REMOVABLE PEDESTAL LINER Filed Dec. 10, 1929 ATTORNEYS Patented July 21, 1931 narrate STATES PATENT OFFICE ROBERT G. ANDERSON, OF PLAINFIELD, NEW JERSEY, ASSZGNOR TO INTERNATIONAL MOTOR COMPANY, OF NEW YORK, N.
'1 A GORPOBATION OF DELAVJARE REMOVABLE PEDESTAL LINER Application filed December 10,1329. Serial No. 412,952.
The present invention relates to railway running gears and embodies, more specifically, an improved pedestal mounting by means of which the pedestal which bears the axle of the truck is effectively mounted in the pedestal jaws of the truck frame.
In the mounting of pedestals upon the pedestal jaws of railway truck frames, considerable difficulty is frequently encountered 10 by reason of the fact that the sizes of the jaws vary, not only with varying designs but by reason of inaccuracies during the manufacture thereof. As a result, the complete interchangeability of parts is seriously de- 5 creased, the pedestals for a given journal box being susceptible of use in connection with only a limited number of truck frames and pedestal jaws carried thereby. Where pedestal liners are used to overcome the foregoing irregularities in designs, considerable (lllllculty has been experienced in removing or replacing liners without taking down the entire pedestal structure.
A further disadvantage of existing structures is that pedestal liners heretofore made have been of such character that they cannot be removed or replaced without dropping the entire journal box in order that the liners may be removed from the pedestal jaws.
The normal construction involving the use of pedestal liners is such that the liners overlie a horizontal flange, or flanges, formed at the base of each pedestal jaw. These flanges extend outwardly into substantially the plane of the liner and thus prevent its being dropped out for inspection and replacement. An object of the present invention, therefore, is to provide a pedestal liner construction of such character as to facilitate its application to pedestal jaws of varying sizes.
A further object of the present invention is to provide a pedestal liner which may be applied to pedestal jaws of varying sizes,
the installation and removal thereof being,
facilitated by reason of the improved structure to be described hereinafter.
A further object of the invention is to provide a pedestal liner which may be readily applied without removing the journal box or lifting the pedestal jaws, such application structed in accordance with the present in- 6Q vention.
Figure 2 is a view in section, taken on line 22 of Figure l, and looking in the direction of the arrows.
Figure 3 is a perspective view showing a pedestal liner in greater detail.
Referring to the above drawings, a designates a pedestal j aw having jaw members a and a". The jaw may be secured to the truck frame by means of bolts extending through bolt holes a in the usual manner.
At the base of each jaw member a and a horizontal flanges a are formed, such flanges normally extending toward the pedestal jaw and terminating adjacent a wear plate a shown in dotted lines in Figure 1.
In order to adjust the distance between the wear plates a in accordance with the foregoing conditions, liners Z2 are provided, such liners being secured to the respective jaws by spot welding as indicated at b. The liners are preferably formed with longitudinal grooves b for engaging the wear plates a and receiving the same telescopically. At the bottom of the grooves, rounded stop members 6 are formed, these stop members limiting the upward movement of the liners and thus properly positioning them when they are slid upwardly into position. When the stop members b have engaged-the lower extremities 90 of the wear plates a the liner is welded to the respective jaws as indicated at Z), thus readily effecting the mounting of the liners.
It will be seen that the liners may be applied by sliding them upwardly along the proper faces of the pedestal there being no obstruction to such movement. In this manner, it will not be necessary to lift the pedestal. aws from the pedestal and journal box in order that the liners may clear the horizontal flanges a as has been necessary in existing designs. To remove the liners, it is only necessary to break the weld, the liners thus being dropped from assembled position without removing the journal box from the pedestal. In the same manner, a new liner may be slid up in place and welded without the necessity of dropping the journal box from the pedestal. It will further be seen that the liners may be wedged from behind to compensate for wear of the journal boxes.
Vhile the invention has been described with specific reference to the accompanying drawings, it is not to be limited, save as defined in the appended claim.
I claim as my invention A pedestal construction for railway trucks comprising spaced pedestal jaws, plates projecting beyond the opposed faces of the aws, U-shaped liners, stops on the liners at one end thereof and extending between and lying flush with the sides thereof, and means to secure the liners to the jaws over the plates, the stops abutting the lower ends of the plates.
This specification signed this 3d day of December, A. D. 1929.
ROBERT G. ANDERSON.
