IMPROVEMENT IN BEARlNGS FO R CAR=AXLE JOURNALS.

Specification forming part of Letters Patent No. 148,231, dated March 3, 1874; application filed December 15, 1873. v

To all whom it may concern:

Be it known that I, JAMES Mo GEE, of Steubenville, in the county of J efferson and State of Ohio, have invented a new and useful Improvement in J ournal-Bearing for Cars; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing forming a part of this specification, in which- Figure 1 shows my improvement as applied to the journal-box of the journal of a car axle. Fig. 2 is a cross-section through as w of is, that the journal itself becomes grooved at that point, and the bearing is worn and cut in the center, so that it must be taken out long before it has been worn an equal amount at Thus very large waste in the valuable material of which the bearing is formed the ends.

is made, while the journal is frequently so grooved and cut by the, unequal wear that it Before this bearing came into use, it was customary to have a bearing made of brass, which was secured in place by a cast-iron key or wedge, which was placed on top of it. In this case the entire upper face of the box It bore directly upon the plane face of the key, there being no center bearing, such has to be removed.

as is shown at a. The result of this construction was, that no allowance was made for the inequality of the track over which the journal Increased friction, heating of the journal, and a cutting of the bearing and of the journal at the ends, caused the use of these bearings to be abandoned for the one passed.

first described.

My improvement consists in forming a key, 0, of cast-iron or other similar hard metal, having a saddle or bearing-point, a, and beveling or inclined ends 0, and fitting closely upon the face of the bearin g c. It also consists in rounding or beveling the edges of the bearing 0, for the purpose of returning or feeding back the oil which may be caught thereon froin the rotating journal, so that the same is reused for the purpose of lubrication.

To enable others skilled in the art to make and use my improvement, I will describe its construction and manner of use.

I make the bearing 0 of" brass, or other suit able soft metal. The upper face of this hear ing is of polygonal shape, and with beveled or rounded edges 0 Upon the upper face 2: I place a key, made of cast-iron or other suitable hard material, having the adjoining face of similar form. Upon the upper side of this key is a raised seat or saddle, a, in which rides a corresponding projection, a, of the box h. The ends I) are sheared or inclined down from the saddle a. The whole bearing of the box comes directly on this point, and the vibration produced by the inequalities of the track are permitted by the raised saddle or seat.

The effect of my improvement is, that the rigid hard cast-iron key holds the bearing equally throughout its entire length down upon the journal (I, and does not spring up at the ends. Thus the wear upon the journal is at all times equal, the seat a allowing for the inequalities of the track. The bearing is held to the proper position by the key to receive the weight throughout its whole length.

By this construction, the wear of the bearing is equalized throughout 5 and as the journal does not wear appreciably, except under the unequal wear of the hearing, as described, thus such wear'is reduced to a minimum, and a great saving is effected.

By the rotation of the journal, the oil which is used for lubricating is thrown up on the edges of the bearing. By means of the rounded corner or bevel 0 this oil is returned to the journal again, and aids in its lubrication.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

A rigid hardmetal key, 6, provided with a raised seat, a, and inclined ends I), in combination with the soft-metal bearing 0 journal cl, and box h, substantially as described.

In testimony whereof I, the said JAMES MOGEE, have hereunto set my hand.

JAMES MOGEE.
