Application filed July 10, 1912. Serial No. 708,605.
To all whom it may concern:
Be it known that I, GEORGE E. ANDREWS, a citizen of the United States, and a resident of Santa Rosa, county of Sonoma, State of California, have invented certain new and useful Improvements in Center-Bearings for Railway-Cars, of which the following a full and clear specification, reference being had to the accompanying drawings,in which is illustrated a vertical sectional view of one form of nay invention with only sufficient adjacent parts of the body and truck bolsters illustrated 'to show the application of the invention. 7
This invention relates to an improved center bearing for railway cars both freight and passenger.
The object of the invention is to provide a center bearing for railroad cars of a SlJII-- ple, efficient, durable and strong construc tion, which is not subject to the disadvantages of the present construction.
My invention consists, in its preferred construction, of an upper circular bearing, formed integrally with or secured to the body-bolster, having a central downwardly tapering conical pivot and a lower circular bearing on the truck-bolster having a central conical seat therein converging downwardly and adapted to receive the conical pivot on the upper plate, for the purposes hereinafter set forth.
Heretofore generallyin the construction of center bearings it has been the practice to secure the upper center plate to the body bolster, the lower center plate to the truck bolster, and to hold the truck to the car' frame by a king bolt passing through the.
springs are used on the truck and the entire shock is sustained by the king bolt.
The purpose of this invention is to provide a center bearing in which the king boltwill be dispensed with. and the oscillating improved construction.
motion of the car-body in any plane will be taken up or resisted without danger of breaking the hearing or causing it to bind.
In the drawing annexed, a designates a port-ion of the body bolster, which may be constructed in any suitable manner and may be a bolster for passenger cars or for freight cars, and b designates a portion of the truck bolster which also may be of any usual or Attached to or formed as an integral part of the body bolster is a downwardly facing circular bearing 0 depending concentrically from which is a downwardly tapering pivot d. On the up per face of the-truck bolster is a circular, upwardly-facing bearing e which forms a companion bearing for the bearing 0. The cone depends into a cup or socket f carried by the truck bolster and preferably formed i'ntegral therewith. The base of the conical cone 0? fits the upper end of the socket but owing to the difference in taper. between the external surface of the cone and the internal surface of the socket or cup, the body of the cone does not under normal conditions contact with the inner face of the socket, there being a downwardly-flaring space 9 between the pivot and the socket. As shown in dotted lines the ,cone may be hollowed out socket allows the body bolster and upper bearing 0 to rock on the truck bolster without subjecting the cone to strain. -As the greater strain on the king bolt (when that construction is used) occurs at the line between the upper and lower center plates or bearings, the base of the cone in the present improvement is situated atthat point, where of the car body.
2 Learned Having thus described my invention, what which said cone depends, there being a I claim as new and desire to secure by Letdownwardly flaring clearance between the ters Patent, iscone and the inner wall of the socket, for
In combination with a truck bolster carrythe purposes set forth. 5 ing a downwardly facing circular center In testimony whereof I hereunto aflix my 15 bearing, said center bearing having a central signature in the presence of two witnesses.
