UNITED STATES PATENT OFFICE.
JOHN F. RODGERS, OF TROY, NEW YORK.
RAILRoAmoAR.
Specification of Letters Patent No. 5,815, dated September 26, 1848.
To all whom it may concern Be it known that I, JOHN F. RODGERS, of Troy, in the county of Rensselaer and State of New York,-have invented anew and useful Improvement in the Axles of Railroad- Carriages; and the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an end elevation of a rail road truck with my improved axle, and Fig. 2, a vertical section taken in the plane of the axis of the axle.
The same letters indicate like parts in all the figures.
The importance of having the two wheels on each axle to turn independently of one another to allow of turning curves freely without the twisting of the axle, or slipping of the wheels on the rails, has long been recognized and admitted and the remedy often attempted, but all the plans heretofore assayed have failed of success for obvious reasons. Some have assayed a separate axle for each wheel, each axle extending entirely across the truck, which necessarily places the axis of one wheel back of that of the other, and gives too much weight; others have dispensed with the axle extending from one side to the other, by making a short axle for each wheel, with a bearing for the truck on each side, which failed for want of steadiness, the leverage of such short bearings not being sufficient to resist the leverage due to the semi-diameter of the wheel when the car surges from one side of the track to the other; and others again have resorted to the expedient of making the axle in two parts with a sleeve or a disk coupling in the middle, but this too failed for the same reason as the preceding.
The object of my invention is to accomplish this long desired object by a device which avoids the defects of the plans above enumerated, and the nature of my invention consists in making the hub of each wheel with two bearings for the truck and one on each side, when this is combined with an axle extending from a wheel on one side to a corresponding wheel on the opposite side, and passing through and fitted to the hubs thereof by a ground or otherwise formed close joints so that the hubs shall turn more freely in the boxesof the truck than on the I axle. By this means the axle will give steadiness to the wheels and relieve the bearings on the hubs from the strain to which they would otherwise be exposed by the surging of the car from side to sideof the track,
and at the same time the twisting of the axle will be avoided by the turning of one or both of the hubs on the axle in passing around are provided, as in the usual'manner, with boxes (0, c) which embrace journals (d, d)
on each end of the hub (e) which is made of greater length than usual, or on a short axle inserted in and fastened to the hub,
The hubs or short axles (e) are made hollow, and adapted to receive the ends of the axles which are turned of a conical form and ground in to form snug joints that will turn only when thewheels are running on rails of different lengths as on curves, in which case one wheel must turn faster than the other. The ends of the axles are to be provided with washers and nuts (g, g) to prevent the hubs or hollow axles from slipping ofi'.
From the above arrangement it will be seen that the wheels can turn independently of one another on the axle when passing and the short hearings on each side of the The tendency. to break i wheels will be protected from overstrain and sired end is accomplished without encountering any of the objections which have been axle passing through the hubs or short axles, fatal to other devices heretofore applied to substantially as herein described and for 10 this purpose. the purpose specified.
WVhat I claim as my invention, and desire 5 to secure by Letters Patent, is H RODGERS Supporting the truck on journals made Witnesses: each side of the Wheels on the hubs or short CHAS. M. KELLER, axles, When this is combined with the long CH. L. FLEISCHMANN.
