We HENRY L. MOYER, Mechanical Engineer, and GEORGE W. YOULLS, Stone
Quarryman, both of Shickshinny, in the county of Luzerne, and State of Pennsylvania,
United States of America, do hereby declare the nature of our invention for
"IMPROVEMENTS IN CAR AXLE BOXES," and in what manner the same is to be

A is a car wheel, and a is its axle. Bis the axle box, of ordinary construction,
and provided with the hinged lid 6 for filling the lower part of it with oil. C is the
pedestal, sliding within the said axle box, and provided with two oscillating rollers c
at the top to prevent jars when the car strikes against any object. A circular cavity,
or bearing, c¹, is formed in the pedestal, concentric with the axle.
Dis the axle block secured upon the axle by the key d, and E are antifriction
rollers, journaled in equidistant recesses in the circumference of the block and bearing
against the surface of the bearing c. The ends of the rollers project slightly beyond
the block and are received in the circular recesses e of the discs F and G, which bear
against the ends of the pedestal around the bearing.
To admit of the examination of the rollers E, the outer disc G is removably
connected to the axle by the screw bolt H having the square head h for turning it,
and the ratchet which prevents it from turning back.
I is a spring pawl secured to the disc by the square rivet i, and engaging with the
said ratchet, and J is a square headed stud bolt which disconnects the spring from the
ratchet when turned.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination of the axle, the axle block secured thereupon, the antifriction
rollers carried in recesses in said block, the pedestal having a circular bearing cavity

page_text: for said rollers, the discs secured to the axle against the ends of the pedestal, and
having circular recesses for the ends of the rollers, and the screw bolt for removably
securing the outer disc to the axle, substantially as set forth.
2. The combination of the axle, the axle block secured thereupon, the antifriction
rollers carried in recesses in said block, the pedestal having a circular bearing cavity
for said rollers, the discs secured to the axle against the ends of the pedestal, and
having circular recesses for the ends of the rollers, the screw bolt for removably
securing the outer disc to the axle, and provided with the ratchet at its head, the
spring pawl engaging with said ratchet, and the square headed stud bolt for dis-
engaging the said pawl when desired, substantially as set forth.
