UNITED STATES PATENT OFFICEo WILLIAM J. MANKER, OF SEDALIA, MISSOURI.
IMPROVEMENT IN CAR-AXLE BCXES.
Specification forming part of Letters Patent No. 138,265, dated April 29, 1873 application filed September 26, 1872.
To all 'whom it may concern:
Be it known that I, WILLIAM J. MANKER, of Sedalia, Pettis county, State of Missouri, have invented certain Improvements in Car- Axle Boxes, of which the following is a specication: y
The object of this invention is to provide a means of cooling the journals of car-axles 5 and it consists in such a construction of the caraxle box and the bearing-piece that when the car is in motion a constant current of air will be forced upon the journal, ashereinafter more fully described.
In the drawing, Figure l is a vertical transverse section of a car-axle box With my improvements, and Fig. 2 is a plan view of the bearing-piece.
In the axle-box b, of ordinary construction, is arranged a bearing-piece, c, having a semicylindrical bearingsurface, which lits upon the journal of the axle a. This bearing-piece c has a passage-way, d,'extendin g transversely through it, and a groove or channel, c, extending longitudinally of its semi-cylindrical bearing-surface, both of which communicate with i a centrally-located air-chamber, g, which opens upon the journal. At each side of the box b a funnel, f, is attached, which communicates with the interior by means of a small openin g, d', corresponding in location, and communicating with the passage-way d in the bearingpiece. This passage-way d is made wide to allow for any play of the bearing-piece in the box and preserve communication with open ings d.
When the car is in motion one of the funnels f will catch the air and conduct it th rough opening d into air-passage d and chamber g, and along the grooved channel c, egress being allowed through the opening and funnel opposite. By this means a constant current of air will be supplied to the entire bearing-surface, and the journal thereby, to a great extent, be prevented from heating.
When the car is at rest the air-chamber g and channel c, with the outwardly-communicating passage d, will tend to cool the journal should the same have become at all heated while in motion.
Wire-gauze covering, or other devices, may be used in connection with the funnels to pre vent cinders, &c., from gaining entrance into the axle-box.
I claim as my inventionl. In a car-axle box, a bearing-piece provided with an air chamber or chambers and communicating passages opening upon the journal, constructed substantially as described, for the purpose specified.
2. The combination ot' a bearing-piece, provided With chamber or chambers and communicating-passages, With a casing or shell provided With funnels, or equivalents, for catch ing and conducting the external air into the chambers and passages, substantially as described. V
W. J. MANKER. Witnesses:
