is that all sharp and abrupt corners are dispensed with and the wear is distributed equally over a curved surface. Further all wearing st ain is at a different angle at each different point so that the tendency is to wear at all points instead of at one point.

I claim as my invention 1. The combination with a car pedestal having a jaw provided at its corner with a curved surface, of a journal box mounted in said pedestal and having a groove of similar curve in cross section. b

2. The combination with a car pedestal, composed of a top cross member and two depending members having ribs at each inner corner, the inner surface of which is of curving cross section, of a journal box mounted between the depending members and having grooves in which the ribs extend; said grooves being of complementary curving cross section.
